玻璃屏的左上角和右下角各固定了竖直和水平方向的超声波发射换能器，右上角则固定了两个相应的超声波接收换能器。玻璃屏的四个周边则刻有45°角由疏到密间隔非常精密的反射条纹。。并且可针对用户定制扩充功能，如网络控制、声感应、人体接近感应、用户软件加密保护、红外数据传输等。原来媒体宣传的红外触摸屏另外一个主要缺点是抗暴性差，其实红外屏完全可以选用任何客户认为满意的防暴玻璃而不会增加太多的成本和影响使用性能，这是其他的触摸屏所无法效仿的。这些正是国外非红外触摸屏的国内代理商销售宣传的红外屏的弱点。而新的技术五代红外屏的分辨率取决于红外对管数目、扫描频率以及差值算法，分辨率已经达到了1000X720，至于说红外屏在光照条件下不稳定，从二代红外触摸屏开始，就已经较好的克服了抗光干扰这个弱点。

Vertical and horizontal ultrasonic transmitting transducers are fixed in the upper left corner and lower right corner of the glass screen, and two corresponding ultrasonic receiving transducers are fixed in the upper right corner. The four peripheries of the glass screen are engraved with reflective stripes with a 45-degree angle from sparse to dense. . And can be customized for users to expand functions, such as network control, acoustic induction, human proximity induction, user software encryption protection, infrared data transmission and so on. Another major disadvantage of the original infrared touch screen promoted by the media is its poor anti-violence. In fact, any anti-riot glass that customers think is satisfactory can be used for the infrared screen without increasing too much cost and affecting the performance, which is unmatched by other touch screens. These are the weaknesses of infrared screens sold and publicized by domestic agents of foreign non-infrared touch screens. The resolution of the new technology, the fifth generation infrared screen, depends on the number of infrared tubes, scanning frequency and difference algorithm, and the resolution has reached 1000X720. As for the instability of the infrared screen under lighting conditions, the weakness of anti-light interference has been well overcome since the second generation infrared touch screen.
