Abstract

The invention discloses a sealing method for a bound region in an ON-CELL product. The method comprises the steps of preparing TFT upper glass and TFT lower glass, wherein the TFT lower glass is wider than the TFT upper glass; attaching a lower polarizer to the lower surface of the TFT lower glass; binding a driver integrated circuit (IC) to the upper surface of the TFT lower glass, wherein the driver IC is not in contact with the TFT upper glass; binding a lower glass binding pin to the upper surface of the TFT lower glass, and binding a lower glass FPC to the lower glass binding pin, wherein the driver IC is not in contact with the lower glass FPC; binding an upper glass binding pin to the upper surface of the TFT upper glass, and binding an upper glass FPC to the upper glass binding pin, wherein the driver IC is not in contact with the upper glass FPC; and attaching an upper polarizer to the upper surface of the TFT upper glass, wherein the width of the upper polarizer is greater than the length of the lower polarizer, and the end part of the upper polarizer covers the end part of the upper glass FPC. The method has the beneficial effects that the sealing effect of the bound region in the ON-CELL product is enhanced; and the problem of poor sealing property caused by the fact that line glue cannot be applied to the ON-CELL product is solved.

Description

technical field [0001] The invention relates to the technical field of touch display, in particular to an ON-CELL product and a sealing method for its binding area. Background technique [0002] At present, the most important development direction of the whole machine is light and thin, the lighter and thinner the more convenient to carry, the visual requirements are getting higher and higher, such as narrow bezel technology; the ON-CELL technology dominated by the TFT display panel industry has become the mainstream technology of competition. [0003] In the whole capacitive touch screen manufacturing process, the quality of dispensing in the bonding area will directly affect the service life of the product. The water vapor and impurities that appear during production and use will gradually corrode the bonding area, causing abnormalities in the connection of the gold fingers in the bonding area, and even oxidation, corrosion, and fracture. This causes a great reliability r...
