Abstract

The invention provides a test device and a test method for a liquid crystal module. The test device for the liquid crystal module comprises a controller, a driving module, a test bench and a camera, wherein the controller is used for processing an image acquired by the camera; the driving module is used for driving a liquid crystal display panel to be tested according to a received control signal; the test bench is positioned above a test frame and used for fixing the liquid crystal display panel to be tested; and the camera is arranged on the test frame and used for acquiring the image of the liquid crystal display panel to be tested when the liquid crystal display panel to be tested is lightened. Compared with the test method in which a manual operation fixture is adopted and whether the liquid crystal display panel has color dots or not is judged in a visual observation mode in the prior art, the test method for the liquid crystal module has the advantages that: the camera acquires the frame of the liquid crystal display panel in real time and transmits image data to the controller, and the controller processes the image data and can automatically determine the condition that the color dots occur on the liquid crystal display panel, so that the labor intensity of people is reduced, and test efficiency is improved.

Description

technical field [0001] The invention belongs to the field of liquid crystal module testing, and in particular relates to a liquid crystal module testing device and a testing method thereof. Background technique [0002] During the process of assembling the liquid crystal display panel into a liquid crystal display module (liquid crystal module, LCM), it is necessary to conduct a series of performance tests on the liquid crystal display panel. For the manufactured liquid crystal display panel that has not yet been pressed with an LCD driver chip, it is necessary to test its display function. In the process of testing, it is necessary to strictly test the occurrence of color dots on the liquid crystal display panel. When the number of color dots exceeds the allowable range, the test cannot be passed. At present, for the display test of the liquid crystal display panel, the liquid crystal display panel is generally placed on the corresponding fixture by manual method, and the ...
