Description

一种显示屏系统及其信号传输方法 技术领域
本申请涉及显示屏技术领域，特别涉及一种显示屏系统及其信号传输方法。
 背景技术
显示屏体一般是由显示屏单元进行拆装拼接而成，常见的是通过箱体拼接。现有通过箱体拼接而成的显示屏，由于不同位置的箱体，其内部走线不同，箱体与箱体之间仅能传递图像信息、控制信息，而无法传递位置信息。导致在箱体装配过程中，需要花费较长来确定箱体的安装位置，再进行装配调试。而只有明确了箱体的具体坐标，就能够实现屏体的信号调试、装置调试。
箱体间信号传输主要指的是由箱体拼接而成的显示屏中，箱体与箱体之间的信号传输。这里所指的信号有许多种，包括显示屏播放的视屏信号、箱体的位置信号和箱体工作的状态信息等。通常情况下来讲，这些信号都是借助特定的信道进行传输的。
现有的LED箱体之间的通信是通过网线进行的，这种信号传输方式存在以下不足：（1）需要在箱体边框部分进行有线连接，穿接线不方便。
（2）网线传输存在接触不良情况，且对箱体的密封和防水要求较高。
（3）多数箱体设计考虑到加工工艺、维护成本等，甚至会放弃此项功能，不在箱体间横向进行通信传输。
（4）网线连接导致不同位置的箱体会出现不同的走线方式，而在一次拆装中箱体安放位置不对，则需要对内部线路进行重新插拔连接和程序调试，十分不便。
所以，对于需要进行拆装的显示屏体，提出一种新的显示屏单元之间的信号传输技术就显得十分有必要。
 技术问题
本发明实施例提供一种显示屏系统及其信号传输方法，以解决显示屏单元之间通过网线进行信号传输而导致结构复杂，且安装调试不方便的技术问题。
 技术解决方案
根据本发明实施例的一个方面，提供的一种显示屏系统，所述显示屏系统包括显示屏阵列，所述显示屏阵列包括若干拼接在一起的显示屏单元，每一显示屏单元包括边框和固定在所述边框的换能器装置，相邻的所述显示屏单元的所述换能器装置接触，通过所述换能器装置使相邻的所述显示屏单元之间进行信号传输。
根据本发明实施例的另一个方面，提供的一种显示屏系统的信号传输方法包括：S1、将每个所述显示屏单元的边框拼接在一起，并使相邻的所述显示屏单元的所述换能器装置接触。
S2、相邻的所述显示屏单元之间通过所述换能器装置进行信号传输。
 有益效果
本发明实施例，通过将换能器装置直接集成的显示屏单元边框上，换能器装置产生的机械震动被直接释放在显示屏单元的边框上，从而能够正常进行信号传输。并且，由于信号只在显示屏单元间进行横向或纵向信号传输，显示屏单元能够通过换能器装置知晓其左右或上下的显示屏单元的位置，所以借助相邻显示屏单元的连接结构进行信号传输的精度和准确度较高，抗干扰能力强。此外，由于显示屏单元之间无需网线连接，拆装调试十分方便。

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
 本发明的实施方式
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚、明白，以下结合附图和实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅以解释本发明，并不用于限定本发明。
在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本发明的说明，其本身没有特定的意义。因此，“模块”、“部件”或“单元”可以混合地使用。
在一个实施例中，如图1至图17所示，本发明提供一种显示屏系统，所述显示屏系统包括显示屏阵列，所述显示屏阵列包括若干拼接在一起的显示屏单元100，每一显示屏单元100包括边框20和固定在所述边框20的换能器装置10，将每个所述显示屏单元100的边框20拼接在一起，使相邻的所述显示屏单元100的所述换能器装置10接触，相邻的所述显示屏单元100之间通过所述换能器装置10进行信号传输，实现每一所述显示屏单元100之间信号传输。
在一个实施例中，如图1、图12和图15所示，所述显示屏系统还包括锁紧装置200，所述锁紧装置200用于锁紧相邻显示屏单元100，使相邻显示屏单元100能够接触。所述锁紧装置200在锁紧相邻显示屏单元100的同时，也同时锁紧了相邻显示屏单元100的换能器装置10，使相邻的两换能器装置10更接触。优选地，所述锁紧装置200为锁紧螺丝组件。
在本实施例中，将作为机械波发生装置的换能器装置被集成在显示屏单元的边框上，换能器装置与显示屏单元边框是接触的，使得相邻两显示屏单元之间的缝隙很小而接触，同时，两相邻显示屏单元用锁紧装置进行锁紧，使两相邻显示屏单元之间更加接触，使得机械波能够以较高的频率进行传递。如果两显示屏单元（比如箱体）之间无法紧密相连，则容易导致机械波在传递过程中出现损失和干扰，甚至会中断，但是机械波信号可以通过其他的硬连接媒介，如两相邻显示屏单元间的锁紧装置来进行传播。机械波的传播精准与否，并不在于两信号源的距离长短，而是在于结构件是否连接紧密，使机械波传递过程中震动频率和振幅不会出现较大的削弱。由于两相邻显示屏单元能够接触，整个传输过程中仅是两换能器（或振子）之间的接触，而其它结构上并没有产生接触，显示屏单元的边框对信号传输没有造成影响，所以借助两相邻显示屏单元的连接结构进行信号传输，信号传输的精度和准确度较高，传输效率高、成本低、容错率高、要求低、抗干扰能力强，适用于较为复杂的信息信号的传输。且由于显示屏单元之间的拼装无需网线连接，拆装十分方便。
在一个实施例中，所述显示屏单元100包括：边框20和换能器装置10，所述换能器装置10固定在所述边框20，所述显示屏单元100通过所述换能器装置10进行信号传输。

具体地，如图2所示，所述换能器装置10包括：换能器11、控制器12、引出电缆13；其中：所述引出电缆13，用于为所述换能器装置10传输信号及供电；具体地，所述引出电缆13用于传输信号给所述控制器12，以及为所述控制器12供电。
所述控制器12，用于处理所述引出电缆13传输的信号，并将处理后的所述信号传输给所述换能器11。
优选地，所述控制器12为控制驱动装置，其内包括调制/解调电路、放大电路、阻抗匹配电路、带通滤波电路，其中：所述调制/解调电路，用于将所述信号进行调制/解调，得到调制/解调信号。
所述放大电路，用于将所述调制/解调信号进行信号功率放大，得到放大后的信号。

所述换能器11，用于将所述控制器12传输的处理后的所述信号换能，转换为机械波。
所述换能器11是由机械震动系统和电储能元件组成，具有收发两用的功能。所述机械震动系统的机械震动和所述电储能元件的电能可以相互转换。即当所述换能器用作发射换能器时，所述电储能元件的电场或磁场的变化通过电磁场效应推动换能器的机械震动系统进入震动状态，使所述电储能元件的电能转换成机械震动。当所述换能器用作接收换能器时，所述机械震动系统的震动变化推动所述电储能元件的电场或磁场的变化，使所述机械震动系统的机械震动转换成电能。
可选地，所述换能器11包括以下之一：压电换能器、静电换能器、磁致伸缩换能器、超声波换能器。
在本实施例中，所述换能器11以收发两用超声波换能器为例对所述换能器的结构进行说明。所述超声波换能器为收发两用超声波换能器，其结构包括外壳、声窗、压电陶瓷圆盘换能器、背衬、引出电缆、Cymbal阵列接收器组成，其中，所述Cymbal阵列接收器由引出电缆、8~16只Cymbal换能器、金属圆环、橡胶垫圈组成。所述Cymbal阵列接收器位于压电陶瓷圆盘换能器之上；压电陶瓷圆盘换能器用于发射和接收超声波信号；Cymbal阵列接收器用于接收压电陶瓷圆盘换能器频带之外的多普勒回波信号。

在一个实施例中，如图3所示，所述换能器装置10还可以包括连接层15，所述连接层15是振子14在端部连接处形成的特殊处理结构，用于使相邻两振子之间连接更紧密。
优选地，所述显示屏单元100为矩形显示箱体或矩形显示模组。
在一个实施例中，如图1、图4、图5、图10、图12和图13所示，在所述显示屏单元100的两相对边框20各设置一个换能器装置10，可以实现双路信号传输。
图1和图12所示为两显示屏单元拼接在一起的结构示意图。在该实施例中，通过锁紧装置200将相邻显示屏单元100锁紧，使相邻的两个显示屏单元100的两边框20接触在一起，使得固定在各自边框20的换能器装置10接触在一起，实现双路信号传输。
图10和图13所示为多个显示屏单元拼接在一起形成显示屏阵列的结构示意图。在该实施例中，通过锁紧装置200将相邻显示屏单元100锁紧，使相邻的两个显示屏单元100的两边框20接触在一起，使得固定在各自边框20的换能器装置10接触在一起，实现双路信号传输。
在实施例中，通过在所述显示屏单元的两相对边框各设置一个换能器装置，可以实现双路信号传输，双路信号传输只在显示屏单元间进行横向信号传输或者纵向信号传输，显示屏单元能够通过换能器装置知晓其左右或上下的显示屏单元的位置，在相邻显示屏单元之间进行信号传输时，无需进行有线连接，只需要保证相邻显示屏单元能够接触，使相邻显示屏单元的换能器接触，整个传输过程中仅是两换能器（或振子）之间的接触，而其它结构上并没有产生接触，显示屏单元的边框对信号传输没有造成影响。
在一个实施例中，如图1、图6、图7、图11、图12和图14所示，在所述显示屏单元100的每个边框20各设置一个换能器装置10，可以实现四路信号传输。
图1和图12所示为两显示屏单元拼接在一起的结构示意图。在该实施例中，通过锁紧装置200将相邻显示屏单元100锁紧，使相邻的两个显示屏单元100的两边框20接触在一起，使得固定在各自边框20的换能器装置10接触在一起，实现四路信号传输。
图12和图14所示为多个显示屏单元拼接在一起形成显示屏阵列的结构示意图。在该实施例中，通过锁紧装置200将相邻显示屏单元100锁紧，使相邻的两个显示屏单元100的两边框20接触在一起，使得固定在各自边框20的换能器装置10接触在一起，实现四路信号传输。
在实施例中，通过在所述显示屏单元的每个边框各设置一个换能器装置，可以实现四路信号传输，既可以进行显示屏单元间的横向信号传输，又可以进行纵向信号传输，显示屏单元能够通过换能器装置知晓其左右及上下的显示屏单元的位置，从而可以实现显示屏单元间的信号传输的高容错率，即使任意相邻两显示屏单元的信号传输出现中断无法连接，也可以通过纵向传输来规划新的路径以知晓传输信息。
在一个实施例中，如图8、图15、图16所示，在所述显示屏单元100的一边框20设置一个换能器装置10，另一相对边框20设置一个译码装置30，可以实现单向横向信号传输。其中，所述译码装置30用于翻译（译码）相邻显示屏单元的机械波，包括译码电路及与其连接的引出电缆。
图15和图16所示为多个显示屏单元拼接在一起形成显示屏阵列的结构示意图。在该实施例中，通过锁紧装置200将相邻显示屏单元100锁紧，使相邻的两个显示屏单元100的两边框20接触在一起，使得固定在各自边框20的换能器装置10和译码装置30接触在一起，实现横向单向信号传输。
在实施例中，通过在所述显示屏单元的一边框设置一个换能器装置，另一相对边框设置一个译码装置，在相邻显示屏单元中，对于本显示屏单元来说只能单向传输信号，即仅能接收相邻的上一个显示屏单元的传输信号，发送信号给相邻的下一个显示屏单元，但无法发送信号给相邻的上一个显示屏单元，从而实现横向的单向横向信号传输，结构简单。
在一个实施例中，如图9、图15、图17所示，在所述显示屏单元100的两相邻边框20各设置一个换能器装置10，另两相邻边框20各设置一个译码装置30，可以实现单向横向信号传输和纵向信号传输。其中，所述译码装置30用于翻译（译码）相邻显示屏单元的机械波，包括译码电路及与其连接的引出电缆。
图15和图17所示为多个显示屏单元拼接在一起形成显示屏阵列的结构示意图。在该实施例中，通过锁紧装置200将相邻显示屏单元100锁紧，使相邻的两个显示屏单元100的两边框20接触在一起，使得固定在各自边框20的换能器装置10和译码装置30接触在一起，实现单向横向信号传输和纵向信号传输。
在实施例中，通过在所述显示屏单元的两相邻边框各设置一个换能器装置，另两相邻边框各设置一个译码装置，在相邻显示屏单元中，对于本显示屏单元来说只能单向传输信号，即仅能接收相邻的上一个显示屏单元的传输信号，发送信号给相邻的下一个显示屏单元，但无法发送信号给相邻的上一个显示屏单元，从而实现单向横向信号传输和纵向信号传输，结构简单。
在以上的本实施例中，基于包括本发明提供的所述换能器装置的显示屏单元，可以实现显示屏单元间的信号传输，从而可以知晓显示屏单元屏间的位置信息。
如果有一台无线信号发送基站，藏在由若干拼接在一起的显示屏单元组成的显示屏系统屏体后方，对该显示屏系统屏体发送视频信号。无线信号发送基站对每一个显示屏单元都发送完整的视频信息，显示屏单元再根据自身位置，以截取视频信息特定范围，即显示屏单元对应的显示范围的视频信息，并对此进行播放。这样一来，每个显示屏单元都有一份完整的视频信息，但是每个显示屏单元都仅播放所属位置的视频信息。此时显示屏单元就需要知道自身相对于屏体的坐标，知道自身位置信息才能准确的划分出播放的范围。
基于包括本发明提供的所述换能器装置的显示屏单元，可以实现显示屏单元间的信号传输，从而可以知晓显示屏单元屏间的位置信息。显示屏单元能够知道自身的位置信息，并且还能够知道自身周围的显示屏单元情况（包括位置信息及播放的视频信息内容）才能准确的播放视频信息内容。
对每个显示屏单元都传递完整的视频信息，可能需要传输的信息量有点大，但是统一收发同一内容的形式，足够简单，故对视频信息不用作过多的处理，也能把信号收发站集成为一个，信号传输主路径化简为一条。
如图18所示，基于前述各实施例的显示屏系统，本发明实施例提供一种显示屏系统的信号传输方法，所述方法包括：S1、将每个显示屏单元的边框拼接在一起，并使相邻的所述显示屏单元的换能器装置相接触。

上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，这些均属于本发明的保护之内。
 工业实用性
本发明实施例提供的一种显示屏系统及其信号传输方法，通过将换能器装置集成在显示屏单元的边框上，所述换能器装置产生机械波，利用不同频率的机械震动直接释放在显示屏单元的边框上，使显示屏单元能够实现信号传输。而且，由于信号只在显示屏单元间进行横向或纵向信号传输，显示屏单元能够通过换能器装置知晓其左右或上下的显示屏单元的位置，在相邻显示屏单元之间进行信号传输时，无需进行有线连接，只需要保证相邻显示屏单元能够接触，使相邻显示屏单元的换能器接触，整个传输过程中仅是两换能器（或振子）之间的接触，而其它结构上并没有产生接触，显示屏单元的边框对信号传输没有造成影响，所以借助相邻显示屏单元的连接结构进行信号传输，信号传输的精度和准确度较高，抗干扰能力强。此外，由于显示屏单元之间无需网线连接，拆装调试十分方便。因此，具有工业实用性。
