The system sequentially comprises a transparent substrate, a transparent electrode, a hole transport layer, a quantum dot light-emitting layer, an electron transport layer, a mesh electrode, an insulating dielectric layer, a P-type doped layer,a quantum dot infrared photoelectric conversion layer, an N-type doped layer, a rear collecting electrode, an infrared detection structure power supply and a visible light-emitting structure power supply from bottom to top, wherein the transparent electrode is connected with a positive pole of the visible light-emitting structure power supply; the mesh electrode is connected with negative poles of the visible light-emitting structure power supply and the infrared detection structure power supply; and the rear collecting electrode is connected with the positive pole of the infrared detection structure power supply. A detection structure is integrated with a display structure, so that direct coupling of display pixels through a detection unit is achieved and an incident infrared image is directly converted into a visible light image; and the electrodes do not need to be pixelated during preparation, so that the preparation process is greatly simplified and the preparation cost is reduced.

Description

technical field [0001] The invention relates to a method and system structure for infrared image detection and formation of visible light image display, in particular to an infrared detection-visible light display integrated system based on semiconductor quantum dots, a preparation method and an imaging method. Background technique [0002] Infrared detection and imaging have important applications in security monitoring, medical diagnosis, national security, and target guidance. Because the wavelength of infrared photons is beyond the sensitive area of ​​human eyes, human eyes cannot directly observe infrared images. In the process of infrared detection and imaging, it is necessary to use detectors or sensor arrays to convert the received infrared photon signals into electrical signals, and through signal transmission and information processing, the electrical signals are converted into visible light images through the display. [0003] At present, most commercial infrared...
