Referring to fig. 3 and 4, fig. 3 is a schematic structural diagram of a display panel in the related art, and fig. 4 is a schematic top view of the display panel shown in fig. 3. In the related art, the pixel structure 800 includes a pixel defining layer 801 and a pixel unit 802, and the pixel defining layer 801 is located on the substrate 10. The pixel defining layer 801 includes a pixel hole 8011 penetrating the pixel defining layer 201, and the pixel unit 802 is accommodated in the pixel hole 8011 and is located on the substrate 10. Due to the limitation of the structure of the pixel aperture 8011, the light emitted by the pixel element 802 is generally perpendicular to the substrate 10, so that the area of the light emitting area of the pixel element 802 is approximately equal to the area of the pixel element 802. Taking diamond arrangement as an example, the gaps between the pixel units 802 are large, so that the brightness of the corresponding region of the gap on the display panel 100 is smaller than the brightness of the corresponding region of the pixel units 802, and the brightness uniformity of the display panel 100 is poor, which affects user experience.
Referring to fig. 5 to 7, fig. 5 is a schematic cross-sectional view of an embodiment of a display panel in the electronic device shown in fig. 2, fig. 6 is a schematic top view of the display panel shown in fig. 5, and fig. 7 is a schematic cross-sectional view of another embodiment of the display panel shown in fig. 5. The present embodiments provide a new pixel structure 20, which may include, but is not limited to, a pixel defining layer 21 and a pixel unit 22. The pixel defining layer 21 includes a pixel hole 211 penetrating through the pixel defining layer 21, and the pixel unit 22 is accommodated in the pixel hole 211 and located on the substrate 10. The area of the opening cross section of the inner surface 2111 of the pixel hole 211 parallel to the substrate 10 is gradually increased from one end of the substrate 10 to the other end, so that the area of the light emitting area of the light emitted by the pixel unit 22 is larger than the area of the pixel unit 22 after the light is reflected by the inner surface 2111 of the pixel hole 211. It can be understood that the light-emitting area of each pixel unit 22 is larger than its own area, so that the gap between the light-emitting areas of the adjacent pixel units 22 is much smaller than that of the adjacent pixel units 22, thereby making the uniformity of the brightness of the light on the display panel 100 better.
Referring to fig. 8 and 9, in one embodiment, the inner surface 2111 may have a reflective film 2112 thereon to enhance the luminescence of the inner surface 2111 (as shown in fig. 8). Specifically, the reflective film 2112 may use aluminum or silver of a certain thickness. In yet another embodiment, the material of the pixel defining layer 21 is capable of reflecting light for good reflective properties of the inner surface 2111 (as shown in FIG. 9).
Specifically, an included angle formed between the inner surface 2111 of the pixel hole 211 and the surface of the substrate 10 is smaller than or equal to a critical included angle, where the critical included angle is an included angle formed between the inner surface 2111 corresponding to the preset position Q and the surface of the substrate 10 when the light emitted from the midpoint of the pixel unit 22 is reflected by the preset position Q of the inner surface 2111 and the reflected light is perpendicular to the substrate 10.
As can be understood from fig. 5, when the included angle formed by the inner surface 2111 and the surface of the substrate 10 is equal to the critical included angle, most of the reflected light of the light emitted by the pixel unit 22 is perpendicular to the substrate 10 after being reflected by the inner surface 2111. Specifically, when the light incident to the predetermined position Q from the center of the pixel unit 22 is reflected by the predetermined position Q and then reflected by the substrate 10, the light parallel to the connection line between the center of the pixel unit 22 and the predetermined position Q or the light having a similar path to the connection line can be reflected by the inner surface 2111 and then reflected by the substrate 10, so that the light emitting area of the pixel unit 22 is substantially equal to the area of the opening cross section of the inner surface 2111 parallel to the substrate 10 and passing through the predetermined position Q, thereby reducing the light emitting area gap of the adjacent pixel unit 22.
When the included angle formed between the inner surface 2111 and the surface of the substrate 10 is greater than the critical included angle, most of the reflected light beams emitted by the pixel unit 22 are converged toward the center direction of the pixel hole 211 after being reflected by the inner surface 2111, and the light emitting area of the pixel unit 22 is smaller than or equal to the area of the pixel unit 22. Specifically, when the reflected light beam of the light beam incident to the predetermined position Q from the center of the pixel unit 22 and reflected by the predetermined position Q can converge toward the center line L of the pixel hole 211, the reflected light beam of the light beam parallel to the connection line between the center of the pixel unit 22 and the predetermined position Q or the light beam having a similar path to the connection line can converge toward the center line L of the pixel hole 211, so that the area of the light emitting area of the pixel unit 22 is smaller than the area of the opening cross section of the inner surface 2111 parallel to the substrate 10 and passing through the predetermined position Q.
Referring to fig. 7, when the included angle formed between the inner surface 2111 and the surface of the substrate 10 is smaller than the critical included angle, most of the reflected light of the light emitted by the pixel unit 22 is outwardly diffused by the central line L of the pixel hole 211 after being reflected by the inner surface 2111, and the light emitting area of the pixel unit 22 is smaller than or equal to the area of the pixel unit 22. Specifically, when the reflected light beam of the light beam incident to the preset position Q from the center of the pixel unit 22 and reflected by the preset position Q can be outwardly diffused by the center line L of the pixel hole 211, the reflected light beam of the light beam parallel to the connection line between the center of the pixel unit 22 and the preset position Q or the light beam having a similar path to the connection line can be outwardly diffused by the center line L of the pixel hole 211, so that the area of the light emitting area of the pixel unit 22 is larger than the area of the opening cross section of the inner surface 2111 parallel to the substrate 10 and passing through the preset position Q, that is, the area of the pixel unit 22, and the light emitting area gap of the adjacent pixel unit 22 can be reduced.
Specifically, the predetermined position Q may be located on a surface corresponding to between one-third and two-thirds of the thickness of the pixel defining layer 21. The radian of the pixel unit 22 is smaller than the height of the predetermined position Q on the pixel defining layer 21. Specifically, let the thickness of the pixel defining layer 21 be H and the thickness of the pixel unit 22 be D, i.e. D < H/3. Where the thickness of the pixel cell 22 is negligible D.
When the preset position Q is located at one third of the pixel defining layer 21, the thickness of the pixel unit 22 is less than one third of the thickness of the pixel defining layer 21; when the predetermined position Q is located at two-thirds of the pixel defining layer 21, the thickness of the pixel unit 22 is less than two-thirds of the thickness of the pixel defining layer 21, so that the light emitted from the pixel unit 22 through the predetermined position Q can be emitted outward perpendicular to the substrate 10 or along the center line L of the pixel hole 211.
Referring to fig. 10, fig. 10 is a schematic cross-sectional view of another embodiment of the display panel shown in fig. 5. In one embodiment, the predetermined position Q is located on the inner surface 2111 corresponding to half the thickness of the pixel defining layer 21, assuming that the pixel unit 22 is circular and has a diameter R, the edge of the pixel unit 22 is connected to the inner surface 2111, the critical included angle is α, and the included angle formed by the line connecting the center of the pixel unit 22 and the predetermined position Q and the substrate 10 is β, then:
(H/2)/[(tanα)*H/2+R]＝tanβ；
that is, β ═ α - (pi/2- α) ═ 2 α -pi/2;
in other words, tan β is cot2 α.
The inner surface 2111 forms an angle γ with the surface of the substrate board 10. It can be understood that, in the case that the thickness H of the pixel defining layer 21 is constant, the smaller γ is, the more the reflected light on the inner surface 2111 diverges outward from the center line L of the pixel hole 211 and the included angle between the reflected light and the center line L of the pixel hole 211 is, that is, the larger the light emitting area of the pixel unit 22 is, the smaller the distance between the pixel units 22 is, the better the brightness uniformity of the display panel 100 is.
Moreover, when γ is less than or equal to α and γ is not changed, the larger the thickness H of the pixel defining layer 21 is, the larger the light emitting area of the pixel units 22 is, the smaller the distance between the pixel units 22 is, and the better the brightness uniformity of the display panel 100 is.
Referring to fig. 11 to 13, fig. 11 is a schematic cross-sectional view of another embodiment of the display panel shown in fig. 5, fig. 12 is a schematic cross-sectional view of a modification of the display panel shown in fig. 11, and fig. 13 is a schematic cross-sectional view of another modification of the display panel shown in fig. 11. Optionally, the cross-sectional shape of the opening of the inner surface 2111 parallel to the substrate base plate 10 is similar to the shape of the pixel unit 22, so that the pixel unit 22 can be accommodated in the pixel hole 211, and the intensity of light incident from the pixel unit 22 to the inner surface 2111 of the pixel hole 211 is consistent.
In this embodiment, the cross-sectional shape of the inner surface 2111 parallel to the substrate base plate 10 is rectangular, and correspondingly, the pixel unit 22 is rectangular. It can be understood that, when the included angle formed by the inner surface 2111 and the surface of the substrate 10 is smaller than the critical included angle, the light emitting region of the pixel unit 22 is rectangular and the area of the light emitting region is larger than that of the pixel unit 22.
In yet another embodiment, the cross-sectional shape of the inner surface 2111 parallel to the substrate base plate 10 is circular, and correspondingly, the pixel cell 22 is rectangular. It can be understood that, when the included angle formed by the inner surface 2111 and the surface of the substrate 10 is smaller than the critical included angle, the light emitting region of the pixel unit 22 is circular and the area of the light emitting region is larger than that of the pixel unit 22. In other embodiments, the cross-sectional shape of the inner surface 2111 parallel to the substrate base plate 10 may also be a triangle, a regular hexagon, or other shapes, and is not limited herein.
Taking a rectangular pixel cell 22 as an example, the cross-sectional shape of the inner surface 2111 parallel to the substrate base plate 10 is rectangular. The center line L of the pixel hole 211 is perpendicular to the substrate and coincides with the midpoint of the pixel unit 22.
Referring to fig. 5 or 7, in one embodiment, the inner surface 2111 may include a first line 2113, and the first line 2113 is located on a plane passing through the centerline L of the pixel hole 211. The first lines 2113 are straight lines and the included angle between the first lines 2113 and the surface of the substrate base plate 10 is less than or equal to a critical included angle. It can be understood that, when the reflected light beam of the light beam incident to the preset position Q from the center of the pixel unit 22 and reflected by the preset position Q can be outwardly divergent perpendicularly to the substrate 10 or along the center line L of the pixel hole 211, the reflected light beam of the light beam parallel to the connection line between the center of the pixel unit 22 and the preset position Q or along a path similar to the connection line can be outwardly divergent perpendicularly to the substrate 10 or along the center line L of the pixel hole 211, so that the light emitting area of the pixel unit 22 is larger than the area of the pixel unit 22, and the light emitting area gap of the adjacent pixel unit 22 is reduced.
In other words, the pixel defining layer 21 may include the spacer bars 210, and adjacent pixel holes 211 are separated and surrounded by the spacer bars 210. The cross section of the isolation bar 210 in the plane of the central line L of two adjacent pixel holes 211 can be triangular or trapezoidal. Taking the isolating bar 210 with a trapezoid cross section as an example (as shown in fig. 5), two waists of the trapezoid respectively correspond to the inner surfaces 2111 of the two pixel holes 211.
Referring to fig. 11-13, in another embodiment, the inner surface 2111 may include a second line 2114, and the second line 2114 is located on the plane of the centerline L of the pixel aperture 211. The second wire 2114 includes an arc portion 2115, i.e., the second wire 2114 may be a combination of an arc and a straight line, or may be a complete arc, and is not limited herein. Wherein, the included angle between the tangent line of at least part of points on the arc portion 2115 and the substrate 10 is smaller than the critical included angle. It can be understood that, when the predetermined position Q is located on the arc portion 2115 and an included angle formed between a tangent line of the predetermined position Q and the substrate 10 is equal to a critical angle, the predetermined position Q is used as a boundary, the arc portion 2115 partially enables the reflected light to converge toward the central axis direction, and the other part diverges outward from the central axis L of the pixel hole 211, wherein an area of a light emitting area diverging outward from the central axis L of the pixel hole 211 is larger than an area of the pixel unit 22, thereby achieving a purpose of reducing a gap between light emitting areas of adjacent pixel units 22.
In a specific embodiment, the second wire 2114 has an arc shape as a whole and the inner surface 2111 is recessed toward the substrate board 10 side. When the predetermined position Q is located at the middle position of the second line 2114, an included angle between a tangent line from the predetermined position Q on the second line 2114 to the substrate 10 and the substrate 10 is smaller than a critical included angle, that is, the reflected light at the position can be outwardly diffused by the central line L of the pixel hole 211, wherein the area of the light emitting area outwardly diffused by the central line L of the pixel hole 211 is larger than that of the pixel unit 22, thereby achieving the purpose of reducing the light emitting area gap of the adjacent pixel unit 22. The included angle between the tangent lines at other positions and the substrate 10 is greater than the critical included angle, and the reflected light rays at the corresponding positions can be converged towards the central axis direction.
Referring to fig. 12, in another embodiment, the second wire 2114 has an arc shape as a whole and the inner surface 2111 protrudes away from the substrate base plate 10. When the preset position Q is located at the middle position of the second line 2114, an included angle between a tangent line from the preset position Q on the second line 2114 to the substrate base plate 10 and the substrate base plate 10 is greater than a critical included angle, and a reflected light ray at a corresponding position can be converged towards the central axis direction; the included angle between the tangent lines at other positions and the substrate 10 is smaller than the critical included angle, and the reflected light at the corresponding positions can be outwardly diffused by the central line L of the pixel hole 211, wherein the area of the light emitting area outwardly diffused by the central line L of the pixel hole 211 is larger than that of the pixel unit 22, so as to achieve the purpose of reducing the light emitting area gap of the adjacent pixel unit 22.
In another embodiment, the pixel holes 211 may include a plurality of first pixel holes (not shown), a plurality of second pixel holes (not shown), and a plurality of third pixel holes (not shown), wherein the plurality of first pixel holes, the plurality of second pixel holes, and the plurality of third pixel holes are spaced apart from each other. The pixel units 22 may include a plurality of first pixel units 22a, a plurality of second pixel units 22b, and a plurality of third pixel units 22c, wherein the first pixel units 22a are corresponding to and received in the first pixel holes, the second pixel units 22b are corresponding to and received in the second pixel holes, and the third pixels are corresponding to and received in the third pixel holes. Taking the diamond-arranged pixel structure 20 as an example, the first pixel unit 22a may be a red (R) pixel, the second pixel unit 22B may be a blue (B) pixel, and the third pixel unit 22c may be a green (G) pixel.
In yet another embodiment, based on the above embodiment, the pixel hole 211 may further include a fourth pixel hole, the pixel unit 22 may include a fourth pixel unit, and the fourth pixel unit may correspond to and be received in the fourth pixel hole. Specifically, the pixel structure 20 is an RGBW arrangement, wherein the fourth pixel is a W (white) pixel.
In the pixel structure 20 provided in the embodiment of the present application, the area of the opening cross section of the inner surface 2111 of the pixel hole 211 parallel to the substrate 10 is gradually increased from one end of the substrate 10 to the other end, so that after the light emitted by the pixel unit 22 is reflected by the inner surface 2111 of the pixel hole 211, the area of the light emitting area is larger than that of the pixel unit 22, and further, the interval between the pixel units 22 is reduced, so that the brightness uniformity of the display panel 100 is good.
