The Kyocera KCG057QV1EA-G000 is a 5.7-inch QVGA color display engineered for consistent performance in demanding industrial environments. It delivers a unique combination of time-tested technology and robust operational parameters, featuring key specifications such as 320x240 QVGA | 250 cd/m² | 0 to 60°C Operating Temp. This module's primary benefits include operational stability across a wide temperature range and simplified system design through its integrated backlight technology. Best fit for maintaining or developing cost-sensitive industrial controls that require proven display technology with a wide operational temperature range.
Application Scenarios & Value
Ensuring Readability and Uptime in Dynamic Industrial Settings
For engineers designing or maintaining Human Machine Interfaces (HMIs) for factory automation, process control, or test and measurement equipment, ensuring consistent readability and long-term reliability is paramount. The KCG057QV1EA-G000 directly addresses this challenge. Consider a control panel for a CNC machine or a PLC interface located on a factory floor where ambient temperatures can fluctuate. This display's operational range from 0°C to 60°C ensures stable performance without requiring complex external heating or cooling systems. Its CSTN (Color Super-Twisted Nematic) screen provides clear, color-differentiated information necessary for quick operator assessment. The CCFL backlight system, while a mature technology, provides a brightness of 250 cd/m², which is ample for typical indoor industrial lighting conditions, ensuring that critical data is always visible. For systems requiring a different form factor or specifications, the related KCG057QV1DB-G000 offers an alternative within the same family, enabling targeted selection based on specific design constraints.

Frequently Asked Questions (FAQ)
In-Depth Answers for Engineering Decisions
How does the CCFL backlight impact the design of an industrial device?
The use of a Cold Cathode Fluorescent Lamp (CCFL) means the display requires a high-voltage inverter to operate, which this module does not have built-in. This is a critical design consideration. While the CCFL provides a long typical lifetime of 54,000 hours, engineers must account for the inverter's board space, power draw, and potential for EMI. Understanding the total cost of ownership is key, a topic further explored in our guide on industrial vs. consumer displays.
What are the practical advantages of the 0°C to 60°C operating temperature range?
This temperature range ensures the display functions reliably in enclosed, non-climate-controlled environments, such as equipment racks, factory floor consoles, or portable test units. It eliminates the need for specialized heating components that would be necessary for standard consumer-grade displays to operate near freezing, simplifying the thermal design and reducing the overall system cost and complexity. You can learn more about designing for challenging conditions in this guide to reliable displays in heavy machinery.
Is the CSTN panel's response time suitable for modern HMI applications?
With a typical response time of around 180/170 ms (Tr/Td), this CSTN display is best suited for applications showing static or slowly changing information, such as numerical readouts, status indicators, and basic menus. It is not intended for displaying full-motion video or rapidly moving graphics. Its strength lies in providing a cost-effective and clear color interface for traditional Industrial PC and control applications where data clarity and reliability are prioritized over video-rate performance.
