Lamp Test
When the lamp test (LT) is activated, all dots on the display are illuminated at 1⁄ 7 brightness. The lamp
test function is independent of write (WR) and the settings of the blanking inputs (BL0, BL1).
This convenient test gives a visual indication that all dots are functioning properly. Lamp test also may
be used as a cursor function or pointer which does not destroy previously displayed characters.
Dimming and Blanking the Display
Loading Data
Loading data into the display is straightforward. Chip enable (CE) should be present and stable during a
write pulse (WR). Parallel data information should be stable for the minimum time (T
TDH after write has gone high. No synchronization is necessary and each character will continue to be
displayed until it is replaced with another. Multiple displays may be stacked together with only an
additional decoder IC for chip enable decoding.
