Abstract

PURPOSE: A PDP(plasma display panel) is provided to be useful for a wall-mounted TV or desktop monitor through integration of magnetic material as the integrated magnetic material obtains high brightness and efficiency. CONSTITUTION: A magnetic material(9) is formed on a rear glass(2) of a PDP. The magnetic material decreases voltage and power of plasma as well as prevents the voltage particles from being removed from a sidewall(6). Thereby, the magnetic material obtains a high-brightness device. The plasma is limited within a specific space through the magnetic material. To increase plasma density, magnetic field is applied to plasma discharging. Therefore, the power efficiency is increased and the high-brightness device is obtained.

Description

Magnetic display integrated plasma display panel {Magnetic materials integrated on plasma display panel}

The present invention relates to a plasma display panel which is one of flat panel display elements. The device is applicable to desktop monitors, wall-mounted televisions, and the like, and has a larger area than other flat panel displays such as liquid crystals and field emission displays. However, there are still many problems to be solved in order to use them as digital televisions and professional flat panel monitors that require high definition and high quality. The technical problems are high drive voltage, low power efficiency and low brightness.

In order to solve this problem, the present invention is characterized by a technique in which a magnetic material is integrated into a plasma display panel.

The present invention is to integrate the magnetic material in the panel in order to solve the problems of the conventional plasma display panel as described above, the arrangement of the magnetic material and the method of applying the magnetic material is the core of the technology. Of course, the placement method may vary depending on the structure and driving method of the plasma display panel, and it is necessary to control parameters such as magnetic material placement, application method, and magnetic field strength suitable for each device.

1 is a structural diagram of a conventional AC-driven plasma display. The display using the plasma includes a plasma display panel and a plasma addressing liquid crystal device. Plasma display panels also have a direct current drive method and direct current drive method. The AC drive system is further classified into a surface discharge system and an orientation discharge system. Usually composed of two glasses, the device creates a constant microscopic space between the two glass plates and fills it with the gas required for discharge. Two or more electrodes are arranged for discharge. Between pixels and subpixels, walls called barrier ribs are fabricated to reduce optical interference.

2 is a diagram illustrating a case where a magnetic material is disposed on the windshield of the plasma display panel. The method of applying the magnetic material is a method such as vapor deposition, screen printing and plating, but may be selected depending on the nature of the product. Although less accurate, the most advantageous method in terms of manufacturing cost is screen printing. The color of the magnetic material is advantageous to use black because the arranged magnetic material disposed on the windshield may function as a black matrix. In other words, the material can combine magnetic and black matrix functions.

3 illustrates a case where a magnetic material is disposed on the rear glass of the plasma display panel.

The magnetic material lowers the generated voltage and power of the plasma, and also serves to prevent the generated charged particles from disappearing in the partition wall, thereby obtaining a high brightness device. This is because the magnetic body can be used to limit the plasma to a certain space. When the magnetic field is used for the plasma discharge, the plasma density can be increased, the power efficiency can be increased, and the device with high brightness can be made.

Fig. 5 shows a case of the plasma display panel in the case where the magnetic material is disposed at the partition wall position. That is, it refers to a structure in which a partition wall is formed of a magnetic material. Since the bulkhead is usually an insulator, a magnetic material is mixed with the insulator.

The present invention is characterized by integrating a magnetic material to improve the characteristics of a plasma display panel suitable for wall-mounted televisions and desktop monitors. The integrated magnetic material enables high brightness and high efficiency devices according to the magnetic field distribution, which is advantageous over liquid crystal or field emission display technology to secure the market of plasma display panels.
