Abstract

The invention discloses a display panel bad point detection system, which includes an image acquisition module, an image processing module, an image analysis module and a matching verification module; the image acquisition module is used to acquire display images of the display panel; Dividing the display image to obtain a display divided image, acquiring and combining pixel values ​​of the displayed divided image to obtain a divided pixel set; the image analysis module is used to analyze and calculate the displayed image according to the divided pixel set to obtain a display analysis set; The matching verification module is used to verify the dead pixels of the display panel according to the display analysis set; the present invention is used to solve the problem of inability to efficiently and accurately analyze the external pixels when the display panel is photographed to collect a solid-color image and analyzed in the existing solution. The difference between the attachment and the dead pixels of the display panel leads to the technical problem that the detection effect of the dead pixels of the display panel is not good.

Description

technical field [0001] The invention relates to the technical field of display panels, in particular to a detection system for dead pixels of a display panel. Background technique [0002] The dead point of the LCD screen is also called the absent point. It refers to the sub-pixels displayed on the LCD screen in black and white and the three primary colors of red, green and blue. Each point refers to a sub-pixel. Dead pixels can be roughly divided into two categories. Among them, dark dead pixels are "black spots" that cannot display content no matter how the screen display content changes, and the most annoying ones are the bright spots that always exist as long as the device is turned on. If the dead pixels are caused by technical factors, they cannot be repaired. But if it is caused by keeping a static picture for a long time, it is possible to use software repair or wipe to remove it. [0003] The invention patent with the publication number CN101715050A discloses a me...
