55 inch TFT LCD Panel for Industrial Systems - P550HVN04.2

The AUO P550HVN04.2 is a 55-inch industrial TFT-LCD panel engineered for digital signage deployments, delivering Full HD 1920(RGB)×1080 resolution on a dual a-Si TFT-LCD architecture. With 700 cd/m² brightness, 4000:1 typical transmissive contrast, 99% sRGB coverage and a WLED backlight rated for 60,000 hours, it provides consistent, colour-accurate imaging for long-duty commercial display installations. The panel drives through a dual-channel LVDS (8/10-bit) interface at 24.0±1.2V, offering system integrators a reliable, power-efficient platform for building multi-panel signage walls and standalone information displays.

What are the key display specifications of the AUO P550HVN04.2?

The P550HVN04.2 is a 55-inch a-Si TFT-LCD (Dual) digital signage panel operating in transmissive, normally black AMVA3 mode. It delivers 1920(RGB)×1080 Full HD resolution at a 0.210×0.630 mm pixel pitch, with a 60Hz refresh rate and 6.5 ms typical G-to-G response time.

How bright is the panel and what is its contrast ratio?

Brightness is rated at 700 cd/m², with a typical contrast ratio of 4000:1 in transmissive mode. Viewing angles are specified at 89/89/89/89° (typ., CR≥10), helping maintain image consistency across wide audiences typical of public signage installations.

What colour performance can be expected from this panel?

The panel supports 16.7M/1.07B colour depth (8-bit / 8-bit + Hi-FRC) and covers 99% of the sRGB colour space (CIE 1931), with a specified colour temperature of 9969K — suitable for branded retail and corporate content requiring consistent colour rendering.

What interface and power requirements apply for system integration?

The panel uses a dual-channel LVDS interface (2 ch, 8/10-bit) and requires a 24.0±1.2V input supply. Power consumption is 183.12 W typical and 189.36 W maximum. Logic voltage for the LVDS interface is not specified in the manufacturer data and should be confirmed with AUO before design-in.

What is the backlight configuration and service life?

Backlighting is provided by WLED (white LED) technology with a typical lifetime of 60,000 hours, supporting long-running commercial signage duty cycles with reduced maintenance interventions.

What environmental conditions are supported?

The specified operating temperature range is 0°C to 50°C, with a storage temperature range of -20°C to 60°C. For unsheltered outdoor use or installations exposed to temperature extremes, thermal management and environmental protection must be engineered into the enclosure.

What are the physical dimensions and mounting considerations?

The outline dimension is 1363.2×816.2 mm (H×V) with an active area of 1209.6×680.4 mm (H×V), and the panel weighs 30 kg. These figures should be used directly when designing bezel, frame and structural mounting solutions for fixed installations.
