Naked eye three-dimensional image display device and method

Abstract

The invention discloses a naked eye three-dimensional image display device and method. The device comprises a signal acquisition module, a stereoscopic signal module, a display screen, an infrared distance measurement sensor, a control module and a grating drive module. The display screen is connected with the signal acquisition module, the stereoscopic signal module, the control module and the grating drive module through a data bus. The infrared distance measurement sensor is connected with the control module and the grating drive module. According to the method, the infrared distance measurement sensor is utilized to acquire distance signals between a user and a liquid crystal slit grating, the control module controls the interval between the liquid crystal slit grating and a two-dimensional liquid crystal displayer according to the distance signals, the grating drive module controls the state of the liquid crystal slit grating according to the distance signals, then, the displayer displays three-dimensional images, and the user can see the three-dimensional images at different distances from the liquid crystal slit grating.

Description

technical field [0001] The invention belongs to the field of electronic technology, and further relates to a naked-eye three-dimensional image display device and method in the field of photoelectric display technology. The invention can be used for displaying naked-eye three-dimensional images. Background technique [0002] At present, the most common naked-eye 3D display technology is grating 3D display technology. The grating 3D display made according to the grating 3D display technology has attracted much attention due to its advantages of simple structure, low cost and good performance. However, the existing grating three-dimensional display requires the user to be in a specific position to enjoy the best three-dimensional display effect, and cannot automatically adjust according to the distance between the user and the display screen to ensure that the user can watch the best three-dimensional display effect. If you are not in a specific position, you cannot watch a b...

AI Technical Summary

Problems solved by technology

Although the system architecture is simple and easy to implement, there are still shortcomings: the best viewing distance for users to watch 3D images is fixed, and it is not suitable for viewing 3D images at places farther or closer than the best viewing distance.

In addition, although the patent application method can prompt the user to move, there are still shortcomings: due to the large degree of freedom of user movement, it is difficult to ensure that the user accurately moves to the best viewing position

Although this device solves the problem that the user must be at a specific distance from the display screen, it still has the disadvantage that multiple displays are required due to the complex structure, resulting in a large resource overhead.

In addition, although the patent application method solves the problem of separation of 3D stereo signals, there are still shortcomings: the depth of field processing method is too cumbersome, and the real-time performance of 3D stereo signals is difficult to guarantee
