Shenzhen touch screen

Types of Shenzhen touch screens

A Shenzhen touch screen comes in several types, including resistive, capacitive, and surface acoustic wave (SAW) models. Each type has unique characteristics, functionalities, and applications.

• Resistive touch screens

  Resistive touch screens are made of two thin, flexible layers of transparent materials. These layers have an air gap or thin-film adhesive between them, ensuring they don't touch each other. The outer layer is harder and scratched-resistant, while the inner layer is softer and more flexible. When a user touches the screen, the outer layer bends, making the two layers touch at the point of contact. This touching point is then detected by the system. Resistive touchscreens can only be used with a stylus pen, gloved hand, or soft object.

• Capacitive touch screens

  A capacitive touch screen is made of glass layers coated with a transparent conductor such as indium tin oxide (ITO). The screen has an electrostatic field on the surface. When a user's finger gets close to the screen, it disrupts the electrostatic field. The change in capacitance at that point is detected and converted into a touch command. Capacitive touch screens can only be operated by the bare human finger or a conductive stylus pen.

• Surface acoustic wave (SAW) touch screens

  Surface acoustic wave touch screens have an array of ultrasonic waves on the surface. When a user touches the screen, the waves are absorbed, and the point of contact is detected. This touch screen is made of glass and is highly transparent. It can be operated with a finger, pen, or stylus. This type of touch screen is highly durable and reliable.

Functions and features of Shenzhen touch screen

Shenzhen touch screen manufacturers design screens with a wide range of functions and features. They include the following;

• Analog Resistive Touch Screen: It consists of two flexible layers made from a resistive material that is coated with a transparent conducting layer. Only one layer is movable and touchable. When the top layer is compressed, it touches the bottom layer, allowing the user to press anywhere on the screen. This screen works with any pointing equipment and costs less than others. However, it can take longer to assemble and may not be as sturdy.
• Capacitive Touch Screen: It has a glass panel that stores electrostatic charge on its surface. When a person touches the screen with their finger, the charge is diverted, allowing the system to pinpoint the exact location of the touch. It is more sensitive, supports multi-touch, and is easier to operate. Direct and capacitive touch technology can be integrated into the screen.
• Projected Capacitive Touch Screen: Capacitive technology can be combined with PCAP screens. They consist of a glass substrate with capacitive sensors, allowing users to operate the screen with bare hands, gloves, or stylus. It offers better transmittance and supports multi-touch gestures.
• UV Curing Adhesive Touch Screen: This screen is made when a UV adhesive is used to attach touch technology to a screen with a rigid glass substrate. The glue cures under UV lights, creating a robust bond. Manufacturers can make different types of touch screens using this technology. It is scratch-resistant and can be used in multi-modal applications.
• Optical Bonded Multi-Touch Touch Screen: The screen has precise sensors that allow multiple points to be touched simultaneously. Multi-touch screens enable various functions, like pinch zooming on images and maps, opening and closing applications, and viewing thumbnails. The multi-touch feature improves how the device is used.
• High Brightness Touch Screen: High brightness touch screens maintain brightness levels for images, data, or graphics, even in outdoor or high ambient light settings. The screen is visible under harsh lighting and works well in areas such as transportation hubs, healthcare, and industrial settings.
