APA104 White 5050 LED chip-SHENZHEN LED COLOR Co.,LTD

APA104 White 5050 LED chip

Features and Benefits

l.Intelligent reverse connect protection, the power supply reverse

connection does not damage the IC.2 The control circuit and the

LED share the only power source.

2.Control circuit and RGB chip are integrated in a package of 5050

components, form a complete control of pixel point.

3. Built-in signal reshaping circuit, after wave reshaping to the next

driver, ensure wave-form distortion not accumulate.

4. Built-in electric reset circuit and power lost reset circuit.

5. Each pixel of the white ,can achieve 256 brightness

display,, and scan frequency not less than 400Hz/s.

6. Cascading port transmission signal by single line.

7.Any two point the distance more than 5m transmission signal

without any increase circuit.

8 When the refresh rate is 30fps, cascade number are not less than

1024 points.

9. Send data at speeds of 800Kbps.

10.l The color of the light were highly consistent, cost-effective..

Applications

11. Full-color module, Full color soft lights a lamp strip.

12. LED decorative lighting, Indoor/outdoor LED video irregular screen.

General description

APA104 is a intelligent control LED light source that the control circuit and white chip are integrated in a package of
5050 components. It internal include intelligent digital port data latch and signal reshaping amplification drive circuit.
Also include a precision internal oscillator and a 12V voltage programmable constant current control part, effectively
ensuring the pixel point light color height consistent. The data transfer protocol use single NZR communication mode.
After the pixel power on reset, the DIN port receive data from controller, the first pixel collect initial 24bit data then
sent to the internal data latch, the other data which reshaping by the internal signal reshaping amplification circuit sent
to the next cascade pixel through the DO port. After transmission for each pixel，the signal to reduce 24bit. pixel adopt
auto resha-ping transmit technology, making the pixel cascade number is not limited the signal transmission, only
depend on the speed of signal transmission.LED with low driving voltage, environmental protection and energy saving,
high brightness, scattering angle is large, good consistency, low power, long life and other advantages. The control chip
integrated in LED above becoming more simple circuit, small volume, convenient installation.
