Abstract:
1. An image-processing device for enhancing the luminance and the image quality of display panels, which is an RGBW color-system device for improving the optical efficiency of liquid-crystal displays, comprising: a color distribution calculating unit that calculates an original image-color data and calculates a ratio of the color data in any one of block B a control-variable generating unit that inputs the ratio so as to determine a value of a converting-control variable and a value of a backlight luminance-control variable; and a data-converting unit that inputs the converting-control variable, and the data-converting unit converts the original image-color data to a new image-color data; and a backlight luminance-control unit that inputs the backlight luminance-control variable, and a backlight luminance-control unit controls the backlight luminance of a display panel.
