If we look at any modern manufacturing facility, we can see how each piece of machinery plays a key role in a broader system of assembly, processing, or fabrication. Within this system are the often underestimated small LCD screens that display all the information we need to know to guide these processes and make sure everything is running smoothly.

These LCD Displays are found everywhere, from the microwave heating up your food to the entertainment system in your car. But they’ve also become integral for diverse manufacturing processes to improve efficiency and overall operations.

How Is LCD Technology Used in the Manufacturing Industry?

Within the manufacturing line, there are many ways that LCD technology has become essential to its digitization and automation. While operational efficiency is one of them, they can also offer other benefits like lowered energy costs and quality control.

  • Machine Interfaces – The most apparent way LCD technology is used in manufacturing is for operator interfaces on machinery. These screens display important information about the machine, whether it’s speed, pressure, temperature, or other sorts of real-time data or operational instructions. This in itself helps to improve productivity and reduce the chance of human error.
  • Quality Control – Along with displaying factual information about machinery, LCD panels also help with quality control and inspection. Using a camera to zoom in on components, these panels can be used to uncover overly minute details that aren’t detectable with the naked eye. This is especially useful in certain industries like pharmaceuticals or microelectronics.
  • Equipment Monitoring – Part of keeping the manufacturing process smooth is being proactive. Small LCDs can display information from sensors around a factory. This provides real-time notification when equipment needs maintenance and minimizing costly downtime.
  • Assembly Lines – Throughout the manufacturing process, regularity and consistency often determine the quality of the outcome. LCD technology can display statistics and process data that aid with precise control and regulation. This benefit is particularly noticeable with automated assembly lines.
  • Data Collection Stations – Many manufacturing facilities have data stations that outline things like production metrics, timesheets, and other information. Metrics such as these can improve manufacturing operations. LCDs can offer clear and crisp displays that can showcase both dynamic and static content.

Types of LCDs in the Manufacturing Industry

The components and needs of the manufacturing industry are so varied. Because of this, there is a wide variety of LCDs made to suit each of them.

  • TFT Displays – TFT displays are best used for their high resolution and vibrant color quality. Using thin-film transistor technology, the display allows for better image quality in situations requiring detailed visual information. They offer several advantages: a wide viewing angle ensures clear visibility from various vantage points within an area, and high color depth capabilities enhance the handling of color-coded data.  Often times, these displays integrate a capacitive or resistive touch panel to improve the user interface.
  • Character Displays – Conversely, character displays show text or numeric data in predefined patterns. They display a set number of characters, which makes them most suitable for basic interfaces like meters and timers. Thanks to their simplicity and lower cost, they’re very accessible in comparison to other displays.
  • Graphic Displays – Graphic displays offer a more sophisticated way to display data. While they’re able to display text, their primary draw is their pixelated grid that can present more detailed visual data. These grids are capable of displaying drawings, graphs, and symbols, which make them a great choice for applications that need a more graphical interface. These are optimal for applications requiring more data output than a character display or the ability to display different menus.

Challenges in Implementing LCDs and How to Overcome Them

Incorporating LCD technology into a manufacturing space offers a host of benefits, but the implementation process isn’t always smooth. This is especially true if you’re inexperienced with LCD technology. That’s why there are a few considerations that you’ll want to keep in mind before opting for a specific LCD.

Challenge 1: Lifetime

Nothing is more frustrating than designing a new product and then finding out that a component on the bill of materials (BOM) has gone obsolete one year into production.  Unfortunately, LCDs are a component that this can be common with as well.  One recommendation is to work with an LCD manufacturer that specializes in providing displays for industrial equipment and other similar industries that require long product life such as medical, mining and test and measurement applications.

Challenge 2: Environment Concerns

External factors such as temperature, vibration and lighting can affect the performance of LCDs. The display might be hard to read in sunlight. Additionally, the responsiveness of an LCD may be affected by extreme temperatures. Working with an LCD manufacturer that specializes in displays for similar environments ensures optimal performance and durability. For example, selecting a sunlight-readable LCD will ensure the screen is easy to read and can operate in bright environments and planning for a high-vibration environment can help in selecting an LCD which is capable of withstanding high-vibration uses for years of use.

Challenge 3: Integration with Existing Systems

Integrating new LCD technology with an existing manufacturing system can also be a major challenge. Compatibility issues prevent these screens from working with your existing machinery and software, practically rendering them useless. However, designing an LCD to align more closely with existing firmware can minimize the need for changes to the current system. Manufacturers should consult their LCD supplier for appropriate recommendations in order to make sure the technology they choose is suitable. 


LCD technology acts as the eyes and ears of the busy manufacturing world, working to help control, monitor, maintain, and advance our existing systems. And with the rise in advancements and improvements in the sector, they will only continue to influence the way manufacturing units function – in terms of productivity, efficiency, and a lot more.
