Embodiment 1

[0022] The temperature of the preparation environment of the pixelated liquid crystal array of the present invention must be strictly controlled below 20°C to ensure the activity of different types of liquid crystals after compounding. figure 1 The substrate shown in is ITO conductive glass, which is cut into small pieces of 1cm×1cm. The size of the selected silicone rubber heating plate is 1cm×1cm. The surface is brushed with hydrogen peroxide solution with a mass concentration of 10%. After drying at room temperature, brush again, and repeat 6 times. The surface is fully hydroxylated, dried at room temperature and coated with a black heat-resistant primer for later use. Configure compound liquid crystal ink, the mass ratio of A-type liquid crystal to B-type liquid crystal is 3:2, apply it on the surface of the pretreated silicone rubber heating plate, and apply a sealing agent on the surface after drying. Epoxy resin is used to seal the substrate and the heating plate coated...

Abstract

The invention discloses a pixelated thermochromic liquid crystal array system for light stealth, which comprises: a thermochromic liquid crystal color developing array, wherein the array is provided with a color developing element, and the color developing element is composed of a substrate layer, an electric heating layer, a color changing layer and a packaging layer; an image sensor which is used for sampling surrounding environment images; and a control unit which is used for adjusting the electric heating temperature of the electric heating layer in each color developing element according to the surrounding environment image from the image sensor so as to change the color of the color changing layer in each color developing element and achieve the purpose that the thermochromic liquid crystal color developing array adapts to the surrounding environment image. The system has the beneficial effects that the color of the device can be adaptively adjusted in time according to environmental changes, the dynamic stealth effect is achieved by reducing the color contrast of the device and the surrounding environment, the stealth performance of military equipment in the complex and changeable environment is guaranteed, and the maneuverability and combat performance of weaponry are improved.

Description

technical field [0001] The invention relates to a pixelated warm-color liquid crystal array system for light concealment. Background technique [0002] With the development of military technology, the ability of visible light imaging guidance system to find, track and intercept targets is getting stronger and stronger, and the threats faced by aircraft, tanks and other weapon systems are becoming more and more serious. Therefore, visible light camouflage and stealth will become one of the main directions for the development of military camouflage and stealth technology in the future. In recent years, researchers have proposed more and more visible light camouflage and stealth methods, and the use of intelligent color-changing materials to prepare adaptive color-changing arrays is one of the effective means to prepare high-performance visible light stealth structures. At present, the vast majority of optical stealth technologies on the market are realized through camouflage ...
