Abstract
A display device includes a display panel, light emitting elements, a temperature detector, and an image processing circuit. The light emitting elements are disposed in a matrix form on the display panel, a luminance of light emitting elements being controlled by a current value. The temperature detector detects a rise in temperature caused by a consumption power of a driver IC and outputs temperature information, the driver IC being configured for supplying current to the light emitting elements. The image processing circuit controls a supply current to the light emitting elements using the temperature information output from the temperature detector.
