Abstract:
A driver chip including a receiving structure, a shielding structure, and a touch control circuit is provided. The receiving structure can receive a touch sensing signal. The shielding structure can be disposed aside the receiving structure. The shielding structure can shield at least one parasitic capacitor coupled to the receiving structure. The touch control circuit can be connected to the receiving structure and configured to receive the touch sensing signal. An electronic device including a driver chip is also provided.
