  • Touch control apparatus with fingerprint identification function
    Patent number: 10360427
    Abstract: A touch control apparatus with fingerprint identification function includes a substrate body with a visible region, a plurality of first primary electrodes, a plurality of second primary electrodes, and a fingerprint identification region located in the visible region. The first primary electrodes and the second primary electrodes are mounted in the visible region for sensing a touch coordinate when an object touches on the visible region. The first secondary electrodes are crossly arranged and insulated from the second secondary electrodes in the fingerprint, identification region. Further, a part of the first primary electrodes and the second primary electrodes are extended to the fingerprint identification region. When a user performs a fingerprint identification function, all electrodes in the fingerprint identification region are used to detect and identify the user's fingerprint.
