【具体实施方式】
请参阅图1，图1是本发明具有触控功能的显示面板的结构示意图。如图1所示，显示面板10包括显示组件和触控组件，显示组件和触控组件共用公共电极11、12、13、14、21、22、23、24、31、32、33、34、41、42、43、44、51、52、53、54，公共电极11、12、13、14、21、22、23、24、31、32、33、34、41、42、43、44、51、52、53、54划分成以阵列方式排布的多个区域，每一区域内的公共电极通过一检测线路101连接至触控芯片102，其中显示面板进一步包括至少两条开关控制线路O-Vcom、E-Vcom，以预定方式控制多个区域所对应的检测线路，使得每一区域的公共电极以及相邻区域内的公共电极受不同的开关控制线路O-Vcom、E-Vcom的控制，进而在显示组件进行显示时通过至少两条开关控制线路O-Vcom、E-Vcom对多个区域内的公共电极的公共电压进行设置并检测显示组件在多个区域的显示状态来判断检测线路是否存在故障。如以4x5阵列方式排布的多个区域为例，两条开关控制线路O-Vcom、E-Vcom交错对公共电极进行控制，公共电极11、13、22、24、31、33、42、44、51、53受开关控制线路O-Vcom的控制；公共电极12、14、21、23、32、34、41、43、52、54受开关控制线路E-Vcom的控制。
在本发明实施例中，显示面板进一步包括多个开关元件103和至少一供电线路V com-IN，开关元件103分别与检测线路101对应设置，并串接于检测线路101内，检测线路进一步连接至供电线路Vcom-IN，至少两条开关控制线路O-Vcom、E-Vcom与多个开关元件103连接，进而通过至少两条开关控制线路O-Vcom、E-Vc om控制多个开关元件103的通断来控制检测线路101与供电线路Vcom-IN的连接和断开。优选地，供电线路Vcom-IN的数量为一条，开关控制线路O-Vcom、E-Vcom的数量为两条。例如，检测时开关控制线路Vcom-IN输入高电平，如果同时开关控制线路O-Vcom、E-Vcom都接高电平，所有的开关元件103打开，则公共电极全为亮态。如果同时开关控制线路O-Vcom、E-Vcom都接低电平，所有的 开关元件103关闭，则公共电极全为暗态。如果同时对开关控制线路O-Vcom施加高电平，则与开关控制线路O-Vcom连接的多个开关元件103导通，公共电极11、13、22、24、31、33、42、44、51、53为亮态。如果同时开关控制线路E-Vc om施加低电平，则与开关控制线路E-Vcom连接的多个开关元件103关断，公共电极12、14、21、23、32、34、41、43、52、54为暗态。若显示图案与无故障时图案相同，则说明没有故障发生，若显示图案与无故障时图案不符，则说明有故障发生，如此能够简单有效的实现TP线路的检测。
在本发明实施例中，多个开关元件103、开关控制线路O-Vcom、E-Vcom和供电线路Vcom-IN与触控芯片102的安装区域重叠，如图1所示。或设置于远离安装区域的公共电极的一侧，如图2所示。其中触控芯片102与开关元件103的靠近公共电极一侧的检测线路101电连接。在本发明实施例中，还可以通过设置一装置自动识别显示面板图案，检测TP线路故障，避免使用人工进行检测。
图3是本发明具有触控功能的显示面板的故障检测方法的流程示意图。显示面板包括显示组件和触控组件，显示组件和触控组件共用公共电极，公共电极划分成以阵列方式排布的多个区域，每一区域内的公共电极通过一检测线路连接至触控芯片。如图3所示，具有触控功能的显示面板的故障检测方法包括：
步骤S10：在显示组件进行显示时利用检测线路分别对多个区域内的公共电极的公共电压进行设置。
在本发明实施例中，在步骤S10之前，向供电线路Vcom-IN输入高电平，开关元件连接在供电线路与检测线路之间，由开关控制线路进行控制。如图4所示，以公共电极按4x5阵列方式排布的多个区域为例，通过供电线路Vcom-IN向公共电极提供公共电压。供电线路Vcom-IN与检测线路之间设置开关元件，由开关控制线路O-Vcom、E-Vcom进行控制。在步骤S10中，通过至少两条开关控制线路以预定方式对多个区域所对应的检测线路上的公共电压进行设置，以使得每一区域的公共电极与相邻区域内的公共电极由不同的开关控制线路进行公共电压设置。公共电极11、13、22、24、31、33、42、44、51、53受开关控制O-Vcom的控制；公共电极12、14、21、23、32、34、41、43、52、54受开关控制E-Vco m的控制。通过在向供电线路Vcom-IN输入高电平的同时，向开关控制线路O-Vc  om、E-Vcom施加不同的电平实现对多个区域内的公共电极的公共电压进行设置。
步骤S11：通过检测显示组件在多个区域的显示状态来判断检测线路是否存在故障。
在步骤S11中，在向供电线路Vcom-IN输入高电平的同时，并通过至少两条开关控制线路O-Vcom、E-Vcom对多个区域内的公共电极的公共电压进行设置后，对显示组件进行图像采集，并将采集到的图像与预设的标准图案进行比较。如果两者一致，说明多个区域所对应的检测线路无故障。如果两者不一致，说明多个区域所对应的检测线路有故障发生。
具体地，在向供电线路Vcom-IN输入高电平的同时，在至少两条开关控制线路O-Vcom、E-Vcom上施加用于控制显示组件进行亮态显示的第一电平；若检测多个区域的显示状态均为亮态显示，则多个区域所对应的检测线路无故障。其中第一电平优选为高电平。即如果同时开关控制线路O-Vcom、E-Vcom同时都接高电平，所有的开关元件打开，则公共电极全为亮态，如果同时开关控制线路O-V com、E-Vcom同时都接低电平，所有的开关元件关闭，则公共电极全为暗态。在至少两条开关控制线路O-Vcom、E-Vcom中的一者上施加用于控制显示组件进行亮态显示的第一电平，与之对应的开关元件打开，在至少两条开关控制线路O-Vcom、E-Vcom中的另一者上施加用于控制显示组件进行暗态显示的第二电平，与之对应的开关元件关闭；若施加第一电平的区域的显示状态均为亮态显示，同时施加第二电平的的区域的显示状态均为暗态显示，则多个区域所对应的检测线路无故障。其中第二电平优选为低电平。如图4所示，图a中，在向供电线路Vcom-IN输入高电平的同时，对开关控制线路O-Vcom施加高电平，对开关控制线路E-Vcom施加低电平，则与开关控制线路O-Vcom连接的多个开关元件导通，与开关控制线路E-Vcom连接的多个开关元件关断，公共电极11、13、22、24、31、33、42、44、51、53为亮态，公共电极12、14、21、23、32、34、41、43、52、54为暗态。图b中，在向供电线路Vcom-IN输入高电平的同时，对开关控制线路O-Vcom施加低电平，对开关控制线路E-Vcom施加高电平，则与开关控制线路E-Vcom连接的多个开关元件关断，与开关控制线路O-Vcom连接的多个开关 元件关断，共电极11、13、22、24、31、33、42、44、51、53为暗态，公共电极12、14、21、23、32、34、41、43、52、54为亮态。若显示图案与无故障时图案相同，则说明没有故障发生，若显示图案与无故障时图案不符，则说明有故障发生，如此能够简单有效的实现TP线路的检测。
在本发明实施例中，还可以通过设置一装置自动识别显示面板图案，检测TP线路故障，避免使用人工进行检测。
综上所述，本发明的显示面板包括显示组件和触控组件，显示组件和触控组件共用公共电极，公共电极划分成以阵列方式排布的多个区域，每一区域内的公共电极通过一检测线路连接至触控芯片，其中显示面板进一步包括至少两条开关控制线路，以预定方式控制多个区域所对应的检测线路，使得每一区域的公共电极以及相邻区域内的公共电极受不同的开关控制线路的控制，进而在显示组件进行显示时通过至少两条开关控制线路对多个区域内的公共电极的公共电压进行设置并检测显示组件在多个区域的显示状态来判断检测线路是否存在故障，能够简单有效的实现TP线路的检测。
以上所述仅为本发明的实施例，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。
