The module supports a typical 60 Hz frame rate with LVDS clock frequency around 71 MHz. It operates in DE-only mode (Hsync/Vsync tied low). Detailed power-on/off sequence and input signal timing ensure stable integration with industrial controllers and embedded boards.
The DBT121QXHA02 is purpose-built for tough industrial use cases where reliability, visibility, and durability are critical. Typical applications include:
Its wide temperature range, high brightness, and robust mechanical design make it especially suitable for environments with vibration, dust, and variable lighting conditions.
Engineered by Aptus Electronics, the DBT121QXHA02 combines premium optical performance with industrial-grade reliability. The high-brightness LED backlight ensures excellent readability under direct sunlight or bright workshop lighting. The wide viewing angle eliminates color shift for operators viewing from different positions. Low power consumption and efficient thermal design support 24/7 operation in enclosed cabinets.
The module undergoes rigorous reliability testing including high/low temperature storage/operation, thermal cycling, and damp heat testing to guarantee long-term stability. Its mechanical construction with precise mounting holes facilitates easy integration into custom enclosures.
