【摘要】：為了實(shí)現(xiàn)液晶顯示器的廣視角顯示,論文詳細(xì)闡述了一款54.6cm(21.5in)液晶顯示器的廣對比度視角液晶面板及廣亮度視角背光源的設(shè)計原理和方法。介紹了邊緣場開關(guān)模式液晶面板的設(shè)計方法及結(jié)構(gòu),從原理上闡釋了此液晶面板具有廣對比度視角的原因;介紹了背光源亮度視角的設(shè)計方法,通過對背光源中多組光學(xué)膜層架構(gòu)的測試和數(shù)據(jù)對比,得到了具有最廣亮度視角的膜層架構(gòu)。根據(jù)上述原理進(jìn)行實(shí)際模組樣品的制作并進(jìn)行實(shí)測,數(shù)據(jù)結(jié)果顯示此款液晶顯示器的對比度視角可達(dá)90°/90°/90°/90°,且在水平方向的1/2亮度視角可達(dá)60°,相應(yīng)的亮度視角均一性為1.20。通過對比其他同類產(chǎn)品的實(shí)測數(shù)據(jù),表明此款液晶顯示器無論在對比度視角還是亮度視角方面都遠(yuǎn)優(yōu)于同類產(chǎn)品。
[Abstract]:In order to realize the wide view display of liquid crystal display (LCD), the design principle and method of a 54.6cm (21.5in) liquid crystal display with wide contrast angle liquid crystal panel and wide brightness angle backlight are described in detail. This paper introduces the design method and structure of the edge field switch mode liquid crystal panel, explains the reason why the liquid crystal panel has wide contrast angle, and introduces the design method of the backlight luminance angle. Based on the test and data comparison of many groups of optical film structures in backlight, the film structure with the widest luminance view is obtained. According to the above principle, the actual module samples are made and measured. The results show that the contrast angle of the LCD can reach 90 擄/ 90 擄/ 90 擄/ 90 擄/ 90 擄, and the horizontal 1 / 2 brightness angle can reach 60 擄, and the uniformity of the corresponding luminance angle is 1.20 擄. By comparing the measured data of other similar products, it is shown that the LCD is far superior to the similar products in terms of contrast angle and brightness angle.
