(10) Data latch (1)
This data latch reads and latches 160-pixel data from the RAM.
(11) Data latch (2)
This data latch synchronizes with the STB signal and latches 160-pixel data.
(12) Level shifter
The level shifter converts the voltage from the operating voltage of the internal circuit (3.3 V) to the voltage of the
liquid-crystal drive circuit and row driver interface (5.0 V).
(13) DEC
The DEC decodes the gray scale display data to make it compatible with the liquid-crystal drive voltages V0, V1,
and V2.
(14) Liquid-crystal drive circuit
This circuit selects one of the display OFF signal (/DOFF)-compatible liquid-crystal drive power supplies V0, V1,
or V2, and generates the liquid-crystal applied voltage.
(15) Self-diagnosis circuit
This circuit automatically detects any occurrence of an operation timing lag between the master chip and the
slave chip that has been caused by outside noise, and sends a refresh signal to all the column drivers.
