  • Patent number: 6225029
    Abstract: An electronic array of data elements, in particular, a flat display device preferably of the PALC type in which the plasma channels are defined by walls of an organic material, preferably a polyimide material. A protective layer is provided over the polyimide walls to prevent deterioration. Spaced electrode portions are preferably provided on facing surfaces of the walls. The preferred method is to lay down a thick layer of polyimide material and a thin resist over the polyimide layer, pattern the resist, and then use the resist to pattern the polyimide layer in the shape of the desired walls. The walls are then covered with a thin dielectric sheet-like member to form the plasma channels.

  • Patent number: 5914562
    Abstract: A process for fabricating the channel substrate of a plasma-addressed electro-optic display device comprising a layer of electro-optic material, data electrodes coupled to the electro-optic layer and adapted to receive data voltages for activating portions of the electro-optic layer, and a plurality of plasma channels extending generally transverse to the data electrodes for selectively switching on said electro-optic portions and closed off by a thin dielectric sheet, typically a thin glass sheet. The channel substrate is fabricated using anodic bonding to attach the thin glass sheet to an etched or walled preferably glass substrate containing the channels. This reduces stresses in the thin glass sheet. Reduced stress allows post processing of the thin sheet, particularly further etching to reduce its thickness.
