OLED is to rely on self-luminescence to display images, do not need to use backlight, not affected by ambient light, the general life expectancy is about 5000 times TFT is an active matrix type liquid crystal, need to use the brightness of the backlight to display the image, will be subject to ambient light Affected, the general life expectancy is about 20,000 times. The OLED (Organic Light Emitting Display) organic light-emitting display has an essential difference from the conventional LCD display, ie, it does not require a backlight source. It uses a very thin organic material coating and a glass substrate. These organic materials emit light when current passes through them. Therefore, the OLED LCD panel can be made lighter and thinner, with a larger viewing angle and at the same time more power saving. However, the service life is short and there is no way to make the screen bigger. OLEDs are mostly used for folding mobile phone external screens.
TFT-LCD (Thin-Film Transistor) thin film transistor abbreviations, is currently the top material LCD screen, belonging to the active matrix type LCD screen, the back with a special lamp, can be "actively" independent on the screen The pixels are controlled, which is what we often call Active Matrix TFTs. The response time is relatively fast, about 80 milliseconds, and the viewing angle is large, usually about 130 degrees. It is used in some high-end models. Since the arrangement of the TFT liquid crystal panels has memory, it will not be restored immediately after the current disappears, effectively improving the ability to play dynamic images. The disadvantage is that it consumes more electricity and the manufacturing cost is higher.
OLED color screen is 30% more expensive than the same size TFT color screen. The biggest difference between true color OLED screen and TFT screen is that OLED true color screen has a very high screen contrast and a fuller degree of color reproduction. OLED true color screen is better than TFT screen in terms of backlight performance and brightness.
