【摘要】：自從1925年約翰·洛奇·貝爾德在英國展示的電視裝置開始,CRT顯示技術(shù)主宰電視行業(yè)幾十年之久。直到上世紀(jì)80年代,背投式顯示技術(shù)的發(fā)展逐漸被認(rèn)為將取代CRT技術(shù),成為新型的顯示技術(shù)。隨著人們對(duì)更大、更薄、更清晰的顯示要求不斷被提出,平板顯示將逐漸取代上述兩種技術(shù),平板顯示中又以液晶顯示最為突出。液晶顯示作為當(dāng)今應(yīng)用最為廣泛的顯示技術(shù)之一,已經(jīng)應(yīng)用于生活的方方面面,不論是電腦、電視,還是車載導(dǎo)航等等,作為顯示信息的主流載體,液晶一直居于至關(guān)重要的地位。尤其是手機(jī)互聯(lián)網(wǎng)的興起更是拓寬了液晶屏幕在手機(jī)方面的應(yīng)用。但是隨著社會(huì)的不斷發(fā)展,越來越多的顯示要求也顯現(xiàn)出來,為了滿足人們對(duì)于顯示技術(shù)更高要求,高清顯示、3D顯示以及柔性顯示便應(yīng)運(yùn)而生。膽甾相液晶柔性顯示器件適合應(yīng)用于不需要頻繁更新畫面的顯示領(lǐng)域,比如說商品標(biāo)牌、電子書,甚至是大型的電子廣告牌等等。然而依據(jù)傳統(tǒng)的液晶平板顯示彩色化技術(shù)卻不能完全實(shí)現(xiàn)柔性顯示的彩色化的要求。主要反映在由于彎折后多層顯示產(chǎn)生的反射對(duì)比度下降,產(chǎn)生的彩色并不能如實(shí)的反應(yīng)真實(shí)場景；為了提高對(duì)比度等產(chǎn)生的大功耗問題；以及柔性彩色化顯示的彩色失真等方面。這些亟待解決的問題,致使顯示質(zhì)量的差強(qiáng)人意,難以應(yīng)用于實(shí)際。為了主要解決以上問題尤其是柔性彩色化顯示中灰階控制,即RGB單色反射率問題,以使產(chǎn)生的彩色穩(wěn)定、逼真,使柔性顯示可以更早地應(yīng)用于實(shí)際,方便人們的生活,本論文主要闡述了各種外界條件對(duì)液晶反射率及反射波長的影響,為精確控制灰階做準(zhǔn)備。
[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.
