具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明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发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，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，都属于本发明保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本发明所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排 除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
附图中各膜层部件的形状和大小不反映显示装置的真实比例，目的只是示意说明本发明内容。
电致发光显示器由于其利用自发光原理，容易形成各种黑白态结构，某些特定黑白结构即为光栅结构，由于电致发光显示器的黑态亮度几乎为零，黑白态对比度较高，易于得到低串扰3D显示。因此，采用电致发光显示器作为液晶显示屏的后置光栅实现三维显示，可以得到低串扰的三维显示。虽然采用后置的电致发光显示器作为光栅具有上述优点，但是，电致发光显示器和前置的液晶显示屏均需要单独的驱动芯片进行控制，其驱动相对复杂。
本发明至少一实施例提供一种显示装置，如图1a和图1b所示，包括：具有阵列基板101的液晶显示面板100，通过导电的光学胶(OCA)200固定于阵列基板101下方的电致发光显示基板300，以及如图1a所示绑定于电致发光显示基板300上或如图1b所示绑定于阵列基板101上的驱动芯片400。电致发光显示基板300例如可为有机发光二极管(organic light emitting diode，OLED)显示基板。
液晶显示面板100的阵列基板101上设置有至少贯穿阵列基板101的衬底基板1010的过孔102；如图1a所示，阵列基板101上的信号线103通过过孔102从阵列基板101的上表面引至下表面，经过光学胶200中的导电材料与绑定于电致发光显示基板300上的驱动芯片(IC)400相连。或者，如图1b所示，电致发光显示基板300上的信号线103经过光学胶200中的导电材料，通过过孔102从阵列基板101的下表面引至上表面与绑定于阵列基板101上的驱动芯片400相连。该驱动芯片400被配置为分别向液晶显示面板100和电致发光显示基板300提供电信号。例如，过孔102还可以贯穿设置在阵列基板101的衬底基板上的至少一个绝缘层。本发明实施例的附图中未示出绝缘层。过孔102贯穿哪些层可根据需要而定，本发明的实施例对此不作限定。
一般地，在本发明实施例提供的上述显示装置中的液晶显示面板100， 如图1a、图1b所示，除了具有阵列基板101之外，还会具有与阵列基板101相对而置的对向基板104，设置于对向基板104上表面的上偏光片105，以及设置于阵列基板101下表面的下偏光片106。
例如，本发明实施例提供的上述显示装置中的电致发光显示基板300可以是指具有封装盖板的电致发光显示背板，也可以是采用液晶显示面板的阵列基板作为封装盖板的电致发光显示背板，在此不做限定。
例如，本发明实施例提供的上述显示装置可以为：手机、手表、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。
本发明实施例提供的上述显示装置中，在液晶显示面板100的阵列基板101上设置至少贯穿衬底基板的过孔102后，过孔102中采用注入或渗透的方式填充有导电物质，可以使阵列基板101上的信号线103通过过孔102从阵列基板101的上表面引至下表面，经过光学胶200中的诸如金球(Au ball)的导电材料与绑定在电致发光显示基板300上的驱动芯片400相连，或，可以使电致发光显示基板300上的信号线经过光学胶200中的导电材料，通过过孔102从阵列基板101的下表面引至上表面与绑定于阵列基板101上的驱动芯片300相连，这样，可以仅在电致发光显示基板300上或在阵列基板101之一上绑定驱动芯片400用来分别向液晶显示面板100和电致发光显示基板300提供电信号，省去在液晶显示面板100的阵列基板101或电致发光显示基板300另一个上设置驱动芯片。采用一颗驱动芯片400同时控制液晶显示面板100和电致发光显示基板300，避免了因分别采用单独的驱动芯片进行控制带来的诸如信号同步时易出现的问题，极大地简化了驱动的复杂程度，也节省了成本。
例如，本发明实施例提供的上述显示装置中，采用一颗驱动芯片400同时控制液晶显示面板100和电致发光显示基板300时，可以在驱动芯片400的管脚分别单独对应于电致发光显示基板300中的信号线和液晶显示面板100中的信号线103，此时，由于两个显示面板中的信号线数量较多，会极大增加驱动芯片400的管脚数量，不利于简化驱动过程以及降低驱动芯片400的成本。
因此，当在液晶显示面板100中通过过孔102引至电致发光显示基板300 的信号线103包括数据线时，或，当在电致发光显示基板300中通过过孔102引至液晶显示面板100的信号线103包括数据线时，可以将电致发光显示基板300上的各数据线与液晶显示面板100的阵列基板101上的至少一条数据线共用驱动芯片400的一个管脚，即共同连接于驱动芯片400的同一个接线端子，这样，驱动芯片400可以仅只需支持电致发光显示基板300的数据信号通道即可，使驱动芯片400的成本也得到了降低。
进一步地，在本发明实施例提供的上述显示装置中，由于电致发光显示基板300在进行二维显示时，仅用于提供背光，在进行三维显示时，还用于提供条状光栅，因此，在电致发光显示基板300中的分辨率一般会低于液晶显示面板100中的分辨率。一般地，电致发光显示基板300中的像素列与液晶显示面板100中的像素列可以为一一对应的关系，并且液晶显示面板100中的各像素一般由行方向排列的至少两个子像素组成；由于电致发光显示基板300仅提供背光，因此，电致发光显示基板300中各像素可不划分子像素，这样电致发光显示基板300上的每条数据线对应于电致发光显示基板300中的一列像素。由于液晶显示面板100需要进行图像的色度显示，因此，液晶显示面板100的阵列基板101上的每条数据线对应于液晶显示面板100中的一列子像素。这样，可以将液晶显示面板100的阵列基板101上属于同一像素列的各子像素列对应的各数据线，分别通过一一对应连接的可控开关单元与一个接线端子连接；属于同一像素列的各子像素列对应的各数据线连接各可控开关单元，各可控开关单元被配置来控制连接的数据线与接线端子分时导通。这样，可以通过适用于分辨率较低的电致发光显示基板300的驱动芯片400既提供电致发光显示基板300的数据信号，又提供液晶显示面板100的数据信号。
并且，电致发光显示基板300中各像素的发光颜色为白色，液晶显示面板100中属于同一像素的各子像素的发光颜色各不相同，电致发光显示基板300提供可调节灰阶亮度的背光，背光的功耗能有相应的降低。例如，一个像素包括多个子像素。例如，一个像素包括R、G、B三个子像素，但不限于此。
例如，如图2所示，显示面板的阵列基板上包括多条栅线1011和多条数据线LCD D，多条栅线1011和多条数据线LCD D相互绝缘并交叉限定多个 子像素001。例如，在阵列基板101的衬底基板上，可形成子像素的阵列，每个子像素可包括栅线、数据线、开关单元(例如薄膜晶体管)和像素电极。公共电极可形成在阵列基板上，也可以形成在对向基板上，从而形成不同模式的液晶显示面板，液晶面板的模式例如包括扭曲向列相(Twisted Nematic，TN)显示模式、超维场转换技术(Advanced-super Dimensional Switching，ADS)显示模式、面内开关(In-Plane Switching，IPS)显示模式等。例如，栅线被配置来为薄膜晶体管的栅极提供电信号，数据线被配置来为薄膜晶体管的源极提供电信号，像素电极可与薄膜晶体管的漏极电连接。薄膜晶体管的源极和漏极可互换。图1a中除了信号线103以及过孔102外未示出阵列基板的其它结构。
例如，如图2所示的电路结构图以及图3所示的电路时序图，以液晶显示面板100中的各像素由RGB三个子像素组成为例进行说明，电致发光显示基板300上的一条数据线OLED D1的信号对应液晶显示面板100上的三条数据线LCD D R1、LCD D G1、LCD D B1的信号，电致发光显示基板300上的另一条数据线OLED D2的信号对应液晶显示面板100上的另三条数据线LCD D R2、LCD D G2、LCD D B2的信号。
例如，在本发明实施例提供的上述显示装置中，用于分时导通液晶显示面板100上的数据线与接线端子的可控开关单元可以设置于液晶显示面板100的阵列基板101上，也可以设置于电致发光显示基板300上。例如，为了减少在液晶显示面板100中通过贯穿阵列基板101的衬底基板的过孔102的信号线103数量，各可控开关单元可设置于液晶显示面板100的阵列基板101上。这样，在阵列基板101上还包括与各像素中包含的子像素个数相同的开关控制线，以及与接线端子一一对应连接的信号引线，仅需将信号引线以及开关控制线通过过孔102引至电致发光显示基板300即可，相较于将液晶显示面板100中所有数据线通过过孔102引至电致发光显示基板300的方式，可大大降低通过贯穿阵列基板101的衬底基板的过孔102的信号线数量。
例如，本发明实施例提供的上述显示装置中的各可控开关单元可以包括：开关晶体管(例如，薄膜晶体管)。例如，开关晶体管的源极与数据线连接，开关晶体管的漏极与信号引线连接，开关晶体管的栅极与开关控制线连接。
例如图2所示，在阵列基板101上各像素由RGB三个子像素组成，则 在阵列基板101上设置三条开关控制线SW LCD R，SW LCD G，SW LCD B，以及分别与阵列基板101上的数据线LCD D R1、LCD D G1、LCD D B1、LCD D R2、LCD D G2、LCD D B2一一对应连接的作为可控开关单元的开关晶体管TR1、TG1、TB1、TR2、TG2、TB2的源极，开关晶体管TR1、TG1、TB1的漏极分别与OLED D1连接，开关晶体管TR2、TG2、TB2的漏极分别与OLED D2连接，开关晶体管TR1和TR2的栅极分别与开关控制线SW LCD R连接，开关晶体管TG1和TG2的栅极分别与开关控制线SW LCD G连接，开关晶体管TB1和TB2的栅极分别与开关控制线SW LCD B连接。
图3示出了驱动芯片400提供的开关控制线SW LCD R，SW LCD G，SW LCD B和OLED D1、OLED D2的信号，其中，OLED D1和OLED D2的信号分别提供了对应于液晶显示面板100中的三个数据线的三个梯度的电压，当开关控制线SW LCD R，SW LCD G，SW LCD B分时开启时，OLED D1和OLED D2的信号分时传入对应导通的液晶显示面板100中的数据线中，为其提供数据信号，从而实现显示。同时，OLED D1、OLED D2的信号直接传入电致发光显示基板300中的数据线，控制电致发光显示基板300的灰阶背光。
但在采用上述方式进行电致发光显示基板300的背光驱动时，由于OLED D1、OLED D2的信号在不同时刻的梯度电压不同，可能会使作为背光的电致发光显示基板300在同一时刻整体面板的发光亮度不均匀。因此，进一步地，在电致发光显示基板300的发光面上还可以设置有用于将电致发光显示基板300的出射光亮度分散均匀的光学棱镜膜301，如图1c所示。
例如，本发明实施例提供的上述显示装置中的液晶显示面板100中的像素行数和电致发光显示基板300中的像素行数可以相同，也可以不同，下面以像素行数相同为例。当在液晶显示面板100中通过过孔102引至电致发光显示基板300的信号线103包括栅线1011(如图2所示)时，或，当在电致发光显示基板300中通过过孔102引至液晶显示面板100的信号线103包括栅线3001(电致发光显示基板300中的栅线可参照图5所示，图5中还示出了电致发光显示基板300中的数据线3002)时，可以将电致发光显示基板300上的各栅线与液晶显示面板100的阵列基板101上的栅线一一对应且共同连接于驱动芯片400的同一个接线端子。
但是，采用上述方式需要将液晶显示面板100中的各条栅线逐一通过过孔102引至电致发光显示基板300上，或需要将电致发光显示基板300中的各条栅线逐一通过过孔102引至液晶显示面板100上，需要使用的过孔102数量较多，不利于实施。因此，在本发明实施例提供的上述显示装置的液晶显示面板100中和电致发光显示基板300中可以分别设置移位寄存器(GOA)，此时，在液晶显示面板100中通过过孔102引至电致发光显示基板300的信号线103不必包括数量较多的栅线，或，在电致发光显示基板300中通过过孔102引至液晶显示面板100的信号线103不必包括数量较多的栅线，仅需包括用于向移位寄存器提供电信号的信号线即可。
本发明实施例还提供了一种上述显示装置实现三维显示的方法，包括以下步骤：
在三维显示模式下，驱动芯片控制电致发光显示基板中的各像素形成交替排列的列向的发光区域和列向的黑色区域；并控制液晶显示面板中对应同一发光区域的各列像素显示不同的视点图像。人的左右眼分别位于两个视点时会接收两幅不同的图像，再由两眼的视觉汇合到大脑中成为一个像，从而产生了立体视觉，实现了亚像素级别的裸眼三维显示。在图4a中以一个发光区域对应两列像素为例示出了实现两视点的情况，其中以“1”和“2”区分不同灰阶，左眼接收到灰阶为1的画面信息，右眼接收到灰阶为2的画面信息。例如，一个发光区域可以对应三列像素即实现三视点的情况，一个发光区域也可以对应四列像素来实现四视点或两视点(相邻两个列像素组成一个视点)，以此类推。
例如，本发明实施例提供上述显示装置实现三维显示的方法中，由于通过一颗驱动芯片同时控制电致发光显示基板形成交替排列的列向的发光区域和列向的黑色区域，以及控制液晶显示面板中对应同一发光区域的各列像素显示不同的视点图像。因此，驱动芯片需要正常对电致发光显示基板和液晶显示面板中的数据线输出共用的数据线信号，从而保证液晶显示面板上的像素正常显示图像。此时，为保证电致发光显示基板中实现黑色区域，即不发光区域，如图5所示，驱动芯片400需要向电致发光显示基板300中形成黑色区域的各像素的像素电路中，与驱动晶体管DTFT的源极连接的参考信号端Vx输入低电平信号，使发光二极管OLED的两端压差为零，保证其不发 光，以实现黑色区域。在二维显示模式下，对参考信号端Vx输入高电平信号，保证发光二极管OLED正常发光。
例如，本发明实施例提供的上述显示装置在实现二维显示时，驱动芯片对于电致发光显示基板的数据线和液晶显示面板的数据线均输出信号，此时，如图4b所示，电致发光显示基板中的各像素全部发光，液晶显示面板中的各像素显示相同的灰阶，即可使人的左右眼在不同的视点观看到相同的两幅图像，从而实现二维显示。在图4b中以一个发光区域对应两列像素为例示出了实现两视点的情况，其中以“1”表示相同的灰阶。
本发明实施例提供的一种显示装置及其三维显示方法，在液晶显示面板的阵列基板上设置至少贯穿衬底基板的过孔，可使阵列基板上的信号线通过过孔从阵列基板的上表面引至下表面，经过光学胶中的导电材料与绑定于电致发光显示基板上的驱动芯片相连，这样，可以仅在电致发光显示基板上绑定驱动芯片，从而省去在液晶显示面板上设置驱动芯片。或者，可使电致发光显示基板上的信号线经过光学胶中的导电材料，通过过孔从阵列基板的下表面引至上表面与绑定于阵列基板上的驱动芯片相连，这样，可以仅在阵列基板上绑定驱动芯片，省去在电致发光显示基板上设置驱动芯片。在三维显示模式下，采用一颗驱动芯片控制电致发光显示基板中的各像素形成交替排列的列向的发光区域和列向的黑色区域，并控制液晶显示面板中对应同一发光区域的各列像素显示不同的视点图像，避免了因分别采用单独的驱动芯片进行控制带来的诸如信号同步时易出现的问题，极大地简化了驱动的复杂程度，也节省了成本。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
