Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.
[0029] In the liquid crystal display panel of the prior art, since it is impossible to measure and monitor the anchoring energy between the alignment film and the liquid crystal during the production process, a large number of abnormal products occur, which affects product quality and production efficiency. This embodiment can solve this defect .
[0030] Such as figure 1 As shown, the schematic diagram of the structure of the liquid crystal display panel provided by the...

The present invention provides a liquid crystal display panel including a display area and a non-display area located outside the display area. The non-display area is internally provided with a testpanel prepared according to a part of a functional layer of the liquid crystal display panel in the same process, and the test panel is used for display the light transmittance of the liquid crystal display panel under different voltage differences. The method has the advantages that the panel light transmittance under different voltages is obtained by setting the test panel prepared according toa part of the functional layer of the liquid crystal display panel in the same process and by externally connecting a fixed voltage and changing a test voltage, the anchoring energy of an alignment film and liquid crystal is obtained after calculation, a product is monitored in real time in the production process, and the appearance of a large number of abnormalities is prevented.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and a method for testing liquid crystal anchoring performance thereof. Background technique [0002] TFT LCD (Thin Film Transistor Liquid Crystal Display, Ultra-thin Film Transistor Liquid Crystal Display) mainly provides an electric field to the liquid crystal through the transparent conductive film under the alignment film, and the electric field deflects the liquid crystal to realize the bright and dark display of the display device. The alignment film is The deflection of the liquid crystal provides a certain pre-tilt angle, the purpose is to make the liquid crystal deflect more easily in the electric field, the pre-tilt angle of the liquid crystal is mainly affected by the anchor energy between the alignment film molecules and the liquid crystal molecules, but how to adjust the alignment during the production process of the liquid crystal displ...
