Description

一种LED显示屏一体化显示系统
技术领域
本发明涉及显示技术领域,尤其涉及一种LED显示屏一体化显示系统。
背景技术
目前,现在的LED显示系统结构是将信号源采用信号线的方式传输至拼接器,将HDMI/DVI/SDI等图像格式归一化,对图像进行分割、缩放、堆叠,再通过信号线将信息传递给发送器,发送器再通过网线发送至接收卡,接收卡再传输至驱动板3,驱动每一块LED灯板工作,现有技术存在以下不足:信号源到拼接器往往距离过长,需要额外增加传输器、转换器、延长器,拼接器和发送器往往是不同厂家生产,需要解决兼容性和稳定性的问题,发送器需要部署大量的网线到大屏幕后方的接收卡,线缆具有长度限制、放线位置需要反复沟通、埋管布线需要较高的沟通成本和材料成本,系统经过两次信号转化,导致信号多次转换损耗、信号多次采集转换延时增大、封装和解封浪费大量成本,大型LED屏幕设置复杂,需要繁琐的设置接收卡的顺序、位置、像素尺寸等。
发明内容
本发明所要解决的技术问题在于:提供一种LED显示屏一体化显示系统,图像全部以流媒体形式直接到达LED显示屏,无需前端的拼接器、发送器、以及接收器,且传至LED显示屏的信号数量不再受限于拼接器输入端口的数量,系统大大简化,图像的损失大量降低,且延时大量减小。
为解决上述技术问题,本发明提出了一种LED显示屏一体化显示系统,包括LED显示屏,所述LED显示屏上设有至少一块LED灯板,所述LED灯板上设有驱动板,所述驱动板上设有无线通讯接受模块,还包括以太网络以及设置在LED显示屏上的图像拼接叠放缩放处理器,所述图像拼接叠放缩放处理器上设有无线通讯模组,所述无线通讯模组分别与所述无线通讯接受模块、以太网络连接。
进一步地,所述无线通讯模组为USB3.0通讯模组。
上述技术方案至少具有如下有益效果:本发明通过采用以太网络以及设置在LED显示屏上的图像拼接叠放缩放处理器,在图像拼接叠放缩放处理器上设有无线通讯模组,将无线通讯模组分别与无线通讯接受模块、以太网络连接,图像全部以流媒体形式直接到达LED显示屏,无需前端的拼接器、发送器、以及接收器,且传至LED显示屏的信号数量不再受限于拼接器输入端口的数量,图像到达LED显示屏后方后,通过USB3.0接口以原图往下发送,无需多次图像采集和封装的过程,系统大大简化,图像的损失大量降低,且延时大量减小。
附图说明
图1是本发明LED显示屏一体化显示系统的原理框图。
具体实施方式
需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。下面结合附图对本发明做进一步描述。
如图1所示,本发明的LED显示屏一体化显示系统包括LED显示屏1,在LED显示屏1上设有至少一块LED灯板2,在LED灯板2上设有驱动板3,在驱动板3上设有无线通讯接受模块4,还包括以太网络5以及设置在LED显示屏1上的图像拼接叠放缩放处理器6,在图像拼接叠放缩放处理器6上设有无线通讯模组7,将无线通讯模组7分别与无线通讯接受模块4、以太网络5连接,其中,无线通讯模组7为USB3.0通讯模组。
工作时,图像信息通过以太网络5直接传输给图像拼接叠放缩放处理器6,图像全部以流媒体形式直接到达LED显示屏,无需前端的拼接器、发送器、以及接收器,且传至LED显示屏的信号数量不再受限于拼接器输入端口的数量,LED显示屏各模组之间,将USB3.0接口创新应用于新系统的视频信号往下发送,总带宽可达10G,USB3.0接口便宜且易于获得;USB3.0线缆成本低廉且易于采购;原USB3.0接口中的USB2.0差分对拆分为单端发送和接收,用于下发系统参数、视频参数、裁剪量和上报模组参数如工作情况、温度等数据。图像到达LED显示屏后方后,即以PCIE方式(高速串行计算机扩展总线标准),通过高速USB3.0接口以原图往下发送,无需多次图像采集和封装的过程,系统大大简化,图像的损失大量降低,且延时大量减小。
以上所述是本发明的具体实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也视为本发明的保护范围。
