Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a plasma display device, and more particularly, to a high efficiency plasma display panel device and method of fabricating the same. Although the present invention is suitable for a wide scope of applications, it is particularly suitable for the plasma display panel device for reducing a turn-on voltage and significantly increasing a UV-emission without increasing a discharge operation voltage.




2. Discussion of the Related Art




Plasma display panel(PDP) devices use gas discharges to convert electric energy into light. Each pixel in a PDP device corresponds to a single gas-discharge site and the light emitted by each pixel is electronically controlled by the video signal that represents the image.




The unique advantage of plasma displays is that they combine a large screen size with a very thin display panel. Generally, PDP is the choice for large size display devices, typically larger than 40″ diagonal.




A DC operating PDP device has advantages of high controlled brightness and a fast response time. However, the structure is complicated. Further, a life time of the device is limited by current limiting resistors since the DC PDP device includes resistors. On the other hand, an AC operating PDP device has a simpler structure and higher reliability than those of the DC PDP device.




Most of the conventional AC PDP devices utilizes an AC barrier type discharge as disclosed in U.S. Pat. No. 5,674,553. As shown in

18


, address electrodes


22

29


, and phosphor layers


28


R,


28

B.




However, the conventional AC PDP device has low density plasma, resulting in a low brightness and a slow response time due to a charging time on the dielectric wall. As a result, gray scale problems occur in the display device. Further, the deposition of MgO films on the dielectric layer to enhance secondary electron emission causes high manufacturing cost and limits the life time of the device.




SUMMARY OF THE INVENTION

A capillary type PDP device of the present invention utilizes a new type of electrical discharge in gas in which high density plasma is produced. Plasma is generated in the capillary. The number and the dimension of the capillaries may be varied to optimize discharge characteristics.

a


. High density plasma in the capillary emerges from the end of the capillary into the discharge chamber, serving as an electrode for the discharge chamber. The field inside of the capillary does not collapse after forming a streamer discharge. This is due to a high electron-ion recombination at the wall requiring a large production rate on the axis (and therefore a high field) in order to sustain the current.

FIG. 19C

illustrates that a double layer of electric field exist at the interface of the capillary and the main discharge chamber. By selecting a ratio of the diameter d of the capillary to the length of the capillary L, a steady state high density plasma discharge can be sustained in the discharge chamber.

is formed between the barrier ribs

is filled with an inert gas mixture such as Xenon (Xe) to generate a UV emission. On the front substrate


30


, a first electrode


31


is formed for biasing the field to the viewing direction, thereby more effectively improving the images on the viewing panel. About −100˜250 V is applied as a biasing voltage. A dielectric layer


33


is formed on the first electrode


31


. In each pixel, at least one capillary


34


is formed in the dielectric layer


33


, so that the first electrode


31


is exposed to the discharge chamber


36


. A pair of second electrodes


32


are formed in the dielectric layer


33


in the vicinity of each capillary. A sustain voltage smaller than a discharge operation voltage is applied to the second electrodes


32


. For example, the sustain voltage is in the range of 160˜200 V and the address voltage is between 50 and 250 V. A third electrode


38


on the rear substrate


39


acts as an address electrode. An address voltage is applied only to the third electrode

as a biasing electrode. For example, a transparent dielectric layer

, such as lead oxide (PbO) glass, is formed on the first electrode


61


including the front substrate


60


. A plurality of second electrodes


62


, made of ITO, are formed in the dielectric layer


63


as sustain electrodes. A third electrode


65


, formed of silver (Ag), may be formed on each of the plurality of electrodes

illustrates a cross-sectional view of a front substrate of a PDP device according to a third embodiment of the present invention. As shown in

forms a curvature. Generally, an amount of charges is determined by the thickness of the dielectric layer on the sustain electrode. In turns, the current is limited by the amount of charges. The curvature reduces a thickness of the dielectric concentrated on the discharge surface. Thus, more uniform discharge may be generated on the surface. In addition, since the opening of the capillary may be larger than the diameter, the amount of discharge volume is maximized by diffusing the discharge from the opening. Also, performance of PDP device can be optimized by adjusting the following various parameters shown in FIG.

FIG. 14

illustrates a relationship between a discharge operation voltage and a pressure in the discharge chamber of the conventional AC barrier type PDP device (solid squares) and the capillary type PDP device of the present invention (open circles). As shown in

FIG. 14

, for the capillary type PDP device of the present invention, the discharge operation voltage of the device decreases as the pressure increases in the range of about 300 Torr and 760 Torr, while the driving voltage of the device increases as the pressure increases for the conventional the AC barrier type PDP. As a result, the capillary type PDP device of the present invention does not require a higher discharge operation voltage even if the pressure of the device is increased.





FIG. 15

is spectra illustrating relative photo-emission intensities for the conventional AC barrier type PDP (dotted line) and the capillary type PDP (solid line) of the present invention at the same driving voltage. The intensity of the capillary type PDP device of the present invention is much higher than that of the AC barrier type PDP device under the same driving voltage.





FIGS. 16 and 17

are spectra illustrating relative intensities for current and photo-emission at a fixed AC voltage for the conventional AC barrier type PDP and the capillary type PDP of the present invention, respectively. The current and photo-emission intensities of the capillary type PDP device of the present invention are much higher than those of the AC barrier type PDP device at the same AC voltage.




As discussed above, a plasma display panel device and method of fabricating the same of the present invention has the following advantages.




According to the present invention, the field in the capillary does not collapse. Thus, a high electric field discharge is maintained in the capillary. As a result, much enhanced brightness is obtained in the PDP device of the present invention. Also, the PDP device of the present invention does not require a higher driving voltage as the pressure in the discharge chamber increases up to the atmospheric pressure.




In addition, the PDP device of the present invention is capable of being operated in both an AC and DC mode and has an address voltage of 50 to 250 V, which is much smaller than that of the conventional PDP device. This is because a breakdown voltage is lowered by using a large field across the dielectric layer in the early phase of a cycle for generating electron avalanches in the capillary.




A structure of the PDP device of the present invention is simpler than that of the conventional DC PDP device since a current limiting resistor on the dielectric layer is necessary for the present invention.




Further, unlike the conventional PDP device, a response time is very short because a time for dielectric charging is eliminated from the response time.




Accordingly, the present invention has a high efficiency in generating a steady state high density UV emission.




It will be apparent to those skilled in the art that various modifications and variations can be made in a plasma display panel device and method of fabricating the same of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
