LCD Touch screen For iPhone 8P

                                                  Prospects for the Application of Touch Screen Technology

The touch screen is not a new concept, since the arrival of the iphone as a multimedia device, touch screen technology has become extremely popular and benefited from a lot of innovation. Previous touch screens were used to replace keyboards and mice, and today they convey a whole new operating experience. With more interaction between the user and the device, this new "touch" experience has been achieved with a different combination of technologies.

Prospects for Interactive Multimedia Applications:
Touch screen technology is becoming more and more popular. We can see the existence of touch interface in consumer electronics products, advertising machines, household appliances, even test instruments, medical equipment, etc. Touch screen technology is our topic today.

Interactive multimedia touch technology opens up a new era of interactive advertising. Advertising may have grown up with many people when they were born in this world. No matter what kind of space we are in, advertising information can always penetrate into every corner. It is often seen in shopping malls, cinemas, airports, restaurants and other public spaces. From digital signage to digital signage advertising machines, they only publish information mechanically and cannot provide consumers with an interactive experience to meet personalized information needs. With the continuous innovation and application of interactive multimedia technology, interactive multimedia technology is gradually combined with advertising, and the interactive advertising model is just around the corner. Consumer needs are met in two directions in the interactive space.

Interactive touch technology may become a digital signage display screen. The digital signage user interface design with interactive touch technology must take into account the five senses of the user's vision, hearing, taste, smell and touch on the one hand, and on the other hand. The impact of requirements on a device or system.

From the perspective of market research and improving customer experience, the interactive touch system has high efficiency and lower cost, and the real-time information statistics results of interactive digital signage are more targeted, efficient and time-effective. For today's fast-paced market competition, the value of first-hand feedback information is inestimable, so the application of interactive technology in digital signage products will be more marketable and more in line with market demand.

The functions of the touch screen have evolved from simple to complex. The initial product only supports the simplest operation, which is to touch a point on the screen with a finger to realize the operation. In the past, we could only control it through the mechanical buttons around the screen. On this basis, the single touch screen has achieved a great improvement in the user interface. This type of screen brings two major benefits to the user interface. One is that the device design space is optimized, especially for small devices, because it can "install" the screen and buttons in the same area at the same time; two, because the buttons can be bound to the action. Any application in the system, so the device can use an infinite number of "buttons".

Although single-point touch screen and resistive touch screen technology have greatly enhanced human-computer interaction, they still have two major disadvantages. One is that resistive technology relies on the physical movement of the touch screen. , the performance will drop; the second is that this technology only supports single-point touch, that is, only one finger can be used to perform a single action on a certain area of the screen at a time.

And multi-touch can realize the operation of more than two fingers, which further improves the reliability and usability of the touch screen, and can meet the application requirements of various features. Reliability refers to our ability to accurately capture the raw data of all touch points on the screen with the highest granularity, minimizing the confusion caused by inaccurate positioning of touch points on the screen. Usability refers to the ability of many powerful applications to benefit from screen manipulation with two hands or more than two fingers on screens of different sizes. 3D interactive games, keyboard input, and map operations are some of the main objects that use this touch screen functionality.
