Abstract: A display apparatus includes a display panel including a plurality of pixels, and a driver which receives input image data, generates final image data by compensating the input image data to increase luminances of pixels disposed in at least one edge portion of the display panel among the plurality of pixels, and drives the display panel based on the final image data. The input image data for a pixel of the pixels is compensated based on a compensation constant determined according to a position of the pixel when the input image data for the pixel represents a gray level higher than or equal to a first reference gray level, and is compensated based on a reduced compensation constant that is reduced from the determined compensation constant when the input image data for the pixel represents the gray level lower than the first reference gray level.

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 backlight unit of a display device includes a power converter to generate a light source voltage in response to a power control signal, a light emitting element connected between a first node and a second node, and a light source controller connected to the second node and to output the power control signal in response to a dimming signal. The light emitting element receives the light source power voltage through the first node. When a feedback voltage of the second node is lower than a first reference voltage, the light source controller outputs the power control signal having a first pulse width based on the feedback voltage and the dimming signal. When the feedback voltage is higher than the first reference voltage, the light source controller outputs the power control signal having a second pulse width based on a voltage lower than the feedback voltage and the dimming signal.
