Abstract
A touch screen comprises a first substrate, a second substrate and a third substrate sequentially stacked. A first sensing layer is provided on a first surface of the second substrate opposing to the third substrate, and a second sensing layer is provided on a surface of the third substrate opposing to the second substrate. The second substrate provided with the first sensing layer and the third substrate provided with the second sensing layer constitute a touch unit for sensing a touch signal, and the second substrate and the first substrate constitute a display unit for displaying.
