The first characteristic of touch screen:
Transparent, it directly affects the visual effect of touch screen.
The problem of transparency is the degree of transparency, infrared technology, touch screen and surface acoustic wave touch screen is separated by a layer of pure glass,
Transparency can be considered a leader, the other touch screen this is a good scrutiny, transparency",
The touch screen industry, is a very broad concept, many touch screen is a multilayer composite film,
It''s not enough to generalize its visual effect with only a little transparency,
It should include at least four characteristics: transparency, color distortion, reflection and clarity, but also,
For example, the degree of reflection, including the degree of specular reflection and diffraction,
But the touch screen surface diffraction reflection has not reached the extent of the CD disk,
For users, these four metrics are basically enough GT16-90PSGB datasheet PDF catalog GT16-90PSGB PDF datasheet GT16-90PSGB datasheet PDF catalog GT16-90PSGB PDF datasheet. "Oil resistant cap for 8.4 inch screen.

From the technical principle to distinguish the touch screen, can be divided into five basic types: vector pressure sensor touch screen, resistive touch screen, capacitive touch screen technology, infrared touch screen technology, surface acoustic wave touch screen technology.
Vector pressure sensing technology touch screen has been withdrawn from the stage of history;
Infrared touch screen technology and low price, but the frame is fragile, easy to produce light interference and surface distortion;
The design of capacitive touch screen is reasonable, but it is difficult to solve the problem of image distortion;
The touch screen positioning resistor technology is accurate, but its price is high, and fear of vulnerability scratch;
The surface acoustic wave touch screen solves various defects of the touch screen in the past,
Clear and not easy to be damaged, suitable for vaarious occasions,
The disadvantage is that the screen surface if there is water droplets and dust will make the touch screen become slow, or even work GT16-90PSGB datasheet PDF catalog GT16-90PSGB PDF datasheet GT16-90PSGB datasheet PDF catalog GT16-90PSGB PDF datasheet.
