Claim of US Patent No. 9,779,648
1. A display device comprising:
a generator configured to generate display chromaticity based on a degradation value, a set chromaticity and device chromaticity,
the display chromaticity being chromaticity of a white point to be displayed on the display device, the degradation value
indicating a degree of degradation of a backlight, the set chromaticity being chromaticity of a white point based on user
setting, the device chromaticity being chromaticity of a white point at which brightness becomes highest in the display device,
wherein the generator is configured to make the display chromaticity approach the device chromaticity from the set chromaticity,
as the degree of degradation indicated by the degradation value increases.
