LC
is the peak value of the optimum drive voltage for LCD. (it varies depending on the LCD.)
R is a resistance of 1 k
to 10 k
. Select the resistance value according to the load.
A larger value for R reduces the power dissipation, but causes drive waveform distortions.
Select a largish value for a variable resistor so as to satisfy the equation above.
2. When using internal bias
A heavy LCD load may cause distortions in the common waveform. In this case, insert a capacitor for V
