Touch screen and panel display module integrated combination module and method for producing the same

Abstract

The invention discloses an integrative composite module of a touch screen and a flat panel display module and a method for manufacturing the same. The composite module comprises the touch screen, the flat panel display module, and a middle adhesive layer for adhering the touch screen and the flat panel display module, wherein the adhesive layer is an optical adhesive layer which fully covers the visual area of the touch screen, and the refractive index of the optical adhesive layer is same as or similar to that of the interface of the touch screen and the flat panel display module. The composite module is provided with the optical adhesive layer between the touch screen and the flat panel display module, and the refractive index of the optical adhesive layer is same as or similar to that of the interface of the touch screen and the flat panel display module, thus the reflectivity of the composite module can be reduced effectively, the light loss of the composite module can also be reduced simultaneously, and the light transmittance of the combined module is improved. The composite module adopts a simple manufacturing method and is easy to operate.

Description

technical field [0001] The invention relates to an integrated combination module of a touch screen and a flat panel display module and a manufacturing method thereof. The touch screen and the flat panel display module are assembled together by using optical glue as an adhesive medium. Background technique [0002] Since Dr. Hurst designed the first transparent touch screen in 1974, the touch screen has achieved rapid development by providing a straightforward and fast man-machine dialogue interface. Products that combine touch screens and display modules can be seen everywhere in the market, especially products that combine touch screens and liquid crystal display modules, such as mobile phones, players, digital cameras, etc. Among them, the application of mobile phones is the most typical and common. Initially, the touch screen and liquid crystal display modules of the mobile phone assembly factory came from different suppliers. Because of the different design concepts and ...

[0006] (2) Second, the dustproof performance is poor

[0007] (3) Third, the contrast is reduced and the display effect is poor

The difference in display effect is divided into two aspects, one is the high reflectivity, such as image 3 As shown, when sunlight irradiates the liquid crystal display module from the outside, the surface of the touch screen 11, the interface between the touch screen 11 and the air gap 13, and the interface between the air gap 13 and the flat panel display module 14 all have about 4% of reflected light due to the difference in the refractive index of the medium. , causing the overall reflectiv
