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 photo-converting device provided by the present invention is combined by arranging the photosensitive component and the light-emitting component side by side on the substrate, and at the same time setting the light-emitting component to include a first electrode disposed on the substrate, a light-emitting component disposed on the first electrode At least two light-emitting units and the carrier generation layer arranged between adjacent light-emitting units make the light-emitting component have a doubled light-emitting current efficiency, so that the device can obtain higher light-sensing and light-emitting efficiency, and at the same time due to the compact structure of the device , small size, and light weight, thus meeting the requirements of portable imaging of the device; and because each pixel has a simple structure and low process difficulty, each pixel is suitable for the existing printing preparation process, reducing costs, and realizing large-area printing copy.

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...
