In the touch display panel, a frame is provided with a first accommodation space, a first accommodation slot, and a second accommodation slot; a display pane disposed in the first accommodation space, infrared emitting modules disposed in the first accommodation slot and at a periphery of a light-emitting side of the display panel; and infrared receiving modules disposed in the second accommodation slot and at the periphery of the light-emitting side of the display panel.

A sensing system comprising an emitter configured to emit electromagnetic radiation, a detector configured to detect electromagnetic radiation and an electronic component configured to interact with a circuitry of the sensing system. The electronic component is located at least partially between the emitter and the detector. The electronic component reduces an amount of electromagnetic radiation propagating from the emitter to the detector. The electronic component advantageously reduces the unwanted detection of electromagnetic radiation that would otherwise propagate directly from the emitter to the detector without leaving the sensing system, thereby reducing a measurement noise and improving an accuracy of the sensing system. The sensing system may form part of a time-of-flight sensing system or a proximity sensing system. The sensing system may form part of an electronic device such as a mobile phone.

An electronic watch includes a housing defining a side surface of the electronic watch, a transparent cover coupled to the housing and defining a front surface of the electronic watch, an image-sensing element, and a crown extending from the side of the housing and defining an imaging surface. The crown may include a light-directing feature configured to direct, onto the image-sensing element, an image of an object in contact with the imaging surface.

A detection device includes: optical sensors; switching elements, gate lines, and signal lines corresponding to the optical sensors; a detection circuit that is supplied with signals from the optical sensors through the signal lines; and a signal line selection circuit for switching a coupling state between the signal lines and the detection circuit. A drive signal is supplied to the gate lines row by row to bring the switching elements belonging to a predetermined row into a coupled state. The signal line selection circuit couples the signal lines to the detection circuit column by column in a predetermined order in a reading period of the predetermined row. A reset potential is supplied to the optical sensors and the signal lines belonging to the predetermined row after completion of the reading period of the predetermined row and before start of the reading period of a row next to the predetermined row.

A method for detecting an operating input performed by a finger involves detecting various contact points of a contour of the finger using a sensor system on a sensor surface. The sensor system includes at least one transmitting unit for transmitting a signal to the finger and at least one receiving unit for receiving a signal reflected by the finger. A surface vibration is introduced into the sensor surface by at least one actuator, the surface vibration changes the frictional resistance between the finger and the sensor surface as a function of the changing contact points of the contour of the finger.

A touch input display system includes a display device and a touch input device. The display device includes a display, a frame enclosing the display, and a light receiver that receives infrared light emitted from an external operation device. The touch input device has a touch inputter and a frame body that encloses the touch inputter. The touch input device is attached to the display such that the frame body overlaps on a front side of the frame. The frame body has an infrared light guide. The infrared light guide guides infrared light emitted from the external operation device to the light receiver.

According to certain embodiments of the disclosure, an electronic device comprising: a support member having a first hole; a first fingerprint sensor disposed in the first hole; and a non-conductive injection molding material integrally joining the support member and the first fingerprint sensor.

An electronic device having a noncontact input function is provided. The electronic device includes a display device and an input device and is capable of performing an input operation even without contact. The display device includes a light-emitting device and a light-receiving device in a display portion. The input device includes a light source. The light-receiving device has a function of detecting light emitted from the light source included in the input device. Infrared light that has substantially no spectral luminous efficacy is used as the light emitted from the light source included in the input device. Therefore, even irradiation of the display portion with the light at high luminance does not affect visual recognition of the display. This structure enables a noncontact input operation with respect to the display device.
