Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a method for manufacturing a plane-switching IPS screen, by etching two layers of ITO separately, which can effectively increase the gap between each ITO layer without increasing the complexity of the process and without affecting the performance of the product. spacing, to avoid the problem of circuit short circuit caused by too small spacing between ITO layers

Abstract

A method of fabricating an In-Plane Switching (IPS) screen electrode is proposed so as to address the problem in the prior art that concurrent fabrication of both a pixel ITO layer and a common ITO layer may result in a lowered spacing between the respective ITO layers, which may easily cause a short circuit. In the method, firstly a first ITO layer is etched, and the etched first ITO layer is annealed, then a second ITO layer is etched, and finally the etched first ITO layer and the etched second ITO layer are annealed concurrently. With this method, the etched first ITO layer is annealed after the first ITO layer is etched, subsequent etching of the second ITO layer will have no influence upon the annealed first ITO layer, thus making it possible to ensure the line widths of the two ITO layers and a spacing between the respective ITO layers to thereby effectively avoid the problem of a short circuit due to a too small spacing between the respective ITO layers.

Description

technical field [0001] The invention relates to the field of displays, in particular to a method for manufacturing plane switching IPS screen electrodes. Background technique [0002] In-plane switching IPS (In-panel switching) technology is a liquid crystal panel technology launched by Hitachi in 2001. The biggest feature of the IPS screen manufactured by this technology is that both levels are on the same surface, and the arrangement of liquid crystal molecules is adjusted. For optimization, horizontal arrangement is adopted. When encountering external pressure, the molecular structure is slightly depressed downwards, but the overall molecules are still horizontal, so that there will be no distortion of the picture, and it will not affect the color of the picture. Due to the above advantages, IPS screens play an increasingly important role in the display field. [0003] The IPS screen electrode includes a pixel ITO layer and a common ITO layer. When manufacturing IPS sc...
