A light supply method is provided. The light supply method includes: providing a first driving signal in a first time interval by a driver and providing a first time-varying light by a light source module in response to the first driving signal; providing a second driving signal in a second time interval after the first time interval by the driver and providing a first fixed light by the light source module in response to the second driving signal; and providing a third driving signal by the driver in a third time interval after the second time interval and providing a second time-varying light by the light source module in response to the third driving signal.

A user interface display may have a display and may have a backlight that lights the display. The display may implement pixels to generate colors and images. The display may be backlit. The backlight may use pixels having emitters to generate different color backlighting. In various instances, the display or the backlight or both may include a deep blue emitter. The blue emitter may be used in combination with red and green pixels elements to generate different colors. By implementing deep blue emitters rather than conventional blue (e.g., cyan) emitters, the effects of cyan light on a viewer's circadian rhythm may be limited or eliminated. Moreover, by implementing deep blue emitters, the effects of cyan light on a viewer's circadian rhythm may be varied, while the colors and images are reproduced for viewing without introducing significant color distortion.

Embodiments of the present disclosure provide systems, apparatuses and methods for regulation hormone production in mammals. Examples include but are not limited to by creating electro-magnetic wave emission pulse trains (photons) of individual color spectrums in sufficient intensity to drive hormone production in a mammal, using a characteristic frequency or pattern to minimize the required input power necessary to regulate hormone production, while also allowing for the monitoring of the power consumption and other variables of the system. By controlling the duty cycle, intensity, wavelength band and frequency of photon signals to a mammal, production of specific hormones can be regulated through the cycling between blue, green, yellow, near-red, far-red, infrared and ultra violet photon modulation.
