Flat display panel having internal lower supply circuit for reducing power consumption
First Claim
1. A flat display device which employs a display high voltage for sustain discharge in addition to a logic voltage, comprising:
- a first detection unit which detects a voltage value of the display high voltage;
a second detection unit which detects an externally input signal or an existence of input display data; and
a drive control signal controller which controls a drive control signal for controlling an application of a shape of drive signal to the display device, according to the detection by the first and second detection units.

Abstract
A flat display employs at least one high voltage different from logic voltages. The display has a voltage detection unit and a drive control signal control unit. The voltage detection unit is used to detect the high voltage. The drive control signal control unit is used to control drive control signals of the flat display in accordance with the detected high voltage. This arrangement eliminates charging currents that are applied to a display panel but have nothing to do on the actual displaying of data, or reactive currents due to unnecessary switching operations, thereby reducing power consumption.
