Abstract

The invention relates to a capacitive module screen appearance detection system and method. The system comprises a front linear array scanning detection device, a front multi-light-source combined detection device, a front edge detection device, a back overall detection device, a first carrying platform, a second carrying platform, a first mechanical arm and a second mechanical arm. By arranging the front linear array scanning detection device, the front multi-light-source combined detection device, the front edge detection device and the back overall detection device, various defects of a capacitive module screen to be detected can be comprehensively detected, and the comprehensiveness and the accuracy of detection are ensured. In addition, the first carrying platform, the second carryingplatform and the mechanical arm are arranged to coordinate operation among the detection devices, and the detection efficiency of the whole detection process can be improved.

Description

technical field [0001] The invention relates to the field of optical detection, in particular to a capacitive module screen appearance detection system and method. Background technique [0002] With the rapid upgrading of the smart terminal industry, a huge market demand for liquid crystal display panels has been created. At present, as the core part of smart terminals, smart phones mainly use TFT-LCD capacitive touch screens as display panels, and the market for OLED display panels is still immature. The TFT-LCD capacitive touch display is mainly composed of a thin film conductive layer, a lower glass substrate for TFT, an upper glass substrate for color filtering, and a liquid crystal cell. TFT is a thin-film electrode tube, which can control the rotation direction of liquid crystal molecules through the change of signal and voltage, change the light direction of the bottom backlight, and finally realize the three-primary-color light-emitting control through the color fil...
