(9) Gray level control
This circuit implements the 4-gray level display.
(10) Data latch (1)
This circuit reads data for 208 pixels from RAM and latches it.
(11) Data latch (2)
This circuit latches data for 208 pixels in synchronization with the STB signal.
(12) Level shifter
The level shifter converts the operating voltage of the internal circuit(V
CC2
) into the voltage for the liquid crystal
driver circuit and row driver interface (V
CC1
).
(13) DEC
This is a decoder that decodes gray level display data to liquid crystal drive voltages V
0
, V
1
, or V
2
.
(14) Liquid crystal drive circuit
This circuit selects liquid crystal drive voltage V
0
, V
1
, or V
2
corresponding to gray level display data and the
display OFF signal (/DOFF), to generate a liquid crystal application voltage.
(15) Self-diagnosis circuit
If the operation timing of the master chip and that of the slave chip differ due to external noise, this circuit
automatically detects the difference and generates a refresh signal to all column drivers.
