The bad point is a physical damage that the LCD screen cannot be 100% avoided in production and use. In most cases, it is generated during screen manufacturing, and impact or natural loss during use may also cause bright/bad spots. As long as one or more of the three primary colors that make up a single pixel are damaged, bright/bad points are generated, and both production and use may cause damage.

Some LCDs have a bad point that may be caused during use. Simply tell you some precautions when using it normally:
1, to minimize the possibility of direct exposure of the screen under strong light, in order to prevent the screen from being exposed to strong light, resulting in excessive temperature and accelerated aging;
2, LCD screen is one of the most vulnerable parts of the TV, do not remember to use the pen, key and other sharp objects on the screen to "point and point";
3. Keep the voltage power normal.
The above is just a few small methods when checking the LCD panel. There are still many ways to identify LCD panels. We have a newer and better way to tell you the first time. Here again, you should be reminded of your attention. You must make a good statement with the manufacturer when purchasing the LCD TV, so that your rights will not be harmed. Say so much, I hope you can buy a flat-panel TV that is really good.
