Abstract
A driving circuit, a driving method and a display apparatus are provided. The driving method is provided for driving a light-emitting unit including a first light-emitting element series and a second light-emitting element series connected in parallel and connected to a processing unit and a driving unit of a driving circuit. The processing unit detects a first voltage value and a second voltage value. The driving unit detects and transmits a first current value and a second current value to the processing unit. The processing unit determines and compares a first power value and a second power value. When the first and second power values are different, the processing unit controls the driving unit to adjust a driving current setting of the light-emitting element series until the first and second power values are equal. The invention ensures luminance consistency of different light-emitting element series and the luminance uniformity of display apparatus.
