Claim 6:
7. A color filter substrate, comprising a base substrate, the color filter substrate further comprising:
a plurality of grating structures, disposed at a side of the base substrate, configured to generate polarized light;
a sensor unit, disposed at a side of the base substrate, configured to generate an electric current signal after irradiated by a laser; and
a switch unit, disposed at a side of the base substrate as the same as the sensor unit and connected to the sensor unit, configured to receive the electric current signal and allow the electric current signal to pass through the switch unit in response to the switch unit being in a switched-on state,
wherein the plurality of grating structures, the sensor unit and the switch unit are disposed on the color filter substrates
wherein the sensor unit is a thin-film transistor and at least comprises a first gate electrode, a first source electrode and a first drain electrode, each of the grating structures comprises a first grating structure and a second grating structure, the second grating structure stacks on a corresponding first grating structure, a material of the first grating structure and a material of the first gate electrode are a same material and belong to a same film layer, and a material of the second grating structure and a material of the first source electrode or the first drain electrode are a same material and belong to a same film layer.
