It is to be understood that the disclosed embodiments are merely exemplary of the invention, and are not intended to limit the invention to the precise embodiments disclosed. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model discloses an integrated touch-control display module assembly includes backlight module, display panel, first graphite flake 3 and heat conduction double faced adhesive tape 4 (shown in fig. 1). The backlight module can be a direct type backlight module or a side type backlight module. Taking the lateral type backlight module as an example, the backlight module includes a frame 1, and a reflective sheet, a light guide plate, an optical film layer, and a backlight source respectively disposed in the frame 1. Frame body 1 can be the indisputable frame of gluing, and the indisputable frame of gluing includes the iron frame that encloses by diapire, lateral wall and fixes the gluey frame at the iron frame lateral wall inboard. The back of the frame body 1, namely the back of the iron frame, is divided into an FPC attaching area and a non-FPC attaching area according to the use requirement.
The display panel comprises an upper polarizer, a TFT substrate, a CF substrate, a lower polarizer and liquid crystal clamped between the TFT substrate and the CF substrate. The TFT substrate is fixed to the top of the frame 1. And the front surface of the TFT substrate is provided with a driving IC and an FPC2 connected with the driving IC and bonded to the TFT substrate. The FPC2 is led out from the TFT substrate, bent from the side of the frame 1 of the backlight module, extended to the back of the frame 1 and bonded to the frame 1, and then extended from the back of the frame 1 to be connected to the main circuit board of the mobile terminal. At this time, on the back surface of the frame 1 of the backlight module, an area for attaching the FPC2 is an FPC attachment area, and an area excluding the FPC attachment area is a non-FPC attachment area.
A heat-conductive double-sided adhesive tape 4 may be disposed in the FPC attachment area of the frame 1, so that the FPC2 is fixed to the frame 1 through the heat-conductive double-sided adhesive tape 4, and the heat-conductive double-sided adhesive tape 4 also performs a heat-conductive function. Therefore, the FPC attaching area of the frame body 1 also has a heat dissipation function, the heat dissipation effect of the integrated touch display module is improved, and the product performance is improved.
The thermally conductive double-sided adhesive tape 4 may be provided in various ways. In one example, as shown in fig. 2, the heat conductive double-sided tape 4 includes a second graphite sheet 41 and a double-sided tape body 42 wrapped outside the second graphite sheet 41, the FPC2 and the frame body 1 are adhered by the double-sided tape body 42, heat dissipation is achieved by the second graphite sheet 41, and the heat conductive double-sided tape is simple in structure and convenient to process and manufacture.
A piece of double-sided tape body 42 may be disposed on both sides of the second graphite sheet 41, respectively. The two double-sided adhesive tape bodies 42 have the same size and shape, and the area of the two double-sided adhesive tape bodies 42 is larger than that of the second graphite sheet 41. After the double-sided adhesive tape body 42 is adhered to both sides of the second graphite sheet 41, the double-sided adhesive tape body 42 protrudes from the second graphite sheet 41, and then the portions of the double-sided adhesive tape body 42 protruding from the second graphite sheet 41 are adhered together to form the thermally conductive double-sided adhesive tape 4.

So set up, avoid the possibility of persisting the air between two double faced adhesive tape bodies 42 as far as possible, improve two double faced adhesive tape bodies 42's bonding fastness, on the basis of guaranteeing two double faced adhesive tape bodies 42 bonding fastness, increase second graphite flake 41's area as far as possible simultaneously, for example, each position width that surpasss second graphite flake 41 of two double faced adhesive tape bodies 42 can be no longer than 2mm to improve the radiating effect in the attached district of FPC.
The shape of the thermally conductive double-sided adhesive tape 4 may be specifically set as required. And the FPC attachment area may not be entirely provided with the thermally conductive double-sided adhesive tape 4. For example, the thermally conductive double-sided tape 4 has a regular rectangular shape.

The non-FPC attachment region of the frame body 1 may be entirely attached with the first graphite sheet 3, or may not be entirely attached with the first graphite sheet 3. In one example, a first graphite sheet 3 is attached to a non-FPC-attached region of the housing 1 near one end of the driver IC. First graphite flake 3 is anomalous integral type structure, has all pasted first graphite flake 3 in the attached district of non-FPC of this end, and is equipped with the hole of dodging of FPC2 on first graphite flake 3.
