In contrast to consumer electronics, industrial monitor are designed for more than just optimal use indoors. From landscaping companies to construction sites, from agricultural activities to outdoor work environments such as freight transport, industrial displays provide convenient visibility to increase productivity and reduce eye strain.

So industrial displays are designed to improve durability and work with the rigors of industrial and commercial applications. They are available in a variety of sizes and resolutions, and have multiple mounting options as well as touchscreen and non-touchscreen options.

How to choose an industrial monitor?

When selecting an industrial monitor, it is important to consider the environment and application in which it will be used. Will your monitor come into contact with any liquids? Is it dusty? Does it need good brightness? The type of integration (rack mount, panel mount, etc.) is also important. Which touchscreen is right for your application and what level of protection do you need?

The following references are provided based on your work environment and planned application


The desired screen size and format. We define the diagonal (inches) and the width:height ratio. 6:9 and 4:3 ratios are most appropriate.

Resolution of the screen. Resolution refers to the level of detail in an image.

Brightness. This is the luminous intensity of the screen. If the screen is not bright enough, you will not be able to see anything in full sunlight. The standard brightness is about 250 cd/m²." A "sunlight readable" monitor can be used in very bright environments and the screen must be brighter than 1000cd/m2.

The resistance of a monitor is the ability of the screen to withstand damage in order to avoid short-circuiting or infiltrating your system.

Display integration and installation.

Touch or no touch.

Which technology should I choose for my industrial screen?


LCD (Liquid Crystal Display) screens use pixels with a backlight to get a standard image that lacks black density and grayscale, making the LCD screen quite large and heavy. LCD screens are very energy intensive, but have the advantage of being very affordable.

LED (light emitting diode) screens are very popular in the market, and the image is very precise and uniform. LED screens are illuminated by light emitting diodes, which allows for better image quality and uniformity. LED screens are more expensive than LCD screens, but they are still affordable.

OLED (organic light emitting diode) screens offer the best image quality on the market. This type of screen uses a chemical that glows when it comes in contact with an electric current. They provide unparalleled depth of field and color nuance. This type of screen is thinner, lighter, and uses less power than other technologies. On the other hand, they are much more expensive.

Plasma screens: Compared to LCD screens, plasma screens provide better image quality; better grayscale and black tones, and greater depth. The minimum size of a plasma screen is 107 cm, which makes them quite bulky. They also have higher energy consumption than LCD screens. Due to the older technology used, these screens are cheaper.

How to choose a touch screen?

There are two types of touch moniter / touch screen technology.


Resistive touchscreens: Two conductive layers are separated by an insulating layer. When the user touches one layer, the two conductive films come into contact, which causes an electric current to flow. A voltage is applied to the device and its coordinates on the screen are measured and transmitted to the system. This type of touchscreen is essential in many applications (GPS, video games, cash registers, electronic agendas, etc.), it responds to any form of pressure, and is potentially more accurate than capacitive touchscreens. It works when touched with a stylus, a gloved hand, a bare finger, a fingernail, and so on. In addition, this type of touchscreen is water, oil, and dust resistant. However, resistive touchscreens are more sensitive to scratches and other damage caused by sharp objects. It is also less responsive than capacitive touchscreens, and its responsiveness decreases over time. Finally, resistive touchscreens are less transparent, resulting in a 20 to 25% loss of screen brightness.


Capacitive Touch Screen: With this technology, a layer placed on the glass surface accumulates an electrical charge. When the user touches the layer with their finger, the charge is transferred to them, creating a measurable change in the layer (the electrostatic field is interrupted). The sensor then determines the coordinates of the affected area. For "multi-touch" applications, it is necessary to move to touchscreens that use projected capacitance technology. This technology can be used with thicker screens. This allows the touchscreen to be covered by a highly resistant armored glass screen. Capacitive screens have many advantages: they are rugged and scratch-resistant, and they are also brighter and more transparent than resistive screens (90% transparency instead of 75%). The screens are also more sensitive: you only need to touch the screen to get an immediate response. The disadvantage of capacitive technology is that it doesn't work when the user is wearing gloves.

What protection specifications should your industrial displays have?

The industrial monitor you choose must be best suited to your application, but it must also meet the protection standards applicable to your industry.


IP Rating: The first digit of the IP (Ingress Protection) rating indicates protection against solids, while the second digit indicates protection against water or other liquids. Industrial monitors are typically rated IP67 or IP65. lastly, you can choose "Full IP" (all sides are protected) or "Front" (only the front side is protected).

IK Rating: the 2-digit IK rating is an index of protection of electrical equipment against external mechanical impact. It indicates protection against impact energy and is expressed in Joules. It gives the energy equivalent to the fall of a certain weight of mass from a certain height. For example, IK01 => a material can withstand an impact energy of 0.15 Joules (the impact of a 150 gram mass falling from a height of 10 cm). an IK00 rating means that the device is not protected.

The ATEX standard is concerned with the protection of personnel working in environments that are sensitive to the risk of explosion. ATEX compliant industrial monitors are available for use in explosion-risk areas, distinguishing between areas with high concentrations of gases and vapors (Zones 0, 1, and 2) and areas with high concentrations of dust (Zones 20, 21, and 22).

MIL-STD-810G/F is a U.S. standard for ruggedness of equipment. The standard was developed for the U.S. military and is now used commercially to indicate how well a product is suited to environmental conditions.

Which connection method should I choose for my industrial display?

VGA Analog Interface: This is the most widely used video output interface, which is standard for industrial monitor. However, it can only provide analog signals and is not suitable for products with very high resolution.

VGA-DVI connector: This evolution of VGA can get analog and digital signals. Like the VGA, it has two screws that prevent the cable from being pulled out.

HDMI and DisplayPort: These are increasingly used in consumer products. They transmit all digital signals (audio and video) over a single cable. They can also transmit very high resolutions.

LVDS connector: This type of port should be favored for integrated screens. It connects the display to the graphics card through copper wires and allows high data rates.

S-video connector: Used for analog video signals, transmitting color and brightness respectively.

BNC connector: transmits video signals in analog mode, and also allows audio transmission. It can be used as an analog and digital connection, as an antenna connection or for electronic testing. It can also be used for thin Ethernet networks. It is used as an electrical connector at the end of coaxial cables, most commonly for RF.


Which type of stand should you choose for your industrial display?

When installing the monitor, you have the option of mounting it on a wall or stand, or integrating it into a complete system. The monitor has predefined holes and is configured according to the VESA mounting standard. The standard also defines the screws (M4, M6, or M8) to be used and their location.

Panel mounting: The monitor is designed to be embedded in kiosks, cabinets, dashboards, etc. The bracket is behind and therefore not visible. The stand is at the back and therefore not visible.

Rack Mount: The monitor is attached to the frame of a 19" rack from the front with four screws.

Flush mount: same as panel mount, but with visible fasteners.

Open Frame: The monitor has no housing or frame, but is surrounded by an exposed metal chassis to which all internal components are bolted. The advantage is that you can dress up and customize the profile or chassis to your liking.
