Abstract: Response fidelity problems appear for some specific video levels at PDP borders. The reason is that some cells at the border of the PDP panel are not completely closed and pollute when switched ON neighbouring cells being OFF. Therefore, it is suggested to encode the video levels in the border area in a specific way. Especially, for critical sub-fields within the code it is forbidden to insert a binary 0 between two binary 1. Thus, the neighbourhood of critical sub-fields being ON and OFF is avoided. Preferably, the specific border coding is performed under the control of an average power management and codewords being not used are recreated by dithering.

Abstract: In a row-electrode drive circuit of a PDP display device, an N-channel MOS low-side transistor of an output section is in an ON state while a light emission of a capacitive load is sustained. Now, if power to a driver section is lost due to, for example, a disconnection of a line from an external power supply to a low-voltage power terminal, this loss of power is detected by a detection section, and a current path via a parasitic diode of a P-channel MOS transistor, which has turned off, in the driver section to the low-voltage power terminal is interrupted. As a result, the N-channel MOS low-side transistor of the output section has the charged electric charge of the capacitive load stored in a parasitic capacity between its drain and gate, so maintains the ON state.
