Abstract
Embodiments of the present invention relate to a liquid crystal grating and a control method thereof, and a 3D touch display panel. The liquid crystal grating, comprises: upper and lower substrates; a liquid crystal layer, arranged between the two substrates; a plurality of strip-shaped electrode groups, parallel to each other and arranged side by side, and formed on a surface of the upper substrate facing the liquid crystal layer, each of the electrode groups including first and second comb-shaped touch electrodes separated by a strip-shaped region, comb teeth of the first and second touch electrodes being opposite to each other, and an included angle between extending directions of the strip-shaped region and the electrode group being an acute angle; first and second comb-shaped grating electrodes, formed on a surface of the lower substrate facing the liquid crystal layer, the first and second grating electrodes being arranged in an interdigital shape.
