LC7940KD / LC7941KDR
No.A0573-12/13
Segment Data Not Multiples of 4
Example.
If this timing data is sent, data elements (m, 229), (m, 230), (m+1, 229),(m+1, 230)… will not appear in the output
(O69 and O70 on chip 3). This is because the LC7940KD (or LC7941KDR) converts serial/parallel data in 4-bit units,
which also decrease power dissipation.
For data that is not a multiple of 4, like 230, the following scheme is used.
In this case, (m, 231) is output on O71 on chip 3, and (m, 232) on O72 on chip 3. However, these outputs are not
connected to the panel and are, therefore, invalid.
