Problems solved by technology

[0004] However, if the brightness uniformity of the display panel is poor due to its own defects (that is, there are obvious differences in the brightness in the display area, the local brightness is high, and the local brightness is low), then it will not be possible to accurately determine whether there is an over-bright or over-dark area. Dead pixels, resulting in reduced accuracy of detection results

Abstract

The embodiment of the invention discloses a detection system and a detection method of a display panel. The detection system comprises a first detection station, a second detection station and a server, in the detection stage of the display panel, a first display driving module is used for driving the display panel to display a first picture; a camera module is used for shooting the first picture to generate image information; an image processing module used for generating identification information according to the image information and sending the identification information to the server; the identification information comprises a bad name used for identifying the brightness information of the display panel; the server is used for receiving the identification information and sending the identification information to the second display driving module; a second display driving module is used for driving the display panel to display a second picture according to the identification information so as to perform display detection on the display panel according to the second picture; and the brightness uniformity of the second picture is greater than that of the first picture. The detection system can improve the accuracy of a detection result.

Description

technical field [0001] Embodiments of the present invention relate to a display panel detection technology, and in particular, to a display panel detection system and detection method. Background technique [0002] Display panels (such as organic light-emitting diode display panels) generally need to undergo quality inspection after the production is completed, so as to ensure that the manufactured products are high-quality products. [0003] When the display panel is performing display detection, the driver chip is usually not bound. Therefore, the detection line of the existing display panel first lights up the display panel through the display driver (module), and then judges whether the display panel is There are dead pixels (defective sub-pixels). If the luminance of each sub-pixel is within the standard luminance range (that is, the luminance of the entire display panel is relatively uniform), the position of the dead pixel can be determined more accurately. [0004]...
