LIQUID CRYSTAL GRATING, DISPLAY DEVICE AND DRIVE METHOD THEREOF

摘要

The present disclosure discloses a liquid crystal grating, a display device and a method of driving the display device. The liquid crystal grating comprises a first substrate, a second substrate disposed opposite to the first substrate, a liquid crystal layer arranged between the first substrate and the second substrate, a second transparent electrode layer formed on a side of the second substrate facing towards the first substrate, and a first transparent electrode layer formed on a side of the first substrate facing towards the second substrate; The present disclosure implements integration of a touch function and a two-direction autostereoscopic display function.

1. A liquid crystal grating, comprising:
a first substrate; a second substrate disposed opposite to the first substrate; a liquid crystal layer arranged between the first substrate and the second substrate; a first transparent electrode layer formed on a side of the first substrate facing towards the second substrate and comprising a plurality of transparent electrode strips in a first direction; and a second transparent electrode layer formed on a side of the second substrate facing towards the first substrate and comprising a plurality of transparent electrode strips in a second direction, the second direction being perpendicular to the first direction; wherein the transparent electrode strips in the first direction and the transparent electrode strips in the second direction are adapted to be driven by a stereoscopic display drive signal to enable the liquid crystal layer to form an grating structure in the first direction or the second direction; and wherein the plurality of transparent electrode strips in the first direction comprise a plurality of first touch signal lines, and the plurality of transparent electrode strips in the second direction comprise a plurality of second touch signal lines, the first touch signal lines and second touch signal lines being adapted to be driven by a touch drive signal to achieve touch positioning.
