In some embodiments, the pixel array structure has an RGBG-diamond array scheme, as shown in FIGS. 2A and 2B. Alternatively, sub-pixels among a plurality of sub-pixels in each row of the pixel array structure are arranged in an RGBG arrangement manner. For example, each of the plurality of virtual pixels is a sub-pixel selected from a respective one of a plurality of green sub-pixels and a respective one of a plurality of red sub-pixels and a respective one of the blue sub-pixels. Contains one selected sub-pixel. For example, one of two adjacent pixels has red and green subpixels and the other of the two adjacent pixels has blue and green subpixels.

In some embodiments, the pixel array structure displays a substantially white horizontal line, as shown in FIG. 2A. The virtual pixel 21 located at the i-th column, j-th row has a red sub-pixel R located at the i-th column, j-th row, and a green sub-pixel G located at the i-th column, j-th row. The virtual pixel 22 located at the (i+1)-th column, j-th row has a blue sub-pixel B located at the (i+1)-th column, j-th row, and a green sub-pixel G located at the (i+1)-th column, j-th row.

If the pixel array structure displays a substantially white horizontal line in the jth row, all sub-pixels located in the jth row should emit light. For example, red sub-pixel R located at i-th column j-th row, green sub-pixel G located at i-th column j-th row, blue sub-pixel B located at (i+1)-th column j-th row, (i+1)th Since the green sub-pixels G located in the j-th column and row emit light and the luminance of these sub-pixels is 100% (eg, the gray level of these sub-pixels is 225), a substantially white color is emitted in the j-th row. Show horizontal lines. No signal is sent to the sub-pixels shown as blank sub-pixels in FIG. 2A, eg, the blank sub-pixels shown in FIG. 2A do not emit light. A blank sub-pixel is a sub-pixel that is not filled with a pattern in the figure.

In some embodiments, the pixel array structure displays substantially white vertical lines, as shown in FIG. 2B. The virtual pixel 21 located at the i-th column, j-th row includes the red sub-pixel R located at the i-th column, j-th row, and the green sub-pixel G located at the i-th column, j-th row. The virtual pixel 22 located at the (i+1)-th column, j-th row includes the blue sub-pixel B located at the (i+1)-th column, j-th row, and the green sub-pixel G located at the (i+1)-th column, j-th row. The virtual pixel 23 located at the i-th column (j+1) row includes the blue sub-pixel B located at the i-th column, row (j+1) and the green sub-pixel G located at the i-th column, row (j+1). The virtual pixel 24 located at the (i+1)-th column and the (j+1) -th row is a red sub-pixel located at the (i+1)-th column and the (j+1)-th row. It contains pixel G.

If the pixel array structure displays a substantially white vertical line in the i-th column, all the sub-pixels located in the i-th column emit light, and all the red sub-pixels located in the (i+1)-th column emit light. All blue sub-pixels located in column i+1) should emit light. For example, the red sub-pixel R located at the i-th column and the j-th row, the green sub-pixel G located at the i-th column and the j-th row, the blue sub-pixel B located at the (i+1)-th column and the j-th row, the i-th column and the j-th row. The blue sub-pixel B located in the (j+1) row, the green sub-pixel G located in the i-th column, row (j+1), and the red sub-pixel R located in the (i+1)-th column, row (j+1) all emit light. No signal is sent to the blank sub-pixels shown in FIG. 2B, eg, the blank sub-pixels shown in FIG. 2A do not emit light. The luminance of the red sub-pixel and the blue sub-pixel located in the i-th column is 50% (for example, the gradation of these sub-pixels is 128), and the luminance of the green sub-pixel located in the i-th column is 100% (for example, these 225), and the brightness of the red and blue sub-pixels located in the (i+1)-th column is 50%, so that the i-th column substantially displays a white vertical line.

In some embodiments, the center of luminance of the virtual pixel is located between the green subpixel and the red subpixel adjacent to the green subpixel in the virtual pixel, and the center of luminance of the virtual pixel and the green subpixel are located between the green subpixel and the green subpixel. The distance between is less than between the luminance center of the virtual pixel and the red sub-pixel.

Optionally, as shown in FIGS. 2A and 2B, in a respective one of a plurality of virtual pixels and each of a plurality of green sub-pixels in a respective one of said plurality of virtual pixels and said plurality of A white circle represents the luminance center of the respective one of the plurality of virtual pixels, between each of the plurality of red sub-pixels adjacent to each of the green sub-pixels of .

For example, the luminance center of the virtual pixel 21 at the i-th column, j-th row is positioned between the red sub-pixel R at the i-th column, j-th row and the green sub-pixel R at the i-th column, j-th row. The luminance center of the virtual pixel 22 at the (i+1)th column, the jth row is located between the green subpixel at the (i+1)th row, the jth row and the red subpixel at the (i+2)th column, the jth row.

In some embodiments, when the pixel array structure displays a substantially white horizontal line on the j-th row, as shown in FIG. 2A, the luminance center of the virtual pixel on the j-th row is substantially located on the same parallel straight line.

Optionally, as shown in FIGS. 2A and 2B, the centers of the red sub-pixels and the centers of the blue sub-pixels in the same row are located on the same R&B straight line substantially parallel to the row direction. The centers of green sub-pixels in the same row are positioned on the same G straight line substantially parallel to the row direction, but the same R&B straight line does not overlap the same G straight line.

Alternatively, as shown in FIG. 2A, when using the sub-pixel rendering algorithm in equations (1.1) and (1.4) above, the j-th row forms a substantially white horizontal line. Thus, the green sub-pixel array that emits light in the j-th row is located on the side closer to the (j+1)-th row of the j-th virtual pixel. Therefore, when a substantially white horizontal line is displayed in the j-th row, The j-th row closer to the (j+1)-th row has a substantially greenish white color, and the j-th row closer to the (j-1)-th row has a substantially more purplish white color. have

Alternatively, as shown in FIG. 2B, when the pixel array structure displays a substantially white vertical line in the i-th column, the luminance center of the virtual pixel located in the i-th column is substantially not on the same straight line parallel to

In some embodiments, as shown in FIGS. 2A and 2B, along the row direction, the orthographic projection in a plane perpendicular to the column direction of two green subpixels is the column direction projection of two adjacent red subpixels. lies between the orthographic projections in the plane perpendicular to . Optionally, between any two adjacent red sub-pixels there are no red sub-pixels, but between any two adjacent red sub-pixels there are sub-pixels of other colors other than red. There may be, for example, one blue subpixel between any two adjacent red subpixels.

For example, the red sub-pixel R at the i-th column, j-th row is located on the side away from the (i+1)-th column, row (j+1)-th row of the green sub-pixel G at the i-th column, j-th row. The red subpixel R at the (i+2)th column, jth row is located on the side away from the ith column, row (j+1)th of the green subpixel G at the (i+1)th row, jth row. Therefore, the luminance center of the virtual pixel 22 located at the (i+1)-th column, j-th row is close to the (i+2)-th column, but the luminance center of the virtual pixel 21 located at the i-th column, j-th row is located at the ( i +1)-th row. ) columns, the luminance centers are not evenly distributed, further causing graininess in the image displayed by these sub-pixels.
