Touch screen technology still needs to be improved

Although the actual application of touch screens is increasing and the application scope is becoming wider and wider, in fact, this technology still has many areas that need to be improved. Only by designing a more advanced, intelligent and considerate human-machine interface, making touch operation more intuitive and accurate, and not affecting the response speed of the system, can it be expected to become the mainstream interface of human-machine interaction. The most typical example is the feedback problem in touch operation. In mobile phone applications, touch screens can largely replace keys. However, from the perspective of consumer usage habits, traditional keys still have a feature that touch screens do not have—tactile feedback. Through keys, many users can make calls and send text messages by touch judgment even without looking at the keyboard, but currently the touch screen is unable to complete this task. Users can only stare at the screen and aim with their fingers to operate. In the future, it is necessary to add appropriate key feedback mechanisms to virtual keys, such as sound or vibration devices, to be closer to consumer usage habits.

In addition, touch screens also have problems such as life and volume. Generally speaking, the service life of a touch screen is definitely much shorter than that of a key keyboard. If a protective film is attached to the screen, the sensitivity and accuracy of touch screen operation will be reduced. If the product also has a need for miniaturization, then a too small screen will make touch operation more difficult, resulting in a negative effect.

In addition, many companies are now working on the development of embedded touch screens, touch screens for electronic paper, OLED (organic light-emitting diodes), etc. It can be seen that there is still a lot of room for technological improvement in the touch screen industry, and there are still many potential market demands to be developed. Therefore, it can also be seen that as a newly emerging input control interface, Chinese companies still have a lot to do in this field.
