Problems solved by technology

[0002] In the process of 3D display, it is necessary to provide left-eye images and right-eye images to the left and right eyes of the viewer, but due to various reasons, the left eye of the viewer sees a certain amount of content in the right image, and the right eye sees a certain amount of content. The content of the left eye will cause double image phenomenon (or called ghost image) in the 3D scene, that is, "crosstalk" occurs
The existence of crosstalk greatly affects the quality of 3D display

Embodiment 1

[0077] Embodiment 1: Slanted Lens Grating

[0078] 1. Model establishment

[0079] 1. Initial model

[0080] In this embodiment, a tilted lens grating is taken as an example. Certainly, the embodiment of the present invention adopts the stereoscopic display technical solution of the tilted lens grating, and may adopt a playback mode that is tracked according to the position of the viewer, or may adopt a fixed-point or fixed-point playback mode, and the embodiment of the present invention does not do Specific restrictions. Based on the above description, the lens grating can obviously be simplified as a slit grating model with aperture ratio δ=100%. The display units P1, P2, etc. can be sub-pixels, and the image display value (information value) can adopt RGB mode, then the display value L of the left eye view and the display value R of the right eye view satisfy: 0≤L, R≤255, Moreover, the RGB direction of the stereoscopic display device is horizontal, and it can also be RG...

Embodiment 2

[0159] Example 2: Vertical slit grating

[0160] In this embodiment, a vertical slit grating is taken as an example, and the projection period of the grating period on the pixel panel is an even multiple of the sub-pixel. At this time, if only the influence of the human visual experience law on crosstalk is considered, the calculation formula (1) can be converted into:

[0161] A=α|P-L| n +β|P-R| n ≥0 (6)

[0162] And by adopting a modeling and solving method similar to that in Embodiment 1, it can be obtained:

[0163] α = Tol 1 β = Tol 2

[0164] At this time, the calculation formula (6) can be embodied as:

[0165] A=Tol1|P-L| n +Tol2|P-R| n ≥0 (7)

[0166] 1. n=1 and α-β≠0

[0167] From the above calculation formula (7), it can be known that:

[0168] ...

Embodiment 3

[0178] Embodiment 3: Light-splitting glasses-type 3D technology

[0179] In this embodiment, the light-splitting glasses-type 3D technology is taken as an example. Assume that the light leakage rates of the left and right lenses of the glasses are both μ (0≤μ≤1), then according to the definition of the information ratio parameters S1 and S2 seen by the left and right eyes, without considering other light leakage factors, the display area in the left image of the display panel In any display unit in the display area, the information ratios corresponding to the left and right eyes are respectively S1=1-μ, S2=μ, while in any display unit in the display area on the right, the information ratios corresponding to the left and right eyes are respectively S1 =μ, S2=1-μ. At this time, if only the influence of the human visual experience law on crosstalk is considered, the calculation formula (1) can be converted into:

[0180] A=α|P-L| n +β|P-R| n ≥0 (8)

[0181] And by adopting a...

Abstract

The invention provides a stereoscopic display method. The stereoscopic display method comprises the steps that an interference value relevant to a display unit of at least one pair of images with parallax errors is acquired; the display unit is adjusted according to the interference value; the images with the parallax errors are displayed through the adjusted display unit. The invention further provides a stereoscopic display device. According to the technical scheme, a crosstalk phenomenon in the stereoscopic display process can be effectively relieved, and the stereoscopic display effect is optimized.

Description

technical field [0001] The present invention relates to the technical field of stereoscopic display, in particular to a stereoscopic display method and a stereoscopic display device. Background technique [0002] In the process of 3D display, it is necessary to provide left-eye images and right-eye images to the left and right eyes of the viewer, but due to various reasons, the left eye of the viewer sees a certain amount of content in the right image, and the right eye sees a certain amount of content. If the content of the left eye of the 3D scene is not displayed, it will cause double image phenomenon (or called ghost image) in the 3D scene, that is, "crosstalk" occurs. The existence of crosstalk greatly affects the quality of 3D display. [0003] Therefore, how to reduce the influence of crosstalk during the naked-eye 3D display process has become an urgent technical problem to be solved. Contents of the invention [0004] The present invention aims to solve at least...
