One-dimensional integrated imaging display method of LED screen based on combined discrete grating

Abstract

A one-dimensional integrated imaging display method for an LED screen based on a combined discrete grating belongs to the technical field of free stereoscopic display. The invention designs a true three-dimensional display method for an LED display screen based on a combined discrete cylindrical lens grating. Firstly, the viewpoint images are obtained through real shots or virtual models, and are displayed on the LED display panel after being processed by the stereogram synthesis algorithm. The combined discrete cylindrical lens grating and the dual-angle holographic diffusion sheet are placed in sequence in the appropriate position in front of the display panel. By designing and matching each Various parameters of the device to achieve the best viewing effect. By designing a combined discrete cylindrical lens grating and using a double-angle holographic diffuser, the present invention realizes a three-dimensional display with continuous parallax, dense viewpoint, wide viewing angle and high definition, eliminates the discrete effect between pixels of the LED display screen, and solves the problem of Due to the small viewing angle of a single viewing area in the traditional lenticular lens grating stereoscopic display, the stereoscopic display effect is better than the traditional one-dimensional integrated imaging display method.

[0002] As a hot technology, 3D stereoscopic display technology has attracted the attention of a large number of researchers at home and abroad. Various research institutions have invested a lot of manpower and material resources in research and exploration, and have proposed a variety of stereoscopic display solutions, which are widely used in the current market. Most of the 3D display devices use the principle of binocular parallax, and need to wear corresponding glasses or head-mounted devices to achieve stereoscopic display. , will produce dizziness and discomfort, and long-term viewing may even cause harm to health. Therefore, free stereoscopic display technology without auxiliary equipment has become the 3D display method that people pursue.

Since the sub-pixels of the LED display are discrete monochromatic light-emitting diodes, the modulation through the cylindrical lens grating will aggravate this discrete phenomenon, resulting in such as Figure 5 The black stripes shown affect the overall stereoscopic display effect
