Due to the production defects of LCD panel, it is a common problem that bad points appear on LCD screen. LCD large screen consists of many points, each point is composed of RGB three primary color pixels constantly changing to form color and image. But when there is a problem with the pixels, so that the color can not change, it will form a bad point. Bad points are usually divided into several kinds, if it is a color highlight, it means that the pixels of the point are only stuck, we can repair such bad points. But if it's a black spot, it means that it's completely broken, even if it's repaired, it's ineffective. If the user who purchases a new product finds more bad points, it is better to find the manufacturer to exchange immediately. However, it should be noted that some manufacturers do not pay for a small number of bad points, such as some LCD monitors, if the bad points are less than three, they will not be replaced for users.
Marking pen squeezing method
Turn on the computer and monitor, and set the screen to a pure black screen (or other pure color that contrasts sharply with the color of the bad spot), so that the bright spot can be seen at a glance. Find a smooth pen cap, and gently squeeze it against the bright spot, then you can see the white light, if not, you can slightly increase the intensity. After about 5 to 10 times of extrusion, the liquid crystal flow inside the display screen can make the stuck pixels return to normal, and then make the highlights disappear.

Hot towel heating method
Using a pen cap to squeeze LCD screen may cause damage to the screen because the user exerts too much force. If the force is not accurate, we can also use a safer hot towel heating method to repair bright spots. Soak the towel in hot water and, if possible, heat the basin with fire until bubbles appear at the bottom. Take out the towel and put on the insulating gloves to twist it dry. Place the hot towel in the plastic bag on the bright screen, try to ensure that the heat is concentrated in the bright spot, hot compress for about 10 minutes, so that the liquid crystal inside the screen is heated and flowed, so that the bright spot disappears.

Software repair method
To the right of the main interface of the software is the repair function area. Before the repair, the display should be set to the best resolution and the screen saver program of Windows should be turned off. If you have more than one bright spot, you can first set the number of flashing points in the "Flash windows" option. At this time, there will be multiple flickering points on the screen, drag them to the position of the highlights with the mouse, and right-click to set their color.
Then choose the size of flicker point in "Flash size". There are 1 *1 and 5 *5 options. Then adjust the flicker period by "Flash interval". This time can not be too long. 25ms is more appropriate. Finally, click "Start" to fix it. It takes more than 20 minutes to run, and in most cases it takes 12 to 24 hours to take effect. This method can repair most of the highlights, and can also repair the highlights of LCD TV, notebook LCD screen, etc. If you suspect that downloading software is troublesome, you can visit www.jscreenfix.com, which can also fix highlights in the browser window.
