Abstract
Described herein are systems and methods that reduce power consumption for an electronics device including a display. The systems and methods alter video information in a display area and reduce power for a display device when a graphics item is enlarged and the enlargement threatens to increase perceived luminance for the graphics item or increase aggregate luminance for the display area. Altering the video information reduces the luminance of video information in at least the graphics item when enlarged. This may offset perceived luminance gained by human visual processing when an item increases in size. If the graphics item is smaller than the display area after enlargement, then other video information in the display area may also be altered to conserve power.
Claims20
A portable communication device comprising:
- a display corresponding to an organic light emitting diode display;
- and
- at least one processor configured to:
- receive a request to execute an application,
- identify color information corresponding to an image including a graphical user interface with respect to the application, the color information corresponding to at least one of a red pixel, a green pixel, or a blue pixel in relation with displaying of the image via the display,
- adjust the color information based at least in part on a determination that the color information falls into a specified value, and
- display the image according to the adjusted color information via the display such that a power consumption required to display the image is less than a power consumption required without the adjusting.
A portable communication device comprising:
- a display corresponding to an organic light emitting diode display;
- and
- at least one processor configured to:
- receive a request to execute an application,
- identify color information corresponding to a screen including a graphical user interface with respect to the application, the color information corresponding to at least one of a red pixel, a green pixel, or a blue pixel in relation with displaying of the screen via the display,
- adjust the color information based at least in part on a determination that the color information falls into a specified value, and
- display the screen according to the adjusted color information via the display such that luminance required to present the application is less than luminance required without the adjusting.
A non-transitory machine-readable storage device storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
- receiving a request to execute an application at a display apparatus including an organic light emitting diode (OLED) display;
- identifying color information corresponding to a screen including a graphical user interface with respect to the application, the color information corresponding to at least one of a red pixel, a green pixel, or a blue pixel in relation with displaying of the screen via the OLED display;
- adjusting the color information based at least in part on a determination that the color information falls into a specified value;
- and
- displaying the screen according to the adjusted color information via the OLED display such that luminance required to present the application is less than luminance required without the adjusting.
