LC3251 / LC4751 Product Manual 5
Product Description
Planar® WeatherBright™ LC3251 and LC4751 displays are high bright, open-frame, liquid crystal, full
color digital displays intended for extreme weather, outdoor use. The displays utilize interlaced LED
backlights providing greater than 2000 nits of luminance for direct sunlight outdoor readability. The
displays are 32” and 47” diagonal sizes utilized in portrait mode with a 9:16 aspect ratio and with a
WXGA (1366x768) or FHD (1920x1080) native resolution, respectively. The WeatherBright displays
come standard with Planar’s ERO™ (Extended Ruggedness and Optics) technology, providing optically
bonded tempered vandal-resistant cover glass that delivers the best optical and physical performance.
Standard PC graphics DVI and VGA video inputs are accepted. An RS-232 serial connection enables full
system control and smart monitoring. Both displays accept 120V AC input and have rated power
consumption allowing them to run on a single 120V/15A standard electrical service.
The displays are designed to be field-serviceable with easy access for field cleaning or servicing. Field
replaceable components include LEDs, fans, and power supplies. The fans and power supplies are
redundant, allowing the displays to continue operating if these components fail with minimal effects to
the end-user experience. The system self monitors for any component failures or over-limit events and
continues operating in a safe but still functional mode until the unit can be serviced. In the event of a
component failure, fault flags are raised and can be accessed through the RS-232 serial interface using
a simple command set.
These LC3251 and LC4751 are open-frame displays intended to be mounted in NEMA 3R enclosures
that provide basic protection from the elements. The displays are ruggedized to utilize outside air for
cooling without the need for air conditioning. The enclosure is required to provide an intake and
exhaust for the air cooling with a replaceable standard air filter. It is recommended that the enclosure
provide a window opening for the display with no additional cover glass or window material in front of
the display. The ERO™ optically bonded displays will not experience any fogging, contamination, or
reflections that would otherwise compromise the image view ability over the life of the product.
