An organic light-emitting display device and a method for driving the same are provided. The organic light-emitting display device analyzes input image data in unit of a window mask to detect a halftone data block, adjusts a voltage corresponding to grayscale 0 of center data disposed at the center of the halftone data block to a voltage higher than 0V, and adjusts the voltage corresponding to grayscale 0 in a data block other than the halftone data block to 0V, such that a data voltage swing width at low grayscales can be reduced so as to prevent voltage drop in pixels, thereby improving picture quality.

Organic light-emitting display and method for driving the same

Disclosed is a driving method of a display device that includes, for example, setting a luminance increase gain based on a chroma of an RGB data of an input image; modulating the RGB data of the input image based on the luminance increase gain to generate an RGB data of a first image; substituting a W data for common components of the RGB data of the first image and converting the RGB data of the first image to an RGBW data of a second image; and encoding the RGBW data of the second image into an RGBW data of a third image such that a number of bits of the RGBW data of the third image is less than a number of bits of the RGBW data of the second image.

Display device and driving method thereof

Disclosed is an apparatus and method for driving an organic light emitting display device which facilitates to control current consumption of a display panel according to a temperature of the display panel including a light emitting device or a surrounding temperature of the display panel, the apparatus comprising the display panel including the plurality of pixels provided with the plurality of light emitting devices which emit light according to a current, a temperature sensing unit for generating temperature data by sensing a temperature of the display panel or surrounding temperature; and a panel driver for controlling a data signal to be supplied to each pixel so as to make current consumption of the display panel be lower than a preset current limit value on the basis of input data and temperature data.

Apparatus and method for driving organic light emitting display device

Disclosed is an apparatus and method for driving an organic light emitting display device which controls a current flowing in a display panel to be lower than a current limit value, the apparatus comprising a display panel including a plurality of pixels, wherein each pixel is provided with a light emitting device which emits light according to a current corresponding to a data voltage; and a panel driver that predicts a panel current value flowing in the display panel on the basis of data of a preceding frame and data of a current frame simultaneously displayed on the display panel, and controls the data voltage to be displayed on the display panel so as to make the panel current value be lower than a preset current limit value.
