摘要： A display apparatus that includes a controller, a gate driver, a data driver, and a gamma voltage generator is presented. The controller generates image data and a data clock to drive a display unit based on original data and an original control signal received from an exterior. The gate driver provides an image data signal to a data interconnection provided in the display unit. The data driver provides a gate signal to a gate interconnection provided in the display unit. The gamma voltage generator generates gamma voltages serving as a reference in response to the data driver providing the gate signal to the display unit. The gamma voltage generator selectively outputs sub-reference voltages, which are divided from an external reference voltage, and a specific voltage, which is generated from the gamma voltage generator, as the gamma voltages.
