Touch liquid crystal grating, 3d touch display device and driving method of touch liquid crystal grating

摘要

An embodiment of the present invention discloses a touch liquid crystal grating (1), its driving method and a 3D touch display device. The touch liquid crystal grating (1) comprises: a first substrate (101) and a second substrate (102); a liquid crystal layer (103); grating electrodes (104) located on the side of the first substrate (101) facing the liquid crystal layer (103) and extend along a first direction, each being located within each of strip-like regions (A) with spacing regions (B) being provided therebetween; touch driving electrodes (105), extending along the first direction and being located within the spacing regions (B) between adjacent strip-like regions (A); and touch sensing electrodes (106), extending along a second direction, wherein the first direction is different from the second direction, and when the plurality of grating electrodes (104) are electrified, liquid crystal molecules corresponding to each of the strip-like regions (A) are deflected, and liquid crystal molecules corresponding to each of the spacing regions (B) are not deflected.
