Embodiment Construction
[0025] Such as figure 1 Shown is a schematic structural diagram of Embodiment 1 of the liquid crystal panel testing device of the present invention. This embodiment is applied to the detection of the level shift of the stressed layer of the substrate in the production process of the liquid crystal panel. The device includes: two longitudinal guide rails 1, as shown in FIG. The space between is used to place the liquid crystal panel 2 to be detected, that is to say, the conveyer belt used to accommodate the liquid crystal panel 2 passes in the space between it; the transverse guide rail 3, such as Figure 2B As shown, a chute is provided on it, and the transverse guide rail 3 is built on two longitudinal guide rails 1, which can slide longitudinally along the longitudinal guide rail 1, and the transverse guide rail 3 is located above the liquid crystal panel 2 to be detected; the sliding device 4 is arranged on On the transverse guide rail 3, slide horizontally above the liqu...

The invention relates to a liquid crystal panel testing device which comprises a longitudinal guideway, a transverse guideway which is glidingly overlapped on the longitudinal guideway, a sliding device which is glidingly connected with the transverse guideway, a reciprocating device which is connected with the sliding unit and driven by the sliding device to move above a liquid crystal panel to be tested and a beating device which is connected with the reciprocating device and driven by the reciprocating device to set frequency and an impulsive force to beat the liquid crystal panel. The liquid crystal panel of the invention can accurately control the beating action in testing, control the position, the strength and the frequency of the beating, thus the conditions for forming relative displacements of the upper base plate and the lower base plate of the liquid crystal panel are consistent, so that the errors which are caused by man-made factors are reduced, and then the accuracy of the grade judging is improved.
Description
technical field [0001] The invention relates to a liquid crystal panel detection device, in particular to a device for detecting light leakage caused by upper and lower substrates in the online quality detection of liquid crystal panels. Background technique [0002] The display principle of the liquid crystal display is mainly to use an electric field to control the orientation of the liquid crystal molecules, and the anisotropy of the refractive index of the liquid crystal changes the transmittance to display. Its main structure is composed of array substrate, color filter substrate, polarizer, backlight and liquid crystal. The most important thing in the manufacturing process of liquid crystal display is the box forming process of array substrate and color filter substrate. In the process of forming a cell, the alignment film material is first coated on the substrate and through the corresponding orientation process, so that the liquid crystal molecules can be arranged i...
