20110050095 | Plasma Display Panel Characterized by High Efficiency - A plasma display panel (PDP) comprises: a front substrate and a rear substrate which face each other; and a barrier wall which is interposed between the front substrate and the rear substrate, which includes base portions arranged on either side of a main discharge space, and protruding portions protruding on the base portions, respectively, and which defines stepped spaces on either side of the main discharge space. The stepped spaces are formed according to stepped surfaces formed by the base portions and the protruding portions. The PDP further comprises a pair of a scan electrode and a sustain electrode which generate a mutual discharge through the main discharge space. A channel space is defined by outer walls of the protruding portions on either side of the main discharge space, and an external light absorbing layer covers the channel space. | 03-03-2011 |
20110101849 | PLASMA DISPLAY PANEL - A plasma display panel (PDP) includes: a front substrate facing a rear substrate; first and second discharge enhancement layers disposed between the front and rear substrates and arranged on both sides of a main discharge space; first and second barrier ribs respectively formed on the first and second discharge enhancement layers and defining first and second asymmetric stepped spaces along with the first and second discharge enhancement layers; a scan electrode and a common electrode inducing a mutual discharge in the main discharge space; an address electrode generating an address discharge along with the scan electrode and extending in a direction to intersect the scan electrode; a phosphor layer formed in at least the main discharge space; and a discharge gas filled in the main discharge space and the first and second stepped spaces. Accordingly, the PDP having high efficiency may operate with low power and obtain high luminous brightness. | 05-05-2011 |
