Provided are a touchscreen and a fingerprint recognition apparatus and a terminal device; a fingerprint recognition sensor (21) comprises a plurality of sub-sensors (42); the fingerprint recognition sensor is located beneath a cover panel glass, partially occupies a region below a touchscreen, and is used, when an all-in-one switch is open, for transmitting to a fingerprint recognition circuit (22) the signals detected and produced by the sub-sensors; when the all-in-one switch (23) is closed, the signals detected and produced by the sub-sensors are combined into a touch control signal and transmitted to the touchscreen circuit (24) by means of the all-in-one switch; the fingerprint recognition circuit is used for processing the signals detected and produced by the sub-sensors; the touchscreen circuit is used for determining, according to the combined touch control signal, whether to generate a touch control operation. The solution described above is capable of using a shared fingerprint recognition sensor to accomplish fingerprint-recognition and touchscreen functions; the degree of integration of the electronic device is increased, while at the same time, compatibility of capacitive touch control and fingerprint recognition within a display region is achieved, and operation by a user is made more convenient. |
