Touch display chip, touch display device, terminal equipment and display driving method

The invention discloses a touch display chip, a touch display device, terminal equipment and a display driving method.The display driving method comprises the steps that image data are received, and multiple paths of source electrode data signals are provided according to the image data; detecting whether the multi-path source electrode data signal output is a high-noise picture or not; and adjusting the driving mode of the display driving circuit according to the detection result. The driving mode of the display driving circuit is adjusted for a high-noise picture, so that the overall jump of data signals in the source data lines is reduced, and the noise of the touch electrode layer is reduced. 本发明公开了一种触控显示芯片、触控显示装置、终端设备及显示驱动方法，其中，显示驱动方法包括：接收图像数据，并根据所述图像数据提供多路源极数据信号；检测所述多路源极数据信号输出是否为高噪声画面；根据检测结果调整显示驱动电路的驱动模式。通过对高噪声画面调整所述显示驱动电路的驱动模式，以减少源极数据线中的数据信号整体跳变，从而降低触控电极层的噪声。
