Abstract

The present disclosure relates to a display mode control device, a control method thereof, and a display device, and relates to the field of display technology. The display mode control device includes: a first substrate, including a plurality of lens units distributed in an array, and each lens unit is provided with a ring-shaped diffraction phase grating; a second substrate, arranged in a box with the first substrate; a liquid crystal layer, located on the first Between the substrate and the second substrate; the control electrode is used to form a preset electric field to control the deflection state of the liquid crystal molecules. The present disclosure can realize switching between a plane display mode and a virtual curved surface display mode.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a display mode control device, a control method thereof, and a display device. Background technique [0002] Traditional flat panel display devices have the advantages of being thin and light, saving physical space, etc., and have been widely used in the display field. However, due to its light distribution properties, from the position where the display is directly facing the human eyes to the two sides, the light intensity gradually becomes weaker as the viewing distance increases, resulting in poor visual experience for users. Especially for large flat panel display devices, this effect is particularly obvious. [0003] The embracing effect of the curved surface display can enhance the impact of the user's visual effect, thereby providing the user with a good visual experience. However, its disadvantage is that the physical bending engineering of the curved sur...
