Abstract: A display device and method of driving the same are disclosed. The display device that transmits signals between a system board section and a circuit board section through an interface and uses Panel Self-Refresh (hereinafter, abbreviated as ‘PSR’) to reduce power consumption, the circuit board section comprising a PSR controller that, when a PSR On signal is supplied from the system board section, changes the operating frequency of a gate driver and data driver to a frequency higher than a reference frequency for driving the panel with PSR On, set by the system board section.

Abstract: A display device capable of driving at low speed is disclosed. Pixels connected to a first data line on odd-numbered display lines of a display panel are positioned on one side of the left and right sides of the first data line, and pixels connected to the first data line on even-numbered display lines of the display panel are positioned on the other side of the first data line based on a Z-inversion scheme. When a mode conversion control signal for switching to an interlaced low speed driving mode is input during a normal drive, in which a length of one frame is set to P, a timing controller expands a length of one frame for a low speed drive to (n×P), where n is a positive integer equal to or greater than 2 and assigns a length P to each of n sub-frames of the one frame.

Abstract: Disclosed is an electroluminescent display device using a variable refresh rate (VRR) mode. The purpose of the present disclosure is to reduce the occurrence of a difference in luminance at a time point of a refresh rate change, thereby preventing viewers from perceiving the variation of the refresh rate.
