What is the HD105 Pixel LED? 

HD105-RGBW is an intelligent externally controlled LED light source integrating control circuit and light emitting circuit. Its appearance is the same as a 5050 LED bead, each component is a pixel. The pixel contains intelligent digital interface data latch signal shaping and amplification driving circuit, anti-reverse connection circuit, high-precision internal oscillator and high-precision constant-current control module, effectively ensure that the color of the pixel light is highly consistent . Dual signal transmission is achieved so that the overall color display is not affected in case of damage to a single
pixel point. The data protocol adopts the communication mode of single-wire zeroing code. After power-on reset, the pixel point accepts the data transmitted from the controller at the DIN1 end, and the 32bit data firstly sent over is extracted by the first pixel point and then sent to the data latch inside the pixel point, and then the remaining data is amplified by the internal shaping processing circuit and then begins to be forwarded and outputted to the next cascade of pixel points through the DO port, and the signal is reduced by 32bit after the transmission of one pixel point each. After the transmission of one pixel, the signal is reduced by 32bit.The pixel point adopts the automatic shaping and forwarding technology, which makes the number of cascade of the pixel point is not limited by the signal transmission, but only limited by the signal transmission speed requirement.

With a port scanning frequency of up to 16KHz, there is no flicker even when captured by HD cameras, making it ideal for high-speed mobile products.With a transmission speed up to 30Mbps which ensures a smoother working and better lighting effect. 

What's the difference between HD105 RGBW and WS2815 RGBW LED? 

The main difference from HD105 RGBW Pixel LED to WS2815 RGBW Pixel LED is on brightness, refresh rate and transmission speed, following is the details comparison,
