do lcd displays update pixel by pixel for sale

Many Apple products use liquid crystal displays (LCD). LCD technology uses rows and columns of addressable points (pixels) that render text and images on the screen. Each pixel has three separate subpixels—red, green and blue—that allow an image to render in full color. Each subpixel has a corresponding transistor responsible for turning that subpixel on and off.

Depending on the display size, there can be thousands or millions of subpixels on the LCD panel. For example, the LCD panel used in the iMac (Retina 5K, 27-inch, 2019) has a display resolution of 5120 x 2880, which means there are over 14.7 million pixels. Each pixel is made up of a red, a green, and a blue subpixel, resulting in over 44 million individual picture elements on the 27-inch display. Occasionally, a transistor may not work perfectly, which results in the affected subpixel remaining off (dark) or on (bright). With the millions of subpixels on a display, it is possible to have a low number of such transistors on an LCD. In some cases a small piece of dust or other foreign material may appear to be a pixel anomaly. Apple strives to use the highest quality LCD panels in its products, however pixel anomalies can occur in a small percentage of panels.

In many cases pixel anomalies are caused by a piece of foreign material that is trapped somewhere in the display or on the front surface of the glass panel. Foreign material is typically irregular in shape and is usually most noticeable when viewed against a white background. Foreign material that is on the front surface of the glass panel can be easily removed using a lint free cloth. Foreign material that is trapped within the screen must be removed by an Apple Authorized Service Provider or Apple Retail Store.

If you are concerned about pixel anomalies on your display, take your Apple product in for closer examination at an Apple Store, Apple Authorized Service Provider, or an Independent Repair Provider. There may be a charge for the evaluation. Genuine Apple parts are also available for out-of-warranty repairs through Self Service Repair.*

This is my second pixel 4 xl, first one was dead straight out of the box. This one I"ve had since No… 0 Updates 7 Recommended Answers 1087 Replies 3623 Upvotes

Conventional LCD screens offer bright, glossy images but consume too much power. The images they display are also not visible in sunlight. It"s one of the reasons electronic paper, a low-power black-and-white display that can be seen clearly outdoors during the day, has become a rage among e-book readers. Pixel Qi promises to bridge both worlds.

Pixel Qi’s 3Qi display operates in three modes: a full-color LCD transmissive mode; a low-power, sunlight-readable, reflective e-paper mode; and a transflective mode, which makes the LCD display visible in sunlight.

The company is currently producing displays in the 10-inch screen size. They will debut on netbooks. Last year, research firm ABI expected 35 million netbooks to be shipped. That makes it easier to predict demand for these devices and produce displays in large volumes for them, Jepsen says. By the end of the year, Pixel Qi"s screens are expected to be in e-readers and tablets.

An image on the display is composed of millions of individual pixels. Each pixel is divided into three sub-pixels: red, green and blue. Controlling the intensity of light available to each of these sub-pixels helps produce a color image.

Now, each of the subpixels are further divided into transmissive and reflective modes. In transmissive mode, the screen is primarily lit from the rear using a backlight. When the light reaches the LCD panel, it passes through polarizers that allow it to light up the required combination of subpixels.

The resultant reflected light is picked up by the eye. Pixel Qi"s full-color 10-inch screen has a resolution of 1024 by 600 pixels. It almost feels like a conventional LCD display though the colors aren"t as saturated and the image isn"t as vivid.

At its peak, the Pixel Qi"s display consumes far less power than conventional LCDs. Peak power is 2.5 watts. Turn off the backlight and you can shave 2 watts off, giving you an extremely low-power display.

In the reflective mode, the backlight is turned off and the ambient light hits a layer of mirror on the display that reflects it back completely. The result is a much higher resolution than in the LCD mode and a screen that plays just off the grayscale rather than creating colors.

The Pixel 5 isn"t quite worth its high price, especially since its software support window ends soon (October 2023). Amazon currently sells the Pixel 4A 5G for the same price as the Pixel 6A, and while it"s a good phone, it should be cheaper. You"re better off sticking with the Pixel 6A. As for older Pixels, they"re not worth picking up. They"re just too old (and the Pixel 4 suffers from poor battery performance). Many of those devices will stop getting software updates soon if they haven"t already. Buy one of the newer models.

The revamped case for the Pixel 7 series feels more durable than ever before, and you can match them with your Pixel"s color. The thermoplastic elastomer feels nice to touch, and there are raised edges on the front to protect the screen. The Pixel 7"s case is made with more than 30 percent recycled plastics, and the polycarbonate shell uses 77 percent recycled plastics. There are metal buttons for power and volume and they"re 100 percent recycled aluminum. The cases for the Pixel 6 and Pixel 6A are similar but slightly different.

This is hands-down the best case if you frequently attach your Pixel to the handlebar of a bike or electric scooter. Peak Design"s mounting system lets you magnetically affix the phone to its Universal Bike Mount ($50) and it stays put—after nearly a year of testing, I"ve yet to have a phone fall off my ride using this mounting system. It doesn"t interrupt the Pixel"s wireless charging either. The company has several other magnetic accessories you can use, like a car mount. The case itself is nice; I just wish the edges were raised a bit more for better screen protection.

This is one of the best clear cases you"ll find, especially at this price, for the Pixel. The buttons are clicky, the Pixel"s color comes through clearly, and the rear doesn"t feel too sticky, which can be a problem with some clear cases.Caseology Tempered Glass Screen ProtectorPhotograph: Caseology

Pixel phones don"t have a great track record with screen durability—they scratch easily. We tested this protector originally for the Pixel 5A, but it"s not available anymore. Caseology does sell it now for the Pixel 7, Pixel 6, and Pixel 6A. Installation is easy, and it includes a squeegee to get rid of air bubbles. You get two screen protectors for the price, including a microfiber cloth, a wipe, and dust removal stickers.

This is another easy-to-apply tempered glass screen protector. The Pixel 7 and Pixel 6 version comes with two protectors, but Spigen only includes one for the Pixel 6A. Boo. You get a whole cleaning kit to wipe down your phone, an alignment tool that helps you get the application right, and a squeegee to get rid of the air bubbles.

You get only one screen protector here and it"s very expensive. That"s because Zagg claims that the protector is five times as strong as traditional screen protectors. I haven"t seen too many scuffs on my Pixel 6A yet, but take this with a grain of salt. It"s easy to apply with the included application tool, but Zagg doesn"t include a squeegee at this price so you"ll have to use your fingers to push the air bubbles out. It comes with a dust sticker, a wet wipe, and a microfiber cloth.Google Pixel Stand (Gen 2)Photograph: Google

Of the Pixels we recommend in this guide, wireless charging is available only on the Pixel 6, Pixel 6 Pro, Pixel 7, and Pixel 7 Pro. Google"s very own Pixel Stand is one of the best wireless chargers around because it"s simple. The base doesn"t slide around, the phone stays put, and it enables some fun features, like turning the screen into a digital photo frame and quick access to Google Assistant. It"s made of 39 percent recycled materials, with mostly eco-friendly packaging too. Our Best Wireless Chargers guide has more options. It"s also available at Best Buy.

This charging adapter is all you need to recharge your Pixel, whichever model you have. The newest high-end Pixel phones don"t come with chargers in the box, so if you don"t have any spare USB-C chargers, it"s worth picking one up. This one"s prongs don"t fold up, but it"s still really compact.

These cases are pricey, but they have raised lips and offer decent protection around the edges. The buttons are clicky, and you get a few designs to choose from for the rear, including walnut, leather, bamboo, silver pearl, and aramid fiber. (I love the walnut.) What makes this case special is that it supports MagSafe—yes, Apple"s magnetic system for accessories. I"ve used the Mous Limitless 5.0 successfully with a few MagSafe accessories, like a Belkin wireless charger, to recharge the Pixel 7 Pro. You can also go with Mous" IntraLock case to use the company"s own magnetic accessory system to hook your phone up to its bike or car mount with more security.Photograph: Spigen

It"s slim, has a nice texture, retains clicky buttons, and has accurate cutouts for the ports and speakers. What"s not to love? Well, it"s a bit dull, but I still think this case is one of the more attractive cases in Spigen"s lineup. The edges aren"t raised drastically, so don"t expect much screen protection.

Want a kickstand to prop your Pixel up? This Spigen case has one built in and it does the trick, though unfortunately, you can keep your device up only in landscape mode—not great for hands-free TikTok. It has a thick bumper offering nice protection around the edges, though there"s not much of a lip sticking out, so you"ll still want to pair it with a screen protector.

Of all the Pixel cases I"ve tried, this feels the best. It has a wonderful texture that"s pleasant to touch, and the case keeps a slim profile. The buttons remain clicky, and the ports are well-exposed. It"s affordable, but the front edges aren"t raised. There"s a good chance the screen will hit the ground when you drop it.Photograph: Moment

The Pixels have great cameras, but you can take them further by using third-party lenses like these from Moment. Slap on a fish-eye lens for a fun, distorted photo effect. Use a 58-mm telephoto to get even closer to your subject. Whatever lens you pick, you"ll need a Moment case for the system to work. Unfortunately, the Pixel 7, Pixel 7 Pro, and Pixel 6A cases aren"t compatible with the lenses. Still, I like "em because they have magnets embedded inside—they"ll work with Moment"s various MagSafe mounts, like one for tripods, video lights, and mics.

It takes some effort to install this case on the Pixel, but once you do, it"s arguably the most protection you"ll find. There"s an inner two-piece polycarbonate shell that snaps over and under the Pixel, and then a thick synthetic rubber slipcover goes over for extreme durability. The buttons are surprisingly clicky, though the whole phone will be thicker, wider, and heavier. It"s made of more than 50 percent recycled plastic, and there"s a holster you can pop it in to carry your Pixel with pride on your belt. (The holster can double as a kickstand.)

There are some key features exclusive to Pixels that you won"t find on any other Android phone. Some of these are only available on select Pixels—the ones powered by Google"s Tensor chips are more capable since it"s the company"s own silicon. Here"s a quick breakdown:

If you spend long enough debating the merits of LCD vs. OLED display technologies, eventually, someone will touch upon the subject of the dreaded OLED screen burn in. The point made is that OLED displays will inevitably suffer from horrible-looking artifacts over time, while LCD and new technologies like Mini-LED won’t. But like most of these debates, you’ll probably hear as many overblown anecdotes as you will actual facts about the issue.

You may never have experienced it for yourself, but many consumers are wary about the possibility of burn in when pondering their next smartphone purchase. Particularly as expensive flagship smartphones have universally adopted OLED display technology. Apple, Google, and other manufacturers acknowledge that burn in can be a problem in rare cases. OLED technology has made its way to much more affordable price points in recent years, putting the issue on the radar for even more consumers.

The word “burn in” is a little misleading, as no actual burning or heat problems are involved. Instead, this term describes a display suffering from permanent discoloration across any part of the panel. This may take the form of a text or image outline, fading of colors, or other noticeable patches and patterns on display. The display still works as expected, but a somewhat noticeable ghost image or discoloration persists when the screen is on. To be considered screen burn in, these artifacts have to be permanent and are a defect caused on the display hardware side. Rather than a graphical glitch that may be caused by software, temporary image retention, or a problem with the display driver circuitry.

The term dates back to old CRT monitors, where phosphor compounds that emit light to produce images lost their luminance with time. LCD panels can exhibit similar problems, but these are much rarer due to the nature of LCD’s backlight and color matrix design.

Although not as bad or noticeable as old CRT issues, today’s OLED smartphone displays can eventually suffer from a similar problem. That being said, it’s pretty difficult and rare to notice unless you know what you’re looking for, and it takes hundreds, if not thousands, of hours of screen-on time before any such errors appear. In smartphones, pattern burn in is typically associated with always-on displays, navigation buttons, and the notification bar. The example below demonstrates a textbook case:

The cause of all screen burn in is the varying lifecycle of a display’s light-producing components. As these parts age, their brightness changes, and therefore the panel’s color reproduction gradually shifts with time. Although this can be mitigated somewhat with clever software, all displays experience some color shift as they age. But with burn in, some parts of the screen age faster than others. This can gradually shift the perceivable colors of the screen in one area more than in another, leaving what looks like a ghost image behind.

With modern smartphone and smartwatch technology, screen burn in can manifest due to the different life spans between the red, green, and blue LED subpixels used in OLED panels. As we mentioned before, areas of the display that seldom change, are bright white, or are often black and switched off, such as navigation buttons or the notification bar, are the most likely areas to notice this issue. You may also notice the effect in darkened status bars designed to hide display notches.

This is because these areas are more likely to consistently display one color, a set icon, or text. In contrast, the rest of the display produces a more random selection of colors from various websites, videos, apps, etc., over a long period of use. Therefore the subpixels in these areas see different amounts of use and thus age differently, eventually resulting in a slight variation in color reproduction. Switching to transparent and color-changing bars has the added bonus of evening out the color aging process.

Speaking more technically, the issue is that blue LEDs have significantly lower luminous efficiency than red or green pixels. This means that a blue LED needs to be driven at a higher current for a set sized pixel to achieve the same brightness as red or green. Higher current causes the pixel to degrade faster, shortening its lifespan and eventually tinting the display towards the red and green colors. Therefore an OLED display’s color doesn’t degrade evenly; it will ultimately lean towards a red/green tint.

So, if one part of the panel spends a lot of time displaying a blue or white image, the blue pixels in this area will degrade faster than in other areas. That’s essentially what burn in is. However, display manufacturers do account for this in their panel designs.

If OLED screens have a problem with burn in, why do we continue using them? Burn in is a true downside to OLED displays, but there are plenty of reasons consumers and manufacturers like them. For starters, image quality is much better than in LCDs. OLED panels can reproduce more vibrant colors, more contrast, wider viewing angles, and faster refresh rates. Colors tend to be much more saturated, and blacks are much darker.

OLED displays have a simpler design, allowing thinner, lighter smartphone designs. You can also thank OLED technology for foldable phones and curved displays. If those improvements weren’t enough, you’ll also enjoy lower power consumption with OLED.

Additionally, burn in problems are only common after prolonged periods of use. As you may already know, smartphone manufacturers don’t expect you to keep a smartphone for more than 2-3 years. Recent statistics show that consumers currently keep their phones for an average of 2.75 years.

At this stage, manufacturers are very aware of the potential issues and have already taken some intelligent steps to help avoid burn in. For starters, Samsung has been using its pentile subpixel arrangement in its AMOLED displays since the Galaxy S3. By making the blue subpixel larger, it requires less current to drive in order to provide the necessary light. Driving the LED with less current increases its lifespan, so it takes longer for any noticeable color shift to occur.

This doesn’t directly address the issue of different parts of the screen aging at different rates, but it does mean that it will take significantly longer to notice than with older or cheaper OLED panels. More expensive and modern OLED panels are built with longer-lasting LEDs and well-designed layouts, meaning flagship smartphone displays age slower. These days, it’s cheaper phones packing cheaper displays that are marginally more likely to see issues after heavy use.

There are software solutions too. Android Wear product manufacturers can enable the OS’s “burn protection” option. This mode periodically shifts the screen’s contents by a few pixels, so they spend equal time displaying different colors. Smartphones equipped with Always-On display technology employ a similar tactic. Google also suggests a selection of design guidelines tailored to avoid screen burn-in problems when designing OLED watches. The move towards gesture rather than on-screen navigation controls is also helping to alleviate one of the more noticeable burn in areas.

If your screen is already burnt in, there’s not much that can be done to undo the damage. Some apps on the Play Store claim to reverse the problem. These will end up “burning” the rest of the screen to match the colors, which isn’t a real solution.

Keep your display brightness as low as reasonable. Increased brightness requires more current and therefore shortens LED lifespans. Don’t crank up the brightness unless you have to.

All that said, screen burn in isn’t something that should concern many users if they’re looking to buy a new OLED smartphone. Modern panels have much longer lifespans than early OLED smartphones, and even then, burn in was rare. Just don’t leave a static image on the screen 24/7 with the brightness set at max.

The bottom line is that you should be looking at several years’ worth of use out of a modern smartphone display before any screen burn in will be noticeable. But it doesn’t hurt to be aware of what can happen to aging handsets and how to maximize their lifespan.

Google offers at least three years of software and security updates, and certain older models even include unlimited cloud storage for pictures using Google Photos" Storage Saver quality. That last benefit isn"t offered on the Pixel 7 and 7 Pro, giving anyone with an older Pixel a lot to consider before upgrading.

To help you decide, we"ve compared the Pixel 7 and 7 Pro against each previous Pixel phone. We"ve also taken any perks you might lose from upgrading into consideration, like the previously mentioned unlimited cloud storage.

Google"s latest flagship phones are now available to buy. The Pixel 7 starts at $599. Get up to $750 off with trade-in and $200 in Google Store credit.

The Pixel 7 and 7 Pro have a slightly upgraded design, the new Tensor G2 processor and camera improvements. A free VPN service will eventually come to the Pixel 7 and 7 Pro, too. Both phones run Android 13 and also support face unlock. But if you already have a

The Pixel 7"s upgrades are appreciated but incremental. Unless you can get a new Pixel for free through a trade-in program, the differences aren"t drastic enough to justify spending money for a year-over-year upgrade.

The Pixel 6 family runs on the first-generation Tensor processor, which is still fast enough for most everyday tasks. Google also issued software updates to fix certain bugs some users experienced with the fingerprint sensor and screen earlier this year.

The 7 and 7 Pro"s screen sizes are almost exactly the same as on last year"s devices, except the Pixel 7"s 6.3-inch display is slightly smaller than the 6.4-inch one on the Pixel 6. Both the Pixel 7 Pro and

The biggest camera change you get with the Pixel 7 Pro is an improved zoom that is longer and has better image quality. Google made some behind-the-scenes improvements to the way the image sensor crops the scene when zooming. The Pixel 7 Pro also fuses data from the main and telephoto lenses when zooming between 2.5x and 5x for better clarity.

Both phones get a longer digital zoom range of 8x for the regular Pixel 7 and 30x for the 7 Pro that let you frame your subject tighter. Compare that to the 7x and 20x magnifications for the Pixel 6 and 6 Pro respectively.

Both new phones also have a tool called Photo Unblur for sharpening older photos, even pictures taken with other phones and cameras. Photo Unblur is exclusive to the Pixel 7 and 7 Pro since it requires the new G2 processor and builds off the Pixel 6 and 6 Pro"s Face Unblur tool.

These are commendable improvements, but they aren"t significant enough to justify an upgrade. That"s especially true since Google upgrades older phones with new features over time. The Pixel 6 and 6 Pro, for example, will get new features such as Clear Calling, Guided Frame (the feature that provides auditory and haptic cues to help those who are blind or low vision take selfies) and the ability to transcribe audio messages.

The Pixel 5 falls into a sort of middle ground that makes the question of whether it"s time to upgrade a difficult one to answer. The Pixel 7"s changes are dramatic enough to make a noticeable difference, particularly when it comes to the design and camera. But the Pixel 5 is also new enough to feel fast and relevant for at least another year or two.

As is typically the case with today"s new smartphones, the Pixel 7"s biggest upgrades can be found in the camera. The Pixel 7 and 7 Pro each have a higher-resolution 50-megapixel main sensor compared to the 12.2-megapixel main sensors found on the Pixel 5 and

If you"re upgrading from the standard 6.1-inch Pixel 5, you"ll also get a larger screen whether you choose the 6.3-inch Pixel 7 or 6.7-inch Pixel 7 Pro. The Pixel 5A, however, is the same size as the Pixel 7.

There are several other smaller changes that come together to make the Pixel 7 generation feel new and different. The Pixel 7 and 7 Pro have a refreshed design with more durable Gorilla Glass Victus back panels and metal camera bars stretching across the device. Overall the 7 and 7 Pro feel more premium than the Pixel 5 and 5A. The new phones also have an in-screen fingerprint reader compared to the rear-mounted one on the Pixel 5.

But the best time to upgrade is when you feel like you need it. If your Pixel 5 or 5A is in good condition, you won"t miss out on anything critical by holding onto your device for a while longer. Google supports the Pixel 5 with new Android software versions and security updates until at least October 2023, while the Pixel 5A will get the same support through August 2024. The Pixel 5 is also the last Pixel phone to get unlimited cloud storage for pictures at the Storage Saver quality, but the Pixel 5A does not have this benefit.

The Pixel 7 and Pixel 7 Pro arrive just as the Android 13 will be the final major software update planned for the phones. And there"s no guarantee that Google will continue to provide security updates to either device, which could mean that the phones become vulnerable to exploits as time goes on.

That"s not all bad, as you do get Android 13 features like the Material You interface, the redesigned music player, improved continuity such as copying and pasting content between devices and additional security features like automatically deleting your phone"s clipboard history. The Pixel 4 and 4 XL also both retain Google"s unlimited cloud storage for photos and videos benefit, as long as that media is uploaded in Storage Saver quality.

Upgrading from the Pixel 4 series -- which run on the Qualcomm Snapdragon 855 processor -- to Pixel 7 series" Tensor G2 chip brings a wealth of AI-powered photography enhancements like Photo Unblur and Real Tone. The Pixel 4A and 4A 5G with their less powerful Snapdragon 730G and 765G chips, respectively, also pale in comparison to the new Tensor G2 chip.

Other than losing the photo storage benefit, upgrading from the 4 and 4 XL also means you say goodbye to the phones" Motion Sense features. At the time, the 4 and 4 XL touted a sensor chip named Soli, which allowed for facial recognition similar to Apple"s Face ID along with other gestures meant for controlling the phone. The features proved unpopular though, and largely disappeared from later Pixel phones. The Pixel 7 does introduce Face Unlock, but it"s not as secure as Apple"s Face ID nor what was previously used on the Pixel 4 series.

The bottom line: If you have the Pixel 4 and 4 XL, the end of software and security updates means it"s a great time to upgrade to the Pixel 7 or 7 Pro. You"ll see big improvements to the phone"s power, camera performance and software. If you aren"t ready to give up Pixel 4 exclusives like Motion Sense or the unlimited cloud storage, hold onto your phone a bit longer.

If you are still holding onto the 9to5Google. All four of the Pixel 3 phones can run Android 12, but won"t be receiving Android 13. While the phones do retain the benefit of unlimited cloud storage for photos and videos uploaded at Storage Saver quality, the phones could become vulnerable to exploits or similar issues.

One interesting note for those still holding onto the original posted on Reddit, which appears to serve the purpose of transferring photos over to the Pixel for uploading. CNET hasn"t verified nor endorses the method -- again, the phone no longer receives security updates. But if you have the phone on hand and it still turns on, it could be a fun experiment for occasional use.

The bottom line: The Pixel 3 series will no longer receive software or security updates, making the phones a potential liability moving forward. While the phones are running Android 12 and will continue to otherwise function, it"s best to move onto a newer phone as soon as you can.

The Google Pixel and Pixel XL were released in late 2016 with the camera experience being the central focus of marketing for this Android smartphone launched by Google. The camera experience is central to the Pixel phones, largely due to the advanced software and algorithms and not directly related to having the best camera hardware.

In addition to imaging performance, Google Pixel phones are similar to the Apple iPhone with regular software updates and Android security updates. Nearly every software update brings enhancements, new features, and performance improvements. Unlike some other Android phones, you can rest assured that your Pixel phone will be supported for at least five years too.

Google is also following in Apple"s footsteps in establishing an ecosystem of connected products. With fantastic Chromebooks, new watches, and the release of the Pixel 7 series phones, Google offers compelling alternatives to Apple and Samsung.

With top-of-the-line camera features, long-lasting batteries, and a sleek redesign, see why some of the best Pixel phones are worthy options to consider. Furthermore, broaden your search by checking out our page on the best Android phone where we compile extensive research.

The Pixel 7 Pro features a fresh design with some exceptional camera improvements. New is the metal wraparound camera bar, whereas, in previous models, the camera bar stopped at the edge of the phone. Differentiating the 7 Pro further is the extra cutout for the phone"s third camera.

Speaking of the camera…my goodness, Google upped its game. The new 30x Super Res Zoom allows you to snap vivid details from a distance. You"ll also enjoy the fine attention to smaller details thanks to Macro Focus–only found on the Pixel 7 Pro. And, for aspiring filmmakers, the Cinematic Blur allows you to focus on the foreground or background objects while blurring out the rest to maximize impact.

In the past, Google offered two variants with one being considerably smaller than the other. This year, the size difference is minor, but there are some differences to consider. The Pixel 6 does not have the third telephoto camera on the back, it has a flat display rather than a curved one (this is a benefit IMHO), it has less RAM, and it has a smaller capacity battery. However, it also starts at a price $300 less than the Pixel 6 Pro.

Camera performance has always been a pillar of the Pixel experience and Google delivers yet again with the Pixel 6 and its unique and distinct camera bar that sits proudly near the top of the back of the phone. There is plenty of RAM to keep things running quickly on the Pixel 6 while the latest Android software is optimized for the Pixel phone experience.

There are some unique Google experiences contained in the Pixel 6 that are not found in Android smartphones from Samsung, OnePlus, TCL, and others. These include the Magic Eraser tool that helps you quickly remove unwanted subjects from your photos, Google Assistant calling features, and the core Material You customization options.

The Pixel 5a with 5G may appear to be a rather boring phone with an unassuming design harkening back to the Pixel 4a, but it offers a lot of power in a package priced at just under $450. There are also often sales on the phone, bringing it down to less than $400.

It comes in one color, but the black looks like a very dark green in most lighting conditions, and in one RAM/storage configuration. While the specifications are not as high-end as a flagship phone priced at two times the cost, the power of the Pixel 5a with 5G is in the Google software experience. It is powered by the latest version of Android and continues to receive regular updates along with Google"s flagship Pixel phones.

Camera performance and results also continue to be a staple of the Pixel phones here with outstanding results. Given the mid-level processor and lower resolution display, the phone also lasts a long time on the high-capacity battery so you can use it for one or two days in most situations.

The Pixel 7 does many things well. It literally has battery life for days. Use its Extreme Battery Saver to get up to 72 hours of use on a full charge. And its Adaptive Battery lasts over 24 hours, giving you more time to enjoy the phone"s abundant features.

Further, if you"re an avid photographer or videographer, the new camera features are fantastic. The front camera features a 92.8° ultrawide view, giving you space to wiggle more people or scenery into your shot. Should you need to touch up photos, the Pixel 7 has Photo Unblur and Magic Eraser to sharpen pictures and remove distractions. The phone also has Cinematic Blur, allowing you to bring the subjects you want into focus, while blurring out the rest for a dramatic impact that fish hooks eyes.

Speaking of visually appealing, the phone"s sleek redesign enhances its appeal and its durability. Google constructed the phone from 100% recycled aluminum, giving it a durable, yet lightweight grip. Ultimately, this phone shows you don"t have to spend handfuls of Benjamins to receive flagship features.

The Google Pixel 7 Pro elevates photography. Along with the ample photo and video editing features the phone contains, it"s also sleek, lightweight, and has enough battery life for 24 hours of use. All told, it"s one of the most dynamic phones on the market.

If you are interested in a Google Pixel phone, it"s nice to know there are not many options available to confuse you or overwhelm your decision-making process. The first consideration is price and if you have a maximum amount you are willing to spend on a phone then the price dictates which is right for you.

Thankfully, when it comes to the software experience Google provides the same experience across all of the actively supported Pixel phones.Choose this Google Pixel phoneIf you want...

This article only includes Google Pixel phones that are actively sold by Google on the Google Store. There are older model Pixel phones that continue to receive software and firmware updates, but these are only available as used or refurbished phones from retailers such as Amazon and some wireless carriers.

Display refresh rates are a consideration today since Android phones now support refresh rates up to 120 Hz. Displays with high refresh rates, the default is 60 Hz, allow you to scroll up and down the display faster with smoother performance. It is primarily noticeable when you swipe up and down side-by-side with devices that have different rates, but once you use a phone with 120 Hz refresh rate, it is tough to go backwards.

The Pixel 7 Pro supports a refresh rate up to 90 Hz, the Pixel 6 up to 90 Hz, and both the Pixel 5a and 6a remain at the default 60 Hz rate. 90 Hz is a decent compromise between the two.

People use their smartphones everywhere today and having some level of dust and water resistance is important. You should not swim or intentionally submerge your phone for extended periods in water without a waterproof case and warranties generally do not cover water damage. However, if you are outside in the rain, accidentally drop your phone in a puddle, or spill something on your phone it should be able to survive such an incident.

Thankfully, all of the current Pixel phones have a fairly high level of dust and water resistance. The Pixel 5a and 6a are both certified for IP67 while the Pixel 7 and Pixel 7 Pro are rated for IP68.

You may experience a stuck pixel on a new or used LCD screen. If your monitor’s warranty has expired, or the manufacturer won’t replace the monitor because it considers one or two stuck pixels as acceptable, there are a few things that you can do.

This is obviously the safest method, but it’s not always effective. If you recently discovered a stuck pixel, you can try to turn off the monitor and unplug it for a day or two. When the damage is caused by overuse, this could help.

There are many websites that offer a stuck pixel fixing service. They work more or less in the same way, by flashing pixels and hopefully un-stick the ones that are defective.

You’ll find that many of them run with Flash, which is no longer available – fortunately, here’s one that you can still rely on – JScreenFix. JScreenFix is a free online service that can solve your problem of stuck pixels. You don’t have to download anything, so it’s not invasive nor harmful.

Visit the website jscreenfix.com and scroll down to find the Launch JScreenFix button – click on it. It will open a black screen with a square full of flickering pixels. The instructions pop up right there – however, what you’re meant to do is drag this square to the area where the stuck pixel is. Then, leave it for at least ten minutes.

If it doesn’t fix your stuck pixel on the first try, you can do a few attempts leaving it for a little longer. Usually, this method gets the job done, but it’s not a 100% guarantee.

*Safety note: If you have epilepsy, you should avoid using any of these stuck pixel fixer websites or software as they work with flashing erratic lights.

Any technique that implies applying pressure to fix a stuck pixel can potentially make more damage than good. Here you’ll find some precautions you should take to minimize these chances.

However, if you decide to do this, it’s at your own risk. Turn on your computer screen or monitor as the pixel needs to be working for the pressure methods to stand a chance.

Determine if you have hot, stuck or dead pixels – if you don’t know the difference among these, read the next section first. Only if the pixel is stuck, you’ll have a chance at fixing it with a pressure method.

Open a black image as background in full-screen mode or use a black browser window such as this. Either way, don’t just leave a blank signal. This again has to do with the fact that you need the pixel to have the backlight on. Make sure the screen is clean to avoid confusing dust with bad pixels.

Some people recommend a heat method where you use a hairdryer to warm the spot while you’re putting pressure on the monitor to fix a stuck pixel. Others suggest using a hot water damp cloth to apply the heat directly.

However, you could end up with something worse than a stuck pixel. The pressure method already represents a small risk of damaging your monitor – if you add heat, you’re increasing that risk.

To understand the possible pixel problems that you can face – and whether or not you can fix them – you need to know that an LCD screen is made by pixels. Three sub-pixels form each pixel – one is red, one is green, and one is blue (RGB).

When you have a pixel defect, it means that one or more of the subpixels aren’t working as they’re supposed to. Let’s see how these can present. Dead pixels

Dead pixels show no light, and what’s the absence of light? Dark. So, if you see a black pixel on your monitor, it’s a dead pixel. These are more noticeable when you’re working with a white background. Stuck pixels

The third option is that you see a white pixel – these are known as hot pixels. That means that all three colors (red, green and blue) are always on – this results in white light. These are more obvious on a dark background.

So, now you know what type of faulty pixels you can run into and how you can identify them. At this point, you might be wondering how do stuck pixels happen?

LCD stands for liquid crystal display. These monitors are made with multiple layers. In the far back, they have the light source that illuminates the screen with white even light.

The reason why we don’t see a fully white screen all the time is that there’s also a layer with color filters. This layer has a red, green and blue filter per pixel (RGB) – each of those would be a sub-pixel.

They can do this according to the amount of voltage. No voltage means that light can pass – full voltage blocks the light. Everything in between allows a different amount of light to pass through.

Anyway, all this explanation is to tell you that stuck or dead pixels often happen because there is a broken transistor that fails to supply voltage to a certain pixel or sub-pixel. Keep in mind that there are two types of LCD monitors: TN (Twisted Nematic) and IPS (In-Plane Switching). On TN monitors, the default without voltage is on. So, if the transistor is not supplying power, the pixel won’t be dead (black) but hot (white). On IPS monitors, it works the other way around.

So, you can use a dead pixel test. There are some free ones online such as the one from LCD Tech. You simply need to click on the Start Test button, and it will automatically enter full-screen mode in complete white.

Make sure your monitor is clean to identify dead pixels better. Because the screen will be completely white, you can also use this to find stuck pixels. On the other hand, a hot pixel won’t be visible – for these, you would need a dark screen.

Sometimes you can have bad luck and receive your new computer or monitor with an original pixel fault. In most cases, these are dead pixels, and therefore, there’s nothing you can do except try and exchange your monitor with the manufacturer.

Keep in mind that these are just good practices that can extend the life of your LCD screen. Unfortunately, there isn’t a full-proof method to avoid getting stuck pixels.

Stuck pixels are the most fixable problems you can have with your pixels. A stuck pixel can disappear on its own, or you can use other methods to try to fix it – in this article, you’ll find some of them.

It depends on the class of monitor that you have – only class I monitors shouldn’t have any dead pixels. For other classes, most manufacturers will consider one dead pixel as acceptable. This means that they probably won’t replace your new monitor because of it.

Of course, if this acceptable to you, it’s a different matter. It often depends on the location of the dead pixel and the size of the monitor. If you find it unacceptable, you should still give it a shot at the guarantee and see if you can have it exchanged. Check the ISO 13406-2 to see the ‘acceptable’ standards according to the type of monitor.

No, dead pixels won’t go away on their own – most of the times, they’re not even fixable. Before you give up, though, make sure the pixel is really dead and not stuck – because stuck pixels can go away.

Dead pixels are more noticeable in light areas because they are black. Also, it depends on the size of the pixel, the size of the display and the resolution. Keep in mind that once you know it’s there, you’ll keep noticing it.

If your warranty is valid and you can get your device exchanged, that’s the best way to do it. Otherwise, determine what type of pixel problem you have.

There are a few different methods to try to fix stuck pixels – although none of them is certain. On the other hand, hot and dead pixels can’t be fixed.

I hope you found this guide helpful. If you have any questions or want to share some tips on preventing, detecting, and fixing faulty pixels, please leave a comment.

The pixels have to be on continuously, if that was not the case (the pixel is off and dark most of the time) then they would have to be extremely bright when it is on to display an image. On a CRT this sort of happens (the dot is very bright) but the phosphors make the dot glow for some time.

Your eyes aren"t that quick to respond so if all pixels are addressed in such a short time that your eyes won"t notice it then there is no issue in addressing the pixels in a certain sequence.

Something like that indeed, but not pixel-for-pixel, instead one row (or column) is refreshed in one go. Then the next row (or colum) etc. How this precisely done depends on the actual display.

Pixel pitch describes the density of the pixels (LED clusters) on an LED display and correlates with resolution. Sometimes referred to as pitch or dot pitch, the pixel pitch is the distance in millimeters from the center of a pixel to the center of the adjacent pixel. Since pixel pitch indicates the amount of space between two pixels, a smaller pixel pitch means there is less empty space between pixels. This equates to higher pixel density and improved screen resolution.

Pixel pitch is important because it influences the optimal viewing distance for your display. An image achieves smoother borders and finer detail with lower pixel pitch values. This allows the viewer to stand closer to the screen and enjoy a clear image without the distraction of discerning individual pixels. When determining viewing distance and pixel pitch, the rule of thumb is that a smaller pixel pitch allows for a closer viewing distance. Conversely, a higher pixel pitch elongates the minimum viewing distance. So, a 1.2mm screen will have significantly higher resolution and a closer optimal viewing distance than a 16mm .

While higher pixel density delivers improved visual quality, it is not the ideal option for every situation. Additional pixel density is intended for a closer viewing distance. At a greater viewing distance, higher pixel density loses its visual advantages and simply increases the cost of the display.

Consumers can get the best value for their LED screen by determining the optimal viewing distance of their screen. The optimal viewing distance is the point where image fidelity is retained, but if the observer moved much closer, the image quality would decrease or the screen would appear pixelated.

For example, a display with interactive touch solutions will need a low pixel pitch to produce crisp images for the nearby audience. On the other hand, an LED screen displayed above viewers, like one hung in an arena, could get away with a higher pixel pitch. The short answer is that a smaller pixel pitch will always give you better quality image, but the investment will not be fully appreciated if the screen is not seen from a sufficiently close enough distance.

Visual Acuity Distance – also known as retina distance, this is a formulated calculation of the distance a person with 20/20 vision must move away from an LED screen to see a coherent image that is not pixelated.

While these methodologies are useful guides, there is no correct answer in determining viewing distance. A screen’s viewing distance is ultimately whatever the owner of the screen finds comfortable.
