Abstract
A rollable display panel and a rollable display device, the rollable display panel including a display region configured to display an image; a non-display region surrounding the display region; and a resistor sensor in the non-display region including sensing material of which resistance values are different by location, wherein the resistor sensor outputs a sensing signal that is regularly changed proportional to a rolling length of the rollable display panel, and a sensor driver that determines a driving region of the rollable display panel based on the sensing signal.
