Problems solved by technology

[0003] However, based on the structural design of the current touch display device, there is a gap between the end of the flexible touch circuit board 6 ′ bound to the touch substrate 2 ′ and the cover 5 ′, which causes the flexible touch circuit board 6 'When bending, the end will be upturned (the flexible touch circuit board 6' after the uplift is as figure 1 shown in the dotted line box in ), resulting in the disconnection of the pins originally bound together in the flexible touch circuit board 6' and the touch substrate 2', thereby adversely affecting the touch performance

Abstract

The embodiment of the invention provides a touch display device, relates to the technical field of display, and is beneficial to narrow frame and light and thin design of the touch display device while improving the binding reliability of a flexible touch circuit board and a touch substrate. The touch display device comprises a display module, a touch substrate, a polaroid, an adhesive film and acover plate which are sequentially arranged in the light emitting direction of the touch display device, the touch substrate comprises a touch area and a binding area, and the polaroid covers the touch area; the touch display device further comprises a flexible touch control circuit board, the thickness of the flexible touch control circuit board is smaller than that of the polaroid, the flexibletouch control circuit board comprises a binding part and a bending part, and the flexible touch control circuit board is bound to the binding area through the binding part. A gap between the binding part and the first structure is filled with a filling structure, the filling structure and the adhesive film are independent of each other, and the first structure is the structure, closest to the binding part, in the structure of the side, facing the light emitting direction, of the binding part.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a touch display device. 【Background technique】 [0002] With the rapid development of display technologies, touch display devices with touch functions have gradually spread in people's lives. like figure 1 as shown, figure 1 It is a structural schematic diagram of a touch display device in the prior art. The touch display device includes a display module 1', a touch substrate 2', a polarizer 3', a bonding The adhesive film 4' and the cover plate 5'. In addition, the touch display device also includes a flexible touch circuit board 6' that transmits touch signals to the touch substrate 2', and the flexible touch circuit board 6' and the touch substrate 2' bound together and bent to the backlight side of the display module 1'. [0003] However, based on the structural design of the current touch display device, there is a gap between the end of the flexible touch cir...
