Description
The CPX1-241 is a rugged military grade and industrial grade high performance 9U mount-on-rack LCD panel
display offering 24-inch TFT LCD display with LED backlight. The display includes a bonded anti-reflective glass
cover with an optional bonded mesh EMI filter and an Infrared dual-touch touch screen.
The CPX1-241 family is designed to meet Mil-S-901D and MIL-STD-810G and includes solid and lightweight
5052-H32 aluminum construction and locking stainless hardware throughout. As a 24-inch display is wider than
19-inches, the display mounts in front of the rack and mounting brackets can be specified for racks with different
front-to-rack-rail spacing.
The 24-inch display offers 1920 x 1200 native resolution, LED backlighting, 300nit brightness, 1000:1 native
contrast (before installing the AR filter), and 89 degree viewing angle. The Pixel Pitch for the 24-inch display is
.270 x .270mm. The display offers 16.7 million colors (True Color).
The display is equipped standard with a bonded glass overlay with a DARO oleophobic anti-reflective (AR)
coating. This AR coating minimizes finger prints and repels dirt, moisture, and other contaminates to improve
image clarity. The coating is highly resistant to abrasion and is easily cleaned.
An optional embedded mesh EMI filter in front of the display is available for compliance with military EMI
standards. The glass is optically bonded to the front of the display with optically clear index matched adhesive
for superior viewing and ruggedness. A 6mm copper bus bar around the entire glass stack-up provides effective
EMI grounding. The contrast is significantly enhanced with this Anti Reflective glass stack-up in high bright
environments.
An optional infrared dual-touch touch screen is available. Infrared touch screen technology offers a multitude of
advantages over traditional capacitive or resistive touch screens. The IR touch screen can be used with bare
fingers, gloves or any other pointer. Multi-touch control is supported for gesture recognition, etc. Touch
activations is unlimited and there is no concern with damage to the touch surface. One compelling advantage to
IR Touch is the ability to install the anti-reflective coated glass bonded to the display for high-bright
environments. Another prime benefit of IR Touch is that this is a passive technology with no emitted EMI.
The CPX1-241 provides a high quality advanced scaling controller with a Genesis chipset. The rugged LCD
controller offers inputs for virtually any video signal including aRGB, DVI-D, HDMI, and optional video
(NTSC/PAL/SECAM, Composite, S-video, SD (YCbCr) and HD (YPbPr) component). An optional HD-SDI
adapter is available for professional and broadcast video applications. This is a specifically ruggedized
controller offering as standard conformal coating with high shock/vibration and temperature extreme tolerances.
The LCD supports full screen image expansion, on-screen PIP (Picture in Picture), Picture by Picture, and image
marker. Rounding out the display features is an optional infrared control and serial or Ethernet command port
including on-screen text overlay generation.
Included standard is a built-in 2 watt stereo amplifier and two speakers. The speakers are located at the bottom
of the front bezel of the display.
The CPX1-241 is primarily designed for rugged Military applications but can be used in Industrial, Commercial,
or Broadcast applications where reliability, quality and long program life availability preclude the use of cheaply
made imported units.
As with all Chassis Plans products, a wide variety of custom options can be configured per customer or
application specific requirements. Contact your Sales Engineer to discuss your particular requirements.
