具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。可以理解，所有的附图都是示意性的，并且通常仅示出为了阐明本发明所必需的部分，而其他部分可能被省略或仅仅暗示。
图1为本发明实施例提供的一种显示装置100的结构示意图。如图1所示，该显示装置100可以包括时序控制器110和源极驱动器120。该时序控制器110包括多个发送单元111，而源极驱动器120包括多个接收单元121。时序控制器110中的多个发送单元111与源极驱动器120中的多个接收单元121一一对应连接。也即，多个发送单元111与多个接收单元121可以采用点对点的传输模式传输信号，例如数据信号，特别是视频信号。
示例的，该显示装置可以为：液晶面板、电子纸、有机发光二极管(Organic Light-Emitting Diode；OLED)面板、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
示例的，时序控制器110上可以设置有多个端口(port)，每个端口内可以设置有至少一个通道(lane)。也即，时序控制器110上可以设置有多个通道，且时序控制器110中的多个发送单元111与该多个通道一一对应连接。源极驱动器120可以包括多个源极驱动芯片(图1中未示出)。每个源极驱动芯片上设置有多个端口，每个端口可以包括至少一个通道。也即，源极驱动器120上可以设置有多个通道，且源极驱动器120中的多个接收单元121与该多个通道一一对应连接。进一步的，时序控制器110上设置的多个通道还与源极驱动器120上设置的多个通道通过信号线一一对应连接，从而使得时序控制器110中的多个发送单元111和源极驱动器120中的多个接收单元121，分别通过时序控制器110上的端口、信号线以及源极驱动器上的端口一一对应连接。
请继续参考图1，该显示装置100还可以包括显示面板130。显示面板130上可以设置有以阵列方式排布的多个像素单元131。每个像素单元131可以包括相连接的一个薄膜晶体管和一个像素电极。多个像素单元131可以形成多列像素单元，该多列像素单元可以与源极驱动器120中的多个接收单元121一一对应连接。在一些实施例中，该显示装置100还可以包括栅极驱动电路(图1中未示出)。
在常规技术中，由于待显示图像中相邻的像素较相似，所以用于显示相邻像素的相邻两列像素单元的输入信号也较相似。因此，发送单元发送给接收单元用以驱动相邻的两列像素单元的信号会比较相似。由于显示装置中的像素单元的布设非常密集，相应地，与之对应的信号线的布设也非常密集，所以在相似的信号同时经由彼此接近的信号线传输的过程中会引起较强的信号间电磁干扰。
图2为本发明实施例提供的一种在显示装置中的信号传输方法的流程图。该信号传输方法可以应用于图1中时序控制器110的多个发送单元111中的任一发送单元111。该多个发送单元111与源极驱动器120的多个接收单元121一一对应。可以理解，该方法可以结合任何适当的硬件、软件、固件或者其组合执行。在至少一些实施例中，该方法可以通过包含在某种类型的计算机可读存储介质上的计算机可读指令形式的软件执行，该软件可以在一个或多个处理器的影响下执行。如图2所示，该信号传输方法可以包括以下步骤。
步骤201、通过发送单元中的加扰器对待发送的信号中的非标识信号进行加扰，得到加扰后的信号。因此，加扰后的信号包括：标识信号和加扰后的非标识信号。在一些实施例中，加扰器可以通过线性反馈移位寄存器来实现。为简单起见，在下文中以线性反馈移位寄存器为例来进行说明。
在实施例中，图1中的每个发送单元111均可以包括一个第一线性反馈移位寄存器，该第一线性反馈移位寄存器可以用于对信号进行加扰。在实施例中，待发送的信号是发送给源极驱动器用以驱动显示面板的信号，其可以包括标识信号和非标识信号。非标识信号可以包括用以驱动显示面板上的像素单元显示相应图像的数据信号。
图3示出了按照本发明实施例的可以由时序控制器发送给源极驱动器的一种待发送信号的示例，该待发送的信号是视频图像信号。视 频图像信号可以存储在时序控制器上。该视频图像信号可以包括在时域上连续的多帧图像信号。作为示例，图3示出了其中的五帧图像信号。每帧图像可以被划分成多个列，且每帧图像信号可以包括与时序控制器中的多个发送单元一一对应的多个列信号(图3中仅仅示出了第一帧图像信号中的多个列信号)。举例而言，列信号S(m,n)对应第m帧图像中的第n列。在一些实施例中，多帧图像信号中的相同列对应同一发送单元，由各帧相同列组成的多个列信号被安排为在时域上连续。举例而言，对应各帧图像中例如第n列的多个列信号，例如S(1,n)，S(2,n)，……S(M,n)，被安排为在时域上连续。在需要控制显示面板显示视频图像时，时序控制器中的每个发送单元均需要将分别与各帧图像中的同一列对应的多个列信号依次发送至该发送单元对应的接收单元，并经由接收单元发送给显示面板上的对应列的像素单元。由此，在实施例中，多个列信号可以被包括在某一发送单元的待发送的信号中做为非标识信号。
通过对待发送的信号，尤其是其中影响像素单元显示的非标识信号进行加扰，可以使得信号之间的差异增大。
步骤202、向对应的接收单元发送加扰后的信号。对应的接收单元采用其中的解扰器，例如第二线性反馈移位寄存器，对所接收的加扰后的信号进行解扰，得到解扰的信号。解扰的信号对应于发送单元中的加扰前的信号。
这里，举例而言，第一线性反馈移位寄存器使用的特征多项式可以包括：X 16+X 5+X 4+X 3+1、X 24+X 4+X 3+X+1或X 32+X 7+X 5+X 3+X 2+X+1。也即，第一线性反馈移位寄存器对信号X进行加扰所得到的信号为：X 16+X 5+X 4+X 3+1、X 24+X 4+X 3+X+1或X 32+X 7+X 5+X 3+X 2+X+1。可以理解，为了正确地对加扰的信号解扰，第一线性反馈移位寄存器对信号的加扰与第二线性反馈移位寄存器对信号的解扰是相逆的过程。
可以理解，在实际应用中，第一线性反馈移位寄存器的特征多项式还可以采用其他任何的适用的多阶多项式。可选地，还可以采用加权的多阶多项式。在一些实施例中，当两个发送单元的待发送的信号较相似时，可以将两个发送单元的第一线性反馈移位寄存器选择为：使得所得到的两个加扰后的信号的相差较大，即减小待发送的信号的相似度。通过把两个较相似的待发送的信号转变为两个相差较大的信 号，在传输过程中信号间的电磁干扰被减小，进而促进信号传输质量的提高。在本发明实施例提供的信号传输方法中，由于每个发送单元在发送信号之前，都采用多阶多项式对待发送的信号中的非标识信号进行了加扰，所以多个发送单元发送的多个加扰后的信号的相差较大。在同时传输多个相差较大的信号时，信号之间的电磁干扰程度较低，从而防止了接收单元接收到的信号失真，进而防止了显示面板显示的图像出现失真的现象。
图4为本发明实施例提供的另一种在显示装置中的信号传输方法的流程图。该信号传输方法可以应用于图1中的源极驱动器120的多个接收单元121中的任一接收单元121。该多个接收单元121与时序控制器110的多个发送单元111一一对应。可以理解，该方法可以结合任何适当的硬件、软件、固件或者其组合执行。在至少一些实施例中，该方法可以通过包含在某种类型的计算机可读存储介质上的计算机可读指令形式的软件执行，该软件可以在一个或多个处理器的影响下执行。如图4所示，该信号传输方法可以包括以下步骤。
步骤401、接收来自对应的发送单元的加扰后的信号。该加扰后的信号是对应的发送单元采用其中的加扰器，例如第一线性反馈移位寄存器，对待发送的信号中的非标识信号进行加扰得到的信号。加扰后的信号包括：标识信号和加扰后的非标识信号。
步骤402、通过接收单元中的解扰器，例如第二线性反馈移位寄存器对所接收的信号进行解扰，得到解扰的信号。解扰的信号被用以驱动显示面板的显示。所述解扰器对信号的解扰是加扰器对信号的加扰的逆过程。
在实施例中，第二线性反馈移位寄存器使用的与第一线性反馈移位寄存器对应的特征多项式包括：X 16+X 5+X 4+X 3+1、X 24+X 4+X 3+X+1或X 32+X 7+X 5+X 3+X 2+X+1。
在实施例中，第二线性反馈移位寄存器通过标识信号来识别所接收的信号中的加扰后的非标识信号，且对所接收的信号进行解扰包括对加扰后的非标识信号进行解扰。
在本发明实施例提供的信号传输方法中，每个接收单元所接收到的是加扰后的信号，所以所接收到的信号的相差较大。在同时接收到多个相差较大的信号时，该多个相差较大的信号之间的电磁干扰程度 较低，从而防止了接收单元接收到的信号失真，进而防止了显示面板显示的图像出现失真的现象。
图5为本发明实施例提供的又一种信号传输方法的流程图。可以理解，该方法可以结合任何适当的硬件、软件、固件或者其组合执行。在至少一些实施例中，该方法可以通过包含在某种类型的计算机可读存储介质上的计算机可读指令形式的软件执行，该软件可以在一个或多个处理器的影响下执行。如图5所示，该信号传输方法可以包括以下步骤。
步骤501、时序控制器中的发送单元采用其中的加扰器，例如第一线性反馈移位寄存器对待发送的信号中的非标识信号进行加扰，得到加扰后的信号。
在实施例中，图1中的每个发送单元111均包括一个第一线性反馈移位寄存器，该第一线性反馈移位寄存器可以用于对信号进行加扰。在实施例中，第一线性反馈移位寄存器被配置为在检测到标识信号后执行复位操作。
示例的，采用第一线性反馈移位寄存器对信号X进行加扰所得到的信号包括但不限于：X 16+X 5+X 4+X 3+1、X 24+X 4+X 3+X+1或X 32+X 7+X 5+X 3+X 2+X+1。也即，该第一线性反馈移位寄存器能够采用多阶的特征多项式对信号进行加扰。实际应用中，采用第一线性反馈移位寄存器对信号X进行加扰所得到的信号还可以为其他包含X的多阶多项式。在一些实施例中，当两个发送单元待发送的信号较相似时，其第一线性反馈移位寄存器被配置为通过采用不同的特征多项式而对其相应的待发送的信号加扰，以使得所得到的两个加扰后的信号的相似度减小，差异增大。通过减小两个待发送的信号的相似度，使得在传输过程中信号间的电磁干扰减小。
在一些实施例中，每个发送单元待发送的信号可以包括：跨多帧图像的多帧信号S(n)，其中n指示第n列。多帧信号S(n)可以是由如图3中所示的多帧图像信号中对应同一发送单元的多个列信号组成的信号。该多帧信号中的每帧信号是指各帧图像信号中对应该发送单元的列信号，其可以对应于一帧图像中的列像素。每帧信号可以包括多个行信号。要指出的是，每个发送单元对应一个接收单元，每个接收单元对应显示面板上的多列像素单元。每个发送单元待发送的信号中 的每帧信号为需要输入到显示面板上的多列像素单元的信号，而该每帧信号中的多个行信号为需要输入到该多列像素单元中的多个像素单元(也即该多列像素单元中分别对应每行的各像素单元)的信号。
图6为本发明实施例提供的一种行信号的示意图。如图6所示，该多个行信号中的每个行信号可以包括：起始标识信号K1、控制(control；ctrl)包信号、视频数据包(video data package)信号、截止标识信号K2和空(idle)包信号。起始标识信号K1用于指示每个行信号的起始位置，截止标识信号K2用于指示每个行信号的截止位置。控制包信号也可以称为行控制(control-line；ctrl-l)包信号，其包含对源极驱动器的功能控制，如时序、驱动电流等。每个发送单元待发送的信号中的控制包信号均相同。每个行信号中的标识信号可以包括：起始标识信号K1和截止标识信号K2。每个行信号中的非标识信号可以包括：控制包信号、视频数据包信号和空包信号。在本发明实施例中，发送单元在采用第一线性反馈移位寄存器对待发送的信号进行加扰时，仅仅对待发送的信号中的非标识信号，例如控制包信号和视频数据包信号进行加扰，而不对待发送的信号中的标识信号进行加扰。因此，经过第一线性反馈移位寄存器的加扰后得到的加扰后的信号可以包括：未加扰的标识信号和加扰后的非标识信号。
图7为本发明实施例提供的两个发送单元的待发送的两帧信号的示意图。如图7所示，该两个发送单元分别为：发送单元A和发送单元B。每个发送单元待发送的每帧信号包括多个行信号，由此包括对应各个行信号的多个截止标识信号K2。在实施例中，该多个截止标识信号K2中，存在至少一个特别的截止标识信号K3。与截止标识信号K2仅仅用于指示行信号的截止位置不同，该特别的截止标识信号K3不仅仅可以用于指示行信号的截止位置，还可以用于指示加扰器执行复位操作而开始对下一输入信号的加扰。在实施例中，每个发送单元待发送的信号可以被划分为多个信号分段，每个信号分段被视为一个待加扰的输入信号。每个信号分段可以包括一个或多个行信号，或者一帧或多帧信号。因此，每个发送单元待发送的信号在被加扰前可以包括：多个信号分段和至少一个特别的截止标识信号，即第一标识信号。多个信号分段在时域上依次排布，且相邻的任意两个信号分段之间存在一个第一标识信号。
在一些实施例中，图7中的每帧信号包括在时域上连续的多个行信号，且每帧信号还可以包括位于该多个行信号之后的帧结束标识信号K4，以用于指示该帧信号的结束。
返回图5，在执行步骤501时，发送单元可以采用其中的加扰器依次对待发送的信号中的每个信号分段中的非标识信号进行加扰，得到加扰后的信号。该加扰后的信号包括：加扰后的多个信号分段以及至少一个第一标识信号。加扰后的多个信号分段在时域上依次排布，且其中的相邻的任意两个信号分段之间存在一个第一标识信号。也即，发送单元在采用第一线性反馈移位寄存器对待发送的信号进行加扰的过程中，若第一线性反馈移位寄存器当前扫描到段截止标识信号，则第一线性反馈移位寄存器结束对当前信号分段的加扰，并执行复位操作。在执行完复位操作后，重新开始对段截止标识信号之后的信号分段进行扫描并加扰，从而实现对多个信号分段的分别加扰。
在实施例中，在对每个发送单元待发送的信号分段加扰的前提下，本发明实施例中还可以通过如下的方式来实现不同的加扰，即：在任意两个发送单元的待发送的信号中将第一标识信号设置在不同的时域位置(也即将任意两个发送单元的待发送的信号中的第一标识信号(例如K3)设置在不同的视频线程的位置(例如在不同行数据结束的位置))以形成不同的信号分段。如图7所示，发送单元A和发送单元B的待发送的信号中的第一标识信号K3在时域上的位置是不同的，其中发送单元A的第一标识信号K3是在图中左起第1行信号截止的位置，而发送单元B的第一标识信号K3是在图中左起第2行信号截止的位置。这使得发送单元A和发送单元B的被第一标识信号K3划分得到的多个信号分段的相似度较低。在另一实施例中，还可以在任意两个发送单元的待发送的信号中将第一标识信号设置在不同的时域位置以形成不同长度的信号分段。举例而言，发送单元A中划分的信号分段较长，而发送单元B中划分的信号分段较短。这同样使得发送单元A和发送单元B的被第一标识信号K3划分得到的多个信号分段的相似度较低。由于要被加扰的信号的相似度降低，也即区别增大，所以使得加扰后的信号的差别更大，由此而防止了在传输信号时信号间的电磁干扰。
在一些实施例中，多个接收单元与显示面板中的多列像素单元一一连接。相应地，多个发送单元通过多个对应的接收单元与显示面板 中的多列像素单元一一连接。在本发明实施例中，与任意两列相邻的像素单元所连接的两个发送单元中的加扰器，例如第一线性反馈移位寄存器被配置为对待发送的信号不同地加扰。不同地加扰可以包括由第一线性反馈移位寄存器采用不同的特征多项式来加扰待发送的信号。由于同一信号经由采用不同的特征多项式的线性反馈移位寄存器加扰后会得到不同的信号，因此，按照本公开实施例的加扰使得输入相邻两列像素单元的相似信号的相似度减小，由此在传输过程中会减小相互间的电磁干扰。
还需要说明的是，在实施例中，由于待发送信号中的标识信号还用于指示加扰的结束和开始，因此，标识信号的正确接收也是很重要的。在现有技术中，每个标识信号的比特数通常被设定为十。为了保证标识信号能够有效的被接收单元接收到，在本发明实施例中，可以将每个标识信号的比特数设置为大于十，例如可以设置每个行信号中的每个标识信号均包括连续的至少十一个比特。这样，当接收信号没接收到标识信号的前十个比特，但接收到第十个比特之后的比特时，接收单元可以根据接收到的第十个比特之后的比特，对没接收到的前十个比特进行恢复，进而确定标识信号。在另外的场景中，如果接收单元对前十个比特误判，那么接收单元能够根据第十个比特之后的比特对该前十个比特进行校正，从而准确的识别标识信号。举例而言，相关协议中定义的K code都是连续的四十比特数据，其中每十比特作为一个单元，即K1实际传输数据为K1G1G1K1。当接收数据后进行还原时，接收单元如果接收到G1G1K1这样的特征码，那么即使前十比特有误读，仍然能够根据剩余的三十比特的特征进行数据还原。这提高了标识信号的容错性。另外，由于本发明实施例中的标识信号的比特数更大，因此，本发明实施例中由更多的比特能够组合得到较多种类的标识信号，从而能够进一步的对信号传输过程中的相关信息进行标识。
示例的，每个标识信号可以包括连续的四个比特单元，且每个比特单元的比特数均为十。也即，本发明实施例中的每个标识信号可以包括四十个比特单元。当接收单元未接收到前一个或几个比特单元时，可以通过后面的比特单元，确定标识信号。
在一些实施例中，由于在标识信号中存在至少两个值不同的比特 时，接收单元能够较容易的识别出该标识信号。因此，在本发明实施例中，可以设置每个比特单元中存在至少两个值不同的比特。进一步的，每个标识信号中可以被设置为其中存在连续的6个值相同的比特。这样，接收单元在接收并识别标识信号时，可以通过判断是否接收到连续的6个值相同的比特，来确定是否接收到标识信号。
示例的，表1示出了每个发送单元待发送的信号中各个标识信号包括的四个比特单元。如表1所示，本发明实施例中的每个比特的值均为二进制数字，且为了保证每个比特单元中存在至少两个值不同的比特，可以设置四个比特单元中的两个比特单元互为非，另外两个比特单元也互为非，如：K1的四个比特单元中，比特单元(0111111010)与比特单元(1000000101)互为非，比特单元(1010101000)与比特单元(0101010111)互为非。
在一些实施例中，K1可以由在时序上依次排布的比特单元(0111111010)、比特单元(1000000101)、比特单元(1010101000)与比特单元(0101010111)组成，或者，K1可以由在时序上依次排布的比特单元(0111111010)、比特单元(0101010111)、比特单元(1010101000)与比特单元(1000000101)组成。需要说明的是，表1示出的四个比特单元的排布顺序是示例性的，而非限制性的。各标识信号所包括的四个比特单元可以采用不同于表1中示出的适用的其他排布顺序。

步骤502、发送单元对加扰后的信号进行编码，得到编码后的信号。
示例的，发送单元在发送该加扰后的信号前，为了通过降低误码率而提高信号传输的速率，还可以采用8b/10b编码(也即将8比特(bit)数据编码成10比特数据)的编码方法对该加扰后的信号进行编码，得 到编码后的信号。可选地，在编码的过程中，所有的标识信号均不会被编码，也即进行编码的信号均为非标识信号。
步骤503、发送单元向接收单元发送编码后的信号。
发送单元在得到编码后的信号后，就可以通过与对应的接收单元之间建立的通路，向对应的接收单元发送编码后的信号。需要说明的是，该多个发送单元中的每个发送单元可以并行地向各自对应的接收单元发送相应的编码后的信号。
步骤504、接收单元对接收到的编码后的信号进行解码，得到解码的信号。接收单元在接收到编码后的信号后，可以采用8b/10b解码(也即将10比特数据解码成8比特数据)的解码方法对编码后的信号进行解码，得到解码后的信号。解码后的信号对应于步骤501中得到的加扰后的信号。
步骤505、接收单元通过解扰器，例如第二线性反馈移位寄存器，对解码的信号进行解扰，得到解扰的信号，其对应于发送单元中的加扰前的信号。
接收单元可以采用第二线性反馈移位寄存器对加扰后的信号进行解扰，以得到加扰前的信号(也即待发送的信号)。这样一来，发送单元就成功的将待发送的信号发送至对应的接收单元。示例的，第一线性反馈移位寄存器对信号的加扰顺序可以与第二反馈寄存器对信号的解扰顺序相反。
在实施例中，由于每个接收单元中的第二线性反馈移位寄存器均解扰该接收单元对应的发送单元中的第一线性反馈移位寄存器加扰后的信号，因此，当两个发送单元中的第一线性反馈移位寄存器不同时，其对应的两个接收单元中的第二线性反馈移位寄存器也不同。另外，由于同一时刻不同的发送单元发送的加扰的数据会不同(源自不同的线性反馈移位寄存器)，所以从整体能量分布上看，数据能量会更加的分散，因而有消除能量峰值频谱的效果。示例的，采用本发明实施例提供的信号传输方法能够在峰值频谱处生成大约7分贝(decibel；dB)的衰减。
需要说明的是，本发明实施例提供的信号传输方法的步骤也可以根据情况进行相应增减。任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化的方法，都应涵盖在本发明的保护 范围之内。
综上所述，由于在本发明实施例提供的信号传输方法中，每个发送单元在发送信号之前，都采用多阶多项式对待发送的信号中的非标识信号进行了加扰，从而使得多个发送单元发送的多个加扰后的信号的相差较大。在同时传输多个相差较大的信号时，该多个相差较大的信号之间的电磁干扰程度较低，从而防止了接收单元接收到的信号失真，防止了显示面板显示的图像出现失真的现象。
图8为本发明实施例提供的一种发送单元的结构800的示意图。该发送单元可以用于时序控制器。时序控制器可以被实现为图1中的时序控制器110，且其包括或使用多个发送单元，图中作为示例示出了三个发送单元810 1，810 2，……，810 n。如图8所示，发送单元810 1可以包括：加扰器811 1和发送器812 1。类似地，发送单元810 2可以包括加扰器811 2和发送器812 2，以及发送单元810 n可以包括加扰器811 n和发送器812 n。加扰器811 1，811 2，……，811 n用于对待发送的信号中的非标识信号进行加扰，得到加扰后的信号。加扰后的信号包括：标识信号和加扰后的非标识信号。发送器812 1，812 2，……，812 n用于向对应的接收单元发送加扰后的信号，以便于对应的接收单元采用对应的接收单元中的解扰器，对加扰后的信号进行解扰，得到加扰前的信号。
在实施例中，加扰器811 1，811 2，……，811 n可以分别通过第一线性反馈移位寄存器实现。采用第一线性反馈移位寄存器对信号X进行加扰所得到的信号为：X 16+X 5+X 4+X 3+1、X 24+X 4+X 3+X+1或X 32+X 7+X 5+X 3+X 2+X+1。第一线性反馈移位寄存器对信号的加扰顺序与第二反馈寄存器对信号的解扰顺序相反。
在一些实施例中，待发送的信号包括：多个信号分段和至少一个在相邻的任意两信号分段之间的第一标识信号。第一标识信号用于指示线性反馈移位寄存器执行复位操作，表明线性反馈移位寄存器对当前的信号的加扰结束。加扰前的多个信号分段在时域上依次排布。在实施例中，加扰器还被配置为对每个信号分段单独地加扰。它可以用于：依次对加扰前的多个信号分段中的每个信号分段中的非标识信号进行加扰，得到加扰后的信号。加扰后的信号包括：多个加扰后的信号分段以及至少一个第一标识信号。加扰后的多个信号分段在时域上 依次排布，且加扰后的多个信号分段中的相邻的任意两信号分段之间存在一个第一标识信号。
在一些实施例中，任意两个发送单元，比如发送单元810 1，810 2，的待发送的信号中，第一标识信号的时域位置不同。这可以通过将两个待发送信号分成相同长度的信号分段，但是使信号分段的开始位置在时域上错开来实现。替换地，也可以通过将两个待发送信号分成不同长度的信号分段而使第一标识信号的位置在时域上不同。由于加扰器所加扰的各个信号不同，所以加扰后的信号差别进一步增大。由此而减小了信号间的电磁干扰。
在实施例中，多个发送单元通过对应的多个接收单元与显示面板中的多列像素单元一一连接。可以使任意两列相邻的像素单元所连接的两个发送单元中的加扰器不同，来增大加扰后的信号的差别。举例而言，图8中所示的发送单元810 1，810 2可以对应两列相邻的像素单元。由此，发送单元810 1中的加扰器811 1和发送单元810 2中的加扰器811 2可以是不同的，例如其采用不同的特征多项式。在示例中，对于同样的信号X，加扰器811 1对其加扰后所得到的信号X 1可以是：X 16+X 5+X 4+X 3+1，而加扰器811 2对其加扰后所得到的信号X 2可以是：X 24+X 4+X 3+X+1。X 1不同于X 2。因此，与同时传输两个相同的信号X相比，同时传输不同的X 1和X 2所产生的电磁干扰会大大减小。可以理解，这里所给出的加扰器的特征多项式是示例性的，而非限制性的。按照本公开实施例的加扰器还可以采用其他的适用的特征多项式。
在一些实施例中，待发送的信号包括：多帧信号。多帧信号中的每帧信号包括：多个行信号。多个行信号中的每个行信号包括：起始标识信号、控制包信号、视频数据包信号、截止标识信号和空包信号。起始标识信号用于指示每个行信号的起始位置，截止标识信号用于指示每个行信号的截止位置。在对信号进行分段的示例中，在多帧信号中的每帧信号的多个截止标识信号中，存在至少一个第一标识信号，每个第一标识信号指示信号分段的截止位置。
在一些实施例中，每个行信号中的每个标识信号均包括连续的至少十一个比特。
在一些实施例中，每个标识信号包括连续的四个比特单元，每个比特单元的比特数均为十。
在一些实施例中，每个比特单元中存在至少两个值不同的比特。
在一些实施例中，每个标识信号中存在连续6个值相同的比特。
综上所述，由于本发明实施例提供的发送单元在发送信号之前，发送单元中的加扰器，例如第一线性反馈移位寄存器都采用多阶多项式对待发送的信号中的非标识信号进行了加扰，从而使得多个发送单元中发送器发送的多个加扰后的信号的相差较大，在同时传输多个相差较大的信号时，该多个相差较大的信号之间的电磁干扰程度较低，从而防止了接收单元接收到的信号失真，防止了显示面板显示的图像出现失真的现象。
图9为本发明实施例提供的一种接收单元的结构900的示意图。该接收单元可以用于源极驱动器。源极驱动器可以被实现为图1所示的源极驱动器，其可以包括或使用多个接收单元910 1，910 2，……，910n。如图9所示，接收单元910 1可以包括接收器911 1和解扰器912 1。类似地，接收单元910 2可以包括接收器911 2和解扰器912 2，且接收单元910 n可以包括接收器911 n和解扰器912 n。接收器911 1，911 2，……，911 n用于接收来自对应的发送单元的加扰后的信号。加扰后的信号为对应的发送单元采用其中的加扰器对待发送的信号中的非标识信号进行加扰得到的信号。加扰后的信号包括：标识信号和加扰后的非标识信号。解扰器912 1，912 2，……，912 n用于对所接收的信号进行解扰，得到解扰的信号，其对应于加扰前的信号。解扰器采用与加扰器相逆的过程来对所接收的信号解扰。
在实施例中，加扰器为第一线性反馈移位寄存器，而解扰器为第二线性反馈移位寄存器。所接收到的信号是第一线性反馈移位寄存器采用以下特征多项式对信号X进行加扰所得到的信号：X 16+X 5+X 4+X 3+1、X 24+X 4+X 3+X+1或X 32+X 7+X 5+X 3+X 2+X+1。由此，第二线性反馈移位寄存器921 1，922也采用以下的与第一线性反馈移位寄存器对应的特征多项式来进行解扰：X 16+X 5+X 4+X 3+1、X 24+X 4+X 3+X+1或X 32+X 7+X 5+X 3+X 2+X+1。
在一些实施例中，所接收到的信号包括：加扰后的多个信号分段以及至少一个在相邻的任意两个信号分段之间的第一标识信号。加扰后的多个信号分段在时域上依次排布。在实施例中，解扰器912 1，912 2，……，912 n还可以用于通过第一标识信号来识别所接收到的信号 中的信号分段，且对每个信号分段单独地进行加扰。在示例中，可以对每个信号分段中的非标识信号进行解扰，以得到解扰的信号。解扰器912 1，912 2，……，912 n解扰后的信号相应地包括：解扰后的多个信号分段和至少一个第一标识信号。解扰后的多个信号分段在时域上依次排布，且相邻的任意两个信号分段之间存在一个第一标识信号。在一些实施例中，所述第一标识信号用于指示所述解扰器执行复位操作。
在一些实施例中，任意两个接收单元接收到的信号中，第一标识信号的时域位置不同。
在一些实施例中，多个接收单元与显示面板中的多列像素单元一一连接，且任意两列相邻的像素单元所连接的两个接收单元中的第二线性反馈移位寄存器不同，例如采用不同的特征多项式。
由于在本发明实施例提供的源极驱动器中，接收单元所接收到的信号是每个发送单元在发送信号之前对待发送的信号加扰后得到的加扰后的信号，因而多个接收单元所接收到的信号相差较大。在同时传输多个相差较大的信号时，该多个相差较大的信号之间的电磁干扰程度较低，从而防止了接收单元接收到的信号失真，防止了显示面板显示的图像出现失真的现象。
图2、图4和图5所示的实施例中，能够全部或部分地通过软件、硬件、固件或者其任意组合来实现。当使用软件实现时，能够全部或部分地以计算机程序产品的形式实现，所述计算机程序产品包括一个或多个计算机指令。在计算机上加载和执行所述计算机程序指令时，全部或部分地产生按照本发明实施例所述的流程或功能。所述计算机可以是可编程装置，所述计算机指令能够存储在计算机的可读存储介质中。所述计算机可读存储介质可以是计算机能够存取的任何可用介质。所述可用介质可以是磁性介质、光介质或者半导体介质等。
本发明的各种方面可以单独地、组合地或以在前文描述的实施例中没有具体讨论的各种各样的安排被使用，所以，在它的应用上不限于在以上的说明中阐述的或在附图上图示的部件的细节和安排。例如，在一个实施例中描述的某些方面可以与在其它实施例中描述的某些方面以任何方式组合。
