We arrayed leaky fused-quartz lightguides, each illuminated by GaAlAs light-emitting diodes, to make a row-addressable backlight. It was much more efficient than a dc-plasma row-backlight that we made also. Test patterns were displayed by operating the backlight with a ferroelectric liquid-crystal shutter array, and gray-scale capability was demonstrated.
This paper consists of structural reformation of the panel to solve the specific characteristics of low brightness in conventional color PDP. Installation of auxiliary electrode and then selecting pulse memory driving method is widely known as the most desirable way for PDP.^<[1.2.3]> In this experientment, unlike the existing panel structure, we've studied and surveyed the special character of installation of auxiliary electrode on top of the 1^<st> Barrier Rib. In this selection of structure, resolution is improved as cell pitch of panel is decreased, at the same time improves the brightness by the effect of memory.
We have made a numerical analysis of the micro-discharge in plasma display panel using 2-dimensional multi-fluid equations. The plasma gas is Ne + Ar 0.1% gas in a state of non-LTE glow. We obtained the distributions of the microscopic variables such as the density, temperature, velocity of ion and electron. We also found the distributions of excited species during glow and after glow. From the simulation result, the non-discharge pulse applied to the auxiliary anode affect the distribution of ion density, meta-stable density and other excited species considerably. We have also found that the optimization of the frequency and voltage of the discharge pulse could improve the efficiency of the DC memory PDP.
Impressive Hi-Vision (HDTV: High-definition TV) pictures have been reproduced on 33-inch and 40-inch color DC plasma displays. This success was due to the development of the fabrication of large-area color DC PDPs, pulse memory drive technique, and signal processing. This paper describes the fabrication process --mainly thick-film printing and phosphor deposition-- for large-area color DC PDPs, developed to make Hi-Vision flat receivers.
In this paper we present an ac plasma display adopting new structure that seperates the addressing and sustain operations to operate not only the vertical data but also the horizontal scanning with high impedance driver. In our 4-electrode type methods, the sustain electrodes and scanning electrodes are acting as capacitive coupling. The scanning driver consists of open drain and the sustain operation is made by the seperated sustain driver. We believe that the high impedance driver IC can be used as not only the vertical data driver but also the horizontal scanning driver and the whole panel can be operated by one pair of output from sustain driver.
