xt1505 mini is a smart led control circuit and light emitting circuit in one controlled ledsource, which has the shape of a 5050 led chip. each lighting element is apixel, and the intensities of the pixels are contained within the intelligentdigital interface input. the output is driven by patented pwm technology, whicheffectively guarantees high consistency of the color of the pixels. the controlcircuit consists of a signal shaping amplification circuit, a built-in constantcurrent circuit, and a high precision rc oscillator.
the data protocol being used isunipolar nrz communication mode. the 24-bit data is transmitted from thecontroller to din of the first element, and if it is accepted it is extractedpixel to pixel. after an internal data latch, the remaining data is passedthrough the internal amplification circuit and sent out on the do port to theremaining pixels. the pixel is reset after the end of din. using automaticshaping forwarding technology makes the number of cascaded pixels withoutsignal transmission only limited by signal transmission speed.
the led has a low driving voltage (which allows forenvironmental protection and energy saving), high brightness, scattering angle,good consistency, low power, and long life. the control circuit is integratedin the led above.
