By a News Reporter-Staff News Editor at Information Technology Newsweekly -- Current study results on Information Technology have been published. According to news reporting out of Tokyo, Japan, by VerticalNews editors, research stated, "Although the priming effect shortens address period and reduces address voltage, it is difficult to use the priming effect for the conventional write addressing method because the ramp reset pulses provide little priming effect. An extremely weak discharge for priming has been incorporated with write addressing method."
Our news journalists obtained a quote from the research from the University of Electro-Communications, "The extremely weak discharge is generated by priming pulse applied just prior to the scan pulse. In the 4-in-diagonal test panel containing Ne+10%Xe mixture gas, infrared emission intensity of the discharge is 900 times smaller than that of sustain discharge. Therefore, there is no degradation of dark room contrast ratio. Because the priming discharge generates a very small amount of charges, there is little reduction in the amount of wall charge accumulated during reset period. Namely, increase in address voltage can be avoided. Although the discharge intensity is extremely low, it provides sufficient priming particles for high-speed and low-voltage addressing. When priming pulse voltage is 70V and width is 10 mu s, the address discharge delay is reduced to less than half."
According to the news editors, the research concluded: "When the scan voltage margin is 10V, the data voltage is reduced to 17V, which is 20V lower than that of conventional method."
