Abstract: An electronic reading device can include an adjustable RGBW front light and an ambient light sensor. Additionally, the electronic reading device can include circuitry configured to receive a signal from the ambient light sensor corresponding to a detected ambient light level, automatically display a default brightness level based on the detected ambient light level, determine if the brightness level is manually adjusted, automatically adjust the relative brightness based on the manually adjusted brightness level when the ambient light level changes, and update preferred relative settings to correspond to the manual adjustment.

Abstract: An electronic device includes an adjustable RGBW front light. The electronic device additional includes circuitry configured to determine if a transition between phases has occurred, the phases being based on a time of day, automatically display a predetermined screen color temperature via the adjustable RGBW front light in response to the transition between phases, and automatically adjust a predetermined mixture of light to be displayed via the adjustable RGBW front light such that the predetermined screen color temperature does not change in response to a change in a brightness level of the electronic device.

Abstract: An electronic reading device can include an adjustable RGBW front light and an ambient light sensor. Additionally, the electronic reading device can include circuitry configured to determine if a transition between phases has occurred, wherein the phases include a night phase, a sunrise transition phase, a daytime phase, and a sunset transition phase, automatically display a predetermined screen color temperature via the adjustable RGBW front light in response to the transition between phases, determine if a brightness level has changed, and automatically adjust a predetermined mixture of light to be displayed via the adjustable RGBW front light such that the screen color temperature does not change in response to the changing brightness level.
