Abstract
An AMOLED panel includes an AMOLED pixel unit, a scan driving unit and a data driving unit. The scan driving unit is coupled to the AMOLED pixel unit. The data driving unit is coupled to the AMOLED pixel unit and a voltage source and includes a switch and a DC-to-AC converter. The switch has a first terminal coupled to the AMOLED pixel unit and a second terminal coupled to the voltage source. The DC-to-AC converter has n+1 bytes, wherein n is a positive integer. The DC-to-AC converter is coupled to a control terminal of the switch and outputs a variable voltage to turn on the switch to make the switch generate a data current. The DC-to-AC converter changes a magnitude of the variable voltage to control a magnitude of the data current.
