Abstract: A display panel and manufacturing methods thereof are provided. In one example, the display panel includes a flexible substrate having a display area and a non-display area, a dam structure located in the non-display area and disposed around the display area, one or more grooves disposed on the non-display area between the display area and the dam structure, and an organic encapsulation layer. In some examples, the organic encapsulation layer covers each of the display area, at least a portion of the non-display area, and the one or more grooves. Accordingly, a display device comprising the display panel is also provided. Thus, a flatness of the organic encapsulation layer may be improved and peeling may be reduced between the organic encapsulation layer and a substrate on which the organic encapsulation layer is disposed, thereby improving an overall quality of the finished display panel.

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.
