difference between lcd touch screen digitizer brands
Your iPod, iPhone and tabletare commonly known to have three key components: a glass panel, digitizer (aka touch screen) and LCD. What are the differences? Let’s clearly define these layers:
Digitizer –The digitizer is located just under the glass screen. It is the electrical force that senses and responds to touch. When you tap your fingertip or swipe it across the screen, the mere touch acts as data input to the device’s center. If your device fails to respond to touch, it’s time for a new digitizer. The digitizer is an electrical mechanism that is fused with the glass screen; so if you need to replace the digitizer, you’ll have to replace the glass, too, and vice versa. UEGoffers a Front Glass (Digitizer Touch Screen) Repair Service on tablets.
Touch Screen – The term touch screen is interchangeable with the term digitizer. You’ll often see the combined terms Digitizer Touch Screen offered as a repair service.
LCD – LCD is an acronym for liquid crystal display. The LCD is the visual component underneath the glass that displays the image on the screen. UEGoffers LCD repairs on tablets, iPhonesand iPods.
LCD (liquid crystal display) is the technology used for displays in notebook and other automated industry computers. It is also used in screens for mobile devices, such as laptops, tablets, and smartphones.
Like light-emitting diode (LED) and gas-plasma technologies, LCDs allow displays to be much thinner than cathode ray tube (CRT) technology. LCDs consume much less power than LED and gas-display displays because they work on the principle of blocking light rather than emitting it.
Each LCD touch screen monitor contains a matrix of pixels that display the image on the screen. Early LCDs screen had passive-matrix screens, which controlled individual pixels by sending a charge to their row and column. Since a limited number of electrical charges could be sent each second, passive-matrix screens were known for appearing blurry when images moved quickly on the screen.
Modern LCDs display typically use active-matrix technology, which contains thin film transistors, or TFTs touch screen. These transistors include capacitors that enable individual pixels to "actively" retain their charge. Therefore, the active-matrix LCDs touch panel are more efficient and appear more responsive than passive-matrix displays.
The backlight in liquid crystal display provides an even light source behind the LCD screen. This light is polarized, meaning only half of the light shines through to the liquid crystal layer.
The touchscreen panel a display device that senses physical touch by a person’s hands or fingers, or by a device such as a stylus, and then performs actions based on the location of the touch as well as the number of touches.
Touch screen glass can be quite useful as an alternative to a mouse or keyboard for navigating a graphical user interface. Touch screens are used on a variety of devices such as computer and laptop displays, smartphones, tablets, cash registers, and information kiosks.
A touch-screen digitizer is one piece in a multilayered "sandwich." In modern devices, the screen that produces the images is found at the bottom layer; the digitizer is a transparent sheet that occupies a middle layer on top of the screen, and a thin sheet of hard, protective glass forms the top layer.
Touching the screen triggers touch sensors immediately under your fingertip; a specialized electronic circuit receives signals from these sensors and converts them into a specific location on the screen as X and Y coordinates. The circuit sends the location to software that interprets the touch and location according to the app you"re using.
For example, when you dial a phone number, your fingers touch the numbers on a virtual keypad on the phone"s screen. The software compares the locations touched against the keypad and generates a phone number one digit at a time.
Touch Screen Glass– The bottom layer is the ITO glass, typically thickness is between 1 and 3 millimetre. If you drop your device, the cracked glass ends up resembling an elaborate spiderweb.
Digitizer – The digitizer is located above the glass screen. It is the electrical force that senses and responds to touch. When you tap your fingertip or swipe it across the screen, the mere touch acts as data input to the device’s center. If your device fails to respond to touch, it’s time for a new digitizer.
The touch screen digitizer is an electrical mechanism that is fused with the glass screen; so if you need to replace the digitizer, you’ll have to replace the glass, too, and vice versa.
Touch Screen Panel- Touchscreen is the thin transparent layer of plastic, which reads the signal from the touch and transports it to the processing unit. It is the part that you can touch without disassembling the device.
LCD – LCD display is an acronym for liquid crystal display. The LCD is the visual component underneath the glass that displays the image on the screen. You can not get to the LCD without taking the device apart first.
A touch screen display is usually made with three main parts. The protective glass sheet, the digitizer sheet, and the LCD. The digitizer is a thin transparent sheet that is adhered to the protective glass sheet with a transparent conductive adhesive. The digitizer is the only part of the display assembly that is responsible for sensing touch. Since the human touch is conductive it allows the screen to sense the location you touch. The LCD is only responsible for displaying the image on the screen. If the screen is not responding to touch then usually the digitizer is damaged or faulty. Usually a damaged or cracked LCD will display a distorted image or no image at all. So if the phone displays a good image but does not respond to touch then you may have the option of only replacing the digitizer. It"s not as easy of a repair as replacing the whole display but is cheaper. A new digitizer part already has the digitizer sheet adhered to a protective sheet of glass. If a person can remove the faulty digitizer from the phone without damaging the LCD then it is surely more cost effective repair. Some displays have the digitizer fused to the LCD which makes it hard not to damage the LCD if trying to remove the digitizer. If that is the case with your phone"s display it is a lot easier to just replace the whole display. Hope this information is helpful.
Most of the time people don’t know the difference between a touchscreen and a LCD screen. When there are dark black blobs on your screen, it’s not because the display screen is damaged, it is the caused due to the damage in the LCD of your mobile phone whereas when there are cracks on your screen its mainly due to the damaged caused to your touchscreen and as compared to an LCD screen it is easier to fix as you only need to replace the display screen of you mobile phone.
An LCD is the part of a phone that displays the image we see on screen. It is the layer which produces and displays the image, therefore if the LCD is damaged you can still use the touchscreen although the panel would have either the aforementioned dark black blobs or the spider web type dark cracks on the display or both it would still function normally. To repair the LCD, a technician would have to pull apart the phone part by part to reach the LCD and assess the damage done which is not required for a touch screen. LCD, which is a liquid crystal display, is widely used in mobile phones as it uses low power and produces good quality images.
The images which are displayed in a LCD are produced through small elements which are called pixels. Pixel is a word everybody is familiar with but what exactly is a pixel? Pixel is made up of a layer of molecules lined up between two transparent electrodes and polarizing filters. There are several types of LCDs, reflective, transmissive and transflective, each has a specific function. A transmissive LCD can produce a clear and good quality image in low light while Reflective screen can produce a very good image in bright light. The transflective screen as the name indicates can produce a good quality image in both conditions, hence it is a mixture of both transmissive and reflective LCD.
Touchscreen is now a part of almost every digital gadget in the 21st century. From mobile phones and laptops to TVs and switch boards, it is now used almost everywhere your eyes fall on. But what exactly is a touchscreen? A touchscreen is basically a device which allows us to directly interact by using our fingers or a stylus. The stylus is a special kind of pen whose tip is covered with a unique coating which allows it to directly interact with the computer. We can use one finger or multiple gestures to interact with a touchscreen device. It doesn’t require a mouse or any alternative device such as a keyboard for navigation. A touchscreen can use several methods to sense our finger, it can use a grid which consists of infrared beams or it can use touch sensitive units to sense our gestures.
With touchscreen, there are several gestures that we can make which would be quite tiresome if we use a mouse or a keyboard like when we double tap the screen while using gallery or while reading a pdf file the screen tends to zoom in and when we double tap again it zooms out similarly we can easily drag different icons and swipe to scroll upwards, downwards even sideways. A touch screen is also referred to as an input device as it takes input directly from the user. The computers require a mouse which makes them hard to use but touchscreen is very simple to use as you are directly interacting with the icons, it is also cost efficient to manufacture touchscreen as it does not require buttons for each icon.
In conclusion it can be said that LCD and Touch Screen have very different functions which makes them different from each other. One deals with production of images and the other deals with receiving the input from the user directly. Although they are different, they are equally important for a digital device.
Touchscreen devices consist of numerous different components that must work cohesively together in order to make it functional. The touch sensor, controller, and the software all play important roles. But there’s one component that’s often overlooked in the equation and that’s the touchscreen digitizer. This is the component that allows users to directly interact with what’s on the screen and issue commands.
As you know, touchscreen devices consist of multiple layers each of which serve a different purpose and carry out various functions. The purpose of the touchscreen digitizer glass layer is essentially to translate or convert physical touch commands into digital signals that the device can understand and then carry out.
Commercial and industrial displays such as capacitive and resistive screens all feature touchscreen digitizers that are placed on top of and connected to the LCD layer using a flex cable. While the LCD layer is responsible for displaying sharp and crystal-clear images on the screen, the LCD touchscreen digitizer reads, understands, and translates the commands given so that the device can perform the appropriate functions.
Touchscreen digitizers are fairly common components of modern LCD displays, but not all of them are equipped with one. The sole purpose of an LCD display touchscreen digitizer is to convert touch commands on the top layer into digital data that the device can understand and perform. Once the touch commands are converted into digital data, the device can then perform the required function and change the images displayed on the screen accordingly.
Touchscreen digitizers are made of a single glass layer, which means they can be susceptible to damage if the device is dropped or comes into contact with a brute force. Although the device can still marginally function depending on the extent of the damage to the touchscreen digitizer glass, its functionality and ability to comprehend touch commands may be limited. If the glass is completely shattered, then the device won’t be able to interpret touch commands at all.
The LCD and touchscreen digitizer layers of a device display serve completely different functions, but they work in tandem to maximize user experience and device performance. Since both of these components are made of thin glass layers, they’re not impervious to damages such as cracks or scratches as a result of being dropped or coming into contact with external physical stressors.
If it’s only the touchscreen digitizer that’s broken, you’ll still be able to make out what’s being displayed on the screen by the LCD component for the most part. The only difference is that parts of the screen or the entire screen might be unresponsive to your touch commands as a result of the damages. Moreover, blobs or splotchy images may appear in certain parts of the screen.
This indicates that there’s a disconnection between the touchscreen digitizer and the LCD display, which is preventing the device from performing the desired functions issued by touch commands.
The LCD screen is responsible for the visual component of your device. Pixelation in the form of multicoloured splotches or dots throughout the screen indicates that the LCD component has sustained a certain level of damage. It can be caused by wear and tear over time or if your device sustains physical damage.
A black screen indicates that the LCD layer of the device is damaged. The device itself will most likely still turn on and function like normal, but you won’t be able to see what it’s doing on the screen itself. Typically, this just means that the LCD layer needs to be repaired or replaced. Depending on the extent of the damage, it might be more practical and cost-effective to simply purchase a new device altogether unless you’re still within the warranty period.
The easiest repair for mobile phones to complete is the LCD assembly replacement. This repair takes less than an hour and requires the least amount of technical ability. For some devices the LCD assembly can be replaced simply by removing a few screws and cables. Also, as the assembly includes the glass, touch screen and the LCD, you can be confident it will fix all common screen issues.
For iPad and other tablets, if the screen parts aren"t fused, then you can do a glass touch digitizer only replacement. Otherwise, the full assembly is the easiest repair. Either way, it usually takes 1-2 hours.
While it can be significantly cheaper repair, If the screen parts are fused, the screens must be heated to loosen the adhesive between the screen and LCD and you need special equipment. This includes all iPhone and most other mobile phones and some iPads or tablets. A heat gun or hair dryer can be used for this. The screen is then gently and very slowly pried apart from LCD. DIYers need to use care to insure the LCD is not damaged in the process.
Tip: Transferring the home button on an iPhone or an iPad can be the most tricky part. It takes a little patience and heat. You can purchase screens that have the home button pre-installed (along with other small parts) and this is the easiest of all repair. This can take 15-30 minutes. However, Touch ID function only works with the original home button so you have to transfer if you want to retain it. Note: some of the iPads don"t have a screen replacement option that includes the home button like the iPad Pro and newer iPad Mini. iPad 1st Gen to 9th Gen screens, have a home button pre-installed option.
As an official phone repair provider who has been in the business for almost a decade, one unique question people ask when they visit our service centres to replace their phone screen is: "what"s the difference between original and copy phone screen?"
Well, the answer is, there are many differences between these two screens, which is mostly in their quality. And while “copy” phone screens are somewhat cheaper than the originals, it doesn’t justify the difference in quality. So, before you regret replacing your phone screen with a forbidden part, the tips below will tell you the critical differences between original and copy phone screens.
Generally, phone screens manufactured from your brand"s factory are the original ones while ‘Copy’screens are the ones designed and produced by third-party manufacturers and factories that are not related to your brand.
Many people usually like to go for copy screens because of their cheaper price. However, the "real" differences between original and copy screens lie in their quality, and here’s what you need to know about them.
One of the principal issues with "copied" phone screens and why it differs from the originals is touch and digitizer problems. And that"s a big problem since you"re going to control the device with the touchscreen anyway.
As far as we could remember, phone manufacturers build the touch panel/digitizer with the LCD itself, while the copied screen manufacturer build it separately on the surface glass. Hence, there"s a difference in touch sensitivity. Additionally, copied phone screens usually drop the high touch sampling rate, meaning your screen may not respond to your touches faster.
Here"s also another major issue with the digitizer on copied phone screens. When you crack a copied screen accidentally, the touchscreen stops working, stopping you from accessing the device until you fix it again. Meanwhile, the touch on the original phone screen works perfectly, even after undergoing severe cracking.
Besides having touch problems, most copy phone screens usually have poor display properties. That means you get lower brightness, colour accuracy, sharpness, contrast, etc. And when the display isn"t great, watching movies and viewing other content becomes boring.
For instance, if the original screen is supposed to have 480 nits of brightness, but the copy screen has just 200 nits, the screen becomes unusable under bright lights. Moreso, copied phone screen seems to have more blue light, which, in return, affect your sight and disrupts your sleep at night.
Among others, copied phone screens drop higher refresh rates, and that"s a bummer since most phones come with at least 90Hz refresh rate screens. What that means is the copied screen won’t feel smooth as it’s supposed to be.
It"s not all about the display quality. A copy phone screen may also affect other parts of the phone system if its specifications don"t tally with the original one. In such a case, it could drain your battery at an alarming rate, or at worse, damage your backlight.
If you happen to have a phone with an in-display fingerprint sensor, then replacing its screen with a copied one is not an option – it’s going to mess with your fingerprint accuracy.
We know copied phone screens for their poor quality, and it also extends to the fingerprint sensor. Hence, it takes a longer time to unlock your device. And in other cases, the security of the sensor is not accurate. We"ve seen situations where phones get unlocked with many unregistered fingers after replacing the screen with a copied one.
If you care about your phone"s security and you don"t want a sluggish fingerprint sensor, then we recommend you only go for the original phone screen replacement.
That brings us to the last difference we’re going to mention between copied and original phone screens. They manufacture copied phone screens with poor glass materials. Hence, they break quicker than the originals. And when they do, you’ll be left with only one option: to replace the screen again.
The major reason for choosing the official service centre over third-party/local repair shops summarizes what we"ve said earlier. The official service centre is the reliable place to get original phone screen replacement parts.
Besides offering you the original screen spare parts, the official service centres also have other advantages. These include certified and well-experienced technicians to fix the screen, the use of modern tools that won"t damage your phone further, and most importantly, a reliable warranty. Local repair shops usually don"t offer these features; most especially a reliable warranty, which means you"re on your own if the replaced screen gets faulty afterwards.
As far as choosing the official service centre is concerned for genuine screen replacement, then you shouldn"t shy away from Carlcare Service if you own a TECNO, Infinix, or itel phone with a cracked screen.
We"re the official service center for these three brands to cater for your mobile repair needs. And for screen replacement, Carlcare delivers excellently. Our brand-trained technicians replace your cracked screen with genuine OEM parts at affordable rates.

However, if the digitizer or LCD is also damaged during a fall, that screen no longer carries value because it cannot be refurbished. Repair shops cannot sell broken LCDs to refurbishing companies; therefore, they cannot offset the cost of an LCD repair. That is why repair stores often charge a little extra if there is damage to the LCD or digitizer, to make up for that loss. Repair stores that don’t have an additional charge for an LCD repair typically inflate their glass repair price to make up for the loss from damaged LCDs. If they have one price, that means everyone is paying more to cover the cost of customers who have damaged LCDs and customers who only have cracked glass. This is why TCR separates the price of glass and LCD repairs for you! If you only have cracked glass, you only have to worry about paying to replace the cracked glass.
If your phone or tablet’s glass is shattered there will be cracks or chips on the screen itself. If it is just the glass that is damaged, the device may still function and you may be able to use it normally. If this is the case, it is likely that only the glass needs to be replaced. To prevent further damage to your device it is best to get it repaired quickly. For example, if liquids seep through the cracks it could cause permanent damage to the LCD.
Many people may continue to use their touchscreen with shattered glass and delay fixing the glass on their devices; however, if the touchscreen isn’t responsive, it could be a sign of more significant damage to the device’s digitizer which is integrated with the LCD screen.
A pixelated screen can indicate LCD damage. This would look like a patch of multicolored dots, a line or lines of discoloration, or a screen with rainbow colors. For many people, these colors are an easy way to know that their LCD is broken and that they should get it repaired.
Dropping your phone isn’t the only reason you’ll end up with a pixelated screen. Over time, your screen’s LCD may break down through regular use. This happens to other devices aside from your smartphone or tablet. Pixelation can happen to TVs and computers, too. People typically decide to buy a new device when this happens. Fortunately, with an LCD repair, you can fix the device without needing to replace it.
A black screen or black spots on your smartphone or tablet is an indication of a damaged LCD. Often with a bad LCD, a phone may still turn on and make noises, but there is no clear picture. This does not necessarily mean any other part of the phone is damaged and a simple screen replacement will get it functioning again. Sometimes it can mean a battery or other internal component is damaged. It is best to have a highly qualified phone repair technician diagnose what is wrong so the appropriate repair can be made.
Fortunately, your mobile device is fixable whether you cracked the glass or damaged the LCD. Stop by or call TCR: Triangle Cellular Repair at (919) 263-2699 for a free diagnostic and quick, affordable cell phone repair in Chapel Hill and surrounding areas. We’re always happy to help!
“Original” screens are those containing LCDs manufactured for Apple. “Copy” screens are compatible replacements entirely designed and manufactured by third-party companies not associated with Apple.
LCD display panel can have poorer resolution (i.e. looks “coarser”), worse brightness, contrast and vibrancy and reduced refresh rate amongst other problems.
Changes in specification from original can result in battery and performance issues. Certain badly-engineered screens could even damage the backlight circuitry.
Customers who bring their iPhones to us for a screen repair are offered two choices of replacement- an original or a “copy” screen. The most common response is “Is there a difference- and which one would you recommend?”
Originals are those screens containing LCDs that were manufactured for Apple. So-called “copy” screens are compatible replacements, but designed and manufactured entirely independently by third-party companies, typically in China.
Our answer is simple- the original screen is the one we’d go for ourselves, every time. Some people think we make more money on them, but this isn’t the case. We recommend originals because they’re far higher quality and the price difference is fairly small.
We’d rather only fit original screens. The only reason we don’t is that many people will shop around and choose purely on price. As such, we need to offer the cheaper copy screens to remain competitive and avoid losing these customers. In some cases, they didn’t even know there was a difference in the first place- especially since it’s not in some shops’ interest to draw people’s attention to the issue!
This may well be the worst copy screen we’ve ever come across. As a result, the unfortunate customer has ended up paying twice to have their screen replaced- we’re sure that had they been properly informed, they would have chosen an original in the first place.
While the difference in price between copies and originals can vary across devices, it’s generally around £10 – £14 extra to have an original screen fitted. This really isn’t a lot considering the improved quality and reliability.
We compare our prices to our competitors- and we know that we come out of it favourably. While we have to offer copy screens to remain competitive, we always advise customers to go for the original.
When you’ve spent- directly or indirectly- several hundred pounds for an iPhone with a Retina display, it doesn’t make sense to replace it with a lower-quality screen that can make a £400 phone look like a £40 one! Not only that, but you’re likely to have fewer issues, and a longer-lasting screen.
Many- if not most- don’t even acknowledge the existence of copy screens, let alone explain the difference to the customer. Hardly in their interest to do so if they only fit cheap, low-quality copies. Some of them can hardly be blamed- they know so little, they’re not even clear on the differences between OEM, non-OEM and copy displays themselves! Others can be more deliberately misleading… and some outright lie.
Generally, these shops are looking for the cheapest price on replacement screens.. When offered a copy at a half or a third of a price of the original, they’re going to go for that. That might be fine if they offered the customer a cheaper price- what we disagree with is selling “supermarket beans” (i.e. the copy screens) at “Heinz beans” prices!
Heading towards the “blatantly fraudulent”, we’re aware of companies that shamelessly fit copy screens while claiming them to be original. Worse, they’ll take your broken original screen and sell that to a recycler for more than they paid for your copy!
Apple tightened up their supply chain around 2015, which reduced the number of screens available for repairs and increased their price dramatically. A lot of companies went bankrupt, and Chinese manufacturers responded by making their own “copy” screens from scratch. At first, these weren’t much cheaper than the Apple ones, but the price soon fell.
We should be clear that- despite the name- “copy” screens aren’t direct copies of the Apple originals. Rather, they’re compatible replacements that have been designed from scratch and- as a result- vary in some respects that have an effect on usability and quality.
One of the most important differences between an original and a “copy” screen is how the digitizer (touch sensor) is designed. Apple has it manufactured as part of the LCD itself, whereas the copies have it on the glass.
Although there are only a small number of manufacturers of the bare LCDs themselves, these are then bought by countless other companies who add the remaining components needed to turn these into a complete working screen. As a result, you could easily end up with an LCD from the best “copy” manufacturer, but the digitizer/touch (as part of the separately-manufactured glass) from the worst.
There are countless digitizers out there, and you can only take the supplier’s word that the quality is good. Many ship good ones at first, then switch to cheaper parts to make more profit. This is particularly bad with the iPhone 6S and 6S+, since Apple moved the chips responsible for touch processing onto the LCD itself. As a result, you’re not just getting a copy screen- you’re getting copy chips too.
The performance specification (power drain, etc.) of most copy screens isn’t identical to the originals. As a result, they can drain the battery more quickly and mislead the operating system which was optimised for the original screen design.
It’s even possible that this mismatch could damage your backlight. We do a lot of subcontracted repairs for less-experienced shops, and get backlight repairs in almost every day. We’ve had cases where we fixed the circuit, fitted the new copy screen to test it, and had it break the circuit again!
Copy screens can disrupt the touch ID fingerprint reader. With the 6S, 6S+, 7 and 7+, the home button- part of the 3D touch- is part of the screen assembly. Frequently the home button flexes on aftermarket designs don’t work properly and stop the touch ID working- annoying if you use it to unlock the phone or log in to your bank.
We’ve seen many lift away from the frame that holds them in place. This usually results in the flex cable getting torn, and the screen needing replacing. You don’t even need to have dropped the phone- this often happens through general everyday wear and tear.
That brings us to another major issue with the copies. When you drop an Apple original, the glass often breaks, but if the LCD itself is intact, you can continue to use it until it’s fixed. With the copies, the touch/digitizer is on the glass and stops working when that’s broken. Even worse, the LCD itself is more likely to break due to the thinner and more fragile glass.
We’re not convinced this will happen, since Apple recently changed their repair policy to accept iPhones with third-party screens. However, it is possible that copy screens could be stopped from working via an iOS update, since those make a number of security checks.
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.
