Abstract

The invention discloses a display detection method and system. The method includes the following steps of controlling the to-be-tested display to display a preset test picture; using the image acquisition device for acquiring a preset test picture displayed by the display to be tested so as to acquire a detection image; obtaining a to-be-corrected region from the detection image based on the plurality of boundaries corresponding to the preset test picture and detected from the detection image; geometrically deforming the to-be-corrected area to obtain the detection area and geometric deformation parameters of the detection area; judging whether the to-be-detected display is normal or not based on the pixel characteristic value in the other detection area obtained according to the geometric deformation parameter.

Description

technical field

[0001] The invention relates to a display detection method and system, and in particular to a display detection method and system capable of confirming whether the display screen of the display is normal. Background technique

[0002] In a traditional display production line, manufactured displays are inspected before shipment to ensure that each display is functioning normally. The traditional display testing method is to control the display to display various test pictures, and then let the inspector visually check whether these test pictures conform to the preset normal pictures. For example, it is judged whether the display being tested is a good product by observing whether the display correctly displays black, white, red, green, blue, gray scale, and color scale test images with human eyes. Once the display shows a defective image different from the preset test image, it can be determined that the display under inspection is a defective product with ab...
