Line 2241. The first conduction line 2231 forms a first conduction area (not shown), and the second conduction line 2241 forms a second conduction area (not shown). There are a plurality of the first conductive lines 2231, a plurality of the first conductive lines 2231 are arranged horizontally at intervals, the second conductive lines 2241 have a plurality of, and a plurality of the second conductive lines 2241 are spaced apart longitudinally. Arranged, the orthographic projections of the plurality of first conductive lines 2231 and the plurality of second conductive lines 2241 in the thickness direction of the touch screen 22 are staggered horizontally and vertically. The first non-conducting area 223a is the area where the first electrode layer 223 is not provided with the first conductive line 2231, and the second non-conducting area 224a is the area where the second electrode layer 224 is not provided with the second conductive line 2231.

The second conductive line 2241 includes a plurality of parallel second touch lines 22411 and second connecting lines 22412, and the second connecting lines 22412 are connected between every two adjacent second touch lines 22411. Each of the first touch wires 22311 is provided with four orthographic projections of the second touch wires 22411 at intervals around the orthographic projection of the touch screen 22, and each of the second touch wires 22411 is arranged at intervals.

Specifically, the antenna 221 is disposed in the first non-conducting area 223 a, and the antenna 221 is disposed opposite to the second conductive line 2241. During use, the first electrode layer 223 is close to the user relative to the second electrode layer 224, so that when the antenna 221 transmits or receives signals, the signal does not need to pass through the second electrode layer 224, and In other words, the signal transmitted or received by the antenna 221 needs to pass through less media, that is, the less the signal is reduced, so that the signal strength transmitted or received by the antenna 221 is better. In addition, the antenna 221 and the second conductive line 2241 are disposed opposite to each other so that the antenna 221 has more space for disposing, which is convenient for disposing the antenna 221.

Of course, the size of each of the second conductive line 2241 and the metal mesh of the antenna 221 is 100 μm. In other embodiments, the size of each of the metal meshes of the first conductive line 2231, the second conductive line 2241, and the antenna 221 is 50-500 μm, or each of the metal meshes The size is 50 or 500μm.
