Quadruple Rack Monitor containing OLEDs

OCM 404 W HD

Today Tamuz announced the world’s first OLED powered quadruple rack monitor to display SD, HD and graphic signals. The new OCM 404 W HD is mechanically a very compact device equipped with four 4.3 " (11 cm) wide screen OLED displays. With dimensions of only two rack units and a depth of approximately 2“ (48 mm) this monitor was constructed for the first time to house the OLED's within a monitor bridge.

Self-light-emitting displays have quite a number of advantages opposite to the common LCD technology, but till today these advantages are accompanied by higher costs.

The acronym „OLED“ stands for Organic Light Emitting Diode which describes generally displays that are comprised of organic materials that emit coloured light when stimulated by a low level voltage. Single cells (pixels) that are extremely small are built up as a cluster from red, green and blue light-emitting diodes on a carrier material. Configured in large numbers, such a display will generate almost every light colour possible while simultaneously emitting a high brightness consequently making OLED panels very well suited as video screens.

Fundamental advantages of the OLED technology versus LCD

* High brightness at extremely high contrast (>100.000:1)
* Perfect and true black, no light emitted when voltage is at zero
* Wide colour space to fit BT.R709, EBU, SMPTE or Adobe
* No viewing angle problematic at all
* Negligible response times (On-off switching the cells)
* Faster representation of video signals
* No backlight required
* Energy efficient operation
* Wider temperature range of operation
* Light weight and formable device

Signals up to 3 Gbit/s accepted

Each of the four displays in the OCM 404 W HD has a resolution of 480x272 RGB pixels combined with a newly developed interface for analog and digital video signals. Every display section has a traditional analog composite input, as well as a SDI input, which accepts signals up to 3 Gbit/s in the format 1080p60/50, and a VGA input accepting computer signals up to SVGA resolution. The video inputs have loop-through functionality and are built as 75 ohms BNC sockets.

Lifetime is more than 30.000 hours

The OCM 404 W HD is powered by an external 12V DC power supply. The power consumption of 36W nominal is extremely economical. OLED's consume power in a different fashion than that of LCD monitors. Its power requirements relate to the displayed video signal. A black screen needs no energy, as more white is present the energy requirement increases.

Early critics of OLED technology cited the probable lifetime of operation. Today, this is out of discussion. The expected lifetime for a 4.3“ display is more than 30.000 hours - three times longer as that of competitive LCD technology used in rack monitors. Therefore, the longer life of OLED panels offset by far the higher costs associated with an OLEDpurchase.

Wide screen displays, future proved 3G-SDI inputs, 1080p60/50 format support and the most modern display technology make the TAMUZ OCM 404 W HD a highperformance monitor for the visualization of signal sources in all areas of the studio technology. The monitors are deliverable as of first quarter 2010 at a list price of3.990 EUR net ($5.778 US local market).
