International Classification:

G09G 3/32
H01L 33/60

Abstract:

A display panel with integrated micro-reflectors. The display panel also includes an array of pixel light sources (e.g., micro-LEDs) electrically coupled to corresponding pixel driver circuits (e.g., FETs). The micro-LEDs produce light and the micro-reflectors reduce the divergence of the light produced by the micro-LEDs. Different designs are possible. The micro-reflectors can have different shapes, include the shape of their sidewalls and the shape of their plan cross-section. The array schemes can also vary, including the number of LEDs per micro-reflector. Different fabrication approaches are also possible. In one approach, a support structure is integrated between micro-LEDs. The sides of the support structure are reflective and serve as the reflective sidewalls of the micro-reflector. Alternately, the LED mesa itself can serve as the support structure.

International Classification:

G02B 3/00

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.

H01L 27/15

Abstract:

Embodiments include a manufacturing method of making a semiconductor device via multiple stages of alignment bonding and substrate removal. One example is an integrated full-color LED display panel, in which multiple wafers with different arrays of LEDs are integrated onto a host wafer with driver circuitry. The driver circuitry typically is an array of pixel drivers that drive individual LEDs on the display panel.
