US 2022/0037101 A1 · INFORMATION HANDLING SYSTEM KEYBOARD EMBEDDED MICRO LED BACKLIGHT

Abstract

Information handling system keyboard illumination is provided with micro LEDs disposed below keyboard keys to direct illumination at each key individually. The micro LEDs may be integrated at a bottom surface of a support plate below a keyboard membrane, on top of the support plate within an opening of the membrane or in a spacer layer of the membrane between circuit layers. A diffuser disposed between the micro LED helps to diffuse illumination directed at the key for a more even icon illumination. The diffuser may be integrated with the membrane at an upper circuit layer or over a structure disposed over the micro LED.
