Force sensing

Another development which is less used in the user interface of instruments but has great potential, the force sensing. A common defect of LCD touch screen is that when the user looks elsewhere, it cannot provide feedback like a mechanical button. By using force recognition, when touching the lcd touch screen pc lightly, an oral message can alert the user to notice the selected option. The selection can be confirmed by pressing harder. Therefore, for example, when a user's finger moves on the screen, the instrument will make a sound of "temperature", "pressure" or "time". When the finger reaches the correct position, it can press hard to select. In addition, it can provide convenience for amblyopia users through this way.

Extending the force sensing technology of hand-held devices to larger LCD touch screens in commercial and industrial applications is far more than simply extending the same technology. Capacitive sensors of most smart phones are integrated into the display screen. If it is expanded to use large screen, this method will be costly, and this method is not compatible with the protective glass usually installed in the integrated machine and other LCD touch screens used in public places. Through this method, it is not necessary to use piezoelectric layer or other layers on the glass to measure the applied force or pressure, and it means that the technology can even be used on the thick, rigid and anti-damage reinforced glass surface.

Improve electro-magnetic interference (EMI) resistance

Electro-magnetic interference (EMI) is a common problem of LCD touch screen display system used in industrial environment. Similarly, the LCD touch screen deployed in areas with inconsistent power supply or poor voltage stabilization will also be affected by the transient interference generated by the power cable. This will cause the LCD touch screen and its control electronic components to fail in identifying signals (or touch operations) from the surrounding noise, that is, reducing the noise ratio of signal, which is not conducive to identifying real touch activity.

As a National High-Tech enterprise, Amongo is specialized in R&D, manufacturing and marketing of industrial open frame monitors, industrial touch screen monitors, industrial panel PCs, LCD advertising displays, interactive whiteboards with full range selection from 6.5 inch to 70 inch.

Till now, Amongo has developed nearly thousands of different models which are widely applied in Banking ,IoT field, Industrial Automation, Gaming, Retail, Public Information Station, Transportation & Logistics, Healthcare and so on.
