Abstract: The present PDP includes a rear plate, a plurality of barrier ribs on the rear plate, and a front plate in parallel with the rear plate. The front plate includes a transparent dielectric layer, a plurality of joint notches on the transparent dielectric layer, and a protective layer on the transparent dielectric layer that covers the joint notches. The position of each of the joint notches is aligned with the position of one corresponding barrier rib, and each joint notch has a filler to affix within the joint notch corresponding the barrier rib. When the front plate is mounted onto the rear plate, the top of each of the barrier ribs of the rear plate is pushed through the protective layer and is embedded in the corresponding joint notch of the front plate. The filler within each of the joint notches fills the gap between the top of the barrier rib embedded in the joint notch and the joint notch so that the front plate is tightly fixed to the rear plate.

Abstract: A method of forming barrier ribs used in plasma display panels (PDP) is provided. The barrier ribs are formed on a substrate, and the substrate includes a dielectric layer and a rib material layer formed on the dielectric layer. First, a first bottom pattern layer, a second bottom pattern layer and a third bottom pattern layer are formed on the rib material layer. These bottom pattern layers have the same width and are spaced apart to each other with the same distance. Second, a first middle pattern layer, a second middle pattern layer, and a third middle pattern layer are respectively formed above the first bottom pattern layer, the second bottom pattern layer, and the third bottom pattern layer.

Abstract: A method and means for correcting the &ggr; - curve of an LCD by calculating an inverse &ggr; - curve from the &ggr; - curve of the LCD measured by the manufacturer and producing a straight line V-T plot from the combination, a set of corrected voltages selected from the inverse &ggr; - curve is provided for the different positions or viewing angles of the display, thus improving the &ggr; - curve correction efficiency at different viewing angles of the LCD. In one embodiment, a timing control ASIC, that produces the horizontal scan and vertical scan signals of the display, is used to time the outputting of sets of &ggr; - curve correction voltage signals stored in high speed memories for application, after digital to analog conversion, to the horizontal scan lines of the LCD to be corrected.
