Display device, heart rate monitoring system and method of monitoring heart rate

A heart rate monitoring system comprising a touch display device, the touch display device comprising:

• a display module for displaying image and having a substrate being an upper component of the display module;
• a sensing electrode for sensing an electrocardio signal of a user, the sensing electrode being arranged above the substrate,
• wherein the heart rate monitoring is performed through the user touching the sensing electrode of the touch display device with a finger,
• wherein the sensing electrode comprises an array of sensing electrode units, and the touch display device further comprises an array of switching elements, each switching element of the array of switching elements corresponds to and is electrically connected with each sensing electrode unit of the array of sensing electrode units,
• wherein each switching element of the array of switching elements is configured to be turned on in response to a finger of the user touches the sensing electrode unit corresponding to the switching element, and turned off in response to the finger of the user leaves the sensing electrode unit corresponding to the switching element,
• wherein the array of sensing electrode units acts as touch electrodes during a touch period for detecting a touch position of the finger of the user.
