1. Detect touch and locate: all kinds of touch screen technologies work with their own sensors, and even some touch screens themselves are a set of sensors. Each has its own positioning principle and its own sensor. The response rate, reliability, stability, and lifespan of the touch screen, and the sensor method of the touch screen of the touch all-in-one machine also determine how the touch screen recognizes the problem of multi-touch, that is to say, what should be done with additional touches that exceed a little? What should we do when many people touch and many people next to it touch? It is a problem that often arises in the process of touch screen applications. Now this solution has been continuously improved.
2. It has transparency: it immediately affects the visual effect of the LCD touch all-in-one machine. It is transparent. In the touch screen industry, it is just a general concept. Many touch screens are multilayer composite films. Only a little transparency is used to summarize it. The visual effect is not enough. It should include at least 4 characteristics: transparency, color distortion, reflectivity and clarity, and can be further divided. For example, the degree of return light includes the degree of mirror return light and the degree of diffraction return light, but it is just The diffracted light on the surface of our touch screen has not yet reached the level of CD discs. For users, these 4 features are basically sufficient.
3. Affirmative coordinate system: the touch all-in-one machine selects a positive coordinate system, and clicks wherever it should be selected. The difference from a relative positioning system such as a mouse is the intuitiveness of the first time, and the characteristic of the affirmative coordinate system is every time The positioning coordinates have nothing to do with the last positioning coordinates. Physically, it is a separate coordinate positioning system. The data of each touch is converted to the coordinates on the screen according to the calibration. In this way, the touch screen is required no matter what the set of coordinates is. In this case, the output data at the same point is stable. If it is not stable, then the touch screen cannot guarantee a certain coordinate positioning, and the point is not accurate. This means that the touch screen's most feared problem: drift, technical principles can't be guaranteed. Touching the same point every time a touch screen with the same sampled data is unavoidable to drift, but for a touch screen with good performance and quality, the drift is not necessarily serious.
4. Easy to operate: You can enter the information world by simply touching the relevant department buttons on the screen with your fingers. The relevant information can include text, animation, music, video, games, etc.
5. Friendly touch all-in-one machine interface: customers can clearly understand all the information, prompts and instructions on the touch all-in-one machine without mastering the professional skills of the computer. The interface is suitable for customers of all levels and ages.
6. Rich and rich information: The amount of information storage is almost unlimited. All complex data information can be incorporated into the multimedia system, and the types of information are rich and varied, which can be both audiovisual and audiovisual, and the changeable display effect is exciting.
7. Fast response: The system uses cutting-edge technology to query large-capacity data, and the response speed is at a fingertips, no need to wait, and truly achieve the "Pentium" speed.
8. Good scalability: The touch all-in-one machine has excellent scalability, which can add system content and data anytime and anywhere, and provide convenience for future networking and multi-database operations.
