Abstract
An electronic device has a light emitting unit driving circuit. The driving circuit has a first driving transistor, a second driving transistor, and a light emitting unit. The first driving transistor has a first channel width and a first channel length and is used to provide a first current. The second driving transistor has a second channel width and a second channel length and is used to provide a second current. The light emitting unit is coupled to the first driving transistor and the second driving transistor for receiving at least one of the first current and the second current to emit light. A ratio of the first channel width to the first channel length is greater than a ratio of the second channel width to the second channel length.
