Problems solved by technology

[0003] However, in the prior art, since the test indenter 100 is integrally formed, when the T / P sensor 120 is pressed, the continuity of its pressing strength cannot be guaranteed, that is, it will appear that some pressing areas are relatively tight, and the The sensing signal is relatively strong, but in some pressing areas it is relatively loose and the sensing signal is relatively weak
After the above situation occurs, it is necessary to adjust the descending depth of the test indenter 100. This adjustment needs to disassemble the test indenter 100 as a whole, and then deepen the thickness of the area where it is not tightly pressed. However, this adjustment method is not only too cumbersome. , in the adjustment process, it is impossible to immediately reflect whether the degree of adjustment meets the requirements, which is very unfavorable for the stability of the test equipment

Abstract

The invention relates to a testing device of a touch control liquid crystal panel, comprising a plurality of testing sub press heads arranged at an X direction or a Y direction, wherein the testing sub press heads are provided with regulating devices so as to regulate each sub press head independently without needing to detach the testing press heads completely, thereby, the instability of regulation is avoided, the time for regulation and testing is saved, and the work efficiency is improved.

Description

technical field [0001] The present invention relates to a test device for a touch liquid crystal panel, in particular, the present invention relates to a test device for a touch liquid crystal panel which has a plurality of sub-indenters and can individually adjust the pressing depth. Background technique [0002] In recent years, touch-type liquid crystal panels have been increasingly used in various display technologies, such as mobile phones, monitors, televisions, personal data processing terminals, and the like. The more common touch LCD panel is to install a layer of conductive film and sensors on the outside of the LCD panel, and trigger the sensing signal by pressing with a finger or a pen tip to achieve the purpose of controlling the display to display a specific pattern. For this kind of touch liquid crystal display panel, in the final link of production, the factory needs to conduct a power-on and press test to detect the signal sensitivity of the conductive film ...
