sharp interactive touch screen table.lFast detection. Generally, the infrared touch screen has at least 64 sets of infrared pairs, which means that it is required to complete an infrared detection at least 0.4 milliseconds. The surrounding reflection, refraction, and interference. The infrared transmitting tube has an emission angle, and the receiving tube has a wide range of receiving angles. If the surrounding reflection reaches a certain level, you will find that your finger cannot block the signal anywhere. To solve these problems, the biggest advantage of choosing the analog 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 method. Although the pulse method is selected, although the anti-interference ability is strong, the pulse method requires a response process at the receiver. The problem of time, but the touch screen requires extremely fast speed, so it is necessary to have technological breakthroughs in several aspects such as adaptive circuits, microcontroller software, mold design, selection of light-transmitting materials.
