DEVICE AND METHOD FOR CONTROLLING A BACKLIT DISPLAY

摘要

A device and method for controlling a display. The method includes receiving image data, determining backlight illumination intensity in response to an allowed image degradation level parameter and to ambient light, and determining a display refresh parameter in response to a temperature parameter.;A method and device for controlling a display, the device includes: a frame buffer adapted to receive image data, a processor adapted to receive a power parameter and an allowed image degradation level parameter, and an image converter that is adapted to perform a linear image conversion and a non-linear image conversion. The processor is adapted to determine which conversion to perform in response to a power parameter.

1. A method in an electronic device for controlling a display, the method comprises:
receiving image data; determining backlight illumination intensity in response to an allowed image degradation level parameter and to ambient light; backlighting the display according to the backlight illumination intensity; determining a display refresh parameter in response to a temperature parameter and to arrival of the image data to a frame buffer, wherein, when the frame buffer was updated during a most recent refresh cycle, a next refresh cycle starts immediately, and, when the frame buffer was not updated during the most recent refresh cycle, the next refresh cycle starts after a predefined delay; and displaying an image based on the image data on the display according to the display refresh parameter.
