Abstract

Various embodiments include a display panel with integrated micro lens array. The display panel typically includes an array of pixel light sources (e.g., LEDs) electrically coupled to corresponding pixel driver circuits (e.g., FETs). The array of micro lenses are aligned to the pixel light sources and positioned to reduce the divergence of light produced by the pixel light sources. The display panel may also include an integrated optical spacer to maintain the positioning between the micro lenses and pixel driver circuits.
