The Fitipower JD9161Z LCD driver IC is very similar to the Jadard JD9365DA-H3, it just uses different initialization sequences. The two initialization sequences for the panel have been extracted from Android original firmware for the Xiaomi Smart Clock. Variant -ctc uses a CTC LCD panel and has been tested on device. Variant -boe uses a BOE LCD panel and has not been tested.
