In practical application, the electronic device may be a smart watch, a smart band, a smart headset device, a smart phone, or a tablet computer, etc, and is not enumerated according to the embodiment.
In a specific implementation process, the display unit may be a flexible display screen, or a thin display screen with certain flexibility, which is capable of being bended with certain curvature.
The method for processing information provided according to the embodiment of the disclosure may not only be applied to a case that a still image is displayed on a bending display unit, but also be applied to a case that a dynamic video image is displayed on the bending display unit, and is not limited according to the embodiment.
The method for processing information provided according to the first embodiment is described step by step in detail in the following together with FIG. 1.
First, in step S101, once notification signal for notifying the electronic device that a first plane image needs to be displayed is received, a current bending state parameter for characterizing a current bending state of the display unit are detected and obtained based on the notification signal.
In a specific implementation process, the notification signal may be generated in response to selection operation after the selection operation for selecting the first plane image is received.
For example, the notification signal may be generated after the user clicks and selects the first plane image pre-stored in a picture library.
Alternatively, the notification signal may be generated in response to switching operation after the switching operation for switching to a display effect optimization mode is received,
Notification signal generated after the user clicks a preset button of the electronic device or the display effect optimization mode is selected to be entered from setting options of the electronic device. In this case, the first plane image is a current displaying image of the display unit of the electronic device.
According to the embodiment of the disclosure, to accurately characterize the bending state of the display unit, the current bending state parameters include at least a bending position parameter for characterizing a position for a bending area of the display unit which is in a bending state currently, and a current bending radian parameter of the bending area.
In a specific implementation process, the current bending state parameters may be obtained through at least two following ways, one is to dispose a pressure sensor array inside the display unit, and the other is to dispose a mutual inductance unit, which are described in detail in the following.
The first way is to dispose the pressure sensor array inside the display unit.
As shown in FIG. 2, the pressure sensor array may be disposed on a display layer 201 on a surface of the electronic device, on an elastic layer 202 between the display layer 201 and components of the electronic device, and a pressure sensing unit layer 203 between the display layer 210 and the elastic layer 202.
In a specific implementation process, the elastic layer 202 may be made of material with elastic force changing with bending degree, such as thermoplastic elastomer or rubber.
In a specific implementation process, multiple pressure sensing units 204 may be disposed on a surface of the pressure sensing unit layer 203, which faces the elastic layer 202, so that the pressure sensing units 204 are capable of receiving pressure from the elastic layer 202 when the elastic layer 202 is bended as the display layer 201 is bended.
According to the embodiment of the disclosure, in a case that the pressure sensing units are disposed inside the display unit, the process of obtaining the current bending state parameters for characterizing a current bending state of the display unit includes:

    
    
        obtaining, through the pressure sensing units 204, parameters of current pressure from the display layer 201 and the elastic layer 202 on the pressure sensing units; and
        calculating the current bending state parameters for characterizing the current bending state of the display unit based on the current pressure parameters.
    
    


A calculation method for the current bending state parameters of the display unit is illustrated in conjunction with FIG. 3 in the following.
It is assumed that the current pressure parameter received by a first sensing unit 301 disposed on the pressure sensing unit layer 203 is F, a bending degree parameter of a first display area 302 to which a distance from the first sensing unit 301 is smaller than a threshold may be obtained through the following mechanics formula:




  
    θ
    =
    
      
        F
        ⁢
        
          
        
        ⁢
        
          l
          2
        
      
      
        2
        ⁢
        
          
        
        ⁢
        E
        ⁢
        
          
        
        ⁢
        l
      
    
  
  ,




    
    
        where as shown in FIG. 3, θ is the bending degree of the first display area 302 with respect to a predetermined display area 303 of the display unit, l is a distance between the first display area 302 and the predetermined display area 303 on the bending surface of the display unit, and EI is known stiffness of the elastic layer 202.
    
    


Through the calculation method, the current bending state parameters for any area of the display unit which is disposed with the pressure sensing unit may be calculated.
Specifically, the way, in which the current bending state parameters of the display unit is obtained through disposing the pressure sensing units inside the display unit, has low calculation amount, has no need to perform calculation with large calculation amount such as three-dimensional reconstruction, may improve display efficiency, and is more applicable to display video images.
The second way is to dispose the mutual inductance units inside the display unit.
Referring to FIG. 4, as shown in FIG. 4, multiple mutual inductance units 401 are disposed inside the display unit. Each mutual inductance unit may be configured to be capable of sensing relative distances and relative orientations of the other mutual inductance units, alternatively, a sensor module may be disposed inside the electronic device, and relative distances and relative orientations of each mutual inductance unit are acquired through the sensing module.
After coordinate data including relative distances and relative orientations for each mutual inductance unit is acquired, current coordinate point for each mutual inductance unit may be labeled in a preset three dimension coordinate axis through the coordinate data.
According to the current coordinate point for each mutual inductance unit, the bending state of the display unit may be obtained and the current bending state parameters may be obtained through a structure from motion (SFM) algorithm and/or a trend simulation algorithm.
In a specific implementation process, the mutual inductance units may be wireless units which are capable of transmitting and receiving wireless signal to each other, alternatively, the mutual inductance units may be magnetic units magnetically attracted to each other, and are not limited according to the embodiment.
In a specific implementation process, ways for obtaining the current bending state parameters are not limited to the two foregoing ways, alternatively, the current bending state parameters of the display unit may be obtained through collecting a current image of the display unit by using an image acquisition unit of the electronic device, and the ways are not limited according to the embodiment.
After the current bending state parameters are obtained through step S101, step S102 is executed to acquire the first plane image from memory.
Specifically, after the notification signal for notifying the electronic device that the first plane image needs to be displayed is received, the first plane image may be stored in memory in term of pixels according to the size of the display area of the display unit, thereby facilitating subsequent image processing for the first plane image.
After the current bending state parameters are obtained, an image processing unit may read the first plane image from the memory, alternatively, the image processing unit may receive the first plane image which is read from the memory and transmitted to the image processing unit by other units, which is not limited according to the embodiment.
In step S103 and step S104, image processing is performed on the first plane image to obtain the second image according to the current bending state parameters; transmitting the second image to video memory of the display unit, to make a projected image of the second image on a preset plane is the same as the first plane image when the second image is displayed on the display unit in a curved surface shape.
In a specific implementation process, the user often views images displayed on the display unit from a direction facing the display unit, therefore the preset plane is set as a plane facing the display unit.
In a specific implementation process, the process of performing image processing on the first plane image according to the current bending state parameters may include following two image processing ways.
The first way is to perform local stretch processing, local rotation processing and/or local shift processing according to the current bending state parameters.
That is, local stretch processing, local rotation processing and/or local shift processing is performed on the first plane image according to the current bending state parameters, and interpolation processing is then performed on the first plane image through the k-means algorithm or the trend simulation algorithm to obtain the second image with good continuity.
Referring to FIG. 5, in order that on a preset plane 503, projection of the second image 502 displayed on the display unit 501 is the same as the first plane image 504, as shown in FIG. 5, the first way includes:

    
    
        performing stretch processing on a first line 505 on the first plane image 504 according to the bending state parameters of the display unit 501;
        performing interpolation processing on the stretched first line 505 according to an interpolation algorithm to generate a continuous line 506, thereby generating the second image 502; and
        transmitting the second image 502 to video memory of the display unit 501, so that the display unit 501 displays the second image 502, and on the preset plane 503, projection of the displayed second image 502 is the same as the first plane image 504.
    
    


When a user faces the display unit 501, he/she may acquire, through the bending display unit 501, content of the first plane image 504 instead of content of the first plane image 504 with bending deformation. Therefore, visual effects and user experience can be improved.
The second way is to locally enlarge or locally shrink the stretched and/or rotated image.
In a specific implementation process, for lines with a same thickness displayed on the display unit, the user senses that a line in an area closer to the he/she is thicker than that in an area farther from he/she, therefore for sensing original thickness of the line without affection of distances to the display areas, the second image may be locally enlarged or locally shrinked.
That is, after the interpolation processing is performed on the first plane image to obtain the second image through the k-means algorithm or the trend simulation algorithm, the method further includes:

    
    
        in a concave area of the surface of the display unit, performing local zoom processing on the second image according to the current bending state parameters and preset display position parameters for characterizing a display position of the second image on the display unit, so that the display size of the second image displayed on the display unit gradually decreases along a direction from a vertex of the concave area to a endpoint of the concave area; and
        in a convex area of the surface of the display unit, performing local zoom processing on the second image according to the current bending state parameters and the display position parameters, so that the display size of the second image displayed on the display unit gradually increases along a direction from a vertex of the convex area to a endpoint of the convex area.
