Abstract

The invention provides an infrared touch display device and a preparation method thereof. The method comprises the steps that a cover plate coated with frame glue and a display panel to be attached are fed into a vacuum cavity, and vacuumizing treatment is conducted in a sealed environment; when the cover plate is attached to the display panel, the portion, corresponding to the middle area definedby the frame glue, of the cover plate is sunken towards one side of the display panel and is tightly attached to the display panel, and the peripheral edge of the display panel and the peripheral edge of the cover plate are sealed through the frame glue; and then a plurality of groups of infrared transmitting tubes and infrared receiving tubes are arranged at the periphery of the cover plate in aone-to-one correspondence manner. The cover plate and the display panel are attached in a vacuumizing mode, the dustproof and waterproof effects are achieved, meanwhile, the display device has no feeling of being separated from the air, and therefore the experience comfort degree is improved.

Description

technical field

[0001] The present application relates to the field of display technology, in particular to an infrared touch display device and a manufacturing method thereof. Background technique

[0002] In the field of display, infrared touch is currently occupying a large part of the touch market due to its mature technology, accurate touch accuracy, and relatively cost advantages. Infrared touch is to analyze the touch position by blocking the infrared rays emitted by the infrared frame for positioning. The bonding between the display panel and the glass cover generally utilizes direct bonding technology (Direct Bonding) or frame bonding technology (Air Bonding) as the main bonding technology. Among them, the cost of the touch display device bonded by the frame mount technology is lower than that of the touch display device bonded by the surface mount technology. However, due to the use of frame-mounting technology, a cavity will be formed between the middle area of ...
