The Main Material of LCD
TFT is an abbreviation for Thin-Film Transistor. The TFT deposits a thin film on the glass substrate as a channel region, and improves image quality through thin film transistor technology. The TFT is configured with a semiconductor switching device for each pixel, and each pixel can be directly controlled by a dot pulse. And because each node is relatively independent, continuous control is possible. The TFT can control each independent pixel on the screen, so that the screen information can be displayed with high speed, high brightness and high contrast. The reaction time of the general TFT is about 80 milliseconds, and the viewing angle can reach about 130 degrees. It is widely used in phone LCD. And the speed of the reaction when swiping is also remarkable. It is the cheapest comparing with OLED and AMOLED. But it spends more power of electricity.
OLED is an abbreviation for Organic Light-Emitting Diode. Unlike the aforementioned TFT, OLEDs do not require backlight support. It is with self-illumination, and owns the advantages of wide viewing angle, high contrast, low power consumption, high reaction rate, full color, and simple process. The advantage of OLED is that its contrast and color reproduction are also better than ordinary TFT screens and very power efficient. However, due to the popularity of AMOLED and Super AMOLED, OLED screens are fading out.
AMOLED is a shorthand for the active matrix organic light-emitting diode . The biggest feature of the AMOLED screen is that it has self-luminous characteristics. Each pixel can emit light by itself. At the same time, the AMOLED also has a wide viewing angle and high contrast due to the elimination of the backlight. It is a kind of screen material derived from OLED. Characteristics : fast response, high contrast, wide viewing angle, excellent touch performance etc. And it is also very energy efficient. It is much expensive than other two ordinary screen.
Generally speaking , each material is with its advantage. TFT is with the most affordable price ,OLED is with good quality as well as cheap price and AMOLED is with the best quality.
