Stereoscopic display unit and production method thereof

Abstract

The invention discloses a stereoscopic display unit and a production method thereof. The stereoscopic display unit comprises a display panel, a display control unit and a grating lens, the display panel comprises a first row of sub-pixels and a second row of sub-pixels arranged adjacently along the column direction, the display control unit acquires multiple viewpoint images which are divided into a first group of viewpoint images and a second group of viewpoint images, further the first row of sub-pixels is controlled to periodically display content of each viewpoint image in the first group of viewpoint images, the second row of sub-pixels is controlled to periodically display content of each viewpoint image in the second group of viewpoint images, the grating lens comprises a first row of lens units and a second row of lens units arranged adjacently along the column direction, the first row of lens units and the second row of lens units respectively cover the first row of sub-pixels and the second row of sub-pixels, the lens units in the first row of lens units and the lens units in the second row of lens units are staggered mutually along the row direction, and the stagger amount is smaller than one sub-pixel period. By the means, moire can be eliminated, and the problem of crosstalk between the adjacent pixel units can be solved.

Description

technical field [0001] The invention relates to the field of portable electronic equipment, in particular to a stereoscopic display device and a manufacturing method thereof. Background technique [0002] Currently, display technology has developed from 2D display to 3D display. The existing naked-eye stereoscopic display device is mainly developed based on binocular parallax. Its main working principle is to guide two images with a certain parallax to the left eye and right eye of the observer respectively through a lens array or a parallax barrier, so that the observer can observe The user feels the three-dimensional effect. The current glasses-free 3D display technology can be realized by using a parallax barrier, a lenticular lens, or a directional backlight. The stereoscopic display device in the prior art generally adopts a lenticular lens array, in order to solve the problem of uneven brightness distribution so that observers can observe images with uniform brightne...

AI Technical Summary

Problems solved by technology

Stereoscopic display devices in the prior art generally use a lenticular lens array, the purpose of which is to solve the problem of uneven brightness distribution so that observers can observe images with uniform brightness distribution

[0003] figure 1 It is a structural schematic diagram of a stereoscopic display device in the prior art, such as figure 1 As shown, taking 8 viewpoints as an example, the grating lens includes 8 lens units periodically arranged along the row direction, so the resolution in the row direction is seriously sacrificed, only 1 / 8 of the original, because the grating lens and the pixel arrangement of the display panel have high The similarity of the frequency, that is, the grating lens group and the black matrix on the display panel have an equal periodic structure, which makes it easy to form a beat and produce moiré
