Embodiment Construction

[0045] The present invention will be further described below in conjunction with accompanying drawing:

[0046] Such as figure 2 , image 3 As shown, the rear plate is composed of a rear substrate 21, an address electrode 22, a white medium 23, a barrier strip 24, a fluorescent powder 25 and a mixed gas 26, wherein the address electrode 22 is printed on the rear substrate 21, and the address electrode 22 is printed on the rear substrate 21. Print a layer of white medium 23 on the top of the white medium 23, make barrier strips 24 by sandblasting on the surface of the white medium 23, and print three primary color phosphors 25 in the corresponding barrier strips 24; 30. Composed of BUS electrodes 29, transparent medium 28, magnesium oxide cathode film layer 27, and black barrier strips 32, wherein the T-shaped scan-sustain electrode pair 30 is etched on the front substrate 31, and printed on the T-shaped scan-sustain electrode pair 30 BUS electrode 29, print transparent medi...

Abstract

The present invention provides a new three-electrode surface discharge color plasma display screen unit structure so as to implement high-precision barrier pattern generation, reduce wall load of discharge unit, reduce power consumption, make discharge easily ignite and raise addressing speed, reduce visual effect of space bar between mixed colors of three-primary colors and implemenet lifelike color. The surface discharge color plasma display screen unit structure includes front plate and back plate, and the front plate is formed from front base plate, T-type scanning-holding electrode pair, BUS electrode, transparent medium and magnesium oxide cathode membrane layer, and the back plate is formed from back base plate, addressing electrode, white medium, barrier bar, fluorescence powder and charged mixed gas. A black barrier bar is set on the transparent medium surface of front plate, and the scanning-holding electrode pair is made into the T-type.

Description

technical field [0001] The invention relates to a discharge unit structure of a color plasma display screen, belonging to the technical field of flat panel display. Background technique [0002] At present, the mainstream technology of color plasma display (Plasma Display Panel, referred to as PDP) is the three-electrode surface discharge AC-PDP technology, and its structure is as follows figure 1 shown. It consists of two front and rear glass substrates sealed together. The rear board is composed of rear substrate 1, site selection electrode 2, white medium 3, barrier strip 4, and phosphor powder 5; the front board is composed of front substrate 11, scan-sustain electrode pair 10, BUS electrode 9, transparent medium 8, and magnesium oxide cathode Layer 7, filled with gas 6 composition; [0003] The advantages of this structured PDP are: [0004] 1. Typical active light-emitting display, with clear images and strong anti-interference ability; [0005] 2. The inherent di...
