Microprocessor Interface and LCD Blanking
1) When the microprocessor is reset, the port pin will be configured as an input and so the STR line would float.
The pull-up resistor will ensure that the LCD is blank while the system reset line is active and after until the
port pin is set up by software.
Writing Data to the Display RAM while keeping the LCD Blank
V6118 with External Resistor Divider Bias Generation
Example set values:
R = 3.3 – 10 kΩ
C = 2.2 – 47 nF
Rx is given by the formula:
Rx = 4R ((VDISP/VLCD)-1) = 10 – 30 kΩ
