Traditional CRT displays have been developed for decades, and their technical structural principles have limited their further development. Several major shortcomings inherent in vacuum cathode ray tubes have made it increasingly difficult for CRT displays to adapt to the further improvement of consumer requirements for displays. At this time, flat-panel display devices have emerged. Among them, the most likely position to replace CRT displays in the PC display terminal monopoly position is LCD Monitor. So what are the advantages of LCD screens? Sinda Display will introduce the advantages of LCD screen!

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

The display principle of the liquid crystal display is to restore the picture by twisting the deflection angle of the liquid crystal molecules in the liquid crystal pixels to achieve the background picture. There is no ultra-high-voltage components inside the CRT, so that the x-rays are not exceeded due to high voltage. In addition, the structure of the machine is simple, modular, and the high integration of the chip is sufficient to minimize the electromagnetic radiation generated during the circuit operation. This design directly reduces the power consumption of the circuit, and the heat generation is very small. Although the liquid crystal display may generate slight electromagnetic radiation during operation, it can be easily solved by the shielding circuit. CRT monitors must not drill holes in the shield to cause radiation leakage due to heat dissipation.

2. Slim and lightweight

It was the advent of liquid crystal displays that made the invention of portable computers possible. Similarly, although a desktop LCD monitor is larger in size and weight than a laptop computer, it's a shame compared to a clunky and heavy CRT monitor. Compared with a 15-inch monitor, the depth of a CRT monitor is generally close to 50 cm, while the latest white shark's latest NF-1500MA LCD monitor is less than 5 cm deep! With the change of consumption perspective and living environment, people have higher and higher requirements for the volume and weight of household appliances. With its inherent thinness and lightness, liquid crystal displays have become the most likely display devices to break the monopoly of CRT displays.

3. Accurately restore images

The liquid crystal display uses a direct digital addressing display method. It can convert the video signal output from the graphics card through AD conversion, and directly correspond to the liquid crystal on the screen according to the "address" signal in the signal level. Displayed in pixels. The CRT monitor relies on the electromagnetic field generated by the deflection coil 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 the geomagnetism, the absolute positioning of the electron beam on the screen cannot be achieved. Therefore, the geometric distortion and linear distortion of the CRT display are prone to phenomena that cannot be completely eliminated. This is not possible with LCD displays. The LCD monitor can perfectly display the picture on the screen without any geometric distortion and linear distortion.

4. Sharp display characters

The picture is stable and not flickering. The unique display principle of the liquid crystal display determines that each pixel on the screen emits light uniformly, and the three primary color pixels of red, green, and blue are closely arranged. The video signal is sent directly to the back of the pixel to drive the pixel to emit light, so there is no inherent convergence of traditional CRT displays As well as focusing on the ills of badness. Therefore, the text display effect on LCD monitors is vastly different from traditional CRT monitors. The fonts of LCD monitors are very sharp, and there is no such phenomenon as blurred fonts and font panning when CRT monitors display text. In addition, since the liquid crystal display always emits light after being powered on, the backlight works at high frequencies, and the display image is stable without flickering, which is conducive to using the computer for a long time. CRT displays rely on the electron beam to repeatedly hit the phosphor to achieve light emission, which will cause the brightness to flicker periodically. It is easy to cause discomfort to the human eye after prolonged use.

5. Easy screen adjustment

The direct addressing display mode of the liquid crystal display makes the screen adjustment of the liquid crystal display not need too much geometric adjustment and linear adjustment and position adjustment of the display content. The LCD monitor can easily adjust the screen to the best position automatically after calculating through the chip. You only need to press the "Auto" button to complete this step. Eliminates the cumbersome adjustment of CRT monitors. You only need to manually adjust the brightness and contrast of the screen to make the machine work at its best.
