Advantages of LCD screen

2022-09-24
The application of LCD liquid crystal screen is multi-faceted. The LCD screen produced by Dongguan Yijia Electronics Co., Ltd. is mainly used in medical, computer, remote control and other electronic product industries. Then LCD liquid crystal screen is used in comparison with CRT display. What are the advantages? Let me explain to you below.

1. Zero radiation, low energy consumption, small heat dissipation

The display principle of the LCD liquid crystal screen is to restore the picture by twisting the deflection angle of the liquid crystal molecules in the liquid crystal pixels to restore the background light. Moreover, the machine structure circuit is simple, the modularization and the high integration of the chip are enough to reduce the electromagnetic radiation generated when the circuit is working to the lowest level. Such a design directly reduces the power consumption of the circuit and generates very little heat. Although the LCD liquid crystal screen may generate slight electromagnetic radiation during operation, it can be easily solved by shielding the circuit. For CRT monitors, due to the consideration of heat dissipation, it is not allowed to drill holes on the shielding cover to cause radiation leakage.

2. Slim and lightweight

It was the emergence of the LCD screen that made the invention of the portable computer possible. Similarly, although the desktop LCD screen is larger in volume and weight than that of a laptop computer, it is nothing compared to the bulky and heavy CRT display. Compared with a 15-inch monitor, the depth of a CRT monitor is generally close to 50 cm, while the depth of the new LCD screen NF-1500MA of Jaws Z is less than 5 cm! With the change of consumption viewpoint and living environment, people have higher and higher requirements on the volume and weight of household electrical appliances. With its inherent advantages of being thin and light, LCD liquid crystal screen has become the most likely display device to break the monopoly of CRT displays.

3. Display characters sharp

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.

4. Accurately restore images

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.
