Abstract: The subject application relates to a server, terminal and non-transitory computer-readable medium. The server for handling streaming data for a live streaming, comprising one or a plurality of processors, wherein the one or plurality of processors execute a machine-readable instruction to perform: recording the streaming data for the live streaming; storing the streaming data as archive contents with first identifier; receiving interaction information during the live streaming; storing the interaction information as contexts with second identifier, transmitting the archive contents with first identifier to a first user terminal; and transmitting the contexts to the first user terminal according to the first identifier and the second identifier. According to the subject application, the archive contents may be more immersive and the user experience may be enhanced.

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.

Abstract: The invention discloses an LED lamp and an LED lamp string having a load connected to both ends of an LED, and the lamp acts like a non-polarized lamp to an alternate current and maintains to be half-wave lit. No consideration of anode and cathode is needed for connecting the LEDs of the lamp string in series on an electric wire. Even when an LED is damaged to produce an open circuit, electric current still can pass through the load connected to the damaged LED to light up the rest LEDs. Since the LED will not be damaged easily while blinking, the LED has a long life. It is not necessary to consider the polarity of the LED for its installation, and thus making the installation and replacement more convenient. The invention comes with a voltage divider or choke that can resist voltage or current surges.
