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.

First claim

1 . An electronic device, comprising:
an adjustable RGBW front light; and 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.

2 . The electronic device of claim 1 , wherein the phases include a night phase, the night phase being from a bedtime to a predetermined sunrise, the bedtime being a default setting or manually selected by a user.

3 . The electronic device of claim 2 , wherein the predetermined screen color temperature of the night phase is 1900K.

4 . The electronic device of claim 2 , wherein the phases include a sunrise transition phase, the sunrise transition phase being from the predetermined sunrise to a start of a daytime phase such that the predetermined screen color temperature transitions from 1900K at the beginning of the sunrise transition phase to 6400K at the beginning of the daytime phase.

5 . The electronic device of claim 1 , wherein the phases include a sunset transition phase, the sunset transition phase being from a predetermined beginning of the sunset transition phase to a bedtime, wherein the bedtime is a beginning of a night phase, such that the predetermined screen color temperature transitions from 6400K at the beginning of the sunset transition phase to 1900K at the bedtime.

6 . The electronic device of claim 1 , wherein the circuitry is further configured to
automatically increase the screen color temperature at a first predetermined rate of change based on the transition between phases being a sunrise transition phase, and automatically decrease the screen color temperature at a second predetermined rate of change based on the transition between phases being a sunset transition phase.

7 . The electronic device of claim 1 , wherein the circuitry is further configured to
determine if the screen color temperature is manually adjusted during the transition between phases, and in response to the screen color temperature being manually adjusted during the transition between phases, delay a start of a next phase by one hour or continue the transition in the phase from the manually adjusted screen color temperature.

8 . The electronic device of claim 1 , wherein the circuitry is further configured to
determine if the screen color temperature is manually adjusted during one of the phases, display the manually adjusted screen color temperature until an end of the phase, and cause a starting point of a next phase to be the manually adjusted screen color temperature.

9 . The electronic device of claim 1 , wherein the circuitry is further configured to
determine if the screen color temperature is manually adjusted to less than 1900K, display the manually adjusted screen color temperature until a beginning of a predetermined subsequent transition between phases, and cause the starting point of the predetermined subsequent transition between phases to be the manually adjusted screen color temperature.

10 . A method, comprising:
determining, by processing circuitry, if a transition between phases has occurred, the phases being based on a time of day, automatically displaying, by the processing circuitry, a predetermined screen color temperature via the adjustable RGBW front light in response to the transition between phases, and automatically adjusting, by the processing circuitry, 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 an electronic device.

11 . The method of claim 10 , wherein the phases include a night phase, the night phase being from a bedtime to a predetermined sunrise, the bedtime being a default setting or manually selected by a user, wherein the predetermined screen color temperature of the night phase is 1900K.

12 . The method of claim 11 , wherein the phases include a sunrise transition phase, the sunrise transition phase being from the predetermined sunrise to a start of a daytime phase such that the predetermined screen color temperature transitions from 1900K at the beginning of the sunrise transition phase to 6400K at the beginning of the daytime phase.

13 . The method of claim 10 , wherein the phases include a sunset transition phase, the sunset transition phase being from a predetermined beginning of the sunset transition phase to a bedtime, wherein the bedtime is a beginning of a night phase, such that the predetermined screen color temperature transitions from 6400K at the beginning of the sunset transition phase to 1900K at the bedtime.

14 . The method of claim 10 , further comprising:
automatically increasing the screen color temperature at a first predetermined rate of change based on the transition between phases being a sunrise transition phase, and automatically decreasing the screen color temperature at a second predetermined rate of change based on the transition between phases being a sunset transition phase.

15 . The method of claim 10 , further comprising:
determining if the screen color temperature is manually adjusted during the transition between phases, and in response to the screen color temperature being manually adjusted during the transition between phases, delaying a start of a next phase by one hour or continuing the transition in the phase from the manually adjusted screen color temperature.

16 . The method of claim 10 , further comprising:
determining if the screen color temperature is manually adjusted during one of the phases, displaying the manually adjusted screen color temperature until an end of the phase, and causing a starting point of a next phase to be the manually adjusted screen color temperature.

17 . The method of claim 10 , further comprising:
determining if the screen color temperature is manually adjusted to less than 1900K, displaying the manually adjusted screen color temperature until a beginning of a predetermined subsequent transition between phases, and causing the starting point of the predetermined subsequent transition between phases to be the manually adjusted screen color temperature.

18 . A non-transitory computer-readable storage medium storing computer-readable instructions thereon which, when executed by a computer, cause the computer to perform a method, the method comprising:
determining, by processing circuitry, if a transition between phases has occurred, the phases being based on a time of day, automatically displaying, by the processing circuitry, a predetermined screen color temperature via the adjustable RGBW front light in response to the transition between phases, and automatically adjusting, by the processing circuitry, 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 an electronic device.

19 . The non-transitory computer-readable storage medium of claim 18 , further comprising:
determining if the screen color temperature is manually adjusted during the transition between phases, and in response to t
