LH1687 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. 240-output TFT-LCD Source Driver IC PIN CONNECTIONS 264-PIN TCP TOP VIEW 1 OS1.
