The difference between wireless screen sharing, screen mirroring and screen casting


Can you imagine displaying your tablet or phone stuff to the big screen with a single click? This is possible if you heard about screen mirroring , casting and streaming functions. The functioning of these terms is different from each other.  


 It’s important to know that wireless interactions work differently, depending on what content you want to be shown and how you prefer to go about it. This article will talk about the basics of screen mirroring, screen casting (also known as media streaming) and screen sharing (also known as desktop sharing).


What does streaming mean? Maybe you’ve heard someone say that they streamed a movie, a podcast, or a slide show. Steaming means a continuous flow of information (in the form of visual and/or audio data). That is to say, steaming refers to deliver data live, whatever content you have on your device’s screen. With this in mind, take note that the three terms that follow—mirroring, casting, and sharing—are each a different way of streaming.


Screen mirroring allows you to project or mirror what is on your smart phone, tablet or computer and show it on your TV screen, projector, or external monitor without needing to use a cable. It’s unlike when we look into a glass mirror, screen mirroring won’t horizontally flip what you see. It’s more like copying. This is great for viewing local content such as pictures, videos, documents, and professional or educational presentations. Screen mirroring requires software running on the device you want to send content from, and a receiver on the display that you’re sending it to.


For example, screen mirroring are what you can do with AirPlay, which is Apple’s protocol that allows you to mirror the contents of your Mac, iPhone or iPad to a screen connected to an Apple TV.


The major difference between screen mirroring and screen casting is the way in which the content is shared to a display. In the case of screen casting, your TV wirelessly receives online content via a digital media player to a TV via a wireless connection. Screen casting uses an app to send movies, video clips, and music from your phone, tablet or computer to your TV screen. 


Screen sharing is also known as desktop sharing. While mirroring and casting are done with a smaller device (e.g., mobile or laptop) and a larger display (e.g. TV or projector), screen sharing generally involves making a copy of your computer screen to other computer screens.

You should know Capacitive Touch Display


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.

So, next time you’re starting a project about capacitive touch display, and you don’t know how to choose, check out this article. 

Interactive Flat Panel IQBoard Interactive Display Solutions


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.

Capacitive vs Infrared Interactive Display:Things you should know


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.

The Most Suitable Large-size Touch Screen for Classroom Use

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.

Guide to Buying Interactive Touch Screen for School


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.


1. Budget

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.


2. Size

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.


3. Resolution

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.  Or, if you are ready to see our panels in action, contact us for a no obligation on-site demo
