Ambient light factor, infrared receiver tube has a working range between minimum sensitivity and maximum illumination, but touch screen products can not limit the range of use, from the dark cabaret room to the outdoor use under the high-intensity sunlight on Hainan Island, as a product, it must adapt.
For rapid detection, the general size of the infrared touch screen also has at least 64 sets of infrared tubes, which means that an infrared detection is required to be completed within at least 0.4 milliseconds.
Surrounding reflection, refraction, interference, infrared emitting tube has a transmission angle, the receiving tube has a large range of receiving angle, if the surrounding reflection to a certain extent, you will find that your finger can not block the signal wherever you put it.
To solve these problems, the biggest advantage of choosing the simulation method is that it can analyze and improve the resolution of the touch screen, but the anti-interference ability is not as good as the pulse mode; Although the pulse mode has strong anti-interference ability, there is a problem that the pulse mode needs a response process time on the receiver, while the touch screen requires extremely fast speed, so it is necessary to have technological breakthroughs in several aspects such as adaptive circuit, single-chip microcomputer software, mold design, and light transmission material selection.
Infrared touch screen relies on multiple pairs of infrared transmitting and receiving tubes to work, infrared tube performance and life are more reliable, any object blocking light can be used as a touch object, but the number of infrared touch screen sensors is nearly 100 pairs, and the peripheral circuit is shared, which requires the sensor not only to have good performance itself, but also requires nearly 100 pairs of infrared diodes "light-resistance characteristics" and "junction capacitance" are consistent. In practical application, in case of a pair of failures, it can be found during the power-on self-test process and ignored thereafter, relying on the adjacent infrared instead, because each pair of infrared only "supervises" a narrow band of about 6mm, and the finger is usually about 15mm thick, the user is not perceptible. However, if there is no aging test for the infrared emitting tube in the production process and a good quality management system, nearly 100 pairs of sensors will soon not be a problem of "falling behind" in pairs and pairs, and the overall life will be difficult to guarantee. Therefore, users who buy infrared screens should know whether the manufacturer has strict quality inspection methods or whether it has passed ISO9000 certification.
The infrared screen relies on the work of the infrared matrix, the x and y coordinates of multiple points on the matrix can be combined to create a square multiple of the touch point, such as the case, A, B two points and C, D two points are the same effect on the infrared screen, can not be distinguished, its processing method, the infrared screen on the market for multi-touch common processing regardless of whether it is continuous or not, either do not judge, or judge the upper left corner, that is, whether it is A, B or C, D are judged to be C points. The real technology of the hard infrared screen should be the coordinate continuous multi-touch judgment of the middle point, that is, the judgment of large objects (such as thick fingers) of the touch, and the discontinuous multi-touch is not judged, so it is said that the technology is excellent is that this algorithm has stricter requirements for the quality of the product, and does not allow all kinds of failures.
