The technology used behind the screen to produce colors on the display varies on different smartphones and laptops. The display type have direct interaction with the user and hence are important in choosing the right one. Different screens use different technology in producing colors. They not only differ in color reproduction, but also in power consumption, sunlight readability and many other factors.
The major types of display used are:
- LCD – Liquid Crystal Display
- IPS-LCD – In-Plane Switching Liquid Crystal Display
- AMOLED – Active Matrix Organic Light Emitting Diode
- OLED – Organic Light Emitting Diode
Each display has its own distinct characteristics because of the mechanisms used in them. Their performance differ in many conditions. Their ability vary in Color calibration, Contrast ratio, Color depth, Sunlight readability, brightness, and Color reproduction.
LCD are collective Liquid crystals that doesn’t have its own light emitters. They use some extra back lights to illuminate the display. only the filters in the LCD corrects the needed color to be represented at the display end. They can also be comfortably viewed in sunlight.
The In-Plane Switching LCD has an advantage of wider viewing angles. They are also better in color representation when compared to LCD screens. Most mobile phones now use IPS LCD screens for their display. Since they have a consistent and clear colors in most viewing angles with a stable response time.
These Light Emitting Diodes uses self lit panel, making the substrate very thin. They are also better in color contrast ratio. With a deeper black, producing more reality colors.
OLED - AMOLED
The Organic LED is capable of providing individual pixel powering. This means, it lights up only the area that needs to be lighted. Other pixel areas will be turned off. Thus improving the energy efficiency and providing deep blacks.
These display works without any backlight and filters as in previous display techs. It can be made thinner and lighter than the liquid crystal displays (LCD). In low ambient light conditions, an OLED screen can produce a higher contrast ratio than the LCD. They are also very much energy saving. Their interesting properties not only end here, they also have the ability to bend. They are thin enough to roll it out.
The AMOLED – Active Matrix OLED generates light, which is integrated to a Thin Film Transistor (TFT) which can control individual pixels. The Green and Red films have a comparatively longer life making the Blue Film to fade away sooner. This makes the screen to look slightly burned.
