    Abstract: A touch input device and a method for measuring a capacitance of the touch input device may be provided. The touch input device includes: a display panel; a pressure sensor which is disposed under the display panel; a reference potential layer which is disposed apart from the pressure sensor; and a controller which receives an output voltage from the pressure sensor and calculates a first capacitance value, and calculates a second capacitance value by removing a parasitic capacitance value from the first capacitance value. The controller receives the output voltage from the pressure sensor in a state where the reference potential layer is floating, and calculates the parasitic capacitance value.

    Abstract: A touch input device may be provided that includes a cover layer including a display area and an input area; a display panel which is disposed under the display area; and a pressure sensing unit which is disposed under the display panel and is disposed at a position adjacent to the input area. The pressure sensing unit includes a pressure sensor. When a pressure is applied to the cover layer, the cover layer and the display panel are bent. Electrical characteristics of the pressure sensor change due to the bending of the cover layer and the display panel. When the pressure is applied to the input area, a magnitude of the pressure applied to the input area is detected by the electrical characteristics of the pressure sensor.

    Abstract: In one embodiment, a control method for a touch sensor panel is disclosed. The method includes obtaining touch information on the touch sensor panel from which an electrical signal outputted is changed according to a touch, and detecting at least one valid touch from the touch information. It is determined that a valid touch of the at least one valid touch is included in a palm touch group by (a) detecting a palm touch, which meets a palm touch condition, among the at least one valid touch, and (b) determining that the detected palm touch and the valid touch occur within a predetermined time period. A display unit displays an input corresponding to each of the at least one valid touch other than the valid touch included in the palm touch group.

    Abstract: In one embodiment, a touch input device capable of detecting a pressure and a position of a touch on a touch surface is disclosed. The touch input device includes a cover layer of glass, a display panel, and a touch sensor panel fully laminated on the display panel. The device further includes a substrate spaced apart from the display panel and separating the display panel from a circuit board and a battery for operation of the touch input device, and a pressure electrode disposed between the display panel and the substrate. Drive electrodes are formed on one side of an insulation layer, and receiving electrodes are formed on the other side of the insulation layer. Further, a distance between the substrate and the display panel is maintained by a double adhesive tape formed on edge portions of the substrate and the display panel when no pressure is applied.

    Abstract: A touch input device for detecting a touch pressure including: a display panel; a pressure sensing unit to detect the touch pressure; a pressure sensor controller connected to the pressure sensing unit; and a first PCB. The pressure sensor is formed on the display panel. A first connection line pattern having a first access portion formed at one end is formed on the first PCB. The other end is connected to the pressure sensor controller. A conductive trace which extends from the pressure sensor and includes a second access portion formed on one end is formed on the display panel. The first access portion of the first connection line pattern and the second access portion of the conductive trace are connected to each other by a conductive adhesive member disposed between the first access portion of the first connection line pattern and the second access portion of the conductive trace.

    Abstract: In one embodiment, a touch input device capable of detecting a pressure of a touch on a touch surface includes a display panel and an electrode disposed under the display panel. An electrical characteristic detected at the electrode is changed by the bending of the display panel. A magnitude of the pressure applied to the touch surface is detected according to the change amount of the electrical characteristic. The display panel includes a first area and a second area. A pressure detection sensitivity of the first area is higher than a pressure detection sensitivity of the second area. When the first area and the second are bent to the same degree, a chance amount of the electrical characteristic detected when a pressure is applied to the second area is greater than a change amount of the electrical characteristic detected when a pressure is applied to the second area.
