The present disclosure relates to display devices and methods of driving the display devices. In accordance with embodiments of the present disclosure, it is possible to improve image quality of a display device by reducing a sensing time for sensing one or more characteristic values of at least one driving transistor disposed in at least one sub-pixel. Further, it is possible to perform optimal sensing and compensation for at least one driving transistor by setting a minimum sensing time for one or more characteristic values of the at least one driving transistor and changing the sensing time according to a sensing available time of the display device.

Display device and method for driving the same

Disclosed is a multi-display in which light emitting display apparatuses share information for varying a position of an image. The multi-display includes: at least two light emitting display apparatuses; and a distributing device distributing pieces of multi-image data transmitted from an external system to the light emitting display apparatuses, wherein a first controller controlling a function of a first light emitting display apparatus among the light emitting display apparatuses shares information for varying a position of an image with controllers controlling functions of the other light emitting display apparatuses. According to the multi-display of the present disclosure, even if the multi-image is shifted in various directions in order to prevent deterioration of the light emitting display apparatuses in the multi-display, a lossy image may be minimized or reduced.

Multi-display

A controller, an organic light-emitting display panel, an organic light-emitting display device, and a method of driving the same able to compensate for the dropped driving voltage, thereby preventing image quality from being degraded due to the dropped driving voltage.
