Abstract:
1. A display device comprising: a plurality of pixels; and drive circuits which drive the plurality of pixels; wherein each drive circuit includes a first input/output terminal, a second input/output terminal, a scanning-direction changeover terminal, and a position designation terminal; wherein in response to a voltage applied to the position designation terminal and a scanning-direction control signal applied to the scanning-direction changeover terminal, the scanning direction is switchable between the first scanning direction which acquires a start pulse from the first input/output terminal and outputs the start pulse from the second input/output terminal and the second scanning direction which acquires the start pulse from the second input/output terminal and outputs the start pulse from the first input/output terminal; wherein the position designation terminal includes a first position designation terminal and a second position designation terminal; wherein the drive circuit, when a first voltage at a first voltage level is applied to the first position designation terminal and the second position designation terminal and a scanning direction control signal applied to the scanning-direction changeover terminal assumes a High level, acquires the start pulse from the first input/output terminal and outputs the start pulse from the second input/output terminal; and wherein the drive circuit, when the first voltage is applied to the first position designation terminal and the second position designation terminal and a scanning direction control signal applied to the scanning-direction changeover terminal assumes a Low level, acquires the start pulse from the second input/output terminal and outputs the start pulse from the first input/output terminal.
