Embodiment Construction

[0016] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] Referring to FIG. 1 , it is a schematic cross-sectional view of a PDP display barrier with a novel structure according to an embodiment of the present invention. Usually, the PDP display screen barrier is formed by connecting a plurality of barrier units, and in the present invention, each barrier unit is surrounded by arc portions of each circle between the three tangent points after three adjacent circles are tangent, Specifically, it is the arc portion between the three tangent points Q1, Q2, and Q3 that are tangent to the adjacent three red circular light-emitting units R, green circular light-emitting units G, and blue circular light-emitting units B S1, S2, S3 form. Thus, the PDP display barrier of the novel structure of the present invention has an arc-shaped curved surface structure, and the cross section of each barrier u...

Abstract

The invention discloses a PDP display panel barrier with a novel structure, which consists of arch surfaces, the section of each barrier unit forms a shape of indent circular triangle, and the barrier consists of the part among three tangency points (Q1, Q2 and Q3) after the section is tangent by three circles. The three tangent circles are circular luminous units (R), (G) and (B) of which the inner walls are coated with fluorescent powder capable of emitting red (R), green (G) and blue (B) light. The barrier makes the same plane domain obtain the largest luminous area, thereby improving the brightness of the PDP display panel; furthermore, the wall thickness of the circular luminous units (R), (G) and (B) can be reduced within appropriate range, so as to further increase the luminous area and improve the brightness. The PDP display panel barrier with the novel stricture can maximize the luminous area of the PDP display panel and further improve the brightness of the PDP display panelon the basis of eliminating light interference and improving energy conversion efficiency.

Description

technical field [0001] The invention relates to a barrier wall of a PDP display screen with a novel structure, in particular to a barrier wall of an AC gas discharge PDP (AC-PDP) display screen. Background technique [0002] PDP display (Plasma Display Panel) is a plasma display screen. The core part of PDP is composed of electrodes, barriers and phosphor light-emitting lattices. Among them, the barriers not only separate the discharge cells, but also prevent adjacent discharge cells from The role of optical crosstalk and electrical crosstalk. [0003] Barrier design is very critical in PDP structural design, which is closely related to technical parameters such as luminous brightness and contrast. The difference in the performance of PDP display screens is mainly reflected in the different structural units formed by the barriers. The traditional barrier is a strip structure, which is easy to manufacture, but with the increase in the resolution of the display screen, the hi...
