Problems solved by technology

However, in the face of making large-sized touch display devices (such as touch panels above 55 inches) (Cover Lens), in consideration of assembly yield and convenience, the cover plate needs to have a certain thickness and weight. To maintain a certain degree of toughness, it is difficult to stably fix and assemble on the display panel only by relying on a layer of OCA

Abstract

A touch display device comprises a cover plate, a touch module, a frame and a display module. The touch control module is arranged on the cover plate and defines a sensing area and a peripheral area which are connected with each other. The frame is located on the side, away from the cover plate, of the touch module and comprises a plurality of fixing pieces and a containing groove. The fixing pieces penetrate through the peripheral area and are fixedly connected with the cover plate. At least one part of the touch module in the peripheral area is attached to one side, far away from the cover plate, of the frame. The display module is arranged in the containing groove and located above the induction area. Therefore, the structure of the touch module and the display module which are large in size can achieve enough bearing strength when the touch module and the display module are assembled.

Description

technical field [0001] The invention relates to a touch display device. Background technique [0002] At present, the design of narrow border (Narrow Border) touch display devices is mainly to reduce the width of the touch panel frame (BM area) as much as possible. The part of the panel extending out of the sensing area is bent to the back of the display panel along the non-attaching area of ​​the outer edge of the display panel, and fixed with an adhesive. [0003] In order to realize the narrow frame of the touch display device, the cover plate and the display panel are usually fixed and assembled together only by Optically Clear Adhesive (OCA). However, in the face of making large-sized touch display devices (such as touch panels above 55 inches) (Cover Lens), in consideration of assembly yield and convenience, the cover plate needs to have a certain thickness and weight. To maintain a certain strength and toughness, it is difficult to stably fix and assemble on the dis...
