Abstract: A display panel and a driving method thereof are provided, including a time schedule controller and at least one driver integrated circuit (driver IC). Pulse width modulation (PCM) data between the time schedule controller and the driver IC is transmitted in a decoded manner, and pulse amplitude modulation (PAM) data is transmitted in an undecoded manner, reducing a transmission rate between the time schedule controller and the driver IC, and thereby reducing or eliminating risks of electromagnetic interference (EMI). Furthermore, using this transmission method can reduce the number of latches used in the driver IC.
