sharp lcd touch screen alarm clock brands

I’m a writer at Design Milk, and since 2006 I’ve been writing about home design for a multitude of design-focused outlets, including Apartment Therapy, Lonny, Metropolis, and Design Sponge. I’ve also written several guides here at Wirecutter, including on bedside lamps, floor lamps, bed frames, and patio furniture. Previously, as an industrial designer, I designed children’s toys and furniture, and this allowed me to learn the ins and outs of mass-market product design—from conception to manufacturing. I have an uncanny ability to wake approximately one minute before any alarm, but I’m still paranoid enough to set one as a backup.A budget digital alarm with a large face: DreamSky Compact Digital Alarm Clock

This budget digital alarm clock does so much for so little. It has the largest numerical display of the clocks we tested, two USB ports, and easy-to-use tactile controls (which take the guesswork out of changing settings).

Why it’s great: If you’re looking for an alarm clock that does a lot on the cheap, the DreamSky Compact Digital Alarm Clock is both an alarm clock and a USB charging station. Something that really stood out with this model, versus other clocks we tested: The DreamSky has an enormous digital display (each number is 2 inches tall) that stretches across the entire front of the clock. Although I’m nearsighted, with basically mole-like eyesight, I could read this clock clearly from a distance—without wearing glasses or contacts.

Some digital alarm clocks we tested—specifically those with lots of extra features and controls, such as the Philips Wake-Up Light—required a detailed review of manuals to get them up and running. The DreamSky, on the other hand, was plug and play: The clock was easy and intuitive to set and adjust, with clearly labeled buttons for time and alarm and two physical dials for volume control and display brightness. The DreamSky was the only clock we tested that had such a wide range of customization options—it’s simple to literally dial in your personal preferences. The snooze button isn’t a physical button, but there’s a touch-sensitive surface that shushes the alarm in nine-minute increments.

You should know that this alarm clock is not fully battery-operated—two backup AAA batteries are responsible only for keeping time and alarm settings, in case of a power outage. There are two USB ports in the back—one to charge most mobile devices with 5 V output and the other to power the clock via USB (or you can plug directly into the wall).

Flaws but not dealbreakers: The DreamSky logo emblazoned at the top (underneath the snooze button) is downright ugly. The plastic case and buttons feel every bit like what you’d expect from a $20 device. The batteries protect only time and alarm settings, in case of a power outage; for a full display, you have to plug in the clock or keep it connected via USB cable.

The Lenovo is an affordable smart alarm clock that won’t take up much space. And with its built-in Google Assistant, it can be operated completely hands-free.

Best for: Anyone looking for a compact digital alarm clock that offers time, day, and weather info at a glance, and those who prefer using voice controls over physical buttons.

Why it’s great: Lenovo offers two Smart Clocks, the Lenovo Smart Clock and its cheaper sibling, the Lenovo Smart Clock Essential. We liked the smaller and more affordable of the two because its options are true to its name—Essential—with time, weather, and day easily viewed at a glance across its 4.5-inch auto-brightness-adjusting LED display.

Most everything this alarm clock can do is hidden, accessed using its built-in Google Assistant voice controls or with the Google Home app. Even though the clock is outfitted with four evenly distributed buttons—for volume, turning on music, and the alarm settings—they are obscured from view due to the angled wedge design. Unless you’re looking at them from above, the buttons are discernible only by touch, and I often fumbled at night or in the early morning while trying to turn on music or adjust the volume. There’s also a tap at the top to enable the snooze feature, but it sometimes required another touch to register. To set the alarm, adjust the volume, or turn on the night-light, it was always much easier to summon help with a “hey, Google …” instead. Fortunately, the clock’s two microphones (one in the front, the other in the back) are very sensitive and able to discern commands, even when we used a hushed volume at night. And though the clock’s single-speaker output can be a bit tinny for playing music, it can get surprisingly loud and is just fine for alarm tones and answering Google Assistant prompts.

The clock’s compact size is ideal for anyone with limited space. Even so, Lenovo included a USB 2.0 Type-A port in the back for charging devices (albeit at a slow rate, which is best for overnight charging). There’s also an oval-shaped night-light in the back. But the output is fairly dim, even at the brightest setting, so it’s best used as an ambient light to help you find your way in the dark.

Flaws but not dealbreakers: The clock’s physical buttons make a satisfying click when pressed. But because of their angled pitch, they’re small and hard to discern. The tap-to-snooze feature can be finicky.

This alarm clock has a unique tip-proof, triangular design, and you can set the display to turn off automatically after 10 seconds (just tap the clock’s face to wake it up again).

Best for: Those who prefer the look of wood over plastic and who value unfussy contemporary design—as well as those who want an alarm clock that displays the time, date, temperature, and humidity at a glance.

Why it’s great: The Oct17’s triangular-shaped wood body looks much nicer than one might expect from a budget clock. In fact, it’s more attractive than many pricier clock options we considered. (It’s also the only clock we found that’s virtually impossible to tip over.) This model is very affordable, and yet compared with the cheap feel of the DreamSky and Capello alarm clocks, the Oct17 seems upscale. The clock’s wood-grain finish has a great feel, and its cool “now you see me, now you don’t” LED display shines from beneath its veneer.

The Oct17 displays more information at a glance than any other clock we recommend, showing the time and date (alternating) alongside the temperature and humidity level—all without requiring an internet connection. If you’re bothered by ambient light glowing from your clock, the Oct17 has three brightness settings. And it’s the only display we found that you can set to turn off completely after 10 seconds. But when you need to know the time again, a clap of the hands or a tap on the front face will reawaken the clock for 10 seconds.

If you don’t wake at the same time each day, this is the digital alarm clock for you: It has three separate alarms, including one you can set to skip on weekends (to allow for sleeping in).

Flaws but not dealbreakers: Navigating the clock’s mode settings and feature adjustments proved unintuitive, requiring more button presses than a Street Fighter move combination.

Why it’s great: The RCA RCD30 is an affordable digital alarm clock with a bright display, an easy-to-use button layout, and an alarm loud enough to wake even heavy sleepers. It’s also the least expensive model we tested, making it an easy choice when you need something cheap and dependable, like for a guest room or a vacation rental.

The RCA is a basic unit, but it has all you really need in an alarm clock. It’s one of the smallest clocks we considered, so it won’t take up much room on your nightstand. But it’s also easy to read, with a 3.75-by-1.4-inch illuminated display that’s visible in daylight and at night from at least 20 feet away. The large display size is a boon for people who wear glasses because there’s no need to fumble for them in order to check the time. If a big display keeps you up at night, know that the RCD30 does offer a dimmer setting.

The no-frills RCA is also easier to use than other, more complicated clocks we tested. It has a large snooze button across the top, so you can usually hit it without much trouble. On the back, there are three switches: one for setting the time and alarm, one for dimming the front display, and one for turning the alarm on and off. The alarm emits a loud, constant beep that can be heard from at least 20 feet away. That wake-up call continues until you shut off the alarm or hit snooze (which provides an extra nine minutes of slumber every time you press it, for well over an hour).

The RCD30 also comes with the option for backup via a 9-volt battery, so you won’t lose your settings if the power goes out at 2 a.m. As with most of the alarm clocks we tested, when the RCD30 is using only battery power, it will not display the time, but the alarm will still go off.

Flaws but not dealbreakers:A few of the alarm clocks we reviewed have up and down buttons for setting the time. The RCA does not. The minute and hour buttons go in only one direction, so if you get distracted while setting the time and go too far, you’ll need to cycle through again. This is not unique to the RCA, though; setting the alarm on the Alessi Optic 02 B presented a similarly frustrating, “careful, don’t miss it” experience.

This was one of the least sleep-disruptive digital alarm clocks we tested. Whether it’s the night-light, the snooze button, or the sound of the alarm tones, every detail feels like it’s been refined to reinforce a state of calm.

Why it’s great: The Loftie can fool you into thinking you’re waking up of your own accord every morning, rather than being forcibly annoyed out of bed. Of all the alarm clocks we tested, the clock’s selection of five ambient compositions best induced the sensation of arising alongside the natural cues of the morning—sounds of birds, ambient tones, morning temple bells. After nine minutes, the Loftie follows up the first alarm with an ever-so-slightly more-insistent “get up” chime. (After first using the Loftie, I wrote down that “I felt like I had arisen to a morning directed by Terrence Malick, all contemplative mood and relaxing stillness.”) There’s the option to set different alarms scheduled for different days of the week, as well as a multitude of alarms you could set as reminders throughout the day—to get up occasionally, exercise, or walk the dog, among other everyday tasks.

You do not need your phone to use the Loftie—you can play everything, including podcasts, right from the device. But you do need to use the Loftie app on your phone to get the clock online during setup; this allows the clock to receive regular updates. Photo: Rozette Rago

Of clocks we’ve tested, this one’s display isn’t the largest or the brightest. But it’s clear, and it automatically sets the time once connected to a Wi-Fi network. We also liked the clock’s all-black exterior (it comes in a white and black option, too), which is free of distracting lights or branding. There’s an adjustable night-light hidden at the base that’s easily turned on and off, using the large button on top of the clock (it also works as the snooze button). You won’t be able to read using the light, but it’s bright enough for when you’re fumbling for your glasses or going to the bathroom in the middle of the night. The two other buttons are for setting the alarm, accessing brightness and volume settings, setting the duration of the sleep timer, and choosing alarm tones. The Loftie isn’t “smart” like other smart alarm clocks, in that you won’t be served the news or the weather with the aid of a voice assistant. But on a regular basis this clock can get additional features delivered via Wi-Fi updates. For instance, we discovered one night that there were a few more soothing classical compositions to wake up to than we’d had the day before and that alarm-scheduling options had been expanded. The developers recently added Bluetooth speaker functionality and are promising Spotify connectivity and additional sounds as features that are “coming soon.” We’ll update this guide when—and if—these features appear.

Flaws but not dealbreakers: The Loftie was $165 when we first tested it, but the price has dropped to $150. We still think it’s a pretty penny to pay for any device, let alone an alarm clock with a purposely edited selection of features. The numerical display is legible up close, but it’s slightly dimmer when viewed off-center. And, for nearsighted sleepers like us, we wish there were an option to increase the display size.

A serene alternative to loud alarms, this clock induced a gentler wake-up (a simulated sunrise accompanied by birdsong) than any other clock we tried. But it’s pricey, and it’s harder to navigate than the other clocks we tested.

Best for: Anyone who hates being jolted awake each morning with a wailing alarm, and those who prefer easing into consciousness with increasing luminosity.

Why it’s great: A top pick in our guide to sunrise alarm clocks, the Philips SmartSleep Wake-Up Light HF3520 is still our favorite sunrise alarm clock for anyone who hates being woken abruptly. Over the span of 30 minutes, the luminous LED orb produces a convincing simulation of dawn or dusk. It provides a kinder, gentler wake-up than any other alarm we recommend, and it’s the only clock we tested that can help lull you to sleep at night. The Wake-Up Light also includes more alarm options than most clocks we tried, with five nature-themed tones, along with a built-in FM tuner and a backup alarm. (However, navigating the clock’s touch surface and icon-based menu system isn’t very intuitive, and not always responsive.) Our favorite setting was a combination of the simulated sunlight paired with the convincing sounds of cheerful chirping birds.

We also found the clock’s light sufficiently bright enough to work as a decent reading lamp, making the Wake-Up the only clock we recommend that can do so. At 8 inches wide, this model takes up a lot more room on the nightstand than other clocks we tested. But when you think of the Wake-Up as a combination alarm clock and bedside lamp, it presents a pretty efficient use of space.

Flaws but not dealbreakers: Despite the Wake-Up Light’s overall size, its numerical digital display is less than an inch tall and so not as easy to read as those of the other clocks we tried (especially with its light at full brightness). The secondary set of tactile buttons across the unit’s top are more intuitive to use than the icons on the clock’s display, but they’re small and all the same size, so it’s easy to press the wrong button. The FM radio is a plus, but considering that the clock is our second-most-expensive pick, the silver-dollar-sized rear-facing speaker is tinny and disappointing. The LED bulb is rated to last seven years with regular use. But it cannot be replaced, so over time the clock could lose its most distinguishing feature.

The Riki is an analog clock that’s easy to read and to set (with one of the most pleasant alarms that will still wake you up). It’s ideal for light sleepers who want to banish electronic distractions from the bedroom.

Why it’s great: If you want a dependable alarm clock with a timeless analog design that’s dead silent and easy to use, the Lemnos Riki checks all of those boxes. The only alarm clock among our picks with a design-award pedigree, the sedate beechwood Riki was designed by Japanese modernist Riki Watanabe, whose work was known for being simple yet functional. The Riki’s prominent face has half-inch-tall numerals and large hour and minute arms, so it’s easy to read—even in dim light and from a distance. The clock’s sole button consolidates the light and snooze functions (doling out extra sleep in four-minute increments), and we found it effortless to use, even with our eyes closed. When you press the button, the clock illuminates just enough to make the face legible (a big plus for those of us who like to peek at the time before we have any real intention of waking up). The brightness level seemed more akin to candlelight than to the intrusive modern glare produced by the LED- or LCD-backlit displays on other clocks we tested. Even the next-dimmest night-light (on the Marathon Analog Desk Alarm Clock with Auto-Night Light) seemed much too bright after we’d acclimated to the Riki’s tranquil illumination.

Although it looks perfectly round, the clock actually has a subtle indentation on its base that keeps it from rolling away—and from moving when brushed or bumped. And because this clock is battery-operated (it needs only a single AA battery), there are no cords to worry about. In addition to its snooze button, the straightforward Riki has just three controls: an on/off switch for the alarm and two dial knobs to set the time and the alarm.

If the tick-tock of some clocks’ mechanical movement tends to keep you awake, rest assured that this clock is completely silent—something we can’t say about the percussive passing of time produced by the Alessi Optic 02 B or the faint bzzzz emanating from the Marathon Analog Desk Alarm Clock with Auto-Night Light. The only sound the Riki makes comes from its alarm, which is loud enough to wake you without being annoying.

Flaws but not dealbreakers:The Riki isn’t cheap, and it’s gone up a bit in price since we first tested it. Even though this clock is still available on Amazon and at various other retailers, the Lemnos site currently lists the Riki as “archived,” so we’re investigating whether it may have been discontinued permanently. We will update this guide as soon as we know more.

Setting the Riki’s alarm to a specific hour is fairly simple to do, but setting it to an exact minute is more of an estimate, due to the clock’s dial face. The ABS resin snooze-and-light button matches the color of the beechwood clock case, but it isn’t made of wood.

Alarm clocks may seem a bit old-fashioned, since everyone and their grandmother now uses a phone as an alarm. A search for “alarm clock” on Amazon returns a paltry seven pages of models to choose from, many only minutely different from the next (and most so ugly that the thought of sleeping near them is enough to induce mild insomnia).

Produces a pleasant alarm tone:The ideal alarm will wake you up without creating a jarring effect. We favored models with pleasant tones and the option to change them based on personal preference.

Dimmable: A persistent, noticeable bright light can be a detriment to falling asleep. We highly recommend a clock with the option of manually or automatically dimming the display.

Simple to set: Accessing alarm on/off settings or adjusting features like snooze, brightness, and alarm volume shouldn’t require a PhD or a YouTube tutorial.

Unobtrusive: An alarm clock should not be the first thing you notice in a bedroom—perhaps it should even be the last. Leave the statement pieces to the living room.

Extra features: Radio, USB ports, Bluetooth and internet connectivity, multiple alarms, alarm sound and tone options, and a backup battery are all welcome (but not necessary).

In 2018, after reading through customer reviews on Amazon and other retailers—and focusing particularly on the qualities listed above—we called in the 10 most promising alarm clocks. We used each clock for a few days and nights. In 2021, we again scoured retailers and called in four more alarm clocks to test. We tested each model in our bedrooms, with the alarm set half an hour earlier than our usual wake-up time, to ensure the clock’s alarm tone was responsible for breaking our usual sleep cycle as well as to allow us to use each clock’s snooze function while still groggy. We also kept an eye out for cosmetic defects, and we inspected the durability of materials and construction, imagining the litany of abuse an alarm clock may have to endure over its lifetime. Aside from the largest clock (the Philips Wake-Up Light), our picks are small; they should fit on most nightstands and won’t slide or knock over easily.What to look forward to

We’re keeping an eye on the OneClock, a supposedly built-to-last-a-lifetime analog alarm clock that was crowdfunded on Indiegogo. But at a $300 retail price, it’s definitely not cheap. The pre-production sample we saw seemed promising, but we’ll update this guide once we’ve tested the publicly available version. We’re also going to look at the Echo Dot with clock in our next round of testing, to see how it compares to the Lenovo Smart Clock Essential.Other good alarm clocks

If you’re just looking for a basic and affordable AM/FM radio clock: Consider the Sangean RCR-5, a back-to-basics dual-alarm clock radio that costs less than $50. The Sangean scores solidly online with owners, but we found the clock’s cheap, glossy plastic finish and overly conspicuous logo distracting and reminiscent of models found on drugstore electronics shelves. It made us appreciate the similarly priced Lenovo Smart Clock Essential’s tasteful simplicity that much more.

If you’re looking for a smart alarm clock with a color screen: Consider the Lenovo Smart Clock, which is just barely larger than its more affordable, monochromatic, non-touch Essential counterpart but combines a punchy, full-color touchscreen display with the same Google Assistant hatful of tricks. The introduction of another bright color screen in the bedroom isn’t a great idea, though, and the few other extras the Smart Clock adds—a selection of user-customizable faces and more alarm options than in the Essential—do not really justify its price.The competition

Amazon Echo Spot: Amazon discontinued the Echo Spot, so we can no longer recommend it. Although it was the most expensive clock we tested, we loved how small and simple it was to set up. It also offered more features than any other clock in our tests. Amazon has folded features from the Echo Spot into its smart displays, like the Echo Show 8 and the cheaper Echo Show 5 (which you can read more about in our guide to smart displays). We also recommend the Echo Dot in our guide to Alexa speakers, one of which comes in a version with an LED clock display.

Marathon Analog Desk Alarm Clock with Auto-Night Light: The Marathon has many great features. In addition to its compact design (the clock measures 3.5 inches wide by 1.5 inches deep), the Marathon features a sensor night-light, dead-quiet movement, a clearly marked alarm and snooze buttons, and a low-glow light that’s similar to (but not quite as good as) the one on the Riki. Its one and only shortcoming was legibility: The clock’s printed numerals were small and hard to read at a glance. We’d still recommend it if you want a battery-operated alarm clock that’s easy to throw in your luggage.

Lexon Flip On/Off Alarm Clock: (Of note: This clock has now been replaced by the Lexon Flip Plus; the size hasn’t changed, however.) The Lexon Flip is fun to use and has a novel design that works well: To turn the alarm on or off, you flip the entire clock over, instead of pressing a button or a switch. Each side is clearly marked, with “on” written across the clock’s rubber coating on one side and “off” written across the other side. The Flip (which is nearly impossible to tip over) takes up little space, but its small size also means it isn’t as legible as we’d like for an everyday alarm clock. Its LCD display is hard to see in standby mode, and it’s easy to read only with the backlight on. Also, its high-pitched digital tone is effective yet annoying.

MoMA Alume Cube Clock: We liked the Alume for its compact, 2.75-inch minimalist silver-cube design. It should fit on any surface with plenty of room to spare, displaying the time, date, and temperature with a snap of the fingers or a tap on its top. Where the clock comes up short: the absence of snooze or dimming options (the display turns completely off between snaps or taps) with an LED display that glows a bit too cold and bright for tired or still-waking eyes. If you do like this design, there are several knockoffs—with similar features—for a lot less.

Capello Round Time Table Clock: The Capello is a small and lightweight plug-in alarm clock with an easy-to-read LED display and a stylish gray-fabric front. A USB port in the back works great for overnight charging, but the listed “option to plug in your phone so you can listen to music” didn’t really work for us (with an iPhone). And the clock’s lightweight plastic construction made it easy to knock over. The snooze button isn’t a real button—touches or light taps won’t register. Snoozing the alarm requires a firm, palm-down press across the entire clock. If you’re sensitive to light, you should note that even at the dimmest of this clock’s three settings, the LED display was distracting. We eventually had to turn it face-down.

Alessi Optic 02 B Alarm Clock: This now-discontinued model from Alessi was an example of high design being hampered by low-quality features. This clock was too audible to be a peaceful bedside companion, producing a tick-tock sound so loud that it bothered us even when we were in the next room. No doubt, the Italian space-age design is eye-catching, but having this clock near the bed made the passing of time a torturous, second-by-second affair. And we found its plastic construction flimsy, with tiny and difficult-to-set dial controls that had more in common with a cheap, drugstore alarm clock than something sold for many times the price.

I have a love-hate relationship with my alarm. I rely on it to ensure I get up in the morning and perform important tasks throughout the day, but when it sounds in the morning, I glare at it with the fury of a thousand suns.

Picking the best alarm clock for you can be tough, especially with so many features, price points and brands. We did the testing for you, so you can rest easy knowing you have your ideal alarm clock. Here are our picks for the top six best alarm clocks you can buy right now. As well as some others we still recommend.Best alarm clocks

If you"re looking for a simple, straightforward alarm clock, you"ll like the Travelwey Home LED alarm clock. You"ll like its reasonable $20 price tag even more. There are only a few easy-to-use buttons and a prominent classic red time display. It doesn"t have all the bells and whistles that some of the other alarm clocks on the list have, but if you"re looking for a simple alarm clock to get the job done, Travelwey Home LED is a solid pick.

You can adjust the Travelwey alarm clock"s brightness, but during testing, we found that it doesn"t cast a glow that would disrupt your sleep at the highest setting. It also has a night-light feature if you"re into that. It has a standard 9-minute snooze time, and you can switch between a soft or loud sound setting.

Travelwey Home LED alarm clock"s best features:Travelwey is the best overall alarm clock because it"s basic but dependable. All the classic features are well implemented.

The alarm clock industry has changed a lot. No longer is your alarm clock just something that wakes you up. Many smart alarm clock options function as an interactive hub where you can access your alarms, weather and music. The Amazon Echo Show 5 is the best smart alarm clock, thanks to its varied features and voice assistant connectivity.

This smart alarm clock allows you to use your music or a customizable tone as your alarm. If that"s not enough, it also has a sound ramp-up feature designed to gracefully bring you out of sleep instead of scaring you awake. The screen also gradually gets brighter, starting fifteen minutes before your alarm sounds.

You can use voice commands to access the Alexa voice assistant. This smart alarm clock"s touchscreen allows you to check the weather, make video calls or control your smart home. It"s more than an alarm clock. If you want to use your alarm clock for everything, consider the Amazon Echo Show 5.

Amazon Echo Show 5"s best features:Amazon Echo Show 5 is a highly customizable alarm clock that allows you to use your music or sound. The ramp-up screen and sound feature are less jarring than traditional alarms.

Sunrise alarms are designed to gradually wake sleepers up with light rather than a blaring alarm. The best of is the Philips HF3500. We found it to be one of the best sunrise alarm clocks thanks to its orange display, light function and price tag.

Visually, it"s unique -- it looks like a UFO with a kickstand. There are simple buttons at the center, under the time display. But the majority of the surface area is devoted to the light feature. Thirty minutes before your alarm time, this Philips sunrise alarm will gradually increase its brightness level until it reaches the maximum you set. To ensure you wake up, it also starts beeping with increasing intensity.

Things to consider:Snoozing the Philips HF3500 sunrise alarm clock is a little weird initially. There"s no button. Instead, you press the top half of the light.

Not everyone wants to spend a lot of money on their alarm clock, especially if you don"t want all the added features. That"s where the RCA RCD30 alarm clock comes in. Similar to the Travelwey, the RCA RCD30 is our pick for the best budget alarm clock because of its simple design.

It features the classic red number display that offers two brightness levels. During testing, we found that neither level glows to the point where it would interrupt your sleep. It has an easy-to-find snooze button. It doesn"t have any added features like a night light or lights. It is a straight-to-the-point classic alarm clock that will get the job done.

Heavy sleepers can be almost impossible to get up. If you"re someone who sleeps through their alarm and needs something more heavy-duty, we recommend the Sonic Alert Sonic Bomb alarm. It"s one of the best alarm clocks for heavy sleepers.

The Sonic Alert Sonic Bomb alarm comes with two parts -- the classic display and incredibly loud buzzer and the vibrating attachment that you can slip under your pillow. You can customize the alarm with controls our team thought were easy to figure out.

Finding a kids" alarm clock that meets all your child"s needs can be hard. The Hatch Restore alarm clock is a sound machine and smart light in one. This alarm clock for kids has many features that other options can"t compete with. Not only do you get white noise sounds, but there"s a digital alarm clock display and soft control buttons.

The Hatch Restore Sound Machine and Smart Light can grow up with your child. It has an app you can access on your phone, which allows you to personalize the clock to suit your growing child. You can create sleep and wake routines with light dimming or brightening for your child.

Hatch Restore Sound Machine"s best features:Hatch Restore Sound Machine is one of the best alarm clocks for kids because it"s packed with helpful features and allows for personalization.

We"ve tested a lot of alarm clocks, not all of which made this best alarm clock list. But they"re still worth mentioning and might be the right fit for you.

The Lenovo Smart Clock also has a sunrise feature, meaning the screen gets brighter 30 minutes before your scheduled wake-up time. One drawback of the Lenovo Smart Clock 2 is the display always glows, no matter which clock face you choose. Read our

Lenovo Smart Clock Essential is a basic smart alarm clock with Google Assistant, but not an interactive screen. You can see the time, set alarms and see the weather. The physical buttons do the basics of muting the microphone or controlling the volume. But that"s about it. Still, the $50 price makes it an appealing option even if it doesn"t have all the extra features. It"s comparable to the Nest Mini or the Echo Dot with Clock. Read our

The Amazon Echo Dot with Clock displays the time, alarms and weather, with the display"s brightness adapting to the room. It"s still a smart speaker first, responding to voice commands Amazon Echo Dot with Clock review for everything you need to know.

If you"re someone with impaired vision, you"ll like the large-print design of the American Lifetime Day Clock. You can program your alarms to include reminders that will be displayed on the screen, like "time to take your medications." That said, it isn"t the best alarm clock we"ve tested. There is no snooze button. The display is bright, even in the dimmest setting. You must scroll through a menu to schedule alarms, which can get confusing.

If you"re someone who values all the bells and whistles, consider the $50-ish iHome iBT29BC. It has a built-in radio and two alarms; it doubles as a Bluetooth speaker and even has an auxiliary cable. The iHome IBT29BC allows you to customize it by adjusting the colors and sounds it uses to wake you up. The light doesn"t adjust, but it does come on when your alarm sounds. This alarm clock is a jack of all trades but doesn"t shine in any category.

The HomeLabs Home Sunrise Alarm Clock has many features -- the light changes colors and fades up. There"s a radio with various wake-up sounds, including classical music and nature sounds. With this Alarm, you get what you pay for, the buttons aren"t the most responsive and it is more difficult to set alarms. The brightness ramp-up isn"t as seamless as other options, but for only $25, it"s a good option.

There are a lot of features that go into alarm clocks, and we tested them all. When testing the best alarm clocks, we assessed each option on their display, sound and ease of use. We considered how long the snooze button was set for, how customizable the alarm is and additional light features you need to know about.

Once we had the data of each alarm clock compiled, we made sure to compare each alarm clock to each other to ensure this best alarm clock list is the best reflection of the current market.

When shopping for an alarm clock, it"s easy to get overwhelmed with hundreds of options. It"s understandable. A wide variety of alarm clocks are available that differ by features and price. Keep these things in mind when looking for the best alarm clock for you:Price: The alarm clock market is wide -- with both budget and luxury options. Defining your budget early will help you narrow down your options and keep you from getting wowed by features you may or may not need.

Features: First and foremost, you must decide if you want to stick to the basics or dive into the ocean of alarm clock features. Do you want your alarm clock to charge your phone? Play music? Or would you rather just have a basic alarm clock with a clearly labeled snooze button? The good news is that there are so many combinations of features that you"re sure to get an alarm clock that fits your needs.

Display: Deciding how elaborate the display of your alarm clock is also important. Some have super bright screens, while others have simple red or orange numbers that don"t cast as much glow.

How it wakes you up:No longer are you limited to a loud blaring screech to wake you up. Alarm clocks have come a long way and now offer gentle wake-up with sound or light that progressively gets louder or brighter. But if you"re a heavy sleeper, you may want something louder.

How "smart" you want it to be: Many of the best alarm clocks are compatible with Alexa, Google Assistant and Apple"s Siri, making scheduling alarms easy.

Alarm clocks for heavy sleepers tend to be much louder than the average alarm clock; some even vibrate your bed. Our testing found that the Sonic Alert Sonic Bomb is the best alarm clock for heavy sleepers. It"s loud and it has a vibrating attachment that you can slip under your pillow. Not to mention, it"s budget-friendly.

Light sleepers have the flexibility to choose just about any alarm clock out there. The best alarm clock for light sleepers will come down to preference. If you want one that plays your music to wake you up, consider a smart alarm like the Amazon Echo Show 5. If you want a sunrise alarm that uses light to gently wake you up, try the Philips HF3500.

You can use your phone as your alarm clock as long as you remember to keep it charged enough to last a night. Alarm clocks ultimately make for better options, though, because they"re plugged in with backup batteries, so you never oversleep. Additionally, using your phone as your alarm keeps it close to the bed, which may tempt you to use it late at night. If you prioritize your sleep quality, go with an alarm clock.

A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directlybacklight or reflector to produce images in color or monochrome.seven-segment displays, as in a digital clock, are all good examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from a matrix of small pixels, while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character positive LCD with a backlight will have black lettering on a background that is the color of the backlight, and a character negative LCD will have a black background with the letters being of the same color as the backlight. Optical filters are added to white on blue LCDs to give them their characteristic appearance.

LCDs are used in a wide range of applications, including LCD televisions, computer monitors, instrument panels, aircraft cockpit displays, and indoor and outdoor signage. Small LCD screens are common in LCD projectors and portable consumer devices such as digital cameras, watches, digital clocks, calculators, and mobile telephones, including smartphones. LCD screens are also used on consumer electronics products such as DVD players, video game devices and clocks. LCD screens have replaced heavy, bulky cathode-ray tube (CRT) displays in nearly all applications. LCD screens are available in a wider range of screen sizes than CRT and plasma displays, with LCD screens available in sizes ranging from tiny digital watches to very large television receivers. LCDs are slowly being replaced by OLEDs, which can be easily made into different shapes, and have a lower response time, wider color gamut, virtually infinite color contrast and viewing angles, lower weight for a given display size and a slimmer profile (because OLEDs use a single glass or plastic panel whereas LCDs use two glass panels; the thickness of the panels increases with size but the increase is more noticeable on LCDs) and potentially lower power consumption (as the display is only "on" where needed and there is no backlight). OLEDs, however, are more expensive for a given display size due to the very expensive electroluminescent materials or phosphors that they use. Also due to the use of phosphors, OLEDs suffer from screen burn-in and there is currently no way to recycle OLED displays, whereas LCD panels can be recycled, although the technology required to recycle LCDs is not yet widespread. Attempts to maintain the competitiveness of LCDs are quantum dot displays, marketed as SUHD, QLED or Triluminos, which are displays with blue LED backlighting and a Quantum-dot enhancement film (QDEF) that converts part of the blue light into red and green, offering similar performance to an OLED display at a lower price, but the quantum dot layer that gives these displays their characteristics can not yet be recycled.

Since LCD screens do not use phosphors, they rarely suffer image burn-in when a static image is displayed on a screen for a long time, e.g., the table frame for an airline flight schedule on an indoor sign. LCDs are, however, susceptible to image persistence.battery-powered electronic equipment more efficiently than a CRT can be. By 2008, annual sales of televisions with LCD screens exceeded sales of CRT units worldwide, and the CRT became obsolete for most purposes.

Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, often made of Indium-Tin oxide (ITO) and two polarizing filters (parallel and perpendicular polarizers), the axes of transmission of which are (in most of the cases) perpendicular to each other. Without the liquid crystal between the polarizing filters, light passing through the first filter would be blocked by the second (crossed) polarizer. Before an electric field is applied, the orientation of the liquid-crystal molecules is determined by the alignment at the surfaces of electrodes. In a twisted nematic (TN) device, the surface alignment directions at the two electrodes are perpendicular to each other, and so the molecules arrange themselves in a helical structure, or twist. This induces the rotation of the polarization of the incident light, and the device appears gray. If the applied voltage is large enough, the liquid crystal molecules in the center of the layer are almost completely untwisted and the polarization of the incident light is not rotated as it passes through the liquid crystal layer. This light will then be mainly polarized perpendicular to the second filter, and thus be blocked and the pixel will appear black. By controlling the voltage applied across the liquid crystal layer in each pixel, light can be allowed to pass through in varying amounts thus constituting different levels of gray.

The chemical formula of the liquid crystals used in LCDs may vary. Formulas may be patented.Sharp Corporation. The patent that covered that specific mixture expired.

Most color LCD systems use the same technique, with color filters used to generate red, green, and blue subpixels. The LCD color filters are made with a photolithography process on large glass sheets that are later glued with other glass sheets containing a TFT array, spacers and liquid crystal, creating several color LCDs that are then cut from one another and laminated with polarizer sheets. Red, green, blue and black photoresists (resists) are used. All resists contain a finely ground powdered pigment, with particles being just 40 nanometers across. The black resist is the first to be applied; this will create a black grid (known in the industry as a black matrix) that will separate red, green and blue subpixels from one another, increasing contrast ratios and preventing light from leaking from one subpixel onto other surrounding subpixels.Super-twisted nematic LCD, where the variable twist between tighter-spaced plates causes a varying double refraction birefringence, thus changing the hue.

The optical effect of a TN device in the voltage-on state is far less dependent on variations in the device thickness than that in the voltage-off state. Because of this, TN displays with low information content and no backlighting are usually operated between crossed polarizers such that they appear bright with no voltage (the eye is much more sensitive to variations in the dark state than the bright state). As most of 2010-era LCDs are used in television sets, monitors and smartphones, they have high-resolution matrix arrays of pixels to display arbitrary images using backlighting with a dark background. When no image is displayed, different arrangements are used. For this purpose, TN LCDs are operated between parallel polarizers, whereas IPS LCDs feature crossed polarizers. In many applications IPS LCDs have replaced TN LCDs, particularly in smartphones. Both the liquid crystal material and the alignment layer material contain ionic compounds. If an electric field of one particular polarity is applied for a long period of time, this ionic material is attracted to the surfaces and degrades the device performance. This is avoided either by applying an alternating current or by reversing the polarity of the electric field as the device is addressed (the response of the liquid crystal layer is identical, regardless of the polarity of the applied field).

Displays for a small number of individual digits or fixed symbols (as in digital watches and pocket calculators) can be implemented with independent electrodes for each segment.alphanumeric or variable graphics displays are usually implemented with pixels arranged as a matrix consisting of electrically connected rows on one side of the LC layer and columns on the other side, which makes it possible to address each pixel at the intersections. The general method of matrix addressing consists of sequentially addressing one side of the matrix, for example by selecting the rows one-by-one and applying the picture information on the other side at the columns row-by-row. For details on the various matrix addressing schemes see passive-matrix and active-matrix addressed LCDs.

LCDs, along with OLED displays, are manufactured in cleanrooms borrowing techniques from semiconductor manufacturing and using large sheets of glass whose size has increased over time. Several displays are manufactured at the same time, and then cut from the sheet of glass, also known as the mother glass or LCD glass substrate. The increase in size allows more displays or larger displays to be made, just like with increasing wafer sizes in semiconductor manufacturing. The glass sizes are as follows:

Until Gen 8, manufacturers would not agree on a single mother glass size and as a result, different manufacturers would use slightly different glass sizes for the same generation. Some manufacturers have adopted Gen 8.6 mother glass sheets which are only slightly larger than Gen 8.5, allowing for more 50 and 58 inch LCDs to be made per mother glass, specially 58 inch LCDs, in which case 6 can be produced on a Gen 8.6 mother glass vs only 3 on a Gen 8.5 mother glass, significantly reducing waste.AGC Inc., Corning Inc., and Nippon Electric Glass.

In 1922, Georges Friedel described the structure and properties of liquid crystals and classified them in three types (nematics, smectics and cholesterics). In 1927, Vsevolod Frederiks devised the electrically switched light valve, called the Fréedericksz transition, the essential effect of all LCD technology. In 1936, the Marconi Wireless Telegraph company patented the first practical application of the technology, "The Liquid Crystal Light Valve". In 1962, the first major English language publication Molecular Structure and Properties of Liquid Crystals was published by Dr. George W. Gray.RCA found that liquid crystals had some interesting electro-optic characteristics and he realized an electro-optical effect by generating stripe-patterns in a thin layer of liquid crystal material by the application of a voltage. This effect is based on an electro-hydrodynamic instability forming what are now called "Williams domains" inside the liquid crystal.

In the late 1960s, pioneering work on liquid crystals was undertaken by the UK"s Royal Radar Establishment at Malvern, England. The team at RRE supported ongoing work by George William Gray and his team at the University of Hull who ultimately discovered the cyanobiphenyl liquid crystals, which had correct stability and temperature properties for application in LCDs.

The idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968.dynamic scattering mode (DSM) LCD that used standard discrete MOSFETs.

On December 4, 1970, the twisted nematic field effect (TN) in liquid crystals was filed for patent by Hoffmann-LaRoche in Switzerland, (Swiss patent No. 532 261) with Wolfgang Helfrich and Martin Schadt (then working for the Central Research Laboratories) listed as inventors.Brown, Boveri & Cie, its joint venture partner at that time, which produced TN displays for wristwatches and other applications during the 1970s for the international markets including the Japanese electronics industry, which soon produced the first digital quartz wristwatches with TN-LCDs and numerous other products. James Fergason, while working with Sardari Arora and Alfred Saupe at Kent State University Liquid Crystal Institute, filed an identical patent in the United States on April 22, 1971.ILIXCO (now LXD Incorporated), produced LCDs based on the TN-effect, which soon superseded the poor-quality DSM types due to improvements of lower operating voltages and lower power consumption. Tetsuro Hama and Izuhiko Nishimura of Seiko received a US patent dated February 1971, for an electronic wristwatch incorporating a TN-LCD.

In 1972, the concept of the active-matrix thin-film transistor (TFT) liquid-crystal display panel was prototyped in the United States by T. Peter Brody"s team at Westinghouse, in Pittsburgh, Pennsylvania.Westinghouse Research Laboratories demonstrated the first thin-film-transistor liquid-crystal display (TFT LCD).high-resolution and high-quality electronic visual display devices use TFT-based active matrix displays.active-matrix liquid-crystal display (AM LCD) in 1974, and then Brody coined the term "active matrix" in 1975.

In 1972 North American Rockwell Microelectronics Corp introduced the use of DSM LCDs for calculators for marketing by Lloyds Electronics Inc, though these required an internal light source for illumination.Sharp Corporation followed with DSM LCDs for pocket-sized calculators in 1973Seiko and its first 6-digit TN-LCD quartz wristwatch, and Casio"s "Casiotron". Color LCDs based on Guest-Host interaction were invented by a team at RCA in 1968.TFT LCDs similar to the prototypes developed by a Westinghouse team in 1972 were patented in 1976 by a team at Sharp consisting of Fumiaki Funada, Masataka Matsuura, and Tomio Wada,

In 1983, researchers at Brown, Boveri & Cie (BBC) Research Center, Switzerland, invented the passive matrix-addressed LCDs. H. Amstutz et al. were listed as inventors in the corresponding patent applications filed in Switzerland on July 7, 1983, and October 28, 1983. Patents were granted in Switzerland CH 665491, Europe EP 0131216,

The first color LCD televisions were developed as handheld televisions in Japan. In 1980, Hattori Seiko"s R&D group began development on color LCD pocket televisions.Seiko Epson released the first LCD television, the Epson TV Watch, a wristwatch equipped with a small active-matrix LCD television.dot matrix TN-LCD in 1983.Citizen Watch,TFT LCD.computer monitors and LCD televisions.3LCD projection technology in the 1980s, and licensed it for use in projectors in 1988.compact, full-color LCD projector.

In 1990, under different titles, inventors conceived electro optical effects as alternatives to twisted nematic field effect LCDs (TN- and STN- LCDs). One approach was to use interdigital electrodes on one glass substrate only to produce an electric field essentially parallel to the glass substrates.Germany by Guenter Baur et al. and patented in various countries.Hitachi work out various practical details of the IPS technology to interconnect the thin-film transistor array as a matrix and to avoid undesirable stray fields in between pixels.

Hitachi also improved the viewing angle dependence further by optimizing the shape of the electrodes (Super IPS). NEC and Hitachi become early manufacturers of active-matrix addressed LCDs based on the IPS technology. This is a milestone for implementing large-screen LCDs having acceptable visual performance for flat-panel computer monitors and television screens. In 1996, Samsung developed the optical patterning technique that enables multi-domain LCD. Multi-domain and In Plane Switching subsequently remain the dominant LCD designs through 2006.South Korea and Taiwan,

In 2007 the image quality of LCD televisions surpassed the image quality of cathode-ray-tube-based (CRT) TVs.LCD TVs were projected to account 50% of the 200 million TVs to be shipped globally in 2006, according to Displaybank.Toshiba announced 2560 × 1600 pixels on a 6.1-inch (155 mm) LCD panel, suitable for use in a tablet computer,transparent and flexible, but they cannot emit light without a backlight like OLED and microLED, which are other technologies that can also be made flexible and transparent.

In 2016, Panasonic developed IPS LCDs with a contrast ratio of 1,000,000:1, rivaling OLEDs. This technology was later put into mass production as dual layer, dual panel or LMCL (Light Modulating Cell Layer) LCDs. The technology uses 2 liquid crystal layers instead of one, and may be used along with a mini-LED backlight and quantum dot sheets.

Since LCDs produce no light of their own, they require external light to produce a visible image.backlight. Active-matrix LCDs are almost always backlit.Transflective LCDs combine the features of a backlit transmissive display and a reflective display.

CCFL: The LCD panel is lit either by two cold cathode fluorescent lamps placed at opposite edges of the display or an array of parallel CCFLs behind larger displays. A diffuser (made of PMMA acrylic plastic, also known as a wave or light guide/guiding plateinverter to convert whatever DC voltage the device uses (usually 5 or 12 V) to ≈1000 V needed to light a CCFL.

EL-WLED: The LCD panel is lit by a row of white LEDs placed at one or more edges of the screen. A light diffuser (light guide plate, LGP) is then used to spread the light evenly across the whole display, similarly to edge-lit CCFL LCD backlights. The diffuser is made out of either PMMA plastic or special glass, PMMA is used in most cases because it is rugged, while special glass is used when the thickness of the LCD is of primary concern, because it doesn"t expand as much when heated or exposed to moisture, which allows LCDs to be just 5mm thick. Quantum dots may be placed on top of the diffuser as a quantum dot enhancement film (QDEF, in which case they need a layer to be protected from heat and humidity) or on the color filter of the LCD, replacing the resists that are normally used.

WLED array: The LCD panel is lit by a full array of white LEDs placed behind a diffuser behind the panel. LCDs that use this implementation will usually have the ability to dim or completely turn off the LEDs in the dark areas of the image being displayed, effectively increasing the contrast ratio of the display. The precision with which this can be done will depend on the number of dimming zones of the display. The more dimming zones, the more precise the dimming, with less obvious blooming artifacts which are visible as dark grey patches surrounded by the unlit areas of the LCD. As of 2012, this design gets most of its use from upscale, larger-screen LCD televisions.

RGB-LED array: Similar to the WLED array, except the panel is lit by a full array of RGB LEDs. While displays lit with white LEDs usually have a poorer color gamut than CCFL lit displays, panels lit with RGB LEDs have very wide color gamuts. This implementation is most popular on professional graphics editing LCDs. As of 2012, LCDs in this category usually cost more than $1000. As of 2016 the cost of this category has drastically reduced and such LCD televisions obtained same price levels as the former 28" (71 cm) CRT based categories.

Monochrome LEDs: such as red, green, yellow or blue LEDs are used in the small passive monochrome LCDs typically used in clocks, watches and small appliances.

Today, most LCD screens are being designed with an LED backlight instead of the traditional CCFL backlight, while that backlight is dynamically controlled with the video information (dynamic backlight control). The combination with the dynamic backlight control, invented by Philips researchers Douglas Stanton, Martinus Stroomer and Adrianus de Vaan, simultaneously increases the dynamic range of the display system (also marketed as HDR, high dynamic range television or FLAD, full-area local area dimming).

The LCD backlight systems are made highly efficient by applying optical films such as prismatic structure (prism sheet) to gain the light into the desired viewer directions and reflective polarizing films that recycle the polarized light that was formerly absorbed by the first polarizer of the LCD (invented by Philips researchers Adrianus de Vaan and Paulus Schaareman),

Due to the LCD layer that generates the desired high resolution images at flashing video speeds using very low power electronics in combination with LED based backlight technologies, LCD technology has become the dominant display technology for products such as televisions, desktop monitors, notebooks, tablets, smartphones and mobile phones. Although competing OLED technology is pushed to the market, such OLED displays do not feature the HDR capabilities like LCDs in combination with 2D LED backlight technologies have, reason why the annual market of such LCD-based products is still growing faster (in volume) than OLED-based products while the efficiency of LCDs (and products like portable computers, mobile phones and televisions) may even be further improved by preventing the light to be absorbed in the colour filters of the LCD.

A standard television receiver screen, a modern LCD panel, has over six million pixels, and they are all individually powered by a wire network embedded in the screen. The fine wires, or pathways, form a grid with vertical wires across the whole screen on one side of the screen and horizontal wires across the whole screen on the other side of the screen. To this grid each pixel has a positive connection on one side and a negative connection on the other side. So the total amount of wires needed for a 1080p display is 3 x 1920 going vertically and 1080 going horizontally for a total of 6840 wires horizontally and vertically. That"s three for red, green and blue and 1920 columns of pixels for each color for a total of 5760 wires going vertically and 1080 rows of wires going horizontally. For a panel that is 28.8 inches (73 centimeters) wide, that means a wire density of 200 wires per inch along the horizontal edge.

The LCD panel is powered by LCD drivers that are carefully matched up with the edge of the LCD panel at the factory level. The drivers may be installed using several methods, the most common of which are COG (Chip-On-Glass) and TAB (Tape-automated bonding) These same principles apply also for smartphone screens that are much smaller than TV screens.anisotropic conductive film or, for lower densities, elastomeric connectors.

Monochrome and later color passive-matrix LCDs were standard in most early laptops (although a few used plasma displaysGame Boyactive-matrix became standard on all laptops. The commercially unsuccessful Macintosh Portable (released in 1989) was one of the first to use an active-matrix display (though still monochrome). Passive-matrix LCDs are still used in the 2010s for applications less demanding than laptop computers and TVs, such as inexpensive calculators. In particular, these are used on portable devices where less information content needs to be displayed, lowest power consumption (no backlight) and low cost are desired or readability in direct sunlight is needed.

A comparison between a blank passive-matrix display (top) and a blank active-matrix display (bottom). A passive-matrix display can be identified when the blank background is more grey in appearance than the crisper active-matrix display, fog appears on all edges of the screen, and while pictures appear to be fading on the screen.<
