1.4 inch TFT Module | 240x240 SPI square TFT display module | ST7789

1.4 inch TFT Module is a high-performance TFT display solution designed for high-reliability scenarios. It is equipped with a 1.4-inch full-view screen with a resolution of 240×240 pixels. It uses RGB three-color vertical arrangement technology to ensure bright colors and delicate pictures. Its core driver chip ST7789 supports SPI 3L/4L interface, with an operating voltage range of 2.6V~3.3V and strong compatibility. It can be widely used in industrial control, smart wearables, medical equipment and outdoor display.

This 1.4 inch TFT Module performs well in extreme environments, with an operating temperature range of -30℃ to +80℃ and a storage temperature range of -20℃ to +70℃, meeting the requirements for stable operation in harsh environments. The typical brightness is 400 cd/m2, combined with a constant current drive design, it can maintain clear visibility even in strong light environments. To prevent LCD screen image retention, the product has specially optimized the display protection mechanism. It is recommended that users use dynamic images or black backgrounds as screen savers and refresh static content every 2 minutes to effectively extend the screen life.

In terms of structural design, the 1.4 inch TFT Module adopts precision manufacturing technology, and the mechanical dimension tolerance is strictly controlled within ±0.3mm. The assembly tolerance of key components such as PCB and TFT is less than ±0.2mm, ensuring the compactness and reliability of the overall structure. The interface layout is simple and efficient, and the built-in drive circuit supports full-directional display (Full O'Clock), and users can flexibly adapt to different installation directions. In addition, the backlight driving conditions and signal pin design have been optimized to take into account low power consumption and high response speed, providing a plug-and-play convenient experience for embedded systems.

This 1.4 inch TFT Module HTM-H014A3-SPI-V0 has become an ideal choice for industrial automation, consumer electronics and outdoor equipment with its high precision, strong environmental adaptability and long-term display protection characteristics, helping users create stable and durable terminal products with professional quality.
