The problem of laptop screen bad spots has been deeply afflicted by obsessive-compulsive patients. They can't eat or sleep and wonder how to wipe out the bad spots of the screen all day long. Today we took the Thinkpad T530 screen as an example to explain how it was broken. Deal with this issue.

       In general, most of the dead pixels are caused by the fact that the current LCD manufacturing process is not yet mature. For this reason, the author has found a way to solve this problem.

Determine the problem first and check whether the bad point on the notebook screen is a "card point" or a "dead point." "Card points" are always colored, and "dead spots" are always white (TN-type panels) or always black. Try to determine what kind of problem it is.

       If it is a "dead point" problem, the safest way is to honor your warranty terms and send it back to the manufacturer for repair.

       If you have already passed the warranty period, you can try the following methods. However, it should be used with caution because the following methods are mainly aimed at the “card point” problem.

This method is to press Dafa, first open the computer and LCD screen.

       Open the black picture so that the card point is highlighted. It's important to note that you're going to open a black image instead of a blank area because you need to highlight the dead pixel area with a large black background.

To find a small thing, the head is blunt and narrow. If you have a marker pen with a pen cap, or a very blunt pencil, plastic pen, or the end of a makeup brush can be.

       Before you read down on the warning section, remember that rubbing the screen hard may cause the situation to deteriorate. Use the rounded end of the object to gently tap the card point.

       Do not shoot too hard at first, as long as you can see a small white floodlight area below the contact point. If you can't see the white floodlight area, you can't knock it hard enough to make a little more effort.
