5.2 Driver Circuit
5.2.1 Driver Circuit Overview
(1) WHAT IS THE DRIVER CIRCUIT
It is a circuit generating an appropriate pulse(High voltage pulse) and then driving the panel to implement
images in the external terminals(X electrode group, Y electrode group and address electrode), and this high
voltage switching pulse is generated by a combination of MOSFETs.
(2) PANEL DRIVING PRINCIPLES AND TYPES OF DISCHARGE BY DRIVE PULSE
In PDP, images are implemented by impressing voltage on the X electrode, Y electrode and address electrode,
components of each pixel on the panel, under appropriate conditions. Currently, ADS(Address & display
Separate: Driving is made by address and sustaining sections) is most widely used to generate the drive
pulse. Discharges conducted within PDP pixels using this method can largely be classified into 3 types, as
follows:
??
Address discharge: This functions to generate wall voltage within pixels to be lighted by addressing
information to them(i.e., impressing data voltage)
??
Sustaining discharge: This means a display section where only pixels with wall voltage by the address
discharge display self-sustaining discharge by the support of such wall voltage. (Optic outputs realizing
images are generated.)
??
Erasing discharge: To have address discharge occur selectively in pixels, all pixels in the panel must
have the same conditions(i.e., the same state of wall and space electric discharges). The erasing
discharge section, therefore, is important to secure the drive margin, and methods most widely used to
date include weak discharge by log pulse, self-erasing discharge by strong discharge, and wall voltage
controlling by lamp pulse.
