Screen module, electronic equipment and micro-crack detection method for screen module

Abstract

The invention relates to the electronic technology field and discloses a screen module, electronic equipment and a micro-crack detection method for the screen module. The screen module comprises a glass substrate, a touch detection layer, a screen driving chip, N detection wires, N connection pins and N detection units, wherein the touch detection layer is laid on the glass substrate, the N detection units are arranged in the screen driving chip, the N detection wire and the N connection pins are respectively arranged at periphery of a display function zone of the touch detection layer, the periphery of the display function zone is provided with N detection zones, each detection zone is provided with one detection wire, one ends of the N detection wires are in ground connection, the other ends of the N detection wires are correspondingly connected with the N connection pins, the N connection pins are correspondingly connected with the N detection units, and the N detection units are used for detecting whether the N detection wires are conducted. According to the screen module, a conduction state of each detection wire is detected, whether the detection zones have micro cracks can be detected respectively, the screen module having a micro crack can be effectively detected, and the location position of the micro crack can be further detected.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a screen module, electronic equipment and a micro-crack detection method for the screen module. Background technique [0002] In recent years, with the rapid development of digital technology and electronic display devices, display technology is undergoing fundamental changes, and more and more screens are widely used in various fields. Most of the screens used in electronic equipment are screen modules composed of high-precision devices made of glass. As one of the main components of electronic equipment, the quality of the screen module plays a decisive role. [0003] At present, due to the increased production cost pressure, many bad screen module manufacturers will ship some defective screen modules that do not affect normal functions to electronic equipment manufacturers. For example, the non-display functional area of ​​the screen has micro crack. However, electronic ...
