After major players in the market, such as Samsung and Apple, IBM have patented a flexible electronic display device. Flexible design allows you to use this device as a smart-watch, smartphone or tablet. This way, you can choose the correct screen size for each case.
The patent application is entitled Variable display size for electronic display device (Variable display size for equipment for electronic images) was filed in 2016. It lasted until June 11, 2019, while the patent was approved and published by the US Patent Office. To get the best idea, LetsGoDigital brought several 3D visualizations, but only for illustrative purposes, based on the information described in the patent.
In the most compact form the user has an ordinary clock with a rectangular display on his hand, perhaps a bit thicker. No frames are visible. A feature of the design is that under the main screen there are seven additional parts. These displays can be independently selected from the body. The case has four compartments, each of which has a maximum of two sections of the display.
If you do not have the size of the smart watch display, you can easily pull out the other part of the lid. If you remove four parts of the screen, the device automatically switches to smartphone mode. Thus, the user has a different interface, which should facilitate the use. It can display more icons or larger images. If you need an even bigger screen, such as watching videos or browsing the web, you can pull out the other parts and get an extra wide screen. When you distribute all 8 parts of the display, the smartphone goes into tablet mode, which requires two-way operation. The display is almost seamless, so the content can be displayed continuously.
However, it is not clear from the patent whether the display expansion is manual, semi-automatic or fully automatic. Of course, it would be better if it happened automatically. Dimensions are also given in the patent. Each part of the display has a size of 5 × 7.5 cm (W × V). This is the size of the smart watch display. If you use the device as a smartphone, you have a 10×15 cm display that is considerably wider than the usual smartphone. The fully dispersed screen has a size of 8 × 12 inches (20 × 30 cm) specified in the patent. Perhaps this is an error, it seems from the logic that the fully torn screen has a fourfold width and a double height of one part of the display.
The patent no longer applies to the user's experience. Therefore, the question is how to place a tablet-sized tablet device that has a clock belt on the back. It is possible that the strap is designed to work as a tablet stand. The mobile device should also be equipped with one or more speakers, and also allow the peripheral devices, such as a keyboard and a mouse, to be connected.
In 2000, IBM introduced a prototype of a prototype smart-clock based on the Linux operating system. It was equipped with a memory of 8 MB, an accelerometer and a vibration mechanism. Later Linux Watch was renamed the IBM WatchPad and received touch screen, calendar software and Bluetooth support. In this model, there was also a fingerprint reader. Whether an approved patent means that the company is preparing a smart-watch with a folding display, or it is preferable to sell patent technology to other interested parties.
