Features and benefits of RM-UX20 industrial LCD monitor for rack mount, swivel-arm mount, VESA mount, panel mount.

RM-UX20 industrial LCD monitors is constructed of heavy duty metal for ruggedness. The rack mount LCD monitor is suitable for rack-mount, VESA mount, swivel arm mount, panel mount. Ruggedized for industrial environment, the industrial LCD monitor has a 20 inch LCD, 700:1 contrast ratio, wide viewing angles, and UXGA 1600 x 1200 optimum resolution. It includes a built-in A/D (analog/digital) conversion board for interfacing to standard analog video cards. A DVI interface provides even sharper and clearer images. Front bezel OSD control buttons let you adjust the display for optimum viewing.

Features and Benefits
20" screen size @ UXGA resolution
An LCD with 20 " screen size is approximately equivalent to a 21"~22" CRT monitor in effective display area. UXGA resolution equals to 1600 x 1200 number of pixels. With almost 2 million pixels, the increased screen resolution has a direct impact on productivity, because now you can show more of your data, images, spreadsheet with less scrolling.
High contrast ratio display
With 700:1 contrast ratio, a level approaching that of CRT monitors, you can judge your work more accurately because subtle shades of color or gray in your graphic images become visible.
Ultra-wide viewing angle, 170 degrees both horizontally and vertically
An LCD, being a light valve, creates more collimated light, resulting in a narrow viewing angle compared to conventional CRT monitors. To give the display a wide viewing angle, it is necessary to apply enhancement films or create novel liquid-crystal structures that can evenly spread the light. To complicate matters further, viewing direction must also be considered. Most TFT LCDs have an asymmetrical viewing cone. These LCDs are optimized for a wide horizontal viewing angle and a narrow vertical viewing angle.

The RM-UX20, on the other hand, exhibits both wide and symmetrical viewing angles. What you get is a monitor that closely resembles a CRT in viewing angles while providing a sharper and more stable image. The wide viewing angles—170-degrees vertical and horizontal, means you see the entire image clearly, even from a steep angle.
Versatile mounting options
RM-UX20 can be rack mounted in standard 19" equipment racks. The front bezel is made of 0.25" thick, heavy duty aluminum with mounting holes (see outline drawing for dimensions). It can be wall-, bench top-, swing arm-mounted via rear panel's VESA  mounting holes. Both 75mm and 100mm mount patterns are supported.
Direct backlight LCD panel
Backlight systems for LCDs can be divided roughly into two types:
1. directly-under (reflective) systems, and
2. sidelight/edge light (light-guiding plate) types.

In the directly-under system a fluorescent lamp is positioned in a cage consisting of a reflective plate and diffusive plate, so that light from the lamp is reflected and scattered. Fluorescent lamp shapes in use include straight tubes, U-shaped and W-shaped lamps. A light curtain and a diffuser are mounted over the lamps to reduce unevenness in brightness. Compared with other methods, the directly under system offers higher brightness.

Sidelight/edge light uses a straight CCFL lamp along one side of the LCD, or two lamps on opposite sides of the LCD, or L-shaped lamps along the opposite corners of the LCD. Edge light units use a reflector and light-guiding plate to direct light from the fluorescent lamp to the screen to evenly disperse light over the LCD. LCD panels using this backlighting technique are usually thinner and have good average brightness. In addition, greater ease in changing the lamp, and lower power consumption are also important features.
