Display substrate and display device

The utility model provides a display substrate and a display device. The display substrate comprises a first chip configured to output a target touch signal based on an initial touch signal in response to the received initial touch signal from the touch display panel; the second chip is electrically connected with the first chip and is configured to output a touch control data signal to the main control unit based on a target touch control signal, respond to an image data signal received from the main control unit and output a time sequence control signal and a display data signal based on the image data signal; wherein the first chip is further configured to receive a time sequence control signal and a display data signal, and output a gate driving signal and a data voltage signal to the touch display panel.
