Today's monitors, notebooks, tablets, mobile phones, and digital cameras basically use LCD screens. However, the liquid crystal display is very fragile. It may take a long time or if it is touched, it may hurt it. Sometimes when we stare at the screen, we will find that there are some small dots on it, that is, we often Said the bad point. Although fewer dead pixels do not affect the image display, it always looks more unsightly, so let's use a few tips to fix these small bad points. Causes of Bad Points Due to the production defects of the liquid crystal panel, it is a common problem to appear a dead pixel on the screen of the liquid crystal display. The liquid crystal screen is composed of a plurality of dots, and each dot is constantly changed by the RGB three primary color pixels to form a color and an image. However, when there is a problem with the pixel and the color cannot be changed, a bad point is formed. There are usually several bad points. If it is a color highlight, it means that the pixel at that point is just stuck. We can fix this kind of dead point. But if it is a black dark spot, it means that the point is completely broken, even if the repair is invalid. If the user who purchased the product has found more dead pixels, it is best to find the manufacturer 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 point is less than 3, it will not be exchanged for users. Marker Squeeze Open the computer and monitor and set the screen display to a pure black screen (or other solid color that contrasts with the color of the dead pixels) so that the highlights can be seen at a glance. Find the cap is a sleek pen, squeeze its cap against the highlights, then you can see the white light, if not, you can increase the strength a little. After about 5 to 10 squeezing, the liquid crystal inside the display screen can make the stuck pixels return to normal, and the bright spots disappear. The hot towel heating method uses a cap to squeeze the LCD screen, which may cause damage to the screen due to the user's excessive force. If the power is not accurate, we can also use the safer hot towel heating method to fix the highlights. Soak the towel in hot water and, if possible, heat the basin of the water with a fire until bubbles appear at the bottom. Remove the towel and wring it with insulated gloves. Place the hot towel in the plastic bag on the screen with bright spots, try to ensure that the heat is concentrated at the bright spot, and apply heat for about 10 minutes, so that the liquid crystal inside the display screen is heated to flow, so that the bright spots disappear. Software repair method Relatively speaking, the safest and most convenient way to fix the highlights is to use software.
