I am replacing an LCD screen with an OLED screen and the supply voltage is supposed to be 5 volts. 4.8 min to 5.3 max. Is it possible to change the voltage for pin 14 from 6 to 5 volts? There is a stable 9 volts feeding this circuit. Is it possible to make the changes in the red highlighted area? And could you provide an explanation of what is happening in that section of the diagram? Thanks in advance for any help
