LC4131C

Ordering number : EN*5953 CMOS IC LC4131C LCD Dot Matrix Common Driver for STN Displays Preliminary Overview The LC4131C is a common driver for large-scale dot matrix LCD panels. It includes a 120-bit bidirectional shift register and 4-level LCD driver circuits. The number of bits can be further increased by using the provided input and output pins to connect multiple LC4131Cs in cascade. The LC4131C and LC4104C 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: 2.7 to 5.5 V fcp max: 2.5 MHz Slim chip (output pads are concentrated on one of the longer sides) Bidirectional shift register The shift register can be split into two 60-bit registers. (Two screens drivable) DISPOFF function that locks the drive voltages output to the LCD at fixed levels. Display duty: 1/160 to 1/480 Appropriate for COG (chip on glass) mounting. (A gold bump structure is adopted in the pad areas.) Specifications The electrical characteristics values shown below are for devices encapsulated in the Sanyo standard PGA-208 package.
