Abstract:
A method of maintaining/driving the discharge of an AC discharge display in which at least one of a pair of discharge electrodes is covered with a dielectric layer. A pulse Vy is a narrow width pulse whose pulse width is shorter than a period for which the priming effect of generated charged particles or quasi-stable atoms persists in a discharge space. A pulse Vx is a wide width pulse which is generated before the priming effect produced by the pulse Vy disappears and at about the time when the pulse Vy is generated and has a pulse width long enough for the discharge to stop due to wall charges generated on the dielectric layer. The pulses Vx and Vy are continuously applied between the pair of electrodes to generate a sustained discharge and the influence of the collision of ions against the discharge electrodes and the phosphor is reduced.
Abstract:
The present invention provides an AC plasma display device using metal nanostructures, including: a front panel and a rear panel which are disposed in parallel to each other and at least one of which is provided with electrodes for gas discharge; an electrode layer, a front dielectric layer and a protective film which are sequentially formed on a side of the front panel which faces the rear panel; a phosphor layer which is formed on the rear panel and which is excited and simultaneously radiated by gas discharge occurring in the electrodes; and metal nanostructures included in the protective film and the phosphor layer, and provides a method of manufacturing the same. The AC plasma display device can improve a secondary electron emission coefficient and photoluminescent intensity using surface plasmon excitation because it is provided with a protective film including metal nanostructures.
Abstract:
The present invention relates to a plasma display panel and more particularly to a method of fabricating plasma display panels using a laser process. The method of fabricating a plasma display panel includes forming a first dielectric layer (22) on a substrate, forming a second dielectric layer (23) on the first dielectric layer (22), and forming at least one capillary in the second dielectric layer (23) and a protection layer on a portion of the second dielectric layer where the capillary is formed.
Abstract:
A highly reliable plane display panel which has a large operating margin for making displaying operations and can stably display high-quality pictures, a method for manufacturing the panel, a controller for controlling the panel, and a method for driving the panel. The plane display panel is composed of a front glass substrate (1) provided with common electrodes and individual electrodes (3, 3a and 3b) which can be driven individually at every display cell, and a back glass substrate (10) having recessed sections which become discharging spaces. At the time of driving the plane display panel, the polarity of the wall charges accumulated on a dielectric layer (5) during displaying operations is inverted by applying voltage pulses to the individual electrodes (3) separately from the displaying operations. Thereafter, the electric field of the wall charges having the inverted polarity is added to the driving voltage, so that discharge can surely take place by applying voltage pulses for display to the electrodes (3).
