The invention discloses a dual-display liquid crystal grating screen, a dual display control method and device, as well as a dual-display display. The dual-display display comprises a liquid crystal grating screen and a compensation screen attached to the liquid crystal grating screen, wherein the liquid crystal grating screen comprises multiple liquid crystal units and liquid crystal molecules arranged in the liquid crystal units in a mixed mode, the liquid crystal molecules are arranged from outside to inside from the approximately horizontal direction to the approximately vertical direction; and the compensation screen comprises compensation units arranged corresponding to the liquid crystal units, and the compensation units are used to compensate optical path differences of the light passing through the liquid crystal units. According to the technical scheme provided by the invention, the compensation screen attached to the liquid crystal grating screen can lead the dual-display liquid crystal grating screen to display a two-dimensional or three-dimensional picture, so that the two-dimensional and three-dimensional images can be played and displayed on the same display.
Description
technical field [0001] The invention relates to display technology, in particular to a dual-display liquid crystal grating screen, a dual-display control method and device, and a dual-display display. Background technique [0002] With the development of three-dimensional display technology, displays with three-dimensional image display functions have been recognized by consumers. Among them, the realization of three-dimensional display technology based on the principle of binocular parallax and light splitting is one of the commonly used three-dimensional display technologies. [0003] figure 1 It is a structural schematic diagram of a three-dimensional display using a cylindrical grating screen for three-dimensional display in the prior art. like figure 1 As shown, the three-dimensional display includes a two-dimensional display screen 10 and a cylindrical lenticular screen 20, wherein the cylindrical lenticular screen 20 is a sheet-shaped lenticular screen composed of a...
