Description

显示模组以及显示装置 技术领域
本公开的实施例涉及一种显示模组及显示装置。
背景技术
有机发光二极管(OLED)显示具有能耗低等优点，但由于在显示时其中的有机发光二极管的发光亮度要根据显示内容频繁变化，导致其使用寿命较低。为此，目前有将有机发光二极管显示与液晶(LCD)显示结合的技术。这种显示装置中设有有机发光二极管基板，其包括多个配置为发出不同颜色光的有机发光二极管；在有机发光二极管基板出光面外设有液晶面板，其包括多个配置为滤光的子像素；各有机发光二极管发出的光经子像素滤光后成为所需亮度，以执行显示。在这种显示装置中，亮度是靠液晶面板的子像素的滤光控制的，故无需频繁改变有机发光二极管的发光亮度，其使用寿命长。
显然，有机发光二极管基板和液晶面板均需要驱动电路为其提供驱动信号(如栅极扫描信号、数据电压信号、公共电压信号等)才能正常工作，而惯常的驱动电路集成在驱动芯片(Driver IC)中，驱动芯片设置在电路板(PCB,Printed Circuit Board)上，并通过柔性线路板(FPC，Flexible Printed Circuit)与有机发光二极管基板和液晶面板电连接。
可见，以上显示装置中的有机发光二极管基板和液晶面板需要不同的驱动电路分别控制，要使用两组不同的驱动芯片和两个柔性线路板，导致器件数量多、结构复杂、成本高。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开的至少一个实施例提供了一种显示模组100，如图1至图5所示，所述显示模组100包括有机发光二极管基板1和液晶面板2，其中，
有机发光二极管基板1包括基底19和设置在基底19的靠近液晶面板2一侧上的多个有机发光二极管11；以及
液晶面板2包括多个配置为滤光的子像素29。
也就是说，该显示模组100中包括有机发光二极管基板1，在有机发光二极管基板1的基底19上设置有多个有机发光二极管11，各有机发光二极管11可独立发光。
在本公开的实施例中，所述有机发光二极管11可以包括阴极、阳极和有机发光层，还包括其他功能性层，例如，电子注入层、空穴注入层、电子传输层、空穴传输层等。本公开对有机发光二极管11的结构不再进行详细的描述。
在有机发光二极管基板1在出光面外设有液晶面板2，该液晶面板2类似于常规的液晶显示面板，其包括多个子像素29，每个子像素29都可对入射在其上的光进行滤光。因此由每个有机发光二极管11发出的光经过与之对应的子像素29过滤后，即可成为所需亮度的光，以便进行显示。
在本公开的一个实施例中，有机发光二极管11包括多种不同颜色的有机发光二极管11。
也就是说，如图1所示，为了实现彩色显示的效果，有机发光二极管基板1中的多个有机发光二极管11可包括多种不同的颜色，如红光有机发光二极管、绿光有机发光二极管、以及蓝光有机发光二极管等。这样显示模组中就不需要使用彩色滤光膜(彩膜)，结构比较简单。
在本公开的一个实施例中，有机发光二极管11中的每一个均为白光有机发光二极管，其上设有彩色滤光膜111，彩色滤光膜111包括多种不同颜色。
也就是说，如图2所示，为实现彩色显示，也可以全部有机发光二极管11都为发白光的白光有机发光二极管，而白光有机发光二极管上设置有不同颜色的彩色滤光膜111，故白光有机发光二极管射出的光经过彩色滤光膜111的过滤后即可成为相应颜色光。
当然，为实现彩色显示，也可采取其他方式，例如在液晶面板2外侧设置彩色滤光膜111等。
在本公开的一个实施例中，显示模组为双视场显示模组或3D显示模组，其中，每个有机发光二极管11对应两个子像素29，任意有机发光二极管11发出的光经过与其对应的两个子像素29后分别射向第一位置和第二位置。
也就是说，如图3所示，以上显示模组中，有机发光二极管11和子像素29的数量可以是一比二的关系(相邻有机发光二极管11间可设有间隔，例如相邻的有机发光二极管通过黑矩阵隔离)。这样，每个有机发光二极管11即对应两个子像素29(图中标注为“左”、“右”的子像素29)，且通过设置有机发光二极管11和子像素29的位置、有机发光二极管基板1与液晶面板2间的距离等，可保证每个有机发光二极管11发出的光在经过与其对应的两个子像素29后，分别射向不同的位置(如左眼和右眼，或不同视区)，从而实现3D显示或双视场显示。在本公开中，显示模组采用有机发光二极管11发光，而不是采用导光板整体发光，可实现对发光位置的精确控制(只要在不需要发光的位置不设置有机发光二极管即可)，更适于用以上方式的3D显示或双视场显示。
与惯常显示装置不同，根据本公开的实施例的有机发光二极管基板1的基底19为硅基底，其上设置有配置为驱动各有机发光二极管11发光的第一驱动电路91和配置为驱动各子像素29滤光的第二驱动电路92。
由于本公开的实施例的有机发光二极管基板1的基底19不是由玻璃或聚合物构成的，而是采用制备驱动芯片(Driver IC)用的基础材料：硅基底(也称硅片、晶元等)，由此，如图4所示，可用CMOS(互补金属氧化物半导体)形式的基础电路直接在基底19上形成各种门结构91和92，以形成第一驱动电路和第二驱动电路，即，将各驱动芯片中的驱动电路都直接制造在有机发光二极管基板1中，从而本公开的实施例的显示模组不再需要使用单独的驱动芯片，其所用器件数量少、集成度高、结构简单、成本低。
在硅基底上形成门结构可以采用惯常的技术实现，本公开对此不做详述。
在本公开的一个实施例中，第一驱动电路91、第二驱动电路92均设置于基底19邻近液晶面板2一侧上。
在本公开的实施例中，由于硅基底是不透光的，故有机发光二极管11必然位于硅基底靠近液晶面板2的一侧才能使发出的光进入液晶面板2。
第一驱动电路91需要与各有机发光二极管11电连接(如通过栅线、数据线、薄膜晶体管等)，在本公开的一个实施例中，第一驱动电路91与有机发光二极管11设置于基底19的同一侧，便于连接。
第二驱动电路92需要与液晶面板2的子像素29中的相应显示结构(如像素电极、公共电极等)电连接(如通过栅线、数据线、薄膜晶体管等)。在本公开的一个实施例中，第二驱动电路92也设置在基底19靠近液晶面板2的一侧，便于将第二驱动电流92连接至所述显示结构。
在本公开的一个实施例中，液晶面板2包括相互对盒的阵列基板21和盖板基板22；阵列基板21位于液晶面板2靠近有机发光二极管基板1一侧，且阵列基板21靠近盖板基板22一侧上设有薄膜晶体管阵列电路211，薄膜晶体管阵列电路211配置为根据第二驱动电路92的驱动控制各子像素29。
如图1、图2、图5所示，液晶面板2可包括通常的阵列基板21，阵列基板21上设有配置为与各子像素29中的显示结构(如像素电极、公共电极等)相连的薄膜晶体管阵列电路211(包括栅线、数据线、薄膜晶体管等)，第二驱动电路92的信号只要接入各栅线、数据线中，即可实现对各子像素29的驱动和控制。在本公开的一个实施例中，为便于实现薄膜晶体管阵列电路211与第二驱动电路92的电连接，将阵列基板21设置在靠近有机发光二极管基板1一侧上。
当然，液晶面板2中还包括其他常规的结构，如液晶层、上偏光片、下偏光片等，在此不再详细描述。
在本公开的一个实施例中，阵列基板21上设有过孔219，第二驱动电路92通过过孔219与薄膜晶体管阵列电路211电连接。
如图1、图2、图5所示，薄膜晶体管阵列电路211位于液晶面板2内侧(即阵列基板21靠近盖板基板22一侧)。因此，为电连接薄膜晶体管阵列电路211与第二驱动电路92，则可在阵列基板21的玻璃基底中设置过孔 219(TGV，Through Glass Via)，通过该过孔219中的引线或导电柱等，即可实现信号在阵列基板21两侧间的传播。
在本公开的一个实施例中，基底19邻近液晶面板2一侧上设有多个与第二驱动电路92相连的第一连接端81；阵列基板21邻近有机发光二极管基板1一侧设有多个与第一连接端81对应的第二连接端，第二连接端通过过孔219与薄膜晶体管阵列电路211相连；第一连接端81与第二连接端82接触。
也就是说，如图1、图2、图5所示，薄膜晶体管阵列电路211通过过孔219连接至阵列基板21另一侧，并与多个第二连接端82(如Pad)相连。相应地，如图4所示，有机发光二极管11显示基板的基底19上，第二驱动电路92也可与多个第一连接端81(如Pad)相连。这样，在将液晶面板2设在有机发光二极管基板1的出光面外后，相应的第一连接端81和第二连接端82可直接接触，从而实现薄膜晶体管阵列电路211与第二驱动电路92的电连接。
当然，薄膜晶体管阵列电路211与第二驱动电路92的电连接也可通过其他方式实现。例如，第一连接端81和第二连接端82间也可通过导电材料(如各向异性导电胶)电连接；再如，也可通过设于有机发光二极管基板1和阵列基板21侧面外的连接线实现薄膜晶体管阵列电路211与第二驱动电路92的电连接等，在此不再详细描述。
本公开的至少一个实施例提供了一种显示装置，其包括：
上述的显示模组和控制信号源，控制信号源通过连接件与第一驱动电路和第二驱动电路电连接。
在本公开的实施例中，该显示装置可为电子纸、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
控制信号源是指配置为两个驱动电路提供控制信号的器件，其可为与显卡相连的控制电路等，而该控制电路再通过连接件实现与显示模组(例如第一驱动电路和第二驱动电路)的电连接。
在本公开的一个实施例中，连接件为柔性线路板(FPC)。
由于柔性线路板是柔性的，故可允许控制信号源与显示模组间的相对位置变化，使用更加灵活。
在根据本公开的实施例的显示装置中，由于第一驱动电路和第二驱动电 路均位于有机发光二极管基板中，故只要用一个连接件(柔性线路板)即可将它们与控制信号源相连，从而减少了所使用的器件数量，提高了集成度，降低了成本。
以上所述仅是本公开的示范性实施方式，而非用于限制本公开的保护范围，本公开的保护范围由所附的权利要求确定。
本申请要求于2016年4月6日递交的中国专利申请第201620282196.2号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
