    Abstract: A driving controller includes: a logo determiner configured to determine whether or not input image data includes a logo; a logo grayscale value calculator configured to calculate a logo grayscale value of a logo area corresponding to the logo in response to the input image data including the logo; a light emitting element life expectancy determiner configured to determine a life expectancy of a light emitting element corresponding to the logo area; a compensation reference grayscale value generator configured to determine a compensation reference grayscale value according to the life expectancy of the light emitting element corresponding to the logo area; and a logo luminance compensator configured to compare the logo grayscale value to the compensation reference grayscale value to determine whether or not to compensate a luminance of the logo area.

    Abstract: A display apparatus include a display panel and a display panel driver. The display panel includes a panel block. The display panel driver senses a driving current to generate a sensing current, generates a temperature weight of the panel block based on the sensing current and location information of a circuit component, generates a load value of the panel block based on input image data, and generates a predicted temperature of the panel block based on the temperature weight of the panel block and the load value of the panel block.

    Abstract: A driving controller set includes a net power control setter, a data clamper, a data line, and a data driver. The net power control setter may determine a first scale factor for adjusting a grayscale value of (N+1)-th frame data based on a load of N-th frame data and a net power control reference value. N is an integer equal to or greater than two. The data clamper may determine a second scale factor for adjusting a grayscale value of the N-th frame data based on a load of (N−1)-th frame data and the N-th frame data. A data signal may be generated using the first scale factor and/or the second scale factor. The data line may include a conductive material. The data driver may convert the data signal into a data voltage and may output the data voltage to the data line.

    Abstract: An electronic device includes a display panel which includes a plurality of light emitting elements and in which a plurality of areas is defined based on the plurality of light emitting elements, a compensation unit which calculates compensation values for image data provided to each of the plurality of areas, and a control unit which controls the output of the image data provided to the display panel based on the compensation values and the image data, where the control unit may include a correction unit which outputs a correction ratio of each of the plurality of areas based on the compensation values and a comparison unit which determines whether an input current of the image data is in a normal range based on the correction ratio.
