Abstract
A first light emitting diode has a first driving input, and emits a red color light. A second light emitting diode has a second driving input, and emits a green color light. A third light emitting diode has a third driving input, and emits a blue color light. When a first current is applied to the third driving input, the third light emitting diode produces a first amount of blue light energy. When a second current is applied to the third driving input, the third light emitting diode produces a second amount of the blue light energy. The second amount of blue light energy corresponds to a percentage of blue energy reduction as compared to the amount of first blue light energy.
Claims20
An information handling system comprising:
- a plurality of light emitting diode packages;
- and
- a processor to communicate with the light emitting diode packages, the processor to:
- set a blue light power level to a predefined level within each of the light emitting diode packages of a display within the information handling system, wherein the predefined blue light power level creates a first white light level;
- detect a change in a contextual control variable for the light emitting diode packages;
- and
- reduce the blue light power level from the predefined level to a second level in response to the change in the contextual control variable, wherein the reduction of the blue light power level reduces an amount of blue light energy from the light emitting diode packages.
A method comprising:
- setting a blue light power level to a predefined level within each of a plurality of light emitting diode packages of a display within an information handling system, wherein the predefined blue light power level creates a first white light level;
- detecting a change in a contextual control variable for the light emitting diode packages;
- and
- reducing the blue light power level from the predefined level to a second level in response to the change in the contextual control variable, wherein the reduction of the blue light power level reduces an amount of blue light energy from the light emitting diode packages.
A non-transitory computer-readable medium including code that when executed by a processor performs a method, the method comprising:
- setting a blue light power level to a predefined level within each of a plurality of light emitting diode packages of a display within an information handling system, wherein the predefined blue light power level creates a first white light level;
- detecting a change in a contextual control variable for the light emitting diode packages;
- and
- reducing the blue light power level from the predefined level to a second level in response to the change in the contextual control variable, wherein the reduction of the blue light power level reduces an amount of blue light energy from the light emitting diode packages.
