Abstract
An information handling system keyboard liquid crystal display (LCD) presents visual images illuminated by light emitting diodes (LEDs) at an underside of the LCD within the keyboard, such as to present function keys or a number pad. A photovoltaic panel placed over the LCD recycles illumination passing through the LCD and also absorbs ambient light to convert the light to a current that is applied to charge a battery of the keyboard.
