Automatic display screen defect detection system and method

Abstract

The invention discloses an automatic display screen defect detection system and method. The system comprises a camera obscura, a camera and an upper computer, wherein the camera is connected with theupper computer, and is used for shooting pictures of a display screen to be detected in the camera obscura under different color displays and outputting the pictures to the upper computer; the upper computer is used for processing the received pictures so as to judge whether the display screen to be detected has defects or not. Through the automatic display screen defect detection system and the automatic display screen defect detection method, defects of the display screen in different color interfaces can be rapidly and stably detected, so that the production speed is increased and the production labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of display screen defect detection, in particular to a display screen defect automatic detection system and method. Background technique [0002] Before the display screen leaves the factory, the manufacturer needs to conduct strict inspections on whether the display screen is defective. Taking the display screen of a laptop computer as an example, it is often judged whether there is a defect in the display screen by detecting the display status of the display screen in six screens of red, green, blue, white, gray, and black. At present, the traditional notebook computer production line detects the defects of notebook computer display screens by using human inspection. When the employees detect the defects of the display screen, they use the program to observe the bad phenomena that appear in the solid color screens of each color. Each color screen needs at least 10 The observation time is 15 seconds. In th...

At present, the traditional notebook computer production line detects the defects of notebook computer display screens by using human inspection. When inspecting display screen defects, employees use programs to observe the adverse phenomena that appear in the solid-color pictures of each color. Each color picture needs at least 10 The observation time is 15 seconds. In this way, it takes at least one to two minutes for each person to test a computer, and at least 6 to 8 people are required to test a production line to meet production needs.

The above-mentioned method of manually detecting defects on the display screen not only takes a long time, is inefficient, and has high labor costs, but also causes employees to observe the display screen for a long time, which will cause damage to the health of the employees, and secondly, the visual fatigue of the employees will easily miss some defective products, reducing the The yield rate of the factory may cause damage to the reputation of product quality
