  • Publication number: 20240012510
    Abstract: The driving circuit of the display includes a timing controller. The timing controller is coupled to a general purpose input/output (GPIO) pin of the touch driver. The timing controller receives an instruction signal via the GPIO pin of the touch driver. The timing controller starts a detection period according to a first edge switched from a first voltage level to a second voltage level of the instruction signal. The timing controller detects a number of pulse signals of the instruction signal, and determines a current operating status of the touch driver according to the number of pulse signals of the instruction signal during the detection period. The timing controller determines that the current operating status of the touch driver is one of touch operation type statuses according to the number of pulse signals of the instruction signal during the detection period being a default number.
