Abstract
An OLED display assembly includes a DC-DC power source driver chip and an OLED display panel. The DC-DC power source driver chip is provided with a soft-start circuit including a first time-delay circuit, a first anti-surge circuit and a second anti-surge circuit. The first time-delay circuit is configured to disable the first anti-surge circuit and enable the second anti-surge circuit at an initialization stage, delay a voltage applied to an output end of the first time-delay circuit, and after the end of the initialization stage, enable the first anti-surge circuit and disable the second anti-surge circuit. The first anti-surge circuit is configured to control, after the end of the initialization stage, a voltage applied to the first input end of the OLED display panel. The second anti-surge circuit is configured to control, at the initialization stage, a voltage applied to the first input end of the OLED display panel.
