DETAILED DESCRIPTION

[0021] 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.

[0022] A touch display module that prevents the upper iron frame from being seen, referring to Figure 1, including a touch screen 10, a display screen 20 and a backlight 30 arranged in sequence from top to bottom. An upper iron frame 31 is arranged on the periphery of the backlight 30. The edges of the upper end of the upper iron frame 31 are all recessed inward to form a receiving groove 311 for receiving the display screen 20 with the backlight 30. The display screen 20 is received in the receiving groove 311, and the upper surface of the display screen 20 contacts the bottom of the upper end of the upper iron frame 31.

[0023] Reference Figure 1 , the touch screen 10 is located above the upper iron frame 31, and a foam glue 40 for bonding and fixing is provided between the touch screen 10 and the upper iron frame 31. The foam glue 40 is attached to the bottom of the touch screen 10 in a square shape, and the side of the foam glue 40 away from the touch screen 10 is fixed to the upper end surface of the upper iron frame 31. Since the window opening of the upper iron frame 31 in the prior art is smaller than the window opening of the foam glue 40, when the touch display module is obliquely viewed in a normal viewing angle, the frame of the upper end surface of the upper iron frame 31 can be seen. Therefore, in this embodiment, the window opening of the foam glue 40 is smaller than the window opening of the upper iron frame 31, the foam glue 40 covers the upper end surface of the upper iron frame 31, and the inner edge of the foam glue 40 exceeds the inner edge of the upper iron frame 31 by a distance. By making the foam glue 40 cover the entire upper end surface of the upper iron frame 31, and the coverage area of ​​the foam glue 40 is larger than the upper end surface area of ​​the upper iron frame 31, so that the upper end surface of the upper iron frame 31 is covered by the foam glue 40, the frame of the upper iron frame 31 cannot be seen when the touch display module is viewed at a normal viewing angle, so that the overall appearance of the touch display module is better, and the bonding area of ​​the foam glue 40 is increased, so that the touch screen 10 and the upper iron frame 31 are more reliably bonded.

[0024] Further, refer to Figure 1 The inner edge of the foam glue 40 is 0.5mm-1mm away from the inner edge of the upper iron frame 31.

[0025] Further, refer to Figure 1 The foam glue 40 is set in black, and the black foam glue 40 has a better covering effect and has the function of shading and covering the upper iron frame 31.

[0026] Further, refer to Figure 1 The display screen 20 includes a display area 21 in the middle and a non-display area 22 arranged outside the display area 21. The display area 21 is the area where the display screen 20 displays content, and the non-display area 22 does not display content. The foam glue 40 is arranged along the outer circumference of the display area 21 of the display screen 20. The coverage of the foam glue 40 is located in the non-display area 22. The foam glue 40 is at a certain distance from the display area 21 of the display screen 20 to prevent the foam glue 40 from affecting the normal display of the display screen 20.

[0027] Reference Figure 1The touch screen 10 includes a cover plate 11, an optical adhesive layer 12 and a sensing glass 13 which are sequentially arranged from top to bottom. The foam adhesive 40 is arranged between the sensing glass 13 and the upper iron frame 31 to adhere and fix the touch screen 10 and the upper iron frame 31. The optical adhesive layer 12 between the cover plate 11 and the sensing glass 13 has a bonding and fixing function to fix the cover plate 11 and the sensing glass 13.

[0028] Reference Figure 1 An ITO layer 131 is disposed on the upper surface of the sensing glass 13 , and the ITO layer 131 is used to enable the touch screen 10 to have a touch function.

[0029] Reference Figure 1 A black ink layer 14 is provided on the lower surface of the cover plate 11. The black ink layer 14 is used to make the frame of the touch display module appear black, so that when the touch display module is in the off state, it presents an integrated black effect, making the appearance of the touch display module better.

[0030] Reference Figure 1 The black ink layer 14 is disposed on the lower surface of the cover plate 11 along the circumferential direction of the cover plate 11, and the black ink is screen-printed on the lower surface of the cover plate 11 in a square shape. The opening of the black ink layer 14 is smaller than the opening of the foam glue 40, and the coverage of the black ink layer 14 is larger than the coverage of the foam glue 40. The black ink layer 14 covers the foam glue 40, thereby enhancing the covering effect on the upper iron frame 31.

[0031] Reference Figure 1 The black ink layer 14 is arranged relative to the non-display area 22 of the display screen 20. The black ink layer 14 is arranged along the outer circumferential direction of the display area 21 of the display screen 20, and the inner edge of the black ink layer 14 is flush with the outer edge of the display area 21 of the display screen 20. The black ink layer 14 makes the non-display area 22 of the display screen 20 appear black, thereby preventing the light of the backlight 30 from being emitted from the non-display area 22 of the display screen 20 to affect the display effect of the display screen 20.

[0032] Reference Figure 1 The touch display module sets the window of the foam glue 40 to be smaller than the window of the upper iron frame 31, and the window of the foam glue 40 is larger than the window of the black ink layer 14, so that the foam glue 40 can cover the frame of the upper iron frame 31, and the black ink layer 14 further enhances the covering effect. Therefore, when the touch display module is used, the frame of the upper iron frame 31 cannot be seen when looking inward from any viewing angle, so that the overall appearance effect is better.

[0033] 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.
