[0041] Next, the embodiments in the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.
[0042] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below in conjunction with the drawings and specific implementation manners.
[0043] As described in the background art section, how to improve the display quality of electronic paper has become one of the research directions of those skilled in the art.
[0044] Specifically, when the electronic paper is displaying, there is an obvious "lamp shadow" phenomenon. Therefore, the "lamp shadow" problem has become an important factor affecting the display effect of the electronic paper. It should be noted that the "lamp shadow" phenomenon refers to the shadow or virtual shadow phenomenon that appears on the surface of the electronic paper display screen under specific angles and light conditions. This not only affects the visual effect of the electronic paper but also reduces the user's reading and usage experience.
[0045] In addition, with the continuous improvement of user requirements, the border of the electronic paper display screen is getting narrower and narrower, and the "lamp shadow" problem of the electronic paper display screen is becoming more and more serious. For the dual-color-temperature electronic paper display screen, because two different colors of light sources need to be arranged within the same border size, its "lamp shadow" problem is more serious.
[0046] In view of this, the embodiments of the present application provide a display panel, as Figure 1 shown, the display panel includes:
[0047] A display component 10. Optionally, the display component 10 is an electronic paper display component;
[0048] A light guide plate 20 is disposed on one side facing the display surface of the display component 10. That is, in this embodiment, the light guide plate 20 is located on the display side of the display component 10, and the light-emitting side of the light guide plate 20 is disposed opposite to the display side of the display component 10, where the display side of the display component 10 is the side of the display component for presenting the display content;
[0049] A light source assembly 30 is disposed on the light incident side of the light guide plate 20 for emitting a light beam to the light guide plate 20;
[0050] A dimming structure 40 is disposed between the light source assembly 30 and the light guide plate 20 for modulating the light beam emitted by the light source assembly 30 and then entering the light guide plate 20 through the light incident surface of the light guide plate 20. The light incident surface is a surface disposed on the light incident side of the light guide plate 20.
[0051] It should be noted that in this embodiment, the dimming structure can perform modulations such as shaping, diffusing, splitting, and / or beam splitting on the light emitted by the light source assembly. The present application does not limit this, as long as it can adjust the light uniformity of the light incident on different positions of the light incident surface of the light guide plate.
[0052] Optionally, in an embodiment of the present application, a plurality of dimming elements 21 are disposed on the side of the light guide plate 20 facing the display assembly 10. The dimming elements 21 are used to increase the mixing degree of the light emitted by the light guide plate 20 and improve the uniformity of the light emitted by the light guide plate 20.
[0053] It should be noted that in specific applications, the light received by the area of the light guide plate close to the light source assembly has a higher brightness, and the light received by the area far from the light source assembly has a lower brightness. Therefore, in an embodiment of the present application, the density of the dimming elements disposed in the area of the light guide plate close to the light source assembly is greater than the density of the dimming elements disposed in the area of the light guide plate far from the light source assembly, so as to further improve the uniformity of the light emitted by the light guide plate. Optionally, along the direction away from the light source assembly, the setting density of the dimming elements on the light guide plate gradually decreases, but the present application does not limit this, and it depends on the specific situation.
[0054] In addition to including a display assembly, a light guide plate, and a light source assembly, the display panel provided by the embodiment of the present application further includes a dimming structure located between the light source assembly and the light guide plate. In specific applications, the light beam emitted by the light source assembly is first modulated by the dimming structure and then enters the light guide plate, so that the dimming structure can be used to modulate the light beam emitted by the light source assembly, reduce the difference in the amount of light between different regions of the light incident surface of the light guide plate, improve the light uniformity of the light incident surface of the light guide plate, and further improve the uniformity of the light emitted by the light guide plate, relieve the "lamp shadow" problem during the display of the display panel, and improve the display quality.
[0055] Specifically, in an embodiment of the present application, the light incident surface of the light guide plate is located on the side surface of the light guide plate, and the dimming structure is located between the light source assembly and the light incident surface of the light guide plate, that is, the dimming structure is located on the side surface of the light guide plate, so that the setting of the dimming structure will not affect the display light of the display assembly, and on the basis of alleviating the "lamp shadow" problem during the display of the display panel, it will not affect the display of the display content of the display assembly.
[0056] Optionally, in an embodiment of the present application, in the direction perpendicular to the plane where the light guide plate is located (i.e., the thickness direction of the light guide plate), the size of the dimming structure is not less than the thickness of the light guide plate, so that as much as possible of the light entering the light incident surface of the light guide plate is the light modulated by the dimming structure, thereby improving the uniformity of the light on the light incident surface of the light guide plate, and further improving the uniformity of the light emitted from the light guide plate, alleviating the "lamp shadow" problem during the display of the display panel, and improving the display quality.
[0057] Specifically, in an embodiment of the present application, the light source assembly may include LED lamp beads, may also include LED light strips, and may also include a liquid crystal cell or other types of light-emitting components. The present application does not limit this, and it depends on the specific situation.
[0058] Specifically, in an embodiment of the present application, the light source assembly may include multiple groups of lamp beads arranged at intervals, or may include multiple light strips. Among them, if the light source assembly includes multiple light strips, one light strip covers different positions of the light guide plate in the second direction, where the second direction may be the length direction parallel to the light incident surface of the light guide plate, or may be the width direction parallel to the light incident surface of the light guide plate (i.e., the thickness direction of the light guide plate). The present application does not limit this, and it depends on the specific situation.
[0059] On the basis of any of the above embodiments, in an embodiment of the present application, continue as Figure 1 shown, there is a first distance between the dimming structure 40 and the light-emitting component in the light source assembly 30, and there is a second distance between the dimming structure 40 and the light guide plate 20. Both the first distance and the second distance are greater than zero, so as to increase the light coupling distance between the light-emitting component of the light source assembly 30 and the dimming structure 40 and the light coupling distance between the light guide plate 20 and the dimming structure, improve the uniformity of the light incident on the light incident surface of the light guide plate 20, and further improve the uniformity of the light emitted from the light guide plate, alleviate the "lamp shadow" phenomenon during the display of the display panel, and improve the display quality of the display panel.
[0060] In an embodiment of the present application, as Figure 2As shown, there is a first distance between the dimming structure 40 and the light-emitting component of the light source assembly 30, and the first distance is greater than zero, so as to increase the light coupling distance between the light-emitting component in the light source assembly 30 and the dimming structure 40, and improve the uniformity of the light incident to the dimming structure 40. The dimming structure 40 is adjacent to the light guide plate 20, thereby reducing the dimming structure 40 and the light guide plate 20, so that the light incident on the light incident surface of the light guide plate 20 comes from the dimming structure as much as possible.
[0061] Specifically, in one embodiment of the present application, continue as follows Figure 2 As shown, the light emitting surface of the dimming structure 40 at least covers a portion of the edge of the light incident surface of the light guide plate 20, so that the light incident at at least a portion of the edge of the light guide plate 20 is also the light emitted after being modulated by the dimming structure, thereby improving the light uniformity at different positions of the light incident surface of the light guide plate 20, and further improving the light uniformity at different positions of the light emitting surface of the light guide plate 20, alleviating the "light shadow" phenomenon when the display panel is displaying, and improving the display quality of the display panel.
[0062] Optionally, in one embodiment of the present application, the light emitting surface of the dimming structure completely covers each edge of the light incident surface of the light guide plate, so that the light incident at each edge of the light incident surface of the light guide plate is light modulated by the dimming structure, and further the light incident at each point of the light incident surface of the light guide plate is light modulated by the dimming structure, thereby improving the uniformity of light at different positions of the light incident surface of the light guide plate, further alleviating the "light shadow" phenomenon when the display panel is displaying, and improving the display quality of the display panel.
[0063] Specifically, in one embodiment of the present application, the dimming structure is a strip structure or a block structure. In this embodiment, a first slot is provided on the side of the dimming structure facing the light guide plate, and at least a portion of the edge of the light guide plate corresponding to the first slot is accommodated in the first slot, so that the light output surface of the dimming structure at least covers a portion of the edge of the light incident surface of the light guide plate, so that the light incident at at least a portion of the edge of the light incident surface of the light guide plate is also the light emitted after modulation by the dimming structure, thereby improving the light uniformity at different positions of the light incident surface of the light guide plate, and further improving the light uniformity at different positions of the light output surface of the light guide plate, alleviating the "light shadow" phenomenon when the display panel is displayed, and improving the display quality of the display panel.
[0064] Optionally, in an embodiment of the present application, when the dimming structure is a block structure, a first notch is provided on the side of the dimming structure facing the light guide plate, and a partial edge of the light guide plate corresponding to the first notch is received in the first notch; when the dimming structure is a strip structure, a first notch is provided on the side of the dimming structure facing the light guide plate, and the entire edge of the light guide plate corresponding to the first notch is received in the first notch. However, the present application does not limit this, and it depends on the specific situation.
[0065] In another embodiment of the present application, the dimming structure is a film structure. In this embodiment, the dimming structure is coated on the light incident surface of the light guide plate, so that the light emitting surface of the dimming structure completely covers the light incident surface of the light guide plate, so that the light incident at each position of the light incident surface of the light guide plate is the light emitted after being modulated by the dimming structure, improving the light uniformity at different positions of the light incident surface of the light guide plate, and further improving the light uniformity at different positions of the light emitting surface of the light guide plate, alleviating the "lamp shadow" phenomenon during the display of the display panel, and improving the display quality of the display panel.
[0066] Based on any of the above embodiments, in an embodiment of the present application, continue as Figure 1 and Figure 2 shown, the light source assembly 30 includes a light emitting member 31 and a carrier 32 for carrying the light emitting member 31 and its electronic components. Among them, the electronic components can at least transmit signals for controlling its light emitting parameters to the light emitting member 31. Optionally, the carrier is a circuit board substrate, but the present application does not limit this, and it depends on the specific situation.
[0067] Based on the above embodiments, in an embodiment of the present application, as Figure 3 shown, the dimming structure 40 is coated on the light emitting member 31, and a partial edge of the light guide plate 20 abuts against the first side of the carrier 32 where the light emitting member 31 is provided, so that the light guide plate 20 is located on the light emitting side of the light emitting member 31, facilitating the light guide plate 20 to receive the light emitted by the light emitting member 31, and at the same time reducing the amount of light emitted by the light emitting member 31 that is emitted from the gap between the carrier 32 and the light guide plate 20, improving the utilization rate of the light emitted by the light emitting member 31.
[0068] It should be noted that, in this embodiment, the dimming structure is coated on the light-emitting element, and it can also make all the light emitted by the light-emitting element pass through the dimming structure and then enter the space where the light guide plate is located; optionally, there is a second distance between the dimming structure and the light guide plate, and the second distance is greater than zero, so as to increase the light coupling distance between the dimming structure and the light guide plate on the basis of ensuring that all the light incident on the light incident surface of the light guide plate comes from the light exit surface of the dimming structure, further improve the light uniformity of the light incident on the light incident surface of the light guide plate, and then improve the light uniformity of the light exit surface of the light guide plate, relieve the "lamp shadow" phenomenon during the display of the display panel, and improve the display quality of the display panel.
[0069] Optionally, in an embodiment of the present application, the dimming structure is a film structure to facilitate coating the dimming structure on the light-emitting element, but the present application does not limit this. In other embodiments of the present application, the dimming structure can also be a block structure or a strip structure, depending on the specific situation.
[0070] It should be noted that, in any of the above embodiments, when the dimming structure is a block structure or a strip structure, the dimming structure can be fixed on the carrier in the light source assembly; when the dimming structure is a film structure, the dimming structure can be directly attached to the light incident surface of the light guide plate or the light exit surface of the light-emitting element. It should also be noted that when the dimming structure is a block structure or a strip structure, and a first notch is provided on the side of the dimming structure facing the light guide plate, and at least part of the edge of the light guide plate corresponding to the first notch is received in the first notch, the dimming structure can also be adhered to the light guide plate. The present application does not limit this, and it depends on the specific situation.
[0071] On the basis of any of the above embodiments, in an embodiment of the present application, the dimming structure includes a plate body with a thickness and a dimming portion provided on the plate body.

It should be noted that, in this embodiment, the first direction can be a direction parallel to the thickness direction of the plate body or a direction perpendicular to the thickness direction of the plate body.
[0072] It should be noted that when the plate body is arranged between the light source assembly and the light guide plate in the first direction, compared with the case where the first direction is perpendicular to the thickness of the plate body, when the first direction is parallel to the thickness of the plate body, the width occupied by the dimming structure between the light source assembly and the light guide plate is smaller, which is more conducive to realizing the narrow border of the display panel.
[0073] Optionally, in an embodiment of the present application, the plate body is a columnar structure to facilitate the placement of the plate body. Specifically, the plate body can be a quadrangular prism, such as a cuboid, to facilitate the placement of the plate body. However, the present application does not limit this. In other embodiments of the present application, the plate body can also be other columnar structures, depending on the specific situation.
[0074] It should be noted that, in this embodiment, the light-dimming part can scatter the light emitted by the light source assembly, so that the light emitted from different positions in the light source assembly is mixed on the optical path of the light emitted by the light source assembly to the incident surface of the light guide plate, so as to improve the uniformity of the light incident on the incident surface of the light guide plate; the light-dimming part can also increase the beam angle of the light emitted from different positions in the light source assembly, so as to increase the overlapping area of the light emitted from different positions in the light source assembly, and improve the uniformity of the light incident on different positions of the incident surface of the light guide plate.

Optionally, the scattering particles are evenly distributed in the accommodation space in the plate body, so as to further improve the mixing uniformity of the light emitted by the light source assembly when passing through the light-dimming part, thereby further improving the uniformity of the light incident on the incident surface of the light guide plate, and further improving the uniformity of the light-emitting surface of the light guide plate, alleviating the "lamp shadow" phenomenon when the display panel is displaying, and improving the display quality of the display panel.
[0076] Specifically, in the above embodiment, when the light-dimming part includes scattering particles arranged in the accommodation space in the plate body, the scattering effect of the scattering particles on the light is utilized to diffuse the light beam emitted by the light-emitting part, so that the light emitted by the light source assembly can be more fully mixed when passing through the light-dimming part, improving the uniformity of the light incident on the incident surface of the light guide plate, thereby improving the uniformity of the light-emitting surface of the light guide plate, alleviating the "lamp shadow" phenomenon when the display panel is displaying, and improving the display quality of the display panel.
