Description

OLED显示面板及其制备方法、显示装置 技术领域
本发明的实施例涉及一种OLED显示面板及其制备方法、显示装置。
背景技术
随着平面显示装置的蓬勃发展，有机发光二极管(Organic Light Emitting Diode，OLED)显示面板与传统的液晶显示面板相比，由于具有响应快、色域广、超薄、自发光、能实现柔性化等特点，已逐渐成为新一代平板显示装置的主流。
为了实现OLED显示面板的全彩化，一般是通过顶发射白色有机发光二极管(White Organic Light Emitting Diode，WOLED)和彩色滤光层(ColorFilter，CF)叠加来实现。具有多个WOLED的WOLED层和彩色滤光层的叠加过程不需要使用高精度金属掩膜版来进行掩膜工艺，就可以实现OLED显示器的高分辨率。如图1所示，在分别形成包含WOLED层01的薄膜晶体管(TFT，Thin Film Transistor)阵列基板02和包含彩色滤光层03的封装盖板04之后，在WOLED层01背离阵列基板02的一面设置透明胶材05，然后将封装盖板04形成有彩色滤光层03的一面朝向WOLED层01，并与阵列基板02进行对准、压合，从而形成OLED显示面板。
但是，在图1所示的顶发射WOLED层01与彩色滤光层03相叠加的OLED显示面板中，封装盖板04与阵列基板02对盒连接后，彩色滤光层03与WOLED层01之间具有较厚的一层透明胶材05，使得色滤光层03与WOLED层01之间的间距较大，并且由于WOLED层01具有自发光的光源特性，WOLED层01的与显示面板的一个亚像素单元相对应的区域所发出的光在侧向到达彩色滤光层03的过程中，会穿过透明胶材05射向其它亚像素单元的彩色滤光层上，从而造成产品混色，使OLED显示面板出现大视角色偏问题，影响了OLED显示面板的显示效果。

具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供一种OLED显示面板。请参考图2，为本发明实施例 提供的OLED显示面板的结构示意图，其中，该OLED显示面板包括：相对设置的阵列基板1和封装盖板2，以及设置于阵列基板1朝向封装盖板2一面的OLED层3。该OLED显示面板还包括：
第一薄膜封装层4，其覆盖OLED层3，并与阵列基板1粘接；
彩色滤光层5，位于第一薄膜封装层4朝向封装盖板2的一侧；
填充于阵列基板1与封装盖板2之间、以粘接阵列基板和封装盖板的贴合胶材6，贴合胶材6覆盖彩色滤光层5和第一薄膜封装层4。
本实施例提供的OLED显示面板中，由于设置了覆盖OLED层3、与阵列基板1粘接的第一薄膜封装层4，并将彩色滤光层5形成于第一薄膜封装层4朝向封装盖板2的一面，而贴合胶材6是位于彩色滤光层5背离OLED层3的一侧；这样，OLED层3与彩色滤光层5之间仅具有了第一薄膜封装层4，OLED层3与彩色滤光层5之间的间距则为第一薄膜封装层4的厚度，且薄膜封装层的厚度远小于贴合胶材的厚度。因此，本实施例提供的OLED显示面板中，OLED层3与彩色滤光层5之间的间距较小，能够防止显示面板中与一个亚像素单元对应的OLED层3中发光区所发出的光照射到其它亚像素单元的彩色滤光层5上，从而能够防止造成产品混色，有利于缓解OLED显示面板出现大视角色偏的问题，增大了OLED显示面板的可视角度，提高了显示效果。
另外，请参考图1，现有的WOLED层01包括相对设置的阳极011和阴极012，以及位于阳极011和阴极012之间、由有机材料制作而成的电激发光层013，由于用于制作电激发光层013的有机材料以及用于制作阴极012的活泼金属都对水汽极其敏感，容易受到水汽的侵蚀。而现有技术中，WOLED层01与彩色滤光层03之间为透明胶材05，且透明胶材05与WOLED层01中的阴极012接触，所以对盒后的OLED显示面板的阻水能力主要依托于透明胶材05的阻水性。但是，一般透明胶材05的阻水性有限，水汽容易渗透进透明胶材05内与WOLED层01的阴极012和电激发光层013接触，造成阴极012和电激发光层013被水汽侵蚀，从而使OLED显示面板的产品可靠性降低。
与现有技术相比，本实施例提供的OLED显示面板中，OLED层3外包覆了第一薄膜封装层4，且第一薄膜封装层4与阵列基板1粘接，从而将OLED 层3封装于阵列基板1，然后，通过覆盖彩色滤光层5和薄膜封装层4的贴合胶材6将阵列基板1与封装盖板2连接以实现阵列基板与封装盖板的对盒连接。这样，对盒完成的OLED显示面板中，贴合胶材6可以起到第一层阻水作用，隔绝外部环境中的大部分水汽以保护OLED层3；第一薄膜封装层4可以将OLED层3和贴合胶材6隔离，以起到第二层阻水作用，防止渗透进贴合胶材6内的水汽与OLED层3接触，进一步保护OLED层3中的阴极和电激发光层等不被水汽侵蚀，提高了OLED显示面板的产品可靠性。
例如，根据本发明实施例的OLED显示面板还包括第二薄膜封装层7，该第二薄膜封装层7设置在贴合胶材6和彩色滤光层5之间。这样一来，在OLED层3和贴合胶材6之间具有两层薄膜封装层，提高了OLED显示面板的阻水能力。
例如，第一薄膜封装层4和第二薄膜封装层7密封连接为一个整体，进一步提高阻水能力。同时，第一薄膜封装层4和第二薄膜封装层7密封连接后，可以将彩色滤光层5封装于两薄膜封装层之间，从而还可以防止渗透进贴合胶材6内的水汽对彩色滤光层5造成侵蚀。
请继续参考图2，例如，上述彩色滤光层5包括与显示面板的亚像素单元一一对应的多个单色滤光单元51。
例如，上述的第一薄膜封装层4和第二薄膜封装层7为氮化硅SiNx、氧化硅SiOx或氮氧化硅SiOxNy材料制作而成的薄膜封装层。由SiNx、SiOx或SiOxNy材料制作而成的薄膜封装层具有良好的阻水能力，有利于提高OLED显示面板的阻水能力。
例如，第一薄膜封装层4具有单层结构或多层结构。例如，第二薄膜封装层7具有单层结构或多层结构。
当然，上述的第一薄膜封装层4和第二薄膜封装层7除了可以采用上述材料制作而成之外，还可以采用其它透明的无机材料制作而成，只要其能够起到良好的阻水作用即可，此处不再一一赘述。
需要说明的是，上述的第一薄膜封装层4和第二薄膜封装层7可以由相同的材料制成，也可以由不同的材料制成。
例如，贴合胶材6可以为坝胶、填充胶、面胶、光学透明双面胶(Optically Clear Adhesive，OCA)或光学透明胶(Optically Clear Resin，OCR)，但不 限于上述这些有机胶材，也可以采用其它透明有机胶材，此处不再一一赘述。其中，贴合胶材6可以采用坝填充封装或面封装的方式进行设置。
请参考图2，例如，OLED层3为具有多个白色有机发光二极管WOLED的WOLED层；彩色滤光层5中任意相邻的两个单色滤光单元51的颜色不同，且每一种单色滤光单元51对应WOLED层的一个白色有机发光二极管WOLED。
WOLED层与彩色滤光层5相叠加的OLED显示面板不需要使用高精度金属掩膜版进行掩膜操作，使阵列基板1和WOLED层的制备过程较为简单。
例如，本发明实施例提供的OLED显示面板的彩色滤光层5中的各单色滤光单元51可以采用以下三种设置方式进行设置：
方式一，请参考图2和图3，上述彩色滤光层5中具有的多个单色滤光单元51为红色滤光单元R、绿色滤光单元G、白色滤光单元W和蓝色滤光单元B，且彩色滤光层5中的多个单色滤光单元51背离阵列基板1的一面位于同一平面，有利于OLED显示面板的薄型化设计。而且，彩色滤光层5中除了设置红色滤光单元R、绿色滤光单元G和蓝色滤光单元B外，还设置了白色滤光单元W，有利于增强OLED显示面板的显示亮度，从而提高显示效果。
在上述方式一的基础上，同一个像素单元中，如图2中所示，任意相邻的两个单色滤光单元51相接触，或者，如图3中所示，任意相邻的两个单色滤光单元51之间设置有黑矩阵7。
相邻的两个单色滤光单元51之间设置黑矩阵7，以阻挡一个单色滤光单元51对应的WOLED层的发光区所发出的光束中射向该单色滤光单元51两侧的光线，以防止该单色滤光单元51对应的WOLED层的发光区所发出的光线照射到其它单色滤光单元51上，进一步有利用缓解OLED显示面板出现的大视角色偏问题，提高OLED显示面板显示效果。
方式二，请参考图4，上述彩色滤光层5中具有的多个单色滤光单元51为红色滤光单元R、绿色滤光单元G和蓝色滤光单元B，同一个像素单元中任意相邻的两个单色滤光单元51接触，且具有交叠区域。
在具有红色滤光单元R、绿色滤光单元G和蓝色滤光单元B的同一像素单元中，相邻的两个颜色不同的单色滤光单元51之间设置相互交叠的区域 后，则交叠区域可以阻挡一种颜色的单色滤光单元51对应的WOLED层的发光区所发出的白光光束中的光线射向另一种颜色的单色滤光单元51，从而可以防止造成混光现象。例如图4中所示，以相邻的红色滤光单元R和绿色滤光单元G为例，绿色滤光单元G边缘的一部分区域叠加在红色滤光单元R背离阵列基板1的一面，红色滤光单元R相对的一部分WOLED层的发光区所发出的白光光束中，靠近绿色滤光单元G的部分光线中的红光可以透过红色滤光单元R，而透过红色滤光单元R的红光在照射至叠加于红色滤光单元R上的绿色滤光单元G时，则会被绿色滤光单元G阻拦而不能透过，从而可以防止红色滤光单元R对应的亚像素单元与绿色滤光单元G对应的亚像素单元之间造成混光现象，进一步有利于缓解OLED显示面板出现的大视角色偏问题，提高了OLED显示面板的显示效果。
方式三，请参考图5，上述彩色滤光层5中具有红色滤光单元R、绿色滤光单元G和蓝色滤光单元B，同一个像素单元中多个单色滤光单元51互不接触，且任意相邻的两个单色滤光单元51在阵列基板1上的投影具有重叠部分。
在具有红色滤光单元R、绿色滤光单元G和蓝色滤光单元B的同一像素单元中，相邻的两个颜色不同的单色滤光单元51在阵列基板1上的投影具有重叠部分后，WOLED层的发光区所发出的光束中的光线透过靠近阵列基板的一种颜色的单色滤光单元51边缘后，得到与该单色滤光单元51颜色相同的单色光，并继续沿直线传播至另一种颜色的单色滤光单元51，从而可以被另一种颜色的单色滤光单元51阻拦，以防止造成混光现象。例如图5中所示，以相邻的红色滤光单元R和绿色滤光单元G为例，绿色滤光单元G在阵列基板1上的投影与红色滤光单元R在阵列基板1上的投影具有重叠部分，红色滤光单元R相对的一部分WOLED层的发光区所发出的白光光束边缘，靠近绿色滤光单元G的部分光线中的红光透过红色滤光单元R后，继续沿直线传播并照射至绿色滤光单元G时，则会被绿色滤光单元G阻拦而不能透过，从而可以防止红色滤光单元R对应的亚像素单元与绿色滤光单元G对应的亚像素单元之间造成混光现象，进一步有利于缓解OLED显示面板出现的大视角色偏问题，提高OLED显示面板的显示效果。
请继续参考图5，在上述方式三的基础上，例如，在同一个像素单元的 数个单色滤光单元51中，一个单色滤光单元51朝向阵列基板1的一面和与其相邻的单色滤光单元51朝向阵列基板1的一面不处于同一平面。如图5中所示，绿色滤光单元G朝向阵列基板1的一面和与其相邻的蓝色滤光单元B、红色滤光单元R朝向阵列基板1的一面不处于同一平面，以利于实现在数个单色滤光单元51互不接触的情况下，使任意相邻的两个单色滤光单元51在阵列基板1上的投影能够具有重叠部分。
本发明实施例还提供了一种显示装置，其包括上述任一OLED显示面板。
由于上述实施例提供的OLED显示面板中，OLED层3与彩色滤光层5之间的间距较小，能够防止OLED层3中与显示面板中一个亚像素单元对应的发光区所发出的光照射到其它亚像素单元的彩色滤光层5上，从而能够防止混光现象，有利于缓解OLED显示面板出现的大视角色偏问题。因此，本发明实施例提供的具有上述OLED显示面板的显示装置中，OLED显示面板出现的大视角色偏问题能够得到有效缓解，从而有利于增大本发明实施例提供的显示装置的可视角度，提高了显示效果。
本发明实施例还提供了一种OLED显示面板的制备方法。该方法包括：
步骤S601：在阵列基板上形成包括多个有机发光二极管OLED的OLED层；
步骤S602：在OLED层上形成第一薄膜封装层；
步骤S603：在第一薄膜封装层上形成彩色滤光层；
步骤S604：填充贴合胶材；
步骤S605：将封装盖板压合于所述贴合胶材。
基于上述OLED显示面板所具有的优点，在通过本发明实施例提供的制备方法制备的OLED显示面板中，OLED层与彩色滤光层之间的间距较小，能够防止与显示面板中一个亚像素单元对应的OLED层的发光区所发出的光照射到其它亚像素单元的彩色滤光层上，进而可以防止产品混色，有利于缓解OLED显示面板出现大视角色偏的问题。
例如，步骤S603中，彩色滤光层包括与显示面板的亚像素单元一一对应的多个单色滤光单元，且多个单色滤光单元通过热蒸镀、干涉滤光片镀制或激光转写镀制的方式镀制于所述薄膜封装层。
当然，彩色滤光层中单色绿光单元的镀制方式并不限于上述的这些镀制 方式，也可以采用其它镀制方式，此处不再一一赘述。
以上所述仅是本发明的示范性实施方式，而非用于限制本发明的保护范围，本发明的保护范围由所附的权利要求确定。
