Problems solved by technology

More specifically, if each pair of electrodes 12 and 14 on the front substrate deviates from the central position of the light-emitting unit on the rear substrate, the plasma excitation efficiency of the inert gas in the light-emitting space will be reduced, resulting in reduced luminous efficiency and uneven colors. Problems that seriously affect the quality of plasma displays

Embodiment Construction

[0020] The alignment pattern of the present invention is further described in detail in conjunction with the accompanying drawings:

[0021] The following uses FIG. 2A to illustrate the alignment pattern relationship of the front and rear substrate structures of a plasma display panel according to an embodiment of the present invention. The rear substrate 100 and the front substrate 120 stacked on each other in FIG. 2A are divided into display areas 200 , 220 and non-display areas 300 , 320 respectively. The display area 200 on the rear substrate 100 is divided into a plurality of consecutive hexagonal honeycomb patterns 202 by barrier ribs (ribs), and red, blue and green phosphors (not shown) are coated in each hexagon. ) as the luminescent space.

[0022] It should be noted here that the hexagonal barrier walls referred to in the present invention can be honeycomb regular hexagons, or slightly flattened honeycomb hexagons as shown in FIG. 2A . The hexagon itself can be a f...

Abstract

An alignment configuration for the bonding of front and rear panels for the plasma display front panel, wherein the front panel and the rear panel are provided with a first pattern and a second pattern, the second pattern on the rear panel can be made through the wall blocking process for the rear panel, a honeycomb hexagonal pattern same as the display area luminescent unit can be formed on the non-displaying area, while the first pattern is formed on the corresponding position of the front panel through the opaque material manufacturing technique in the front panel production, such as a bus electrode manufacturing technique or a black matrix manufacturing technique, the first pattern comprises at least a line segment parallel to at least one side of the honeycomb hexagonal pattern on the rear panel at a predetermined distance.

Description

technical field [0001] The present invention relates to a plasma display panel (Plasma Display Panel, PDP for short), in particular to the design of an alignment mark when the front and rear panels of the plasma display panel are sealed. Background technique [0002] Flat panel displays are currently the mainstream of displays, and one of the large-size mainstreams is a plasma display (Plasma Display Panel Device, PDP for short). The color rendering principle of the plasma display mainly generates gas plasma to emit ultraviolet rays, and the ultraviolet rays then excite the red (R), blue (B) and green (G) three primary color fluorescent substances in the light-emitting unit, and the superposition of the three primary color lights Visible light mixed to produce various colors. [0003] The manufacture of plasma display panels can be divided into three major manufacturing processes: [0004] (1). The front-end manufacturing process of the front substrate: generally includes ...
