Abstract: A touch input device may be provided that includes: a first cover layer; a spacer layer; a display panel which includes a first substrate layer and a second substrate layer disposed under the first substrate layer; a first electrode and a second electrode which are disposed between the first substrate layer and the second substrate layer; and a third electrode and a fourth electrode which are disposed on the display panel. At least one of the first electrode and the second electrode is used to drive the display panel. A touch position is detected based on a capacitance which changes as an object approaches a touch sensor including at least one of the first electrode, the second electrode, the third electrode, and the fourth electrode and which is detected from the touch sensor. A touch pressure is detected based on a capacitance which is changed by change of a distance between the object and a pressure sensor including at least one of the first electrode, the second electrode, the third electrode, and the fourth electrode and which is detected from the pressure sensor. The spacer layer is disposed between the first cover layer and the pressure sensor.

Abstract: A display device having a sensor coupled thereto according to one embodiment of the present invention comprises: a cover layer; a display panel disposed below the cover layer; an optical layer disposed below the display panel; and an image sensor disposed below the optical layer. The optical layer includes: a microlens array layer including a plurality of microlenses; and an aperture layer which is disposed below the microlens array layer and includes holes each spaced apart from the microlenses by a focal length of the microlens. According to one embodiment of the present invention, a distance from a fingerprint to a fingerprint sensor can be greatly decreased in comparison with a conventional technology. In addition, deterioration of fingerprint image quality due to scattered light can be reduced.

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 module; and a pressure sensor which is disposed at a position where a distance between the pressure sensor and a reference potential layer is changeable according to the touch on the touch surface. The distance is changeable according to a pressure magnitude of the touch. The pressure sensor outputs a signal including information on a capacitance which is changed according to the distance. The pressure sensor includes a plurality of electrodes to form a plurality of channels. The pressure magnitude of the touch is detected on the basis of a change amount of the capacitance detected in each of the channels and an SNR improvement scaling factor assigned to each of the channels.
