Abstract
A display panel and a method for adjusting brightness thereof, and a display apparatus. The display panel includes a first and a second display area. A pixel density of the first display area is less than a pixel density of the second display area. The display panel includes a power supply unit including a power supply output terminal; first power supply lines electrically connected to sub-pixels of the first display area; second power supply lines electrically connected to sub-pixels of the second display area; and a voltage adjusting unit. First ends of the second power supply lines are electrically connected to the power supply output terminal, second ends of the second power supply lines are electrically connected to the first power supply lines via the voltage adjusting unit, and the voltage adjusting unit is configured to adjust a voltage on the first power supply lines.
