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

Abstract

The invention provides an active detection method and an active detection system for a display screen damage of electronic equipment. The active detection system comprises a detected subsystem arranged in the electronic equipment and an active detection subsystem installed on detection equipment, wherein the active detection subsystem comprises a machine vision image acquisition module, a detection instruction transmitting module, an anti-counterfeiting timeliness coding pattern discriminating module, and a positive phase standard anti-counterfeiting timeliness coding pattern generating module; and the detected subsystem comprises a standby power supply management module, a positive phase anti-counterfeiting timeliness coding pattern generating module and an inverse phase anti-counterfeiting timeliness coding pattern generating module. The active detection method and the active detection system have the advantages of being capable of effectively detecting damage situations of appearance and display screen modules of rented or shared electronic equipment through notifying the electronic equipment to generate and display an anti-counterfeiting timeliness coding pattern through the anti-counterfeiting timeliness coding pattern detection and optical image machine vision appearance defect detection processes, thereby being capable of effectively discriminating the situations that the traditional optical vision detection AOI cannot discriminate such as license plate blocking, forging and the like.

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...

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.
