Abstract

The invention discloses a glass-free three dimensional display apparatus and a control method of the same. The glass-free three dimensional display apparatus includes a display panel, a liquid crystal grating, a processor and an image collector, wherein the display panel is used for outputting frames; the liquid crystal grating is arranged between the display panel and a viewer for separating the visual frames of double eyes of the viewer; the image collector is used for acquiring the first current viewed information and the second current viewed information, and sending the first current viewed information and the second current viewed information to the processor; and the processor is used for adjusting the width and / or position of the light transmission area of the liquid crystal grating according to the first current viewed information, and adjusting the output frame of the display panel according to the second current viewed information and the adjusted width and / or position of the light transmission area of the liquid crystal grating. The glass-free three dimensional display apparatus realizes that crosstalk does not occur in the 3D image viewed by the viewer when the position of the viewer is changed, and can realize the anti-peeping function at the same time.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a naked-eye three-dimensional display device and a control method thereof. Background technique [0002] The working principle of three-dimensional (3D) display technology is: for the same scene, the left eye and right eye of the viewer receive images respectively, and the distance between the two eyes of the viewer in the horizontal direction (that is, the interpupillary distance, about 65mm) makes There is a slight difference in the viewing angles of the two eyes. Due to this difference, the images observed by the left and right eyes of the viewer will also be slightly different. This difference is called "binocular parallax", while the left and right eyes The observed images with differences constitute a pair of "stereoscopic image pairs", and the "stereoscopic image pairs" form a stereoscopic effect after being fused by the visual cortex of the brain. [0003] The current s...
