Description

扩展频谱的方法、芯片、显示面板及可读存储介质
相关申请
本申请要求2018年12月05日申请的，申请号为201811484037.0名称为“扩展频谱的方法、芯片、显示面板及可读存储介质”的中国专利申请的优先权，在此将其全文引入作为参考。
技术领域
本申请涉及通信技术领域，尤其涉及一种扩展频谱的方法、芯片、显示面板及计算机可读存储介质。
背景技术
随着国民生活水平的提高，大尺寸，高解析度，高帧频的液晶面板愈来愈受欢迎。大尺寸液晶面板的驱动面板由TCON（Timing Controller，时序控制芯片）输出信号，并传输至数据驱动芯片（Data driver）和门驱动芯片（Gate Driver），以控制液晶面板进行驱动显示。如今，由于清晰度的提升，液晶面板的显示数据越来越庞大，为了保证在有限的时间内传送完有效数据，当TCON接收到前端系统端送来的显示数据时，经过展频模块将接收到的时钟信号分成两个时钟信号输出，由于国家对电磁辐射（EMI）有严格的限制，所以TCON输出的时钟通常都会做展频处理。
目前，对时钟信号进行展频处理时，使用的是同一个调制信号对两个时钟信号进行相同中心展频，展频后的两个时钟信号的能量集中位置相同，导致辐射能量无法进一步分散，而为了保证数据的正常传输，展频幅度又不能太大，从而导致展频的效果较差，不能满足EMI规格的情况。
。

参照图2，本申请扩展频谱的方法第一实施例，所述扩展频谱的方法包括：
步骤S10、在检测到时钟信号时，获取所述时钟信号对应的调制信号；
在一实施例中，液晶显示面板通过时序控制芯片TCON输出信号至数据驱动芯片和门驱动芯片，以供数据驱动芯片和门驱动芯片根据所述输出信号进行驱动显示。随着液晶显示面板的显示清晰度的提升，所述输出信号所携带的数据也逐渐增大，因此，会将接收到的显示数据中携带的时钟信号拆分成两个相同的时钟信号，以根据所述两个时钟信号分别控制数据驱动芯片和门驱动芯片进行驱动显示。由于两个时钟信号完全相同，因此导致电磁辐射（EMT）增大。为满足电磁辐射标准的要求，需要对所述两个时钟信号进行展频调制。
可选地，在所述步骤S10之前，还包括：
步骤S30、将第一调制信号输入反相器生成第二调制信号；
步骤S40、将所述第一调制信号以及所述第二调制信号作为各个时钟信号的所述调制信号。
在一实施例中，所述第一调制信号为信号发生器的输出信号，将第一输出信号输入反向器，以反相器的输出信号作为所述第二调制信号。然后根据第一调制信号对第一时钟信号进行向上展频，根据第二调制信号对第二时钟信号进行向下展频。或者，根据第一调制信号对第一时钟信号进行向下展频，根据第二调制信号对第二时钟信号进行向上展频。
可选地，在所述步骤S30之前，还包括：
步骤S50、获取信号发生器的输出信号，作为所述第一调制信号。
在所述TCON中，设置有信号发生器，所述信号发生器可以是三角波发生器，获取所述信号发生器的输出信号作为所述第一调制信号。
进一步地，步骤S20之前，还包括
步骤S60、获取显示数据，并根据所述显示数据获取显示时钟信号；
步骤S70、根据所述显示时钟信号生成两个所述相邻时钟信号。
在一实施例中，TCON接收前端系统发送的显示数据，根据所述显示数据可以确定对应的时装信号，进而TCON对所述时钟信号进行处理，即将所述时钟信号拆分成两个相邻的时钟信号（即两个相同的时钟信号）
当TCON将时钟信号拆分为两个相邻的时钟信号（即两个相同的时钟信号）时，将两个相邻的时钟信号分别输入两个不同的压控震荡器，并根据两个不同的调制信号，控制压控震荡器对所述时钟信号进行展频调制。
具体的，当TCON将时钟信号拆分为两个相邻的时钟信号时，获取其对应的调制信号，获取第一时钟信号的调制信号时，可以直接获取信号发生器的输出信号作为第一时钟信号的调制信号；获取第二时钟信号的调制信号时，可以将所述信号发生器的输出信号输入反向器，进而获取反相器的输出信号作为第二时钟信号的调制信号。在对时钟信号进行调制时，可以对第一时钟信号进行向上展频，对第二时钟信号进行向下展频。使得所述两个时钟信号的能力更加分散，从而降低由所述两个相邻的时钟信号产生的电磁辐射（EMT）。
所述第一调制信号设置为调制第一时钟信号，即将所述第一调制信号作为压控震荡器的激励信号，控制压控震荡器对所述第一时钟信号进行频谱扩展。
步骤S20、根据所述调制信号对所述时钟信号进行展频，其中，相邻时钟信号对应的调制信号为反相信号。
在一实施例中，根据所述调制信号对时钟信号进行展频，根据所述调制信号对时钟信号进行展频调制。所述时钟信号为两个相邻的时钟信号（即相同的时钟信号），为进步降低两个相邻的时钟信号所产生的电磁辐射，使用两个互为反向信号的调制信号对所述两个相邻的时钟信号进行调制。
可选地，所述步骤S20包括：
步骤S21、获取所述调制信号对应的压控振荡器；
在一实施例中，所述TCON可以包括两个互相独立的压控震荡器1和压控震荡器2。在确定调制信号后，获取所述调制信号对应的压控震荡器，其中，第一调制信号和第二调制信号可以分别对应压控震荡器1和压控震荡器2。
步骤S22、通过所述调制信号控制所述压控振荡器对所述时钟信号进行展频。
在一实施例中，当确定调制信号对应的压控震荡器后，以第一调制信号和第二调制信号分别作为所述压控震荡器1和压控震荡器2的激励信号，以第一时钟信号和第二时钟信号分别作为压控震荡器1和压控震荡器2的输入信号，控制压控震荡器1和压控震荡器2分别对第一时钟信号和第二时钟信号作向上展频和向下展频。
如说明书附图3所示，TCON内部信令流程，其中，CLK1和CLK2分别为第一时钟信号和第二时钟信号，T1和T2分别为信号发生器的输出信号和反相器的输出信号，所述T1和T2互为反向信号。其具体信令流程为：
1、前端系统将显示数据发送至TCON；
2、TCON根据显示数据确定时钟信号，并生成两个相邻的时钟信号CLK1和CLK2；
3、CLK1和CLK2分别作为压控振荡器1和压控震荡器2的输入信号；
4、将信号发生器的输出信号T1和反相器的输出信号T2分别作为，压控震荡器1和压控震荡器2的激励信号，即CLK1和CLK2的展频调制信号。
5、压控震荡器1和压控震荡器2分别对CLK1和CLK2进行向上展频和向下展频，输出展频后的CLK1s和CLK2s。
需要说明的是，所述信号发生器优选为三角波发生器，因此，所述T1和T2分别为三角波信号和反向三角波信号。
可选地，在所述步骤S20之后，还包括：
步骤S80、输出经过展频的所述相邻时钟信号。
在一实施例中，在所述第一时钟信号CLK1和CLK2经过展频后，生成展频后的时钟信号CLK1s和CLK2s。TCON输出CLK1s和CLK2s，以CLK1s和CLK2s分别控制数据驱动芯片和门驱动芯片。
在一实施例中，以两个互为反向信号的调制信号，控制两个独立的压控振荡器对两个相邻时钟信号进行反向展频，使得时钟信号的展频区间增大，且信号失真度不变，这样，进一步地控制了时钟信号的产生的电磁干扰。
此外，本申请实施例还提出一种芯片，所述芯片包括：信号发生器、压控振荡器、反相器、存储器、处理器及存储在所述存储器上并可在所述处理器上运行的扩展频谱程序，所述扩展频谱程序被所述处理器执行时实现如上实施例所述的扩展频谱的方法的步骤。
