TFT LCD display with the advantage of color reproduction far superior to other types of display screens. The picture usually with high bright in color, high in saturation, and the pure white and pure black pictures are very pure. TFT is the one of the approved display screens by everyone.
For the same size display screen, the view angles of TFT LCD screen is larger. The view angles of TFT LCD screen is the same as its diagonal size. The IPS series of the TFT-LCD display screen can reach a full viewing angle of 178 degrees, which means that no matter which angle the user views the TFT-LCD display screen from, the effect is very good.
The application of TFT-LCD display is very wide, TFT were widely used as LCD devices in computers, notebook computers, also used in industry equipment, transportation equipment, medical treatment equipment, smart home, electric power, AR/VR and others.
TFT LCD display size is complete, the interface types abundant, and easy to development. This is an important reason why the terminal chooses the TFT-LCD display screen.
Many TFT LCD display can use in low temperature and high temperature, the usual operation temperature is -20 degreen to 60 degreen, but some TFT LCD display can operation on -20-70 degreen, and storage temperature reach to -30-85 degreen. That means you can use these LCDs display in most countries around the world, and even use outdoor.
Compared with the traditional LCD display screen, TFT LCD display with high resolution, It is easy to achieve high resolution even on a small screen. For this reason, the screen shows better color performance and get good image.
The traditional display is composed of many circuits, which need to consume a lot of power, and with the increasing volume, the power consumed by the internal circuit will certainly increase. In contrast, the power consumption of TFT LCD display is mainly consumed by its internal electrodes and driving IC, so the power consumption is much less than that of traditional displays.
