Mitsubishi Electric has announced the addition of direct view LED to its portfolio with the release of the VS-15NP160 (15-NP) narrow pixel pitch (NPP) LED screen.
The 15-NP is designed specifically for control rooms and other demanding indoor applications such as TV studio backdrops. It incorporates many of the key technologies of its existing DLP and LCD displays, along with several patented features to enhance long-term reliability, energy efficiency and performance.
Designed and built by Mitsubishi Electric in Japan, the 15-NP delivers a light output of 800 cd/sqm, which together with its high contrast ratio and seamless screen surface, makes it an ideal choice for SCADA-type applications. A new patented anti-burn feature allows static graphics to be displayed for long periods of time without adversely affecting performance or lifespan. The 15-NP is rated for 100,000 hours of continuous operation, with its anti-burn feature ensuring that LED luminance and chromaticity remains uniform over the lifetime of the screen.
Unlike DLP rear projection, light output per square metre is constant and independent of the total screen area, meaning that it is possible to create daylight-viewable displays of any size. Display depth of only 90mm means that it can be installed virtually anywhere, and both front and rear access versions are available to further increase versatility.
The 15-NP is based on a 1.5mm pitch, three-in-one SMD LED package developed especially for this application. Displays are assembled on site as required from individual LED units measuring 480mm x 540mm. LED units feature standard OPS slots, which can accommodate OPS 3G-SDI-input boards or OPS HDBaseT inputs for long-distance signal transmission via Cat6(STP) cable. Dual-loop signal inputs and redundant power supplies ensure the display will continue to function in the unlikely event of an LED unit power failure. Dynamic power consumption features actively monitor image luminance and adjust power output accordingly to optimise power consumption and reduce operator eye-fatigue.
