Public displays in everyday use Large format LCD public displays are now to be found everywhere. As information displays they can be seen in all aspects of transportation, in hotels and museums, on the trading floors of international finance, in the medical sector, as well as in the monitoring and control rooms of manufacturing plants and for presenting detailed simulations.
As standard, functions are also incorporated which guard against image retention, i.e. burn-in, which is an ongoing danger. They not only guarantee excellent image reproduction but also extend the operating life of the display. A perfect technology in a designer outfit NEC‘s public display solutions sparkle with numerous innovative, technical characteristics, with a long product life span, as well as a high-quality, timeless and elegant design.
Numerous options for NEC’s LCD public displays Option slot All models in the MultiSync® 20 series and MULTEOS series come with an option slot, giving them great flexibility and the ability to be connected to almost anything. The option slot contains connections for a builtin PC, a CAT 5 receiver, an HD SDI board or a DVI daisy chain board.
Numerous options for NEC’s LCD public displays Built-in PC – A fully integrated PC module solution Most public display installations are controlled by one or several PCs, which often take up valuable space or have to be hidden from view for aesthetic reasons. Using NEC Display Solutions‘ built-in PC, NEC’s public displays with an option slot can be equipped with a fully functional PC – all fully integrated into the display without cabling or an external power supply.
Numerous options for NEC´s LCD public displays (HD)SDI card The (HD)SDI (High Definition Serial Digital Interfaces) standard is important, particularly within professional broadcasting, but also in the medical sector (e.g. in endoscopy). The optional (HD)SDI card has been optimised for NEC’s displays to allow such signals, as well as SDI signals, to be perfectly processed and imaged on the public displays. SDI signals up to 300m and HDSDI signals up to 100m distant are supported.
Panel technologies Innovative technologies for the best image reproduction One of the most important aspects of a public display is the LCD panel, since the quality of the panel largely determines the overall quality of the product. The design and construction of the public display needs to be as professional as possible in order to achieve the best possible panel operation. NEC Display Solutions therefore places the greatest importance on, for example, the thermal design of the display.
Variety of connectors HDMI port Interface variants HDMI = High Definition Multimedia Interfaces (1.0). A digital audio and video port, best known in the AV world, based on TDMS and compatible with DVI. HDMI and DVI ports are required in order to be able to receive and decode HDCP (High bandwidth Digital Content Protection) highdefinition, coded signals. HDMI ports are primarily to be found in Blu-ray or DVD players. However, HDMI cabling is also frequently present in professional installations.
Security / Reliability Protection against overheating with userdefined temperature limits for the fans Special heat/temperature sensors constantly monitor the temperature within the display. NEC’s public displays in the MultiSync® 20 series and the MULTEOS series contain respectively two or three fans which can be adjusted to switch on at a user-defined temperature limit.
Security / Reliability Enhanced protection against dust Self-diagnosis over the network Electronic devices are under constant attack from dust. In order to protect the LCD panel against excess dust, special measures have been employed in its construction. Using NaviSet® Administrator, NEC‘s displays can automatically send error messages about their component parts or other monitor malfunctions using the RS232-C standard or via DDC/CI, for example, if the lamp or printed circuit board is defective.
Security / Reliability Special security against theft Deactivation of sensor/keyboard People with sticky fingers won’t have a chance! The public displays can be secured against theft with the help of a PIN code accessed via the On Screen Display. Using the OSD function DISPLAY PROTECTION – CHANGE SECURITY PASSWORD an individually chosen password can be entered. The control buttons on the display can be deactivated using a given key combination so that unauthorised users can’t change the settings.
Colour management / Colour accuracy Programmable LUT Black level adjustments The MultiSync® public displays in the 20 series as well as the MULTEOS models come with a programmable 10-bit look-up table (LUT).
Medical applications DICOM mode GammaCompMD QA compatibility DICOM stands for “Digital Imaging and Communications in Medicine“. The DICOM standard enables the exchange and viewing of the same image information on different output devices with the same inherent image content and quality. Both NEC’s MULTEOS models and the MultiSync® 20 series come with the DICOM mode to allow the standardised reproduction of medical images.
Multifunctionality / Flexibility Perfect integration possibilities Various forms of image reproduction NEC’s public displays can be perfectly integrated into every kind of environment.
Video walls TileMatrix with TileComp Power-on-delay Up to 25 displays in a 5 x 5 matrix of appliances can be installed as a video wall using the TileMatrix function and commercially available graphic cards – all without additional hardware. The TileComp function simultaneously optimises multi-screen applications by smoothing out visual discrepencies, e.g. in the reproduction of curves across several screens. This enables a frameless display wall to be simulated without any annoying transitions.
User friendliness Settings adjustment On Screen Display The following options can be used to adjust the public displays: OSD menu directly in the display screen itself, infra-red remote control, DDC/CI or RS-232 port for remote settings adjustments, diagnosis and maintenance. Navigation through the On Screen Display has been simplified and improved, and made particularly user-friendly. All the main categories have been assigned to individual, easily-recognised menu icons.
Further product highlights High brightness Screensaver for static images Under certain conditions, NEC’s MULTEOS and MultiSync® 20 series public displays can achieve a very high brightness of 450 up to a max. 700 cd/m2. This makes for high legibility even in surroundings flooded with light (e.g. where there is bright sunshine). When the screensaver function is activated, the screen content moves in steps of two pixels and in the form of an “8“ with a time interval set by the user.
