What is TFT?
Thin Film Transistor, each pixel on a TFT-LCD has its own transistor on the glass itself, which offers more control over the images and colors that it renders.
TFT is active matrix display technology and is more responsive to change, is fast enough to reflect the movement. TFT LCDs are used in appliances including: TV, Mobile phones, handheld systems, personal digital assistants, car navigation and instrument cluster systems, and a lot of different application.
Organic Light-Emitting Diode, the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. There is no need to has the backlight added behind the panel as LCD did.
E Ink (electronic ink) is a paper-like display technology, characterised by high brightness and contrast, a wide viewing angle, and ultra-low power requirements.
E Ink are Electrophoretic: tiny little capsules embedded in a transparent plastic sheet. Contain two kinds of particles with different charges: black and white. By controlling the voltage applied across the sheet, the particles can be move to one side or the other inside the capsule, so creating white and black and so change the color of the pixel. Those particles remain in place when no electricity is used and require power when image need to change.
