TOUCH DISPLAY PANEL AND TOUCH DISPLAY DEVICE

The invention discloses a touch display panel and a touch display device. The present disclosure relates to touch display panels and touch display devices. More specifically, the touch display panelsand touch display devices provided are capable of performing display driving and touch driving simultaneously or together through a ground modulation scheme. Further, by separating a power source fordriving a display controller D-CTR from a power source for driving a touch controller T-CTR, and controlling respective power sources independently, it is possible to reduce power consumption. Also, by enabling a power source for driving a ground modulation circuit to be variable, it is possible to provide functions based on touch sensing under a condition of reduced power consumption. 触摸显示面板和触摸显示装置。本公开涉及一种触摸显示面板和触摸显示装置。更具体地说，所提供的触摸显示面板和触摸显示装置能够通过接地调制方案同时或一起执行显示驱动和触摸驱动。此外，通过将用于驱动显示控制器D-CTR的电源与用于驱动触摸控制器T-CTR的电源分离，并独立地控制各个电源，可以降低功耗。而且，通过使用于驱动接地调制电路的电源可变，可以在降低功耗的条件下提供基于触摸感测的功能。
