Abstract: A touch input device capable of detecting a pressure of a touch on a touch surface may be provided. The touch input device includes: a display panel; a substrate disposed under the display panel; and a pressure sensing unit. The pressure sensing unit includes a pressure sensor and a reference pressure sensor. When a pressure is applied to the touch surface, the display panel is bent. Electrical characteristics detected at the pressure sensor change by the bending of the display panel. A magnitude of the pressure applied to the touch surface is calculated based on a difference between a reference electrical characteristic calculated from electrical characteristics detected at the reference pressure sensor and the detected electrical characteristic calculated from the electrical characteristics detected at the pressure sensor.

Abstract: A terminal for checking a security request level of a fingerprint verification request is provided. The terminal includes a fingerprint recognition sensor configured to acquire a fingerprint image; and a controller configured to check a security request level of a fingerprint verification request when the fingerprint verification request is received, to determine an verification level depending on the security request level, and to perform fingerprint verification in a manner corresponding to the verification level by using the fingerprint image. The controller controls the fingerprint recognition sensor to acquire a fingerprint image of a first level when the security request level is less than or equal to the security request level of a previous verification request that has been completed before the fingerprint verification request, and an elapsed time from the previous verification request is within a threshold time.

Abstract: A touch input device is disclosed that may comprise a display panel and/or a touch sensor. The touch sensor may include a driving electrode and/or a receiving electrode that may be disposed on the display panel and/or inside the display panel. The touch input device may comprise an electrode pattern that may be disposed on a bottom surface of the display panel. The touch input device may comprise a controller that may be configured to provide a first driving signal to the driving electrode of the touch sensor. The controller may be configured to receive a touch detection signal from the receiving electrode of the touch sensor. The controller may be configured to detect a touch position, perhaps for example based on the touch detection signal. The controller may be configured to provide a second driving signal different from the first driving signal to the electrode pattern.
