  • Display device, method for transmitting data packet, and LED system
    Patent number: 9812059
    Abstract: A display device is provided. The display device includes a transmitter, a plurality of first receivers, a plurality of second receiver modules, and a plurality of LED driver groups. The transmitter transmits at least one of a configuration data packet and an image data packet. Each of the configuration and image data packets includes a set of field information. At least one first receiver is coupled to the transmitter. Each of the plurality of second receiver modules is coupled to at least one of first receivers. Each of the plurality of second receiver modules includes a plurality of second receivers. Each of the second receivers reads the set of field information so as to determine whether the set of field information is designated thereto. Each of the plurality of LED driver groups is coupled to the at least one of the second receivers. Each of the plurality of LED driver groups includes a plurality of LED drivers.
