Problems solved by technology

For example, on a self-illuminating transparent screen or a reflective transparent screen with a black transparent display, a near-black color cannot be displayed, and a near-white color cannot be displayed on a light-blocking transparent screen with a white transparent display.
[0010] 2) It is impossible to change the transparency arbitrarily while keeping the color unchanged
[0011] 3) Cannot display the transparent colors of nature, such as the texture of glass and water

Abstract

The invention provides a true color alpha full-channel display device and method. The device comprises a first display unit and a second display unit, wherein the second display unit is arranged at the rear part of the first display unit in parallel in the watching direction. The first display unit is used for displaying a color channel and comprises a self-luminous layer and a first TFT layer, the first TFT layer is arranged at the rear part of the self-luminous layer in parallel in the watching direction, and the first TFT layer is used for controlling the color and brightness of the self-luminous layer. The second display unit is used for displaying a transparent alpha channel, comprises a first polaroid, a liquid crystal layer, a second TFT layer and a second polaroid which are arranged in parallel in the watching direction, and is used for controlling the alpha channel. According to the method, any transparent and opaque true color alpha full-channel display can be physically realized, and transparency and opacity which can be randomly displayed in any color can be realized.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a true-color alpha full-channel display device and a true-color alpha full-channel display method. Background technique [0002] In computer graphics, each image point can be expressed by four parameters of RGBA, where RGB represents the color channel, and A (also known as alpha value, alpha value) represents the transparency channel (also known as alpha channel, alpha channel). However, the alpha channel only exists in theory and graphics calculation at present, and there is no display device that can physically realize the alpha channel. [0003] Most of the current display technologies are opaque displays. [0004] Even existing transparent displays cannot physically implement an alpha channel. The existing transparent display technology can only present black transparent display or white transparent display. [0005] Black transparent display, such as a s...
