Abstract

Embodiments of the present invention provide a display device and a control method thereof. The display device includes: a display unit, a light adjustment unit, a polarizer, and a phase delay unit. The display unit includes a plurality of pixel units arranged in an array. The light adjustment unit includes a first electrode layer, a liquid crystal layer and a second electrode layer, wherein the first electrode layer includes a first electrode, and the second electrode layer includes a plurality of strip-shaped second electrodes arranged in parallel. The light adjustment unit, the polarizer and the phase delay unit are sequentially arranged along the light emitting direction of the display unit. The phase delay unit is configured such that polarized light from adjacent rows of pixels of the display unit transmitted through the phase delay unit has different rotation directions. The light adjustment unit can be used to realize a controllable liquid crystal grating for switching between 2D display and 3D display. In addition, the viewing angle of the 3D display can also be enlarged.

Description

technical field [0001] The present invention relates to display technology, in particular to a display device and a control method thereof. Background technique [0002] With the increasing development of information and image display technology, display technology has been applied more and more in various fields. In some fields, for example, in the medical field, higher requirements are put forward for the clarity of information display, visual range, and the like. [0003] Most of the existing display devices are based on common two-dimensional (2D) display screens, which lack layering and three-dimensionality. Conventional medical three-dimensional (3D) display devices mainly use polarized light 3D display technology. Polarized 3D displays usually have the problem of a small vertical viewing angle and a narrow vertical viewing area. [0004] There is room for improvement in existing display devices.
