Image Recognition TFT Display Module

Image recognition: By Camera (CMOS / CCD) calculated by the lighting changes of the contact surface of the front or back of the observation position.
Many studies have interactive games or multi-touch will come into contact with, is the most famous in the above Jeff Han of the proposed method, the most popular Microsoft Surface is now using similar technology, its technical advantages can determine physical contact with the object, and then make more applications, but its drawback is because from the forward or backward using the Camera to observe and therefore requires a certain amount of space and distance, and the use of infrared light source as an image, vulnerable interference can not be used with flat-panel displays, most of them need to match the projected do use.
Determination is obvious to have a distance, such as a table to the ground, the other is certain with the projector.mini lcd module
Several light source, according to its technical e.g. Jeff Han conduction of the light source in which the acrylic, the light source is provisioning around Surface irradiating infrared light source in the back (inside the table), in before Microsoft also made two camera images superimposed way to determine (TouchLight), as well as foreign graduate students use water bag to produce a light source conduction change quite a lot of the market floor or wall interactive advertising using In a similar way, there are many game consoles design games in this way, Japan and even developed the use of this technology in the remote hand as a TV remote control.lcm module
