  • Patent number: 11012419
    Abstract: A system including a network communication device, a storage device, and a controller is provided. The storage device stores first mappings between IP addresses and devices, and second mappings between software and devices. The controller obtains a connection log from the proxy server or the firewall device via the network communication device, uses the first mappings and the second mappings to analyze the connection log to determine one or more different connections between connections of devices on which first software is installed and connections of devices on which the first software is not installed, determines whether the first software functions normally on a first device blocking the different connections, and adds destination addresses of the different connections into a blocking list in response to the first software functioning normally on the first device, such that the proxy server or the firewall device blocks all connections towards the destination addresses.

  • Patent number: 10818644
    Abstract: A display device includes multiple packages, each including a substrate, multiple pixel members, and an encapsulant. Each of the pixel members includes a first light emitting diode (LED) chip, a second LED chip, and a third LED chip. The LED chips of one of the two adjacent pixel members are arranged along a first direction, and the LED chips of the other one of the two adjacent pixel members are arranged along a second direction orthogonal to the first direction. Each of the packages has a first spacing between the first LED chips of the two adjacent pixel members. The first LED chip of each pixel member in each package is spaced apart from a nearest one of the first LED chips of the nearest package by a second spacing equal to the first spacing.

  • Patent number: 9685428
    Abstract: A light-emitting array module includes a circuit substrate, a light-emitting unit, and an encapsulation body. The light-emitting unit includes a plurality of light-emitting groups arranged in matrix on the circuit substrate. The encapsulation body disposed on the circuit substrate for encapsulating the light-emitting groups. The encapsulation body includes a plurality of encapsulation portions and a plurality of thin connection portions. Therefore, light beams generated by the light-emitting group is transformed into an obvious single point light source without halation due to the design of “each thin connection portion connected between the two adjacent encapsulation portions to separate the two adjacent encapsulation portions from each other by a predetermined distance”, so that the color resolution of the light-emitting array module is increased. In addition, the present disclosure further provides a display device including the light-emitting array module.
