Industries have started to transition to the realm of advanced automation and edge applications with the introduction of AI and industrial automation. To maintain their continuing operations, industries need a middleman between the operators and automated machinery. Rugged display monitors can therefore be employed as interactive solutions that effectively handle various functions and sequential duties in order to accomplish a methodical process.We hope to provide you with more insight into rugged LCD displays and their potential impact on edge applications and industry 4.0 in this blog.
The light-modulating qualities of liquid crystals and polarizers are used in LCD (Liquid Crystal Display) technology.Industrial LCD monitors are tough computer displays that use LCD technology as an interface when connected to a machine or computer. Furthermore, the toughest industrial deployments are precisely and meticulously engineered to be withstood by rugged LCD monitors, all while preserving their dependability, endurance, and durability.
The typical LCD monitor is not the same as the industrial tough LCD monitor. The maximum brightness that an LCD standard monitor can provide is 350 nits, which is insufficient for outdoor use. When placed in direct sunshine, the robust LCD monitor's brightness may reach up to 1000 nits, which greatly improves readability. This has led to the widespread usage of this technology in even more hostile settings like mining, as well as in retail displays, intelligent transportation, and outdoor kiosks.
The HMI deployment for industrial control systems uses robust LCD monitors as a cooperative solution to effectively manage ongoing tasks and handle numerous operations.The display interface known as an HMI, or human machine interface, gives industrial operators the power to select and ascertain a pre-planned outcome from the machine and applications. These results are typically comprised of an intricate web of sensors, alerts, and on/off features. An industrial operation's productivity and operational efficiency will increase with a properly configured HMI system. Scratch-resistant glass, anti-glare technology, optical bonding, and other features make a robust LCD monitor an essential tool for providing users and operators with a dependable, efficient experience, particularly in demanding industrial settings.
For field operators to be informed and ensured of all operation processes, a robust display monitor is essential.For example, industrial LCD displays make it simple for the operator to identify any harmful system fault and maintain smooth operations. To withstand the most demanding industrial deployments, enterprises must ensure that the display monitor they utilise is dependable, robust, and adaptable.As a result, robust display LCD monitors have many advantages, including:
A ruggedized LCD display usually indicates that it is fanless.Fanless designs use heatsinks and heat pipes in place of thermoelectric fans (TECs) to cool down the internal heat-generating components. The system's increased longevity, dependability, and durability are made possible by the removal of the fans. Here, the absence of ventilation holes needed for active fan cooling allows fanless designs to avoid the ingress of dust and water particles endangering the computer's components. Additionally, a fanless design efficiently regulates the computer's temperature by using heat pipes and a heatsink composed of ultra-conductive materials like copper and aluminium.
An industrial LCD monitor's IP (Ingress Protection) certification indicates how resistant it is to water and dust. As a result, a tough industrial monitor with an IP rating helps to guarantee endurance and durability when exposed to volatile situations.The IP rating of a display monitor typically falls between IP65 and IP69K. The solid ingress protection against minute dust particles is shown by the first digit, which has the highest rating of 6. Water immersion and strong, hot water jets are protected against by the second digit, which has the maximum grade of 9K. In automated lines, where hygienic washdowns with high-pressure, high-temperature water jets and cleaning agents are frequently used, an IP rating is essential.
An LCD screen that is resistant to weathering makes it possible to use the PCs in both indoor and outdoor industrial environments.Since the LCD monitor uses liquid crystal display technology, freezing weather might be harmful to it. Because of this, it is essential to make sure the LCD monitor is safe to use in both freezing and extremely hot conditions.For instance, Kelai's tough industrial LCD monitors are designed to function in a variety of weather situations and temperatures, from -20°C to 60°C, all the while preserving dependability, lifespan, and durability.
It may not be good for a robust LCD monitor to be mounted on a moving car that is frequently shaken and jostled. As a result of its ability to achieve fanless architecture, minimise moving parts, and withstand 20G of shock and 1.5 Grms of vibration at 5-500 Hz, our panel mount LCD monitor has undergone extensive testing and validation. Consequently, these ruggedized LCD monitors have demonstrated their dependability and longevity in the harshest industrial settings.
An industrial display monitor that is tough is designed to handle a variety of jobs and continuous operations. To support expansion and meet demand, it needs a wide variety of I/O ports. As a result, a variety of I/O ports, including USB, VGA, Display Port, SIM, antenna hole, DIO, serial ports, and M12 connectors, are included with robust LCD monitors. Delivering adaptable and flexible features for various industrial workloads requires I/O flexibility.
The likelihood of coming into contact with voltage fluctuations increases when an industrial display monitor is mounted onto a machine or system. In order to prevent power inputs that spike above 50V, the ruggedized display monitor has a wide range of power input, ranging from 9-50VDC, Over Current Protection (OCP), and Over Voltage Protection (OVP). Consequently, industrial robust LCD monitors avoid downtime and shield the motherboard from overvoltage burn.
High-response touchscreens on rugged LCD monitors enable improved operator-automated machine interaction quality. Furthermore, a touch LCD monitor offers two options, such as capacitive and resistive touch.
1. LCD Monitor with Resistive Touch
There are multiple tiny layers that make up a resistive touchscreen display monitor. In order for the display to perceive pressure and record input, pressure must be applied to the outer layer before it can be pushed onto the next layer.Resistive touch permits input objects, such as fingers, fingernails, stylus, or gloves. On the resistive touchscreen LCD, Kelai applies extra PET film (polyester film) to improve lifetime, dependability, and durability. PET film is a transparent thermoplastic that performs well and has a better tensile strength, UV resistance, and minimal moisture absorption. Ten million keystrokes have been used to test and certify the Kelai PET film touchscreen LCD monitor's ability to pass the knock test. Because of this, heavy industry sectors including mining, heavy haulage, and agricultural favour resistive touchscreen technology over capacitive.
2. LCD Monitor with Capacitive Touch
Electrical conductivity is used by a capacitive touchscreen display monitor to detect input rather than pressure.Capacitive touchscreens are able to detect conductive objects, such conductive gloves or a fingertip. Conductivity-based touch detection improves sensitivity and responsiveness by registering up to 10 touch locations and movements. This gives users additional options based on various industrial applications, such as pinch, zoom, and multi-touch. High sensitivity touchscreens are necessary for improved end-user experiences in industrial applications like kiosks and retail, where capacitive touchscreens have been widely deployed.
An additional thin resin layer is applied using optical bonding technology between the TFT LCD layers and the glass or touchscreen. The glass and TFT layers are bonded together to remove any air gaps between them by the resin layer, which is a plastic layer that has been moulded using a liquid synthetic resin. This technique thus provides further protection appropriate for heavy industry, transportation, medical, and military uses. There are various advantages to this technology, including:
1. High optical clarity and sunshine readability: The resin layer, which prevents light from passing through below the screen's surface, minimises refractions on the screen, making it easier to see and read, especially in direct sunlight.
2. LCD Protection: The stronger LCD monitor can withstand greater shock and vibration thanks to the resin layer in optical bonding, which also lengthens the display's lifespan and dependability.
3. Protection Against Dust and Liquid Ingress: Optical bonding physically prevents liquid and dust particles from penetrating the spaces between the layers of the screen. Furthermore, condensation-related moisture may remain inside the opening for an extended period of time, resulting in hazy pictures and even irreversible harm.
4. Improve Touch Accuracy: By preventing touch deviation brought on by an air gap, the resin layer inside the gap keeps the substrate's pressure constant.
Different mounting options are available for industrial LCD displays to best suit a variety of industrial applications. The display monitor's mounting choices increase its ergonomics, versatility, and flexibility during deployments by enabling it to operate in a variety of orientations and arrangements. As a result, panel mount, VESA mount, and yoke mount LCD monitors are among the mounting possibilities.
