显示面板以及显示终端
【技术领域】
本发明涉及显示领域，特别是涉及一种显示面板以及显示终端。
【背景技术】
柔性电路板，简称软板，又称柔性线路板或软性线路板。柔性电路板是以聚酰亚胺或聚酯薄膜为基材制成的一种具有高度可靠性，绝佳的可挠性印刷电路板。能够提供优良的电性能，满足更小型和更高密度安装的设计需要，也有助于减少组装工序和增强可靠性。柔性电路板是满足电子产品小型化和移动要求的唯一解决方法。可以自由弯曲、卷绕、折叠，可以承受数百万次的动态弯曲而不损坏导线，可依照空间布局要求任意安排，并在三维空间任意移动和伸缩，从而达到元器件装配和导线连接的一体化。柔性电路板可大大缩小电子产品的体积和重量，适用电子产品向高密度、小型化、高可靠方向发展的需要。
由于显示终端在工作过程中会产生许多不同频率的噪声，而这些噪声会容易对显示讯号造成很大的干扰，为了缓解消除这些干扰，往往需要在柔性电路板上贴合EMI层，以起到屏蔽噪声干扰的作用。
