Embodiment approach

[0058] The processor 23 controls the panel under test 21 to display the structured light image, and receives confirmation information sent by the panel under test 21 . In one embodiment, the processor 23 may send a control command to the panel under test 21, and after receiving the control command, the panel under test 21 displays the structured light image based on the control command, and after displaying the structured light image, sends the control command to the processor 23. Confirm the information. In this embodiment, the panel under test 21 internally stores an encoding program containing preset encoding parameters, and the panel under test 21 can display the structured light image by directly invoking the encoding program after receiving the control instruction. The encoding parameters include at least one of background light intensity, fringe amplitude, initial phase, fringe width, fringe interval, fringe period, and phase interval. In another embodiment, the proces...

Abstract

The embodiment of the present invention discloses a detection method, which includes: controlling the panel to be tested to display a structured light image, and receiving confirmation information sent by the panel to be tested; wherein the confirmation information is used to indicate that the panel to be tested The structured light image has been displayed; controlling the detection device to capture the structured light image based on the confirmation information to obtain a target image; controlling the detection device to analyze the target image to determine whether there is a defect inside the panel to be tested . The embodiment of the invention also discloses a detection system and a computer storage medium.

Description

technical field [0001] The invention relates to the field of electronics and information technology, in particular to a detection method, system and computer storage medium. Background technique [0002] With the rapid development of display technology, defect detection of display panels in various manufacturing processes in the production process has become an indispensable process to ensure and improve the yield rate of panels. However, it is impossible to determine whether there is a defect inside the display panel in the related art. Contents of the invention [0003] In order to solve the above technical problems, the embodiments of the present invention expect to provide a detection method, system and computer storage medium to solve the problem in the related art that it is impossible to determine whether there is a defect inside the display panel. [0004] Technical scheme of the present invention is realized like this: [0005] A detection method, said method co...
