Inspection device and control method of liquid crystal display panel

Abstract

The invention relates to a check device of a liquid crystal display panel and a control method thereof. The check device comprises: a data probe unit with respect to one surface of the liquid crystal display panel and grid probe units with respect to two surfaces of the liquid crystal display panel; data side movement parts and grid side movement parts arranged the each orientation of the data probe unit and the grid probe units have in the mutual cross mode; probe automatic replacing part moved by each movement part and arranged to freely move according to the size of the liquid crystal display panel; and a camera mechanism grasping the movement positions of the data probe units and the grid probe units and the movement position of the probe block contacted with the liquid crystal display panel. The invention has the advantages with no need for replacing or changing the probe unit.

Description

technical field [0001] The present invention relates to a liquid crystal display panel inspection device and control method thereof (Test Apparatus of Liquid Crystal Display Panel and Control Method Thereof), in particular to a liquid crystal display panel inspection device and its control method, the liquid crystal display panel inspection device, Not only the data probe unit and the gate probe unit can be freely moved in the direction to be moved, but also a plurality of probes provided in these probe units can be selectively used according to the size of the liquid crystal display panel , so that the probes provided in each probe unit can be finely adjusted to the desired position of the liquid crystal display panel. Background technique [0002] Generally speaking, the inspection device of the liquid crystal display panel uses a probe unit to fix the display panel to the position where the operator is so that the inspection device is used for inspection according to the ...
