Touch panel ESD protection

Touch panel ESD protection for medical tablet and panel PC

Industrial panel PC with ESD protection

With the evolution of touch screen technology, touch interface has been gradually taking its place in life as one of the most effective user interfaces. We have become accustomed to using electronic products like our own smartphones, tablets and kiosks, ATMs, vending machines, electronic information systems in public places with touch screens. The healthcare industry is another area with rapid adoption of medical tablets, touch panel PCs, medical devices with touch panels and other touch related medical computers.

As any user accessible areas can be subjected to Electrostatic Discharge (ESD) strikes, all products with touch panels require some sort of ESD protection. Their electrostatic discharge problems need to be addressed to meet international standards. Electrostatic discharge can be very harmful to computer systems. Even a small amount of voltage can damage components and cause system failure.

Product reliability is an important factor for hardware and software on the design of industrial panel PC and medical tablet computers with touch panels built-in. This article will provide information on touch panel ESD protection, Electromagnetic Compatibility (EMC) standard ESD tests and requirements for medical devices and industrial computers.

Touch panel ESD protection

A typical projective capacitive touch panel consists of three major components, a glass protective cover, a capacitive touch sensor layer and a touch controller circuit. The touch controller circuit traditionally exists on a separate FPC. On one side of the FPC, the touch controller IC is responsible for monitoring the electric field around the panel with a series of electrodes in the touch sensor. If an object is placed in close proximity, it detects the change and records the location information.

Touch panel ESD protection

The touch controller is designed to sense electrical variation on the surface of the panel. The environment or human with large electrostatic charge to touch the panel will let the controller sensed a huge noise. The touch sensor pins of the touch controller IC will inevitably contain ESD protection circuits. The huge trigger signal will send through the ESD protection circuit and flow into the power or ground lines of the controller.

On the other hand, the FPC connection to the main board can also expose the touch controller to ESD pulses introduced at the system level. Examples of these ESD channels include USB, Ethernet or other exposed interfaces of the system. When the power increases to more than the touch controller IC’s ESD protection limit, it will damage the IC, or cause internal circuit malfunction.

To solve the problem of electrostatic discharge with touch panels, many techniques can be applied, including mechanical design, production control, system circuit or component characteristic design. The basic principle is to protect the key components like the touch controller IC. Most EMC hardware design measures can be applied to ESD immunity improvement for touch panels, including power supply design, layout considerations, I2C pull up considerations, metal part grounding, adding external ESD protection, etc.

In addition to hardware measures, software measures can also be implemented to deal with some other touch panel related ESD problems. For example, in our touch panel PCs PPC-4310, touch controller ESD watchdog feature of the firmware is enabled. It allows the reset of the touch controller and recovery of the touch function from non-destructive ESD events.

Tablet computer and panel PC ESD tests

Electrostatic discharge (ESD) tests for tablet computers and industrial panel PCs for measuring ESD are based on IEC 61000-4-2. It defines the range of test levels in relation to different environmental and installation conditions and establishes the appropriate test procedures. The objective of the standard is to establish a common reproducible basis for evaluating the performance of equipment subjected to ESD protections.

There are two types of tests based on the international standard, contact discharge and air discharge. The following is an IEC 61000-4-2 specifying compliance levels of ESD tests. A common test level for industrial panel PCs is 6kV contact, 8kV air, but these values could be higher or lower depending on the product standard requirements.

IEC 61000-4-2 ESD test classification:

IEC 61000-4-2 ESD test classification

Where “x” can be any level in between the other levels.

Medical tablet and panel PC ESD test requirements

The new EMC standard for medical devices, such as medical tablets and panel PCs is IEC 60601-1-2 standard. It includes increased testing limits for electrostatic discharge (ESD), radiated radio-frequency (RF) immunity, surge immunity, and electrical fast transients (EFTs). The standard outlined in IEC 60601-1-2 for measuring ESD is following IEC 61000-4-2 mentioned above.

Touch panel ESD protection for medical tablet PCs

One of the significant revisions to the immunity standard IEC 60601-1-2 is the increased ESD level. The contact discharge level is increased from 6kV to 8kV, while air discharge level is increased from 8kV to 15kV. This is the same as the Class 4 of the IEC 61000-4-2 standard.

Estone’s medical grade tablet computers and industrial panel PCs go through a series of rigorous product development processes. They are designed to meet IEC 61000-4-2 or IEC 60601-1-2 ESD test standards for product quality and reliability to use in the medical field.

EM-2100 Medical Panel PC

Antimicrobial coating on medical tablets and panel PCs

With the rapid adoption of medical tablets, touch panel PCs, touch screen medical devices and medical computers, the healthcare industry leverages the innovative technologies and features immanent in these types of devices. Medical computers used for telemedicine are some of the examples of those we see in recent headlines, which provide patients and providers solutions for virtual care without face to face visits.

Antimicrobial medical computer

However, preventing the growth of microbes, bacteria transferring through touch screens or the surface of medical computers has become more and more challenging when many of these computers, such as medical tablets and medical panel PCs, are widely used in hospitals, outpatient clinics, nursing homes and other healthcare settings.

On the other hand, even in medical treatment settings, according to CDC’s estimates, one in 31 hospitals patients has at least one healthcare-associated infection (HAI) on any given day. This became even more relevant recently as we are experiencing the COVID-19 pandemic. A HAI contracted during care is the last thing any health facilities visitor or hospital patient expects or needs.

Antimicrobial coating

Antimicrobial coating on medical computers is used to inhibit the growth of bacteria, mold and mildew, prevent the surface transferring of bacteria and reduce the spread of infectious diseases. Unlike cleaning agents and disinfectants often used in health care facilities, active ingredients added to the antimicrobial coating on medical tablets and touch panel PCs provide protection against microbes around the clock, which in turn prevent them from spreading. The antimicrobial substance integrated to the antimicrobial coating typically contains silver ion antimicrobials, zinc antimicrobials and copper antimicrobials.

Silver ions, for example, is suitable for a wide range of materials and applications, including medical coatings, antibacterial films, plastics and powder coating products. For medical devices with touch panel PC, medical tables and medical computers, if the surfaces are protected with silver ions antimicrobial additives, the amount of bacteria on some of those surfaces can be reduced by 99.9%. The antibacterial coating also prevents the spread of fungi.

Antimicrobial touch screens

Antimicrobial medical tablets

Displays with touch panels are becoming more and more popular in medical devices. Medical tablets and panel PCs are often used in surgical displays, patient monitoring units and hand-held devices to improve patient care and productivity. Each time people use these touch screen devices, there is a risk that each of them leaves their mark in the form of more or less dangerous bacteria. Antimicrobial coating on touch screen glass will provide continuing protection in this situation.

The following is an example of the test results of one of the touch screen cover glasses used in one of our ODM products. The test is based on JIS Z 2801:2010 standard for antibacterial products. The test result shows antibacterial activity and efficacy.

Table 1: Antimicrobial touch screen cover glass test result

Antimicrobial enclosures

MD-100 Medical Tablet PC

Besides the touch screen, the enclosure surfaces of medical tablets and panel PCs also need to be protected to reduce the growth and spread of microorganisms. To add antimicrobial protection for plastic enclosures, antimicrobial additives based on a natural active substance in the form of silver can be added to the polymer for injection molding. In the case of metal enclosures, antibacterial powder coating options are available based on specially formulated silver ionic technology. Without antimicrobial coating, the enclosure surfaces will require cleaning often and may degrade with the heavy use of disinfectants or strong chemicals.

The following is the test result of an antibacterial plastic enclosure material used in one of our medical grade tablets. The test is with reference to ISO 22196:2011 standard for measurement of antibacterial activity on plastics and other non-porous surfaces.

Table 2: Antibacterial plastic enclosure material test result

Healthcare-associated infection and other risks of infection cause enormous costs throughout the world, especially for healthcare facilities, hospitals, nursing care facilities, home healthcare services and clinics. It is important to utilize antimicrobial technology to protect the surfaces of medical computers that are in high risk of contamination with germs and require ongoing protection even between cleaning cycles.
