Problems solved by technology

This display structure has the following disadvantages: (1) the additional parallax barrier makes the display device relatively thick, which is not conducive to the thinning of the display device; (2) the high shading degree of the black grating makes the resolution of the naked-eye 3D display device low

Abstract

The invention discloses a naked-eye 3D display device. The naked-eye 3D display device comprises: an upper substrate, a lower substrate, a pixel lamination layer and a liquid crystal layer, the upper substrate and the lower substrate are arranged oppositely, the upper substrate is a color filter substrate, and the lower substrate adopts For the thin film transistor array substrate of COA technology, the pixel stack and liquid crystal layer are sandwiched between the upper substrate and the lower substrate, and the pixel stack is used for partial light shielding. The present invention replaces the parallax barrier by COA technology and R / G / B pixel stacking technology. The shading degree of the grating generated by the stacked pixels is lower than that of the black grating, which improves the resolution of the naked-eye 3D display device and improves the display effect of the naked-eye 3D display device.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, the present invention is a naked-eye 3D display device and a manufacturing method thereof. Background technique [0002] When human eyes observe objects, because the two eyes are in different horizontal positions, that is, there is interpupillary distance, the entity images observed by the left eye and the right eye are different, because the entity images observed by the left eye and the right eye are both There is a parallax between them, so that people can perceive the three-dimensional changes of objects, which is the so-called 3D (three dimensional) visual principle. [0003] According to the above principles, 3D display technology came into being. It uses the left and right of the human eyes to receive different images, and then the brain superimposes and regenerates the image information to form a display with front-back, up-down, left-right, far-near, etc. ...
