AI Technical Summary
Technical Problem
Existing foldable display devices struggle to effectively control the touch functionality of each touch area under different display states, resulting in high circuit complexity, high cost, and poor reliability.
Method used
By splitting the touch signal line into sub-touch signal lines and using a multiplexing circuit to connect each sub-touch area, the corresponding sub-touch function is activated according to the display status, and screen split control is achieved using only one touch chip.
Benefits of technology
It simplifies the structure of foldable display devices, reduces wiring space, lowers the complexity of control circuits, improves the reliability of display devices, and reduces manufacturing costs.

Abstract
本发明公开了一种折叠显示模组、折叠显示装置和触控驱动方法，其中一实施例的折叠显示模组包括：沿至少一个折叠轴折叠的外折式触控显示面板，划分为多个子触控区，包括：多个第一触控电极和连接其的第一触控信号线、多个第二触控电极和连接其的第二触控信号线，延伸方向与折叠轴垂直的触控信号线被拆分为分别连接不同子触控区的各触控电极的多个子触控信号线；与被拆分的触控信号线对应的多个复用电路，每个复用电路分别连接一个被拆分的触控信号线的多个子触控信号线，每个复用电路响应于折叠显示模组的显示状态将对应的子触控信号线与触控芯片连接的触控传输线连接以实现对应的子触控区的触控功能，从而有效简化折叠显示装置的结构并降低成本。
