Single-Wire LED Data Transmission Circuit

The patent combines the clock signal and data signal into a single data line by encoding timing information within the data pulses themselves. The receiver detects pulse transitions to generate clock signals locally, eliminating the need for separate clock conductors while maintaining synchronization and decoding accuracy.

The data line serves multiple functions: it transmits both data information and timing/clock information simultaneously. The same conductor that carries data pulses also enables the receiver to generate synchronized clock signals through pulse transition detection, reducing the overall number of required conductors.

By merging clock and data transmission into a single line, the patent reduces the total number of conductors required for large LED displays. This consolidation decreases wiring complexity and potential failure points while maintaining the capacity to control numerous LEDs through efficient pulse encoding and sequential scanning.

The patent divides the display into segments that can be controlled sequentially through the single data line. Data is transmitted in pulses that can be buffered and processed in stages, allowing large displays to be controlled reliably through systematic segmentation rather than requiring simultaneous control of all LEDs.

The patent merges timing signal transmission with data transmission by using the same data line for both purposes. The receiver generates clock signals by detecting pulse transitions in the data stream, eliminating the need for separate timing conductors while maintaining precise synchronization for accurate decoding.

The receiver generates its own clock signals by detecting pulse transitions in the incoming data stream. This self-synchronization mechanism eliminates the need for external clock conductors, as the system uses the data pulses themselves to generate the timing references needed for proper decoding.
