The invention relates to a method for improving the display gray scale difference of a display panel. The display panel comprises a pixel electrode and a common electrode which are strips. The method for improving the display gray scale difference of the display panel comprises the steps that S1, several groups of simulation parameters are set, wherein the simulation parameters include the width of the pixel electrode and the width of the common electrode; S2, on the condition of each group of the simulation parameters, the display gray scale difference of the display panel is tested; S3, whether the display gray scale difference of the display panel conforms to the requirement or not on the conditions of all the groups of the simulation parameters is determined; if it is determined that the display gray scale difference of the display panel conforms to the requirement in the S3, the display panel is prepared according to the one or more groups of simulation parameters conforming to the requirement; and if the display grey scale differences of the display panel under the condition of multiple groups of simulation parameters fail to meet the requirement, resetting the simulation parameters, and S1, S2 and S3 are repeated. By means of the method, the display gray scale difference of the display panel can be improved, and the display uniformity can be increased.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a method for improving the display gray scale difference of a display panel. Background technique [0002] In the display device, for example, TFT-LCD and AMOLED display panel, it comprises a plurality of electrodes and thin film transistor etc., described electrode and gate in thin film transistor, gate insulating layer, active layer, source electrode and drain electrode are respectively located in different layers, so that the display device has a multi-layer structure. When forming each layer structure of a display device, a specific material layer is generally formed by deposition, sputtering, etc., and then exposed and developed using a mask, and the specific material layer is patterned by etching to form a layer structure. [0003] In the actual preparation process, due to the different sizes, pattern densities and other factors of each layer structure, there are...
