[0021] A display screen 100 for reusing after a touch function fails, a display assembly 10, a cover plate 11, a liquid crystal screen 12, a display FPC 13, an upper polarizer 14, a lower polarizer 15, an insulating adhesive layer 20, and a touch binding PIN position 21. DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0023] This application proposes a display screen 100 that can be reused after the touch function fails. Figure 1 and Figure 2, including: a display component 10 and an insulating adhesive layer 20. A touch binding PIN position 21 is provided at one end of the display component 10, and the touch binding PIN position 21 is electrically connected to the display component 10. The insulating adhesive layer 20 is conductive and insulated, and the insulating adhesive layer 20 is sealed and fixed on the touch binding PIN position 21, so as to prevent the failed TP touch function of the display screen 100 that is reused after the touch function fails from affecting the display function, so that the display screen 100 that is reused after the touch function fails can be applied to products that do not require a touch function, and then the display screen 100 that is reused after the touch function fails and is facing scrapping can be reused, thereby improving the utilization rate of materials and thus improving economic benefits. Preferably, the insulating adhesive layer 20 is a UV adhesive layer or a blue glue, and the blue glue is acrylic glue, which is made of an electrically insulating material.

[0024] Furthermore, the thickness of the insulating adhesive layer 20 is less than 0.3 mm, so as to prevent the insulating adhesive layer 20 from being higher than the touch binding PIN position 21, which is not conducive to assembling a display screen 100 that has a failed touch function and is reused in a product.

[0025] Furthermore, the thickness of the insulating adhesive layer 20 is 0.22 mm.

[0026] In one embodiment, please refer again to Figure 2 The display assembly 10 includes a cover plate 11, a liquid crystal screen 12, a display FPC 13, an upper polarizer 14, and a lower polarizer 15. The cover plate 11, the upper polarizer 14, the liquid crystal screen 12, and the lower polarizer 15 are stacked in sequence, and one end of the display FPC 13 is bound to the edge of the liquid crystal screen 12. The upper polarizer 14 and the lower polarizer 15 filter the light in certain directions for the liquid crystal screen 12, so that the picture of the display assembly 10 is clearer. Preferably, the cover plate 11 is a TP cover plate.

[0027] Furthermore, the display assembly 10 also includes a backlight component, which is arranged on a side of the display liquid crystal screen 12 away from the cover plate 11 to provide lighting for the display assembly 10 so that the image formed by the liquid crystal screen 12 of the display assembly 10 is presented.

[0028] Furthermore, the display assembly 10 further includes OCA glue, which has excellent light transmittance. The cover plate 11 is bonded to the upper polarizer 14 through the OCA glue, which enhances the fixing effect of the cover plate 11 and the display assembly 10, and does not affect the display effect of the display screen 100 that is reused after the touch function fails. Preferably, the four corners of the cover plate 11 are arc-shaped, which enhances the aesthetic effect and prevents the human body from hitting the cover plate 11 and causing greater physical damage.

[0029] In addition, one end of the display FPC 13 is bound to the edge of the liquid crystal screen 12, and the other end is bent to the backlight component side. The display FPC 13 overlaps the length and width of the backlight component and the display assembly 10, which can reduce the length of the display screen 100 that is reused after the touch function fails, making the structure more compact. A component area is set on the display FPC 13, and the component area is used to solder electronic components.

[0030] 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.
