Problems solved by technology

[0003] like figure 2 As shown, the performance of Color Saturation (CS) cannot achieve the same effect of full lamination. Although the effect of full lamination is better than that of frame paste, it is technically difficult and the equipment is expensive. If the lamination parameters are abnormal, it will It affects the overall flatness of the product, and it is not easy to rework, and the cost of rework will be relatively high

Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0031] The disadvantages of traditional frame stickers are that the color saturation and contrast cannot achieve full bonding effect, and the light will be reflected repeatedly inside, resulting in loss of light energy and image quality, such as image 3 , when the user uses touch to watch, it is easy to produce a sense of distance. In terms of reflectivity, when the light passes through the interface of two different materials, the reflectance on the interface is the largest at this time. If OCA is used as the medium, the two different materials can achieve optical matching. For light, it is quite The same material, so the maximum reflectivity will be on t...

Abstract

The invention discloses a touch control display. The touch control display comprises a display module, a touch control module and an optical unit, wherein the touch control module is connected with the display module in a frame pasting mode, a closed gap space is formed between the touch control module and the display module, the gap space is in a vacuum state, and the thickness of the gap space ranges from 0 mm to 3 mm; and the optical unit is arranged on at least one of the display module and the touch module and is adjacent to the gap space, the optical unit comprises an anti-reflection layer or an anti-glare layer or a combination of the anti-reflection layer and the anti-glare layer, the reflectivity of the anti-reflection layer is 0.3-3%, and the haze of the anti-glare layer is 4-60%. According to the touch control display, through adopting the optical technology and small fixing parts, the defects of optical visual effect can be effectively solved, the whole framework can be protected from deformation, and the existing frame pasting technology can achieve the full pasting effect.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a touch display. Background technique [0002] Most of the capacitive touch displays on the market have their touch components built on the protective cover, and the touch coordinates are obtained through the capacitance value between the user's finger and the touch component, and the bonding of the touch component and the display The method can be divided into air bonding and direct bonding, and because the intermediate medium of frame bonding is air, and in order to avoid Newton rings, the height of the air layer must be sufficient, generally 3mm~10mm. like figure 1 As shown, the user will have a sense of distance between the finger position and the display position when viewing. In terms of reflectivity (R%), contrast ratio (Contrast Ratio, CR), [0003] like figure 2 As shown, the performance of Color Saturation (CS) cannot achieve the same effect of full ...
