80 x 128 pixels matrix LCD driver

Instead of using the VLCD offset pads (VOS[4:0]) the VLCD can be adjusted with the module

maker calibration setting MMVOPCAL[4:0]; see Section 18.

(4)

Where:

• TCUT is a reference temperature; see Section 12.11

• a is a ﬁxed constant value; see Table 27

• b is a ﬁxed constant value; see Table 27

• VOP[7:0] is the result of the conversion table

• VOS[4:0]/MMVOPCAL[4:0] is the value of the offset VLCD pads or the value stored in

the OTP cells
