[0031] The touch screen provided in the embodiment of the present application includes a connected receiving layer 110 and a transmitting layer 120. The receiving layer 110 includes a first layer body 111, a receiving electrode 112, and a first alignment component 113. The first alignment component 113 includes a first laser alignment label 1131 and a first reference ring 1132.

Then, the transmitting layer 120 is placed on the receiving layer 110, and the coordinates of the second laser alignment label 1231 are obtained. The receiving layer 110 and the transmitting layer 120 are aligned using these two coordinates. By setting the first reference ring 1132 and the second reference ring 1232, the receiving layer 110 and the sending layer 120 can be aligned. Combined with the setting of the first laser alignment label 1131 and the second laser alignment label 1231, the precise alignment of the receiving layer 110 and the sending layer 120 can be guaranteed, thereby ensuring the touch accuracy of the touch screen.

[0032] It is understood that the first and second laser alignment labels 1131 and 1231 are engraved using a laser (with an accuracy of 0.02±0.008mm), which minimizes deformation and distortion. It is important to note that during the engraving process, no residue should remain on the edges of the first and second laser alignment labels 1131 and 1231.
