When designing a RED LED 114X90 Dot by applying LP5891-Q1,
Should I configure the ICs as 3X2 and apply 38 DATAs and 15 SCANs to each IC?

    Hi Ahn Young Taek,

    1. how much pixel pitch and pixel current do you need for you application? since I notice that you use 39k as the Riref which is really big for auto application.
    2. the SOUT of device N should connects with SIN of device N+1.
    3. the un-used lines must belong to the last device. and below block provide one solution for your application.

    could you share same information about your case and we can help to review the schematic? you can send to my mail if you don't want to public it.
