Referring to fig. 1 and 2, a touch screen convenient for a sticker frame includes: the touch screen comprises a glass cover plate 100, an optical colloid 200, a touch sensing layer 300, an optical adhesive tape layer 400, a screen module 500 and a reinforcing adhesive 600, wherein one side surface of the optical colloid is completely attached to the touch sensing layer, one side surface of the optical colloid, which is far away from the touch sensing layer, is attached to the glass cover plate, the optical adhesive tape layer is of a square structure, the optical adhesive tape layer is attached to the touch sensing layer and between the screen modules, and the reinforcing adhesive is attached to the edge positions between the screen modules and the glass cover plate. The glass cover plate 100 is used for attaching the optical adhesive 200, the touch sensing layer 300, and the like; the optical colloid 200 is used for adhering the touch sensing layer 300 to the glass cover plate 100, and the touch sensing layer 300 is used for realizing a touch control function; the optical tape layer 400 is used for attaching the screen module 500 to the touch sensing layer 300; the screen module 500 is used for realizing display and protecting the touch layer; the reinforcing glue 600 is used for sealing between the screen module and the glass cover plate.

Therefore, the optical adhesive tape layer with the square-shaped structure is arranged between the touch sensing layer and the screen module, compared with the existing double-sided adhesive tape, the optical adhesive tape layer with the square-shaped structure has the advantages of better compactness of the adhered material, higher strength, good waterproof and steam-proof effects, convenience for a user to adhere, no shadow generated after adhering, good display effect and lower cost compared with the method for adhering the optical adhesive tape layer with the square-shaped structure comprehensively; in addition, after assembly, black reinforcing glue is arranged at the edge position between the screen module and the glass cover plate, so that the sealing performance is better, and the visual effect is further improved.

In this embodiment, the thickness of the optical tape layer is 25um to 200 um. Further, the thickness of the optical adhesive tape layer is 50 um-175 um. Preferably, the thickness of the optical tape layer is 100 um. So, can realize both can laminating, can strengthen the display effect again to compare in traditional double faced adhesive tape, the thickness of this optical adhesive tape is very thin, makes the air bed thinner, and the display effect is good, thereby in addition, can also reduce the reflection of light by a wide margin, reduce and see through light loss and promote luminance, the display effect of reinforcing screen lets the picture more penetrating, compares in traditional frame and pastes the screen and still possess more ultra-thin characteristic.

Referring to fig. 3, the optical tape layer 400 includes two transverse tapes 410 and two vertical tapes 420, which together form a square structure. It should be noted that the two transverse tapes 410 and the two vertical tapes 420 are crossed with each other to form a square structure, and then are attached between the touch sensing layer 300 and the screen module 500, so that the screen module 500 can be stably installed on the touch sensing layer 300.

Referring to fig. 4, a protrusion is disposed on the connecting end of the transverse adhesive tape, a groove is disposed on the connecting end of the vertical adhesive tape, and the protrusion is embedded in the groove. In this way, the stability of the connection can be improved.

Referring to fig. 5, the transverse adhesive tape and the vertical adhesive tape are both in a trapezoidal structure, and the transverse adhesive tape is connected with the vertical adhesive tape. Thus, the stability of the structure can be improved.

Referring to fig. 6, the connecting end of the transverse adhesive tape has a first avoiding gap, the connecting end of the vertical adhesive tape has a second avoiding gap, and the first avoiding gap is matched with the second avoiding gap. In this way, the stability of the connection can be improved.

Referring to fig. 7, the connecting ends of the transverse adhesive tape and the vertical adhesive tape are both provided with saw-toothed structures, and the saw-toothed structures of the transverse adhesive tape and the vertical adhesive tape are clamped with each other.
