Publication number: 20030076039Abstract: To provide a display panel, such as a PDP, that can reduce noise caused by a collision sound which occurs when a front panel member and a back panel member vibrate while the display panel is being driven. Projections (21) are provided on a surface of a first panel member facing a second panel member. The first panel member and the second panel member are connected to each other by a connecting material in areas (23) where the projections intersect barrier ribs (18). In this way, noise (noise level) caused by a collision sound which occurs when the front panel member and the back panel member vibrate while the display panel is being driven can be reduced.Type: ApplicationFiled: October 11, 2002Publication date: April 24, 2003Inventors: Masafumi Ookawa, Junichi Hibino, Yoshiki Sasaki, Katuyoshi Yamashita

Patent number: 6534916Abstract: Electric discharge is caused in a concave portion (12) to generate ultraviolet light. The ultraviolet light is incident upon a fluorescent layer (14), which emits visible light. The emitted visible light is transmitted through transparent electrodes (24a, 24b) and radiated from a surface. Because spherical materials (16) are arranged on the inner surface of the concave portion (12), the surface area of the fluorescent layer (14) is enlarged, more ultraviolet light enters the fluorescent layer (14), and the conversion efficiency from ultraviolet to visible light is enhanced.Type: GrantFiled: March 4, 1999Date of Patent: March 18, 2003Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Atsushi Ito, Hironobu Arimoto, Kazuhisa Hemmi

Patent number: 6531817Abstract: An image display panel includes a number of channels extending in a first direction. First electrodes extend parallel to the channels and a pair of second electrodes extend perpendicular to the channels. An image cell is created at the position where the pair of second electrodes cross a crossing of a first electrode. An array of cylindrical lenses is arranged on the viewer's side of the panel each having a longitudinal axis substantially parallel to the second electrodes. The pitch of the lens array may be equal to the vertical pitch of the image cells, while the array is shifted with respect to the image cells in a direction substantially perpendicular to the second electrodes. Also, the pitch of the lens array may be smaller than the vertical pitch of the image cells with or without with the aforementioned shift of the lenses with respect to the image cells.Type: GrantFiled: December 22, 1999Date of Patent: March 11, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Antonius H.

Publication number: 20030038599Abstract: A plasma display panel that requires lower consumption power to drive is proved. This plasma display has a good luminance efficacy, is less tending to yellowing of glass and deterioration of phosphors, and is manufactured at a low cost. The dielectric layers and ribs of the PDP are made from a silicone resin containing polysiloxane bond. Preferably, the silicon resin should have siloxane bond joined with methyl group, ethyl group or phenyl group. It is also preferable that a sealing member is made from a silicone resin.Type: ApplicationFiled: September 19, 2002Publication date: February 27, 2003Inventors: Masaki Aoki, Taku Watanabe

Patent number: RE38357Abstract: A surface discharge type plasma display panel has a dielectric layer facing to a discharge gas space and a pair of sustaining electrodes embedded in the dielectric layer and disposed apart from each other by a discharge gap on one of the substrates spaced parallel to each other at the discharge gas space. The dielectric layer includes a pair of first thickness portions formed on far ends of the electrodes from the discharge gap respectively which are larger than a second thickness portion on facing near ends of the facing electrodes. The dielectric layer is provided with a depth from its surface to the substrate larger than that on the second thickness portion between adjacent the electrodes. This plasma display panel prevents any useless expansion of the surface discharge over the sustaining electrodes.Type: GrantFiled: July 1, 1999Date of Patent: December 23, 2003Assignee: Pioneer CorporationInventors: Kimio Amemiya, Yukio Tanaka, Hitoshi Teshirogi
