Description

像素结构、彩膜基板及显示面板 技术领域
本发明涉及显示技术领域，尤其涉及一种像素结构、彩膜基板及显示面板。
背景技术
FHD(Full High Definition，全高清)面板的像素为1920×1080，而每个像素是由红色(R)子像素、绿色(G)子像素和蓝色(B)子像素所组成；UHD(Ultra High Definition，超高清)面板的分辨率为3840×2160，UHD的分辨率是FHD面板的4倍。但是，高分辨率的像素会造成所述面板透光率的下降，从而降低显示画面的亮度。
现有技术中通过在R、G、B三种子像素的基础上增加白色(W)的子像素，即RGBW的像素结构，以通过所述白色子像素提高面板的透光率。但是，现有技术中的所述RGBW的像素结构中R、G、B、W四中子像素并排设置，使得面板的分辨率降低。例如，UHD面板水平像素数为3840，RGB像素结构下的水平子像素数为11520；当所述UHD面板为RGBW像素结构时，因为是R、G、B、W子像素4个子像素来构成1个像素，因此水平像素数仅剩下2880，而RGBW面板的垂直像素数仍是2160，与RGB排列的UHD面板相同，从而使得所述UHD面板的分辨率降低。进一步的，现有技术中，为保证所述UHD面板的分辨率不发生变化，将所述白色(W)子像素设于一个像素中的所述R、G、B三个子像素中至少一个子像素上，以保证在具有足够的画面亮度的情况下不改变面板的分辨率。但是，现有技术中，所述白色子像素在所述子像素的区域位置是随机的，且所述白色子像素一般均集中设于所述子像素的一个区域，从而会造成所述面板全视角透过率不均的现象，使得所述面板的出光不均匀。请参阅图1，现有技术一实施例中，所述子像素为四畴结构，所述白色子像素20内嵌于所述子像素内，且所述白色子像素20均集中设于所述子像素的一个畴结构内。进一步参阅图6(a)述现有技术实施例的所述子像素的全视角透过率模拟分析可知，所述白色子像素20嵌设于所述子像素的位置透过率会显著增加，所述白色子像素20集中设于所述子像素的一个畴结构内时，所述白 色子像素20所在的位置出现了严重的亮度偏移现象，使得所述子像素的全视角透过率不均，从而使得包含多个所述子像素的像素结构的透过率不均，进而造成所述面板的出光不均匀。

所述白色子像素20内嵌于所述三个子像素中至少一个子像素内。本实施例中，所述白色子像素20仅内嵌于所述蓝色子像素13内。可以理解的是，每个像素单元100中的所述白色子像素20均可内嵌于所述红色子像素11、绿色子像素12、所述蓝色子像素13中任意一个或两个或三个内。例如，所述白色子像素20可以内嵌于红色子像素11内；或者内嵌于蓝色子像素13及红色子像素11内；或者同时内嵌于红色子像素11绿色子像素12及蓝色子像素13内。所述白色子像素20分为多个大小相同的白色子像素区域21，一个所述白色子像素区域21位于一个所述畴区域14内。从而使得所述白色子像素20分散于其所在的子像素的各个畴区域内，且每个畴区域内的所述白色子像素区域21大小相同，进而保证所述子像素各个位置的出光均匀，进一步提高所述像素结构的透过率的均一性。进一步的，相邻两个所述白色子像素区域在其所在畴区域内的位置对称，使得每个所述畴区域14内的出光一致，进一步增加所述子 像素各个位置的出光均匀。在一实施例中，如图2所示，任意一个所述白色子像素区域21在其所在畴区域14内的位置与其它的所述白色子像素区域21位于其所在畴区域14内的位置相同。
本实施例中，每个所述像素单元100中的所述红色子像素11、绿色子像素12、所述蓝色子像素13均为四畴结构，即所述红色子像素11、绿色子像素12、所述蓝色子像素13均包括四个阵列排布的畴区域14，所述白色子像素20分为四个白色子像素区域21。每个所述白色子像素区域21均与一个所述蓝色子像素13的畴区域14对应并均位于其所在的所述畴区域14的中心位置。且所述白色子像素区域21相互之间不连接。
请参阅图3，本发明另一实施例中，其与图2所述的实施例中的所述子像素的区别在于，每个所述白色子像素区域21均位于其所在子像素的所述畴区域14的边缘并互不连接。且四个所述白色子像素区域21围成一长方形的图形，且所述图形的对称中心与所述白色子像素20所在的所述子像素的对称中心重合。可以理解的是，所述白色子像素区域21还可以位于所述所述畴区域14的边缘的任意位置。
请参阅图4，本发明另一实施例中，其与图3所述的实施例中的所述子像素的区别在于，每个所述白色子像素区域21均位于每个所述畴区域14的边缘并相互连接成一体，且四个所述白色子像素区域21的对称中心与所述白色子像素21所在的所述子像素的对称中心重合。本实施例中，所述白色子像素区域21有四个，四个所述白色子像素区域21分别位于四个所述畴区域的一个角上，且四个所述白色子像素区域21相互连接成一个整体，四个所述白色子像素区域21连接形成的所述整体位于所述子像素的中心位置。
请参阅图5，本发明另一实施例中，其与图4所述的实施例的所述子像素的区别在于，四个所述白色子像素区域21分别位于四个所述畴区域的一条边上，且四个所述白色子像素区域21相互连接成一个整体，四个所述白色子像素区域21连接形成的所述整体位于所述子像素的中部位置，并将所述子像素分成上部、中部及下部三个部分。
请参阅图6(b)-6(e)，分别为本发明图2-5所述实施例的全视角透过率模拟图，通过与图6(a)中所示现有技术中的一实施例的全视角透过率模拟图进行对 比可知，本发明的所述子像素各个位置的光线透过率较现有技术中所述子像素的光线透过率均一性高，不会出现严重的亮度偏移现象。
请参阅图7，可以理解的是，在其它的实施例中，当所述红色子像素11、绿色子像素12、所述蓝色子像素13可以均为八畴结构，所述八畴结构包括八个畴区域14，且八个畴区域14分为两组，每组所述畴区域14为与所述四畴结构相同的结构，即所述八畴结构相当于包括两个相连的四畴结构。所述白色子像素20均匀分布于所述子像素的两个四畴结构中任意一个所述四畴结构，且所述白色子像素20均匀分布于所述四畴结构的每个所述畴区域14内，即所述白色子像素20可以包括四个形状结构相同的白色子像素区域21，所述白色子像素区域21与所述白色子像素分布的每个畴区域一一对应，并位于每个所述畴区域的中心位置。可以理解的是，与所述红色子像素11、绿色子像素12、所述蓝色子像素13为四畴结构相同的是，所述白色子像素区域21也可以位于所述畴区域14内的其它位置。或者，请参阅图8，所述白色子像素20均匀分布于八畴区域的所述子像素的每个所述畴区域14内，即所述白色子像素20包括八个所述白色子像素区域21，每个所述白色子像素区域21与所述白色子像素所在的畴区域14一一对应，并位于每个所述畴区域14的中心位置。可以理解的是，与所述红色子像素11、绿色子像素12、所述蓝色子像素13为四畴结构相同的是，所述白色子像素区域21也可以位于所述畴区域14内的其它位置。由于光线通过所述白色子像素20能够有较大的透过率，因此，通过将所述白色子像素均匀分布于所述子像素的所述畴区域14内，能实现增大所述子像素光线透过率的同时还能够实现所述子像素各个位置的均匀出光，提高光线透过的均一性。
本发明还提供一种彩膜基板，包括基板及上述的像素结构100，所述像素结构位于所述基板上。
本发明明还一种显示面板，包括阵列基板及上述的彩膜基板及位于所述阵列基板与所述彩膜基板之间的液晶层，所述阵列基板与所述彩膜基板相对设置，且所述像素结构100朝向所述阵列基板。背光源发出的光线透过像素结构100进行出光。本发明中，由于所述像素结构100中各子像素的光线透过率均一性较高，所述显示面板也能够实现均匀出光。
以上所揭露的仅为本发明一种较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
