Pixel Protocol Overview: QED3001

This pixel protocol was designed by QED MicroElectronics Inc. in China. The control circuit can come in a SOP8/SOP10/SOP14 package, depending on which functions are being used, allowing for more flexibility with LED choice.

PixLite Support

Are you looking for QED3001 pixel drivers that work with Art-Net or sACN? All PixLite Mk1, Mk2, and Mk3 products support QED3001 as an available Pixel IC type, so get in touch with us to find out how the lighting specialists at Advatek can support you in your pixel lighting project.

Note: When configuring your PixLite device, select 'TLS3001' as your Pixel Type. This is the equivalent protocol that will allow you to use QED3001 pixels.

QED3001 Advantages

  • High PWM rate allows for filming these pixels with cameras up to 34fps
  • Up to 32V, allowing for very long cable lengths
  • Option for redundant data line reduces chance of entire strip failure
  • 12 bits of data for each color makes dimming curves more smooth

QED3001 Disadvantages

  • Data-only restricts refresh rates to be limited by the speed of the protocol, which will generally be slow

Operational Behavior

On start-up, only the first QED3001 pixel in a chain will illuminate for a second, while the pixels initialise themselves. When initialisation has completed, all pixels will proceed to respond to their incoming data.
