Problems solved by technology

Moreover, the vacuum ultraviolet rays generated by the gas discharge will not excite the entire thick phosphor layer formed in a given discharge chamber, but only excite the outermost one or two layers of phosphors, thus reducing the luminous efficiency.

Embodiment approach

[0042] According to one embodiment, the porous film 21a is formed over the entire area of ​​the dielectric layer 21 based on the X-Y plane direction. According to another embodiment, the porous film 21a is formed only on the portion of the dielectric layer 21 facing the phosphor layers 9R, 9G, 9B excited by vacuum ultraviolet rays.

[0043] According to another embodiment, the porous film 21a is formed over the entire area of ​​the dielectric layer 21 based on the Z-axis direction. According to one embodiment, the porous membrane 21a is formed of a single-layer or double-layer structure. According to one embodiment, the thickness of the porous membrane 21a is about 1 to 2 times larger than the diameter of the phosphor particles, or about the smallest diameter of the void. For example, if the diameter of the phosphor particles is about 3 μm, then the corresponding voids of the porous membrane 21 a may be correspondingly formed with a diameter of about 2 μm to about 4 μm.

Abstract

Disclosed is a plasma display panel where the shape of the phosphor layer within the discharge cell is optimized to enhance the discharge stability and the luminescence efficiency. In one embodiment, the plasma display panel includes a first substrate and a second substrate facing each other, display electrodes formed on the first substrate, address electrodes formed corresponding to the display electrodes, barrier ribs arranged between the first substrate and the second substrate such that discharge cells are formed at the locations where the display electrodes and the address electrodes correspond to each other, phosphor layers formed within the discharge cells, and a porous dielectric layer formed between the phosphor layers and the second substrate.

Description

technical field [0001] The present invention relates to a plasma display panel (hereinafter abbreviated as "PDP") having improved discharge stability and luminous efficiency when displaying images. Background technique [0002] In general, a PDP is a display that displays images using red, green, and blue (R, G, B) visible rays. Visible light is generated by exciting phosphors using vacuum ultraviolet rays. Ultraviolet rays are radiated from the plasma obtained by the gas discharge. PDP can provide screens with a size of 60 inches or larger, and the thickness is only 10cm or smaller. PDPs are self-illuminating displays like CRTs, without distortion due to color representation or viewing angles. In addition, compared with LCD, the processing steps of PDP are simple, the manufacturing cost is low, and the productivity is high, so it is attracting attention as a flat panel display for TV and industrial use. [0003] In an AC PDP (Alternating Current Type PDP), address elect...
