Abstract:
A plasma display panel including a gas adsorption member is disclosed. An effort of gas adsorption is obtained sufficiently, and the presence of the gas adsorption member avoids problems at an exhausting operation in exhaust-baking step. The plasma display panel includes a pair of plates opposed to each other with an enclosed discharge space in between. The pair of plates refer to a front plate and a back plate, and at least one of the plates has a communication hole, around which the gas adsorption member having a hole is disposed.
Abstract:
A plasma display panel with uniform discharge characteristics. The plasma display panel comprises a buffer layer located between display regions and exhaust holes to force impurities produced during an exhausting process to accumulate between the buffer layer and sealing layer, and be successively adsorbed by a getter layer. As a result, unusual discharge characteristics and nonuniform definitions induced by impurities can be prevented.
Abstract:
A plasma display panel has a front substrate including a plurality of display electrode pairs, a dielectric layer, and a protective layer, and a rear substrate including a plurality of data electrodes, a barrier rib, and a phosphor layer. The front substrate and rear substrate are faced to each other so that the display electrode pairs and the data electrodes intersect, and a hydrogen-absorbing material containing palladium inside is disposed.
Abstract:
A plasma display panel for improving characteristics such as a decrease in discharge voltage, a stable discharge, an increase in luminance, an increase in efficiency, and an elongation in lifetime. During or before the sealing step of sealing the periphery of a board, a phosphor layer adsorbs an impurity gas other than an inert gas. Upon panel lighting, the impurity gas is released into a discharge gas to dope the discharge gas with impurities with a high controllability. This process improves characteristics such as a decrease in discharge voltage, an increase in luminance, an increase in efficiency, and an elongation in lifetime.
Abstract:
A plasma display panel capable of realizing improvement in the characteristics thereof, such as lower discharge voltage, more stable discharge, higher luminance, higher efficiency, and longer life. During a step of sealing the periphery of substrates or before this sealing step, impurity gas other then inert gas is adsorbed by phosphor layers. The impurity gas is released into discharge gas and the impurity is added to the discharge gas in a controlled manner while the panel is lit. This method can realize improvement in characteristics, such as lower discharge voltage, higher luminance, higher efficiency, and longer life.
Abstract:
The invention applies to plasma display panels consisting of two facing plates enclosing a discharge space and comprising an array of discharge cells (X 1 , X 2 , ..., X 5 , etc.). A display panel according to the invention has at least one porous layer which contains less than 10% of a hardening agent. The porous layer is either a barrier layer or a gettering layer.
Abstract:
A getter system is disclosed for plasma flat panels used as screens. By using the getter system of the invention a reduction of the production time is obtained, as well as a better starting quality and the keeping of the starting functional characteristics of these panels.
