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，“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。
有源矩阵显示面板完成制造工艺时，由于工艺条件、使用的材料等多种因素的影响，作为驱动部件或开关部件的TFT器件内部尤其是有源层内存在可移动的杂散电荷，这可造成TFT漏电和翘尾现象，影响显示面板的显示质量。因此，有必要对显示面板进行老化处理以调整器件内 的杂散电荷，改善TFT器件漏电和翘尾现象。
对于使用TFT的显示面板的一种老化方法是在将显示面板点亮的过程中对TFT器件施加大的栅极偏压，但是这种做法容易灼伤TFT器件，并且由于不同TFT器件的位置所导致的不同的压降及制造工艺、使用的材料等存在差异，难以对该显示面板得到均匀的老化效果，这样仍会导致显示面板发光不均匀。
本公开的实施例提供一种用于显示面板的老化装置及老化方法，该老化装置通过对显示面板提供外加电场来辅助实现老化，避免过大的偏压造成对TFT器件的灼伤，而且使得处于不同位置的TFT得到均匀的老化，并且操作简单，易于实现。该老化装置及老化方法可以用于平面显示面板，也可以用于曲面显示面板等。
第一实施例
请参阅图1，图1示出了本公开第一实施例的用于平面显示面板的老化装置10的结构示意图。老化装置10包括承载装置11、夹具12、第一电极13和第二电极14。承载装置11包括一承载面110，例如为承载台，用于承载待老化的平面显示面板20。夹具12包括多个引脚120，用于向被老化处理的平面显示面板20提供点亮信号(例如包括扫描信号、数据信号等)。第一电极13和第二电极14相对设置，用于向平面显示面板20提供电场，这里提供了垂直于待老化的平面显示面板20所在平面的电场。
在图中，从第一电极13指向第二电极14的方向被定义为第一方向D1，该第一方向的相反方向被定义为第二方向D2。
例如，夹具12可以包括多个引脚板121，该多个引脚120依次设置在引脚板121上。
例如，夹具12还可以包括升降装置122，该升降装置122与引脚板121连接，并控制引脚板121沿该第一方向和第二方向的运动，例如升降运动。
例如，第一电极13、引脚板121、承载面110和第二电极14沿第一方向依次设置，且彼此平行。
例如，第一电极13设置于基板15上。该基板15例如为平板，例 如由绝缘材料制备，该绝缘材料例如可以为塑料、陶瓷等。
例如，第二电极14设置于承载装置11与承载面110相对的表面。
例如，如图2A，第一电极13例如为板状电极，例如包括第一块状电极130及设置在第一块状电极130上的网状电极线131，网状电极线131与第一块状电极130并联，并通过引线132连接至第一电源(未示出)；如图2B，第二电极14例如为板状电极，其结构可以与第一电极13相同，例如包括第二块状电极140及设置在该第二块状电极140上的网状电极线141，该网状电极线141与该第二块状电极140并联，并通过引线142连接至第二电源(未示出)。这里，第一电源和第二电源接不同的电压，因此当分别被施加到第一电极13和第二电极14之后，可以在二者之间形成电场。
例如，老化装置10还可以包括机械手16，机械手16上设有拾取装置，用于拾取该待老化处理的平面显示面板20并将该平面显示面板20放置于承载面110上，或将该平面显示面板20从承载面110上取出。该拾取装置的一个示例为真空拾取装置，例如包括多个真空吸盘160。
例如，老化装置10还可以包括支撑板17，支撑板17位于承载装置11远离承载面110的一侧(例如图中下侧)，支撑板17上设置有多个支撑柱170，承载装置11和第二电极14上对应多个支撑柱170的位置设置有多个贯穿孔140，多个支撑柱170可沿着多个贯穿孔140沿该第一方向或第二方向运动，从而当待老化的平面显示面板20放置在这些支撑柱170的顶部时，可以降低或升高待老化处理的平面显示面板20。支撑住170的顶部可以包括例如橡胶等缓冲部。该老化装置10还可以包括驱动装置(图中未示出)，用于控制支撑柱170的运动，该驱动装置例如可以机械驱动装置、气动驱动装置或液压驱动装置；例如，机械驱动装置可以包括步进电机、螺杆等。
图3为本公开第一实施例的老化装置工作时的结构示意图，此时通过第一电源和第二电源向第一电极13和第二电极14施加不同的电压，从而在二者之间形成电场，该电场作用于放置在第一电极13和第二电极14之间的待老化的平面显示面板20上。
例如，老化装置10还可以包括腔体18，承载装置11、夹具12及 第一电极13、第二电极14均设置于该腔体18内，该腔体18可以为各种适当的形状，其包括侧壁、顶面等以界定一个封闭空间，侧壁等可以采用适当材料制备，例如塑料、玻璃、金属等，必要时还可以设置透明窗，以便于操作人员观察腔室18内部的情形。
例如，老化装置10还可以包括控制装置19、信号源191和电源192，信号源191与夹具12信号连接，控制装置191配置为控制信号源20通过夹具12向待老化处理的平面显示面板20提供点亮信号；电源192分别与第一电极13及第二电极14电连接，控制装置191配置为通过电源192向第一电极13和第二电极14施加电压。
例如，控制装置19可以包括处理器和存储器，该处理器例如是中央处理单元(CPU)或者具有数据处理能力和/或指令执行能力的其它形式的处理单元，例如，该处理器可以实现为通用处理器，并且也为单片机、微处理器、数字信号处理器、专用的图像处理芯片、或现场可编程逻辑阵列等。存储器例如可以包括易失性存储器和/或非易失性存储器，例如可以包括只读存储器(ROM)、硬盘、闪存等。相应地，该存储器可以实现为一个或多个计算机程序产品，所述计算机程序产品可以包括各种形式的计算机可读存储介质，在所述计算机可读存储介质上可以存储一个或多个计算机程序指令。处理器可以运行所述程序指令，以实现本公开实施例中控制装置的功能以及/或者其它期望的功能。例如。控制装置可以控制升降装置122进而控制引脚板121的升降运动，还可以控制支撑板17的升降运动、以及腔体18的打开和闭合等等。
例如，平面显示面板20的一面上形成器件走线，该面可以被称为图案面201，其包括多个连接点200，多个连接点200与多个引脚120一一对应，用于接收夹具12提供的点亮信号。多个引脚120位于引脚板121靠近承载面110的一侧，多个连接点200位于该显示面板朝向引脚板121的一侧。
例如，平面显示面板20为OLED显示面板。请参阅图4，该OLED显示面板包括显示区201和非显示区202，显示区201设置有多个OLED像素单元203、多条栅极线(也称扫描线或地址线)和多条数据线(也称信号线)(图未示)。每一像素单元203包括有机发光二极管和像素 电路。每个像素电路包含多个TFT以及存储电容等。
该栅极线由栅极驱动电路21(也称行驱动电路或扫描驱动电路)驱动，该数据线由数据驱动电路22(也称列驱动电路)驱动。例如，栅极驱动电路21和数据驱动电路22可以包含多个TFT。
例如，为了简化工艺、降低材料成本，栅极驱动电路21可以直接集成在该OLED显示面板20的非显示区202内，形成GOA(Gate Driver On Array)结构。
例如，平面显示面板20的多个连接点200包括栅极驱动电路21的输入端和数据驱动电路22的输入端。该点亮信号包括栅极信号Vgs、数据信号Vds等。
例如，该点亮信号还可以包括高电平信号Vdd和低电平信号Vss(例如接地信号)。
图5为本实施例涉及的OLED显示面板的一种2T1C像素电路的示意图。该2T1C像素电路包括开关晶体管T1、驱动晶体管T2以及存储电容Cs。该开关晶体管T1的栅极连接栅极线以接收扫描信号(Scan)，例如源极连接到数据线以接收数据信号(Vdata)，漏极连接到驱动晶体管T2的栅极；驱动晶体管T2的源极连接到第一电源端(Vdd，高压端)，漏极连接到OLED的正极端；存储电容Cs的一端连接到开关晶体管T1的漏极以及驱动晶体管T2的栅极，另一端连接到驱动晶体管T2的源极以及第一电源端；OLED的负极连接到第二电源端(Vss，低压端)，例如接地。该2T1C像素电路的驱动方式是将像素的明暗(灰阶)经由两个TFT和存储电容Cs来控制。当通过栅极线施加扫描信号Scan以开启开关晶体管T1时，数据驱动电路通过数据线送入的数据电压(Vdata)将经由开关晶体管T1对存储电容Cs充电，由此将数据电压存储在存储电容Cs中，且此存储的数据电压控制驱动晶体管T2的导通程度，由此控制流过驱动晶体管以驱动OLED发光的电流大小，即此电流决定该像素发光的灰阶。在图5所示的2T1C像素电路中，开关晶体管T1以及驱动晶体管T2可以根据需要为N型晶体管或P型晶体管，例如开关晶体管T1和驱动晶体管T2均为N型晶体管，或者开关晶体管T1为N型晶体管而驱动晶体管T2为P型晶体管。
例如，在上述2T1C像素电路的基础上或其它2T1C像素电路的基础上，为了补偿例如驱动晶体管T1的阈值漂移、电源线电阻导致的压降等，像素电路还可以进一步包括补偿电路，该补偿电路包括内部补偿电路或外部补偿电路，补偿电路可以包括晶体管、电容等。此外，根据需要，像素驱动电路还可以包括复位电路、感测电路等，由此可以得到3T1C、4T2C等形式。本公开的实施例对此不做限制。
下面将结合图1和图3对应用本公开第一实施例的老化装置10的老化方法进行说明。
将平面显示面板20放置于承载装置11上，将平面显示面板20的连接点200与夹具12的多个引脚120电连接；使得第一电极13与第二电极14之间形成电场可作用于平面显示面板20；通过多个引脚200向平面显示面板20施加点亮信号，以点亮平面显示面板20。
例如，老化工艺开始阶段，打开腔体18，机械手16的真空吸盘160拾取平面显示面板20准备送入腔体18内。
机械手16的真空吸盘160背离承载面110并作用于平面显示面板20与图案面201相对的一面202，以避免损伤图案面201上形成的器件走线。平面显示面板20上的多个连接点200背离承载面110朝向引脚板121。
如图1，在机械手16将平面显示面板20放置于承载面110之前，支撑板17沿该第二方向运动靠近承载装置11，带动支撑柱170沿着贯穿孔140运动并伸出承载面110，支撑柱170伸出承载面110的高度足以容纳机械手16伸到承载面110上的部分，从而使机械手16将平面显示面板20放置于多个支撑柱170上。
如图3，支撑板17沿第一方向运动远离承载装置11，带动支撑柱170沿着贯穿孔140运动并沿沿第一方向运动至承载面110以下，使得平面显示面板20放置于承载面110上。
在升降装置122的控制下，引脚板121沿着第一方向运动靠近平面显示面板20并与平面显示面板20接触，引脚板121上的多个引脚120与平面显示面板20上的多个连接点200接触并建立电连接。
关闭腔体18，接通电源192，使得第一电极13和第二电极14之间 产生电场E对平面显示面板20进行老化。
本公开的实施例采用外部形成的电场来代替大的栅极电压对TFT器件进行老化，调整TFT内的杂散电荷，改善TFT漏电和翘尾现象。外部电场方向包括第一方向D1和第二方向D2。例如，TFT包括顶栅结构和/或底栅结构，顶栅结构的TFT的栅电极比有源层更靠近基板，底栅结构的TFT的栅电极比有源层更远离基板。不同结构的TFT又根据杂散电荷的类型需要不同方向的老化电场。
请参阅图6，图6示出了一种对应图5像素电路的部分结构示意图，但是本公开的实施例不限于该具体结构。该电路包括开关晶体管T1、驱动晶体管T2及电容Cs。开关晶体管T1为顶栅结构，其栅电极311比有源层312更远离基板300。驱动晶体管T2为底栅结构，其栅电极321比有源层322更靠近基板300。开关晶体管T1和驱动晶体管T2均为增强型N型TFT。例如，由于制作工艺及材料等方面的原因，开关晶体管T1的有源层312在靠近栅极绝缘层313的沟道区域和驱动晶体管T2的有源层322在靠近栅极绝缘层323的沟道区域可能出现带负电的杂散电荷，这些杂散电荷会引起薄膜晶体管发生漏电和翘尾现象，影响薄膜晶体管的性能，因此需要对该驱动电路进行老化以使得该杂散电荷移动到该有源层远离沟道区域的本体区域。对于开关晶体管T1，需要施加第二方向D2的电场进行老化，对于驱动晶体管T2，则需要施加第一方向D1的电场进行老化。
因此，老化电场的方向需要涉及第一方向D1和第二方向D2，以使得每个TFT都能得到老化。第一上述使得第一电极13和第二电极14之间产生电场E可以包括：使得第一电极13和第二电极14之间产生沿该第一方向的电场，并于一段时间后改变电场方向，使得第一电极13和第二电极14之间产生沿该第二方向的电场。
接通信号源191，通过夹具12向平面显示面板20提供点亮信号。观察器件的点亮情况，如果平面显示面板20出现点亮不均匀的情况，可以对该电场的大小进行调节。
例如，可以通过改变第一电极13和所述第二电极14之间的距离，或者改变20平面显示面板位于第一电极13和第二电极14之间的位置 来改变电场的大小。
本公开的实施例通过对平面显示面板20提供电场来实现老化，避免过大的偏压造成TFT器件的灼伤，而且使得处于不同位置的TFT得到均匀的老化，并且操作简单，易于实现。
第二实施例
请参阅图7，图7为本公开第二实施例的用于平面显器件的老化装置10的结构示意图。第二实施例的老化装置与第一实施例中的老化装置结构基本相同，区别仅在于：夹具12的结构；夹具12以及老化时平面显示面板20与夹具12的位置关系。该实施例不需要支撑板。为了方便说明，本实施例中与第一实施例相同的元件采用相同的标号，以下不再赘述。
如图7，夹具12的引脚板121固定设置于承载面110上，而不需要升降装置控制引脚板121的运动。多个引脚120设置于引脚板121远离承载装置11的一侧。
应用第二实施例的老化装置老化平面显示装置的老化方法与应用第一实施例的老化装置老化平面显示装置的老化方法基本相同，区别主要包括：
如图7，老化工艺开始阶段，机械手16的真空吸盘160拾取平面显示面板20准备送入腔体18时，平面显示面板20的图案面201朝向承载面110，机械手16的真空吸盘160作用于图案面201相对的一面202，以避免损伤图案面201上形成的器件走线；
机械手16将平面显示面板20放置于引脚板121的表面，平面显示面板20上的多个连接点200与引脚板121上的多个引脚120直接接触并建立电连接；
机械手16的真空吸盘160朝向承载面110并作用于平面显示面板20与图案面201相对的一面202，以避免损伤图案面201上形成的器件走线。平面显示面板20上的多个连接点200朝向承载面110于引脚板121。
本公开的实施例通过对平面显示面板20提供电场来实现老化，避免过大的偏压造成TFT器件的灼伤，而且使得处于不同位置的TFT得到 均匀的老化，并且操作简单，易于实现。
虽然以上实施例都是以待老化的显示面板为平面显示面板为例进行说明的，但是本领域技术人员应该理解，本公开的实施例的老化装置也可以用于曲面显示面板。例如，根据待老化的曲面显示面板的形状、弯曲程度(如曲率半径)等对上述老化装置作适应的改变，如对承载面与夹具进行适应性改变，再使用上述老化方法对所述曲面显示面板进行老化。
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。
本申请要求于2017年8月25日递交的中国专利申请第201710743300.2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。
