摘要： A display system includes a source device and a sink device. The source device generates red-color display data, green-color display data, and blue-color display data and transmits first packet data including the red-color display data and a red-color display reference gamma-set, second packet data including the green-color display data and a green-color display reference gamma-set, and third packet data including the blue-color display data and a blue-color display reference gamma-set. The sink device converts the red-color display data, the green-color display data, and the blue-color display data into red-color display data-voltages, green-color display data-voltages, and blue-color display data-voltages and displays an image using the red-color display data-voltages, the green-color display data-voltages, and the blue-color display data-voltages. The sink device generates red-color display gamma-voltages, green-color display gamma-voltages, and blue-color display gamma-voltages based on the red-color display reference gamma-set, the green-color display reference gamma-set, and the blue-color display reference gamma-set, respectively.
