Abstract

The invention discloses a touch display device and a manufacturing method thereof. In a panel laminating process, ae display panel and a touch panel are attached through the liquid optical cement by adopting a full-attaching technology, a cover plate and the touch panel are attached through the solid optical cement by adopting a frame attaching technology to form the vacuum cavity. The cover plate, the touch panel and the display panel in the formed touch display device are tightly attached, and optical cement materials are effectively saved.

Description

Technical field [0001] The present invention relates to the field of display technology, and in particular to a touch display device and a manufacturing method thereof. Background technique [0002] Touch Panel (TP), 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 conductors such as a human body or a capacitive pen to input instructions. It can replace a mouse, keyboard, etc. Input devices such as external input devices and mechanical input keys can effectively simplify the structure of electronic products such as computers, mobile phones, electronic meters, and game equipment, and have very broad application prospects. In terms of technical principles, touch panels are mainly capacitive, resistive, ultrasonic, and infrared. [0003] Infrared touch technology currently occupies a large part of the touch market with its accurate touch accuracy and relatively low cost advantages. However, infrared tou...
