Abstract: A display device includes a driving controller sensing a pattern of first image signals from a source external to the driving controller and outputting a compensation selection signal corresponding to the sensed pattern. A voltage generator generates a driving power voltage in response to the compensation selection signal. The voltage generator includes a power converter generating the driving power voltage in response to a power control signal, a comparator comparing the driving power voltage with a reference voltage to output a feedback signal to a first node, and a compensation circuit including a plurality of compensation units. A selected compensation unit is connected to the first node, and a power control circuit outputs the power control signal in response to the feedback signal. The slew rate of the feedback signal may be controlled by a compensation circuit to remove a ripple component from the driving power voltage.

Abstract: A display apparatus includes a display panel, a gate driver and a data driver. The display panel displays an image and includes first sub-pixels which display a first color, second sub-pixels which display a second color different from the first color, first gate lines to which only the first sub-pixels are connected, second gate lines to which only the second sub-pixels are connected, and data lines. The gate sequentially applies first gate signals only to the first gate lines during a first duration of a first frame, and sequentially applies second gate signals only to the second gate lines during a second duration of the first frame, where the second duration is subsequent to the first duration. The data driver outputs data voltages to the data lines based on input image data in synchronization with a driving sequence of the first and second gate lines.
