According to the patent, this kind of display is developed because the functions of electronic equipment are more and more, which puts forward new requirements for the appearance of electronic equipment. LG said that the retractable screen technology will use the characteristics of flexible screens to fold the redundant parts into electronic devices, thus achieving the effect of screen expansion and contraction.
Similar to the recently popular folding screen, the telescopic screen can also bring many benefits to users. Users can adjust any area of the display unit according to their own needs. In this respect, the retractable screen has more advantages than the foldable screen, because the retractable screen is not limited to two shapes and can provide users with more choices.
LG also said that such a display unit is equipped with a touch sensor and a grip unit, which will learn the user's behavior and expand it without requiring the user to explicitly input instructions. Therefore, if the user chooses to expand the screen when watching the video at ordinary times, the device will learn the user's behavior and then automatically stretch the screen when the user watches the video again.
In addition, the diagonal and vertical expansion of the device design is more conducive to strengthening the grip of the mobile phone, which allows users to adjust the electronic device to the size that best suits their palm. This will be a very practical design, because most modern smart phones are large monitors, which are not suitable for users with petite palms. Compact smartphones are also being eliminated by the market, and devices with adjustable screens can meet the needs of various users, so they will be more competitive in the market.
It is worth mentioning that companies like LG apply for many creative patents every year, but not all of them are commercialized. If LG really intends to push this idea forward, it is unlikely to carry out large-scale sales in the short term. At the same time, such a design will have its own limitations, and LG must overcome any potential challenges it may face before it can continue this idea. In fact, as early as 20 17, Samsung also developed a scalable prototype display, but it is more like an elastic display. Until now, the company has not commercialized it. Undoubtedly, the patent obtained by LG is an exciting moment for the display industry, and this idea may change the way users interact with devices.
