The screen is stable and does not flicker. The unique display principle of Liquid Crystal Display determines that each pixel on the screen emits evenly, and the three primary color pixels of red, green and blue are closely arranged, and the video signal is directly sent to the back of the pixel to drive the pixel to emit light, so there is no inherent convergence of traditional CRT displays. And the ills of poor focus. Therefore, the text display effect on the LCD liquid crystal screen is very different from that of the traditional CRT display. The fonts on the LCD screen are very sharp, and there is absolutely no font blurring and font flooding that appear when the CRT monitor displays text. Moreover, since the LCD screen keeps emitting light after being powered on, and the backlight works at high frequency, the display screen is stable and does not flicker, which is conducive to using the computer for a long time. The CRT display relies on the electron beam to repeatedly hit the phosphor to emit light, which will cause the brightness to flicker periodically. It is easy to cause discomfort to the human eyes after prolonged use.
The LCD liquid crystal screen adopts the display method of direct digital addressing. It can directly convert the video signal output from the graphics card to the one-to-one correspondence of the video signal on the screen according to the "address" signal in the signal level after AD conversion. displayed on the LCD pixel. The CRT display relies on the deflection coil to generate an electromagnetic field to control the periodic scanning of the electron beam on the screen to achieve the purpose of displaying images. Since the trajectory of the electron beam is easily affected by the environmental magnetic field or geomagnetism, the absolute positioning of the electron beam on the screen cannot be achieved. Therefore, the CRT display is prone to the phenomenon of geometric distortion and linear distortion of the picture that cannot be fundamentally eliminated. The LCD liquid crystal screen does not exist this possibility. The LCD liquid crystal screen can perfectly present the picture on the screen without any geometric distortion and linear distortion.
We focus on products in the field of optoelectronics, mainly selling Liquid Crystal Display, Liquid Crystal Display Module, Reflecting Liquid Crystal Display. If you need to consult us, if you want to know more, you can check our website, we also have Semi-transparent Liquid Crystal Display and Liquid Crystal Display For Clock on sale.
