Overview

The LC4104 is a segment driver LSI for large-scale dot matrix LCD displays. The LC4104 latches 160-bits of display data transferred from the controller over a 4- or 8-bit parallel interface and generates the LCD drive signals. In conjunction with the LC4102 common driver, the LC4104 forms a chip set that can drive large-screen LCD panels.

Features

• High-voltage CMOS (P-sub) process

• LCD drive voltage: 36 V

• Logic system power-supply voltage: 2.7 to 5.5 V

• Maximum fcp: 12 MHz (VDD = 5 V ±10), 10 MHz (VDD = 2.7 to 4.5 V)

• Slim chip (The output pads are located along one of the long sides.)

• Parallel input circuit can be switched between 4 and 8 bits.

• Output directionality switching

• DISPOFF function (Holds the LCD drive voltage at a fixed level.)

• Display duty ratios: 1/160 to 1/480

• Appropriate for COG (chip on glass) mounting. (A gold bump structure is adopted in the pad areas.)

• LC4104C: Chip product
