FUNCTIONAL OPERATIONS OF EACH BLOCK
BLOCK
Used as a bi-directional shift register which performs the shifting operation by CK and
selects bits for data sampling.
Data Latch
Used to temporary latch the input data which is sent to the sampling memory.
Sampling Memory
Used to sample the data to be entered by time sharing.
Hold Memory
Used for temporary latch processing of data in the sampling memory by LS input.
Used to shift the data in the hold memory to the power supply level of the analog circuit
unit and sends the shifted data to DA converter.
Reference Voltage
Generation Circuit
Used to generate an analog signal according to the display data and sends the signal to
the output circuit.
Used as a voltage follower, configured with an operational amplifier and an output buffer,
which outputs analog signals of 64 gray scales to LCD drive output pin.
