Image signal generation method and device with coordinate acquisition function

Abstract

The invention discloses an image signal generation method and device with a coordinate acquisition function, and relates to the technical field of display panel detection. The method includes the steps: S1) acquiring vertical line position indication signals and horizontal line position indication signals according to resolution ratio configuration information and (X, Y) coordinate configuration information; S2) acquiring cross line coordinate point information according to the vertical line position indication signals and the horizontal line position indication signals, and configuring RGB (red green blue) values of a cross line coordinate point; S3) correspondingly distributing the RGB values of the cross line coordinate point to RGB image data of links to obtain cross line image signals. The cross line image signals with real-time configurable color and center point coordinates are generated, an optical calibrator can be assisted in visually and rapidly acquiring coordinate information of defect points or defect areas of a display panel to be detected, and a laser repair machine can be assisted in improving the bright spot and dark spot repair efficiency of the display panel.

Description

technical field [0001] The invention relates to the technical field of display panel detection, in particular to an image signal generation method and device with a coordinate acquisition function. Background technique [0002] New display panels such as TFT-LCD and OLED have the advantages of high resolution, high brightness and no geometric deformation. At the same time, due to their small size, light weight and low power consumption, they are widely used in consumer electronics products that people use every day. , such as TV, computer, mobile phone, tablet, etc. The manufacturing process of new display panels such as TFT-LCD and OLED is relatively complicated, requiring clean rooms of class 100 or even class 10, nanometer-level dimensional control accuracy, and 6N-level (99.9999%) high-purity materials. Therefore, in the manufacturing process Inevitably, pixel structure abnormalities will be introduced, and serious display defects will be formed. According to the displ...

Problems solved by technology

At present, the focus of the optical calibrator on the defect position of the display panel mainly uses the method of moving the lens image on the display panel to search for the defect point. This focusing method has a large workload and low efficiency.
