KME Announces New Specifications for its 29LS121 Series of OEM TFT Chassis Monitors...

The range now includes a PAL Video option in addition to their VGA/SVGA capabilities. This enables the input of two video signals simultaneously - a PAL video source (e.g. from a Camera or VCR) plus a graphics signal from a PC or industrial PLC source. The monitor can be set to switch automatically between the sources on a Priority basis. e.g. always showing SVGA if no PAL is present. No separate graphics boards are required as the TFT monitor operates in the same way as a CRT monitor, accepting the same inputs.

High brightness TFT panels from Sharp or Toshiba are mounted in a robust metal chassis together with U.K.- manufactured Analogue to Digital converter boards. A metal EMC shield encloses the front of the chassis so that the complete assembly is capable of carrying the CE mark, relieving the end customer of Approvals concerns. The EMC shield’s position is adjustable so that a touch screen can be recessed in to the chassis, keeping the surface of the touch screen level with the chassis body. This assists easy integration of the monitor on to the customer’s equipment. The monitors come with pre-drilled mounting plates at the top and bottom of the chassis case. These plates can be customised for differing applications.

Depending on the application, the 29LS121 series are offered with either On-Screen-Displays for set up of the images or with simplified Set-and-Forget controls for installation personnel only.The monitors operate from 110/230Vac and 24Vdc and are designed for a variety of industrial and military applications including factory automation, process control, measurement and inspection equipment.

12.1" is a popular size of Flat-panel monitor for industrial use. The display area is equivalent to that of a 15" CRT but KME’s 29LS121 series has dimensions of only 329 x 236mm and a depth of only 54mm. The 12.1" TFT panel is of SVGA resolution (800 x 600 pixels) The lower resolution PAL input is automatically processed by the A/D board to fill the full display area. The VGA (640 x 480 pixels) input is subjected to a Pixel-Optimisation process to give excellent readability when it is expanded to fill the SVGA panel. In fact the VGA display is so good that KME has attracted customers, who cannot upgrade from existing VGA software, wishing to replace 12" CRT VGA monitors with 12.1" Flat Panels. (the 12" CRT is no longer readily available).
