Description

WS2813 is an upgraded version of WS2812.

WS2813 is an intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components. Its 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,

which achieves highly consistent color effect.

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. Every pixel adopts auto-reshaping transmit technology, making the pixel cascade numbers are not limited to the signal transmission, only relate to the speed of signal transmission. 

The BIN receives the data signal, and then compare the data with the DIN side after phagocytosis of 24bit data, if DIN do NOT receive the signal, then switching to BIN for receiving the input signal, which ensure that any the IC's damage does not affect the signal cascade transmission and make the BIN in state of receiving signal until restart after power-off. 

Refresh Frequency updates to 2KHz, Low Frame Frequency and no Flicker appear in HD Video Camera.

250us or more of reset time, it won’t cause wrong reset while interruption, it supports the lower frequency and inexpensive MCU.

There’re in a choice of 18mA or 5mA current version, and also in a choice of high brightness or cost-effective version. That is to say, WS2813 is provided with four versions.

Features and Benefits

  •  The control circuit and the LED share the only power source.

  •  The control circuit and RGB chip are integrated in a 5050 components, to form an external control pixel.

  •  Using the built-in signal reshaping circuit to achieve the signal waveform shaping, and no distortion of waveform of

  • signal takes place.

  •  Built-in power-on reset and brown-out reset circuits.

  •  The gray levels of each pixel are of 256 levels, which achieves “256*256*256=16777216” full-color display, and

  • the refresh frequency reaches to 2KHz/s.

  •  Serial cascade interface, data receiving and decoding depend on just one signal line.

  •  Dual-signal wires version, signal break-point continuous transmission.

  •  Any two point the distance more than 3m transmission signal without any increase circuit.

  •  When the refresh rate is 30fps, cascade numbers are far more than 1024 points.

  •  Data transmitting at speeds of up to 800Kbps.

  •  Good color consistency reliability, high cost-effective.

描述

WS2813是WS2812的升級版本。

WS2813是智能控制LED光源,控制電路和RGB芯片集成在5050組件的封裝中。其內部包括智能數字端口數據鎖存和信號整形放大驅動電路。還包括精密內部振盪器和12V電壓可編程恆流控制部件,

實現了高度一致的色彩效果。

數據傳輸協議使用單個NZR通信模式。像素上電複位後,DIN端口從控制器接收數據,第一個像素收集初始的24bit數據,然後發送到內部數據鎖存器,其他數據通過內部信號重新整形放大電路發送到下一級聯像素通過DO端口。傳輸後每個像素,信號減少24bit。每個像素採用自整形傳輸技術,使得像素級聯數不限於信號傳輸,僅與信號傳輸速度有關。

BIN接收數據信號,然後在吞噬24位數據後將數據與DIN側進行比較,如果DIN未接收到信號,則切換到BIN以接收輸入信號,確保任何IC的損壞不會影響信號級聯傳輸,使BIN處於接收信號狀態,直到斷電後重新啟動。

刷新頻率更新為2KHz,低幀頻和無閃爍出現在高清攝像機中。

250us以上的複位時間,中斷時不會造成複位錯誤,支持低頻和廉價的MCU。

可選擇18mA或5mA當前版本,還可選擇高亮度或高性價比的版本。也就是說,WS2813有四個版本。

特點和優點

  • 控制電路和LED共享唯一的電源。

  • 控制電路和RGB芯片集成在5050組件中,形成外部控制像素。

  • 採用內置信號整形電路實現信號波形整形,無畸變波形

  • 信號發生。

  • 內置上電複位和欠壓復位電路。

  • 每個像素的灰度級別為256級,實現“256 * 256 * 256 = 16777216”全色顯示,

  • 刷新頻率達到2KHz / s。

  • 串行級聯接口,數據接收和解碼僅取決於一條信號線。

  • 雙信號線版本,信號斷點連續傳輸。

  • 任何兩點距離超過3米的傳輸信號無任何增加電路。

  • 當刷新率為30fps時,級聯數遠遠超過1024點。

  • 數據傳輸速度高達800Kbps。

  • 色彩一致性好,性價比高。
