Abstract:
A timed programmable control alters signals between an electronic device and a viewing screen to lower or eliminate a signal for a specific color on the screen at specific times. Eliminating or lowering blue color on the screen allows normal production of melatonin prior to normal sleep times to permit normal sleep cycles. The control may be a microcontroller or simple switch inside a locked box, a video card, or software to control light pixel values in memory, VGA signals, and digital to analog conversions.
