Display technologies

There are many display technologies available on the market, the two main technologies

used are described below:

•

LCD-TFT displays (liquid crystal display - thin film transistor): is a variant of LCD that

uses the TFT technology to improve the control of each pixel. Thanks to the TFT

technology, each pixel can be controlled by a transistor, allowing a fast response time

and an accurate color control.

•

OLED displays (organic LED): the pixels are made of organic LEDs emitting directly the

light, offering a better contrast and an optimized consumption. The OLED technology

enables the possibility to use flexible displays, as no glass nor backlight are required.

The response time is very fast and the viewing angle is free as it does not depend on

any light polarization.

The way of driving the display module is quite similar in TFT and OLED technologies, the

main difference is in the backlight requirement, as the OLED is not requiring any.
