Abstract
A liquid crystal display (LCD) device includes a backlight configured to emit first, second, and/or third colors of light, and a backlight controller. The backlight controller is configured to activate the backlight to simultaneously emit the first and second colors of light to generate a first image component including a combination of first color image data and second color image data, and to separately emit the third color of light at a different time than the first and second colors of light to generate a second image component including third color image data. The LCD device is configured to display the first and second image components to provide a single image frame. Related devices and methods of operation are also discussed.
