At e₂ip, we perform a variety of human-machine interface (HMI) treatments to promote more efficient, safe and reliable user experiences (UXs):

Anti-Reflection (AR) Coating: Enhance Optical Clarity

When it comes to human-machine interfaces, clarity is a must. The problem is that your display is typically a reflective surface. Anti-Reflection (AR) coatings or films, however, offer a practical solution to this age-old problem. By applying a thin film or coating to the front surface of the glass surface of the LCD display, these treatments filter or cancel out reflections and enhance optical clarity. 

Anti-Glare (AG) Coating: Reduce Distractions

In environments where ambient light sources can impede visibility, such as outdoors or under bright indoor lighting, Anti-Glare (AG) treatments come to the rescue. Employing an etching process, AG treatments impart a matte finish to the front surface of the glass lens. 

 

This simple yet effective solution reduces the adverse effects of reflected images or light sources on the screen surface. This treatment allows users to interact comfortably with your displays without distractions caused by glare.

Anti-FingerPrint (AF) and Anti-Smudge (AS) Treatments: Clean and Clear Displays

Fingerprints and smudges are a nuisance to touch surfaces: they not only affect the aesthetics of the interface, but the user-experience as well. Our Anti-finger print (AF) coating and Anti-smudge (AS) treatments and coatings address this issue head-on. 

 

By creating an ultra-smooth surface on the glass lens, these treatments minimize the adhesion of oily residues, making fingerprints and smudges a thing of the past. The smooth surface also reduces finger friction, which makes it even easier to navigate the screen.

In-Mold Electronics (IME), or Smart Structural Surfaces™, promise to be a game-changing technology that will significantly improve process optimization. 

IME provides for a streamlined production process over traditional electronic assembly. Simply put, IME is a three-step process which includes the printing of electronic circuits and graphics, followed by the forming and molding. However, In-Mold Electronics is often confused with related processes, namely In-Mold decorating (IMD) and In-Mold Labels (IML).

What is the Difference Between IML and IMD?

IME’s roots are tied to both IMD and to a lesser degree IML. IME takes the process of printing, forming, and molding to a new level of complexity. Both IMD and IML offer a streamlined process utilizing printing, forming and molding. All three offer an enhancement in the production of parts with complex 3D geometries. 

An In-Mold Decorating or In-Mold labeling process only offers a decorative function. Typical examples of IMD include molded plastic parts, such as mobile phone covers. In-Mold labels can be found in a broad variety of plastic containers and consumer packages, such as for ice cream tubs, shampoo bottles, and many more. 

                   

In-Mold Electronics specifically describes a more complex process which, like IMD and IML, begins with fundamentally the same three primary processes of printing forming and molding. However, IME is dramatically different in that it marries electronic functionality to the decorative process making the part a functional Human Machine Interface (HMI) for industrial or consumer applications. These parts are referred to at E2IP as Smart Structural Surfaces™. 

Smart Structural Surfaces™: A Step Forward for IME

The IME process begins by printing stretchable conductive inks onto a film to create fully functional electronic circuits. A graphic overlay is printed onto the second film. These graphics align with the electronic circuitry and can include icons for intuitive user interaction as well as to serve the aesthetic design. The films are then thermoformed into the desired 3D shape. Electronic components can be added to the circuits before or after thermoforming. The part can include lights, sound and haptic feedback. The graphic layer and the circuit layer are placed together in the mold cavity of an injection mold. The injection molding embeds all the components creating a single, rigid molded plastic part.

Smart Structural Surfaces™ offer a range of benefits over traditional HMI components, including increased durability, reduced manufacturing costs, and improved design flexibility. By eliminating the need for additional assembly and reducing the number of components needed, Smart Structural Surfaces can significantly reduce production costs and waste.

Why Is Sustainability Important for the Electronics Industry?

Sustainable choices are important for the industry because they conserve precious natural resources and protect the environment.

Manufacturers can use environmentally friendly materials that can be recycled easily in order to reduce their impact on the environment. By doing so, they can help to remove these materials from the waste stream and prevent them from contributing to pollution and other environmental problems. Additionally, by paying attention to the carbon footprint of their supply chain, manufacturers can reduce their overall impact on the environment by minimizing the amount of greenhouse gases that are emitted during the production and transportation of their products. By taking these steps,

manufacturers can send a message to consumers that they are committed to ethical, sustainable, and carbon neutral practices. This can help to attract consumers who are increasingly seeking out products that align with their values and support a more sustainable future.

How Can Electronics Be More Sustainable?

To measure the environmental impact of electronics, you have to look at several factors, including the design process, the manufacturing production cycle, the raw materials, and the recycling of materials after use. Each electronics product has a different life cycle, so environmental impacts can vary from one product to the next.

Take a look at some of the options and novel solutions available for lightening the environmental load of electronics products.

Printed Electronics

Printing electronics drastically limits the amount of fossil materials used, as thin electronics and wearable devices are printed on various substrates using either traditional or novel printing equipment. In addition, energy consumption is significantly reduced with printed electronic components. Printed electronics are useful for flexible displays, sensors and various human-machine interfaces.

Use of Hazardous Chemicals

Many electronics products use heavy metals and toxic chemicals that are harmful to human health. These include lead, mercury, cadmium and various flame retardants. Electronics manufacturers can help manage these hazardous materials through eliminating PVC (polyvinyl chloride) from their power supply and cabling products and by choosing materials that don’t need flame retardants.

Energy Efficiency

Manufacturers can look for ways to save energy during the production of devices. They can also design products that are energy-efficient by tapping into ENERGY STAR features and adding low-power standby modes. Self-powered devices that offer energy harvesting from body motions lower energy demand, and use of supercapacitors reduces the need for lithium batteries.

Product Design and Materials Management

Products that require fewer resources and materials tend to generate less electronic waste at their end of life. It may be possible for some manufacturers to switch to sustainable materials such as vegetable-based plastics, recycled plastic, aluminum or recycled glass to minimize e waste as well. The same can be done with product packaging to lower each product’s overall carbon footprint. In addition, designing products that need reusable batteries rather than single-use batteries helps.

Sustainability for Consumers: How to Buy Electronics Ethically

Consumers play an important role in developing sustainable electronics. The more they demand eco-friendly electronics and a sustainable future, the more the technology industry responds.

They can pay attention to the supply chains used by their favorite brands. In the past, buyers had no way to know when a company was using child labor in developing countries, for example, in an effort to gain a competitive edge. Now, organizations such as Amnesty International have provided evidence showing that electronics companies are often responsible for human rights abuses.

When consumers put pressure on shareholders and companies, demanding ethical supply chains, living wages for workers, use of recycled materials, lowered carbon emissions, and other sustainable production choices, the industry is bound to take notice and make smart choices.

This post will delve into some of the challenges and opportunities for this technology to play an important role in the future of printed electronics and human-machine interfaces.

An Overview of The Screen Printing Process

At its core, screen printing involves creating a stencil of the desired image on a screen, and then using that screen to transfer the image onto a substrate. In this additive process, stencils are used to transfer inks or other materials onto the substrate. The “stencil” is essentially a screen that allows the ink to pass through onto the substrate below. Screen printing is a versatile process that can be used for a wide range of substrates, including flexible materials.

Although screen printing is most commonly associated with printing photographic images, a similar process is used to create printed electronics. In this type of manufacturing, advanced mesh screens and conductive inks are used to create functional electronics on a wide range of flexible substrates.

One advantage of screen printing is that it can be used to print very thin and precise patterns on a diverse range of substrates. Additionally, screen printing can be used to create multilayer prints with high accuracy and repeatability. This makes screen printing an excellent choice for printed electronics applications.

Printed Electronics Advantages

Screen-printed electronic components offer several advantages over traditional wires and circuitry. Wear and tear from use, combined with the potential for oxidation, tends to limit the lifespan of electronic components, however, printed electronics do not share these limitations. Printed circuit assemblies are lightweight, sturdy, and long-lasting.

Printed electronics are typically thinner and more flexible than conventional electronic components, which can improve the ergonomics of an assembly. Also, printed electronics are printed directly onto a substrate, which eliminates the need for separate printed circuit boards or other wiring harnesses, which reduces the overall size and weight of an assembly, as well as the number of potential failure points. Most importantly, printed electronics can be custom-tailored to specific applications, which allows for far greater design freedom and flexibility. For these reasons and others, printed electronics will continue to significantly improve the capabilities, performance and reliability of human-machine interface assemblies.
