In other embodiments, the material of the protective cover 20 may also be transparent plastic, acrylic, or any other material with a certain light transmittance that can protect the structure to which it is attached.
The ink layer 30 is formed on the attaching surface by screen printing or transfer printing. The transmittance of the ink layer 30 is low, and the touch display screen 50 is divided into a visible area 60 and a non-visible area 70.
Transparent insulating glue layer 40 is located the laminating surface and is extended to on printing ink layer 30, and transparent insulating glue layer 40 is optical cement, and bonding strength is high for bond protection cover plate 20 and touch-control display screen 50. Moreover, the transparent insulating adhesive layer 40 is colorless and transparent, and the light transmittance is higher than 90%, so that the display effect of the touch display screen 50 is not affected.
The touch display screen 50 includes a display module 100 and a touch module 200, and the display module 100 and the touch module 200 are connected together by gluing.
The display module 100 has an operation area 102 and a frame area 104 surrounding the operation area 102, the area of the operation area 102 is equal to or slightly smaller than the area of the visible area 60, the operation area 102 is mainly used for displaying characters, images and the like, the frame area 104 fixes the operation area 102, and the frame area 104 can be provided with a driving circuit and other structures used for being associated with the operation area 102. The display module 100 has a first surface 110 and a second surface 120 disposed opposite to each other, and a side surface connected between the first surface 110 and the second surface 120, the side surface including a first side surface 130 and a second side surface 140 adjacent to each other.
The touch module 200 includes a touch body 210 and a touch line 220 electrically connected to the touch body 210. The touch body 210 includes a main body portion 212 and a bending portion 214 integrally formed. The main body 212 is located between the protective cover 20 and the first surface 110, the main body 212 is connected to the protective cover 20 through the transparent insulating glue layer 40, and the main body 212 is attached to the first surface 110 in a gluing manner.

And because the line width and the line distance of the touch control line 220 do not need to be reduced, the electric signal can be stably conducted, so that the area of the visible area 60 is increased, the stable conduction of the electric signal is ensured, and the good touch control sensitivity of the touch control display screen 50 is further ensured.
In the present embodiment, the touch module 200 further includes a light shielding layer 230, wherein the light shielding layer 230 is located in the non-visible region 70, extends from the main body portion 212 to the bending portion 214, and covers a portion of the touch circuit 220.

Further, the bent portion 214 can also extend to the second surface 120, and an end of the bent portion 214 disposed on the second surface 120 exceeds the light shielding layer 230. Due to the light transmittance of the bending portion 214, when the touch body 210 is bent, the bending condition of the touch line 220 can be observed from the side of the bending portion 214 away from the light shielding layer 230, so as to prevent the touch line 220 from being broken due to excessive bending. Moreover, the touch body 210 can be prevented from wrapping the display module 100 too tightly to cause the display module 100 to bend and deform.
In other embodiments, the bending portion 214 may be bent only to the side of the display module 100 and does not extend any more; or the bent portion 214 extends to the second surface 120, and one end of the bent portion on the second surface 120 is flush with the end surface of the light shielding layer 230.

The touch pins 224 are used for binding the flexible circuit board, the touch pins 224 are distributed on the main body portion 212 and the second bending portion 218, the light shielding layer 230 covers the touch lead 222 and a part of the touch pins 224, and the part of the touch pins 224 exposed out of the light shielding layer 230 is used for binding the flexible circuit board.
Referring to fig. 1 and fig. 3, the first bending portion 216 extends to the second surface 120. For the structure corresponding to the first bent portion 216, the operation region 102 has an interface 106 connected to the frame region 104 and parallel to the first side surface 130, and the light shielding layer 230 includes an inner end surface 231 disposed on the main body 212, and the inner end surface 231 is located between the interface 106 and the first side surface 130. Therefore, the light shielding layer 230 can be prevented from covering the image displayed by the display module 100. In the present embodiment, the distance between the inner end surface 231 and the interface surface 106 is set to be greater than 0.15mm in consideration of possible tolerance at the time of mounting.

Specifically, in the manufacturing process, before the light shielding layer 230 is printed, the size of the light shielding layer 230 is preset with reference to the position of the first side surface 130 of the display module 100, and the position of the first outer end surface 232 is determined, so that the first outer end surface 232 and the first side surface 130 in a finished product can be aligned and positioned accurately, and therefore the touch lead 222 covered by the light shielding layer 230 is prevented from being stretched excessively, or the bent touch lead 222 is prevented from being too large in size and cannot be completely attached to the display module 100. When the projection of the first outer end surface 232 on the second surface 120 coincides with the first side surface 130, the first outer end surface 232 of the light shielding layer 230 is ideally aligned with the first side surface 130 of the display module 100.

By aligning and positioning the second outer end surface 236 of the light shielding layer 230 with the second side surface 140 of the display module 100, specifically, in the manufacturing process, before printing the light shielding layer 230, the size of the light shielding layer 230 is preset by referring to the position of the second side surface 140 of the display module 100, and the position of the second outer end surface 236 is determined, so that the second outer end surface 236 and the second side surface 140 in a finished product can be aligned and positioned more accurately, and the touch pins 224 covered by the light shielding layer 230 are prevented from being stretched excessively, or the bent touch pins 224 are prevented from being too large in size and cannot be completely attached to the display module 100. When the projection of the second outer end surface 236 on the second surface 120 coincides with the second side surface 140, the second outer end surface 236 of the light shielding layer 230 is ideally aligned with the second side surface 140 of the display module 100. The distance between the projection of the second outer end surface 236 on the second surface 120 and the second side surface 140 may be set to be within ± 1mm in consideration of the tolerance possible in actual manufacturing.
The light-shielding layer 230 further includes a second outer surface 238 disposed parallel to the second side surface 140 and away from the touch lines 220.
