tft display smartphones list free sample

In recent years, smartphone displays have developed far more acronyms than ever before with each different one featuring a different kind of technology. AMOLED, LCD, LED, IPS, TFT, PLS, LTPS, LTPO...the list continues to grow.

There are many display types used in smartphones: LCD, OLED, AMOLED, Super AMOLED, TFT, IPS and a few others that are less frequently found on smartphones nowadays, like TFT-LCD. One of the most frequently found on mid-to-high range phones now is IPS-LCD. But what do these all mean?

LCD means Liquid Crystal Display, and its name refers to the array of liquid crystals illuminated by a backlight, and their ubiquity and relatively low cost make them a popular choice for smartphones and many other devices.

LCDs also tend to perform quite well in direct sunlight, as the entire display is illuminated from behind, but does suffer from potentially less accurate colour representation than displays that don"t require a backlight.

Within smartphones, you have both TFT and IPS displays. TFT stands for Thin Film Transistor, an advanced version of LCD that uses an active matrix (like the AM in AMOLED). Active matrix means that each pixel is attached to a transistor and capacitor individually.

The main advantage of TFT is its relatively low production cost and increased contrast when compared to traditional LCDs. The disadvantage of TFT LCDs is higher energy demands than some other LCDs, less impressive viewing angles and colour reproduction. It"s for these reasons, and falling costs of alternative options, that TFTs are not commonly used in smartphones anymore.Affiliate offer

IPS technology (In-Plane Switching) solves the problem that the first generation of LCD displays experience, which adopts the TN (Twisted Nematic) technique: where colour distortion occurs when you view the display from the side - an effect that continues to crop up on cheaper smartphones and tablets.

The PLS (Plane to Line Switching) standard uses an acronym that is very similar to that of IPS, and is it any wonder that its basic operation is also similar in nature? The technology, developed by Samsung Display, has the same characteristics as IPS displays - good colour reproduction and viewing angles, but a lower contrast level compared to OLED and LCD/VA displays.

According to Samsung Display, PLS panels have a lower production cost, higher brightness rates, and even superior viewing angles when compared to their rival, LG Display"s IPS panels. Ultimately, whether a PLS or IPS panel is used, it boils down to the choice of the component supplier.

This is a very common question after "LED" TVs were launched, with the short answer simply being LCD. The technology used in a LED display is liquid crystal, the difference being LEDs generating the backlight.

Despite the improvement in terms of contrast (and potentially brightness) over traditional LCD/LED displays, LCD/mini-LEDs still divide the screen into brightness zones — over 2,500 in the case of the iPad and 2021 "QNED" TVs from LG — compared to dozens or hundreds of zones in previous-generation FALD (full-array local dimming) displays, on which the LEDs are behind the LCD panel instead of the edges.

However, for even greater contrast control, done individually at each point on the screen, it is necessary to go to panels equipped with microLED technologies – still cost-prohibitive in 2021 – or OLED, which until recently were manufactured on a large scale only in sizes for smartphones or televisions.Affiliate offer

AMOLED stands for Active Matrix Organic Light-Emitting Diode. While this may sound complicated it actually isn"t. We already encountered the active matrix in TFT LCD technology, and OLED is simply a term for another thin-film display technology.

OLED is an organic material that, as the name implies, emits light when a current is passed through it. As opposed to LCD panels, which are back-lit, OLED displays are "always off" unless the individual pixels are electrified.

This means that OLED displays have much purer blacks and consume less energy when black or darker colours are displayed on-screen. However, lighter-coloured themes on AMOLED screens use considerably more power than an LCD using the same theme. OLED screens are also more expensive to produce than LCDs.

Because the black pixels are "off" in an OLED display, the contrast ratios are also higher compared to LCD screens. AMOLED displays have a very fast refresh rate too, but on the downside are not quite as visible in direct sunlight as backlit LCDs. Screen burn-in and diode degradation (because they are organic) are other factors to consider.Affiliate offer

OLED stands for Organic Light Emitting Diode. An OLED display is comprised of thin sheets of electroluminescent material, the main benefit of which is they produce their own light, and so don"t require a backlight, cutting down on energy requirements. OLED displays are more commonly referred to as AMOLED displays when used on smartphones or TVs.

As we"ve already covered, the AM part of AMOLED stands for Active Matrix, which is different from a Passive Matrix OLED (P-OLED), though these are less common in smartphones.

Super AMOLED is the name given by Samsung to its displays that used to only be found in high-end models but have now trickled down to more modestly specced devices. Like IPS LCDs, Super AMOLED improves upon the basic AMOLED premise by integrating the touch response layer into the display itself, rather than as an extra layer on top.

As a result, Super AMOLED displays handle sunlight better than AMOLED displays and also require less power. As the name implies, Super AMOLED is simply a better version of AMOLED. It"s not all just marketing bluster either: Samsung"s displays are regularly reviewed as some of the best around.

The technology debuted with the obscure Royole FlexPai, equipped with an OLED panel supplied by China"s BOE, and was then used in the Huawei Mate X (pictured above) and the Motorola Razr (2019), where both also sport BOE"s panel - and the Galaxy Flip and Fold lines, using the component supplied by Samsung Display.Affiliate offer

Resolution describes the number of individual pixels (or points) displayed on the screen and is usually presented for phones by the number of horizontal pixels — vertical when referring to TVs and monitors. More pixels on the same display allow for more detailed images and clearer text.

To make it easier to compare different models, brands usually adopt the same naming scheme made popular by the TV market with terms like HD, FullHD and UltraHD. But with phones adopting a wide range of different screen proportions, just knowing that is not enough to know the total pixels displayed on the screen.Common phone resolutions

But resolution in itself is not a good measure for image clarity, for that we need to consider the display size, resulting in the pixel density by area measured by DPI/PPI (dots/points per inch).Affiliate offer

Speaking of pixel density, this was one of Apple"s highlights back in 2010 during the launch of the iPhone 4. The company christened the LCD screen (LED, TFT, and IPS) used in the smartphone as "Retina Display", thanks to the high resolution of the panel used (960 by 640 pixels back then) in its 3.5-inch display.

The name coined by Apple"s marketing department is applied to screens which, according to the company, the human eye is unable to discern the individual pixels from a normal viewing distance. In the case of iPhones, the term was applied to displays with a pixel density that is greater than 300 ppi (dots per inch).

With the iPhone 11 Pro, another term was introduced to the equation: "Super Retina XDR". Still using an OLED panel (that is supplied by Samsung Display or LG Display), the smartphone brings even higher specs in terms of contrast - with a 2,000,000:1 ratio and brightness level of 1,200 nits, which have been specially optimized for displaying content in HDR format.

As a kind of consolation prize for iPhone XR and iPhone 11 buyers, who continued relying on LCD panels, Apple classified the display used in the smartphones with a new term, "Liquid Retina". This was later applied also to the iPad Pro and iPad Air models, with the name defining screens that boast a high range and colour accuracy, at least based on the company"s standards.

Nit, or candela per square meter in the international system (cd/m²), is a unit of measurement of luminance, i.e. the intensity of light emitted. In the case of smartphone screens and monitors in general, such a value defines just how bright the display is - the higher the value, the more intense the light emitted by the screen.

The result is smoother animations on the phone, both during regular use and in games, compared to screens that have a 60 Hz refresh rate which remains the standard rate in the market when it comes to displays.

Originally touted to be a "gimmick" in 2017, with the launch of the Razer Phone, the feature gained more and more momentum in due time, even with a corresponding decrease in battery life. In order to make the most of this feature, manufacturers began to adopt screens with variable refresh rates, which can be adjusted according to the content displayed - which is 24 fps in most movies, 30 or 60 fps in home video recordings, and so forth.

To further muddy the alphabet soup that we"ve come across, you will also run into other less common terms that are often highlighted in promotional materials for smartphones.

TFT(Thin Film Transistor) - a type of LCD display that adopts a thin semiconductor layer deposited on the panel, which allows for active control of the colour intensity in each pixel, featuring a similar concept as that of active-matrix (AM) used in AMOLED displays. It is used in TN, IPS/PLS, VA/PVA/MVA panels, etc.

LTPS(Low Temperature PolySilicon) - a variation of the TFT that offers higher resolutions and lower power consumption compared to traditional TFT screens, based on a-Si (amorphous silicon) technology.

IGZO(Indium Gallium Zinc Oxide) - a semiconductor material used in TFT films, which also allows higher resolutions and lower power consumption, and sees action in different types of LCD screens (TN, IPS, VA) and OLED displays

LTPO(Low Temperature Polycrystaline Oxide) - a technology developed by Apple that can be used in both OLED and LCD displays, as it combines LTPS and IGZO techniques. The result? Lower power consumption. It has been used in the Apple Watch 4 and the Galaxy S21 Ultra.

LTPO allows the display to adjust its refresh rate, adapting dynamically to the content shown. Scrolling pages can trigger the fastest mode for a fluid viewing, while displaying a static image allows the phone to use a lower refresh rate, saving the battery.

Among televisions, the long-standing featured technology has always been miniLED - which consists of increasing the number of lighting zones in the backlight while still using an LCD panel. There are whispers going around that smartphones and smartwatches will be looking at incorporating microLED technology in their devices soon, with it being radically different from LCD/LED displays as it sports similar image characteristics to that of OLEDs.

A microLED display has one light-emitting diode for each subpixel of the screen - usually a set of red, green, and blue diodes for each dot. Chances are it will use a kind of inorganic material such as gallium nitride (GaN).

By adopting a self-emitting light technology, microLED displays do not require the use of a backlight, with each pixel being "turned off" individually. The result is impressive: your eyes see the same level of contrast as OLED displays, without suffering from the risk of image retention or burn-in of organic diodes.

Another thing to be wary of is the price - at 170 million Korean won (about US$150,330 after conversion), that is certainly a lot of money to cough up for a 110-inch display.

Each technology has its own advantages and disadvantages but in recent years, OLED screens have gained prominence, especially with the adoption of the component in high-end flagship smartphones. It gained an even greater degree of popularity after the launch of the iPhone X, which cemented the position of OLED panels in the premium segment.

As previously stated, OLED/AMOLED screens have the advantage of a varied contrast level, resulting from individual brightness control for the pixels. Another result of this is the more realistic reproduction of black, as well as low power consumption when the screen shows off dark images - which has also helped to popularize dark modes on smartphones.

In addition, the organic diodes that give OLED screens their name can lose their ability to change their properties over time, and this happens when the same image is displayed for a long period of time. This problem is known as "burn-in", tends to manifest itself when higher brightness settings are applied for long periods of time.

In the case of LCD displays, the main advantage lies in the low manufacturing cost, with dozens of players in the market offering competitive pricing and a high production volume. Some brands have taken advantage of this feature to prioritize certain features - such as a higher refresh rate - instead of adopting an OLED panel, such as the Xiaomi Mi 10T.

Market forces made us endure screens interrupted with various sorts of notches and cutouts for a considerable time, but that’s all about to end soon. In the last few years, we have seen the Android community evolve from hating notches to being indifferent towards them. But living with the new wave of bezel-less, full-view display phones has convinced us that the world is better off without notches and it’s imperative that natural order be restored to our phone screens. (हिंदी में पढ़िए)

For now, most of the true full-view and notch-less display phones use Pop-up cameras or sliders, but a few tech giants including Samsung, Oppo, and Xiaomi have already demonstrated prototypes or released phones that place the front camera behind the screen.

Samsung Galaxy Z Fold 3 5G is the world’s first commercially available phone with an under-display camera (UDC). The main screen of this foldable phone is a 7.6-inch Dynamic AMOLED 2X panel with a 22.5:18 aspect ratio, QXGA+ (2208 x 1768) resolution, 120Hz refresh rate, and 374ppi. Thanks to that UDC, you get a 88.57 % screen to body ratio.

Xiaomi’s Mi Mix 4 is yet another under-screen camera phone. It calls its implementation CUP (Camera Under Panel), but the mechanism is pretty much the same as the other under-display selfie cameras out there. Above its 20MP selfie camera lies 400ppi pixels of the screen. This display stretches 6.67-inches and sports 120Hz refresh rate.

Asus Zenfone 8 Flip has a 6.67-inch (2400 × 1080 pixels) Full HD+ E4 AMOLED HDR10+ display with 90Hz refresh rate, 200Hz touch sampling rate, 110% DCI-P3 color coverage, up to 1000 nits brightness, and Corning Gorilla Glass 6 protection. This full screen fascia is possible thanks to a flip camera module.

OnePlus was one of the first few Android OEMs to usher in a notch, and it’s also one of the first in the premium segment to get rid with OnePlus 7 Pro (review). It further continued the trend with OnePlus 7T Pro which comes with a gorgeous true full-view display with extremely narrow bezels.

The elevating module opens like a fin and also makes room for the earpiece and LED flash. Anyway, the result is an immersive full-view AMOLED display that extends edge to edge. The Reno 10X Zoom has flagship-grade specs, including the Snapdragon 855, but all the tech housed within makes it a tad thick and heavy.

The 6Z (globally known as the Zenfone 6) is one of the most impressive phones we have seen from Asus in India. The 6Z (review) has a gorgeous and well-calibrated IPS LCD display that covers the entire facia. The selfie camera is housed in a flip module and this glass body phone houses a massive 5000mAh battery while being reasonably manageable.

Xiaomi’s Redmi K20 Pro (review) brandishes an impressive set of specs that you’d otherwise find on phones priced significantly higher. With the K20 Pro, Xiaomi pays due attention to design and the phone gets a full-view AMOLED display (6.4-inch, full HD+) with an in-display fingerprint sensor lying underneath.

Oppo Reno, which is a trimmed-down version of the Oppo Reno 10X Zoom, has the same design with shark-fin pop-up and is also slimmer and significantly lighter. The handset has a 6.4-inch AMOLED display (Full HD) with around 87% screen-to-body ratio that targets DCI-P3 color gamut and is shielded by Gorilla Glass variant.

Motorola One Fusion Plus rocks a 6.5-inch full HD+ notch-less TFT-LCD screen. It’s pop-up camera houses a 16MP sensor. Pivot and by the back you get a 64MP quartet.

The Realme X (review) is a very competent phone that includes trendy features like a full-view AMOLED screen with minimal bezels on three sides, in-display fingerprint sensor, and pop-up camera – all for a sub Rs. 20,000 price.

Redmi K20 passes on most of what’s good with the Redmi K20 Pro at a lower price point. The handset has the same design as the Pro variant and the same immersive full-view AMOLED display.

The Redmi K20 is however driven by Snapdragon 730 and replaces the Sony 48MP sensor with a Samsung sensor of the same resolution. Other features include in-display fingerprint reader, Pop-up camera, and 4000mAh battery with fast charging.

The Vivo 15 Pro has been around for a while, but it’s still a relevant option, especially at the new price. Both the V15 Pro and V15 employ a pop-up front camera and have a full-view display. The Pro variant, however, benefits from a better AMOLED screen and is powered by Snapdragon 675.

Huawei Y9 Prime is the first Huawei phone in India to deliver a full-view screen. The IPS LCD display on the phone measures 6.59-inch and is full HD sharp.

Samsung has developed one of the best full-view display devices globally. One such example of the same is the Samsung Galaxy Note 20 Ultra. The smartphone has a 6.9-inch dynamic AMOLED display complemented with a 120HZ refresh rate. The device has 12GB RAM and 256GB internal storage that can be expanded up to 1TB via a microSD card. It is powered by Samsung’s own Exynos 9 series processor.

iQOO took the whole market by storm with the launch of the iQOO 9 Pro 5G. The smartphone stands as a strong competitor of devices like the OnePlus 9 Pro in the market. It comes with a 6.78-inch AMOLED display that also has a 120Hz refresh rate to offer a smoother experience. The smartphone runs on the Qualcomm Snapdragon 8 Gen 1 processor paired with 12GB RAM and 256GB internal storage in the high-end variant of the device.

The Xiaomi 12 Pro could be hailed as one of the best devices launched by the company so far. The smartphone has a 6.73-inch AMOLED display with a 120Hz refresh rate The smartphone works on the Qualcomm Snapdragon 8 Gen 1 processor for high-speed performance, It also has 8GB RAM and 256GB internal storage to store all your data.

The flagship devices by Vivo have always amazed the users in terms of camera prowess, performance, and display capabilities. Vivo X70 Pro follows the same trend with its 6.56-inch AMOLED display coupled with a 120Hz refresh rate. Though we will say that the smartphone lags behind in terms of the processor as it has a MediaTek Dimensity 1200 processor. Apart from that, it has 8GB RAM and 128GB internal storage that cannot be expanded.

The OnePlus 10 series failed to make an impact like the OnePlus 9 series due to the changes and experiments. Still, the OnePlus 10 Pro was something which the audience loved because of the specs. The device works on the Qualcomm Snapdragon 8 Gen 1 processor with 12GB RAM and 256GB internal storage. The smartphone comes equipped with a Fluid AMOLED display and 120Hz refresh rate.

The Samsung Galaxy S21 FE packs a compact 6.4-inch Dynamic AMOLED display along with a 120Hz refresh rate. The device runs on the Samsung Exynos 2100 processor accompanied by 8GB RAM and 128GB internal storage that is non-expandable in nature. The smartphone operates on the Android 12 operating system offering the user a snappy interface without lots of bloatware.

In recent years OLED technology has emerged as the leading smartphone display technology, and the world"s most popular phone vendors are all shipping AMOLED smartphones.

In 2018, over 500 million AMOLED screens were produced - mostly to satisfy demand from mobile phones vendors. The smartphone OLED 2018 market was led by Samsung, whohas been using AMOLEDs in its high-end phones for many years, followed by Apple, LG, Xiaomi, Huawei and others. Samsung is branding its smartphone OLED displays as Super AMOLED display.

Most premium phones today adopt flexible OLED displays. Apple for example is using a flexible 5.8" 1125x2436 OLED (made by SDC) in its 2018 iPhone XS (the iPhone XS Max sports a larger 6.5" 1242x2688 flexible AMOLED). Display experts say that the iPhone XS Display is the world"s best smartphone display.

Most display experts and consumers agree that OLED displays are the world"s best smartphone displays. The best smartphone OLED displays are the Super AMOLED displays produced by Samsung Display, but other OLED producers (such as LG and BOE Display) are also producing high quality OLEDs.

The "p-display" nomenclature used in this article refers to the number of pixels displayed across the width of a given phone"s screen. Earlier phones with lower than 720p (lower than HD ready resolution) are not included in this listing.

Hi guys, over the past few tutorials, we have been discussing TFT displays, how to connect and use them in Arduino projects, especially the 1.8″ Colored TFT display. In a similar way, we will look at how to use the 1.44″ TFT Display (ILI9163C) with the Arduino.

The ILI9163C based 1.44″ colored TFT Display, is a SPI protocol based display with a resolution of 128 x 128 pixels. It’s capable of displaying up to 262,000 different colors. The module can be said to be a sibling to the 1.8″ TFT display, except for the fact that it is much faster and has a better, overall cost to performance ratio when compared with the 1.8″ TFT display. Some of the features of the display are listed below;

TheTFT Display, as earlier stated, communicates with the microcontroller over SPI, thus to use it, we need to connect it to the SPI pins of the Arduino as shown in the schematics below.

Please note that the version of the display used for this tutorial is not available on fritzing which is the software used for the schematics, so follow the pin connection list below to further understand how each pin of the TFT display should be connected to the Arduino.

When connecting the display, ensure that has a voltage regulator (shown in the image below) before connecting it directly to the 5v logic level of the Arduino. This is because the display could be destroyed if the version of the display you have does not have the regulator.

In order to allow the Arduino to work with the display, we need two Arduino libraries; the sumotoy TFT ILI9163C Arduino library which can be downloaded from this link and the popular Adafruit GFX Arduino library which we have used extensively in several tutorials. Download these libraries and install them in the Arduino IDE.

For today’s tutorial, we will be using the bigtest example which is one of the example codes that comes with the sumotoy ILI9163C Arduino library to show how to use the TFT display.

The example can be opened by going to File–>Examples–>TFT_ILI9163c–>bigtest as shown in the image below. It should be noted that this will only be available after the sumotoy library has been installed.

Next, an object of the ILI9163c library named “display” was created with CS and DC parameter as inputs but due to the kind of display being used, we need to include the pin of the Arduino to which the A0 pin of the TFT display is connected which is D8.

With this done, we move to the void setup() function. Under this function, we issue the commands that initialize the display then create a time variable updated by millis, after which we issue a command to clear the screen and display some random text on it.

Some of the functions which perform actions ranging from displaying fastlines, drawing rectangles etc are then called with a delay after each function so the text or graphics stays long enough on the screen to be visible.

Up next is the void loop function. The void loop function also calls some of the same functions called under the void setup() function to display circles, rectangles etc including the testline function which is essentially used to test the screen.

With the libraries installed, open an instance of the Arduino IDE, open the examples as described initially, don’t forget to make the A0 pin (D8) correction to the code then upload to the Arduino board. You should see different kind of text and graphics being displayed on the screen. I captured the screen in action and its shown in the image below.

That’s it for this tutorial guys, what interesting thing are you going to build with this display? Let’s get the conversation started. Feel free to reach me via the comment section if you have any questions about the tutorial.

TFT is an abbreviation for Thin Film Transistor, a flat panel display used to improve the operation and utility of LCD screens. In order to portray an appearance to the audience, a liquid crystal display (LCD) utilizes a crystalline-filled fluid to modify rear lighting polarized origin through the use of an electromagnetic force among two relatively thin metal wires such as indium oxide (ITO). However, color TFT displays are associated with this method, which can be employed in both divided and pixelated display systems.

With motion pictures displayed on an LCD, the intrinsic sluggish rate of increase between liquid phases over a significant number of pixel components can be an issue due to capacitance impacts, which can create a blurring of the visuals. Placing a high-velocity LCD control device inside the formation of a thin-film transistor immediately next to the cell component just on a glass screen, the issue of LCD picture speed may be substantially improved, and image blur can be eliminated for all useful purposes entirely.

Organic light-emitting diodes (AMOLEDs) are a type of flat light-emitting advanced technologies that are created by interspersing a succession of organic thin sheets over two conducting conductors. An electrical charge causes a brilliant light to be produced when the current flows. AMOLED displays are light-emitting screens that do not require a backlight, making them thinner and more energy-efficient than liquid crystal displays (LCDs) (which will need a white backlight).

AMOLED displays are not only thin and fuel-intensive, but they also deliver the highest image quality available, so they can be made translucent, elastic, bendable, or even rollable and stretchy in the future, allowing for a variety of applications. AMOLEDs are a revolutionary technology in terms of display devices! It is possible to create an AMOLED by sandwiching a sequence of thin films across phase conductors. Electric charge causes a brilliant light to be emitted when the current flows through the coil.

The color display is fantastic. Color intensity, sharpness, and luminance settings that are second to none and can be customized to meet the needs of any application.

Half-Life has been expanded. TFT displays have a far longer half-life than its LED equivalents, and they are available in a number of sizes, which might have an effect on the device"s half-life based on the phone"s usage as well as other variables. Touch panels for TFT screens can be either resistant or capacitance in nature.

As it is more affordable than capacitive, resistive is typically the preferred option. However, capacitive technology is compatible with a wide range of contemporary smartphones and digital gadgets.

Due to the apparent glass panels, there is limited functionality. For instance, there are ineffective for outdoor use because the glass can display glares from its natural lighting)

They rely on backlight to give illumination rather than generating their own light. Hence they require constructed light-creating diodes (LEDs) in their backlit display framework to ensure enough brightness.

Due to the fact that AMOLED displays inherently emit illumination, they do not need a backlight when used on a monitor screen. Conversely, LCDs require backlights since the liquid crystals themselves are incapable of producing light under their own. Direct light emission from AMOLED displays also allows for the developing of lightweight display devices than others using TFT LCDs.

LCD displays have a higher brightness than AMOLED panels. This is owing to the LCD"s usage of led backlight, which may provide a brilliant illumination of the entire display. Despite the fact that AMOLEDs produce high levels of brilliance from their illumination, they will never be able to match the intensity of LCD lighting.

LCD screens use less power than AMOLED displays, which provides a slight advantage. The amount of energy consumed by AMOLED displays is dependent on the intensity of the screen. Lowered luminance results in lower energy usage, however, it might not be the best solution because the contrast would suffer as a result of the decreased brightness. In some situations, such as when to use an AMOLED device in direct sunlight, it is not an optimal situation.

However, the backlit keys of TFT displays account for the majority of their power usage. TFT screens" efficiency is considerably improved when the backlight is set to a lesser brightness level than the default setting. For example, replacing the light of an LCD TV with just an Led flash will have no effect on the image quality, but will result in lower power usage than replacing the light of an AMOLED TV.

With the exception of phones, numerous other technologies make use of displays to allow customers to engage in direct communication with them. To determine whether or not TFT LCD will be able to withstand the development of AMOLED innovation, we should first review the benefits of LCD technology. The backlighting quality ensures that whites are strong and brightness is superb but will deplete a battery much more quickly than just an AMOLED display. Furthermore, the cost of LCD screens is a considerable consideration. In addition to being less expensive and more easily accessible, they are produced in standard industry sizes, allowing them to be purchased for innovative products with relative ease.

Top-tier smartphones all come with excellent cameras and usually feature multiple rear sensors. You typically get a primary sensor for regular shots, an ultrawide sensor for wide-angle shots, a depth sensor for bokeh, and a telephoto sensor for zoomed shots. This is true of top phones from Apple, Samsung, OnePlus, Google, and others. The Google Pixel lineup is particularly well known for its great software augmentation, allowing for improved low-light shots and post-processing. Both the latest iPhone and Samsung flagships have a great hardware array and AI-enhanced shooting. Take a look at our list of the best smartphone cameras for more details.

The humble telephone has come a long way over the years. Gone are the days when the phone was simply a way to call people. These days, smartphones are the hub of our digital lives, serving as a way to communicate with people, surf the Web, play games, pay bills, stay organized, and more.

There are a few companies developing processors for smartphones. Apple develops its own processors in-house, but the likes of Qualcomm, MediaTek, Samsung, and more, all develop processors for Android phones. In the U.S., Qualcomm chips are most common, and in 2018, the flagship Qualcomm chip is the Snapdragon 845. The higher the number here, the better.

The most common type of display type in mid-range and low-end phones is the LCD, or Liquid Crystal Display. LCDs are inexpensive to produce, which is why they’re used so often, but the trade-off is that they’re not the best at conserving battery life and they generally don’t produce the deepest blacks or brightest colors. There are two types of LCD’s though: TFT-LCDs, which are cheaper and the worst at color reproduction, and IPS-LCDs, which are a little better at color reproduction and wider viewing angles.

These days, high-end phones are doing away with LCDs in favor of OLED displays. Because OLED displays light up individual pixels rather than the display as a whole, it saves on battery life. On top of that, when black shows up on the screen, OLED displays simply don’t light it, meaning that blacks look deeper, and contrast ratios are higher. You might see “Super AMOLED” displays out there, which is basically Samsung branding for its OLED displays.

You’ll probably only notice the difference between LCD and OLED displays if you have a truly sharp eye, although you might find the battery improvements that come with OLED displays to be worth the extra cash.

Phone display sizes have gotten a whole lot bigger over the years, and that might be important to you. Smaller displays come in at four inches, while larger displays can range up to seven inches.

Gone are the days when you had to enter a PIN code to access your phone. These days, most smartphones have a fingerprint sensor built into them, ensuring you can get into your device quickly and easily, and at the touch of a sensor. Some higher-end phones also have other forms of biometric authentication, like iris scanning or facial recognition.

Not all batteries are the same size, and a smaller battery can have a serious impact on how long your phone lasts on a single charge. Battery capacity is measured in milliampere-hours, or mAh—where a higher number represents a larger capacity. Of course, it’s not always as simple as “larger batteries make your phone last longer.” A phone with a larger battery but an equally high-resolution display and power-hungry processor may not last as long as a phone with a smaller battery, lower-resolution display, and less intense processor.

Thanks for the display technology development, we have a lot of display choices for our smartphones, media players, TVs, laptops, tablets, digital cameras, and other such gadgets. The most display technologies we hear are LCD, TFT, OLED, LED, QLED, QNED, MicroLED, Mini LED etc. The following, we will focus on two of the most popular display technologies in the market: TFT Displays and Super AMOLED Displays.

TFT means Thin-Film Transistor. TFT is the variant of Liquid Crystal Displays (LCDs). There are several types of TFT displays: TN (Twisted Nematic) based TFT display, IPS (In-Plane Switching) displays. As the former can’t compete with Super AMOLED in display quality, we will mainly focus on using IPS TFT displays.

OLED means Organic Light-Emitting Diode. There are also several types of OLED, PMOLED (Passive Matrix Organic Light-Emitting Diode) and AMOLED (Active Matrix Organic Light-Emitting Diode). It is the same reason that PMOLED can’t compete with IPS TFT displays. We pick the best in OLED displays: Super AMOLED to compete with the LCD best: IPS TFT Display.

Smartphones are now more powerful than ever, and a portable monitor can help you unleash the phone"s additional capability. With the assistance of a portable monitor, you can quickly turn your smartphone into a primary computer to perform productive works on a bigger screen.

Using a single USB C cable to connect your smartphone with a portable monitor, both devices need to feature a USB C portenabled by DisplayPort Alt Mode (DP Alt Mode). Moreover, the USB C cable also needs to arrive with the Alt Mode capability to transfer the video signals.

Some smartphones that include the DisplayPort capability have the Samsung Galaxy Note Series, Samsung Galaxy S series, flagship HTC U series, Huawei Mate, and Huawei P series. In addition, some of the smartphones from the LG G & V series and the Razer and ROGH phone also include this functionality. You can also go through thiscompatible listto find out the other DP Alt Mode Compatible Devices.

The Panasonic Toughbook FZ-T1 is part of the latest fully-rugged handheld series from Panasonic and I know that when thinking about the toughest phones, most people will point to the Samsung Active series (or some other Chinese brands), but Toughbook devices are simply on another level in terms of ruggedness. I found it a bit amusing when Panasonic was referring to its 5-inch handsets as tablets that can make phone calls (which is not really wrong) and the Toughbook FZ-T1 is now a handheld and the Wi-Fi/4G version has all the functions of a normal smartphone. The way it is built and the additional features it has, clearly sets it apart even from the rest of the rugged smartphones and the closest device that I could find is the Cat S61 (due to its thermal imaging camera).

I held myself back for a while to include this product for more than a couple of reasons: it is unfortunately not suitable for the usual consumer and it’s specifically built for industry workers (mostly due to the integrated barcode scanner). That’s right, the Toughpad FZ-T1 features a thick case (which measures 3.0 x 6.1 x 0.7 inches including the barcode reader section – significantly slimmer than the N1 model), a fairly rounded back panel to keep the device comfortably in your hand and the black matte finish does help with the grip (so you don’t drop it). On the front of the device, just above the display, there’s a small battery indicator (when it’s red, the battery level is 10% or less), the ambient light/proximity sensors and the microphone.

Underneath the display, there is a mono speaker (can go up to 95dB) and a microphone – yes, the three physical buttons (Back, Start and Search) are now gone and replaced by the on-screen alternative. I think that all rugged smartphones should keep the physical buttons and not migrate towards a display-only approach, but I’m willing to give Panasonic a pass due to the glove mode (allows you to use the phone with thick gloves) and rain mode (makes sure that there are no misoperations if the display gets we – (the process involves limiting the touchscreen multi-touch usability from 10 fingers to just one finger).

The large part of the front side is occupied by the 5-inch display, which has a resolution of 1280 x 720 pixels (a bit disconcerting for a 2-year old rugged phone), a pixel density of around 294ppi and up to 500cd/m2 brightness levels (seems to be the same as on the far older Toughpad FZ-E1). Yes, the display is outdated and I know that the focus was more towards functionality and less about entertainment, but even so it’s a bit ridiculous considering the price tag (the CAT S61 is also fairly industrial, but has a far batter display). That being said, the pixel density is low, the colors aren’t really as vibrant as what other cheaper phones from the competition have to offer and the viewing angles aren’t that great. Now, since this is a rugged device, it is expected that the screen won’t shatter easily and this is true for the most part since it can be dropped from 10 feet without taking any damage (the thick border that surrounds the display plays an important part) and it will survive without problems a lot of drops (yes, even face-first ones – it’s surprisingly difficult to destroy this device).

Furthermore, the Toughbook FZ-T1 is also MIL-STD-810G certified, so it can handle both high and low temperatures (the operating range is between -4 and 122 degrees Fahrenheit), explosive atmosphere, humidity, sand and dust, vibration (including loose cargo transportation), shock, freezing rain, acidic atmosphere and more. As expected, the Toughbook FZ-T1 is also waterproof and dust resistant, being both IP66 and IP68 rated, so you can submerge it down to 5 feet underwater for about 30 minutes. Inside the case, the Panasonic Toughbook FZ-T1 is equipped with a quad-core Qualcomm 210 MSM8909 chipset (the clock rate can go up to 1.1GHz), an integrated Adreno 304 graphics card, 2GB of RAM and 16GB of eMMC storage memory – you can add up to 64GB by using a microSD card. The device is also compatible with the following wireless and Voice&Data standards: IEEE802.11 a/b/g/n/d/h/i/r, Bluetooth, 4G LTE, HSPA+, UMTS, EDGE, GPRS and GSM. Seeing these specs, it does feel like Panasonic took a significant step backwards since the Qualcomm Snapdragon 210 MSM8909 is the entry-level SoC for Android smartphone, so the performance is not going to be that great (some resource-heavy apps are not going to work properly, but multi-tasking is decent due to the 2GB of RAM and especially thanks to the display resolution); the Adreno 304 paired with the 720p should be fine, but even so, most games will not run smoothly.

The ToughPad FZ-T1 uses Android 8.1 Oreo and it’s an interesting choice, considering that past devices from Panasonic relied on the Windows Mobile and it made sense since it had a better integration with various software from tech and industry companies. The Android OS is going to feel more comfortable for most users and I suppose this handheld rugged device doesn’t really need any special apps – as with other manufacturers of rugged smartphones, Panasonic doesn’t seem to like to update the OS on its devices.

Verdict: Why isn’t the Panasonic Toughbook FZ-T1 the first in the list you may ask, since it’s such a great rugged device? Well, because it doesn’t really follow the same guidelines as the usual smartphones (or tablets, for that matter) and, while it’s true that rugged cell phones, in general, are more niche devices, the Panasonic Toughbook FZ-T1 is even more narrow into the targeted audience. To be more specific, this belongs in a warehouse with industrial workers and I highly doubt I’ll ever see an active person running with this mammoth strapped to their arm. That being said, the Panasonic Toughbook FZ-T1 is pretty much the pinnacle of ruggedness, having a screen resistant to shock, the case can handle pretty much everything you throw at it, it has some awesome features (suitable for an industrial environment), but there are some minuses, since software is a bit outdated, the camera is nothing to brag about (and the front-facing one is completely missing), the device is quite thick and the most important negative is the incredibly high price.
