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

Embodiment Construction

[0038] figure 1 The basic structure of a liquid metal plasma color display device is described.

[0039] Such as figure 1 As shown, the liquid metal-based plasma light-emitting unit 1 composed of room temperature liquid metal electrodes, plasma dielectric materials, and fluorescent materials is attached to the substrate and packaging material 3, and displays color graphics under the control of the electrode drive circuit 2. The electrodes The driving circuit 2 can be packaged on the substrate and the packaging material 3, or can be located outside it independently. At the same time, the liquid metal-based plasma light emitting unit 1 and the plasma electrode driving circuit can form a display array, and communicate with other liquid metal via the expansion interface 4. The metal plasma display devices are connected to realize display splicing.

[0040] figure 2 The light-emitting unit structure of a liquid metal plasma color display device is described.

[0041] Such as ...

Abstract

The invention relates to a liquid metal plasma color display device and a preparation method thereof. The device includes a substrate and a packaging material, a liquid metal-based plasma light-emitting unit attached to the substrate and the packaging material, and is packaged on the substrate and the packaging material or independently The plasma electrode driving circuit on the outside of the substrate and the packaging material, the liquid metal-based plasma light-emitting unit and the plasma electrode driving circuit form a display array to display the required two-dimensional image, and communicate with other liquid metal through an extended interface The plasma display devices are connected to realize display splicing; the invention also discloses a preparation method of the device; the method has the characteristics of simpler method conditions and wider application range.

Description

technical field [0001] The invention belongs to the technical field of displays, in particular to a liquid metal plasma color display device and a preparation method. Background technique [0002] From TVs 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 expressiveness have always been the direction people are chasing. 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 successively. Among them, plasma display technology relies on wide viewing angle, 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 uses rare gas to discharge ultraviolet rays under volta...
