The working principle and application of 5050 fantasy built -in IC lamp beads

Data protocol adopts a single -polarity to zero -code communication method. After the pixels are power -on and reset, the DIN terminal accepts data transmitted from the controller. The first 24bit data sent by the controller is extracted To the internal data locks of the pixel point, the remaining data will be reposted and output to the next -level pixel dot through the DO port through the DO port, and the signal is reduced by 24bit each passing through a pixel point transmission. The pixel point adopts automatic plastic transmission technology, so that the number of levels of the pixel point is not limited by the signal transmission, and only the limited signal transmission speed requirement. LED has the advantages of low -voltage driver, environmental protection and energy saving, high brightness, large scattered angle, good consistency, ultra -low power, ultra -long life and other advantages. Integrated the control circuit on LED, the circuit becomes simpler, the volume is small, and the installation is easier.

dLED Internal Integrated high -quality external control single -line serial -level linked IC; ? control circuit and chip integrated in SMD5050 components, forming a complete external control pixel point, the color temperature effect is uniform and consistent.路 Built -in data plastic surgery circuit, any pixel point receives the signal and outputs through waveform plastic surgery to ensure that the line waveform distortion of the line will not be accumulated.和 Built -in -on -power reset and power reduction and reset circuit, the power -on does not light up; United.技術(shù) Plastic transmission and reinforcement technology. The transmission distance between two points can exceed 10m.? The data transmission frequency can reach 800kbps. When the refresh rate is 30 frames/second, the number of couplets is not less than 1024 points.
