Abstract
With an adaptive dimming technique, the number of gray levels can be increased by dimming the backlight luminance and also by interpolating the original signal. Gray-scale capability of the conventional 8bit LCD is not perfectly favorable to human eye perception. In this report, gray-scale capability of the conventional 8bit LCD was improved by introducing the adaptive dimming technique. It was found that 9-dimming step and 11-bit-equivalent resolution are necessary when the display is used in living room. The experimental results show the effectiveness of the proposed method.
