Cause the laptop screen is blotchy and how to fix it

1. How to check the screen for bright spots

To check your screen for bright spots, you need images of the same color in different colors to see bright spots. If you do not know how to use images, you can download the images below and open them in full screen mode to see the light spots.

Usually, bright spots are Stuck Pixel points so they are usually white or show a color deviation from other Pixels!

2. Cause the screen is bright spots

The cause of the screen with bright spots usually appears due to the hardware, not the software, so do not try to find a way to fix the error by software. The error of the screen with bright spots, blobs is the color change shield that does not display the correct colors on the front matrix layer, causing them to display color error.

In addition, we have another case is the Stuck Pixel, which is also a hardware failure but the cause of them is different. Stuck Pixel, also known as stuck pixel, these pixels will still be bright, but they will light 'one way alone' even though the neighboring pixels show different colors. Usually, the Stuck Pixel is usually red, green, or green because this is the RGB color system on the screen.

3. The IPS screen's bright exposure characteristics

On current screen production technology, we have main panels such as: TN, IPS, VA. Among those panels, the IPS panel has a 'characteristic' that is exposed to the edge of the screen. This is not an error, it is an irreversible feature of the IPS display. Any IPS screen will suffer, it is just that they are more or less the same, with time exposure can get worse depending on the quality of production.

To see if the screen is exposed or not, just open the black image and you will see the corners of the screen have a stronger white light than the middle area.
