Problems solved by technology

At present, the main difficulty of infrared display under dark conditions is that the working task conditions are dark, which makes the conventional infrared display products lose the working effect and the identification effect is not good.
The existing solution is generally to use some passive infrared emitting materials to prepare an infrared display device so that it can be recognized. However, the main problems of the above-mentioned devices are that the display is blurred and unclear, the recognition accuracy is not high, and the service life is short.
However, how active infrared emitting materials and their corresponding devices have not been developed

Abstract

The invention discloses an infrared display device. The infrared display device includes a display film, an electrode, a packaging protection bag, and a power circuit. The display film is provided with a pattern to be displayed, and the display film is connected to the electrode, and Packaged in the packaging protection bag, the electrodes extend to the outside of the packaging protection bag and are connected to the power circuit, the base material of the display film is a non-metallic film, and the thickness of the non-metallic film is 1 ~1000μm, volume conductivity 10 2 ~10 8 S / m. The infrared display device can actively emit strong infrared rays, realize a clear and effective infrared display effect, solve the problem of infrared recognition under dark conditions, and is light in weight, good in flexibility, resistant to bending, low in power consumption, and long in service life. Can be worn on clothing, convenient and lightweight.

Description

technical field [0001] The invention relates to an infrared display device. Background technique [0002] Infrared display under the condition of no light is a subject of great significance, which can be applied to identification, night operation detection and so on. At present, the main difficulty of infrared display under dark conditions is that the working task conditions are dark, which makes conventional infrared display products lose their working effect and have poor identification effect. The existing solution is generally to use some passive infrared emitting materials to prepare an infrared display device so that it can be recognized. However, the main problems of the above-mentioned devices are that the display is blurred and unclear, the recognition accuracy is not high, and the service life is short. But how active infrared emitting materials and corresponding devices have not been developed. Contents of the invention [0003] In view of this, the present ap...
