Obsolete CRT Monitor replacement
specialists!
KME has perfected the LCD-for-CRT Monitor replacement, allowing obsolete sized CRT screens to be replace with an LCD, interfaced with any legacy signal and giving a full-screen, crisp, bright display
CRT technology is under siege and falling out of favour as the ubiquitous flat-panel steadily gains market share Some CRT sizes are nearly impossible to source now that CRT manufacturers see an end to all but large, wide screen tubes for domestic TV

KME perfects LCD-for-CRT monitor replacement
CRT technology is under siege and falling out of favour as the ubiquitous flat-panel steadily gains market share: some CRT sizes are nearly impossible to source now. KME has the answer
CRT monitor replacement in LCD form,12 inch size
12 inch Cathode Ray Tubes were once the most popular size of colour CRT on the market and were used in a variety of Industrial and Military applications: a replacement monitor is now available
KME launches the Legacy Pixel Transformer!
KME introduces a revolutionary new product to solve worldwide Legacy Display problems - the Legacy Pixel Transformer, a deceptively simple metal box containing the result of years of experience
The 12" and 20" colour CRTs - so popular during the 1980/1990s - are examples of tubes no longer produced anywhere in the world.
This is not good news for OEMs and their customers in machine tool control, process control etc who are committed to support their CRT displays for several more operational years.
Many of these old displays were embedded in the control furniture (i.e in chassis monitor format) and substitution by a flat-panel presents many mechanical problems.
Also, the older the system, the more likely it is that the video signals to the monitor are not of modern VESA standards, making it impossible to achieve a display on a standard flat-panel monitor.
KME was formed 25 years ago to make CRT monitors.
Certain sizes are still in production but markets are changing rapidly to high resolution flat-panel LCD monitors and KME has a wide range of modern displays to meet this demand.
However, they have not forgotten their roots and have invested heavily in R and D to develop a range of LCD monitors that are specifically designed to interface with any legacy signal and give a full-screen, crisp, bright display.
The heart of this development project is a new LCD Analogue-Digital driver board (designated XP5) that forms the basis of their 51UN series.
Several mechanical formats are offered in screen sizes 8.4" to 21.3" including desktop, heads for ergo arms, rackmount and panelmount.
Special versions are available as complete look-alike CRT chassis with the same dimensions and mounting points (29LW series) and as mini-rackmount models designed to fit to the existing CRT chassis metalwork by utilising the CRT Lug fixing holes in the chassis (29LV series).
In addition to advanced processors to scale non-standard resolutions, the XP5 boards also incorporate circuitry to compensate for the low (and noisy) video and sync pulse levels found in Legacy installations.
The real breakthrough is that User set-up has been greatly simplified over previous models and KME is predicting an international market for its 51UN series.
