[0052] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0053] Figure 1 FIG. 1 is a schematic diagram of a structure of a display panel according to an embodiment of the present invention. Figure 1 As shown, this embodiment provides a display panel, including a substrate 10, a plurality of display units 20 located on one side of the substrate 10, and an encapsulation layer 30, wherein the encapsulation layer 30 is arranged on a side of the display unit 20 away from the substrate 10, and the encapsulation layer 30 includes a plurality of reflection blocks 31, and the plurality of reflection blocks 31 are arranged in a one-to-one correspondence with the plurality of display units 20, and the orthographic projection of each reflection block 31 on the substrate 10 surrounds the orthographic projection of the display unit 20 on the substrate 10, and the surface of each reflection block 31 facing away from the substrate 10 has at least two reflection sub-surfaces, and the inclination angles of the at least two reflection sub-surfaces are different, wherein the inclination angle is an acute angle formed between the reflection sub-surface and the substrate 10.

[0054] In the art, the light emitted by the display unit is usually emitted in all directions, resulting in total reflection of the large-angle light at the interface of the two film layers, which causes the part of the light to fail to be emitted normally, resulting in low display brightness of the display panel. If the display brightness of the display panel is increased, it is usually done by increasing the power of the display panel, which causes the power consumption of the display panel to increase, affecting the service life of the display panel. The main reason for the low display brightness of the display panel is that the light emitted by the display unit has more large-angle light, resulting in part of the light failing to be emitted straight, resulting in low light energy utilization, and thus low display brightness.

[0055] To address the above problems, this embodiment improves the structure of the encapsulation layer 30 , which includes a plurality of reflection blocks 31 , which are arranged one-to-one corresponding to a plurality of display units 20 , and the orthographic projection of each reflection block 31 on the substrate 10 surrounds the display unit 20 .

[0056] In the embodiment of the present invention, the encapsulation layer 30 includes a plurality of reflective blocks 31 arranged at intervals, and the reflective blocks 31 are used to reflect the light emitted by the display unit 20 out of the display panel to improve the utilization rate of the light emitted by the display unit 20. In addition, the plurality of reflective blocks 31 are arranged in a one-to-one correspondence with the plurality of display units 20, and the orthographic projection of each reflective block 31 on the substrate 10 surrounds the display unit 20, which can prevent the reflective block 31 from blocking the light emitted from the display unit 20 in the normal viewing direction. At the same time, the reflective block 31 reflects part of the large-angle light emitted by the display unit 20, so that the part of the large-angle light is emitted in the normal viewing direction after reflection, thereby improving the normal viewing brightness of the display panel and improving the light extraction efficiency of the display panel.

[0057] In addition, since the reflection sub-surfaces at the same angle have different reflection effects on the light emitted from the display unit 20 at different angles, and can only reflect the light within a certain angle range to the normal viewing direction, the inclination angles of at least two reflection sub-surfaces on each reflection block 31 are set to be different, so that different reflection sub-surfaces can reflect the light within different angle ranges to the normal viewing direction, further improving the light extraction efficiency of the display panel and improving the normal viewing brightness of the display panel. Please refer to Figures 1 to 7 .

[0058] It is worth noting that when light is irradiated onto the surface of the reflective block 31 facing the substrate 10, the light will be reflected in the direction of the substrate 10, and the reflective sub-surface is set on the surface of the reflective block 31 facing away from the substrate 10 to reflect the light out of the display panel, so as to improve the light extraction efficiency of the light emitted by the display unit 20.

[0059] It should be noted that the above-mentioned large-angle light refers to the range in which the angle between the light and the direction perpendicular to the substrate 10 is greater than or equal to 45°, while the normal viewing direction refers to the range in which the angle between the light and the direction perpendicular to the substrate 10 is less than or equal to 5°.

[0060] The display panel provided in this embodiment is provided with a plurality of spaced reflective blocks 31 in the encapsulation layer 30, so that each reflective block 31 reflects the large-angle light emitted by the corresponding display unit 20, so as to reflect the large-angle light emitted by the display unit 20 to the front view direction for emission, thereby improving the light emission efficiency of the display unit 20. In addition, since the light emitted by the display unit 20 is transmitted in various directions, and the orthographic projection of each reflective block 31 on the substrate 10 surrounds the orthographic projection of the display unit 20 on the substrate 10, the large-angle light emitted by the display unit 20 in multiple directions is reflected by the reflective block 31 to the front view direction, which is beneficial to improving the front view brightness of the display panel and improving the utilization rate of the light energy of the display unit 20. In addition, in order to further improve the light emission efficiency of the display unit 20, at least two reflective sub-surfaces with different inclination angles are provided on the surface of each reflective block 31 on the side away from the substrate 10, so that the light in different angle ranges is reflected by different reflective sub-surfaces to the front view direction, thereby improving the light emission efficiency of the display unit 20 and further improving the front view brightness of the display panel. The display panel in this embodiment has the characteristics of high brightness under the same power consumption and service life. At the same time, the display panel in this embodiment has lower power consumption and longer service life under the same brightness. Therefore, the display panel in this embodiment can take into account the characteristics of high brightness, low power consumption and long service life at the same time.

[0061] Based on the above embodiment, the at least two reflective sub-surfaces include a first reflective sub-surface 311 and a second reflective sub-surface 312 arranged in sequence in a direction away from the central axis of the reflective block 31, and the inclination angle of the first reflective sub-surface 311 is smaller than the inclination angle of the second reflective sub-surface 312. Figures 1 to 7 This arrangement enables the first reflective sub-surface 311 to reflect light within the first angle range to the front-view direction, while the second reflective sub-surface 312 to reflect light within the second angle range to the front-view direction, which is beneficial to improving the reflection effect of large-angle light, increasing the front-view emitted light, and thus improving the utilization rate of light energy. Among them, the maximum angle within the first angle range is smaller than the minimum angle within the second angle range.

[0062] It should be noted that the orthographic projection of each reflective block 31 on the substrate 10 surrounds the orthographic projection of the display unit 20 on the substrate 10, including at least two situations, wherein the first situation is that the orthographic projection of the reflective block 31 on the substrate 10 surrounds the orthographic projection of the display unit 20 on the substrate 10 for a circle and is connected end to end, in which case, the first reflective sub-surface 311 and the second reflective sub-surface 312 are both annular and connected end to end. The second situation is that the orthographic projection of the reflective block 31 on the substrate 10 is divided into two parts, the two parts are arranged at intervals, and each part includes the first reflective sub-surface 311 and the second reflective sub-surface 312, so as to reflect large-angle light from different directions to the front-view direction, so as to improve the front-view brightness of the display panel.

[0063] On the basis of the above-mentioned embodiment, the inclination angle of the first reflection sub-surface 311 is greater than or equal to 30° and less than or equal to 80°. If the inclination angle of the first reflection sub-surface 311 is less than 30°, many light rays cannot be reflected by the first reflection sub-surface 311, resulting in a partial waste of light energy. If the inclination angle of the first reflection sub-surface 311 is greater than 80°, the adjustable inclination angle range of the second reflection sub-surface 312 is small, which is not conducive to reflecting most of the light rays to the front view direction. Limiting the inclination angle of the first reflection sub-surface 311 within the range of 30° to 80° is conducive to adjusting the inclination angles of the first reflection sub-surface 311 and the second reflection sub-surface 312, so as to adjust the inclination angles of the first reflection sub-surface 311 and the second reflection sub-surface 312 according to the size of the display unit 20, so as to optimize the light extraction efficiency of the display unit 20.

[0064] On the basis of the above-mentioned implementation, the first reflective sub-surface 311 and the second reflective sub-surface 312 are either a plane or a convex curved surface. That is to say, the first reflective sub-surface 311 can be a plane or a convex curved surface, and it is only necessary to ensure that the first reflective sub-surface 311 can reflect the light in the normal viewing direction. Similarly, the second reflective sub-surface 312 can be a plane or a convex curved surface, and it is only necessary to ensure that the second reflective sub-surface 312 can reflect the light in the normal viewing direction. Figure 1 , Figure 3 as well as Figures 5 to 7 In the embodiment shown, the first reflective sub-surface 311 and the second reflective sub-surface 312 are convex curved surfaces. Figure 2 and Figure 4 In the illustrated embodiment, the first reflective sub-surface 311 and the second reflective sub-surface 312 are planes.

[0065] It should be noted that when the first reflective sub-surface 311 and the second reflective sub-surface 312 are convex curved surfaces, the inclination angle refers to the angle formed between the tangent line of the curved surface and the substrate 10 .

[0066] On the basis of the above embodiment, the encapsulation layer 30 includes a first encapsulation sublayer 32, the first encapsulation sublayer 32 is arranged on the side of the display unit 20 away from the substrate 10, and a plurality of reflection blocks 31 are located on the side of the first encapsulation sublayer 32 away from the substrate 10. The reflection blocks 31 are arranged on the side of the first encapsulation sublayer 32 away from the substrate 10, so that the reflection blocks 31 reflect light of a large angle to the front view direction, such as Figures 1 to 7 shown.

[0067] On the basis of the above embodiment, the first encapsulation sublayer 32 has a plurality of light emitting recesses 321, and the plurality of light emitting recesses 321 correspond to the plurality of reflective blocks 31 one by one, and each reflective block 31 contacts the side wall of each light emitting recess 321. Figures 1 to 7The reflective block 31 is arranged to contact the side wall of the light emitting concave portion 321 to prevent the reflective block 31 from blocking the light emitted from the light emitting concave portion 321 in the normal direction. Meanwhile, the reflective block 31 is arranged on the side wall to reflect the light at a large angle to the normal direction.

[0068] On the basis of the above embodiment, the encapsulation layer 30 further includes a second encapsulation sublayer 33, which is arranged on a side of the first encapsulation sublayer 32 away from the substrate 10, and a plurality of reflection blocks 31 are located between the first encapsulation sublayer 32 and the second encapsulation sublayer 33. Figure 3 , Figure 6 and Figure 7 . In addition, in order to reduce the deflection of light at the position where the first encapsulation sublayer 32 and the second encapsulation sublayer 33 contact each other and change the transmission path of the light, the difference in refractive index between the first encapsulation sublayer 32 and the second encapsulation sublayer 33 is less than or equal to 0.3, so as to ensure that the large-angle light is reflected to the front view direction through the reflection block 31. For example, the difference in refractive index between the first encapsulation sublayer 32 and the second encapsulation sublayer 33 can be 0.25. For another example, the difference in refractive index between the first encapsulation sublayer 32 and the second encapsulation sublayer 33 is 0.2. For another example, the difference in refractive index between the first encapsulation sublayer 32 and the second encapsulation sublayer 33 is 0.1.

[0069] Specifically, the first encapsulation sublayer 32 includes an inorganic material having a refractive index greater than or equal to 1.6. The first encapsulation sublayer 32 is in direct contact with the display unit 20. The use of inorganic materials can prevent the intrusion of water, oxygen, etc., thereby improving the protection effect of the display unit 20. For example, the first encapsulation sublayer 32 can be made of an inorganic material having a refractive index greater than or equal to 1.65 and less than or equal to 1.85. The second encapsulation sublayer 33 includes an organic material having a refractive index greater than or equal to 1.6. The second encapsulation sublayer 33 uses an organic material, which can planarize the surface of the first encapsulation sublayer 32 and relieve the stress of the inorganic material. The second encapsulation sublayer 33 can also include a water-absorbing material such as a desiccant to absorb water, oxygen, and other substances that invade the interior. For example, the second encapsulation sublayer 33 can be made of an organic material having a refractive index greater than or equal to 1.65 and less than or equal to 1.85.

[0070] In addition, the encapsulation layer 30 may further include a leveling sublayer 34 and a third encapsulation sublayer 35. The leveling sublayer 34 is disposed on a side of the second encapsulation sublayer 33 away from the substrate 10 to facilitate the subsequent structure to be level. The third encapsulation sublayer 35 is disposed on a side of the leveling sublayer 34 away from the substrate 10. Usually, the third encapsulation sublayer 35 is made of an inorganic material to protect the display unit 20.

[0071] On the basis of the above embodiment, the display panel further includes a pixel defining layer 40 located between the substrate 10 and the encapsulation layer 30, the pixel defining layer 40 has a plurality of pixel openings 41, each display unit 20 is correspondingly arranged in each pixel opening 41, and the orthographic projection of the reflective sub-surface on the substrate 10 overlaps with the orthographic projection of the side wall of the pixel opening 41 on the substrate 10, such as Figures 1 to 7 The orthographic projection of the reflective sub-surface on the substrate 10 overlaps with the orthographic projection of the sidewall of the pixel opening 41 on the substrate 10, which can reduce the reflective sub-surface blocking the light emitted in the front direction, so as to improve the light output rate of the display unit 20 in the front direction.

[0072] Specifically, the orthographic projection of the reflective subsurface on the substrate 10 is located inside the orthographic projection of the side wall of the pixel opening 41 on the substrate 10 to avoid the reflective subsurface blocking the light emitted in the forward direction, thereby improving the light output rate of the display unit 20 in the forward direction.

[0073] On the basis of the above-mentioned embodiment, the side wall of each pixel opening 41 includes at least two limiting sub-surfaces arranged along the central axis away from the pixel opening 41, the inclination angles of the at least two limiting sub-surfaces are different, each reflecting sub-surface corresponds to each limiting sub-surface one by one, and the orthographic projection of each reflecting sub-surface on the substrate 10 overlaps with the orthographic projection of the corresponding limiting sub-surface on the substrate 10. By providing at least two limiting sub-surfaces with different inclination angles on the side wall of the pixel opening 41, it is convenient to manufacture the reflecting sub-surface.

[0074] Specifically, after the display unit 20 is manufactured in the pixel opening 41, the first encapsulation sublayer 32 is formed on the side of the pixel defining layer 40 away from the substrate 10. Due to the influence of the pixel opening 41, the first encapsulation sublayer 32 has a light exit concave portion 321 at the position corresponding to the pixel opening 41. At the same time, the light exit concave portion 321 has the same shape as the side wall of the pixel opening 41, and a reflective block with the same shape as the pixel opening 41 is formed on the side wall of the light exit concave portion 321. At least two limiting sub-surfaces with different inclination angles are provided on the side wall surface of the pixel opening 41, so as to facilitate the manufacture of a reflective block 31 with at least two reflective sub-surfaces, and the process is simple and easy to operate.

[0075] For example, Figures 4 to 7 As shown, at least two limiting sub-surfaces include a first limiting sub-surface 411 and a second limiting sub-surface 412 arranged in sequence along a central axis direction away from the pixel opening 41, and the inclination angle of the first limiting sub-surface 411 is smaller than the inclination angle of the second limiting sub-surface 412, so as to form the first reflecting sub-surface 311 and the second reflecting sub-surface 312 mentioned above. Figure 4 As shown, the first limiting sub-surface 411 and the second limiting sub-surface 412 are planes. Figures 5 to 7As shown, the first limiting sub-surface 411 and the second limiting sub-surface 412 are convex arc surfaces.

[0076] Specifically, the orthographic projection of the first reflective subsurface 311 on the substrate 10 is located at the orthographic projection of the first limiting subsurface 411 on the substrate 10 , and the orthographic projection of the second reflective subsurface 312 on the substrate 10 is located at the orthographic projection of the second limiting subsurface 412 on the substrate 10 .

[0077] Figure 8 : is a comparison diagram of the relative brightness of the display panel in this embodiment and the existing display panel without a reflective sub-surface at different angles. Figure 8 It can be seen from the figure that the present invention effectively improves the front-view brightness of the display panel by providing at least two reflective sub-surfaces with different tilt angles, thereby improving the light extraction efficiency of the display unit 20.

[0078] like Figures 1 to 7 As shown, the display unit 20 in the above-mentioned display panel can be an organic light emitting diode, for example, the display unit 20 includes a first electrode 21, a light emitting layer 22 and a second electrode 23 stacked in sequence, wherein the first electrode 21 is located between the pixel defining layer 40 and the substrate 10, and a portion of the first electrode 21 is exposed in the pixel opening 41, the light emitting layer 22 is located in the pixel opening 41, and the voltage formed between the first electrode 21 and the second electrode 23 excites the light emitting layer 22 to emit light.

Figure 2 As shown, this embodiment provides a display device, which can be an OLED display device and a television including an OLED display device, a digital camera, a mobile phone, a tablet computer, a smart watch, an e-book, a navigator, or any other product or component with a display function.

In addition, since the light emitted by the display unit 20 is transmitted in various directions, and the orthographic projection of each reflection block 31 on the substrate 10 surrounds the orthographic projection of the display unit 20 on the substrate 10, the large-angle light emitted by the display unit 20 in multiple directions is reflected by the reflection block 31 to the front view direction, which is beneficial to improving the front view brightness of the display panel and improving the utilization rate of the light energy of the display unit 20. In addition, in order to further improve the light emission efficiency of the display unit 20, at least two reflection sub-surfaces with different inclination angles are provided on the surface of each reflection block 31 on the side away from the substrate 10, so that the light in different angle ranges is reflected by different reflection sub-surfaces to the front view direction, thereby improving the light emission efficiency of the display unit 20 and further improving the front view brightness of the display panel. The display panel in this embodiment has the characteristics of high brightness under the same power consumption and service life. At the same time, the display panel in this embodiment has lower power consumption and longer service life under the same brightness.
