Abstract: A display device includes pixels connected to scan lines and data lines, each pixel including a driving transistor and at least one light emitting element, and a timing controller configured to generate output data using external input data. The timing controller includes a first compensator configured generate first data by correcting the external input data using at least one of optical measurement information, a threshold voltage of each of the driving transistors, mobility information, dimming information, and temperature information, and an afterimage compensator configured to generate second data based on age information of each light emitting element and the first data, generate third data based on a current amount corresponding to the first data and a current amount corresponding to the second data, and generate the age information by accumulating the third data.
