LH168M
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
• Sampling sequence :
Output shift direction can be selected
XO1, YO1, ZO1/XO128, YO128, ZO128 or
ZO128, YO128, XO128/ZO1, YO1, XO1
• Shift clock frequency : 68 MHz (MAX.)
• Supply voltages
– VCC (for logic system) : +3.0 to +3.6 V
– VLS (for LCD drive system) : +12 V (MAX.)
• Package : 434-pin TCP (Tape Carrier Package)
* RSDS is a trademark of National Semiconductor Corporation.
SHARP recommends FPD87310 of National Semiconductor
Corporation as a timing controller for RSDSTM.
