LC4101C
LCD Dot Matrix Segment Driver
for STN Displays
Overview
The LC4101C is a segment driver for large-scale dot
matrix LCD panels. It latches 240 bits of display data sent
from the controller over a 4-bit or 8-bit parallel connection
and generates the LCD drive signals. The LC4100C and
LC4101C form a large-screen LCD panel driver chip set.
Features
• Fabricated in a CMOS (P-sub) high-voltage process.
• LCD drive voltage: 36 V
• Logic system power-supply voltage: 3.0 to 5.5 V
• f_cp max: 12 MHz (V_DD = 5 V ±10 %), 6.5 MHz (V_DD
= 3 to 4.5 V)
• 240 outputs
• Parallel input switchable between 4 and 8 bits
• DISPOFF function that locks the drive voltages output
to the LCD at fixed levels.
• Display duty: 1/160 to 1/480
