Full-transparent frameless touch screen

Abstract

The invention belongs to the technical field of touch display, and provides a full-transparent frameless touch screen, which comprises a transparent glass cover plate, a transparent OCA (Optical Cement) layer and a transparent flexible touch sensing plate which are sequentially laminated, wherein a bulge part with the same material as the touch sensing plate is fixedly arranged on one end of the touch sensing plate, extends outwards and is curved in an arc shape; a flexible printed circuit board is tied on the outer end of the bulge part. According to the full-transparent frameless touch screen, the bulge part can extend to the inner part of a case matched with a touch screen or the back part of a display screen, so that the flexible printed circuit board can be arranged in the inner part of the case or the back part of the display screen, the aim of shielding the flexible printed circuit board by the inner part of the base or the back part of the display screen is achieved, the flexible printed circuit board has no need to be shielded by a frame arranged specially, the touch screen is frameless and full-transparent, and the display area and the touch area of the touch screen are enlarged.

Description

technical field [0001] The invention belongs to the technical field of touch display, in particular to a fully transparent borderless touch screen. Background technique [0002] At present, after the touch-sensitive sheet of the existing touch screen is bonded to the flexible circuit board (FPC), in order to avoid the appearance of the flexible circuit board and affect the appearance, the frame is used to cover the flexible circuit board. Due to the existence of the frame, it is bound to be reduced. If the display area and touch area are limited, it cannot meet the user's requirement of borderless. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a fully transparent borderless touch screen that can expand the display area and touch area. [0004] The present invention is achieved in this way. A fully transparent borderless touch screen includes a transparent glass cover pl...
