Abstract
A method of controlling the temperature of a display device which includes a display panel having a plurality of light emitting elements arrayed in a matrix form, and a plurality of driver ICs is disclosed. The method includes the steps of: generating temperature information of the driver IC by detecting an exothermic temperature caused by the consumption power of each of the driver ICs; and controlling a supply current to the light emitting elements by comparing the temperature information with temperature information added with weighted position information to perform weighting in such a manner that exothermic temperature detection data of the driver IC becomes larger for the driver IC corresponding to an upper area of the display panel by using a look-up table previously formed and stored.
