An overall attribute of display in smart phones

When you take what a mobile phone from a decade ago and compare, the transformations witnessed is from a small device with keypad and small display into a larger device with nothing but the display screen. Henceforth this transformation, the display factor is now one of the prime aspects of a phone. Conventional devices were primarily used for calling and messaging but this functionality has now shifted from primary to secondary as the devices today are extensively used for multimedia.

Latest android phones are battling to get ahead in the race for creating the best user friendly displays, which offer more vivid colors and all-embracing details while viewing any content. The display size is one of the most important issues to deal with, as the size of the screen greatly influences the viewing experience. For an example, text appears larger in large screen and gaming on larger devices is more appealing than on smaller screens.

Resolution of a display is the number of distinct pixels which can be displayed on the smartphone. Latest smartphones are competing in the race to acquire the device with the highest resolution, but is that really necessary? Although having a high resolution results in less pixilation and great viewing experience, smaller displays with high resolution is unnecessary. Escalating the resolution count higher and higher results in the saturation i.e. it gets impossible to differentiate a high resolution with a lower one.

Some of the best mobile devices are said to have 4K display, which although is a huge accomplishment, also rather unnecessary. 4K or 3840 pixels × 2160 lines is an ultra-high resolution which was targeted to consumer television but now being introduced to the market of cell phone. Having a 4K display in a device around 5 inch of diagonal is meaningless as the users might not even tell the difference between the 4K display and a full HD display. Nevertheless, 4K display devices are prone to low battery life due to illumination of the extra pixels.

Display on a hardware level is influential to the representation of content. Displays like AMOLED, OLED, IPS, Retina display, LCD etc. are some of the most popular display panels brought in use by many smart phone manufacturers. IPS LCD display is found in many high end devices which offers great viewing angle (content is visible from far wide angles) and consumes less power. OLED displays on the other hand have great color representation, fast response time, even wider viewing angles and are extremely bright making them visible directly in sunlight. Similar to OLED but AMOLED can control each pixels individually but come with a hefty price tag. Finally, retina display has great pixel density and high contrast ratio which means the whites are brighter and the blacks are deeper.

Major time in the utility of the device we interact with the display and more advancement can be foreseen in the future as the urge to satisfy the users still remain in the manufacturers. Let us hope that the display technology still persists in the advancement towards users’ comfort and entertainment.
