In this way, since two differential signal lines are provided between the target driving chip and the controller, the transmission and reception of signals are independent of each other and do not affect each other, and there will be no conflict in timing, so that real-time transmission of return data can be achieved.
- the embedded touch display panel is directly transmitted to the target drive chip after each acquisition of the status data. After the target drive chip generates the return data based on the status data, it is directly transmitted to the controller through the first differential signal line. This process can be To ensure the timeliness of the status data, the controller can obtain the status data and process it in time.
- the differential signal line includes two signal lines for signal transmission through differential transmission.
- differential transmission is a signal transmission technology, which is different from the traditional method of one signal line (the signal line can be a clock signal line) and a ground line; differential transmission is a signal transmission on both signal lines
- the signals transmitted on these two signal lines have the same amplitude and opposite phases.
- the signals transmitted on these two signal lines are differential signals.
