RM-SX19 Industrial LCD Display
This item is no longer available.
- Features and Benefits
- 19" screen size @ SXGA resolution
- An LCD with 19" screen size is approximately equivalent to a 20"~21" CRT monitor in effective display area. SXGA resolution equals to 1280 x 1024 number of pixels. With more than 1.3 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-SX19, 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-SX19 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.
