Touchscreen Changed Business

A touchscreen is an electronic visual display that the user can control through simple or multi-touch gestures by touching the screen with one or more fingers. Some touchscreens can also detect objects such as a stylus or ordinary or specially coated gloves. The user can use the touchscreen to react to what is displayed and to control how it is displayed (for example by zooming the text size).

The touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or any other intermediate device.

The popularity of smartphones, tablets, and many types of information appliances is driving the demand and acceptance of common touchscreens for portable and functional electronics. Touchscreens are found in the medical field and in heavy industry, as well as for automated teller machines (ATMs), and kiosks such as museum displays or room automation, where keyboard and mouse systems do not allow a suitably intuitive, rapid, or accurate interaction by the user with the display's content.

The first touch screen features:

Transparent, it directly affects the touch screen visual effects. Transparent and transparent matter of degree, infrared touchscreen technology and surface acoustic wave touch screen are separated by only a layer of pure glass, transparent, can be considered a leader, other touch screen this point we must take deliberate about it, "transparent" , the touch screen industry, only a very general concept , many touch screen is a multi-layer composite film , it is only the transparent one o'clock to summarize the visual effect is not enough, it should be at least four characteristics : transparency , color distortion, reflective and clarity , but also to re- points, such as reflective mirror reflective level including the extent and degree of diffraction reflection , but the touch screen surface diffraction reflex has not reached the level of CD disks , the user, these four metrics have basically had enough.

As translucent presence wavelength graph, the image seen through the touch screen with the inevitable distortion of the original color image generating a static image is a color distortion in feeling, feeling dynamic multimedia picture is not very comfortable, color distortion is the greatest figure in the natural color distortion is smaller the better. Usually referred transparency can only be an average figure of transparency, of course, the higher the better .

Reflective , mainly refers to the resulting image is superimposed on the specular reflection of light and shadow behind , such as shadows , windows, lighting and so on. Reflex is the adverse effect of the touch screen , the smaller the better , it affects the user's browsing speed, even when serious unrecognizable image character , reflective of strong touchscreen restricted
