1.4 Inch Square TFT LCD Display | RONEN

We build the 1.4 inch square TFT LCD display as a made-to-order TFT LCD module. The 240×240 panel format is held in our build library and released against your specification — active area, outline, luminance, touch and the electrical interface are all confirmed per project. This page lists the published format so you can check it against your enclosure before you send an RFQ.

1.4 inch square TFT LCD display 240×240 resolution 8bitMCU/SPI interface Built to order Optional capacitive touch

Built-to-order size. 1.4 inch is a panel format we tool and assemble on request — it is not part of the 193-module standard catalogue, which is listed in the main product range. Every other TFT LCD size we build is listed on the TFT LCD sizes we build to order index, and non-rectangular formats on the special shape displays page. Active area, outline, luminance and interface below are the published format; touch, brightness trim and operating range are confirmed per project.

1.4 inch TFT LCD module specifications

The table below is the published 1.4 inch format. Driver IC for the panel format is ST7789V2, viewing direction ALL, and colour depth 16.7M as standard — all confirmed on the datasheet released against your build.

Luminance is shown in cd/m²; where two figures appear the first is the minimum and the second the typical value. Driver IC, viewing direction and colour depth are confirmed on the datasheet released against your build.

1.4 inch TFT LCD module — what this page covers

This page is the specification reference for the 1.4 square TFT LCD display — covering the 1.4 inch TFT LCD module, the 1.4 inch square TFT LCD display, 1.4 inch TFT LCD module supplier and custom 1.4 inch TFT LCD display options, including the 240×240 resolution on a 8bitMCU/SPI interface, active area and outline dimensions, and luminance options.

How to specify a 1.4 inch TFT LCD module

Every project is released against the same parameter framework we use across our display range. The fields below are what we need from you to return a buildable module:

Display Size1.4 inch — or the active area in mm if your enclosure is already fixed
Resolution240×240
Module Interface8bitMCU/SPI — tell us the host and we recommend the match
Active Area / OutlineThe window in your enclosure, or the outline you must fit inside
Luminancecd/m² — indoor, high-brightness or sunlight-readable
Touch OptionNone / resistive / capacitive (CTP), with or without cover glass
Operating Temp.-20~70 °C operating

FAQ — 1.4 inch TFT LCD module

What resolution is available in 1.4 inch TFT LCD?

The 1.4 inch format is built on 240×240. We match the native pixel format so your host driver does not need to change — tell us the resolution and interface your controller already drives and we confirm the match on the datasheet.

What are the active area and outline dimensions of a 1.4 inch TFT LCD module?

The published active area and outline for the 1.4 inch build are 25.2x25.2 and 30x35x2.2. Send us the space available in your enclosure and we confirm the mechanical fit, including any FPC routing and bezel allowance.

What interface does the 1.4 inch TFT LCD use?

8bitMCU/SPI. We confirm the connector, signal timing and backlight driving as part of the released datasheet.

How bright is a 1.4 inch TFT LCD module?

The 1.4 inch panel format is specified at 800 cd/m². For sunlight-readable or outdoor positions, a high-brightness backlight with cover glass and optical bonding can be reviewed against your brightness and viewing-angle requirement.

What is the operating temperature range of a 1.4 inch display?

-20~70 °C operating. Wide-temperature variants and storage conditions are confirmed on the datasheet.

Is a 1.4 inch TFT LCD module in stock or built to order?

1.4 inch is a built-to-order size rather than a released catalogue part number. The in-stock modules listed above are released part numbers; if your enclosure accepts a different diagonal they ship from the standard range, and if the 1.4 inch outline is fixed we quote the build against your specification.

Can you supply a custom 1.4 inch TFT LCD?

Yes — that is exactly what this size is for. Tell us the diagonal or active area, the resolution, the interface and the outline you need to fit, and our engineers return a buildable module proposal with a datasheet and quotation.
