Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of display technologies, and particularly to a display panel and a display device. Background Art
[0002] With the continuous development of science and technology, more and more display products, such as mobile phones, tablet computers, laptop computers, and smart wearable devices, etc., are widely used in people's daily lives and work, bringing great convenience to people's daily lives and work, and becoming an indispensable important tool for people today.
[0003] At the present stage, how to improve the yield rate of display products and reduce production costs has become one of the technical problems to be solved urgently. Summary of the Invention
[0004] To solve the above technical problems, the present disclosure provides a display panel and a display device, aiming to improve the product yield rate and reduce production costs.
[0005] In a first aspect, the present disclosure provides a display panel, including:
[0006] A first substrate and a second substrate disposed opposite to each other;
[0007] A light-emitting element located on a side of the first substrate facing the second substrate;
[0008] A light-reflecting component located on a side of the first substrate facing the second substrate and located on at least one side of the light-emitting element along a first direction, the first direction being parallel to the plane where the first substrate is located;
[0009] A light-dimming component located on a side of the second substrate facing the first substrate and overlapping with the light-emitting element along a direction perpendicular to the plane where the first substrate is located;
[0010] The light-dimming component includes a first light-dimming state and a second light-dimming state. In the first light-dimming state, the light-dimming surface of the light-dimming component is perpendicular to the plane where the first substrate is located; in the second light-dimming state, the light emitted by the light-emitting element is reflected by the light-dimming surface of the light-dimming component to the light-reflecting component and then emitted to the light-emitting surface of the display panel through the light-reflecting component.
[0011] In a second aspect, based on the same inventive concept, the present disclosure further provides a display device including the display panel provided in the first aspect of the present disclosure.
[0012] The technical solutions provided in the embodiments of the present disclosure have the following advantages compared with the prior art:
[0013] In the display panel and the display device provided by the embodiments of the present disclosure, in the first dimming state, the dimming surface of the dimming component is perpendicular to the plane where the first substrate is located. At this time, the light emitted by the light-emitting element corresponding to the dimming component can normally be emitted toward the light-emitting surface of the display panel, and the dimming surface does not process the light emitted by the light-emitting element. In the second dimming state, the dimming surface is inclined and faces the corresponding light-emitting element. After the light emitted by the light-emitting element is incident on the dimming surface, it is reflected by the dimming surface and then incident on the light-reflecting component. The light-reflecting component further reflects the received light so that the reflected light is incident on the light-emitting surface of the display panel. In this way, even if no light-emitting element is provided at the position where the light-reflecting component is located, the light-reflecting component can reflect the light to the light-emitting surface of the display panel. The area where the light-reflecting component is located, like the area where the light-emitting element is located, can be regarded as a pixel point and can emit light toward the light-emitting surface of the display panel. Therefore, introducing a smaller number of light-emitting elements in the display panel can achieve a higher pixel density. At the same time, since the number of light-emitting elements in the display panel is small, only a smaller number of light-emitting elements need to be transferred during the mass transfer process, which helps to avoid the problem of reduced yield caused by a large number of light-emitting elements. Therefore, it is beneficial to improve the product yield and reduce the production cost at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to more clearly understand the above objects, features, and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.
[0035] In the following description, many specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.
[0036] Figure 1 Shown is a top view of a display panel provided by an embodiment of the present disclosure. Figure 2 Shown as Figure 1 a cross-sectional view of the display panel in the AA direction in [reference], please refer to Figure 1 and Figure 2 , an embodiment of the present disclosure provides a display panel 100, including:
[0037] A first substrate 01 and a second substrate 02 which are oppositely arranged;
[0038] A light-emitting element 10, located on one side of the first substrate 01 facing the second substrate 02;
[0039] A light-reflecting member 20, located on one side of the first substrate 01 facing the second substrate 02, and located on at least one side of the light-emitting element 10 along a first direction D1, the first direction D1 being parallel to the plane where the first substrate 01 is located;
[0040] A light-dimming member 30, located on one side of the second substrate 02 facing the first substrate 01, and along a direction perpendicular to the plane where the first substrate 01 is located, the light-dimming member 30 overlapping with the light-emitting element 10;
[0041] The light-dimming member 30 includes a first light-dimming state and a second light-dimming state. In the first light-dimming state, a light-dimming surface M1 of the light-dimming member 30 is perpendicular to the plane where the first substrate 01 is located; in the second light-dimming state, light emitted by the light-emitting element 10 is reflected by the light-dimming surface M1 of the light-dimming member 30 to the light-reflecting member 20, and is emitted by the light-reflecting member 20 to the light-emitting surface of the display panel.
[0042] It should be noted that Figure 1 only a display panel with a rectangular structure is taken as an example for illustration, and the actual shape of the display panel is not limited. In some other embodiments of the present disclosure, the display panel may also be embodied in other feasible shapes such as a circle, a rounded rectangle, etc. Figure 1The embodiment illustrates the light-emitting elements 10 and the reflective components 20 in the display panel, but does not limit the actual number, shape and arrangement of the light-emitting elements 10 and the reflective components 20. Optionally, the display panel provided in this embodiment can be a display panel using inorganic light-emitting diode display technology, such as a Micro LED display panel, or a Mini LED display panel, etc., that is, the corresponding light-emitting element 10 in the display panel is a Micro LED or Mini LED. It should also be noted that in order to drive the light-emitting element 10 to emit light, a related driving circuit is also provided on the first substrate 01, and reference may be made to the contents of the related technology for this, and the present disclosure does not specifically limit this.
[0043] For display panels using inorganic diode display technology, in the actual production process, mass transfer is usually used to transfer the light-emitting elements 10 to the array substrate. In order to achieve the corresponding pixel density, the number of light-emitting elements 10 is usually large. However, the greater the number of light-emitting elements 10, the greater the probability of transfer errors occurring during the mass transfer process, which greatly affects the product yield and invisibly increases the production cost.
[0044] To solve the above problems, in the display panel 100 provided in the embodiment of the present disclosure, the light emitting element 10 and the reflective component 20 are simultaneously introduced on the side of the first substrate 01 facing the second substrate 02, and the dimming component 30 is introduced on the side of the second substrate 02 facing the first substrate 01, and the dimming component 30 is located in the light emitting direction of the light emitting element 10. The dimming surface M1 of the dimming component 30 can be adjusted relative to the second substrate 02, so that the dimming surface M1 and the second substrate 02 have different angles. The dimming component 30 is used to adjust the light of the light emitting element 10, Figure 3 The figure shows a relative position relationship diagram between the dimming surface M1 and the light emitting element 10 in the first dimming state. Figure 4 FIG. 1 is a diagram showing a relative position relationship between the dimming surface M1 and the light emitting element 10 in the second dimming state. Figure 3 In the first dimming state, the dimming surface M1 of the dimming component 30 is perpendicular to the plane where the first substrate 01 is located. At this time, the light emitted by the light-emitting element 10 corresponding to the dimming component 30 will be able to normally emit to the light-emitting surface of the display panel, and the dimming surface M1 does not process the light emitted by the light-emitting element 10. Please refer to Figure 4In the second dimming state, the dimming surface M1 is inclined and faces the corresponding light-emitting element 10 and the reflective component 20. After the light emitted by the light-emitting element 10 is directed to the dimming surface M1, it is reflected by the dimming surface M1 and directed to the reflective component 20. The reflective component 20 further reflects the received light so that the reflected light is directed to the light-emitting surface of the display panel. In this way, even if the light-emitting element 10 is not arranged at the position where the reflective component 20 is located, the reflective component 20 can also reflect the light to the light-emitting surface of the display panel. The area where the reflective component 20 is located is the same as the area where the light-emitting element 10 is located. Both can be regarded as a pixel point, which can emit light to the light-emitting surface of the display panel. Therefore, a higher pixel density can be achieved by introducing a smaller number of light-emitting elements 10 in the display panel. At the same time, since the number of light-emitting elements 10 in the display panel is small, only a smaller number of light-emitting elements 10 need to be transferred in the process of mass transfer, which is conducive to avoiding the problem of reduced yield due to a large number of light-emitting elements 10, so it is conducive to improving the product yield. At the same time, the reduction in the number of light-emitting elements 10 is also conducive to reducing production costs.
[0045] It should be noted that, for the same light-emitting element 10, the first dimming state and the second dimming state corresponding to the dimming component 30 are performed in a time-sharing manner, that is, when the light-emitting element 10 itself plays a display role, the dimming component 30 is in the first dimming state, and the area corresponding to the reflective component 20 is not displayed. When the light-emitting element 10 itself does not play a display role, its light is reflected by the dimming component 30 and the reflective component 20, and the area where the reflective component 20 is located acts as a display pixel.
[0046] The reflective component 20 provided in the embodiment of the present disclosure can be regarded as a structure having an inclined reflective surface M2, and its cross section is a triangular structure, and the reflective surface M2 of the reflective component 20 faces the corresponding dimming component 30. The reflective surface M2 of the reflective component 20 can be coated with a material with a high reflectivity such as Ag or Al.
[0047] Please refer to Figures 2 to 4 In an optional embodiment of the present disclosure, the dimming component 30 is an adjustable angle micromirror MEMS device. The adjustable angle micromirror MEMS device has a reflective surface, namely the dimming surface M1 mentioned in the above embodiment, and can realize changes in various angles or different orientations of the dimming surface M1 according to different driving voltages, thereby realizing different dimming states. For example, when the dimming surface M1 is controlled to be perpendicular to the plane where the first substrate 01 is located, it corresponds to the first dimming state, and when the dimming surface M1 is controlled to be in a non-vertical and non-parallel inclined structure with the plane where the first substrate 01 is located, it corresponds to the second dimming state. Optionally, before forming the adjustable angle micromirror MEMS device, a supporting structure can be pre-formed using photoresist so that the adjustable angle micromirror MEMS device can be placed on the supporting structure.
[0048] When the display panel includes N light-emitting elements 10, if a light-reflecting component 20 and a light-dimming component 30 are introduced for each light-emitting element 10, the area corresponding to each light-reflecting component 20 can be regarded as a display pixel. In this way, there will be 2N display pixels in the display panel, and a higher pixel density is achieved with fewer light-emitting elements 10. Of course, the embodiments of the present disclosure do not limit the number of the light-reflecting component 20 and the light-dimming component 30 corresponding to the light-emitting element 10. For example, please refer to Figure 5 and Figure 6 , Figure 5 The figure shows a top view of the light-emitting element 10 and the light-reflecting component 20 corresponding to the light-emitting element 10. Figure 6 The figure shows Figure 5 a cross-sectional view taken along the BB direction. In an alternative embodiment of the present disclosure, along the first direction D1, the light-reflecting components 20 corresponding to the same light-emitting element 10 are located on both sides of the light-emitting element 10.
[0049] Specifically, this embodiment shows a solution in which one light-emitting element 10 corresponds to two light-reflecting components 20. The two light-reflecting components 20 are respectively located on both sides of the light-emitting element 10 along the first direction D1. In the second light-dimming state of the light-dimming component 30, the light-dimming surface M1 of the light-dimming component 30 above the light-emitting element 10 can present different angles. When the light-dimming surface M1 faces the light-emitting element 10 and the light-reflecting component 20 on the left side of the light-emitting element 10, the light emitted by the light-emitting element 10 can be reflected to the left light-reflecting component 20 after being reflected by the light-dimming surface M1, and then emitted from the light-reflecting component 20 to the light-emitting surface of the display panel. When the light-dimming surface M1 of the light-dimming component 30 faces the light-emitting element 10 and the light-reflecting component 20 on the right side of the light-emitting element 10, the light emitted by the light-emitting element 10 can be reflected to the right light-reflecting component 20 after being reflected by the light-dimming surface M1, and then emitted from the light-reflecting component 20 to the light-emitting surface of the display panel. When two or more light-reflecting components 20 are provided for the same light-emitting element 10, the process of reflecting the light emitted by the light-emitting element 10 to different light-reflecting components 20 by the light-dimming component 30 is carried out in a time-sharing manner. When two light-reflecting components 20 are provided for each light-emitting element 10 in the display panel, assuming there are N light-emitting elements 10, the area corresponding to each light-reflecting component 20 can be regarded as a display pixel. In this way, there will be 3N display pixels in the display panel, which means that a higher pixel density is achieved with a smaller number of light-emitting elements 10, which is more conducive to reducing the number of light-emitting elements 10 actually included in the display panel, improving the product yield, and saving production costs.
[0050] Please continue to refer to Figure 5 and Figure 6, in an alternative embodiment of the present disclosure, the light reflecting members 20 located on both sides of the same light emitting element 10 and corresponding to the light emitting element 10 are symmetrically arranged. When the two light reflecting members 20 corresponding to the same light emitting element 10 are symmetrically arranged, the angles between the light reflecting surfaces M2 and the bottom surfaces M0 of the two light reflecting members 20 are the same, and the two light reflecting members 20 corresponding to the same light emitting element 10 can be made of the same structure, which is beneficial to simplifying the overall structure of the display panel. In addition, when the two light reflecting members 20 corresponding to the same light emitting element 10 are symmetrically arranged, when the light regulating member 30 reflects light to the light reflecting member 20, the orientations of the light regulating surfaces M1 of the light regulating member 30 are different, but the deflection angles are the same relative to the positions of the light regulating surfaces M1 in the first light regulating state, which is beneficial to reducing the control difficulty of the light regulating member 30.
[0051] Figure 5 and Figure 6 The illustrated embodiment shows a solution in which when the number of the light reflecting members 20 corresponding to the same light emitting element 10 is two, the two light reflecting members 20 are respectively arranged on both sides of the light emitting element 10 along the first direction D1. However, the present disclosure is not limited thereto. In some other embodiments of the present disclosure, the light reflecting members 20 corresponding to the same light emitting element 10 may also be arranged on the same side of the light emitting element 10 along the first direction D1. For example, please refer to Figure 7 and Figure 8 , Figure 7 The figure shown is a top view of the light emitting element 10 and the light reflecting member 20 corresponding to the light emitting element 10. Figure 8 The figure shown is Figure 7 a CC-direction cross-sectional view of, please refer to Figure 7 and Figure 8 , in an alternative embodiment of the present disclosure, there are at least N light reflecting members 20 located on the same side of the light emitting element 10 along the first direction D1, and the N light reflecting members 20 all correspond to the same light emitting element 10, where N≥2.
[0052] Specifically, Figure 7 and Figure 8The illustrated embodiment shows a solution in which two corresponding light-reflecting components 20 are provided on the same side of the light-emitting element 10. At this time, the light-emitting element 10 and the two corresponding light-reflecting components 20 can be regarded as three different pixel points, and the three pixel points can be displayed time-divisionally. When the light-emitting element 10 needs to be displayed, the dimming surface M1 of the dimming component 30 corresponding to the light-emitting element 10 is arranged perpendicular to the first substrate 01, and the light emitted by the light-emitting element 10 can directly irradiate the light-emitting surface of the display panel. When the area where the light-reflecting component 20 is located needs to play a display role, the dimming surface M1 corresponding to the light-emitting element 10 is inclined and faces the light-emitting element 10 and the light-reflecting component 20. The light emitted by the light-emitting element 10 is reflected by the dimming surface M1 and then irradiates the light-reflecting component 20, and then is reflected by the light-reflecting component 20 and irradiates the light-emitting surface of the display panel. When different areas where the corresponding light-reflecting components 20 of the light-emitting element 10 play a display role, the angles of the dimming surfaces M1 corresponding to different light-reflecting components 20 are different, which will be described in subsequent embodiments. In this way, the corresponding light-reflecting components 20 can be provided on the same side or different sides of the light-emitting element 10 along the first direction D1, and the requirement of a high PPI is achieved by introducing a small number of light-emitting elements 10. It should be noted that three or more light-reflecting components 20 can also be provided on the same side of the light-emitting element 10 along the first direction D1, and the present disclosure does not limit this.
[0053] Please continue to refer to Figure 7 and Figure 8 , in an alternative embodiment of the present disclosure, the light-reflecting components 20 located on the same side of the light-emitting element 10 along the first direction D1 include a first light-reflecting component 21 and a second light-reflecting component 22, and the first light-reflecting component 21 is located between the second light-reflecting component 22 and the light-emitting element 10; the second dimming state includes a first sub-state and a second sub-state. In the first sub-state, the light reflected by the dimming surface M1 of the dimming component 30 irradiates the first light-reflecting component 21; in the second sub-state, the light reflected by the dimming surface M1 of the dimming component 30 irradiates the second light-reflecting component 22; in the first sub-state, the acute angle in the angle between the dimming surface M1 and the plane where the first substrate 01 is located is α; in the second sub-state, the acute angle in the angle between the dimming surface M1 and the plane where the first substrate 01 is located is β, where α < β.
[0054] In this embodiment, by adjusting the angle of the dimming surface M1, in the second dimming state, the first reflecting member 21 and the second reflecting member 22 can reflect light to the light-emitting surface of the display panel at different times to perform the display function. Assume that the state in which the first reflecting member 21 performs the display function is the first sub-state, and the state in which the second reflecting member 22 performs the display function is the second sub-state. In the first sub-state and the second sub-state, the dimming surface M1 faces the light-emitting element 10, the first reflecting member 21, and the second reflecting member 22. Since the first reflecting member 21 is located between the second reflecting member 22 and the light-emitting element 10, when the acute angle α between the dimming surface M1 and the plane of the first substrate 01 in the first sub-state is set to be less than the acute angle β between the dimming surface M1 and the plane of the first substrate 01 in the second sub-state, the light emitted through the dimming surface M1 in the first sub-state can be accurately projected onto the first reflecting member 21, and the light reflected by the dimming surface M1 in the second sub-state can be accurately projected onto the second reflecting member 22. This is beneficial to improving the display accuracy when the first reflecting member 21 and the second reflecting member 22 perform the display function respectively.
[0055] Please continue to refer to Figure 7 and Figure 8 , in an alternative embodiment of the present disclosure, the reflecting member 20 includes a reflecting surface M2 and a bottom surface M0, and the first included angle between the reflecting surface M2 and the bottom surface M0 is an acute angle. The first included angle corresponding to the first reflecting member 21 is θ1, and the first included angle corresponding to the second reflecting member 22 is θ2, where θ1 = θ2. When the first included angles in different reflecting members 20 corresponding to the same light-emitting element 10 are set to be the same, the structures of different reflecting members 20 do not need to be designed differently, which is beneficial to simplifying the manufacturing process of the display panel. Optionally, the first included angles of the reflecting members 20 corresponding to different light-emitting elements 10 can also be set to be the same. In this way, the reflecting members 20 in the entire display panel can be manufactured using the same size and structure standards, which is even more beneficial to simplifying the manufacturing process of the display panel. It should be noted that when the reflecting members 20 are manufactured using the same standard, the direction of the light reflected through the dimming surface M1 can be controlled by controlling the angle of the dimming surface M1 to achieve the normal display function of the corresponding areas of different reflecting members 20.
[0056] The above embodiment only shows the positional relationship diagram of one light-emitting element 10 in the display panel and the reflecting member 20 corresponding thereto. When there are multiple light-emitting elements 10 with different emission colors in the display panel, the positional relationship between the light-emitting elements 10 and the reflecting members 20 can be referred to Figure 9 and Figure 10 , Figure 9 shows another top view of the light-emitting element 10 and the reflecting member 20 corresponding to the light-emitting element 10, Figure 10 showsFigure 9 A DD cross-sectional view, please refer to Figure 9 and Figure 10 , in an alternative embodiment of the present disclosure, the light-emitting element 10 includes a first light-emitting element 11, a second light-emitting element 12, and a third light-emitting element 13, and the first light-emitting element 11, the second light-emitting element 12, and the third light-emitting element 13 have different light-emitting colors; the display panel includes a plurality of light-emitting units P0, and each light-emitting unit P0 includes a first light-emitting element 11, a second light-emitting element 12, and a third light-emitting element 13. Along the first direction D1, the reflective member 20 is located on at least one side of the light-emitting unit P0.
[0057] Optionally, the light-emitting colors of the first light-emitting element 11, the second light-emitting element 12, and the third light-emitting element 13 are red, green, and blue respectively. In this embodiment, an example is given where a first light-emitting element 11, a second light-emitting element 12, and a third light-emitting element 13 arranged along the first direction D1 form a light-emitting unit P0. The reflective member 20 is located on at least one side of the entire single light-emitting unit P0 along the first direction D1. In this way, no reflective member 20 is provided between different light-emitting elements 10 in a single light-emitting unit P0, which is beneficial to avoiding affecting the image display function of different light-emitting elements 10 in the light-emitting unit P0. Optionally, when the reflective member 20 is provided on at least one side of the light-emitting unit P0 along the first direction D1, when each light-emitting element 10 in the light-emitting unit P0 corresponds to a reflective member 20 respectively, the three reflective members 20 can be located on the same side of the light-emitting unit P0 along the first direction D1. For example, please refer to Figure 9 and Figure 10 , at this time, the three reflective members 20 can be regarded as a pixel unit P1 for displaying an image, and the light-emitting unit P0 can also be regarded as a pixel unit, which is equivalent to introducing a pixel unit P1 including the light-emitting element 10 to achieve the display effect of two pixel units P1, which is beneficial to improving the PPI of the display panel. In addition, when each light-emitting element 10 in the light-emitting unit P0 corresponds to two reflective members 20 respectively, the two reflective members 20 corresponding to one light-emitting element 10 in the light-emitting unit P0 can be located on both sides of the light-emitting unit P0 along the first direction D1. For example, please refer to Figure 11 and Figure 12 , Figure 11 Shown is another top view of the light-emitting element 10 and the reflective member 20 corresponding to the light-emitting element 10. Figure 12 Shown is Figure 11An EE cross-sectional view, so that two pixel units P1 for displaying images can be formed on both sides of the light-emitting unit P0 along the first direction D1. The light-emitting unit P0 can also be regarded as a pixel unit P1. It is equivalent to achieving the display effect of three pixel units P1 by introducing one pixel unit P1 containing the light-emitting element 10, which is beneficial to improving the PPI of the display panel and enhancing the display effect.
[0058] Please continue to refer to Figure 11 and Figure 12 In an alternative embodiment of the present disclosure, the dimming component 30 includes a first dimming component 31, a second dimming component 32, and a third dimming component 33, and the light-reflecting component 20 includes a first light-reflecting component 21, a second light-reflecting component 22, and a third light-reflecting component 23. The first dimming component 31 and the first light-reflecting component 21 both correspond to the first light-emitting element 11, the second dimming component 32 and the second light-reflecting component 22 both correspond to the second light-emitting element 12, and the third dimming component 33 and the third light-reflecting component 23 both correspond to the third light-emitting element 13. On the same side of the light-emitting unit P0 along the first direction D1, the distance between the first light-emitting element 11 and the first light-reflecting component 21 is S1, the distance between the second light-emitting element 12 and the second light-reflecting component 22 is S2, and the distance between the third light-emitting element 13 and the third light-reflecting component 23 is S3, and S1 = S2 = S3. Assuming that the three light-reflecting components 20 corresponding to the three light-emitting elements 10 in the same light-emitting unit P0 and located on the same side of the light-emitting unit P0 form a pixel unit P1, when S1 = S2 = S3 is set, it is equivalent to that the arrangement order of the light-emitting elements 10 in the light-emitting unit P0 is the same as the arrangement order of the light-reflecting components 20 in the pixel unit P1 corresponding to the light-emitting unit P0. For example, when the light-emitting elements 10 in the light-emitting unit P0 are arranged in sequence from left to right as the first light-emitting element 11 (assuming to emit red light), the second light-emitting element 12 (assuming to emit green light), and the third light-emitting element 13 (assuming to emit blue light), the light-reflecting components 20 in the pixel unit P1 are arranged in sequence from left to right as the first light-reflecting component 21 (reflecting red light), the second light-reflecting component 22 (reflecting green light), and the third light-reflecting component 23 (reflecting blue light). With such a setting, in the second dimming state, when the dimming surfaces M1 corresponding to different light-emitting elements 10 in the same light-emitting unit P0 reflect light to the light-reflecting components 20 in the same pixel unit P1, the orientations of the respective dimming surfaces M1 and the angles with the first substrate 01 can be set to be the same, which is beneficial to simplifying the control difficulty of the dimming component 30.
[0059] Figure 13 Shown is a relative position relationship diagram of the dimming component 30 and the light-emitting element 10 in the first dimming state. Figure 14 Shown is a relative position relationship diagram of the dimming component 30 and the light-emitting element 10 in the second dimming state. Figure 12It can be regarded as another relative position relationship diagram of the dimming component 30 and the light-emitting element 10 in the second dimming state. Please refer to Figure 13 , in an alternative embodiment of the present disclosure, at the same moment in the first dimming state, the dimming surfaces M1 of the first dimming component 31, the dimming surfaces M1 of the second dimming component 32, and the dimming surfaces M1 of the third dimming component 33 are all perpendicular to the plane where the first substrate 01 is located. At this time, the light emitted by the first light-emitting element 11, the second light-emitting element 12, and the third light-emitting element 13 will not be reflected by the dimming surface M1, but directly shoot towards the light-emitting surface of the display panel. The light-emitting units P0 corresponding to the first light-emitting element 11, the second light-emitting element 12, and the third light-emitting element 13 are used to display images. Please refer to Figure 12 and Figure 14 , at the same moment in the second dimming state, the light reflected by the first dimming component 31 shoots towards the first light-reflecting component 21, the light reflected by the second dimming component 32 shoots towards the second light-reflecting component 22, and the light reflected by the third dimming component 33 shoots towards the third light-reflecting component 23. It should be noted that at the same moment in the second dimming state, the dimming surfaces M1 corresponding to different light-emitting elements 10 in the same light-emitting unit P0 are facing the light-reflecting component 20 on the same side of the light-emitting unit P0. That is to say, the light-reflecting components 20 located on the same side of the light-emitting unit P0 and corresponding to the light-emitting elements 10 in the light-emitting unit P0 reflect light simultaneously, and the three light-reflecting components 20 reflect light towards the light-emitting surface of the display panel simultaneously to achieve the display function. When displaying, when the light of the three light-emitting elements 10 in the light-emitting unit P0 directly shoots towards the light-emitting surface of the display panel to perform the display function, the light-reflecting component 20 corresponding to the light-emitting unit P0 does not reflect light towards the light-emitting surface of the display panel. When the light-reflecting component 20 corresponding to the light-emitting element 10 emits light towards the light-emitting surface of the display panel, the three light-emitting elements 10 in the light-emitting unit P0 do not directly emit light towards the light-emitting surface of the display panel. That is to say, the area where the light-emitting unit P0 and the corresponding light-reflecting component 20 are located is displayed in a time-sharing manner. However, due to the hysteresis of the human eye, it may not be noticed that it is a time-sharing display, so it will not affect the overall display effect.
[0060] Please refer to Figures 12 to 14, in an alternative embodiment of the present disclosure, the reflective member 20 includes a reflective surface M2 and a bottom surface M0. The first included angle θ between the reflective surface M2 and the bottom surface M0 is an acute angle, and the first included angles θ corresponding to the first reflective member 21, the second reflective member 22, and the third reflective member 23 are equal. The bottom surface M0 of the reflective member 20 can be regarded as a plane parallel to the plane where the first substrate 01 is located, and its reflective surface M2 is located on the side of the bottom surface M0 away from the first substrate 01. The reflective member 20 may further include an upright surface perpendicular to the first substrate 01, and this upright surface is used to connect the aforementioned bottom surface M0 and the reflective surface M2. Among them, the first included angle θ between the reflective surface M2 and the bottom surface M0 is coordinated with the inclination of the dimming surface M1 of the dimming member 30, so as to reflect as much light as possible to the light-emitting surface of the display panel in the second dimming state. When the first reflective member 21, the second reflective member 22, and the third reflective member 23 are respectively provided for the first light-emitting element 11, the second light-emitting element 12, and the third light-emitting element 13 in the light-emitting unit P0, in this embodiment, the magnitudes of the first included angles θ corresponding to the first reflective member 21, the second reflective member 22, and the third reflective member 23 are all equal. In this way, the same size standard can be used to manufacture the first reflective member 21, the second reflective member 22, and the third reflective member 23, without differentiating the structures of the first reflective member 21, the second reflective member 22, and the third reflective member 23. Only by controlling the angles of the dimming surfaces M1 of the dimming members 30 corresponding to different reflective members 20 can the precise reception and reflection of light be achieved, which is beneficial to simplifying the structure of the display panel, reducing the manufacturing difficulty, and improving the production efficiency.
[0061] The foregoing embodiment shows a scheme in which different light-emitting elements 10 in the same light-emitting unit P0 respectively correspond to different reflective members 20. That is to say, the light emitted by different light-emitting elements 10 in the same light-emitting unit P0 will be reflected to different reflective members 20 in the second dimming state. In some other embodiments of the present disclosure, the light emitted by different light-emitting elements 10 in the same light-emitting unit P0 can also be reflected by the same reflective member 20 in the second dimming state. For example, please refer to Figure 15 and Figure 16 , Figure 15 shows a relative position relationship diagram of the dimming member 30 and the light-emitting element 10 in the first dimming state, Figure 16 shows Figure 15 a cross-sectional view in the FF direction of Figure 17 shows Figure 15Another cross-sectional view in the FF direction. In an alternative embodiment of the present disclosure, the dimming component 30 includes a first dimming component 31, a second dimming component 32, and a third dimming component 33. The first dimming component 31 corresponds to the first light-emitting element 11, the second dimming component 32 corresponds to the second light-emitting element 12, and the third dimming component 33 corresponds to the third light-emitting element 13. At the same moment in the first dimming state, the dimming surfaces M1 of the first dimming component 31, the dimming surfaces M1 of the second dimming component 32, and the dimming surfaces M1 of the third dimming component 33 are all perpendicular to the plane where the first substrate 01 is located. At the same moment in the second dimming state, the light rays reflected by the first dimming component 31, the second dimming component 32, and the third dimming component 33 are directed towards the same reflecting component 20.
[0062] Please refer to Figure 15 and Figure 16 , in this embodiment, the number of reflecting components 20 corresponding to different light-emitting elements 10 in the light-emitting unit P0 is different from that in the previous embodiment. In the previous embodiment, on the same side of the light-emitting unit P0 along the first direction D1, different light-emitting elements 10 in the light-emitting unit P0 correspond to different reflecting components 20. After the light rays emitted by different reflecting elements are reflected by the dimming surface M1, they are reflected to different reflecting components 20. In this embodiment, on the same side of the light-emitting unit P0 along the first direction D1, different light-emitting elements 10 in the light-emitting unit P0 can correspond to the same reflecting component 20. In the second dimming state, the light rays emitted by the three light-emitting elements 10 in the light-emitting unit P0 are respectively reflected by the first dimming component 31, the second dimming component 32, and the third dimming component 33, and then the light rays reflected by different dimming components 30 are directed onto the reflecting surface M2 of the same reflecting component 20 located on one side of the light-emitting unit P0. After being reflected by this reflecting component 20, they are directed towards the light-emitting surface of the display panel. In this way, on the same side of the light-emitting unit P0, introducing one or more relatively large reflecting components 20 for different light-emitting elements 10 in the same light-emitting unit P0 can also achieve the display function of the area where the reflecting component 20 is located through reflection. This method is beneficial to reducing the number of reflecting components 20 included in the display panel and simplifying the overall structure of the display panel.
[0063] It should be noted that the relatively large reflecting component 20 corresponding to the light-emitting unit P0 can be located on one side or both sides of the light-emitting unit P0. On the same side of the light-emitting unit P0 along the first direction D1, one or more different relatively large reflecting components 20 can be provided. The relatively large reflecting component 20 referred to here means the reflecting component 20 that is used to receive the light rays reflected by three different light-emitting elements 10 through different dimming surfaces M1 in the second dimming state. In the second dimming state, the orientations and inclination angles of the dimming surfaces M1 of the dimming components 30 corresponding to different light-emitting elements 10 in the same light-emitting unit P0 can be set to be the same.
[0064] Please refer to Figure 15 and Figure 17 Moreover, the size of the light reflecting member 20 on the same side of the light emitting unit along the first direction can be set to be smaller. At this time, by differentially setting the angles between the light modulating surfaces of the three light modulating members 30 corresponding to the same light emitting unit and the second substrate 02, the light reflected by the light modulating surfaces of the three light modulating members 30 can be made to be incident on the same area of the light reflecting member 20 with a smaller size only. For example Figure 17 In the embodiment shown, the third light emitting element 13 is closest to the right light reflecting member 20, and the first light emitting element 11 is farthest from the right light reflecting member 20. Therefore, the angle between the light modulating surface of the third light modulating member 33 corresponding to the third light emitting element 13 and the second substrate 02 can be set to be the smallest, the acute angle between the light modulating surface of the first light modulating member 31 and the second substrate 02 can be set to be the largest, and the acute angle between the light modulating surface of the second light modulating member 32 and the second substrate 02 can be set to be in the middle, so as to control the light reflected by the first light modulating member 31, the second light modulating member 32 and the third light modulating member 33 in the second light modulating state to be concentrated and incident on the same area of the same light reflecting member 20. It should be noted that Figure 17 The embodiment shown only takes the example of the light modulating surface corresponding to the same light emitting unit reflecting light to the light reflecting member on its right side in the second light modulating state. When it is necessary to reflect light to the light reflecting member on its left side, a similar setting method can also be adopted, that is, the closer to the light reflecting member, the smaller the acute angle between the light modulating surface of the light modulating member and the second substrate, and the farther from the light reflecting member, the larger the acute angle between the light modulating surface of the light modulating member and the second substrate. In this way, by differentially designing the acute angles between the light modulating surfaces of different light modulating members 30 corresponding to the same light emitting unit and the second substrate 02, the size and quantity of the light reflecting members introduced in the display panel can be reduced, so that more space in the display panel can be vacated to place light emitting elements or light reflecting members, which is more conducive to improving the pixel density of the display panel and enhancing the display effect
