Embodiment 1
[0029] A compressed light field display system based on liquid crystal light valve, such as figure 1 As shown, this embodiment includes a computer 1, a driving circuit 2, a high-speed DLP projector 3, and a liquid crystal light valve array 4; the core component of the high-speed DLP projector 3 is DMD, which is a set of digital micro-mirror arrays as a light modulating Spatial light modulator. The output of the computer 1 is connected to the input of the drive circuit 2. The output of the drive circuit 2 is divided into two, one is connected to the input of the high-speed DLP projector 3, and the other is connected to each layer of the liquid crystal light valve array 4 Valve connection.
[0030] The liquid crystal light valve array 4 includes 6 layers of liquid crystal light valves, and the 6 layers of liquid crystal light valves are arranged parallel and equally spaced along the projection direction of the high-speed DLP projector 3, and each layer of liquid crystal light valv...

The invention relates to the technical field of light field display, in particular to a compressed light field display system based onliquid crystal light valves and alight field compression algorithmof the compressed light field display system. The compressed light field display system includes a driving circuit and a liquid crystal light valve array, the liquid crystal light valve array includes N liquid crystal light valve layers arranged side by side, the N liquid crystal light valve layers are arranged in the projection direction of a high-speed DLP projector, the output end of a computer is connected with the input end of the driving circuit, the output end of the driving circuit is divided into two ways, one way is connected with the input end of the high-speed DLP projector, and the other way is connected with each liquid crystal light valve of the liquid crystal light valve array; and the computer compresses three-dimensional frame images into N two-dimensional sub-frame images and inputs the N two-dimensional sub-frame images into the driving circuit, the driving circuit outputs the N sub-frame images to the high speed DLP projector, the high-speed DLP projector projectsthe N two-dimensional sub-frame images to a liquid crystal light valve array layer in turn, the driving circuit cooperatively controls the corresponding liquid crystal light valve array layer in thescattering state, and thus a three-dimensional image is formed in a view field.
Description
Technical field [0001] The present invention relates to the technical field of light field display, in particular to a compressed light field display system based on a liquid crystal light valve and a light field compression algorithm thereof. Background technique [0002] The persistence effect of human vision refers to the fact that when the image seen by the human eye disappears when the object is moving fast, the human eye can continue to retain the image, and the retention time is about 0.05s to 0.2s. The light field display technology introduces the concept of light field into the stereoscopic display. Light field refers to the amount of light passing through a point in space in different directions. When people observe objects, they feel the intensity of light distributed in space. [0003] The existing light field display technologies are mainly integrated imaging technology, multi-projection light field display technology and compressed light field display technology. In...
