本发明实施例提供了一种显示装置。请参照图1,图1为本发明实施例提供的显示装置的结构示意图。显示装置1包括基板11、发光结构12以及像素定义层13。
基板11用于承载位于其上的其他结构。基板11可以采用柔性材料或刚性材料制成。具体的,基板11可以为采用聚酰亚胺制成。
发光结构12包括阳极121、空穴注入层122、空穴传输层123、发光层124、电子传输层125、电子注入层126以及阴极127。
阳极121的组成材料可以为氧化铟锡。阳极121用于提供空穴。空穴注入层122用于将阳极121提供的空穴注入空穴传输层123。空穴传输层123用于将空穴传输至发光层124。阴极127的组成材料可以包括锂、镁、钙以及铝等金属材料中的至少一种。阴极127用于提供电子。电子注入层用于将阴极127提供的电子注入到电子传输层125。电子传输层125用于将电子传输至发光层124。空穴和电子在发光层124中符合产生激子,激子在电场的作用下迁移,将能量传递给发光层124,使发光层124中的量子点发光。
具体的,可以先采用喷墨打印的方式在基板11上依次形成阳极121、空穴注入层122、空穴传输层123以及发光层124。然后采用蒸镀或喷墨打印方式在发光层124上依次形成电子传输层125和电子注入层126。最后采用蒸镀方式在电子注入层126上形成阴极127。
在本发明实施例中,发光层124的组成材料包括量子点,其中量子点经聚合物重新配位后形成。在一实施例中,该量子点表面的配体包括酸性羧基、羟基、氨基或硫基中的至少一种。请参照图2,图2为本发明实施例提供的量子点的配位方法的流程示意图。量子点的配位方法的步骤包括:
S101,提供目标量子点以及聚合物,其中目标量子点表面具有第一配体,聚合物具有配位基团。
先提供目标量子点以及聚合物。其中目标量子点和聚合物之间的摩尔比为0.01至0.1之间。可以采用油相高温热解的方法合成目标量子点。具体的,可以将有机金属前驱体溶液注入至配体溶液中,其中配体溶液温度范围为250至300度之间。有机金属前驱体在高温条件下迅速热解并成核,晶核再缓慢形成纳米晶粒。重复上述操作,直至形成核-壳结构的目标量子点。此时的目标量子点表面具有油酸以及油胺等第一配体,会造成量子点团聚。
为了避免目标量子点团聚,本发明实施例采用聚合物,重新对上述目标量子点进行了配位。聚合物的主链包括聚芴、聚乙烯咔唑(Polyvinylcarbazole,PVK)或聚苯乙烯系塑料(Polystyrene,PS)中的至少一种,所述聚合物的侧链包括酸性羧基-COOH、羟基-OH、氨基-NH2或硫基-SH中的至少一种。其中,聚合物的侧链为聚合物的配位基团,即配位基团包括酸性羧基、羟基、氨基或硫基中的至少一种。
在一实施例中,可以通过改变聚合物的合成路线,使配位基团之间的间距范围处于为1-20纳米,以调节量子点的微团聚现象。在一实施例中,聚合物可以为具有高载流子迁移率的聚合物,可以改善发光层124中载流子的传输性能。
步骤S102,将目标量子点和聚合物溶解在溶剂中,使聚合物的配位基团对目标量子点重新进行配位,使目标量子点表面形成第二配体,并使目标量子点表面的第一配体脱离,得到重新配位的量子点。
接下来详细介绍使用聚合物对目标量子点进行重新配位的方法的步骤。具体的,先将目标量子点和聚合物溶解在溶剂中,其中溶剂可以为氯仿。再在室温避光条件下,搅拌12-36小时。这样聚合物可以对目标量子点重新进行配位。如图3所示,目标量子点21表面的第一配体211脱离,聚合物22上的配位基团221附着在目标量子点21的表面,形成第二配体231,得到重新配位的量子点23。综上,可以有效的降低重新配位的量子点的团聚率。在一实施例中,第二配体为聚合物中的侧链,即第二配体包括酸性羧基、羟基、氨基或硫基中的至少一种。最后加入甲醇使重新配位后的量子点沉降,再离心分离出该重新配位后的量子点。
如图1所示,显示装置1还包括像素定义层13。其中,像素定义层13用于界定发光结构12。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
