• Manufacturer: Crystalfontz America, Inc.,

Partial Display Mode
The SSD2119 enables to selectively drive two screens at arbitrary positions with the screen-driving position registers
(R48h to R4Bh). Only the lines required to display two screens at arbitrary positions are selectively driven to reduce the
power consumption.
The first screen driving position registers (R48 and R49) specifies the start line (SS18-10) and the end line (SE18-10) for
displaying the first screen. The second screen driving position register (R4A) specifies the start line (SS28-20) and the
end line (SE28-20) for displaying the second screen. The second screen control is effective when the SPT bit is set to 1.
The total number of lines driven for displaying the first and second screens must be less than the number of lines to drive
the LCD.
Condition:
SS1[8:0] ≤ SE1[8:0] ≤ EFH
