A display device includes a display panel which displays an image, and a panel driving block which receives a control signal and generating a criterion point signal including information about a criterion point for adjusting luminance of the image based on the control signal. The panel driving block receives image signals, generates a correction value based on distance information about a location of the display panel, at which each of the image signals is displayed, and the criterion point, and generates correction image signals by converting the image signals based on the correction value.

Display device

A display device includes a display panel including a first pixel and a second pixel, a reference gamma generator configured to generate a first reference gamma voltage and a second reference gamma voltage based on a driving mode, a stain compensator configured to output a stain compensating data that compensates a stain of an image data based on the driving mode, and a data driver configured to generate a first data voltage provided to the first pixel based on the first reference gamma voltage and the stain compensating data and a second data voltage provided to the second pixel based on the second reference gamma voltage and the stain compensating data.

A display apparatus includes a controller which generates control signals and outputs image data, a compensating circuit which receives a portion of the control signals from the controller and generates a compensation signal, a voltage generating circuit which converts an input voltage to a driving voltage and increases or decreases a voltage level of the driving voltage in a frame period in response to the compensation signal, a driving part which receives the control signals and the image data from the controller and receives the driving voltage from the voltage generating circuit to generate a panel driving signal, and a display panel which receives the panel driving signal from the driving part to display an image.

Display apparatus having signal delay compensation

A method of driving a display panel includes outputting a gate signal to the display panel, varying a slew rate of a data voltage to be output to the display panel according to a position in the display panel at which the data voltage is to be applied, outputting the data voltage having the varied slew rate to the display panel, and displaying a grayscale on the display panel in response to the gate signal and the data voltage having the varied slew rate.

Method of driving a display panel capable of compensating for a difference in charging rates between pixels, and a display apparatus for performing the same

A display apparatus includes pixels connected to gate lines and data lines. Among the pixels arranged in k-th and (k+1)th columns between j-th and (j+1)th data lines, the pixels arranged in the k-th column are connected to one data line of the j-th and (j+1)th data lines, the pixels arranged in the (k+1)th column are connected to the other data line of the j-th and (j+1)th data lines, and the pixels arranged in the k-th and (k+1)th columns are alternately connected to the j-th and (j+1)th data lines in a unit of two pixels.
