Example Embodiment

[0045] The preparation method of the touch display screen provided by the present invention is to squeeze the touch screen and the TFT module in a non-vacuum state. By squeezing the touch screen and the TFT module, the touch screen and the TFT module can be pressed together. The air bubbles can be discharged. The method can be realized in a non-vacuum state, and the equipment does not need to be evacuated, thereby saving the time of evacuating and improving the production efficiency.

[0046] In addition, the present invention innovatively uses an extrusion method to bond the touch screen and the TFT module in a non-vacuum state, which is completely different from the traditional vacuum process for bonding, and creates a new bonding process technology to improve Production efficiency provides new ideas.

[0047] The non-vacuum state referred to in the present invention refers to a normal pressure state. Normal pressure is an atmospheric pressure, which is the pressure of the gas p...

Abstract

The invention provides a preparation method of a touch display screen and a bonding device and relates to the technical field of the preparation of an electronic device display screen. The method comprises a step of bonding a touch screen and a TFT module in a non-vacuum state by using a pressing mode. According to the preparation method and the bonding device, the technical problem of low efficiency in bonding production by using vacuum in the prior art is alleviated, and a technical effect of improving the production efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of preparation of display screens of electronic equipment, in particular to a preparation method and bonding equipment of touch display screens. Background technique [0002] TFT (Thin Film Transistor) is the abbreviation of thin film transistor. Each liquid crystal pixel on the TFT display is driven by a thin film transistor integrated behind the pixel, so the TFT display is also a type of active matrix liquid crystal display device, which is the best LCD (Liquid Crystal Display, liquid crystal display) ) One of the color displays, the TFT display has the advantages of high responsivity, high brightness, and high contrast. At the same time, TFT screens are also widely used in mid-to-high-end color screen mobile phones, and their display effects are very good. [0003] With the rapid development of electronic equipment and the touch control of electronic display products, more and more touch screen and LCD...
