5. RELATIONSHIP BETWEEN INPUT DATA AND OUTPUT VOLTAGE VALUE

This product incorporates a 8-bit D/A converter whose odd output pins and even output pins output respectively

gray scale voltages of differing polarity with respect to the LCD’s counter electrode (common electrode) voltage. The

D/A converter consists of ladder resistors.

Be sure to maintain the voltage relationships as follows:

Figures 5

−2 shows

γ -corrected power supply voltage and ladder resistors ratio and Figures 5−3 shows the

relationship between the input data and the output voltage and the resistance values of the resistor strings.
