  • Patent number: 11929016
    Abstract: A scan-type display apparatus includes an LED array and a scan driver. The LED array has a common anode configuration, and includes multiple scan lines, multiple data lines and multiple LEDs. The scan driver includes multiple scan driving circuits. Each scan driving circuit includes a voltage generator and a detector. The voltage generator has an output terminal that is connected to the scan line corresponding to the scan driving circuit, and is configured to output one of an input voltage and a clamp voltage at the output terminal of the voltage generator. The detector is connected to the output terminal of the voltage generator, and generates a detection signal that indicates whether any one of the LEDs connected to the scan line corresponding to the scan driving circuit is short circuited based on a voltage at the output terminal of the voltage generator and a detection timing signal.

  • Patent number: 11316298
    Abstract: Provided is a safety socket, including a first conductive seat, a second conductive seat, a first terminal, a first insulator, a second terminal, a second insulator, a first conductive sheet and a second conductive sheet. The first conductive seat includes a first elastic body. The first elastic body includes a first elastic connecting portion and two first elastic pieces. Both ends of the first elastic connecting portion are respectively integrally formed with the bottom ends of the first elastic pieces. The second conductive seat includes a second elastic body and a second socket terminal. The second elastic body includes a second elastic connecting portion and two second elastic pieces. Both ends of the second elastic connecting portion are respectively integrally formed with the bottom ends of the first elastic pieces. The elastic body can be reset by its own elastic force without a spring.

  • Patent number: 10985490
    Abstract: A safety socket is provided, comprising: a neutral-wire conductive base, a live-wire conductive base, an insulator, a neutral-wire wiring terminal, a live-wire wiring terminal, and a live-wire connection piece. The insulator is disposed between the neutral-wire conductive base and the live-wire conductive base. The contact of the neutral-wire wiring terminal is close to the contact of the first end of the neutral-wire conductive base. The live-wire wiring terminal is disposed between the live-wire conductive base and the insulator. The two contacts of the live-wire connection piece are respectively close to the contact of the second end of the live-wire conductive base and the contact of the live-wire wiring terminal. The invention can prevent electric shock when a conductive non-plug foreign body is inserted to provide high safety. The overall structure of the invention is simplified and easy to assemble, to achieve reducing manufacturing costs, and facilitating mass production.

  • Patent number: 10243296
    Abstract: A safety socket includes a main body, a first and second conductive seat, a first and second electric connection plates, a first and second insulated member and a first and second conductive plates. A first and second position block projects outwardly from first and second chambers of the main body. The first conductive seat includes a first clamp couch having two first clamp arms, one of which is formed with a first recess permitting extension of the first position block. The second conductive seat includes a second clamp couch having two second arms, one of which is formed with a second recess permitting extension of the second position block. The present safety socket has lesser components, easy to assemble and low in manufacturing cost, double safety measures. Addition of a switch device enhances the anti-shock effect and prevents occurrence of electrical discharge phenomenon and/or arc light phenomenon.
