<p>A display device according to the present invention comprises: a scan driving unit which applies scan signals and light-emission control signals through multiple scan lines and light-emission control lines; a data driving unit which applies data signals through multiple data lines: a power supply unit which applies power through multiple power supply lead-in parts: a pixel unit which includes multiple pixels displaying an image by receiving the scan signals, light-emission control signals, data signals, and power, and is partitioned into multiple sections to correspond to the power supply lead-in parts; and a current-limiting circuit which calculates sectional current values applied to the multiple sections based on the gradation data of an image signal, and outputs a control signal limiting the brightness of the pixel unit if at least one of the sectional current values is above a reference value.</p> |
