Drive method of light-emitting display panel and organic EL display device |
摘要 |
In a drive method of a light-emitting display panel capable of emitting light in low luminance, the parasitic capacitances of the light-emitting elements disposed in the light-emitting display panel are precharged making use of a reverse bias voltage before they are lit. In this case, a reverse bias voltage created by a reverse bias voltage creation circuit or a peak current being precharged is controlled by selectively grounding control terminals based on dimmer control. In particular, when the light-emitting elements are emitted in low luminance, the reverse bias voltage is output in a low level, thereby the light-emitting elements are prevented from being precharged with an excessive voltage. The above arrangement can realize light emission control in low luminance.
