Product Overview

The 4.2 inch Monochrome LCD ST7301 300×400 MCU/SPI are single-color reflective type displays that present information without the use of multiple hues. They are often utilized in devices where the primary goal is to convey data in a clear and readable format, such as Handheld & PDA, digital clocks, and industrial equipment.

The 4.2 inch Monochrome LCD comes with MCU/SPI signal interface, low power consuption, IF042MU30-40 also features a normally white, reflective display with a 300×400 pixel resolution. Which ensures that the display remains visible under direct sunlight.

4.2 inch Monochrome LCD Features

Viewing Angle and Orientation

With its 12 o’clock viewing angle, the IF042MU30-40 allows users to see the screen clearly, even when viewed from above. This is particularly useful in applications where the device must be mounted at an elevated position.

Power Consumption

The 4.2 inch Monochrome LCD reflective display is low power consumption, which makes it an energy-efficient choice for battery-powered devices and systems with limited power resources.

ST7301 Driver IC

The ST7301 is a driver IC that powers the IF042MU30-40, enabling it to display crisp, clear images. This powerful chip supports both MCU and SPI interfaces, with 12 pin and 20 pin variants available. By integrating the ST7301 driver IC, the 4.2 inch LCD can deliver high-quality visuals with minimal power consumption.

MCU and SPI Interfaces

The 4.2 inch Monochrome LCD can be connected to a microcontroller or other system components using either an MCU (Microcontroller Unit) or SPI (Serial Peripheral Interface) interface. These interfaces allow for seamless communication between the display and the controlling device, ensuring smooth operation and quick response times.
