Description

触控显示面板及显示装置 技术领域
本申请涉及显示技术领域，具体涉及一种触控显示面板及显示装置。
 背景技术
目前，触控技术已广泛地应用于各种电子装置的显示设备中，以便于使用者利用触控方式操控该电子装置的运行。此外，随着信息与通讯技术的进步，具有无线通信功能的电子装置例如移动电话、平板计算机、便携计算机已成为人们日常生活中不可或缺的配备。一般而言，具有无线通信功能的电子装置需包括天线以及无线信号处理模块，其中天线设置为无线信号收发组件，且通常以外加的方式设置于电子装置的电路板上或壳体的内表面。
然而，随着电子装置逐渐朝向轻薄及高密集度的趋势发展，当前技术的触控显示面板由于触控显示屏幕不具备天线的发射及接收功能，需要将天线组件集成在中框，并设计单独的天线模块，其中，中框需要采用分段式设计以便集成天线，这样将占据电子装置内部的空间，影响内部线路布局，使电子装置的厚度无法进一步降低，且将增加电子装置的组装步骤与材料成本。
因此，亟需一种触控显示面板及显示装置以解决上述技术问题。
