Plasma Display Panel Structure

Since this is a trivial issue, I did not include the contents of the text.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display panel, and more particularly, to a plasma display panel structure in which a lower electrode having a predetermined thickness is formed on an upper surface of a lower plate glass of a plasma display panel.

1 is a cross-sectional view of a conventional plasma display panel.

Referring to FIG. 1, a plasma display panel according to the related art includes an upper structure and a lower structure roll.

The upper structure is formed by forming a plurality of upper electrodes 11 having a predetermined width and height on the same surface of the upper plate glass 10 and forming a dielectric layer 12 on the upper electrode 11 by a printing technique, A protective layer (13) is formed on the dielectric layer (12) formed on the electrode (11).

The upper substructure is formed by forming a lower electrode 15 having a predetermined thickness and width on the lower plate glass 14 and preventing crosstalk between discharge cells adjacent to the lower electrode 15 A phosphor 17 is formed on the opposite surface of the barrier rib 16 and the lower electrode 915. [

In addition, an incombustible gas is sealed in a space between the upper structure and the lower structure to have a discharge area 18.

The operation of the plasma display panel according to the related art will now be described.

When a voltage is applied to the upper electrode 11 and the lower electrode 15, a discharge is generated in the discharge region 18 of the dielectric layer 12 and the surface of the protective layer 13, and an ultraviolet ray 19 is generated.

That is, an inert mixed gas, that is, helium (He), which is filled in the discharge cell at a pressure of about 400 to 500 torr as a main component, is accelerated to a negative (- A penning gas mixture containing xenon (Ne) gas, neon (Ne) gas and the like is added and the ultraviolet rays 7 of 147 nm are generated while the inert gas is excited.

The ultraviolet ray 19 collides with the phosphor 17 surrounding the lower electrode 15 and the partition wall 16 to emit light in the visible light region.

Accordingly, the phosphor 17 is excited by the ultraviolet ray 19 emitted and the color display is performed by the emitted phosphors 17.

The plasma display panel according to the related art has a problem that the lower electrode 15 formed on the lower plate glass 14 has a smaller width so that the lower panel electrode 15 is formed outside the excitation light emission of the phosphor 17 by the ultraviolet ray 19 There is a problem that the self-luminous portion to be emitted by the light-emitting diode becomes small and the luminance is lowered.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a plasma display panel in which a lower electrode is formed on a facing surface of a barrier rib and a lower glass of a plasma display panel, Thereby improving the brightness of the plasma display panel.

Referring to FIG. 2, the lower cell of the plasma display panel according to the present invention includes barrier ribs 16 having a predetermined width and height on a lower plate glass 14 and preventing electrical and optical crosstalk between adjacent pixels, A lower electrode 15 having a predetermined thickness is formed on the opposite surface of the lower plate glass 14 and the barrier rib 16 and a phosphor 17 is formed on the entire surface of the lower electrode 15.

FIG. 3 is a cross-sectional view of a plasma display panel according to another embodiment of the present invention. Referring to FIG.

Referring to FIG. 3, the plasma display panel according to the present invention has an upper structure and a lower structure.

The upper structure is formed by forming a plurality of upper electrodes 11 having a predetermined width and height on the same surface of the upper plate glass 10 and forming a dielectric layer 12 on the upper electrode 11 by a printing technique, A protective layer (13) is formed on the dielectric layer (12) formed on the electrode (11).

The lower structure has partition walls 16 having a predetermined width, height and pitch on the lower plate glass 14 to prevent electrical and optical crosstalk between adjacent pixels, and the lower plate glass 14 and the partition walls A lower electrode 15 having a predetermined thickness is formed on the opposite surface of the lower electrode 15, and a phosphor 17 is formed on the entire upper surface of the lower electrode 15.

In addition, an inert gas is sealed in a space between the upper structure and the lower structure to have a discharge region 18.

When a voltage is applied to the upper electrode 11 and the lower electrode 15, a discharge is generated in the discharge region 18 of the dielectric layer 12 and the surface of the protective layer 13, and an ultraviolet ray 19 is generated.

In other words, the electrons existing in the discharge cells are accelerated to the negative (-) side by the applied driving voltage, and the inert gas filled in the discharge cells at a pressure of about 400 to 500 torr, that is, helium as a main component, ), Neon (Ne) gas and the like, and the ultraviolet rays 7 of 147 nm are generated while the inert gas is excited.

The ultraviolet ray 19 hits the phosphor 17 on the upper surface of the lower electrode 15 and emits light.

Therefore, when a voltage is applied to the lower electrode 15, the entire self-emission is emitted.

A color display is performed by the emitted phosphors 17.

The plasma display panel according to the present invention has a bottom electrode formed with a predetermined thickness on the upper surface of the lower plate glass and the opposite surfaces of the barrier ribs,
