Description
The LC79400D is a large-scale dot matrix LCD segment driver integrated circuit that operates as a buffer/driver/transceiver. It processes display data transferred from a controller by using a 4-bit parallel format. This data is then processed through an 80-bit latching mechanism which produces an LCD drive signal. This component can be used in conjunction with common drivers such as LC7943D (QIP80D), LC79430D (QIP100D), and LC79431D (QIP100D) to drive a wide screen LCD panel.
Specifications and Features
- On-chip LCD drive circuit (80 bits)
- Display duty selection ranging from 1/64 to 1/256
- Supports use of chip disable pin for lower large panel power supply dissipation
- Supports externally supplied bias voltage
- Operating power supply voltage/operating temperature include VDD (logic block) : 5 V ±10 % / –20 to +75 °C, VDD-VEE (LCD block) : 12 V to 32 V / –20 to +75°C
- Data transfer clock provides maximum 3.0 MHz and supports bidirectional shift
- 4-bit parallel data input
- Uses CMOS process
- 100-pin flat plastic package
Application Scenarios
This component can be used in various electronic displays that require large-scale dot matrix LCD segments. It's commonly used for automotive infotainment systems, home appliances, and medical equipment to display large amounts of information.
Comparison
Advantages- On-chip LCD drive circuit simplifies the design of the control board
- Supports lower large panel power supply dissipation with the use of a chip disable pin
- Performs bi-directional shift operation during data transfer, providing a faster data transfer rate
Disadvantages- Operational temperature is limited to -20 to +75 °C
- Not suitable for small displays due to its 100-pin flat plastic package
