Abstract
An electronic device according to an embodiment of the present invention comprises: a housing; a display panel disposed inside the housing; a display driver circuit electrically connected to the display panel; and a processor for generating a background image output through the display panel to transmit the same to the display driver circuit.
Claims15
An electronic device comprising:
- a housing,
- a display panel arranged in the housing,
- a display driving circuit electrically connected to the display panel, and
- a processor configured to generate a background image output through the display panel and transmit the background image to the display driving circuit,
- wherein the display driving circuit is configured to:
- determine whether a first object is displayed in a first area of the background image that is not exposed to an outside by the housing when the background image is received,
- generate a partial image having a size smaller than a size of the background image when the first object is not displayed as the determination result, and
- merge the partial image and a second area of the background image that is exposed to the outside and output a merging result through the display panel.

A display driving circuit comprising:
- a receiving circuit configured to sequentially receive a first background image and a second background image from an external processor,
- an up-scaler electrically connected to the receiving circuit and extract a first tracking point and a second tracking point generated in some areas of the first background image and the second background image, and
- a controller electrically connected to the up-scaler,
- wherein the controller is configured to:
- generate a first partial image when the first background image is received from the receiving circuit,
- output the first partial image at a position corresponding to a coordinate value of the first tracking point on the first background image,
- generate a second partial image when the second background image is received from the receiving circuit,
- calculate a difference between the coordinate values of the first tracking point and the second tracking point,
- move the second partial image from the coordinate value of the first tracking point by a distance corresponding to the difference between the coordinate values of the first tracking point and the second tracking point and output the second partial image onto the second background image.
