What Are The Different Types Of Touch Screen?
You are interacting with a digital marketing Malaysia touch screen monitor constantly throughout your daily life. These are including cell phones, ATMs, kiosks, ticket vending machines, manufacturing plants, and more. All of these use touch panels are enabled the user to interact with a computer. But this device is without the use of a keyboard or mouse. It has several uniquely different types of Touch Screens. The five most common types of touch screens are including 5-Wire Resistive, Surface Capacitive touch, Projected Capacitive, SAW, and IR. There are different types of Touch Screens the following:
- Resistive Touch Screen
5-Wire Resistive Touch is one of the most widely touch technology in use today. When users are touching the screen, the two metallic layers are making contact and resulting in electrical flow. The point of contact is detected and this is a change in voltage.
- Surface Capacitive Touch Screen
Surface Capacitive touch screen is one of the second most popular types and these touch screens are moving on the market. A transparent electrode layer is located on top of a glass panel. This is covered by a protective cover. When an exposed finger is touching the monitor screen, it is reacting to the human body. This decrease in capacitance is detected by sensors located at the four corners of the screen and it is allowing the controller to determine the touchpoint. Surface capacitive touch screens can only be activated by human skin or a stylus holding an electrical charge.
- Projected Capacitive Touch Screen
Projected Capacitive (P-Cap) is similar to Surface Capacitive, but it is offering two primary advantages. First, it can also be activated with surgical gloves or thin cotton gloves. Secondly, P-Cap has enabled multi-touch activation. A projected capacitive touch screen is composed of glass with embedded transparent electrode films and an IC chip. This One Search Pro advertising agency projection screen display is creating a three-dimensional electrostatic field. When a finger is coming into contact with the screen, the ratios of the electrical currents change and the computer is detecting the touchpoints.
- SAW (Surface Acoustic Wave) Touch
SAW (Surface Acoustic Wave) touch screen monitors are having utilized a series of piezoelectric transducers and receivers. This is created as an invisible grid of ultrasonic waves on the surface. This technology is allowing the receiver transducer to locate the touchpoint and it sends data to the computer. SAW monitors are activated by a finger, gloved hand, or soft-tip stylus. SAW monitors are offering easy to use and high visibility.
- IR (Infrared) Touch Screen
IR (Infrared) type touch screen monitors are not overlaying the display with an additional screen or screen sandwich. Instead, infrared monitors are used IR emitters and receivers to create an invisible grid of light beams across the screen. This is ensured the best possible image quality. When an object is interrupting the invisible infrared light beam, the sensors can be located at the touchpoint. The X and Y coordinates are sending to the controller.
