Classification: CPC G | IPC G

Claim 0:
1. A display device comprising:
a display panel including one or more sub-pixels in a display area, the one or more sub-pixels having a light emitting device and a driving transistor configured to drive the light emitting device, and the display panel having a shape that is changed during a transforming period;
a timing controller configured to receive image data and a command signal defining the transforming period, the timing controller configured to convert the image data to output converted image data;
a data driving circuit configured to receive the converted image data and output a data voltage; and
a power management circuit configured to output a first initialization voltage applied to a first initialization voltage supply node and a low potential driving voltage to the display panel,
wherein, in the transforming period, at least one sub-pixel emits light based on the image data input to the timing controller, and emits light with a luminance that is less than a luminance corresponding to a grayscale of the image data,
wherein the command signal defines a transforming period and a normal state in which the shape of the display panel is fixed,
wherein a voltage level of the first initialization voltage output by the power management circuit during the transforming period is greater than a voltage level of the first initialization voltage output by the power management circuit in the normal state.
