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 touch position and touch pressure may be provided that includes: a display panel; a touch sensor including a touch electrode which is used to detect the touch position; and a pressure sensor including a pressure electrode which is used to detect the touch pressure. A harmonic frequency and a frequency of a horizontal synchronization signal, which is used to drive the display panel, do not exist within a first gap from a touch pressure sensing frequency which is used to drive the pressure sensor. The first gap may be 5 kHz.
