Abstract

The present invention is a flat panel display device for TVs, various monitors and outdoor large billboards by producing a plurality of fluorescent tubes on a plane by using a light emitting principle of a conventional fluorescent lamp and a local light emitting method in the horizontal and vertical directions.

The metal for the discharge electrode is deposited on the substrate of the bowel movement, and barrier ribs are installed on both sides in the direction of the discharge electrode. Inside the discharge tube formed of the diaphragm, a phosphor such as a fluorescent lamp is coated. Phosphors are also applied to the lower side of the glass plate on the front top plate and a transparent electrode film is installed in the middle. In addition, the color of the red, green, and blue color film for realizing the color on the upper electrode film of the front top plate.

In conventional long fluorescent lamps, electrodes are provided at both ends to generate discharge, but in the present invention, light is emitted by opposing discharge between electrodes in which voltage is applied to the anode between the upper and lower electrodes in the vertical direction of the long discharge space. In other words, the screen is constructed in such a way that the electrodes are installed on the front and rear surfaces so as to emit light locally in the horizontal and vertical directions. The fluorescent tube is applied to the entire fluorescent tube to emit white light and to configure a color screen through a color filter on the front.

Description

Fluorescent tube type flat panel display by plasma discharge

As a technique using plasma, flat-panel TVs using a flat panel display by plasma discharge have been developed in foreign countries and in Korea, and prototypes have already appeared. However, the device has a complicated manufacturing process and high manufacturing cost, which makes it difficult to commercialize.

Compared with the fabrication of a conventional plasma flat panel display, it is very simple and there are no technical problems associated with it.

The present invention is a flat panel display device for TVs, various monitors and outdoor large billboards by producing a plurality of fluorescent tubes on a plane by using a light emitting principle of a conventional fluorescent lamp and a local light emitting method in the horizontal and vertical directions.

The metal for the discharge electrode is deposited on the substrate of the bowel movement, and barrier ribs are installed on both sides in the direction of the discharge electrode. Inside the discharge tube formed of the diaphragm, a phosphor such as a fluorescent lamp is coated. Phosphors are also applied to the lower side of the glass plate on the front top plate and a transparent electrode film is installed in the middle. In addition, the color of the red, green, and blue color filter for realizing the color on the upper electrode film of the front top plate.

In conventional long fluorescent lamps, electrodes are provided at both ends to generate discharge, but in the present invention, a voltage is applied to the anode between the upper and lower electrodes in the vertical direction of the long discharge space so as to emit light by opposing discharge between the electrodes. In other words, the screen is constructed in such a way that the electrodes are installed on the front and rear surfaces so as to emit light locally in the horizontal and vertical directions. The fluorescent tube is applied to the entire fluorescent tube to emit white light and to configure a color screen through a color filter on the front.

1 is an exploded perspective view of the entire flat display device. The transparent color film 2 is coated on the lower end of the front plate 1 of glass or ceramic material. Transparent color film is a structural unit for realizing the colors of red, green, and blue as shown in the figure. The upper surface of the glass plate 3 under the front plate is provided with a transparent electrode and the lower surface tops the phosphor 4. The back electrode is installed on the top surface of the back plate 9, the insulating film 7 is applied thereon, and the partition 6 is installed to apply the phosphor 4 to the inner surface, and the plasma can be discharged in the gas pipe 5. The gas is injected to enclose the whole.

FIG. 2 is a diagram illustrating an electrode configuration in which plasma is formed by discharging gas in the flat panel display device configured as described above. The electrode 3 of the upper plate is made of a transparent material so as to transmit light by emitting light, and discharges the pulse type voltage having different polarities to the upper electrode and the lower electrode so as to discharge the electrode in the space between the lower electrode. Get up. When the plasma is formed in the fluorescent tube, the light from the phosphor forms a color through a color filter colored red, green, and blue on the upper surface. 3 is a cross-sectional view of a discharge cell having red, green, and blue as one pixel. 4 is a structural diagram of a discharge electrode. The upper electrode is installed so that two electrodes are paired in one plane and intersect with the lower electrode so that the intersection point represents one pixel.

The production cost is low and commercially available.

It is a flat display device intended to be used in TVs, various flat panel monitors, and outdoor large billboards by installing a plurality of fluorescent tubes on a flat surface using the principle of fluorescent lamps.
