35.19.1 When Division Resistors are Connected Externally
35.19.2 Voltage Multiplier
The reference value of R1 to R4 is 200 k , and the reference value of C1 to C4 is 0.22 F. These optimal
values depend on the LCD panel, the number of segment and common pins, and the frame frequency in use.
Adjust the values as required (refer to Figure 32.4).
The reference value of CL is 0.22 F, and the reference value of C1 to C4 is 0.22 F. These optimal values
depend on the LCD panel, the number of segment and common pins, and the frame frequency in use. Adjust the
values as required (refer to Figure 32.5).
