Abstract
An information handling system peripheral display provides backlight to a liquid crystal display panel through a light guide plate with illumination from a light emitting diode package having plural evenly spaced light emitting diodes disposed in a spaced relationship along one side of the light guide plate. For insert molded coupling devices, a midframe structure integrates spacers at opposing ends of the bottom side of the light guide plate to maintain the spaced relationship without any additional intervening structures between the light emitting diode package and light guide plate along the bottom side between the opposing ends.
