<p>A display system including a display panel having a first major surface and a second major surface and a lighting system adapted to provide uniform luminance proximal to the display panel is disclosed. The lighting system includes an illuminating substrate having a first major surface with reflective coating and a second major surface. The illuminating substrate defines an array of mounting holes, each hole occupied by an LED module. An array of light emitting diode (LED) modules are affixed to the illuminating substrate. each module including at least one light emitting diode adapted to emit light. The lighting system can also include a diffusant layer which can be optically coupled to the illuminating substrate by soft optical gel and is placed close to or made to contact the display panel. The optical gel may contain phosphors or other optical substance for added optical performance to the lighting system. The diffusant layer has beveled edges at critical angle of refraction or coated with reflective material to minimize light loss at its edges. Each of the LED modules includes at least one LED chip, conductive traces connected to the LED chip and a heat sink.</p> |
