The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other embodiments that depart from these specific details, and one skilled in the art may readily use this description without departing from the spirit of the invention.
Next, the present invention is described in detail with reference to the schematic drawings, and in the detailed description of the embodiments of the present invention, the schematic drawings showing the structure of the device are not partially enlarged in general scale for convenience of description, and the schematic drawings are only examples, which should not limit the scope of the present invention. In addition, the three-dimensional dimensions of length, width and height should be included in the actual fabrication.
Fig. 1 is a schematic structural diagram of a display panel in the prior art. As shown in fig. 1, the display panel 1 includes a plurality of red sub-pixels 11, a plurality of green sub-pixels 12, and a plurality of blue sub-pixels 13, the red sub-pixels 11, the green sub-pixels 12, and the blue sub-pixels 13 are all rectangular, and every two green sub-pixels 12 are adjacently disposed, wherein the organic light emitting functional layers of the two green sub-pixels 12 are formed by using the same mask opening, so as to reduce the difficulty in manufacturing the mask. It can be understood that, in the display panel 1 with a higher pixel density, the distance between two adjacent green sub-pixels 12 is extremely small, so that the distance between the visual centers of gravity of the two green sub-pixels 12 is relatively small, which causes that human eyes cannot effectively distinguish the two green sub-pixels 12, the visual resolution of the display panel 1 is reduced, and further the display effect of the display panel 1 is affected.
For solving the above problem, this embodiment provides a novel display panel structure to increase the distance between the same-color sub-pixel vision focus of adjacent setting, guarantee that display panel's visual resolution is the same with physical resolution, and then promote display panel's display effect.
Specifically, fig. 2 is a schematic structural diagram of a display panel according to an embodiment of the present invention. As shown in fig. 2, the display panel 10 includes a plurality of pixel units 100. Fig. 3 is a schematic structural diagram of a pixel unit according to an embodiment of the present invention. As shown in fig. 3, the pixel unit 100 includes a first sub-pixel 101, two second sub-pixels 102 and a third sub-pixel 103, the two second sub-pixels 102 are arranged along the first direction Y, and the first sub-pixel 101, the second sub-pixels 102 and the third sub-pixels 103 emit light of different colors. The second sub-pixel 102 includes a dividing line L, the dividing line L penetrates through the corresponding second sub-pixel 102 along a second direction X, the second sub-pixel 102 includes at least a first sub-portion 110 located at a side of the dividing line L close to another second sub-pixel 102 in the same pixel unit 100, a width K of the first sub-portion 110 in the second direction X is smaller as it is closer to another second sub-pixel 102 in the same pixel unit 100, wherein the second direction X is perpendicular to the first direction Y. Along the first direction Y, the distance P between two second sub-pixels 102 in the same pixel unit 100 is smaller than the length of any sub-pixel.
It should be noted that, usually, the geometric center of the sub-pixel is the visual center of gravity, and the arrangement manner of the first sub-portion 110 causes the visual center of gravity of the second sub-pixel 102 to shift to a side away from another second sub-pixel 102 in the same pixel unit 100, so as to increase the distance between the visual centers of the two second sub-pixels 102 in the same pixel unit 100, so that the two second sub-pixels 102 are not confused by human eyes, and the visual resolution and the physical resolution of the display panel 10 are ensured to be the same.
It is understood that the arrangement of the first sub-portion 110 can realize the shift of the visual center of gravity of the second sub-pixel 102 no matter what proportion of the first sub-portion 110 is in the corresponding second sub-pixel 102, and therefore, the present embodiment does not specifically limit the position of the dividing line L for defining the first sub-portion 110, the shape of the second sub-pixel 102, and the width change rate of the first sub-portion 110 in the second direction X. For example, as shown in fig. 3, the first sub-portion 110 may have a trapezoid shape, and a shorter base of the trapezoid is disposed near another second sub-pixel 102 in the same pixel unit 100. Fig. 4 is a schematic structural diagram of another display panel according to an embodiment of the present invention. As shown in fig. 4, the shape of the first sub-portion 110 may also be a triangle, and a vertex of the triangle far from the dividing line L is disposed near another second sub-pixel 102 in the same pixel unit 100. In addition, although the width of the first sub-section 110 in the second direction X changes at a constant rate in fig. 3 and 4, in another embodiment of the present embodiment, the rate of change of the width of the first sub-section 110 in the second direction X may be a non-constant value, as shown in fig. 5.
With reference to fig. 2, the plurality of pixel units 100 are arranged in a plurality of pixel unit rows, the odd pixel unit rows and the even pixel unit rows are arranged in a staggered manner, and the first sub-pixel 101, the second sub-pixel 102 and the third sub-pixel 103 which are adjacently arranged in two adjacent pixel unit rows are arranged in a finished product shape.
It should be noted that, in the above arrangement manner, the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 with different emission colors are arranged more closely, which is more beneficial to color mixing of light emitted by the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103, and further improves the display effect of the display panel.
Optionally, the distance between the geometric centers of the two second sub-pixels 102 is greater than or equal to 8.7 μm.
It should be noted that the geometric center of the second sub-pixel 102 is usually the visual center of gravity of the second sub-pixel 102, and a too small distance between the visual centers of the two second sub-pixels 102 in the same pixel unit 100 may cause human eyes to be unable to effectively distinguish the two second sub-pixels 102, and the visual resolution of the display panel 10 is reduced. Experiments prove that when the distance between the visual centers of gravity of the two second sub-pixels 102 is greater than or equal to 8.7 μm, human eyes can accurately distinguish the two second sub-pixels 102 without mixing the two sub-pixels.
With continued reference to fig. 4 and 5, the two second subpixels 102 may be opposite in vertex.
It can be understood that, the arrangement mode makes the distance of the deviation of the visual gravity center of any one second sub-pixel 102 to the side away from another second sub-pixel in the same pixel unit 100 larger, the distance between the visual gravity centers of two second sub-pixels 102 in the same pixel unit 100 larger, the visual resolvability of the two second sub-pixels 102 by human eyes is higher, and the two second sub-pixels 102 are prevented from being mixed up.
Illustratively, with continued reference to fig. 4 and 5, the angle a of the opposite vertex angles of the two second sub-pixels 102 ranges from 30 ° to 180 °.
It should be noted that, in the organic light emitting display panel, the sub-pixels include a first electrode, an organic light emitting functional layer and a second electrode that are sequentially stacked along the light emitting direction thereof, wherein the organic light emitting functional layer is formed by an evaporation process, the size of the opening of the mask used in the evaporation process corresponds to the size of the organic light emitting functional layer, when the angle of the opposite vertex angle of the two second sub-pixels 102 is too small, the size of the corresponding vertex angle in the opening of the mask is smaller, the manufacturing difficulty of the mask is greater, and when the evaporation process is used to form a patterned film layer structure with a smaller vertex angle, a smaller process error can cause a greater change of the vertex angle, so that the too small angle of the opposite vertex angle of the two second sub-pixels 102 can increase the manufacturing difficulty of the display panel 10. When the angle of the opposite vertex angles of the two second sub-pixels 102 is within a range of 30 ° to 180 °, the difficulty in preparing the mask for preparing the organic light emitting functional layer in the second sub-pixels 102 is low, and the difficulty in the preparation process of the display panel 10 is low.
Fig. 6 is a schematic structural diagram of another pixel unit according to an embodiment of the present invention. As shown in fig. 6, along the first direction Y, the lengths of the first sub-pixel 101 and the third sub-pixel 103 are both a, the length of the second sub-pixel 102 is B, and the distance between two second sub-pixels 102 in the same pixel unit 100 is P, where a is 2B + P. Along the second direction X, the first sub-pixel 101 and the third sub-pixel 103 are located at two opposite sides of the two second sub-pixels 102, and the shapes of the first sub-pixel 101 and the third sub-pixel 103 are at least complementary to the shapes of the first sub-portions 110 of the two second sub-pixels 102.
In addition, the above arrangement effectively utilizes the space of the display panel 10, and increases the visual distance between the two second sub-pixels 102 in the same pixel unit 100, and reduces the area of the vacant region between the adjacent sub-pixels, thereby increasing the pixel aperture ratio of the display panel 10.
It should be noted that, in the present embodiment, the first sub-pixel 101 and the third sub-pixel 103 are only pentagonal, and the second sub-pixel 102 is triangular, which is not limited to the above description, and all cases that satisfy the above complementary shape condition are within the protection scope of the present embodiment.
In this embodiment, the shapes of the first sub-pixel 101 and the third sub-pixel 103 are necessarily complementary to the shapes of the first sub-portions 110 of the two second sub-pixels 102, and further, when the second sub-pixel 102 further includes other structures besides the first sub-portion 110, the shapes of the first sub-pixel 101 and the third sub-pixel 103 may also be complementary to some or all of the other structures, which is not limited herein.
For example, fig. 7 is a schematic structural diagram of another display panel provided in an embodiment of the present invention. As shown in fig. 7, the display panel includes a plurality of pixel units 100, in the pixel units 100, the second sub-pixel 102 may be triangular in shape, the first sub-pixel 101 and the third sub-pixel may be diamond in shape, the first sub-pixel 101 and the third sub-pixel 103 are complementary to the two second sub-pixels 102 in shape, and at this time, the first sub-pixel 101 and the third sub-pixel 103 are complementary to the first sub-portion 110 and all structures except the first sub-portion 110 of the two second sub-pixels 102.
Specifically, when the second sub-pixel 102 is triangular, the dividing line L of the second sub-pixel 102 is a straight line where the edge of the second sub-pixel 102 is far away from another second sub-pixel 102 in the same pixel unit 110, and therefore, the second sub-pixel 102 only includes the first sub-portion 110 and does not include other structures.
It should be noted that the triangle and the diamond are regular shapes with simple structure, the preparation process is simple, the process difficulty is reduced, and in the display panel 10 formed by the triangle sub-pixels and the diamond sub-pixels, the visual centers of the sub-pixels can be distributed uniformly, so that the occurrence probability of the color cast problem is effectively reduced.
On the other hand, the sides of the triangular sub-pixels and the rhombic sub-pixels extending along the oblique line direction are both one of the following two directions: the extending directions of the remaining two sides of the triangular sub-pixel except for the side on the same straight line with the dividing line L, for example, the extending directions of the first side 201 and the second side 202 in fig. 7. Therefore, the linearity of the display image of the display panel 10 is good, and the display lines are not blurred at the edges, so that the display image is clearer and the display effect is better.
Fig. 8 is a schematic sectional view along a broken line EF in fig. 7. As shown in fig. 7 and 8, each of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 includes a first electrode 301, a light-emitting functional layer 302, and a second electrode layer 303 sequentially stacked along the light-emitting direction Z thereof, and two second sub-pixels 102 adjacently disposed in the first direction Y and belonging to different pixel units 100 share the same light-emitting functional layer 302.
It should be noted that the first electrode 301 of each sub-pixel is electrically connected to a pixel circuit, and fig. 8 only illustrates the thin film transistor 400 directly connected to the corresponding first electrode 301 in the pixel circuit for simplifying the structure of the drawing.
It should be noted that the arrangement of the pixel units 100 in the display panel 10 is not limited to that shown in fig. 7, and any arrangement of the pixels having two second sub-pixels 102 whose edges are disposed opposite to each other and belong to different pixel units 100 is within the protection scope of the present embodiment.
In addition, the light-emitting functional layer 302 is shared, so that the light-emitting functional layer 302 of each of the two second sub-pixels 102 can be formed by adopting the same opening in the corresponding mask plate, and the mask plate does not need to be provided with a bridge between the openings corresponding to the two second sub-pixels 102, thereby reducing the difficulty in preparing the mask plate.
It is understood that any two adjacent sub-pixels with the same emission color may share the same organic light emitting function layer 302, and the present embodiment is not limited thereto.
Fig. 9 is a schematic structural diagram of another pixel unit according to an embodiment of the present invention. As shown in fig. 9, the second sub-pixel 102 has a diamond shape, the first sub-pixel 101 and the third sub-pixel 103 have a pentagonal shape, and the first sub-pixel 101 and the third sub-pixel 103 have shapes complementary to the shapes of the first sub-portions 110 of the two second sub-pixels 101.
It should be noted that the rhombus and the pentagon are regular patterns with simple structures, and in the first direction Y, the visual centers of gravity of the rhombus second sub-pixel 102, the pentagon first sub-pixel 101 and the pentagon third sub-pixel 103 are all located on the central line, so that in the display panel, the visual centers of gravity of the sub-pixels are distributed more uniformly, and the display effect of the display panel is better.
In this embodiment, the pixel unit may have other structures. For example, fig. 10 is a schematic structural diagram of another pixel unit provided in the embodiment of the present invention. As shown in fig. 10, the second sub-pixel 102 has a diamond shape, the first sub-pixel 101 and the third sub-pixel 103 have a heptagon shape, and the first sub-pixel 101 and the third sub-pixel 103 have a shape complementary to the two second sub-pixels 102. Fig. 11 is a schematic structural diagram of another pixel unit according to an embodiment of the present invention. As shown in fig. 11, the second sub-pixel 102 has a triangular shape, the first sub-pixel 101 and the third sub-pixel 103 have a triangular shape, and the first sub-pixel 101 and the third sub-pixel 103 are complementary to the two second sub-pixels 102.
Illustratively, the light emission colors of the first sub-pixel 101, the second sub-pixel 102 and the third sub-pixel 103 are any one of red, green and blue, respectively, and are different from each other.
Since red, green, and blue are three primary colors of light, and red, green, and blue with different intensities can be mixed to obtain light of various colors, the emission colors of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 are set to be any one of red, green, and blue, respectively, and are different from each other, so that the display colors of the display panel can be varied, and the display colors of the display panel can be enriched.
