Claim 0:
1. A touch panel, comprising:
a display module;
a package cover plate, placed on a light-emitting side of the display module;
a second polarizer, placed on a side of the package cover plate, which is comparatively far from the display module;
wherein the display module comprises a display screen and a first polarizer placed on a side of the display screen, which is close to the package cover plate;
wherein a first frame glue is placed between the package cover plate and the display module, and the first frame glue, the package cover plate and the display module form a cavity; a first liquid crystal (LC) is filled in the cavity; the first liquid crystal comprises a plurality of first liquid crystal molecules, and orthogonal projections of light axes of some of the first liquid crystal molecules intersect a polarization direction of the first polarizer;
wherein a polarization direction of the second polarizer is perpendicular to the polarization direction of the first polarizer,
wherein a twisting pitch of the first liquid crystal is much larger than a wavelength of light of the display module.
