Abstract
An organic light emitting diode display device capable of achieving a considerable reduction in power consumption by generating a drive signal only for a period, in which the drive signal is actually required, is disclosed. The organic light emitting diode display device includes a DC-DC converter including a switching element to generate a drive signal by controlling an input voltage under a control of a logic, and a driver to supply, to pixels, the drive signal generated from the DC-DC converter in accordance with a timing. The logic includes an AND circuit to AND a control signal for drive signal generation and an output control signal maintained at a logic-high voltage only for a period in which the drive signal is to be supplied, and to supply a result of the ANDing operation.
