LBT-1904O | 19 Inch LED Industrial Open Frame Monitor

The largest industrial 4:3 aspect monitor size that Caltron carries is the LBT-1904O, 19 Inch LED open frame monitor.  Although the unit has a large display area, the unit itself, takes up relatively little space and leaves behind a smaller footprint than its counterpart desktop displays. 

Where can the LBT-1904O be used?  Since the 19” open frame monitor has a brightness of 350 nits from using an LED backlit panel, the screen is brighter than most can be used for indoor environments and some outdoor environments or places that have higher ambient lighting than most. 

Will the design ever change for industrial monitors?  Even with constant design changes and revisions to LCD panels, Caltron’s engineers will always ensure that the display area remains consistent without having to modify the mechanical dimensions of the overall unit chassis itself.  We ensure that the mechanical dimensions will remain consistent throughout the lifetime of the monitor.

With a larger screen size, the LBT-1904O, 19” LED open frame monitor is designed to be integrated into various applications such as Kiosks, instrumentation displays, control panels and other various industrial applications.
