Touch panel technologies are a key theme in current digital devices, including smartphones, slate devices like the iPad, the screens on the backs of digital cameras, the Nintendo DS, and Windows 7 devices. The term touch panel encompasses various technologies for sensing the touch of a finger or stylus. In this session, we"ll look at basic touch panel sensing methods and introduce the characteristics and optimal applications of each.

Note: Below is the translation from the Japanese of the ITmedia article "How Can a Screen Sense Touch? A Basic Understanding of Touch Panels"published September 27, 2010. Copyright 2011 ITmedia Inc. All Rights Reserved.

A touch panel is a piece of equipment that lets users interact with a computer by touching the screen directly. Incorporating features into the monitor like sensors that detect touch actions makes it possible to issue instructions to a computer by having it sense the position of a finger or stylus. Essentially, it becomes a device fusing the two functions of display and input.

It"s perhaps not something we think of often, but touch panels have integrated themselves into every aspect of our lives. People who enjoy using digital devices like smartphones interact with touch panels all the time in everyday life—but so do others, at devices like bank ATMs, ticket vending machines in railway stations, electronic kiosks inside convenience stores, digital photo printers at mass merchandisers, library information terminals, photocopiers, and car navigation systems.

A major factor driving the spread of touch panels is the benefits they offer in the way of intuitive operation. Since they can be used for input through direct contact with icons and buttons, they"re easy to understand and easily used, even by people unaccustomed to using computers. Touch panels also contribute to miniaturization and simplification of devices by combining display and input into a single piece of equipment. Since touch panel buttons are software, not hardware, their interfaces are easily changed through software.

While a touch panel requires a wide range of characteristics, including display visibility above all, along with precision in position sensing, rapid response to input, durability, and installation costs, their characteristics differ greatly depending on the methods used to sense touch input. Some typical touch-panel sensing methods are discussed below.

As of 2010, resistive film represented the most widely used sensing method in the touch panel market. Touch panels based on this method are called pressure-sensitive or analog-resistive film touch panels. In addition to standalone LCD monitors, this technology is used in a wide range of small to mid-sized devices, including smartphones, mobile phones, PDAs, car navigation systems, and the Nintendo DS.

With this method, the position on screen contacted by a finger, stylus, or other object is detected using changes in pressure. The monitor features a simple internal structure: a glass screen and a film screen separated by a narrow gap, each with a transparent electrode film (electrode layer) attached. Pressing the surface of the screen presses the electrodes in the film and the glass to come into contact, resulting in the flow of electrical current. The point of contact is identified by detecting this change in voltage.

The advantages of this system include the low-cost manufacture, thanks to its simple structure. The system also uses less electricity than other methods, and the resulting configurations are strongly resistant to dust and water since the surface is covered in film. Since input involves pressure applied to the film, it can be used for input not just with bare fingers, but even when wearing gloves or using a stylus. These screens can also be used to input handwritten text.

Drawbacks include lower light transmittance (reduced display quality) due to the film and two electrode layers; relatively lower durability and shock resistance; and reduced precision of detection with larger screen sizes. (Precision can be maintained in other ways—for example, splitting the screen into multiple areas for detection.)

Capacitive touch panels represent the second most widely used sensing method after resistive film touch panels. Corresponding to the terms used for the above analog resistive touch panels, these also are called analog capacitive touch panels. Aside from standalone LCD monitors, these are often used in the same devices with resistive film touch panels, such as smartphones and mobile phones.

With this method, the point at which the touch occurs is identified using sensors to sense minor changes in electrical current generated by contact with a finger or changes in electrostatic capacity (load). Since the sensors react to the static electrical capacity of the human body when a finger approaches the screen, they also can be operated in a manner similar to moving a pointer within an area touched on screen.

Two types of touch panels use this method: surface capacitive touch panels and projective capacitive touch panels. The internal structures differ between the two types.

Surface capacitive touch panels are often used in relatively large panels. Inside these panels, a transparent electrode film (electrode layer) is placed atop a glass substrate, covered by a protective cover. Electric voltage is applied to electrodes positioned in the four corners of the glass substrate, generating a uniform low-voltage electrical field across the entire panel. The coordinates of the position at which the finger touches the screen are identified by measuring the resulting changes in electrostatic capacity at the four corners of the panel.

While this type of capacitive touch panel has a simpler structure than a projected capacitive touch panel and for this reason offers lower cost, it is structurally difficult to detect contact at two or more points at the same time (multi-touch).

Projected capacitive touch panels are often used for smaller screen sizes than surface capacitive touch panels. They"ve attracted significant attention in mobile devices. The iPhone, iPod Touch, and iPad use this method to achieve high-precision multi-touch functionality and high response speed.

The internal structure of these touch panels consists of a substrate incorporating an IC chip for processing computations, over which is a layer of numerous transparent electrodes is positioned in specific patterns. The surface is covered with an insulating glass or plastic cover. When a finger approaches the surface, electrostatic capacity among multiple electrodes changes simultaneously, and the position were contact occurs can be identified precisely by measuring the ratios between these electrical currents.

A unique characteristic of a projected capacitive touch panel is the fact that the large number of electrodes enables accurate detection of contact at multiple points (multi-touch). However, the projected capacitive touch panels featuring indium-tin-oxide (ITO) found in smartphones and similar devices are poorly suited for use in large screens, since increased screen size results in increased resistance (i.e., slower transmission of electrical current), increasing the amount of error and noise in detecting the points touched.

Larger touch panels use center-wire projected capacitive touch panels in which very thin electrical wires are laid out in a grid as a transparent electrode layer. While lower resistance makes center-wire projected capacitive touch panels highly sensitive, they are less suited to mass production than ITO etching.

Above, we"ve summarized the differences between the two types of capacitive touch panels. The overall characteristics of such panels include the fact that unlike resistive film touch panels, they do not respond to touch by clothing or standard styli. They feature strong resistance to dust and water drops and high durability and scratch resistance. In addition, their light transmittance is higher, as compared to resistive film touch panels.

On the other hand, these touch panels require either a finger or a special stylus. They cannot be operated while wearing gloves, and they are susceptible to the effects of nearby metal structures.

Surface acoustic wave (SAW) touch panels were developed mainly to address the drawbacks of low light transmittance in resistive film touch panels—that is, to achieve bright touch panels with high levels of visibility. These are also called surface wave or acoustic wave touch panels. Aside from standalone LCD monitors, these are widely used in public spaces, in devices like point-of-sale terminals, ATMs, and electronic kiosks.

These panels detect the screen position where contact occurs with a finger or other object using the attenuation in ultrasound elastic waves on the surface. The internal structure of these panels is designed so that multiple piezoelectric transducers arranged in the corners of a glass substrate transmit ultrasound surface elastic waves as vibrations in the panel surface, which are received by transducers installed opposite the transmitting ones. When the screen is touched, ultrasound waves are absorbed and attenuated by the finger or other object. The location is identified by detecting these changes. Naturally, the user does not feel these vibrations when touching the screen. These panels offer high ease of use.

The strengths of this type of touch panel include high light transmittance and superior visibility, since the structure requires no film or transparent electrodes on the screen. Additionally, the surface glass provides better durability and scratch resistance than a capacitive touch panel. Another advantage is that even if the surface does somehow become scratched, the panel remains sensitive to touch. (On a capacitive touch panel, surface scratches can sometimes interrupt signals.) Structurally, this type of panel ensures high stability and long service life, free of changes over time or deviations in position.

Weak points include compatibility with only fingers and soft objects (such as gloves) that absorb ultrasound surface elastic waves. These panels require special-purpose styluses and may react to substances like water drops or small insects on the panel.

All in all, however, these touch panels offer relatively few drawbacks. Recent developments such as improvements in manufacturing technology are also improving their cost-performance.

The category of optical touch panels includes multiple sensing methods. The number of products employing infrared optical imaging touch panels based on infrared image sensors to sense position through triangulation has grown in recent years, chiefly among larger panels.

A touch panel in this category features one infrared LED each at the left and right ends of the top of the panel, along with an image sensor (camera). Retroreflective tape that reflects incident light along the axis of incidence is affixed along the remaining left, right, and bottom sides. When a finger or other object touches the screen, the image sensor captures the shadows formed when the infrared light is blocked. The coordinates of the location of contact are derived by triangulation.

While this type differs somewhat from the above touch panels, let"s touch on the subject of electromagnetic induction touch panels. This method is used in devices like LCD graphics tablets, tablet PCs, and purikura photo sticker booths.

This input method for graphics tablets, which originally did not feature monitors, achieves high-precision touch panels by combining a sensor with the LCD panel. When the user touches the screen with a special-purpose stylus that generates a magnetic field, sensors on the panel receive the electromagnetic energy and use it to sense the position of the pen.

Since a special-purpose stylus is used for input, input using a finger or a general-purpose stylus is not possible, and the method has limited applications. Still, this has both good and bad points. It eliminates input errors due to the surrounding environment or unintended screen manipulation. Since the technology was intended for use in graphics tablets, it offers superior sensor precision—making it possible, for example, to change line width smoothly by precisely sensing the pressure with which the stylus is pressed against the screen (electrostatic capacity). This design approach also gives the screen high light transmittance and durability.

The table below summarizes the characteristics of the touch panels we"ve looked at. Keep in mind that even in devices based on the same sensing method, performance and functions can vary widely in the actual products. Use this information only as an introduction to general product characteristics. Additionally, given daily advances in touch-panel technological innovations and cost reductions, the information below is only a snapshot of current trends as of September 2010.

Each touch-panel type offers its own strengths and weaknesses. No single sensing method currently offers overwhelming superiority in all aspects. Choose a product after considering the intended use and environmental factors.

Locate dirt, debris, residue, or blots/drops of anything that looks like it may fool the system into thinking a touch is being issued there. It is surprising how sensitive these overlays can be, and they have to be, for the most optimum performance.  So, to begin troubleshooting any touch issues, start by using a soft cloth and some 70% isopropyl alcohol to really wipe the screen down.   Inspect the inner LCD bezel for debris. Use a can of duster-air and/or folded piece of paper for the tight places.  Next, inspect the screen for scratches, pits or dents.  All of the above will produce results, such as, misaligned touch, or a cursor that is constantly retracting back to the same position.

(Touch Monitors Only) First, if using a touch monitor, start by resetting the USB cable on both, the computer, and touch monitor ends, and use a different USB port on the PC end.  If all USB ports are currently utilized, try swapping with another simple device, such as, a keyboard, mouse, memory stick etc. Avoid swapping with a printer, as this may produce printing problems.

If using a Touch PC or Touch Monitor, let’s start with Calibration.  Head to your Start Menu, select All Programsand locate the Touch Kit (XTS/XPC product line) or Touch Utility(EVO product line) folder, and locate your calibration option to begin.  Depending on your product line, you will find this under Tools or Devices.

If your touch is not responding at all, let’s insure the drivers are correctly installed.  Navigate to you Start Menu > right-click on Computer > Manage > Device Manager > and expand the, Mice and other pointing devices category.  Do you see aUTCRS232, URTC1000, or IdeaComentry? If so, do you see it listed with a yellow exclamation, or question mark? If no entry is found here, do you see it listed under the category Other Devices? If you see an entry and it is marked with a yellow icon, try the following:

If no entry is found, we need to insure the USB touch controller cable from the monitor, is directly plugged into the computer and not through a USB splitter / Hub.

Most people consider overhead and ambient lighting to be the biggest factor when it comes to light sensitivity. The light that computer and device screens emit can be just as troublesome. The way the screens are lit and how they perform when dimmed can affect how you feel.

LCD screens are backlight by a fluorescent bulb – and they have the same issues as any other sort of fluorescent light. Dimming LCD screens can helpful, since the less intense the light from a fluorescent is, the less intense the invisible flicker is. Screens that are too dark can cause eyestrain, so be sure you find a comfortable balance.

LED-lit LCDs are, unsurprisingly, lit by LEDs. LEDs can only be completely on or completely off. To simulate any brightness less than 100%, they must pulse on and off. Dimming these screens causes an invisible flicker that is otherwise not an issue with most LED screens. Just like with fluorescent lights, the flicker is undetectable to the human eye, but the brain can still pick it up and make you feel ill.

If you have an LED-lit LCD that bothers you try keeping the brightness at 100%. If that"s uncomfortably bright, try adjusting your computer’s white balance to make the light warmer or use a program like f.lux, which automatically changes the white balance according to the time of day.

Apple has determined that a small percentage of iPhone 11 displays may stop responding to touch due to an issue with the display module. Affected devices were manufactured between November 2019 and May 2020.

If your iPhone 11 has been exhibiting this issue, please use the serial number checker below to see if your device is eligible for this program. If so, Apple or an Apple Authorized Service Provider will provide service, free of charge.

Choose one of the options below to have your iPhone 11 serviced. Your iPhone will be examined prior to any service to verify that it is eligible for this program.

If your iPhone 11 has any damage which impairs the ability to complete the repair, such as a cracked screen, that issue will need to be resolved prior to the service. In some cases, there may be a cost associated with the additional repair.

If the resolution setting does not match the screen, the touch position will also be affected. For example, when you touch certain positions on the screen, it responds on correct points, but clicks on other positions may activate other areas next to them instead.

When the cursor is on the desktop, right click for the setting menu → click [Display settings ] → choose the touch screen (number 2 screen) and select the corresponding resolution(for example, On-Lap M505T resolution is 1920x1080), and then click "Apply".

Touch screens are found everywhere from our smartphones to self-serve kiosks at the airport. Given their many uses, it should come as no surprise that there are several touch monitor types. Each has its advantages and disadvantages and is suited to specific tasks.

That’s right. Long before your precious smartphone entered the market in the late 00s, touch panels had already been an established technology for nearly 4 decades.

It’s quite possible that you’re not clear on exactly what a touch panel is, what the touch panel types are, or how they’re applied in your daily life, beyond that of your smartphone. For that and more, we’re here to help.

Quite simply, touch panels, which are also known as touchscreens or touch monitors, are tools that allow people to operate computers through direct touch. More specifically, via the use of internal sensors, a user’s touch is detected, then translated, into an instructional command that parlays into visible function.

Delving deeper into the technical side of things, touch panels are not as cut-and-dry as they may seem. In fact, the way they sense and react to touch can widely differ based on their inherent designs. As such, there are 4 touch panel types in regular use – Resistive, Optical Imaging, Projected Capacitive, and Infrared. Below, we’ll dig into their specifics, which include their advantages, disadvantages, and real-life product applications.

Resistive touch panels are cost-effective variants that detect commands by way of pressure placed on the screen. This pressure sensitivity is generally limited to single-point touch, with a 20-inch maximum screen, which is fine for many usage cases. These range from styluses to fingertips. As a result, if used correctly, resistive touch panels will remain functional even if a water drop has landed on the screen.

As a result of this versatility, however, many will find that resistive touch panels are less durable than their competitors. Moreover, with its reliance on single-point touch, this touch panel type is not actually capable of multi-touch functionality. Regardless, resistive touch panels are often found in grocery stores, where stylus-based signatures are typically required after credit card purchases.

Some like it hot and some don’t. Infrared touch panels definitely fall into the latter category. By setting up a grid of infrared beams across the panel, which may be up to 150-inches, touch is detected by way of this panel’s disruption.

Although infrared touch panels are durable and support multi-touch functionality, it does possess one potential drawback. Depending on where you sit, literally.

Despite infrared implying heat, infrared touch panels actually perform rather poorly in it, particularly in direct sunlight. In those circumstances, the infrared light beams can be disrupted by the sun’s rays, as opposed to your fingers. As such, be sure to place your infrared touch panel device in an appropriately dark location.

Light, and the disruption thereof, is not just a great way to produce a shadow, but also to design a touch panel type. To take advantage of this principle, optical imaging touch panels are designed to sense touch through infrared cameras and the disruption of light strips. This can be achieved through any input you want, across its 100-inch maximum size, from gloves to bare hands, and beyond.

All in all, optical imaging touch panels are just about the most versatile option the touch-based world can offer. From durability to multi-touch, and universal input prospects, the possibilities may truly be endless. Although its only disadvantage may be its non-compact design, common applications of optical imaging touch panels include certain varieties of interactive whiteboards.

If you identify with the phrase, “go with what you know”, then projected capacitive touch panels are the touch panel type for you. For now, you can guess where you know it from.

By way of their electrical-based touch detection, Projected Capacitive touch panels are known for their high precision and high-speed response times. What’s more is that they possess multi-touch functionality and can be used within small, compact, yet expensive, devices. Due to their underlying technology, it has proven challenging to scale up to larger sizes. Figured it out yet?

Assuming you haven’t, or would like to enjoy the gratified feeling associated with being right, allow us to reveal where you interact with projected capacitive touch panels on a daily basis – Smart Phones! What’s more is that they’re not alone, with tablet computers and GPS devices also utilizing projected capacitive touch screens.

It would be a mistake to assume that the applications of all these touch panel types are limited to that of consumer-level devices, or even those that have been previously mentioned. Really, these touch panel types can be found throughout everyday life and in a variety of industries.

What’s more is that in many of these industries, these touch panel types are used less to market products to consumers, and more to sell solutions to businesses. Whether it be in regards to finance, manufacturing, retail, medicine, or education, there is always a need for touch-based solutions. In conjunction with the so-called ‘Internet-of-things’, these touch-based solutions play a key role in practices related to industry 4.0.

In practice, these solutions largely offer a form of personnel management. In hospitals, stores, or banks, for instance, these touch panel types can be used to answer basic questions, provide product information, or offer directions, based on the user’s needs. When it comes to manufacturing, on the other hand, these solutions enable employee management in the possible form of workplace allocation or attendance tracking.

At the end of the day, touch panels are here to stay. In the four decades since their inception, the level of adoption this technology has experienced is remarkable. They transform how we teach in classrooms and collaborate with colleagues.

Although you may not have been clear on the specific details of each touch panel type, we hope that you are now. This knowledge will absolutely serve you well, particularly if you’re interested in ViewSonic’s selection of touch-based solutions.

Even though you can see onlysix (6) main readings on the display, there isfourteen (14) usable functionsyou can access and adjust based on your needs.

Po2 – Km or miles per hour:depending on your location, you can select to display the speed in km (“0” ) or mph (“1”). For this to work properly, you need to set the size of your ebike wheels.

Po3 – Voltage of battery and motor:this is where you will specify the volts of your battery and motor. You can select 24v, 36v and 48v. Normally, the SW900 is set to 36v so make sure you select the right voltage grade.

Po4 – Display sleep mode:this come from zero to 60 mins. In this case, zero means your controller will stay on all the time and if 60 mins, it will shut down after 1 hr of no operation (this will not happen if you are riding your electric bike though).

Po5 – Pedal Assist levels (PAS):there is a total of five (5) PAS. You will see a bunch of numbers with “v” next to it (meaning voltage), so don’t freak out cos you don’t need to do anything with that. In simple words, you can choose“zero”for 1 to 3 levels of PAS and“one”for 1 to 5 levels of PAS. I personally like the“one”setting, since it lets the system deliver more sensitivity in term of my pedaling efforts.

P06 – Wheel size selection:this is where you establish the size of your wheels in inchs. This is important in order to display the right speed you are traveling.

*P07 – Speed measuring magnet:this element will be factory calibrated so better not to mess with it. Basically, based on the assistance mode you select and speed limit, it will tell the controller if the motor is delivering the right assistance and therefore if the battery is delivering the correct voltage. This is very important in order to indicate the controller to deactivate the motor if you reach your set speed limit. Ask your trusted bike shop what would be the right setting if you change the ebike motor.

P08 – Speed limit:this is a very important setting since it will help you set the right speed that will comply with the local regulations and your comfortable riding speed.

P09 – Zero and Non-Zero Start:This relates to the throttle device activation. A non-zero start means the throttle will have a delay reaction of 1 sec. I believe this relates to safety rather than messing with your patience.
