What is the quality of the LED backlight LCD TV?

LED backlight LCD TV is really good,I saw a friend at home,It uses an IPS hard screen panel,Natural color,Delicate picture quality,My friend said that this kind of panel has been recognized by relevant institutions,You can go to Gome home appliances to see。

The heat dissipation performance of the IPS hard screen panel is not good. The service life is relatively short,The problem of poor color display effect of the current soft screen has been solved,So,It's a good point to buy a TV or choose a soft screen,IPS hard screen panel is actually LG's panel,Soft screen is Samsung's,Samsung's screen is better than LG,Samsung's is better,The difference between LED TV and ordinary LCD TV is that the backlight is different,We know,The liquid crystal itself does not emit light,Light is needed to illuminate,Simply put, the arrangement of the lights behind the LCD panel is different, This makes LEDs display better, last longer and are more energy-efficient, and also thinner. LED TVs are recommended to buy Changhong and Hisense.

But Changhong's technology is relatively better than Hisense,If you want to buy high-endLED, it's better than Changhong。 The landlord adds points

I think Samsung's is pretty good, LZ can pay attention to it.

Using IPS hard screen panel, high definition, fast response, you can watch movies and play games. Entertainment and network functions have also been added, and the functions are relatively complete.

1. When the backlight turns off when the LCD screen turns on at the moment of AC start-up, at this time, the control functions of the sound, remote control and panel buttons are normal. This phenomenon is caused by the protection of the backlight circuit, and the reason is mostly the abnormal power supply of the backlight booster board. 2. An open circuit of a backlight tube of LED TV (commonly referred to as circuit protection caused by the soldering of the lamp socket on the backlight booster board or the socket is not plugged in tightly).

3. A lamp in the LED TV backlight is broken.

Suggested workaround:

1. If the backlight is damaged, there is no light, and the TV will not appear black on the surface of the song, calm down first, carefully observe the LCD screen, if you see a faint image display on the LCD screen, it indicates that the relevant circuit of the backfield light-carrying lamp is broken.

2. If the backlight circuit is intact and the display circuit part is faulty, then you will see that there is a bright white light emitted behind the LCD screen, which should be a backlight circuit problem or power supply problem, and it is most likely a short circuit or open circuit inside the boost coil.

3. First of all, power on the LCD screen separately, observe the fault phenomenon, whether there is any of the above situations, reconnect the input signal line, turn on the TV, observe whether the power indicator of the TV is bright, whether the LCD screen has an image display, if the pattern is very light and not too obvious, the backlight is damaged, and a new backlight needs to be replaced.

4. If the pattern you see is yellow, it should be the aging of the backlight, you can adjust the color temperature and white balance, if you can't meet the requirements after debugging, please replace the lamp.
