Fix laptop LCD screen bad point

Because of the particularity of the notebook LCD screen, LCD panel in the factory or in the use of the process is very easy to have a bad situation, once encountered them, if the manufacturers have a better policy to protect the point, can be replaced by distributors or return to plant repair, but if within the scope of the manufacturer's provisions (generally under 3 points below), Then users can only think of themselves as unlucky.

From the principle point of view, the bad points are divided into bright and dead two species, it is the difference between the bright spot is due to the liquid crystal flow in the display of the LCD is always a single color, such as red, green or blue, the dead point is displayed as the pixel black, because the liquid crystal can not flow, dead point can not be repaired. In fact, although the highlight is a liquid crystal display on the most headache small flaws, but sometimes can be repaired by some means.

Undead Pixel is a small tool that fixes the bright spot of liquid crystal display, its principle is to use high frequency random alternating switch red, green, blue three kinds of color, stimulate bright spot disappears. The software is very small, directly click the only UDPixel.exe file to run the interface, its method is very simple.

Undead pixel interface is divided into about two functional areas, the left of the "Dead Pixel locator" area for the detection of display highlights function, users directly click on a different color bar can be set screen red, green, blue, white, black and other colors of the background to find the location of the bright spots, Of course, for some special color highlights, users can also customize the setting of different color backgrounds. If you click on the "Run cycle" button, you can automatically switch to different backgrounds.

The right side of the undead pixel interface is to repair the ribbon, which needs to be set to the best resolution before fixing it. If you have multiple highlights, you can set the number of flashing points in the Flash Windows option first. At this point there will be multiple blinking points on the screen, drag them to the spot with the mouse, and click Right to set their color (Figure 2).

Then in "Flash size", select the size of the blinking point, with 1x1 and 5x5 two options. Then through the "flash interval" to adjust the flashing cycle, can be adjusted from 3ms to 80ms, this time can not be too long, 25ms more appropriate. Finally click "Start" to start the repair. So undead pixel through the bright spot at the high frequency of constantly flashing a variety of colors to activate the broken bright spot.

I personally feel that the running time needs to be more than 20 minutes, most cases will take 12-24 hours before it takes effect. This method can repair most of the highlights, the LCD TV, notebook LCD screen and other bright spots also have repair, but may not have any effect. And from the operating principle of software, there is no impact on the monitor, there are bright spots friends may wish to try.
