The 1.4 Inch TFT LCD Display Module is a compact yet high-performance square display solution engineered for modern portable and embedded systems. With a 240x240 dot matrix resolution packed into a 1.4-inch diagonal, this module delivers crisp, vibrant visuals in a miniaturized form factor, making it an ideal choice for handheld devices, vehicle-mounted equipment, wearable gadgets, instrumentation, and DIY electronics projects.
At the heart of this 1.4 Inch TFT LCD Display Module lies the advanced ST7789 driver chip, which supports 4-wire SPI interface (SPI-4L) for seamless, high-speed communication with popular microcontroller platforms including 8051, PIC, AVR, ARDUINO, ARM, and Raspberry Pi. The 10-pin FPC connection ensures reliable integration, while the 2.8V power supply voltage keeps power consumption low—perfect for battery-operated applications.
One of the standout features of this 1.4 Inch TFT LCD Display Module is its IPS technology, offering ultra-wide viewing angles of U80/D80/L80/R80. This ensures consistent color and contrast even when viewed from extreme side angles, ideal for dashboard displays or wearable screens where the viewing orientation varies. The module delivers 400cd/m² brightness, guaranteeing clear readability in both indoor and outdoor environments.
Durability and reliability are built into this 1.4 Inch TFT LCD Display Module, with an anti-static ESD protection rating of 8KV, safeguarding against electrostatic discharge during handling and operation. It operates flawlessly across a wide temperature range of -20°C to +70°C, making it suitable for demanding automotive and industrial settings.
This 1.4 Inch TFT LCD Display Module supports 65K/262K true color depth, reproducing rich, lifelike images and sharp text. All materials are fully compliant with environmental standards and RoHS requirements. Whether you are prototyping a smart wearable, upgrading a vehicle display, or developing a custom industrial panel, this 1.4 Inch TFT LCD Display Module combines compact design, robust performance, and exceptional visual quality to meet your project needs.
Specification of the 1.4 Inch TFT LCD Display Module
IPS Full-View Technology – A "Visual Revolution" for Small Screens
Conventional TN panels often suffer from color shift and washout when viewed off-angle. This issue becomes particularly noticeable when a screen is mounted on a wristband, a car dashboard, or other non-frontal viewing positions. The 1.4 Inch TFT LCD Display Module solves this problem with IPS technology, delivering U80/D80/L80/R80 symmetrical 80-degree viewing angles. This means:
- Colors and brightness remain consistent even when viewed from extreme sides, top, or bottom
- In vehicle-mounted equipment or handheld devices, users can read information clearly without facing the screen directly
- Combined with 400cd/m² brightness, the 1.4 Inch TFT LCD Display Module remains readable even under direct sunlight.
For smartwatches, fitness bands, and automotive HUDs, visual experience directly determines product competitiveness. The 1.4 Inch TFT LCD Display Module ensures your end-users enjoy premium display quality in every orientation.
SPI-4L Interface – The Balance Between Fewer Pins and High Speed
This 1.4 Inch TFT LCD Display Module adopts a FPC-10PIN + SPI-4L (4-wire serial peripheral interface) configuration, which is the mainstream connection method for small-sized displays. Its key advantages include:
- Fewer pins: Only 4 signal lines (SCK, MOSI, MISO, CS) are required, saving valuable GPIO resources on the host MCU;
- High speed: SPI clock rates can reach tens of MHz, sufficient for smooth animation rendering at 240x240 resolution;
- Broad compatibility: The 1.4 Inch TFT LCD Display Module works seamlessly with Arduino, STM32, ESP32, Raspberry Pi, and other popular platforms.
Compared to parallel interfaces (e.g., 8080), SPI offers slightly lower throughput, but for a 1.4 Inch TFT LCD Display Module with 240x240 pixels, it is more than adequate—while dramatically simplifying PCB routing and connector design.
Wide Temperature Range & ESD Protection – From Consumer to Industrial/Automotive Grade
Most consumer-grade LCDs are rated for 0~50°C, but this 1.4 Inch TFT LCD Display Module is specified for **-20~70°C**, along with ESD 8KV anti-static capability. This means:
- Reliable operation in freezing winter outdoor equipment or scorching hot vehicle cabins;
- 8KV ESD protection significantly reduces damage from electrostatic discharge during manufacturing, assembly, and daily use;
- The 1.4 Inch TFT LCD Display Module is ideally suited for automotive navigation, industrial handheld terminals, outdoor inspection instruments, and smart agriculture devices where durability is paramount.
This robust specification elevates the 1.4 Inch TFT LCD Display Module far above cheap "toy-grade" screens, making it a trustworthy choice for engineering projects.
FAQS About the 1.4 Inch TFT LCD Display Module
Q1: Does the module come with a touchscreen? A: The base version of this 1.4 Inch TFT LCD Display Module does not include touch, but an optional touch panel is available upon custom request.
Q2: How does 2.8V power supply work with 3.3V logic systems? A: The 1.4 Inch TFT LCD Display Module integrates an LDO or level-shifting circuit internally. 3.3V logic levels can directly drive the module without additional level translators.
Q3: What refresh rate can I achieve? A: With SPI-4L, the 1.4 Inch TFT LCD Display Module can reach 30–60 fps (depending on MCU clock speed and rendering algorithms), sufficient for general animations and even low-frame-rate video streams.
Q4: FPC cable length and connector type? A: Standard FPC length is customizable. The default is a 10-pin, 0.5mm or 1.0mm pitch connector – soldering or using a ZIF socket is recommended for the 1.4 Inch TFT LCD Display Module.
Q5: Are sample codes and documentation provided? A: Yes. Each shipment of the 1.4 Inch TFT LCD Display Module includes a datasheet, initialization code, pinout diagrams, and porting examples for major platforms.
