Led driver with dual encoding formats for data signal
A recently granted patent (Publication Number: US11974371B2) discloses a novel light-emitting diode (LED) driver system that includes a decoding circuit and an encoding circuit. The decoding circuit receives a data signal, decodes it to generate display data for driving LEDs, and recovers a clock signal. The encoding circuit then encodes the decoded display data using the recovered clock signal to generate an encoded data signal. Notably, the data signal is encoded in one format, while the encoded data signal is in a different format, such as Manchester encoding or four-level pulse amplitude modulation (PAM4). The patent further details the intricate workings of the decoding and encoding circuits, including delay circuits, sampling circuits, logic operation circuits, and data conversion circuits, to ensure efficient LED driving and display.
Moreover, the patent extends the LED driver system to a multi-stage LED driving device, where each stage comprises the innovative LED driver described in the claims. The interconnected stages receive and process data signals sequentially, with each stage building upon the output of the previous one. This modular approach allows for scalable LED driving solutions with enhanced functionality and performance. The patent's detailed description of the LED driver's components, operations, and interactions provides valuable insights into the technical advancements in LED display technology. By leveraging different encoding formats and sophisticated circuitry, the LED driver system promises improved efficiency, reliability, and flexibility in driving LEDs for various applications.
