Description

显示控制系统和显示屏控制器 技术领域
本申请涉及显示技术领域，尤其涉及一种显示控制系统以及一种显示屏控制器。
背景技术
目前，显示屏例如LED显示屏一般都是由多个LED箱体拼接而成，每个LED箱体都安装有接收卡，上电启动时接收卡能使LED箱体显示图像内容。
一方面，LED显示屏与其前端的显示控制系统之间通常采用网线连接，而网线的有效传输距离一般在100米以内，因此随着LED显示屏的尺寸越来越大，将带载LED显示屏全部显示区域的所有网线均连接至单一设备的方案已越来越难以满足LED显示屏与前端的显示控制系统之间的网线连接需求，其导致显示控制系统的放置位置受限，使得连线灵活性差。
再一方面，显示控制系统如何方便快捷地获取其与LED显示屏之间的连接状态，实现远程监控变得越来越重要。
另一方面，LED显示屏需要搭配前端的显示控制系统才能进行图像正常显示，然而现有的显示控制系统所采用的各种设备功能比较单一，其导致在现场搭建LED显示系统时需要携带多种不同功能的设备，而该种需携带多种不同功能的设备之需求会造成用户现场搭建系统的不便利。

【第一实施例】
请参见图1，其为本申请第一实施例提供的一种显示控制系统的结构示意图。如图1所示，显示控制系统10用于带载包含显示区域21和显示区域22的显示屏20且包括：显示屏控制器11、信号转换器13和信号转换器15。
其中，信号转换器13连接显示屏控制器11、且用于连接显示屏20以带载显示区域21。信号转换器15连接显示屏控制器11、且用于连接显示屏20以带载显示区域22。信号转换器13、15连接显示屏控制器11的接口为第一类型接口，信号转换器13、15用于连接显示屏20的接口为不同于第一类型接口的第二类型接口。信号转换器13、15分设在显示屏20的不同侧，例如图1所示的显示屏20的左右两侧、或者显示屏20下方的左右两侧(也即图1中显示屏20的中间虚线的两侧)。本实施例中，将显示屏20划分成多个显示区域例如21、22并由多个信号转换器例如13、15来分别带载，这样一来，信号转换器13、15与显示屏20之间的连线(典型的为网线)灵活度较高，而且也可以减少线材的长度。
为便于理解本实施例的显示控制系统10，下面结合图2和图3对本实施例的显示控制系统10进行详细描述。
图2为显示屏控制器11的一种具体结构示意图。如图2所示，显示屏控制器11包括：主控电路111(或称主处理电路)、视频接口113、视频解码电路115、 驱动电路117a、光纤接口119a、驱动电路117b和网口119b。
视频接口113用于连接外部视频源以接收视频信号输入。本实施例中，视频接口113的数量可以是一个、也可以是多个，而且视频接口113例如是数字视频接口、模拟视频接口或其组合。举例来说，视频接口113例如包括HDMI接口(High Definition Multimedia Interface，高清晰度多媒体接口)、DP(DisplayPort)接口和双链路DVI接口(Digital Visual Interface，数字视频接口)。
视频解码电路115连接在视频接口113和主控电路111之间，其通常设置有视频解码芯片，而所设置的视频解码芯片与视频接口113的类型相关。例如当视频接口113为DVI接口，则视频解码芯片采用DVI视频解码芯片；当视频接口113为DP接口，则视频解码芯片采用DP视频解码芯片；当视频接口113为HDMI接口，则视频解码芯片采用HDMI视频解码芯片。
主控电路111例如包括可编程逻辑器件1111和连接可编程逻辑器件1111的微控制器1113例如MCU(Micro Controller Unit，微控制单元)。可编程逻辑器件1111例如是FPGA(Field Programmable Gate Array，现场可编程门阵列)，微控制器1113例如用于加载及配置FPGA以及作为显示屏控制器11与外部设备进行通信的控制器，例如微控制器1113可以通过百兆网口、串口、USB口等与外部设备交互，也可以连接人机交互装置例如按键、LCD(Liquid Crystal Display，液晶显示)屏等。典型地，视频解码电路115从视频接口113获取输入的视频信号后，将解码得到的数据和控制信号传给主控电路111的可编程逻辑器件1111，可编程逻辑器件1111通过内部或外接RAM进行缓存、并进行更换时钟域和位宽变换操作，然后将处理后的数据输出。举例来说，可编程逻辑器件1111的内部逻辑可以包括数据输入模块、双口RAM及其控制模块、24bit转8bit模块、数据输出模块；数据输入模块将输入的视频信号(包括数据、时钟、使能、行场同步信号)分配给后端的双口RAM及其控制模块，并控制着整个系统的同步，双口RAM的控制模块控制RAM的读写操作，尤其是对开始写、写停、开始读、读停这四个状态的控制，从双口RAM输出的数据经过并串转换后传输给数据输出模块，数据输出模块则按照一定的格式将接收到的数据进行打包输出。

驱动电路117b连接在主控电路111的可编程逻辑器件1111与网口119b之间。本实施例中，驱动电路117b包括以太网物理层收发器(PHY)，而为了增强信号传输距离，还可以在以太网物理层收发器的输出侧加设网络变压器。更具体地，针对多路网口119b，驱动电路117b典型地配置有多路以太网物理层收发器和网络变压器的组合，例如当网口119b为十六路时，驱动电路117b可以配置十六路以太网物理层收发器和十六路网络变压器的组合。当然，值得一提的是，本实施例的网口119b的数量并不做限制，能满足实际应用需求即可。另外，值得说明的是，网口119b和驱动电路117b的设置，有利于显示屏控制器11的输出接口多样化，进而提升其兼容性；而且为了实现网口119b与光纤 接口119a具有相同的带载能力，光纤接口与网口的配置数量比优选为1:4。
图3为信号转换器13的一种具体结构示意图。如图3所示，信号转换器13例如为光电转换器，其包括：信号转换控制电路131、驱动电路133、光纤接口135、驱动电路137和网口139。
信号转换控制电路131例如包括可编程逻辑器件1311和连接可编程逻辑器件1311的微控制器1313例如MCU。可编程逻辑器件1311用于进行信号转换控制，其例如是FPGA。微控制器1313例如用于加载及配置FPGA以及作为信号转换器13与外部设备进行通信的控制器，例如微控制器1313可以通过百兆网口、USB口等与外部设备交互来实现对系统程序进行更新。
驱动电路133连接在光纤接口135和信号转换控制电路131中的可编程逻辑器件1311之间。本实施例中，驱动电路133包括：光模块，用于进行光电转换，例如可以将通过光纤接口135输入的光信号转换成电信号输入至可编程逻辑器件1311。举例来说，光模块可以是SFP光模块。更具体地，针对多路光纤接口135，驱动电路133典型地配置有多个光模块，例如当光纤接口135为两路时，驱动电路133可以配置两个光模块。当然，值得一提的是，本实施例的光纤接口135的数量并不做限制，能满足实际应用需求即可。
驱动电路137连接在网口139和信号转换控制电路131中的可编程逻辑器件1311之间。本实施例中，驱动电路137包括以太网物理层收发器(PHY)，而为了增强信号传输距离，还可以在以太网物理层收发器的输出侧加设网络变压器。更具体地，针对多路网口139，驱动电路137典型地配置有多路以太网物理层收发器和网络变压器的组合，例如当网口139为八路时，驱动电路137可以配置八路以太网物理层收发器和网络变压器的组合。当然，值得一提的是，本实施例的网口139的数量并不做限制，能满足实际应用需求即可。另外，值得说明的是，为了实现网口139与光纤接口135具有相同的带载能力，光纤接口与网口的配置数量比优选为1:4。
至于信号转换器15，其可以与信号转换器13具有相同的结构配置，例如均配置有信号转换控制电路、网口、光纤接口和相关驱动电路，故在此不再赘述。当然，信号转换器13和信号转换器15可以具有相同数量的光纤接口和网口，也可以具有不同数量的光纤接口和网口。
另外，为了更清楚的理解本实施例的显示控制系统10，下面以显示屏控制器11配置有四路光纤接口，信号转换器13、15分别配置有两路光纤接口和八路网口作为举例描述显示控制系统10的大致工作过程，其中显示屏控制器11通过光纤连接信号转换器13的两路光纤接口分别作为一路主控光纤接口和一路备份光纤接口，类似地显示屏控制器11通过光纤连接信号转换器15的两路光纤接口分别作为一路主控光纤接口和一路备份光纤接口，信号转换器13的八路网口中的部分或全部连接显示屏20以带载显示区域21，信号转换器15的八路网口中的部分或全部连接显示屏20以带载显示区域22；备份光纤接口的设置，有利于使系统工作更加可靠。
承上述，视频信号经由显示屏控制器11的视频接口113输入，经视频解码电路115进行视频解码后送至主控电路111的可编程逻辑器件1111进行处理以得到处理后信号，该处理后信号经由驱动电路117a转换为相应的光信号后通过光纤接口119a及光纤传送至信号转换器13、15。接下来，以信号转换器13为例，其光纤接口135接收到来自显示屏控制器11的光信号，由驱动电路133将该光信号转换成相应的电信号送至信号转换控制电路131中的可编程逻辑器件1311进行协议格式转换得到以太网数据信号(其相当于可编程逻辑器件1311 配置有信号转换单元，以将对应光信号的电信号转换成以太网数据信号)，之后以太网数据信号经由驱动电路137输出至网口139，再由连接至网口139的网线传送至显示屏20的显示区域21进行图像显示。举例来说，对于显示屏20的分辨率的一维方向最大宽度位于范围(1920,4096)内(也即大于1920且小于4096)的特定应用场合下，若采用单台信号转换器(例如带有十六路网口)，则该单台信号转换器的放置位置比较受限，而若采用本申请前述实施例的利用多台例如两台信号转换器，则与显示屏20的网线连接就会比较灵活，而且使用的网线长度也可以明显减少。
最后，值得一提的是，在其他实施例中，也可以考虑显示屏控制器11不设置备份光纤接口，因此对于连接两个信号转换器13、15而言，则显示屏控制器11可以只设置两个光纤接口119a作为主控接口，而信号转换器13、15也可以均只设置一个光纤接口135。在另一实施例中，在考虑显示屏控制器11不设置备份光纤接口的情形下，显示屏控制器11可以利用四路光纤接口119a带载四台信号转换器。
【第二实施例】
当例如在显示屏控制器和显示屏之间利用信号转换器例如光电转换器来实现信号的长距离稳定传输时，显示屏控制器与信号转换器之间的距离通常会比较远，如此一来，如何方便快捷地获取信号转换器与显示屏之间的连接状态，实现远程监控就变得尤为重要。
