Screen for outdoor digital signage

At the end of 2014, the MultiSync X474HB large format display was launched by NEC Display Solutions, and it is one of the centrepieces of the company’s ISE 2015 stand.

Targeted at digital signage applications in high-brightness environments requiring sunlight-readable operation, the 47in LCD display is designed to intelligently adapt to its surroundings, offering a bright, clear image when required, without wasting energy when it’s not. With brightness of up to 2000 nits – nearly three times that of most other NEC large format displays – the company says that the X474HB is easily visible in shopping windows or cabinets for outdoor applications.

“Large-format LCD displays often struggle to be as effective in unshaded outdoor conditions where the temperature and brightness of sunlight wash out the image,” said Tobias Augustin, product manager public display solutions at NEC Display Solutions Europe. “To compensate, these displays are often run at maximum brightness, wearing out the display lifetime faster whilst image performance is still unsatisfactory.

“NEC’s X474HB display addresses these issues with a high brightness display that is designed to cope with the durability and readability challenges often arising in sunlit areas. As such, this display is ideal for any heavy-duty digital signage application that requires enhanced visual performance, flexible control and connectivity as well as long operating hours.”

The 10-bit colour S-IPS panel with direct LED backlight is said to ensure optimal visual ergonomics thanks to deeper black levels, improved contrast and readability and lower power consumption. The X474HB also features a 110°C TNI, meaning the liquid crystals won’t distort and go black in the heat of direct sunlight.

As well as a full high-definition high-brightness panel, the display incorporates a ShineOut Anti-Glare coating, and a Quarter-Lambda optical filter is used to overcome polarisation of light emitted by the display.
