Block Functions
1. Clock control unit
Generates the chip enable signals (EI00-2L, EIO0-2R) and controls internal timing signals.
2. Data inversion circuit
Uses the POL signal to perform polarity inversion (POL = 1) or non-inversion (POL = 0) processing on
input display data.
3. Latch address selector
Generates latch signals that sequentially latch the input display data.
4. Latch circuits (1)
384
×
6-bit latch circuits that sequentially latch 6-output
×
6-bit input display data.
5. Latch circuits (2)
Latch circuits that perform latching, in synchronization with CL4, of the 384
×
6-bit data latched by
latch circuits (1).
6. Latch circuits (3)
Latch circuits that perform latching, in synchronization with CL1, of the 384
×
6-bit data latched by
latch circuits (2), for the multiscan vertical enlargement function.
7. Decoders
The decoders generate 64 gradation voltages based on the liquid crystal drive voltages (V9 to V0), and
select the liquid crystal application voltages with decode signals from decoding of the 6-bit data.
8. Gradation voltage generation block
Performs resistance-division of the external input voltage, and generates 64 positive polarity gradations
and 64 low-voltage gradations.
9. Output amplifier circuits
The gradation voltage selected for each output is buffered in the operational amplifier and output.
