However, this type is different from the above-mentioned touch panel. Let’s take a look at the electromagnetic induction touch panel. This method is suitable for LCD drawing boards, tablet computers, photo booths and other equipment.with super mini pc For example, if it continues to develop, it will definitely become the benchmark of the industry and play an important role in leading the market. https://www.geshemruggedpc.com/
This input method was originally used for a drawing board without a display, and a high-precision touch panel was realized by combining a sensor with a liquid crystal panel. When a user touches the screen with a special stylus that can generate a magnetic field, the sensor on the panel receives electromagnetic energy, thus sensing the position of the stylus.
Because you need to use a special stylus, you can’t use your fingers or a universal stylus for input, so the application of this method is limited. However, there are good and bad things. It avoids input errors caused by the surrounding environment or unintentional touching of the screen. Since this technology was originally applied to the tablet, it can provide excellent sensor accuracy, for example, when the stylus is pressed to the screen (electrostatic capacity), the line width can be smoothly changed by accurately sensing the pressure. This design method also makes the screen have high light transmittance and durability.
Summary of development trend of touch panel sensing method
The following table summarizes the features of the touch panels we have seen. It should be noted that even devices based on the same sensing method have different performances and functions. This information is only an introduction to the general product characteristics. In addition, because the touch panel technology is changing with each passing day, the technology is constantly innovating and the cost is constantly decreasing, so the following information is only the current trend as of September 2010.
