1.3-Inch High-Definition IPS LCD Display Module with 240x240 Resolution and ST7789 Driver

This compact 1.3-inch plug-in display module provides a full-colour visual interface for your electronics projects. Its core is a high-definition IPS (In-Plane Switching) panel, which offers more vivid colour reproduction and superior viewing angles compared to conventional TFT LCD screens. With a square 240 by 240 pixel resolution and a measurable 23.4mm by 23.4mm viewing area, it is well-suited for applications requiring clear numeric, graphic, or icon-based information. The module’s flexible dual-interface design, featuring both an 8-bit parallel port and a 4-wire SPI, allows it to integrate with a wide range of microcontrollers and development boards, defaulting to the parallel connection for straightforward initial use.

Features and Construction

This display module combines a specific set of electronic and mechanical specifications to deliver a reliable visual output component. Its construction is focused on providing a ready-to-use core display system that requires only the addition of standard pin headers to become fully operational.

Material and Build

The key visual component is an IPS LCD panel. This In-Plane Switching technology is known for delivering more accurate and consistent colour across wider viewing angles compared to traditional TFT screens. The display is driven by an ST7789 control chip, which manages the pixel data to produce the final image. The module arrives as a single integrated printed circuit board (PCB) measuring 27.78mm in width by 39.22mm in length, housing the screen, driver, and interface circuitry.

Size and Practical Fit

The module’s compact dimensions are broken down into two key measurements: the active screen area and the total board size. The usable viewing area is a precise 23.4mm square, which displays the full 240x240 resolution. The overall physical footprint of the module is 27.78mm by 39.22mm, making it a space-efficient choice for projects where panel space is limited. This size makes it applicable for integration into portable devices, custom instrumentation panels, or compact control units.

Uses and Placement

With its specific technical profile, this display module finds utility in both hobbyist and professional electronic environments. Its combination of a clear square screen, robust operating range, and interface flexibility supports a variety of implementations.

Event or Professional Use

For professional or event-based applications, this module can serve as a reliable status or data display. Its wide operating temperature range of -20 to 70 degrees Celsius allows it to function in environments that are not climate-controlled, such as industrial monitoring equipment, outdoor sensor readouts, or portable data loggers. The full viewing direction ensures that information remains legible to operators or viewers from various positions around a device.

Everyday Home Use

For home or workshop projects, this display is ideal for creating custom user interfaces. Hobbyists can use it to build smart home control panels, weather stations, retro gaming consoles, or system monitors for computers and networks. The default 8-bit parallel interface is often simpler to connect for beginners, while the SPI option provides a pathway for more advanced projects requiring fewer control pins on the host microcontroller.

Benefits and Buying Value

Choosing this specific module provides clear, source-supported advantages centred on its visual quality, integration options, and operational resilience. It represents a component-focused value proposition for anyone needing a small, colour display.

Reuse and Low Maintenance

As a solid-state electronic module with no moving parts, it requires no ongoing maintenance beyond operation within its specified parameters. Its design allows it to be reused across multiple projects or prototypes. The inclusion of both parallel and SPI interfaces means it can be adapted to different host systems over time without needing a different display, offering long-term utility in a developer's component inventory.

Why Choose This Product

This product stands out for providing a measurable IPS screen upgrade over basic TFT displays in a compact, well-defined package. The concrete specifications—the 1.3-inch size, 240x240 resolution, 23.4mm viewing area, and ST7789 driver—allow for precise planning in product design. The need to source and solder the 18-pin header is a clear consideration, but it also allows users to choose a connector height that perfectly suits their enclosure, offering a customisable final fit.
