Image display device and control method thereof

摘要

An image display device is provided in which a difference in color appearance between visual angles can be reduced. The image display device includes: a light-emitting unit including a first light source configured such that a peak wavelength of a spectral spectrum of the light source is within a wavelength region in which a difference between color matching functions of different visual angles is small and a second light source that differs from the first light source; a control unit configured to switch a light source to be lighted to one of the first light source and the second light source based on an instruction; and a display panel that is illuminated by the light-emitting unit.

1. An image display device comprising:
a light-emitting unit including a first light source and a second light source; a setting unit configured to set a display mode of the image display device to any one of a plurality of display modes; a control unit configured to control to light the first light source based on the display mode set by the setting unit and to control to light the second light source based on the display mode set by the setting unit; and a display panel that is illuminated by the light-emitting unit, wherein a difference between color matching functions of plural visual angles in a peak wavelength of a spectrum of the first light source is smaller than that of the second light source, and wherein the control unit is configured to light the first light source in a case where the setting unit sets a first display mode for suppressing a difference in color appearance between the plural visual angles.
