为解决上述技术问题,本发明采用的再一个技术方案是:提供一种液晶显示器,包括彩膜基板,该彩膜基板包括基板本体和设置于基板本体上的色阻层,色阻层包括依次重复排列的色阻,色阻层包括第一显示区域和位于第一显示区域外围的第二显示区域,其中,位于第二显示区域的色阻的厚度高于位于第一显示区域的色阻的厚度,以使对应于第二显示区域的显示面板的穿透率小于对应于第一显示区域的显示面板的穿透率。
其中,位于第二显示区域的色阻的厚度与位于第一显示区域的色阻的厚度的关系为:
其中,K表示材料的吸收系数,Ls表示第二显示区域的色阻的厚度,Lm表示第一显示区域的色阻的厚度。
其中,第一显示区域呈矩形设置,两个第二显示区域沿第一方向设置于第一显示区域的两侧。

图2是图1彩膜基板中色阻层的平面示意图;
图3是本发明第二实施例的彩膜基板的截面示意图;
图4是图3彩膜基板中色阻层的平面示意图。
在说明书及权利要求书当中使用了某些词汇来指称特定的组件,所属领域中的技术人员应可理解,制造商可能会用不同的名词来称呼同样的组件。本说明书及权利要求书并不以名称的差异来作为区分组件的方式,而是以组件在功能上的差异来作为区分的基准。下面结合附图和实施例对本发明进行详细说明。
图1是本发明第一实施例的彩膜基板的截面示意图。如图1所示,彩膜基板包括:基板本体11和设置于基板本体11的色阻层12,其中,色阻层12包括依次重复排列的RGB色阻。
请一并参考图2,图2是图1彩膜基板中色阻层的平面示意图。色阻层12包括第一显示区域121和位于第一显示区域121外围的第二显示区域122。
具体来说,第一显示区域121呈矩形设置,两个第二显示区域122沿第一方向X分别设置于第一显示区域121的两侧。在第一方向X上,每个第二显示区域122设置的宽度W1为显示面板设置的宽度的5%~10%。其中,在第一方向
X上,两个第二显示区域122设置的宽度可以相同、也可以不相同。
IPS液晶显示面板的穿透率的计算公式如下所示:
L1(λ)=T(λ)·L0(λ)
T(λ)=T下偏对各向同性光(λ)·TArray玻璃(λ)·η开口率·TLC(λ)·ηLC(λ)·TCF玻璃(λ)·T上偏对偏振光(λ)
=TCF玻璃(λ)·χ
其中,L1(λ)表示面板出射亮度,L0(λ)表示背光亮度,T(λ)表示整体穿透率,χ表示其他影响因素,THKRGB表示RGB色阻厚度。
从上述公式可知,随着RGB色阻厚度THKRGB的增加,彩膜基板的穿透率TCF玻璃(λ)减少,从而使得液晶面板中厚度增加的RGB色阻对应的区域的整体穿透率T(λ)减少。
另外,IPS液晶显示面板对应不同材质不同厚度的光吸收公式为:
I=I0*e-Kl
其中,I为出射光的强度,I0为入射光的强度,K为材料的吸收系数,L为色阻的厚度。
由于位于第二显示区域的穿透率低于位于第一显示区域的穿透率,由此可得到:
其中,Is表示第二显示区域的亮度,Im表示第一显示区域的亮度,Ls表示第二显示区域的色阻的厚度,Lm表示第一显示区域的色阻的厚度。
从而得出位于第二显示区域的色阻的厚度Ls与位于第一显示区域的色阻的厚度Lm的关系为:
因此,在本发明第一实施例中,设置位于第二显示区域122的色阻的厚度Ls高于位于第一显示区域121的色阻的厚度Lm,同时设置位于第二显示区域122的色阻的厚度Ls与位于第一显示区域121的色阻的厚度Lm满足
的关系,以使对应于第二显示区域122的显示面板的穿透率小于对应于第一显示区域的显示面板121的穿透率,从而可以改善显示面板边缘因为液晶盒厚度的差异而造成周边暗态不均的问题,进而提高显示面板亮度的均一性。
在本发明第一实施例中,位于第一显示区域121的RGB色阻具有相同的厚度,位于第二显示区域122的RGB色阻具有相同的厚度,位于第二显示区域122的RGB色阻的厚度高于位于第一显示区域121的RGB色阻的厚度。
其中,位于第二显示区域122的RGB色阻高于第一显示区域121的RGB色阻的厚度部分可以通过涂布工艺(coating)或者喷涂工艺(injek)进行增加。具体来说,首先对第一显示区域121进行遮罩(mask)处理,随后采用刷子刷或者喷头喷的方式,通过控制刷子或喷头的工作速度以及原料滴的用量定量增加第二显示区域122的RGB色阻的厚度。
其中,液晶显示面板中同一像素对应三种不同颜色的色阻,也即一个像素对应红、绿、蓝三种颜色的色阻(RGB色阻),对应于同一像素的RGB色阻可以分别位于第一显示区域121和第二显示区域122。例如,对应于同一像素的R色阻和G色阻位于第一显示区域121,B色阻位于第二显示区域122;对应于同一像素的R色阻位于第一显示区域121,G和B色阻位于第二显示区域122;对应于同一像素的R色阻和G色阻的一部分位于第一显示区域121,G色阻的剩下部分和B色阻位于第二显示区域122等等。优选地,对应于同一像素的RGB色阻可以同时位于第一显示区域121或者同时位于第二显示区域122。
图3是本发明第二实施例的彩膜基板的截面示意图。如图3所示,彩膜基板包括:基板本体21和设置于基板本体21的色阻层22,其中,色阻层22包括依次重复排列的RGB色阻。
请一并参考图4,图4是图3彩膜基板中色阻层的平面示意图。色阻层22包括第一显示区域221和位于第一显示区域221外围的第二显示区域222。
具体来说,第一显示区域221呈矩形设置,两个第二显示区域222沿第一
方向X设置于第一显示区域221的两侧,两个第二显示区域222沿垂直于第一方向X的第二方向Y设置于第一显示区域221的两侧。
在第一方向X上,每个第二显示区域222设置的宽度W1为显示面板设置的宽度的5%~10%,在第二方向Y上,每个第二显示区域222设置的宽度W2为显示面板设置的宽度的5%~10%。其中,在第一方向X上,两个第二显示区域222设置的宽度可以相同也可以不相同,在第二方向Y上,两个第二显示区域222设置的宽度可以相同也可以不相同。
在本发明第二实施例中,位于第二显示区域222的色阻的厚度高于位于第一显示区域221的色阻的厚度,位于第二显示区域122的色阻的厚度Ls与位于第一显示区域121的色阻的厚度Lm满足的关系,以使对应于第二显示区域222的显示面板的穿透率小于对应于第一显示区域221的显示面板的穿透率。
具体来说,位于第一显示区域221的RGB色阻具有相同的厚度,位于第二显示区域222的RGB色阻具有不同的厚度。其中,位于第二显示区域222的RGB色阻的厚度在朝向第一显示区域221的边缘位置逐渐变薄。优选地,位于第二显示区域122的RGB色阻的厚度在朝向第一显示区域121的边缘位置呈弧形过渡。
其中,位于第二显示区域122的RGB色阻高于第一显示区域121的RGB色阻的厚度部分可以通过涂布工艺(coating)或者喷涂(injek)工艺进行增加。
其中,对应于同一像素的RGB色阻可以分别位于第一显示区域121和第二显示区域122,也可以同时位于第一显示区域121或者同时位于第二显示区域122。
本发明进一步提供一种液晶显示器,包括了上述彩膜基板。
本发明的有益效果是:本发明的彩膜基板通过设置位于第二显示区域的色阻的厚度高于位于第一显示区域的色阻的厚度,其中,第二显示区域位于第一显示区域的外围,以使对应于第二显示区域的显示面板的穿透率小于对应于第
一显示区域的显示面板的穿透率,从而改善显示面板边缘因为液晶盒厚度的差异而造成周边暗态不均的问题,进而提高显示面板亮度的均一性。
以上所述仅为本发明的实施方式,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
