FIELD: physics.
SUBSTANCE: terminal device includes a control component and a screen, and the screen includes a protective screen layer, a display component, a fingerprint detection element, and a plurality of touch signal detection elements. The fingerprint detection element and a plurality of touch signal detection elements are provided between the protective screen and the upper surface of the display component; the fingerprint detection element is provided in the free space among various touch signal detection elements; and the control component is electrically connected to the fingerprint detection element and configured to receive a fingerprint detection element detection signal, generating fingerprint data based on the fingerprint detection element detection signal, and executing the preset control instruction if the fingerprint data coincides with the fingerprint reference data.
EFFECT: increasing the reliability of the protective layer.
