Abstract
A display device includes: a first pixel row including n pixels coupled to a first scan line; a second pixel row including m pixels coupled to a second scan line; a first power voltage source for supplying a first power voltage to the pixels of the first pixel row and the second pixel row through a first power voltage line; a current sensor for sensing a value of a line current flowing between the first power voltage line and a selected pixel row among the first pixel row and the second pixel row; and a timing controller for calculating a converted current value of the selected pixel row, wherein n is a natural number, and m is a natural number greater than n.
