What is touch frame?
The touch frame, also known as the infrared sensor frame helps to switch from the surface of conventional LCD, LED, projectors to the multi-touch plane, allowing you to control the screen with your finger instead of using a mouse or remote. Or to put it simply, the device turns ordinary tv into a modern touch TV, easy to use for all TVs.

What is infrared sensor frame? Infrared touch frame application.
Perhaps the concept of infrared touch is now too familiar in everyday life. Almost the most popular smart technology devices today such as smartphones, tablets, interactive screens, touch TVs, information lookup tables ... etc ... are equipped with infrared touch technology with series of different features.

However, each type of device will have its own touch technology with its own function and application.

One of the most popular and modern touch types today is infrared touch technology, with the ability to accurately detect the touch, easy to use and is applied with many different features.

We invite you to read together to learn more about the concept of infrared touch screen (IR touch) as well as the operations and benefits that this technology brings.

What is infrared sensor frame?

The infrared sensor frame is a screen frame covered on the surface by a dense horizontal and vertical infrared grid, which identifies the touch by determining the coordinates of the infrared intermittent on the plate. this grid. In a simple way, the screen frame will be surrounded by a frame containing a series of infrared LEDs (also known as touch frames or interactive frames) that project infrared rays that the naked eye cannot. visible in a horizontal and vertical layout like a net.

When the user touches the screen, the infrared rays will be interrupted by the finger and bounced back into the sensors arranged around the sensor frame, thereby detecting the interval coordinates and confirming touch position.

The key to the extremely high precision of the frame, the infrared touch screen is because the infrared rays are arranged horizontally and vertically with extremely dense density, from which the sensor can be easily detected. the coordinates of the interrupted points.

Moreover, unlike capacitive touch, when touch can only be detected from a human finger or a stylus, users can completely use their fingers, pencil, ballpoint pen or any other hard object to match. writing drawing on the screen surface.

The explanation for this is because capacitive touchscreens will determine touch based on the charge disturbance on the screen caused by an object with a touching charge (finger, stylus). Therefore, objects that are not charged will cause the sensors of this screen line to detect. As for the infrared screen, any hard object with the right size can interact with touch on the surface.

Application of infrared touch technology?
The most important component to make up an infrared sensor frame is the LED system mounted on the sensor frame around the screen border. This is a remarkable point coming from the structure of this screen with much more convenient features than touch screens on smartphones or tablets (capacitive touch). Because the capacitive touch screen line will often have to be equipped right from the original design of the panel, with a relatively high cost, expensive repair because when the screen is damaged, it is considered that the entire sensor will also. easy to spoil. And the infrared touch screen is different, because the touch frame is installed along the edge of the screen, so if the display screen is damaged, the infrared light frame will not be affected, even if there is detachable and re-integrated with another screen of the same size.

The infrared light frame above can also be split into a separate device called an intelligent interactive frame, which can turn a regular TV of the same size into an extremely touch screen. easily. The interactive frame can be easily combined with all different types of TV thanks to the installation of a navigation system, as well as very easy installation.

This interactive frame technology is also applied to a line of devices that are also quite prominent at the moment, which is an intelligent interactive panel with the outer border surrounded by the LED system mounted on the frame. However, this type of device is not purely a display device, as its principle of operation is to be combined with a projector and reflecting the projected image while also supporting touch-sensitive dots. Application from 4-10 touch points on the surface of the board instead of having to use the mouse and computer.

The most typical and prominent application of infrared touch screen technology is intelligent interactive screen, touch screen TV.

This is a series of integrated all-in-one devices to support presentations, presentations, and teaching as easy and optimized as possible.
