Problems solved by technology

[0002] The traditional anti-interference measure is to add capacitors, resistors or other components to the drive circuit PCB around the LCD. This method requires a relatively large space and is suitable for display modules with large sizes and loose structures.
However, it is difficult to realize the small and exquisite LCD products on the COG+FPC structure.

Abstract

The invention discloses an LCD module and a method for improving the interference resistance of an LCD. According to the LCD module and the method for improving the interference resistance of the LCD through an ITO graph planar inductor, the LCD module which is manufactured by designing a spiral type ITO planer inductor between an integrated circuit controller IC on ITO glass and a flexible printed circuit board FPC structurally comprises a piece of upper ITO glass, frame rubber, a piece of lower ITO glass, a liner, a lower ITO layer, super twist nematic liquid crystal, a lower liquid crystal alignment film, a lower transmission film polaroid, an upper elliptic single-compensation film polaroid, an upper liquid crystal alignment film, an upper ITO layer, the ITO graph planar inductor, the integrated circuit controller IC, a piece of anisotropic conductive adhesive tape ACF and the flexible printed circuit board FPC. The LCD module and the method have the advantages that the LCD module and the method are suitable for a display screen of a COG+FPC structure, similar circuits are prevented from being added to the periphery of the LCD, reliability is high, the process method is simple, and production cost and material cost are low.

Description

technical field [0001] The invention relates to an LCD liquid crystal display module and a method for improving the anti-interference ability of the LCD by using an ITO graphic planar inductance, and belongs to the technical field of liquid crystal display screens. Background technique [0002] The traditional anti-interference measure is to add capacitors, resistors or other components to the drive circuit PCB around the LCD. This method requires a relatively large space and is suitable for display modules with large sizes and loose structures. However, it is difficult to realize the small and exquisite LCD products on the COG+FPC structure. Therefore, it is most suitable for LCD manufacturers to use the inductance of ITO on the product glass itself to suppress various noise interference without increasing cost and design difficulty. This method of using ITO graphic planar inductance to improve the anti-interference ability of LCD is to use the square impedance of ITO glas...
