Problems solved by technology

The use of the CEL layer does significantly reduce the addressing discharge delay of the PDP, but it does not improve the ignition voltage, luminous efficiency, contrast and other properties of the PDP. At the same time, there is still a tendency to increase the ignition voltage.

Embodiment Construction

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] In the plasma display screen and the manufacturing method thereof of the present invention, the carbon nanotube dry film vertically aligned with carbon nanotubes is attached to the inner surface of the front panel of the plasma display screen. Carbon nanotubes have a typical layered hollow structure, and there is a certain angle between the layers that make up carbon nanotubes. The tube body of carbon nanotubes is a quasi-circular tube structure, and most of them are composed of pentagonal cross-sections. The tube body is composed of hexagonal carbon ring microstructure units, and the end cap part is a polygonal structure composed of pentagonal carbon rings. Carbon nanotubes have a small radius of curvature, large aspect ratio, excellent mechanical strength and chemical stability, so it is an excellent cathode material for nea...

Abstract

The invention provides a plasma display screen and a manufacturing method thereof. The plasma display screen comprises a front panel and a rear panel, wherein the inner surface of the front panel is adhered with a carbon nano tube material, namely a vertically aligned carbon nano tube dry film. The manufacturing method of the plasma display screen provided by the invention comprises the steps of forming the front panel and the rear panel, preparing the carbon nano tube dry film, adhering the carbon nano tube dry film onto the inner surface of the front panel and sintering the carbon nano tubedry film on the front panel. According to the invention, the plasma display screen has the performances of driving voltage, luminous efficiency and contrast improved.

Description

technical field [0001] The invention relates to the field of manufacturing flat panel display devices, and more specifically, to a plasma display screen and a manufacturing method thereof. Background technique [0002] Plasma Display (PDP) is a high-performance flat-panel display device, which has obvious advantages such as self-illumination, wide viewing angle, and short response time. The current mainstream PDP display uses a three-electrode surface discharge structure. [0003] figure 1 Shows the structure of the mainstream PDP display screen, which is mainly composed of a front panel and a rear panel. [0004] In the front panel, it first includes a front glass substrate 110; then there are indium tin oxide (ITO) electrodes 120 that appear in pairs on the front glass substrate; BUS electrodes 130 are further fabricated on the ITO electrodes, and the BUS electrodes also appear in pairs, and They are respectively located on one side of the ITO electrode. Among them, the...
