COLOR MIXING DEVICE AND DISPLAY DEVICE

摘要

A color mixing device and a display device are configured to represent the color white in a consistent fashion, even in low-luminance areas. These devices are provided with: a red light source for outputting red light at optical intensity in response to a first current presented thereto; a green light source for outputting green light at optical intensity in response to a second current presented thereto; a blue light source for outputting blue light at optical intensity in response to a third current presented thereto; and a color mixing means for color mixing of the red light, the green light, and the blue light together. A light attenuating part transmits or reflects the blue light, bringing about attenuation and advance thereof in the output direction. The blue light output by the blue light source is attenuated to a greater extent than the light of the other colors during output.

主权项

1. A color mixing device, comprising:
a red light source which emits red light at optical intensity in response to a first current to be supplied; a green light source which emits green light at optical intensity in response to a second current to be supplied; a blue light source which emits blue light at optical intensity in response to a third current to be supplied; a light source control part which controls the light sources; and color mixing means for mixing the red light, the green light, and the blue light in all, wherein a light attenuating member which attenuates the blue light emitted from the blue light source is provided.
