Detailed Description

Example one

Referring to fig. 1 and 2, an embodiment of the present invention provides a flexible display device, which includes a display portion for displaying a screen, the state of the display portion being divided into an unfolded state and a folded state, as shown in fig. 2, in the folded state, the display portion forms a first display area 11 and a second display area 12, each of which can display an application; as shown in fig. 1, in the expanded state, the first display area 11 and the second display area 12 form a display area, which can display an application. The flexible display device further comprises a detection part for detecting the state of the display part, wherein the detection part comprises a first detection device 21, a second detection device 22 and a state detection unit, the first detection device 21 is correspondingly arranged in the first display area 11, the second detection device 22 is correspondingly arranged in the second display area 12, the relative position of the first display area 11 and the second display area 12 can be changed along with the change of the state of the display part, the relative position between the corresponding first detection device 21 and the corresponding second detection device 22 can also be changed, and the state detection unit can determine that the display part is in a folded state or determine that the display part is in an unfolded state according to the fact that whether the first detection device 21 and the second detection device 22 are close to each other.

In the flexible display device in this embodiment, the detection portion can detect the folded state or the unfolded state of the display portion, and the detection process includes: when the first display area 11 and the second display area 12 approach or contact each other, the corresponding first detection device 21 and the second detection device 22 approach each other, the state detection unit detects some characteristics of the approach between the first detection device 21 and the second detection device 22, and the display portion is determined to be in a folded state because the first display area 11 and the second display area 12 approach or contact each other; when the first display area 11 and the second display area 12 are far away from each other, the corresponding first detection device 21 and the second detection device 22 are far away from each other, the state detection unit detects some characteristics of the distance between the first detection device 21 and the second detection device 22, and the display portion is determined to be in the unfolded state because the first display area 11 and the second display area 12 are far away from each other.

As can be seen from the above process, the flexible display device of the present embodiment can detect the folded state and the unfolded state of the display portion, so that the related operations can be realized in the corresponding states of the display portion.

It should be noted that "close" or "far" between the first detection device 21 and the second detection device 22 in the embodiment of the present invention is explained differently according to different situations, but all are based on a principle: the approach between the first detection device 21 and the second detection device 22 means that an influence can be generated between the first detection device 21 and the second detection device, and the influence can be reflected on the corresponding features; the distance between the first detection device 21 and the second detection device 22 means that the first detection device 21 and the second detection device do not affect each other, and the non-influence can also be reflected on the corresponding characteristics.

Preferably, the detection portion of the flexible display device in this embodiment can have various structures, and thus, the corresponding flexible display device can also have various structures.

Referring to fig. 3 to 5, a first structure of the detecting part is, for example: according to the hall effect, when the distance between the magnet 221 and the hall switch chip 211 is smaller than or equal to the first distance, the magnetic field generated by the magnet 221 will cause the hall switch chip 211 to generate a potential difference, and the potential difference of the hall switch chip 211 is not zero. According to this principle, the embodiment refers to the case that the distance between the magnet 221 and the hall switch chip 211 is less than or equal to the first distance as the magnet 221 is close to the hall switch chip 211, and correspondingly, the state detection unit may include a first judgment subunit 2311 connected to the hall switch chip 211, and a first state determination subunit 2321 connected to the first judgment subunit 2311, where the first judgment subunit 2311 may be capable of judging whether the potential difference of the hall switch chip 211 is zero, and the first state determination subunit 2321 may determine that the display portion is in a folded state when the potential difference of the hall switch chip 211 is not zero; when the potential difference of the hall switch chip 211 is zero, the display section is determined to be in the expanded state.

Referring to fig. 3 and 4, in the flexible display device corresponding to the first structure of the detection part, the process of detecting the state of the display part is as follows: if the potential difference of the hall switch chip 211 is not zero, the magnet 221 and the hall switch chip 211 are close to each other, and correspondingly, the first display area 11 and the second display area 12 are close to each other or are in contact with each other, which indicates that the display part is in a folded state; when the potential difference of the hall switch chip 211 is zero, the magnet 221 is away from the hall switch chip 211, and correspondingly, the first display area 11 and the second display area 12 are away from each other, which indicates that the display unit is in the expanded state.

It can be seen that, in this embodiment, whether the hall switch chip 211 and the magnet 221 are close to each other is characterized by whether the potential difference of the hall switch chip 211 is zero.

Referring to fig. 6 to 8, a second structure of the detecting part is, for example: the first detection device 21 is a first metal plate 212, the second detection device 22 is a second metal plate 222, and sends an excitation signal to one of the metal plates, and if the distance between the two metal plates is smaller than or equal to the second distance, the other metal plate receives the excitation signal. Based on this principle, the present embodiment refers to the case where the distance between the first metal plate 212 and the second metal plate 222 is less than or equal to the second distance as the first metal plate 212 is close to the second metal plate 222, and correspondingly, the state detection unit may include an excitation signal transmitting subunit 233 connected to the first metal plate 212, a second determining subunit 2312 connected to the second metal plate 222, and a second state determining subunit 2322 connected to the second determining subunit 2312, where the excitation signal transmitting subunit 233 may transmit an excitation signal to the first metal plate 212 at a certain frequency, the second determining subunit 2312 may determine whether the second metal plate 222 receives the excitation signal in the first metal plate 212, and the second state determining subunit 2322 may determine that the display portion is in a folded state when the second metal plate 222 receives the excitation signal; when the second metal plate 222 does not receive the excitation signal, it is determined that the display portion is in the unfolded state.

Referring to fig. 6 and 7, in the flexible display device corresponding to the second structure of the detection part, the process of detecting the state of the display part is as follows: when the second metal plate 222 receives the excitation signal in the first metal plate 212, the first metal plate 212 and the second metal plate 222 are close to each other, and correspondingly, the first display area 11 and the second display area 12 are close to each other or contact each other, which indicates that the display part is in a folded state; when the second metal plate 222 does not receive the excitation signal from the first metal plate 212, the first metal plate 212 and the second metal plate 222 are far away, and correspondingly, the first display area 11 and the second display area 12 are far away from each other, which indicates that the display portion is in the unfolded state.

It can be seen that in this embodiment, the proximity between the first metal plate 212 and the second metal plate 222 is characterized by the presence of the excitation signal on the second metal plate 222.

In particular, in order to avoid the influence of the mutual interference between the first metal plate 212 and the second metal plate 222 when the first metal plate 212 and the second metal plate 222 are in contact with each other, the surfaces of the first metal plate 212 and the second metal plate 222 may be provided with an insulating layer.

Referring to fig. 1, 3 and 6, the path along which the display portion is folded is referred to as a fold line 30. Preferably, the folding line 30 may be a center line of the display part, and more preferably, the first detecting means 21 and the second detecting means 22 may be symmetrically disposed with respect to the folding line 30. In this way, when the display portion is in the folded state, the first detection device 21 and the second detection device 22 correspond to each other, and the effect of the mutual influence between the first detection device 21 and the second detection device 22 is more remarkable, so that the folded state of the display portion can be quickly detected.

Further, the detection device may be located at an edge of the display portion so as not to affect a display effect of the display area. Based on the above-mentioned scheme that the folding line 30 is the center line, correspondingly, the first detection device 21 may be located at the edge of the first display area 11 away from the folding line 30; alternatively, the second detection device 22 may be located at an edge of the second display area 12 remote from the folding line 30.

The first detecting device 21 and the second detecting device 22 in the detecting portion may be disposed on a surface of the display portion opposite to the display surface so as not to affect the display effect of the display surface.

The flexible display device can be a mobile phone, a flat panel or a display screen.

Preferably, in this embodiment, for the convenience of detection, the expanded state of the display portion may be set as the initial state of the display portion.

Example two

The embodiment provides a state detection method of a flexible display device, which is applicable to the flexible display device of the first embodiment, and the state detection method includes:

determining that the display part of the flexible display device is in a folded state according to whether a first detection device 21 of the detection part of the flexible display device and a second detection device 22 of the detection part of the flexible display device are close to each other; alternatively, the display portion of the flexible display device is determined to be in the expanded state.

The method for detecting the state of the flexible display device in this embodiment is suitable for the flexible display device in the first embodiment, wherein, whether the first detection device 21 and the second detection device 22 are close to each other is related to the relative positions of the first display area 11 and the second display area 12, when the first display area 11 and the second display area 12 are close to or touch, the corresponding first detecting device 21 and the second detecting device 22 are close to each other, and when the first display region 11 and the second display region 12 are far from each other, the corresponding first detection device 21 and the second detection device 22 are distanced from each other, so that, in the present method, the relative positional relationship between the first display region 11 and the second display region 12 can be determined according to whether the first detection device 21 and the second detection device 22 are close to each other, thereby determining the state of the display portion, and thus performing different operations in the corresponding states. Therefore, the state detection method of the flexible display device in the embodiment realizes the detection of the state of the flexible display device.

Preferably, in combination with the first structure of the detection portion in the first embodiment, the first detection device 21 is a hall switch chip 211, and the second detection device 22 is a magnet 221, and the corresponding state detection method may include:

judging whether the potential difference of the Hall switch chip 211 is zero, if so, determining that the display part is in an unfolded state; if not, the display part is determined to be in a folded state.

Preferably, in combination with the second structure of the detecting unit in the first embodiment, the first detecting device 21 is the first metal plate 212, and the second detecting device 22 is the second metal plate 222, and the corresponding state detecting method includes:

transmitting an excitation signal to the first metal plate 212;

judging whether the second metal plate 222 receives the excitation signal in the first metal plate 212, if so, determining that the display part is in a folded state; if not, the display part is determined to be in the unfolding state.

Further, the surfaces of the first metal plate 212 and the second metal plate 222 are plated with an insulating layer.

It should be noted that, since the state detection method of the flexible display device in the present embodiment is applicable to the flexible display device in the first embodiment, the beneficial effects of the flexible display device in the first embodiment can be used to explain the state detection method in the second embodiment.
