Description

一种彩膜基板及有机发光显示面板 技术领域
本发明涉及显示技术领域，尤其涉及一种彩膜基板及有机发光显示面板。
 背景技术
随着显示技术的发展及市场需求的变更，近年来柔性屏成为热门研究对象及市场趋势。柔性屏主要是指柔性有机发光二极管（OLED），因可在塑料基板上制备器件，且使用塑料模组材料而非玻璃盖板能够获得很好的弯曲特性，但因为OLED使用圆偏光片使得面板厚度大且功耗高；偏光片（POL）能够有效地降低强光下面板的反射率，却损失了接近58%的出光，这对于OLED来说，极大地增加了其寿命负担；另一方面，偏光片厚度较大、材质脆，弯折曲率半径受到限制，不利于柔性屏产品的开发。为了开发基于OLED现实技术的柔性产品，必须导入新材料、新技术以及新工艺替代偏光片。
使用彩膜（Color Filter）替代偏光片（POL）的技术被归属为无偏光片（POL-less）技术，能够降低面板的厚度同时增加出光率并减小功耗，彩膜由红（Red）、绿(Green)、蓝（Blue）色阻以及黑色矩阵（Black Matrix，BM）组成，在OLED面板之中，R/G/B色阻分别承担着对应电致发光 R/G/B子像素单元的出光；黑色矩阵则主要承担着防止面板的漏光与降低面板的反射的作用。
但当前显示面板由于阵列基板的电阻压降（IR drop）导致面板色度亮度差异，同时由于薄膜封装（TFE）原因导致有效显示区中心与有效显示区周边颜色不均，而且位于显示面板的四个边角区域的周边还存在颜色发粉的问题(白画面偏粉色)，最终使得显示面板色/亮均一性较差。
 技术问题
发明的目的在于，提供一种彩膜基板及有机发光显示面板，用以解决目前显示面板由于阵列基板的电阻压降（IR drop）导致面板色度亮度差异，同时由于薄膜封装（TFE）原因导致有效显示区中心与有效显示区周边颜色不均，而且位于显示面板色的四个边角区域的周边还存在颜色发粉的问题，最终使得显示面板色/亮均一性较差的技术问题。

 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在本申请中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
具体的，请参阅图1、图2、图3，本申请一实施例提供一种有机发光显示面板100，包括彩膜基板10、阵列基板20以及驱动芯片30。如图1所示，所述阵列基板20设有绑定区201和显示区202，在绑定区201内绑定有驱动芯片30。如图1所示，所述阵列基板20从下至上包括依次层叠设置的驱动电路层1、发光功能层2和薄膜封装层3，具体的，所述发光功能层2设于所述驱动电路层1上，所述薄膜封装层3设于所述发光功能层2上起隔绝水氧作用，所述驱动芯片30通过所述驱动电路层1电连接至所述发光功能层2，用于驱动所述发光功能层2发光。所述彩膜基板10设置于所述阵列基板20上方，亦即所述薄膜封装层3设置于所述发光功能层2与所述彩膜基板10之间。
如图1、图2所示，所述阵列基板20的显示区202内设有所述发光功能层2，所述发光功能层2包括多个所述像素单元21。所述像素单元21包括至少两个子像素，优选包括第一子像素211、第二子像素212和第三子像素213，所述第一子像素211为红色子像素，所述第二子像素212为绿色子像素，所述第三子像素213为蓝色子像素。
如图3所示，本申请一实施例中，所述色阻层6包括多个红色色阻61、多个绿色色阻62与多个蓝色色阻63，所述红色色阻61、所述绿色色阻62与所述蓝色色阻63均分别设于所述透光口51内，所述红色色阻61与第一子像素211对应设置。相应的，所述绿色色阻62与第二子像素212对应设置。可理解的是，本实施例所述至少两个子像素还包括第三子像素213，所述蓝色色阻63与第三子像素213对应设置。
如图1所示，所述彩膜基板10设有玻璃基板4，以及设于所述玻璃基板4同一侧的遮光层5和色阻层6。所述遮光层5上设有阵列式排布的多个透光口51，每一所述透光口51用于对应一个所述子像素的位置设置。所述色阻层6设于所述透光口51内，从而所述色阻层6与所述遮光层5同层设置。两个所述透光口51之间具有所述遮光层5，亦即两个子像素之间有所述遮光层5隔开。
如图3、图4所示，所述彩膜基板10呈矩形，设有上侧边11、下侧边12、左侧边13、右侧边14；所述下侧边12适于对应有机发光显示面板的驱动芯片30侧设置；所述彩膜基板10定义有周围区域110与中间区域120，所述周围区域110包围所述中间区域120且对应所述上侧边11、所述下侧边12、所述左侧边13、所述右侧边14区分成上侧区域111、下侧区域112、左侧区域113、右侧区域114；本申请一实施例所述至少两个子像素为第一子像素211与第二子像素212，所述下侧区域112、所述左侧区域113、所述右侧区域114与所述中间区域120的所述透光口51从所述上侧边11至所述下侧边12的方向开口逐渐减小，所述上侧区域111中对应所述第一子像素211的所述透光口51的开口小于所述中间区域120中最靠所述上侧区域111的所述第一子像素211对应的所述透光口51的开口。
具体的，所述有机发光显示面板100对应所述上侧区域111容易有颜色发粉的问题(白画面偏粉色)。所述第一子像素211为红色子像素。如图5a所示，将所述彩膜基板10的所述上侧区域111对应红色子像素211的所述透光口51(透光口内设置红色色阻61)的开口减小以降低红光的出光通量，降低所述上侧区域111颜色发粉的问题，提升色/亮均一性。
具体的，所述阵列基板20上的所述像素单元21由于电阻压降（IR drop），越靠近所述上侧边11的所述像素单元21亮度越低。越靠近所述下侧边12的所述像素单元21亮度越高，所以将所述彩膜基板10的所述下侧区域112、所述左侧区域113、所述右侧区域114与所述中间区域120中的所述透光口51设置为从所述上侧边11至所述下侧边12的方向开口逐渐减小以平衡电阻压降造成的亮度差异。
本申请一实施例通过将所述彩膜基板10不同位置的所述遮光层5的所述透光口51开口逐步变化，实现所述彩膜基板10不同位置的开口率不同，使得从远离驱动芯片30侧的上侧边11至对应驱动芯片30侧的下侧边12，所述遮光层5的开口率逐渐减小，以此来补偿有机发光显示面板色/亮不均的区域，以提升色/亮均一性，能够解决由于阵列基板20的电阻压降（IR drop）导致面板色度亮度差异的技术问题。
具体的，本申请一实施例中，如图5b所示，所述有机发光显示面板100对应所述左侧区域113及所述右侧区域114容易有颜色发粉的问题(白画面偏粉色)。将所述彩膜基板10的所述左侧区域113，阵列式排布的所述多个透光口51的每一行所述透光口51中，对应所述第一子像素211的所述透光口51(对应红色色阻61)的开口设置为小于所述中间区域120中该行所述透光口51中对应所述第一子像素211的所述透光口51(对应红色色阻61)的开口大小。相应的，在所述右侧区域114，阵列式排布的所述多个透光口51的每一行所述透光口51中，对应所述第一子像素211的所述透光口51(对应红色色阻61)的开口小于所述中间区域120中该行所述透光口51中对应所述第一子像素211的所述透光口51(对应红色色阻61)的开口大小。所述第一子像素211为红色子像素。将所述左侧区域113及所述右侧区域114对应红色子像素的所述透光口51的开口相对所述中间区域120中对应该行红色子像素设置的同行红色子像素的所述透光口51减小以降低红光的出光通量，降低所述左侧区域113及所述右侧区域114相对所述中间区域120颜色发粉的问题，提升色/亮均一性。
具体的，所述阵列基板20上的所述像素单元21由于电阻压降（IR drop），越靠近所述左侧边13、所述右侧边14的所述像素单元21亮度越高。越靠近所述中间区域120的所述像素单元21亮度越低，所以将所述彩膜基板10的所述左侧区域113、所述右侧区域114与所述中间区域120中的位于同一行红色子像素的所述透光口51(对应红色色阻61)设置为从所述左侧边13至所述中间区域120的方向开口逐渐增加，从所述右侧边14至所述中间区域120的方向开口逐渐增加以平衡电阻压降造成的亮度差异。
如图5a、5b所示，所述阵列基板20对应所述中间区域120的所述像素单元21由于电阻压降（IR drop）的降造成的亮度差异不大，对应于从所述左侧边13至所述右侧边14的水平方向上，所述像素单元21电阻压降（IR drop）差异亦不大，可将所述彩膜基板10的所述中间区域120的同一行红色子像素的所述透光口51的开口设置为相同。具体的，本申请一实施例中，在所述中间区域120，阵列式排布的所述多个透光口51的一行所述透光口51中，对应所述第一子像素211的所述透光口51的开口大小相同。在其他实施例中，为了调节些微的电阻压降（IR drop）差异，也可以所述中间区域120的纵向对称轴划分为镜像对称的左右区域，将位于同一行红色子像素的所述透光口51开口尺寸从所述左侧区域113至所述中间区域120的纵向对称轴的方向逐渐增加，从所述右侧区域114至所述中间区域120的纵向对称轴的方向开口逐渐增加以平衡电阻压降造成的亮度差异。
如图5c所示，本申请一实施例中，所述阵列基板20上的所述像素单元21由于电阻压降（IR drop），越靠近所述上侧边11的所述像素单元21亮度越低。越靠近所述下侧边12的所述像素单元21亮度越高，所以将所述彩膜基板10的所述中间区域120中的所述透光口51设置为从所述上侧边11至所述下侧边12的方向开口逐渐减小以平衡电阻压降造成的亮度差异。但是对应于所述中间区域120的中央位置处，所述像素单元21电阻压降（IR drop）差异不明显。因此，具体的，将所述彩膜基板10的所述中间区域120从所述上侧边11至所述下侧边12，依次区分为第一区域121、第二区域122及第三区域123，其中，在所述第二区域122中，设置对应所述第一子像素211的所述透光口51(对应红色色阻61)的开口大小均相同，对应所述第二子像素212的所述透光口51(对应绿色色阻62)的开口大小均相同。可理解的是，亦可设置对应所述第三子像素213的所述透光口51(对应蓝色色阻63)的开口大小均相同。另外，对应于所述第一区域121、所述第三区域123的所述像素单元21，由于电阻压降（IR drop）比较明显，因此设置从所述上侧边11至所述下侧边12的方向对应所述第一子像素211、所述第二子像素212、 所述第三子像素213的所述透光口51的开口大小逐渐减小。
请参考图5d所示，本申请一实施例中，在所述上侧区域111、所述下侧区域112、所述左侧区域113、所述右侧区域114与所述中间区域120中，对应所述第二子像素212的所述多个透光口51(对应绿色色阻62)的开口大小，从所述上侧边11至所述下侧边12的方向逐渐减小。
同理，请参考图5d所示，本申请一实施例中，在所述上侧区域111、所述下侧区域112、所述左侧区域113、所述右侧区域114与所述中间区域120中，对应所述第三子像素213的所述多个透光口51(对应蓝色色阻63)的开口大小，从所述上侧边11至所述下侧边12的方向逐渐减小。
如图5e所示，所述彩膜基板10的所述周围区域110呈矩形框结构，其中对应其四个边角区域处的所述阵列基板20还存在所述薄膜封装层3封装所述发光功能层2的原因导致所述中间区域120与所述周围区域110的颜色不均，于显示面板对应所述彩膜基板10的四个边角区域115还存在颜色发粉的问题。针对此问题，还可以进一步减小所述边角区域115中对应所述第一子像素211的所述透光口51(对应红色色阻61)的开口。以此方式减弱在四个边角区域115处的颜色发粉情况，最终使得显示面板色/亮均一性较好。
如图5d所示，对应所述彩膜基板10从所述左侧边13至所述右侧边14的水平方向，所述阵列基板20的所述像素单元21电阻压降（IR drop）差异比较不大。因此，本申请一实施例中，在所述上侧区域111与所述下侧区域112，阵列式排布的所述多个透光口51的一行所述透光口51中，对应所述第一子像素211的所述透光口51(对应红色色阻61)的开口大小相同。
本申请一实施例中，在所述上侧区域111与所述下侧区域112，阵列式排布的所述多个透光口51的一行所述透光口51中，对应所述第二子像素212的所述透光口51(对应绿色色阻62)的开口大小相同，对应所述第三子像素213的所述透光口51(对应蓝色色阻63)的开口大小相同。
由于所述透光口51在所述遮光层5上呈阵列式排布，因此所述透光口51之间间隔设置，任意相邻的两个所述透光口51的中心点的距离相等。优选所述透光口51的形状呈菱形、矩形、圆形或三角形中的任一种。
本发明的有益效果在于，提供一种彩膜基板及有机发光显示面板，通过将彩膜基板不同位置的遮光层的开口率不同，使得从远离驱动芯片侧的上侧边至对应驱动芯片侧的下侧边，所述遮光层的开口率逐渐减小，以此来补偿有机发光显示面板色/亮不均的区域，以提升色/亮均一性。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上对本申请实施例所提供的一种彩膜基板及有机发光显示面板进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
