Description

内嵌式触摸面板的检测方法及制造方法
【技术领域】
本发明涉及触控技术领域，特别是涉及一种内嵌式触摸面板的检测方法及制造方法。
【背景技术】
相对于传统的将触摸面板设置在液晶面板上的技术，将触摸面板功能和液晶面板一体化的研究日渐盛行，于是，出现了内嵌式触摸屏。内嵌式触摸屏技术包括in-cell和on-cell两种。in-cell触摸屏技术是指将触摸面板功能嵌入到液晶像素中，而on-cell触摸屏技术是指将触摸面板功能嵌入到彩色滤光基板和偏光板之间。与on-cell触摸屏相比，in-cell触摸屏能够实现面板的更轻薄化。
在in-cell触摸屏技术中，通常采用自容式触控检测技术来检测触控点坐标，其原理为通过将多个触控电极嵌入到液晶像素中，由这些触控电极分别和地构成电容，该电容即为自电容，即触控电极对地的电容，当手指触碰到屏幕时手指的电容将会叠加到自电容上，使得自电容的电容量增加。因此，通过检测各触控电极对地的电容的电容量变化，可检测出触控点的位置。
其中，每个触控电极通过一根触控导线与触控IC连接，由触控IC实现对触控电极的扫描，进而实现对自电容的电容量变化情况的侦测，从而实现触控操作。然而，每个触控电极容易发生断路或短路的情况，如触控电极本身可能会出现断路或短路，或者与触控电极连接的触控导线也有可能发生断路或短路，从而造成无法实现触控操作，尤其是触控电极之间较为容易发生短路，如何简单快速且有效地检测出触控电极是否发生短路成为亟需解决的问题。

【具体实施方式】
下面将结合附图和具体实施方式对本发明进行详细的说明。
参阅图1，图1是内嵌式触摸面板一实施方式的结构示意图。内嵌式触摸面板1的显示技术为液晶显示技术，其触控功能采用in-cell技术实现，包括多个呈矩阵排列且相互绝缘的触控电极11，这些触控电极11可利用用于驱动内嵌式触摸面板显示的公共电极形成，每个触控电极11与一条触控导线12一一对应连接。每一列触控电极11对应的触控导线12均位于同一侧，且触控导线12沿列方向延伸出触控面板之外，以便于在后续制程中和触控IC进行连接。
参阅图2，图2是本发明内嵌式触摸面板的检测方法的一实施方式中，在触控电极正常的情况下触摸面板的亮度分布示意图。内嵌式触摸面板以4x5矩阵电极为例，对于这种具有矩阵式触控电极的内嵌式触摸面板而言，在一列触控电极11中，相邻的两条触控导线12之间较容易发生短路，而在一行触控电极中，一个触控电极11和与其相邻的一条触控导线12之间较容易发生短路。通过本实施方式的检测方法，可以简单有效地检测出相邻两个触控电极之间是否发生短路，并且也能够检测出部分发生断路的触控电极。其中，对触控电极的检测包括对触控电极本身以及对触控导线的检测。具体地，参阅图3，并结合图2，所述检测方法包括如下步骤：
步骤S301：通过对应的触控导线12-1对第一触控电极11-1提供低电平，以使第一触控电极11-1所在的显示区域呈现暗态。
本实施方式中，所有触控电极分为第一触控电极11-1和第二触控电极11-2。第一触控电极11-1和第二触控电极11-2在第一方向和第二方向上均相互交替排列，其中，第一方向和第二方向分别为列方向和行方向。如图2所示，第一触控电极11-1包括奇数行中的奇数触控电极和偶数行中的偶数触控电极，第二触控电极11-2包括奇数行中的偶数触控电极和偶数行中的奇数触控电极。每个第一触控电极11-1对应一个输入端口V1，每个第二触控电极11-2对应一个输入端口V2。
触控电极11为采用公共电极来形成，因此通过控制触控电极11的电压可以控制触摸面板是否显示以及显示的亮度。在本步骤中，所有V1端口均接低电平以对所有第一触控电极11-1提供低电平，可以是对第一触控电极11-1提供0V的低电平电压，或者V1端口接地，或者可以是使V1端口悬空，以使得第一触控电极11-1所在的显示区域不发亮，即亮度为0。
步骤S302：通过对应的触控导线12-2对第二触控电极11-2提供高电平，以使第二触控电极11-2所在的显示区域呈现亮态。
其中，步骤S301和步骤S302可以是同时进行。通过使所有的V2端口都接高电平，从而对第二触控电极11-2施加显示所需的高电平，以使第一触控电极11-2所在的显示区域发亮，以呈现亮态。
本实施方式中，通过使部分触控电极11-1所在的显示区域呈现暗态，部分触控电极11-2所在的显示区域呈现亮态，可以方便判断出在行方向上和列方向相邻的第一触控电极11-1和第二触控电极11-2是否发生短路。
在正常情况下，即第一触控电极11-1和第二触控电极11-2均没有发生故障的情况下，第一触控电极11-1所在的显示区域应是呈现暗态，而第二触控电极11-2所在的显示区域应是呈现亮态，并且由于第一触控电极11-1和第二触控电极11-2交替排列，因此，触摸面板整个显示区域所呈现的图案应是亮暗交替分布，如图2所示。如果一个第一触控电极11-1和一个第二触控电极11-2发生短路，发生短路的第一触控电极11-1将得到与第二触控电极11-2相同的高电平，其所在的显示区域将会呈现亮态。因此，根据第一触控电极11-1的亮度情况可以判断出第一触控电极11-1是否发生了短路。
因而，当驱动第一触控电极11-1所在的显示区域呈现暗态、第二触控电极11-2所在的显示区域呈现亮态时，如果其中一个第一触控电极11-1所在的显示区域呈现亮态，则说明该第一触控电极11-1和第二触控电极11-2之间发生了短路，而相邻的两个触控电极11之间较容易发生短路，因此当一个第一触控电极11-1所在的显示区域呈现亮态时可认为该第一触控电极11-1和在列方向或行方向上与其相邻的第二触控电极11-2发生了短路。
举例而言，如图4所示，当左上角的第一触控电极11-1由原本应该呈现的暗态而变为呈现亮态时，说明左上角的第一触控电极11-1可能和在列方向上与其相邻的第二触控电极11-2发生了短路，也可能是和在行方向上与其相邻的第二触控电极11-2发生了短路。当然，也有可能是与其他的第二触控电极11-2发生了短路。由此，根据第一触控电极11-1的亮度情况即可判断出触控电极之间是否发生了短路，其中，触控电极之间的短路有可能是触控导线之间的短路，也有可能是触控导线和触控电极之间的短路，还有可能是触控电极本身发生的短路。
此外，还可以根据第二触控电极11-2的亮度情况判断第二触控电极11-2是否发生了断路，即当其中一个第二触控电极11-2呈现暗态时，则说明无法对该第二触控电极11-2施加高电平，说明该第二触控电极11-2发生了断路。而当一个第二触控电极11-2呈现暗态时，将出现连续的多个呈现暗态的显示区域，因此只需观察是否存在连续的多个呈现暗态的显示区域即可判断出是否有第二触控电极11-2发生了断路。
通过上述方式，根据第一触控电极11-1的亮度情况即可判断出第一触控电极11-1是否发生了短路，还可以根据第二触控电极11-2的亮度情况判断第二触控电极11-2是否发生了断路，由此简单有效地实现对触控面板的检测。此外，当第一触控电极11-1和第二触控电极11-2发生短路时，第一触控电极11-1所在的显示区域将和第二触控电极11-2所在的显示区域一样均呈现亮态，此时将出现至少两个连续的均呈亮态的显示区域。因此，在检测的时候，只需观察是否存在连续的多个呈现亮态的显示区域即可判断是否有触控电极发生了短路，由此可直观快速地判断出触控电极是否发生故障。
触控电极的故障通常分为断路、短路以及既短路又断路三种情况。通过上述步骤S301和步骤S302，可以检测出是否有相邻的两个触控电极发生了短路，并且还可以实现对部分触控电极的断路检测。
步骤S303：通过对应的触控导线12-1对第一触控电极11-1提供高电平，以使第一触控电极11-1所在的显示区域呈现亮态。
步骤S304：通过对应的触控导线12-2对第二触控电极11-0提供低电平，以使第二触控电极所在的显示区域呈现暗态。
在完成相邻的第一触控电极11-1和第二触控电极11-2之间的短路检测之后，对第一触控电极11-1进行断路检测。当驱动第一触控电极所在的显示区域呈现亮态、第二触控电极11-2所在的显示区域呈现暗态时，在正常情况下，第一触控电极11-1所在的显示区域应全都呈现亮态，第二触控电极11-1所在的显示区域应全都呈现暗态，此时触摸面板整个显示区域所呈现的图案应是亮暗交替分布。若有一个第一触控电极11-1所对应的显示区域呈现暗态，则说明该显示区域对应的第一触控电极11-1发生断路，此时只需观察是否出现连续的多个呈现暗态的显示区域即可快速判断出是否有第一触控电极11-1发生了断路。
此外，假设在执行步骤S301和步骤S302之后，检测出左上角的第一触控电极11-1和与其相邻的第二触控电极11-2发生了短路，则在执行步骤S303和步骤S304之后，如果左上角的第一触控电极11-1所在的显示区域和其相邻的第二触控电极11-2所在的显示区域均呈现暗态，则说明该第一触控电极11-1既发生了断路又和其相邻的第二触控电极11-2发生了短路。而如果该第一触控电极11-1所在的显示区域和其相邻的一个第二触控电极11-2所在的显示区域均呈现亮态，则说明该第一触控电极11-1仅是发生了短路，且可以确定与其发生短路的第二触控电极11-2即为该呈现亮态的第二触控电极11-2。由此，可实现对触控电极断路、短路和既短路又断路的检测，且只需通过观察显示区域的亮暗情况即可快速做出判断，简单又有效。
当然，在本发明内嵌式触摸面板的检测方法的实施方式中，在执行步骤S301之前，还可以先判断是否存在断路的触控电极。具体地，在执行步骤S301之前，通过对应的触控导线12-1、12-2对第一触控电极11-1和第二触控电极11-2均提供高电平，以使第一触控电极11-1所在的显示区域和第二触控电极11-2所在的显示区域均呈现亮态，即驱动所有触控电极11所对应的显示区域均呈亮态。从而，当其中一个触控电极11所在的显示区域呈现暗态时，则说明该呈现暗态的显示区域对应的触控电极11发生断路，由此可先检测出发生断路的部分触控电极。当所有的触控电极11所在的显示区域均呈现亮态时，则进行短路和短路又断路的故障检测，即执行步骤S301-步骤S304。
在本发明内嵌式触摸面板的检测方法的其他实施方式中，第一触控电极可以是奇数行的触控电极，第二触控电极可以是偶数行的触控电极，此时第一触控电极和第二触控电极在列方向上交替排列。通过对第一触控电极和第二触控电极提供不同的电压，以使第一触控电极所在的显示区域和第二触控电极所在的显示区域具有不同的亮度，从而可以根据相邻两行触控电极各自所在的显示区域的亮度情况判断是否有触控电极发生了短路，由此快速有效地实现对触控电极的短路检测。
此外，在其他实施方式中，通过对第一触控电极和第二触控电极提供不同的电压，以使第一触控电极所在的显示区域和第二触控电极所在的显示区域具有不同的亮度的具体步骤中，可以是对第一触控电极提供能够呈现亮态的高电平电压，对第二触控电极也提供能够呈现亮态的高电平电压，通过使两个高电平电压具有一定的差异，以使得第一触控电极所在的显示区域和第二触控电极所在的显示区域具有不同的亮度，即本实施方式中，虽然第一触控电极和第二触控电极所在的显示区域均呈现亮态，但两者的亮度并不相同。驱动电压不相同，亮度也不一样，且驱动电压差异越大，亮度差异也越大。
例如，可对第一触控电极提供3V电压，对第二触控电极提供10V电压，此时第一触控电极所在的显示区域可能仅是有微弱的光线，而第二触控电极所在的显示区域可能是具有较强的光线，两者之间具有较明显差异的亮度。由于第一触控电极和第二触控电极交替排列，因此，在正常情况下，具有较小电压的触控电极所在的显示区域的亮度应都比较小，即该部分显示区域较暗，具有较大电压的触控电极所在的显示区域的亮度应都比较大，即该部分显示区域较亮，因此整个触摸面板的显示区域所呈现的亮度分布情况也应是明暗分布。当其中一个触控电极（指第一触控电极或第二触控电极）发生断路时，该触控电极所在的显示区域将呈现暗态，即该显示区域显示黑画面，没有光线射出。因此，通过观察是否存在暗态的显示区域，即可判断出是否存在发生断路的触控电极。当一个第一触控电极和一个第二触控电极发生短路时，具有较小电压的触控电极其电压将变为和具有较大电压的触控电极的电压相同或趋近于相同，此时具有较小电压的触控电极所在的显示区域的亮度将和具有较大电压的触控电极所在的显示区域相同或比较相近。由此，通过观察较小电压的触控电极所在的显示区域的亮度变化即可判断出是否存在发生短路的触控电极，即当检测到具有连续的呈现较亮的亮态的多个显示区域时则说明存在发生短路的触控电极。
在上述实施方式中，可以通过各触控电极对应的触控导线的一端口直接输入电压，参阅图5，在本发明内嵌式触摸面板的检测方法的另一实施方式中，可以通过晶体管开关来控制各触控导线和电压源的导通和断开，方便操作。具体地，如图5所示，其中第一触控电极11-1和第二触控电极11-2为在行方向和列方向上交替排列，在对触摸面板10进行检测时，首先将触控导线12和测试线路2进行连接，其中测试线路为多个TFT晶体管。具体为，使每条触控导线12通过一个TFT晶体管和信号源连接，即V1和V2端口连接信号源，第一触控电极11-1对应的所有TFT晶体管的栅极连接至同一个控制端S1，第二触控电极11-2对应的所有TFT晶体管的栅极连接至另一个控制端S2。
在开始检测时，首先，对V1端口和V2端口同时提供相同的高电平。然后，通过两个控制端S1和S2打开所有TFT晶体管，从而对所有触控电极11施加相同的高电平，以使所有触控电极11分别所在的显示区域呈现亮态。其中，当其中一个触控电极11所在的显示区域呈现暗态时，则说明该呈现暗态的显示区域对应的触控电极11发生了断路，由此可检测出发生断路的触控电极。在下一步中，通过控制端S1关闭第一触控电极11-1所对应的TFT晶体管，此时相当于是对第一触控电极11-1提供0V的低电平，以使第一触控电极11-1所在的显示区域呈现暗态，并保持第二触控电极11-2所对应的TFT晶体管的导通，以使第二触控电极11-2所在的显示区域保持亮态，从而可根据第一触控电极11-1所在的显示区域的亮度情况判断第一触控电极11-1是否发生了短路。之后，通过控制端S1打开第一触控电极11-1所对应的TFT晶体管，以使第一触控电极11-1所在的显示区域呈现亮态，并通过控制端S2关闭第二触控电极11-2所对应的TFT晶体管，以使第二触控电极11-2所在的显示区域呈现暗态，从而可根据第一触控电极11-1所在的显示区域的亮度情况判断出发生短路的第一触控电极11-1是否发生了断路。
通过本实施方式的检测方法，在检测过程中只需通过控制端S1和控制端S2即可方便地控制第一触控电极所在的显示区域和第二触控电极所在的显示区域的亮态或暗态，便于操作。
在完成检测后，通过裁切线C_L将测试线路2切除，再对触摸面板1进行Bonding等制程。
本发明还提供内嵌式触摸面板的制造方法的一实施方式，首先在第一基板的显示区域形成多个呈矩阵排列且相互绝缘的触控电极，以及形成与每个触控电极一一对应连接的触控导线，例如如图2所示的触摸面板1。触控导线沿第一方向延伸。然后将第二基板和第一基板的显示区域进行贴合，并对贴合后的触摸面板进行检测。其中，检测方法为上述任一实施方式的检测方法。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
