A pointing backlight type autostereoscopic display system and display method thereof

Abstract

The invention discloses a directional backlight-type free stereoscopic display system and a display method thereof, and the system comprises a directional backlight module, a horizontal light collimation module, a display panel, a horizontal light control module, a vertical light diffusion device, and a central control module. The system controls the sequential emission of all backlight sources inthe backlight control module at different angles and the image refreshing corresponding to the display panel, employs all optical modules for the precise control of light, achieves the high-frequencyalternating in the sky to form a plurality of visual areas, and finally achieves the three-dimensional display effect at a big view angle.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a pointing backlight autostereoscopic display system and a display method thereof. Background technique [0002] The 3D display without wearing any equipment and with a high degree of reproduction has become an inevitable choice for the future of display technology. This technology is currently being used in more and more fields such as medical imaging, exhibition display, commercial display, military command, government emergency dispatch, and communication media. It has begun to play an important role, and it has become a new display solution vigorously developed by various countries. [0003] Autostereoscopic display technology based on directional backlight is a new type of display technology that can watch 3D images with naked eyes. The directional backlight display technology controls the direction of the light emitted by the backlight so that the screen image...

AI Technical Summary

Problems solved by technology

[0004] Although the existing autostereoscopic display technology based on directional backlight has no significant advantage of resolution loss, it also has obvious defects:

However, the real restoration of 3D objects and scenes requires dense viewpoints, so the existing technology cannot restore the real sense of space of the objects (such as the occlusion relationship of space, the front and rear parallax relationship), and the observer cannot see the difference between the restored objects or scenes. Angled images to achieve a visual sense of depth only at one angle

[0007] (3) The existing autostereoscopic display technology based on directional backlight can only provide viewers with a small range of viewing angles on the front of the system, but the real restoration of three-dimensional objects and scenes requires a larger 3D viewing angle to achieve
