Liquid metal plasma color display device and preparation method thereof

Abstract

The invention relates to a liquid metal plasma color display device and a preparation method thereof. The device comprises a substrate and package material, a plasma light-emitting unit based on liquid metal and a plasma electrode driving circuit, wherein the plasma light-emitting unit based on the liquid metal is attached to the substrate and package material, and the plasma electrode driving circuit is packaged to the substrate and package material or is independent of the substrate and package material. The plasma light-emitting unit based on the liquid metal and the plasma electrode driving circuit form a display array to display a needed two-dimensional image and are connected with other liquid metal plasma display devices through an expansion interface to achieve display splicing. The liquid metal plasma color display device and the preparation method thereof have the advantages that conditions of the method are simpler, and the application range is wider.

Description

Technical field [0001] The invention belongs to the technical field of displays, and particularly relates to a liquid metal plasma color display device and a preparation method. Background technique [0002] From televisions to monitors, display devices have penetrated into all aspects of people's production and life, and larger screen sizes, higher display resolutions, and richer image expression have always been people's pursuit. In the field of display technology, technologies such as cathode ray tube (CRT), liquid crystal display (LCD), and light-emitting diode (LED) have been born. Among them, plasma display technology relies on wide viewing angles, fast image response speed, no flicker, The advantages of thin thickness, light weight, large area, bright colors, vivid images, no radiation, health and environmental protection occupy a place. [0003] The traditional color plasma display technology mainly generates ultraviolet rays through the discharge of rare gases under volta...

Problems solved by technology

[0005] However, the existing plasma display technology also has certain limitations. Since the excitation electrode is a solid metal array, its processing requires complex processes such as photolithography, corrosion, and chemical vapor deposition, and the metal paste needs to go through hundreds or even Thousands of degrees of high-temperature sintering; and because the excited substance is a rare gas, the excitation voltage is high (generally, the voltage difference between the substrates is above 100V), and the cost of material acquisition and packaging is high; in addition, because electrodes, substrates, etc. It is a rigid material, so the display screens based on traditional plasma display technology are generally hard flat panels, which cannot realize curved or flexible displays
