A capacitive touch screen is a control display that uses the conductive touch of a human finger or a specialized device for input. Input to resistive touch screens works through pressure resulting in two conductive layers being pressed together.
When a capacitive panel is touched, a small amount of charge is drawn to the point of contact, which becomes a functional capacitor. The change in the electrostatic field is measured to find the location. In some designs, circuits located at each corner of the panel measure the charge and send the information to the controller for processing. In multi-touch screens, sensors are arranged in a grid to enable more complex input.
Unlike resistive and surface wave panels, which can sense input from either fingers or simple styluses, capacitive touch screen panels must be touched with a finger or a special capacitive pen or glove. The panel is coated with a material that can store electrical charges and the location of touch to the screen is signaled by the change in capacitance in that location.
Input to resistive touch screens works through pressure resulting in two conductive layers being pressed together. In comparison, capacitive touch screens are not affected by outside elements, have high clarity and allow for easier functioning with lighter contact and greater accuracy.
Many current smart phones, tablets and other mobile devices rely on capacitive touch, including Android phones and Microsoft Surface, as well as iPhone, iPad and iPod Touch.
Capacitive touch panels are more often used for big surfaces, as they need less accuracy. Capacitive technology advantages are: Excellent sensitivity; Multi-touch capability;Very good durability with glass front designs.

Interactive flat panel display are exactly what they sound like—displays that you can interact with, similar to a smart phone screen, but much larger.
This article will introduce IQBoard interactive flat panel new series - IQTouch X Series - Capacitive interactive flat panel.
As an ideal solution to education and business, IQTouch X series uses capacitive touch technology, which can respond without delay and operate directly. It features 20-point touch that enables several users working on the screen at the same time. 4K crystal clear display delivers the highest image quality. Built-in wireless screen projection software allow Android, IOS, Windows to cast screen on IQTouch X quickly.
Capacitive is the leading type of touchscreen technology. With capacitive touchscreens, a uniform electrostatic charge is applied to the top layer. Because the human body is conducts electricity, touching the display will absorb some of this current, which the devices uses to detect touch commands. For touch accuracy, capacitive is typically more accurate than other touch technology. Touching the display of a capacitive device will absorb electrostatic current from that specific area, allowing for a superior level of accuracy.
Advantages: IQTouch capacitive interactive flat panel has dual operation system: Android 8.0 and Windows 10 Pro. With capacitive touch, it has fast response, and it supports 20-point touch and 4K UHD Display, fully compatible with Windows, Mac, & Chromebook.

The technology behind interactive touch screens is continually evolving. Alongside points of touch, use of software and others, a significant development is from infrared touch to use of capacitive touch technology.
Learning the differences and benefits between Infrared touch technology and Capacitive touch technology, which will help you to choose the perfect touchscreen for you.
Capacitive is the leading type of touchscreen technology. Even if you’re unfamiliar with it, you’ve probably used - or still use - a capacitive touchscreen device. From smart phones and tablets to video game consoles and smart appliances, countless touchscreen devices are powered by capacitive technology. Infrared touchscreens aren’t as common as their capacitive counterparts, but they are still worth considering if you are looking to buy one or more touchscreens. Infrared touch technology is gaining momentum these days.
With capacitive touchscreens, a uniform electrostatic charge is applied to the top layer. Because the human body is conducts electricity, touching the display will absorb some of this current, which the devices uses to detect touch commands.
The sensitivity and accuracy of this technology is greater. The glass on the screen is highly durable because of its need to stay in good condition as that is how it registers touch. You can be happy in the knowledge that it stays tough in the roughest classroom.
Infrared touch screens don’t use an electrostatic charge to detect touch commands. Instead, they use a combination of light-emitting diodes (LEDs) and sensors to detect touch commands. IR touchscreens are designed with LEDs that emit light to corresponding sensors across the surface of the display. If you touch the display, you’ll disrupt the LED light in that area, which the device uses to detect your touch command.
The technology involves an embedded overlay of infrared beams all around the screen from a strip within the device’s bezel. When an object interacts, a finger or a stylus for example, the device will register it as a touch point.
IR and capacitive are two completely different types of touchscreen technology. IR uses a grid-like array of LEDs and sensors to detect touch commands, whereas capacitive uses a uniform electrostatic current to detect touch commands.
An interactive touch screen facilitates an immersive learning experience, making education fun for both students and teachers...... Interactive touch screen is both simple and intuitive, providing teachers with the latest and most responsive interactive screen technology to support active and inspired learning. This article will talk about IQTouch interactive touch screen series of 86’’.
Of all of our IQTouch interactive screens, IQTouch 86’’ interactive touchscreen (218 cm diagonally) is the biggest, the most powerful. It is optimized for school use. An interactive screen of 86’’ well placed in a class of 35 students will be read by 100% of students with a normal eyesight (97% in a class of 40 students). This screen size is therefore the most suitable for classroom use, replacing the interactive whiteboard.
Like the whole range of IQTouch interactive touch screen series, IQTouch 86″ interactive screens come with an Android core that makes all tasks more intuitive and easier and more complete. The touch screen is a giant Android tablet that starts almost instantly, you have access in seconds to the Android interface. You will find the gestures you know on your tablets or smart phones, as well as the essential applications. The toolbar is accessible at all times and on all sources, simply by clicking on the button on the sides of the screen. It allows you to annotate any screen, take a screenshot, create slides for your presentations and browse your pages.
IQTouch 86’’ interactive screens have IQ Interactive Education Platform software. For all your lessons, the IQ Interactive Education Platform software for interactive screens brings you numerous tools and digital resources, in science subjects (maths, physics, chemistry) or in English. Create rich and dynamic presentations, adapted to your field of teaching.
In a class of 40 students where an interactive screen is potentially used 100% of the time, it is very important that all students can see the picture on the interactive screen perfectly regardless of their position in the room. Our IQTouch 86’’ interactive screen features the new IPS technology, which retains the best color quality when we view the interactive screen from an angle (up to 178 degree angle) without trail effect and color distortion.
Like all the screens in the IQTouch range, the 86’’ interactive screen has a timer (programmable) that automatically puts the screen in standby mode when idle. In standby mode, the power consumption is less than 0.3 W.
The IQTouch 86’’ interactive screen is also available in ultra-high definition (UHD, 3840 x 2160 pixels) resolution, four times the quality of Full HD interactive screens (1920 x 1080 pixels). The resulting image is of exceptional quality. It is even thinner and readable.
Thanks to OPS technology, our interactive screens can be delivered with a PC integrated in the edge of the screen. The screen becomes intelligent and completely autonomous under Windows, no cable is needed.
Educational technology represents a big investment for schools -- so it makes sense to do your research before you buy. We can help set up some purchasing guidelines to help drive your decision. Here’s our top tips for buying the best interactive panels for your classroom.
This is the first question that you should address before you begin making your purchasing decision. However, it’s not as simple as it first appears. Many schools opt for the device with the lowest possible price per unit—but this approach can be short-sighted.
Lower-priced devices often have associated costs, such as software licensing fees, repair and replacement costs, and IT support, that drive up the total cost of ownership. IQTouch interactive touch screen has software bonus for each touch screen order.
Flat panel interactive displays which are suitable for most classroom sizes range from 55” to 98”, with the most popular sizes being in the range 65” to 84”. The size of the room should dictate the size of your screen. The basic rule is that the screen should be large enough to allow the students at the back of the class to be able to easily read a 20pt font.
The resolution defines the sharpness and clarity of any visual panel and is the number of pixels (individual points of colour) contained within the screen. The resolution is defined as the number of pixels in the horizontal axis X the number in the vertical axis. The higher the resolution, the sharper and crisper the image. For example, IQTouch interactive touch screen series are all with clear 4K UHD display.
4. Students Age
This is an important question to ask because it highlights the functionality your students need in their classroom technology. Younger students, for instance, typically do better with tablet-style devices with touch screens that help build their manual dexterity while Junior High and High School students tend to need more functionality than tablets offer and do better with laptops or desktop devices. Fortunately, IQTouch touch screen series offer multiple connectivity, including mobile connectivity, and feature 10 or 20 simultaneous points of touch so that students can collaborate more easily.
There are other questions to consider before investing in educational technology for your school--How often do you plan to upgrade? Which operating system do you want your students to learn? but these initial 4 suggestions will get you a long way toward a smart decision.
