Abstract

The embodiment of the invention provides a naked eye 3D display device and a control method, which relates to a display technology field. The naked eye 3D display device comprises a 2D display unit and a liquid crystal slit grating. The 2D display unit comprises a pixel array. Each pixel in the pixel array comprises a plurality of different colors of sub-pixels arranged alternately in a first direction. The liquid crystal slit grating is arranged on one side of the display face of the 2D display unit and is opposed to the display face of the 2D display unit. The liquid crystal slit grating comprises a first grating polarizer, a first grating substrate, a liquid crystal layer and a second grating substrate, wherein the first grating polarizer, the first grating substrate, the liquid crystal layer and the second grating substrate are successively stacked. Electrode layers are arranged on the first grating substrate and the second grating substrate. In different control modes, the liquid crystal slit grating forms a grating stripe which extends in the first direction or extends in a direction at a predetermined angle to the first direction, so as to avoid color edges in a direction perpendicular to the first direction.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a naked-eye 3D display device and a control method. Background technique [0002] Among various stereoscopic display technologies, naked-eye 3D display technology has become a hotspot in the research of 3D display technology due to the convenience of not needing other auxiliary equipment and its advantages in application. Glasses-free 3D stereoscopic display devices are also widely used in the field of personal consumer goods, such as small-sized glasses-free 3D mobile phones, small and medium-sized glasses-free 3D tablets, and the like. [0003] Among the various technologies for naked-eye 3D display, liquid crystal lens (LC lens) technology and birefringent lens array (Birefringent Lens Array) technology have high brightness characteristics in 3D display, and their development prospects are promising. The yield rate is low due to various reasons such as the manufactur...
