Abstract
The present disclosure provides a touch display device including a display panel, a touch panel, and a cover plate. The side of the touch panel adjacent to the display panel is provided with a recess and a surrounding portion surrounding the recess. By vacuuming the gap formed between the display panel and the touch panel, a portion of the touch panel is recessed into the gap, which reduces the space occupied by the gap, eliminates the sense of space, enhances waterproof and dustproof effects and elevates stability.
Claims20
A touch display device, comprising:
- a display panel;
- a touch panel disposed on the display panel, wherein a side of the touch panel adjacent to the display panel is provided with a recess and a bonding portion surrounding the recess, the recess is located at a middle of the touch panel, the bonding portion is located at a peripheral of the touch panel, and the recess is recessed toward a side of the display panel;
- and
- a cover plate disposed on the touch panel,
- wherein a first colloid is disposed on an area corresponding to the bonding portion between the display panel and the touch panel, to bond the display panel with the touch panel;
- a second colloid is disposed between the touch panel and cover plate, to bond the touch panel with the cover plate;
- and a cavity is enclosed between the display panel, the touch panel, and the first colloid.
