For example, if the sum of the row number and the column number is an even number, the sub-pixel arrangement characteristics corresponding to the pixel structure type of the pixel are as shown in fig. 1 c. If the sum of the row number and the column number is odd, the sub-pixel arrangement characteristics corresponding to the pixel structure type of the pixel are shown in fig. 1 d. The scheme can further determine the sub-coordinates of each sub-pixel in the pixel according to the pixel structure type of the pixel. Wherein the sub-coordinates also include an abscissa and an ordinate.

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. Because 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 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.

The coordinate point of the pixel may be preset to be located at a coordinate position in the square pixel corresponding to the coordinate point, for example, the coordinate point of the pixel may be located at an upper left vertex of the square pixel corresponding to the coordinate point of the pixel, or the coordinate point of the pixel may be located at a center point of the square pixel corresponding to the coordinate point of the pixel. The coordinate point of the pixel may also be located at other positions of the square pixel corresponding thereto. According to the scheme, the sub-pixel arrangement characteristics of the pixels can be determined according to the pixel structure type, the specific coordinates of the pixels are determined according to the row serial numbers and the column serial numbers of the pixels in the display screen, and then the pixel areas of the pixels are determined according to the specific coordinates of the pixels.

In a possible implementation manner, optionally, displaying each sub-pixel correspondingly according to the view number and the offset includes: determining a target view matched with the sub-pixel according to the view number and the number of views matched with the column lens; determining a target sub-pixel according to the target view and the offset; and displaying the sub-pixels correspondingly by adopting the values of the target sub-pixels.
The number of views can be 8 or 28, and can be set according to actual needs. According to the scheme, the specific view in the row diagram corresponding to the column mirror, namely the target view, can be determined according to the view number and the number of views matched with the column mirror. For example, if the view number is 5, and the number of views of the row of the map corresponding to each of the cylindrical lenses is 28, the target view is the 5 th view. According to the scheme, the pixel and the pixel value corresponding to the sub-pixel in all rows of the screen can be determined according to the offset of the sub-pixel relative to the screen and the target view corresponding to the sub-pixel, and the pixel value is assigned to the sub-pixel so that the sub-pixel can be displayed.

And further, specific pixels matched with the sub-pixels in the row diagram can be determined according to the row diagram rule of the display screen and the offset of the screen, and a normal naked eye 3D display interface and display effect can be displayed on the OLED display screen.
And S340, displaying the sub-pixels correspondingly according to the view numbers and the offset.
According to the technical scheme provided by the embodiment of the invention, the pixel structure type of the pixel is determined, the sub-coordinates of each sub-pixel in the pixel are determined based on the pixel structure type, the view numbers matched with the sub-pixels are respectively determined according to the sub-coordinates, the center point of the screen, the width of the column mirror and the offset angle of the column mirror main axis direction relative to the column direction of the screen pixel, the offset of the sub-pixels relative to the screen is respectively determined according to the sub-coordinates and the screen parameters, and the sub-pixels are correspondingly displayed according to the view numbers and the offset. By executing the scheme, 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.
In order to clearly describe the technical scheme of the invention, the technical scheme provided by the embodiment of the invention can comprise the following steps:
Step 1, obtaining a lenticular parameter, the number of views N matched with the lenticular lens, and relative position information of the lenticular lens element relative to the display screen pixel.
Wherein the number of views N may be 28. The relative positions of lenticular elements with respect to display screen pixels may be: and an included angle a between the main axis direction of the columnar lens element and the pixel column direction of the display screen.
And 2, determining sub-coordinates of sub-pixels in each pixel based on arrangement characteristics of pixels of the OLED screen, and determining a view number corresponding to each sub-pixel based on a predetermined algorithm.
When the pixel arrangement characteristics of the OLED screen satisfy various characteristics, for example, when the pixel abscissa and the pixel ordinate are odd and even, a R, G, B three-color sub-pixel spatial distribution mode is respectively corresponding. The sub-coordinates of R, G, B three-color sub-pixels under each arrangement feature can be determined separately according to the arrangement feature.
And 3, extracting pixel data at corresponding positions from view data of the view numbers corresponding to each sub-pixel for display.
For example, as shown in fig. 3b, the number N of views is taken as 28 (the number N can be set according to actual needs), and the pixel structure of the OLED display screen has two types, which correspond to the case that the pixel abscissa and the pixel ordinate are respectively odd and even. The pixel structure types can be more various, such as 3 kinds, 6 kinds … … kinds
Fig. 1b illustrates a block of 6 column x 4 row = 24 pixel OLED display screen. In any two adjacent pixels, R, G, B three-color sub-pixels are distributed in a non-uniform space. There are two things in common: the pixel abscissa plus pixel ordinate is even (as shown in fig. 1 c) and the pixel abscissa plus pixel ordinate is odd (as shown in fig. 1 d). There are only 24+15+15=54 physical subpixels in the screen. The red and blue colors between adjacent rows are common.
As shown in fig. 3c, the pixel coordinates p (x, y) are assumed to be located at the position of the upper left vertex of the square pixel corresponding to the pixel (note: the assumption that the pixel coordinates are located at the 1 x 1 size square pixel position can theoretically be at any position). When the abscissa of the pixel plus the ordinate of the pixel is even, the structure is as shown in fig. 1 c: the sub-coordinates of the R, G, B sub-pixels are respectively: 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: the sub-coordinates of the R, G, B sub-pixels are respectively: p0 (p.x +1, p.y+1), p1 (p.x +1/2, p.y+1/2), p2 (p.x +1, p.y) are obtained. The view number of the aliquoting lenticular strip sitting at 28 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 the 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。
note that,% is a remainder operation, the cylinder width pitch is the number of pixels covered in the width direction by one cylinder period determined according to the ratio of the physical width of the cylinder to the pixel pitch, the pixel coordinate O (960, 540) of the center point of the screen is an example of a line-up reference point, and in practice, other position points at the boundary of the line-up period may be selected as line-up reference points, where a preferred manner is to select the center point of the screen as the line-up reference point.
