Problems solved by technology

However, in the prior art, when the lens structure cooperates with the 2D display to form a stereoscopic image display device, display unevenness, such as black and white stripes, Moiré fringes, color shift, etc., will occur, and these display unevenness will affect the stereoscopic image. Observation will cause interference, and in severe cases, stereoscopic images may not be seen clearly

Embodiment 1

[0033] In the technical solution provided by Embodiment 1, within one cycle of the lens plate 13, the X-axis coordinate values ​​of multiple pixel units 10 in two columns repeat aperiodically. The X-axis coordinate values ​​of multiple pixel units 10 are shifted to a certain extent, which solves the dark stripes caused by the fact that all the X-axis coordinate values ​​of a column of pixel units are the same or appear periodically in the prior art, and improves the display effect .

[0034] In other embodiments, the length of one cycle of the semi-cylindrical lens of the lens plate can also be 4 times, 8 times, or other positive even multiples of the length of a cycle of the pixel unit. The more viewpoints there are, the user can observe the stereoscopic display effect from multiple viewpoints. However, as long as the X-axis coordinate values ​​of multiple pixel units repeat non-periodically within one period of the lens plate, the effect of suppressing the occurrence of dar...

Embodiment 2

[0045] In the stereoscopic image display device provided by the first method of the second embodiment, each pixel unit in a row of pixel units has different X-axis coordinate values, so black and white stripes do not appear in one cycle of the lens plate 23 .

[0046] A second black matrix 22 is arranged between two adjacent columns of pixel units. For the convenience of calculation, the length of the pixel unit in the X-axis direction is M, including the length of the second black matrix 22 in the X-axis direction.

[0047] In the arrangement of pixel units, from the first pixel unit to the nth pixel unit, the X-axis coordinate values ​​of the plurality of pixel units can be shifted by 0.28 μm in sequence, that is Figure 5 As shown, as the X-axis coordinate value of the pixel unit increases sequentially, its Y-axis coordinate value also increases sequentially, and a column of pixel units presents an upward-right sloping trend. can also be like Figure 6 As shown, it is a sc...

Embodiment 5

[0123] The stereoscopic image display device provided by Embodiment 5 can solve the above problem of color shift. For details, please refer to Figure 17 , Figure 17 An array of color sub-pixel units 50 with 9 rows and 8 columns is shown, the length of each color sub-pixel unit 50 is M in the X-axis direction, and H is the length in the Y-axis direction.

[0124] The color sub-pixel units 50 in the first column are three colors of R, G, and B, and the color sub-pixel units 50 are arranged at intervals, and the X of the same vertex of each color sub-pixel unit 50 in the first column of color sub-pixel units 50 The axis coordinate values ​​are all unequal, and the minimum X-axis coordinate value is x1, and the maximum X-axis coordinate value is x12, and 0≤x12-x1≤M. The arrangement of the second column to the twelfth column of color sub-pixel units is also the same as that of the first column of color sub-pixel units.

[0125] The first row of color sub-pixel units is row R, ...

Abstract

The invention provides a stereo image display device comprising multiple display units which are arranged in rows and columns. First black matrixes are arranged between adjacent display unit rows, and second black matrixes are arranged between adjacent display unit columns. The stereo image display device also comprises lens boards which are arranged to be corresponding to multiple pixel units. The lens boards are composed of multiple half-cylindrical lenses via arrangement. In an X-axis direction, one cycle length of the half-cylindrical lenses of the lens boards is positive even times than one cycle length of the display units. Besides, in one cycle of the lens boards, X-axis coordinate values of the multiple display units are non-periodically repeated. Adverse effects like black and white strips can be solved by the stereo image display device so that display effect is enhanced.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a stereoscopic image display device capable of improving display effect. Background technique [0002] The basic principle of stereoscopic display technology is to use the parallax of the left and right eyes of people to provide the display images to the left and right images of the left and right eyes respectively, and then mix them into a stereoscopic image by the observer's brain. [0003] In the prior art, stereoscopic display is mainly formed by convex lens technology. However, in the prior art, when the lens structure cooperates with the 2D display to form a stereoscopic image display device, uneven display will occur, such as black and white stripes, Moiré fringes, color shift, etc., which will affect the stereoscopic image. Observation will cause interference, and in severe cases, stereoscopic images may not be seen clearly. Contents of the invention [0004] The r...
