Capacitive multi-touch screen: definition and features

Capacitive multi-touch screen: definition and features

The screens of modern devices can not only display an image, but also allow you to interact with the device through sensors.

Initially, touch screens were used in some pocket computers, but today touch screens are widely used in mobile devices Smart Film Thailand, players, photo and video cameras, information kiosks, and so on. At the same time, each of the listed devices can use one or another type of touch screen. Currently, several types of touch panels have been developed, and, accordingly, each of them has its own advantages and disadvantages. In this article, what types of touch screens is just considered, their advantages and disadvantages, which type of touch screen is better.

There are four main types of touchscreens: resistive, capacitive, surface-acoustic, and infrared. In mobile devices, only two are most widespread: resistive and capacitive. Their main difference is the fact that resistive screens recognize pressing, and capacitive ones – touch.

How Do Touch Screens Work on Laptops and Tablets?

Resistive touch screens

This technology is most widespread among mobile devices, due to the simplicity of the technology and low production costs. A resistive screen is an LCD display on which two transparent plates are superimposed, separated by a dielectric layer. The upper plate is flexible film กระจก, as the user presses on it, while the lower one is rigidly fixed to the screen. Conductors are applied to the surfaces facing each other.

The microcontroller applies voltage in series to the electrodes of the top and bottom plates. When the screen is pressed, the flexible top layer bends and its inner conductive surface touches the bottom conductive layer, thereby changing the resistance of the entire system. The change in resistance is recorded by the microcontroller and thus the coordinates of the touch point are determined.

The advantages of resistive screens include simplicity and low cost, good sensitivity, as well as the ability to press the screen with your finger or any object. Of the minuses, it is necessary to note poor light transmission (as a result, you have to use a brighter backlight), poor support for multiple clicks (multi touch screen impact), they cannot determine the pressing force, as well as rather rapid mechanical wear, although in comparison with the life of the phone, this drawback is not so important, as the phone usually fails faster than the touchscreen.

TOUCH SCREEN TECHNOLOGY (One Touch, Open up World) – SAE-NITK

Infrared touch screens

The design and operation of infrared touch screens is quite simple. Along the two adjacent sides of the touchscreen are leds that emit infrared rays. And on the opposite side of the screen are phototransistors that receive infrared rays. Thus, the entire screen is covered with an invisible grid of intersecting infrared rays, and if you touch the screen with your finger, the rays overlap and do not hit the phototransistors, which is immediately registered by the controller, and thus the coordinates of the touch are determined.

Resistive screens

In simple terms, avoiding wise technical terms and phrases, a resistive touch screen is a flexible transparent membrane, on which a conductive (in other words, resistive) coating is applied. Under the membrane is glass, also covered with a conductive layer. The principle of operation of a resistive screen is that when you press the screen with your finger or stylus, the glass closes.

So how is the Internet of Things revolutionizing retail digital signage?

Obtaining information through data

One of the most exciting ways that retail digital signage has been revolutionized through the introduction of IoT technologies is the use of awareness systems to learn about customers and their decision-making processes. 

Thanks to built-in recognition systems, retail digital signage can now determine the gender and age of a customer, as well as whether they have visited that specific store before, a capability that is now being used, for example, in programs loyalty.

Finding out which areas of a store receive the most foot traffic and determining which products would be of most interest to a customer based on their gender and age range are other ways to use the data produced by IoT-powered digital signage.

However, security will be an important factor in whether or not to accept the use of data to create such retail experiences, and it will be necessary for retailers to make efforts to reassure customers that their data is correct. There is also the alternative of “opt-in” scenarios, in which customers would accept the store’s requirements, although these are often less desirable.

Astronauts Enter China’s Space Station For The First Time

The amount of information and knowledge we can obtain from space is simply unimaginable. When we think of the Space Station, or anything that involves space and off-Earth missions, the first country that comes to mind is the United States.

However, China is investing heavily in its space program. And it’s no surprise that China has been increasingly ambitious. Now, the first astronauts have arrived at China’s new space station. That feat was on the longest crewed mission in the country to date. This was a very important step in establishing Beijing as a space power.

Spacial station

The trio of astronauts took off on the Long March-2F rocket from the Jiuquan launch center in the Gobi Desert of northwestern China . After approximately seven hours the ship docked at Tiangong station. Astronauts will spend the next few days on it.

Chinese state broadcaster CCTV showed a live broadcast from inside the spacecraft during the trip with the three astronauts. One of them smiled and waved at the camera after the ship reached orbit,

The Shenzhou-12 spacecraft separated from the Long March rocket and “successfully docked at the forward port of the Tiangong station’s central module,” according to the China Manned Space Agency.

Astronauts were shown entering the central module. And one of them did a 360 degree turn as it entered. The trio of astronauts settled into their quarters and opened the cargo door to Tianzhou-2 on Friday morning.

Mission commander Nie Haisheng is a decorated People’s Liberation Army Air Force pilot who has participated in two space missions. And the other two mission members are also military.

Astronauts

The space station’s central module has two separate spaces for each astronaut, a space treadmill and bicycle for them to exercise, and a communication center for email and video calls with ground control.

According to Huang Weifen of China’s Manned Space Program, the astronauts would take two spacewalks during the mission. The two would last six or seven hours. In addition, he also said that the trio of astronauts would wear newly developed spacewalking suits.

This launch of China’s first manned mission in nearly five years is a matter of enormous prestige as Beijing prepares to mark the 100th anniversary of the ruling Communist Party on July 1st.

The Chinese space agency’s future plans are 11 launches by the end of next year. Among them, three manned missions that will deliver two laboratory modules to expand the station.
