【摘要】：自从1925年约翰·洛奇·贝尔德在英国展示的电视装置开始,CRT显示技术主宰电视行业几十年之久。直到上世纪80年代,背投式显示技术的发展逐渐被认为将取代CRT技术,成为新型的显示技术。随着人们对更大、更薄、更清晰的显示要求不断被提出,平板显示将逐渐取代上述两种技术,平板显示中又以液晶显示最为突出。液晶显示作为当今应用最为广泛的显示技术之一,已经应用于生活的方方面面,不论是电脑、电视,还是车载导航等等,作为显示信息的主流载体,液晶一直居于至关重要的地位。尤其是手机互联网的兴起更是拓宽了液晶屏幕在手机方面的应用。但是随着社会的不断发展,越来越多的显示要求也显现出来,为了满足人们对于显示技术更高要求,高清显示、3D显示以及柔性显示便应运而生。胆甾相液晶柔性显示器件适合应用于不需要频繁更新画面的显示领域,比如说商品标牌、电子书,甚至是大型的电子广告牌等等。然而依据传统的液晶平板显示彩色化技术却不能完全实现柔性显示的彩色化的要求。主要反映在由于弯折后多层显示产生的反射对比度下降,产生的彩色并不能如实的反应真实场景；为了提高对比度等产生的大功耗问题；以及柔性彩色化显示的彩色失真等方面。这些亟待解决的问题,致使显示质量的差强人意,难以应用于实际。为了主要解决以上问题尤其是柔性彩色化显示中灰阶控制,即RGB单色反射率问题,以使产生的彩色稳定、逼真,使柔性显示可以更早地应用于实际,方便人们的生活,本论文主要阐述了各种外界条件对液晶反射率及反射波长的影响,为精确控制灰阶做准备。
[Abstract]:CRT display technology has dominated the television industry for decades since John Lodge Baird showed off television devices in Britain in 1925. Until the 1980s, the development of rear projection display technology was considered to replace CRT technology as a new display technology. As the demand for larger, thinner and clearer displays continues to be raised, flat panel displays will gradually replace these two technologies, with liquid crystal displays the most prominent in flat panel displays. As one of the most widely used display technologies, liquid crystal display (LCD) has been used in all aspects of life, whether computer, television, vehicle navigation and so on, as the mainstream carrier of display information. Liquid crystal has always been in a critical position. In particular, the rise of the mobile Internet has broadened the application of LCD screens in mobile phones. But with the continuous development of society, more and more display requirements also appear. In order to meet the higher demand for display technology, high-definition display, 3D display and flexible display came into being. Cholesteric liquid crystal flexible display devices are suitable for applications in display areas that do not need to be updated frequently, such as commodity signs, e-books, and even large electronic billboards. However, according to the traditional color technology of LCD flat panel display, the requirement of flexible display can not be fully realized. It is mainly reflected in the fact that the reflection contrast caused by the multi-layer display after bending is decreased, the color produced does not reflect the real scene truthfully, and in order to improve the contrast and so on, the large power consumption problem is produced. And flexible color display color distortion and so on. These problems need to be solved, resulting in poor display quality, difficult to be applied to practice. In order to mainly solve the above problems, especially the gray scale control in flexible color display, that is, RGB monochromatic reflectivity, so that the color produced can be stable and realistic, and flexible display can be applied to practice earlier and facilitate people's life. In this paper, the effects of various external conditions on the reflectivity and wavelength of liquid crystal are discussed in order to control the gray scale accurately.
