DISPLAY DEVICE, DISPLAY SYSTEM, IMAGE OUTPUT DEVICE, AND METHOD FOR CONTROLLING DISPLAY DEVICE
First Claim
1. A display device comprising:
- an emission part including a first light source emitting a first light, a second light source emitting a second light having a longer wavelength than the first light, and a fluorescent substance which is excited by the first light and the second light so as to emit a third light; and
a controller configured to generate a drive value of the first light source and a drive value of the second light source based on a luminance of the first light, a luminance of the second light, a luminance of the third light, a first target luminance for the first light source, a second target luminance for the second light source, and a third target luminance for the fluorescent substance, thus controlling two light sources based on the drive values of the first and second light sources.
