The 3.4-inch Bar-Type TFT Display represents a specialized visual solution engineered for applications where standard screen proportions fall short. With its distinctive 412x960 pixel resolution and a compact 3.4-inch diagonal, this bar-type format delivers an elongated aspect ratio ideal for presenting vertical content, status bars, instrumentation panels, or graphical interfaces within narrow mechanical enclosures. The display's active area measures 33.99mm x 79.2mm, while the overall module thickness is an ultra-slim 2.00mm, enabling seamless integration into space-constrained portable electronic devices and industrial control systems.
Optical performance is anchored by IPS full viewing angle technology, guaranteeing consistent color reproduction and contrast from all directions, with optimal viewing angles specified at U85/D85/R85/L85. A brightness level of 350 cd/m² ensures clear visibility in typical indoor environments; should your project demand higher luminance for outdoor or high-ambient-light conditions, the backlight configuration can be customized—by adjusting LED quantities and drive conditions—to meet specific requirements. The 3.4-inch Bar-Type TFT Display is built to endure harsh operating environments, supporting a wide temperature range from -30°C to +80°C, making it equally reliable in freezing cold storage facilities and high-temperature industrial machinery. Additionally, the module incorporates robust anti-static ESD protection up to 8KV, safeguarding sensitive electronics during assembly and operation. With a 3.3V supply voltage and an ST7701S driver IC, this display balances low-power consumption with responsive performance. It is fully RoHS compliant, reflecting a commitment to environmental standards and safety.

Technical Highlights & Integration Insights of the 3.4-inch Bar-Type TFT
The 3.4-inch Bar-Type TFT Display distinguishes itself through a combination of advanced technical features that simplify system integration while ensuring reliability. At its core, the ST7701S driver controller provides a flexible RGB interface via a 40-pin FPC, supporting a wide range of host processors commonly found in industrial and portable devices. This interface architecture allows for seamless video signal transmission, making it straightforward to drive complex graphical user interfaces without requiring extensive redesign. To further ease hardware integration, we offer a matching solder-type FPC connector that enables quick, secure, and repeatable connections—ideal for prototyping, production, and field servicing.
One of the most critical technical highlights is the display's wide operating temperature range of -30°C to +80°C. Unlike consumer-grade screens that degrade under thermal stress, this model is designed with industrial-grade materials and assembly processes to maintain optical performance and electrical stability across extreme conditions. The anti-static ESD protection (8KV) adds an extra layer of robustness, reducing the risk of damage from electrostatic discharge during handling or in electrically noisy environments such as factory floors or portable equipment exposed to dry conditions.
For developers, integration is supported by a complete tutorial package that includes interface specifications, demonstration code, and a development kit. This resource significantly reduces time-to-market by providing validated hardware reference designs and software drivers. Whether you are implementing the 3.4-inch Bar-Type TFT Display in a new product or upgrading an existing system, the availability of these materials ensures that hardware interfacing and initial bring-up are efficient and predictable. Moreover, brightness customization options allow the same base module to be adapted for different lighting environments, giving designers the flexibility to maintain a common mechanical footprint across multiple product variants while tailoring luminance to specific use cases.
Key Technical Considerations When Purchasing A 3.4-inch Bar-Type TFT
Before integrating the 3.4-inch Bar-Type TFT Display into your project, several technical factors should be carefully evaluated to ensure optimal performance and seamless integration.
1
Interface and Connection Method
This model uses an RGB interface via a 40-pin FPC, requiring proper pin mapping and signal timing configuration. While the provided development kit and demonstration code simplify this process, verifying compatibility with your host processor's RGB output capabilities is essential. For a more straightforward hardware connection, our optional solder-type FPC connector is highly recommended, as it eliminates the need for custom cabling and provides a reliable, repeatable interconnect.
2
Environmental Requirements
The 3.4-inch Bar-Type TFT Display is rated for -30°C to 80°C operation; if your product will face extreme thermal cycles or high humidity, consider additional mechanical protection or conformal coating. Built-in ESD protection up to 8KV addresses many static-related concerns, yet system-level grounding and enclosure design should also be reviewed to maximize durability.
3
Brightness and Touch Functionality
The standard 350 cd/m² brightness suits indoor environments. If the display will be used in direct sunlight or high-ambient-light conditions, customizing the backlight for higher luminance is available. The base model is a non-touch version; a variant with capacitive touch is offered for interactive applications.
4
Comprehensive Support Package
Request the interface specifications, demonstration code, and development kit prior to mass production to significantly reduce engineering effort and mitigate integration risks.
By addressing these technical considerations upfront, you can ensure that the 3.4-inch Bar-Type TFT Display delivers reliable, long-term performance in your specific application environment.
