An embodiment of the present invention provides a flexible display panel 100, as shown in fig. 1, the flexible display panel 100 includes a bending region 30 and a non-bending region 20. The bending region 30 is an area where the flexible display panel 100 can be bent and is shown as a curved surface. The non-bending region 20 refers to a region of the flexible display panel 100 that is a plane when displayed.
Referring to fig. 1, fig. 2 and fig. 3, the flexible display panel 100 further includes a plurality of pixel units P arranged in an array, where each pixel unit P may include k sub-pixels, and k is an integer greater than 0. The non-inflection region 20 requires a resolution of m × n, where m and n are integers greater than 1. That is, the non-bending region 20 can display m rows and n columns of pixel units P. That is, the display screen can be displayed by m × n pixel units. The required resolutions are 600 × 800, 796 × 1024, 1024 × 2048, 1680 × 1050, 1920 × 1200, 2560 × 1600, and so on.
With continued reference to fig. 1, 2 and 3, the flexible display panel 100 includes a display area AA and a non-display area NA, wherein the actual resolution of the display area AA ranges from (m-2a) × (n-2b) to (m +2a) × (n +2b), and a and b are integers greater than 0. That is, the actual resolution of the display area AA is adjusted to any value of (m-2a) × (n-2b) and (m +2a) × (n +2 b). The actual display line number of the display area AA is not more than m +2a lines and is not less than m-2a lines; the display area AA actually displays no more columns than n +2b rows, not less than n-2b rows. The actual resolution of the display area AA is that a lines are respectively reduced from the upper part to the lower part of the required resolution line number to be respectively increased from the upper part to the lower part; the actual resolution of the display area AA is b columns decreased from left to right to b columns increased from left to right, respectively, of the number of columns of the required resolution. The display area AA includes a blurred display area 50 and a non-blurred display area 40, and the blurred display area 50 is disposed around the non-blurred display area 40.
According to the flexible display panel 100 provided by the embodiment of the invention, the range of the actual resolution of the display area AA is calculated according to the required resolution of the non-bending area 20, so that the display range of the display area AA can be adjusted, the problem of poor display caused by attachment and dislocation of the bending area 30 is solved, and the frame area of the flexible display panel 100 is not increased.
Further, as shown in fig. 2 and 3, the resolution of the non-ghosted display region 40 is (m-2a) × (n-2 b). That is, (m-2a) × (n-2b) pixel cells are not subjected to the blurring display, that is, normal display data is input to the (m-2a) × (n-2b) pixel cells in the non-blurring display area 40. That is, the required resolution row number of the display area AA is reduced by a rows up and down, and the required resolution column number of the display area AA is reduced by b columns left and right, so that the normal display is performed. Further, the middle area for displaying AA can be selected for normal display, and as shown in fig. 3, the pixel unit P in the 2a +1 th row and the 2b +1 th column, the pixel unit P in the 2a +1 th row and the n-th column, the pixel unit P in the m-th row and the 2b +1 th column, and the m-th row and the n-th column form four vertices of the non-blurred display area 40, so that a rectangular area formed by the four vertices is the non-blurred display area 40.
Further, with continued reference to fig. 2 and fig. 3, the pixel units P in the rows 1 to 2a, the pixel units in the rows m +1 to m +2a, the pixel units in the columns 1 to 2b, and the pixel units in the columns n +1 to n +2b are located in the blurring display area 50.
For convenience of understanding, the required resolution of the non-bending region 20 is 800 × 600, a =10, and b = 10. Referring to fig. 1, fig. 2 and fig. 3, the required resolution of the non-bending area 20 of the flexible display panel 100 is 800 × 600, and the actual resolution of the display area AA ranges from 820 × 620 to 780 × 580. To achieve the actual resolution range, the pixel unit P of the display area AA of the flexible display panel 100 at least includes 820 rows and 620 columns. The pixel units P in the rows 1 to 20, 801 to 820, 1 to 20, 601 to 620 are displayed in a blurred manner, that is, the pixel units P in the rows 1 to 20, 801 to 820, 1 to 20, 601 to 620 are in the blurred display area 50. The non-virtual display area 40 is a rectangular area formed by the pixel unit P in the 21 st row and the 21 st column in the 21 st row, the pixel unit P in the 21 st row and the 21 st column in the 800 th row, the pixel unit P in the 600 th column in the 21 st row, and the pixel unit P in the 600 th column in the 800 th row as vertexes. I.e. the resolution of the non-blurred display area is 780 x 580.
If the bending region 30 has a misalignment, for example, it is shifted inward by 10 rows in the upper, lower, left and right directions. The actual resolution of the display area AA is 780 × 580, and the non-blurred display area 50 is displayed exactly at this time.
If the bending region 30 has a misalignment, for example, it is shifted 10 rows outward from the upper, lower, left, and right sides. The actual resolution of the display area AA is 820 × 620, in which case both the non-ghosted display area 50 and the ghosted display area 40, which are just the display area AA, are fully displayed. Since the display of the pixel unit P of the non-pixilated display 50 is a transitional display, it is not visually obtrusive.
If the misalignment of the bending region 30 is within the above-mentioned offset range, the non-blurred display region 40 and a portion of the blurred display region 50 are completely displayed. Since the display of the pixel unit P of the non-pixilated display 50 is a transitional display, it is not visually obtrusive.
In summary, according to the flexible display panel 100 provided in the embodiment of the present invention, since the non-virtualized display area and the virtualized display area are determined, normal display of the flexible display panel 100 can be satisfied within the maximum deviation range, and a frame of the flexible display panel 100 when actually disposed is not increased.
Further, as shown in fig. 4, the width of the pixel unit P of the flexible display panel 100 is q micrometers, and q and a satisfy the relationship: 2a × q ≦ 300. The range of the virtual display area 50 cannot be expanded infinitely, so the size of the range of the virtual display area 50 of the flexible display panel 100 needs to be designed. The alignment deviation of the bending region 30 is controlled within 300 μm, and the value range of a, i.e. the conversion range of the number of rows, is determined according to the difference of the widths of the pixel units P of the flexible display panel 100. Therefore, when normal display is ensured when the alignment deviation occurs, the range of the actual resolution of the display area AA is increased, and the ratio of the display area AA of the flexible display panel 100 is further increased.
With reference to fig. 4, the length of the pixel unit P of the flexible display panel 100 is P micrometers, and P and b satisfy the relationship: 2b × p ≦ 300. The range of the virtual display area 50 cannot be expanded infinitely, so the size of the range of the virtual display area 50 of the flexible display panel 100 needs to be designed. The alignment deviation of the bending region 30 is controlled within 300 micrometers, and the value range of b, that is, the conversion range of the number of columns, is determined according to the difference of the lengths of the pixel units P of the flexible display panel 100. Therefore, when normal display is ensured when the alignment deviation occurs, the range of the actual resolution of the display area AA is increased, and the ratio of the display area AA of the flexible display panel 100 is further increased.

The length of the sub-pixel R is c micrometers, and the distance between the sub-pixels R of the adjacent rows is d micrometers, so that the distance from the upper end of the pixel unit P to the upper end of the next pixel unit P is 3 × (c + d), and thus the width of the pixel unit P of the 2a row is 2a × 3 × (c + d). The width of the 2a rows of pixel cells P is no greater than 300 microns.
With reference to fig. 5, the width of the sub-pixel R is e micrometers, the distance between the sub-pixels R in adjacent columns is f micrometers, and b, k, e, and f satisfy the following relationship: 2b × (e + f) ≦ 300. The width of the sub-pixel R is e micrometers, the distance between the sub-pixels R of adjacent columns is f micrometers, so the distance between the left end of the pixel unit P and the left end of the next pixel unit P is e + f, and the length of the pixel unit P of 2b columns is 2b x (e + f). The length of the pixel cells P of the 2b columns is not more than 300 microns.

For ease of understanding, fig. 6 illustrates an example where k = 3. I.e. the sub-pixels R are arranged in 1 × 3 in the pixel unit P, i.e. there are 1 row and 3 columns of sub-pixels R in one pixel unit P. The length of the sub-pixel R is c micrometers, and the distance between the sub-pixels R of adjacent rows is d micrometers, so that the distance from the upper end of the pixel unit P to the upper end of the next pixel unit P is c + d, and thus the width of the pixel unit P of 2a row is 2a × (c + d). The width of the 2a rows of pixel cells P is no greater than 300 microns.
With reference to fig. 6, the sub-pixels R are arranged in the pixel unit P at 1 × k, the width of the sub-pixel R is e micrometers, the distance between the sub-pixels R in adjacent columns is f micrometers, and b, k, e, and f satisfy the following relations: 2b × k × (e + f) ≦ 300. For ease of understanding, fig. 6 illustrates an example where k = 3. I.e. the sub-pixels R are arranged in 1 × 3 in the pixel unit P, i.e. there are 1 row and 3 columns of sub-pixels R in one pixel unit P. The width e micron of the sub-pixel R, and the distance between the sub-pixels R of the adjacent columns is f micron, so the distance from the left end of the pixel unit P to the left end of the next pixel unit P is 3 × (e + f), and thus the width of the pixel unit P of 2b columns is 2b × 3 × (e + f). The length of the pixel cells P of the 2b columns is not more than 300 microns.
