DESCRIPTION

The LH168M is a 384-output TFT-LCD source driver IC which can simultaneously display 262 144 colors in 64 gray scales.

FEATURES

• Number of LCD drive outputs : 384

• Built-in 6-bit digital input DAC

• Dot-inversion drive : Outputs the inverted gray scale voltages between LCD drive pins next to each other

• RSDSTM*(R_educed S_wing D_ifferential S_ignaling) input interface (Data and CK) : Possible to reduce E_lectro-M_agnetic I _nterference (EMI)

• Possible to display 262 144 colors in 64 gray scales with reference voltage input of 18 gray scales : This reference voltage input corresponds to ‹ correction and intermediate reference voltage input can be abbreviated

• Cascade connection
