[0065] See also Figure 1 , Figure 1 A schematic diagram of a display panel 100 in an embodiment of the present application is shown. The display panel 100 provided in an embodiment of the present application includes: a substrate 110, a plurality of pixel groups 120 and a first microlens assembly 130.

[0066] In the display panel 100, a plurality of pixel groups 120 are disposed on a substrate 110, and the pixel group 120 includes a first sub-pixel 121, a second sub-pixel 122, and a plurality of third sub-pixels 123. The first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123 emit light of different colors, respectively. A first microlens assembly 130 is disposed between at least a portion of the third sub-pixels 123 and the substrate 110.

[0067] The above-mentioned display panel 100, by making the same pixel group 120 include multiple third sub-pixels 123, can increase the number of third sub-pixels 123 in the pixel group 120, increase the corresponding aperture ratio of the third sub-pixel 123 in the same pixel group 120, thereby increasing the light-emitting area of ​​the third sub-pixel 123, which is beneficial to increase the light output of blue light. By setting the first microlens assembly 130, the plasma effect between the metal electrode and other film layers of the third sub-pixel 123 can be reduced, the light output rate of blue light can be improved, and the light output of blue light can be further improved. Therefore, the present application eliminates the display disadvantages of color deviation and reduced brightness of the display caused by low blue light output, and has the effect of preventing color deviation.

[0068] Specifically, the present application achieves the effect of preventing color shift by relatively increasing the amount of blue light emitted from the display panel 100 .

[0069] See also Figure 1 and Figure 3 In one embodiment, the orthographic projection of the first microlens assembly 130 on the substrate 110 completely covers the orthographic projection of the corresponding third sub-pixel 123 on the substrate 110. Firstly, it can maximize the convergence of light, and at the same time, it can also realize the reflection of blue light to a certain extent, thereby improving the light extraction efficiency of blue light.

[0070] See also Figure 1 and Figure 3 In one embodiment, the first microlens assembly 130 includes a plurality of first lens portions 136 , the thickness of the first lens portion 136 gradually increases from the edge of the first lens portion 136 toward the center thereof, and the first lens portion 136 bulges toward the direction approaching the third sub-pixel 123 .

[0071] By the above-mentioned method, it is achieved that the first microlens assembly 130 is composed of multiple groups of first lens portions 136 with smaller structures, so that the total area of ​​the first microlens assembly 130 is larger than the area of ​​the pixel opening of the third sub-pixel 123, and it is ensured that the multiple groups of first lens portions 136 in the first microlens assembly 130 can completely cover the corresponding opening of the third sub-pixel 123. At the same time, since the process of composing the first microlens assembly 130 with multiple groups of first lens portions 136 with smaller structures includes a heat treatment process, it is easy to cause the volume or structure of the first lens portion 136 at the edge of the first microlens assembly 130 to change, so that the first microlens assembly 130 The structure of the first lens portion 136 at the edge and the first lens portion 136 in the middle of the first microlens assembly 130 is different, which affects the overall uniformity of the first microlens assembly 130. Therefore, in the present application, the area of ​​the first microlens assembly 130 is increased to make the middle of the first microlens assembly 130 relatively uniform, and multiple groups of first lens portions 136 cover the corresponding openings of the third sub-pixel 123, ensuring that the portion of the first microlens assembly 130 corresponding to the opening of the third sub-pixel 123 is relatively uniform, ensuring the enhanced uniformity of the light transmittance of the first microlens assembly 130 to the third sub-pixel 123, and playing an effect of avoiding the occurrence of optical mura.

[0072] See also Figure 1 and Figure 3 Specifically, a plurality of first lens portions 136 are arranged in a circle to form a group of first lens portions 136. Each additional group of first lens portions 136 is formed by surrounding a circle of first lens portions 136 on the periphery of the existing plurality of first lens portions 136 to form a new group of first lens portions 136. The first microlens assembly 130 is manufactured by surrounding the first lens portions 136 in multiple circles, so that the first lens portions 136 are more closely spaced.

[0073] Optionally, the first lens portion 136 is partially spherical, so that the blue light has a converging effect when emitted, thereby improving the light emission rate of the blue light.

[0074] Optionally, the angle between the spherical surface of the first lens portion 136 and the substrate 110 is 10-45°, that is, the angle between the tangent line at the contact point between the spherical surface of the first lens portion 136 and the substrate 110 and the substrate 110 is 10-45°. Exemplarily, the angle between the spherical surface of the first lens portion 136 and the substrate 110 is 30°. Thus, the convergence effect of the blue light by the first lens portion 136 can be made more uniform through the uniformly changing spherical surface, and the first lens portion 136 with angular or sudden angle changes can be prevented from causing unevenness in the blue light emission effect, thereby avoiding affecting the display effect of the display panel.

[0075] Optionally, the height of the first lens portion 136 is 0.5-1.5 um. Exemplarily, the height of the first lens portion 136 is 1 um.

[0076] Optionally, the outer diameter of the first lens portion 136 is 2-10 um. Exemplarily, the outer diameter of the first lens portion 136 is 6 um. The small height and outer diameter of the first lens portion 136 ensure that when the first lens portion 136 is added to the display panel 100, the thickness and other dimensions of the display panel 100 will not be significantly increased.

[0077] Specifically, the first sub-pixel 121 is an R pixel, the second sub-pixel 122 is a G pixel, and the third sub-pixel 123 is a B pixel.

[0079] See also Figure 1 and Figure 2 Optionally, the display panel 100 further includes a functional module 135, the functional module 135 covers the encapsulation layer 132, and the plurality of second microlens assemblies 131 are located between the functional module 135 and the encapsulation layer 132. Specifically, the functional module 135 includes a plate-shaped element with relevant functions such as a cover plate or a touch panel, which is specifically configured according to design requirements and will not be described in detail.

[0080] See also Figure 1 and Figure 2 Optionally, the display panel 100 further includes a skin structure 133 , which covers a side of the functional module 135 away from the encapsulation layer 132 , thereby enabling the display panel 100 to form a smart skin and realize a variety of electronic functions.

[0081] See also Figure 1 and Figure 2 Optionally, the display panel 100 further includes an anti-reflection layer 134, which covers the side of the epidermal structure 133 away from the encapsulation layer 132. Specifically, the anti-reflection layer 134 is an anti-reflection film, which can be set according to design requirements and will not be described in detail.

[0082] See also Figure 1 and Figure 2In one embodiment, along the thickness direction of the display panel 100, multiple second microlens assemblies 131 correspond one-to-one to multiple third sub-pixels 123, so that corresponding microlens structures are arranged on the upper and lower sides of each third sub-pixel 123, thereby improving the luminous efficiency of the third sub-pixel 123 and preventing color deviation.

[0083] See also Figure 1 and Figure 2 In one embodiment, the second microlens assembly 131 includes a plurality of groups of second lens portions, and the thickness of the second lens portion gradually increases from the edge of the second lens portion to the center thereof, and the second lens portion protrudes in a direction away from the third sub-pixel 123, thereby ensuring that the total area of ​​the plurality of groups of second lens portions is greater than the area of ​​the pixel opening of the third sub-pixel 123, and ensuring that the plurality of groups of second lens portions in the second microlens assembly 131 can completely cover the corresponding pixel opening of the third sub-pixel 123.

[0084] Specifically, the structure of the second microlens assembly 131 is similar to that of the first microlens assembly 130 , and the structure can be adjusted according to the first microlens assembly 130 , which will not be described in detail herein.

[0085] Optionally, the second lens portion is partially spherical, so that the blue light has a converging effect when emitted, thereby improving the light emission rate of the blue light.

[0086] Optionally, the angle between the spherical surface of the second lens portion and the substrate 110 is 10-45°. Exemplarily, the angle between the spherical surface of the second lens portion and the substrate 110 is 30°. Thus, the uniformly changing spherical surface can make the convergence effect of the second lens portion on the blue light more uniform, and prevent the second lens portion with angular or sudden angle changes from causing unevenness in the blue light emission effect, thereby avoiding affecting the display effect of the display panel.

[0087] Optionally, the ratio of the height to the outer diameter of the second lens portion is 0.4-0.8, so that the focusing effect of the second lens portion on blue light is controlled within a certain range. Exemplarily, the ratio of the height to the outer diameter of the second lens portion is 1:2.

[0088] Optionally, the height of the second lens portion is 1-5 um. Exemplarily, the height of the second lens portion is 3 um.

[0089] Optionally, the outer diameter of the second lens portion is 2-10 um. Exemplarily, the outer diameter of the second lens portion is 6 um. The small height and outer diameter of the second lens portion ensure that when the second lens portion is added to the display panel 100, the thickness and other dimensions of the display panel 100 will not be significantly increased.

[0090] In one embodiment, each pixel group 120 includes at least a plurality of third sub-pixels 123, and the first sub-pixel 121, the second sub-pixel 122, and at least one third sub-pixel 123 are sequentially arranged along the first direction OX. The arrangement in this embodiment is conducive to synthesizing the light of the first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123 into a light of a preset color.

[0091] Optionally, in all pixel groups 120, all first sub-pixels 121 are arranged in rows along the first direction OX, and all second sub-pixels 122 are arranged in rows along the first direction OX, thereby ensuring that the light emitted by the first sub-pixels 121 arranged along the first direction is more uniform, ensuring linearity during display.

That is, each pixel group 120 forms an RBGB arrangement structure or a GBRB arrangement structure along the first direction OX. The arrangement in this embodiment is conducive to the synthesis of the light of the first sub-pixel 121, the second sub-pixel 122 and the third sub-pixel 123 into a light of a preset color. At the same time, the third sub-pixels 123 are arranged at intervals to prevent obvious light and dark stripes from appearing during actual display due to the large area of ​​the third sub-pixels 123 and the centralized placement.

[0096] Optionally, in each pixel group 120, two third sub-pixels 123 are respectively located on both sides of the first sub-pixel 121 along the first direction OX.

The third sub-pixels 123 are arranged at intervals to prevent obvious light and dark stripes from appearing during actual display due to the third sub-pixels 123 being too large in area and being placed in a centralized manner.

[0099] In the above embodiments, two third sub-pixels 123 arranged along the first direction OX are separated by the first sub-pixel 121 or the second sub-pixel 122 to prevent obvious light and dark stripes from appearing during actual display due to the third sub-pixels 123 being too large and placed in a centralized manner.

At the same time, the third sub-pixels 123 are arranged at intervals to prevent the appearance of obvious light and dark stripes in actual display due to the third sub-pixels 123 being too large and placed in a centralized manner. In this embodiment, refer to Figure 5 and Figure 6 The third sub-pixel 123 located on either side of the first sub-pixel 121 and the second sub-pixel 122 along the second direction OY extends in the first direction OX and in the second direction OY, and the length of the third sub-pixel 123 is greater than the width.

[0103] In another embodiment, in each pixel group 120, a second sub-pixel 122, a first sub-pixel 121, and a third sub-pixel 123 are arranged in a row in sequence along the first direction OX, and another third sub-pixel 123 is arranged along the first direction OX in length and is located on either side of the first sub-pixel 121 and the second sub-pixel 122 along the second direction OY. The arrangement in this embodiment is conducive to the synthesis of the light of the first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123 into a light of a preset color. At the same time, the third sub-pixels 123 are arranged at intervals to prevent obvious light and dark stripes from appearing during actual display due to the third sub-pixels 123 being too large and placed in a centralized manner. In this embodiment, refer to Figure 7 and Figure 8 The third sub-pixel 123 located on either side of the first sub-pixel 121 and the second sub-pixel 122 along the second direction OY extends in the first direction OX and in the second direction OY, and the length of the third sub-pixel 123 is greater than the width.

[0104] Optionally, in each pixel group 120, any third sub-pixel 123 is only adjacent to the first sub-pixel 121. The third sub-pixels 123 are arranged at intervals to prevent obvious light and dark stripes from appearing during actual display due to the third sub-pixels 123 being too large and placed in a centralized manner.

[0105] Optionally, in each pixel group 120, any third sub-pixel 123 is adjacent to only the second sub-pixel 122. The third sub-pixels 123 are arranged at intervals to prevent obvious light and dark stripes from appearing during actual display due to the third sub-pixels 123 being too large and placed in a centralized manner.

[0106] Optionally, in each pixel group 120, any third sub-pixel 123 is adjacent only to the first sub-pixel 121 and the second sub-pixel 122. The third sub-pixels 123 are arranged at intervals to prevent obvious light and dark stripes from appearing during actual display due to the third sub-pixels 123 being too large and placed in a centralized manner.

[0107] Optionally, in two pixel groups 120 adjacent to each other along the first direction OX, the third sub-pixel 123 in one pixel group 120 is adjacent to the first sub-pixel 121 or the second sub-pixel 122 of the other pixel group 120. The third sub-pixels 123 are arranged at intervals to prevent obvious light and dark stripes from appearing during actual display due to the third sub-pixels 123 being too large in area and being placed in a centralized manner.

[0108] Optionally, in two pixel groups 120 adjacent to each other along the second direction OY, the third sub-pixel 123 in one pixel group 120 is adjacent to the second sub-pixel 122 and the first sub-pixel 121 of the other pixel group 120. The third sub-pixels 123 are arranged at intervals to prevent obvious light and dark stripes from appearing during actual display due to the third sub-pixels 123 being too large in area and being placed in a centralized manner.

[0109] Optionally, in all pixel groups 120, one of the third sub-pixels 123 is arranged in a row along the first direction OX and in a column along the second direction OY, and another of the third sub-pixels 123 is arranged in a column along the first direction OX and in a row along the second direction OY. This is beneficial for the light of the first sub-pixel 121, the second sub-pixel 122 and the third sub-pixel 123 to be synthesized into light of a preset color, and ensures that the light emitted by the first sub-pixel 121 arranged along the first direction is more uniform, thereby ensuring linearity during display.

[0110] It should be noted that the row may be the extension direction of the width, and the column may be the extension direction of the length, and the length is greater than the width.

[0111] In the above-mentioned various arrangements of the first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123, two third sub-pixels 123 in the same pixel group 120 are separated by the first sub-pixel 121 or the second sub-pixel 122 or by no pixel opening, so as to prevent the third sub-pixels 123 with a large area from being arranged in a concentrated manner due to the increase in the aperture ratio, thereby preventing the light and dark stripes during display. Figure 4-8 The structure in the display avoids the concentration of blue light, while pixels of the same color are arranged in rows or columns to ensure linearity during display.

[0112] Preferably, the first direction OX is perpendicular to the second direction OY.

[0113] An embodiment of the present application further provides a display device, which includes a display panel 100 .

[0114] The display panel 100 in the above-mentioned display device can increase the number of third sub-pixels 123 in the pixel group 120 by making the same pixel group 120 include multiple third sub-pixels 123, thereby increasing the corresponding aperture ratio of the third sub-pixel 123 in the same pixel group 120, thereby increasing the light-emitting area of ​​the third sub-pixel 123, which is beneficial to increase the light output of blue light. By setting the first microlens assembly 130, the light output rate of blue light can be improved, thereby further improving the light output of blue light. Therefore, the present application eliminates the display disadvantages of color deviation and reduced brightness of the display caused by low blue light output, and has the effect of preventing color deviation.
