Abstract: Disclosed are a TOF depth sensing module and an image generation method. The TOF depth sensing module includes an array light source, a beam splitter, a collimation lens group, a receiving unit, and a control unit. The array light source includes N light emitting regions. The collimation lens group is located between the array light source and the beam splitter. The control unit is configured to emit light. The collimation lens group is configured to perform collimation processing on beams. The beam splitter is configured to perform beam splitting processing on beams. The receiving unit is configured to receive reflected beams of a target object. By means of the TOF depth sensing module, high spatial resolution and a high frame rate can be implemented in a process of scanning the target object.

Abstract: This application discloses a display method and a display control apparatus. The display system includes a projection screen, the projection screen includes a transparent substrate and a liquid crystal film covering the transparent substrate, and the liquid crystal film includes a plurality of liquid crystal cells. The display method includes: obtaining a to-be-displayed image; determining a target liquid crystal cell from the plurality of liquid crystal cells based on locations of pixels in the to-be-displayed image; setting a status of the target liquid crystal cell to a scattering state, and setting a status of a non-target liquid crystal cell to a transparent state, where the non-target liquid crystal cell is a liquid crystal cell in the plurality of liquid crystal cells other than the target liquid crystal cell; and displaying a projection image of the to-be-displayed image on the target liquid crystal cell.
