The development of the display industry has sprung up in recent years, with continuous development and progress, and new product categories. The application fields of tft LCD screens have become more and more extensive. Today I will give you a brief introduction about tft LCD screens. The display principle.
What is TFT LCD display?
tft lcd liquid crystal display is a classification of LCD liquid crystal module. TFT is the abbreviation of "ThinFilmTransistor", it is a thin film transistor type liquid crystal display, also known as "true color". TFT liquid crystal is equipped with a semiconductor switch for each pixel, and each pixel can be directly controlled by dot pulses. Each node is relatively independent and can be controlled continuously, which not only improves the response speed of the display screen, but also accurately controls the display color gradation, so the color of the TFT liquid crystal is more true.
The tft lcd liquid crystal display is an active matrix liquid crystal screen. It is a screen composed of thin film transistors. Each of its liquid crystal pixels is driven by thin film transistors, which can achieve high-speed, high-brightness, and high-contrast display screens. Information. Behind each pixel, there are four independent thin film transistors driving the pixel to emit colored light, which can display true color with 24bit color depth. In terms of resolution, the TFT LCD screen can reach up to UXGA (1600×1200).
The arrangement of TFT is memorable, so it will not return to its original state immediately after the current disappears, thereby improving the shortcomings of STN LCD screen flicker and blur, effectively improving the effect of LCD screen displaying dynamic images, and the ability to display static images More prominent.
