Abstract
In a method for adjusting a refresh rate of a display, a current status of at least one lighting criterion is determined. The refresh rate is then adjusted depending on this determined status. A display module and an electronic device, respectively, comprise a display and a processing component adapted to perform such an adjustment. In a software program product, a software code is stored in a readable medium, the software code performing such an adjustment of the refresh rate of a display when being executed by a processor.
Claims15
A method for adjusting a refresh rate of a display, said method comprising:
- determining a current status of at least one lighting criterion, wherein said at least one lighting criterion comprises a backlight and ambient light, wherein different statuses of said backlight are given by said backlight being switched on or off, and wherein different statuses of said ambient light are given by different intensities of said ambient light;
- and
- adjusting said refresh rate depending on said determined status,
- wherein said refresh rate is set to a higher value when said backlight is determined to be switched on, or said refresh rate is varied at higher values depending on a determined intensity of said ambient light when said backlight is determined to be switched on, and
- wherein said refresh rate is varied at lower values depending on a determined intensity of said ambient light when said backlight is determined to be switched off.
An apparatus comprising:
- a display adapted to operate with different refresh rates;
- and
- a processor configured to determine a current status of at least one lighting criterion and configured to adjust a refresh rate of said display based on said determined status;
- wherein said at least one lighting criterion comprises a backlight and ambient light, wherein different statuses of said backlight are given by said backlight being switched on or off, and wherein different statuses of said ambient light are given by different intensities of said ambient light;
- wherein said processor is configured to set said refresh rate to a higher value when said backlight is determined to be switched on, or to vary said refresh rate at higher values depending on a determined intensity of said ambient light when said backlight is determined to be switched on;
- and
- wherein said processor is configured to vary said refresh rate at lower values depending on a determined intensity of said ambient light when said backlight is determined to be switched off.
A software program product in which a software code for adjusting the refresh rate of a display is stored in a readable medium, said software code realizing the following steps when being executed by a processor:
- determining a current status of at least one lighting criterion, wherein said at least one lighting criterion comprises a backlight and ambient light, wherein different statuses of said backlight are given by said backlight being switched on or off, and wherein different statuses of said ambient light are given by different intensities of said ambient light;
- and
- adjusting said refresh rate depending on said determined status
- wherein said refresh rate is set to a higher value when said backlight is determined to be switched on, or said refresh rate is varied at higher values depending on a determined intensity of said ambient light when said backlight is determined to be switched on;
- and
- wherein said refresh rate is varied at lower values depending on a determined intensity of said ambient light when said backlight is determined to be switched off.
An apparatus comprising:
- means for determining a current status of at least one lighting criterion, wherein said at least one lighting criterion comprises a backlight and ambient light, wherein different statuses of said backlight are given by said backlight being switched on or off, and wherein different statuses of said ambient light are given by different intensities of said ambient light;
- and
- means for adjusting a refresh rate of a display based on said determined status
- by setting said refresh rate to a higher value when said backlight is determined to be switched on, or by varying said refresh rate at higher values depending on a determined intensity of said ambient light when said backlight is determined to be switched on;
- and
- by varying said refresh rate at lower values depending on a determined intensity of said ambient light when said backlight is determined to be switched off.
