7 / 21 page Data Sheet S10565EJ2V0DS 5 µ PD16641 4. RELATION BETWEEN INPUT DATA AND OUTPUT VOLTAGE VALUE The 11 major points on the γ-characteristic curve of the LCD panel are arbitrarily set by external power supplies V0 through V10. If the display data is 00H or 3FH, gray scale voltage V0 or V10 is output. If the display data is in the range 01H to 3EH, the high-order 3 bits select an external powers pair Vn+1, Vn. The low-order 3 bits evenly divide the range of Vn+1, Vn into eight segments by means of D/A conversion (however, the ranges from V9-V8 and from V2-V1 are divided into seven segments) to output a 64-grayscale voltage.
