The market for LED TVs is diverse, offering various models with different features which can make selecting your preferred one difficult.

The main points that distinguish these LEDs from each other are their performance, functionality, and compatibility with different applications. Note and understand the different types of touchscreen LEDs and see which one works best for you.

• Resistive touchscreen LEDs

These televisions have a resistive panel to sense and follow commands when the screen is touched. They are made up of numerous layers. However, two of these are conspicuous and separated by a gap. They sense commands when these layers come into contact because of applied pressure.

Features

 

Resistive touchscreens are triggered by pressure. The touch screen sensors make use of pressure-sensitive analog switch technology. Consisting of two conductive-coated layers that face each other and are separated by a layer of small dielectric spacer dots. When you apply pressure to the upper surface, the two layers make contact, allowing the controller to determine the touch point.

Applications

These touchscreen LEDs are found in advertisements and anywhere customers use interactive information, such as placing orders at restaurants or banks.

• Infrared (IR) Touch Screen LEDs

Unlike resistive touchscreen LEDs, these LEDs detect touch using infrared sensors. This type of LED has a bezel around the screen that produces infrared light. When it meets touch the sensors detect it.

Features

These LEDs consist of an infrared grid above the screen surface. When anything meets this surface an action is detected.

These LEDs have a multitouch feature which allows multiple touches to be detected at one time. This is what makes these LEDs stand out from the rest. Infrared touch screens can be used in various lighting conditions and are mostly used for large-scale purposes.

Applications

Infrared touch screen LEDs are used in more collaborative settings, such as interactive stalls and educational settings.

• Surface Acoustic Wave (SAW) touchscreen LEDs

Surface acoustic wave touchscreen LEDs function by interrupting ultrasonic waves that travel over their surfaces. Any touch disrupts this wave, which detects the touch position.

Waves are sent to the transmitting transducers that move along the panel’s edge. The edges of the panel consist of reflectors that shift the direction of the SAWs at a 90-degree angle, allowing the SAWs to pass across the panel. Once they’re on the opposite side, their trajectories are modified again by the reflectors, and they proceed toward the receiving transducers. Once the receiving transducers detect the SAWs, they are transformed into electrical signals.

Features

The single glass layers of these LEDs allow good light transmission. This gives us excellent visibility. The glass surface of these LEDs is scratch resistant which increases durability. However, if by any chance the screen gets scratched, the sensing technology will still work.

The screen and sensing technology of this LED is top-notch because it does not get affected by any environmental conditions. Thus, maintaining its performance under any situation. However, we need to keep it away from water or any sort of liquid because it can cause the screen to malfunction.

Applications

These displays are commonly used in industrial control panels because they provide excellent image quality, allow multi-touch, and are very durable.

• Capacitate touchscreen LEDs

These LEDs make use of the electrical capacities that we possess to function. They consist of a glass layer that is made up of a conductive coating that is responsive to touch.

This electrical touch detection makes it very sensitive to touch and supports multi-touch technology. These aspects enhance accuracy and screen responsiveness.

Features

Capacitive touch technology uses the electrical qualities of a person as an electrical conductor to determine the contact point. It also supports multitouch which allows up to ten different touch detections. These LEDS feature a glass surface that allows these electrical waves to pass through.

Applications

These LEDs are commonly used for commercial or industrial purposes that require multiple interactions at the same time.
