Patent number: 6933674Abstract: A plasma display panel using carbon nanotubes is provided. In the front panel of the plasma display panel, transparent electrodes are formed as strips on the glass substrate. Bus electrodes are each formed as strips along the outer edge on the upper surface of each of the transparent electrodes and in parallel to the transparent electrodes. A dielectric layer is formed on part of the glass substrate, parts of the transparent electrodes, and the bus electrodes. Carbon nanotube strips are aligned on the dielectric layer such that the carbon nanotube strips face the transparent electrodes.

Patent number: RE39488Abstract: A plasma display panel is disclosed, which prevents luminance from being reduced, prevents error discharge from occurring due to crosstalk, and improves exhaust ability. Auxiliary barriers or projections are formed in a boundary portion between respective cells in a stripe type barrier structure. Alternatively, a predetermined groove is formed in a predetermined position of a dielectric layer in a lattice shaped barrier structure. In addition to these barriers, second barriers are formed at a greater width or at constant intervals. Thus, exhaust ability can be improved, and error discharge due to crosstalk can be prevented from occurring. Also, luminance in corner portions of the cell can be improved, and contrast can be improved even if a black matrix is not formed.Type: GrantFiled: May 28, 2003Date of Patent: February 13, 2007Assignee: LG Electronics Inc.Inventors: Hun Gun Park, Seok Cheon Ha
