Patent ID: 8063858

Claim:
A display apparatus, comprising: an active matrix display panel including light emission element driving circuits having capacitors for holding a data signal and driver transistors for driving light emission elements based on data signal voltage held by the capacitors, and a plurality of pixel units each of which has the light emission element and is arranged in matrix with lines and rows; a scanning driver for sequentially scanning each of scanning lines provided for the corresponding line of the pixel units; a data driver for supplying the data signal to the pixel units via data lines in response to scanning by the scanning driver; ramp voltage lines each of which is provided for the corresponding scanning line of the display panel and is connected to the light emission element driving circuit; a ramp voltage generating section for generating ramp voltage which varies the control electrode voltage of the driver transistor relative to the voltage of the source electrode of the driver transistor to change the light emission state of the light emission elements; and a ramp voltage driver for supplying the ramp voltage to each of the ramp voltage lines provided for the corresponding scanning line in response to the scanning of the scanning lines, wherein: each of the first terminals of the capacitors is connected to the control electrode of the driver transistor; each of second terminals of the capacitors is connected to a predetermined voltage; and the source electrode of the driver transistor is connected to the corresponding ramp voltage line provided for the corresponding scanning line of the display panel and receives the ramp voltage.
