Abstract
A liquid crystal display (LCD) device includes a pixel array including a plurality of pixels configured to display an image. The plurality of pixels respectively include a first subpixel configured to display first color image data, and a second subpixel configured to display second and third color image data. The LCD device may further include a backlight configured to emit the first, second, and/or third colors of light, and a backlight controller. The backlight controller may be configured to activate the backlight to emit the first and second colors of light at a same time to generate a first image component including a combination of the first color image data and the 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 the third color image data. The pixel array may be configured to display the first and second image components to provide a single image frame. Related devices and methods of operation are also discussed.
