Touch screen panel

Types of touch screen panels

A touch screen panel is an input device that allows users to provide commands and control through the screen by touching it. It comprises a monitor and an overlay sensor that detects touch. Manufacturers design touch screen panels in various types, each with unique features to suit different applications.

• Capacitance touch screen panel

  The capacitive touch screen uses the capacitance effect to determine touch based on the change in capacitance. It has a glass substrate layered with a capacitance sensor and protective glass. The screen is durable and highly sensitive. Users with bare fingers can operate it in any weather condition. The quick response makes it ideal for mobile devices. However, a capacitive touch screen only works with a bare finger or conductive stylus. It cannot respond to a touch made with a glove or other body parts.

• Projected capacitive touch screen

  The projected capacitive touch screen is a duplication of the capacitive touch panel but with a different design and functionality. It consists of a grid of capacitors and electrodes and uses the capacitance moire effect. When a person touches the screen with a bare finger, a change in capacitance occurs, and the screen detects the touch. This type of touch screen is highly sensitive, thick gloves, and wet or dry fingers can operate it. Users can operate the touch screen with any body part or object. Projected capacitive touch screens work well with mobile devices, ATM machines, and gaming consoles.

• Infrared touchscreen

  An infrared touch screen has a layer of glass with a grid of infrared beams or light over it. When a person touches the screen, the beams break, and the sensors detect the touch. Infrared touch screens are very sensitive and can be operated with any body part or object. They are also very durable since there are no moving parts or layer over the glass. However, dust, dirt, or fingerprints can interfere with the infrared beams. Business outfits that use a touch screen in outdoor environments opt for this kind of touch screen.

• Surface acoustic wave (SAW) touch screen

  A surface acoustic wave touch screen has a glass panel with ultrasonic waves. When a user touches the screen, the waves on the surface of the screen disrupts, and the sensors detects the touch. This touch screen is easy to clean and highly sensitive. It responds to almost any disruption made on the surface, hence, suitable for embedding in shops, cafes, and airports. However, the SAW touch screen is sensitive to dust, dirt, and moisture.

• Resistance touch screen

  Manufacturers make the resistive touch screen with two flexible layers of plastic or glass, coated with a metallic film. When a person presses the screen, both layers flex and touch each other. Sensors then detect the touch. This design makes the resistive touch screen affordable compared to others. It allows one to operate the screen by pressing it with fingers, a stylus, or object. Unfortunately, multiple people cannot operate the screen at once because the pressure from one layer has to touch the second layer. Nonetheless, the resistive screen works well on navigation devices, old mobile phones, and simple monitors.

Function and features of touch screen panel

The touch screen panel plays a critical role in making reliable and seamless interactions between the user and the device. It has various features and functions that enhance this operation.

Functions

• Input Detection: The primary function of a touch screen panel is to detect and register input on the screen. This can come in different forms, such as touches, gestures, and swipes. The system translates these actions into commands that the software can recognize and respond to accordingly. A good example of this is the way a user can navigate through an application by simply swiping on the touch screen.
• Visual Display: A touch screen also functions as a display screen for the device, showing all the relevant visual information. This panel comes with high graphic capabilities that present crisp and clear images. Happy customers are likely to make more purchases when presented with visually appealing content. The screen is available in various resolutions and sizes to cater to different users' preferences. This feature allows users to comfortably view videos and images on the responsive screen.
• Durability: Touch screens are made for heavy daily use without wearing out or breaking. Different grades of strengthened glass protect the screen against scratches and impact.

Features

• Multi-Touch Support: A good number of modern touch screen panels come with multi-touch capabilities. It enables the simultaneous detection of multiple touches. This functionality allows complicated gestures like pinch-to-zoom and scrolling to be carried out. Users can interact with the panel intuitively. Enhanced capabilities improve accessibility and users can widely operate devices.
• Haptic Feedback: Some touch screen panels offer haptic feedback capabilities. A sensor vibrates lightly to give the user a response during touch-based interactions. The vibration features help enhance the overall experience by increasing the sense of control and accuracy.
• Glove/ Stylus Compatibility: Glove compatibility enables the touch screen to recognize input even when the user is wearing a glove. Such screens are mostly used in industrial settings or applications where hand protection is necessary. Also, some touch screens work well with stylus pens, offering precise input for tasks such as drawing or writing. This combination is mainly used in tablets and smartphones. However, it is important to note that not all touch screens work with stylus pens.
• Customizable Settings: Touch screen panels allow end users to customize various settings according to their unique preferences. Users can adjust the touch sensitivity, display brightness, and multi-touch gestures. Such modifications improve the overall experience and make the device more user-centric.

Usage scenarios of touch screen panels

Since a touch screen panel is a user-friendly input device with broad applicability, its usage spans various industries and sectors:

• Industrial controls: In manufacturing plants and oil refineries, durable touch panels are used for machine control, monitoring production, and doing tasks in workplaces with higher pressure environments such as factories or oil fields. Operators like the quick reaction and precise control of touch screens in these situations.
• Point of sale (POS): Retail shops and restaurants now use touch screens for checkout and ordering instead of conventional payment methods. This speeds up transactions and makes it easy for employees to respond to customers, which enhances the overall buying experience.
• Medical devices: Doctors and nurses use portable touch screen monitors to see vital signs and other patient information because they work better than conventional interfaces. This allows healthcare professionals to quickly and easily respond to critical situations and decreases response times in critical care.
• Consumer electronics: Touch screen computer monitors, tablets, and other devices that respondents use are examples of consumer electronic goods. They have completely changed the way users interact with these gadgets by making navigation easy and straightforward.
