Pixel Protocol Overview: TM1814

This pixel protocol was designed by Titan Micro Electronics in China. It is an improved design of its previous version, TM1804, offering RGBW capability as well as a faster PWM. The control circuit comes in a SOP8 package, allowing for more flexibility with LED choice.

TM1814 Advantages

  • Up to 32V, allowing for very long cable lengths
  • High PWM rate allows for filming these pixels with cameras up to 34fps
  • Presence of white LED allows for higher brightness and more color mixing options

TM1814 Disadvantages

  • Data-only restricts refresh rates to be limited by the speed of the protocol, which will generally be slow
  • Only 8 bits of data for each color makes dimming curves less smooth
  • No redundancy in data
