Embodiment 1

[0065] like image 3 , taking the cylindrical lens grating and the generation of 4 initial viewing areas as an example, along the transmission direction of the outgoing light from the pixels of the display screen 10, the spectroscopic device 20 is placed in front of the display screen 10, and based on the principle of light splitting, the initial viewing area V is generated op1 , V op2 , V op3 , and V op4 . When only the display screen 10 and the light splitting device 20 exist, the pixel P of the display screen 10 l+1 , P l+5 , P l+9 , P l+13 , ... constitute a pixel group in the initial view area V op1 Visible inside, pixel P l+2 , P l+6 , P l+10 , P l+14 , ... constitute a pixel group in the initial view area V op2 Visible inside, pixel P l+3 , P l+7 , P l+11 , P l+15 , ... constitute a pixel group in the initial view area V op3 Visible inside, pixel P l+4 , P l+8 , P l+12 , P l+16 , ... constitute a pixel group in the initial view area V op4 Visible i...

Embodiment 2

[0070]Using the timing controllable optical splitting device 20 and / or the timing controllable guiding device 30, at M adjacent time points at intervals of Δt / M, M groups of different optical splitting unit 20 and guiding unit 30 pairs appear in sequence. The guiding device 30 at each time point is composed of L groups of guiding substructures, and the guiding units of the guiding device 30 and the light-splitting devices of the light-splitting device 20 correspond one-to-one to form a light-splitting unit-guide unit pair. Then, more L×M guide viewport sets can be formed within the time Δt by means of time division multiplexing. like Figure 5 , taking L=2 and M=2 as an example. At the time point T within the time period T~T+Δt, similar to the process described in Embodiment 1, through L=2 guide substructures, two guide viewport sets are generated, the guide viewport set 1 and the guide viewport set 2. Then, at the time point T+Δt / 2 within the time period T˜T+Δt, the optica...

Embodiment 3

[0078] In the above system, a switching device 40 composed of N groups of controllable switching apertures can be further introduced. Similarly, along the transmission direction of the light emitted from the pixels of the display screen 10 , the light splitting device 20 is placed in front of the display screen 10 . The guiding device 30 and the switching device 40 are introduced. The guiding unit of the guiding device 30 and the respective constituent apertures of the switching device 30 are in real-time one-to-one correspondence with the light-splitting units of the light-splitting device 20. The unit and the guide unit form a beam splitting unit-guide unit pair. Each constituent aperture of the switching device 40 is divided into N groups, and within a time period of Δt, one of the N groups of apertures of the switching device 40 is turned on, and the beam splitting unit-guide unit pair corresponding to this group of apertures one-to-one is gated. Specifically, within the ...

Abstract

The present invention relates to the technical field of three-dimensional image display, and more particularly, to a small-pitch viewing zone guided three-dimensional display system and method. The system includes: a display screen, a light splitting device, a guiding device, a control unit, and optional switching devices, an aperture array, a tracking feedback unit and a quadrature gating control device. The light splitting device is used to guide the outgoing light of different groups of pixels on the display screen to be seen in different initial viewing areas; with the assistance of other system components, the built-in guiding device deflects the outgoing light from different pixel subsets of the pixel groups corresponding to each initial viewing area to Each corresponding guide viewport in a different guide viewport set. It is used to cover each guide view area set of the observer's different eyes, and the distance between adjacent guide view areas is not greater than the diameter of the observer's pupil. The small-pitch viewing area guided three-dimensional display system and method of the present invention can be presented through monocular multi-view, overcome focusing-convergence conflict, realize three-dimensional display that can be naturally focused, and improve three-dimensional visual comfort.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional image display, and more particularly, to a small-pitch viewing zone guided three-dimensional display system and method. Background technique [0002] Since it is difficult for two-dimensional display to express the depth information of the third dimension clearly and accurately, people have been working on the display technology that can display stereoscopic scenes—three-dimensional image display technology. Multi-view based on the principle of light splitting Figure 3 3D display technology is compatible with mainstream flat-panel displays and is currently the most widely used 3D display technology: through gratings and other light splitting devices, the light emitted from different groups of pixels on the display screen is guided to different viewing areas with equidistant distribution, so that different viewing areas can be seen. Each corresponding pixel group displays light i...
