Active detection method and system for damage to display screen of electronic equipment

Abstract

The present invention provides an active detection method and system for damage to the display screen of an electronic device, including a detected subsystem located in the electronic device and an active detection subsystem installed on the detection device; the active detection subsystem includes a machine vision image acquisition module, Detection command sending module, anti-counterfeiting time-sensitive coding pattern discrimination module, positive-phase standard anti-counterfeiting time-sensitive coding pattern generation module; the detected subsystem includes a standby power management module, positive-phase anti-counterfeiting time-sensitive coding pattern generation module and reverse-phase anti-counterfeiting timeliness Sexually encoded pattern generation module. The advantages are: by notifying the electronic equipment to generate and display the anti-counterfeit time-sensitive code pattern, and through the anti-counterfeit time-sensitive code pattern detection and optical image machine vision appearance defect detection process, the appearance and display module of the leased or shared electronic equipment can be effectively detected In this way, it can effectively judge the situation that cannot be judged by traditional optical vision inspection AOI, such as occlusion and fraud.

Description

technical field [0001] The invention belongs to the technical field of damage detection of display screens of electronic equipment, and in particular relates to an active detection method and system for damage of display screens of electronic equipment. Background technique [0002] Electronic devices, such as mobile communication terminals (mobile phones), PDAs, mobile computers, tablet computers and other devices, generally have display screens. Display screens generally include EPD electronic ink screen (Eink Paper Display), LCD liquid crystal display, OLED organic light-emitting display, PDP plasma display, quantum light-emitting display, MicroLED micro-LED display and other methods. The display screen structure is generally composed of all or part of the following: cover glass, touch sensor layer, front panel, back panel, backlight module, etc., which are high-value, fragile, and easily damaged parts, and are easily damaged by water, moisture, and sharp objects. Scorin...

AI Technical Summary

Problems solved by technology

Especially for the first type of display module internal fault damage, but the cover glass is intact, the traditional machine vision image system based on optical image detection cannot effectively distinguish due to the lack of effective detection methods.
