While user sent this command, driver will refresh display (data/VCOM) base on SRAM data and LUT.
Only the area (X,Y, W, L) would update, the others pixel output would follow VCOM LUT After display refresh command, BUSY_N
signal will become “0”.
Note: X and W should be the multiple of 8.
DFV_EN: data follow VCOM function on display area.
DFV_EN=1: Only effective in B/W mode, if pixel from “New data” SRAM equal to “Old data” SRAM on display area, this pixel output
would follow VCOM LUT.
DFV_EN=0: Data doesn’t follow VCOM LUT.
This command only active when BUSY_N = “1”.
(16) VCOM LUT (LUTC) (R20H)
This command builds Look-up Table for VCOM
(17) W2W LUT (LUTWW) (R21H)
This command builds Look-up Table for White-to-White.
(18) B2W LUT (LUTBW/LUTR) (R22H)
This command builds Look-up Table for Black-to-White.
(19) W2B LUT (LUTWB/LUTW) (R23H)
This command builds Look-up Table for White - to- Black.
(20) B2B LUT (LUTBB / LUTB) (R24H)
This command builds Look-up Table for Black - to- Black.
