Problems solved by technology

However, the above re-judgment method has at least the following problems: (1) Due to the laser projection distance and direction positioning, it is easy to have a large deviation between the projected position and the actual defective position, which will interfere with the operator's re-judgment operation; The necessary presence of the front polarizing glass plate in the detection process equipment, the actual projected light spot reflection and scattering are very strong, and it is almost impossible to actually observe the effective projected light spot
(3) This method can only mark point defects, and cannot effectively prompt operators for other types of defects, which has certain limitations

Abstract

The invention provides a method and system for examining bad coordinate positions in a display panel. The method comprises the following steps: obtaining a bad coordinate position of a display panel to be detected; according to the obtained bad coordinate position, generating a simulated coordinate position of a simulated display panel; and displaying the simulated coordinate position in the simulated display panel so as to project the bad coordinate position of the panel to be detected onto the simulated display panel. According to the provided method, the coordinate position of the display panel is accurately projected onto the simulated display panel; related personnel can conveniently carry out judgment again according to the coordination position on the simulated display panel, the bad coordinate position of the display panel can be precisely positioned, and the efficiency on repairing a bad display panel is improved.

Description

technical field [0001] The invention relates to the technical field of display device detection, in particular to a method and system for verifying bad coordinate positions in a display panel. Background technique [0002] At present, during the production process of display panels, due to various uncontrollable factors, some defective display panels may appear, which will bring losses to the production of display panels. But not all of these defective display panels will be scrapped, and some specific points, lines and other defects can be repaired by means of maintenance. [0003] In the process of repairing a defective display panel, it is necessary to accurately calibrate the specific coordinate position of the defect on the display panel. At present, the measurement method of the signal generator can be used to determine the coordinate position of the defect in the display panel, and then, through manual re-judgment. The poor coordinate position of the display panel is...
