Product Specifications

Applications

This module is perfectly suited for commercial digital signage, display terminals in control systems, kiosk displays, and both landscape and portrait installations. Its robust design and wide compatibility make it ideal for professional AV integrators and OEM manufacturers seeking reliable high-resolution open cell solutions.

Interface and Signal Specifications

The panel uses a 51-pin GT05S-51S-H38-E1500 or compatible LVDS connector supporting JEIDA or VESA data formats (selectable via SELLVDS pin). It features dual-port LVDS input with even/odd pixel channels, I2C for control (SCL/SDA), and standard CMOS interface signals. The module operates in DE-only mode, simplifying integration with modern timing controllers while maintaining full compatibility with 60Hz frame rates and 74.25 MHz clock frequency.

Optical and Performance Characteristics

With a typical contrast ratio of 1000:1 and 89-degree viewing angles across all directions, the DBT550BHN51L035A ensures clear visibility from almost any position. Color coordinates are precisely calibrated (white: 0.270/0.293, red: 0.644/0.337, etc.), delivering natural and vibrant reproduction. The anti-glare surface treatment minimizes reflections in bright environments.

Power Sequence and Reliability

Proper power sequencing is required to protect the panel: VDD must stabilize before interface signals become valid, and the backlight enable follows after valid logic signals. The module meets strict reliability standards with an operating temperature range of -20°C to +70°C and storage from -30°C to +80°C.
