The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, 2 and 3, an exemplary embodiment of a pixel structure according to the present invention includes: a first subpixel 10, a second subpixel 20, and a third subpixel 30, the first subpixel 10 being arranged in a first subpixel row in a row direction, the second subpixel 20 and the third subpixel 30 being alternately arranged in the row direction, the first subpixel row being alternately arranged with a row formed by the second subpixel and the third subpixel;
the first sub-pixels 10 are arranged in a first sub-pixel column in a column direction, the second sub-pixels 20 and the third sub-pixels 30 are alternately arranged in the column direction, and columns formed by the second sub-pixels 20 and the third sub-pixels 30 and the first sub-pixel columns are alternately arranged in a one-to-two number; the geometric center of the second sub-pixel 20 or the third sub-pixel 30 is located on the middle line of the connecting line of the centers of any two adjacent first sub-pixels;
wherein the second sub-pixels 20 and the third sub-pixels 30 are alternately arranged at intervals in a row direction; specifically, the second subpixel 20 and the third subpixel 30 form a column adjacent to two of the first subpixel columns.
Wherein the geometric center of the second sub-pixel 20 or the third sub-pixel 30 is at the geometric center of four of the first sub-pixels adjacent thereto; specifically, one second sub-pixel 20 or one third sub-pixel 30 and four first sub-pixels 10 form one theoretical pixel unit 2, in the theoretical pixel unit 2, the four first sub-pixels 10 are distributed at four corners, and the intersection point of the diagonal lines of the four first sub-pixels is the geometric center of the second sub-pixel 20 or the third sub-pixel 30.
Four of said first sub-pixels 10 and one of said second sub-pixels 20 and one of said third sub-pixels 30 constitute one minimum sub-pixel cycle period unit 1, and in the row direction, the positions of the second sub-pixels 20 and the third sub-pixels 30 are interchanged in odd and even minimum sub-pixel cycle periods.
The four first sub-pixels 10, one second sub-pixel 20 and one third sub-pixel 30 form a minimum sub-pixel cycle period unit 1, and the positions of the second sub-pixel 20 and the third sub-pixel 30 in the odd-even minimum sub-pixel cycle period in the row direction are interchanged, which means that:
in the row direction, in an odd-numbered minimum sub-pixel cycle period, a first row of the minimum sub-pixel cycle period unit 1 is four of the first sub-pixels, and a second row is sequentially arranged as the second sub-pixels and the third sub-pixels; in the even-numbered minimum sub-pixel cycle period, the first row of the minimum sub-pixel cycle period unit 1 is four first sub-pixels, and the second row is sequentially arranged as the third sub-pixel and the second sub-pixel.
Or, a minimum sub-pixel cycle period unit 1 is composed of four first sub-pixels 10, one second sub-pixel 20 and one third sub-pixel 30, and the positions of the second sub-pixel 20 and the third sub-pixel 30 are interchanged in odd and even minimum sub-pixel cycle periods in the column direction.
The four first sub-pixels 10, one second sub-pixel 20 and one third sub-pixel 30 form a minimum sub-pixel cycle period unit 1, and in the column direction, in the odd-even minimum sub-pixel cycle period, the positions of the second sub-pixel 20 and the third sub-pixel 30 are interchanged, which means that:
in the column direction, in the odd-numbered minimum sub-pixel cycle period, the first column of the minimum sub-pixel cycle period unit 1 is two of the first sub-pixels, the second column is sequentially arranged as the second sub-pixel and the third sub-pixel, and the third column is two of the first sub-pixels; in the even-numbered minimum sub-pixel cycle period, the first column of the minimum sub-pixel cycle period unit 1 is two first sub-pixels, and the second column is sequentially arranged as the third sub-pixel and the second sub-pixel, two first sub-pixels.

The display color of the first sub-pixel 10 is green, the display color of the second sub-pixel 20 is red or blue, and the display color of the third sub-pixel 30 is blue or red.
The ratio of the first sub-pixel 10, the second sub-pixel 20 and the third sub-pixel 30 in the total number is 4: 1: 1.
it should be noted that, in practice, the first sub-pixel 10 retains the full resolution of the original data, while the second sub-pixel 20 and the third sub-pixel 30 retain only 1/4 of the resolution of the original data, where the row direction and the column direction are each 1/2 of the original data.
In practical applications, especially in application scenarios with ultra-high PPI, the human eye distinguishes details mainly from brightness, and among red, green and blue sub-pixels, the brightness of green is the highest, and the resolution of green is preserved to effectively preserve details of the image, so in the pixel arrangement structure of this embodiment, the first sub-pixel 10 corresponds to a green pixel and green data in the input data one-to-one, and the second sub-pixel 20 and the third sub-pixel 30 are shared by a plurality of adjacent data pixels.
In the pixel arrangement structure of the embodiment of the present invention, the sum of the numbers of the first sub-pixel, the second sub-pixel and the third sub-pixel is 1/2 of the theoretical pixel unit 2, which can actually greatly reduce the data amount sent by display, reduce the number of data lines, make the aperture ratio of the panel higher, and reduce the requirement of the driving capability and the power consumption.
Referring to fig. 1 and 2, a specific embodiment of the present invention provides a pixel structure for an OLED, including: a first sub-pixel 10, a second sub-pixel 20, and a third sub-pixel 30.
The geometric centers of the first sub-pixels 10 of the successive rows and the successive columns are arranged in an oblique line in an oblique direction different from the row direction or the column direction; the geometric centers of the second sub-pixel 20 or the third sub-pixel 30 of the consecutive rows and the consecutive columns are arranged in an oblique line in an oblique direction different from the row direction or the column direction;
the geometric centers of the second sub-pixels 20 of the consecutive rows and the consecutive columns are arranged in an oblique line in an oblique direction different from the row direction or the column direction; the geometric centers of the third sub-pixels 30 of the consecutive rows and the consecutive columns are arranged in an oblique line in an oblique direction different from the row direction or the column direction; oblique lines in which the geometric centers of the second sub-pixels 20 of the consecutive rows and the consecutive columns are arranged in oblique directions different from the row direction or the column direction and oblique lines in which the geometric centers of the third sub-pixels 30 of the consecutive rows and the consecutive columns are arranged in oblique directions different from the row direction or the column direction are alternately arranged in a direction perpendicular to the oblique lines;
wherein, the oblique direction of the oblique line formed by the first sub-pixel is the direction of clockwise 45 degrees or anticlockwise 45 degrees in the row direction or the column direction; the oblique direction of the oblique line formed by the second sub-pixel or the third sub-pixel is a direction which is rotated by 26.57 degrees clockwise or 26.57 degrees counterclockwise in the row direction or the column direction.
Wherein, 26.57 degrees is an approximate calculation result of arctan (0.5).
Geometric centers of the first sub-pixels 10 of the consecutive rows and the consecutive columns are symmetrically distributed on both sides of a diagonal line formed by the geometric centers of the second sub-pixels 20 or the third sub-pixels 30 of the consecutive rows and the consecutive columns in an oblique direction different from the row direction or the column direction.
It is understood that, combining the shape of the first sub-pixel 10 and the positions of the second sub-pixel 20 and the third sub-pixel 30, the first sub-pixel 10 can slightly shift its geometric center to the empty column between the second sub-pixel 20 and the third sub-pixel 30 to make the distance between the sub-pixels of different colors larger, so that the first sub-pixel 10 may be actually distributed on both sides of the theoretical oblique line.
The first sub-pixel 10 is an isosceles triangle rotated by 90 degrees; the second sub-pixel 20 and the third sub-pixel 30 are both diamond-shaped.
The corner edges of the first sub-pixel 10 are parallel to the second sub-pixel 20 and the third sub-pixel 30, and two first sub-pixels in adjacent columns are mirror images of each other.
It is understood that, in order to ensure the boundary distance between the first sub-pixel 10 and the second sub-pixel 20 and the third sub-pixel 30, the corner edges of the first sub-pixel 10 must be parallel for the second sub-pixel 20 and the third sub-pixel 30, so that the two first sub-pixels in adjacent columns are mirror images of each other.
The area of the second sub-pixel 20 is equal to the area of the third sub-pixel 30, and the area of the first sub-pixel 10 is 1/4 of the area of the second sub-pixel 20.
It will be appreciated that the blue pixel, i.e., the third sub-pixel 30, may be slightly larger than the red pixel, i.e., the second sub-pixel 20, taking into account the differences in the luminous efficiency and the aging rate of the materials.
The area of the second sub-pixel 20 displaying the color red is smaller than the area of the third sub-pixel 30 displaying the color blue, or the area of the second sub-pixel 20 displaying the color blue is smaller than the area of the third sub-pixel 30 displaying the color red.

the second sub-pixel 20 and the third sub-pixel 30 are identical in size and equal to four times the first sub-pixel 10. The widths of the second and third sub-pixels 20 and 30 are equal to twice the width of the first sub-pixel 10, and the heights of the second and third sub-pixels 20 and 30 are equal to twice the height of the first sub-pixel 10.
The aspect ratio of the second sub-pixel 20 and the third sub-pixel 30 is 3: 1.
the first sub-pixel 10 is a green sub-pixel, the second sub-pixel 20 is a red sub-pixel, and the third sub-pixel 30 is a blue sub-pixel.
The present invention provides an exemplary embodiment, a rendering method of the above-mentioned pixel structure, including the steps of:
s1, obtaining theoretical luminance values of colors corresponding to the display colors of the first sub-pixel 10, the second sub-pixel 20 and the third sub-pixel 30 in each pixel unit from the pixel display information data;
s2, calculating actual luminance values of the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30; wherein, the actual brightness value of the first sub-pixel 10 is set as the theoretical brightness value of the color corresponding to the display color thereof; the actual luminance value of the second sub-pixel 20 or the third sub-pixel 30 is a weighted sum of theoretical luminance values of the four corresponding positions of the first sub-pixel 10 in the theoretical pixel unit 2; the theoretical pixel unit 2 is composed of one second sub-pixel 20 or one third sub-pixel 30 and four first sub-pixels 10;
the weighting coefficient is obtained by calculation of Euclidean distance;
s3, inputting actual brightness values to the first sub-pixel 10, the second sub-pixel 20 and the third sub-pixel 30 to realize image display.
The weighting coefficient is one fourth.
It will be appreciated that the weighting factor is 1/4, since the second sub-pixel 20 is at the geometric center of the four first sub-pixels 10, i.e. at equal distances from the four first sub-pixels.
The present invention provides an exemplary embodiment, a display device, comprising the above-described pixel structure; the display device is an organic light emitting diode display device or a liquid crystal display device.
According to the invention, the aperture opening ratio and the pixel resolution of the sub-pixels are improved by optimizing the arrangement mode of the sub-pixels, and the aperture opening distances of the sub-pixels with different colors are increased by optimizing the number proportion of the sub-pixels, so that the brightness of a pixel structure is improved, and the display effect of the display device is enhanced; meanwhile, by using the rendering method aiming at the pixel structure, the physical resolution of red and blue colors is reduced while the brightness details of green are kept, the display effect of an image is ensured, and the power consumption of a display device is reduced.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
