本申请提出一种显示装置的驱动方法。
在本申请的第一实施例中，如图1所示，该显示装置的驱动方法包括以下步骤：
步骤S100、TCON读取存储器中存储的第一校验信息；
其中，第一校验信息存储在存储器的只读存储区中，只读存储区中的信息不可被改写，从而排除了干扰信号对第一校验信息的破坏，使第一校验信息始终保持其存入时的状态，从而实现其校验作用。
步骤S200、判断读取到的第一校验信息和TCON中存储的第二校验信息是否匹配：
第二校验信息可设置为与第一校验信息相同，在判断是否匹配的过程中，只需判断第一校验信息和第二校验信息是否相同即可。当然，第一校验信息与第二校验信息也可以不同，只要判断其是否满足预设的匹配规则即可。在第一校验信息的传输过程中，可能因干扰信号等导致第一校验信息的变化，因此，通过判断读取到的第一校验信息与第二校验信息是否匹配，可以确定TCON与存储器之间的通信是否正常。
若是，执行步骤S310、TCON读取存储器中存储的代码信息；
当读取到的第一校验信息与第二校验信息匹配时，表明TCON和存储器之间的通信正常，通信过程中不存在能够更改第一校验信息的干扰信号，此时，TCON读取存储器的可擦可编程存储区中存储的代码信息，以驱动显示装置。若否，执行步骤S320、TCON停止读取存储器中存储的存储信息。
当读取到的第一校验信息和第二校验信息不匹配时，表明TCON和存储器之间的通信异常，通信过程中存在能够更改第一校验信息的干扰信号，此时的干扰较强，代码信息存储在存储器的可擦可编程存储区中，此时若读取可擦可编程存储区中存储的代码信息，则代码信息可能被干扰信号所更改，因此，TCON停止读取存储器中存储的代码信息，以保护代码信息。当然，还可以进一步切断TCON与存储器之间的电连接，以保护存储器中的信息。
本申请技术方案中的显示装置的驱动方法，包括以下步骤：TCON读取存储器中存储的第一校验信息；判断读取到的第一校验信息和TCON中存储的第二校验信息是否匹配：若是，则TCON和存储器之间的通信正常，TCON读取存储器中存储的代码信息，此时，通信过程不会改写存储器中存储的代码信息；若否，则TCON和存储器之间的通信异常，此时，可能存在较强的干扰信号，导致存储器中存储的代码信息被改写，故TCON停止读取存储器中存储的信息，以保护存储器中的代码信息。其中，第一校验信息存储在存储器的只读存储区中，第一校验信息不能被改写，因此，即使通信异常，也不会造成第一校验信息的损坏，而代码信息存储在存储器的可擦可编程存储区中，以便针对不同的显示装置采用光学或电学手段烧录不同的代码，简化存储器的结构，提高存储器的使用效率。只读存储区只需占整个存储器空间的一小部分，以存储第一校验信息供校验，而代码信息存储在存储器的可擦可编程存储区中，以驱动TCON的运行。只读存储区和可擦可编程存储区可分别设置，即由一个只读存储器（ROM）和一个可擦可编程存储器（EPROM）相连形成，也可以由同一个存储器中的不同区域形成。本申请技术方案通过预先校验信息，以免干扰信号造成TCON中的代码信息被改写，从而提高了显示装置的可靠性。
在本申请的第二实施例中，如图2所示，TCON读取存储器中存储的信息的步骤包括：
步骤S410、TCON发送位置信息至存储器的控制区；
步骤S420、控制区定位至与位置信息对应的存储器的存储区；
步骤S430、被定位的存储区发送其中的信息至TCON；
其中，存储区包括只读存储区或可擦可编程存储区。
TCON读取存储器中存储的信息包括TCON读取存储器中存储的第一校验信息，也包括读取存储器中存储的代码信息。具体的，当显示装置启动时，TCON发送第一位置信息至存储器的控制区，控制区根据第一位置信息定位至存储器的只读存储区，只读存储区中发送其中的第一校验信息至TCON以待校验。而在校验成功时，TCON发送第二位置信息至存储器的控制区，控制区根据第二位置信息定位置存储器的可擦可编程存储区，可擦可编程存储区发送其中的代码信息至TCON，以驱动显示装置。通过存储器中的控制区实现对信息读取的控制，以使显示装置的驱动方法正常运行。
进一步的，TCON根据I2C协议读取存储器中存储的信息，I2C协议的通信过程中，只需要两根线即可在连接于总线上的器件之间传送信息，结构简单，灵活性好，便于开发。
在本申请的第三实施例中，如图3所示，在步骤S310之后，显示装置的驱动方法还包括以下步骤：
步骤S500、验证代码信息是否正确；
步骤S600、在代码信息不正确时，生成相应的提示信号；
步骤S700、根据提示信号改写可擦可编程存储区中存储的代码信息。
在本实施例中，考虑到可擦可编程存储区中的代码信息是可以被改写的，虽然步骤S100至步骤S310验证了当前状态下TCON和存储器之间的通信正常，不存在较强的干扰信号，然而，难以保证在生产过程中，存储器中的代码信息是否遭到干扰而已经被改写。因此，在读取代码信息后，验证代码信息是否正确，若代码信息不正确，生成相应的提示信号，以提醒相关人员对存储器中的代码信息进行维护，从而进一步提高驱动的可靠性。其中，代码信息的维护可根据提示信号的具体报错内容，对可擦可编程存储区中存储的代码信息进行改写。
本申请还提出一种驱动装置，如图4和图5所示，驱动装置10用于显示装置，驱动装置10包括存储器100，TCON200，微控制单元（MCU）300以及存储在MCU300上并可被MCU300执行的显示装置的驱动程序，其中，存储器100包括只读存储区110和可擦可编程存储区120，只读存储区110存储有第一校验信息以供校验，可擦可编程存储区120存储有代码信息以供驱动显示装置；TCON存储有与第一校验信息匹配的第二校验信息；MCU300与存储器和TCON电连接。
进一步的，驱动装置还包括通信总线400，通信总线连接只读存储器的控制区130与TCON，通信总线为I2C总线，以保障TCON和存储器之间根据I2C协议传输信息。
进一步的，可擦可编程存储区包括电可擦可编程存储区，电可擦可编程存储区的改写可通过施加高于正常工作电压的烧录电压实现，能够在电路中直接实现，具有结构简单，烧录方便的优点。
进一步的，如图5所示，MCU300设于TCON中，从而使驱动装置的集成化更好，以减小驱动装置所占的空间。
显示装置的驱动程序被MCU300执行时，实现如下操作：
TCON读取存储器中存储的第一校验信息；
判断读取到的第一校验信息与TCON中存储的第二校验信息是否匹配：
若是，TCON读取存储器中存储的代码信息；
若否，TCON停止读取存储器中存储的代码信息。
显示装置的驱动程序被MCU300执行时，TCON读取存储器中存储的信息的操作包括：
TCON发送位置信息至存储器的控制区；
控制区定位至与位置信息对应的存储器的存储区；
被定位的存储区发送其中的信息至TCON；
其中，存储区包括只读存储区或可擦可编程存储区。
显示装置的驱动程序被MCU300执行时，TCON根据I2C协议读取存储器中存储的信息。
显示装置的驱动程序被MCU300执行时，在TCON读取存储器中存储的代码信息的操作之后，还执行以下操作：
验证代码信息是否正确；
在代码信息不正确时，生成相应的提示信号；
根据提示信号改写可擦可编程存储区中存储的代码信息。
本申请还提出一种显示装置，例如液晶显示器（LCD）、发光二极管显示器（LED）、有机电激发光显示器(OLED) 、横向电场效应显示体(IPS) 、垂直排列液晶(VA)或其他相关的显示装置等，如图4所示，该显示装置包括驱动装置10和显示面板20，驱动装置10驱动显示面板20显示图像，该驱动装置的具体结构和显示装置的驱动方法参照上述实施例，由于本显示装置采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
