Introduction

AI Translation

Huacaiwei's new generation digital LED is developed for high-definition image applications, featuring up to 16-bit grayscale data per channel and an internal 4-bit gamma correction, achieving a 20-bit display effect. The port refresh rate reaches up to 10kHz, making it highly suitable for large-display image rendering. The highly integrated digital LED requires no external electronic components, including capacitors. Dual-path input/output signals with automatic switching ensure reliability. Each RGB channel features 5-bit current gain functionality. The data protocol adopts a single-wire return-to-zero communication method. After power-on reset, the DIN port receives data transmitted from the controller. The first 48-bit data received is extracted by the first pixel and latched into its internal data latch; the remaining data is reshaped and amplified by the internal signal conditioning circuit, then forwarded via the DO port to the next cascaded pixel. With each pixel transmission, the signal is reduced by 48 bits. The pixels employ automatic signal reshaping and forwarding technology, so the number of cascaded pixels is not limited by signal transmission integrity — only by signal transmission speed requirements.

Features

AI Translation
  • Shared power supply for IC control circuit and LED point light source.
  • Control circuit and RGB die integrated in a 2121 package, forming a complete externally controlled pixel.
  • Built-in signal reshaping circuit; each pixel reshapes the waveform before output after receiving a signal, preventing waveform distortion accumulation along the line.
  • Built-in power-on reset and power-off reset circuits.
  • OUT R/G/B output grayscale levels: 65536.
  • Port scan frequency: 10kHz.
  • Current gain capability.
  • Serial cascading interface; data reception and decoding via a single signal line.
  • Ultra-compact 2.1×2.1×1mm (height) package.
  • RGB mixed white light color temperature: 6500K±500.
