LCD characteristics

superiority

1. Compared with traditional CRT and plasma, LCD TV still saves electricity. The power consumption of LCD TV is only half that of CRT of the same size, far lower than that of plasma.

2. Compared with the traditional CRT, liquid crystal also shows some performance in environmental protection. This is because there is no high-voltage component like CRT in LCD, so the X-rays caused by high voltage will not exceed the standard, so its radiation index is generally lower than CRT.

3. Because CRT displays control the electron beam through the electromagnetic field generated by the deflection coil, and because the electron beam cannot be positioned absolutely on the screen, CRT displays often have different degrees of geometric distortion and linear distortion. The liquid crystal display (LCD) will not have any geometric distortion and linear distortion due to principle problems, which is also a big advantage.

4. The LCD display has a large visual area: when a CRT display is developed, there will be some black edges around the display screen to occupy the visual picture; The LCD screen will not have these problems. This is a clear picture. For example, 13 inch LCD is equivalent to 15 inch CRT. High resolution \ high image quality, which has great advantages over CRT and plasma.

Maintenance skills

1. Try not to let the LCD TV work for a long time or display the same picture continuously. Because the screen of LCD TV is displayed by LCD pixels to form a picture, LCD TV will overheat and burn out if it works for a long time or displays the same picture all the time.

2. Therefore, when users are not watching TV, they should turn off the display or turn down the brightness of the display in time. Users should try to avoid pressing the pause button while enjoying the CD to keep the picture displayed.

3. Avoid hitting the screen. Because the LCD screen is very fragile, in order to avoid strong impact and vibration, users remind children not to practice impactful activities on TV.

4. Pay attention to the dryness of TV. Television has a high technical content. Although you can work in a humid environment, you can only "work as usual" but not "work normally". Moisture does great harm to TV sets. Therefore, even if users don't watch TV for a long time, it's best to turn on the power regularly, so that the heat generated when the monitor works can drive out the moisture in the machine.

5. Clean the screen correctly. If the screen is dirty, it is best to use a professional cleaning agent and gently wipe it with a soft cloth dipped in a little water, but the amount of water should not be too large, because the water enters the LCD and causes the screen to be short-circuited.

6. If there is fog on the LCD screen, wipe it gently with a soft cloth in time, and then turn on the power. If moisture has entered the LCD, it must be placed in a dry and warm place to allow the moisture to fully evaporate.

7. Even if the power supply is not connected, do not disassemble the LCD by yourself. Due to the long turn-off time, the CFL converter in the TV backlight assembly may still have a high voltage of about 1000 volts. 1000 volts can also cause serious personal injury. In addition, even if the user does not get an electric shock, the wrong operation will cause temporary or even permanent damage to the display screen.
