Problems solved by technology

[0003] At present, the slit grating is the most mature technology for naked-eye three-dimensional effect, and it is widely used. However, due to the interference between the periodically arranged display pixels and the periodic structure of the slit grating, it is easy to form color or black and white moiré fringes. The existence of moiré fringes affects the stereoscopic display effect, destroys the integrity of the image, and affects the viewing experience of the viewer
[0004] At present, the main method to solve moiré is to tilt the slit grating at a certain angle, thereby weakening the moiré, making it almost impossible for human eyes to distinguish; although the inclined slit grating can weaken the moiré phenomenon to a certain extent, but due to the slit The grating blocks the light, and the edge of the display panel changes from a light-emitting area to a non-luminous area. Therefore, the color of the moiré pattern that appears on the edge of the display panel becomes darker and thicker, resulting in an unnatural transition from the display area to the edge, showing obvious jagged. This seriously damages the integrity of the image and affects the viewing effect

Abstract

The invention relates to the technical field of display, and discloses a stereoscopic display device, including a display panel and a slit grating disposed opposite to the display panel, wherein the display panel includes a display area and a black matrix disposed at the edge of the display area, the display area includes display units in array arrangement, the slit grating includes a plurality ofspaced apart first electrodes and a microelectrode structure, and the microelectrode structure is disposed between the ends of the adjacent two first electrodes and used for dispersing the light output at the edge of the display area so as to weaken the saw-tooth phenomenon appearing at the edge of the stereoscopic display device in a stereoscopic display mode, so that the image can be displayednormally, and the visual experience of the user is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a stereoscopic display device. Background technique [0002] The naked-eye stereoscopic display has become an important stereoscopic display technology because of its all-round display power and shocking power and the advantages of not needing to wear special glasses when viewing. Glasses-free stereoscopic displays mainly include slit grating autostereoscopic displays and lenticular slit grating autostereoscopic displays. The stereoscopic display is based on the light splitting principle of slit grating. The light through each pixel of the display panel can enter the left or right eye of the viewer respectively, and the two eyes can see different pictures, thereby generating a sense of space based on the principle of stereo fusion. [0003] At present, the slit grating is the most mature technology for naked-eye three-dimensional effect, and it is widely used. However, due to t...
