Description
Technical Field
The present invention relates to the display of three-dimensional moving images, and more particularly to stereoscopic three-dimensional displays.
Background
Three-dimensional (3D) movies have been popular in commercial theaters for decades, but the need for viewers to wear polarizers is a key factor that limits their appeal to certain genres and audiences. With the push for the success of 3D movies, 3D television became a hot spot of research several years ago. However, this technology eventually failed commercially and 3D television is no longer produced. One of the key reasons for the failure due to 3D television is that it is often necessary to wear polarized or active shutter glasses in order for the two eyes of the viewer to see different images and thus achieve depth perception.
In view of the above, the underlying basis of 3D display technology is a display technology that allows a viewer to view 3D moving images without the need to wear glasses or any other form of filter or attachment. Despite the advances made in this field of research in laboratory environments, the final images suffer from drawbacks such as limited viewing angle, small image size and low spatial resolution. Accordingly, it is desirable to alleviate one or more of the difficulties of the prior art, or at least to provide a useful alternative.
The LED dot matrix screen is composed of LEDs (light emitting diodes), displays characters, pictures, animation, video and the like by turning on and off the lamp beads, is a display device with all parts modularized, and generally comprises a display module, a control system and a power supply system. The LED dot matrix display screen is simple to manufacture and convenient to install, and is widely applied to various public places such as automobile station reporters, advertising screens, bulletin boards and the like. The LED three-dimensional array can be used for three-dimensional display and has the advantages of simple manufacture, vivid three-dimensional effect, 360-degree visual angle, modulatable resolution ratio and the like. Is one of the most promising stereoscopic display technologies.
Disclosure of Invention
Perovskite quantum dots are promising as next-generation solid light sources and displays due to their high photoluminescence quantum yield, narrow emission bandwidth, tunable wavelength covering the entire visible spectrum and compatibility with flexible/stretchable electronics.

Detailed Description
The invention relates to a three-dimensional photoelectric display based on an inorganic perovskite quantum dot LED, which comprises a main display component, an LED component and a control component, wherein as an implementation mode, the display component adopts three-dimensional glass, the three-dimensional glass is a carrier of the perovskite quantum dot LED, the glass is transparent, and images can be displayed at a full view angle. The glass is in a three-dimensional shape and can be round or square. As another embodiment, the glass may be replaced by a transparent colloid, such as silica gel or transparent plastic, which can also achieve the object of the present invention.
The LED component is a quantum dot part, and the all-inorganic perovskite quantum dot CsPbBr3The array is uniformly distributed in the three-dimensional glass. Each quantum dot forms a micro perovskite quantum dot LED. The quantum dot LED is connected with an external power supply through an invisible wire. Each quantum dot LED can independently emit light, and the brightness is controllable.
The control component is formed by connecting a perovskite quantum dot LED wire with an external integrated chip and a computer through electrodes and is used for receiving and controlling images. Under the control of a computer and an external integrated chip, the quantum dot LED can be bright or dark and has three colors of red, green and blue. The animation graph in the computer can be displayed on the quantum dot LED in the glass body through the chip so as to realize the three-dimensional display effect.
The present invention has an array of light sources aligned with the array of quantum dots such that the LED light emitted by each light source is transmitted through a corresponding one of the modulation regions. An image signal representing a three-dimensional moving image is received by a control means and processed to generate a signal for light control.
The key of the three-dimensional display comprises the steps of uniform and ordered distribution of quantum dot LEDs, lead-out of wires, preparation of electrodes, integrated circuit processing, program design and animation production.
The programming is the key to the control of the quantum dot LED. Since three-dimensional stereoscopic display is more complex than two-dimensional LED display, the procedure requirements are higher. The design of the program is also more complex and difficult. The key of the program is to orderly regulate and control each quantum dot LED to realize the three-dimensional display effect.
Animation is the basis of the three-dimensional display. The invention can realize simple animation display, and the animation design can be completed by common animation software. The computer is used for converting the animation graph into an instruction of an integrated chip to control the brightness and the switch of the quantum dot LED in the three-dimensional glass.
The invention is further described below with reference to the accompanying drawings.

The 3D display includes a glass member 001, a quantum dot LED member 002, and an electrode connecting member 003, and controls an image signal input. The image is generated by a computer and is input into a circuit board through a calculation program, and the circuit board controls the on-off and the brightness of each quantum dot LED.
Due to their nanoscale, 3D display 100 produces holographic images having approximately 360 degrees of full viewing angle. A 128 x 128 array can be formed by precision machining, producing high resolution stereoscopic images with spatial dimensions of about 20cm to 50 cm. As shown in fig. 1, a stereoscopic cone image is displayed on the display.
The uniform distribution of the quantum dot LED array is schematically shown in fig. 3. The quantum dot LED is embedded in the three-dimensional glass, and the three-dimensional glass can be replaced by a transparent plastic body or a silicon body. The quantum dot LEDs are uniformly and integrally arranged, the distance between the quantum dot LEDs can be adjusted according to the required resolution, and the resolution from micron level to millimeter level is realized.
By this method, full-color stereoscopic display can be realized.
The invention also provides a method for realizing the three-dimensional photoelectric stereoscopic display, which comprises the steps of designing an image by a computer, converting the image into an electric signal by a program, and regulating and controlling the brightness of quantum dot LEDs in the glass body to realize the three-dimensional stereoscopic display effect.
