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. The light conversion device provided by thepresent invention is formed by juxtaposing a photosensitive member and a light-emitting member on a substrate and connecting the photosensitive member and the light-emitting member through a first electrode. When the device is in operation, the photosensitive member converts input non-visible light signals into photogenerated electrons, and the photogenerated electrons are injected into the lightemitting member through a first electrode to drive the light-emitting member to emit visible light, so that the device has high light-sensing light-emitting efficiency. At the same time, due to the compact structure, small size and light weight of the device, the requirements for preparing a portable infrared imaging device are met. The preparation method of the light conversion device has simplepreparation process and is suitable for large-area preparation.

Description

Technical field [0001] The invention belongs to the field of display devices, and particularly relates to a light conversion device, a preparation method thereof, and infrared imaging equipment. Background technique [0002] Infrared imaging technology has important applications 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 used as a wearable night vision device, it has high power consumption and poor portability. Shortcomings. In order to improve the aforementioned shortcomings, researchers began to turn to film-based night vision devi...
