ELECTRONIC DEVICE INCLUDING FINGERPRINT SENSOR
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.
TOUCH INPUT DEVICE AND DISPLAY DEVICE USING THE SAME
A touch input device includes a communication module receiving external light characteristic information. A code detector emits infrared light and receives infrared light reflected from a display panel to detect code patterns of the display panel. A light emitting driver controls an infrared light emission operation of the code detector. A code processor modulates an emission control signal so that an infrared light emission characteristic of the code detector is changed according to a change in the external light characteristic information and controls driving of the light emitting driver.
Position detection method, position detection device, and display device
Position detection methods and systems are disclosed herein. The position detection method of detecting a position in an operation surface pointed by a pointing element includes obtaining a first taken image with the first infrared camera, obtaining a second taken image with the second infrared camera, removing a noise component from the first and second images converting the first and second taken into converted images without the noise component, forming a difference image between the first converted taken image and the second converted taken image, extracting a candidate area in which a disparity amount between the first converted taken image and the second converted taken image is within a predetermined range, detecting a tip position of the pointing element from the candidate area, and determining a pointing position of the pointing element and whether or not the pointing element had contact with the operation surface based on the detecting.
Systems and methods for automated interaction with a touch-screen device
Systems and methods for automated interaction with a touch-screen device are described. A system for automated interaction with a touch-screen device may include at least one optical sensor configured to sense at least a first portion of a touch-screen of the touch-screen device; at least one solenoid including an end effector that is tactilely detectable by the touch-screen, wherein operation of the at least one solenoid causes the end effector to tactilely engage with a second portion of the touch-screen; and a controller that is operatively connected to the at least one optical sensor and the at least one solenoid, and that is configured to operate the at least one solenoid in response to detecting a predetermined characteristic of the touch-screen via the at least one sensor.
OPTICAL DEVICE
The application concerns an optical device including: a primary fan-out waveguide; at least one secondary fan-out waveguide; a fan-out optical coupler for coupling a light beam between the primary fan-out waveguide and the secondary fan-out waveguide; and at least one bus waveguide associated with the at least one secondary fan-out waveguide and different from each secondary fan-out waveguide; wherein a reflecting and coupling structure connecting the secondary fan-out waveguide and the bus waveguide.
Displays With Optical Edge Sensors
A display may have an array of light-emitting pixels that display an image in an active area of the display. These light-emitting pixels may be visible light pixels such as red, green, and blue thin-film organic light-emitting diode pixels. The display may also have a border region that runs along a peripheral edge of the active area. The border region may be free of pixels that display image light, whereas the active area may be free of light detectors. A non-optical touch sensor such as a capacitive touch sensor may overlap the active area to gather touch input from the active area. The non-optical touch sensor may not overlap any portion of the border region. In the border region, an optical sensor formed from infrared light-emitting pixels and infrared light-sensing pixels or other optical sensing circuitry may serve as an optical touch sensor.

A display system for sensing a finger of a user applied to the display system includes a display panel; a sensor for sensing the finger; a sensing light source configured to emit a first light having a first wavelength W1; and a reflective polarizer disposed between the display panel and the sensor. For a substantially normally incident light, an optical transmittance of the reflective polarizer versus wavelength for a first polarization state has a band edge such that for a first wavelength range extending from a smaller wavelength L1 to a greater wavelength L2 and including W1, where 30 mn≤L2−L1≤50 nm and L1 is greater than and within about 20 nm of a wavelength L3 corresponding to an optical transmittance of about 50% along the band edge, the optical transmittance has an average of greater than about 75%.
CONTROLLING OPTICAL SENSORS IN A DISPLAY
Interference of light-sensing elements of a display system by light-emitting elements of the display system is reduced. An emission schedule is determined for the one or more light-emitting elements in an optical sensing region of the display system to include one or more emission periods and one or more emission-off periods, wherein the one or more light-emitting elements emit light within the optical sensing region during an emission period and do not emit light within the optical sensing region during an emission-off period. A synchronization signal is generated to drive the one or more light-emitting elements of the display system. Light sensing by the one or more light-sensing elements in the optical sensing region is triggered, based on the emission schedule, wherein the sensing by the light-sensing elements in the optical sensing region is triggered to be performed during the emission-off period.
Display screen module, terminal device and fingerprint identification method
A display screen module includes a display screen and a fingerprint identification unit. The display screen includes a front display area and a side display area. The side display area at least partially covers the fingerprint identification unit, and the fingerprint identification unit is configured to obtain a fingerprint image. As the fingerprint identification unit is at least partially covered by the side display area, it can reduce or even needs not to occupy under-screen space of the front display area, and arrangement of the components can be optimized. When the user directly holds the side display area to which the fingerprint identification unit corresponds, fingerprint unlocking can be executed directly, which brings new fingerprint unlocking experience to the user, and also makes the unlocking process easier.
DISPLAY APPARATUS
Provided is a display apparatus. The display apparatus comprises a display panel including a front portion including a display area and a non-display area, a bending portion, and a back portion bent from the bending portion and disposed rearward of the front portion; a plurality of touch routing lines disposed in the non-display area and electrically connected to a plurality of touch electrodes disposed in the display area; and a plurality of auxiliary lines disposed below the plurality of touch routing lines, in which the plurality of touch routing lines are discontinuously disposed on the bending portion while having a predetermined length.
