Description

Technical Field

[0001] The present invention relates to the field of display devices, and in particular to a full-channel true-color display device and method. Background Art

[0002] Transparent display technology is used in exhibitions and stage performances, but the existing transparent display technology can only present black transparent display or white transparent display. It has the technical defect of not being able to display transparent and opaque full colors arbitrarily, thus limiting its application in a wider range of fields.

[0003] Black transparent display is a self-luminous transparent screen or an image projected onto a transparent reflective medium. The closer the display content is to black, the more transparent it is, and the closer it is to white, the more opaque it is. White transparent display, such as a non-luminous light-blocking transparent screen, has a display medium that does not emit light itself, and requires a light source in the background to see the display content on the display surface. Its characteristics are that the closer the display content is to white, the more transparent it is, and the closer it is to black, the more opaque it is.

[0004] Due to the limitation of display principle, no matter black transparent display or white transparent display, it is impossible to present all colors arbitrarily transparent display. The transparency of the displayed image is related to the color, and the transparency changes with the color. The transparency cannot be changed arbitrarily while keeping the color unchanged. For example, on a black transparent self-luminous transparent screen or a reflective transparent screen, a near-black color cannot be displayed, and a white transparent light-blocking transparent screen cannot display a near-white color. In particular, the texture of glass and water cannot be displayed.
