Description

Pixel arrangement structure, display panel and mask assembly

Technical Field

The present invention relates to the field of display technologies, and in particular, to a pixel arrangement structure, a display panel, and a mask assembly.

Background

An Organic Light-Emitting Diode (OLED) is an active Light-Emitting device. Compared with the traditional liquid crystal display (Liquid Crystal Display; LCD) display mode, the OLED display technology does not need a backlight lamp and has the self-luminous characteristic. The OLED adopts a thinner organic material film layer and a glass substrate, and when current passes through the OLED, the organic material emits light. Therefore, the OLED display panel can save electric energy remarkably, can be made lighter and thinner, can withstand a wider range of temperature changes than an LCD display panel, and has a larger viewing angle. The OLED display panel is expected to be the next generation flat panel display technology following the LCD, and is one of the most attention-paid technologies in the current flat panel display technology.

For a better understanding of the present invention, a pixel arrangement structure, a display panel, an electronic device, and a mask assembly according to embodiments of the present invention are described in detail below with reference to fig. 1 to 16.

Referring to fig. 1 and fig. 2 together, fig. 1 is a schematic structural diagram of a repeating unit 100 in a pixel arrangement structure according to an embodiment of the invention. Fig. 2 is a schematic diagram of a pixel arrangement structure according to an embodiment of the first aspect of the present invention.

According to the pixel arrangement structure provided by the embodiment of the invention, the pixel arrangement structure includes a plurality of repeating units 100 arranged in an array along a first direction (X direction in fig. 2) and a second direction (Y direction in fig. 2), and the repeating units 100 include: a first sub-pixel 110 having a quadrilateral shape and including two first long sides 111 disposed opposite to each other in a width direction (B direction in fig. 2) and two first wide sides 112 disposed opposite to each other in a length direction (L direction in fig. 2); the second sub-pixel 120 having a quadrilateral shape and including two second long sides 121 disposed opposite to each other in the width direction and two second wide sides 122 disposed opposite to each other in the length direction, the second sub-pixel 120 being disposed adjacent to the first long side 111 of the first sub-pixel 110 through the second long sides 121, and the length of the second long sides 121 being equal to the length of the first long side 111; the third sub-pixel 130 having a quadrilateral shape and including two third long sides 131 disposed opposite to each other in the width direction and two third wide sides 132 disposed opposite to each other in the length direction, the third sub-pixel 130 being disposed adjacent to the first wide side 112 of the first sub-pixel 110 through the third wide side 132, and the length of the third wide side 132 being equal to the length of the first wide side 112; the number of the first sub-pixels 110, the second sub-pixels 120 and the third sub-pixels 130 is 1:1:1, and the length direction and the width direction intersect with the second direction.

In the pixel arrangement according to the embodiment of the invention, the repeating unit 100 of the pixel arrangement includes a first sub-pixel 110, a second sub-pixel 120, and a third sub-pixel 130. The second sub-pixel 120 can reduce the interval between the second sub-pixel 120 and the first sub-pixel 110 by having the second long side 121 thereof disposed adjacent to the first long side 111 of the first sub-pixel 110. The third subpixel 130 is disposed adjacent to the first wide side 112 of the first subpixel 110 by its third wide side 132, which can reduce the pitch between the third subpixel 130 and the first subpixel 110.

The length of the second long side 121 is equal to the length of the first long side 111, and the length of the third wide side 132 is equal to the length of the first wide side 112, so that interference between the second sub-pixel 120 and the first sub-pixel 110 does not occur, and the distribution rate of the sub-pixels in a unit area can be improved.

The number ratio of the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 is 1:1:1, that is, the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 in one display unit are all true sub-pixels, and the situation that the sub-pixels are shared does not exist, so that the display effect of the pixel arrangement structure can be improved.

The length direction and the width direction are intersected with the second direction, so that the sawtooth situation of the edge of the pixel arrangement structure can be improved, and when the pixel arrangement structure is used for a special-shaped display area, the pixel arrangement structure can be better adapted to the edge of the special-shaped area. In addition, the length direction and the width direction are intersected with the second direction, so that two obvious stripes can be prevented from being formed in the second direction, and the display effect of pixel arrangement is further improved.

In addition, in the embodiment of the present invention, the first long side 111, the second long side 121, and the third long side 131 are all formed by extending in the length direction, and the first wide side 112, the second wide side 122, and the third wide side 132 are all formed by extending in the width direction. I.e., extending in the same direction, the first broadside 112, the second broadside 122, and the third broadside 132 extend in the same direction. The angle between the first long side 111 and the first wide side 112, the angle between the second long side 121 and the second wide side 122, and the angle between the third long side 131 and the third wide side 132 are the same. When the length of the second long side 121 is equal to the length of the first long side 111 and the length of the third wide side 132 is equal to the length of the first wide side 112, a notch 140 can be formed between the second subpixel 120 and the third subpixel 130.

In some alternative embodiments, in two repeating units 100 adjacent in the second direction, at least part of the first sub-pixel 110 of the previous repeating unit 100 is located in the notch 140 in the subsequent repeating unit 100.

In these alternative embodiments, when a portion of the repeating units 100 is located in the notch 140, the pitch between two adjacent repeating units 100 can be reduced, the pixel distribution rate per unit area can be improved, and the pixel density and display effect of the pixel arrangement structure can be improved.

Referring to fig. 3 together, fig. 3 illustrates an arrangement of two repeating units 100 adjacent to each other along a first direction in a pixel arrangement according to an embodiment of the first aspect of the invention.

According to the pixel arrangement structure provided in the embodiment of the invention, in two repeating units 100 adjacent along the first direction, the second wide edge 122 of the second sub-pixel 120 of the next repeating unit 100, which is close to the first sub-pixel 110, is collinear with the first wide edge 112 of the third sub-pixel 130 of the previous repeating unit 100, which is far from the first sub-pixel 110.

In these alternative embodiments, when the repeating units 100 are arranged in the above manner, in the latter repeating unit 100, the side of the first subpixel 110 facing away from the third subpixel 130 can just leave a relief space 150 adapted to the third subpixel 130, so that the third subpixel 130 of one of the two repeating units 100 adjacent in the second direction can be located in the relief space 150. The pitch of each of the repeating units 100 within the pixel arrangement can be reduced, thereby improving the pixel density and display effect of the pixel arrangement.

Optionally, the first direction is parallel to the width direction, so that the arrangement of the pixel arrangement structure can be simplified.

The first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 are arranged in various manners, for example, the first sub-pixel 110 is a blue sub-pixel, the second sub-pixel 120 is a red sub-pixel, and the third sub-pixel 130 is a green sub-pixel. In other embodiments, the first sub-pixel 110 may be a red sub-pixel or a green sub-pixel, the second sub-pixel 120 may be a blue sub-pixel or a green sub-pixel, and the third sub-pixel 130 may be a blue sub-pixel or a red sub-pixel, so long as the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 are sub-pixels with different colors.

The first subpixel 110 is exemplified as a blue subpixel. When the first subpixel 110 is a blue subpixel, the size of the first subpixel 110 is larger than the sizes of the second subpixel 120 and the third subpixel 130.

The blue sub-pixel typically has a lower luminous efficiency than the green and red sub-pixels. In these alternative embodiments, the larger size of the first sub-pixel 110, i.e., the larger size of the blue sub-pixel, can increase the area of the blue sub-pixel and increase the overall service life of the blue sub-pixel.

In other embodiments, please refer to fig. 4 to 5, fig. 4 is a schematic diagram illustrating a structure of a repeating unit 100 in a pixel arrangement according to another embodiment of the first aspect of the present invention. Fig. 5 is a schematic view of a pixel arrangement according to another embodiment of the first aspect of the invention.

According to the pixel arrangement structure provided in the embodiment of the invention, the size of the first sub-pixel 110 is equal to the size of the third sub-pixel 130, and the length of the third wide side 132 is equal to the length of the first long side 111.

In still other alternative embodiments, please refer to fig. 6 to fig. 7, fig. 6 is a schematic structural diagram of a repeating unit 100 in a pixel arrangement structure according to still another embodiment of the first aspect of the present invention. Fig. 5 is a schematic view of a pixel arrangement according to a further embodiment of the first aspect of the invention.

According to the pixel arrangement structure provided by the embodiment of the invention, the size of the first sub-pixel 110 is equal to the size of the second sub-pixel 120, and the length of the second wide side 122 is equal to the length of the first long side 111.

The second sub-pixel 120 and the third sub-pixel 130 are arranged in various sizes. Referring to fig. 8 and fig. 9 together, fig. 8 is a schematic structural diagram of a repeating unit 100 in a pixel arrangement structure according to another embodiment of the first aspect of the invention. Fig. 9 is a schematic view of a pixel arrangement structure according to still another embodiment of the first aspect of the invention.

According to a pixel arrangement structure provided in a further embodiment of the present invention, the second sub-pixel 120 and the third sub-pixel 130 have different sizes, and the second sub-pixel 120 has a size larger than the third sub-pixel 130. For example, the second sub-pixel 120 is a red sub-pixel, and the third sub-pixel 130 is a green sub-pixel. Because human eyes are more sensitive to green, in the pixel arrangement structure provided by the embodiment of the invention, the distribution area of green sub-pixels is smaller, and the phenomenon of green emission of the pixel arrangement structure can be improved.

In yet other alternative embodiments, referring to FIGS. 1-3, the first sub-pixel 110 and the second sub-pixel 120 are equal in size. The arrangement of the pixel arrangement structure can be simplified, the size of the vapor deposition opening on the mask plate for vapor deposition of the second sub-pixel 120 is the same as the size of the vapor deposition opening on the mask plate for vapor deposition of the third sub-pixel 130, and the distance between two adjacent vapor deposition openings is the same. The mask plate for evaporating the second sub-pixel 120 and the mask plate for evaporating the third sub-pixel 130 can use the same process, so that the preparation of the mask plate is simplified.

The second sub-pixel 120 and the third sub-pixel 130 have the same size in a plurality of ways, for example, the lengths of the first long side 111 and the first wide side 112 are different, and the lengths of the second wide side 122 and the third long side 131 are the same; or the first long side 111 and the first wide side 112 have the same length, and the second wide side 122 and the third long side 131 have different lengths.

With continued reference to fig. 1 to 9, the first sub-pixel 110 may be rectangular, and the second sub-pixel 120 and the third sub-pixel 130 may be rectangular, so that the included angle between the second direction and the width direction is 45 degrees.

In these alternative embodiments, the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 are all rectangular, so that the shapes of the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 can be simplified, and the shapes of the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 are more regular, so that the sub-pixels, the second sub-pixel 120 and the third sub-pixel 130 can be formed by vapor deposition. The included angle between the second direction and the width direction is 45 degrees, so that the display of oblique stripes is facilitated, and the edge of the special-shaped area can be well adapted. For example, when the pixel arrangement is used in a display panel, where holes are cut or notched, the pixel arrangement is better adapted to the edges of the hole cut or notched area when arranged in the manner described above.

Alternatively, referring to fig. 1 to 3, the first sub-pixel 110 is square, the length of the first long side 111 is equal to the length of the first wide side 112, and then the length of the second long side 121 is equal to the length of the third wide side 132. On the one hand, the shape of the repeating unit 100 is more regular, and the evaporation forming of the pixel arrangement structure is facilitated. On the other hand, it is convenient to make the second wide side 122 and the third long side 131 have the same size as the third sub-pixel 130 by reasonably setting the lengths of the second wide side 122 and the third long side 131 (for example, making the length of the second wide side 122 equal to the length of the third long side 131), and also to make the sizes of the second sub-pixel 120 and the third sub-pixel 130 smaller than the size of the first sub-pixel 110 (for example, making the length of the second wide side 122 smaller than the length of the first long side 111, and making the length of the third long side 131 smaller than the length of the first long side 111).

Referring to fig. 10 and fig. 11 together, fig. 10 is a schematic structural diagram of a repeating unit 100 in a pixel arrangement structure according to a further embodiment of the first aspect of the present invention. Fig. 11 is a schematic view of a pixel arrangement structure according to a further embodiment of the first aspect of the invention.

According to the pixel arrangement structure provided in the further embodiment of the present invention, the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 are all parallelograms, and the included angle between the first long side 111 and the first wide side 112 is smaller than 90 degrees, and the included angle between the second direction and the width direction is smaller than 45 degrees.

According to the pixel arrangement structure provided by the embodiment of the invention, the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 are all parallelograms, and the included angle between the first long side 111 and the first wide side 112 is smaller than 90 degrees, and the included angle between the second direction and the width direction can be adjusted by reasonably setting the included angle between the first long side 111 and the first wide side 112, so that the pixel arrangement structure can be better adapted to a special-shaped region.

When the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 are all parallelograms, and the included angle between the first long side 111 and the first wide side 112 is smaller than 90 degrees, the length of the first long side 111 may be equal to the length of the first wide side 112, and the first sub-pixel 110 is diamond-shaped.

Alternatively, referring to fig. 12 and fig. 13 together, fig. 12 is a schematic structural diagram of a repeating unit 100 in a pixel arrangement structure according to a further embodiment of the first aspect of the present invention. Fig. 13 is a schematic view of a pixel arrangement structure according to a further embodiment of the first aspect of the invention.

According to the pixel arrangement structure of the embodiment of the invention, when the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 are all parallelograms and the included angle between the first long side 111 and the first wide side 112 is smaller than 90 degrees, the length of the first long side 111 and the length of the first wide side 112 may be different. As shown in fig. 12 and 13, the length of the first long side 111 may be greater than the length of the first wide side 112. In other embodiments, the length of the first long side 111 may also be less than the length of the first wide side 112.

Referring to fig. 14 and 15 together, fig. 14 is a schematic structural diagram of a display panel according to a second embodiment of the invention, and fig. 15 is a schematic partial enlarged structural diagram of the display panel at I in fig. 14.

According to a second embodiment of the present invention, there is provided a display panel comprising the pixel arrangement of any one of the first embodiments described above. Since the display panel according to the embodiment of the present invention includes the pixel arrangement structure of any one of the first embodiments, the display panel according to the present invention has the beneficial effects of any one of the pixel arrangement structures of the first embodiment, and is not described herein.

In some alternative embodiments, the display panel includes a display area AA and a non-display area NA disposed around the display area AA. In other embodiments, the display panel may also include only the display area AA and not the non-display area NA. As can be seen from the local enlargement of the display area AA, the pixel arrangement structure of the display panel selects the above pixel arrangement structure.
