Abstract
We are currently in the process of developing Super-Hi-Vision (SHV) system with 4320 scanning lines. In order to reproduce the image obtained on SHV on plasma display panel (PDP), the frequency of address drive circuit must be increased. This is because the address discharge period for 4320 scanning lines is so long that the desired frame rate and brightness cannot be secured for PDP. However, an increase in the frequency of the address drive circuit can result in unstable discharge and image degradation. Hence, we propose a method for simultaneous scanning of multiple lines to shorten the address discharge period and also perform a subjective assessment test to evaluate the quality of the image obtained with this method. The test results reveal a significant degradation in image quality when this method is applied to subfields with a large luminescence weight. We also confirm that it is advantageous to use the minimum error method to choose the display data.
