5. RELATIONSHIP BETWEEN INPUT DATA AND OUTPUT VOLTAGE VALUE

This product incorporates a 6-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

between the LCD panel’s

resistance values are as shown on page 9. Among the 5-by-2

γ-corrected voltages, input gray scale voltages of the

same polarity with respect to the common voltage, for the respective five

Figures 2-1 and 2-2 show the relationship between the input data and the output data.

Table 1 shows the

resistance values of the resistor strings.

This driver IC is designed for single-sided mounting. Therefore, please do not use it for

γ-corrected power supply

use for double-sided mounting impairs the IC’s stable operation when the level of the

γ-corrected power supply

terminal is inverted thus causing display failures.
