How Optical Bonding can transform your touchscreen

Touchscreens are designed to be easy to use, along with a superb display and visuals. But what happens when you lose those visuals due to glare and reflection from direct sunlight or bright lights. In most displays, there will be an air gap between the LCD and the glass panel. This air gap causes reflections by light refraction at the surfaces of the display and the touchscreen.

So how do you avoid bright light affecting the display and making the visuals stand out even more? 

It is achieved by a process called Optical Bonding. This is a protective highly transparent adhesive in the gap between the touchscreen and LCD. The main purpose of optical bonding is to improve the displays visuals and clarity. This method eliminates the air gap between the cover glass and the display meaning the contrast and brightness of the colours are increased.  

Other benefits from the use of Optical Bonding include,

  •       Increased durability as the touchscreens strength is improved which makes it more resistant to glass breakage.
  •       Improved heat dissipation by filling the insulating air gap between the components, heat can be derived to the outside.
  •     No condensation moisture can occur and no dust or dirt particles can enter by filling the insulating air gap.

SCHURTER can offer Optical bonding for your touchscreen solution so contact us to find out more – we’re happy to help.

Why your business can benefit from touchscreen technology


Touch technology is a big part of our everyday life, but why can they be a great investment for businesses? Let’s take a look at our top 3 benefits of touch screens.

1: Cost Reduction
You may think investing in touchscreen will cost you instead of reducing costs, however once implemented into your business a touchscreen interface increases accuracy and reduces time to get used to the equipment. This will improve efficiency and will eventually keep costs down. This also will mean more work can be completed. This to will apply when it comes to training users. It simplifies processes and requires minimal training and instructing for users.

2: Speed
In today’s world, speed is everything and it’s no different when it comes to business and touchscreens. Touchscreens help us operate any device faster, Touchscreens allow users to select icons directly and efficiently. All users can use touchscreens that allow them to operate the device directly, instead of through a tool. This means a touchscreen interface can allow any member of the company the chance to use and benefit from a touchscreen at a much faster pace.

3: Ease of use
Touchscreens, when compared with other input methods such as a keyboard and mouse, come out on top for ease of use. It makes it simple for users to navigate the system, selecting the right button or menu item on a screen has never been easier. While the usual combination of keyboard and mouse is familiar to most users, the action of touch comes even more natural, even to people without any computer literacy. This then reduces training time, with less time training there is more time for employees to work and add to the growth of the company.

We hope that these points have informed you enough to know that touch screen technology can add to your business. If you want to find out more, then please contact us at SCHURTER.

Better to Check than Retrofit

Switched mode circuits are being used increasingly in electronic equipment. Because of the rapid switching the probability of high frequency interferences is also increasing. At the same time the legislator is tightening the EMC regulations. The outcome: The leeway for retrofits with filters and chokes is growing smaller. Therefore, SCHURTER has set up a mobile service for wired EMC measurements. It allows a regular check of new machines and equipment during the development process.

The use of CE-compliant assemblies can mislead many a device designer to dispense with the EMC testing. Yet the task of squaring of the circle which guides the assembly of CE tested components, leading in the end to a device that is compatible with the standard, is becoming more and more difficult. The mode of operation, the wiring and the assembly of the components have such a great effect on the emissions that it is advisable to measure them first. 

As a supplier of installation filters and chokes, SCHURTER is also involved in the development processes of its customers. The outcome is recognition that the EMC problems for the manufacturers are associated with increased risks. 

If attention is paid too little or too late to the EMC requirements, there is a threat of delays in obtaining marketing authorization; with all the potential negative consequences for a company. A subsequent re-engineering leads to rising costs; the roadmap leading to series production must be revised and, in the worst case scenario, supplier loyalty is at stake. 

Therefore SCHURTER decided many years ago to add a mobile EMC measurement service to its range of EMC products. At present, about 1000 companies in Switzerland, Germany, Austria and northern Italy are being served. In other European countries, Asia and North America SCHURTER offers the service through its global network of partners.

The measurements in the actual environment give a more accurate indication of the susceptibility to interference than the laboratory environment can simulate. In addition, the wired measurements of electromagnetic compatibility on site bring the customers four key advantages:

1) Logistical simplification: many businesses avoid ongoing EMC checks during the development processes for reasons of cost. The machines or equipment must be disassembled, packaged, loaded and taken to the laboratory. The SCHURTER measurement service eliminates this expense. The staff sets up its testing equipment on site, right where the customer requires it. 

2) Integrated consultation: if an EMC limit value exceeds the authorized level, the SCHURTER measuring engineers provide immediate assistance. They either adjust the filters to the system requirements or they offer recommendations about optimizing the equipment design, wiring or power supply.

3) Conclusions with regard to wireless measurements: remote measurements of electromagnetic radiation required for a CE authorization cannot be replaced by a cable measurement. However, it provides valuable indications and reduces the risk of experiencing unpleasant surprises during measurements in the laboratory. 

4) Flexibility: in a testing laboratory the measuring environment can be controlled. That is impossible during a measurement in the field. Close to an industrial production, for example, electromagnetic background noises can dominate because of the high network load. In order not to disrupt the operational flows SCHURTER measurement technicians are also available during off-peak hours or at night.

In general, ongoing EMC checks during the engineering processes represent a useful addition to operational quality and risk management. With regard to the entry into force of the new European EMC directives, however, they acquire quite a special significance. 

Directive 2014/30/EU requires manufactures to expand substantially the technical documents for recently introduced devices. Beginning mid-2016 they must contain a "suitable risk analysis and assessment". 

Smaller devices can also be measured in one of the company’s own EMC laboratories. With its own development and production SCHURTER has acquired a wealth of sound EMC knowhow.
