Problems solved by technology

[0002] With the rapid development of display panel technology, people's demand for large-size and high-resolution display panels is increasing day by day. Affected by the panel manufacturing process, large-size panels are more prone to mura defects than small and medium-sized panels, resulting in display panel Uneven brightness and uneven display screen will affect the yield rate of the display panel, so it is necessary to use demura technology to improve the display quality of the screen

Abstract

The invention relates to the technical field of display, in particular to a darkroom detection device and method, the darkroom detection device comprises a darkroom body, a bearing platform, a drivingmechanism, a shading plate and a detection assembly, the darkroom body is provided with a hollow cavity, and the side surface is provided with an opening part; the bearing platform is used for placing at least one to-be-detected piece; the driving mechanism is used for driving the bearing platform to move horizontally, so that the bearing platform penetrates through the opening part and is arranged inside the hollow cavity or outside the darkroom body; the shading plate is arranged at one end of the bearing platform and used for at least partially covering the opening part when the bearing platform is located in the hollow cavity; and the detection assembly is arranged in the hollow cavity and used for detecting the to-be-detected piece. According to the darkroom detection device, shakingof the darkroom detection device can be reduced, the step of adjusting the shading plate is omitted, and the detection accuracy of the to-be-detected piece is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a darkroom detection device and detection method. Background technique [0002] With the rapid development of display panel technology, people's demand for large-size and high-resolution display panels is increasing day by day. Affected by the panel manufacturing process, large-size panels are more prone to mura defects than small and medium-sized panels, resulting in display panel Uneven brightness and uneven display images will affect the yield rate of the display panel, so it is necessary to use demura technology to improve the display quality of the image. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a darkroom detection device and a detection method, which can improve the stability of the darkroom detection device. [0004] In order to solve the above technical problems, a technical solution adopted by the ...
