A spatial light modulator and a stereoscopic display device

Abstract

The application discloses a spatial light modulator and a stereoscopic display device. The spatial light modulator comprises a plurality of pixel rows, the pixel row comprises a plurality of pixels arranged along a first direction, and the pixel comprises a pixel opening; along the first direction, the plurality of pixel openings are arranged in a transverse period length period; the size of the pixel opening along the first direction is a transverse opening size; the ratio of the transverse opening size to the transverse period length is a transverse opening rate, denoted as β1, and satisfies: β1 < 1. By reasonably setting the transverse opening rate, the high-order diffraction intensity is reduced, and the crosstalk risk is reduced.
