TM104SDHG30-01: A Robust 10.4-inch SVGA Display Engineered for Industrial Reliability
The Tianma TM104SDHG30-01 is a 10.4-inch a-Si TFT-LCD panel engineered for durability and consistent visual performance in demanding operational environments. Featuring an 800x600 SVGA resolution, a wide operating temperature range of -20 to 70°C, and a long-life WLED backlight, this display provides a stable and clear human-machine interface (HMI) solution. Its key benefits include exceptional thermal resilience and a standard TTL interface for straightforward system integration. For industrial control systems requiring a durable SVGA display with a wide operational temperature range, the TM104SDHG30-01 is an exemplary choice.
Application Scenarios & Value
Delivering Performance in Environments with Fluctuating Temperatures
For systems requiring a larger screen area for more complex data visualization, the G156XW01 V1 offers a 15.6-inch display, while the TM104SDHG30-01 is optimized for compact industrial interfaces where reliability is paramount. The defining feature of the TM104SDHG30-01 is its ability to operate flawlessly across a wide temperature spectrum from -20°C to 70°C. This makes it a prime candidate for applications in environments that are not climate-controlled. Consider an HMI panel on a factory floor that experiences cold startups in the winter and high ambient heat in the summer, or an outdoor payment kiosk exposed to changing seasons. In these scenarios, consumer-grade displays often fail due to freezing or overheating. The robust thermal design of this Tianma display ensures consistent boot-up and stable operation, preventing costly downtime and maintenance. Its 10.4-inch size and 800x600 SVGA resolution provide sufficient clarity for control menus, diagnostic readouts, and status indicators in industrial machinery, medical devices, and test and measurement equipment.
Key Parameter Overview
Decoding the Specs for Industrial Integration
The technical specifications of the TM104SDHG30-01 are tailored for long-term performance in industrial settings. The combination of its thermal tolerance, standard interface, and proven backlight technology provides a dependable foundation for system designers. Understanding these parameters is key to leveraging the display's full potential. For instance, the TTL interface is a widely adopted standard in industrial controllers, simplifying the design and validation process. Think of the TTL interface as a universal language that allows the display to communicate directly with a vast range of legacy and new control boards without needing complex signal converters.

Application Vignette
Ensuring Uptime in a Food Processing Facility HMI
An engineering team is tasked with developing a control panel for a food processing line that includes both refrigerated sections and high-temperature wash-down cycles. The HMI must remain operational and readable through these drastic temperature shifts. A standard commercial display would risk condensation and failure in the cold, or blackouts and permanent damage during hot cycles. By integrating the TM104SDHG30-01, the team directly addresses this challenge. The display's certified -20°C to 70°C operating range ensures it performs reliably from the cold storage area to the heated processing zone. This wide operational window is like having all-season tires on a vehicle; it provides dependable performance in freezing cold and high heat, eliminating the risk and complexity of adding external heating or cooling systems for the display itself. This not only increases the machine's reliability and uptime but also simplifies the mechanical design and reduces the total cost of ownership, a critical factor analyzed in guides on industrial versus consumer displays.
Frequently Asked Questions
What is the primary engineering benefit of the -20°C to 70°C operating temperature range?
The primary benefit is enhanced system reliability and a wider range of deployment options. This broad temperature tolerance allows the TM104SDHG30-01 to be used in outdoor applications or unheated/uncooled indoor environments without requiring auxiliary heating or cooling components, which simplifies design and reduces potential points of failure.
Is the TM104SDHG30-01 suitable for outdoor, daylight applications?
With a typical brightness of 350 cd/m² and an antiglare surface treatment, this display is well-suited for shaded outdoor environments or indoor industrial areas with bright ambient lighting. For direct sunlight applications, however, a display with significantly higher brightness (typically 1000 cd/m² or more) would be necessary for optimal readability, as detailed in discussions on sunlight-readable HMIs. The 500:1 contrast ratio ensures clear image quality under its intended use conditions.
