Abstract

The invention belongs to the field of display devices, and provides a light conversion device, a preparation method thereof and an infrared imaging device. According to the light conversion device provided by the present invention, a photosensitive member and a light-emitting member are arranged side by side on a substrate and connected through a gain member, thereby realizing the gain effect of the device, so that the device has higher light-sensing light-emitting efficiency. Due to the compact structure, small size and light weight of the device, the requirements for portable imaging of thedevice are met. Because each pixel has a simple structure and low process difficulty, each pixel is suitable for the existing printing preparation process. The cost is reduced, and a large area of replication can be achieved.

Description

technical field [0001] The invention belongs to the field of display devices, and in particular relates to a light conversion device, a preparation method thereof, and an infrared imaging device. Background technique [0002] Infrared imaging technology has been widely used in medical, military, night vision, satellite and civilian fields, and has always been a hot spot in scientific research. In recent decades, researchers have proposed imaging devices that can convert low-frequency infrared light to higher-frequency near-infrared or high-frequency visible light. [0003] The usual infrared-visible conversion imaging device (or photon energy up-conversion device) is a device based on silicon materials and photomultiplier tubes. The device is large in size. When it is used as a wearable night vision device, it has high power consumption and poor portability. Shortcomings. In order to improve the aforementioned shortcomings, researchers have turned to film-based night visio...
