Embodiment Construction
[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0039] figure 1 A method for realizing color projection display provided by an embodiment of the present invention is shown, including:
[0040] S101, loading displacement gratings in different directions into the color image to be projected and displayed to obtain a preprocessed color image;
[0041] S102. Process the preprocessed color image using a superpixel algorithm to obtain a hologram of the color image, where the hologram includes each color component of the color image;
[0042] S103, loading the hologram onto the digital micromirror device, and incident the incident light to the digita...

The invention is suitable for the technical field of projection display and provides an implementation method for color projection display. The method comprises the following steps: displacement gratings in different directions are loaded into a color image to be projected and displayed, and a preprocessed color image is obtained; the preprocessed color image is processed with a super pixel algorithm, and a hologram of the color image is obtained and comprises each color component of the color image; the hologram is loaded onto a digital micromirror device, incident light is incident on the digital micromirror device, and reflected light obtained after the incident light is reflected by the digital micromirror device enters a 4-F optical imaging system, and the reflected light contains hologram information; the 4-F optical imaging system combines all color components in the hologram, and a reproduced color image with different color gray scale information is obtained. According to thereproduced color image obtained by the embodiment, the gray scale information is fuller and clearer than the image obtained with a color wheel method, and the trouble of the color wheel is avoided.
Description
technical field [0001] The invention belongs to the technical field of projection display, and in particular relates to a method for realizing color projection display, a display system and a display device. Background technique [0002] The color projection display realized by the traditional method generally uses the method of color wheel or liquid crystal light valve. The method of color wheel needs to realize the color display through the rotation of the color wheel, and the liquid crystal light valve needs to switch the liquid crystal unit independently. [0003] In the prior art, the color projection display is realized through the color wheel, and the obtained gray scale information of the reproduced color image is not full and clear enough, and at the same time, the operation of realizing the color projection display through the color wheel is cumbersome. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a ...
