Rugged Industrial Displays

Rugged Monitors are commonly utilized in environments where standard commercial grade display monitors might not be able to survive. High quantities of dust, moisture, dirt, oil, and other liquid containments may be found in environments where rugged displays are necessary. Rugged LCD display monitors, such as those from Revosys, come in an ultra-compact enclosure, use anti-corrosive lightweight materials such as Aluminum 6063 and 7075 alloy that can withstand constant wear and tear. Most rugged monitors are NEMA 6 / IP67 / IP65 / IP66 compliant, which make them resistant to liquids, and dirt.  Such rugged display monitors may have to sustain operations in extreme temperature environments of up to -40C to +70C, thus care must be taken to ensure that the internal electronics can support a wide temperature range. Support for higher temperatures is critical when the environment is under direct sunlight for extended periods of time.

Sunlight readability is a common key requirement for the users of rugged display monitors. Users often have to use rugged display monitors within or alongside equipment that takes its daily toll of direct sunlight. Sunlight Readability is achieved once a contrast ratio of 5:1 or higher is reached in the sunlight. This is achieved by using a high power LED backlight in combination with Anti-Reflective coatings and Optical Bonding of the touchscreen.

Rugged display monitors are commonly used in automotive environments where a wide-input power supply range is absolutely critical to continuously supply stable voltage levels to protect the displays. It is critical that a rugged industrial display monitor is used in a vehicle environment with a rating of at least 6V and up to 36 volts or higher. Such a wide input voltage allows the industrial monitor to survive voltage spikes and dips upon engine cranking.

Rugged LCD Display monitors are made up of a IP67, IP66, or IP65 rated sealed design with sealed locking style cable connectors that ensure water resistance against directed water pressure and complete water submergence. These industrial monitors come with an array of versatile input options to provide an unprecedented variety of application possibilities. These input options include DVI, VGA, HDMI, and Composite Video, as well as touchscreen inputs of RS232 or USB. Revosys manufactures rugged industrial monitors in various combinations including sunlight readable monitors, IP67/66 rated displays, and touchscreen interactive displays.

Rugged display monitors are effective against vibrations and shocks, making them a good candidate for use in industrial, aerospace and marine display equipment. The rugged monitors can also be used with an internal or external dimmer to control the luminance daytime high brightness as well as nighttime low-light applications.

Revosys is a USA manufacturer of rugged display monitors for industrial and commercial uses.

Industrial Medical Device LCD Display Monitors

Medical devices are the backbone of the modern Healthcare Industry worldwide. Critical patient information is shown for the facility staff from devices that measure heart signals, MRI and CAT Scans. LCD Displays are used nearly in every modern medical device for displaying information and allow interactivity for the patients. These devices typically consist of sensors, computer processors, communication gateways and an embedded Display Unit using an Open Frame Monitor or LCD Kit.

Medical devices commonly operate by using a Host PC with an embedded PC board that sends a VGA, HDMI, DisplayPort or DVI signal to an LCD panel through an AD Controller Board, at which time the signal is converted to TTL, RGB or LVDS which displays the image on the LCD Panel.

Modern Medical Display Monitors, such as those manufactured by Revosys, use digital signal processing which helps miniaturize the monitoring devices hence making them more portable. Unlike the older, CRT display units were mono-channeled showing only 1 color of information at a time, the LCD displays can show multiple vital signs on the same image, at the same time.

Medical devices require special LCD Displays that fulfill the strict requirements of the tasks. These LCD displays, such as those used for X-Ray or CT Scans, require a high level of precision. Only the highest quality of displays will suffice for this task. Displays for these applications require high color saturation (typically 1.02B colors), high color gamut (at least 72% or higher), and high contrast ratios. The higher image quality provides physicians and doctors with vital information that may not have been visible with lower-quality displays. Revosys provides a range of the highest color gamut displays (up to 92%), as well as colors and contrast ratios.

Displays used in a Hospital setting require a higher level of protection from the wear and tear of this environment. The IP65 displays that Revosys offers, help protect the LCD Display monitors from fluids, and dust that could potentially ruin the electronics of a less-protected display. Anti-Microbial coatings, also known as Anti-Germ coatings for LCD displays are offered by Revosys to nearly eliminate the germ content that is found on the surface of typical touchscreen interactive display monitors.

Portable medical devices are generally fitted with displays such as a 7” multi-touch projected capacitive touchscreen monitor or an 8.4” industrial monitor. The 8.4” Open-Frame LCD Display has an aspect ratio of 4:3 and a resolution of 800×600. It features a contrast ratio of around 600:1, an efficient LED backlight and can be fitted with a variety of touchscreen technologies. The 450 nit LED backlight brightness of the 8.4” LCD display monitor provides for viewing in bright indoor conditions. These display monitors can be coated with an AR (Anti-Reflective), AG (Anti-Glare), and an AFP (Anti-Fingerprint/Oleophobic) coating to make them even more effective for the application.

Gaming & Casino Machine Industrial Display Monitors

In this article we will have a look at how Industrial LCD Display Monitors can serve Gaming Machine requirements, as well as selecting a display, be it for Casino games, Recreational Bowling, Score Keeping, Arcade, or Point-of-Sale Counters.

1.    LCD Size Considerations

Buying the largest possible LCD display monitor to attract attention of the users’ may not be an ideal solution. If you’re looking for an Industrial Monitor for Arcade machines, assuming that a user is 3 feet away from the display, a 19” Industrial Display Monitor that is high brightness and high contrast may be sufficient. It benefits to seek a display with high contrast, and adequate brightness. Indoor applications with low levels of surrounding light may only require an LCD display with 350 nits for sufficient brightness. However, environments that have high ambient light would require at least 400-500 nits brightness at a minimum for optimal viewing.

Besides the contrast and brightness levels, it is important that a high native resolution is used if the user is viewing the LCD display from a short distance. Higher resolution displays will enhance the viewing experience as there is a much greater level of detail in the image. At a further distance, the native resolution is less important, as to the naked eye the individual pixels seem to smooth-out.

2.    Check the Features

With such a wide selection of Industrial Monitors, it is important to assess the requirements for the application. Select a vendor that can provide you with a modular display solution which can be easily adjusted to match your requirements. The application may not require audio speakers, but it may require a DVI input. A monitor with a modular design will allow a technician to upgrade or easily replace parts inside the Industrial Monitor right in the field.

Features such as ultra wide viewing angles may not be required for gaming displays at close-range. However, high response rates for gaming applications may be a necessity.  General Industrial Monitors that use traditional TN type LCD displays may have adequate response times, but significantly limited viewing angles as well as a low color gamut.

3.    Beyond Picture Quality

Gaming or Casino Machine Display Monitors must be chosen with the quality of the image in mind, as well as installation method, touchscreen options, drivers support, and video signal input options.

For the installation method, care must be taken when selecting the monitor to ensure that the a versatile mounting bracket(s) are provided for installing inside of Gaming, Casino or Point of Sale Machines or attaching to flat surfaces such as walls. The Revosys Industrial Monitors come with mounting brackets that allow the whole display to be mounted either via top and bottom fixtures, or via the left and right sides. Optionally, if installing the Industrial Monitors onto a wall, Revosys provides VESA mounting holes on the rear cover of each display.

Just as important as the installation method, are the available options for the inputs from the host PC. No longer are Industrial Monitors only limited to VGA input. Revosys provides VGA , DVI, HDMI and DisplayPort (Coming Soon) connectivity for their Industrial Monitors to fit the requirements of the latest gaming machines. Digital Inputs, such as DVI & HDMI and DisplayPort input provide a loss-less digital connection between the graphics card in the Gaming Machine (Host PC), and the Industrial Monitor outfitted with an interactive touchscreen.

The touchscreen is a vital component of any interactive Gaming or Casino Machine. Revosys suggests the use of Surface Capacitive touchscreens for single-touch applications, and Projected Capacitive touchscreens for multi-touch gaming applications.

Industrial Monitors from Revosys are offer lightweight & space-saving design, power efficiency and cost effective-ness, all while offering a wide-range of options and an easy installation method. Revosys also provides embedded Panel PCs within their Industrial Monitors as well as fully integrated LCD kits that can be ideal for fully custom installations.

Sunlight Readable Monitor Displays

The Sunlight Readability of an Industrial Monitor Display is determined by the difference between the external ambient light and the display’s internal illumination (backlight brightness). Illumination is a measure of energy expressed in Cd/m2. The surface of the LCD must emit or reflect enough light to match the illumination of the sunlight or external light sources, for the display to be sunlight readable. There are several ways to accomplish this task, with the ideal solution being a combination of all the available options.

Directly increasing the LCD displays’ internal brightness, by replacing the LED backlight to a higher output version, is one way to overcome the illumination of the sunlight. The increase in the number of LEDs used to achieve this often results in lowered energy efficiency, potentially higher heat generation, and possibly increased LCD dimensions.

A less common, but more efficient way to achieve a similar result as increasing the LCD’s backlight is by using Transflective technology. Transflective monitors display technology allows illumination reflection without the need to increase the internal backlight. This reflective function captures and reflects the ambient light passing through the LCD TFT pixels that allows the LCD to glow brighter, making it viewable under a whole range of ambient conditions. However, transflective LCDs are often known for narrow viewing angles, low indoor brightness, discoloration and the gradual loss of contrast ratio. In terms of their cost, practicality, illumination vs lumination ratios and application choices, these LCDs are not always well suited for industrial uses.

The third option for achieving Sunlight Readability is known as Optical Bonding technology, which typically costs higher than the aforementioned types. With this technology, the internal glass is optically coupled with the front glass (such as a touchscreen) with a minimal gap between the two. The distance reduces Newton rings (the rainbow effect caused by non-uniform cell thickness).  To increase display image quality, a standard display is coated with an enhancement film to improve brightness and contrast and an Anti-Reflective film or coating is applied to both sides of the touchscreen to significantly reduce light reflection. The touchscreen can be treated with Anti-glare, Anti-Reflective and even Anti-Fingerprint surface coatings. The Anti-Reflective layer helps to eliminate reflections, down to 0.3%, and maximizes image transmittance. The Anti-glare coating on the other hand, softens the visibility of the LCD’s direct light source. Revosys offers Sunlight Readable Touchscreen Industrial Monitor Displays with optional Anti-Fingerprint coating to reduce smudges and oil-marks left on the touchscreen surface.

Revosys uses active High Brightness Sunlight Readable LCD Display Monitors for use in high ambience environments. These enhanced LCD Displays offer a brightness of up to 1500 cd/m2, with a contrast ratio of up to 21:1. These sunlight readable monitors outperform all standard LCD Displays available in the market. Revosys uses enhanced LED backlights to create effective bright displays with the lowest power consumption and heat emission.

Surface Coatings for Display Monitors: Anti-Glare and Anti-Reflective

Optical Coatings are a highly-demanded feature for consumer and industrial equipment such as Industrial Monitors for Kiosks, Medical, Automotive, Aerospace, and Gaming. Optical surface coatings help increase an LCD Display’s durability, reduce glare, and diffuse or eliminate reflections. The undesired reflections lower the LCDs brightness, making an optical coating necessary to achieve sunlight readable brightness levels.

There are various types of LCD display surface coatings available in the market including Hydrophilic (Anti-Fog) coatings, Hard Coatings, VAR (Vacuum-Deposited-Specular Anti-Reflective coatings, Transparent and Dichroic Conductive), Anti-Glare coatings (Diffusion Anti-Reflection Hard Coatings) and finally, Hydrophobic coatings, better known as Anti-Smudge and Anti-Fingerprint coatings. Not every coating type is compatible with each other, and thus may not be used together on a single surface.

In this article we will examine the differences between two popular coatings that are often confused for each other – the Anti-Glare and Anti-Reflective surface coatings. Although both types help you improve your LCD display’s viewing and readability, their unique working mechanisms are quite different.

LCD Monitors and Displays Anti-Reflective Coating

“Anti-1.” Drawing. Winmate 30th October 2012

Anti-glare coatings ward off external sources of reflection, like bright ambience or the sunlight by using a diffusion mechanism that breaks the coherence of the incoming light off at the surface making the reflections invisible to the eye. This process however, damages the resolution and the clarity of the display unless the surface is chemically or mechanically textured (‘etching’ process) and the coating uses suspended particles. Although this process is much cheaper than most other coating solutions, the overall tradeoff in the display quality and vividness is often too huge a price to pay. Some anti-glare coatings, such as ‘Anti-Glare Hard Coating’ offer a better result at a slightly higher price.

The Anti-Reflection coatings, such as the ones commonly used in sunlight readable monitors help eradicate both sources of reflection – internal and external. In any display, reflection starts occurring whenever the light passes through any medium, be it from the solid (such as the glass touchscreen) to another solid or through air. The index of reflection between these surfaces crates phase differences and increases the refraction of light. The reflections accumulate and blur the LCD display image unless a high brightness LCD backlight is used.

Anti-reflection coatings work by bending and guiding the light as it passes through each medium, thereby reducing reflections across the visible spectrum and thus increasing the image transmission to over 99.5%. It also increases the display’s durability against scratches and smudging.
