PATTERNED REFLECTIVE GRIDS FOR LED ARRAYS AND DISPLAYS

LED arrays comprise patterned reflective grids that enhance the contrast ratio between adjacent pixels or adjacent groups of pixels in the array. The pattern on the reflective grid may also improve adhesion between the reflective grid and one or more layers of material disposed on and attached to th...

More Information
Summary:LED arrays comprise patterned reflective grids that enhance the contrast ratio between adjacent pixels or adjacent groups of pixels in the array. The pattern on the reflective grid may also improve adhesion between the reflective grid and one or more layers of material disposed on and attached to the reflective grid. The reflective grid may be formed, for example, as a reflective metal grid, a grid of dielectric reflectors, or a grid of distributed Bragg reflectors (DBRs). If formed as a metal grid, the reflective grid may provide electrical contact to one side of the LED diode junctions. This specification also discloses fabrication processes for such LED arrays.
