Laptop screen has bright spots

Will a bright spot on a laptop display expand over time?

No. In fact, the irreparable physical pixels on the LCD panel are dead pixels, and dead pixels It is divided into two types: bright spots and dark spots. Bright spots refer to pixels that still glow when the screen displays black, while dark spots refer to pixels that do not display color. Since their presence will affect the display effect of the picture, the fewer dead pixels, the better.

If it is indeed a bright spot, it will not increase. The bright spot is a constantly bright spot caused by a short circuit inside the glass. It is caused by the glass processing process and is a stable defect. However, there are many LCD defects that appear to be bright spots but are not.

If the screen has no dead pixels when it leaves the factory, dead pixels will appear in the future, but the probability is very small. If there are more than three dead pixels in a short period of time, then the screen is very poor. It is best to repair or replace it within the warranty period.

No, but if you just bought it, you should take it back and exchange it. Anyway, a monitor with dead pixels looks awkward, right? Those are called dead pixels. When buying, you should ask him to guarantee that there are no dead pixels. If you are using a Windows 7 system, there is indeed a bright spot in the upper left corner, but this is normal.

Highlights are due to the poor flow of liquid crystal inside the display screen, which causes some pixels to always maintain a single color, such as red, green or blue; in fact, bright spots are the most troublesome small flaw on LCD monitors , but sometimes it can be repaired by certain means.

This is a defective pixel of the screen. There are bright spots and dark spots. Yours is a bright spot. A typical computer has millions of pixels, and the probability of a perfect screen without any dead pixels is about 80%. It is allowed to leave the factory with less than three dead pixels.

Allowed. Because a screen is composed of millions of transistors, if one of them has a problem, bright spots, dark spots, color spots, etc. will appear, so the probability of occurrence is very high. Generally speaking, laptops from larger brands are less likely to have this problem.

The screen may have bad pixels, which may be because you didn’t notice it when you bought it, or it may appear later. If there are more than three of them, the screen is very bad. A intact LCD screen will generally not have dead pixels during daily use.

During this time, you can see whether the screen still has this phenomenon). In this case, it may be a problem with the monitor.

Question 2: There is no way to repair the bright spots and dead pixels on the laptop monitor. Of course, it is actually impossible to completely physically repair the bright spots. You can only repair the bright spots until they are not obvious or basically invisible. The principle is It is a high-frequency random switching of red, green and blue colors, and the bright spots disappear, which makes sense physically.
