具体实施方式
为使本领域的技术人员更好地理解本公开的技术方案，下面结合附图对本公开提供的一种振荡频率控制方法、系统和显示装置进行详细描述。
下面描述中的附图仅仅是本申请的一些示例或实施例，对于本领域的普通技术人员而言，在不付出创造性劳动的前提下，还可以根据这些附图将本申请应用于其他类似情景。此外，还可以理解的是，虽然这种开发过程中所作出的努力可能是复杂并且冗长的，然而对于与本申请公开的内容相关的本领域的普通技术人员而言，在本申请揭露的技术内容的基础上进行的一些设计，制造或者生产等变更只是常规的技术手段，不应当理解为本申请公开的内容不充分。
在本申请中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域普通技术人员显式地和隐式地理解的是，本申请所描述的实施例在不冲突的情况下，可以与其它实施例相结合。
除非另作定义，本申请所涉及的技术术语或者科学术语应当为本申 请所属技术领域内具有一般技能的人士所理解的通常意义。本申请所涉及的“一”、“一个”、“一种”、“该”等类似词语并不表示数量限制，可表示单数或复数。本申请所涉及的术语“包括”、“包含”、“具有”以及它们任何变形，意图在于覆盖不排他的包含；例如包含了一系列步骤或模块(单元)的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可以还包括没有列出的步骤或单元，或可以还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。本申请所涉及的“连接”、“相连”、“耦接”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电气的连接，不管是直接的还是间接的。本申请所涉及的“多个”是指两个或两个以上。“和/或”描述关联对象的关联关系，表示可以存在三种关系，例如，“A和/或B”可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
在具备有通信功能的显示装置中，一般包括有通信模块和显示驱动模块，通信模块用于实现显示装置与外部的通信；显示驱动模块(也称为“显示驱动芯片”，Display Driver IC，简称DDIC)用于为显示屏提供驱动信号以驱动显示屏；显示驱动模块内包括有至少一个振荡器(Oscillator)，振荡器用于产生显示驱动模块所需的系统时钟。
图1为本公开实施例中显示驱动模块中振荡器对通信模块产生干扰的一种示意图。图2A为振荡器所产生谐波落入通信模块的通信工作频段之内的一种示意图。图2B为振荡器所产生谐波位于通信模块的通信工作频段之外的一种示意图。如图1至图2B所示，在实际应用中发现，部分显示装置在完成整机装配后会存在通信模块2的通信质量较差的问题；通过研究发现，导致部分显示装置内通信模块2的通信质量较差的主要原因之一在于：显示驱动模块1中振荡器的振荡工作频率是在整机装配阶段完成设定且保持固定不变，在显示装置的使用过程中，振荡器工作 于所设定的振荡工作频率时会产生一些谐波，当这些谐波落入到通信模块2当前工作的通信工作频段内时由于共振会发生干扰，从而会对通信模块2发送信号和接收信号的能力产生不利影响。
由于相关技术中振荡器的是固定的，为保证通信模块2的通信质量，相关技术中往往会选择将通信模块2的通信工作频段避开振荡器所产生谐波的频率(振荡器所产生谐波始终位于通信模块2的通信工作频段之外)，即限定通信模块2工作于某些特定频段；但这种通过限定通信模块2的通信工作频段的方式，会使得通信模块2无法工作于某些通信制式，大大限制了通信模块2的性能。
为有效改善相关技术中存在的至少之一的技术问题，本公开提供了相应的解决方案。
图3为本公开实施例提供的振荡频率控制系统的一种结构框图。如图3所示，该振荡频率控制系统3可应用于显示装置，显示装置包括：通信模块2和显示驱动模块1，显示驱动模块1包括至少一个振荡器；其中，通信模块可以是嵌在显示驱动模块上或者固定在显示驱动模块的附近。显示驱动模块1可以设置在显示装置的柔性电路板(Flexible Printed Circuit，简称FPC)上。
振荡频率控制系统3包括：获取模块31、确定模块32和控制模块33。其中，获取模块31配置为获取通信模块2的当前工作信息；确定模块32配置为根据当前工作信息确定各振荡器所对应的振荡工作频率；控制模块33配置为控制各振荡器采用对应的振荡工作频率进行工作，其中各振荡器工作于对应的振荡工作频率时所产生谐波的频率位于通信模块2当前工作的通信工作频段之外。
在本公开实施例中，可以根据通信模块2的当前工作信息来对显示驱动模块1内振荡器的振荡工作频率进行调整，以使得振荡器工作时所产生谐波的频率发生改变且谐波的频率位于通信模块2当前工作的通信 工作频段之外，从而能有效避免振荡器所产生的谐波对通信模块2产生干扰的问题。
另外，通过上述调整振荡器的振荡工作频率的方式，使得通信模块2的通信工作频段不再受限，可以适用于各种不同的通信场景。
在一些实施例中，振荡频率控制系统3可以以软件的形式集成在显示驱动模块1中，即可以通过向显示驱动模块1中写入代码的形式来实现本公开中的振荡频率控制系统，该方案无需硬件结构的改变，有利于降低开发成本。
当然，本领域技术人员应该理解的是，本公开中的振荡频率控制系统3也可以是独立于显示驱动模块1而存在。
图4A为本公开实施例中振荡频率控制系统的另一种结构框图。如图4A所示，在一些实施例中，获取模块31所获取的通信模块2的当前工作信息包括：通信模块2当前工作的通信工作频段。此时，确定模块32可根据通信模块2当前工作的通信工作频段来确定各振荡器所对应的振荡工作频率。
在一些实施例中，振荡频率控制系统3还包括：第一存储模块36；第一存储模块36存储有第一对应关系数据。
表1为本公开实施例中不同通信工作频段及其对应的频率调整方案一种对应关系表。

频段2 调整方案2
频段3 调整方案4
... ...
频段m 调整方案m
第一对应关系数据可通过上述表1所示对应关系表来展示。第一对应关系数据记载有不同通信工作频段及其对应的频率调整方案，频率调整方案中记载有各振荡器所对应的振荡工作频率。确定模块32具体配置为根据第一对应关系数据确定出通信模块2当前工作的通信工作频段所对应的频率调整方案。
需要说明的是，可根据通信模块2的实际情况来进行不同通信工作频段的划分，然后通过预先实验/模拟的方式来获得各不同通信工作频段所对应的频率调整方案，仅需保持振荡器采用所确定的频率调整方案进行工作时所产生的谐波的频率位于该所确定的频率调整方案所对应的通信工作频段之外即可。
在一些实施例中，显示驱动模块1内所设置的振荡器包括第一振荡器和第二振荡器，第一振荡器的振荡工作频率记为OSC1，第二振荡器的振荡工作频率记为OSC2。作为一个示例，通信工作频段在第一频段(频段1)时，调用第一对应关系数据记载频率调整方案1，第一振荡器OSC1为151MHZ，第二振荡器OSC2为165.4MHZ；通信工作频段在第二频段(频段2)时，调用第一对应关系数据记载频率调整方案2，第一振荡器OSC1为151MHZ，第二振荡器OSC2为170.5MHZ；通信工作频段在第三频段(频段3)时，调用第一对应关系数据记载频率调整方案3，第一振荡器OSC1为148MHZ，第二振荡器OSC2为165.4MHZ；通信工作频段在第四频段(频段4)时，调用第一对应关系数据记载频率调整方案4，第一振荡器OSC1为148MHZ，第二振荡器OSC2为170.5MHZ。
在一些实施例中，通信工作频段在第一频段约943MHZ时，调用第一对应关系数据记载频率调整方案1，第一振荡器OSC1为151MHZ，第二振荡器OSC2为165.4MHZ；通信工作频段在第二频段约1800MHZ时，调用第一对应关系数据记载频率调整方案2，第一振荡器OSC1为148MHZ，第二振荡器OSC2为170.5MHZ。
在一些实施例中，通信模块2可以根据实际需要在多个不同通信工作频段进行切换(例如，通信模块2支持4G通信和5G通信，通信模块2的通信工作频段可在4G频段和5G频段之间作切换)。此时，振荡频率控制系统3还包括：频段检测模块35，频段检测模块35配置为检测通信模块2的通信工作频段是否发生变化，并在检测出通信模块2的通信工作频段发生变化时控制获取模块31获取通信模块2当前工作的通信工作频段，再通过确定模块32和控制模块33使得显示驱动模块1内的振荡器的振荡工作频率发生相应切换，以保证振荡器工作时所产生谐波的频率始终位于通信模块2当前工作的通信工作频段之外。
基于上述内容可见，通过设置上述频段检测模块35，可实现对振荡器的振荡工作频率的动态调节，以保证通信模块2在不同场景下始终能保持较佳通信质量。
图4B为本公开实施例中振荡频率控制系统的又一种结构框图。如图4B所示，在一些实施例中，振荡频率控制系统不但包括上述频段检测模块35和第一存储模块36，还包括：干扰检测模块39。

图5A为本公开实施例中振荡频率控制系统的又一种结构框图。如图 5A所示，在一些实施例中，获取模块31所获取的通信模块2的当前工作信息包括：通信模块2当前工作的通信制式。此时，确定模块32可根据通信模块2当前工作的通信制式来确定各振荡器所对应的振荡工作频率。
一般地，通信模块2的通信制式与通信模块2的通信工作频段存在一一对应关系。通信模块2当前工作的通信制式确定后，则通信模块2当前工作的通信工作频段也确定，故可以基于通信模块2当前工作的通信制式来确定各振荡器所对应的振荡工作频率。其中，通信模块2的通信制式包括但不限于：2G通信制式(例如，GSM制式、CDMA制式)、3G通信制式(例如，TD-SCDMA制式、WCDMA制式、CDMA2000制式)、WIFI通信制式、4G通信制式(例如TD-LTE制式、TD-LTE和FDD-LTE混合制式)、5G通信制式。
在一些实施例中，振荡频率控制系统3还包括：第二存储模块38；第二存储模块38存储有第二对应关系数据。

第二对应关系数据可通过上述表2所示对应关系表来展示。第二对应关系数据记载有不同通信制式及其对应的频率调整方案，频率调整方案中记载有各振荡器所对应的振荡工作频率。确定模块32具体配置为根 据第二对应关系数据确定出通信模块2当前工作的通信制式所对应的频率调整方案。
需要说明的是，可根据通信模块2的实际所支持的通信制式来设计第二对应关系数据中所需记载的通信制式；然后通过预先实验/模拟的方式来获得各不同通信制式所对应的频率调整方案，仅需保持振荡器采用所确定的频率调整方案进行工作时所产生的谐波的频率位于该所确定的频率调整方案所对应通信制式的通信工作频段之外即可。
在一些实施例中，通信模块2可以根据实际需要在多个不同通信制式之间进行切换(例如，通信模块2支持4G通信和5G通信，通信模块2可在4G通信制式和5G通信制式之间作切换，相应地通信工作频段也发生切换)。此时，振荡频率控制系统3还包括：制式检测模块37，制式检测模块37配置为检测通信模块2的通信制式是否发生变化，并在检测出通信模块2的通信通信制式发生变化时控制获取模块31获取通信模块2当前工作的通信制式，再通过确定模块32和控制模块33使得显示驱动模块1内的振荡器的振荡工作频率发生相应切换，以保证振荡器工作时所产生谐波的频率始终位于通信模块2当前工作的通信工作频段之外。
在一些实施例中，通信模块2所配置的通信制式包括2G通信制式、3G通信制式、WIFI通信制式、4G通信制式、5G通信制式中的至少一种。
在一些实施例中，显示驱动模块1内所设置的振荡器包括第一振荡器和第二振荡器，第一振荡器的振荡工作频率记为OSC1，第二振荡器的振荡工作频率记为OSC2。作为一个示例，通信制式在第一通信制式(制式1)时，调用第二对应关系数据记载频率调整方案1’，第一振荡器OSC1为151MHZ，第二振荡器OSC2为165.4MHZ；通信制式在第二通信制式(制式2)时，调用第二对应关系数据记载频率调整方案2’，第一振荡器OSC1为151MHZ，第二振荡器OSC2为170.5MHZ；通信制式在第三通 信制式(制式3)时，调用第二对应关系数据记载频率调整方案3’，第一振荡器OSC1为148MHZ，第二振荡器OSC2为165.4MHZ；通信制式在第四通信制式(制式4)时，调用第二对应关系数据记载频率调整方案4’，第一振荡器OSC1为148MHZ，第二振荡器OSC2为170.5MHZ。
在一些实施例中，通信制式在第一通信制式(例如：制式1＝4G)时，调用第二对应关系数据记载频率调整方案1’，第一振荡器OSC1为151MHZ，第二振荡器OSC2为165.4MHZ；通信制式在第二通信制式(例如：制式2＝5G)时，调用第二对应关系数据记载频率调整方案2’，第一振荡器OSC1为148MHZ，第二振荡器OSC2为170.5MHZ。
图5B为本公开实施例中振荡频率控制系统的又一种结构框图。如图5B所示，在一些实施例中，振荡频率控制系统不但包括上述制式检测模块37和第二存储模块38，还包括：干扰检测模块39。
其中，制式检测模块37配置为检测通信模块2的通信制式是否发生变化；干扰检测模块39配置为在制式检测模块37检测出通信模块2的通信制式发生变化时，进一步检测通信模块2当前工作的通信工作频段(通信制式发生变化后的通信工作频段)是否存在振荡器的谐波干扰，并在检测出通信模块2当前工作的通信工作频段不存在振荡器的谐波干扰时，将通信模块2当前工作的通信制式与各振荡器当前工作的振荡工作频率建立对应关系并存储至第二存储模块38，以及在检测出通信模块2变化后的通信工作频段存在振荡器的谐波干扰时，控制获取模块31获取通信模块2当前工作的通信制式。通过上述设计，可以不断的对第二存储模块38中所存储的数据进行丰富，以提高控制精准度。
图6为本公开实施例中显示驱动模块1的一种结构框图。如图6所示，在一些实施例中，显示驱动模块1还包括：驱动单元和移动产业处理器接口(Mobile Industry Processor Interface，简称MIPI)单元(也称为MIPI接口单元)；至少一个振荡器包括：第一振荡器和第二振 荡器；第一振荡器用于为驱动单元提供时钟信号，第二振荡器用于为MIPI接口单元提供时钟信号。
其中，驱动单元一般包括栅极驱动电路(例如，用于输出Gate信号的栅极驱动电路、用于输出EM信号的栅极驱动电路、用于输出Resst信号的栅极驱动)和源极驱动电路。
可选地，第一振荡器的振荡工作频率小于或等于151.7Mhz；第二振荡器的振荡工作频率大于或等于151.7Mhz。进一步可选地，第二振荡器的振荡工作频率范围为151.7Mhz～192Mhz。
第一振荡器所设置的振荡工作频率与第二振荡器所设置的振荡工作频率，二者可以相同，也可以不同。
当然，本公开实施例中第一振荡器的数量也可以为2个或多个，例如针对每一个栅极驱动电路均配置有独立的一个第一振荡器，针对源极驱动电路也配置有独立的一个第一振荡器。
在一些实施例实施例中，显示驱动模块1还包括：寄存器，振荡器配置为根据寄存器中所记载的对应控制指令进行工作；控制模块33包括：写入单元；其中，写入单元配置为根据确定模块32所确定的各振荡器所对应的振荡工作频率向寄存器中写入相应控制指令，以供各振荡器根据寄存器中所记载的控制指令采用对应的振荡工作频率进行工作。
图7A为写入单元向寄存器内写入用于控制第一振荡器工作于151.7Mhz、控制第二振荡器工作于165.4MHz的控制指令的一种代码示意图。图7B为写入单元向寄存器内写入用于控制第一振荡器工作于151.7Mhz、控制第二振荡器工作于170.5MHz的控制指令的一种代码示意图。图7C为写入单元向寄存器内写入用于控制第一振荡器工作于148Mhz、控制第二振荡器工作于165.4MHz的控制指令的一种代码示意图。图7D为写入单元向寄存器内写入用于控制第一振荡器工作于148Mhz、控制第二振荡器工作于170.5MHz的控制指令的一种代码示意 图。如图7A至图7D所示，写入单元可通过MIPI接口向显示驱动模块内的寄存器写入相应的控制指令；其中，OSC1表示第一振荡器所配置的振荡工作频率，OSC2表示第一振荡器所配置的振荡工作频率；OxF0为第一振荡器的标识，0xC3为第二振荡器的标识。
需要说明的是，图6中仅示意性画出了显示驱动模块内设置有两个振荡器的情况，该情况仅起到示例性作用，其不会对本公开的技术方案产生限制。
在实际应用中发现，虽然可通过显示驱动模块内的寄存器来对各振荡器的振荡工作频率进行设定，但是由于显示驱动模块内的振荡器一般为RC型振荡器，受到切割(trimming)工艺精度以及环境温度的影响，振荡器的实际振荡工作频率与所设定的振荡工作频率存在偏差，从而导致振荡器工作时所谐波出现的位置与预计位置不同，继而会存在谐波对通信模块当前工作的通信工作频段产生共振干扰的风险。
再次参见图3、图4、图5所示，为有效改善上述技术问题，在一些实施例中，振荡频率控制系统还包括：频率校准模块34，频率校准模块34配置为对振荡器进行频率校准，以改善振荡器的实际振荡工作频率与所设定的振荡工作频率存在偏差的问题。
在实际应用中，可采用如下两种方式来对振荡器进行频率校准：其一、由于应用处理器(Application Processor，简称AP)中MIPI接口所配置的振荡器为石英振荡器，石英振荡器的精准度高且不受稳定变化影响，故可以利用应用处理器内的MIPI时钟的频率来对显示驱动模块内振动器的OSC频率进行校正；其二、可通过连续调整显示驱动模块内振动器的PARAM参数的方式来实现度振动器的OSC频率自动校正。
需要说明的是，本公开实施例中将频率校准模块34集成于振荡频率控制系统内，可以有效提升产品的集成度；在本公开实施例中，频率校准模块34也可以独立于振荡频率控制系统之外而存在。
