System and method for providing a wide aspect ratio flat panel display monitor independent white-balance adjustment and gamma correction capabilities

A high-precision flat panel monitor comprising:

• an image data input for coupling to said host computer to receive image data;
• a liquid crystal display screen for displaying said image data, said liquid crystal display screen including:
• a first white light source of a first color temperature;
• a second white light source of a second color temperature different from said first color temperature, said first and second white light sources positioned to illuminate said liquid crystal display screen with light having a net color temperature that is dependent on an intensity of said first white light source and an intensity of said second white light source wherein said first and said second white light sources alter said net color temperature of said light, within a predetermined color temperature range, by controlling said intensity of said first white light source and said intensity of said second white light source;
• and
• a white-balance adjustment control input for coupling to said host computer to receive a white-balance adjustment control signal, said white-balance adjustment control signal for adjusting said intensity of said first white light source and said intensity of said second white light source to adjust said net color temperature of said liquid crystal display screen, wherein grayscale resolution of said liquid crystal display screen is substantially unaffected by adjustment of said net color temperature.

A computer-usable medium having computer-readable program code embodied therein for causing a computer to perform a method of color-calibrating a flat panel display, said flat panel display having a liquid crystal display screen configured to be illuminated by a first white light source with a first color temperature and a second white light source with a second color temperature, said method comprising the steps of:

• displaying on said flat panel display an image having a predefined white-balance value;
• determining color characteristics of said flat panel display, said color characteristics being provided by a light-sensing device coupled to said flat panel display, said color characteristics further including white-balance data and gamma values of said flat panel display;
• comparing said white-balance data to a predetermined reference white-balance value;
• and
• transmitting a white-balance adjustment control signal to said flat panel display to adjust a color temperature of said flat panel display by adjusting a first intensity level of said first light source and a second intensity level of said second light source without substantially affecting a grayscale resolution of the display, wherein white-balance adjustment control signal is generated according to differences between said white-balance data and said predetermined reference white-balance value.
