摘要： An image display method of improving brightness of an output image in an image display device using a sequential driving method and a plurality of single-color light sources. The image display method includes extracting a white color component from the primary color image signals, calculating a period to display the white color component, converting the primary color image signals into shortened primary color image signals and a white color image signal based on the period to display the white color component, and driving the single-color light sources together during a period to display the white color image signal and sequentially driving the single-color light sources during a period to display the shortened primary color image signals. The brightness of output images is improved by displaying the white color image signal by simultaneously driving the single-color light sources based on a ratio of a lowest gradient to a highest gradient of the primary color signals.
