Data transmission method, chip, controller and display device

A data transmission method, which is applied to a controller in a display device, wherein the display device comprises the controller, a plurality of driving chips, and an in-cell touch display panel;

• and the method comprises:
• receiving return data sent by a target driving chip, the return data comprising state data and working mode data of the target driving chip, wherein the working mode data is configured to indicate a working mode of the target driving chip, the working mode is configured to indicate a current data processing rate of the target driving chip and comprises a low-speed working mode or a high-speed working mode, the data processing rate in the high-speed working mode is higher than that in the low-speed working mode, and the target driving chip switches its working mode according to an amount of data that needs to be processed currently;
• wherein the target driving chip is one of the plurality of driving chips, and the target driving chip is respectively connected to the controller and the in-cell touch display panel;
• the return data is sent by the target driving chip to the controller after the target driving chip receives the state data acquired by the in-cell touch display panel, the state data being configured to reflect a working state of the in-cell touch display panel and including touch data.
