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 the photosensitive member is set as a photoconductor structure provided with a second electrode, a first electron transport layer, a light absorbing layer, and a second electron transport layer which are laminated. The photoconductor structure replacing an existing diode structure has high light detection efficiency, so that the device has higher light guiding and light emitting efficiency. Due to the compact structure, small size and light weight of the device, therequirements for portable imaging of the device are met. And because each pixel has a simple structure and low process difficulty, each pixel is suitable for the existing printing preparation process, which can realize large-area copying and reduce production cost.

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...
