  • Publication number: 20060043894
    Abstract: A plasma display panel design having a display area and a peripheral area surrounding the display area. Within the display area are discharge cells, and within the peripheral area are dummy cells that serve as a location where fluorescent paste is injected onto in an early stage of making the display, enabling the injection amount and injection speed from a nozzle to stabilize before the fluorescent material is deposited into the discharge cells. A surface area that the fluorescent material is deposited on in the peripheral area is increased to provide for a more rapid stabilization of the injection pressure and injection amount of the paste in the making of the display. A sufficient gap is present between a sealant and the dummy structure so that air and foreign matter can be expelled.

  • Publication number: 20060028404
    Abstract: A method of driving a plasma display panel (PDP) and an apparatus for carrying out the method. The PDP includes address electrodes with first electrodes and second electrodes intersecting the address electrodes. Gray-scale levels being represented by combinations of sub-fields, each sub-field having a reset period, an address period, and a sustain-discharge period. The different gray scales are achieved not only by modifying the voltage waveforms in the sustain-discharge period but also by modifying the voltage waveforms in the reset period, allowing for better control over gray scales and better contrast. Different sub-fields can have different voltages applied during the reset period which affects the luminance of the image displayed. A circuit for making the above voltage waveforms is also presented.

  • Publication number: 20060006802
    Abstract: A plasma display panel capable of preventing faulty discharge and non-uniform discharge by applying a uniform address voltage to all subpixels. This is done by neutralizing the negative surface potential of a zinc silicate green fluorescent material using YBO3:Tb as a positive surface potential material on the partition walls between the electrodes. Also, the thickness of this YBO3:Tb material and a lateral spacing between a scan electrode and the positive surface potential material are carefully selected to arrive at a design resulting in no faulty pixels. Grooves can also be formed in the tops of the partition walls so that the positive surface potential material filled therein does not mix with the neighboring flourescent material.

  • Publication number: 20050258751
    Abstract: A plasma display panel (PDP) designed to reduce the amount of external light that is reflected. This is accomplished by having some phosphor material on portions of the tops of the barrier ribs outside the discharge cells. Since the reflectance of the barrier rib material is higher than that of phosphor material, such a design will reduce the amount of external light reflected off the screen of a plasma display panel. By reducing external light reflection, the contrast of the image is improved. This can be achieved while still preventing crosstalk between neighboring discharge cells.
