Description

一种显示面板及用于显示面板制程的光罩 【技术领域】
本申请涉及显示技术领域，更具体的说，涉及一种显示面板及用于显示面板制程的光罩。
【背景技术】
液晶显示器具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。现有市场上的液晶显示器大部分为背光型液晶显示器，其包括液晶面板及背光模组(backlightmodule)。液晶面板的工作原理是在两片平行的玻璃基板当中放置液晶分子，并在两片玻璃基板上施加驱动电压来控制液晶分子的旋转方向，以将背光模组的光线折射出来产生画面。
其中，薄膜晶体管液晶显示器(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)由于具有低的功耗、优异的画面品质以及较高的生产良率等性能，目前已经逐渐占据了显示领域的主导地位。同样，薄膜晶体管液晶显示器包含液晶面板和背光模组，液晶面板包括彩膜基板(Color Filter Substrate，CF Substrate，也称彩色滤光片基板)、薄膜晶体管阵列基板(Thin Film Transistor Substrate，TFTSubstrate)和光罩(Mask)，上述基板的相对内侧存在透明电极。两片基板之间夹一层液晶分子(LiquidCrystal，LC)。
现有的像素设计采用矩形，矩形带有尖角，即使人眼还是可以看到诸如显示的文字边缘的锯齿感，显示效果有所降低，不细腻的画面也不能满足消费者日益提高的观赏显示图像水平。
【发明内容】
本申请所要解决的技术问题是提供一种提升画面细腻度的显示面板。
此外，本申请还提供一种显示装置。
另外，本申请还提供一种用于所述显示面板制程的光罩。

其中，每个所述像素包括对应不同颜色的子像素。子像素不限于RGB还可以包括W(White白)、Y(Yellow黄)等颜色对应的子像素，色彩更丰富，显示效果也更好。
其中，每个所述子像素包括至少两个单元像素，所述单元像素的形状为圆形。至少两个单元像素、单元像素的形状为圆形具体化了子像素的结构特点，至少两个的数量便于丰富排布式样，圆形为常规形状，方便在加工步骤开设，节省成本。
其中，相邻两个所述单元像素外切。相外切使得单元像素间排布紧密，更好的保障了画面细腻度。
其中，所述子像素包括三个单元像素，两端的所述单元像素与中间的所述单元像素的圆心连线之间的夹角为120°。明确子像素中单元像素的具体排布设置，子像素对应的3个单元像素呈一定角度折线排布，并与相邻子像素中的单元像素相外切，最大程度的在实现画面显示提高上增大子像素的所占面积。
其中，所述子像素是边角为弧线的多边形、椭圆形或圆形。子像素是边角为弧线的多边形，弧线过渡平缓不会产生尖角带来的锯齿感。椭圆形状结构简单，利于通过工艺形成。圆形为常规形状，方便在加工步骤开设，节省成本。
其中，所述扫描线和所述数据线与所述像素的轮廓曲线匹配。扫描线和数据线与像素的轮廓曲线匹配，保障像素弧化后像素电极的正常工作，显示面板能呈现细腻度高的画面。
其中，所述像素结构设置在像素膜层，所述显示面板包括彩膜基板和阵列基板，所述像素结构包括位于彩膜基板的彩色滤光膜，所述彩色滤光膜的边缘至少包括一截弧线段。彩膜滤光片的对应设置便于像素结构更好的发挥作用。

下面结合附图和较佳的实施例对本申请作进一步详细说明。
下面参考图1至图7描述本申请实施例的显示面板的像素结构。显示面板包括阵列基板和彩膜基板，所述阵列基板与彩膜基板相对设置。像素结构在其中为显示面板呈现色彩等方面等服务。如图2所示，其中像素为一个个的矩形，即使人眼还是可以看到文字边缘的锯齿感，并不能给使用者提供细腻度高的显示效果。申请人为此提出了通过Super resolution算法来使画面细腻度提升，此举可达到如图1所示的对比效果，但为此需要增加芯片成本。申请人还提出通过进行高解析度的面板设计也可以提升画面的细腻度，但是UHD(Ultra High Definition超高清)的面板成本较高。它们对于TV、monitor、notebook等显示领域并不经济。
为此，申请人根据以上问题设计出了一种提升画面细腻度的像素结构。
如图3所示为本申请一个实施例的显示面板的像素结构的示意图，本实施例的像素结构包括像素1，所述像素1边缘至少包括一截弧线段。像素1由原来的矩形由改为边缘至少包括一截弧线段，利用优化像素形状的方法，大大较少了文字边缘的锯齿感，使显示图像更细腻，提升了显示效果，面板显示品味更好，使用者能得到更好的观赏体验，同时节省成本，提升产品竞争力。其中多个呈阵列式排布的像素1，每个所述像素1可以为四个角是弧线的矩形，像素1的大小一致，像素1按原来为矩形时排列，行列分明且对齐。
具体的，每个所述像素包括对应不同颜色的子像素。子像素不限于R子像素2、G子像素3、B子像素4还可以包括W(White白)、Y(Yellow黄)等颜色对应的子像素，色彩更丰富，显示效果也更好。
作为本申请的又一个实施例，所述子像素是边角为弧线的多边形、椭圆形或圆形。子像素是边角为弧线的多边形，弧线过渡平缓不会产生尖角带来的锯齿感。椭圆形状结构简单，利于通过工艺形成。圆形为常规形状，方便在加工步骤开设，节省成本。
具体的，如图4所示为本申请一个实施例的显示面板的像素结构的示意图。本实施例中每个所述像素包括沿第一方向依次排布的R子像素2、G子像素3 和B子像素4，所述R子像素2、G子像素3和B子像素4是边角为弧线的多边形。第一方向也就是图中的水平方向为扫描线所在方向，相应的，第二方向也就是竖直方向为数据线所在方向。R子像素2、G子像素3和B子像素4在第一方向上依次排布，子像素是边角为弧线的多边形，弧线过渡平缓不会产生尖角带来的锯齿感。在第一方向上按R子像素2、G子像素3和B子像素4的顺序循环排布，当然也可以是RBG、BGR等顺序。在第二方向上则为纯的R子像素2列、G子像素3列和B子像素4列。子像素不限于R子像素2、G子像素3、B子像素4还可以包括W(White白)、Y(Yellow黄)等颜色对应的子像素，色彩更丰富，显示效果也更好。其中R子像素2、G子像素3和B子像素4可以为四个角是弧线的矩形，R子像素2、G子像素3和B子像素4的大小一致，R子像素2、G子像素3和B子像素4按原来为矩形时排列，行列分明且对齐。当然R子像素2、G子像素3和B子像素4也可以是其他边角是弧线的多边形。
具体的，如图5所示为本申请一个实施例的显示面板的像素结构的示意图。本实施例中每个所述像素包括沿第一方向依次排布的R子像素2、G子像素3和B子像素4，所述R子像素2、G子像素3和B子像素4为椭圆形状。椭圆形状结构简单，利于通过工艺形成。弧线过渡平缓不会产生尖角带来的锯齿感。第一方向也就是图中的水平方向为扫描线所在方向，相应的，第二方向也就是竖直方向为数据线所在方向。在第一方向上按R子像素2、G子像素3和B子像素4的顺序循环排布，当然也可以是RBG、BGR等顺序。在第二方向上则为纯的R子像素2列、G子像素3列和B子像素4列。子像素不限于R子像素2、G子像素3、B子像素4还可以包括W(White白)、Y(Yellow黄)等颜色对应的子像素，色彩更丰富，显示效果也更好。其中R子像素2、G子像素3和B子像素4的大小一致，R子像素2、G子像素3和B子像素4按原来为矩形时排列，行列分明且对齐。
具体的，如图6所示为本申请一个实施例的显示面板的像素结构的示意图。本实施例中每个所述像素包括沿第一方向依次排布的R子像素2、G子像素3 和B子像素4，所述R子像素2、G子像素3和B子像素4为圆形。圆形为常规形状，方便在加工步骤开设，节省成本。弧线过渡平缓不会产生尖角带来的锯齿感。第一方向也就是图中的水平方向为扫描线所在方向，相应的，第二方向也就是竖直方向为数据线所在方向。在第一方向上按R子像素2、G子像素3和B子像素4的顺序循环排布，当然也可以是RBG、BGR等顺序。在第二方向上则为纯的R子像素2列、G子像素3列和B子像素4列。子像素不限于R子像素2、G子像素3、B子像素4还可以包括W(White白)、Y(Yellow黄)等颜色对应的子像素，色彩更丰富，显示效果也更好。其中R子像素2、G子像素3和B子像素4的大小一致，R子像素2、G子像素3和B子像素4按原来为矩形时排列，行列分明且对齐。
作为本申请的又一个实施例，每个所述子像素包括至少两个单元像素，所述单元像素的形状为圆形。至少两个单元像素、单元像素的形状为圆形具体化了子像素的结构特点，至少两个的数量便于丰富排布式样，圆形为常规形状，方便在加工步骤开设，节省成本。
具体的，相邻两个所述单元像素外切。相外切使得单元像素间排布紧密，更好的保障了画面细腻度。
具体的，所述子像素包括三个单元像素，两端的所述单元像素与中间的所述单元像素的圆心连线之间的夹角为120°。明确子像素中单元像素的具体排布设置，子像素对应的3个单元像素呈一定角度折线排布，并与相邻子像素中的单元像素相外切，最大程度的在实现画面显示提高上增大子像素的所占面积。
具体的，如图7所示为本申请一个实施例的显示面板的像素结构的示意图。每个所述像素1包括沿第一方向依次排布的R子像素2、G子像素3和B子像素4，所述R子像素2、G子像素3和B子像素4都包括3个单元像素，所述单元像素为圆形，相邻两个所述单元像素外切。所述R子像素2包括3个R单元像素：第一R单元像素21、第二R单元像素22和第三R单元像素23，所述第一R单元像素21和第二R单元像素22的圆心在第一直线上，所述第二R单元 像素22和第三R单元像素23的圆心在与所述第一直线相交成120°的第二直线上，所述第二R单元像素22的圆心在两条直线的交点处；所述G子像素3单元包括3个G单元像素：第一G单元像素31、第二G单元像素32和第三G单元像素33，所述第一G单元像素31和第二G单元像素32的圆心在第三直线上，所述第二G单元像素32和第三G单元像素33的圆心在与所述第三直线相交成120°的第四直线上，所述第二G单元像素32的圆心在两条直线的交点处；所述B子像素4单元包括3个B单元像素：第一B单元像素41、第二B单元像素42和第三B单元像素43，所述第一B单元像素41和第二B单元像素42的圆心在第五直线上，所述第二B单元像素42和第三B单元像素43的圆心在与所述第五直线相交成120°的第六直线上，所述第二B单元像素42的圆心在两条直线的交点处；所述第一R单元像素21、第一G单元像素31和第一B单元像素41在同一直线上沿第一方向依次排布，所述第二R单元像素22、第二G单元像素32和第二B单元像素42在同一直线上沿第一方向依次排布，所述第三R单元像素23、第三G单元像素33和第三B单元像素43在同一直线上沿第一方向依次排布。这里是单元像素的具体排布形式，子像素对应的3个单元像素呈一定角度折线排布，最大程度的在实现画面显示提高上增大R子像素2、G子像素3和B子像素4的所占面积。第一直线、第三直线与第五直线，这三条直线平行。第二直线、第四直线与第六直线，这三条直线平行。
三个单元像素一体基本构成子像素，第一方向也就是图中的水平方向，相应的，第二方向也就是竖直方向。在第一方向上按R子像素2、G子像素3和B子像素4的顺序循环排布，当然也可以是RBG、BGR等顺序。在第二方向上则为纯的R子像素2列、G子像素3列和B子像素4列。当然，子像素不限于R子像素2、G子像素3、B子像素4还可以包括W(White白)、Y(Yellow黄)等颜色对应的子像素，色彩更丰富，显示效果也更好。
其中各个单元像素大小一致。为保证画面的细腻感，相邻两个所述单元像素外切，也就是如图7所示中非单元像素的部分为三个圆外切所剩余，而非如 图6所示中非子像素的部分为四个圆外切所剩余，所以如图7所示相邻两行的子像素并非在一条沿第二方向的直线上，相应的也有一定错位，但间隔行的子像素则在沿第二方向的直线。
作为本申请的再一个实施例，本实施例公开了一种显示面板，包括像素结构，所述显示面板包括扫描线5、数据线6，多条所述数据线5与多条所述扫描线6依次相交设置形成多个像素区，所述每个像素区对应设置有所述像素结构。关于像素结构的具体结构和连接关系可参见图3至图7，在此不再一一详述。
具体的，所述像素结构设置在像素膜层，所述显示面板包括彩膜基板和阵列基板，所述像素结构包括位于彩膜基板的彩色滤光膜，所述彩色滤光膜的边缘至少包括一截弧线段。彩膜滤光片的对应设置便于像素结构更好的发挥作用。或者，所述像素结构位于阵列基板的像素电极，所述像素电极与彩色滤光膜的位置对应，所述像素电极的边缘至少包括一截弧线段。
具体的，所述像素结构设置在像素膜层，所述像素膜层的边沿有遮光设置。遮光设置确保因像素弧化在边沿位置造成的空位得到缓解。
作为本申请的又一个实施例，所述扫描线5和所述数据线6与所述像素1的轮廓曲线匹配。扫描线5和数据线6与像素1的轮廓曲线匹配。扫描线5和数据线6与像素的轮廓曲线匹配，保障像素弧化后像素电极的正常工作，显示面板能呈现细腻度高的画面。其中，对于如图3至图6所示的像素结构实施例，像素1排布行列分明且对齐，扫描线5和数据线6则分别对应设置在相应的行间、列间空位。第一方向也就是图中的水平方向为扫描线5所在方向，相应的，第二方向也就是竖直方向为数据线6所在方向。
具体的，如图8所示为本申请一个实施例的显示面板的扫描线5、数据线6示意图，这里是对应如图7所示的像素结构实施例的。因为如图7所示实施例中子像素甚而单元像素的排布并非行列垂直对齐，相应的扫描线5和数据线6采用与像素1的轮廓曲线匹配的设置方式，能更好的实现此像素结构下的显示面板品味。
作为本申请的再一个实施例，本实施例公开了一种应用于显示面板制程的光罩，所述光罩包括在对应像素结构的位置有形状对应的透光孔。关于像素结构的具体结构和连接关系可参见图3至图7，在此不再一一详述。光罩可用于彩膜基板在加工R/G/B三基色过程中曝光显影，因此，在R/G/B各光阻涂布后需要使用不同的光罩实现曝光。所述光罩包括有：滤光层；
遮光层，所述遮光层包括多个遮光块，所述遮光块间隔设置，所示遮光块之间便是相应的透光孔位置；载体，所述载体可透光设置，所述滤光层和遮光层设置在所述载体上。
需要说明的是，在上述实施例中，所述基板的材料可以选用玻璃、塑料等。
在上述实施例中，显示面板包括液晶面板、OLED(Organic Light-Emitting Diode)面板、曲面面板、等离子面板等，以液晶面板为例，液晶面板包括阵列基板(Thin Film Transistor Substrate，TFT Substrate)和彩膜基板(Color Filter Substrate，CF Substrate)，所述阵列基板与彩膜基板相对设置，所述阵列基板与彩膜基板之间设有液晶和间隔单元(PS，photo spacer)，所述阵列基板上设有主动开关，主动开关可采用薄膜晶体管(TFT，Thin Film Transistor)，彩膜基板上设有彩色滤光层。
在上述实施例中，彩膜基板可包括TFT阵列，彩膜及TFT阵列可形成于同一基板上，阵列基板可包括彩色滤光层。
在上述实施例中，本申请的显示面板可为曲面型面板。
以上内容是结合具体的优选实施方式对本申请所作的进一步详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本申请的保护范围。
