Electrode structure of plasma display

Abstract

The invention provides an electrode structure of a plasma display. The electrode structure comprises a sustaining electrode and a scanning electrode opposite to the sustaining electrode, wherein the sustaining electrode and the scanning electrode are separated by a discharge gap; and both the sustaining electrode and the scanning electrode comprise a plurality of independent electrode units and common electrodes connected with the electrode units. Particularly, the electrode structure is a grating type electrode structure, and points are formed on the edges of the electrode units next to the discharge gap. Moreover, the grating type electrode structure can be an orthogonal type or inclined cross type grating structure.

Description

technical field [0001] The invention relates to the field of plasma displays, in particular to an electrode structure of the plasma display. Background technique [0002] A plasma display panel (PDP) is a flat panel display that emits light through gas discharge. The display principle of the plasma display is to rely on the discharge plasma generated between the electrode structures to generate ultraviolet light through discharge, and the ultraviolet light is irradiated on the three primary color phosphors to generate red, green and blue three primary color light, which is then realized through spatial and temporal modulation. Display of color images. [0003] The electrode structures of the commonly used surface discharge plasma displays mainly include the following types: [0004] 1). Strip transparent (ITO) electrode and bus (BUS) electrode structure; [0005] 2). T-shaped transparent (ITO) electrode and bus (BUS) electrode structure; [0006] 3). Multi-electrode elec...

AI Technical Summary

Problems solved by technology

[0009] The above-mentioned first two electrode structures adopt a composite electrode structure of transparent electrodes and BUS electrodes. The manufacturing process is cumbersome, the alignment accuracy is high, the process cost is high, and the capacitance between the electrodes is large.

Moreover, the above-mentioned first four electrode structures all adopt a linear electrode structure, the discharge area between the discharge electrodes is small, and the luminous brightness and luminous efficiency are low.

The cell aperture ratio of the fifth electrode structure is small, which will also lead to a decrease in luminous brightness, and the manufacturing process is troublesome, and the product quality is not easy to control

[0010] In the case of using the ITO-less grid-type electrode structure, the main problems in the electrode structure are that the ignition voltage between the discharge electrodes (including the sustain electrode and the scan electrode) is too high and the brightness of the PDP is not enough. Therefore, it is necessary to propose a A new type of electrode structure for plasma displays has solved the above problems
