Abstract: A display device includes a display unit including a pixel which displays an image based on a first power voltage and a data signal, a gamma voltage generator which generates gamma voltages, and a data driver which generates the signal using the gamma voltages and provides the data signal to the pixel. The gamma voltage generator generates first and second reference voltages, generates first and second corrected reference voltages by correcting the first and second reference voltages using a target voltage and an external power voltage provided from the display unit in correspondence with the first power voltage, and generates the gamma voltages by dividing the first and second corrected reference voltages. The gamma voltage generator sets the target voltage based on at least one selected from the first reference voltage, the second reference voltage, and a ground voltage.

Abstract: A display device includes a clock oscillator, a register, and a data driver. The clock oscillator generates a clock signal. The register stores a clock signal parameter for the clock signal. The data driver determines a number of clock signals in 1 horizontal period based on the clock signal parameter, and applies data signals to data lines connected to a plurality of pixels based on the 1 horizontal period.

Abstract: A display driver includes a memory, a receiver, an image output unit, a controller, and an image mode selection unit. The memory stores a video signal. The receiver receives the video signal and a first control signal from a host processor, where the first control signal corresponds to the video signal. The image output unit processes the video signal stored in the memory and outputs the processed video signal to a display unit. The controller controls the image output unit based on an image mode to display an image corresponding to the video signal. The image mode selection unit detects the first control signal and a second control signal from the controller, and changes the image mode based on the first control signal and second control signal.
