发明名称 VOLTAGE GENERATOR, DRIVING METHOD FOR THE VOLTAGE GENERATOR AND ORGANIC LIGHT EMITTING DISPLAY DEVICE USING THE SAME
摘要 A voltage generator includes a DC/DC converter and first to third transistors. The DC/DC converter outputs a first voltage during a first period of a frame period and does not output the first voltage during other periods of the frame. The first transistor is coupled between the DC/DC converter and an output terminal, and is to be turned on during the first period. The second transistor is coupled between the output terminal and a third voltage source that supplies a third voltage lower than the first voltage, and is to be turned on during a second period of the frame period. The third transistor is coupled between the output terminal and a second voltage source that supplies a second voltage identical to or lower than the first voltage, and is to be turned on during a third period of the frame period.
