[0003] As the optical field of view increases, the chief ray angle (CRA) and image height also increase, resulting in a larger offset of the light extraction unit. The light extraction unit will converge the light that has passed through the two filter units, causing the screen to experience reverse light leakage.

The orthographic projection on the plate overlaps with the orthographic projection of the corresponding filter unit on the driving back plate. The center of the light extraction unit is offset relative to the center of the corresponding filter unit along a first direction. The second polarizing layer is disposed between the color filter layer and the multiple light extraction units. The polarization direction of the second polarizing layer is orthogonal to the polarization direction of the first polarizing layer. The second polarizing layer includes multiple polarizing parts. The orthographic projection of the polarizing parts on the driving back plate overlaps with the orthographic projection of the corresponding filter unit on the driving back plate. The center of the multiple polarizing parts is offset relative to the center of the corresponding filter unit along a second direction. The second direction is opposite to the first direction.

[0007] In one embodiment of the present invention, a portion of the light passing through the filter portion passes through the light extraction unit corresponding to the filter portion, and another portion passes through the polarizing portion.

[0008] In one embodiment of the present invention, the area of ​​the polarizing portion and the pixel height of the display panel satisfy the following relationship: S = k × L; S is the area of ​​the polarizing section, L is the pixel height of the display panel, and k is the scaling factor.

[0009] In one embodiment of the present invention, the display panel has different contour lines corresponding to different pixel heights, and polarizing portions of different sizes are provided on the different contour lines. The greater the distance between the contour line and the center of the display panel, the greater the pixel height corresponding to the contour line, and the larger the area of ​​the polarizing portion on the contour line.

[0010] In one embodiment of the present invention, the distance between different positions on the contour line and the center of the display panel is always equal, and the area of ​​the polarizing portion on the same contour line is the same.

[0011] In one embodiment of the present invention, the first direction is a direction away from the center of the display panel, and the second direction is a direction close to the center of the display panel.

[0012] In one embodiment of the present invention, the polarizing part is a strip-shaped structure, and the edge of the polarizing part near the center of the display panel and the edge away from the center of the display panel are arc-shaped structures with the same curvature.

[0013] In one embodiment of the present invention, the filter units of different colors include a first filter unit, a second filter unit, and a third filter unit.

[0016] The display panel of the present invention includes a first polarizing layer and a second polarizing layer.

The center of the light extraction unit is offset relative to the center of the corresponding filter unit along a first direction, and the centers of the plurality of polarizing portions are offset relative to the center of the corresponding filter unit along a second direction. Since the second direction is opposite to the first direction, the polarizing portions are closer to the light extraction unit adjacent to the extraction unit, which can reduce or eliminate the light passing through the filter unit from entering another light extraction unit, mitigate the situation where light from two adjacent filter units simultaneously converges on the same light extraction unit, and reduce or eliminate the problem of reverse light leakage from the screen.

However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art.

[0030] Silicon-based microdisplay organic light-emitting diodes (Micro LEDs) Organic Light Emitting Diode, Micro OLEDs (Organic Light Emitting Diodes) are organic light-emitting diodes with monocrystalline silicon substrates. They have advantages such as small size, self-illumination, and high resolution, and are widely used in virtual reality and augmented reality devices. For example... Figure 1 As shown, a color filter layer 10 is fabricated on the white light-emitting material layer 6 to achieve color display of a Micro OLED microdisplay. To improve the light extraction efficiency at a positive viewing angle, a light path modulation layer 12 can also be provided on the side of the color filter layer 10 away from the driving backplate 1.

[0031] The optical path control layer 12 may include multiple light extraction units. The orthographic projections of the multiple light extraction units on the driving backplate 1 overlap with the orthographic projections of filter units of different colors on the driving backplate 1. The light extraction unit may be a microlens 121. A cover layer 122 is provided on the side of the microlens 121 away from the driving backplate 1. The cover layer 122 is located between two adjacent microlenses 121 and on the side of the microlens 121 away from the driving backplate 1. The refractive index of the cover layer 122 is greater than that of the microlens 121. When the emitted light passes through the interface between the microlens 121 and the cover layer 122, it is refracted, causing the emitted light to converge towards the center.

[0032] like Figure 2 As shown, when this display panel is used in a Micro OLED microdisplay, when performing Micro... When customizing the angle in the weak cavity architecture of an OLED microdisplay, different microlenses 121 are offset relative to their corresponding filter units at different pixel heights according to the required customized angle, in order to achieve the customized angle requirements and effects. As the chief ray angle (CRA) and pixel height increase, the required offset of the microlens 121 becomes larger. When the microlens 121 is offset to a certain extent, the orthographic projection of one microlens 121 on the driving backplate 1 overlaps with the orthographic projections of two adjacent filter units of different colors on the driving backplate 1. That is, the light passing through the two filter units will converge simultaneously to a light extraction unit, causing the screen to have a reverse light leakage problem, resulting in a reverse brightness increase in the chief ray angle, that is, the brightness decreases at the position with a higher preset brightness and the brightness increases at the position with a lower preset brightness.

[0033] Based on this, embodiments of the present invention provide a display panel. For example... Figures 3 to 7As shown, the display panel includes a first polarizing layer 14 and a second polarizing layer 15. The polarization direction of the second polarizing layer 15 is orthogonal to the polarization direction of the first polarizing layer 14. A portion of the light passing through the first polarizing layer 14 enters the light extraction unit, while at least a portion of the other light enters the polarizing portion 151 of the second polarizing layer 15 and cannot exit. The center of the light extraction unit is offset relative to the center of the corresponding filter unit along a first direction, and the centers of the plurality of polarizing portions 151 are offset relative to the center of the corresponding filter unit along a second direction. Since the second direction is opposite to the first direction, the polarizing portions 151 are closer to the light extraction unit adjacent to the extraction unit, which can reduce or eliminate the light passing through the filter unit entering another light extraction unit, alleviate the situation where the light from two adjacent filter units converges on the same light extraction unit, and reduce or eliminate the problem of reverse light leakage of the screen.

[0034] The display panel includes a first polarizing layer 14 and a second polarizing layer 15. The polarization direction of the second polarizing layer 15 is orthogonal to the polarization direction of the first polarizing layer 14. A portion of the light passing through the first polarizing layer 14 enters the light extraction unit, while at least a portion of the other light enters the polarizing portion 151 of the second polarizing layer 15 and cannot exit. The center of the light extraction unit is offset relative to the center of the corresponding filter unit along a first direction, and the centers of the plurality of polarizing portions 151 are offset relative to the center of the corresponding filter unit along a second direction. Since the second direction is opposite to the first direction, the polarizing portions 151 are closer to the light extraction unit adjacent to the extraction unit, which can reduce or eliminate the light passing through the filter unit entering another light extraction unit, mitigate the situation where the light from two adjacent filter units converges on the same light extraction unit, and reduce or eliminate the problem of reverse light leakage of the screen.

[0035] The display panel involved in the embodiments of the present invention will be described in detail below with reference to specific examples.

[0036] like Figure 3 and Figure 4 As shown, the display panel may include a driving backplate 1, a pixel defining layer 2, an anti-corrosion layer 3, and multiple filling portions 4. The pixel defining layer 2 is disposed on the driving side of the driving backplate 1 and has multiple first openings 21. A pixel defining portion 22 is formed between two adjacent first openings 21. Pixel electrodes are typically disposed on the side of the pixel defining portion 22 away from the driving backplate 1. To prevent corrosion of the pixel electrodes, an anti-corrosion layer 3 is provided on the side of the pixel electrodes away from the driving backplate 1 before subsequent processes. The anti-corrosion layer 3 covers the pixel defining portion 22 and the portion of the driving backplate 1 exposed at the bottom of the first opening 21. The anti-corrosion layer 3 forms a recess within the first opening 21. Multiple filling portions 4 fill different recesses, and the side of the filling portion 4 away from the driving backplate 1 is substantially flush with the side of the anti-corrosion layer 3 away from the driving backplate 1.

[0037] The display panel may further include multiple partition structures 5 and a light-emitting material layer 6. The partition structures 5 are located on the side of the filling portion 4 away from the driving backplate 1, forming pixel openings between adjacent partition structures 5. Each partition structure 5 has a partition groove 53. The partition structure 5 includes a first partition layer 51 and a second partition layer 52, with the second partition layer 52 located on the side of the first partition layer 51 away from the driving backplate 1. The partition groove 53 includes a first groove segment 531 and a second groove segment 532. The first groove segment 531 is a recess on the first partition layer 51, and the second groove segment 532 is an opening on the second partition layer 52. The second groove segment 532 is interconnected with the first groove segment 531, and the width of the second groove segment 532 is smaller than the width of the first groove segment 531. The light-emitting material layer 6 is located on the side of the anti-corrosion layer 3 and the partition structures 5 away from the driving backplate 1, filling the pixel openings and the partition grooves 53. The display panel may also include a common electrode 7, which is located on the side of the light-emitting material layer 6 away from the driving backplate 1.

[0038] The display panel may further include an encapsulation layer 8, which is disposed on the side of the common electrode 7 away from the driving backplate 1, thereby encapsulating the common electrode 7 and preventing water and oxygen corrosion. The encapsulation layer 8 may be a single-layer or multi-layer structure, and the material of the encapsulation layer 8 may include organic or inorganic materials, without special limitation. The display panel may further include a first planarization layer 9, a color filter layer 10, a second planarization layer 11, an optical path control layer 12, and a cover plate 13. The first planarization layer 9 is disposed on the side of the encapsulation layer 8 away from the driving backplate 1, the color filter layer 10 is disposed on the side of the first planarization layer 9 away from the driving backplate 1, the second planarization layer 11 is disposed on the side of the color filter layer 10 away from the driving backplate 1, the optical path control layer 12 is disposed on the side of the second planarization layer 11 away from the driving backplate 1, and the cover plate 13 is disposed on the side of the optical path control layer 12 away from the driving backplate 1.

[0039] The color filter layer 10 includes filter units of different colors. These filter units may include a first filter unit 101, a second filter unit 102, and a third filter unit 103. The first filter unit 101 may be red, the second filter unit 102 may be green, and the third filter unit 103 may be blue. The filter units of different colors are arranged in multiple columns. In adjacent columns, the first filter unit 101 in one column is located between the second filter unit 102 and the third filter unit 103 in the other column; the second filter unit 102 in one column is located between the third filter unit 103 and the first filter unit 101 in the other column; and the third filter unit 103 in one column is located between the first filter unit 101 and the second filter unit 102 in the other column.

[0040] The optical path control layer 12 may include multiple light extraction units. The orthographic projections of the multiple light extraction units on the driving backplate 1 overlap with the orthographic projections of filter units of different colors on the driving backplate 1. Each light extraction unit may be a microlens 121. A cover layer 122 is provided on the side of the microlens 121 away from the driving backplate 1. The cover layer 122 is located between two adjacent microlenses 121 and on the side of the microlens 121 away from the driving backplate 1. The refractive index of the cover layer 122 is greater than that of the microlens 121. To achieve Micro... The angle is customized in the weak cavity architecture of OLED microdisplay, and the center of the light extraction unit is offset relative to the center of the corresponding filter unit along the first direction.

[0041] like Figure 5 As shown, the display panel also includes a first polarizing layer 14 and a second polarizing layer 15. The first polarizing layer 14 is disposed between the first planarization layer 9 and the color filter layer 10, and the second polarizing layer 15 is disposed between the second planarization layer 11 and multiple light extraction units. The polarization direction of the second polarizing layer 15 is orthogonal to the polarization direction of the first polarizing layer 14. As shown, when the light emitted from the light-emitting layer passes through the first polarizing layer 14, only light with the first polarization direction can pass through. Light with the first polarization direction cannot pass through when it is incident on the second polarizing layer with the second polarization direction. When the polarization direction of the first polarizing layer 14 is 0°, the polarization direction of the second polarizing layer 15 is 90°; when the polarization direction of the first polarizing layer 14 is 90°, the polarization direction of the second polarizing layer 15 is 0°.

[0042] When the center of the light extraction unit is offset significantly relative to the center of the corresponding filter unit along the first direction, in order to prevent light passing through the two filter units from converging simultaneously into one light extraction unit, it is necessary to prevent light passing through the filter unit from entering the non-corresponding light extraction unit without affecting the light passing through the filter unit entering the corresponding light extraction unit. Therefore, the second polarizing layer 15 is patterned. The second polarizing layer 15 includes multiple polarizing portions 151. The orthographic projection of the polarizing portion 151 on the driving backplate 1 overlaps with the orthographic projection of the corresponding filter unit on the driving backplate 1. The centers of the multiple polarizing portions 151 are offset relative to the center of the corresponding filter unit along a second direction, which is opposite to the first direction.

[0043] Since the second direction is opposite to the first direction, the polarizing section 151 is closer to the light extraction unit adjacent to the extraction unit. Part of the light passing through the filter unit enters the light extraction unit corresponding to the filter unit, and the other part enters the polarizing section 151. The light entering the polarizing section 151 cannot be emitted, thus preventing the light passing through the filter unit from entering another light extraction unit that does not correspond to it. This reduces the situation where the light from two adjacent filter units converges on the same light extraction unit at the same time, thereby reducing or eliminating the problem of reverse light leakage of the screen.

[0044] The area of ​​the polarizing section 151 and the pixel height of the display panel satisfy the following relationship: S = k × L; where S is the area of ​​the polarizing section 151, L is the pixel height of the display panel, and k is a scaling factor. Generally, a larger pixel height requires a larger principal ray angle, and a larger pixel height or a larger principal ray angle necessitates a larger offset of the microlens 121. With a larger offset, the area of ​​the polarizing section 151 also needs to be increased accordingly.

[0045] like Figure 6 As shown, the display panel has different contour lines corresponding to different pixel heights. Different contour lines are provided with polarizing portions 151 of different sizes. The polarizing portions 151 are strip-shaped, with the edges of the polarizing portions 151 having the same curvature at their edges near and away from the center of the display panel. The greater the distance between the contour line and the center of the display panel, the greater the pixel height corresponding to the contour line, and the larger the area of ​​the polarizing portions 151 on the contour line. The distance between different positions on the contour line and the center of the display panel is always equal, and the area of ​​the polarizing portions 151 on the same contour line is the same. The polarizing portions 151 are offset towards the center of the display panel; therefore, the first direction is away from the center of the display panel, and the second direction is opposite to the first direction; therefore, the second direction is towards the center of the display panel.

[0046] like Figure 7 As shown, Figure 1 When the distance between the center of the display panel and the contour lines of different dimensions is 14mm, 12mm, 10mm, 8mm, 6mm, 4mm, 2mm and 0mm respectively, the curves showing the relationship between the light emission angle and the brightness attenuation are L1, L2, L3, L4, L5, L6, L7 and L8 respectively. Figure 3 In the curve L1 corresponding to the larger principal ray angle, it can be seen that the brightness attenuation is greater in the direction H1 of the non-principal ray angle, while the brightness attenuation is smaller in the direction H2 of the principal ray angle. Therefore, when the principal ray angle is large, the display panel can reduce or eliminate the problem of reverse light leakage of the screen while achieving a constant angle.
