1. A touch control method, configured to control a touch operation mode and a fingerprint recognition mode, the method comprising:
providing a touch device, wherein the touch device comprises a plurality of sensing electrodes;
determining whether an object is located in a sensing distance of the sensing electrodes;
when result of the determining is yes, detecting a sensing group of the sensing electrodes sensing the object;
determining whether a sensing area of the sensing group is greater than or equal to a first area and less than or equal to a second area;
determining whether a sensing time of a predetermined proportion of the sensing electrodes in the sensing group is greater than or equal to a predetermined time;
if the sensing area is greater than or equal to the first area and less than or equal to the second area, and if the sensing time is greater than or equal to the predetermined time, executing the fingerprint recognition mode; and
if the sensing area is less than the first area or greater than the second area, or if the sensing time is less than the predetermined time, executing the touch operation mode.
