The touchscreen types, performance and features vary with the technology, leading to the confusion of the purchasers. The features of the infrared touchscreen and the acoustic wave touchscreen are compared as follows.
Recently, we have innovated the infrared touch technology for the sixth time, and the resolution ratio rises to 1920×1080. The superior resistance to the strong sunlight interference allows for operation in the direct sunlight. Crucially, a breakthrough is made in the product service life and the maintenance-free advantage. In addition, guided by principle of the probability function distribution and redundancy, we extend the service life to more than 7 years with unlimited touch. That is to say, the touchscreen can remain normal operation at the end of the display service life.
The light resistance of the infrared touchscreen is improving with the continuous updating, For instance, the R, L and the S series are capable of perfect operation in the direct sunlight of more than 100000LUX without any drifting, flickering, being disconnected or crashing. The digital tempered glass with a high light transmittance is applied so the product features the high sharpness, resistance to scratch, damage and stain, long service life and maintenance-free and it requires no pressure to be exerted. Hence, the manufacturing cost is reduced significantly, and the infrared touch screen becomes the first choice of the industries with strict requirement for such products.
Acoustic Wave Touchscreen
Despite the large number of the acoustic wave touchscreen, the difference between them lies in the manufacturing technology and the material, instead of the reaction principle. The product consists of two conducting layers with spacer dots in between. Contacted by human body, the conducting layer will influence the redistribution of current and the screen responses. The special features of the acoustic wave touchscreen allow for the precise positioning, but the product requires regular maintenance since it is vulnerable to stains and dust and other damage in the operating environment. The resolution reaches 4096×4096 and the times of single point touch rise to 30,000,000 so it is applicable for certain software environment. Additionally, the screen is sensitive to the touch with certain pressure degree of less than 3 ounces and the response time ranges from 8ms to 15ms.
The industry insiders are very fond of the advantages of the infrared touchscreen, but are also well aware of its disadvantages. They had made unremitting effort to remedy the defects. Now product with IP65-level water resistance is customized to allow for operation in harsh environment such as rain, snow, mist etc.
In conclusion, both the infrared touchscreen and the acoustic wave touchscreen have superior resistance to water and sunlight and are applicable for the indoor and outdoor all in one computer, vehicular equipment and transportation and more.
