Title: Innovations by Chang Young Kwon in Plasma Display Technology
Introduction
Chang Young Kwon is a notable inventor based in Pohang-si, South Korea. He has made significant contributions to the field of plasma display technology, holding a total of five patents. His work focuses on improving the performance and efficiency of plasma display panels (PDPs).
Latest Patents
One of his latest patents is a method and apparatus for driving a plasma display panel. This invention provides a method for widening the driving margin and improving contrast in PDPs. The method includes a first step of forming wall charges in cells with a set-up discharge using a set-up signal in a first sub-field. It also involves erasing the wall charges with a set-down discharge using a first set-down signal to initialize the cells. The second step includes erasing the wall charges with a set-down discharge generated using a second set-down signal in a second sub-field. This innovation uniformly initializes sub-fields to enhance the driving margin and improve the contrast of PDPs.
Another significant patent by Kwon relates to a plasma display apparatus having overlapping voltages applied to sustain electrodes. This invention addresses the issue of wall charges remaining without performing an additional erasing discharge after the sustain period. By generating the set-up discharge with a small voltage during the reset period, the driving voltage margin can be obtained. This method improves the contrast due to luminous output reduction, particularly in subfields implementing low gray scales.
