Abstract

The invention discloses a real-time detection method and device for display faults in a production line, and a storage medium, and the method comprises the steps of obtaining a display image, and enabling the background of the display image to comprise a pure-color background, a gradient-color background and a grid background; performing pure-color fault detection by utilizing the display image with the pure-color background; performing gradient color fault detection by using the display image with the gradient color background; and carrying out grid fault detection by utilizing the display image with the grid background. Display images (a pure color background, a gradient color background and a grid background) with different backgrounds are obtained respectively, and different faults ofthe display are detected.

Description

technical field [0001] The invention relates to the field of display detection, in particular to a real-time detection method, storage medium and device for display faults in a production line. Background technique [0002] Liquid crystal display technology has been widely used in the electronic information industry, and plays an important role in promoting the transformation of economic development mode, promoting the optimization and upgrading of industrial structure, and driving the development of high-tech. With the rapid development of microelectronic technology, liquid crystal display (LCD) is developing towards the direction of large screen, low power consumption, light and thin, and high resolution. [0003] Such a trend, while bringing many advantages such as high visual effects and portability, will also greatly increase the probability of various display defects in LCDs. For example, the cold cathode fluorescent lamp (Cold Cathode Fluorescent Lamp, CCFL) widely u...
