Module epd::lut

Waveform Look Up Table(LUT), which defines the display driving waveform settings.

LUT Table

phase0A phase0B phase1A phase1B phase2A phase2B phase3A phase3B phase4A phase4B

VS[n-XY], TP[n#], RP[n]

• The phase period defined as TP[n#] * T_FRAME, where TP[n#] range from 0 to 31 (5 bits)
  • TP[n#] = 0 indicates phase skipped.
• The Repeat counter defined as RP[n], which represents repeating TP[nA] and TP[nB].
  • RP[n] = 0 indicates run time =1, where RP[n] range from 0 to 63.
• Source Voltage Level: VS[n#-XY] is constant in each phase.
• VS[n-XY] indicates the voltage in phase n for transition from X to Y:
  • X, Y: H, L
  • 00 – VSS
  • 01 – VSH
  • 10 – VSL
  • 11 - ? HiZ
