TIANMA TM104SDHG30

The TIANMA TM104SDHG30, manufactured by Tianma Microelectronics, is a reliable industrial-grade TFT LCD display module widely used in automation, instrumentation, and embedded systems. It features a 10.4-inch diagonal size with a resolution of 800×600 pixels (SVGA), delivering clear and stable visuals for graphical user interfaces, monitoring dashboards, and control panels.

This display uses a 4:3 aspect ratio, which is ideal for legacy industrial equipment and traditional HMI systems. It supports 262K / 16.7M colors (6-bit / 8-bit with FRC), providing adequate color reproduction for industrial visualization and interface elements.

The panel is based on TN (Twisted Nematic) transmissive technology, offering stable performance with typical viewing angles of around 70/70/60/70 (CR≥10). It generally provides a brightness of ~350 cd/m² and a contrast ratio of about 500:1, making it suitable for indoor industrial environments.

For backlighting, the module uses a White LED (WLED) edge-lit system with a long lifespan (around 30,000–50,000 hours depending on variant). The LED backlight improves energy efficiency and ensures uniform illumination across the display.

The interface of this display is a parallel RGB interface (6-bit / 8-bit) with a 60-pin connector, allowing compatibility with a wide range of embedded controllers, industrial PCs, and driver boards. It typically operates on a 3.3V supply, making integration straightforward in standard industrial systems.

Mechanically, the module has a compact and rugged design with approximate dimensions of 228.4 × 175.4 × ~6.5 mm and an active area of 211.2 × 158.4 mm. It supports a wide operating temperature range of -20°C to +70°C, making it suitable for demanding industrial environments
