## LTA057A349F Datasheet: 5.7" QVGA Industrial Display
Engineered for Demanding Environments and Stable Performance
The LTA057A349F is a 5.7-inch a-Si TFT-LCD module designed for resilience in industrial applications, delivering clear QVGA resolution visuals. Its robust construction supports wide operational and storage temperature ranges, ensuring consistent performance where system uptime is critical. This display provides a practical solution for Human-Machine Interfaces (HMIs) and control panels that must function reliably under fluctuating thermal conditions.
Operational Integrity in Fluctuating Temperatures
The defining characteristic of the LTA057A349F is its broad operating temperature range of -20 to 70°C and a storage range of -30 to 80°C. This capability ensures that the display remains functional and reliable in environments that experience significant temperature swings, from refrigerated logistics centers to non-climate-controlled manufacturing floors. The thermal design mitigates the risk of display failure due to extreme cold or heat, a common pain point in industrial deployments. For systems where consistent visual output is directly tied to operational safety and efficiency, such as in heavy machinery or outdoor kiosks, this thermal resilience is a cornerstone of long-term value. What is the key benefit of its wide temperature range? It ensures operational continuity and reduces failure rates in thermally challenging industrial settings.
Built for Industrial and Commercial Integration
The LTA057A349F is well-suited for a variety of specialized applications where durability and clear visual feedback are paramount. Its design addresses the physical and environmental stresses common in these sectors.
- Industrial Automation HMIs: Provides a reliable operator interface for factory floor machinery, process control systems, and automated logistics, where temperature variations and mechanical vibration are common.
- Test and Measurement Equipment: Offers a clear and stable display for portable or benchtop diagnostic tools used in field service or laboratory environments that may not be climate-controlled.
- Transportation Systems: Suitable for in-cabin displays in commercial vehicles, public transit information panels, or marine electronics, where reliable operation across a wide temperature spectrum is essential.
- Medical Diagnostic Devices: Delivers consistent performance for patient monitoring systems or analytical instruments that require dependable visual data output.
For industrial HMIs that must operate from a cold start in winter to peak summer heat, the LTA057A349F's -20 to 70°C operating range makes it a highly reliable display choice.
LTA057A349F Key Technical Specifications
The technical parameters of this display are tailored for integration into industrial-grade systems, prioritizing reliability and functional clarity over high-end consumer features. The panel's thermal resistance, metaphorically acting like the diameter of a pipe, is designed to efficiently dissipate heat, which is crucial for maintaining its specified 20,000-hour backlight lifetime even at the upper end of its operating temperature.
| Parameter | Value | Engineering Significance |
|---|---|---|
| Screen Size | 5.7 inches | Provides a compact yet readable viewing area suitable for space-constrained control panels and portable devices. |
| Resolution | 320(RGB)×240 [QVGA] | Delivers clear and distinct rendering of essential graphical data, text, and GUIs for control and monitoring tasks. |
| Operating Temperature | -20 ~ 70 °C | Ensures functional reliability in a wide array of industrial settings, from cold storage facilities to hot factory floors, minimizing weather-related downtime. |
| Brightness | 320 cd/m² (Typ.) | Offers sufficient luminance for clear readability in typical indoor industrial and commercial lighting conditions. |
| Backlight Lifetime | 20,000 Hours (Min.) | Indicates a long operational life for the WLED backlight system, contributing to a lower total cost of ownership and reduced maintenance requirements. |
| Touchscreen | 4-wire Resistive Touch | Allows for reliable input with gloves or a stylus, a common requirement in industrial environments, and is less susceptible to EMI/RFI. For systems that need alternative user interfaces, the G057VN01 V2 offers a non-touch alternative. |
Frequently Asked Questions (FAQ)
What is the primary interface for the LTA057A349F?
The display utilizes a 33-pin CMOS interface with 6-bit color depth for each RGB channel, a common and straightforward interface for embedded system integration. How is data integrity ensured with this interface? The CMOS signal standard is robust and well-documented, simplifying the connection to a wide range of microcontrollers and display drivers.
Does the display module include a backlight driver?
No, the LTA057A349F is equipped with a WLED backlight but requires an external driver. This allows system designers the flexibility to select a driver that best fits their specific power supply and control requirements, such as PWM dimming or thermal protection schemes.
For engineers designing systems that must perform consistently across a wide thermal spectrum, the LTA057A349F offers a proven and durable display foundation.
