Multi-touch screen, also known as multi-touch technology, is a technology that allows the user to touch the surface of the screen at the same time using two or more different gestural media. This technology enables a variety of multi-touch applications such as picture zooming and rotation, and has all the features and advantages of a traditional single-point infrared touch screen. Multi-touch screen, especially the projected capacitive touch screen, through the multi-layer ITO layer to form a matrix distribution, X-axis, Y-axis cross-distribution as the capacitance matrix, when the finger touches the screen, can be detected through the scanning of the X, Y-axis changes in capacitance at the location of the touch, and then calculate the location of the finger contacts, thus realising multi-touch operation.
With the rapid development of artificial intelligence technology, touch screen technology is increasingly widely used in various fields. Multi-touch screen as an important branch of touch screen technology, its application prospects are also very broad. With the popularity of smart phones, tablet PCs, smart TVs and other devices, as well as the development of smart homes, smart cars and other emerging fields, multi-touch screen technology will continue to be upgraded to be more intelligent, humane and environmentally friendly. In the future, multi-touch screen is expected to achieve applications in more fields, such as flexible foldable screen, borderless screen, holographic projection screen and other new touch screen technology continues to emerge, will also bring new opportunities for the development of multi-touch screen.
Multi-touch screen has a wide range of applications, mainly including the following aspects:
1. Public information query: in libraries, museums, stations and other public places, multi-touch query software can provide an interactive query experience, users can slide their fingers on the screen, zoom, rotate and other ways to get a more intuitive and convenient information services.
2. Commercial display: In commercial display, multi-touch screen can be used to display products, introduce corporate image and other aspects to improve the display effect and audience experience.
3. digital media advertising: in digital media advertising, multi-touch screen can achieve the interactive display of advertisements, improve the attractiveness of advertisements and dissemination effect.
4. education and training: in the field of education and training, multi-touch screen can be used to produce interactive courseware, teaching video, etc., to improve the learning effect and participation.
5. Healthcare: In the field of healthcare, multi-touch screen can be used to display medical information, medical records, etc., to improve work efficiency and quality of medical services.
6. Intelligent Interactive Terminal: In the intelligent interactive terminal, multi-touch screen can be linked with other devices to achieve more intelligent human-computer interaction.
Compared with other input devices, multi-touch screen has the following advantages:
1. Convenience of operation: Multi-touch screen allows multiple fingers or media to be operated at the same time, and the user can perform multi-point simultaneous operation on an interface, which improves the convenience and flexibility of operation.
2. Rich control mode: multi-touch technology enriches the user's control mode, through the different operations of multiple fingers can achieve different control effects, improving the user's control experience.
3. good development and expandability: multi-touch technology can be customised according to the different needs of the user's touchpad or touch software, and with professional graphics software, to facilitate the work.
4. Strong adaptability: multi-touch screen in the ambient light impact, detection time and other aspects of strong adaptability, can work properly in a variety of light conditions, and fast response speed.
5. Wide range of applications: multi-touch screen applications are very wide, covering almost all the areas that require touch screen technology, with great market potential.
