本申请基于2022年12月9日提交的中国专利申请2022115777436主张其优先权，此处通过参照引入其全部的记载内容。
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及显示面板。
背景技术
有机电致发光显示装置，尤其是有机发光二极管(Organic Light-Emitting Diode，OLED)显示面板，因具有自发光、宽视角、快速响应、轻薄化、高对比度等优势，被广泛运用于手机、平板、电脑显示面板等领域。
目前，OLED显示面板包括多个像素单元，每个像素单元包括三个不同颜色的子像素，通过控制不同颜色的子像素的发光程度以显示不同色彩的画面。为使像素单元的颜色分布较为均匀以保证画面显示品质，通常采用标准的RGB排列方式。但是由于不同颜色的子像素的发光材料不同，导致三种颜色的子像素的发光寿命不同，加之人眼对不同颜色感知程度不同，标准的子像素排列方式会导致显示面板在使用后期出现画面偏色问题。现有技术中，通过将发光亮度衰减较慢的子像素的面积减小的方式缩短不同颜色的子像素间的发光寿命的差距。
然而，将发光亮度衰减较慢的子像素的面积减小会导致像素的开口面积利用率降低的问题。

其中，所述第一子像素、所述第二子像素与所述本体部和所述延伸部均为矩形；所述第四侧边与所述第二子像素靠近所述第一子像素的侧边在所述第二方向上的距离等于所述预设距离。
其中，所述第一子像素、所述第二子像素和所述本体部均为矩形；所述第四侧边包括弧形边，所述弧形边连接于所述本体部靠近所述第二子像素的侧边，且所述第二子像素靠近所述延伸部的顶点与所述弧形边上的任意一点之间的距离等于所述预设距离。
其中，所述第一子像素为矩形，所述第二子像素靠近所述本体部的侧边与所述第二子像素靠近所述第一子像素的侧边之间的夹角为锐角或钝角，所述本体部靠近所述第二子像素的侧边与所述第二子像素靠近所述本体部的侧边相互平行，且所述本体部靠近所述第二子像素的侧边与所述第二子像素靠近所述本体部的侧边的垂直距离等于所述预设距离。
其中，所述第四侧边与所述延伸部靠近所述第一子像素的侧边之间的夹角为钝角，且所述第二子像素靠近所述延伸部的顶点与所述第四侧边的垂直距离等于所述预设距离。
其中，所述第四侧边包括弧形边，所述弧形边连接于所述本体部靠近所述第二子像素的侧边，且所述第二子像素靠近所述延伸部的顶点与所述弧形边上的任意一点之间的距离等于所述预设距离。

下面结合附图和实施例对本申请进行详细的说明。
请参阅图1，图1是本申请一实施例提供的像素结构的平面结构示意图。在本实施例中，提供一种像素结构1，该像素结构1可用于显示 面板100，特别是OLED显示面板100。该像素结构1包括多个像素单元10，多个像素单元10可根据预设的排布方式设置，以用于显示图像。具体地，多个像素单元10呈多行多列排布，整体形状和大小可根据显示面板100的显示区101的形状和大小进行设置；每个像素单元10的形状可为矩形、三角形、四边形、多边形或其他不规则形状，具体可根据实际需要进行设置，对此不做具体限定。在本实施例中，多个像素单元10呈多行多列排布，整体排布为矩形，每个像素单元10为矩形，且每个像素单元10的开口形状也为矩形，像素结构1的具体结构和功能请参见下文实施例中的具体描述。
请参阅图2，图2是本申请第一实施例提供的像素单元的结构示意图。在本实施例中，提供一种像素单元10，该像素单元10包括第一子像素11、第二子像素12和第三子像素13，分别用于发射三种不同颜色的光，可通过控制每个像素单元10中第一子像素11、第二子像素12和第三子像素13的发光亮度，使不同发光亮度的光叠加混合实现显示不同的彩色画面。具体地，第一子像素11为红色子像素，用于发射红色光；第二子像素12为绿色子像素，用于发射绿色光；第三子像素13为蓝色子像素，用于发射蓝色光，即第一子像素11、第二子像素12和第三子像素13用于发射三原色光，从而实现画面的全彩化显示。
在本申请实施例中，定义第一方向X与第二方向Y相交设置，第一方向X与第二方向Y可以任意预设角度相交设置，在本实施例和下文实施例中，以第一方向X与第二方向Y相互垂直为例进行说明。沿第一方向X，第一子像素11和第二子像素12位于第三子像素13的同一侧，第一子像素11和第二子像素12分别与第三子像素13相对设置，且第一子像素11与第二子像素12沿第二方向Y相对设置；其中，第一子像素11和第二子像素12分别与第三子像素13相对设置，表示第一子像素11与部分第三子像素13在第一方向X上正对设置，第二子像素12与另一部分第三子像素13在第一方向X上正对设置；第一子像素11与第二子像素12沿第二方向Y相对设置，表示第一子像素11与第二子像素12在第二方向Y上正对设置；即，第一子像素11与第二子像素12在第二 方向Y上排列为一列，第三子像素13单独为一列，且第一子像素11和第二子像素12在第一方向X上分别与第三子像素13正对设置。
其中，第一子像素11、第二子像素12以及第三子像素13的面积依次增大，由于第一子像素11、第二子像素12和第三子像素13的发光材料的亮度衰减速率依次增大，通过调整第一子像素11、第二子像素12和第三子像素13的面积，使红色子像素的面积＜绿色子像素的面积＜蓝色子像素的面积，从而使得第一子像素11、第二子像素12和第三子像素13的发光寿命趋于相同，从而有效降低在显示面板100使用后期，因第三子像素13的发光亮度衰减过快导致显示画面出现偏红的现象。
具体地，第三子像素13包括本体部131和延伸部132，本体部131沿第二方向Y延伸，延伸部132连接于本体部131，并沿第一方向X朝第一子像素11延伸，且与第一子像素11相对设置。即，延伸部132位于本体部131靠近第一子像素11的一侧，且与第一子像素11在第一方向X上正对设置，使得延伸部132设置于面积最小的第一子像素11与本体部131之间的空置的区域，不仅增加了第三子像素13的面积，以延长第三子像素13的发光寿命，而且使得第一子像素11、第二子像素12和第三子像素13在像素单元10的有限空间内排布地更加紧凑，能够充分利用像素单元10的开口面积，从而有效提高了该像素结构1的像素单元10的开口面积的利用率，提升该像素结构1的发光亮度。
如图2所示，本体部131包括沿第二方向Y相对设置的第一侧边1311和第二侧边1312，延伸部132包括第二方向Y相对设置的第三侧边1321和第四侧边1322。具体地，第一子像素11远离第二子像素12的侧边、第三侧边1321以及第一侧边1311在第一方向X上平齐，即，第一子像素11远离第二子像素12的侧边、第三侧边1321以及第一侧边1311位于同一直线，且该直线沿第一方向X延伸；第一子像素11远离第三子像素13的侧边与第二子像素12远离第三子像素13的侧边在第二方向Y上平齐，即，第一子像素11远离第三子像素13的侧边与第二子像素12远离第三子像素13的侧边位于同一直线，且该直线沿第二方向Y延伸；第二子像素12远离第一子像素11的侧边与第二侧边1312 在第一方向X上平齐，即，第二子像素12远离第一子像素11的侧边与第三子像素13的第二侧边1312位于同一直线，且该直线沿第一方向X延伸。容易看出，通过上述设置，第一子像素11、第二子像素12和第三子像素13的外侧的侧边沿所在像素单元10的外边缘设置，使得第一子像素11、第二子像素12和第三子像素13的整体形状与像素单元10的形状相匹配，能够充分利用像素单元10内的空间，减少空间浪费，提升像素单元10的发光面积，提高像素单元10的面积利用率。
进一步地，第一子像素11与延伸部132之间的间距、第一子像素11与第二子像素12之间的间距、以及第二子像素12与本体部131之间的间距均相等，且等于预设距离L；第二子像素12靠近第一子像素11的侧边上的任意一点与第四侧边1322上的任意一点之间的距离大于或等于预设距离L。具体地，为避免子像素在蒸镀或光刻等制程中各自的掩膜板带来的阴影导致第一子像素11、第二子像素12和第三子像素13的膜层出现交叉重叠的问题，各子像素之间需要保持一定的间距，该间距为预设距离L，预设距离L的范围为10μm至40微米之间，例如将预设距离L设置为11μm、13μm、15μm、16μm、18μm、20μm、22μm、25μm、27μm、30μm、32μm、35μm、37μm或39μm，具体可根据实际需求以及制程限制等情况进行设置。具体地，将第一子像素11与延伸部132之间的间距、第一子像素11与第二子像素12之间的间距、以及第二子像素12与本体部131之间的间距均设置为相等的预设距离L，同时，使第二子像素12靠近第一子像素11的侧边上的任意一点与第四侧边1322上的任意一点之间的距离大于或等于预设距离L，从而使像素单元10中的各子像素之间的间距在满足预设距离L的要求的情况下，能够使像素单元10的面积使用更大化，有效提高显示亮度。本申请实施例中所提到的像素单元10的面积或开口面积，是指像素单元10边缘围设形成的内部空间的面积。
进一步地，第一子像素11、第二子像素12、本体部131以及延伸部132均为矩形，且第四侧边1322与第二子像素12靠近所述第一子像素11的侧边在第二方向Y上的距离等于预设距离L。具体地，由第二 子像素12远离第一子像素11的侧边与本体部131的第二侧边1312沿第一方向X平齐，且第二子像素12为矩形，可知第二子像素12靠近第一子像素11的侧边也沿第一方向X延伸；由延伸部132的第三侧边1321与本体部131的第一侧边1311沿第一方向X平齐，且延伸部132为矩形，可知第四侧边1322也沿第一方向X延伸，则第四侧边1322与第二子像素12靠近第一子像素11的侧边相互平行，则第四侧边1322与第二子像素12靠近所述第一子像素11的侧边在第二方向Y上的距离等于二者之间的垂直距离，从而保证了第二子像素12与延伸部132之间的间距大于等于预设距离L，从而使延伸部132的设置与第一子像素11之间的距离以及与第二子像素12之间的距离都能够在制程限制的情况下达到更小值，即减小了延伸部132与第一子像素11之间的间距和与第二子像素12之间的间距，有效提高了像素单元10的面积的利用率，增大了像素单元10的发光面积，从而有效提高显示亮度。通过实验数据计算分析，本实施例中的像素单元10的面积利用率为41.66％，目前常见的像素单元10的子像素的排布方式，其像素单元10的面积利用率最高为39％，本实施例中相比于常见的子像素排布方案，能够有效提高像素单元10的面积利用率。
请参阅图3，图3是本申请第二实施例提供的像素单元的结构示意图。在本实施例中，第一子像素11、第二子像素12和本体部131均为矩形，延伸部132的第四侧边1322包括弧形边1323，弧形边1323连接于本体部131靠近第二子像素12的侧边，且第二子像素12靠近延伸部132的顶点A与弧形边1323上的任意一点之间的距离等于预设距离L；即，当延伸部132与第二子像素12在第二方向Y上的投影有重叠部分时，延伸部132的第四侧边1322靠近本体部131的部分(对应于投影不重叠的部分)为弧形边1323，第四侧边1322的剩余部分(对应于投影重叠的部分)为直线，直线与第二子像素12靠近第一子像素11的侧边在第二方向Y上的距离等于预设距离L，弧形边1323上任意一点与第二子像素12靠近延伸部132的顶点A之间的距离等于预设距离L，从而进一步增加了延伸部132的面积，且保证了第二子像素12与延伸 部132之间的间距在预设距离L的范围内，进一步提高了像素单元10的面积的利用率，增大了像素单元10的发光面积；或者，当延伸部132与第二子像素12在第二方向Y上的投影没有重叠部分时，延伸部132的第四侧边1322整体为弧形边1323，且第二子像素12靠近延伸部132的顶点A与弧形边1323上任意一点的距离等于预设距离L，使得第四侧边1322与本体部131靠近第二子像素12的侧边之间的区域得到有效利用，进一步增加了延伸部132的面积，且保证了第二子像素12与延伸部132之间的间距在预设距离L的范围内，进一步提高了像素单元10的面积的利用率，增大了像素单元10的发光面积。
请参阅图4，图4是本申请第三实施例提供的像素单元的结构示意图。在本实施例中，第一子像素11为矩形，第二子像素12靠近本体部131的侧边与第二子像素12靠近第一子像素11的侧边之间的夹角为锐角或钝角，本体部131靠近第二子像素12的侧边与第二子像素12靠近本体部131的侧边相互平行，且本体部131靠近第二子像素12的侧边与第二子像素12靠近本体部131的侧边的垂直距离等于预设距离L。
具体地，第二子像素12靠近本体部131的侧边与第二子像素12靠近第一子像素11的侧边之间的夹角为锐角，即第二子像素12为倒置的直角梯形，直角梯形的为斜边的腰设置于靠近本体部131的一侧，同时本体部131靠近第二子像素12的侧边与第二子像素12靠近本体部131的侧边相互平行，且本体部131靠近第二子像素12的侧边与第二子像素12靠近本体部131的侧边的垂直距离等于预设距离L，即本体部131与第二子像素12之间的间距等于预设距离L。具体地，本实施例中，第二子像素12可包括矩形部121和补偿部122，补偿部122设置于矩形部121靠近本体部131的一侧且连接于矩形部121，相比于第一实施例和第二实施例，本实施例通过将第二子像素12设置为直角梯形，第二子像素12增加了补偿部122的面积，第三子像素13相应减少一部分面积，从而使第二子像素12的面积和第三子像素13的面积的差异不会过大，即避免第三子像素13因增加了延伸部132而导致第三子像素13面积过大，与第二子像素12和第一子像素11的发光寿命不够均衡，本实施例 通过对第二子像素12和第三子像素13的形状和布局重新设计和优化，在像素单元10的有限空间内，使得第一子像素11、第二子像素12和第三子像素13的面积分配更加合理化，不仅提高了像素单元10的面积利用率，而且能够进一步均衡第一子像素11、第二子像素12和第三子像素13的发光寿命，从而有效避免显示面板100在使用后期，出现因第三子像素13的发光亮度衰减过快导致显示画面出现偏红的现象。
请参阅图5，图5是本申请第四实施例提供的像素单元的结构示意图。与第三实施例不同的是，在本实施例中，第二子像素12靠近本体部131的侧边与第二子像素12靠近第一子像素11的侧边之间的夹角为钝角，即第二子像素12为正的直角梯形，直角梯形的为斜边的腰设置于靠近本体部131的一侧，同时本体部131靠近第二子像素12的侧边与第二子像素12靠近本体部131的侧边相互平行，且本体部131靠近第二子像素12的侧边与第二子像素12靠近本体部131的侧边的垂直距离等于预设距离L，即本体部131与第二子像素12之间的间距等于预设距离L。具体地，本实施例中，第二子像素12也可包括矩形部121和补偿部122，补偿部122设置于矩形部121靠近本体部131的一侧且连接于矩形部121，相比于第三实施例，本实施例中第一子像素11和延伸部132与第二子像素12之间的空隙沿第一方向X延伸的长度小于第三实施例中第一子像素11和延伸部132与第二子像素12之间的空隙沿第一方向X延伸的长度，即，本实施例中的显示单元中空置的区域的总面积更少，从而能够进一步提高像素单元10的面积利用率，像素单元10的发光面积更大，在显示图像时亮度更高。
在本实施例中，第四侧边1322可为沿第二方向Y延伸的直线，或者是具有一定斜率的斜边，但需保证第二子像素12靠近延伸部132的顶点A与第四侧边1322的垂直距离等于预设距离L，即使得第二子像素12与延伸部132之间的间距在每一处都等于或大于预设距离L，从而满足制程的距离要求，避免第二子像素12与延伸部132的膜层出现重叠而影响画面显示。
本实施例中，通过实验数据计算分析，本实施例中的像素单元10 的面积利用率为41.82％，相比于第一实施例，本实施例的像素单元10的面积利用率进一步得到提升。
请参阅图6，图6是本申请第五实施例提供的像素单元的结构示意图。与第三实施例不同的是，本实施例中，延伸部132的第四侧边1322包括弧形边1323，弧形边1323连接于本体部131靠近第二子像素12的侧边，且第二子像素12靠近延伸部132的顶点A与弧形边1323上的任意一点之间的距离等于预设距离L。类似于第二实施例，当延伸部132与第二子像素12在第二方向Y上的投影有重叠部分时，延伸部132的第四侧边1322靠近本体部131的部分(对应于投影不重叠的部分)为弧形边1323，第四侧边1322的剩余部分(对应于投影重叠的部分)为直线或斜线，直线或斜线与第二子像素12靠近第一子像素11的侧边在第二方向Y上的距离等于预设距离L，弧形边1323上任意一点与第二子像素12靠近延伸部132的顶点A之间的距离等于预设距离L，从而进一步增加了延伸部132的面积，且保证了第二子像素12与延伸部132之间的间距在预设距离L的范围内，进一步提高了像素单元10的面积的利用率，增大了像素单元10的发光面积；或者，当延伸部132与第二子像素12在第二方向Y上的投影没有重叠部分时，延伸部132的第四侧边1322整体为弧形边1323，且第二子像素12靠近延伸部132的顶点A与弧形边1323上任意一点的距离等于预设距离L，使得第四侧边1322与本体部131靠近第二子像素12的侧边之间的区域得到有效利用，进一步增加了延伸部132的面积，且保证了第二子像素12与延伸部132之间的间距在预设距离L的范围内，进一步提高了像素单元10的面积的利用率，增大了像素单元10的发光面积。
请参阅图7，图7是本申请第六实施例提供的像素单元的结构示意图。同理，与第四实施例不同的是，本实施例中，延伸部132的第四侧边1322包括弧形边1323，弧形边1323连接于本体部131靠近第二子像素12的侧边，且第二子像素12靠近延伸部132的顶点A与弧形边1323上的任意一点之间的距离等于预设距离L，使得第四侧边1322与本体部131靠近第二子像素12的侧边之间的区域得到有效利用，进一步增加了 延伸部132的面积，且保证了第二子像素12与延伸部132之间的间距在预设距离L的范围内，进一步提高了像素单元10的面积的利用率，增大了像素单元10的发光面积。
本实施例中，通过实验数据计算分析，本实施例中的像素单元10的面积利用率为42.16％，相比于以上实施例，本实施例的像素单元10的面积利用率进一步得到提升。
请参阅图8，图8是本申请一实施例提供的显示面板的结构示意图。在本实施例中，提供一种显示面板100，该显示面板100包括显示区101和位于显示区101周围的非显示区102；其中，显示区101用于显示图像，非显示区102用于设置显示面板100的其他结构与元器件。
具体地，显示区101具有像素结构1，像素结构1的具体结构和功能与上文实施例中所涉及的像素结构1的具体结构和功能相同或相似，且可实现相同的技术效果，具体可参考上文具体介绍，此处不再赘述。
本实施例提供的显示面板100，在分辨率不变的情况下，即像素结构1的每个像素单元10的面积不变的情况下，通过对每个像素单元10中的红色子像素、绿色子像素和蓝色子像素的形状和面积以及排布方式进行优化设计，不仅能够有效均衡红色子像素、绿色子像素和蓝色子像素的发光寿命，使它们的发光寿命趋于一致，从而避免该显示面板100在使用后期，因绿色子像素或蓝色子像素的发光亮度衰减过快导致图像显示出现偏红的问题，而且能够有效提高像素单元10的面积利用率，使得像素单元10的面积使用量能够大于41.65％，从而提高了画面显示亮度，进一步提升显示面板100的画面显示品质。
以上所述仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请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，均同理包括在本申请的专利保护范围内。
