19 Inch SAW LED LCD Open Frame Touch Screens

LBT-1904OTEAS | 19 Inch LED SAW Serial Open Frame Touchscreen Monitor

LBT-1904OTEASU | 19 Inch LED SAW USB Open Frame Touchscreen Monitor

The largest 4:3 aspect industrial touch monitor that Caltron carries is the 19” surface acoustic wave (SAW) touch screen LED open frame monitor.  This particular touch screen monitor comes in two model types and is distinguish by the following:  LBT-1904OTEAS to represent the touch monitor with a serial touch interface option and the LBT-1904OTEASU to represent the touch monitor with a USB touch interface option.

Why is Caltron’s LBT-1904OTEAS useful in industrial applications?  This 19” touch screen monitor is comprised of all industrial grade components, from the internal boards, LCD panel to the chassis that holds all of the parts together.  With all industrial grade components, the unit as a whole is equipped to handle many various harsh environments and is capable of dealing with extreme temperatures when put to the test.  How do I know if this unit will not have a design change, if there is an LCD panel revision?  Caltron’s engineers have designed the chassis to remain consistent throughout the lifetime of the monitor and will make any necessary modifications to ensure that the LCD panel will remain in the exact same position, so that designers and integrators will not have to worry about any potential redesign changes to their enclosure if there is a need to replace the 19” SAW touch screen open frame LED monitor in the future.

A substantial difference between an LED backlit touch screen monitor and a CCFL backlit monitor would be the brightness.  The 19” SAW touch screen LED monitor is rated at 350 nits brightness, which is about 100 nits brighter than a typical CCFL touch screen monitor.  This added brightness provides more versatility for the touch screen monitor and the open frame becomes more equipped to handle brighter environments with more ambient lighting.  This monitor is equipped to handle both industrial and commercial applications that need to integrate a 19” open frame touch screen.  This touch monitor is great for applications that require a larger than typical screen size.
