Abstract:
1. A display device including a color cluster system, the display device comprising: a first color light-emitting diode (LED) cluster having at least a first LED of a first peak wavelength within a first color range and a second LED of a second different peak wavelength within the first color range, wherein a light path of the first LED is combined at least partially with a light path of the second LED; a second color LED cluster having at least a third LED of a third peak wavelength within a second color range and a fourth LED of a fourth different peak wavelength within the second color range, wherein a light path of the third LED is combined at least partially with a light path of the fourth LED; a third color LED cluster having at least a fifth LED of a fifth peak wavelength within a third color range and a sixth LED of a sixth different peak wavelength within the third color range, wherein a light path of the fifth LED is combined at least partially with a light path of the sixth LED; a first wavelength selection filter configured to reflect light of the first LED cluster along an optical path; a second wavelength selection filter configured to pass light of the first LED cluster and reflect light of the second LED cluster along the optical path; and a plurality of third LED wavelength selection filters configured to filter narrow bandwidths of light centered about the peak wavelengths of the LEDs.
