DRIVE CIRCUIT, DISPLAY UNIT, AND ELECTRONIC APPARATUS

摘要

A display unit includes: a display panel; and a drive circuit. The display panel includes pixels arranged in a matrix, signal lines configured to supply a data pulse to the respective pixels, scan lines configured to supply a selection pulse to the respective pixels, the selection pulse selecting the respective pixels for each row, and power lines configured to supply power to the respective pixels. The drive circuit includes a signal line drive circuit configured to output the data pulse to each of the signal lines, a scan line drive circuit configured to sequentially output the selection pulse to each of the scan lines, and a power circuit configured to continuously output a constant voltage to the power lines. The data pulse is formed of a signal voltage and one of a first fixed voltage and a second fixed voltage, the signal voltage based on a picture signal.
