Description

Display pixel arrangement structure

The present invention relates to a pixel arrangement structure, and more particularly to a pixel arrangement structure of a display.

In order to make the image displayed on the display more realistic, various displays are actively developing toward high resolution and full color. Conventional techniques generally increase the resolution by increasing the number of pixels in the vertical and horizontal directions of the display, and achieve full color by setting a plurality of sub-pixels of different colors in each pixel.

In general, methods of increasing the number of pixels include reducing the area of sub-pixels or reducing the spacing between adjacent sub-pixels. However, reducing the area of the sub-pixels results in a reduction in aperture ratio and affects the display brightness of the display. On the other hand, if the spacing between adjacent sub-pixels is reduced, the spacing between the corresponding display medium patterns will also be reduced together. When the adjacent sub-pixels are of different colors, reducing the spacing between the display medium patterns tends to cause a problem of material color mixing. In addition, the spacing between the display media patterns may have their reduced limits depending on the process used. Taking an Organic Light Emitting Device (OLED) as an example, an organic light emitting display The organic material used for the display medium pattern (for example, the organic light-emitting layer) is deteriorated by the influence of moisture and oxygen in the environment, and must be formed by vapor deposition. In the process of vaporizing an organic material, a mask for defining a size of a display medium has a processing limit, and thus an organic light-emitting display is generally difficult to realize a high-resolution display technology.

The invention provides a pixel arrangement structure of a display, which can improve the resolution of the display, and takes into consideration the resolution and the display quality.

A pixel arrangement structure of a display of the present invention includes a plurality of pixel groups. The pixel groups are arranged along the intersecting first axis and the second axis to form a two-dimensional array, wherein each pixel group includes two first color sub-pixels and two pairs of sub-pixels. The first color sub-pixel is disposed on a central vertical line of the associated pixel group, wherein the first axial direction and the second axial direction are respectively at the same angle as the central vertical line. The two pairs of sub-pixels are arranged along the central horizontal line of the associated pixel group, and the two pairs of sub-pixels are respectively located at two symmetrical positions on opposite sides of the central vertical line. The two pairs of sub-pixels are composed of two second color sub-pixels and two third color sub-pixels.

Based on the above, the pixel arrangement structure of the display of the embodiment of the present invention causes two pairs of sub-pixels in each pixel group to be misaligned with the first color sub-pixels (or called misalignment) to make the sub-pictures At the same time as the arrangement of the elements is dense, the aperture ratio of each sub-pixel is greatly improved. Therefore, the pixel arrangement structure of the display of the embodiment of the present invention can improve the resolution of the display, and take into consideration both the resolution and the display quality.

The above described features and advantages of the invention will be apparent from the following description.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a partial top plan view showing a pixel arrangement structure of a display in accordance with a first embodiment of the present invention. 3 and 4 are partial top views of pixel arrangement structures of two other displays in accordance with a first embodiment of the present invention. Referring first to FIG. 1, the pixel arrangement structure 100 of the display of the present embodiment includes a plurality of pixel groups G. The pixel groups G are arranged along the intersecting first axis D1 and the second axis D2 to form a two-dimensional array.

Each pixel group G includes two first color sub-pixels SP1 and two pairs of pixels. The pixels (including the first pair of sub-pixels SPA and the second pair of sub-pixels SPB). The first pair of subpixels SPA and the second pair of subpixels SPB are respectively composed of two second color subpixels SP2 and two third color subpixels SP3. In this embodiment, the first pair of subpixels SPA is composed of two second color subpixels SP2, and the second pair of subpixels SPB is composed of two third color subpixels SP3. That is, the two sub-pixels of each pair of sub-pixels are substantially the same color, but are not limited thereto. In another embodiment, the first pair of sub-pixels SPA may be combined by a second color sub-pixel SP2 and a third color sub-pixel SP3, and the second pair of sub-pixels SPB may be a second color sub- The pixel SP2 and a third color sub-pixel SP3 are combined, that is, the two sub-pixels of each pair of sub-pixels are different colors.

The first color sub-pixel SP1, the second color sub-pixel SP2, and the third color sub-pixel SP3 may be a green sub-pixel, a red sub-pixel, and a blue sub-pixel, respectively. However, the colors displayed by the first color subpixel SP1, the second color subpixel SP2, and the third color subpixel SP3 may be changed according to design requirements, for example, cyan (c), magenta (magenta, M) ), yellow (yellow), or other suitable color, without being limited to the above.

A diamond-shaped boundary is defined between the adjacent pixel groups G along the first axis D1 and the second axis D2, and the first axis D1 and the second axis D2 are substantially parallel to the adjacent diamonds, respectively. Both sides. In other words, the angle (twice the angle θ1) of the first axial direction D1 and the second axial direction D2 is greater than 0 degrees and less than about 180 degrees.

Each pixel group G has a central vertical line CVL and a central horizontal line CHL, wherein the first axial direction D1 and the second axial direction D2 are respectively perpendicular to the central vertical line CVL The first axial direction D1 and the second axial direction D2 are substantially the same angle θ2 with the central horizontal line CHL, and the sum of the angle θ1 and the angle θ2 is about 90 degrees. In other embodiments, the angle between the first axial direction D1 and the second axial direction D2 and the central vertical line CVL may be substantially different, and the first axial direction D1 and the second axial direction D2 are respectively separated from the central horizontal line CHL. The sandwiched angle θ2 may be substantially different, but the central vertical line CVL and the central horizontal line CHL may be sandwiched by an angle of about 90 degrees, which is approximately equal to the sum of the angle θ1 and the angle θ2. Specifically, the central vertical line CVL and the central horizontal line CHL are diagonal lines of the above-described diamond shape, respectively. That is, the central vertical line CVL and the central horizontal line CHL are substantially perpendicular to each other, and the central vertical line CVL intersects the central horizontal line CHL at the center O of the associated pixel group G. In the present embodiment, the central vertical line CVL is, for example, a relatively short diagonal line in the above-described diamond shape, and the central horizontal line CHL is, for example, a relatively long diagonal line among the above-described diamond shapes. Therefore, the angle θ1 is approximately larger than the angle θ2, but is not limited thereto. this.

The two first color sub-pixels SP1 are disposed on the central vertical line CVL of the associated pixel group G, that is, the central vertical line CVL passes through the two first color sub-pixels SP1. In addition, the first pair of subpixels SPA and the second pair of subpixels SPB are arranged along a central horizontal line CHL of the associated pixel group G, and the first pair of subpixels SPA and the second pair of subpixels SPB are respectively located at the center Two symmetrical positions on opposite sides (or two different sides) of the vertical line CVL. Since the first pair of subpixels SPA is composed of two second color subpixels SP2, and the second pair of subpixels SPB is composed of two third color subpixels SP3, the first pair here The pixel SPA and the second pair of sub-pixels SPB are respectively located at two symmetric positions on opposite sides of the central vertical line CVL The above refers to the respective centers of the shapes of the two second color sub-pixels SP2 in the first pair of sub-pixels SPA and the two third color sub-pixels SP3 in the second pair of sub-pixels SPB (or For the centroid) X2 and X3 are respectively located on the central horizontal line CHL, that is, the central horizontal line CHL passes through the centers X2 and X3, and the centers X2 and X3 respectively maintain the same distance from the central vertical line CVL.

In the same pixel group G, the two first color sub-pixels SP1 are respectively located at two symmetric positions on opposite sides of the central horizontal line CHL, that is, the central horizontal line CHL does not pass through the two first color sub-pixels SP1. . In other words, the centers (or called centroids) X1 of the two first color sub-pixels SP1 are respectively disposed on the central vertical line CVL, that is, the central vertical line CVL passes through the center of the two first color sub-pixels SP1 (or It is called a centroid) X1, and the center X1 of each of the two first color sub-pixels SP1 is maintained at about the same distance from the central horizontal line CHL, respectively. In addition, the two second color subpixels SP2 of the first pair of subpixels SPA and the two third color subpixels SP3 of the second pair of subpixels SP2 are respectively located on opposite sides of the central horizontal line CHL. Location. That is, the centers (or called centroids) X5 of the respective centers (or centroids) X4 of the two second color sub-pixels SP2 and the two third color sub-pixels SP3 are respectively maintained with the central horizontal line CHL. The same distance, that is, the central horizontal line CHL does not pass through the respective centers X4 of the two second color sub-pixels SP2 and the respective centers X5 of the two third color sub-pixels SP3.

The long sides of the first color sub-pixels SP1 are, for example, arranged in parallel with the relatively long diagonal of the diamond. In the present embodiment, the relatively long diagonal line in the diamond shape is the central horizontal line CHL, and therefore, the first color sub-pixels SP1 are in the horizontal direction DX. The length L1 is greater than the length L2 of the first color subpixel SP1 in the vertical direction DY.

In addition, the first distance T1 of the center line (or called the centroid connection) of the adjacent two first color sub-pixels SP1 in the horizontal direction DX, that is, the two adjacent pictures in the horizontal direction DX The first distance T1 of the center line of the two first color sub-pixels SP1 in the prime group G is greater than the second distance T2 of the center line of the adjacent two first color sub-pixels SP1 in the vertical direction DY That is, the second distance T2 of the center line of the two first color sub-pixels SP1 in the same pixel group G in the vertical direction DY. For example, the ratio of the first distance T1 to the second distance T2 is approximately equal to 2, but is not limited thereto. In an embodiment, the ratio of the first distance T1 to the second distance T2 may be between about 1 and 2. In addition, the shapes of the two second color sub-pixels SP2 in the adjacent first pair of sub-pixels SPA in the horizontal direction DX and the two third color sub-pixels SP3 in the second pair of sub-pixels SPB The third distance T3 of the center line (or the centroid connection), that is, the two second color sub-pixels SP2 and the two of the two adjacent pixel groups G in the horizontal direction DX The third distance T3 of the center line of the shape formed by the three-color sub-pixel SP3 is larger than the adjacent first pair of sub-pixels SPA in the vertical direction DY and the fourth line of the center of the second pair of sub-pixels SPB The distance T4, that is, the center of the shape formed by the two second color sub-pixels SP2 and the two third color sub-pixels SP3 in the two adjacent pixel groups G in the vertical direction DY The fourth distance T4. Or to say that the third distance T3 of the center line of the shape formed by the two second color sub-pixels SP2 in the same pixel group G in the horizontal direction DX and the two third color sub-pixels SP3 Greater than the center of the adjacent first pair of subpixels SPA and the second pair of subpixels SPB in the vertical direction DY The fourth distance T4, that is, the center of the shape formed by the two second color sub-pixels SP2 and the two third color sub-pixels SP3 in the two adjacent pixel groups G in the vertical direction DY The fourth distance of the line is T4. For example, the ratio of the third distance T3 to the fourth distance T4 is approximately equal to 2, but is not limited thereto. In an embodiment, the ratio of the third distance T3 to the fourth distance T4 may be between 1 and 2. It should be noted that there is no sub-picture on the center line of the adjacent two first color sub-pixels SP1 and the center line of the adjacent first pair of sub-pixels SPA and the second pair of sub-pixels SPB. Prime. That is to say, there is no configuration (or called presence) on the center line of the adjacent two first color sub-pixels SP1 and the center line of the adjacent first pair of sub-pixels SPA and the second pair of sub-pixels SPB. Any one of the first color subpixel SP1, the second color subpixel SP2, and the third color subpixel SP3. Furthermore, in the same pixel group G, the distance between one of the two first color sub-pixels SP1 and the center of one of the two second color sub-pixels SP2 and the two third color sub-pictures The distance of the center line of one of the SP3s is greater than the distance between the center lines of the two second color sub-pixels SP2 in the same pixel group G and in the vertical direction DY, and the two third color sub-pixels SP3 The distance from the center of the connection. Similarly, in the same pixel group G, the distance between the two first color sub-pixels SP1 and the center of the other two second color sub-pixels SP2 and the two third color sub-pictures The distance between the other center line of the prime SP3 is greater than the distance between the center lines of the two second color sub-pixels SP2 in the same pixel group G and in the vertical direction DY, and the two third color sub-pixels SP3 The distance from the center of the connection. However, in the same pixel group G and in the horizontal direction DX, two of the second color sub-pixels SP2 and one of the two third color sub-pictures The distance between the center line of one of the SP3s and the distance between the other two second color sub-pixels SP2 and the center line of the other of the two third color sub-pixels SP3 is greater than that in the same pixel group G, The distance between one of the two first color sub-pixels SP1 and the center line of one of the two second color sub-pixels SP2 and the center line of one of the two third color sub-pixels SP3 and In the same pixel group G, the distance between the two first color sub-pixels SP1 and the center of the other two second color sub-pixels SP2 and the two third color sub-pixels SP3 The distance from the center of the connection.

2 is a partial top plan view showing a pixel arrangement structure of a display of a comparative example. Referring to FIG. 2, in the comparative example, the pixel groups GC are arranged in the vertical direction DY and the horizontal direction DX to form a two-dimensional array. Also, in this two-dimensional array, sub-pixels adjacent in the vertical direction DY display the same color. In other words, the first color sub-pixel SP1, the second color sub-pixel SP2, and the third color sub-pixel SP3 are each arranged in the vertical direction DY, and the first color sub-pixel SP1, the second color sub-pixel SP2, and the first The three-color sub-pixels SP3 are alternately arranged in the horizontal direction DX. That is to say, a second color sub-pixel SP2 and a third color sub-pixel SP3 are arranged (or exist) on the center line of two adjacent first color sub-pixels SP1 in the horizontal direction DX.

Taking an organic light-emitting display as an example, a method of forming a display medium pattern corresponding to a comparative example may be a Slit type Fine Metal Mask (Slit type FMM) or a Slot type Fine Metal Mask (Slot type Fine Metal Mask). Slot type FMM) performs vapor deposition of the display medium material. For slotted metal masks, it is available To form a strip-shaped display medium pattern to cover all sub-pixels of the same color arranged in the vertical direction DY. Since the opening for forming the strip-shaped display medium pattern in the slit type metal mask is relatively narrow, the slit type metal mask is liable to cause color mixing problems due to uneven tension. In addition, since the sub-pixels adjacent in the horizontal direction DX are different colors, between the first color sub-pixel SP1 and the second color sub-pixel SP2 adjacent in the horizontal direction DX, the adjacent second An appropriate and equal spacing P1 between the color subpixel SP2 and the third color subpixel SP3 and between the adjacent third color subpixel SP3 and the first color subpixel SP1 should be maintained to avoid opening The slit metal mask is displaced to cause color mixing problems. Therefore, the aperture ratio of each sub-pixel in the horizontal direction DX is difficult to increase.

Compared with the slit type metal mask, the slotted metal mask can form an opening for vaporizing the display medium pattern for each sub-pixel, so that the tension of the slotted metal mask is relatively balanced, which helps Improve color mixing problems caused by uneven tension. However, since the slotted metal mask has its processing limit, the pitch P2 of two adjacent identical color sub-pixels in the plurality of sub-pixels in the vertical direction DY cannot be effectively reduced, so that each sub-pixel is vertical The aperture ratio in the direction DY cannot be effectively increased. In other words, the aperture ratio of the pixel arrangement structure of the comparative example is limited by the arrangement of the sub-pixels and cannot be effectively improved.

Referring to FIG. 1 and FIG. 2, compared with the pixel arrangement structure of the comparative example, the present embodiment adopts two pairs of sub-pixels (including the first pair of sub-pixels SPA and the second pair) in the same pixel group G. Sub-pixel SPB) is designed with the first color sub-pixel SP1 misaligned (or called misalignment), that is, in the same pixel group G, two pairs of sub-pixels The center will not be located on the center line of two adjacent first color sub-pixels SP1, that is, in the same pixel group G, the center connection of the two first color sub-pixels SP1 will not pass two pairs of pictures. The center of the prime, to reduce the distance between the two pairs of sub-pixels and the first color sub-pixel SP1 in the horizontal direction DX and the vertical direction DY, thereby facilitating the alignment of the two pairs of sub-pixels with the first color sub-pixel SP1 More closely. For example, any one of the two first color sub-pixels SP1 does not overlap with the two pairs of sub-pixels regardless of the projection in the horizontal direction DX and/or the vertical direction DY. In addition, since each pair of sub-pixels (including the first pair of sub-pixels SPA and the second pair of sub-pixels SPB) is located between four adjacent first-color sub-pixels SP1, each pair of sub-pixels is in the graph Both design and dimensional design can have a relatively high margin. For example, each pair of sub-pixels may extend in the horizontal direction DX and the vertical direction DY, respectively, to help greatly increase the aperture ratio. Similarly, since each first color subpixel SP1 is located between two adjacent pairs of first pair of subpixels SPA and two pairs of second pair of subpixels SPB, each first color subpixel SP1 is in graphic design. Or a dimensional design can also have a relatively high margin. For example, each of the first color sub-pixels SP1 may extend in the horizontal direction DX and the vertical direction DY, respectively, to help greatly increase the aperture ratio. In other words, compared to the comparative example, the pixel arrangement structure 100 of the display of the present embodiment may be such that the sub-pixels (including the first color sub-pixel SP1, the second color sub-pixel SP2, and the third color sub-pixel SP3) When the arrangement is tight, the aperture ratio of each sub-pixel is greatly improved. Therefore, the pixel arrangement structure 100 of the display of the present embodiment can improve the resolution of the display, taking into consideration both the resolution and the display quality.

In addition, in the same pixel group G, two sub-pictures of the same color can be made. Sharing a display medium pattern, for example, two first color sub-pixels SP1 in the same pixel group G share a green display medium pattern, and two second color sub-pixels SP2 share a red display medium pattern, and The two third color sub-pixels SP3 share a blue display medium pattern. In other words, two adjacent sub-pixels of the same color in the same pixel group G can be covered by the same display medium pattern, so that when the display medium pattern is created, it is not necessary to intentionally separate two adjacent The sub-pixel of color.

The above embodiment only schematically illustrates one embodiment of the pixel arrangement structure of the display, but the shape and size of the first color subpixel SP1, the second color subpixel SP2, and the third color subpixel SP3. It is not limited to those shown in FIG. For example, any one of the shapes of the first color subpixel SP1, the second color subpixel SP2, and the third color subpixel SP3 (including two second color subpixels SP2 and two third colors) The shape of the sub-pixel SP3 can be other kinds of polygons, such as a triangle, a quadrangle, a pentagon, a hexagon, or a circle.

In addition, as shown in the pixel arrangement structure 100A of the display of FIG. 3, the two sub-pixels of each pair of sub-pixels (including the first pair of sub-pixels SPA and the second pair of sub-pixels SPB) may also be different colors. . Specifically, each pair of sub-pixels may be combined by a second color sub-pixel SP2 and a third color sub-pixel SP3, respectively. Furthermore, a second color subpixel SP2 and a third color subpixel SP3 of each pair of subpixels are defined in FIG. 1 by X2~X5, T1~T4 and other definitions as shown in FIG. description. For example, in the same pixel group G, one of the two first color sub-pixels SP1 and the third color sub-pixel SP3 in the first pair of sub-pixels SPA respectively And the distance of the centroid connection of the second color subpixel SP2 in the second pair of subpixels SPB is greater than the third color subpixel SP3 of the first pair of subpixels SPA in the same pixel group G and The distance between the centroid of the second color subpixel SP2 and the centroid connection of the second color subpixel SP2 of the second pair of subpixels SPB and the third color subpixel SP3. In the same pixel group G, the other of the two first color subpixels SP1 and the second color subpixel SP2 in the first pair of subpixels SPA and the second pair of subpixels SPB The distance of the centroid connection of the three-color sub-pixel SP3 is greater than that of the third-color sub-pixel SP3 of the first pair of sub-pixels SPA and the second-color sub-pixel SP2 in the same pixel group G The distance of the line is the distance from the centroid connection of the second color subpixel SP2 of the second pair of subpixels SPB and the third color subpixel SP3. In the same pixel group G, the distance between the third color subpixel SP3 in the first pair of subpixels SPA and the centroid connection of the second color subpixel SP2 in the second pair of subpixels SPB and The distance between the second color subpixel SP2 in the first pair of subpixels SPA and the centroid connection of the third color subpixel SP3 in the second pair of subpixels SPB is greater than in the same pixel group G The distance between the third color subpixel SP3 of the first pair of subpixels SPA and the centroid of the second color subpixel SP2 and the second color subpixel SP2 of the second pair of subpixels SP2 and the third The distance of the centroid of the color sub-pixel SP3. Therefore, the centers (or called centroids) X1 of the two first color sub-pixels SP1 are respectively disposed on the central vertical line CVL, that is, the central vertical line CVL passes through the center of the two first color sub-pixels SP1 (or Called centroid) X1, and the second color subpixel SP2 and the third color subpixel SP3 in the first pair of subpixels SPA and the second color subpixels SP2 and third in the second pair of subpixels SPB The center of each shape of the color sub-pixel SP3 (Or called centroid) X2, X3 are respectively located on the central horizontal line CHL, that is, the central horizontal line CHL passes through the center X2, X3, and the centers X2, X3 respectively maintain the same distance from the central vertical line CVL, and the like.

Under this architecture, the sub-pixels (including the first color sub-pixel SP1 and the second color sub-picture can also be achieved by the design of two pairs of sub-pixels and the first color sub-pixel SP1 misaligned. The arrangement of the prime SP2 and the third color sub-pixel SP3) is compact, and the aperture ratio of each sub-pixel is greatly improved. In addition, in this embodiment, the two first color sub-pixels SP1 of the same color in the same pixel group G can also share one display medium pattern, and the different pixel groups G are adjacent in the vertical direction DY. The two second color sub-pixels SP2 (or the third color sub-pixels SP3) share a display medium pattern, so that when the display medium pattern is created, it is not necessary to intentionally separate two adjacent sub-pixels of the same color.

The shapes of the first color subpixel SP1, the second color subpixel SP2, and the third color subpixel SP3 of the embodiment and their arrangement manners may be changed according to different design requirements. For example, the shapes of the first color subpixel SP1, the second color subpixel SP2, and the third color subpixel SP3 may be other kinds of polygons, such as a triangle, a quadrangle, a pentagon, a hexagon, or a circle. Wait.

In addition, the respective extending directions of the first color subpixel SP1, the second color subpixel SP2, and the third color subpixel SP3 are not limited to those illustrated in FIG. For example, the extending direction of at least one of the first color sub-pixel SP1, the second color sub-pixel SP2, and the third color sub-pixel SP3 may be different from the horizontal direction DX. As shown in the pixel arrangement structure 100B of the display of FIG. 4, the first of each pixel group G The extending direction of the sub-pixel SPA and the second pair of sub-pixels SPB may also be substantially parallel to the vertical direction DY. Specifically, each pixel group G may further have two auxiliary vertical lines SVL that are substantially parallel to the central vertical line CVL, respectively. The two auxiliary vertical lines SVL are respectively located on opposite sides of the central vertical line CVL, and the two auxiliary vertical lines SVL are respectively maintained at substantially the same distance from the central vertical line CVL. In other embodiments, they may be different, but need to conform to the manner in which the misalignment arrangement described below is implemented. The two second color subpixels SP2 of the first pair of subpixels SPA and the two third color subpixels SP3 of the second pair of subpixels SPB may be respectively located on opposite sides of the auxiliary vertical line SVL. Location. That is, the center X5 of each of the two second color sub-pixels SP2 and the center X5 of the two third color sub-pixels SP3 are respectively substantially the same distance from the auxiliary vertical line SVL, but not limited thereto. Therefore, the two first color subpixels SP1 are located on the central vertical line CVL, that is, the central vertical line CVL passes through two first color subpixels SP1 (centroid), and the second color subpixels SP2 and II The third color sub-pixel SP3 is located on the central horizontal line CHL, that is, the central horizontal line CHL passes through two second color sub-pixels SP2 (centroid) and two third color sub-pixels SP3 (centroid), and the rest is described. See the examples below.

In this architecture, the pair of sub-pixels (including the first pair of sub-pixels SPA and the second pair of sub-pixels SPB) may be misaligned with the first color sub-pixel SP1 (or referred to as a misalignment). The design, that is, in the same pixel group G, the centers of the two pairs of sub-pixels are not located at the center line of the adjacent two first color sub-pixels SP1, that is, in the same pixel group G. The center line of the two first color sub-pixels SP1 does not pass through the center of the two pairs of sub-pixels to achieve the sub-pixel (including the first color sub-pixel The SP1, the second color subpixel SP2, and the third color subpixel SP3) are closely arranged, and the aperture ratio of each subpixel is greatly improved. For example, any one of the two first color sub-pixels SP1 does not overlap with the two pairs of sub-pixels regardless of the projection in the horizontal direction DX and/or the vertical direction DY. In addition, in this embodiment, two sub-pixels of the same color in the same pixel group G can also share one display medium pattern, so that when the display medium pattern is created, it is not necessary to intentionally distinguish two adjacent colors of the same color. Sub-pixel.

5 and 6 are partial top plan views, respectively, of a pixel arrangement structure of two displays in accordance with a second embodiment of the present invention. Referring to FIG. 5, the pixel arrangement structure 200 of the display of the present embodiment is substantially the same as the pixel arrangement structure 100B of the display of FIG. 4, and the same components are denoted by the same reference numerals and will not be described again. The main difference between the pixel arrangement structure 200 of the display and the pixel arrangement structure 100B of the display is that the central vertical line CVL of the present embodiment is a relatively long diagonal of the diamond, and the central horizontal line CHL is, for example, a relatively short pair of diamonds. Corner line. Therefore, the angle θ2 between the first axial direction D1 (or the second axial direction D2) and the central horizontal line CHL is greater than the angle θ1 between the first axial direction D1 (or the second axial direction D2) and the central vertical line CVL, and The description of the angles θ1 and θ2 can be referred to the foregoing description.

Further, the length L2 of each of the first color sub-pixels SP1 in the vertical direction DY is greater than the length L1 of the first color sub-pixel SP1 in the horizontal direction DX, and the adjacent two first color sub-pictures in the vertical direction DY The fifth distance T5 of the center line of the prime SP1 is greater than the sixth distance T6 of the center line (or called the centroid connection) of the adjacent two first color sub-pixels SP1 in the horizontal direction DX, that is, in the same picture In the prime group G, the fifth distance T5 of the center line of the two first color sub-pixels SP1 is greater than the horizontal direction The sixth distance T6 of the center line of the two first color sub-pixels SP1 in the two adjacent pixel groups G on the DX. Or to say that the fifth distance T5 of the center line of the adjacent two first color sub-pixels SP1 in the vertical direction DY, that is, in the two adjacent pixel groups G in the vertical direction DY The fifth distance T5 of the center line of the two first color sub-pixels SP1 is greater than the sixth distance T6 of the center line of the adjacent two first color sub-pixels SP1 in the horizontal direction DX, that is, in the horizontal direction The sixth distance T6 of the center line of the two first color sub-pixels SP1 in the two adjacent pixel groups G on the DX. For example, the ratio of the fifth distance T5 to the sixth distance T6 is equal to 2, but is not limited thereto.
