The material that first conductive layer and the second conductive layer are selected by tradition only with transparent material expand to all properly
Conductive material；When metal material selected by conductive material, resistance can be substantially reduced and reduce touch screen
Energy consumption.
Above-mentioned polarisation-the filtration module 60 with touch controllable function is bilayer conductive structure, it is not necessary to carries out bridging and sets
Meter, is substantially reduced task difficulty.
Use above-mentioned polarisation-filtration module 60, can reduce liquid crystal display (LiquidCrystalDisplay,
LCD) signal disturbing to touch-control effect.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for this area
Those of ordinary skill for, without departing from the inventive concept of the premise, it is also possible to make some deformation and
Improving, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended
Claim is as the criterion.
