Different Type Of Smartphone Displays In The Market
Smartphone display is the main thing a user sees when buying a new mobile device. This is because the display screen happens to interact with the software and do various things. However, the display screen has evolved and today humans have reached the milestone of making flexible screens. There are quite a lot of display types used in mobile phones.
TFT LCD – (Thin Film Transistor technology)
TFT LCDs are supposedly the most common type of display units found in mobile devices. TFT LCD gives you good image quality and higher resolutions compared to earlier generation LCD displays however, in narrow viewing angles and in direct light or sunlight there’s poor visibility.
IPS-LCD – (In-Place Switching)
IPS LCDs are the next level of TFT LCD displays providing wider viewing angles and lower power consumption which leads to much-improved battery life. IPS-LCDs obviously are costlier than normal TFT LCD and hence located only on higher-end smartphones. A higher resolution (640 x 960 pixels) of IPS LCD is found n Apple iPhone 4 which is called Retina Display because of its brilliant picture quality.
Capacitive Touchscreen LCD
Capacitive touchscreen technology happens to have a layer of glass laced with a transparent conductor (like indium tin oxide). When touched by the human body (finger), an interruption is created in the screens electrostatic field (which is measurable as a change in capacitance) and this, in turn, is detected by the phone’s processor or chip and which in turn will instruct the phone’s operating system to trigger an event or action accordingly.
OLED – (Organic Light Emitting Diode)
This happens to be the newest technology in for displays of mobiles and monitors. As far as the OLED tech is concerned you will find an organic material which is placed between two conducting sheets (an anode and a cathode), which are also put between a glass top plate (seal) and a glass-bottom plate (substrate). The time an n electric pulse passes or is applied between the two conducting sheets, electro-luminescent light is produced directly from the organic material sandwiched between.
AMOLED – (Active-Matrix Organic Light-Emitting Diode)
AMOLED is a different type of OLED displays for mobiles and are fast gaining popularity in the top-end smartphone segment. AMOLED screens can show us many things that we are present on OLED display like brilliant color reproduction, lightweight, good battery life, proper brightness, etc.
Super AMOLED displays
Super AMOLED displays take upon the AMOLED displays and is primarily developed by Samsung. Super AMOLED is constructed with touch sensors placed on the display itself, as opposed to creating a separate touch-sensitive layer (as in capacitive touch screen). This makes it the thinnest display technology on the market. Super AMOLED displays are currently only present in Samsung devices but more phones could use the technology in the future.
