摘要(中) 近年來LCD顯示器不斷發展,廠商積極的投入資源,LCD顯示器的設計作法也投入新的思維,顯示器的產品一直走向更清晰的影像,更逼真的色彩。我們瀏覽探索了不同的新技術,進一步設計了一個可以調變背光顏色的LCD顯示器光學系統,在這個新設計當中,我們儘量維持現有的顯示器架構,僅做少部份的必要改變,以相容於既有的生產程序。
在研究過程中,基於量測所得的光譜做分析發現,彩色濾光片三主色的穿透率光譜會有很大的重疊區域,這是造成顏色飽和度不佳的主要原因,而且其中藍色與綠色的穿透率光譜會有較大的重疊區域。所以,我們以時序分工(time sharing)的設計,提出一個新穎的分色作法,以不同的主色分色和背光光源的同時控制,將彩色濾光片的缺點避開。我們認為這樣是可行性高的設計。將此設計實作完成之後,以實驗量測加以印證,有效地得到一個色域增大百分之二十的廣色域混色模式。
摘要(英) In recent years, the intensive development of liquid-crystal displays (LCDs) has been creating much clearer images and much more vivid colors showing on the displays. As reviewing several new technologies, one novel design on the backlight modules of color LCD displays is proposed in this work to enhance the color qualities of the images but still not substantially change too much of the existing configuration of the LCD displays.
Based on measurements from the spectral analysis, we found the fact that the mismatch between the transmittance spectra of the color filters and the primary color lights from the backlight modules is the main excuse for poor color saturation. Most of all, the transmittance spectra of the blue color filters and the green color filters have a big overlap band such that the blue light from the backlight module can leak via the green color filters and the green light via the blue ones. Applying the time sharing concept, one novel categorizing method for color sequential multiplexing is proposed to effectively enhance the color gamut of the LCD displays. In our practical implementation, the color gamut has been greatly increased by almost 20%.
