Abstract: A display device including: a controller including: a zone splitting block configured to divide input image data into a plurality of partial image data respectively corresponding to a plurality of partial panel zones of the display panel; a plurality of panel zone frequency deciding blocks configured to determine a plurality of driving frequencies for the plurality of partial panel zones by analyzing the plurality of partial image data, respectively; a non-driving period setting block configured to classify a plurality of frame periods into a driving frame period and a non-driving frame period based on a maximum driving frequency of the plurality of driving frequencies; and a scan driver control block configured to provide the scan driver input signal to the scan driver in the driving frame period, and to not provide the scan driver input signal to the scan driver in the non-driving frame period.

Abstract: A display device includes a display panel including a plurality of pixels and a display panel driver configured to drive the display panel. Here, the display panel driver is configured to receive input image data, to drive the display panel at a first driving frequency when the input image data corresponds to a moving image, and to select one of a plurality of flicker lookup tables based on the first driving frequency and drive the display panel at a second driving frequency based on the flicker lookup table when the input image data corresponds to a still image.

Abstract: A display device including: a display panel including a pixel connected to a first scan line, second scan line, and data line, the pixel including: a first switch connected to the first scan line; a second switch connected to the second scan line; and a light emitting element; a low-frequency driving controller to output a power control signal having a first level in a first mode and a second power control signal having a second level in a second mode; a scan driver including first and second scan drivers to drive the first and second scan lines, wherein one of the first and second scan drivers operates in the second mode; and a data driver to operate in the second mode in response to the power control signal having the second level, wherein the data driver operates at a frequency lower than a reference frequency in the second mode.
