Abstract: A display apparatus includes a driving controller, a data driver and a display panel. The driving controller is configured to determine an average load of a unit area based on an average grayscale value of the unit area and a pixel area ratio of the unit area, to determine a temperature diffusion load of the unit area based on average loads, temperature diffusion ratios and weight ratios of adjacent unit areas adjacent to the unit area and to compensate input image data based on the average load of the unit area and the temperature diffusion load of the unit area to generate a compensated data signal. The data driver is configured to convert the compensated data signal into a data voltage. The display panel is configured to display an image based on the data voltage.

Abstract: A display device includes a display panel with a first display area having a first light transmittance and a second display area having a second light transmittance higher than the first light transmittance. The display device also includes a driving controller which divides an image signal into a first image signal corresponding to a first pixel unit in the first display area and a second image signal corresponding to a second pixel unit and a non-pixel unit adjacent to the second pixel unit. The display controller calculates the second image signal with a preset kernel matrix, and outputs a data signal corresponding to the second pixel unit in the second display area.
