1. The optical performance is the best. The clarity and light transmittance are the highest, the reflection is the least, and there is no color distortion, this is because the sound wave screen body is pure glass, unlike the resistive screen with multiple layers of composite film; The capacitive screen is coated with a layer of film on the surface, and the light transmittance is worse.
2. Anti-scratch and anti-barbaric use. Even if the surface of the sound wave screen is scratched, as long as it is not very deep, it will work normally, and the resistance screen will not be able to do this, and it will be broken with a blade.
3. Sound waves are mechanical vibrations, which are not affected by electromagnetic signals, unlike capacitive screens, and are easily affected by electric or magnetic fields and drift.
4. High resolution, reachable, fast response.
5. Long service life, single touch up to 50 million times. This is obvious, the main body of the sound wave screen is pure glass, not like the capacitive screen or the resistive screen to do coating or multi-layer film processing on the glass, these processing is subject to a variety of factors such as light transmission and touch, and the glass screen after processing is obviously not as durable as the pure glass screen. Both resistive screen and capacitive screen are prone to the same software after a long time to touch some points dull or can not touch the situation, this is because the same software to live in some points of frequent operation first aging, but the sound wave screen will not.
6. The disadvantage is mainly affected by dust, water droplets, oil stains, etc., and the reflective array needs to be cleaned regularly.
7. Another major advantage of the sound wave screen is the low cost, for two reasons: first, the technology has been fully mastered in China, and the cost of domestic production is naturally low; Second, the design is exquisite, and only a pair of transducers are used in each direction, which greatly reduces the cost. Especially for touch screens over 10 inches, sonic screens have significant cost advantages, and the larger the size, the greater the advantage.
