boost mode, where VDD is 3.3V and VOUT is 16.5V. VOUT is the operating voltage of the
operational amplifier delivering the operating voltage, V0, for the LCD panel.
The LCD operating voltage, V0, is set with two resistors, R
when the resistors are external. INTRS is driven High when the resistors are internal. For
the XlvdsPro_PwrIo board, internal resistors are selected.
The LCD operating voltage (V0) and the Electronic Volume Voltage (V
in units of V with these formulae:
In
The values of the reference voltage parameter, , and the ratio R
bit settings in the LCD controller’s instruction registers. Thus, it is possible to change
physical operating parameters of the LCD through register bit settings, controlling the
operating voltage, and the electronic volume level.
