| Summary: | 碩士 === 國立交通大學 === 顯示科技研究所 === 98 === In conventional liquid crystal display, using CCFL backlight and color filters to generate a full color image. However, the optical throughput is lowered owning to the color filters. The backlight needs to give more power to generate a high luminance image. Accompany with the highly improved LED technology, the power and life time of LED can substitute the CCFL backlight. Because multi-color LEDs can mix color using red, green, and blue colors, the color filters can be removed. Therefore, a new liquid crystal display is proposed called Field Sequential Color LCD.
However, the color breakup happens when there is a relative motion during eye movement. We proposed four fields to combine a full color image. Let most information detail to display in specific field and rest of fields decrease its intensities. Then the color breakup is less observed. In order to implement on hardware with the concept, some simplification is needed. When finding the majority color of input image, we separate the image into three parts. Each part does the backlight convergence approach. Therefore, after image information is loaded into hardware, the adaptive backlight color is determined at the same time. Other three field images is re-calculated in the following. FSC LCD displays the image in a real-time process.
