New 17.0" Yoke Mount - Ultra High Bright Series

The newly released Ultra High Bright Monitors are an ideal solution for indoor applications where high ambient light is a factor or throughout outdoor environments where direct or indirect sunlight can cause a less than optimum viewing experience. Dimming features allow images to remain crisp and clear as lighting conditions change. A versatile "yoke" mounting kit is provided for vehicle or shipboard mounting.

The powerful model VT170YHBU has a screen luminance level of 1200 cd/m2 nits as well as high contrast ratios and wide viewing angles.

For maximum versatility, the series is equipped with a multitude of video inputs, including HD15, DVI, NTSC/PAL and S-video.

Add-on options include:

• Optical bonding for DIRECT sunlight conditions and added structural support
• Resistive or Capacitive Touch Screen
• Integrated "heaters" for low operational temperatures down to -20C
• Manual Dimming or Automatic Dimming Sensor

VT150WKS Workstation With Integrated Computer

Many of today's real world environments require workstations that can survive in the most extreme conditions such as coal mines, rock quarries, oil rigs, chemical manufacturing plants, bakeries, and production floors of major food processing and packaging plants which require wash-down equipment. VarTech systems has met that challenge with the release of its enhanced product line of Industrial NEMA 4X (IP66) Workstations, equipped with an Industrial LCD Flat Panel, completely sealed keyboards and pointing devices as well as high performance pentium based computer systems. Optional video extenders (CAT5 or fiber optic) are available.

This new series meets the needs of many harsh environmental applications requiring NEMA 4x watertight and corrosive protection. Manufactured of 304 stainless steel (optional 316 available), these rugged workstations are equipped with features such as a Very Bright 450 nits Active Matrix TFT Display, multiple video input capabilities including HD15, RCA (NTSC/PAL), 5 Pin Mini Din (S-Video), and DVI, as well as extensive resolution capabilities. Optional touch screens can be integrated.

A multitude of mounting configurations are available: VESA Wall Mounting, Bulkhead, Pole or Pedestal Mount.

Notable Features
• Bright Active Matrix TFT Display • HD15(F), RCA (NTSC/PAL), 5 Pin Mini Din (S-Video) • 450 nits Brightness • VGA to SXGA Resolution • 110 / 220 VAC Power • Optional Touch Systems: Resistive and Capacitive • Optional Power Supply: 12VDC or 24VDC • Solid Stainless construction • Water tight Rox Gland for cable exit & entry Detailed Specs

Viewing Angles

Due to the emissive characteristics of phosphors located on the front face of the tube, off-angle viewing has never been an issue with CRT monitors as they naturally provide comfortable 180° views in every visible direction. This is not the case with LCD monitors, however, due to their inherent makeup. As light must pass through a series of materials prior to being emitted from the front face of the LCD, viewing angles can be narrowed, resulting in color shifts at the extremes and particularly in the vertical direction (up and down). LCD monitors have made vast improvements over the years in regards to their off-angle usability. As a point of reference, LCD viewing angle measurements are usually provided in a specification in both the horizontal (left and right) and vertical (up and down) direction.

There are two main ways that manufacturers can increase the viewing angles of their LCD products. One method involves the very design of the internal components of the monitor and requires the microscopic liquid crystals to be twisted in different ways (Fig. 1) so that light is emitted in different directions and in the widest angles possible. This method for improving viewing angles can be achieved by many types of technologies such as those generically referred to as inplane switching (IPS) or multi-vertical alignment (MVA), or by manufacturer-specific implementations such as NEC's XtraView® technology. These types of technologies generally deliver superior viewing angles in excess of 170° in both the horizontal and vertical planes.

Figure 1. In conventional LCD technology (top), liquid crystals stand on end, resulting in a loss of viewing angle. With wide-angle viewing technology (bottom), the crystals remain horizontal, which dramatically improves the viewing angle because the light passes through the crystals at their most efficient orientation.
