Description

液晶显示装置
技术领域
本发明涉及一种液晶显示装置，该液晶显示装置包括呈矩阵状排列的像素中所包含的开关元件和用于向该开关元件施加数据信号的数据信号线。
背景技术
液晶显示装置是具有分辨率高、薄型、轻质、低电力消耗等优异特长的平面显示装置，被广泛应用于薄型电视、计算机监视器、数字标牌等。在液晶显示装置的显示部分，使用了TFT(薄膜晶体管)等开关元件的液晶显示面板已被广泛应用。
液晶显示面板包括呈矩阵状排列的像素，该像素具有像素电极。开关元件连接至像素电极。此外，液晶显示面板包括：在行方向上并置、用于向各列的开关元件分别施加数据信号的多个第一数据信号线；设置在列方向的一端部侧、与该多个第一数据信号线各自的一端连接的源极驱动器。其中，当第一数据信号线断线时，无法由断线的部分向列方向的另一端部侧的开关元件施加数据信号。
因此，专利文献1中描述的液晶显示面板在列方向的一端部还包括多个与上述第一数据信号线重叠的第二数据信号线。在每一个源极驱动器都设有一条第二数据信号线。此外，在列方向的另一端部设置了多个与上述第一数据信号线重叠的第三数据信号线。第二数据信号线和第三数据信号线彼此连接。当第一数据信号线断线时，第二数据信号线在与断线的第一数据信号线重叠的部分熔化连接至该第一数据信号线。此外，第三数据信号线在与断线的第一数据信号线重叠的部分熔化连接至该第一数据信号线。由此从源极驱动器输出的数据信号经由第二数据信号线和第三数据信号线，被从断线部分施加至列方向的另一端部侧的开关元件。
专利文献2中记载的液晶显示装置包括：多个第三数据信号线(补偿用线)；设置于源极驱动器、向第三数据信号线供给数据信号的补偿输出部。此外，该液晶显示装置还包括控制手段，该控制手段基于地址设定，以供给与断线的第一数据信号线对应的数据的方式控制源极驱动器。由此在没有设置第二数据信号线的情形下应对第一数据信号线的多处断线。

发明内容
发明要解决的课题
然而，如专利文献1中记载的液晶显示装置那样，与一个源极驱动器连接的第二数据信号线为一条时，若连接至该一个源极驱动器的第一数据信号线两根以上断线时，将无法对全部的断线进行处理。配备了两根以上第二数据信号线时，则配置所需的空间变大，将会对液晶显示装置的窄边框化构成妨碍。
此外，在专利文献2中记载的液晶显示装置中，由于必须具备进行控制以输出对应的数据信号的控制手段及地址设定，因此构造变得复杂，另外，还存在断线的处理花费工夫的问题。
鉴于上述实际情况，完成了本公开的实施方式，其目的在于提供一种能够使液晶面板边框变窄、容易对数据信号线的断线进行补修、能够提高收率的液晶显示装置。
用于解决课题的手段
本公开的一实施方式涉及的液晶显示装置，其特征在于，具有：呈矩阵状排列的像素中所包含的开关元件；沿行方向并行设置、用于向各列的所述开关元件分别施加数据信号的多个第一数据信号线；在列方向的一端部沿列方向并行设置、与多个所述第一数据信号线重叠的两条第二数据信号线；在列方向的另一端部沿列方向并行设置、与多个所述第一数据信号线重叠、与所述第二数据信号线连接的第三数据信号线；在一个所述第二数据信号线中的与一个所述第一数据信号线重叠的部分设置、朝向另一个所述第二数据信号线突出的第一凸部；和在另一个所述第二数据信号线中的与另一个所述第一数据信号线重叠的部分设置、朝向所述一个第二数据信号线突出的第二凸部。
发明的效果
根据本公开的实施方式，提供一种能够使液晶面板窄边框化、容易对数据信号线的断线进行补修、能够提高收率的液晶显示装置。

具体实施方式
下面对本公开的实施方式基于表示该实施方式的附图进行详述。
(实施方式1)
图1是表示实施方式1涉及的液晶显示装置的构成的方块图。图1中表示的液晶显示装置在一面具有液晶面板100，像素P(图中用虚线围起来表示)沿列方向(图1的上下方向)及行方向(图1的左右方向)呈矩阵状排列。应予说明，图1中表示了像素P的一部分。
像素P具有像素电极10和经由液晶层(未示出)与该像素电极10相对的对置电极(未示出)。TFT(薄膜晶体管)11的漏电极连接至像素电极10。液晶电容由像素电极10和对置电极形成。
在像素P的各列，在像素P的行方向上的一侧设置第一源极线SL1a，在另一侧配置第一源极线SL1b。即，在液晶面板100中，多个第一源极线SL1a、SL1a、…以及第一源极线SL1b、SL1b、…在行方向上交替地并置。各列中，列方向每隔一个的像素P涉及的TFT11的源电极被连接至位于所述一侧的第一源极线SL1a。此外，各列的剩余的像素P涉及的TFT11的源电极连接至位于上述另一侧的第一源极线SL1b。即，液晶面板100是所谓的双源极面板。应予说明，图1仅显示了部分源极线。
在液晶面板100中，用于施加扫描信号的多条栅极线GL、GL、…在行方向上并置。TFT11的栅电极连接至栅极线GL，在行方向上排列的像素P涉及的TFT11的栅电极连接至同一栅极线GL。应予说明，图1仅显示了部分栅极线。
源极线SL1a和SL1b在行方向上被分成三组，为各组分别设置了源极驱动器SD。源极驱动器SD在列方向的一端侧设置于液晶面板100的外侧，在行方向上并列设置。在各源极驱动器SD连接有对应的各源极线SL1a和SL1b的一端。各源极驱动器SD将数据信号施加至所连接的第一源极线SL1a和SL1b。
液晶显示装置包括栅极驱动器GD，栅极驱动器GD在行方向的一端侧配置于液晶面板100的外侧，与各栅极线GL的一端连接。栅极驱动器GD向各栅极线GL施加扫描信号。
此外，在液晶面板100中，在列方向的一端侧，与三个源极驱动器SD分别对应地设置了两条第二源极线SL2x和SL2y。两条第二源极线SL2x和SL2y的一端经由连接配线20连接至对应的源极驱动器SD。第二源极线SL2x和SL2y各自经由绝缘膜(未示出)与连接至对应的源极驱动器SD的全部第一源极线SL1a和SL1b重叠。此外，第二源极线SL2x和SL2y各自可以与连接配线20一体地形成。
另外，在液晶面板100中，在列方向的另一端侧，并列设置了六条第三源极线SL3。第三源极线SL3经由绝缘膜(未示出)与全部的第一源极线SL1a和SL1b相重叠。另外，各源极驱动器SD经由连接配线21与两条第三源极线SL3分别相连。另外，各连接配线20和各连接配线21经由例如源极驱动器SD内设置的缓冲器(未图示)相连接，可实现数据信号的传送。再有，第三源极线和连接配线21可一体地形成。
图2是表示两条第二源极线SL2x和SL2y的示意图。图2中省略了像素P和栅极线GL的图示。第二源极线SL2x具有朝向第二源极线SL2y侧突出、在行方向上并置的多个凸部30a、30a、…。各凸部30a与第一源极线SL1a相重叠。另外，在凸部30a间，由相邻的凸部30a形成凹部30b。即，第二源极线SL2x的线宽被设计得比凹部30b中的凸部30a细。
第二源极线SL2y具有设置于与凹部30b相对的部分、插入凹部30b的凸部31a。在该凸部31a间，由相邻的凸部31a形成凹部31b。即，第二源极线SL2y的线宽被设计得比凹部31b中的凸部31a细。各凸部31a与和第一源极线SL1a相邻的第一源极线SL1b相重叠。
第二源极线SL2x的凸部30a被插入第二源极线SL2y的凹部31b，第二源极线SL2y的凸部31a被插入SL2x的凹部30b。凸部30a和31a形成第一凸部和第二凸部，凹部30b和31b形成第一凹部和第二凹部。
如图1中所示，液晶显示装置包括显示控制电路4，该显示控制电路4使用栅极驱动器GD和源极驱动器SD控制液晶面板100的显示。显示控制电路4具有：图像信号输入电路40，该图像信号输入电路40接收图像信号，该图像信号包含表示图像的图像数据；栅极驱动器控制电路41，该栅极驱动器控制电路41基于由图像信号输入电路40分离的时钟信号和同步信号来分别控制栅极驱动器GD和源极驱动器SD；以及源极驱动器控制电路42。
栅极驱动器控制电路41和源极驱动器控制电路42各自生成栅极驱动器GD和源极驱动器SD的周期性操作所需的启动信号、时钟信号、使能信号等控制信号。源极驱动器控制电路42还将由图像信号输入电路40分离的数字图像数据输出到源极驱动器SD。
栅极驱动器GD在图像数据的一帧期间内，以预定的时间差每两条地依次向各栅极线GL施加扫描信号。施加到栅极线GL的扫描信号被施加至沿行方向排列的一行的每个像素P、P、…P中所包含的TFT11的栅极。
源极驱动器SD仅累积一个水平扫描期间的由源极驱动器控制电路42提供的数字图像数据，生成表示一行的图像的数据信号。生成的数据信号被并行地分别施加至第一源极线SL1a和SL1b。
施加至第一源极线SL1a的数据信号在将扫描信号施加至对应的栅极线GL的一个水平扫描期间，经由TFT11被施加至像素电极10。另外，施加至第一源极线SL1b的数据信号在将扫描信号施加至对应的栅极线GL的一个水平扫描期间，经由TFT11被施加至像素电极10。由此将数据信号施加至在每个像素P形成的液晶电容。
此处，在液晶显示装置的制造过程中，当第一源极线SL1a和SL1b中的任一个断线时，由于存在导致显示故障的可能，因此需要修补。在这种情况下，能够通过如下所述使用第二源极线SL2x和SL2y来进行修补。
图3是使用了第二源极线SL2x和SL2y的修复程序的说明图。图3中，在一条第一源极线SL1a中产生了断线部分A，在相邻的一条第一源极线SL1b中产生了断线部分B。图3中省略了像素P和栅极线GL的图示。
产生了断线部分A的一条第一源极线SL1a和在凸部30a与该一条第一源极线SL1a重叠的第二源极线SL2x在彼此重叠的区域，利用诸如激光熔化进行熔化连接(图的阴影区域)。此外，上述一条第一源极线SL1a和与第二源极线SL2x对应的第三源极线SL3在彼此重叠的部分进行熔化连接。由此，从源极驱动器SD施加至上述一条第一源极线SL1a的数据信号，由断线部分A通过第二源极线SL2x、与该第二源极线SL2x对应的连接配线20、21以及第三源极线SL3被施加至列方向的另一端侧的像素P涉及的TFT11。
此外，产生了断线部分B的一条第一源极线SL1b和在凸部31a与该一条第一源极线SL1b重叠的第二源极线SL2y在彼此重叠的区域进行熔化连接(图的斜线区域)。上述一条第一源极线SL1b和与第二源极线SL2y对应的第三源极线SL3在彼此重叠的部分进行熔化连接。由此，从源极驱动器SD施加至第一源极线SL1b的数据信号，由断线部分B通过第二源极线SL2y、对应的连接配线20、21以及第三源极线SL3被施加至列方向的另一端侧的像素P涉及的TFT11。
根据上述结构，两条第二源极线SL2x和SL2y具有凸部30a和凸部31a，该凸部30a和凸部31a被配置在对应的凹部30b或31b内。另外，第二源极线SL2x和SL2y在凸部30a和31a处能够确保与第一源极线SL1a和SL1b熔融连接的区域。因此，第二源极线SL2x和SL2y不必在凹部30b和31b处确保能够熔化连接的区域，可以设计得更细。另外，通过设置两条第二源极线SL2x和SL2y，从而能够应对第一源极线SL1a和SL1b内两条断线的情形。因此，可以减小液晶面板100的边框宽度，能够容易地进行第一源极线SL1a和SL1b的断线的修补，能够提高液晶显示装置的收率。
应予说明，断线部分不限于图5中所示的断线部分A和B，即使在包括第一源极线SL1a和第一源极线SL1b各一条的任意两条第一源极线SL1a和SL1b发生了断线的情形下，也可以同样地进行处理。另外，第二源极线可以是三条或更多，连接配线20、21以及第三源极线并不限于图示的条数，可以是与第二源极线对应的条数。
(实施方式2)
在实施方式2中，将第四源极线并置于第二源极线。关于实施方式2涉及的液晶显示装置的结构，对与实施方式1相同的结构标注相同的附图标记，省略其详细的说明。图4是表示两条第二源极线SL2x、SL2y以及第四源极线的示意图。在图4中，省略了像素P和栅极线GL的图示。
在实施方式2中，与实施方式1同样地，并行设置第二源极线SL2x和SL2y，进而在第二源极线SL2x和SL2y将第四源极线SL4沿列方向并行设置。另外，第四源极线SL4与和并置的第二源极线SL2x和SL2y重叠的第一源极线SL1a和SL1b相重叠。与第二源极线SL2x和SL2y同样地，液晶面板100还包括对应于第四源极线SL4的第三源极线(未图示)。与第二源极线SL2x和SL2y同样地，该第三源极线和第四源极线SL4通过未图示的配线和源极驱动器SD中的缓冲器进行连接。
图5是使用了第二源极线SL2x、SL2y以及第四源极线SL4的修补程序的说明图。图5中，在一条第一源极线SL1a产生断线部分A，在相邻的一条第一源极线SL1b产生了断线部分B。此外，在与上述一条第一源极线SL1a相邻的另一条第一源极线SL1b产生了断线部分C。
在每条产生了断线部分A和断线部分B的第一源极线SL1a和SL1b中，与实施方式1同样地，与第二源极线SL2x和SL2y熔化连接(图中斜线区域)，通过熔化连接至对应的第三源极线SL3，从而能够对断线进行修补。在产生了断线部分C的第一源极线SL1b中，通过在第四源极线SL4中与该第一源极线SL1b重叠的区域被熔化连接(图中斜线区域)，将对应的第三源极线连接，从而能够对断线进行修补。通过这种方式，第四源极线SL4与第二源极线SL2x和SL2y同样地被用于断线的修补。因此，实施方式2中，能够对第一源极线SL1a和SL1b中的三条发生了断线的情形进行处理。
通过上述构造，由于与实施方式1同样地能够将第二源极线SL2x和SL2y设计得更细，因此即使进一步配设了第四源极线SL4的情况下，也可以实现液晶显示装置的窄边框化。此外，由于两条第二源极线SL2x、SL2y与第四源极线SL4并行设置，因此能够对第一源极线SL1a和SL1b中三条断线的情形进行处理。
应予说明，断线部分不限于图5中所示的断线部分A、B和C，即使在包括第一源极线SL1a和第一源极线SL1b中至少各一条在内的任意三条第一源极线SL1a和SL1b发生了断线的情形下，也可以以相同的方式进行处理。另外，第四源极线可以是两条以上，上述配线和第三源极线也可以是与第二源极线和第四源极线的条数对应的条数。
应予说明，在上述实施方式1和实施方式2中，源极驱动器的个数不限于三个，可以是两个以下或四个以上。此外，液晶面板100不限于双源极面板。此外，凸部30a和31a可以以跨越并非一条第一源极线SL1a和SL1b而是多条第一源极线SL1a和SL1b交叠的方式形成。在这种情况下，凹部30b、31b具有与凸部30a、31a对应的大小。此外，一个凸部30a重叠的第一源极线SL1a和SL1b的数量和与该一个凸部30a相邻地配置的凸部31a重叠的第一源极线SL1a和SL1b的数量可以不同。
应认为此次公开的实施方式在所有方面都是例示，而并非限制性内容。本发明的范围不限于前文所述含义，而是由权利要求来表示，意在包括与权利要求等同的含义和范围内的所有变形。即，通过对在权利要求所示的范围内进行适当变更后获得的技术手段进行组合而获得的实施方式也包括在本发明的技术范围内。
