Abstract:
Provided is a display module, including: a display panel having a first binding area and a flexible circuit board having a second binding area. First binding pins provided in the first binding area are correspondingly bound to second binding pins provided in the second binding area. First and second test boards are provided in the first and second binding areas, respectively, and the first and second test boards overlap while being insulated from each other. A driving chip fixed to the flexible circuit board includes a touch sensing pin and a touch driving pin. The touch driving pin is configured to output a touch driving signal and the touch sensing pin is configured to receive a touch sensing signal. One of the first test board and the second test board is electrically connected to the touch sensing pin, and the other one is electrically connected to the touch driving pin.
