Claim 17:
18. 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; and
a data driving circuit configured to receive the converted image data and output a data voltage,
wherein the command signal defines the transforming period and a normal state in which the shape of the display panel is fixed,
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 data driving circuit comprises at least one source driver integrated circuit, and the at least one source driver integrated circuit is mounted on a circuit film in a chip-on-film manner,
wherein the circuit film comprises:
one or more first pins configured to output the data voltage to the display panel;
one or more second pins configured to output a direct current (DC) voltage to the display panel;
one or more third pins electrically connected to the data driving circuit and to which image data converted according to a preset interface format is input;
one or more fourth pins configured to receive the DC voltage and transmit the DC voltage to the one or more second pins, and
wherein voltage levels of DC voltages input to the one or more fourth pins in the transforming period and the normal state are different from each other.
