Description
PTG [1:0]: Set the scan mode in non-display area.
PTG1 PTG0 Gate outputs in non-display area Source outputs in non-display area VCOM output
0 0 Normal scan Set with the PT [2:0] bits VCOMH/VCOML
0 1 Setting prohibited --- ---
1 0 Interval scan Set with the PT [2:0] bits
1 1 Setting prohibited --- ---
PT [1:0]: Determine source/VCOM output in a non-display area in the partial display mode.

SS: Select the shift direction of outputs from the source driver.
SS Source Output Scan Direction
0 S1  S720
1 S720  S1
In addition to the shift direction, the settings for both SS and BGR bits are required to change the assignment of R, G,
and B dots to the source driver pins.
To assign R, G, B dots to the source driver pins from S1 to S720, set SS = 0.
To assign R, G, B dots to the source driver pins from S720 to S1, set SS = 1.
REV: Select whether the liquid crystal type is normally white type or normally black type.
REV Liquid crystal type
0 Normally black
1 Normally white
ISC [3:0]: Specify the scan cycle interval of gate driver in non-display area when PTG [1:0] =”10” to select interval scan.
Then scan cycle is set as odd number from 0~29 frame periods. The polarity is inverted every scan cycle.
