Abstract: A transflective and non-rectangular display panel and a display device are provided. The non-rectangular display panel includes a display region, a non-display region surrounding the display region, multiple pixels including multiple sub pixels, and a light shielding layer. There is a first boundary between the display region and the non-display region, and a region surrounded by the first boundary and the display region is non-rectangular. Each of the multiple pixels includes at least three of the multiple sub pixels. An open region of each of the multiple sub pixels has a transmissive region and a reflective region. The multiple pixels include normal pixels in the display region and abnormal pixels passed through by the first boundary. In each of the abnormal pixels, each of the transmissive region and the reflective region is partially blocked by the light shielding layer and partially emits light therefrom.

Abstract: A driving circuit includes a first signal-input terminal, a second signal-input terminal, a third signal-input terminal, a fourth signal-input terminal, a signal-output terminal, and a voltage-boosting unit including a first module, a second module, a third module, and a first capacitor. The first module transmits the signal at the third signal-input terminal to a first terminal of the first capacitor during a first time period, and blocks signal transmission during a second time period. During the first time period and the second time period, the second module transmits the signal at the third signal-input terminal to the third module to allow the signal at the fourth signal-input terminal to be transmitted to a second terminal of the first capacitor. During a third time period, the second module and the third module both block signal transmission. The first terminal of the first capacitor is connected to the signal-output terminal for output.
