Mobile phone device vary in display types and display size, and this is one attribute that may contribute to giving users an amazing viewing experience.
Although a phone with large screen may make everything displayed on it clear, believe me the screen size is nothing if the phone’s resolution is poor.
One important factor that contributes to a wonderful viewing experience is the phones resolution.
Phones with high resolution always gives better display, this means the higher the resolution, the better the display.
These display resolutions have been represented with different acronyms that might seem confusing, you see acronym like HD, UHD, qHD and the likes.
The question now is what these acronyms represent; this is not a brain- teaser so you don’t have to think too hard because this post will take through a journey of the various display types.
Full HD ( FHD) or 1080p display was the standard display as many smartphone came with this display type. However, many smartphones brands like Huawei, Samsung etc are making the 2k display the standard for their latest smartphones.
It is worthy to note that this display types are not only seen in mobile phones but also applies to television sets.
Resolution plays a key role in the display of mobile phones; the resolution has to do with the screen size in inch and the pixel amount or pixel per inch (PPI).
The pixel per inch allows you figure out the amount of pixel a phone carries by estimating the screen size this process is known as the pixel density. In cases of estimation, pixel density calculator helps you calculate your phone’s pixel per inch.
Furthermore, the number of resolution on a phone has been represented with different acronyms. Acronyms like HD, qHD, full HD etc. contains different amount of pixels and the awesomeness of the phone’s display is dependent on the type of resolution it was built with.
High definition (HD) is a type of phone display; the HD has a pixel measurement of 1280 × 720 pixels. Mobile phone device can be manufactured with large screen or small screen and still come with 1280 × 720 pixel size.
However, when you are considering the pixel density, you will notice that the smaller the HD screen, the higher the pixel density. So this simply means a 5.5inches screen with 1280 × 720 pixels will depict a different image from a 6 inches screen with same pixel.
Full HD (FHD) is simply an upgraded HD, it is better and projects clearer images plus the pixel quantity is more than that of the HD. In addition, the full HD has a 1920 × 1080 pixel measurement which is said to be the standard for smartphones.
Just like in HD and all other display type, the screen size affects the pixel density, the smaller the screen the larger the pixel density.
For example a full HD smartphone with 5.0 inches screen size will have 440 PPI while a 5.5 inch will have 400 PPI.
First thing you should know about 2k resolution is that it is also referred to as quad HD or QHD, this display is four times the full HD (FHD). With the 2k resolution, you can get 4 times the pixel of the FHD on a smartphone.
The 2k display measures 2560 × 1440 pixels which will give a larger pixel density with a smaller screen. 2k or the Quad high definition (QHD) should not be mistaken with the quarter high definition (qHD).
The various display types are usually represented by the smaller pixel measurement. For instance the HD 1280 × 720 is also referred to as 720p while the FHD display is referred to as 1080p.
On the other hand the QHD which has a pixel measurement of 2560 × 1440 is referred to as 2k display.
This name could be as a result of the fact that the higher pixel is above 2k, although one would have expected it to be called 1440p considering the alternative names of the previous display.
4k Ultra HD
The ultra HD resolution also follows the same naming pattern as the 2k resolution as it is also named using the higher pixel measurement. 4k measures 3860 × 2160 pixels or 4096 × 2160, even though both resolution measurements are ultra HD, they differ in some ways.
Aside it being a fantastic display type, 4k resolution has large pixel quantity which means better image for smartphones that comes with it.
One of the first smartphone that debut the release of the 4k resolution is the Sony xperia Z5 premium which projects amazing image on its 5.5 inch screen.
According to Sony xperia Z5 was built with a 4k resolution, but it was later noticed that the device has a resolution below 4k and a pixel density of 806 ppi which is still better than what is considered the standard for some top smartphone brand.
Why some mobile phone brand have not incorporated the 4k resolution
Individual’s expectations are becoming high with the rate at which new smartphones are introduced. We have been seeing new smartphones and the surprising thing is that these phones brand continues to incorporate the 2k resolution despite the fact that the 4k is already available.
Well these brand have good reasons for doing so, one reason might be the incessant issues with battery life of a phone. This reason is not far-fetched as a higher resolution will consume more power than a lesser resolution.
Rather than going higher on pixel quantity, many brand has introduced various display panels into their mobile phones.
Display panel is used by smartphones to improve photo quality, some popularly featured display panels are AMOLED, OLED, TFT, IPS etc. The type of display panel seen in smartphones depends on the price range of the phones.
LCD stands for liquid crystal display; this has to do with the liquid crystals that are illuminated by a back light. The LCD is usually found in low range device and this is because they are not so expensive to incorporate in smartphones.
The LCD is best in sunlight or high light condition and may not perform well in low light conditions.
TFT display panel
This is another type of display panel; it stands for thin film translator. This TFT is an advance LCD that uses an active matrix which attaches the pixels to a transistor and also to a capacitor.
TFT is not just better than LCD, it also has low production cost. However, most smartphone are manufactured with the LCD due to the fact that the TFT has higher energy demand plus the viewing angles and color production is not so impressive.
Just like smartphones, display panels are also improved and upgraded frequently. The IPS is a proved TFT which stands for in- plane switching. Furthermore, IPS produces better color and impressive viewing angles; the IPS is able to achieve this by using two transistors.
These transistors are used for each pixel along with a powerful backlight that illuminates brightly producing better color. This procedure requires more energy than the LCD, but the TFT still uses more energy than the IPS.

There are cases where acronyms like Neo will be attached to the IPS, this simply signifies a JDI created technology. This technology gurus claim to have solved the tgr back light leakage that occurs on the IPS.
AMOLED is actually an improved form of the thin film technology (TFT). AMOLED stands for active matrix organic light emitting diode. The OLED attached to the name is another term for the TFT, the OLED is an organic material that emits light when current pass through it.
One good thing about the OLED is that it consumes less energy and also produces more dark colors. When brighter colors are displayed on the OLED it consumes more energy than the LCD but produces more color. AMOLED or OLED display has high production cost so are usually featured in high-priced smartphones.
