Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
As mentioned in the background art, the conventional OLED display panel is prone to color mixing during manufacturing, and the inventors have studied to find that the reason for this problem is: OLED display panel need use the coating by vaporization technology usually when the preparation, need use high accuracy metal mask version FMM during the coating by vaporization, along with display panel resolution ratio and the continuous promotion of screen body size, FMM opens the degree of difficulty of net and more big, and the deformation that produces when opening the net can directly influence the coating by vaporization effect, leads to display panel to appear the colour mixture.
In view of the above problem, the present embodiment provides a display panel, and fig. 1 is a schematic diagram of the display panel provided in the present embodiment, and with reference to fig. 1, the display panel includes:
a plurality of pixel units 10 arranged in an array, each pixel unit 10 including at least three sub-pixel units 11 of different light emission colors;
each sub-pixel unit 11 has a first side 111 and a second side 112 opposite to each other along the first direction X, the first side 111 includes a first sub-side 21 and a second sub-side 22, the first sub-side 21 and the second sub-side 22 form a first corner a, the second side 112 includes a third sub-side 23 and a fourth sub-side 24, the third sub-side 23 and the fourth sub-side 24 form a second corner B, the first corner a is convex in a direction away from the center of the sub-pixel unit 11, and the second corner B is concave in a direction adjacent to the center of the sub-pixel unit 11.
When the display panel is manufactured, a mask having a plurality of pixel openings is generally used for evaporation, and a corresponding film layer of each sub-pixel unit is evaporated onto a substrate, where the pixel openings of the mask have the same shape as the sub-pixels. The first direction X may be a row direction or a column direction of the display panel, the first direction X is a direction perpendicular to a stretching direction of the mask, and the stretching direction of the mask is, for example, the second direction Y in the drawing.
Since the first edge 111 and the second edge 112 are opposite to each other along the first direction X, the first corner a and the second corner B are opposite to each other along the first direction X, and when the display panel is manufactured, the mask is stretched along a direction perpendicular to the first direction X, and the mask is retracted along a non-stretching direction (the first direction X). When the mask is stretched, the edges corresponding to the first sub-edge 21, the second sub-edge 22, the third sub-edge 23 and the fourth sub-edge 24 in the pixel opening can guide the force applied to the pixel opening, the stretching force can lead the direction change of the increase of the angular angle on the pixel opening corresponding to the first corner A and the second corner B to change, the corners corresponding to the first corner A and the second corner B on the pixel opening can guide the retraction to a certain extent, the mask is prevented from being folded when being stretched, the position of the pixel opening is changed, the position of an evaporation sub-pixel unit is changed, and color mixing is caused with other sub-pixel units. In addition, since the first corner a protrudes outward in a direction away from the center of the sub-pixel unit 11, and the second corner B protrudes inward in a direction adjacent to the center of the sub-pixel unit 11, when the pixel opening is stretched, the vertex of the corner corresponding to the first corner a in the pixel opening tends to move in a direction adjacent to the center of the pixel opening, and the vertex of the corner corresponding to the second corner B in the pixel opening tends to move in a direction away from the center of the pixel opening, which cancel each other out, so that the change of the shape and position of the pixel opening can be reduced, and the occurrence of color mixing can be further avoided.
It should be noted that fig. 1 only exemplarily shows that one pixel unit 10 includes four sub-pixel units 11, and the present invention is not limited thereto, and in other embodiments, one pixel unit 10 may further include three sub-pixel units 11 or more than four sub-pixel units 11.
Alternatively, along the first direction X, the adjacent sub-pixel units 11 are symmetrical with respect to a line perpendicular to the first direction X.
Specifically, the first imaginary line 20 is perpendicular to the first direction X in fig. 1, and the sub-pixel units 11 on both sides of the first imaginary line 20 are symmetrical with respect to the first imaginary line 20. Through setting up along the sub-pixel unit 11 that first direction X is adjacent for the straight line symmetry that is perpendicular with first direction X, make to have great space (as shown by dotted line diamond frame in FIG. 1) between the adjacent sub-pixel 11 when not changing display panel's resolution ratio to make display panel can have great printing opacity district, make things convenient for optical sensor settings such as camera or parallel fingerprint identification sensor under the screen. For example, a larger space between adjacent sub-pixels 11 may be set without an opaque structure such as a metal trace, so that the larger space is a transparent region.
Alternatively, referring to fig. 1, each pixel unit 10 includes a first sub-pixel unit 101, a second sub-pixel unit 102, and two third sub-pixel units 103; the connecting line of the geometric centers of the first sub-pixel unit 101, the second sub-pixel unit 102 and the two third sub-pixel units 103 is a quadrangle, and the first sub-pixel unit 101 and the second sub-pixel unit 102 are located on a diagonal line of the quadrangle.
With this arrangement, the connecting line between adjacent sub-pixel units 11 of the same color is a straight line or a diagonal line, so that the jaggy feeling can be minimized when the diagonal line or the curved line is displayed. Illustratively, when the diagonal line of the quadrangle forms an angle of 45 degrees with the first direction X, the connecting line of the adjacent sub-pixel units 11 of the same color is a straight line or a 45-degree oblique line.
Fig. 2 is a schematic diagram of another display panel according to an embodiment of the present invention, and optionally, referring to fig. 2, the first angle a and the second angle B of two adjacent sub-pixel units 11 along the second direction Y are different in position along the first direction X, where the first direction X and the second direction Y intersect with each other.
By the arrangement, the first sub-pixel 101 and the second sub-pixel 102 have the same shape and arrangement relationship, and the first sub-pixel unit 101 and the second sub-pixel unit 102 can be manufactured by using the same mask, so that the mold opening cost is saved.
Alternatively, the first angle a and the second angle B are equal in angle, and the first sub-side 21 and the second sub-side 22 are symmetrical with respect to a line parallel to the first direction X, and the third sub-side 23 and the fourth sub-side 24 are symmetrical with respect to a line parallel to the first direction X.
Specifically, in fig. 2, the second imaginary line 30 is a straight line parallel to the first direction X, the first sub-side 21 and the second sub-side 22 are symmetrical with respect to the second imaginary line 30, and the third sub-side 23 and the fourth sub-side 24 are symmetrical with respect to the second imaginary line 30. Set up first sub-limit 21 and the symmetry of second sub-limit 22 for the pixel opening is even with the limit that first sub-limit 21 and second sub-limit 22 correspond when the mask version is tensile in the mask version atress, avoids the uneven pixel opening that leads to of atress great deformation to appear, influences sub-pixel unit 11's evaporation coating effect. Set up third sub-limit 22 and the symmetry of fourth sub-limit 24 with the same reason for the pixel opening is even with the limit atress when the mask version is tensile with the limit that third sub-limit 22 and fourth sub-limit 24 correspond in the mask version, avoids the atress inequality to lead to great deformation to appear in the pixel opening, influences sub-pixel unit 11's evaporation coating effect. In addition, the first angle a is equal to the second angle B, so that when the mask is stretched, the deformation on the first edge 111 and the second edge 112 is close to each other, and the large deformation difference is avoided from affecting the evaporation effect of the sub-pixel unit 11.
Optionally, each sub-pixel unit further includes a third side 113 and a fourth side 114 parallel to each other, and the third side 111 and the fourth side 113 are parallel to the first direction X.
Specifically, the third side 113 and the third sub-side 23 form a fifth angle C, and the fourth side 114 and the fourth sub-side 24 form a sixth angle D. The first corner a, the fifth corner C and the sixth corner D in the sub-pixel unit 11 all protrude outward in a direction away from the center of the sub-pixel unit 11, and even if the position deviation of the pixel opening is large during evaporation, the position deviation of the sub-pixel unit 11 is large, due to the existence of the first corner a, the fifth corner C and the sixth corner D, an area sending color mixing between adjacent sub-pixel units 11 is a partial area of a corner, the area where the color mixing occurs is small, and the influence on the display effect is small.
It should be noted that the sizes of the first angle a, the second angle B, the fifth angle C, and the sixth angle D may be set according to the stress of the mask and the size of the space between the adjacent sub-pixel units 11, for example, the first angle a and the second angle B may be 120 degrees, and the fifth angle C and the sixth angle D may be 60 degrees.
Optionally, the first sub-pixel unit 101, the second sub-pixel unit 102, and the third sub-pixel unit 103 are a red sub-pixel unit, a green sub-pixel unit, and a blue sub-pixel unit, respectively.
Specifically, because the service life of the blue material in the blue sub-pixel unit is short, by arranging two blue sub-pixel units in one pixel unit 10, each blue sub-pixel unit can have a smaller current density under the same light emitting luminance, that is, each blue sub-pixel unit can have a smaller service life loss, thereby prolonging the service life of the blue sub-pixel unit.
Fig. 3 is a schematic diagram of a display device provided in this embodiment, and referring to fig. 3, the display device 100 includes a display panel 200 according to any embodiment of the present invention. The display device 100 may be an electronic display product such as a mobile phone and a tablet.
The embodiment further provides a mask, fig. 4 is a schematic view of the mask provided in the embodiment, and referring to fig. 4, the mask includes:
a plurality of pixel openings 40;
each pixel opening 40 has a fifth side 41 and a sixth side 42 opposite to each other along the first direction X, the fifth side includes a fifth sub-side 51 and a sixth sub-side 52, the fifth sub-side 51 and the sixth sub-side 52 form a third corner E, the sixth side 42 includes a seventh sub-side 53 and an eighth sub-side 54, the seventh sub-side 53 and the eighth sub-side 54 form a fourth corner F, the third corner E is convex in a direction away from the center of the pixel opening 40, and the fourth corner F is concave in a direction adjacent to the center of the pixel opening 40.
Specifically, since the fifth side 41 and the sixth side 42 are opposite to each other in the first direction X, the third corner E and the fourth corner F are opposite to each other in the first direction X, and when the display panel is manufactured, the mask is stretched in a direction (the second direction Y) perpendicular to the first direction X, and the mask is retracted in a non-stretching direction (the first direction X). When the mask is stretched, the fifth sub-edge 51, the sixth sub-edge 52, the seventh sub-edge 53 and the eighth sub-edge 54 in the pixel opening 40 can play a role in guiding the force applied to the pixel opening 40, the stretching force can enable the third corner E and the fourth corner F to change towards the direction of angle increase, the third corner E and the fourth corner F can play a role in guiding the retraction, wrinkles appear on the mask when stretching is avoided, the position of the pixel opening 40 is changed, the position of the evaporated sub-pixel unit is changed, and color mixing with other sub-pixel units is realized. In addition, since the third corner E protrudes outward in a direction away from the center of the pixel opening 40, and the fourth corner F is recessed in a direction adjacent to the center of the pixel opening 40, when the third corner E is stretched, the vertex of the third corner E tends to move in a direction adjacent to the center of the pixel opening 40, and the vertex of the fourth corner F tends to move in a direction away from the center of the pixel opening 40, so that the vertex of the third corner E and the vertex of the fourth corner F cancel each other out, thereby reducing the change in the shape and position of the pixel opening 40, and further avoiding the occurrence of color mixing.
Alternatively, the angles of the third corner E and the fourth corner F are equal, and the fifth sub-edge 51 and the sixth sub-edge 52 are symmetrical with respect to a line parallel to the first direction X, and the seventh sub-edge 53 and the eighth sub-edge 54 are symmetrical with respect to a line parallel to the first direction X.
The fifth sub-edge 51 and the sixth sub-edge 52 are arranged symmetrically, so that the fifth sub-edge 51 and the sixth sub-edge 52 are stressed uniformly when the mask is stretched, and the phenomenon that the pixel opening 40 is deformed greatly due to uneven stress to affect the evaporation effect of the sub-pixel units is avoided. Similarly, the seventh sub-edge 53 and the eighth sub-edge 54 are symmetrically arranged, so that the seventh sub-edge 53 and the eighth sub-edge 54 are stressed uniformly when the mask is stretched, and the phenomenon that the pixel opening 40 is deformed greatly due to uneven stress to affect the evaporation effect of the sub-pixel unit is avoided. In addition, set up third angle E and fourth angle F for when the mask drawing, the deformation on fifth side 41 and the sixth side 42 is close, avoids appearing great deformation difference, influences the coating by vaporization effect of sub-pixel unit.
Optionally, the pixel opening 40 further includes a seventh side 43 and an eighth side 44, and the seventh side 43 and the eighth side 44 are parallel to the first direction X.
Specifically, the seventh side 43 and the seventh sub-side 53 form a seventh corner G, and the eighth side 44 and the eighth sub-side 54 form an eighth corner H. The third corner E, the seventh corner G and the eighth corner H all protrude outward in a direction away from the center of the pixel opening 40, and even if the positional deviation of the pixel opening 40 is large during evaporation, the positional deviation of the sub-pixel units is large, due to the presence of the third corner E, the seventh corner G and the eighth corner H, an area for sending color mixing between adjacent sub-pixel units is a partial area of a corner, the area for generating color mixing is small, and the influence on the display effect is small.
It should be noted that the plurality of pixel openings 40 may be arranged in an array as shown in fig. 4, that is, the plurality of pixel openings 40 are sequentially arranged along the first direction X to form a plurality of pixel rows, and the plurality of pixel rows are sequentially arranged along the second direction Y. Fig. 5 is a schematic view of another mask provided in this embodiment, and referring to fig. 5, the plurality of pixel openings 40 may also be arranged in an array as shown in fig. 5, that is, the plurality of pixel openings 40 are sequentially arranged along the first direction X to form a plurality of pixel rows, the plurality of pixel rows are sequentially arranged along the second direction Y, and two adjacent pixel rows along the second direction Y are arranged in a staggered manner. Illustratively, in fig. 5, a connection line between adjacent pixel openings 40 along the second direction Y in the first pixel row and the second pixel row is at a set angle with respect to the first direction X.
The mask provided by the embodiment and the display panel provided by any embodiment of the invention belong to the same inventive concept, and have corresponding beneficial effects, and detailed technical details in the embodiment are not shown in the display panel provided by any embodiment of the invention.
