Problems solved by technology

However, since a higher potential pulse needs to be confirmed, the power consumption of the PDP will increase, and the load on the drive part will also increase.
[0024] That is, if the discharge characteristics determined by the electrode spacing (T2) are improved, the discharge characteristics related to the discharge voltage will be weakened, and if the discharge characteristics related to the discharge voltage are improved, the discharge characteristics related to the discharge distance will be weakened.

Abstract

The invention relates to a plasma display. There are side by side aligning scanning electrodes and sustaining electrodes with certain gap, and they are mounted on the upper base plate of the plasma display; the address electrodes of the scanning electrodes and sustaining electrodes are mounted crossly on the lower base plate, the overlap parts of address electrodes and scanning electrodes are thicker than other parts. In the invention the overlap parts of address electrodes and scanning electrodes become thicker, so it can reduce the electrode gap when the plasma display keeps sparking distance to reduce the discharge voltage which is needed when the address electrodes and scanning electrodes are discharging. The invention can improve the flash-over characteristic of address period.

Description

technical field [0001] The present invention relates to the technology of the plasma display, in particular to a plasma display which can improve the discharge characteristic during the address period. Background technique [0002] Recently, the cathode ray tube (Cathode Ray Tube: CRT) or cathode ray tube, which is a mainstream product, has the disadvantages of large volume and heavy weight. Therefore, many flat panel display devices (Flat Panel Display) that can overcome the defect of the cathode line tube are being developed. [0003] These flat panel display devices include: liquid crystal display (Liquid Crystal Display: LCD), plasma display (Plasma Display Panel, hereinafter referred to as "PDP"), radiation display device (Field Emission Display: FED), electroluminescent device (Electro Luminescence: EL) Wait. [0004] Among these display devices, a PDP that can be easily fabricated into a large screen has attracted attention. PDP excites phosphors to emit light thro...
