DISPLAY DEVICE AND DRIVING METHOD THEREOF

摘要

A display device includes: a display unit including pixels; a scan driver configured to provide scan signals to the pixels; a data driver configured to provide data signals to the pixels; a power supply configured to supply a driving power to the pixels; and a controller configured to transmit scan control signals, data control signals, and power control signals for controlling the scan signals, the data signals, and the driving power, respectively. The controller includes: a power consumption calculator configured to calculate power consumption of image data forming a frame; a maximum gray value calculator configured to calculate a maximum gray value of the image data forming the frame; and a voltage level determining unit configured to adjust a voltage level of the driving power in accordance with the maximum gray value, when the calculated power consumption is higher than a reference value.
