In order to solve the above technical problem, in the pixel structure provided in the embodiment of the present invention, in any two adjacent repeating units, the minimum distance between the sub-pixel a and the sub-pixel B located in the same repeating unit is smaller than the minimum distance between the sub-pixel a and the sub-pixel B located in another repeating unit, so that a light-transmitting gap is formed between any two adjacent repeating units, and thus the transmittance of the pixel structure can be improved, and the effect of the photosensitive element for acquiring an image is further improved.
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all 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.
The pixel structure provided by the embodiment of the invention comprises a plurality of repeating units which are regularly arranged, wherein the regular arrangement can refer to matrix arrangement; for example, a plurality of repeating units 110 may be arranged in the arrangement shown in fig. 1 at intervals along the first direction to form one repeating unit group 100, and in any two adjacent rows of repeating unit groups 100, the repeating units 110 in one row of repeating unit group 100 are arranged in a staggered manner with respect to the repeating units 110 in another row of repeating unit group 100. Therefore, the arrangement regularity of the repeating units can be ensured, the number of the repeating units 110 in a unit area is increased, and the resolution of the display panel is improved.
It is to be understood that the first direction may be a row direction (length direction) or a column direction (width direction) of the display panel, and for convenience of description, the present embodiment defines the first direction as the row direction of the display panel, i.e., the X direction in fig. 1.
The repeating unit 110 includes four sub-pixels, and the connecting lines of the centers of the four sub-pixels may form the first virtual quadrangle 120, that is, the centers of the four sub-pixels are respectively located at four vertices of the first virtual quadrangle 120, or the centers of the four sub-pixels are respectively coincident with the four vertices of the first virtual quadrangle 120.
For example, when the shape of the sub-pixel is a quadrangle, the center of the sub-pixel is the geometrical center of the quadrangle, that is, the intersection of two diagonal lines of the quadrangle.
At least three of the four sub-pixels have different light emission colors, for example, one of the four sub-pixels has a red light emission color, the other sub-pixel has a blue light emission color, and the remaining two sub-pixels have a green light emission color. For another example: the light emitting color of one sub-pixel is red, the light emitting color of the other sub-pixel is green, and the light emitting colors of the remaining two sub-pixels are blue. For another example: the light emitting color of one sub-pixel is green, the light emitting color of the other sub-pixel is blue, and the light emitting colors of the remaining two sub-pixels are red. For another example, the colors of the four sub-pixels are red, blue, green, and white, respectively.
In any two adjacent repeating units, the minimum distance between the sub-pixel A and the sub-pixel B in the same repeating unit is smaller than the minimum distance between the sub-pixel A and the sub-pixel B in the other repeating unit, so that a light-transmitting gap is formed between any two adjacent repeating units, the transmittance of a pixel structure can be improved, and the image obtaining effect of the photosensitive element is further improved.
The minimum distance mentioned in the embodiments of the present invention may be understood as a minimum distance between a center of the sub-pixel a and a center of the sub-pixel B, or may also be understood as a minimum distance between two opposite sides of the sub-pixel a and the sub-pixel B, and for convenience of description, the minimum distance is a minimum distance between a center of the sub-pixel a and a center of the sub-pixel B in the following description.
For example, taking the pixel structure shown in fig. 1 as an example, the sub-pixel a may also be a green sub-pixel, and the sub-pixel B may be a blue sub-pixel. In the same repeating unit, the minimum distance between the center of the sub-pixel a and the center of the sub-pixel B is a1, the minimum distance between the center of the sub-pixel a and the center of the sub-pixel B in another repeating unit adjacent to the repeating unit is a2, and a2 is greater than a 1.
For another example, as shown in fig. 1, the sub-pixel a may be a green sub-pixel, the sub-pixel B may be a red sub-pixel, the minimum distance between the center of the sub-pixel a and the center of the sub-pixel B in the same repeating unit is a3, the minimum distance between the center of the sub-pixel a and the center of the sub-pixel B in another repeating unit adjacent to the repeating unit is a4, and a4 is greater than a 3.
For another example, as shown in fig. 1, the sub-pixel a may also be a red sub-pixel, the sub-pixel B may be a blue sub-pixel, in the same repeating unit, the minimum distance between the center of the sub-pixel a and the center of the sub-pixel B is a5, the minimum distance between the center of the sub-pixel a and the center of the sub-pixel B in another repeating unit adjacent to the repeating unit is a6, and a6 is greater than a 5.
In the embodiment, through the design that a2 is greater than a1, a4 is greater than a3, and a6 is greater than a5, the light-transmitting gap 200 can be formed between any two adjacent repeating units, the transmittance of the pixel structure can be improved, and the effect of the photosensitive element for acquiring images is further improved.
In the present embodiment, the sub-pixels are all polygonal, such as triangular, quadrilateral, pentagonal, hexagonal or octagonal, wherein, when the four sub-pixels are triangular, the arrangement is as shown in fig. 2.
Preferably, the four sub-pixels are all in a diamond structure, and may be in a rectangle or a square, and one diagonal of the diamond structure is parallel to the first direction. The diamond structure can improve the utilization rate of the pixel structure to the space, and in the same space, the number of the sub-pixels can be increased, and the resolution of the pixel structure is improved. However, the shape of the sub-pixels is not limited to the polygonal shape, and the sub-pixels may be circular and arranged as shown in fig. 3. The embodiment sets the shape of the sub-pixel to be circular, which can facilitate the preparation of the sub-pixel.
In some embodiments, a light-transmitting gap is formed between any two adjacent repeating units 110, and a plurality of light-transmitting gaps are communicated with each other to form a mesh-shaped light-transmitting gap 200, so that the transmittance of the pixel structure can be increased, and the amount of light received by a photosensitive device (e.g., a fingerprint identification device or an under-screen camera) can be increased, thereby ensuring the identification accuracy and the imaging effect of the photosensitive device.
The mesh-shaped light-transmitting gap 200 is used for transmitting light rays supplied to a photosensitive device, wherein the photosensitive device is a camera, a sensor or other devices with biological characteristic identification capability, and the devices with biological characteristic identification capability can be used for fingerprint identification, palm print identification or face identification. In addition, the shape of the light-transmitting gap can be regular rectangular and irregular.
When the pixel structure is applied to the mobile phone, and the photosensitive element is the camera, the camera is located below the display panel of the mobile phone, when the mobile phone is started to take a picture, light can penetrate through the light-transmitting gap to enter the camera below the display panel, so that the light cannot be influenced by sub-pixels in the repeating unit, the interference of the repeating unit 110 on the image acquired by the camera is reduced, and the imaging effect of the camera is improved. In addition, the pixel structure designed by the embodiment of the invention is provided with the reticular light-transmitting gap 200, and light rays can pass through the display panel by utilizing the reticular light-transmitting gap 200 and enter the camera below the display panel.
Further, as shown in fig. 4, the mesh-shaped light-transmitting gap 200 includes a plurality of first light-transmitting gaps 210 and a plurality of second light-transmitting gaps 220 arranged to cross each other.
When the rhombus is square, the first light-transmitting gap 210 is parallel to the first side 122 in the rhombus; the second light-transmitting gap 220 is parallel to the second side 123 of the diamond, and the first side 122 intersects the second side 123. First printing opacity clearance 210 and second printing opacity clearance 220 are regular rectangle, and the wearing to establish of the light of being convenient for like this improves the formation of image ability of camera under the screen. Wherein a diamond shape is one case of the first virtual quadrangle 120.
As another alternative embodiment of the mesh-shaped light-transmitting gap 200, with reference to fig. 2, the mesh-shaped light-transmitting gap 200 includes a plurality of first light-transmitting gaps 210 and a plurality of second light-transmitting gaps 220 arranged to intersect with each other, and an included angle between the first light-transmitting gaps 210 and the first edge 122 in the diamond shape is an acute angle; the included angle between the second light-transmitting gap 220 and the second side 123 in the diamond shape is an acute angle, and the first side 122 intersects with the second side 123. Wherein a diamond shape is one case of the first virtual quadrangle 120.
When the included angle between the first light-transmitting gap 210 and the first side 122 and the included angle between the second light-transmitting gap 220 and the second side 123 are acute angles, the distance between the red sub-pixel and the blue sub-pixel in the same repeating unit 110 can be reduced, the compactness of the repeating unit 110 is improved, the number of the sub-pixels can be increased in the same space, and the resolution of the pixel structure is improved.
As shown in fig. 5, as an alternative embodiment of the repeating units 110, each repeating unit 110 includes a first sub-pixel 111, two second sub-pixels 112 and a third sub-pixel 113, wherein the two second sub-pixels 112 are located at two sides of the first sub-pixel 111 and the third sub-pixel 113.
When the sub-pixels in the repeating unit 110 are used to synthesize white light, taking the luminance of the white light as 100% as an example, the luminance occupied by the green sub-pixel is relatively high, for example, 70% of the luminance of the white light, so in this embodiment, the first sub-pixel 111 is set as a red sub-pixel, the second sub-pixel 112 is set as a green sub-pixel, and the third sub-pixel 113 is set as a blue sub-pixel.
The two green sub-pixels are located on both sides of the blue and green sub-pixels, that is, the two green sub-pixels are separated by the blue and green sub-pixels.
Meanwhile, the pixel structure provided by the embodiment of the present invention includes a plurality of rows of repeating unit groups 100, where each row of repeating unit group 100 includes a plurality of repeating units 110 arranged in the same row along a first direction; the two second sub-pixels 112 in each repeating unit 110 are arranged in the same row along the first direction; the repeating units 110 in the two adjacent rows of repeating unit groups 100 are arranged in a staggered manner, the first sub-pixel 111 in one row of repeating unit group 100 and the third sub-pixel 113 in the other row of repeating unit group 100 in the two adjacent rows are located in the same arrangement region, and each arrangement region extends along the first direction and the first sub-pixels and the third sub-pixels located in the same arrangement region are alternately arranged at intervals. The first sub-pixels 111 and the third sub-pixels 113 are alternately arranged at intervals in the same layout region, which means that each first sub-pixel 111 is located between two third sub-pixels 113, and each third sub-pixel 113 is located between two first sub-pixels 111.
According to the pixel structure provided by the embodiment of the invention, the first sub-pixel and the third sub-pixel which are positioned in the adjacent repeating units in the two adjacent rows are positioned in the same layout region, so that the space utilization rate of the pixel structure can be reasonably planned, the pixel density in a unit area is improved, and the resolution of a display panel is optimized.
In the embodiment, in each repeating unit 110 in the same row of repeating unit group, the first sub-pixels 111 are located in the same row (the central connecting line is a straight line), the second sub-pixels 112 are located in the same row (the central connecting line is a straight line), and the third sub-pixels 113 are located in the same row (the central connecting line is a straight line).
In this embodiment, the layout region does not have a special meaning, but only defines the arrangement range of the first sub-pixel and the second sub-pixel. The central connecting lines of the first sub-pixel and the third sub-pixel which are positioned in the same layout region and adjacent to each other can be parallel to the first direction; preferably, the central connecting line of the first sub-pixel and the third sub-pixel located in the same layout region and adjacent to each other may intersect with the first direction, and in this case, the first sub-pixel and the third sub-pixel may not completely overlap in the first direction, and may partially overlap or may not overlap. By adjusting the center distance between the first sub-pixel and the third sub-pixel in the same layout region, the space utilization rate can be reasonably adjusted while a light transmission gap is formed between the adjacent repeating units.

The arrangement positions of the sub-pixels are reasonably planned, so that the space utilization rate is optimized, and the pixel arrangement density is improved.
Taking the orientation shown in fig. 5 as an example, in one repeating unit 110, the red sub-pixels and the blue sub-pixels are arranged at intervals along the Y direction, and a connecting line of centers of the red sub-pixels and a center of the blue sub-pixel forms a first diagonal line 121 of the first virtual quadrangle 120, and the two green sub-pixels may be respectively located at two sides of the first diagonal line 121, wherein a connecting line of centers of the two green sub-pixels may be perpendicular to the Y direction or not, as long as the connecting line of centers of the red sub-pixels, the blue sub-pixels and the green sub-pixels forms a quadrangle.
Preferably, the center line of the two green sub-pixels is perpendicular to the Y-direction, and the two green sub-pixels are symmetrical with respect to the first diagonal line 121.
Further, in the present embodiment, the repeating units 110 in the odd rows and the repeating units 110 in the even rows are arranged in a staggered manner, so that the repeating units 110 in the odd rows are aligned in the column direction, and the repeating units 110 in the even rows are aligned in the column direction, so that the arrangement of the repeating units 110 in the pixel structure is more compact, more repeating units 110 can be arranged in a unit area, the density of the repeating units 110 in the pixel structure is increased, and the resolution of the display panel is improved.
In this embodiment, the pixel structure includes a plurality of rows of repeating unit groups, each row of repeating unit group including a plurality of repeating units arranged in the same row along the second direction; the repeating units in the two adjacent rows of repeating unit groups are arranged in a staggered manner, and the adjacent second sub-pixels in the two adjacent repeating units are positioned in the same row; preferably, the central connecting line of the second sub-pixels located in the same column is parallel to the second direction.
In some embodiments, as shown in fig. 6, the pixel structure includes five repeating unit groups 100, which are respectively defined as a first repeating unit group m1, a second repeating unit group m2 …, a fifth repeating unit group m5 along the second direction, and each repeating unit group 100 includes a plurality of repeating units 110 spaced along the first direction, and in any two adjacent repeating unit groups 100, the repeating units 110 in one repeating unit group 100 are arranged offset from the repeating units 110 in the repeating unit group 100 in another row.
In other words, any one of the repeating units 110 in the second column repeating unit group m2 is located between two adjacent repeating units 110 in the first column repeating unit group m 1. The repeating units 110 in the first repeating unit group, the repeating units 110 in the third repeating unit group and the repeating units 110 in the fifth repeating unit group are aligned in the row direction, and the repeating units 110 in the second repeating unit group and the repeating units 110 in the fourth repeating unit group are aligned in the row direction, so that the arrangement of the repeating units 110 is more compact, more repeating units 110 can be arranged in a unit area, the density of the repeating units 110 is increased, and the resolution of the display panel is improved.
In addition, the second direction is parallel to the central connection line direction of the first sub-pixel 111 and the third sub-pixel 113 in the repeating unit 110, that is, as shown in fig. 6, the first sub-pixel 111 and the third sub-pixel 113 are spaced apart in the column direction, and then the second direction is the column direction, that is, the Y direction in fig. 1.
Taking the pixel structure shown in fig. 6 as an example, along the second direction, the centers of the first sub-pixel 111 and the third sub-pixel 113 in the same column are located on the same straight line. Meanwhile, along the second direction, the centers of the second sub-pixels 112 in the same column are located on the same straight line. With continued reference to fig. 5, in each repeating unit 110, a line connecting the center of any one of the second sub-pixels 112, the center of the first sub-pixel 111, and the center of the third sub-pixel 113 forms a triangle, and an internal angle of the triangle where the second sub-pixel 112 is located is an acute angle. It is understood that, along the first direction, any one of the second sub-pixels may refer to the left second sub-pixel, and may also refer to the right second sub-pixel. In the embodiment of the present invention, the inner angle of the second sub-pixel 112 is designed to be an acute angle, which can reduce the distance between the first sub-pixel 111 and the third sub-pixel 113, and improve the tightness of the repeating unit 110, thereby improving the resolution of the display panel and ensuring the display effect of the display panel.
In some embodiments, the central connecting lines of any four adjacent second sub-pixels 112 form a second virtual quadrangle 130, and the angle of the smallest internal angle of the second virtual quadrangle 130 is greater than 60 °.
In the second direction, in the two adjacent rows of repeating unit groups 100, a second virtual quadrangle 130 is formed by connecting the centers of two adjacent green sub-pixels in one row of repeating unit group 100 with the centers of two adjacent green sub-pixels in the other row of repeating unit group 100, that is, a second virtual quadrangle 130 is formed by connecting the centers of four adjacent green sub-pixels, and the sub-pixel at the center of the second virtual quadrangle 130 may be a red sub-pixel or a blue sub-pixel. Through the design, the arrangement of the repeating units can be more uniform, and the display effect of the display panel is ensured.
If the distance between the adjacent green sub-pixels is too small, when one of the green sub-pixels is lit, the adjacent green sub-pixels may be lit, and the display effect of the display panel is affected, therefore, the angle of the minimum inner angle of the second virtual quadrangle 130 is greater than or equal to 60 ° in the embodiment of the present invention, so that the distance between the adjacent green sub-pixels can be increased, and the display effect of the display panel is ensured. Wherein the smallest interior angle is the angle α in fig. 6.
In some embodiments, a central connecting line of two first subpixels 111 and two third subpixels 113 adjacent to one second subpixel 112 forms a third virtual quadrangle 140, the third virtual quadrangle 140 is a trapezoid, a length of a first side 141 in the third virtual quadrangle 140 is greater than a length of a second side 142, and as shown in fig. 1, the first side 141 may be a central connecting line of a blue subpixel and a central connecting line of a red subpixel of two adjacent repeating units in the second column repeating unit group; the second side may be a connecting line of the red sub-pixel and the blue sub-pixel in one repeating unit of the first column repeating unit group, and one repeating unit of the first column repeating unit group is located on a middle dividing line of two repeating units of the second column repeating unit group.
By making the length of the first side 141 greater than the length of the second side 142, the distance between the repeating units in the repeating unit group can be made to just accommodate the repeating units in the adjacent columns, so that the compactness of the arrangement of the repeating units in the pixel structure is improved, and the resolution of the display panel is further improved.
Preferably, the third virtual quadrangle 140 is an isosceles trapezoid. The first side 141 is the lower base of the isosceles trapezoid, and the second side 142 is the upper base of the isosceles trapezoid. When the third virtual quadrangle 140 is an isosceles trapezoid, the arrangement of the repeating units 110 is more uniform, and the display effect of the display panel is ensured.
As shown in fig. 7, in the three consecutive columns of repeating unit group 100, the connection of the centers of two adjacent repeating units 110 in the first column of repeating unit group and the centers of two adjacent repeating units in the third column of repeating unit group forms a fourth virtual quadrangle 150, and the center of the fourth virtual quadrangle 150 coincides with the center of the first virtual quadrangle 120 corresponding to one repeating unit 110 in the second column of repeating unit group and located within the fourth virtual quadrangle 150.
Hereinafter, for convenience of description, the green sub-pixel positioned at the left side may be referred to as a first green sub-pixel, and the green sub-pixel positioned at the right side may be referred to as a second green sub-pixel.
The first green sub-pixel, the red sub-pixel and the blue sub-pixel form one pixel, and the red sub-pixel, the blue sub-pixel and the second green sub-pixel form the other pixel, so that two adjacent pixels share one red sub-pixel and one blue sub-pixel.
In the fabrication process of the pixel structure, the light-emitting material is usually deposited on the substrate by using an opening of a Fine Metal Mask (FMM) to form each sub-pixel.
In order to simplify the manufacturing process of the pixel structure, the manufacturing efficiency of the pixel structure is improved, and the manufacturing cost of the display panel is reduced. In the embodiment, the structures and the sizes of the first sub-pixel 111 and the third sub-pixel 113 in each repeating unit are the same, and the structures and the sizes of the two second sub-pixels 112 are the same, so that the first sub-pixel 111 and the third sub-pixel 113 can share an opening of one mask plate, and the two second sub-pixels 112 can share the other mask plate.
Preferably, all red sub-pixels, all green sub-pixels and all blue sub-pixels share the same mask, i.e., three color sub-pixels can be formed using the same mask. When all the red sub-pixels, all the green sub-pixels and all the blue sub-pixels are formed by using the same mask plate, after all the red sub-pixels are formed on the substrate by evaporation by using one mask plate, the mask plate is moved, alignment is carried out by using evaporation equipment, all the green sub-pixels are formed on the substrate by evaporation by using the mask plate, and finally all the blue sub-pixels are formed on the substrate by evaporation by using the mask plate.
Therefore, the same mask plate can be used for preparing the sub-pixels with three different colors, the number of dies used for manufacturing the mask plate is reduced, the manufacturing process of the pixel structure can be simplified, the manufacturing efficiency of the pixel structure is improved, and the manufacturing cost of the display panel is reduced.
When the first sub-pixel 111 and the third sub-pixel 113 share one mask plate opening, in the same repeating unit group, two adjacent green sub-pixels in two adjacent repeating units 110 share the same mask plate to form, as shown in fig. 8, so that the aperture opening ratio of the mask plate for manufacturing the two adjacent green sub-pixels is increased, and further, the stability of the green sub-pixels prepared by using the mask plate is better, and the service life of the green sub-pixels can be prolonged.
For another example, when all the red subpixels and all the blue subpixels share one mask plate, and in the same column, two adjacent green subpixels in two adjacent repeating units share the same mask plate to form, so that the aperture opening ratio of the mask plate for manufacturing the two adjacent green subpixels is increased, and further, the stability of the green subpixels prepared by using the mask plate is better, and the service life of the green subpixels can be prolonged.
It should be noted that the red sub-pixel has a shape of the light emitting region of the red sub-pixel, that is, when the opening of the mask has a quadrilateral shape, a quadrilateral light emitting layer is formed on the substrate during evaporation, and then the anode layer or the pixel defining layer is formed on the light emitting layer to determine the shape of the light emitting region of the red sub-pixel. Accordingly, the meaning of the shape of the blue sub-pixel and the green sub-pixel is identical to the meaning of the shape of the red sub-pixel, and thus, the description thereof is omitted.
Preferably, along the second direction, the centers of the second sub-pixels in the same row are in the same line, so that two second sub-pixels can be prepared by using one opening of the mask plate, the number of dies for manufacturing the mask plate is reduced, the preparation process of the pixel structure is simplified, and the manufacturing cost of the display panel is reduced.
In any two adjacent repeating units 110 in the repeating unit group 100, the distance between two red sub-pixels, the distance between two blue sub-pixels, and the distance between two green sub-pixels are the same, so that on one hand, the arrangement of the sub-pixels in the pixel structure is tighter, the arrangement uniformity of the repeating units 110 is ensured, and the display effect of the display panel can be improved while the resolution of the display panel is improved. On the other hand, one mask plate can be used for sequentially evaporating all the red sub-pixels, the blue sub-pixels and the green sub-pixels, so that the preparation process of the mask plate can be simplified, the manufacturing efficiency of the pixel structure is improved, and the manufacturing cost of the display panel is reduced.
A second aspect of the embodiments of the present invention provides a display panel, which includes the pixel structure described above, wherein the display panel may be applied to a tablet computer, a smart phone, and other mobile terminals or other terminal devices.
On one hand, the pixel structure provided by the embodiment of the invention can simplify the preparation process of the mask plate by enabling at least two different colors of sub-pixels in all red sub-pixels, all green sub-pixels and all blue sub-pixels to share the same mask plate, thereby improving the manufacturing efficiency of the pixel structure and reducing the cost of the display panel.
On the other hand, the pixel structure is provided with the reticular light-transmitting gap 200, so that light rays enter the lower part of the display panel through the light-transmitting gap, the transmittance of the display panel is improved, and the normal work of the camera under the screen and the fingerprint identification device under the screen is further ensured.
