Command
Aug 2005
The next command determines multiplex ratio N
from 16MUX-80MUX, POR=4FH(80MUX)
A[0] = 0, Disable DC-DC converter
A[0] = 1, Enable DC-DC converter (POR)
A[1] = 0, Disable internal VCOMH
A[1] = 1, Enable internal VCOMH (POR)
AEH = Display Off (Sleep mode) (POR)
AFH = Display On
Second command A[5:0] sets the VCOMH voltage
level 000000-011111
A[5:0] = 1xxxxx = 1.0*VREF
A[5:0] = 010001(POR)
Second command A[7:0] sets the precharge
voltage level 00000000-00011111
A[7:0] = 1xxxxxxx connects to VCOMH
A[7:0] = 001xxxxx equals 1.0*VREF
A[7:0] = 00011000(POR)
A[3:0] = P1, phase 1 period of 1-15 DCLK clocks,
POR = 3DLKS = 3H
A[7:4] = P2, phase 2 period of 1-15 DCLK clocks,
POR = 5DLKS = 5H
The next command sets the number of DCLKs, K,
per row between 2-158DLKS, POR = 37DLKS =
25H
The K value should be set as
K = P1+P2+GS15 pulse width (POR: 3+5+29DLKS)
The lower nibble of the next command sets the
divide ratio of the display clocks:
Divide ratio = 1-16, POR = 2
The higher nibble of the next command sets the
Oscillator Frequency. Oscillator Frequency
increases with the value of
A[7:4] and vice versa. POR=0
