AI Technical Summary
Technical Problem
但定制高通道数触控芯片不仅硬件成本高，且大尺寸芯片对贴片工艺要求严苛，生产良率低；而多芯片串联方案则会大幅抬高整机成本，且电路复杂，易出现信号干扰、触控延迟、工作稳定性差等问题
Benefits of technology
本公开实施例的触控显示装置包括触控板、显示面板以及运动组件，其中，触控板的尺寸小于显示面板的尺寸，且触控板通过所述运动组件活动设置于显示面板的出光侧，其可在运动组件的带动下在平行于显示面板的平面内进行平移运动和/或旋转运动，从而利用小面积的触控板以遍历方式覆盖显示面板的整个显示区域，无需在显示面板的整面区域上铺设大面积的触控板，也无需增设多通道触控芯片或串联多个触控芯片，在实现全屏任意位置触控交互的同时，显著降低了硬件成本和电路复杂度；同时，由于大尺寸显示面板在实际使用中通常仅局部区域被利用，整面铺设触控传感器会造成触控资源长期闲置浪费，而本方案通过小面积触控板按需移动，仅在用户当前关注的局部区域提供触控功能，避免了触控资源的闲置浪费。

Abstract
The present disclosure provides a touch display device and a touch detection method. The touch display device comprises a display panel, a touch panel, and a motion assembly. The touch panel has a smaller orthographic projection area in a first plane than the display panel. The touch panel is movably arranged on the light exit side of the display panel by the motion assembly and moves in the first plane under the driving of the motion assembly. The motion comprises translational motion and / or rotational motion. The first plane is parallel to the display panel.
