Hi Xiong:
Right now, I feel I am so close to success.
the screen seems split into two parts.
(the following picture is the Android Google’s loading animation)
I have modified the following sections:

I also checked the FPC and the LCD function works fine in LCD Bist mode. (Bist mode enter by modifying .dtsi DDI initial code)
according to your experience, is there are parts maybe I missing?
