Infrared touch screen 's working priciple
Infrared touch screen 's working principle is :
Touch screen around are full filled with infrared acceptant pipes and emission pipes.
These infrared pipes are in the order of a one-to-one relationship between the surface of touch screen and form an
Optical Network by infrared pipes.When objects enter(which can be fingers, hands with gloves or touch any object) into the infrared optical network and stop infrared emission pipes to receive infrared light, thought analysing the change sutations of infrared lights 's by equipment, then we can be able to know where
we were touching.
Through the infrared touch screen hardware design and software programming
.
Points can be calculated data interpolation to achieve a resolution of 4096 × 4096,
as infrared touch screen itself 's working principle, it can be done without pressure in touching operation and also can be done without glass, (referring to touch on the touch screen's pressure),at the same moment of
the infrared touch screen working, only one pair of infrared pipes (Refers to a corresponding launching tube and receiving tube on physical locations) are on data work, through infrared tubes 'high-frequency Data Acquisition,the circuit achieve rapid response.
Infrared touch screen features
The main disadvantage of touch screens is that they are mainly depending on infrared light to work and are very sensitive to the
illumination Environment.
The touch screen will be making a larger misjudgment or even Dead
when
the Illumination Environment
has a large changed.
when
the Second-generation infrared touch screen
with Anti- light interference fuction appear in our market .
