Abstract: A display apparatus includes a display unit, a source driver, a gate driver and a compensation unit. The display unit includes at least a pixel unit. Each pixel unit includes a first transistor, a second transistor, a first capacitor, a second capacitor and an organic light emitting diode. When the pixel unit is operated in a display mode, the pixel unit outputs a sensing voltage including a first parameter having characteristics of the second transistor and a second parameter having characteristics of the organic light emitting diode. The source driver receives a compensation data and accordingly adjusts the next display data. The compensation unit is disposed between the second capacitor and the source driver and electrically coupled between the second end of the second capacitor and the source driver. The compensation unit receives the sensing voltage and outputs the compensation data according to the received sensing voltage.
