Laser diode backlighting of LC display with at least one diode generating light beam having divergence angle and with display panel having beam spreader to increase divergence

摘要

An LCD display includes a planar array of transmissive liquid crystal display (LCD) devices, and at least one laser diode device spaced apart from the planar array of LCD devices and configured to illuminate at least a subset of the LCD devices of the planar array of LCD devices such that, in operation, the laser diode device provides backlighting for the subset of LCD devices of the planar array of LCD devices.
