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

LCD display principle is through the reversal of the liquid crystal molecules in the LCD pixel deflection angle to the background light and restore the picture, there is no internal ultra-high voltage components like CRT, not to appear due to high pressure caused by the x-ray overload. And the machine structure circuit is simple, modular and highly integrated chip is enough to minimize the electromagnetic radiation generated by the circuit work. This design directly reduces the power consumption of the circuit, heat generation is also very small. LCD screen may produce a slight electromagnetic radiation when working, but it is easy to solve through the shielding circuit. CRT monitor due to the consideration of heat dissipation, shall not drill holes in the shield resulting in the leakage of radiation.

2. Thin and lightweight

It is the emergence of LCD screen, so that the invention of the laptop computer is possible. Similarly, the table LCD screen, although in the volume and weight than the laptop computer are a little larger, but, compared to the stupid and heavy CRT monitor is a small witch. Compared to the 15-inch monitor, CRT monitor depth is generally close to 50 cm, while the depth of the latest LCD screen NF-1500MA launched by Jaws is less than 5 cm! With the consumer point of view and the change of living environment, people on the volume of household appliances and weight requirements are increasingly high. LCD screen with its slim and light natural advantages to become the most likely to break the monopoly of the CRT display display devices.

3. Sharp display characters

The screen is stable and does not flicker. LCD's unique display principle determines the uniformity of light emitted by each pixel on its screen, and the red, green and blue pixels are closely aligned, and the video signal is sent directly to the pixel behind the pixel to drive the pixel light, so there is no traditional CRT display inherent convergence and poor focus drawbacks. Therefore, the text display effect on the LCD screen is very different from the traditional CRT display, and the font of the LCD screen is very sharp, no CRT display text blurring, font coloring and other phenomena. Moreover, because the LCD screen has been in the light after the power, the backlight work in high frequency, display screen stability and not flicker, conducive to the use of computers for a long time. CRT monitor is to rely on the electron beam repeatedly hit the phosphor to achieve light, which will lead to periodic flicker of brightness. After a long time use is easy to cause discomfort to the human eye.

4. Accurate restoration of images

LCD screen is a direct digital addressing display, it can be the video signal output from the graphics card after AD conversion, according to the signal level in the "address" signal, the video signal directly corresponding to the LCD pixels on the screen. The CRT display relies on the deflection coil to generate electromagnetic field to control the electron beam on the screen to periodically scan to achieve the purpose of displaying images. Since the trajectory of the electron beam is easily affected by the ambient magnetic field or geomagnetism, it is impossible to achieve absolute positioning of the electron beam on the screen. Therefore, CRT displays are prone to geometric distortion, linear distortion and other phenomena that cannot be eliminated at all. The LCD screen can present the picture on the screen perfectly without any geometric distortion or linear distortion.
