DESCRIPTION
The LH1687 is a 240-output TFT-LCD source
driver IC used in such products as TV sets. The
LH1687 samples and holds three video signals of
R, G and B by sample and hold circuits
synchronized with the CK, and simultaneously
outputs the LCD drive voltage from all output pins.
FEATURES
Number of LCD drive outputs : 240
Output circuit form : Push pull output
Power save function : By setting the LCD drive
output in a high-impedance condition, the current
source of the LCD drive output circuit is cut off,
which makes low power operation possible
Sampling timing : Normal sampling operation and
3-point simultaneous sampling operation can be
selected
Video signal setting : Available for stripe pixel
array panels and delta pixel array panels using
mode setting circuit
Sampling clock frequency : 25 MHz (MAX.)
Cascade connection
Sampling sequence :
Output shift direction can be selected
