LH1687 240-output TFT-LCD Source Driver IC

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. 240-output TFT-LCD Source Driver IC PIN CONNECTIONS 264-PIN TCP TOP VIEW 1 OS1 FEAT.

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 direct.
