This application claims the priority of the Chinese patent application filed on Apr. 17, 2020 before the Chinese Patent Office with the application number of 202010304731.0, the entire contents of which are incorporated herein by reference.
The present application relates to the technical field of electronic apparatuses, and more particularly, to a foldable display device, a mobile terminal and a display method.
Mobile terminals with foldable screens have begun to appear, and major manufacturers have launched their own products. However, from the view of market, foldable flexible screens of current products are all combined with apparatuses, which are relatively thick in overall thickness, giving users a bad experience.
The foldable screen will not display all areas for a long time when in use, so it is necessary to protect the parts that are not frequently displayed.
The present application provides a foldable display device, a mobile terminal and a display method, so as to protect a flexible screen part which is not frequently displayed.
The present application provides a foldable display device, including:
a flexible screen, wherein the flexible screen is configured for displaying an object, and includes a first part and a second part, and a bendable third part between the first part and the second part; and
a housing, wherein the housing includes a front side of the housing, and the first part is slidably supported on the front side of the housing; and the housing further includes a holding tank extending in parallel with the front side of the housing, and when the third part is bent, the second part is capable of sliding into the holding tank.
The foldable display device can partially hold the flexible screen into the holding tank, thus avoiding the part from contacting with the outside world so as to protect the part.
As an optional solution of the foldable display device above, a sensor and a controller are further included, wherein the sensor is on the third part to detect a state of the third part, and the controller controls display of the first part, the second part and the third part according to the state.
Since main deformation of the flexible screen occurs in the third part, setting the sensor in the third part can timely and accurately acquire a bent state of the flexible screen, and acquire the state of the flexible screen through the sensor and control a display area of the flexible screen, thus enriching a display state of the flexible screen.
As an optional solution of the foldable display device above, the sensor is a bending sensor.
As an optional solution of the foldable display device above, the flexible screen is provided with supporting mechanisms, the front side of the housing and the holding tank are provided with guide parts extending in a slide direction, and the supporting mechanisms are slidably connected to the guide parts.
As an optional solution of the foldable display device above, the guide parts are arranged on both sides of the front side of the housing and the holding tank in the slide direction, the supporting mechanisms are arranged on both sides of the flexible screen in the slide direction, and the guide parts are covered on the supporting mechanisms.
The two sides of the flexible screen are provided with the supporting mechanisms and covered by the guide parts, so that a certain dustproof effect can be achieved.
As an optional solution of the foldable display device above, the supporting mechanism is arranged on a non-display surface of the flexible screen, the guide part is one of a rib and a chute, and the supporting mechanism is provided with the other of the rib and the chute.
The present application further provides a mobile terminal, including the foldable display device above.
The present application further provides a display method, using the foldable display device above, including the steps of:
detecting a state of the third part; and
respectively controlling display of the first part, the second part and the third part according to the state.
As an optional solution of the display method above, the state includes a bent state and a flattened state.
As an optional solution of the display method above, the respectively controlling the display of the first part, the second part and the third part according to the state includes:
when the state is the bent state, controlling the first part and/or the third part to display and controlling the second part not to display; and
when the state is the flattened state, controlling the first part, the second part and the third part to display simultaneously.
The mobile terminal provided by the present application can partially hold the screen into the holding tank, thus avoiding the part from contacting with the outside world so as to protect the part. By obtaining the state of the third part of the flexible screen, the display area of the flexible screen is controlled, thus enriching the display state of the flexible screen.

The present application provides a foldable display device.
As shown in
It should be noted that in this embodiment, the third part 23 is arranged on a right side of the foldable display device, that is, the flexible screen 2 can slide from left to right.
The third part 23 may also be arranged at a bottom of the foldable display device in a length direction. In this case, the flexible screen 2 can slide out from the bottom of the foldable display device in the length direction, but the present application is not limited to this.
As shown in
It should be noted that a length of the first part 21 is greater than a length of the second part 22, so that when the first part 21 slides to a tail end, the second part 22 is fully extended protruded out from the holding tank 1C. In this embodiment, the length of the first part 21 corresponds to a length of the front side 1A of the housing, while the length of the second part 22 is ⅘ of the length of the first part 21.
The mobile terminal further includes a sensor 3 and a controller. The sensor 3 is on the third part 23 to obtain a state of the third part 23, and the controller controls display of the first part 21, the second part 22 and the third part 23 according to the state.
In this embodiment, the sensor 3 is a bending sensor.
When the sensor 3 determines that the third part 23 is in a bent state, a display state of the foldable display device may be set as follows: in a first case, contents are displayed on the first part 21 only; in a second case, contents are displayed on the third part 23 only; and in a third case, contents are simultaneously displayed on the first part 23 and the third part 23. In other words, when the third part 23 is in the bent state, contents are not displayed on the second part 22 in the holding tank 1C.
When the sensor 3 determines that the foldable display device is in a flattened state, the display state of the foldable display device may be set as follows: contents are simultaneously displayed on the first part 21, the third part 23 and the second part 22.
It should be noted that although the second part 22 may not be coplanar with the first part 21, due to a factor of display effects, a user is allowed to continuously bend the third part 23, so that the first part 21 and the second part 22 are on the same horizontal plane, that is, an included angle between the first part and the second part is 180 degrees.
In this embodiment, the bent state means that the third part 23 makes the included angle between the first part 21 and the second part 22 range from 0 degree to 170 degrees, and the flattened state means that the third part 23 makes the included angle between the first part 21 and the second part 22 range from 0 degree to 180 degrees.
As shown in
It should be noted that the flexible screen 2 further includes a retaining mechanism (not shown in the figure) that can keep at any angle when the retaining mechanism bends. In this embodiment, the retaining mechanism is arranged in the third part 23 of the flexible screen 2, and a damping hinge is employed as the retaining mechanism.
