Abstract
本发明提供一种液晶显示面板,该液晶显示面板的TFT基板与CF基板分别具有可实现垂直光配向的第一与第二配向膜,经过紫外照光,使所述第一配向膜与第二配向膜的配向方向相互平行且方向相反,液晶分子以一定倾角呈近垂直配向;在不加电的暗态时,液晶分子近似垂直于TFT基板与CF基板表面排列,不产生相位差,漏光极低,暗态亮度很小因此对比度较高;施加显示电场以后,液晶分子会在平行于TFT基板与CF基板的平面内转动,因此具有IPS模式和FFS模式的广视角和高穿透率的特性。
Description
技术领域
本发明涉及显示技术领域,尤其涉及一种液晶显示面板。
背景技术
液晶显示面板的通常是由一彩膜基板(ColorFilterSubstrate,CFSubstrate)、一薄膜晶体管阵列基板(ThinFilmTransistorArraySubstrate,TFTArraySubstrate)以及一配置于两基板间的液晶层(LiquidCrystalLayer)所构成,其工作原理是通过在两片玻璃基板上施加驱动电压来控制液晶层的液晶分子的旋转,将背光模组的光线折射出来产生画面。按照液晶的取向方式不同,目前主流市场上的液晶显示面板可以分为以下几种类型:垂直配向(VerticalAlignment,VA)型、扭曲向列(TwistedNematic,TN)或超扭曲向列(SuperTwistedNematic,STN)型、平面转换(In-PlaneSwitching,IPS)型、及边缘场开关(FringeFieldSwitching,FFS)型。
对于VA模式而言,液晶显示器件主要由上、下两基板,以及夹设于两个基板之间的负性液晶分子组成。在上、下两基板的内侧均有透明导电层(氧化铟锡,ITO),从而可以形成垂直电场;在两层透明导电层之间嵌入的负性液晶,在没有垂直电场作用的情况下,液晶分子垂直于基板表面取向,当有垂直电场作用时,液晶分子会发生特定方向的取向,最终垂直于电场方向排列。
VA模式具有高对比度、高穿透率的画面显示优势,但由于VA模式采用垂直转动的液晶,液晶分子双折射率的差异比较大,导致其视角较差、大视角下的色偏问题比较严重,通常采用多畴VA技术,即将一个子像素划分成多个区域,并使每个区域中的液晶分子在施加电压后转动角度不一样,从而改善色偏问题。
随着技术的发展,出现了一种不需要使用配向膜的高分子稳定垂直配向模式(PolymerSustainedVerticalAlignment,PSVA),如图1所示,PSVA模式液晶显示面板包括第一基板100、与所述第一基板100相对设置的第二基板200、夹设于所述第一基板100与第二基板200之间的液晶层300、设于所述第一基板100上相互间隔的像素电极110、及设于所述第二基板200上靠近液晶层300一侧覆盖该第二基板200的公共电极210;所述液晶层300由多个液晶分子310和多个反应单体320构成。将第一基板100与第二基板200对组并填充液晶层300后,对公共电极210与像素电极110施加电压,使液晶分子310按照像素电极110的狭缝(slit)的方向倒伏;再使用紫外光(UltravioletRays,UV光)照射,使反应单体320反应形成附着于像素电极110与公共电极210表面的反应物凸起330,如图2所示,反应物凸起330用于固定液晶分子310形成一定方向的预倾角。如图3所示,当施加垂直电场作用时,液晶分子310发生特定方向的取向,最终垂直于电场方向排列。
PSVA模式具有快速相应和高对比度的特性,但由于液晶层中需加入反应单体参与配向过程,因此液晶的选用受到很大限制,易产生依赖性问题,对制程和材料都提出了很高的要求。
而IPS模式和FFS模式则具有广视角的特性,但对比度相对于VA模式较差。
发明内容
本发明的目的在于提供一种液晶显示面板,结合VA模式与IPS模式、FFS模式的优势,可以有效改善对比度,提高穿透率,并具有广视角的特性。
