  • Publication number: 20030020404
    Abstract: A method of fabricating a plasma display panel and a front plate of the plasma display panel are disclosed. The first step of the method is to provide a front glass substrate having a pixel area and a bonding area. Next, an electrode, which has a pixel electrode positioned at the pixel area and a bonding electrode positioned at the bonding area, is formed on the front substrate. Then, a dielectric layer is formed over the pixel area and the bonding area to cover the pixel electrode and the bonding electrode, respectively. Thereafter, a rear plate is sealed to the front substrate by a sealing material so that the rear plate covers the pixel area without covering the bonding area. Then, the dielectric layer formed on the bonding area is removed to expose the bonding electrode.

Generally speaking, one frame comprises several sub-frames, each of which is displayed by one reset operation, one scan operation and a sustain operation in this driving method, the screen of the plasma display is first divided into a plurality of sub-regions. Then the controller sequentially performs the reset operation, the scanning operation and the sustain operation on these sub-regions. In the driving process, the sustain operation on one of the sub-regions is synchronized with the scan operation of another one of the sub-regions that is subsequently processed, thereby increasing the period of the sustain operation. In addition, the reset operation on one of the sub-regions does not overlap the scan operations and the sustain operations on others sub-regions for preventing signal interference.

  • Patent number: 6376813
    Abstract: A plasma display device is disclosed. The plasma display device includes a plasma display panel having a display area and a non-display area, driving circuits, comparator control circuits, and heating elements mounted on the non-display area of the plasma display panel. The non-display area surrounds the display area. A part of the driving circuit and a corresponding heating element may be a Wheatstone bridge circuit. Each comparator control circuit is coupled to the Wheatstone bridge circuit so as to control the heating element. When a portion of the display area is lit, a heating element located on the adjacent non-display area is then activated through the current balance of the Wheatstone bridge circuit and under the control of the driving circuit and the comparator control circuit. Thus, the temperature difference between the display area and the non-display area is reduced.

  • Publication number: 20020036602
    Abstract: A PDP driving method, at the first timing point of a reset period, a global voltage difference is applied between the sustaining electrodes and the scanning electrodes, wherein the gaseous discharge occurs only in the non-display areas, called the dark areas. Because the discharge during reset period does not occur in the display areas, the picture quality is assured from avoiding the emission of over-brightness in the reset period which enables the sequential gaseous discharge operations to proceed with smaller driving voltage.
