● Column driver circuit
Column driver circuit consists of 128 driver circuits. One of the four LCD driving level is selected by the
combination of M (internal signal) and the display data transferred from the latch circuit. Details of column
driver circuit are shown in Fig. 4.
● Row driver circuit
Row driver circuit consists of 64 drive circuits. One of the four LCD driving level is selected by the
combination of M (internal signal) and the data from the sift register. Details of row driver circuit are shown
in Fig. 5.
● DC−DC converter
The T6K04 has an on−chip DC−DC converter. The DC−DC converter generates ×2 (V
3) level and ×4 (V × 4) level. See Fig. 6
