The latest LCD options incorporate robust and interactive feature sets.
The XP-2401HD from CoolTouch Monitors is a promising option for ambient light conditions thanks to its published 450 nits of brightness and a 700:1 contrast ratio. As a standalone multiformat, multimedia monitor, the CoolTouch XP-2401HD includes two SD/HD-SDI inputs with one reclocked output, one DVI/VGA input (DVI+Gender 15-pin), three composite video (shared BNCs for S-Video/component RGB/YPbPr) inputs, and one stereo pair of analog audio connectors. The de-embedded audio input feeds the built-in loudspeakers that can be used as a confidence monitor, and its unique tabletop stand allows the XP-2401HD to tilt up to 60 degrees.
Offering one of the thinnest monitors for lobby display installations, JVC unveiled its GD-32X1 32in. super-slim flatpanel HD monitor at September’s DV Expo. JVC emphasizes an original LED edge-lighting system that delivers uniform brightness and light efficiency with a 178-degree viewing angle. It features full 1920x1080 resolution with a 4000:1 contrast ratio, and it provides 90 percent coverage of Adobe RGB’s wide color space. The display’s high-speed Intelligent Gamma Adjustment is designed to improve contrast, particularly in scenes with light and dark areas. The Intelligent Color Management picture engine analyzes color distribution in each frame of the input signal in realtime for precise processing that results in images with more realistic colors and textures, according to JVC. Its larger brother, the GD-42X1, is a wide-gamut 42in. LCD monitor that features a 50,000:1 dynamic contrast ratio, a 12-bit per color processor (giving you 36-bit over RGB), and 52 manual picture adjustment properties.
LG Electronics has a diverse product line to engage lobby audiences and communicate messages with touch, stretch, and Triple View monitors such as its 47in. M4714T-BA wayfinding touchscreen that allows patrons to pick and choose their destination or identify their current location thanks to built-in 3M Dispersive Signal Touch (DST) integrated technology. The narrow 36mm bezel ensures that the LCD display fits seamlessly into any environment in either portrait or landscape mode. In addition, LG’s M4714V Triple View LCD monitor delivers a revolution in digital signage since the monitor connects customers with up to three different images or advertisements based upon their angle of view to the monitor. Using a parallax barrier, the light passage of the left, right, and center pixels is divided, allowing the M4714V to display three different images, each covering approximately a 50-degree viewing angle. Finally, LG’s sleek 720p 42in. class and full HD 1080p 47in. LCD monitors (models M4212C-BA and M4714C-BA) offer display options in portrait and landscape modes and split zoom capabilities for videowall applications up to a maximum of 5x5.
NEC claims its 46in. MultiSync X461UN is going to revolutionize the way LCD videowalls are perceived because its ultranarrow bezel allows for a screen-to-screen distance of only 7.3mm. The X461UN can be deployed in videowall matrices of up to 10x10 (100 displays), creating a total surface area of approximately 645 square feet. It offers brightness of 700cd/m2 and typical contrast ratio of 3000:1 while putting out a 1360x768 WXGA native resolution in true 16:9 aspect ratio. The display features Ethernet monitor and control, a commercial-grade sealed panel, an advanced cooling system for 24/7 operation, and a multilevel programmable zoom. For areas with lots of ambient light, NEC offers its 46in. MultiSync X461HB that shines out 1500 candelas, which is 130 percent brighter than NEC’s previous generation display, yet consumes only 37 percent more power. An optional Windows XP Pro single-board computer processes digital signage content and eliminates the need for an external PC, cabling, mounting, and power supply.
