  • Patent number: 10965840
    Abstract: A display and a color correction method are disclosed. The display includes a panel and a backlight module. The color correction method includes steps of: (a) sensing a real-time backlight intensity of the backlight module; (b) increasing a backlight intensity of the backlight module when the real-time backlight intensity is different from a standard backlight intensity of the backlight module; (c) sensing a compensated backlight intensity of the backlight module and estimating a first real-time color information of the panel according to the compensated backlight intensity and a first panel color characteristic information, wherein the first panel color characteristic information corresponds to the penetration characteristics of the panel; and (d) estimating a first color gain compensation value for the panel according to the first real-time color information and compensating the colors displayed on the panel when the panel displaying an image according to the first color gain compensation value.

  • Patent number: 10636367
    Abstract: A display and a color correction method are disclosed. The display includes a panel, a backlight module, a first sensing unit, a second sensing unit and a processing module. The first sensing unit senses a real-time ambient light information of an environment that the display is located in. The processing module estimates a target display lightness according to the real-time ambient light information and adjusts a backlight intensity to an adjusted backlight intensity to make a backlight intensity of the panel substantially the same with the target display lightness. The second sensing unit senses an adjusted backlight information of the backlight module. The processing module estimates a color gain compensation value for the panel according to the adjusted backlight information and the real-time ambient light information and compensates the colors displayed on the panel when the panel displays an image according to the color gain compensation value.

  • Publication number: 20180167533
    Abstract: A color management system includes a host device and a display device. An operating system is installed in the host device and a first ICC profile is applied to the operating system. The display device communicates with the host device. The display device can be switched between a plurality of color modes. The display device stores a plurality of second ICC profiles, wherein each of the second ICC profiles corresponds to one of the color modes. When the display device is switched to an i-th color mode of the color modes, the host device determines whether the first ICC profile is identical to an i-th second ICC profile corresponding to the i-th color mode. When the host device determines that the first ICC profile is different from the i-th second ICC profile, the host device applies the i-th second ICC profile to the operating system.
