INTERFACE SIGNAL DESCRIPTION
DOT CLOCK - This signal enters the SERIAL DATA on each
low to high transition. A total of 128 DOT CLOCK transitions
must be present for each line of column/anode data.
SERIAL DATA - This signal presents the pixel data in positive
logic format. A logic one represents a lit pixel and a logic
zero represents an extinguished pixel. Data is entered from
right to left. The first pixel data entered will represent the left
most pixel in the row.
COLUMN LATCH - This signal latches the pixel data into
the driver outputs. When the COLUMN LATCH signal goes
to logic one the data entered previously will fall through to
the driver outputs. When the signal returns to a logic zero
the data is latched and the shift register is now ready to accept
the next row of data. Must be held low while entering new
SERIAL DATA.
DISPLAY ENABLE - This signal enables the output drivers.
Using a duty cycle control, this signal may also be used for
intensity control. The DISPLAY ENABLE must be at logic
zero before the COLUMN LATCH signal transitions. To avoid
display blurring, the ROW CLOCK signal should also
transition while DISPLAY ENABLE is a logic zero.
ROW DATA - This signal is the first line marker for the scan.
This input should be held high to correspond to the first row
of pixel data.
ROW CLOCK - This signal clocks ROW DATA on the falling
edge. The ROW CLOCK signal is repetitive and must be
present for proper scanning of the display module.
The LED-128G032 has an unique input protection circuit that
assures the column drivers stay blanked on power up. The
protection circuit unblanks the column drivers when the ROW
CLOCK signal begins (i.e the display begins scanning.)
