Abstract: A display device includes a memory, a signal controller, and a voltage generator. A plurality of data is stored in the memory. The signal controller detects a frame rate of an externally applied image data signal, selects data corresponding to the detected frame rate among the plurality of data, and outputs a control signal corresponding to the selected data. The voltage generator includes a DC-DC converter for determining an output voltage in correspondence to the control signal and a feedback circuit for determining a current flowing inside and a frequency of an outputted signal in correspondence to the control signal.

Abstract: A display device includes: a display panel; a driving frequency converter circuit configured to convert a driving frequency according to an input image data. A common voltage controller outputs a common voltage data corresponding to the driving frequency; and a common voltage generator receives the common voltage data to generate a common voltage and outputs the common voltage to the display panel. The common voltage has an inclined waveform within an integer multiple of a frame period.

Abstract: A display device includes: a system unit which output image signals corresponding to frames and a first or second image control signal based on the image signals; an eDP reception unit which receives the image signals and the first or second image control signal from the system unit, provides a still image signal based on the first image control signal, and provides the image signals based on the second image control signal; and a frame memory which stores the still image signal and outputs the still image signal while the first image control signal is provided to the eDP reception unit, where the still image signal is one of the image signals; the eDP reception unit recovers first clock signals based on the image signals; and the frame memory outputs the still image signal based on a second clock signal generated based on the first clock signal.
