3 B Product Introduction
Traditional full-color series products need to drive lamp beads. The most important thing is that they require a large number of capacitors and resistors, and then use The circuit board combines electronic components one by one, with countless circuit vias, copper sinking, and countless soldering pads. . . Although it is only a small finished product in the hands of the customer, it has gone through countless processes to complete. It is inevitable that there will sometimes be some small flaws in the middle, which is a problem of failure rate. The emergence of built-in lamp beads completely solves this traditional problem. It has dramatically shortened the distance between the driver and the lamp beads, easily eliminating the headaches and inevitable problems that the majority of boss electronic engineers will have
.3 B Product Features
< . Intelligent Reflection Connection protection, reverse connection of power supply will not damage it.
.
The control circuit and the point light source share a common power supply.
. The control circuit and chip are integrated into a packaged component to form a complete externally controlled pixel.
. Built-in signal shaping circuit, any pixel point receives the signal and then outputs the waveform through waveform shaping, ensuring that line waveform distortion will not accumulate.
. Built-in power-on reset and power-off reset circuit.
. The three primary colors of each pixel can achieve
level brightness display, complete
true color display of
colors, and the scanning frequency is not lower than
.
. The serial cascade interface can complete the reception and decoding of data through a signal line.
. When the transmission distance between any two points does not exceed
meters, there is no need to add any circuits.
. When the refresh rate is 3 frames/second, the number of cascades is not less than point.
. The data sending speed can reach

.
. The color of the light is highly consistent and cost-effective.

3 B product composition
.. .3
It is an intelligent external control
light source that integrates control circuit and light-emitting circuit. Its appearance is the same as a
lamp bead, and each component is a pixel.
The pixel contains an intelligent digital interface data latch signal shaping amplification drive circuit, a high-precision internal oscillator and a high-voltage programmable constant current control part, which effectively ensures that the color of the pixel light is highly consistent.
.. .3 The data protocol adopts the single-line return-to-zero code communication method. After the pixel is powered on and reset, the
terminal accepts the data transmitted from the controller. The
data sent first
After being extracted by the first pixel, it is sent to the data latch inside the pixel. The remaining data is reshaped and amplified by the internal shaping processing circuit and then forwarded and output to the next cascade through the
port. Every time a pixel is transmitted, the signal decreases
.
The pixel adopts automatic shaping and forwarding technology, so that the number of cascades of the pixel is not limited by the signal transmission, but is only limited by the signal transmission speed requirements.
.. .3
It has the advantages of low voltage drive, environmental protection and energy saving, high brightness, large scattering angle, good consistency, ultra-low power, ultra-long life, etc. Integrating the control circuit on it makes the circuit simpler, smaller in size and easier to install.
