The Panasonic TH-55LFV50 is a 55in. LED-backlit LCD screen with 800cd/m2 brightness and an automatic cooling fan suited for 24-hour operation. The system delivers 1920x1080 resolution while offering serial, LAN (web browser) and IR control, and an external stereo speaker output. Inputs include HDMI, DVI-D (in/out), composite, component, and VGA. The 0.14in. bezel width makes it especially suitable for videowall applications. The normal power consumption of 320W drops to 0.5W in standby mode.
Another great videowall display is the PS5580 from Planar with its edge-lit LED backlight technology, 400-nit brightness and the capability to scale up to a 10x10 array. The 55in. unit can be fitted with an optional mounting system for tiling and slim mounting depth. It can accept DisplayPort, HDMI (two), VGA, and DVI video with control capability on RS-232, LAN, IR, and keypad. Running on 130W, the screen produces a brightness of 400cd/m² and the monitor weighs in at 46lbs.
Prysm has released its next-generation Laser Phosphor Display (LPT) products with the debut of the TD2 Tile. The 25in. diagonal, zero-bezel unit has a standard resolution of 320x240 while the enhanced mode provides 427x320. The LPT display uses an ultraviolet, solid-state laser scanning the surface of the screen to excite the phosphor array and create the image. Prysm LPD videowalls can scale to sizes more than 100ft. wide while maintaining image uniformity over the entire display area.
The smallest media player from Rise Display has an Intel Dual Core processor, 4GB RAM, and a 32GB solid-state drive. The Preconfigured Media Player already has the Rise Vision Player in it so all that is needed to get it going is to enter a display ID. The standard operating system is Linux (Ubuntu), but Windows 7 can be installed as an option. In addition to its Ethernet port, the player has three USB 2.0 ports and two HDMI connectors.
For all-weather indoor or outdoor digital signage displays, Samsung has a solution in the OL46B large-format display with its 1,500cd/m² brightness and water/dust-proof design. The 46in. diagonal display provides 1920x1080 resolution, and it can connect to RGB, DVI-D, or DisplayPort video. Its internal speakers allow audio content to be heard in outdoor environments, and the Smart Scheduling feature automatically selects on/off, input source, and volume level on a date and time plan.
The PN-E802 high-definition, LED-backlit LCD display from Sharp shows its 1920x1080 resolution over an 80in. screen with 450cd/m2 brightness while projecting sound from its 7W per channel stereo audio system. Designed for continuous 24/7 operation in portrait or landscape orientations, the monitor has a fanless architecture, and it can be fitted with an optional interface board to add a LAN port and expand its selection of input signal formats. The unit comes standard with RS-232 serial control port, VGA, and HDMI video inputs.
While the displays are getting bigger, media players have shrunk while adding features. As an example, Shuttle designed the DS47 fanless media player with dual gigabit LAN interfaces, RS-232/422/485 control, USB 2.0 and 3.0 ports, and dual video outputs with HDMI and DVI. With a body thickness of less than 40mm, the player uses only 65W power, fits a VESA mount, and operates quietly. It is equipped with an Intel high-performance Celeron Dual Core processor and built for 24/7 operation.
