Abstract
A display device for increasing brightness of an image generation, including a color cluster system, is provided. The system includes a first color LED cluster having at least a first LED of a first wavelength within a first color range and a second LED of a second different wavelength within the first color range. The light from the first LED may be combined at least partially with light from the second LED The system further comprises a second color LED cluster having at least a first LED of a first wavelength within a second color range and a second LED of a second different wavelength within the second color range. In the second color LED cluster, the light from the first LED may be combined at least partially with light from the second LED.
Claims26
A display device comprising:
- a first light source of a first peak wavelength within a first color range;
- a second light source of a second peak wavelength within the first color range, the second peak wavelength is different from the first peak wavelength;
- a third light source of a third peak wavelength within a second color range;
- a fourth light source of a fourth peak wavelength within the second color range, the fourth peak wavelength is different from the third peak wavelength;
- and
- a first wavelength selection filter configured to filter a narrow bandwidth of light from the first light source.
A display device comprising:
- a first color light source cluster having at least a first light source of a first peak wavelength within a first color range and a second light source of a second peak wavelength within the first color range, the second peak wavelength being different from the first peak wavelength;
- a second color light source cluster having at least a third light source of a third peak wavelength within a second color range and a fourth light source of a fourth peak wavelength within the second color range, the fourth peak wavelength being different from the third peak wavelength;
- and
- a fifth light source of a fifth peak wavelength within a third color range.
