NEC Whitepaper: Commercial Monitors Vs. Consumer TVs

Commercial Grade Large Format Displays Vs. Consumer Televisions
Brightness
Depending on the ambient light, it is necessary to have a minimum brightness level
to guarantee sufficient visibility. Typically, airports and modern offices are flooded
with light via glass atriums and facades, these and other equally bright spaces
require displays to deliver brightness of 700cd/m² or even more, however, domestic
televisions rarely surpass 300cd/m². Large format displays usually provide a high
(≥700cd/m²) or moderate (350-500cd/m²) brightness output suitable for common
light conditions, ensuring effortless readability even in challenging circumstances.
Uniformity
Using high-end components, professional LFDs aim to achieve the best possible
picture quality without compromise, while televisions prioritize competitive
consumer pricing over quality. NEC displays take even further steps towards
superior imaging by using special diffuser sheets for best uniformity. This
technology balances brightness levels across the entire surface area to prevent dark
spots at the edges of the display.
Reflection
Reducing the surface reflection in addition to a sufficient brightness level is one of
the key advantages of commercial grade large format displays. In doing so, NEC relies
on an advanced anti-reflection haze filter. The anti-glare surface treatment reduces
reflection to a minimum and achieves advanced visual conditions even in a bright
environment. Even when installed in situations where there is an influx of ambient
light, such as the check-in counter an an airport, the high haze filters will minimize
the reflection of this light and ensure the the content is visible to onlookers.
Color accuracy
Professional large format displays often have pre-calibrated factory settings to
guarantee accurate colors. In addition, colors can either be individually adjusted via
the OSD or calibrated externally ensuring customers can achieve exactly the picture
they want. The situation with consumer TVs where this professional calibration is
not available could cause colors to look blurry and washed out. Most NEC displays
feature a SpectraView™ Engine which is constantly running in the background to
control the parameters of the display regarding color accuracy, uniformity and aging.
This is very important for customers where accurate color reproduction is vital.
Visual requirements
In general, the purpose of a large format display, in all application areas, is to show content. Often, it is required to attract viewers and make them aware of important
information or to highlight advertisements via digital signage. Therefore, it is paramount to aspire to the best possible visual conditions regarding your content and ensure
flawless visibility. To achieve peak picture quality, there are various aspects to consider.
Higher brightness levels with professional LFDs
Reliable and natural color reproduction with SpectraView
Clear image perception
thanks to reduced glare
Visual disturbances due to
glossy screen surfaces
Poor color reproduction without calibration functionality
Lower brightness from consumer TVs
