Explanation


  • The driving waveforms (LUTs, lookup tables) have been pre-programmed in the driver IC. Developers just need to send image data and update command to complete the screen refresh.

  • If developers need special support to change the waveforms, extra LUTs can be sent externally.




  • Following our driving guide, developers can fully control the driving flow and stage from the MCU.

  • Developers need to send converted image data at each specific stage.

  • Taking longer time to design-in.

  • Longer initial, power-up and power-off periods. (500ms above)
