Advantage of LCD

Crystal TV and traditional CRT and plasma compared to a major advantage or power, liquid crystal with only half of the size of the power consumption of CRT, is much lower than the plasma.

Compared with the traditional CRT LCD is also reflected in the environmental performance, this is because the LCD has no high voltage components like CRT, so it may not appear as X ray high voltage lead to exceed the standard, so the radiation indicators generally lower than CRT.

Because the CRT display is the electromagnetic field generated by a deflection coil to control the electron beam, but due to the electron beam on the screen and not absolute positioning, so CRT display usually there are different degrees of geometric distortion, linear distortion. The liquid crystal display because of its principle will not appear any geometric distortion, linear distortion, which is also a big advantage.

Liquid crystal display large visual area: General CRT display in the display, the display screen will have some black edges around the visual screen; and the LCD screen will not have these problems. Full visual screen. For example: 13 inch LCD is equivalent to a 15 inch CRT display. High resolution \ fine quality, than CRT and plasma have a great advantage.

Lightweight portable

Because of the traditional use of CRT, the electron beam must be transmitted to the screen through the electron gun, so the tube neck of the kinescope can not be made very short. The liquid crystal display screen through the electrode control state of liquid crystal molecules to achieve that, even if the screen is increased, increasing its volume is not proportional to (only increase in size without increasing the thickness so as to provide a wall function, many products can allow users to save more space), and in weight than the same area of the traditional display display much less, the weight is about the traditional LCD TV 1/3 tv.

Resolution and resolution

Liquid crystal display from the beginning of the use of pure flat glass plate, its plane right angle display effect is much better than the traditional display. But in the resolution, the display on the liquid crystal theory can provide higher resolution, but the actual display much less (there is an optimal resolution of the problem), while the LCD TV can overcome the scan line jitter and flicker, but because of the gap of the LC coarse, will cause the image to watch the effect such as grid like. So the best resolution of the LCD screen can reach 1024X768 (enough). The traditional display in the display card to support the best display effect.

Green

There is no liquid crystal display at all, and only a small amount of electromagnetic waves from the drive circuit, as long as the shell can be strictly sealed to exclude electromagnetic leakage. So the LCD monitor is called a cold monitor or an environmental monitor. LCD TV screen flicker does not exist, it is not easy to cause visual fatigue.

Low power consumption

In accordance with industry standards, the use of time for 4.5 hours per day of electricity consumption conversion, with a 30 inch LCD TV instead of a 32 inch CRT TV, each year can save electricity by 71 kilowatts.
