A display module and system applications including a display module are described. The display module may include a display substrate including a front surface, a back surface, and a display area on the front surface. A plurality of interconnects extend through the display substrate from the front surface to the back surface. An array of light emitting diodes (LEDs) are in the display area and electrically connected with the plurality of interconnects, and one or more driver circuits are on the back surface of the display substrate. Exemplary system applications include wearable, rollable, and foldable displays.

An electronic device, an input/output apparatus and an input/output method therefor are disclosed. The electronic device includes an input/output controller, a first projector component, a second projector component and a detector component. The input/output controller generates a first projection signal for an output interface and a second projection signal for an input interface. The first projector component projects the output interface according to the first projection signal. The second projector component projects the input interface according to the second projection signal. The detector component detects an input signal in the projected input interface, and transmits the detected input signal to the input/output controller as an input signal for the electronic device. By implementing input/output in a manner of projection, an input/output interface of a desired size is provided while the input/output apparatus of the electronic device is miniaturized.

A fingerprint identification device, a touch display panel and a method for controlling fingerprint identification are provided in embodiments of the disclosure. The fingerprint identification device includes: a photoelectric sensor; and an optical waveguide, arranged on a touch substrate at another side, and configured to be in touch with a fingerprint, and comprising waveguide material portions and medium material portions, each of the waveguide material portions and each of the medium material portions being spaced apart from each other; and a light irradiating into the waveguide material portions is delivered to the surface(s) of the waveguide material portions facing away from the touch substrate after total reflections at interfaces between the medium material portions and the waveguide material portions. If a portion of valleys of the fingerprint gets in touch with the surface(s), since the portion of valleys is filled with air, then the light returns by total reflection so as to be identified by the photoelectric sensor; if a portion of ridges of the fingerprint gets in touch with the surface(s), the light at the portion of ridges is reflected by diffuse reflection so as not to be reflected back for identification by the photoelectric sensor. The fingerprint identification in embodiments of the disclosure is adapted to various display devices.

A display device is provided. The display device includes a front frame, a rear cover, a display panel, a plurality of sensors and at least one adjusting mechanism. The front frame has an opening. The front frame and the rear cover are fixed to form an accommodation space. The display panel, disposed in the accommodating space, has a display surface exposed to the opening. A plurality of sensors are disposed on the front frame and configured to receive and emit an optical signal above the display surface. At least one adjusting mechanism is disposed on the rear cover and configured to adjust a deformation amount of the front frame to maintain the sensors at a predetermined emitting position and a receiving position.

Touch detection may include determining, based on data from an IMU on a first device that monitors movement of a touching object, a touch event, wherein the touch event indicates contact between the touching object and a surface, obtaining a depth image captured by a second device, comprising a touch image, determining a touch point of the object based on the touch image, and providing a response based on the touch point of the object and the touched surface.

The present disclosure provides a touch device. The touch device includes a frame, a substrate, an infrared emitting unit, and an infrared receiving unit. The infrared emitting unit and the infrared receiving unit are disposed on the frame and located above the substrate. The touch device also includes: a connecting block which is connected at an edge region on a lower surface of the substrate, and an adjusting member which connects the connecting block and the frame and adjusts a lateral tensile force applied by the adjusting member to the substrate. The touch device of the present disclosure ensures the flatness of the substrate by the connecting block in cooperation with the adjusting member, avoiding the influence of the substrate on the infrared light, and has a simple structure and is convenient to assemble.

A user input device (202), for providing an input to an elevator controller is disclosed. The user input device (202) includes a plurality of input regions (204A-204F) each of which correspond to a different input command; and a single touchless sensor (216) arranged to detect the presence of an object in any of the plurality of input regions (204A-204F).

Examples of systems are described herein. In some examples, a system includes a projector, a camera, a touch sensitive mat, and a computing device. In some examples, the computing device may receive a first input from the camera corresponding to a first layer, a second input from the touch sensitive mat corresponding to a second layer, and a third input from a collaborating remote computing device corresponding to a third layer. In some examples, the computing device may render collaborative display data based on the first input, the second input, the third input, and a layer filter. In some examples, the collaborative display data is presented by the projector.

An electronic device is provided. The electronic device includes a display including a sensing area, a sensing layer below the display, the sensing layer including a plurality of openings, and a biometric sensor for receiving light emitted from the sensing area and reflected from an external object. The sensing layer includes first signal line sets, each including a plurality of first signal lines extending in a first direction, repeatedly arranged and spaced from each other by a specified spacing, and second signal line sets, each including a plurality of second signal lines extending in a second direction intersecting the first direction, repeatedly arranged and spaced from each other by a specified spacing. At least one of the first or second signal lines extends in and along a portion of the sensing layer between adjacent ones of the openings, which are positioned in a path along which light is reflected from the object and is then incident on the biometric sensor.

Object of the present invention are a method and a system for monitoring a user's attention distribution in the course of a digital image exploration, adapted to produce feedback that give the user himself an indication of the efficacy of the exploration performed, even on the basis of the relevance that the various zones of the image have in relation to a certain goal, relevance that can possibly be determined by an expert system responsible for examining the image as a function of the above-mentioned objective.
