Claims21
1-69. (canceled)
A light emitting diode (LED) display, comprising:
- a color converter configured to change wavelength of light, the color converter including:
- a color conversion layer;
- and
- a long pass filter on the color conversion layer, wherein the long pass filter allows light converted by the color conversion layer to pass, and recycles unconverted light;
- a micro-LED array configured to pump light into the color converter, wherein the array comprises a plurality of LEDs having a dimension between 0.5 μm to 100 μm;
- and
- a backplane control for the micro-LED array, the color conversion layer of the color converter producing light at a longer wavelength than the pumped light from the micro-LED array.

A light emitting diode (LED) display, comprising:
- a color converter configured to change wavelength of light, the color converter including:
- a color conversion layer;
- and
- a long pass filter on the color conversion layer, wherein the long pass filter allows light converted by the color conversion layer to pass, and recycles unconverted light;
- a micro-LED array configured to pump light into the color converter, wherein the array comprises a plurality of LEDs that generate substantially blue or ultraviolet (UV) light, and the color converter converts the light generated by the array into substantially red light;
- and
- a backplane control for the micro-LED array.

- a long pass filter on the color conversion layer, wherein the long pass filter allows light converted by the color conversion layer to pass, and recycles unconverted light;
- a micro-LED array configured to pump light into the color converter, wherein the array comprises a plurality of LEDs that generate substantially blue or ultraviolet (UV) light, and the color converter converts the light generated by the array into substantially green light;
- and
- a backplane control for the micro-LED array.
4 more elements
A light emitting diode (LED) display, comprising:
- a first micro-LED array configured to pump light into a first color converter, wherein the first array generates substantially blue or ultraviolet (UV) light, and the first color converter converts the light generated by the first array into substantially red light;
- and
- a second micro-LED array that generates substantially blue light;
- wherein converted light from the first array correspond to red subpixels, light from the second array correspond to blue subpixels, and the red and blue subpixels combine to form display pixels of the LED display.
