Abstract:
In the invention, a fingerprint driving circuit, a fingerprint sensing device, an electronic apparatus, and an operation method of the fingerprint sensing device are provided. By keeping fingerprint sensing lines in a non-fingerprint sensing region in an electrically non-floating state, flash phenomenon in a display panel may be avoided.
