Problems solved by technology

With this detection method, after the front side of the display panel has been detected, the rear side of the display panel needs to be turned over manually before the back side of the display panel can be detected. The detection efficiency is low, and the display panel is easily damaged by turning over the display panel manually

Abstract

The invention relates to the technical field of display panel detection, and discloses a detection device and a detection method of a display panel. The detection device includes a light box mechanism, an upper transmission mechanism and a light box turning mechanism. The light box mechanism is used to carry the workpiece to be detected and provide illumination for the detection of the workpiece to be detected. The upper transmission mechanism is configured to grab the workpiece to be detected on the light box mechanism. The light box turning mechanism is configured to drive the light box mechanism to turn over to adjust the included angle between the light box mechanism and the horizontal plane. Through the cooperation of the upper transmission mechanism and the light box turning mechanism, the inspection of both sides of the display panel can be completed in sequence with only one feeding, and the inspection efficiency is high.

Description

technical field [0001] The present invention relates to the technical field of display panel detection, and in particular, to a detection device and a detection method of a display panel. Background technique [0002] The display panel is the liquid crystal screen, which determines the brightness, contrast, color and viewing angle of the liquid crystal display to a large extent. Its quality is not only related to the quality, price and market trend of the liquid crystal display itself, but also related to the whole product. Function parameters, display effect and service life, etc. [0003] Usually, before the display panel leaves the factory, it is necessary to perform corresponding detection on the front and back of the display panel, mainly to detect whether the brightness of the front of the display panel is consistent, and whether there is dirt on the back of the display panel. The detection method in the prior art is usually as follows: firstly, the display panel is p...
