背景技术
LED显示屏的优势除了亮度高、色域广优势以外,可以灵活拼接为大型显示屏的优势至关重要。LED显示屏是由一个一个的配置有接收卡的显示箱体拼接组成,显示箱体配置的接收卡之间通过网线连接,用以传递图像数据信号。LED显示屏行业发展已有多年之久,但就目前市场而言,产品普遍还停留在1Gbps的传输速率期间;随着LED显示屏向小间距显示屏方向发展,1Gbps的传输速率显然不够。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
参见图1、图2和图3,本申请实施例提供的一种接收卡10,包括:电路板11和设置在电路板11上的接插组件12、可编程逻辑器件13、存储器件14、物理层收发器组15a及15b、和多个例如两个以太网接口16a及16b。
其中,接插组件12电连接可编程逻辑器件13,其例如是由两个具有相同引脚数的接插件12a、12b构成,此处的接插件12a、12b例如分别是120Pin高密接插件,但本申请实施例并不以此为限。再者,从图2可知,接插组件12位于电路板11的一侧(例如电路板11的底面侧),且可编程逻辑器件13、存储器件14、物理层收发器组15a及15b、和以太网接口 16a及16b位于电路板11的另一侧(例如电路板11的顶面侧);这种排布方式便于接收卡11与转接板(图未示)的插接固定。此外,从图3可知,接插组件12包含显示数据单端信号引脚组121、显示控制信号单端信号引脚组123和显示数据差分信号引脚组125,可编程逻辑器件13电连接显示数据单端信号引脚组121和显示数据差分信号引脚组125,以用于以单端信号和LVDS(Low Voltage Differential Signaling,低电压差分信号)差分信号二选一方式输出显示数据比如RGB数据;以及可编程逻辑器件13电连接显示控制信号单端信号引脚组,以用于以单端信号输出显示控制信号比如行译码信号、使能信号、锁存信号、时钟信号甚至行消隐信号。如此一来,接收卡11在供给LED模组显示数据时不仅可以使用RGB数据单端信号传输,也可以直接以LVDS差分信号传输。LVDS差分信号与传统的单端信号相比,其优点有:(1)抗干扰能力强,干扰噪声一般会等值、同时的被加载到两根信号线上,而其差值为0,即噪声对信号的逻辑意义不产生影响;(2)能有效抑制电磁干扰(EMI),由于两根线靠得很近且信号幅值相等,这两根线与地线之间的耦合电磁场的幅值也相等,同时它们的信号极性相反,其电磁场将相互抵消,故对外界的电磁干扰也小。
可编程逻辑器件13例如采用FPGA(Field Programmable Gate Array,现场可编程门阵列)器件。
存储器件14电连接可编程逻辑器件13,其例如是DDR4、DDR3、DDR2、LPDDR2、SDRAM等,同时可以根据实际需求来判断使用存储器件的数量。
以太网接口16a及16b分别通过物理层收发器15a及15b电连接可编程逻辑器件13配置的两个SerDes通道。本实施例中,每个SerDes通道包括两对差分信号线,以及所述两对差分信号线中的一对差分信号线用于数据发送且另一对差分信号线用于数据接收。物理层收发器15a及15b例如是10Gbase-T或5Gbase-T型以太网物理层收发器,其可以采用市售的AQR111C、AQR114C、BCM54892、BCM54992、BCM54991等芯片。本实施例搭配SerDes 通道,使得单个以太网接口16a/16b的传输速率可以为10Gbps/5Gbps/2.5Gbps/1Gbps。再者,以太网接口16a、16b可以分别是集成网变的RJ45,或者是采用网变与RJ45分离式设计,又或者是2*1集成网变的RJ45。
考虑到图1所示实施例依旧是用插拔网线的方式来传输信号,由于网线频繁拔插相对易损坏,因此图4所示实施例在图1所示实施例的基础上,增加了多个例如两个USB3.0接口,用来扩展信号传输方式。
具体地,如图4所示,本实施例的接收卡30包括:电路板31和设置在电路板31上的接插组件32、可编程逻辑器件33、存储器件34、物理层收发器组35a及35b、多个例如两个以太网接口36a及36b、多个例如两个USB3.0接口37a及37b、和直流电源电路38。其中,接插组件32、可编程逻辑器件33、存储器件34、物理层收发器组35a及35b和以太网接口36a及36b的结构及功能与图1所示的接插组件12、可编程逻辑器件13、存储器件14、物理层收发器组15a及15b和以太网接口16a及16b的结构及功能类似,故在此不再赘述。
再者,USB3.0接口37a、37b分别电连接可编程逻辑器件33配置的多个SerDes通道,并且USB3.0接口37a、37b还电连接直流电源电路38以用于获取电源信号向外传送。此处的USB3.0接口37a、37b为具有多对高速差分信号引脚和电源信号引脚的接口,因此其还可以替换成其他具有多对高速差分信号引脚和电源信号引脚的接口,比如Mini HDMI接口。
承上述,针对接收卡30的两个USB3.0接口(例如Micro USB3.0接口或其他类型USB3.0接口),衍生出图5所示采用无线传输子卡40的显示控制卡组件。图5所示无线传输解决方案的主要目的是解决行业网线频繁拔插易坏、不稳定,前期安装和后期维护成本较大的痛点问题。同时随着LED显示屏行业的发展,小间距LED显示屏的需求越来越多,前维护的设计越来越流行;针对LED显示屏前维护方案,无线传输无疑提供了一个非常优质的方案,方便LED显示屏设计和现场安装维护。
具体地,如图5所示,每个USB3.0接口37a、37b通过USB3.0线连接一个无线传输子卡40。此处的USB3.0线为一种能够同时传输数据信号和电源信号的线缆。再者,如图6所示,无线传输子卡40包括:电路板和设置在所述电路板上的直流转直流电路43、无线发送芯片45a和无线接收芯片45b。所述电路板上设有焊盘组41,且焊盘组41电连接USB3.0线的一端。直流转直流电路43电连接焊盘组41、无线发送芯片45a和无线接收芯片45b,以用于从焊盘组41获取电源信号并向无线发送芯片45a和无线接收芯片45b提供工作电压。无线发送芯片45a和无线接收芯片45b间隔设置并通过SerDes通道电连接焊盘组41;所述SerDes通道包含两对差分信号线,以及所述两对差分信号线中的一对差分信号线用于数据发送、且另一对差分信号线用于数据接收。再者,无线发送芯片45a和无线接收芯片45b的工作频率位于毫米波频段。此处的毫米波频段典型地是指频率范围为30GHz~300GHz,相应波长为1毫米~10毫米。本实施例这种工作在毫米波频段的无线发送芯片45a、无线接收芯片45b非常适合于LED显示屏中显示箱体的应用场合,因为LED显示屏典型地由多个显示箱体拼接而成,当将无线传输子卡40装设在各个显示箱体之后,首要考虑的问题是如何避免同一个LED显示屏中不需要进行数据收发的两个无线传输子卡40之间的无线信号串扰,而本实施例无线传输子卡40中的无线发送芯片45a、无线接收芯片45b工作在毫米波频段,相较于现有技术中的WiFi模块、蓝牙模块等无线传输模块而言可以大大降低无线信号串扰可能。再者,基于目前无线芯片的性能和频段的易获得性,本实施例优选为无线发送芯片45a、无线接收芯片45b的工作频率为频率范围57GHZ-67GHZ或71GHZ-87GHZ,例如为60GHZ或80GHZ。
参见图7,本实施例的接收卡50去掉了图4所示接收卡30的以太网接口+物理层收发器,将可编程逻辑器件的SerDes通道全部连接至USB3.0等接口(对应第一类型接口)。此设计不仅仅可以缩小接收卡的尺寸大小,更是可以让采用该种接收卡的LED显示屏控制系统 设计方案可以变得多元化。
具体地,如图7所示,接收卡50包括:电路板51和设置在电路板51上的接插组件52、可编程逻辑器件53、存储器件54、多个例如四个USB3.0接口57a及57b和59a及59b、以及直流电源电路58。其中,接插组件52、可编程逻辑器件53和存储器件54结构及功能与图1所示的接插组件12、可编程逻辑器件13和存储器件14的结构及功能类似,故在此不再赘述。
再者,USB3.0接口57a、57b、59a、59b分别电连接可编程逻辑器件53配置的多个SerDes通道,并且USB3.0接口57a、57b、59a、59b还电连接直流电源电路58以用于获取电源信号向外传送。此处的USB3.0接口57a、57b、59a、59b为具有多对高速差分信号引脚和电源信号引脚的接口,因此其还可以替换成其他具有多对高速差分信号引脚和电源信号引脚的接口,比如Mini HDMI接口。
另外,对于图7中设有四个USB3.0接口57a、57b、59a、59b的接收卡50,可以直接在子卡上进行传输速率和信号传输方式的确定,因为对于每个USB3.0接口而言,都可以有多种连接方案,可以用来接无线传输子卡,也可用来接有线网络传输子卡,以下结合图8至图11列举出接收卡50的四个USB3.0接口57a、57b、59a、59b的多种连接方案。
具体地,如图8所示,可以将四个USB3.0接口57a、57b、59a、59b分别通过USB3.0线与无线传输子卡40连接,实现无线信号传输。
或者,如图9所示,可以将四个USB3.0接口57a、57b、59a、59b分别通过USB3.0线与有线网络传输子卡60连接。至于有线网络传输子卡60,如图10所示,其包括:电路板和设置在所述电路板上的USB3.0接口(对应第二类型接口)61、直流转直流电路63、物理层收发器65和以太网接口67。USB3.0接口61连接USB3.0线的一端,其为一种具有多对高速差分信号引脚和电源信号引脚的接口。直流转直流电路63电连接USB3.0接口61和物理 层收发器65,以用于从USB3.0接口61获取电源信号并向物理层收发器65提供工作电压。物理层收发器65通过SerDes通道电连接USB3.0接口61,且此处的SerDes通道包含两对差分信号线,以及所述两对差分信号线中的一对差分信号线用于数据发送且另一对差分信号线用于数据接收。再者,此处的物理层收发器65可以选用1GBase-T/2.5GBase-T/5GBase-T/10GBase-T型以太网物理层收发器等。此外,以太网接口67电连接物理层收发器65,其例如说集成网变的RJ45,或者采用网变和RJ45分离式设计。
又或者,如图11所示,可以将四个USB3.0接口57a、57b、59a、59b分别与两个无线传输子卡40和两个有线网络传输子卡60连接。
以上仅列出采用接收卡50的三种显示控制卡组件的结构,但本申请实施例并不以此为限;因为接收卡50的灵活性,可以用于多种场景,因此可以随着场景的不同去更改子卡的方案设计。
综上所述,本申请实施例的接收卡和显示控制卡组件可以具有以下一个或多个有益效果:(i)对于传输速率解决方案,能够有效解决千兆带宽不够问题,更适用于小间距应用,带宽可以选择10G/5G/2.5G/1G甚至其他带宽,且灵活性更高、适用性更强;(ii)对于信号传输方式解决方案,解决了传统传输方式网线频繁拔插易坏这一痛点问题,可以根据应用场景的不同去选择不同的信号传输方式,大大提升了LED显示屏控制系统的多元化与实际有效应用性,极大的缩短了安装和维护的工作量;以及(iii)保留常规的RGB单端信号外增加了LVDS差分信号,可以加强传输抗干扰能力,能有效抑制电磁干扰(EMI)、提升EMC。
此外,可以理解的是,前述各个实施例仅为本申请的示例性说明,在技术特征不冲突、结构不矛盾、不违背本申请的发明目的前提下,各个实施例的技术方案可以任意组合、搭配使用。
最后应说明的是:以上实施例仅用以说明本申请的技术方案,而非对其限制;尽管 参照前述实施例对本申请进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
