Description

Technical Field

[0001] The utility model relates to the technical field of integrated touch display, in particular to an integrated touch display structure facilitating identification of component protection paper. Background Art

[0002] In an integrated touch display structure, most of the used circuit boards are FPCs (flexible printed circuits). To achieve a good electromagnetic shielding effect, usually a copper foil is pasted on the IC chip bonded to the liquid crystal display screen in the integrated touch display structure up to the FPC, and at the same time, a ground copper exposed area is added on the FPC12 to be bonded with the copper foil to form an electromagnetic shielding layer; since the surface of the components on the FPC is not GND (ground terminal), in order to reduce the influence, a layer of component protection paper is covered on the components of the FPC. In order to prevent problems such as oxidation, short circuit, scratching and contamination on the surface of the copper foil, a layer of copper foil insulating paper is also added on the surface of the copper foil. The copper foil insulating paper and the component protection paper are made into a whole and attached to the incoming material to improve production efficiency. Since the component protection paper will be covered by the copper foil after being attached to the FPC components, it is impossible to identify whether there is a problem of missing pasting of the component protection paper. In addition, since a shielding film is usually added on the surface of the existing FPC, the appearance of the shielding film is black, and the commonly used component protection paper is yellow transparent or green transparent. After the component protection paper is attached to the surface of the component, against the background of the black shielding film, the component protection paper becomes less obvious, that is, more difficult to be identified, and further causes difficulty in identifying the component protection paper.

[0025] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0026] Please refer to Figure 1 、 Figure 2, Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in Figure 7 , an integrated touch display structure facilitating the identification of component protection paper includes: a liquid crystal display screen 100 and an electromagnetic shielding member 200. An IC chip 110 and an FPC 120 are bonded to the lower end of the liquid crystal display screen 100, and a component area 121 is provided on the FPC 120. The electromagnetic shielding member 200 includes a copper foil protection paper 210, a copper foil body 220, and a component protection paper 230 which are stacked in sequence. After the electromagnetic shielding member 200 is respectively attached to one side of the IC chip 110 and the FPC 120, the component protection paper 230 covers the component area 121. Avoidance through holes 240 which are aligned with each other are respectively formed on the copper foil protection paper 210 and the copper foil body 220. The avoidance through holes 240 are located in the area where the component protection paper 230 is provided, so that the component protection paper 230 is exposed. A shielding film 122 is provided on the surface of the FPC 120, and an identification support block 122a is provided on the shielding film 122. The position of the identification support block 122a corresponds to the avoidance through hole 40.

[0027] It should be noted that forming the avoidance through holes 240 which are aligned with each other on the copper foil protection paper 210 and the copper foil body 220 respectively means that an avoidance through hole 240 is formed on the copper foil protection paper 210, and an avoidance through hole 240 is also formed on the copper foil body 220. The avoidance through hole 240 on the copper foil protection paper 210 is aligned with the avoidance through hole 240 on the copper foil body 220, and the avoidance through holes 240 are located in the area where the component protection paper 230 is provided, so that the component protection paper 230 is exposed, facilitating the observation of whether the component protection paper 230 is missed during pasting. Meanwhile, an identification support block 122a is provided on the FPC shielding film 122. The color of the component protection paper 230 is set off by the identification support block 122a, making the transparent yellow / transparent green component protection paper 230 more obvious, thus facilitating the quick identification of whether there is a problem of the component protection paper 230 being missed during pasting. In this embodiment, the integrated touch display structure 10 facilitating the identification of component protection paper further includes a cover plate 300. The cover plate 300 is attached to and connected with the liquid crystal display screen 100 through an optical adhesive. Further, the integrated touch display structure 10 facilitating the identification of component protection paper further includes a backlight module 400. The backlight module 400 is disposed on the side of the liquid crystal display screen 100 away from the cover plate 300, and the backlight module 400 is used to provide a light source for the display of the liquid crystal display screen 100. Specifically, a copper exposed area 123 is further provided on the FPC 120, and the copper foil body 220 is in contact connection with the copper exposed area 123, thereby forming an electromagnetic shielding layer.

[0028] Preferably, the identification backing block 122a is a white ink backing block, that is, using white as the background color of the component protection paper 230 can make the color of the transparent yellow / transparent green component protection paper darker, more obvious, and easier to identify, so that it is easier to quickly identify whether the component protection paper 230 has a missing problem.

[0029] Preferably, the thickness of the white ink support block is 15 μm.

[0030] Preferably, the electromagnetic shielding component 200 also includes IC insulating paper 250, which is arranged on a side of the copper foil body 220 away from the copper foil protective paper 210, and the IC insulating paper 250 is attached to a side of the IC chip, and the IC chip is insulated and protected by the IC insulating paper 250.

[0031] Preferably, the four edges of the copper foil protection paper 100 are aligned with the four edges of the copper foil body 200. This ensures that the copper foil protection paper 100 protects the copper foil body 200. For example, the copper foil protection paper 100 and the copper foil body 200 can be processed by integral die-cutting.

[0032] In one embodiment, reference may be made to Figure 3 As shown, the avoidance through hole 240 is located in an area away from the component area. Because the avoidance through hole 240 is opened on the copper foil body 200, it has a better electromagnetic shielding effect on the components in the component area, so it is necessary to make the avoidance through hole 240 located in an area away from the component area, for example, the avoidance through hole 240 is located near the sharp corner end of the component protection paper 230.

[0033] Specifically, the liquid crystal display screen 100 includes an upper polarizer 130, an upper glass 140, a lower glass 150 and a lower polarizer 160 stacked in sequence, a binding area 151 is provided at the lower end of the lower glass 150, and the IC chip 110 and the FPC 120 are respectively bound and arranged on the binding area 151.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
