  • Publication number: 20070097053
    Abstract: In a PDP apparatus a first protrusion is formed in the column direction at a scan electrode. A second protrusion is formed in the column direction at a sustain electrode. The first and second protrusions face each other with a protrusion gap therebetween. An area of the first protrusion is greater than that of the second protrusion. A first sustain pulse is applied to the scan electrode and a second sustain pulse is applied to the sustain electrode in a sustain interval. In an exemplary embodiment a first interval during which a voltage of the first sustain pulse is less than that of the second sustain pulse is longer than a second interval during which a voltage of the first sustain pulse is greater than that of the second sustain pulse.

  • Patent number: 7161299
    Abstract: A design for a plasma display panel that both reduces the capacitance between adjacent address electrodes while improving the optical characteristics of the display. This is achieved by having a layer formed on the rear substrate over the address electrodes being made of two separately patterned substances. The two substances have different dielectric constants while different optical properties. Preferably, the visible light generated in the phosphor layer of the display is reflected off the layer formed over the rear substrate and then transmitted through the front substrate.

  • Publication number: 20060238124
    Abstract: A dielectric layer increases color temperature and contrast ratio, and prevents brightness reduction. A plasma display panel includes the dielectric layer. The dielectric layer includes a base glass and a transition metal compound. In the dielectric layer, the transmittance of visible light having a wavelength of 430 to 480 nm is greater than the transmittance of visible light having a wavelength of 530 to 560 nm or 580 to 660 nm.

  • Patent number: 7109658
    Abstract: A plasma display panel is provided. The plasma display panel includes a front substrate, an X electrode and a Y electrode alternately formed on the front substrate, a dielectric layer formed to cover the X and Y electrodes, a rear substrate installed to face the front substrate, address electrodes formed on the rear substrate and intersecting the X and Y electrodes, barrier ribs formed between the front and rear substrates, and red, green, and blue fluorescent layers applied in discharge cells defined by the barrier ribs. The dielectric layer and the barrier ribs are colored with two complementary colors that essentially filter out nearly all light. Accordingly, it is possible to reduce outdoor daylight reflection and improve image contrast by an improved design over the use of black stripes.
