Abstract

The invention discloses a curved screen defect detection method and device, and the method comprises the following steps: providing a machine table, and placing a to-be-detected curved screen on the machine table; the machine table is moved to the position below a lens of a camera; and the camera photographs the arc edge of the curved screen to detect whether defects exist or not. The method has the technical effect that the crack defect detection efficiency is improved.

Description

technical field [0001] The present application relates to the display field, and in particular to a method and a detection device for detecting defects of curved screens. Background technique [0002] Due to the increasing demand of consumers, many curved display screens (such as curved rigid screens and curved flexible screens) have emerged at the historic moment, and the glass screen body will produce various defects during the bending process. Through multi-degree-of-freedom and multi-degree-of-freedom adjustment of the camera mechanism, crack defects generated during glass bending can be detected. [0003] The existing detection method still adopts the traditional human eye detection method, which has the following defects: long-time work of personnel will cause greater damage to the eyes, eye fatigue leads to a low detection rate of defects, and for subtle defects invisible to the naked eye, human eyes cannot detect them. It cannot be detected, the labor cost is huge, ...
