本发明的实施方式
为使本申请的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本申请进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
如图1所示，本实施例提供了一种显示面板的驱动方法，其包括以下步骤：
步骤S100：在时序控制器100中预存储点对点协议中源输出使能信号的
新增设定信息；
步骤S200：源驱动器200中的侦测模块210对源输出使能信号的默认设定信息进行代码识别；以及
步骤S300：源驱动器200中的输出模块220根据默认设定信息的侦测结果，调用并输出相对应的新增设定信息。
具体地，将对点协议中源输出使能信号的新增设定信息存储在时序控制器100相应的介质中，在正常工作过程中，源驱动器200将会对源输出使能信号的默认设定信息进行侦测，当发现当前源驱动器200中源输出使能信号的默认设定信息符合一定条件时，则会调用源输出使能信号的新增设定信息，以更改在源驱动器200中执行的默认设定信息；基于此，当更换不同厂家的驱动器时，即使不同厂家的源驱动器200中源输出使能信号的默认设定信息不相同，通过 该调整方法，也可以保证源输出使能信号执行新增设定信息，从而避免出现由于更换源驱动器200导致的COF充电时间差异。
如图2所示，在其中一个实施例中，新增设定信息包括第一新增设定信息和第二新增设定信息；默认设定信息包括默认高电平开始时间和默认高电平维持时间；当步骤S310：默认高电平开始时间和/或默认高电平维持时间为零时，执行步骤S320：输出模块220调用并输出第一新增设定信息；当步骤S310：默认高电平开始时间和默认高电平维持时间均为非零时，执行步骤S330：输出模块220调用并输出第二新增设定信息。
具体地，源输出使能信号是一个脉冲信号，用于控制源驱动器200的输出，其包括两个非常关键的参数，即高电平开始时间(TPD)和高电平维持时间(TPW)，该两个参数影响着数据的时序和液晶的充电时间，其中，高电平开始时间为该脉冲信号上升沿对应的开始时间点，高电平维持时间为该脉冲信号的上升沿与下降沿之间高电平的维持时间。源驱动器200会通过侦测TP信号的上升和下降沿来做出相应的动作。在本实施例中，新增设定信息和默认设定信息均包括有该两个参数。当S310：默认高电平开始时间和/或默认高电平维持时间为零时，即当默认高电平开始时间和默认高电平维持时间中任一数值为零或者同时为零，则通过P2P协议调用并输出第一新增设定信息，此时，源驱动器200根据第一新增设定信息输出信号；反之，源驱动器200根据第二新增设定信息输出信号。
在其中一个实施例中，第一新增设定信息包括固定新增高电平开始时间和固定新增高电平维持时间；其中，固定新增高电平开始时间为S封包；固定新增高电平维持时间为L封包；S、L均为正整数。
具体地，封包(packet)为一时间单位，与P2P数据传输的每个字节的比特数和时钟频率有关系。例如，S可以但不限于为20，L可以但不限于为100。
在其中一个实施例中，第二新增设定信息包括流动新增高电平开始时间和流动新增高电平维持时间；其中，流动新增高电平开始时间与默认高电平开始时间对应设置；流动新增高电平维持时间与默认高电平维持时间对应设置。
具体地，根据侦测出的默认高电平开始时间，来对应设置流动新增高电平开始时间，根据侦测出的默认高电平维持时间，来对应设置流动新增高电平维 持时间。
如表1中所示，在其中一个实施例中，流动新增高电平开始时间与默认高电平开始时间对应设置包括：当默认高电平开始时间不大于X封包时，流动新增高电平开始时间为Y封包；当默认高电平开始时间大于X封包时，流动新增高电平开始时间与默认高电平开始时间相同；其中，X、Y均为正整数。

表2:TPW设定
Figure PCTCN2020083099-appb-000002
具体地，X为0000 0001至0001 0100即对应十进制数据1至20时，Y为20；当X为0001 0101至1111 1111即对应十进制数据21至255时，流动新增高电平开始时间与默认高电平开始时间相同。本实施例中的数值作为举例说明，并不用于限制其具体数值。其中，TPD和TPW的数值分别由8bits的二 进制数据进行控制和调节，本实例中所示出的8bits的二进制数据是从P2P信号里解读出来的，用于定义TPD和TPW的数值。
如表2所示，在其中一个实施例中，流动新增高电平维持时间与默认高电平维持时间对应设置包括：当默认高电平维持时间不大于M封包时，流动新增高电平维持时间为N封包；当默认高电平维持时间大于M封包时，流动新增高电平维持时间与默认高电平维持时间相同；其中，M、N均为正整数。
具体地，M为0000 0001至0000 1010即对应十进制数据1至10时，N为10；M为0000 1011至1111 1111即对应十进制数据11至255时，流动新增高电平维持时间与默认高电平维持时间相同。本实施例中的数值作为举例说明，并不用于限制其具体数值。
如图3所示，在其中一个实施例中，本申请提供了一种显示面板的驱动系统，其包括：时序控制器100，预存储有点对点协议中源输出使能信号的默认设定信息和新增设定信息；和源驱动器200，与时序控制器100的输出端通过点对点协议进行连接，用于侦测并根据默认设定信息，执行新增设定信息。
具体地，时序控制器100与源驱动器200通过通信传输线(TX)连接，时序控制器100将默认设定信息读取出来并打包到P2P信号里，源驱动器200将P2P信号里的源输出使能信号的默认设定信息解读出来，源输出使能信号的默认设定信息发送到源驱动器200，源驱动器200对该默认设定信息进行侦测，以识别该默认设定信息所对应的代码，并根据代码识别的结果，通过P2P协议调用存储在时序控制器100中的新增设定信息，源驱动器200按照新增设定信息进行执行。
如图4所示，在其中一个实施例中，源驱动器200包括：侦测模块210，与时序控制器100的输出端连接，用于侦测并根据默认设定信息，输出执行指令；和输出模块220，与侦测模块210的输出端连接，用于接收并根据执行指令以输出新增设定信息。
具体地，侦测模块210对默认设定信息进行代码识别，并根据代码识别结果，发出执行指令，输出模块220根据该执行指令，通过P2P协议调用存储在时序控制器100中的新增设定信息，从而实现源驱动器200按照新增设定信息驱动液晶显示器，避免了源驱动器200按照其自身设定的源输出使能信号，驱 动液晶显示器。
在其中一个实施例中，时序控制器100包括存储单元；默认设定信息和新增设定信息预存储在存储单元中。
具体地，该存储单元可以为时序控制器100自身的存储模块或者寄存器，也可以为额外添加的存储型介质，其用于存储P2P协议中源输出使能信号的默认设定信息和新增设定信息，以在更换不同厂商提供的源驱动器200时，方便通过P2P协议进行调用新增设定信息。
在其中一个实施例中，一种存储介质，存储介质存储有多条指令，指令适于处理器进行加载，以执行上述任一实施例的显示面板的驱动方法中的步骤。
本申请提供的显示面板的驱动方法，通过预存储点对点协议中源输出使能信号的新增设定信息，并对源输出使能信号的默认设定信息进行侦测，以及根据默认设定信息的侦测结果，调用新增设定信息；在不同驱动器切换使用过程中，可以统一点对点协议中源输出使能信号的设定信息，避免不同驱动器切换使用导致的充电时间差异。
可以理解的是，对本领域普通技术人员来说，可以根据本申请的技术方案及其发明构思加以等同替换或改变，而所有这些改变或替换都应属于本申请所附的权利要求的保护范围。
