A portable electronic device having a rollable display structure is proposed. When the rollable display panel is unrolled from the display drum inside the housing and drawn out of the housing, a self-standing guide unit guides the rollable display panel to be curved in an arc shape so that the rollable display panel stands upright on its own, whereby the rollable display panel may be maintained in an unrolled state without an additional structure. In this way, the size and weight of a product may be reduced, so that portability of the portable electronic device may be improved.

An electronic device includes a display panel including a folding area and a non-folding area adjacent to the folding area, a display controller which controls a driving of the display panel, and a detection sensor disposed adjacent to the folding area and which measures a modulus of the folding area in a folded state of the display panel. The display controller controls the display panel based on a measured modulus in a way such that an image for temperature adjustment is displayed on the display panel.

System for detecting a touch gesture of a user on a detection surface, comprising: a processing unit; and an accelerometer to detect a vibration at the detection surface and generate a vibration signal. The processing unit is configured to: acquire the vibration signal, detect, in the vibration signal, a signal characteristic which can be correlated to the touch gesture of the user, detect, in the vibration signal, a stationarity condition preceding and/or following the detected signal characteristic, and validate the touch gesture in the event that both the signal characteristic and the stationarity condition have been detected. An electrostatic charge sensor may also be used as a further parameter to validate the touch gesture.
