Detailed Description
To further explain the technical means and effects of the present invention adopted to achieve the predetermined objects, the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.
First embodiment
Fig. 1 is a system block diagram of a mobile terminal according to a first embodiment of the present invention. The mobile terminal of the present invention may be a mobile phone, a tablet computer, etc., and the present invention is described below by taking the mobile terminal as a mobile phone. As shown in fig. 1, the mobile terminal of the present invention includes a main body, a control unit, and a sensing unit.
Fig. 2 is a schematic structural diagram of the mobile terminal shown in fig. 1. As shown in fig. 2, the main body is generally a rectangular parallelepiped case formed of a material such as plastic, metal, or the like, and constitutes a basic housing of the mobile terminal. The front of the main body is provided with a display screen 10, and the display screen 10 comprises a hard display screen 11 connected with the main body and a flexible display screen 12 connected with the hard display screen 11. In the present invention, the hard display 11 is a so-called hard screen. The hard display 11 and the flexible display 12 are seamlessly docked, that is, when the mobile terminal is in a black state, the hard display 11 and the flexible display 12 have no apparent boundary in appearance. The hard display screen 11 is positioned right above the main body, and the projection of the hard display screen along the thickness direction of the mobile terminal is completely overlapped with the main body. The flexible display 12 protrudes out of the body in the width or length direction of the mobile terminal. Fig. 1 shows that the flexible display 12 protrudes out of the main body of the mobile terminal in the width direction of the mobile terminal.
The flexible display 12 includes a first flexible display 121 connected to the rigid display 11 and a second flexible display 122 connected to the first flexible display 121. A first folding line 123 is formed between the first flexible display 121 and the second flexible display 122, and the first folding line 123 divides the flexible display 12 into the second flexible display 122 and the second flexible display 122. The first flexible display screen 121 and the second flexible display screen 122 have the same length, and since the display screen 10 is placed along the width direction of the mobile terminal, the length of the display screen 10 is the length of the display screen 10 along the width direction of the mobile terminal. The first fold line 123 is located at a fixed distance from the free end of the second flexible display 122. In the present embodiment, the width of the display screen 10 is preferably 74mm, the length thereof is preferably 210mm, the total length of the flexible display screen 12 is preferably 160mm, and the distance between the first folding line 123 and the free end of the second flexible display screen 122 is preferably 80mm. That is, the lengths of the first flexible display 121 and the second flexible display 122 are both 80mm. The flexible display 12 may be folded along the first fold line 123, thereby changing the angle between the first flexible display 121 and the second flexible display 122. In this embodiment, when the flexible display 12 is folded along the first folding line 123, the flexible display 12 does not cover the rigid display 11.
The flexible display 12 may be configured with a housing with the flexible display 12 disposed on a front side of the housing. In view of the characteristics of flexible display 12, the housing of flexible display 12 may be configured to be deformable together with flexible display 12 under an external force. In the present invention, the housing of the flexible display 12 may be made of materials such as plastic, thin glass, fiber, thin metal (e.g., aluminum, etc.), textile, and silicon, or a combination thereof.
The flexible display 12 typically has two extreme position states: a fully unfolded state and a fully folded state. When the flexible display 12 is in the fully unfolded state, the entire image display surface of the flexible display 12 forms a substantially flat surface, and in this state, it can be considered that an included angle of 180 ° is formed between the first flexible display 121 and the second flexible display 122. When flexible display 12 is in a fully folded state, second flexible display 122 is positioned over first flexible display 121 with its image display surface substantially conforming to the image display surface of second flexible display 122, in which state it can be considered that first flexible display 121 and second flexible display 122 form an angle of 0 °. When the angle between the first flexible display screen 121 and the second flexible display screen 122 is greater than a preset angle value (e.g., 90 °) and less than or equal to 180 °, the flexible display screen 12 is considered to be in the unfolded state. When the angle between the first flexible display screen 121 and the second flexible display screen 122 is smaller than the preset angle value and greater than or equal to 0 °, the flexible display screen 12 is considered to be in the folded state.
The sensing unit is configured to include a deformation sensing unit. The deformation sensing unit may include a deformation sensor for sensing deformation information of the flexible display 12, but the present invention is not limited thereto. The deformation sensor may be provided in the flexible display 12. The deformation sensing unit is used for sensing an angle between the first flexible display screen 121 and the second flexible display screen 122 by sensing deformation information around the flexible display screen 12, particularly the first folding line 123, so that the control unit controls the transparency of the second flexible display screen 122 and the display state of the displayed image thereof according to the angle between the first flexible display screen 121 and the second flexible display screen 122. Specifically, the control unit may compare the information sensed by the deformation sensing unit with a preset angle value between the first flexible display screen 121 and the second flexible display screen 122 built in the system, and adjust the transparency of the second flexible display screen 122 and the display state of the displayed image according to the comparison result.
For example, when the angle between the first flexible display screen 121 and the second flexible display screen 122 is gradually decreased and decreased to the angle preset value of 90 °, the control unit starts to increase the transparency of the second flexible display screen 122 according to the comparison result, for example, increase the transparency of the second flexible display screen 122 to 10% when the angle between the first flexible display screen 121 and the second flexible display screen 122 is 90 °, and controls the second flexible display screen 122 to display a reverse image of the displayed image. When the angle between the first flexible display screen 121 and the second flexible display screen 122 is gradually increased and is increased to be greater than the angle preset value by 90 °, the control unit reduces the transparency of the second flexible display screen 122 according to the comparison result, and controls the image displayed by the second flexible display screen 122 to be changed from the inverted image to the normal display image.
In the present invention, increasing the transparency means that the flexible display 12 gradually changes from opaque to transparent, and decreasing the transparency means that the flexible display 12 gradually changes from transparent to opaque.
In the present invention, the normal display image is an image displayed in the unfolded state of the flexible display panel 12, and the reverse image is an image obtained by reversing the normally displayed image from left to right.
The flexible display 12 may comprise a Polymer Dispersed Liquid Crystal (PDLC) layer that can change its transparency by a change in an electrical signal applied thereto. In this example, by controlling the transparency of the PDLC layer, the control unit may control the image output from the flexible display 12 to be unrecognizable through another surface of the flexible display 12 or recognizable through another surface of the flexible display 12.
Specifically, when the angle between the first flexible display 121 and the second flexible display 122 of the flexible display 12 reaches the angle preset value, the flexible display 12 applies a specific voltage to the PDLC layer, thereby controlling the transparency of the flexible display 12.
Based on the transparency, the control unit activates the touch sensing layer provided on the back side of the second flexible display screen 122. For example, when the transparency of the second flexible display screen 122 is greater than 10%, the control unit may activate the touch sensing layer on the rear surface of the second flexible display screen 122 such that the touch sensing layer receives a touch input of a user. That is, when the angle between the first flexible display screen 121 and the second flexible display screen 122 is gradually decreased and reduced to the angle preset value, the control unit activates the touch sensing layer on the rear surface of the second flexible display screen 122. When the angle between the first flexible display screen 121 and the second flexible display screen 122 gradually increases and increases to be greater than a preset angle value, the control unit maintains the touch sensing layer on the back of the second flexible display screen 122 in a deactivated state. Accordingly, the user is prevented from receiving a touch input by the back of the flexible display 12 when the flexible display 12 is in the unfolded state.
In this embodiment, a touch sensing layer is also provided on the front surface of the flexible display 12. The touch sensing layer disposed on the front side of the flexible display 12 is used as a user input unit when the flexible display 12 is in the unfolded state, and the touch sensing layer disposed on the back side of the flexible display 12 is used as a user input unit when the flexible display 12 is in the folded state.
The control unit is configured to activate the flexible display 12 in accordance with a particular gesture input on the touch sensitive layer. The particular gesture may include a short (or tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch touch, a swipe touch, a hover touch, and the like.
The control unit is also configured to set preset functions for the hard display 11 and the flexible display 12, for example, the hard display 11 is set to display commonly used operation keys (e.g., navigation key, numeric keypad, alphabetic keypad, etc.) and display pages of a music player, answering a call, viewing time, short message, weather, calendar, etc. that do not require a large screen display function. The functions which do not need large screen display in the invention are those which have low requirements on the screen size, namely, the change of the size of the screen has little influence on the change of the user experience degree. The flexible display 12 is configured to display a page such as a picture, a video, a reader, etc. requiring a high function for a screen size, i.e., a function in which a change in size of the screen size greatly affects a change in user experience, and to operate an application installed later by the user, such as a WeChat, various types of video players, etc. According to the setting mode, the hard display screen 11 and the flexible display screen 12 are subjected to specific function division, so that the display content of the hard display screen 11 is not required to be changed when a user operates the mobile terminal, and the running speed and the user experience of the mobile terminal are improved.
In some embodiments of the present invention, the preset functions to which the hard display 11 and the flexible display 12 are set are not limited thereto, for example, the flexible display 12 and the hard display 11 may also be configured to: when a specific application is operated on the hard display screen 11, displaying an interface or an image corresponding to the application on the flexible display screen 12; alternatively, when a specific application is operated on the hard display 11, the desktop of the mobile terminal is displayed on the flexible display 12 (see fig. 6).
The sensing unit is further configured to include a gravity sensing unit. The gravity sensing unit may include a gyroscope, but the present invention is not limited thereto. The gravity sensing unit is used for sensing the direction of the display screen 10, so that the control unit adjusts the direction of the displayed image according to the direction of the display screen 10. For example, when the gravity sensing unit senses that the hard display screen 11 is horizontally placed, the control unit adjusts the display image of the hard display screen 11 to be horizontally displayed according to a signal of the gravity sensing unit. When the gravity sensing unit senses that the hard display screen 11 is longitudinally placed, the control unit adjusts the display image of the hard display screen 11 to be longitudinally displayed according to a signal of the gravity sensing unit. If the flexible display 12 displays images at the same time, the control unit controls the rigid display 11 to display images horizontally or vertically and also controls the flexible display 12 to display images horizontally or vertically.
Fig. 3 shows a schematic diagram of a first embodiment of a display image of the mobile terminal shown in fig. 1. Fig. 3 shows that a user activates the hard display screen 11 when the mobile phone is in a standby state, at this time, the user input unit of the mobile terminal generates an activation signal of the hard display screen 11 due to the input of the user and transmits the activation signal to the control unit, meanwhile, the gravity sensing unit senses that the hard display screen 11 is placed horizontally and transmits a corresponding signal to the control unit, and the control unit controls the hard display screen 11 to display preset information horizontally according to the activation signal of the hard display screen 11 and the signal of the gravity sensing unit. In this embodiment, the activation signal may be generated by pressing a physical key on the mobile terminal body, such as a power key, a navigation key, a talk key, and the like. The preset information displayed on the hard display screen 11 is time information, and understandably, the preset information displayed on the hard display screen 11 may also be weather information, main screen information of the mobile terminal, and the like. In the present embodiment, since the control unit does not receive the activation information of the flexible display 12, the flexible display 12 is not activated.
Fig. 4 shows a schematic diagram of a second embodiment of a display image of the mobile terminal shown in fig. 1. Fig. 4 shows that the hard display screen 11 is activated by an external incoming call when the mobile phone is in standby, at this time, the mobile communication unit of the mobile terminal generates an activation signal of the hard display screen 11 by receiving the external incoming call and transmits the activation signal to the control unit, meanwhile, the gravity sensing unit senses that the hard display screen 11 is horizontally placed and transmits a corresponding signal to the control unit, and the control unit controls the hard display screen 11 to transversely display incoming call information according to the activation signal of the hard display screen 11 and the signal of the gravity sensing unit. In the present embodiment, since the control unit does not receive the activation information of the flexible display 12, the flexible display 12 is not activated.

The front of the main body of the mobile terminal is also provided with a display screen 10. The display screen 10 also includes a rigid display screen 11 connected to the body, and a flexible display screen 12 connected to the rigid display screen 11. The flexible display 12 also includes a first flexible display 121 coupled to the rigid display 11 and a second flexible display 122 coupled to the first flexible display 121. A first folding line 123 is formed between the first flexible display screen 121 and the second flexible display screen 122.
Further, as shown in fig. 9, the first flexible display 121 includes a first divided screen 121a connected to the hard display 11, and a second divided screen 121b connecting the first divided screen 121a and the second flexible display 122, a second folding line 124 is formed between the first divided screen 121a and the second divided screen 121b, and the first flexible display 121 is foldable along the second folding line 124. The lengths of the first flexible display 121 and the second flexible display 122 are equal, and the sum of the lengths of the second flexible display 122 and the second split screen 121b is equal to the sum of the lengths of the first split screen 121a and the rigid display 11.
In this embodiment, the width of the display screen 10 is preferably 74mm, and the length is preferably 210mm. The total length of the flexible display 12 is preferably 130mm, the distance between the first folding line 123 and the free end of the second flexible display 122 is preferably 65mm, the distance between the second folding line 124 and the free end of the second flexible display 122 is preferably 105mm, that is, the length of the rigid display 11 is 80mm, the length of the first split screen 121a is 25mm, the length of the second split screen 121b is 50mm, and the length of the second flexible display 122 is 65mm.
When the flexible display 12 is folded along the second folding line 124, the second flexible display 122 of the flexible display 12 and the second split screen 121b of the first flexible display 121 cover the hard display 11 and the first split screen 121a of the first flexible display 121, and when the flexible display 12 is folded along the second folding line 124, the shape of the mobile terminal of the embodiment is the same as that of a common mobile terminal.
In the third embodiment, the control unit is further configured to sense an angle change of the first and second sub-screens 121a and 121b according to the deformation sensing unit around the second fold line 124, and control the PDLC layer to change the transparency of the first flexible display screen 121 according to the angle change. For example, when the angle between the first and second sub-screens 121a and 121b is gradually decreased and reduced to an angle preset value of 90 °, the control unit controls the PDLC layer to start to increase the transparency of the second sub-screen 121b, for example, to increase the transparency of the second sub-screen 121b by 10% when the angle between the first and second sub-screens 121a and 121b is 90 °. When the angle between the first and second sub-screens 121a and 121b is gradually increased and increased to more than 90 ° from the angle preset value, the control unit controls the PDLC layer to decrease the transparency of the second sub-screen 121 b. The preset angle value at the second folding line 124 may be equal to or different from the preset angle value at the first folding line 123. In the present embodiment, the preset angle value at the second folding line 124 is equal to the preset angle value at the first folding line 123.
The control unit is further configured to control a display state of an image displayed by the first flexible display screen 121 according to the angle change of the first and second sub-screens 121a and 121b sensed by the deformation sensing unit around the second fold line 124. For example, when the angle between the first and second split screens 121a and 121b is gradually reduced and reduced to an angle preset value of 90 °, the control unit controls the second split screen 121b to display a reverse image of the image displayed thereon. When the angle between the first and second sub-screens 121a and 121b is gradually increased and increased to be greater than the angle preset value by 90 °, the control unit controls the image displayed by the second sub-screen 121b to be changed from the reverse image to the normal display image.
The control unit is further configured to activate the touch sensing layer provided on the back of the first flexible display screen 121 based on the transparency of the first flexible display screen 121. For example, when the transparency of the second sub-screen 121b is greater than 10%, the control unit may activate the touch sensing layer on the rear surface of the second sub-screen 121b such that the touch sensing layer receives a touch input of a user. That is, when the angle between the first and second sub-screens 121a and 121b is gradually decreased and reduced to an angle preset value, the control unit activates the touch sensing layer on the rear surface of the second sub-screen 121 b. When the angle between the first and second sub-screens 121a and 121b is gradually increased and increased to be greater than a preset value of the angle, the control unit maintains the touch sensing layer at the back of the second sub-screen 121b in a deactivated state. Accordingly, the user is prevented from being received by a touch input at the back of the split screen when the split screen is in the expanded state.
In a third embodiment of the mobile terminal, the control unit may be configured to: when the flexible display 12 is in the fully folded state along the second folding line 124 and the mobile terminal is in the standby state, the second flexible display 122 and the second split screen 121b are controlled to be in the opaque state. When the mobile terminal is activated by an external input, the hard display screen 11 and the first split screen 121a are in a screen-off state, the control unit first controls the second flexible display screen 122 and the second split screen 121b to be in a completely transparent state according to a signal of the deformation sensing unit, and controls the second flexible display screen 122 and the second split screen 121b to reversely display a preset image. In this state, the second flexible display 122 and the second divided screen 121b display images as a whole.
In a third embodiment of the mobile terminal, the control unit may also be configured to: when the flexible display 12 is in the fully folded state along the second folding line 124 and the mobile terminal is in the standby state, the second flexible display 122 and the second split screen 121b are controlled to be in the fully transparent state. When the mobile terminal is activated by an external input, the hard display 11 and the first split screen 121a are in a screen-off state, the control unit first activates the second flexible display 122 and the second split screen 121b, and controls the second flexible display 122 and the second split screen 121b to reversely display a preset image according to a signal of the deformation sensing unit. In this state, the second flexible display 122 and the second split screen 121b display an image as a whole.
In the third embodiment of the mobile terminal, when the flexible display 12 is in the fully folded state along the first folding line 123, the display logic of the display 10 is identical to that of the first embodiment of the mobile terminal, and will not be described herein again.
The third embodiment of the mobile terminal can increase the working state of the mobile terminal by adding the second fold line 124 on the first flexible display screen 121, so that the operation and use modes of the mobile terminal are more diverse, and the mobile terminal can be conveniently stored.
It should be noted that, in this embodiment, the length of the first sub-screen 121a is 25mm, in other embodiments of the present invention, the length of the first sub-screen 121a may also be 0, and when the length of the first sub-screen 121a is 0, the flexible display screen 12 may be folded along the second folding line 124 and covered on the rigid display screen 11, so that when the angle between the flexible display screen 12 and the rigid display screen 11 is smaller than the preset angle value, the control unit may control to change the transparency of the entire flexible display screen 12 and control to reversely display the image displayed on the entire flexible display screen 12.
