Problems solved by technology

For the structure in which the pixel is composed of three primary color sub-pixels arranged in parallel, since the length of the sub-pixel along the vertical direction is three times the length of the horizontal direction, and the X electrodes and Y electrodes are arranged along the horizontal direction, the effective area of ​​the pixel The utilization rate is very low, resulting in low discharge efficiency

Abstract

The invention discloses a plasma display screen with an interdigital electrode structure, which belongs to the technical field of flat plate display. A bus electrode of an X electrode on a front plate and a bus electrode of a Y electrode are arranged horizontally; and the X electrode and the Y electrode have interdigital structures, are arranged vertically and are connected with respective bus electrode vertically and crossly. Compared with the prior art, the plasma display screen has the advantages of simple structure, high luminous efficiency and the like.

Description

technical field [0001] The invention belongs to the field of flat panel display technology, and in particular relates to a plasma display screen with an interdigitated electrode structure. Background technique [0002] Improving the luminous efficiency of plasma display screen (PDP) is the key to whether plasma TV can obtain a larger market share. The current commercially available products have reached 1.8 lumens / watt, and the overall luminous efficiency is slightly higher than that of liquid crystal displays. In today's increasingly tense energy environment, the power consumption of this kind of flat panel display is still very large. Taking a 55-inch TV as an example, to achieve the high brightness required for high-definition, the power consumption exceeds 500 watts. This indicator must be improved as soon as possible in order to be suitable for the general direction of energy conservation and environmental protection. [0003] There are many factors that affect the lu...
