3)End sub instruction mode
Although the partial display instruction changes duty cycle ratio automatically and display area, LCD driving
voltage, Bias and others are not changed. Therefore, the instruction of LCD driving voltage “OFF” (D=0) must
be set before partial display operation, and the other instructions such as the n-line inverse drive set, EVR
register set, bias select and voltage booster select should be set for optimum display-contrast. The “End of sub
instruction mode” is required before these instructions in order to prevent momentary flickering.
