Wherein each pixel is composed of three primary colors of red (R), blue (B) and green (G), and each color on each pixel can be a sub-pixel (each dot in fig. 1B). The OLED display screen comprises two types of pixel structures, and each type of pixel structure has corresponding sub-pixel arrangement characteristics. According to the scheme, a plane coordinate system can be established by taking the upper left vertex of the OLED display screen as an origin, the row direction of the screen is an x axis, the column direction of the screen is a y axis, the row sequence number and the column sequence number of each pixel in the screen are respectively taken as the pixel abscissa and the pixel ordinate of each pixel in the screen, and the pixel structure type of each pixel is determined according to the characteristics of the pixel abscissa and the pixel ordinate of each pixel. For example, if the sum of the row number and the column number is an even number, the sub-pixel arrangement characteristic corresponding to the pixel structure type of the pixel is as shown in fig. 1 c. If the sum of the row number and the column number is an odd number, the arrangement characteristics of the sub-pixels corresponding to the pixel structure type of the pixel are as shown in FIG. 1 d.

The number of the groups of the arrangement drawings and the number of the views of each group of the arrangement drawings can be set according to the actual requirement of the display screen. The relative position information of the lenticular with respect to the screen may be the offset angle between the direction of the principal axis of the lenticular elements and the direction of the columns of pixels of the display screen. The offset of the sub-pixel relative to the screen may be the specific location of the sub-pixel on the screen. The offset of each sub-pixel in the screen relative to the screen is unique. According to the scheme, the view number matched with each sub-pixel and the offset of each sub-pixel relative to the screen can be respectively determined according to each sub-coordinate, the width of the cylindrical lens and the relative position information of the cylindrical lens relative to the screen.

For example, as shown in FIG. 1b, a pixel is located in the second row and the third column of the display screen. Because the pixel structure type of the display screen is periodically arranged at intervals, the scheme can determine the pixel structure type of the pixel based on the periodic position of the pixel in the display screen. For example, the present scheme may determine the type of pixel structure of the pixels located in the second row and the third column of the display screen as shown in fig. 1 d.

Specifically, assuming that the screen resolution of the OLED display screen is m × n, the screen is considered to be divided into m rows and n columns, and the position of each pixel in the screen can be marked as (r, s). Wherein r is more than or equal to 1 and less than or equal to m, s is more than or equal to 1 and less than or equal to n, r is the row period position of the pixel in the display screen, and s is the column period position of the pixel in the display screen. Since the row period position and the column period position of the pixel in the display screen are associated with the pixel structure type of the pixel, the present scheme can determine the pixel structure type of the pixel based on the row period position and the column period position of the pixel in the display screen.
Therefore, the pixel structure type of the pixel is determined based on the row period position and the column period position of the pixel in the display screen, the pixel structure type distribution characteristic of the OLED display screen can be fully utilized, the pixel structure type can be accurately determined, and reliable data support is provided for the subsequent steps.

For example, as shown in fig. 1b and fig. 1d, if the present scheme determines that the sum of the row number and the column number of the pixel in the display screen is an odd number, the present scheme may determine that the pixel structure type of the pixel is as follows: the sub-pixel B is located at the upper right vertex of the square pixel (p2), the sub-pixel R is located at the lower right vertex of the square pixel (p0), and the sub-pixel G is located at the center point of the square pixel (p 1).
Thus, the pixel structure type of the pixel is determined by whether the sum of the row number and the column number where the pixel is located in the display screen is an odd number. The pixel structure type distribution characteristics of the OLED display screen can be fully utilized, the pixel structure type can be accurately determined, and reliable data support is provided for subsequent steps.

For example, as shown in fig. 1b and fig. 1c, if the present scheme determines that the sum of the row number and the column number of the pixel in the display screen is an even number, the present scheme may determine that the pixel structure type of the pixel is as follows: the sub-pixel R is located at the upper right vertex of the square pixel (p0), the sub-pixel B is located at the lower right vertex of the square pixel (p2), and the sub-pixel G is still located at the center point of the square pixel (p 1).
Thus, the pixel structure type of the pixel is determined by whether the sum of the row number and the column number where the pixel is located in the display screen is an even number. The pixel structure type distribution characteristics of the OLED display screen can be fully utilized, the pixel structure type can be accurately determined, and reliable data support is provided for subsequent steps.

In this scheme, the coordinate position of the pixel in the corresponding square pixel may be specified in advance, for example, the coordinate point of the pixel may be located at the top left vertex of the corresponding square pixel, or the coordinate point of the pixel may also be located at the center point of the corresponding square pixel. The coordinate point of the pixel may also be located at other positions of the square pixel corresponding thereto. The scheme can also determine the sub-pixel arrangement characteristics of the pixels according to the pixel structure types, determine the specific coordinates of the pixels according to the row serial numbers and the column serial numbers of the pixels in the display screen, and further determine the pixel areas of the pixels according to the specific coordinates of the pixels. And determining the sub-coordinate of each sub-pixel in the pixel according to the pixel area, the sub-pixel arrangement characteristics of the pixel and the coordinate position of the pixel in the pixel area.

In a possible embodiment, optionally, displaying each of the sub-pixels according to the view number and the offset includes: determining a target view matched with the sub-pixels according to the view number and the number of views matched with the lenticules; determining a target sub-pixel according to the target view and the offset; and correspondingly displaying the sub-pixels by adopting the value of the target sub-pixel.
The number of views may be 8, 28, and the number of views may be set according to actual needs. According to the scheme, the specific view in the row diagram corresponding to the cylindrical lens, namely the target view, can be determined according to the view number and the number of the views matched with the cylindrical lens. For example, if the view number is 5 and the number of views in a group of row maps corresponding to each lenticular is 28, the target view is the 5 th view. According to the scheme, the pixels and the pixel values corresponding to the sub-pixels in all the rows of the screen are determined according to the offset of the sub-pixels relative to the screen and the target view corresponding to the sub-pixels, and the pixel values are assigned to the sub-pixels so that the sub-pixels can display.
Thus, a target view matched with the sub-pixel is determined according to the view number and the view number matched with the cylindrical lens; determining a target sub-pixel according to the target view and the offset; and correspondingly displaying the sub-pixels by adopting the value of the target sub-pixel. The normal naked eye 3D display interface and display effect can be displayed on the OLED display screen, and the advantages of the OLED display screen can be fully exerted.

Fig. 3a is a flowchart of a naked eye 3D display method based on an OLED display screen according to an embodiment of the present invention, and the embodiment is optimized based on the foregoing embodiment. As shown in fig. 3a, the naked-eye 3D display method based on the OLED display screen in the embodiment of the present invention may include:

And S320, respectively determining view numbers matched with the sub-pixels according to the sub-coordinates, the screen center point, the width of the cylindrical lens and the offset angle of the main axis direction of the cylindrical lens relative to the column direction of the screen pixels.
Because the grating cylindrical lens is obliquely arranged on the display screen, the grating cylindrical lens forms a certain included angle relative to the display screen, namely the deviation angle of the main shaft direction of the cylindrical lens relative to the pixel column direction of the screen. The offset angle can be 20 degrees, and the offset angle can also be 30 degrees, and the offset angle can be set according to actual needs. The screen center point is the center position of the display screen.
In this embodiment, optionally, the view number matching with the sub-pixel is determined based on the following formula:
no＝([(x1-x0)+(y0-y1)×tan(a)]/pitch)×number％number；
where no denotes a view number matched with a sub-pixel, x1 denotes an abscissa of the sub-coordinate, y1 denotes an ordinate of the sub-coordinate, x0 denotes an abscissa of the screen center point pixel, y0 denotes an ordinate of the screen center point pixel, pitch denotes a lenticular width, a denotes a shift angle of a lenticular major axis direction with respect to a screen pixel column direction, and number denotes the number of views matched with a lenticular.
Illustratively, as shown in fig. 3b, assuming that the view number of the row map matched with the lenticular lens is 28, the coordinate of the pixel p in the display screen is (x, y), the pixel number coordinate of the pixel O at the center point of the screen is (960, 540), and the lenticular lens width is the number of pixels covered in the width direction by one lenticular lens period determined according to the physical width and the pixel pitch of the lenticular lens. Then, in conjunction with fig. 1b, 1c and 1d, the view numbers matching the sub-coordinates of the sub-pixels under the arrangement characteristics of the different sub-pixels can be determined respectively. As shown in fig. 1c and fig. 3c, when the abscissa of the pixel plus the ordinate of the pixel is an even number, the sub-coordinates of the three sub-pixels R, G, and B are: p0(p.x +1, p.y), p1(p.x +1/2, p.y +1/2), p2(p.x +1, p.y + 1); the view numbers matched with the three sub-pixels of R, G and B are respectively as follows:
p0_no＝([PA+AB]/pitch)×28％28＝([(x+1-960)+(540-y)×tan(a)]/pitch)×28％28；
p1_no＝([PA+AB]/pitch)×28％28＝([(x+1/2-960)+(540-(y+1/2))×tan(a)]/pitch)×28％28；
p2_no＝([PA+AB]/pitch)×28％28＝([(x+1-960)+(540-(y+1))×tan(a)]/pitch)×28％28。
as shown in fig. 1d, when the abscissa of the pixel plus the ordinate of the pixel is an odd number, the sub-coordinates of the three sub-pixels R, G, and B are: p0(p.x +1, p.y +1), p1(p.x +1/2, p.y +1/2), p2(p.x +1, p.y); the view numbers respectively matched with the three sub-pixels of R, G and B are as follows:
p0_no＝([PA+AB]/pitch)×28％28＝([(x+1-960)+(540-(y+1))×tan(a)]/pitch)×28％28；
p1_no＝([PA+AB]/pitch)×28％28＝([(x+1/2-960)+(540-(y+1/2))×tan(a)]/pitch)×28％28；
p2_no＝([PA+AB]/pitch)×28％28＝([(x+1-960)+(540-y))×tan(a)]/pitch)×28％28。
therefore, the view matched with the sub-pixels can be determined by determining the view number matched with the sub-pixels, and an accurate pixel source can be provided for naked eye 3D display of the OLED display screen.
And S330, respectively determining the offset of each sub-pixel relative to the screen according to each sub-coordinate and the screen parameter.
Wherein the screen parameters include: screen height and screen length.

The unit of the screen length and the screen height may be a length unit or a pixel unit. After determining the sub-coordinates of each sub-pixel under the arrangement characteristics of different sub-pixels, the scheme can determine the offset of the sub-pixels relative to the screen, namely the specific positions of the sub-pixels on the OLED display screen according to the sub-coordinates of the sub-pixels, the screen height and the screen length of the OLED display screen.
In this embodiment, optionally, the determining process of the offset of the sub-pixel with respect to the screen includes: determining the lateral offset of the sub-pixel according to the abscissa of the sub-coordinate and the length of the screen; determining the longitudinal offset of the sub-pixel according to the ordinate of the sub-coordinate and the screen height; and determining the offset of the sub-pixel relative to the screen according to the transverse offset and the longitudinal offset.
Specifically, if the screen height of the OLED display screen is 1080, the screen length is 1920, and the sub-coordinate of the sub-pixel is (192, 108), the lateral offset of the abscissa of the sub-coordinate with respect to the screen length 1920 is 192/1920 ═ 0.1, and the longitudinal offset of the ordinate of the sub-coordinate with respect to the screen height 1080 is 0.1, it can be determined from the determined lateral offset and longitudinal offset that the offset of the sub-pixel of the sub-coordinate (192, 108) with respect to the screen is 10% of the screen length and 10% of the screen height.
Thereby, the lateral offset of the sub-pixel is determined according to the abscissa in the sub-coordinate and the screen length; determining the longitudinal offset of the sub-pixels according to the vertical coordinate in the sub-coordinates and the height of the screen; and determining the offset of the sub-pixel relative to the screen according to the transverse offset and the longitudinal offset.

And S340, correspondingly displaying each sub-pixel according to the view number and the offset.
The technical scheme provided by the embodiment of the invention comprises the steps of determining the pixel structure type of a pixel, determining the sub-coordinate of each sub-pixel in the pixel based on the pixel structure type, respectively determining the view number matched with each sub-pixel according to each sub-coordinate, the screen center point, the width of a cylindrical lens and the offset angle of the main axis direction of the cylindrical lens relative to the column direction of the screen pixel, respectively determining the offset of each sub-pixel relative to the screen according to each sub-coordinate and the screen parameter, and correspondingly displaying each sub-pixel according to the view number and the offset. By executing the scheme, normal naked eye 3D display interface and display effect can be displayed on the OLED display screen, and the advantages of the OLED display screen can be fully played.
In order to express the technical scheme of the present invention more clearly, the technical scheme provided by the embodiment of the present invention may include the following steps:
step 1, obtaining parameters of the lenticular lens, the number N of views matched with the lenticular lens and relative position information of the lenticular lens element relative to the pixels of the display screen.
Therein, the number of views N may be 28. The relative position of the lenticular elements with respect to the display screen pixels may be: the included angle a between the main axis direction of the cylindrical lens element and the pixel column direction of the display screen.
And 2, determining the sub-coordinates of the sub-pixels in each pixel based on the arrangement characteristics of the pixels of the OLED screen, and determining the view numbers corresponding to the sub-pixels based on a preset algorithm.
When the pixel arrangement characteristics of the OLED screen satisfy various characteristics, for example, the pixel abscissa plus the pixel ordinate are odd and even, the spatial distribution pattern corresponds to R, G, B three-color sub-pixels. The sub-coordinates of the R, G, B three-color sub-pixel under each layout feature can be determined separately for that layout feature.
And 3, for each sub-pixel, extracting pixel data at a corresponding position from the view data of the view number corresponding to the sub-pixel for display.
Illustratively, as shown in fig. 3b, the number N of views is 28 (the number N can be set according to actual needs), and there are two types of pixel structures of the OLED display panel, which correspond to the case where the abscissa of the pixel plus the ordinate of the pixel are odd and even, respectively. There may be more pixel structure types, such as 3, 6 … …
Fig. 1b illustrates a 6 column by 4 row 24 pixel OLED display panel. In any two adjacent pixels, R, G, B three-color sub-pixels are not uniformly distributed in space. There are two cases: the pixel abscissa plus the pixel ordinate is even (as shown in fig. 1 c) and the pixel abscissa plus the pixel ordinate is odd (as shown in fig. 1 d). There are only 24+15+ 15-54 physical sub-pixels in the screen. The red and blue colors between adjacent rows are common.
As shown in fig. 3c, it is assumed that the pixel coordinate p (x, y) is located at the position of the upper left vertex of the square pixel corresponding to the pixel (note: the assumption that the pixel coordinate is located at the position of a square pixel of 1 × 1 size, theoretically any position is possible). When the abscissa of the pixel plus the ordinate of the pixel is even, the structure is as shown in fig. 1 c: r, G, B obtain the sub-coordinates of the three sub-pixels as: p0(p.x +1, p.y), p1(p.x +1/2, p.y +1/2), p2(p.x +1, p.y + 1); when the abscissa of the pixel plus the ordinate of the pixel is odd, the structure is as shown in FIG. 1 d: r, G, B obtain the sub-coordinates of the three sub-pixels as: p0(p.x +1, p.y +1), p1(p.x +1/2, p.y +1/2) and p2(p.x +1, p.y) were obtained. The view number, which is located at 28 equally divided lenticular strips, is calculated when the abscissa of the pixel plus the ordinate of the pixel is even:
p0_no＝([PA+AB]/pitch)×28％28＝([(x+1-960)+(540-y)×tan(a)]/pitch)×28％28；
p1_no＝([PA+AB]/pitch)×28％28＝([(x+1/2-960)+(540-(y+1/2))×tan(a)]/pitch)×28％28；
p2_no＝([PA+AB]/pitch)×28％28＝([(x+1-960)+(540-(y+1))×tan(a)]/pitch)×28％28。
when the abscissa of a pixel plus the ordinate of the pixel is odd:
p0_no＝([PA+AB]/pitch)×28％28＝([(x+1-960)+(540-(y+1))×tan(a)]/pitch)×28％28；
p1_no＝([PA+AB]/pitch)×28％28＝([(x+1/2-960)+(540-(y+1/2))×tan(a)]/pitch)×28％28；
p2_no＝([PA+AB]/pitch)×28％28＝([(x+1-960)+(540-y))×tan(a)]/pitch)×28％28。
it should be noted that the percentage is a remainder operation, the lenticular width pitch is the number of pixels covered in the width direction of one lenticular period determined according to the ratio of the physical width of the lenticular to the pixel pitch, the pixel coordinate O (960, 540) of the screen center point is an example of the arrangement reference point, in practice, other position points at the boundary of the arrangement period may also be selected as the arrangement reference point, and the preferred mode in the present scheme is to select the screen center point as the arrangement reference point.
