Problems solved by technology

[0003] In order to realize the touch function, the existing VA screen generally adopts the structure of display screen and touch screen. Generally, it adopts capacitive screen, and uses TP to connect FPC to weld on the display screen. The capacitive screen is easily disturbed during use, and the touch sensitivity is low and reliable. Poor performance, resulting in color unevenness, whitening, and occasional white balance drift

Abstract

The invention relates to an ultra-wide-viewing-angle VA double-sided ITO display module with a touch function and a manufacturing process thereof. The ultra-wide-viewing-angle VA double-sided ITO display module comprises a VA segment code double-sided ITO display screen, which sequentially comprises a bottom protection layer, a bottom ITO layer, a display base material, a top ITO layer, an electromagnetic shielding layer, a polarizing layer and a top protection layer, wherein the top ITO layer is provided with a touch key, and the bottom ITO layer is provided with a display pattern; and two FPC boards, wherein the surfaces of the two FPC boards are attached by grounded shielding films, and the two FPC boards are connected to a common large golden finger, the large golden finger being inserted into a PCB. The top ITO layer is provided with a touch PIN; a display PIN is arranged on the bottom ITO layer; a lower gold finger fixedly connected with the touch PIN is arranged at the end, awayfrom the large golden finger, of one FPC board; and an upper gold finger fixedly connected with the display PIN is arranged at the end, away from the large golden finger, of the other FPC board.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display screens, in particular to an ultra-wide viewing angle VA double-sided ITO display module with touch function and a manufacturing process. Background technique [0002] VA screen, the liquid crystal molecules are twisted towards a certain angle but not vertical. At present, there are mainly MVA panels dominated by Fujitsu and PVA panels dominated by Samsung. The VA screen is a wide viewing angle screen, the viewing angle can reach 178° close to the horizontal, and the gray scale response time can reach below 8ms. [0003] In order to realize the touch function, the existing VA screen generally adopts the structure of display screen and touch screen. Generally, it adopts capacitive screen, and uses TP to connect FPC to weld on the display screen. The capacitive screen is easily disturbed during use, and the touch sensitivity is low and reliable. Poor performance, resulting in color ...
