The development process of mobile phones is a variety of technological innovations, among which screen changes have brought about technological upgrades to a greater degree. Current mobile phones generally use capacitive screens as screens. The emergence of such screens makes touch screen operations become Possibly, the emergence of the iPhone has led to a new development point in the development of mobile phones, but going back to the branch development point of the mobile phone screen, the resistive screen has to be mentioned.
Compared with the capacitive screen, the resistive screen does not rely on touch operation but press operation. This type of pressing is different from the original keyboard pressing. It is more convenient to operate the mobile phone by pressing directly on the screen. Pressing has great limitations in function, and multi-touch can be realized with the advantage of capacitive screen.
However, the capacitive screen also has many limitations. Although it is more convenient to operate, it is easy to accidentally touch the capacitive screen in some use environments. The realization of the fingerprint under the screen proposes a new possibility. The capacitive screen has functions in the direction of development. On the branch, the specific functions of the specific screen area have further expanded the functions of the mobile phone. The realization of ultrasonic recognition has led to a new screen possibility, that is, the mobile phone can be operated without directly touching the screen, which makes the operability of the mobile phone improved. It has been further improved, but the functional expansion of the mobile phone screen cannot be improved by the convenience of screen operation, and the interactive mode also needs to be improved.
One possible development direction is to upgrade the display of the screen from 2D to 3D, which means that the screen has a projection-like effect, but there should be a better solution in implementation.
It is a bit inconvenient to only change the display mode of the screen. With the development of AI, it will be possible to directly operate the phone with the eyes. Just move the eyes to complete the same operation as the fingers, which will be more convenient in terms of operability. In fact, this kind of technology has already developed to a certain extent. This kind of function has been added to the functions of smart glasses, but this kind of technology is not yet mature. When it can be widely applied to mobile phones, the development of mobile phones will usher in another development. An innovation.
Is a mobile phone screen necessary? The development of technology will make a great change in the screen. From the inoperable screen in the past to the touch screen in the present, the screen in the future will be directly generated. In science fiction film and television dramas, the projected image will look more realistic. This is also technology. The development trend of mobile phones, as a portable product, should not be limited to a certain limited range on the screen display. According to this development point of view, mobile phones will also be upgraded from separate devices to implants. This means that taking out the mobile phone will be cancelled, and using mobile phones anytime and anywhere will become a very common phenomenon.
