Abstract

Embodiments of the present invention provide an optical detection device and a control method thereof, which relate to the technical field of liquid crystal display and can solve the problems of high cost and large space occupation of the optical detection device in the prior art. The optical detection device includes a base platform; a plurality of clamping units are arranged on the base platform, and each clamping unit can clamp a display device to be detected, and the clamping unit of each clamping unit The holding angle can be adjusted; the image acquisition unit, the image acquisition unit is arranged above the clamping unit, and is used to collect the grayscale image of the display device to be detected; the control unit, the control unit is connected with the image acquisition unit and multiple clamping units, The control unit is used for controlling the clamping angle of each clamping unit according to the grayscale image collected by the image capturing unit. The invention is used for testing display devices.

Description

Technical field [0001] The present invention relates to the field of liquid crystal display, and more particularly to an optical detecting device and a control method thereof. Background technique [0002] During the production of the display device, the quality detection of the display screen is usually performed before the product is factory factory, and it is determined whether it meets the requirements of customer standards. The display device is used to optically detect the display device using AOI (Automated Optical Inspection, Automatic Optical Optical Detection). reference figure 1 with figure 2 As shown, in view of factors such as cost and space, the industry generally uses high-resolution CCD (Charge-Coupled Device, charge coupled device) lens 02 simultaneously optically detects the plurality of display device 01, although the existing CCD lens 02 can Autofocus, but during the actual detection, due to the center point of the CCD lens 02, the center point of the displa...
