Display device, control method thereof, and display control device

Abstract

The invention discloses a display device and a control method and a display control device thereof. The display device comprises a display panel and a liquid-crystal control panel, wherein the display panel is used for displaying images and emitting a linearly-polarized light; the liquid-crystal control panel comprises a first liquid-crystal unit and a second liquid-crystal unit which are alternately arranged, liquid-crystal molecules in the first liquid-crystal unit and the second liquid-crystal unit are arranged along a preset direction, therefore when the linearly-polarized light passes through the first liquid-crystal unit and the second liquid-crystal unit, the polarization direction of the linearly-polarized light is not changed; the first liquid-crystal unit is provided with a first electrode pattern layer for controlling liquid-crystal molecules to deflect a first preset angle under an applied first preset voltage; and the second liquid-crystal unit is provided with a second electrode pattern layer for controlling liquid-crystal molecules to deflect a second preset angle under an applied second preset voltage. According to the technical scheme of the invention, two-dimensional images, double-view images and three-dimensional images can be displayed, and three-dimensional images can be displayed three dimensionally in a way of circular polarization, therefore, the display effect of three-dimensional images can be effectively improved.

Description

technical field [0001] The present invention relates to display technology, in particular to a display device, a control method thereof, and a display control device. Background technique [0002] With the development of display technology, especially three-dimensional (three-dimensional, 3D) display has become the direction of display development, and display devices with 3D image display functions have been recognized by consumers. Three-dimensional display technologies mainly include naked-eye and glasses-type Two types, among them, the audience realizes three-dimensional image display by wearing polarizing glasses (polarizing glasses), which is a kind of glasses-type three-dimensional display technology. [0003] figure 1 is a schematic diagram of a 3D display device that performs three-dimensional display using linearly polarized light. Such as figure 1 As shown, the 3D display device mainly includes: a display panel 10, a patterned half-wave plate 20 and linear pola...

Problems solved by technology

[0005] However, the existing 3D display devices have the following defects: (1) the existing 3D display devices can only perform three-dimensional display or dual-view display, but cannot perform two-dimensional display, that is, three-dimensional or dual-view and two-dimensional display cannot be realized on the same display device. The switch between two-dimensional display cannot meet the viewing needs of users; (2) When using circularly polarized light for three-dimensional display or two-dimensional display, two kinds of diaphragms, patterned half-wave plate and λ / 4 wave plate, are required. The diaphragm manufacturing process is difficult and the realization method is complicated
