摘要： In accordance with the invention, gradation display is performed for each picture element in capacitive display apparatuses such as EL display apparatus by means of pulse width modulation. In doing so, pulse duration of the voltage applied to one group of electrodes among the a plurality of electrodes arranged in matrix is so set as to span over two scanning periods, during which another group of electrodes which are grouped into pairs each of two adjacent lines are scanned successively. This reduces the number of drive voltage charge and discharge cycles. Consequently power consumption of the display apparatus of PWM system can be controlled to a low level.

摘要： An EL (electroluminescent) panel driving system includes a display control circuit for producing, line by line, an image data. The image data of each line is defined by a combination of a HIGH level signal representing a spot illumination of the EL panel and a LOW level signal representing a non-illumination of a spot on the EL panel. The system further includes a pre-charge circuit and a pull-up charge circuit for providing a first range voltage to the EL panel at the beginning of each line scan operation to make the EL panel ready to illuminate, and a write-in circuit and a source level switching circuit for providing a second range voltage to the EL panel to permit the spot illumination of the EL panel in accordance with the HIGH level signals contained in the image data. These four circuits are turned on by four signals. The driving system also includes a detector that detects when no HIGH level signal are present in the image data of a line, an AND gate array for cutting off the four signals from the pre-charge circuit, pull-up circuit, write-in circuit, and source circuit, the four circuits are prevented from being actuated, thereby cutting off the power normally supplied during the blank line scanning to save power.
