STRL is developing large ultrahigh-definition plasma display panels (PDPs) to show Super Hi-Vision television programs. STRL conducted gas-discharge simulations¦1 and PDP panel simulations¦2 and used the results to create a 58-inch ultrahigh-resolution prototype with a 0.33-mm pixel pitch.
We drew up guidelines for the optimizing the gas conditions of micro cells by comprehensively evaluating the luminance efficiency, variation in brightness, and stability of displays for different amounts of xenon in the gas mixture.
The PDP prototype has 3,840 pixels in the horizontal direction and 2,160 pixels in the vertical direction and has a 0.33 mm pixel pitch.
We will proceed with the development of 100-inch class ultrahigh-definition panels. We will also develop high-speed drive technologies and find ways to lower the power consumption of such displays.
This research is jointly carried out with Panasonic.
