Touch control module window hidden type clinging structure

Abstract

The invention discloses a touch control module window hidden type clinging structure which comprises a touch screen glass cover plate, a transparent optical adhesive, a touch screen function sheet, a polaroid, an ultralow reflection membrane A, an ultralow reflection membrane B, an LCD (Liquid Crystal Display) and a backlight plate which are overlapped in sequence from top to bottom, wherein a touch screen comprises the touch screen glass cover plate, the transparent optical adhesive and the touch screen function sheet; the touch screen glass cover plate is connected with the touch screen function sheet through the transparent optical adhesive; the touch screen, the LCD and the backlight plate are connected through a foam adhesive; an included angle of 45 degrees is formed between the polaroid and the polaroid on the LCD. The touch control module window hidden type clinging structure is reasonable in structural design, compact in structure, relatively low in cost, high in clinging yield, simple in clinging process, small in equipment investment, simple in rework and low in rejection rate and can be very well applied to vehicle-mounted devices, medicinal instruments and industrial control products, a complete clinging effect is achieved, the clinging cost can be very well controlled, an integral dark display effect is achieved, and different requirements of customers can be met.

Description

technical field [0001] The invention relates to the technical field of touch display modules, in particular to a hidden bonding structure of a touch module window. Background technique [0002] At present, there are two types of bonding technologies commonly used for touch modules and display modules: full bonding and frame bonding. Full bonding uses optical glue or water glue to seamlessly bond the touch screen and display panel on the entire surface of the window area. Frame bonding is The touch screen and the display panel are bonded with frame glue, and the frame glue is hidden in the ink area of ​​the touch screen, while the touch screen and the display panel are separated by a gap of the thickness of the frame glue. However, in the existing bonding technology, when the display panel is not lit, the visual contrast between the touch window and the ink area of ​​the panel is relatively large, the boundary between the window and the ink area is clear, and even the graphic...

However, in the existing bonding technology, when the display panel is not lit, the visual contrast between the touch window and the ink area of ​​the panel is relatively large, the boundary between the window and the ink area is clear, and even the graphics or metal bridge points of the rear sensor can be seen. Affect the overall visual effect of the touch panel

[0003] At present, the method of achieving the integrated black effect of the touch screen cover is generally achieved by using glass or plastic materials with neutral gray light reduction effects, or coating a semi-reflective and semi-permeable film on the cover by vacuum sputtering. The one-piece black effect of the cover plate made of the cover material with medium gray light reduction effect is better, but there are problems of high material price and shortage of supply resources; the one-piece black of the vacuum sputtering coating method cannot achieve a real black background, and will appear A bright white specular reflection effect, in most cases, cannot meet people's requirements for a one-piece black effect, and there is also a problem of high price
