  • Publication number: 20220029062
    Abstract: A light-emitting assembly with improved illumination includes a first substrate, a light guide layer, light emitters, a touch sensor, a first reflective layer, and a second reflective layer. The first substrate defines a light-transmitting area. The light emitters are in the light guide layer. The light emitters emit light to illuminate the light-transmitting area. The touch sensor is opposite to the light-transmitting area. The first reflective layer is between the first substrate and the light guide layer and defines an opening aligned with the light-transmitting area. The second reflective layer is on a side of the light guide layer away from the first substrate. An electronic device using the light-emitting assembly and a method for making the light-emitting assembly are also disclosed.

  • Patent number: 11231820
    Abstract: A touch sensing structure with improved illumination includes a first substrate, a decoration layer, a light-shielding layer, a light-emitting element, a pressure-sensitive element, a first reflective layer, and a second reflective layer. The pressure-sensitive element is farther away than the light-emitting element from the first substrate. The decoration layer shows a function icon. The light-emitting element emits light to illuminate the function icon. When the first substrate is pressed, the touch sensing structure determines a magnitude of the pressing force by detecting a change in the resistance or voltage value of the pressure-sensitive element. If the pressing force reaches a specific value, the function identified by the function icon is executed, otherwise no function is executed.

  • Patent number: 10605786
    Abstract: Ultrasonic wave sensing device includes a reading transistor, an ultrasonic wave transducer, and an input circuit. The reading transistor includes a first node, a second node, and a control node, wherein the first node receives a reference voltage, the second node couples with a reading node, and the control node couples with a first signal node. The ultrasonic wave transducer couples between the first signal node and a first input node, and receives a first control signal from the first input node. The input circuit couples between the first signal node and a second input node, and receives a second control signal from the second input node. The ultrasonic wave transducer generates an ultrasonic wave according to the first control signal and the second control signal, and outputs a sensing signal to the control node according to a reflected sound wave.
