Detailed Description

Features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention. In the drawings and the following description, at least some well-known structures and techniques have not been shown in detail in order to avoid unnecessarily obscuring the present invention; also, the dimensions of some of the structures may be exaggerated for clarity. Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Referring to fig. 1, a pixel arrangement structure of a conventional organic light emitting display device such as a mobile phone, a watch, a car television, and the like employs a plurality of rectangular sub-pixels a, and the rectangular sub-pixels a are spaced apart from each other at an equal interval d in a column direction, resulting in light-emitting regions and non-light-emitting regions of pixel units forming stripes of alternating light and dark when the display device emits light. For example, when the monochrome sub-pixels of the pixel arrangement structure emit light, if the distance d between each adjacent sub-pixel a is small, a relatively obvious bright and dark stripe will appear on the display panel; when three color sub-pixels in the pixel arrangement structure emit light to form a white picture, if the distance d between each two adjacent sub-pixels a is large, a relatively obvious bright and dark stripe will be presented on the display panel, which seriously affects the display effect of the display device.

In order to reduce the light and dark stripes formed when the display device emits light, the embodiment of the invention provides a novel pixel arrangement structure.

For a better understanding of the present invention, embodiments of the present invention are described in detail below with reference to fig. 2 to 12.

Referring to fig. 2, the embodiment of the present invention provides a pixel arrangement structure including a plurality of repeating units 10 arranged in rows and columns along a first direction X and a second direction Y intersecting each other. Preferably, the included angle between the first direction X and the second direction Y is 90 degrees, so that the sub-pixels 1 of the plurality of repeating units 10 can be repeatedly arranged along the row direction and the column direction, and the structure is simple and the manufacturing is convenient.

The repeating unit 10 includes a plurality of sub-pixels 1 having different colors, and the plurality of sub-pixels 1 having different colors may form one pixel unit emitting light. The plurality of sub-pixels 1 are aligned along the first direction X, a non-light-emitting region is formed between two adjacent sub-pixels 1, and the shape of the non-light-emitting region is a concave polygon, as shown by a region surrounded by a dotted line and edges of two adjacent sub-pixels 1 in fig. 2.

The concave polygon 2 includes at least one reflex angle larger than 180 °, and a plurality of straight-line distances parallel to the first direction X from a vertex of one sub-pixel 1 to an edge of an adjacent sub-pixel 1 are provided, and at least two of the straight-line distances are not equal. For example, as shown in fig. 2, a first distance d1, a second distance d2, a third distance d3, and a fourth distance d 4. The first distance d1, the second distance d2, the third distance d3 and the fourth distance d4 may be different from each other, or may be equal to each other two by two, for example, d1 is d4, d2 is d3, or only d2 is d 3. In this way, the adjacent two sub-pixels 1 are arranged at an irregular distance in the first direction X, so that the light and dark stripes formed when the display device adopting the pixel arrangement structure emits light can be reduced or even eliminated.

Therefore, two adjacent sub-pixels 1 in the pixel arrangement structure are arranged at an irregular distance in the first direction X, and when a single-color sub-pixel emits light or three color sub-pixels emit light to form a white picture, the display panel adopting the pixel arrangement structure can reduce or even eliminate light and shade alternate stripes formed during light emission.

According to the pixel arrangement structure provided by the embodiment of the invention, the non-light-emitting areas between the two adjacent sub-pixels 1 are arranged at irregular distances in the concave polygon 2 formed by the non-light-emitting areas between the two adjacent sub-pixels 1 of the repeating unit 10, so that light and dark stripes formed when a display device adopting the pixel arrangement structure emits light can be reduced or even eliminated, and the display effect of the display device is further improved.

The specific structure of the pixel arrangement structure provided by the embodiment of the present invention is described in further detail below with reference to the accompanying drawings.

In the repeating unit 10, the sub-pixels 1 are convex polygons with the same shape, and the shape of the convex polygons may include, for example, but not limited to, polygons such as triangles, squares, trapezoids, rhombuses, pentagons, and hexagons. The longest side of the sub-pixel 1 is disposed at an inclination angle θ with respect to the first direction X, and the inclination angle θ satisfies the following condition: theta is more than 0 degree and less than 90 degrees. When the shape of the sub-pixel 1 is a regular polygon, the longest side thereof is any one side of the regular polygon.

Referring to fig. 2, 3 and 4, the repeating unit 10 has three sub-pixels with different colors, and the number of sides of the concave polygon 2 formed by the non-light emitting region between two adjacent sub-pixels 1 is greater than or equal to 5.

As shown in fig. 2, in the repeating unit 10, the sub-pixels 1 have a rectangular shape, the longest side of the sub-pixels 1 is disposed at an inclination angle θ to the first direction X, and the inclination angles θ of the sub-pixels 1 are equal.

In the concave polygon 2 formed by the non-light-emitting regions between two adjacent sub-pixels 1, distances from a vertex of one sub-pixel 1 to an edge of the adjacent sub-pixel 1 and parallel to the first direction X include a first distance d1, a second distance d2, a third distance d3 and a fourth distance d4, the first distance d1 is equal to the fourth distance d4, the second distance d2 is equal to the third distance d3, and d1 ≠ d2, so that the two adjacent sub-pixels 1 are arranged at irregular distances. It is understood that when the inclination angles θ of the plurality of sub-pixels 1 in the repeating unit 10 are not equally arranged, the first distance d1, the second distance d2, the third distance d3 and the fourth distance may be different from each other, or only the first distance d1 and the fourth distance d4 are equal, or only the second distance d2 and the third distance d3 are equal. In this way, two adjacent sub-pixels 1 are arranged at an irregular distance in the first direction X, so that light and dark stripes formed when a display device adopting the pixel arrangement structure emits light can be reduced or even eliminated.

As shown in fig. 3, in the repeating unit 10, the sub-pixels 1 have a regular triangle shape, any one side of the sub-pixels 1 is disposed at an inclination angle θ with respect to the first direction X, and the inclination angles θ of the sub-pixels 1 are equal.

In the concave polygon 2 formed by the non-light-emitting regions between two adjacent sub-pixels 1, the distances from the vertex of one sub-pixel 1 to the edge of the adjacent sub-pixel 1 and parallel to the first direction X include a first distance d1, a second distance d2 and a third distance d3, the first distance d1 is equal to the third distance d3, and d1 ≠ d2, so that the two adjacent sub-pixels 1 are arranged at irregular distances.

It is understood that when the inclination angles θ of the plurality of sub-pixels 1 in the repeating unit 10 are not equally disposed, the first distance d1, the second distance d2, and the third distance d3 may be different from each other. In this way, two adjacent sub-pixels 1 are arranged at an irregular distance in the first direction X, so that light and dark stripes formed when a display device adopting the pixel arrangement structure emits light can be reduced or even eliminated.

As shown in fig. 4, in the repeating unit 10, the subpixels 1 have a hexagonal shape, the longest side thereof is disposed at an inclination angle θ with respect to the first direction X, and the inclination angles θ of the subpixels 1 are equal.

In the concave polygon 2 formed by the non-light-emitting regions between two adjacent sub-pixels 1, distances from a vertex of one sub-pixel 1 to an edge of the adjacent sub-pixel 1 and parallel to the first direction X include a first distance d1, a second distance d2, a third distance d3 and a fourth distance d4, the first distance d1 is equal to the fourth distance d4, the second distance d2 is equal to the third distance d3, and d1 ≠ d2, so that the two adjacent sub-pixels 1 are arranged at irregular distances.

It is understood that when the inclination angles θ of the plurality of sub-pixels 1 in the repeating unit 10 are not equally arranged, the first distance d1, the second distance d2, the third distance d3 and the fourth distance d4 may be different from each other, or only the first distance d1 is equal to the fourth distance d4, or only the second distance d2 is equal to the third distance d 3. In this way, the non-light emitting regions between two adjacent sub-pixels 1 are arranged at irregular distances in the first direction X, so that the light and dark stripes formed when the display device adopting the pixel arrangement structure emits light can be reduced or even eliminated.

Further, in the repeating unit 10, the plurality of sub-pixels 1 different in color include at least a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B. In order to improve the display effect of the display device, the repeating unit 10 may further include a fourth sub-pixel N, the color of which may be any one of cyan, yellow and white. When the colors of the fourth sub-pixel N are cyan and yellow, the color gamut of the entire display device may be improved. When the color of the fourth sub-pixel N is white, the brightness of the entire display device can be improved, the brightness of the single color of red, green and blue in the single sub-pixel can be reduced, and the service life of the display device can be prolonged.

Preferably, in the repeating unit 10, the shape and the area of the plurality of sub-pixels 1 with different colors are the same, so as to facilitate the manufacturing, as shown in fig. 2, 3, and 4.

The pixel arrangement structure of the embodiment of the present invention is further described in detail below by taking the red sub-pixel R, the green sub-pixel G, and the blue sub-pixel B as the sub-pixels 1 with different colors in the repeating unit 10.

Referring to fig. 5, 6 and 7, schematic diagrams illustrating an effect of a pixel array formed by a plurality of repeating units of the pixel arrangement structures shown in fig. 2, 3 and 4 are shown, respectively.

As shown in fig. 5, 6 or 7, the repeating units 10 include three sub-pixels with different colors, namely a red sub-pixel R, a green sub-pixel G and a blue sub-pixel B, the repeating units 10 are aligned in a first direction X in a translation manner, and a non-light emitting region formed between two adjacent repeating units 10 along the first direction X is in the shape of a concave polygon 2. In the pixel array, the repeating unit 10 of the ith row and the repeating unit 10 of the (i + 1) th row are arranged in mirror symmetry, wherein i is a positive integer.

In the pixel array, as a whole, the repeating units 10 in the odd-numbered rows are arranged in a translational alignment manner, the repeating units 10 in the even-numbered rows are arranged in a translational alignment manner, and the plurality of repeating units 10 in two adjacent rows are arranged in a mirror symmetry manner in the second direction Y.

As also shown in fig. 5, 6 or 7, the repeating units 10 are repeatedly arranged in the first direction X; a single-color sub-pixel column is formed along the second direction Y. For example, in the second direction Y, the red sub-pixels R, the green sub-pixels G, and the blue sub-pixels B are respectively arranged in rows, and the red sub-pixels R, the green sub-pixels G, and the blue sub-pixels B in two adjacent rows are respectively arranged in mirror symmetry, so that two adjacent rows of sub-pixels 1 are arranged at irregular distances, and therefore, stripes formed by light and dark when the display device emits light can be eliminated, and the display effect of the display device is further improved.

In addition, the mask plates corresponding to the red sub-pixel R, the green sub-pixel G and the blue sub-pixel B can share one long and thin opening, so that the manufacturing difficulty of the mask plates is reduced.

Referring to fig. 8, 9 and 10, schematic diagrams illustrating an effect of another pixel array formed by a plurality of repeating units of the pixel arrangement structures shown in fig. 2, 3 and 4 are shown, respectively.

The repeating unit 10 includes three sub-pixels with different colors, namely a red sub-pixel R, a green sub-pixel G and a blue sub-pixel B, the plurality of repeating units 10 are arranged in a pixel array, in the pixel array, the plurality of repeating units 10 are arranged in m rows in the second direction Y, n repeating units 10 are arranged in each row, and a non-light emitting region formed between two adjacent repeating units 10 along the first direction X is shaped as a concave polygon 2, as shown in a region surrounded by a solid line and edges of two adjacent sub-pixels 1 in fig. 8, 9 and 10.

Further, in the pixel array, the repeating unit 10 of the j-th row is arranged in a translational alignment with the repeating unit 10 of the j + 2-th row. The sub-pixel 1 of one color in the ith repeating unit 10 in the jth row and the sub-pixel 1 of the same color in the ith repeating unit 10 in the jth +1 row are arranged in mirror symmetry in the second direction Y; the sub-pixels 1 of the rest colors in the ith repeating unit 10 in the jth row and the sub-pixels 1 of the rest colors in the ith repeating unit 10 in the jth +1 row are respectively symmetrical in the second direction Y and arranged diagonally in pairs, wherein i and j are positive integers.

In the pixel array, the arrangement of the repeating units 10 in the odd-numbered rows is the same, and the arrangement of the repeating units 10 in the even-numbered rows is the same; and for example, the green sub-pixel G in the ith repeating unit 10 of the j-th row is arranged in mirror symmetry with the green sub-pixel G in the ith repeating unit 10 of the j + 1-th row in the second direction Y. The red sub-pixel R and the blue sub-pixel B in the ith repeating unit 10 in the jth row and the red sub-pixel R and the blue sub-pixel B in the ith repeating unit 10 in the jth +1 row are respectively symmetrical in the second direction Y and are arranged diagonally in pairs. For example, in the j-th row, the red sub-pixel R in the 1 st repeating unit 10 and the red sub-pixel R in the 1 st repeating unit 10 in the j +1 th row are separated by one column of sub-pixels and arranged diagonally, and the two blue sub-pixels B are separated by one column of sub-pixels and arranged diagonally.

Thus, the green sub-pixels G are in a row in a wave shape in the second direction Y. The red sub-pixel R and the blue sub-pixel B are respectively symmetrical in the second direction Y and are arranged in a pairwise opposite angle mode. Compared with the pixel arrangement structures in fig. 5, 6 and 7, the red sub-pixels R and the blue sub-pixels B are arranged in a row in a staggered manner along the second direction Y, and the display stripes can be reduced or even eliminated because the edges of the pixel array are two colors distributed in a staggered manner along the second direction Y. The two adjacent columns of sub-pixels 1 are arranged at irregular distances, so that light and shade alternate stripes formed when the display device emits light can be reduced or even eliminated, and the display effect of the display device is improved.

In addition, since the plurality of repeating units 10 are arranged in the row of the green sub-pixels G in the second direction Y, the metal mask plates corresponding to the plurality of green sub-pixels G can share one long and thin opening, thereby reducing the difficulty in manufacturing the mask plates.

Fig. 11 and 12 are schematic diagrams illustrating the effect of two pixel arrays formed by adding a fourth sub-pixel to the plurality of repeating units of the pixel arrangement structure shown in fig. 4.

As shown in fig. 11, the repeating unit 10 includes four sub-pixels with different colors, namely a red sub-pixel R, a green sub-pixel G, a blue sub-pixel B, and a fourth sub-pixel N. A plurality of repeating units 10 are arranged in a pixel array. As described above, when the colors of the fourth sub-pixel N are cyan and yellow, the color gamut of the entire display device may be improved. When the color of the fourth sub-pixel N is white, the brightness of the entire display device can be improved, the brightness of the single color of red, green and blue in the single sub-pixel can be reduced, and the service life of the display device can be prolonged.

The pixel array is similar to the pixel array in fig. 10 as a whole, except that the fourth sub-pixel N in the ith repeating unit 10 in the jth row and the fourth sub-pixel N in the ith repeating unit 10 in the (j + 1) th row are arranged in mirror symmetry in the second direction Y. For example, in the j-th row, the fourth sub-pixel N in the 1 st repeating unit 10 from left to right and the fourth sub-pixel N in the 1 st repeating unit 10 in the j +1 th row are arranged in mirror symmetry in the second direction Y.

Therefore, the green sub-pixel G and the fourth sub-pixel N are both in a wavy column in the second direction Y, and the green sub-pixel G and the fourth sub-pixel N in two adjacent rows are both arranged in mirror symmetry. In addition, the two adjacent columns of sub-pixels are arranged at irregular distances, so that light and shade alternate stripes formed when the display device emits light can be reduced or even eliminated, and the display effect of the display device is improved.

As shown in fig. 12, the repeating unit 10 includes four sub-pixels with different colors, namely a red sub-pixel R, a green sub-pixel G, a blue sub-pixel B, and a fourth sub-pixel N. A plurality of repeating units 10 are arranged in a pixel array.

As a whole, the pixel array is similar to the pixel array in fig. 10, except that the red sub-pixel R, the blue sub-pixel B, and the fourth sub-pixel N in the ith repeating unit 10 in the jth row are respectively symmetric in the second direction Y and arranged diagonally two by two with the red sub-pixel R, the blue sub-pixel B, and the fourth sub-pixel N in the ith repeating unit 10 in the (j + 1) th row. For example, in the j-th row, the red sub-pixel R in the 1 st repeating unit 10 and the red sub-pixel R in the 1 st repeating unit 10 in the j +1 th row are arranged diagonally with one column therebetween, the two blue sub-pixels B are arranged diagonally with two columns therebetween, and the two fourth sub-pixels N are arranged diagonally with two columns therebetween.

Therefore, the green sub-pixels G are in a wavy row along the second direction Y, and the green sub-pixels G in two adjacent rows are arranged in mirror symmetry. The remaining columns are two-color sub-pixels 1, for example, the red sub-pixel R and the fourth sub-pixel N are staggered in the second direction Y to form a column, the blue sub-pixel B and the red sub-pixel R are staggered in the second direction Y to form a column, and the fourth sub-pixel N and the blue sub-pixel B are staggered in the second direction Y to form a column. The two adjacent columns of sub-pixels are arranged at irregular distances, so that light and shade alternate stripes formed when the display device emits light can be reduced or even eliminated, and the display effect of the display device is improved.

In addition, the embodiment of the invention also provides a display panel, which comprises any one of the pixel arrangement structures.

As described above, since the two adjacent sub-pixels 1 in the pixel arrangement structure are arranged at an irregular distance in the first direction X, the display panel can reduce or even eliminate the light and dark stripes formed during light emission no matter the single-color sub-pixels emit light or the three-color sub-pixels emit light to form a white picture.

In addition, the embodiment of the invention also provides a display device, which comprises the display panel.

While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. It is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
