Abstract: A display device includes a display panel which displays an image, a current compensator and a panel driver. The current compensator calculates a load based on input image data and compensates the input image data to output compensation image data having a target current corresponding to the load. The panel driver drives the display panel based on the compensation image data. The current compensator calculates the load for the input image data based on a combination of load weights calculated by different variables.

Abstract: An embodiment of a display apparatus includes a display panel, a driving controller, and a data driver. In operation the driving controller determines a gain reducing area based on an edge load of input image data corresponding to an edge area of the display panel and compensates a grayscale value of the input image data corresponding to the gain reducing area to generate a data signal. The data driver converts the data signal to a data voltage and outputs the data voltage to the display panel.

Abstract: An organic light emitting diode (“OLED”) display device, which operates in a variable frame mode, includes a display panel including a plurality of pixels, a power management circuit which supplies a power supply voltage to the plurality of pixels, and a controller which determines a panel load, a first representative gray level and a second representative gray level by analyzing input image data, determines an initial level of the power supply voltage based on the panel load and the first representative gray level, and determines a step level of the power supply voltage based on the panel load and the second representative gray level. The power management circuit generates the power supply voltage having the initial level during an active period, and gradually increases a voltage level of the power supply voltage from the initial level based on the step level during a variable blank period.

Abstract: A display device includes a switch, an initialization line, a capacitor, a data line, a first transistor, a second transistor, a driving transistor, and a diode. The capacitor includes a first electrode and a second electrode. To the first electrode through at least the initialization line, the switch may output a first voltage in a first period of a horizontal time and may output a second voltage unequal to the first voltage in a second period of the horizontal time. The first transistor may connect the data line to the first electrode in response to a scan signal. The driving transistor may provide a driving current based on a voltage of the first electrode. The second transistor may connect the initialization line to the second electrode in response to an initialization signal. The diode may emit light based on the driving current.

Abstract: A timing controller of a display device controls a gate driver of the display device. The timing controller includes a clock generator configured to provide a gate clock signal to the gate driver by modulating the gate clock signal with a first modulation pattern in a first frame period and by modulating the gate clock signal with a second modulation pattern different from the first modulation patter in a second frame period.
