 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，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发明，而非用以限制本发明。
在图中，结构相似的单元是以相同标号表示。
请参照图2，图2为本发明的面板检测装置的第一优选实施例的结构示意图。本优选实施例的面板检测装置20设置在相应的显示面板的基板15上，用于对该显示面板进行检测操作。该显示面板可为薄膜晶体管液晶显示面板（TFT-LCD，Thin Film Transistor Liquid Crystal Display）、有机发光显示面板（OLED，Organic Light Emitting Display）以及高分子发光显示面板（PLED，Polymer Light Emitting Display）等。该面板检测装置20包括数据线检测电路21以及扫描线检测电路22。
数据线检测电路21设置在显示面板的数据线驱动电路11的一侧的相对侧，其包括数据线检测开关211、数据线检测开关控制线212以及数据线检测开关数据线213。数据线检测开关211用于进行显示面板的检测操作；数据线检测开关控制线212用于控制数据线检测开关211；数据线检测开关数据线213用于输入数据线检测信号。
扫描线检测电路22设置在显示面板的扫描线驱动电路12的一侧的相对侧，其包括扫描线检测开关221、扫描线检测开关控制线222以及扫描线检测开关数据线223。扫描线检测开关221用于进行显示面板的检测操作；扫描线检测开关控制线222用于控制扫描线检测开关221；扫描线检测开关数据线223用于输入扫描线检测信号。
在本优选实施例中数据线检测开关211为第一开关管，该第一开关管的输入端与数据线检测开关数据线213连接，第一开关管的输出端与显示面板的数据线连接，第一开关管的控制端与数据线检测开关控制线212连接。
在本优选实施例中扫描线检测开关221为第三开关管，该第三开关管的输入端与扫描线检测开关数据线223连接，第三开关管的输出端与显示面板的扫描线连接，第三开关管的控制端与扫描线检测开关控制线222连接。
本优选实施例的面板检测装置20进行显示面板的测试时，通过数据线检测开关控制线212打开第一开关管，通过扫描线检测开关控制线222打开第三开关管。然后扫描线检测开关数据线223通过第三开关管向显示面板的扫描线输入检测扫描信号，数据线检测开关数据线213通过第一开关管向显示面板的数据线输入检测数据信号。这样通过检测扫描信号和检测数据信号对相应的显示单元进行点亮检测。
本优选实施例的面板检测装置20将数据线检测电路21设置在显示面板的数据线驱动电路11的一侧的相对侧，将扫描线检测电路22设置在显示面板的扫描线驱动电路12的一侧的相对侧，这样可以节省数据线驱动电路11一侧和扫描线驱动电路12一侧的走线空间，有利于显示面板的窄边框设计。此外由于对数据线驱动电路11一侧的相对侧和扫描线驱动电路12一侧的相对侧的走线空间较为充裕，因此面板检测装置20对显示面板检测完成后，不需要对面板检测装置20进行移除操作。
本优选实施例的面板检测装置在面板检测操作后不需要对面板检测装置进行移除操作，因此降低了显示面板的生产成本以及提升了显示面板的生产效率。
请参照图3，图3为本发明的面板检测装置的第二优选实施例的结构示意图。本优选实施例的面板检测装置30同样设置在相应的显示面板的基板15上，该面板检测装置30包括数据线检测电路31以及扫描线检测电路32。
数据线检测电路31设置在显示面板的数据线驱动电路11的一侧的相对侧，其包括数据线检测开关311、数据线检测开关控制线312以及数据线检测开关数据线313。扫描线检测电路32设置在显示面板的扫描线驱动电路12的一侧的相对侧，其包括扫描线检测开关321、扫描线检测开关控制线322以及扫描线检测开关数据线323。
本优选实施例的面板检测装置30与第一优选实施例的区别在于，本优选实施例的数据线检测开关311为依次串联的第一开关管314a和第二开关管314b，该第一开关管314a的输入端与数据线检测开关数据线313连接，第一开关管314a的输出端与第二开关管314b的输入端连接，第一开关管314a的控制端与数据线检测开关控制线312连接，第二开关管314b的控制端与数据线检测开关控制线312连接。第二开关管314b的输出端与显示面板的数据线连接。
本优选实施例的扫描线检测开关321为依次串联的第三开关管324a和第四开关管324b，第三开关管324a的输入端与扫描线检测开关数据线323连接，第三开关管324a的输出端与第四开关管324b的输入端连接，第三开关管324a的控制端与扫描线检测开关控制线322连接，第四开关管324b的控制端与扫描线检测开关控制线322连接，第四开关管324b的输出端与显示面板的扫描线连接。
同时本优选实施例的数据线检测开关控制线312与数据线检测开关数据线313一体化。显示面板检测完毕后，将数据线检测开关控制线312与一低电位驱动电路连接，将扫描线检测开关控制线322与一低电位驱动电路连接。如将数据线检测开关控制线312与数据线驱动电路11、扫描线驱动电路12或地线连接，以接收一低电位驱动信号；如将扫描线检测开关控制线322与数据线驱动电路11、扫描线驱动电路12或地线连接，以接收一低电位驱动信号。这里优选与数据线检测开关控制线312对应的低电位驱动电路不同于与扫描线检测开关控制线322对应的低电位驱动电路，以保证低电位驱动信号的稳定性。
本优选实施例的面板检测装置30进行显示面板的测试时，通过数据线检测开关控制线312打开第一开关管314a和第二开关管314b，通过扫描线检测开关控制线322打开第三开关管324a和第四开关管324b。然后扫描线检测开关数据线323通过第三开关管324a和第四开关管324b向显示面板的扫描线输入检测扫描信号，数据线检测开关数据线313通过第一开关管314a和第二开关管314b向显示面板的数据线输入检测数据信号。这样通过检测扫描信号和检测数据信号对相应的显示单元进行点亮检测。
由于本优选实施例的扫描线检测开关321和数据线检测开关311均采用了双开关管结构，这样即使其中的一个开关管发生漏电，另一个开关管还可以保证扫描线检测开关321和数据线检测开关311的处于闭合状态，从而大大降低了扫描线检测开关321和数据线检测开关311发生漏电导致显示面板非正常显示的风险。
同时由于数据线检测开关数据线313输出的信号均为正向偏压信号，因此可以将数据线检测开关控制线312与数据线检测开关数据线313一体化，通过数据线检测开关数据线313输出的正向偏压信号来驱动第一开关管314a和第二开关管314b。这样可以进一步减少面板检测装置30的走线。而由于扫描线检测开关数据线323输出的信号包括正向偏压信号和负向偏压信号，因此扫描线检测开关控制线322与扫描线检测开关数据线323不能进行一体化操作。
本优选实施例的面板检测装置30完成了显示面板的检测后，可将数据线检测开关控制线312（即数据线检测开关数据线313）与一低电位驱动电路连接，图3中为与扫描线驱动电路12连接，以接收一低电位驱动信号；将扫描线检测开关控制线322与一低电位驱动电路连接，图3中为与数据线驱动电路11连接，以接收一低电位驱动信号。这样显示面板在正常使用时，数据线检测开关控制线312会给第一开关管314a和第二开关管314b输入一个低电位信号，扫描线检测开关控制线322会给第三开关管324a和第四开关管324b输入一个低电位信号，以保证显示面板使用时，数据线检测开关311和扫描线检测开关321处于完全闭合状态，进一步避免的漏电现象的产生。当然这里数据线检测开关控制线312和扫描线检测开关控制线322，也可以其他方式与低电位驱动电路连接，如直接接地等。数据线检测开关控制线312和扫描线检测开关控制线322具体如何与低电位驱动电路连接的方式并不限制本发明的保护范围。
本优选实施例的数据线检测开关311和扫描线检测开关321也可为三个依次串联的开关管，即三开关管结构。这样的数据线检测开关311和扫描线检测开关321的结构可以进一步加强防止漏电的效果，但是较多的开关管会占用较多的空间以及增加制作成本，因此可根据用户的实际需要设计数据线检测开关311和扫描线检测开关321中的开关管数量。
本优选实施例的面板检测装置在第一优选实施例的基础上，通过双开关管等设置进一步提高了显示面板的工作稳定性。同时通过将数据线检测开关控制线与数据线检测开关数据线一体化进一步降低了显示面板的生产成本。
本发明还提供一种显示面板，该显示面板包括基板、数据线、扫描线、数据线驱动电路、扫描线驱动电路以及面板检测装置。数据线设置在基板上，扫描线也设置在基板上，该数据线驱动电路用于向数据线输入数据信号，扫描线驱动电路用于向扫描线输入扫描信号，面板检测装置用于对显示面板进行检测操作。
该面板检测装置包括数据线检测电路以及扫描线检测电路。数据线检测电路设置在显示面板的数据线驱动电路的一侧的相对侧，其包括数据线检测开关、数据线检测开关控制线以及数据线检测开关数据线。扫描线检测电路设置在显示面板的扫描线驱动电路的一侧的相对侧，其包括扫描线检测开关、扫描线检测开关控制线以及扫描线检测开关数据线。
本发明的显示面板的工作原理与上述的面板检测装置的优选实施例中的相关描述相同或相似，具体请参见上述面板检测装置的优选实施例中的相关描述。
本发明的面板检测装置及显示面板在面板检测操作后不需要对面板检测装置进行移除操作，因此降低了显示面板的生产成本以及提升了显示面板的生产效率；解决了现有的面板检测装置及显示面板的生产成本高昂以及生产效率低下的技术问题。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
