本申请涉及显示技术领域，尤其是涉及一种彩膜基板。
 背景技术
彩膜基板包括显示区和围绕显示区的边框区，在显示画面时，显示区内的相邻像素之间的发光发生混色，达到显示效果。
但是显示区内靠近边框区的像素一侧为黑色矩阵，在进行混色时仅能与一个像素的发光和纯黑色进行混色，而显示区内未靠近边框区的像素会与两个像素的发光进行混色，即显示区内不同位置的像素会显示不同的混色效果。
所以，现有的彩膜基板存在显示区中与非显示区接触的区域内的像素与显示区中未与非显示区接触的区域内的像素具备不同混色效果的技术问题。

 附图说明
为了更清楚地说明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单介绍，显而易见地，下面描述中的附图仅仅是申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为现有技术彩膜基板结构示意图；
图2为本申请实施例中彩膜基板结构示意图。
 本发明的实施方式
以下各实施例的说明是参考附加的图示，用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本申请，而非用以限制本申请。在图中，结构相似的单元是用以相同标号表示。
本申请针对现有的彩膜基板存在显示区内不同位置像素具备不同混色效果的技术问题，本申请实施例可以解决该问题。
如图1所示，现有彩膜基板包括非显示区11和显示区12，在显示区12内像素按红色子像素123、绿色子像素122和蓝色子像素121阵列排布，每三个子像素组成一个像素，在显示区12最边缘两侧分别为红色子像素123以及蓝色子像素121，在非显示区11设有靠近显示区12的黑色矩阵13。
现有液晶显示器在显示纯红画面时，处于中间部分的像素会与相邻像素混色，而最边缘的像素一边为黑色矩阵，则最边缘的像素与相邻的像素以及黑色矩阵混色将使显示区边缘显示偏黄；在显示纯蓝画面时，与显示纯红画面相同，会造成显示区边缘显示发白；而显示灰阶画面时，中间区域显示白色，而最边缘的像素一侧与黑色矩阵混色，会在显示区边缘显示红蓝线。
综上所述，现有的彩膜基板存在显示区中与非显示区接触的区域内的像素与显示区中未与非显示区接触的区域内的像素具备不同混色效果的技术问题，针对该问题，本申请提出以下实施例。
在本申请实施例中，开口率为开口面积与显示区总面积之比，例如，图2中第二区域像素开口率即为第二区域像素开口面积比显示区总面积，其余开口率与第二区域像素开口率定义相同，在下述实施例不再重复叙述。
如图2所示，本申请实施例提供一种彩膜基板，该彩膜基板包括显示区和非显示区，在像素的排列方向上，所述显示区包括与非显示区接触的第一区域22，以及未与非显示区接触的第二区域24，在非显示区靠近显示区设有黑色矩阵21，在各像素之间设有黑色矩阵21，通过改变黑色矩阵的面积大小，使第一区域内像素开口率小于第二区域内像素开口率。
在本申请实施例中，在保持显示区总面积不变的情况下，通过增大显示区黑色矩阵的面积将第一区域像素开口率降低，使得第一区域像素的发光与黑色矩阵的纯黑色混色后显示的面积减小，从而使得显示区不同区域呈现近似相同甚至相同的混色效果，缓解了现有的彩膜基板存在显示区中与非显示区接触的区域内的像素与显示区中未与非显示区接触的区域内的像素具备不同混色效果的技术问题。
如图2所示，本申请实施例中第一区域包括与左侧非显示区接触的左侧区域，以及与右侧非显示区接触的右侧区域，通过将显示区两侧的像素开口率降低，使得彩膜基板在显示纯红画面或者纯蓝画面时都可以在显示区不同区域呈现近似相同甚至相同的混色效果；而为了使显示区不同位置呈现相同的混色效果，本申请提供以下实施例。
如图2所示，本申请实施例提供一种彩膜基板，在第一区域22与第二区域24之间设置了第三区域23，控制黑色矩阵21，使第三区域像素开口率大于第一区域像素开口率，且第三区域像素开口率小于第二区域像素开口率；通过在第一区域与第二区域之间设置第三区域，且控制第三区域像素开口率处于第一区域像素开口率与第二区域像素开口率之间，则第三区域能够对混色效果起到缓冲作用，使得显示区不同区域呈现相同的混色效果。
在本申请实施例中，第一区域可为一列像素或者多列像素，第三区域可为一列像素或者多列像素，多列像素开口率沿远离非显示区的方向递增，将起到不同程度的缓冲作用，使得显示区不同区域呈现更加相似甚至相同的混色效果。
在本申请实施例中，每列像素中不同列子像素开口率可以递增，而这将会造成在检测两列及两列以上像素时出现亮度显示不均的问题，针对该问题，本申请提供以下实施例。
如图2所示，本申请实施例将像素划分为阵列排布的红色子像素201、绿色子像素202和蓝色子像素203，通过控制黑色矩阵21的面积，随机降低每个子像素的开口率，但是控制每列像素中每列子像素的开口率相同，且每行子像素的开口面积之和相同，则可以使得在对两列及两列以上像素进行画面检测时，像素的发光呈现均匀的亮度。
在本申请实施例中，将第一区域内像素的所有子像素开口率设置为小于第三区域内像素的对应子像素开口率，将第三区域内像素的所有子像素开口率设置为小于第二区域内像素的对应子像素开口率，使得对于同一种子像素，其子像素开口率沿远离非显示区的方向递增，可以在减小子像素的发光与黑色矩阵的纯黑色混色显示的面积的同时，使混色显示的面积依此增大，从而在显示区不同区域显示出更加相似甚至相同的混色效果。
在一种实施例中，使第一区域内像素的各行子像素开口率相同，即各行红色子像素开口率加蓝色子像素开口率加绿色子像素开口率的和相等，但不限制每个子像素的开口率，使每个子像素的开口率随机设置。
在本申请实施例中，考虑到像素开口面积不能太小，且在形成缓冲区域时，显示区不同位置呈现的混色效果更加相似；假设第二区域内的像素开口率为s，则第一区域内的像素开口率为ns，进一步限定第三区域内的像素开口率为（n+1）s/2，其中限定n为0.6至0.8时，将会使显示区不同区域呈现更相似甚至相同的混色效果。
本申请实施例提供一种液晶显示装置，该液晶显示装置包括阵列基板，本申请实施例提供的彩膜基板，以及配置于两基板之间的液晶层，在阵列基板上设置薄膜晶体管阵列，阵列基板用于旋转液晶，控制像素显示，彩膜基板用于调节像素颜色，使其显示出不同的画面；通过设置彩膜基板第一区域的像素开口率小于彩膜基板第二区域的像素开口率，在液晶显示装置显示纯色画面时，通过彩膜基板像素的光线在第一区域与纯黑色混色显示的面积较小，使得液晶显示装置边缘与中间部分显示的画面一致，避免液晶显示装置在边缘与中间部分出现不同显示效果的问题，使液晶显示装置显示相同的画面。
根据上述实施例可知：
本申请实施例提供一种彩膜基板，该彩膜基板包括非显示区和显示区，在像素排列方向上，所述显示区包括与非显示区接触的第一区域，以及未与非显示区接触的第二区域，所述第一区域内像素开口率小于所述第二区域内像素开口率；通过将靠近非显示区的第一区域的像素开口率减小，使第一区域像素的发光与纯黑色混色显示的区域变小，从而使得显示区呈现相同的混色效果；进一步的，通过将显示区两侧将像素开口率减小，使得针对不同的画面，显示区不同区域均能呈现相同的混色效果；进一步的，通过在第一区域与第二区域中间设置第三区域，并设置所述第三区域的像素开口率大于第一区域像素开口率，且第三区域的像素开口率小于第二区域像素开口率，使得在显示时，第三区域将起到缓冲效果，使显示区不同区域的混色效果更加一致；通过设置每列像素中每列子像素开口率相等，使得在检测两列或者两列以上像素时，不会出现显示的亮度不均的问题；进一步的，通过将上述彩膜基板设置在显示装置上，使得显示装置在显示画面时呈现一致的画面，改善画面效果。
综上所述，虽然本申请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申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
