First, the display quality is high

Since each point of the LCD displays the same color and brightness after receiving the signal, it does not need to be refreshed continuously, unlike the CRT display (CRT). As a result, LCD displays are high quality and will never flicker and minimize eye strain.

Two. No electromagnetic radiation

The traditional display material is phosphor, and displayed by the electron beam impinging phosphor, electron beam in the hit moment between the phosphor will produce electromagnetic radiation strong, although there are many display products processing more effective in dealing with the radiation problem, the amount of radiation to minimize as much as possible but, it is difficult to completely eliminate. In contrast, liquid crystal displays have a natural advantage in preventing radiation because it does not contain radiation at all. In the prevention of electromagnetic wave, the liquid crystal display also has its own unique advantages, it adopts the strict sealing technology will come from the driving circuit of a electromagnetic wave closed in the display, and display the need to heat the ordinary, must keep the circuit inside the contact with air, so that the internal circuit generated by electromagnetic wave it is a lot to "leak".

Three, large visual area

For a display of the same size, the visual area of a liquid crystal display is greater. The visual area of a liquid crystal display is the same as its diagonal size. The cathode ray tube display has an inch frame around the front panel of the picture tube and cannot be used for display.

Four, a wide range of applications

The original LCD monitor, because it was unable to display delicate characters, was usually applied to electronic watches and calculators. With the continuous development of liquid crystal display technology and progress, character display also began the delicate, support basic color display, and gradually used in LCD TV, camera LCD, handheld game machine. And then the DSTN and TFT has been made into a liquid crystal display device in the computer, DSTN LCD screen for notebook computer early; TFT is used in notebook computer (now the majority of notebook computer using TFT display), and is used in mainstream desktop display.

Five, the picture effect is good

Compared with the traditional display, the LCD displays the flat glass board from the beginning. The display is flat right angle, which gives people a refreshing feeling. And the liquid crystal display is easier to achieve high resolution in a small area on the screen, for example, 17 inch LCD can achieve a good 1280 x 1024 and 1280 x 1024 resolution, the use of more than 18 inches CRT display resolution is usually on the picture is not entirely satisfactory.

Six 、 digital interface

The liquid crystal display is digital, unlike the CRT display with analog interface. That is to say, using LCDs, video cards no longer need to convert digital signals into analog signals and then output them as usual. In theory, this will make color and positioning more accurate and perfect.

Seven, "body" compact symmetry

The traditional cathode ray tube display always drags a heavy ray tube behind it. Liquid crystal displays have broken this limit, giving people a whole new feeling. Conventional displays emit electron beams through the electronic gun to the screen, so the tube neck of the picture tube cannot be made very short, and the volume of the display is bound to increase as the screen increases. The liquid crystal display screen through the electrode control state of liquid crystal molecules to achieve that, even if the screen is increased, increasing the volume of it is not directly proportional to, and in the same weight than traditional display area of a display much lighter.

Eight, power consumption is small

The display consists of many traditional circuit, the circuit drives the cathode ray tube, need large power consumption, and with the increasing of volume, power consumption of the internal circuit certainly will increase. In contrast, the power consumption of liquid crystal display is mainly consumed in its internal electrode and drive IC, so the power consumption is much smaller than the traditional display.
