Embodiment 1

[0084] The grating is compatible with three resolutions: UHD (2160×3840), QHD (1440×2560), and FHD (1080×1920), that is, n=3, and the highest resolution is M 1 ×N 1 That is 2160×3840. First, the ratio of the total number of rows to the total number of columns for each resolution is:

[0085]

[0086] Therefore, the ratio of the total number of rows to the total number of columns of the three resolutions is a fixed value, which satisfies the conditions for switching between multiple resolutions. Subsequently, the total number and width of the grating units required by the grating are calculated. The calculation process of the total number Z of the grating unit is as follows:

[0087] First, the greatest common divisor A1=360 of the total number of rows and the greatest common divisor A2=640 of the total number of columns of the three resolutions are calculated by using the total number of rows and the total number of columns of each resolution. According to the formula (...

Abstract

The invention discloses a grating, a preparation method, a driving method and a naked-eye three-dimensional display system. The grating includes at least one simplest grating and a driving signal line, the simplest grating includes a plurality of grating units arranged in sequence, and the driving signal line is configured to transmit a driving signal to each of the grating units to drive the grating The unit is in a light-transmitting state or a light-blocking state, so that the simplest grating is driven into alternately arranged light-transmitting units and light-blocking units, and the widths of the light-transmitting units and the light-blocking units are different according to different driving signals . Therefore, the grating can make the display system compatible with multiple resolutions, and can realize the switching of multiple resolutions in the display screen of the same size, thereby reducing the development cost.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a grating, a preparation method, a driving method, and a naked-eye three-dimensional display system. Background technique [0002] With the development of display technology, three-dimensional stereoscopic display is gradually popularized. Through the three-dimensional display technology, the user can make the picture three-dimensional and realistic, and is no longer limited to the plane of the screen. The realization of three-dimensional stereoscopic display is mainly to use a series of optical methods to make people's left and right eyes produce parallax to receive different pictures. At present, 3D display technology is developing rapidly, and it is mainly used in public business occasions, as well as display devices such as mobile phones, which can greatly improve the level of human-computer interaction and enrich the functions of mobile terminals such as mobile phones. Th...
