What is the Screen Type of a Smartphone?
There are many different kinds of screen types available for smartphones and it is significant that we have a clue about these screen types before buying them. The screen also adds in test of screen types to know their Contrast Ratio, Color Calibration, Brightness and Sunlight Legibility.
Screen types include:
TFT stands for Thin Film Transistor technology. While LCD stands for Liquid Crystal Display displays which comprises of Liquid Crystals. LCD displays can be very observable in direct daylight. TFT LCDs are rampant type of screen components being used on mobile phones. TFT LCD comes with better image quality and advanced resolutions than to earlier LCD screens but their short comings lies in thin angles of view and less visibility in direct impact of light.
IPS stands for In-Place Switching. LCDs are higher than previous TFT LCD screens with broader viewing angles and consumes less power which leads to a much enhanced battery life. IPS-LCDs are more expensive than normal TFT LCD. This has become a common display type for mid-range to high-end phones.
OLED stands for Organic Light Emitting Diode. It is an enhanced screen technology for type of displays of phones and PCs. It utilizes ‘organic’ LEDs which releases light and in most cases does away with the need for the back-light of an LCD display resulting in a potentially thinner panel. In OLED technology a sheet of organic material (carbon built) is crammed between two conducting sheets (an anode and a cathode), which in turn are crammed between a glass top plate and a glass bottom plate. OLEDs produce excellent result than LCDs and also has fast reaction times, broader viewing angles, higher brightness and extremely light weight designs.
AMOLED stands for Active-Matrix Organic Light-Emitting Diode. It also utilizes ‘organic’ LEDs which discharges light and in the majority of cases does away with the need for the back-light of an LCD display resulting in a possibly thinner panel. AMOLED displays are a type of OLED screens for mobiles and are seriously gaining popularity in top end smartphone segment.
Super AMOLED screens are more advanced than AMOLED display screens and it is developed by the Korean tech giant; Samsung. Super AMOLED display is made with touch sensors on the screen itself, as contrasting to creating different touch sensitive layer (as in capacitive touchscreen).
