Estone Panel PC and HMI Display Interfaces

Selecting Industrial Panel PC and HMI Display Interfaces

There are a number of key parameters that must be considered when implementing a LCD into an industrial panel PC or HMI (Human Machine Interfaces) design. They include size, resolution, brightness, touch control and display interfaces. The display interface that is used to connect to the panel PC embedded board is a critical factor in selecting a suitable display.

LCD Display Interfaces

Estone Panel PC Embedded Board LVDS Display Interface

For the past two decades, parallel RGB and serial LVDS (Low-Voltage Differential Signaling) have been the two major display interfaces in the industrial LCD applications. Most of the smaller displays, like those 3.5” 4.3” and 5” LCD touch panels or HMIs, use RGB parallel display interface. Larger displays, like 7”, 10”, 12”, 15”, 21” or larger for many of the industrial touch panel PCs, are connected with LVDS interface.

With the emerging of IoT (Internet of Things) systems with displays and interactive display systems, new generation display interfaces like eDP (Embedded DisplayPort) and MIPI (Mobile Industry Processor Interface) DSI (Display Serial Interface) are starting to make their way into the industrial panel PCs and HMIs. These interfaces have been specifically designed to be simplistic and cost-effective in industrial LCD applications and provide higher data bandwidth, scalability for large and small displays.

Solutions for Long Life Cycle Support

Another consideration of display interface selection is LCD display product life cycle. Many eDP or MIPI DSI interfaces displays in the market today are tied to the consumer markets like notebooks/tablets/smart phones and thus don’t support the long life cycle generally required by traditional industrial panel PCs and HMI applications. Solutions like eDP to LVDS, MIPI DSI to LVDS or RGB bridges are implemented to panel PC embedded boards to address the long life span product requirement.

The following are display interfaces supported by some of our panel PC embedded boards:

Rugged Tablet with Extremely Bright Screen and Digitizer Pen

Is a Rugged Tablet Right for Your Application?

Today’s consumer-grade tablets are impressive, but also often unequipped to meet the challenging demands of industrial applications. This leads to an increased need for rugged, utilitarian tablets. Industrial tablets are purpose-built and purpose-driven tools. Sectors where time and safety are essential benefit from these powerful and targeted pieces of equipment.

Once an organization decides to integrate industrial tablets into their workflow, it’s important to do your research and make an informed choice. If you think an industrial tablet may suit your brand’s individualized needs, you’ll need to find a model that aligns with your requirements.

Rugged Tablet Features

Ruggedized tablets are built with durability in mind. They’re also portable, allowing for quick and easy use anywhere necessary. The natural drops and shocks that come along with a demanding environment don’t pose the same risk to a rugged tablet as they would a consumer tablet.

Other notable features of tablets for industrial use include:

  • MIL-STD-810G standards
  • Customizable functions, such as adding different modules, RFID, CAC, and Fingerprint
  • Waterproof up to IP67
  • Optional accessories for specialized tasks
  • Remote monitoring and controls
  • Hot-Swappable Battery for Uninterrupted Battery Life
  • Sunlight Readable

Waterproof Options

Some applications benefit notably from the use of waterproof tablets. For example, industries like the food and beverage manufacturing sector require frequent hot water washdowns. This creates considerable amounts of steam that could severely damage the average consumer tablet (at the moment or over time).

A tablet’s waterproofness is measured using the International Protection (or IP) code and denoted using IP markings. This system is officially referred to as the IPXX system, with waterproofness indicated by the two variables at the end. These variables become numbers that demonstrate an item’s ability to withstand:

  • X – no data
  • 0 – water ingress
  • 1 – vertically dripping water (if exposure is ten minutes or less)
  • 2 – tilted dripping water
  • 3 – water sprayed against the item
  • 4 – water splashing against the item from any angle
  • 5 – water jets of 12.5 LPM at 30kPa and 3M distance
  • 6 – water jets of 100 LPM at 100kPa and 3M distance
  • 7 – immersion up to 1m in depth
  • 8 – continuous submerged operation as deep as 3m
  • 9 – water jets of 100 LPM at 100kPa and 3M distance at 80 degrees C

In some cases, an IPXX rating is followed by a letter, which notes additional information such as:

  • F – oil-resistance
  • H – high voltage
  • M – device in motion during testing
  • W – rated for special weather conditions
  • K – extra high pressure at close range (8-10 MPa)

Touchscreen Advantages

The touchscreens built into industrial tablets are far superior to those found in consumer-grade products. The average consumer tablet touchscreen cannot be utilized whilst wearing gloves or other protective gear; and, in some cases, water and electrical currents may interfere with the touchscreen and mitigate usability.

Ruggedized tablets rely on resistive touchscreens and offer exceptional sunlight readability for outdoor applications. Their capacitive touch screens allow users to leverage fingers, styli, and other tools to utilize these tablets in a range of conditions. Some common added features of these tablets include AF/AG/AF/POLARIZATION, ultra-LCD Protection, digitizer with high accuracy, and the ability to work with gloves or in wet conditions.

Wi-Fi, 4G LTE, Bluetooth, and GPS Wireless Connectivity

With complete wireless connectivity, including WiFi, Bluetooth, GPS, and blazing-fast 4G LTE Connectivity, the field workers can access or exchange data in real-time, ensures safety, efficiency, and reliability.

Multiple Operating Systems

Industrial tablets are designed to run on a range of operating systems, such as Android, Linux, and Windows. The ideal operating system is dependent on a number of factors. Rugged Android tablets offer a great deal of flexibility and prove an excellent solution in vertical industries. While rugged Windows tablets don’t offer the same OS customizability as an Android based tablet, they still offer strong performance in logistics, fieldwork and maintenance, industrial, oil and gas, mining, and commercial applications.
