  • Patent number: 10170076
    Abstract: A method for sending commands to display devices connected in series includes sending a command to the first display device of N display devices connected in series. The command has a header and each of the N display devices has a same preset identification code. The first display device of N display devices receives the command and determines whether the header is corresponding to the preset identification code. When the header of the command is corresponding to the preset identification code, the first display device executes the command. When header of the command is different from the preset identification code, the first display device generates a modified command by adding an adjustment to the header of the command and sends the modified command to the next display device.

  • Patent number: 9445470
    Abstract: An LED control circuit comprises a driver, a counter, and a controller and is configured to control a plurality of light-emitting units, each of which comprises at least one LED and a switch. The driver receives an alternating-current signal to output a driving signal whereby the light-emitting units are enabled. The counter begins a count from a start number when a voltage value of the driving signal equals a base value. When the count reaches a predetermined number, the controller controls the switch of at least one of the light-emitting units, causing the LED of the light-emitting unit to receive the driving signal. When the LED of the light-emitting unit receives the driving signal, the controller detects whether the light-emitting unit is enabled and adjusts the predetermined number accordingly.
