[0043] As described in the background technology, the existing naked-eye 3D display technology still has some problems in the crosstalk between the left and right eyes. The main naked-eye 3D display technologies are mainly improved on the basis of two technologies, one is the parallax barrier technology, and the other is the cylindrical lens technology; the biggest advantage of the cylindrical lens technology over the parallax barrier technology is that its brightness will not be affected. The organic light emitting diode (OLED) display screen can solve the problems of high power consumption and slow response speed of the traditional naked-eye 3D display system. In order to effectively separate the left and right eye light to form binocular parallax, the pixels are usually arranged in a strip.

[0044] However, since the common pixel arrangement of OLED is non-strip arrangement, it is difficult to effectively separate the left and right eye light when implementing naked-eye 3D technology on OLED screens, which easily causes crosstalk between the left and right eye light.

[0045] In view of this, the present application provides a display panel and a method for preparing the same, and a display device, so as to solve the problem of left-eye and right-eye light crosstalk when an OLED screen implements naked-eye 3D technology.

[0046] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. In the following detailed description, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians of the art without making creative work are within the scope of protection of the present application. The features and exemplary embodiments of various aspects of the present application will be described in detail below.

[0047] Figure 1 is a cross-sectional structural diagram of a display panel in one embodiment of the present application, Figure 2 for Figure 1 The top view of the display panel is shown in FIG. Figure 1 and Figure 2 As shown, the display panel includes a substrate 10 , a plurality of pixel rows 20 , a first lens layer 30 and a second lens layer 40 .

[0048] Specifically, a plurality of pixel rows 20 are distributed on one side of the substrate 10, the pixel rows 20 include a plurality of pixels 21 arranged along a first direction X, the plurality of pixel rows 20 are arranged in sequence along a second direction Y, the second direction Y intersects with the first direction X, and the pixels 21 include a plurality of sub-pixels 200 of different colors. The first lens layer 30 is located on the side of the pixel row 20 away from the substrate 10, and the first lens layer 30 includes a plurality of first lenses 31. The second lens layer 40 is located on the side of the first lens layer 30 away from the substrate 10, and the second lens layer 40 includes a plurality of second lenses 41.

[0049] The orthographic projection of the first lens 31 on the substrate 10 covers the orthographic projection of a pixel 200 on the substrate 10, and the second lens 41 covers the orthographic projection of a pixel group 22 on the substrate 10, and the pixel group 22 includes a plurality of pixels 21 of the same position in at least part of the pixel rows 20 and a plurality of pixels 21 adjacent to the plurality of pixels 21 of the same position in the first direction X. The first lens 31 is used to converge the light emitted by the plurality of sub-pixels 200 in the pixel 21, and the second lens is used to separate the light emitted by adjacent pixels 21 in the same pixel row 20.

[0050] In one embodiment, the pixels 21 in the pixel row 20 include a plurality of groups of odd-numbered pixels L and even-numbered pixels R, and the odd-numbered pixels L and the even-numbered pixels R are arranged adjacent to each other. The odd-numbered pixels L are used to present an image that is intended to be output to the left eye, and the even-numbered pixels R are used to present an image that is intended to be output to the right eye.

[0051] Figure 3 Schematic diagram of the working principle of the first lens in one embodiment of the present application. Figure 3 As shown, a first lens 31 is prepared above the non-strip-arranged pixels 21 to achieve that the light of different sub-pixels 200 is gathered toward the center of the first lens 31. Since the first lens 31 is prepared on each pixel 21, the left and right eye pixel light can be effectively separated, effectively solving the crosstalk problem.

[0052] like Figure 1 As shown, a second lens 41 is prepared above the first lens 31 array to separate the light emitted by adjacent pixels 21 in the same pixel row 20. The specific principle is as follows Figure 4 As shown, Figure 4 Schematic diagram of the working principle of the second lens in one embodiment of the present application. Figure 3 and Figure 4 As shown, for a dual-view naked-eye 3D screen, each second lens 41 contains two left and right pixels L and R. Due to the light convergence effect of the first lens 31, the light crosstalk between the left and right pixels is reduced. Therefore, the distance between adjacent pixels 21 can be further reduced, thereby effectively improving the pixel density (Pixels Per Inch, PPI) of the display panel.

[0053] like Figure 1 As shown, the first lens 31 includes a first material layer 311 and a second material layer 312. The refractive index of the first material layer 311 is lower than that of the second material layer 312. The first material layer 311 includes a groove 3111 that is recessed toward the substrate 10. The second material layer 312 fills the groove 3111, and adjacent first lenses 31 share the first material layer 311.

[0054] Since the first lens 31 is recessed toward the substrate 10, for the light incident on the first lens 31, the first lens 31 is equivalent to a convex lens. According to optical common sense, a convex lens has a converging effect on incident light. Therefore, the first lens 31 can converge the light emitted from multiple sub-pixels 200 within the pixel 21.

[0055] In one embodiment, the second material layers 312 in adjacent first lenses 31 are spaced apart from each other, which can further reduce the possibility of light crosstalk.

[0056] In one embodiment, the second lens 41 includes a third material layer 411. The refractive index of the third material layer 411 is greater than or equal to that of the second material layer 312, and the surface of the third material layer 411 away from the substrate 10 bulges in a direction away from the substrate 10.

[0057] Since the second lens 41 bulges in a direction away from the substrate 10, for the light incident on the first lens 31, the second lens 41 is equivalent to a concave lens. According to optical common sense, a concave lens has a diverging effect on incident light. Therefore, the second lens 41 can separate the light emitted from adjacent pixels 21 in the same pixel row 20.

[0058] In one embodiment, the second lenses 41 adjacent to each other in the first direction X are spaced apart from each other, as specifically shown in Figure 1 and Figure 2 This setting is also for the purpose of further reducing the possibility of light crosstalk.

[0059] According to Snell's law \(n_1\sin\theta_1 = n_2\sin\theta_2\), when \(n_1 < n_2\), then \(\sin\theta_1 > \sin\theta_2\), where \(\theta_1\) is the angle of incidence of light in the film layer with refractive index \(n_1\), and \(\theta_2\) is the angle of refraction of light in the film layer with refractive index \(n_2\). The angle of incidence refers to the angle between the incident light and the normal, and the angle of refraction refers to the angle between the refracted light and the normal. Therefore, when light is incident from a film layer with a smaller refractive index to a film layer with a larger refractive index, the angle of refraction \(\theta_2\) of the light is smaller than the angle of incidence \(\theta_1\) of the light.

[0060] Therefore, by setting the refractive index of the third material layer 411 to be greater than the refractive index of the second material layer 312, according to the law of refraction, the light emitted by the pixel 21 is incident from the material with a low refractive index to the material with a high refractive index at the interface between the second material layer 312 and the third material layer 411. Therefore, total reflection will not occur, and the refraction angle of the light after refraction is smaller than the incident angle, which will cause the light to move toward the direction of the small viewing angle, thereby improving the light output efficiency of the display panel.

[0061] In one embodiment, a fourth material layer 412 is filled between adjacent second lenses in the first direction, and the refractive index of the fourth material layer 412 is less than the refractive index of the third material layer 411. Optionally, the refractive index of the fourth material layer 412 may be set equal to the refractive index of the first material layer 311.

[0062] In one embodiment, the first material layer 311 and the fourth material layer 412 may be optical adhesives with low refractive index, and the second material layer 312 and the third material layer 411 may be optical adhesives with high refractive index, for example, inorganic high refractive index particles may be added to an organic system to increase its refractive index.

[0063] In one embodiment, the display panel further includes an anode layer located between the substrate 10 and the plurality of pixel rows 20 , and a cathode layer located between the plurality of pixel rows 20 and the first lens layer 30 , both of which are conventional structures and are not indicated in the figure.

[0064] In one embodiment, the display panel further includes a thin film encapsulation layer located on the side of the second lens layer 40 away from the substrate 100, for encapsulating the plurality of pixel rows 20 to prevent water and oxygen in the external environment from corroding the plurality of pixel rows 20, thereby increasing the service life of the display panel.

[0065] In one embodiment, the pixels 21 of the same position in the pixel rows 20 are arranged linearly along the second direction Y, and the orthographic projection of the second lens 41 on the substrate 10 is a straight line. Figure 2 In this embodiment, the second lens 41 is a cylindrical lens, and the projection of the cylindrical portion on the substrate is a figure composed of straight lines, such as a square or a rectangle. Figure 2 The pixel group covered by the second lens 41 includes the plurality of pixels 21 of the same order in all pixel rows 20 and the plurality of pixels 21 adjacent to the plurality of pixels 21 of the same order in the first direction.

[0066] Figure 5 FIG. 1 is a top view of a display panel in another embodiment of the present application. Figure 5As shown, multiple pixels 21 of the same order in multiple pixel rows 20 are arranged alternately in the second direction Y, and the orthographic projection of the second lens 41 on the substrate 10 is a curved strip. In this embodiment, the projection of the columnar part of the second lens 41 on the substrate is a graph composed of curves. Figure 5 The pixel group 22 covered by the second lens 41 shown in FIG. 4 includes a plurality of pixels 21 of the same rank in all pixel rows 20 and a plurality of pixels 21 adjacent to the plurality of pixels 21 of the same rank in the first direction.

[0067] Figure 6 FIG. 1 is a top view of a display panel in another embodiment of the present application. Figure 6 As shown, the pixels 21 of the same position in the pixel rows 20 are also arranged in a staggered manner in the second direction Y. Figure 5 The difference is, Figure 6 The orthographic projection of the second lens 41 shown on the substrate 10 is a straight line.

[0068] In one embodiment, the second lenses 41 covering adjacent pixel groups 22 in the second direction are parallel to each other. Figure 5 compared to, Figure 6 The second lens 41 shown is equivalent to Figure 5 The second lens 41 is divided into a plurality of figures, such as parallelograms, whose projections on the substrate 10 are composed of straight lines. In addition, the sub-pixel arrangement has regularity, so the second lenses 41 covering adjacent pixel groups 22 in the second direction are parallel to each other.

[0069] Figure 6 The pixel group 22 covered by the second lens 41 shown in FIG. 4 includes a plurality of pixels 21 of the same rank in all pixel rows 20 and a plurality of pixels 21 adjacent to the plurality of pixels 21 of the same rank in the first direction.

[0070] Figure 7 FIG. 1 is a schematic diagram of sub-pixel arrangement of a display panel in another embodiment of the present application. Figure 7 As shown, the sub-pixel arrangement is called a "diamond" arrangement. Since the first lens 31 is a lens structure for a single pixel, it is adapted to different sub-pixel arrangements and has strong applicability. The arrangement of the multiple sub-pixels 200 of the pixel 21 of the display panel includes at least one of an RGB arrangement, a diamond arrangement, and a Delta arrangement.

[0071] The present application also provides a display device, comprising any one of the display panels described above.
