  • Patent number: 11996772
    Abstract: The present invention provides a voltage control method for controlling a power supply. The voltage control method comprises the following steps: obtaining a present output voltage value associated with a present gain value; obtaining a predetermined output voltage value associated with a predetermined duty ratio; calculating a target gain value, corresponding to the predetermined duty ratio, according to a gain value formula; performing a weight calculation on the present gain value and the target gain value for generating a buffer gain value; and setting an output voltage command according to the buffer gain value. Wherein the buffer gain value is between the present gain value and the target gain value.

  • Publication number: 20240128420
    Abstract: A display panel including a circuit board, a plurality of bonding pads, a plurality of light emitting devices, and a plurality of solder patterns is provided. The bonding pads are disposed on the circuit board, and each includes a first metal layer and a second metal layer. The second metal layer is located between the first metal layer and the circuit board. The first metal layer includes an opening overlapping the second metal layer. A material of the first metal layer is different from a material of the second metal layer. The light emitting devices are electrically bonded to the bonding pads. Each of the solder patterns electrically connects one of the light emitting devices and one of the bonding pads. The solder patterns each contact the second metal layer through the opening of the first metal layer of one of the bonding pads to form a eutectic bonding.

  • Publication number: 20240088182
    Abstract: In some embodiments, an image sensor is provided. The image sensor includes a photodetector disposed in a semiconductor substrate. A wave guide filter having a substantially planar upper surface is disposed over the photodetector. The wave guide filter includes a light filter disposed in a light filter grid structure. The light filter includes a first material that is translucent and has a first refractive index. The light filter grid structure includes a second material that is translucent and has a second refractive index less than the first refractive index.

  • Publication number: 20190000260
    Abstract: A fitter kettle structure contains: a container, a lid, and a filtering device. The container includes an opening, an outlet, and a grip handle. The lid rotatably covers the opening and includes a surround section, multiple guiding holes, and a through hole. The filtering device includes a first filter unit, a connection rod, and a second filter unit. The first filter unit is housed in the container, the connection rod inserts in the through hole and its lower end inserts into the container and connects with the first filter unit, and an upper of the connection rod extends out of the container. The second filter unit fits with the surround section so as to form an isolation space in the surround section, and the second filter unit includes an aperture and a leak-proof ring surrounding the second filter unit and matingly contacting with the container.

  • Publication number: 20170346243
    Abstract: A filtered connector is mounted on a casing and includes a connection port and a filter board. An electrode plate mounted on one end of the connection port and electrically isolated from the casing is securely mounted through a through hole of the casing. The filter board has a circuit board assembly, multiple grounding spring plates and multiple filtering capacitors. The circuit board assembly has a slot to be mounted through by the electrode plate. The grounding spring plates are mounted on a surface of the circuit board assembly and electrically contact the casing. The filtering capacitors are electrically connected between the electrode plate and the grounding spring plates. As the filter board is not mounted inside the connection port, only the filter board is to be mounted without replacing the connection port, thereby lowering users' expense in installation of the filter board.
