Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display panel and display device. Background Technology

[0002] With the development of display technology, glasses-free 3D display panels have become an important development direction for next-generation display terminals due to their ability to eliminate the need for auxiliary devices and provide an intuitive visual experience. Currently, glasses-free 3D display panels mostly use microlens arrays or cylindrical lens arrays as the core structure for light field control. By directionally deflecting the light emitted from pixels, the images for the left and right eyes are separated, thus presenting 3D stereoscopic imaging.

[0003] However, microlenses or cylindrical lenses typically cover pixels of different colors, and the light emitted by pixels of different colors is prone to crosstalk during propagation, affecting the visual effect of the display panel. Summary of the Invention

[0006] In some embodiments, the pixel unit includes a first pixel, a second pixel, and a third pixel arranged sequentially along a first direction and emitting different colors. The dimming structure includes a first dimming part, a second dimming part, and a third dimming part arranged sequentially along the first direction. The first dimming part, the second dimming part, and the third dimming part are respectively used to converge the light emitted by the first pixel, the second pixel, and the third pixel along the optical axis to the focal point.

[0007] In some embodiments, the top surface of the first dimming unit and the top surface of the third dimming unit are inclined surfaces, and the angle between the top surface and the bottom surface of the first dimming unit is equal to the angle between the top surface and the bottom surface of the third dimming unit.

[0008] In some embodiments, the top surface of the second dimming unit is a plane.

[0010] In some embodiments, the pixel unit includes a second pixel, a third pixel, and a first pixel located on opposite sides of the second pixel and the third pixel, wherein the first pixel, the second pixel, and the third pixel emit different colors; the dimming structure includes a first dimming part, a second dimming part, a third dimming part, and a fourth dimming part arranged sequentially along a first direction, wherein the first dimming part and the fourth dimming part are respectively disposed corresponding to the two first pixels located on opposite sides of the second pixel and the third pixel, and are used to converge the light emitted by the first pixel along the optical axis to the focal point, and the second dimming part and the third dimming part are respectively disposed corresponding to the second pixel and the third pixel, and are used to converge the light emitted by the second pixel and the third pixel along the optical axis to the focal point.

[0011] In some embodiments, the top surfaces of the first dimming unit, the second dimming unit, the third dimming unit, and the fourth dimming unit are inclined surfaces. The angle between the top surface and the bottom surface of the first dimming unit is equal to the angle between the top surface and the bottom surface of the fourth dimming unit. The angle between the top surface and the bottom surface of the second dimming unit is equal to the angle between the top surface and the bottom surface of the third dimming unit. Furthermore, the angle between the top surface and the bottom surface of the first dimming unit is greater than the angle between the top surface and the bottom surface of the second dimming unit.

[0012] In some embodiments, the first pixel in two adjacent pixel units arranged along the first direction emits different colors.

[0017] In the display panel of this application embodiment, since the dimming structure converges the light emitted by at least two pixels with different light emission colors along the optical axis to the focal point, the light received by the user's eye through the dimming structure comes from the same optical element, thereby effectively improving the problem of crosstalk caused by light emitted by pixels of different colors passing through different optical elements during propagation; and since the light emitted by at least two pixels with different light emission colors along the optical axis converges to the focal point, the light of different colors can converge to the focal point and be received by the user's eye, thus effectively avoiding the color shift problem caused by the non-overlapping focal points of different colored light.

[0018] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0022] Some embodiments of this application provide a display panel, such as Figure 1 and Figure 2 As shown, the display panel includes a substrate 10, and a pixel layer 20 and a dimming layer 30 disposed sequentially on the substrate 10 in a direction away from the substrate 10. The pixel layer 20 includes a plurality of pixel units 21, and the dimming layer 30 is located on the light-emitting side of the plurality of pixel units 21.

[0023] Each pixel unit 21 includes a plurality of pixels 210, at least some of which emit different colors. For example, each pixel unit 21 includes a first pixel 211, a second pixel 212, and a third pixel 213 that emit different colors. The dimming layer 30 includes a dimming structure 31 corresponding to the pixel unit 21, which is used to converge the light emitted along the optical axis from at least two pixels 210 of different colors in the corresponding pixel unit 21 to the focal point f.

[0024] It is worth noting that the light emitted by pixel 210 along the optical axis refers to the light that passes through the light-emitting center of pixel 210 and propagates along the thickness direction Z of the display panel 100. For example, the lens of pixel 210 on the substrate 10 can be circular, and the light-emitting center of pixel 210 on the substrate is the center of the circle. As another example, the lens of pixel 210 on the substrate 10 can be rectangular, and the light-emitting center of pixel 210 on the substrate is the geometric center of the rectangle.

[0025] In this embodiment, since the dimming structure 31 converges the light emitted along the optical axis from at least two pixels 210 of different light-emitting colors in the corresponding pixel unit 21 to the focal point f, the light received by the user's eye through the dimming structure 31 comes from the same optical element, thereby effectively improving the problem of crosstalk caused by light emitted by pixels of different colors passing through different optical elements during propagation; and since the light emitted along the optical axis from at least two pixels 210 of different light-emitting colors converges to the focal point f, the light of different colors can converge to the focal point f and be received by the user's eye, thus effectively avoiding the color shift problem caused by the non-overlapping focal points of different colored light.

[0026] In some examples, the dimming layer 30 also includes a substrate 32 on which the dimming structure 31 is disposed. The substrate 32 can elevate the dimming structure 31 so that the scattered light emitted from the pixel 210 and entering the dimming layer 30 has a certain length of path for dispersion, thereby mitigating crosstalk caused by this scattered light entering the dimming structure 31.

[0027] In some examples, the substrate 32 may be made of a material with high transmittance, such as polymethyl methacrylate, polycarbonate, polyethylene terephthalate, optical glass, optically transparent silicone, or transparent epoxy resin. Exemplarily, the refractive index of the substrate 32 may be between 1.2 and 2.2. Furthermore, the thickness of the substrate 32 may be greater than 0 and less than or equal to 100 μm.

[0028] In some examples, the dimming structure 31 may be made of materials such as polymethyl methacrylate, polycarbonate, polyethylene terephthalate, optical glass, optically transparent silicone, or transparent epoxy resin. For example, the refractive index of the dimming structure 31 may be between 1.2 and 2.2.

[0029] In some embodiments, please continue reading Figure 1 and Figure 2 The pixel unit 21 includes a first pixel 211, a second pixel 212, and a third pixel 213 arranged sequentially along the first direction X and emitting different colors. The first direction X is perpendicular to the thickness direction Z of the display panel 100. For example, the first pixel 211, the second pixel 212, and the third pixel 213 can emit red light, blue light, and green light respectively to realize the color display of the display panel 100.

[0030] The dimming structure 31 includes a first dimming unit 311, a second dimming unit 312, and a third dimming unit 313 arranged sequentially along a first direction X. The first dimming unit 311, the second dimming unit 312, and the third dimming unit 313 are respectively used to converge the light emitted by the first pixel 211, the second pixel 212, and the third pixel 213 along the optical axis to the focal point f. In other words, the first dimming unit 311 is used to converge the light emitted by the first pixel 211 along the optical axis to the focal point f, the second dimming unit 312 is used to converge the light emitted by the second pixel 212 along the optical axis to the focal point f, and the third dimming unit 313 is used to converge the light emitted by the third pixel 213 along the optical axis to the focal point f.

[0031] In this case, by modulating the light emitted from the first pixel 211, the second pixel 212, and the third pixel 213 respectively through the first dimming unit 311, the second dimming unit 312, and the third dimming unit 313, it can be effectively ensured that light of different colors converges to the same focal point after passing through their respective dimming units, thereby improving the controllability of the light field and the final display effect. In addition, the first pixel 211 to the third pixel 213 are arranged along the first direction and project light onto the same focal point with different incident positions and different incident angles. This can increase the number of viewpoints and expand the viewing angle without increasing the structural complexity.

[0032] In some embodiments, please continue reading Figure 1 and Figure 2 The top surface of the first dimming unit 311 and the top surface of the third dimming unit 313 are inclined surfaces.

[0033] Since the top surfaces of the first dimming unit 311 and the third dimming unit 313 are both inclined surfaces, the light emitted by the first pixel 211 and the third pixel 213 located on both sides of the second pixel 212 can be refracted in a directional manner, so that it converges to the focal point f.

[0034] In this embodiment, since the top surfaces of the first dimming unit 311 and the third dimming unit 313 are inclined surfaces, the position of the focus f can be controlled by adjusting the tilt angle of the top surfaces of the first dimming unit 311 and the third dimming unit 313.

[0035] like Figure 3 As shown, the angle between the top and bottom surfaces of the first dimming unit 311 is θ. The light emitted from the first pixel 211 along the optical axis is deflected and passes through the focal point f when it passes the top surface of the first dimming unit 311. The refractive index of the first dimming unit 311 is set to n1, the refractive index of the medium through which the light passes after exiting the top surface of the first dimming unit 311 is n2, and the exit angle of the light after exiting the top surface of the first dimming unit 311 is β. Therefore, the formula β = arcsin(n1sinθ / n2) can be obtained.

[0036] Furthermore, the distance F between the focal point f and the optical center of the dimming structure 31 represents the focal length. The distance D between the incident point of the light emitted by the first pixel 211 along the optical axis and the optical center when it passes the top surface of the first dimming section 311 is the optical center. The optical center of the dimming structure 31 is the intersection of the line connecting the midpoints of the top surfaces of the dimming sections located at both ends of the dimming structure 31 and the light-emitting center line that passes through the focal point f and extends along the thickness direction Z of the display panel 100. Thus, the formula for calculating the focal length F can be obtained: F / D=tan(γ). Where γ=θ-β+π / 2. In addition, the number of pixels 210 corresponding to the dimming structure 31 is N. When the width W of each pixel 210 is equal, the width of each dimming section in the dimming structure 31 is equal, and the width W of the pixel 210 is equal to the width of the dimming section, D=(N-1)W / 2.

[0037] The focal length F can be determined by the above calculation formula, and the position of the focal point f can be controlled by adjusting the tilt angle (i.e., the included angle θ) of the top surface of the first dimming unit 311.

[0038] In some embodiments, please refer to Figure 1 The angle between the top and bottom surfaces of the first dimming unit 311 is equal to the angle between the top and bottom surfaces of the third dimming unit 313. This ensures that the inclined surfaces on both sides of the second dimming unit 312 have the same tilt angle. Therefore, the light emitted by the first pixel 211 and the third pixel 213 can maintain the same deflection angle when refracted by the corresponding dimming units, thereby ensuring that the light emitted by the first pixel 211 and the third pixel 213 along their respective optical axes converges at the focal point f.

[0039] In some embodiments, please continue reading Figure 1 The top surface of the second dimming unit 312 is a plane.

[0040] In this embodiment, by setting the top surface of the second dimming unit 312 as a plane, it can be ensured that the light emitted by the second pixel 212 along the thickness direction Z of the display panel 100 can pass directly through the second dimming unit 312 without being deflected, thereby ensuring that the light emitted by the second pixel 212 has a good utilization rate.

[0041] Understandably, in the description of this application, the plane and the inclined plane are relative to a reference plane perpendicular to the thickness direction Z of the display panel 100. The plane is parallel to the reference plane, and the inclined plane has an angle with the reference plane.

[0042] In some embodiments, such as Figure 4 As shown, pixel 210 includes a light-emitting device 2101 and a collimating lens 2102 located on the light-emitting side of the light-emitting device 2101, and the dimming structure 31 is located on the side of the collimating lens 2102 away from the light-emitting device 2101.

[0043] In this case, the light emitted by the light-emitting device 2101 can be modulated using the collimating lens 2102, so that the pixel 210 ultimately emits parallel light rays. As an example, the light-emitting device 2101 is located at the focal point of the collimating lens 2102. Understandably, the light-emitting device 2101 being located at the focal point of the collimating lens 2102 means that the light-emitting center of the light-emitting device 2101 approximately coincides with or completely coincides with the focal point of the collimating lens 2102. The light-emitting center of the light-emitting device 2101 is the center of its structural outline. For example, when the light-emitting device 2101 is spherical, its center is located at the focal point of the collimating lens 2102. As another example, when the light-emitting device 2101 is cubic, its center is located at the focal point of the collimating lens 2102.

[0044] In some embodiments, the top surface of at least one of the first dimming unit 311, the second dimming unit 312, and the third dimming unit 313 is an arc surface, which is used to converge the light emitted by the corresponding pixel 210 along the thickness direction Z of the display panel 100 to the focal point f.

[0045] After the collimating lens 2102 modulates the light emitted by the light-emitting device 2101, the pixel 210 emits parallel light along the thickness direction Z of the display panel 100. By setting the top surface of at least one of the first dimming unit 311, the second dimming unit 312 and the third dimming unit 313 as an arc surface, more light emitted by the corresponding pixel 210 can be focused at the focal point f, thereby improving the display brightness.

[0046] In some embodiments, such as Figure 2 As shown, pixel unit 21 includes a second pixel 212, a third pixel 213, and a first pixel 211 located on opposite sides of the second pixel 212 and the third pixel 213. That is, one first pixel 211 is located on the side of the second pixel 212 away from the third pixel 213, and the other first pixel 211 is located on the side of the third pixel 213 away from the second pixel 212. The first pixel 211, the second pixel 212, and the third pixel 213 emit different colors.

[0047] The dimming structure 31 includes a first dimming unit 311, a second dimming unit 312, a third dimming unit 313, and a fourth dimming unit 314 arranged sequentially along the first direction X. The first dimming unit 311 and the fourth dimming unit 314 are respectively arranged corresponding to the two first pixels 211 located on opposite sides of the second pixel 212 and the third pixel 213, and are used to converge the light emitted by the first pixel 211 along the optical axis to the focal point f. The second dimming unit 312 and the third dimming unit 313 are respectively arranged corresponding to the second pixel 212 and the third pixel 213, and are used to converge the light emitted by the second pixel 212 and the third pixel 213 along the optical axis to the focal point f.

[0048] In this embodiment, the dimming structure 31 can correspond to four pixels 210, thereby effectively increasing the number of viewpoints and expanding the viewing range of the display panel 100. In addition, since one dimming structure 31 corresponds to two first pixels 211, the amount of light emitted by the color corresponding to the first pixel 211 can be effectively increased, optimizing the display effect of the display panel 100.

[0049] In some embodiments, please continue reading Figure 2 The top surfaces of the first dimming unit 311, the second dimming unit 312, the third dimming unit 313, and the fourth dimming unit 314 are inclined surfaces. The first included angle α1 between the top and bottom surfaces of the first dimming unit 311 is equal to the fourth included angle α4 between the top and bottom surfaces of the fourth dimming unit 314. The second included angle α2 between the top and bottom surfaces of the second dimming unit 312 is equal to the third included angle α3 between the top and bottom surfaces of the third dimming unit 313. Furthermore, the first included angle α1 between the top and bottom surfaces of the first dimming unit 311 is greater than the second included angle α2 between the top and bottom surfaces of the second dimming unit 312.

[0050] In this embodiment, by setting the top surface of each dimming unit as an inclined surface, the light emitted by each pixel 210 can be refracted in a directional manner, causing all the light rays to converge at the focal point f. Furthermore, since the first included angle α1 is equal to the fourth included angle α4, the top surfaces of the first dimming unit 311 and the fourth dimming unit 314 have the same tilt angle. This ensures that the light emitted by the two first pixels 211 maintains the same deflection angle when refracted by their respective dimming units, thereby ensuring that the light emitted by the two first pixels 211 along their respective optical axes converges at the focal point f. Similarly, by setting the second included angle α2 to be equal to the third included angle α3, it can be effectively ensured that the light emitted by the second pixel 212 and the third pixel 213 along their respective optical axes converges at the focal point f. Furthermore, by setting the first included angle α1 to be greater than the second included angle α2, the light emitted by each pixel 210 along its respective optical axis can converge at the focal point f after passing through the corresponding dimming unit.

[0051] In some examples, the second dimming unit 312 and the third dimming unit 313 are symmetrically arranged about their interface, and the first dimming unit 311 and the fourth dimming unit 314 are also symmetrically arranged about the interface.

[0052] It is worth noting that, for the display panel 100 described in the above embodiments, by setting each dimming unit to perform targeted light modulation on different pixels 210, the light emitted by multiple pixels 210 located in the same pixel unit 21 along the optical axis converges at the focal point f, which effectively reduces the crosstalk problem between different light rays, and the focal length can be adjusted. In addition, by using dimming units to form a dimming structure 31, and finally forming a dimming layer 30, the dimming layer 30 has high manufacturing efficiency and low manufacturing cost. For example, the dimming layer 30 can be fabricated on a large area using nanoimprint lithography. Furthermore, the master of nanoimprint lithography can be fabricated using diamond machining, laser direct writing, or electron beam exposure.

[0053] In some embodiments, the first pixel 211 in two adjacent pixel units 21 arranged along the first direction X emits the same color. In this way, a dimming structure 31 can be used to correspond to two first pixels 211 to increase the amount of light emitted by the color of the first pixel 211, thereby effectively improving the color shift problem of the display panel 100.

[0054] In some embodiments, such as Figure 5 As shown, the first pixel 211 in two adjacent pixel units 21 arranged along the first direction X emits different colors.

[0055] It is worth noting that, Figure 5 In this diagram, pixels R, G, and B represent the first pixel 211, the second pixel 212, and the third pixel 213, respectively. For example, pixel R can emit red light, pixel G can emit green light, and pixel B can emit blue light. For Figure 5 Taking the first two pixel units 21 arranged along the first direction X as an example, the first pixel 211 in the first pixel unit 21 emits red light, and the first pixel 211 in the second pixel unit 21 emits green light.

[0056] Understandably, when the first pixel 211 in two adjacent pixel units 21 emits the same color, a periodic repeating texture will be formed, which is prone to moiré patterns after being superimposed by the periodic dimming structure 31. However, in this embodiment, by setting the first pixel 211 in two adjacent pixel units 21 arranged along the first direction X to emit different colors, the first pixel 211 in adjacent pixel units 21 will alternate with different colors, thereby disrupting the regular periodicity of the single color and effectively suppressing the problem of moiré patterns. In addition, through the above setting, the pixels 210 on the substrate 10 can also be arranged in an array, and the display panel 100 can be fabricated by aligning the dimming structure 31 with the pixels 210 at different positions, which helps to reduce the manufacturing difficulty of the display panel 100.

[0057] In some embodiments, such as Figure 6 and Figure 7 As shown, the plurality of pixel units 21 include a plurality of pixel unit rows arranged along the second direction Y, and each pixel unit row includes a plurality of pixel units 21 arranged along the first direction X. A plurality of pixels 210 in each pixel unit 21 are arranged along the first direction X. Two adjacent pixel units 21 arranged along the second direction Y are staggered, and the pixels 210 arranged along the second direction Y emit the same color.

[0058] In this embodiment, by setting two adjacent pixel units 21 arranged along the second direction Y with a staggered arrangement, the periodic resonance interference condition between the pixel unit 21 and the dimming structure 31 can be broken, thereby effectively suppressing the moiré pattern problem. Furthermore, since the pixels 210 arranged along the second direction Y emit the same color, the color distribution of the display panel 100 in the second direction Y is continuous and regular, resulting in better white balance uniformity of the displayed image.

[0059] In some examples, please refer to Figure 6 Pixel units 21 arranged side-by-side along the second direction Y and spaced apart are arranged in a parallel configuration. In this case, the pixel unit 21 located between two spaced pixel units 21 is simultaneously offset from these two spaced pixel units 21. Furthermore, supplementary pixels 214 are provided in the gaps between these three pixel units 21, and the number of supplementary pixels 214 can be one or more. In the display panel 100, the supplementary pixels 214 are arranged in an array with the pixels 210 in all pixel units 21. The difference between the supplementary pixels 214 and the pixels 210 is that the light-emitting side of the supplementary pixels 214 does not have a dimming structure.

[0060] It should also be noted that for the pixel units 21 arranged side by side along the second direction Y, there may be one or more pixel units 21 spaced apart between them. Figure 6 The image only shows a one-pixel unit 21 between the two, but is not limited to this.

[0061] In some examples, please refer to Figure 7 The pixel units 21 are arranged along the second direction Y, with adjacent pixel units 21 staggered sequentially in the same direction. For example, the first pixel unit in the second row is shifted one pixel 210 to the right relative to the first pixel unit in the first row, the first pixel unit in the third row is shifted one pixel 210 to the right relative to the first pixel unit in the second row, and so on. Furthermore, supplementary pixels 214 can be provided for the areas where adjacent pixel units 21 are staggered. For example, supplementary pixels 214 and all pixels 210 in the pixel units 21 can be arranged in an array.

[0062] Understandably, Figure 6 and Figure 7The illustration shows pixel unit 21 comprising three pixels 210, but is not limited thereto. In other examples, pixel unit 21 may also comprise four or more pixels 210. For example, the four pixels 210 may be two first pixels and a second and a third pixel located between the two first pixels.

[0063] In some embodiments, such as Figure 8 and Figure 9 As shown, the dimming structure 31 includes a plurality of dimming units 310 that correspond one-to-one with a plurality of pixels 210. Two adjacent dimming units 310 are spaced apart from each other. The dimming unit 310 has a first width W1, and the pixel 210 has a second width W2, wherein 0.6×W2≤W1<W2.

[0064] In this embodiment, by setting the width of the dimming unit 310 to be smaller than the width of the pixel 210, it is beneficial to reduce the problem of moiré patterns or cutting lines appearing on the display panel due to alignment errors when the widths of the dimming unit 310 and the pixel 210 are equal. Furthermore, this also allows adjacent dimming units 310 to be spaced apart, thereby improving the problem of light crosstalk that easily occurs when adjacent dimming units 310 are connected. In addition, since the first width W1 of the dimming unit 310 is greater than or equal to 0.6 times the second width W2, it is also ensured that the dimming unit 310 has sufficient area to receive the main light from the light-emitting area of ​​the pixel 210, thus ensuring display brightness.

[0065] In some examples, the optical center of the dimming unit 310 coincides with the orthographic projection of the light-emitting center of the pixel 210 onto the substrate 10.

[0066] In some embodiments, please refer to Figure 9 The dimming layer 30 also includes a light-shielding part 33 disposed between two adjacent dimming parts 310, and the orthographic projections of the light-shielding part 33 and the dimming part 310 on the substrate 10 do not overlap.

[0067] This configuration allows the light-shielding part 33 to block the light passing between adjacent dimming parts 310, thereby preventing this light from entering the dimming part 310 and causing crosstalk. In addition, since the light-shielding part 33 is located in the gap between adjacent dimming parts 310, this space can be fully utilized, thus avoiding the problem of the light-shielding part 33 occupying extra space and causing an increase in the thickness of the display panel 100.
