参照图2，在一实施例中，所述传输信号的数据提取方法包括：
步骤S10、在接收到传输信号时，解析所述传输信号对应的第一时钟信号，得到信号频率。
步骤S20、根据所述信号频率生成频率相同的第二时钟信号。
在现今生活中，随着通信技术越来越发达，传输信号传输的数据也越来越多。以数字电视的技术领域为例，随着液晶电视尺寸越来越大，解析度越来越高，需要传输的数据也日益增多，差分信号作为传输信号中一种高速的传输协议便得到广泛普及。但在传输信号在实际传输的过程中，由于传输走线特征阻抗的不一致性，传输信号在传输的过程中会遇到反射现象，反射回来的传输信号再与初始的时钟信号进行信号叠加，那么得到的实际的时钟信号的波形就会出现凹凸不平现象，如果这时再直接根据该时钟信号，即所述第一时钟信号去提取传输信号的数据，就可能会提取到错误的数据。
参照图3，以差分信号作为传输信号为例，由于差分信号反射会带来时钟信号波形的变化，当反射回来的差分信号再与时钟源发出的初始的时钟信号进行叠加后得到第一时钟信号，此时若根据该第一时钟信号的上升沿或者下降沿去提取差分信号的数据时，当所述第一时钟信号因为信号反射导致的波形凹陷或凸起过大时，就有可能会导致接收端对第一时钟信号的上升沿或下降沿的判断错误，并在错误的上升沿或者下降沿时去进行差分信号的数据的提取，接收端便有可能接收到错误的数据，导致出现对传输信号的数据提取不准确的问题，造成数据显示异常或噪点的出现。需要说明的是，该初始的时钟信号也可以是传输信号发送端发出的。
需要说明的是，所述第一时钟信号可以是时钟源发出的初始的时钟信号与传输信号进行信号叠加后得到的信号，也可以是传输信号发送端发出的初始的时钟信号与传输信号进行信号叠加后得到的。
为了解决传输信号的数据提取不准确的问题，本申请的方案是根据解析与传输信号对应的第一时钟信号，得到该第一时钟信号的信号频率，再根据该信号频率生成与第一时钟信号频率相等，但波形正常的第二时钟信号，并根据所述第二时钟信号提取所述传输信号的数据。其中，所述第一时钟信号为所述传输信号和时钟源发出的时钟信号进行叠加后得到的。
具体地，在接收到传输信号时，解析所述传输信号对应的第一时钟信号，得到信号频率，并根据所述信号频率生成频率相同的第二时钟信号，参见图4，可以是在数据驱动器（Data Driver）内部的时钟信号（CLK）支路上，设置一个频率判断元件，以及一个时钟信号产生元件，在终端控制数据驱动器的内部处理电路提取传输信号-Data的数据之前，在第一时钟信号-CLK经过所述频率判断元件时，先解析得到所述第一时钟信号的所述信号频率，再通过所述时钟信号产生元件生成与所述信号频率相同的所述第二时钟信号。
需要说明的是，所述解析所述传输信号对应的第一时钟信号，得到信号频率的步骤可以是通过解析所述传输信号对应的第一时钟信号，得到所述第一时钟信号中相邻两个零伏时间点之间的时间间隔，由于相邻两个零伏时间点之间的所述时间间隔等于半个时钟周期，便可根据所述时间间隔计算得到所述第一时钟信号的信号周期，然后根据所述信号周期，利用信号周期和信号频率为倒数关系，即可计算得到所述信号频率。
步骤S30、根据所述第二时钟信号提取所述传输信号的数据。
本实施例中，由于在所述第二时钟信号的生成过程中未受到传输信号的反射干扰，所以第二时钟信号的波形为正常的波形，且所述第二时钟信号是根据所述第一时钟信号的信号频率生成的，与第一时钟信号的频率相等，所以可以根据所述第二时钟信号提取所述传输信号的数据。参见图5，以传输信号为差分信号为例，根据所述第二时钟信号提取所述传输信号的数据，在所述第二时钟信号处于上升沿或者下降沿时，获取所述传输信号的与所述上升沿或者所述下降沿对应的时间点，根据所述时间点提取所述传输信号的所述数据。
在一实施例中，在接收到传输信号时，解析所述传输信号对应的第一时钟信号，得到信号频率；根据所述信号频率生成频率相同的第二时钟信号；根据所述第二时钟信号提取所述传输信号的数据。这样，通过生成与第一时钟信号频率相同，但信号波形正常的第二时钟信号，并根据第二时钟信号提取传输信号的数据，解决了传输信号的数据提取不准确的问题，提高了传输信号的数据提取的准确性。
在一实施例中，如图6所示，在上述图2至图5的实施例基础上，所述解析所述传输信号对应的第一时钟信号，得到信号频率的步骤包括：
步骤S40、解析所述传输信号对应的第一时钟信号，得到所述第一时钟信号中相邻两个零伏时间点之间的时间间隔。
步骤S41、根据所述时间间隔计算得到所述信号频率。
本实施例中，解析所述传输信号对应的第一时钟信号，得到所述第一时钟信号的零伏时间点。由于相邻两个零伏时间点之间的所述时间间隔等于半个时钟周期，在根据相邻的零伏时间点计算出时间间隔之后，便可根据所述时间间隔计算得到所述第一时钟信号的信号周期，然后根据所述信号周期，利用信号周期和信号频率为倒数关系，即可计算得到所述信号频率。
需要说明的是，由于所述第一时钟信号为时钟源发出的初始的时钟信号与传输信号进行信号叠加后得到的信号，所以也可以通过解析时钟源发出的初始的时钟信号的频率，以得到所述第一时钟信号的信号频率。
在一实施例中，解析所述传输信号对应的第一时钟信号，得到所述第一时钟信号中相邻两个零伏时间点之间的时间间隔；根据所述时间间隔计算得到所述信号频率。这样，通过解析得到所述第一时钟信号中，相邻两个零伏时间点之间的时间间隔，即可实现解析得到第一时钟信号的信号频率。
在一实施例中，如图7所示，在上述图2至图6的实施例基础上，所述根据所述时间间隔计算得到所述信号频率的步骤包括：
步骤S42、根据所述时间间隔计算得到所述第一时钟信号的信号周期。
步骤S43、根据所述信号周期计算得到所述信号频率。
本实施例中，由于相邻两个零伏时间点之间的所述时间间隔等于半个时钟周期，所以可以根据所述时间间隔计算得到所述第一时钟信号的信号周期，然后根据所述信号周期，利用信号周期和信号频率为倒数关系，即可计算得到所述信号频率。
在一实施例中，根据所述时间间隔计算得到所述第一时钟信号的信号周期；根据所述信号周期计算得到所述信号频率。这样，实现根据所述时间间隔计算得到所述信号频率。
在一实施例中，如图8所示，在上述图2至图7的实施例基础上，所述根据所述时间间隔计算得到所述信号频率的步骤之前，还包括：
步骤S44、将时长相等的所述时间间隔作为同一个所述时间间隔，并累计同一个所述时间间隔的出现次数。
步骤S45、将所述出现次数满足预设条件的所述时间间隔作为计算信号频率的所述时间间隔。
本实施例中，在根据时间间隔计算得到信号频率的步骤之前，先对得到的两个相邻零伏时间点的时间间隔进行筛选。需要说明的是，在理想状态下，各个相邻零伏时间点的时间间隔的时长均相等，为了避免将根据因为信号叠加而产生的零伏时间点计算出来的时间间隔作为计算信号频率的时间间隔，因此先对时间间隔进行筛选，或者对时间间隔进行验证。
具体地，获取预设时间内的所有时间间隔，将时长相等的所述时间间隔作为同一个所述时间间隔，并累计同一个所述时间间隔的出现次数。将所述出现次数满足预设条件的所述时间间隔作为计算信号频率的所述时间间隔，可以是将出现次数最多的所述时间间隔作为计算信号频率的所述时间间隔。需要说明的是，若没有出现因信号叠加而产生的零伏时间点，各个所述时间间隔的时长相等，因此同一个所述时间间隔也就只有一个，当然，该时间间隔也就可以直接设置为计算信号频率。
在一实施例中，将时长相等的所述时间间隔作为同一个所述时间间隔，并累计同一个所述时间间隔的出现次数；将所述出现次数满足预设条件的所述时间间隔作为计算信号频率的所述时间间隔。这样，提高了信号频率计算的准确性。
在一实施例中，如图9所示，在上述图2至图8的实施例基础上，所述根据所述第二时钟信号提取所述传输信号的数据的步骤包括：
步骤S50、在所述第二时钟信号处于上升沿或者下降沿时，获取所述传输信号的与所述上升沿或者所述下降沿对应的时间点。
步骤S51、根据所述时间点提取所述传输信号的所述数据。
本实施例中，由于在所述第二时钟信号的生成过程中未受到传输信号的反射干扰，所以第二时钟信号的波形为正常的波形，且所述第二时钟信号是根据所述第一时钟信号的信号频率生成的，与第一时钟信号的频率相等，所以可以根据所述第二时钟信号提取所述传输信号的数据。
在根据所述信号频率生成与所述第一时钟信号频率相同，但波形正常的第二时钟信号之后，获取所述第二时钟信号的上升沿和/或下降沿，在所述第二时钟信号处于上升沿或者下降沿时，获取所述传输信号的与所述上升沿或者所述下降沿对应的时间点，根据所述时间点提取所述传输信号的所述数据。
在一实施例中，在所述第二时钟信号处于上升沿或者下降沿时，获取所述传输信号的与所述上升沿或者所述下降沿对应的时间点；根据所述时间点提取所述传输信号的所述数据。这样，根据与第一时钟信号频率相同，但波形正常的第二时钟信号，提取所述传输信号的数据，提高了传输信号的数据提取的准确性。

步骤S80、根据所述数据提取时段提取所述传输信号的所述数据。
本实施例中，在数字电路中，由于上升沿为数字信号的电平从低电平跳变为高电平的那一瞬间，下降沿为数字信号的电平从高电平跳变为低电平的那一瞬间，因此，参照图11，提取传输信号的数据的方法还可以是在接收到传输信号时，解析所述第一时钟信号，得到所述第一时钟信号的零伏时间点，然后获取预设时长，根据所述零伏时间点和所述预设时长，生成以所述零伏时间点为中心时间点的数据提取时段，这样，所述数据提取时段即可包括所述第一时钟信号的上升沿和/或下降沿。然后根据所述数据提取时段提取所述传输信号的所述数据，即可提高传输信号的数据提取的准确率。

具体地，由于第一时钟信号的波形变异，因此第一时钟信号的所有的上升沿和下降沿的数量可能会比理想状态下，波形未变异的第一时钟信号的上升沿和下降沿的数量要多。由于零伏时间点的数量大致等于波形未变异的第一时钟信号的上升沿和下降沿的数量，因此，获取所述第一时钟信号的所有的上升沿和下降沿的数量值，作为第一数量值；以及所述零伏时间点的数量值，作为第二数量值；根据第一数量值和第二数量值的差值得到所述波形异常值。需要说明的是，所述预设时长可以是与所述波形异常值成反比例关系，因此，所述预设时长可以是计算所述波形异常值的倒数得到。
