Description

显示装置及其修复方法 技术领域
本申请涉及显示领域，特别是涉及一种显示装置及其修复方法。
背景技术
薄膜晶体管显示装置(TFT-LCD，Thin Film Transistor Liquid Crystal Display)是当前平板显示的主要品种之一，已经成为了现代IT、视讯产品中重要的显示平台。薄膜晶体管显示装置主要驱动原理是，系统主板将R/G/B压缩信号、控制信号及动力通过线材与印制电路板(PCB)上的连接器(Connector)相连接，数据经过印制电路板上的时序控制芯片(TCON，Timing Controller)处理后，经印制电路板，通过源极驱动芯片(S-COF Source-Chip on Film)和栅极驱动芯片(G-COF Gate-Chip on Film)与显示区连接，从而使得显示装置获得所需的电源、信号。
实际的使用中，因为制程缺陷，可能会造成线缺陷，如数据线或扫描线中间出现断点。现有的修复方式通过设置在非显示区域的修补线(Repair Line)将数据传输至断点，因修补线比正常传输路径要长，且阻抗高，为避免修补线走线过程中的电阻电容的影响，导致输出至断点的电压较目标电压低，需要将数据线连接在印制电路板(PCB)上，并在印制电路板上增加较大驱动能力的运算放大器(OP，Operational Amplifier)增大修补线的输出推力。

具体实施方式
以下各实施例的说明是参考附加的图式，用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本申请，而非用以限制本申请。
附图和说明被认为在本质上是示出性的，而不是限制性的。在图中，结构相似的单元是以相同标号表示。另外，为了理解和便于描述，附图中示出的每个组件的尺寸和厚度是任意示出的，但是本申请不限于此。
在附图中，为了清晰起见，夸大了层、膜、面板、区域等的厚度。在附图中，为了理解和便于描述，夸大了一些层和区域的厚度。将理解的是，当例如层、膜、区域或基底的组件被称作“在”另一组件“上”时，所述组件可以直接在所述另一组件上，或者也可以存在中间组件。
另外，在说明书中，除非明确地描述为相反的，否则词语“包括”将被理解为意指包括所述组件，但是不排除任何其它组件。此外，在说明书中，“在......上”意指位于目标组件上方或者下方，而不意指必须位于基于重力方向的顶部上。
为更进一步阐述本申请为达成预定发明目的所采取的技术手段及功效，以下结合附图及具体实施例，对依据本申请提出的显示装置及其修复方法，其具体实施方式、结构、特征及其功效，详细说明如后。
图1为范例性的显示装置的修复方法示意图。一种范例性的显示装置的修复方法，所述显示装置10包括：印制电路板110，其上具有控制元件105；显示面板100，包括显示区118和布线区116；多个源极驱动芯片112及多个栅极驱动芯片114；修补线120，环设于所述显示面板100的布线区116。当数据线122存在断点A时，使得其由A到C的这段线无法显示。为解决此问题，通过激光或激光化学气相沉积等方式，连接所述数据线122与修补线120的两个交叠区域(B，C)，其中，BA段数据线通过原来的数据线传输数据，AC段数据线则通过修补线的辅助传输，使得AC段数据线通过B-C-A的传输路径传输数据。但由于B-C-A此传输路径较之其他未发生断线的数据线而言，传输路径长，并由此长距离的路径使得路径的阻抗(如包括线路电阻和相关的电容电阻)高，需要在印制电路板上设置具有高驱动能力的运算放大器，并通过所述的运算放大器增大传输电压， 以确保信号不失真。
在一些实施例中，多条断线的修复是一条断线的修复的累加，即通过多个修复模块对应修补多条断线。基于此点，实施例仅说明存在一条断线的修复方法，但非以此限制此修复方法只能修复一条断线，其亦可以修复多条断线。
图2为本申请一实施例的显示装置的修复方法示意图及图3为本申请一实施例的运算放大器与修补线的局部示意图，请同时参考图2和图3，在本申请的一实施例中，一种显示装置20，包括：印制电路板110，其上具有控制元件105；显示面板100，具有显示区118和布线区116；多个栅极驱动芯片114，设置于所述显示面板100的布线区116，并耦接多条扫描线(图未示)；多个源极驱动芯片112，设置于所述显示面板100的布线区116，并耦接多条数据线(图未示)；至少一个修复模块，设置于所述显示面板100的布线区116，所述修复模块包括：多个运算放大器130；修补线120，连接所述控制元件105及所述多个运算放大器130，其中，所述修补线120与所述扫描线及所述数据线之间存在交叠区域；其中，所述控制元件105耦接所述栅极驱动芯片114及所述源极驱动芯片112。其中，所述控制元件105提供修复信号，所述运算放大器130用以放大并传输所述修补线120所传递的所述修复信号。
在本申请的一实施例中，所述多个运算放大器130对应设置于所述源极驱动芯片112上。
在本申请的一实施例中，所述多个运算放大器130之间为串联设置，且前一个所述运算放大器130的输出端耦接后一个所述运算放大器130的输入端。
在本申请的一实施例中，所述修补线120级联所述多个运算放大器130，并使得所述修复信号于所述运算放大器130及所述修补线120上的传输为无衰减传输。
请再参考图2和图3，一种显示装置20的修复方法，包括：当检测显示装置20的数据线122存在断点A，其中，所述断点A使得所述数据线122分为第一部分BA和第二部分AC，且所述第一部分BA连接所述源极驱动芯片112，所述第二部分CA远离所述源极驱动芯片112；通过激光或激光化学气相沉积等的物理、化学方式，连接存在所述断点A的所述数据线122与修补线120之间的交叠区域(B，C)；印制电路板110上的控制元件105发出修复信号，所述修复信号由所述源极驱动芯片112传出，并通过所述修补线120及多个运算放大器130，传输到所述数据线的第一部分BA和所述第二部分CA。其中，通过所述修补线120及所述多个运算放大器130，使得所述修复信号无衰减传输到所述数据线122的第二部分CA，其传输路径为最后一个源极驱动芯片112到交叠区域C，再到断点A。
在本申请的一实施例中，所述多个运算放大器130为低驱动能力的运算放大器130，并通过串联多个运算放大器130，将修复信号传输到数据线122的第二部分CA。
图4为本申请一实施例的显示装置的修复方法示意图。请同时参考图4和图3，一种显示装置30，其与显示装置20相比，包括：多个运算放大器130，设置于所述显示面100的布线区116上，其中，如图4所示，所述多个运算放大器130设置所述多个栅极驱动芯片114之间，然不限于此，所述多个运算放大器130亦可以位于所述多个源级驱动芯片112之间。
在本申请的一实施例中，所述显示装置30的修复方法，通过设置于所述显示面板100上的多个运算放大器130，传输由所述控制元件105输出的修补信号。与显示装置20相比，显示装置30的运算放大器设置于显示面板100的布线区116上，而不是设置于所述源极驱动芯片112中，其传输路径可等效于由最后一个运算放大器130的输出端到交叠区域C，再到断点A，由于传输路径短，可以减小每个运算放大器130的负荷，以更好地传输修复信号。
图5为本申请一实施例的显示装置的修复方法示意图。请同时参考图5和图3，一种显示装置40，其与显示装置20和显示装置30相比，包括：多个运算放大器130，设置于所述显示面板100的布线区116以及源极驱动芯片112上(如图5所示)。
在本申请的一实施例中，所述显示装置40的修复方法，包括：通过设置于所述布线区116以及所述源极驱动芯片112上的多个运算放大器130，传输由所述控制元件105输出的修补信号。与显示装置20及显示装置30相比，显示装置40的运算放大器130于显示面板100上的布局配置更为周密，此设计可以更为精确地传输修复信号。另，通过多个运算放大器130，可使得所述修复信号的可调节范围更广，提高容错率。
在上述实施例中，所述显示装置(20，30，40)均为修复存在断点A的数据线122，但通过所述运算放大器130和修补线120，亦可以修复存在断点的扫描线。图6为本申请一实施例的显示装置的修复方法示意图。请同时参考图6和图3，一种显示装置50，包括：至少一个修复模块，设置于所述显示面板的布线区，所述修复模块包括：多个运算放大器130；一修补线120，连接所述控制元件105及所述多个运算放大器130，其中，所述修补线120与所述扫描线124之间存在交叠区域。其中所述多个运算放大器130设置于所述源极驱动芯片112上或设置于所述源极驱动芯片112之间。
在本申请的一实施例中，一种显示装置50的修复方法，包括：当检测显示装置50的扫描线124存在断点A，其中，所述断点A使得所述扫描线124分为第一部分BA和第二部分CA，且所述第一部分连接所述栅极驱动芯片114，所述第二部分远离所述栅极驱动芯片114；通过激光或激光化学气相沉积，连接存在所述断点A的所述扫描线124与修补线120之间的交叠区域(B，C)；控制元件105发出修复信号，所述修复信号105由栅极驱动芯片114传出，并通过所述修补线120及多个运算放大器130，传输到所述扫描线的第一部分BA和第二部分CA；其中，通过所述修补 线120及所述多个运算放大器130，扫描线的第二部分CA的等效传输路径为最后一个运算放大器130的输出端到交叠区域C，再到断点A，可使得所述修复信号无衰减传输到所述扫描线的第二部分CA。
在一些实施例中，若所述显示面板上具有多条断线(多条数据线或多条扫描线)，可以通过所述显示面板上的多个修复模块，对所述多条断线进行逐一修复，以提高显示装置的品质及显示效果。
图7为本申请一实施例的显示装置示意图。在一些实施例中，显示装置1，包括：控制元件2，显示面板3，以及修复模块4，所述修复模块4设置于显示面板3之外的布线区域，或置于源极驱动芯片中。其中，所述修复模块4还包括上述各实施例的显示装置(20，30，40，50)中所述的修复模块的技术特征。
本申请通过在源极驱动芯片112或显示面板100的布线区116上设置多个低驱动的运算放大器130，来代替一般性的外置运算放大器，以此优化显示装置(20，30，40，50)修复模块的电路设计，可以节省外置运算放大器的元件及打件费用，降低显示装置(20，30，40，50)的制造成本。
“在一些实施例中”及“在各种实施例中”等用语被重复地使用。所述用语通常不是指相同的实施例；但它也可以是指相同的实施例。“包含”、“具有”及“包括”等用词是同义词，除非其前后文意显示出其它意思。
以上所述，仅是本申请的实施例，并非对本申请作任何形式上的限制，虽然本申请已以具体实施例揭露如上，然而并非用以限定本申请，任何熟悉本专业的技术人员，在不脱离本申请技术方案范围内，当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本申请技术方案的内容，依据本申请的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本申请技术方案的范围内。
