Abstract

The invention discloses a touch display device and a manufacturing method thereof. In the panel laminating process, a cover plate and a touch panel are attached to form a cover plate assembly throughliquid optical cement by means of the full-attaching technology. The cover plate assembly is attached to the display panel through the solid-state optical cement by means of the frame attaching technology, the vacuum cavity is formed, the cover plate, the touch panel and the display panel in the formed touch display device are tightly attached, optical cement materials are effectively saved, the production cost is reduced, and the product yield is increased.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display device and a manufacturing method thereof. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with touch function are widely used in people's daily life and work, which brings great convenience to people's daily life and work. Touch technology is an important link in the process of human-computer interaction, and display devices such as smart phones and tablet computers all need the support of touch technology. [0003] Touch Panel (TP for short), also known as touch screen or touch screen, is a device that is formed on the display surface of an image display device and uses a conductor such as a human body or a capacitive pen to input commands. It can replace the mouse, keyboard, etc. Input devices such as external input devices and mechanical input keys can effectively simplify the ...
