Touch screen and fingerprint identification realizing device and terminal equipment

The disclosure relates to a touch screen and a fingerprint identification realizing device and terminal equipment; a fingerprint identification sensor comprises a plurality of sub-sensors, is positioned below a cover plate glass, occupies partial the area below the touch screen, and is used for respectively sending signals formed by each sub-sensor to a fingerprint identification circuit when an all-in-one switch is in an open circuit; when the all-in-one switch is closed, the all-in-one switch can combine all signals formed by each sub-sensor into a touch control signal, and the touch control signal is sent to a touch screen circuit; the fingerprint identification circuit is used for processing the signals detected by each sub-sensor; the touch screen circuit is used for determining whether to generate a touch operation or not according to the combined touch control signal; the common fingerprint identification sensor can realize fingerprint identification and touch screen functions, thus improving electronic equipment integrated level, realizing compatibility between capacitance touch control and fingerprint identification in a display zone, and increasing user operation conveniences.
