It should be noted that other types of display panel (for example, organic LED display panel) is also likely to be present Figure 1B and shows Types of damage out.

At least one embodiment of the disclosure provide a kind of display control method, display control unit, display device and Storage medium.The display control method includes: the location information for obtaining the failure area of display panel；Position based on failure area Initial display is divided into image display area and non-image display area by confidence breath；And on the whole by image to be displayed It is shown at least two subgraph display areas.Display panel includes initial display, and failure area is located at initial aobvious Show in region；Failure area is located in non-image display area；And image display area includes by between non-image display area At least two subgraph display areas separated.Here, " by image to be displayed on the whole at least two subgraph display areas Shown " it indicates substantially in tact to show image to be displayed at least two subgraph display areas.

In some instances, by the way that the initial display of display panel is divided into image display area and non-image aobvious Show region, and image to be displayed is shown at least two subgraph display areas on the whole, it can be by image to be displayed It is shown on the whole in the non-failure area of display panel, thus improve the usage experience of user and/or reduces resource wave Take.

Unrestricted theory is carried out to the display control method provided according to the embodiment of the present disclosure below by several examples Bright, as described below, different characteristic can be combined with each other in these specific examples in not competing situation, thus New example is obtained, these new examples also belong to the range of disclosure protection.

A kind of exemplary process diagram for display control method that at least one embodiment that Fig. 2A shows the disclosure provides. The display control method can be used for controlling the display panel, and show for example, the display panel can be used for computer, mobile phone, navigator etc. In showing device.As shown in Figure 2 A, which includes the following steps.

Step S100: obtaining the location information of the failure area 101 of display panel, and failure area 101 is located at initial display In region.

Step S200: initial display 110 is divided into image display area by the location information based on failure area 101 With non-image display area.

Failure area 101 is located in non-image display area and image display area includes by non-image display area At least two subgraph display areas 102 spaced apart.

Step S300: image to be displayed is shown at least two subgraph display areas 102 on the whole.Display surface Plate includes initial display 110.

Fig. 2 B shows the display panel 100 and image to be displayed 111 that at least one embodiment of the disclosure provides.Such as Shown in Fig. 2 B, display panel 100 includes initial display 110, and initial display 110 is, for example, display panel 100 not There are the display areas in the case of local damage.Initial display 110 is X in the size of line direction, ruler in a column direction Very little is Y.Image to be displayed 111 is M in the size of line direction, and the size of image to be displayed 111 in a column direction is N.For example, X, Y, the unit of M and N can be number of pixels, and in such cases, the value of X, Y, M and N are the positive integer being not zero.

Fig. 3 A shows a kind of schematic diagram of initial display 110 of display panel, and initial display 110 has row Direction (that is, first direction D1 in Fig. 3 A) and column direction (that is, second direction D2 in Fig. 3 A).As shown in Figure 3A, should Initial display 110 includes having the non-image display area of failure area 101 and being spaced apart by non-image display area Two sub- image display areas 102.In the example shown in Fig. 3 A, non-image display area is overlapped with failure area.

As shown in Figure 3A, initial display 110 is in rectangle, and each subgraph display area 102 is in rectangle, thus It can simplify the operand of display control method.It will be in below square with initial display 110 and subgraph display area 102 Each example of the disclosure is illustrated for shape, but embodiment of the disclosure is without being limited thereto.According to practical application need It asks, the shape of initial display 110 and subgraph display area 102 may be arranged as other shapes, no longer superfluous herein It states.

The concrete type of the location information of the failure area 101 of display panel can be set according to practical application request Fixed, embodiment of the disclosure is not specifically limited in this embodiment.

In one example, the location information for obtaining the failure area 101 of display panel includes: to obtain failure area 101 Start of line position (for example, X1) in the row direction and row end position (for example, X2) in initial display 110, and Obtain column initial position (for example, 0) and column end position of the failure area 101 in initial display 110 in a column direction (for example, Y).

In another example, the location information for obtaining the failure area 101 of display panel includes: acquisition failure area 101 start of line position (for example, X1) and failure area 101 in initial display 110 in the row direction is in the row direction Size (for example, X0)；And obtain column initial position of the failure area 101 in initial display 110 in a column direction The size (for example, Y0=Y) of (for example, 0) and failure area 101 in a column direction.

In another example, the location information for obtaining the failure area 101 of display panel includes: acquisition failure area The 101 row end position (for example, X2) and failure area 101 in initial display 110 in the row direction is in the row direction Size (for example, X0)；And obtain column end position of the failure area 101 in initial display 110 in a column direction The size (for example, Y0=Y) of (for example, Y) and failure area 101 in a column direction.

For example, can be before executing step S100 (that is, believing in the position for obtaining the failure area 101 of display panel Before breath), it can be with the location information of the failure area 101 of input display panel, the position of the failure area 101 of input display panel The specific method of confidence breath can be set according to practical application request, and embodiment of the disclosure is not specifically limited in this embodiment. In one example, the location information of failure area 101 in interactive interface input display panel can be used, in such cases, The display control method further includes providing interactive interface to allow the position of failure area 101 in user's input display panel to believe Breath.In another example, it is also based on the location information of the failure area 101 of image procossing input display panel.Again In one example, it is also based on the location information of the failure area 101 of screenshot input display panel.

Below with reference to Fig. 4 A- Fig. 4 C to using the location information of failure area 101 in interactive interface input display panel Method illustrates.Fig. 4 A- Fig. 4 C provides three kinds of interactive boundaries for determining the failure area shown in Fig. 3 A- Fig. 3 C The schematic diagram in face.For example, interactive interface includes that movable cursor is selected with allowing the mobile cursor of user as shown in Fig. 4 A- Fig. 4 C Select the start of line position in initial display 110 in the row direction of failure area 101 and row end position, and/or selection Column initial position and column end position of the failure area 101 in initial display 110 in a column direction.

It in one example, as shown in Figure 4 A, is the strip failure area 101 extended along column direction in failure area 101 In the case where, which can show that the adjustable lines a1 and b1 in two display positions, user can be by above-mentioned two The adjustable lines in position are moved to the boundary (side of failure area 101 in the row direction of the failure area 101 of display panel Boundary), it is possible thereby to which the coordinate information based on adjustable lines a1 and b1 determines failure area 101 in initial display 110 In start of line position X1 and row end position X2 in the row direction, and failure area 101 can be determined in initial viewing area Column initial position Y1 and column end position Y2 in domain 110 in a column direction are respectively 0 and Y (referring to Fig. 3 A).

It in another example, as shown in Figure 4 B, is the strip failure area 101 that line direction extends in failure area 101 In the case where, which can show that the adjustable lines c1 and d1 in two display positions, user can be by above-mentioned two The adjustable lines in position are moved to the boundary (side of failure area 101 in a column direction of the failure area 101 of display panel Boundary), it is possible thereby to which the coordinate information based on adjustable lines c1 and d1 determines failure area 101 in initial display 110 In column initial position Y1 and column end position Y2 in a column direction, and failure area 101 can be determined in initial viewing area Start of line position X1 and row end position X2 in domain 110 in the row direction are respectively 0 and X (referring to Fig. 3 B).

It is blocky failure area 101 or irregular damage in failure area 101 as shown in Figure 4 C in another example In the case where error area 101, which can show four display positions adjustable lines a1, b1, c1 and d1, user The adjustable lines in above-mentioned four positions can be moved to the boundary of the failure area 101 of display panel, and it is possible thereby to base The side of being expert in initial display 110 of failure area 101 is determined in the coordinate information of adjustable lines a1, b1, c1 and d1 Upward start of line position X1, row end position X2, column initial position Y1 and column end position Y2 (referring to Fig. 3 C).

It, can in the case where determining start of line position X1, row end position X2, column initial position Y1 and column end position Y2 To determine the size X0=X2-X1 of failure area 101 in the row direction, and determine the ruler of failure area 101 in a column direction Very little Y0=Y2-Y1.Therefore, by above-mentioned method, the damage of the input display panel of simple, intuitive can be enabled a user to The location information in region 101.

For example, (OSD MENU) interactive interface can be increased in the setting interface of display panel, to allow user to input The location information of failure area 101 in display panel.It is, for example, possible to use the setting interfaces of display panel, and by following The location information of failure area 101 in step input display panel.Firstly, into the setting interface of display panel, and open and set The function in demarcation face adjusts switch；Secondly, the color of the adjustable lines in setting position and the color to be filled of failure area； Again, the number of the cross-wise lines needed and the number of vertical lines are selected.Herein, cross-wise lines are along the position that line direction extends Adjustable lines are set, and the position of cross-wise lines in a column direction is adjustable；Vertical lines are along the position that column direction extends Adjustable lines, and the vertical position of lines in the row direction is adjustable.4th, the position of adjustment cross-wise lines in a column direction The position of vertical lines in the row direction is set and/or adjusts, so as to be located at failure area corresponding for the adjustable lines in position Boundary.Finally, above-mentioned setting is saved, with the location information of failure area 101 in input display panel.For example, by showing Increase interactive interface in the setting interface of panel, can use the existing functional module of display panel, it is possible thereby to reduce display The development amount of control method.

Exemplary theory is done to the location information of the failure area 101 of the method input display panel by image procossing below It is bright.In such cases, display control method include thes steps that following S410 and step S420.

Step S410: the test image for the test pictures that initial display 110 is shown is obtained.

Step S420: the location information of the failure area 101 of display panel is obtained based on test image.

For example, that there are dim spots is bad (that is, the display pixel of failure area 101 cannot for the failure area 101 of display panel Shine, even if when the predetermined gray scale of the display pixel of failure area 101 is not zero) in the case where, display panel can be made In complete white display pattern, the survey for the picture (that is, test pictures) that initial display 110 is shown then is obtained using camera Attempt picture；In such cases, for example, the gray scale of the image-region corresponding to failure area 101 of test image is less than test chart The gray scale in other regions of picture.In another example that there are bright spots is bad (that is, failure area 101 for the failure area 101 of display panel Display pixel continuous illumination, even if when the predetermined gray scale of the display pixel of failure area 101 is zero) in the case where, can be with So that display panel is in completely black display pattern, then using camera obtain picture that initial display 110 shows (that is, Test pictures) test image；In such cases, for example, the ash of the image-region corresponding to failure area 101 of test image Degree is greater than the gray scale in other regions of test image.It should be noted that above example is with the gray scale of image pixel and to be somebody's turn to do Embodiment of the disclosure is illustrated for the gamma correction that image pixel indicates is related, but embodiment of the disclosure is not It is limited to this.For example, the brightness that the gray scale of image pixel can also be indicated with the image pixel is negatively correlated, in such cases, When the failure area 101 of display panel is bad there are dim spot, the image-region corresponding to failure area 101 of test image Gray scale is greater than the gray scale in other regions of test image；When the failure area 101 of display panel is bad there are bright spot, test chart The gray scale of the image-region corresponding to failure area 101 of picture is less than the gray scale in other regions of test image.

For example, being included the following steps based on the location information that test image obtains the failure area 101 of display panel S421 and step S422.

Step S421: to test image carry out image procossing, with search test image correspond to initial display 110 In failure area 101 image-region.

Step S422: the position corresponding to the image-region of failure area 101 in test image based on test image Obtain the location information of the failure area 101 of display panel.

For example, can search test image by the methods of pattern-recognition corresponds to damage area in step S421 The image-region in domain 101.For example, grayscale information can be extracted in test image, it is then based on grayscale information and searches test chart The image-region corresponding to failure area 101 of picture.For example, in step S422 damage can be corresponded to based on test image The coordinate of the image-region of error area 101 come determine display panel failure area 101 location information (for example, failure area 101 start of line position X1 and row end position X2 in initial display 110 in the row direction).

For example, the location information of the failure area 101 by the method input display panel of image procossing, can be promoted and be obtained The degree of automation with the location information of the failure area 101 of input display panel is taken, at this point, can not only promote making for user With experience, it can also be obtained before for example each opening display device and the position of the failure area 101 of input display panel is believed Breath, it is possible thereby to change the location information of the failure area 101 of display panel in time in the failure area variation of display panel, It is possible thereby to further promote display effect.

Exemplary theory is carried out to the method for the location information of the failure area 101 based on screenshot input display panel below It is bright.In such cases, display control method include thes steps that above-mentioned S410 and step S420, and step S420 is (that is, be based on Test image obtains the location information of the failure area 101 of display panel) include the following steps (for showing shown in Fig. 3 A Example).

It is possible, firstly, to intercept the image of failure area 101 and the figure of the display area positioned at 101 left side of failure area Picture；It is then possible to the ratio in the row direction of image and initial display 110 based on failure area 101, and damage The image of the display area in the left side of region 101 and the ratio in the row direction of initial display 110 determine failure area 101 start of line position, row end position, column initial position and column end position；Finally, can with line of input initial position, Row end position, column initial position and column end position.

For example, in step s 200, initial display 110 is divided into figure by the location information based on failure area 101 As display area and non-image display area include the following steps S210.

Step S210: by initial display 110 between the start of line position of failure area 101 and row end position it Between region and the region between column initial position and the column end position of failure area 101 be determined as non-image display Region.

For example, as shown in Figure 3A, in the case where failure area 101 is along the strip failure area 101 that column direction extends, It can be using following 4 points of rectangles surrounded as non-image display area: (X1,0), (X2,0), (X2, Y) and (X1, Y)；Also, The display area of the two sides (two sides in the row direction) of strip failure area 101 can be determined as image display area.

For example, as shown in Figure 3B, in the case where failure area 101 is along the strip failure area 101 that line direction extends, Following 4 points figures (for example, rectangle) surrounded can be used as to non-image display areas: (0, Y1), (X, Y1), (X, Y2) and (0, Y2)；And it is possible to which the display area of the two sides (two sides in a column direction) of strip failure area 101 is determined as image Display area.

For example, being blocky failure area 101 as shown in Fig. 3 C and Fig. 4 C in failure area 101 or irregularly damaging area In the case where domain 101, the following 4 points figures (for example, rectangle) surrounded can be regard as non-image display area: (X1, Y1), (X2, Y1), (X2, Y2) and (X1, Y2)；And can at least based on comparison failure area 101 two sides display area face Long-pending method determines image display area.For example, as shown in Figure 3 C, the viewing area of the two sides of failure area 101 in the row direction The sum of the area in domain is greater than the sum of the area of display area of two sides of failure area 101 in a column direction, therefore can will damage The display area of the two sides of error area 101 in the row direction is determined as image display area, so that for showing figure to be shown The sum of area of image display area of picture maximum.It should be noted that in other examples, determining image display area When, it can be combined with considering the area of display area and the length-width ratio of display area.

For example, initial display 110 has the first display resolution R1=(Rx:Ry)=(X:Y)；Image display area Image to be displayed is shown herein on the whole with the second display resolution R2=(Rx1:Ry1), Rx and Ry are initially to show respectively Resolution ratio of the region 110 on line direction and column direction, Rx1 and Ry1 are image to be displayed respectively on the whole in line direction and column Resolution ratio on direction.For example, can based on image display area it is whole with initial display 110 length ratio LR (that is, Dimension scale in the row direction) and width ratio WR (that is, dimension scale in a column direction), it is obtained by the first display resolution To the second display resolution R2=(Rx1:Ry1), for example, Rx1=Rx × LR, Ry1=Ry × WR.

For example, the display area shown in for Fig. 3 A and Fig. 3 C, image display area entirety and initial display 110 Length ratio LR=(X-X0)/X and width ratio WR=1, it is hereby achieved that the second display resolution R2=(Rx1:Ry1), herein, Rx1=X × (X-X0)/X=X-X0, Ry1=Y × 1=Y.

For example, the display area shown in for Fig. 3 B, the whole length ratio with initial display 110 of image display area LR=1 and width ratio WR=(Y-Y0)/Y, it is hereby achieved that the second display resolution R2=(Rx1:Ry1), herein, Rx1=X × 1=X, Ry1=Y × (Y-Y0)/Y=Y-Y0.

For example, the display control method can also include the following steps S500: processing is zoomed in and out to image to be displayed, With the image to be displayed after being scaled.

For example, in step S500, it is possible, firstly, to obtain image to be displayed in line direction based on the second display resolution Scale multiple HS and scaling multiple VS in a column direction；Secondly, can based on image to be displayed line direction scaling times Number HS and scaling multiple VS in a column direction zoom in and out processing to image to be displayed, to obtain having the second display resolution Image to be displayed after the scaling of rate.

For example, the size in the size and column direction in the row direction of the image to be displayed of signal source output is respectively M In the case where N, image to be displayed meets respectively in the scaling multiple HS and scaling multiple VS in a column direction of line direction Following equations: HS=Rx1/M；VS=Ry1/N.For example, the scaling method that can be used includes interpolation method (for example, two-wire Property interpolation method or closest interpolation method).

For example, the display control method can also include the following steps S600: the division based on initial display 110 Information will correspondingly be divided at least two display subgraphs on image to be displayed position.

It, will be on the image to be displayed position after scaling based on the division information of initial display 110 in step S600 Correspondingly being divided at least two display subgraphs includes: that the image to be displayed after scaling is divided at least two displays Image.

For example, step S600 can be executed after step S500, in such cases, show that the number of subgraph is equal to son The number of image display area 102, and the size of each display subgraph is equal to the ruler of corresponding subgraph display area 102 It is very little.For example, the shape of each display subgraph is equal to the shape of corresponding subgraph display area 102.It should be noted that In the case that display subgraph and subgraph display area 102 are rectangle, the size of each display subgraph is equal to corresponding The size of subgraph display area 102 refers to that the length of each display subgraph is equal to corresponding subgraph display area 102 Length, and the width of each display subgraph is equal to the width of corresponding subgraph display area 102.In display subgraph and son In the case that image display area 102 is other shapes, show that the size of subgraph is the circle referred to around display subgraph The minimum dimension of shape, the size of subgraph display area 102 also have similar meaning, and details are not described herein.

It should be noted that according to practical application request, it is also possible that step S600 is executed before step S500, That is, being first at least two display subgraphs to image segmentation to be shown, then by least two display subgraphs according to identical Scaling multiple zooms in and out respectively；In such cases, show that the number of subgraph is equal to the number of subgraph display area 102, And the size of each display subgraph is steady state value with the ratio of the size of corresponding subgraph display area 102, so that After being zoomed in and out using identical scaling multiple at least two display subgraphs, at least two display each of subgraphs with Corresponding subgraph display area 102 can be substantially overlapped, and details are not described herein.

For example, the display control method can also include the following steps S700: obtaining each display of image to be displayed The coordinate correspondence relationship of subgraph and corresponding subgraph display area 102.

For example, in step S700, each display subgraph of image to be displayed and corresponding subgraph viewing area are obtained The coordinate correspondence relationship in domain 102 includes the following steps S710 and step S720.

Step S710: the coordinate of the first reference point of each display subgraph is obtained.

Step S720: obtaining the coordinate of the second reference point of the corresponding subgraph display area 102 of each display subgraph, Herein, the first reference point is shown during display by the second reference point of subgraph display area 102.

For example, the first reference point can be the upper left image pixel of each display subgraph, the second reference point can be with It is the upper left display pixel of each subgraph display area 102.

For example, the example shown in for Fig. 3 A and Fig. 3 C, positioned at the subgraph display area 102 in 101 left side of failure area The coordinate of the second reference point be (0,0), and be located at the second reference of the subgraph display area 102 on the right side of failure area 101 The coordinate of point is (X1+X0,0).For example, the example shown in for Fig. 3 B, positioned at the subgraph viewing area of 101 upside of failure area The coordinate of second reference point in domain 102 is (0,0), and is located at second of the subgraph display area 102 on the downside of failure area 101 The coordinate of reference point is (0, Y1+Y0).

It will be understood by those skilled in the art that after obtaining the coordinate of the first reference point of each display subgraph, When at least two display subgraphs are shown at least two subgraph display areas respectively, each display can be made First reference point of subgraph shows by the second reference point of corresponding subgraph display area 102, and by each display Other image pixels of image are shown by the other display pixels for corresponding to subgraph display area, so that each subgraph Display area can completely show corresponding display subgraph.For example, equal in display subgraph and subgraph display area 102 In the case where rectangle, those skilled in the art are aobvious in the upper left display pixel using each subgraph display area 102 While showing the upper left image pixel of corresponding display subgraph, the right side of each subgraph display area 102 also will use The display pixel of top, lower left and lower right shows upper right side, lower left and the lower right of corresponding display subgraph respectively Image pixel it is no longer superfluous herein so that each subgraph display area can completely show corresponding display subgraph It states.

It should be noted that above example with obtain it is each display subgraph single reference point coordinate come obtain to Show each display subgraph and the coordinate correspondence relationship of corresponding subgraph display area 102 of image, but the reality of the disclosure It is without being limited thereto to apply example.For example, according to practical application request, it can also be for the multiple reference points of acquisition of each display subgraph The coordinate on (for example, using four vertex of each display subgraph as four reference points), details are not described herein.
