<p><P>PROBLEM TO BE SOLVED: To provide an LED-based field-sequential color display that can reliably produce light with the desired luminance and chrominance characteristics. <P>SOLUTION: A field-sequential color light system 100 includes multiple color LEDs 110 and a spectral feedback control system 106 that is configured to drive the color LEDs to produce light used for backlighting, to detect the light from the color LEDs, and to adjust color-sequential drive signals in response to the light detection. Detecting the emitted light by a color sensor 120 and adjusting the color-sequential drive signals output from a driver 124 in response thereto allows luminance and chrominance characteristics of the emitted light from the field-sequential color light system to be maintained at desired levels as the performance of the LEDs change over time. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
