Detailed Description
The embodiment of the invention provides a display device and a control method thereof, aiming at the problem that the folding degree of a foldable display device cannot be detected in the prior art.
The following describes in detail a specific embodiment of a display device and a control method thereof according to an embodiment of the present invention with reference to the drawings. The thicknesses and shapes of the various film layers in the drawings are not to be considered true proportions, but are merely intended to illustrate the present invention.
In a first aspect, an embodiment of the present invention provides a display device, as shown in fig. 1 and fig. 2, including: a display panel (not shown), a sensing structure T, and a detection circuit (not shown); wherein the content of the first and second substances,
the display device comprises at least one bending area B, wherein a first display area A1 and a second display area A2 are arranged on two sides of the bending area B; the sensing structure T and the bending region B have an overlapping region, and one end C1 of the sensing structure T is located in the first display region a1, and the other end C2 is located in the second display region a 2;
the sensing structure T is used for detecting the deformation of the display panel and outputting a detection signal;
the detection circuit is electrically connected with the sensing structure T and used for detecting a detection signal output by the sensing structure T, determining the folding degree of the display panel according to the detection signal and outputting an instruction for controlling the display device to execute corresponding operation according to the determined folding degree.
According to the display device provided by the embodiment of the invention, the deformation of the display panel can be detected by arranging the induction structure, the detection circuit can determine the folding degree of the display panel according to the detection signal output by the induction structure, and further output the instruction for controlling the display device to execute the corresponding operation according to the determined folding degree, so that the detection of the folding degree of the display panel is realized, and various interaction modes of the foldable display device can be realized.
The display device provided by the embodiment of the invention can be applied to any products or components with display functions, such as mobile phones, tablet computers, televisions, displays, notebook computers, digital photo frames, navigators and the like. In the display device provided by the embodiment of the invention, the display panel can be an organic electroluminescent display panel, and the organic electroluminescent display panel has better flexibility, so that the foldable function is easier to realize.
In practical applications, the display device at least includes one bending region B, and the display device can be folded at the bending region B, which is only illustrated in fig. 1 and 2 as the display device including one bending region B, and the display device may also include a plurality of bending regions B, where the number of bending regions B is not limited.
It should be noted that the first display region a1 and the second display region a2 on both sides of the bending region B are display regions in a broad sense, that is, the first display region a1 (or the second display region a2) may include a small portion of a frame region having no display function in addition to the display region.
As shown in fig. 1 and 2, the display device can be folded along the extending direction of the bending region B (i.e. the dotted line L in the figure), that is, the bending region B is generally a strip-shaped region penetrating the display device in the direction of the dotted line L. Set up induction structure T to have the overlap region with bending region B, and, induction structure T's one end C1 is located first display area A1, and other end C2 is located second display area A2, and induction structure T is through bending region B yet, thereby can make display device fold along bending region B time, induction structure T can buckle along with display device's the buckling, thereby can guarantee that induction structure T can detect display panel's deformation.
The detection circuit is electrically connected to the sensing structure T, and the detection circuit may determine the folding degree of the display panel according to a detection signal output by the sensing structure T, for example, a plurality of threshold ranges may be preset, and determine the folding degree by determining which threshold range the value of the detection signal is located in, and then output an instruction for controlling the display device to perform a corresponding operation according to the determined folding degree, for example, may control the display device to perform operations such as waking up, zooming, or switching a picture according to different folding degrees. In addition, the display device may be controlled to perform corresponding operations according to the trend of the change of the folding degree, for example, an operation of enlarging the screen may be performed when the folding degree is detected to be gradually increased, an operation of reducing the screen may be performed when the folding degree is detected to be gradually reduced, or an operation of switching the screen may be performed when the folding degree is detected to be increased and then reduced.
In addition, the stress state of the display panel can be reflected through the determined folding degree of the display panel, and when the bending degree is detected to be higher, the detection circuit can also send corresponding warning information to remind a user that the stress received by the display panel is larger at the moment, so that the display panel is prevented from being damaged due to overlarge stress.
Specifically, the sensing structure T may be a conductive structure, for example, the sensing structure T may be made of a metal material. Since the resistance value of the sensing structure T is related to the material, the length, the cross-sectional area, and other factors, when the display device is folded along the bending region B, the sensing structure T is also deformed at the corresponding position, and thus, the length and the cross-sectional area of the sensing structure T are also changed, which further causes the change of the resistance of the sensing structure T, and thus, the bending degree of the display panel is determined by detecting the resistance of the sensing structure T or detecting parameters related to the resistance of the sensing structure T, such as voltage or current.
Specifically, the strain epsilon and the resistance change rate dR/R of the sensing structure T are generally in a linear relationship, and the specific relationship is as follows: and dR/R is Ks epsilon, wherein Ks is the sensitive coefficient of the material, the physical meaning of Ks is the resistance change rate of unit strain, whether the resistance of the material is obviously influenced by stress can be reflected, epsilon represents strain and is a dimensionless quantity, but the unit is used as micro strain, and the strain epsilon of the sensing structure T and the resistance change rate dR/R are in a linear relation obviously according to the relational expression. In specific implementation, in order to more accurately detect the bending degree of the display panel, a material with a larger sensitivity coefficient Ks may be selected to fabricate the sensing structure T.
Specifically, as shown in fig. 3, the display device provided in the embodiment of the present invention may further include: a protective layer 102 on the display surface side of the display panel 101, and a supporting mechanism 103 on the side of the display panel 101 facing away from the protective layer 102.

In practical applications, in the display device provided in the embodiment of the present invention, referring to fig. 3, the sensing structure may be located on an outer surface of the display panel 101, that is, the sensing structure may be located on a side of the substrate of the display panel 101, which is away from the display surface, or the sensing structure is located on a surface of an outermost film layer of the display panel 101 on the side of the display surface. In an actual process, the sensing structure may be directly formed on the outer surface of the display panel 101, or the manufactured sensing structure may be directly attached to the outer surface of the display panel 101.
Alternatively, the sensing structure may be located between any two adjacent film layers on the display panel 101. The induction structure is arranged inside the display panel 101, so that the connection between the induction structure and the display panel 101 is firmer, and the deformation detected by the induction structure is more accurate.

In addition, the sensing structure may also be disposed on the surface of the supporting mechanism or the protective layer, the sensing structure may be formed on the surface of the supporting mechanism or the protective layer by using a related process, or the manufactured sensing structure may be directly attached to the surface of the supporting mechanism or the protective layer, where the position of the sensing structure is not limited.
In the display device according to the embodiment of the present invention, as shown in fig. 1, the sensing structure T may be a curved structure. The figure only shows that a comb-shaped structure is formed by a single curved line-shaped structure, and in the specific implementation, the sensing structure T may be formed by another curved line-shaped structure, which is not limited herein.

In the figure, the outline of the grid-shaped structure is only illustrated as a rectangle, and in the specific implementation, the outline of the sensing structure T may be in other shapes, which is not limited herein.
