Transparent, it directly affects the touch screen visual effects. Transparent and transparent degree of the problem, the infrared technology touch screen and surface acoustic wave touch screen separated by a layer of pure glass, transparency can be considered outstanding, other touch screen this point should be carefully scrutinize it, "transparent" in the touch screen industry, only a very As a general rule, many touch screens are multi-layered composite films. It is not enough to simply summarize their visual effects with transparency. It should include at least four features: transparency, color distortion, reflectivity and sharpness, Points, such as the degree of reflection, including the degree of reflection of the mirror and the degree of diffraction reflections, but the touch screen surface diffraction refraction has not yet reached the extent of the CD, the user, these four measures have been basically enough.
Due to the existence of light transmittance and wavelength curve, the image seen through the touch screen inevitably has color distortion with the original image, the static image feeling is just the color distortion, and the dynamic multimedia image feeling is not very good Comfortable, color distortion is the maximum color distortion in the picture is naturally smaller is better. The so-called transparency can only be the average transparency of the figure, of course, the higher the better.
Reflective, mainly due to specular reflection caused by overlapping images behind the light and shadow, such as silhouette, windows, lights and so on. Reflective touch screen is the negative effect, the smaller the better, it affects the user's browsing speed, serious or even unrecognizable image characters, reflective touch screen with strong use of the environment is limited, on-site lighting layout also forced to be adjusted. Most touchscreens with reflective issues offer a different type of surface finish: matte touchscreen, also known as anti-glare, slightly more expensive, and significantly less anti-glare retroreflectivity for use in halls or exhibitions where lighting is plentiful Places, however, anti-glare-type translucency and sharpness also will have a more substantial decline. Sharpness, some touch screen installation, the writing is blurred, the image details blurred, the entire screen appears vague, do not see clearly, this is the sharpness is poor. The problem with sharpness is mainly the touch screen of a multi-layer thin film structure, which is caused by the light refraction and refraction between the thin film layers. In addition, the anti-glare touch screen also reduces the sharpness due to the surface frosting. Clarity is not good, the eyes easy to fatigue, there is also some damage to the eyes, pay attention to distinguish when choosing a touch screen.
