Simplifying touch screen technology Choose the wrong type of touch screen technology and it may not be the best for your specific needs. NEC aims to simpify the solution...
NEC MultiSync® X-series for video walls
NEC MultiSync® P-series of public displays
NEC display solutions NEC has a range of LCD desktop, large format monitors and touchscreens for various applications within training, education, public sector applications and public displays. The NEC MultiSync® P-series of professional, high definition (1080p) public displays, designed for 24/7 operation, such as in reception and other public areas. They can be used on their own to display information, or by using an optional NEC slot-in PC and digital signage software, can be used for signage applications. The P-series has DICOM support for medical applications in University teaching hospitals. An important feature for medical training is the Programmable Ambient Light Sensor for reduced power consumption and eye pleasing brightness levels. Features of the P-series include daisy chaining via DVI (max 9 units) and DisplayPort (max 25 units); TileMatrix (10 x 10) so that you can build up a matrix of up to 5 monitors by 5 in size so that video walls can be created over 5 metres wide by 3 metres tall without needing any additional hardware; OSD rotation to portrait mode; PIN as theft protection and various picture in picture options.

NEC, together with its solutions partners, then takes its original P-series screens and add various components to provide a variety of solutions. For example, the P552 55” screen is stand-alone; the P552PG has the addition of protective glass (PG) for vandal-proof protection where screens are sited in public areas; P552-DST is a fully integrated touch screen using Dispersive Signal Technology; P551PCT is a fully integrated touch screen using Projected Capacitive touch technology; P701-OSTU is a 70” P-series screen with Next Windows Optical Sensing technology (OST) with USB interface (U). Touch screen technology is also integrated into other series of NEC screens. For example, the NEC V-series is available with DST and OST touch screen technology. The NEC V-series from 32” to 65” are entry level public displays, ideal for education use, although these should not be used where they need to be in operation for long lengths of time. The MultiSync® X-series of specialist public displays are second generation video wall screens with a mere 6.7mm bezel for impressive video walls. With heavy duty performance and high brightness, they are ideal for displaying information about your education services in the schools/university’s main reception area. This series also includes DICOM support. As with the P-series there are a number of features including TileMatrix to build a matrix of up to 5 monitors by 5.

NEC DST touch solution
The range of NEC P-series in sizes 40”, 46” and 55” are fully integrated DST (Dispersive Signal Technology) touch solutions by 3M. The sensor is installed behind the original NEC bezel and gives a fast accurate repeatable touch. DST touch technology works with vibration. This works on taps rather than touch and is therefore ideal for annotation applications or where you want to install the LCD touchscreens into tabletops. You could put your hand on the table and it would recognise that you weren’t touching it, but when you tap to touch, it would recognise that and act accordingly. It is not good for drag and drop nor mission critical applications. 3M DST touch technology is very robust and does not a require special input device nor a clean surface as the technology relies on ‘bending waves’ for locating the point of contact with the surface. The screen can be touched with bare hands or gloves and sensitivity is not affected by dirt, grease or scratches.

These screens require no recalibration in either a vertical (portrait and landscape) or horizontal position (tabletop). You can use these screens with an optional NEC slot-in PC for digital signage applications, when you will also need digital signage software that has touch screen support, such as Repeat Signage.
NEC PCT touch solution The range of NEC P-series in sizes 40”, 46”, 55”, 65” and 70” are fitted with a fully integrated Projected Capacitive touch screen (PCT). The sensor is installed behind the original NEC bezel and offers Windows® 7 dual touch capability. It features a resilient all glass touch sensor, ideal for vandal resistant applications offering resistance to scratching and gouging. The sensor is located behind the glass and cannot be interfered with by the user. PCT technology can operate behind weather-resistance or vandal-resistance glass. It can also be installed behind windows, for example, in a school, college or university foyer’s window. Projected capacitive touch uses finger or stylus. Works with bare hands or gloves.

NEC OST touch solution The patrolled NEC P-series in size 70” are fitted with a fully integrated Next Window Optical Sensing touch screen. The sensor is installed behind the original NEC bezel and offers Windows® 7 dual touch capability. Annotations are fast and precise making this touchscreen the ideal solution where handwriting and creative drawing are the principle requirements. Optical sensing technology (OST) has cameras in the corner of the screen and a reflective strip, so that it knows when you are touching the screen. The bezel (surround) on optical sensing touch screens is a little bigger to incorporate the cameras. Care should be taken when cleaning as cameras in the corner under the bezel can attract dust and dirt. Touch is activated by bare fingers, gloved fingers or a stylus.
Touchscreens that use Optical Sensing technology are not robust, nor vandal resistant and are not suitable for public display unless sited in a monitored area, for example, in reception with staff presence or museum patroled by security.
