Description

液晶显示面板及其应用的显示装置 技术领域
本发明涉及液晶显示技术领域，特别是涉及一种液晶显示面板及其应用的显示装置。
 背景技术
液晶显示器(Liquid Crystal Display，LCD)已被广泛应用于各种电子产品中，液晶显示器大部分为背光型液晶显示器，其是由液晶显示面板及背光模块(backlight module)所组成。液晶显示面板是由两片透明基板以及被封于基板之间的液晶所构成。特别是，由聚合物稳定配向(polymer－stabilized alignment，PSA)制程所制造而成的聚合物稳定垂直配向型(Polymer Stabilized Vertical Alignment, PSVA)液晶显示器，其可具有广视角、高开口率、高对比及制程简单等优点。
在PSVA液晶显示器中，两透明基板之间的液晶可被掺有反应型单体(reactive monomer)，其混合于液晶分子，其中，每一透明基板的表面涂布有聚酰亚胺(polyimide，PI)，其作为配向基材。接着，当施加电压及紫外光(UV)光照射于两透明基板时，反应型单体可与液晶分子发生相分离(phase separation)现象，而在透明基板的配向基材上形成聚合物。由于聚合物跟液晶分子之间的相互作用，液晶分子会沿着聚合分子的方向来排列，因此，透明基板之间的液晶分子可具有预倾角(pre-tile angle)。

在图中，结构相似的单元是以相同标号表示。
请参照图1，其显示依照本发明的第一实施例的液晶显示面板的局部剖面示意图。本实施例的显示装置可包括液晶显示面板100和背光模块(未绘示)。液晶显示面板100相对于背光模块来设置，此背光模块可为侧光式(side Lighting)背光模块或直下式入光(Bottom Lighting)背光模块，以提供背光至液晶显示面板100。
如图1所示，本实施的液晶显示面板100可包括第一基板110、第二基板120、液晶层130、第一偏光片140及第二偏光片150。第一基板110和第二基板120的基板材料可为玻璃基板或可挠性塑料基板，在本实施例中，第一基板110可例如为具有彩色滤光片(Color Filter，CF)的玻璃基板或其它材质的基板，而第二基板120可例如为具有薄膜晶体管(Thin Film Transistor，TFT) 矩阵的玻璃基板或其它材质的基板。值得注意的是，在一些实施例中，彩色滤光片和TFT矩阵亦可配置在同一基板上。
如图1所示，液晶层130是形成于第一基板110与第二基板120之间，液晶层130并包括反应型单体和液晶分子，反应型单体优选是感光性单体，其混合于液晶分子中。第一偏光片140是设置第一基板110的一侧，并相对于液晶层130(亦即为第一基板110的出光侧)，第二偏光片150是设置第二基板120的一侧，并相对于液晶层130(亦即为第二基板120的入光侧)。
如图1所示，在本实施例中，第一基板110可包括第一电极111、第一配向层112、第一聚合物配向层113，第一配向层112及第一聚合物配向层113是依序形成于第一电极111上。第二基板120可包括第二电极121、第二配向层122、第二聚合物配向层123，第二配向层122及第二聚合物配向层123是依序形成于第二电极121上。第一电极111和第二电极121优选是以透光导电材料所制成，例如：ITO、IZO、AZO、GZO、TCO或ZnO，第一电极111和第二电极121可施加电压于液晶层130的液晶分子。在本实施例中，第一电极111例如为共同电极，第二电极121例如为像素电极。且第二电极121可具有多个区域(未绘示)，而每一区域所被施加的电压可为相同或不相同。配向层112、122及聚合物配向层113、123可具有一配向方向，用来决定液晶层130的液晶分子的配向，且配向层112、122及聚合物配向层113、123可具有一预倾角，此预倾角是小于90度，优选是小于60度。配向层112、122优选是利用溅射技术来形成介电材料于基板110、120上，配向层112、122的材料优选是介电无机材料，例如二氧化硅(SiO2)。聚合物配向层113、123是由反应型单体101所聚合而成，其形成于配向层112、122上。
请参照图2和图3，图2显示依照本发明的第一实施例的液晶显示面板的像素区域的示意图，图3显示依照本发明的第一实施例的液晶显示面板的子像素区域的示意图。第二基板120包括多条信号线(未显示)，其例如为栅极线及数据线，且相互垂直交错，而呈矩阵式排列，因而形成多个像素区域101。在每一像素区域101中，第二电极121具有一像素电极图案，用于形成多显示域配向(multi－domain alignment)。在本实施例中，每一像素区域101内的第二电极121包括主像素电极图案124及多个条状电极单元125，主像素电极图案124可呈十字形图案，因而每一像素区域101可被主像素电极图案124分为四个子像素区域102。在每一子像素区域102中，条状电极单元125是由主像素电极图案124来倾斜地延伸出，并相互平行排列。其中，条状电极单元125具有不同的延伸角度变化，亦即单一条状电极单元125与水平主像素电极图案124(或水平方向)之间可具有多个角度θ1、θ2、θ3、θ4。优选地，条状电极单元125的延伸角度变化范围是在40度与45度之间。
在本实施例中，单一条状电极单元125可由多个直线条状图案所组成，以形成不同的延伸角度变化。在另一实施例中，此条状电极单元125亦可为曲线条状图案，而具有连续的延伸角度变化。
请参照图4，其显示依照本发明的第一实施例的像素的电压(V)-透过率(T)曲线图。在图4中，线段103表示当条状电极单元125的延伸角度(亦即条状电极单元125与水平方向之间的角度)为45度时像素的V-T关系，线段104表示当条状电极单元125的延伸角度为40度时像素的V-T关系。如图4所示，当条状电极单元125具有不同的延伸角度时，像素的V-T表现亦不同。因此，通过调整第二电极121的条状电极单元125的延伸角度，可调整像素的V-T，进而可调整液晶显示面板100的色偏表现，改善液晶显示面板100的色偏问题。
因此，由于本实施例的液晶显示面板100的色偏问题可通过条状电极单元125的延伸角度变化调整来改善，因而可无需额外的控制组件(例如时序控制器)来进行色散补偿，以减少液晶显示面板100的设计成本。
请参照图5，其显示依照本发明的第二实施例的液晶显示面板的像素区域的示意图。以下仅就本实施例与第一实施例间的相异处进行说明，而其相似处则在此不再赘述。相较于第一实施例，第二实施例的每一像素区域201内的第二电极221包括主像素电极图案224及多个条状电极单元225，条状电极单元225可具有不同的延伸角度变化，以调整液晶显示面板的色偏表现。再者，这些条状电极单元225之间更可具有至少二个不同的排列间距(pitch)P1、P2，第一排列间距P1(例如7μm)和第二排列间距P2(例如6μm)可交替地形成于条状电极单元225之间，以进一步改善液晶显示面板的色偏问题，而可达到广视角低色偏之效果。
请参照图6，其显示依照本发明的第三实施例的液晶显示面板的像素区域的示意图。以下仅就本实施例与第一实施例间的相异处进行说明，而其相似处则在此不再赘述。相较于第一实施例，第三实施例的每一像素区域301内的第二电极321包括主像素电极图案324及多个条状电极单元325，条状电极单元325可具有不同的延伸角度变化，以调整液晶显示面板的色偏表现。再者，这些条状电极单元325之间更可具有三个或三个以上不同的排列间距P1、P2、P3、P4，其可依序地形成于每一子像素区域302内的条状电极单元325之间，用于调整液晶显示面板的色偏表现，而可改善液晶显示面板的色偏问题。
由上述可知，本发明的液晶显示面板及其应用的显示装置可通过调整像素电极图案中的条状电极单元的延伸角度变化，而大幅地改善液晶显示面板的色偏问题，确保显示装置的显示质量。且液晶显示面板可无需额外的控制组件来进行色散补偿，以减少显示器的设计成本。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
