Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display panel, display device, and splicing display device. Background Technology

[0002] As display technology becomes increasingly prevalent in various fields such as production and daily life, the requirements for display technology are also becoming more and more stringent. For example, display devices are required to accurately adjust the display brightness according to changes in ambient brightness based on the customer's viewing needs, thereby reducing visual fatigue and improving comfort in bright or dark environments. Summary of the Invention

[0003] In view of the above, this application provides a display panel and a display device, the solutions of which are as follows:

[0004] In a first aspect, this application provides a display panel, the display panel comprising:

[0005] A first substrate and a second substrate arranged opposite to each other;

[0006] A light-shielding structure is located on the side of the first substrate facing the second substrate, and a photosensitive structure is located on the side of the second substrate facing the first substrate; the light-shielding structure includes an opening along a first direction, the opening exposing the photosensitive structure, and the first direction is perpendicular to the plane of the display panel;

[0007] A dimming structure is located between a first substrate and a second substrate, and the dimming structure is located on the side of the photosensitive structure opposite to the second substrate, and along the first direction, the projection of the dimming structure covers at least a portion of the projection of the photosensitive structure.

[0008] Secondly, this application also provides a display device, which includes the aforementioned display panel.

[0009] Compared with related technologies, the beneficial effects of the technical solution of this application are as follows:

[0010] The display panel includes a first substrate, a second substrate, a light-shielding structure located on the side of the first substrate facing the second substrate, a photosensitive structure located on the side of the second substrate facing the first substrate, and a dimming structure located between the first substrate and the second substrate. The light-shielding structure includes an opening perpendicular to the plane of the display panel, exposing the photosensitive structure, and the projection of the dimming structure covers at least a portion of the projection of the photosensitive structure. Therefore, the opening of the light-shielding structure exposes the photosensitive structure below it in a direction perpendicular to the plane of the display panel, and the dimming structure can block at least a portion of the photosensitive structure below it. Thus, the dimming structure can suppress ambient light beams transmitted vertically to the photosensitive structure relative to the plane of the photosensitive structure, but does not suppress ambient light beams transmitted at an angle relative to the plane of the photosensitive structure. Therefore, the display panel can suppress ambient light beams transmitted vertically to the photosensitive structure by a dimming structure located above the photosensitive structure and blocking it vertically, while having weak or no suppression effect on ambient light beams transmitted at an angle. Therefore, this display panel can increase the proportion of ambient light beams transmitted to the photosensitive structure at a certain tilt angle, allowing the photosensitive structure to respond more effectively to ambient light beams transmitted to it at a specific tilt. Furthermore, by designing the relative vertical position of the dimming structure and the photosensitive structure below it, the intensity proportion of ambient light beams transmitted to the photosensitive structure at different directions can be adjusted, thereby achieving different display brightness adjustment modes suitable for a wider range of applications.

[0034] The embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely one area of ​​this application, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0035] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] As described in the background section, how to accurately adjust the display brightness based on the customer's viewing needs to adapt to changes in ambient brightness and improve comfort has become a key issue for those skilled in the art.

[0037] Typically, an ambient light sensor (ALS) is incorporated into a display device, with an opening in the light-shielding layer (BM) at a corresponding location. This allows the ALS to detect ambient light beams and adjust the display brightness accordingly. However, because the ALS cannot determine the incident direction of the detected ambient light beam, and the intensity of the beam perpendicularly incident upon it is relatively high, the ALS primarily adjusts the display brightness based on the intensity of the perpendicularly incident ambient light beam. Specifically... Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of a display panel based on related technologies. Figure 2 for Figure 1 The ALS response curve shown in the display panel is based on the ambient light beam transmitted to it. Figure 2The curves shown represent the intensity variations of the ambient light beam transmitted to the ALS along different transmission directions within a horizontal plane. This horizontal plane is perpendicular to the plane of the display panel. Figure 2 The horizontal axis represents the transmission direction of the ambient light beam (specifically, the angle between this angle and the positive viewing angle direction represented by the 0° position (the direction perpendicular to the plane of the display panel)), and the vertical axis represents the relative intensity of the ambient light beam transmitted to the ALS in different directions. According to Figure 1 and Figure 2 It can be seen that the ALS has the greatest response intensity at the normal viewing angle of the display panel, which is 0° on the horizontal axis. As the transmission direction gradually deviates from the normal viewing angle, the intensity gradually decreases. Therefore, the ALS responds more to the ambient light beam that is vertically transmitted to the ALS.

[0038] However, if the user's viewing position is not directly in front of the display panel, and is not in the normal viewing direction, but rather at an angle to the front of the display device, then the brightness adjustment will be inaccurate for the user. For example, in vehicle-mounted displays, the user's viewing position (driver and passenger) is at an angle to the front, so the brightness adjustment will be inaccurate for the user, affecting visibility and comfort.

[0039] Based on this, this application provides a display panel, such as Figure 3 As shown, Figure 3 This application provides a schematic diagram of a display panel structure, which includes a first substrate 100 and a second substrate 200 disposed opposite to each other. The display panel also includes a light-shielding structure 300 located on the side of the first substrate 100 facing the second substrate 200, a photosensitive structure 400 located on the side of the second substrate 200 facing the first substrate 100, and a dimming structure 500 located between the first substrate 100 and the second substrate 200. It should be noted that the aforementioned photosensitive structure 400 can be the ALS described in the background art, but this application does not limit it to this; it can also be other elements that can have photosensitive functions, depending on the specific circumstances.

[0040] The light-shielding structure 300 includes an opening 302. Along a first direction, the opening 302 exposes the photosensitive structure 400 and at least a portion of the dimming structure 500. Specifically, along the first direction, the projection of the opening 302 covers the projection of the photosensitive structure 400, and the projection of the opening 302 also covers at least a portion of the projection of the dimming structure 500. The first direction is perpendicular to the plane of the display panel, meaning it is parallel to the planes of the first substrate 100, the second substrate 200, and other film layers in the display panel. This first direction can also be referred to as the vertical direction, which is the thickness direction of the display panel. In other words, along a direction perpendicular to the plane of the display panel, the light-shielding structure 300 is located above the photosensitive structure 400, and the opening 302 is also located above the photosensitive structure 400. It should be noted that the light-shielding structure 300 is the commonly known black matrix (BM), which can block light beams transmitted through it. That is, ambient light beams can be transmitted to the photosensitive structure 400 through the opening 302 in the light-shielding structure 300.

[0041] It should be noted that, normally, along the first direction, the opening 302 of the light-shielding structure 300 exposes the photosensitive structure 400, that is, the projection of the opening 302 of the light-shielding structure 300 covers the projection of the photosensitive structure 400. However, this application does not limit this; along the first direction, the opening 302 of the light-shielding structure 300 may also at least partially expose the photosensitive structure 400, that is, the projection of the opening 302 of the light-shielding structure 300 at least partially covers the projection of the photosensitive structure 400.

[0042] The dimming structure 500 is located on the side of the photosensitive structure 400 opposite to the second substrate 200, and along the first direction, the projection of the dimming structure 500 covers at least a portion of the projection of the photosensitive structure 400; that is, along the first direction, the projection of the dimming structure 500 covers part or all of the projection of the photosensitive structure 400. In other words, along a direction perpendicular to the plane of the display panel, the opening 302 of the light-shielding structure 300 and the dimming structure 500 are both located above the photosensitive structure 400, allowing ambient light beams to be transmitted to the photosensitive structure 400 sequentially through the opening 302 and the dimming structure 500. It should be noted that the dimming structure 500 can suppress the transmission of ambient light beams through it; that is, the dimming structure 500 can suppress the transmission of ambient light beams to the photosensitive structure 400. It should also be noted that the statement that "along the first direction, the projection of the dimming structure 500 covers at least a portion of the projection of the photosensitive structure 400" refers to the projection of the dimming structure 500 covering at least a portion of the projection of the area with photosensitive function within the photosensitive structure 400.

[0043] As described above, along a direction perpendicular to the plane of the display panel, the opening 302 of the light-shielding structure 300 exposes the photosensitive structure 400 below it, and the dimming structure 500 can block at least a portion of the photosensitive structure 400 below it. Therefore, the dimming structure 500 can suppress ambient light beams propagating vertically relative to the plane of the photosensitive structure 400, but not ambient light beams propagating at a certain angle relative to the plane of the photosensitive structure 400. In other words, the dimming structure 500 has a stronger suppression effect on ambient light beams propagating vertically relative to the plane of the photosensitive structure 400, but a relatively weaker suppression effect on ambient light beams propagating at a certain angle relative to the plane of the photosensitive structure 400. Therefore, the display panel can suppress ambient light beams propagating vertically to the photosensitive structure 400 by using the dimming structure 500, which is located above the photosensitive structure 400 and at least partially blocks the photosensitive structure 400 in the vertical direction, while having a weaker or no suppression effect on ambient light beams propagating at a certain angle to the photosensitive structure 400. Therefore, this display panel increases the proportion of intensity of ambient light beams transmitted to the photosensitive structure 400 at a certain tilt angle, allowing the photosensitive structure 400 to respond more effectively to ambient light beams transmitted to it at a certain tilt direction. Consequently, when adjusting its brightness based on the dimming structure 500, the display panel can adjust the brightness more based on the ambient light beams transmitted at a certain tilt direction. This makes it more suitable for applications such as automotive displays where the viewing position is at an angle, improving visibility and comfort when adjusting the display brightness.

[0044] In addition, since the dimming structure 500 can suppress the ambient light beam transmitted to the photosensitive structure 400, the relative position of the dimming structure 500 and the photosensitive structure 400 located below it in the direction perpendicular to the plane of the display panel can adjust the intensity ratio of the ambient light beam transmitted to the photosensitive structure 400 in different directions, thereby realizing different display brightness adjustment modes and making it suitable for more application scenarios.

[0045] In one embodiment of this application, the light transmittance of the dimming structure 500 is a first transmittance, and the light transmittance of the portion of the light-shielding structure 300 excluding the opening 302 is a second transmittance. The first transmittance is greater than the second transmittance. That is, the light transmittance of the dimming structure 500 is greater than that of the light-shielding structure 300, so even though the dimming structure 500 can suppress the transmission of ambient light beams, it does not excessively block the transmitted ambient light beams. In the process of adjusting the display brightness in response to ambient light beams transmitted to it, the dimming structure 500 responds more to ambient light beams transmitted to it in a certain oblique direction, but also simultaneously responds to ambient light beams transmitted vertically to it. Therefore, the dimming structure 500 in the display panel can respond to ambient light beams transmitted to it from all directions in an all-round way, but responds more to ambient light beams transmitted to it in a certain oblique direction. Thus, the display panel can comprehensively and accurately adjust the display brightness based on the dimming structure 500. It should be noted that the light transmittance of the portion of the light-shielding structure 300 other than the opening 302 is the second transmittance, which refers to the light transmittance of the portion of the light-shielding structure 300 that can block the transmission of the light beam, that is, the light transmittance of the light-shielding structure 300 itself is the second transmittance.

[0046] In one embodiment of this application, such as Figure 4 As shown, Figure 4 This is a schematic diagram of a display panel structure provided in this application. A dimming structure 500 is disposed on the side of the first substrate 100 facing the second substrate 200. Along a first direction, the opening 302 of the light-shielding structure 300 exposes the dimming structure 500. Simultaneously, along a second direction, the width of the dimming structure 500 is a first width W1, and the width of the opening 302 of the light-shielding structure 300 is a second width W2, where the first width W1 is smaller than the second width W2. The second direction is parallel to the plane of the display panel, that is, parallel to the planes of the first substrate 100, the second substrate 200, and other film layers in the display panel.

[0047] Based on the above, such as Figure 5 As shown, the dimming structure 500 includes a first side 1 and a second side 2 opposite to each other along a second direction. Along the second direction, there is a gap between the first side 1 and / or the second side 2 of the dimming structure 500 and the edge of the opening 302, that is, there is a gap between the first side 1 of the dimming structure 500 and the edge of the opening 302 (e.g., Figure 6 (as shown), or there is a gap between the second side 2 of the dimming structure 500 and the edge of the opening 302 (as shown). Figure 7 As shown), or the first side 1 and the second side 2 of the dimming structure 500 both have gaps between them and the edge of the opening 302 (as shown). Figure 5(As shown). The ambient light beam transmitted to the photosensitive structure 400 through the opening 302 includes the ambient light beam transmitted to the photosensitive structure 400 through the dimming structure 500, and the ambient light beam transmitted to the photosensitive structure 400 through the aforementioned gap. That is, the ambient light beam transmitted to the photosensitive structure 400 through the opening 302 includes the ambient light beam transmitted to the photosensitive structure 400 through the dimming structure 500, and the ambient light beam transmitted to the photosensitive structure 400 through the gap between the first side 1 and / or the second side 2 of the dimming structure 500 and the opening 302.

[0048] As described above, along the second direction, there is a gap between the first side 1 and / or the second side 2 of the dimming structure 500 and the edge of the opening 302. Based on this, the projection of the dimming structure 500 covers at least a portion of the projection of the photosensitive structure 400, and there is a gap between the edge of at least one side of the dimming structure 500 along the second direction and the edge of the opening 302. Therefore, the ambient light beam transmitted to the photosensitive structure 400 through the opening 302 of the light-shielding structure 300 includes the ambient light beam transmitted to the photosensitive structure 400 through the dimming structure 500, and the ambient light beam transmitted to the photosensitive structure 400 through the gap between the first side 1 and / or the second side 2 of the dimming structure 500 and the edge of the opening 302. The ambient light beam transmitted to the photosensitive structure 400 through the dimming structure 500 is suppressed by the dimming structure 500. Therefore, the dimming structure 500 can suppress ambient light beams transmitted vertically to the photosensitive structure 400, while ambient light beams transmitted along a certain oblique direction through the gap between the dimming structure 500 and the edge of the opening 302 to the photosensitive structure 400 are not suppressed by the dimming structure 500. Consequently, the intensity proportion of the ambient light beams transmitted along the oblique direction to the photosensitive structure 400 increases, allowing the photosensitive structure 400 to respond more effectively to the ambient light beams transmitted along the oblique direction. Therefore, when adjusting its display brightness, the display panel can adjust its brightness more based on the ambient light beams transmitted along the oblique direction.

[0049] In one embodiment of this application, the following continues... Figure 5As shown, the opening 302 of the light-shielding structure 300 includes a third side 3 and a fourth side 4 opposite each other along the second direction. The third side 3 is closer to the first side 1 than the fourth side 4. That is, the arrangement order of the dimming structure 500 and the opening 302 opposite each other along the second direction can be the third side 3, the first side 1, the second side 2, and the fourth side 4, respectively. Along the second direction, there is a gap between the first side 1 of the dimming structure 500 and the third side 3 of the opening 302, and a gap between the second side 2 of the dimming structure 500 and the fourth side 4 of the opening 302. Furthermore, along the second direction, the distance between the first side 1 and the third side 3 is a first distance, and the distance between the second side 2 and the fourth side 4 is a second distance; the first distance and the second distance are equal. In other words, along the direction perpendicular to the plane of the display panel, the opening 302 of the light-shielding structure 300 exposes the dimming structure 500, or in other words, the dimming structure 500 is exposed in the opening 302 of the light-shielding structure 300. Furthermore, along the second horizontal direction, the gap between the edge of the dimming structure 500 and the edge of the opening 302 is equal, that is, the dimming structure 500 is exposed in the opening 302 of the light-shielding structure 300, and along the second direction, the dimming structure 500 is also symmetrically arranged with respect to the opening 302.

[0050] Based on the above, the dimming structure 500 responds to the ambient light beam transmitted onto it according to the response curve as follows: Figure 8 As shown, Figure 8 The vertical axis represents the illuminance distribution ratio of ambient light beams transmitted to the photosensitive structure 400 along different directions (i.e., the intensity proportion of ambient light beams transmitted to the photosensitive structure 400 along different directions out of all ambient light beams transmitted to the photosensitive structure 400). The horizontal axis represents the angle between the transmission direction of the ambient light beams transmitted to the photosensitive structure 400, which is perpendicular to the plane of the photosensitive structure 400 and lies in the plane of the second direction, and the vertical axis of the plane of the photosensitive structure 400. The 0° position on the horizontal axis represents the direction of the positive viewing angle of the display panel, which is also the angle between the transmission direction of the ambient light beams perpendicular to the photosensitive structure 400 and the axial direction of the plane of the photosensitive structure 400. Figure 8As can be seen, the 0° position of the curve represents the ambient light beam transmitted vertically to the photosensitive structure 400. Due to the suppression effect of the dimming structure 500, its intensity is low. Curve part 1 represents the ambient light beam with a transmission direction between 0° and 30° (excluding 0°). As the angle between the transmission direction and the axial direction of the plane where the photosensitive structure 400 is located gradually increases, the suppression effect of the dimming structure 500 gradually decreases, and the intensity gradually increases. Curve part 2 represents the ambient light beam transmitted to the photosensitive structure 400 through the gap between the dimming structure 500 and the opening 302. This part of the ambient light beam is directly transmitted to the photosensitive structure 400 and has the greatest intensity. Curve part 3 represents the ambient light beam with a more inclined transmission direction than the ambient light beam represented by curve part 2. As the angle between this part of the ambient light beam and the axial direction of the plane where the photosensitive structure 400 is located gradually increases, it is blocked by the light-blocking structure 300, and its intensity gradually decreases.

[0051] Therefore, due to the presence of the dimming structure 500, the illuminance ratio, or intensity proportion, of the ambient light beam transmitted to the photosensitive structure 400 in each transmission direction varies depending on the transmission direction. Specifically, this is related to the angle between the ambient light beam and the vertical axis of the plane containing the photosensitive structure 400. Furthermore, when the dimming structure 500 is symmetrically arranged with respect to the opening 302 along the second direction, the response curve of the dimming structure 500 also exhibits symmetry. That is, the intensity proportion of the ambient light beam transmitted to the photosensitive structure 400 in each transmission direction changes symmetrically as the dimming structure 500 and the opening 302 are symmetrically arranged along the second direction. Therefore, the dimming structure 500 can adjust the intensity proportion of the ambient light beam transmitted to the photosensitive structure 400 in different directions within the total ambient light beam transmitted to the photosensitive structure 400, and it can also adjust the way the intensity proportion of the ambient light beam transmitted to the photosensitive structure 400 changes in different directions. This allows for the flexibility of adjusting the display brightness based on the brightness of the ambient light beam (i.e., ambient brightness), making it highly practical.

[0052] In one embodiment of this application, such as Figure 9 and Figure 10 As shown above, Figure 5 for Figure 9 A sectional view along AA1, Figure 10 for Figure 9Along the cross-sectional view of BB1, along the third direction, the width of the dimming structure 500 is the third width W3, and the width of the opening 302 is the fourth width W4, with the third width W3 equal to the fourth width W4. That is, along the third direction, the width of the dimming structure 500 can be equal to the width of the opening 302 of the light-shielding structure 300. In other words, the opposite sides of the dimming structure 500 along the third direction coincide with the edge of the opening 302. At this time, the portion of the projection of the dimming structure 500 along the first direction along the third direction coincides with the projection of the opening 302 along the first direction. Since the opening 302 of the light-shielding structure 300 exposes the photosensitive structure 400, if the portion of the projection of the dimming structure 500 along the first direction along the third direction coincides with the projection of the opening 302 along the first direction, then the portion of the projection of the dimming structure 500 along the first direction along the third direction covers the projection of the photosensitive structure 400 along the first direction. Based on this, the ambient light beam transmitted to the photosensitive structure 400, within the plane perpendicular to the photosensitive structure 400 and within the plane of the second direction, is transmitted to the photosensitive structure 400 via the dimming structure 500. The third direction is parallel to the plane of the display panel and intersects the second direction; that is, both the third and second directions are parallel to the plane of the display panel, but the third direction differs from the second direction; for example, the third direction can be perpendicular to the second direction.

[0053] Specifically, such as Figure 11 As shown, Figure 11 The dimming structure 500 is based on the response curve formed by the ambient light beam transmitted onto it. Figure 11 The vertical axis represents the illuminance distribution ratio of ambient light beams transmitted to the photosensitive structure 400 along different directions. The horizontal axis represents the angle between the transmission direction of the ambient light beams transmitted to the photosensitive structure 400 and the vertical axis of the plane containing the photosensitive structure 400, perpendicular to the plane containing the photosensitive structure 400. The 0° position on the horizontal axis also represents the direction of the positive viewing angle, i.e., the angle between the transmission direction of the ambient light beams transmitted perpendicularly to the photosensitive structure 400 and the vertical axis of the plane containing the photosensitive structure 400. Figure 11 It can be seen that, since the ambient light beam transmitted to the photosensitive structure 400 is perpendicular to the plane where the photosensitive structure 400 is located, and all ambient light beams in the third direction plane are transmitted to the photosensitive structure 400 via the dimming structure 500, therefore... Figure 11Curve 1 represents the ambient light beam whose transmission direction is within a certain angle (e.g., -50° to 50°) relative to the vertical axis of the plane containing the photosensitive structure 400. This portion of the ambient light beam is not blocked by the light-blocking structure 300 and is entirely transmitted to the photosensitive structure 400 via the dimming structure 500, exhibiting the highest intensity. Curve 2, on the other hand, represents an ambient light beam whose transmission direction has a larger angle relative to the vertical axis of the plane containing the photosensitive structure 400. This portion is blocked by the light-blocking structure 300, and only a portion is transmitted to the photosensitive structure 400. Therefore, the illuminance distribution of the ambient light beam represented by curve 2 is relatively smaller and decreases as the tilt of the transmitted beam increases.

[0054] As described above, since the portion of the projection of the dimming structure 500 along the first direction along the third direction covers the projection of the photosensitive structure 400 along the first direction, the dimming structure 500 does not adjust the ambient light beam transmitted to the photosensitive structure 400 perpendicular to the plane where the photosensitive structure 400 is located and within the plane in the third direction. Therefore, the display panel can achieve targeted adjustment of the intensity ratio of a certain portion of the ambient light beam transmitted to the photosensitive structure 400 by setting the relative positional relationship between the dimming structure 500 and the edge of the opening 302, so as to more accurately adjust the display brightness according to user needs.

[0055] It should be understood that, for the display panel described in this application, at least one of the two sides of the dimming structure 500 along the third direction may have a gap between it and the edge of the opening 302, so that the photosensitive structure 400 can respond to more ambient light beams transmitted to it along the tilt direction, thereby meeting the brightness adjustment needs of more observation positions that deviate from the normal viewing angle direction and adapting to more application scenarios.

[0056] In one embodiment of this application, such as Figure 5 As shown, along the first direction, the geometric centers of the dimming structure 500 and the photosensitive structure 400 are located on the same straight line, and along the first direction, the projection of the dimming structure 500 covers the projection of the photosensitive structure 400. That is, along the first direction, the projection of the dimming structure 500 covers the projection of the photosensitive structure 400, and their geometric centers coincide. Therefore, the dimming structure 500 is symmetrically arranged relative to the photosensitive structure 400, so that the response curve of the photosensitive structure 400 to the ambient light beam transmitted to it can be symmetrical with respect to the positive viewing angle (i.e., at the 0° position of the sensing curve), such as... Figure 8 and Figure 11As shown, the relative positional relationship between the dimming structure 500 and the photosensitive structure 400 can also affect the response curve of the photosensitive structure 400, that is, affect the illuminance distribution ratio of the ambient light beams transmitted to the photosensitive structure 400 along different directions, thereby affecting the response degree of the photosensitive structure 400 to the ambient light beams transmitted to it along different directions, and thus changing the way the display brightness is adjusted.

[0057] Furthermore, since the response curve of the photosensitive structure 400 to the ambient light beam transmitted to it is symmetrical with respect to the viewing angle, it better conforms to the usual situation of display brightness adjustment. Therefore, in this embodiment, along the first direction, the geometric centers of the dimming structure 500 and the photosensitive structure 400 are located on the same straight line, and the projection of the dimming structure 500 covers the projection of the photosensitive structure 400. However, this application is not limited in its comparison and depends on the specific circumstances.

[0058] In one embodiment of this application, such as Figure 12 As shown, along the first direction, the distance between the dimming structure 500 and the photosensitive structure 400 is the third distance L1, that is, along the vertical direction, the distance between the dimming structure 500 and the photosensitive structure 400 is the third distance L1. Along the second direction, the distance between the dimming structure 500 and the edge of the opening 302 is the fourth distance L2, with a first width of W1 and a second width of W2. It should be noted that W2 - W1 ≥ L2, and L2 = L1(tanR2 - tanR1).

[0059] Wherein, the distance between at least one of the first side 1 and the second side 2 of the dimming structure 500 and the edge of the opening 302 is the fourth distance L2, and the light beam transmitted to the photosensitive structure 400 through the gap between the dimming structure 500 and the edge of the opening 302 is the first angle R1 between the transmission direction of the light beam transmitted to the photosensitive structure 400 through the first side 1 or the second side 2 of the dimming structure 500 and the first direction, and the angle between the transmission direction of the light beam transmitted to the photosensitive structure 400 through the edge of the opening 302 and the first direction is the second angle R2, where R1 < R2.

[0060] Specifically, such as Figure 12As shown, the dimming structure 500 includes a first side 1 and a second side 2 opposite to each other along a second direction. The opening 302 includes a third side 3 and a fourth side 4 opposite to each other along a second direction. The first side 1 and the second side 2 are located between the third side 3 and the fourth side 4, and the third side 3, the first side 1, the second side 2, and the fourth side 4 are arranged sequentially along the second direction. Along the first direction, the distance between the dimming structure 500 and the photosensitive structure 400 is L1. Along the second direction, the distance between the first side 1 and the third side 3 and / or the distance between the second side 2 and the fourth side 4 is L2, and the width of the dimming structure 500 is W1, the width of the opening 302 is W2, and W2-W1≥L2. Specifically, if there are gaps between the first side 1 and the second side 2 of the dimming structure 500 and the edge of the opening 302, and W2-W1>L2, and the gaps are equal, then W2-W1=2L2; if either the first side 1 or the second side 2 of the dimming structure 500 coincides with the edge of the opening 302, then W2-W1=L2. Based on this, continuing as shown in the figure, L1tanR1=L3, L1tanR2=L4, L3-L4=L2, so L2=L1(tanR2-tanR1).

[0061] It should be noted that if the angle between the transmission direction of the ambient light beam transmitted to the photosensitive structure 400 and the vertical axis of the plane where the photosensitive structure 400 is located is less than or equal to the first angle R1, then that portion of the ambient light beam will be transmitted to the photosensitive structure 400 via the dimming structure 500, i.e., as shown below. Figure 8 The angle range of the curve portion 1 shown; if the angle between the transmission direction and the axis of the plane where the photosensitive structure 400 is located is greater than the first angle R1 and less than or equal to the second angle R2, then this portion of the ambient light beam is transmitted to the photosensitive structure 400 through the gap between the dimming structure 500 and the opening 302, that is, corresponding to... Figure 8 The angle range of curve portion 2 shown. Based on this, it can be seen that the transmission direction of the ambient light beam transmitted from the dimming structure 500 to its photosensitive structure 400 through the size of the dimming structure 500 and the opening 302, as well as the size of the gap between them, can be precisely controlled and adjusted. This allows for control of the response curve of the photosensitive structure 400, thereby achieving flexible control over the adjustment method of the display brightness.

[0062] In one embodiment of this application, such as Figure 9As shown, the dimming structure 500 includes at least one sub-dimming structure 502 arranged along a second direction, and the light transmittance of the sub-dimming structure 502 is a third transmittance. Specifically, the light transmittance of the dimming structure 500 is a first transmittance, and the light transmittance of the portion of the light-shielding structure 300 excluding the opening 302 is a second transmittance. The first transmittance is greater than the second transmittance, and the third transmittance is not less than the second transmittance. That is, the dimming structure 500 may include at least one sub-dimming structure 502 along the second direction, and based on the premise that the light transmittance of the dimming structure 500 is greater than the light transmittance of the light-shielding structure 300, the light transmittance of the sub-dimming structure 502 is greater than the light transmittance of the light-shielding structure 300, or the light transmittance of the sub-dimming structure 502 is equal to the light transmittance of the light-shielding structure 300. Therefore, the dimming structure 500 may include sub-dimming structures 502 with light transmittance greater than and / or equal to the light transmittance of the light-shielding structure 300, which can be flexibly configured. Furthermore, the sub-dimming structure 502 in the dimming structure 500, whose light transmittance is equal to that of the light-shielding structure 300, can be formed synchronously with the light-shielding structure 300, simplifying the manufacturing process.

[0063] In one embodiment of this application, such as Figure 9 As shown, the dimming structure 500 includes one sub-dimming structure 502. Along the second direction, the width of the sub-dimming structure 502 is a fifth width W5, which is equal to the first width W1, and its third transmittance is equal to the first transmittance. That is, when the dimming structure 500 includes one sub-dimming structure 502, the light transmittance of the sub-dimming structure 502 is equal to the first transmittance and greater than the light transmittance of the light-shielding structure 300.

[0064] In one embodiment of this application, such as Figure 13 As shown, Figure 13 This is a schematic diagram of the dimming structure 500. The dimming structure 500 includes at least two sub-dimming structures 502, with gaps between adjacent sub-dimming structures 502. Along the second direction, the width of each sub-dimming structure 502 is a fifth width W5, and the width of the photosensitive structure 400 is a sixth width W6, where the fifth width W5 is smaller than the sixth width W6. Specifically, along the second direction, the sum of the widths of the at least two sub-dimming structures 502 and the widths of the gaps between adjacent sub-dimming structures 502 equals a first width W1. That is, if the dimming structure 500 includes at least two sub-dimming structures 502 arranged sequentially along the second direction, the width of the dimming structure, i.e., the first width W1, is equal to the sum of the widths W5 of the multiple sub-dimming structures 502 and the gaps between adjacent sub-dimming structures 502. It should be noted that... Figure 13 This is merely a schematic diagram of the dimming structure 500, and is not a limitation on the dimming structure 500 or the relative size relationship between the dimming structure 500 and the photosensitive structure 400. The specifics depend on the circumstances.

[0065] As described above, if the dimming structure 500 includes at least two sub-dimming structures 502 arranged sequentially along the second direction, then the width of the sub-dimming structure 502 is smaller than the width of the photosensitive structure 400 along the second direction. This ensures that the factors determining the light transmittance of the ambient light beam transmitted from the dimming structure 500 to the photosensitive structure 400 include the width of the dimming structure 500, the width of the sub-dimming structure 502, and the transmittance of the sub-dimming structure 502. In other words, the factors determining the transmittance of the dimming structure 500 for the ambient light beam transmitted through it include the width of the dimming structure 500, the width of the sub-dimming structure 502, and the transmittance of the sub-dimming structure 502. Therefore, the light transmittance of the dimming structure 500 can be adjusted through these multiple determining factors to achieve precise adjustment and a wider range of adjustment, making it highly practical.

[0066] In one embodiment of this application, the light transmittance of the sub-dimming structures 502 is equal, or the light transmittance of the sub-dimming structures 502 is not equal. That is, if the dimming structure 500 includes a plurality of sub-dimming structures 502 arranged along the second direction, the light transmittance of the plurality of sub-dimming structures 502 can be equal or not, and can be flexibly set.

[0067] In one embodiment of this application, the light transmittance of the sub-dimming structures 502 is equal. That is, if the dimming structure 500 includes a plurality of sub-dimming structures 502 arranged along the second direction, the light transmittance of the plurality of sub-dimming structures 502 is equal, so as to simplify the dimming structure 500 and thus simplify the manufacturing process.

[0068] Based on the above, in one embodiment of this application, such as Figure 13 As shown, the third transmittance is less than the first transmittance and greater than the second transmittance. That is, the light transmittance of the sub-dimming structure 502 is equal, and the light transmittance of the sub-dimming structure 502 is less than the light transmittance of the dimming structure 500 and greater than the light transmittance of the light-shielding structure 300.

[0069] In another embodiment of this application, such as Figure 14 As shown, Figure 14 This is a schematic diagram of the dimming structure 500. The third transmittance is equal to the first transmittance, meaning the light transmittance of the sub-dimming structure 502 is equal to the light transmittance of the light-shielding structure 300. It should be noted that, since the dimming structure 500 includes multiple sub-dimming structures 502 along the second direction, the width of the dimming structure 500 along the second direction is equal to the sum of the widths of the multiple sub-dimming structures 502 along the second direction and the width of the gaps between adjacent dimming structures 500. Therefore, even if the light transmittance of the sub-dimming structure 502 is equal to the light transmittance of the light-shielding structure 300, the light transmittance of the dimming structure 500 is still greater than the light transmittance of the light-shielding structure 300.

[0070] In one embodiment of this application, such as Figure 15 As shown, Figure 15 The diagram shows the structure of the dimming structure 500. The transmittance of the sub-dimming structures 502 is not equal. That is, when the dimming structure 500 includes multiple sub-dimming structures 502 arranged sequentially along the second direction, the light transmittance of the sub-dimming structures 502 is not equal, so that the light transmittance of the dimming structure 500 can be adjusted more precisely and within a wider range.

[0071] Based on the above, in one embodiment of this application, the light transmittance of at least one sub-dimming structure 502 is equal to the second transmittance, and the light transmittance of the remaining sub-dimming structures 502 is less than the first transmittance and greater than the second transmittance. That is, among the aforementioned plurality of sub-dimming structures 502, the light transmittance of at least one sub-dimming structure 502 is equal to the light transmittance of the light-shielding structure 300, and the light transmittance of the remaining sub-dimming structures 502 is less than the light transmittance of the dimming structure 500 and greater than the light transmittance of the light-shielding structure 300. It should be noted that the light transmittance of the remaining sub-dimming structures 502 may be equal or unequal. That is, in this embodiment, apart from the sub-dimming structure 502 with the same light transmittance as the light-shielding structure 300, the light transmittance of the remaining sub-dimming structures 502 of the dimming structure 500 may be equal or unequal, provided that it is less than the first transmittance and greater than the second transmittance.

[0072] In another embodiment of this application, if the light transmittance of the plurality of sub-dimming structures 502 in the dimming structure 500 is not equal, then the light transmittance of the sub-dimming structures 502 can be less than the first transmittance and greater than the second transmittance, and the light transmittance of the sub-dimming structures 502 is not equal.

[0073] It should be noted that the light transmittance of the aforementioned sub-tuning structures 502 is not equal. This can mean that the light transmittance of all sub-tuning structures 502 is not equal, or that the light transmittance of at least one sub-tuning structure 502 is not equal to the light transmittance of the other sub-tuning structures 502. This application does not limit this, and it depends on the specific circumstances.

[0074] It should also be noted that the material of the light-shielding structure 300 in the display panel is usually pure black ink. Therefore, if the light transmittance of the sub-dimming structure 502 in the dimming structure 500 is equal to the light transmittance of the light-shielding structure 300, then the material of the sub-dimming structure 502 can be pure black ink. However, if the light transmittance of the sub-dimming structure 502 is greater than that of the light-shielding structure 300, then the material of the sub-dimming structure 502 can be a material with a relatively higher light transmittance than pure black ink, such as semi-transparent ink. However, this application does not limit the materials of the sub-dimming structures 502 with different light transmittances mentioned above; it depends on the specific circumstances.

[0075] In one embodiment of this application, such as Figure 16 As shown, Figure 16 The diagram shows the structure of the dimming structure 500. Along the second direction, the widths W5 of the sub-dimming structures 502 are equal, and the widths W7 of the gaps between adjacent sub-dimming structures 502 are equal. This makes the distribution of the sub-dimming structures 502 in the dimming structure 500 regular, which can simplify the dimming structure 500 and thus simplify the manufacturing process.

[0076] In one embodiment of this application, such as Figure 17 As shown, Figure 17 This application provides a schematic diagram of the structure of a display panel. A dimming structure 500 is located between a light-shielding structure 300 and a photosensitive structure 400, and is disposed on the photosensitive structure 400, specifically on the side of the photosensitive structure 400 facing the light-shielding structure 300. The dimming structure 500 includes a side surface 504 extending from the photosensitive structure 400 toward an opening 302, and the side surface 504 includes at least an inclined side surface 506 extending obliquely toward the opening 302. In other words, the dimming structure 500 may include a bottom surface 508, which is the side of the dimming structure 500 facing the photosensitive structure 400, and the dimming structure 500 also includes a side surface 504 extending from the bottom surface 508 toward the opening 302, at least a portion of which is the inclined side surface 506 extending obliquely toward the opening 302. Meanwhile, along the second direction, the distance between the portion of the aforementioned inclined side 506 closer to the opening 302 and the edge of the opening 302 is greater. That is, the inclined side 506 extending inclinedly toward the opening 302 is an inclined side 506 extending inclinedly toward the interior of the opening 302 along the second direction. Furthermore, along the first direction, at least a portion of the inclined side 506 is exposed in the opening 302 of the light-shielding structure 300; that is, at least a portion of the inclined side 506 extending inclinedly toward the opening 302 of the dimming structure 500 is exposed in the opening 302. The second direction is parallel to the plane of the display panel.

[0077] Along the first direction, the projection of at least a portion of the inclined side 506 exposed in the opening 302 of the light-shielding structure 300 covers at least a portion of the projection of the photosensitive structure 400. That is, along the first direction, the projection of the portion of the inclined side 506 exposed in the opening 302 covers at least a portion of the projection of the photosensitive structure 400, so the ambient light beam transmitted to the photosensitive structure 400 through the opening 302 includes the ambient light beam refracted to the photosensitive structure 400 through the at least portion of the inclined side 506 exposed in the opening 302.

[0078] The reflectivity of the light beam refracted to the photosensitive structure 400 via at least a portion exposed in the opening 302 through the inclined side 506 is directly proportional to its incident angle θ when it reaches the inclined side 506. It should be noted that the inclined side 506 is an inclined side extending inward from the side where its bottom surface 508 is located, towards the plane containing the opening 302 of the light-shielding structure 300. In other words, the inclined side 506 is an inclined side extending inward from the side of the dimming structure 500 towards the photosensitive structure 400, towards the plane containing the opening 302 of the light-shielding structure 300. Therefore, the incident angle θ of the ambient light beam transmitted to the photosensitive structure 400 via at least a portion exposed in the opening 302 through the inclined side 506 varies depending on the angle between the transmission direction and the axis of the plane containing the photosensitive structure 400. Specifically, the larger the angle between the transmission direction and the axis of the plane containing the photosensitive structure 400, the smaller the incident angle θ. The larger the incident angle θ, the greater the reflectivity; the smaller the incident angle θ, the smaller the reflectivity. And when the incident angle θ is less than a certain value, the change in reflectivity will tend to stabilize.

[0079] according to Figure 17 It is known that the larger the angle between the transmission direction and the axis of the ambient light beam transmitted sequentially to the photosensitive structure 400 through the opening 302 and the inclined side 506, the smaller the incident angle θ to the inclined side 506, and the lower the reflectivity. In other words, the more inclined the transmission direction, the smaller the incident angle, and the lower the reflectivity. When the incident angle is less than a certain value, the reflectivity tends to stabilize. Therefore, the inclined side 506 can suppress the ambient light beam transmitted vertically to the photosensitive structure 400. As the angle between the transmission direction of the ambient light beam transmitted to the photosensitive structure 400 and the axis of the plane containing the photosensitive structure 400 gradually increases, the suppression effect gradually decreases until it stabilizes. Therefore, the larger the angle between the transmission direction and the axis of the plane containing the photosensitive structure 400, the lower the reflectivity of the ambient light beam transmitted to the photosensitive structure 400 through the inclined side 506, and when the incident angle is small, the reflectivity tends to stabilize and no longer increases. In other words, in the ambient light beam transmitted to the photosensitive structure 400 via the inclined side 506, as the angle between the transmission direction and the axis of the plane where the photosensitive structure 400 is located gradually increases, the proportion of illuminance distribution in the entire ambient light beam transmitted to the photosensitive structure 400 gradually increases, and after increasing to a certain value, it tends to stabilize and no longer increases. Based on this, the response curve of the photosensitive structure 400 can be as follows: Figure 8As shown, curve 1 represents the gradual increase in reflectivity as the angle between the transmission direction and the vertical axis of the plane where the photosensitive structure 400 is located gradually increases, resulting in a gradually increasing intensity proportion in all ambient light beams transmitted to the photosensitive structure 400; curve 2 represents the situation where, when the angle between the transmission direction and the axis of the plane where the photosensitive structure 400 is located is large, the incident angle of the ambient light beam is small, the reflectivity tends to stabilize, and its intensity proportion no longer increases, also tending to stabilize; curve 3 represents the situation where, when the angle between the transmission direction and the vertical axis of the plane where the photosensitive structure 400 is located further increases, the ambient light beam will be blocked by the light-blocking structure 300, resulting in a decrease in the illuminance ratio.

[0080] Therefore, the dimming structure 500 can also increase the intensity proportion of the ambient light beam transmitted to the photosensitive structure 400 along a certain tilt direction, thereby enabling the photosensitive structure 400 to respond more to the ambient light beam transmitted to it along a certain tilt direction. Thus, when the display panel adjusts its brightness based on this dimming structure 500, it can adjust the brightness more based on the ambient light beam transmitted along a certain tilt direction.

[0081] In one embodiment of this application, such as Figure 18 As shown, Figure 18 This application provides a schematic diagram of the structure of a display panel. The inclined side 506 includes a first inclined side 510 and a second inclined side 512 opposite to each other along a second direction, intersecting on the side facing the opening 302. Meanwhile, the opening 302 includes a third side 3 and a fourth side 4 opposite to each other along the second direction, with the third side 3 closer to the first inclined side 510 than the fourth side 4. Furthermore, along the second direction, the distance between the first inclined side 510 and the third side 3 is equal to the distance between the second inclined side 512 and the fourth side 4. In other words, the inclined side 506 of the dimming structure 500 may include a first inclined side 510 and a second inclined side 512 opposite to each other along the second direction, and the first inclined side 510 and the second inclined side 512 are symmetrically arranged with respect to the opening 302. For example, the cross-sectional shape of the dimming structure 500 in the plane perpendicular to the plane containing the photosensitive structure 400 and within the plane of the second direction can be an isosceles triangle.

[0082] Based on the above, the first inclined side surface 510 and the second inclined side surface 512 have the same effect on the ambient light beam transmitted through them, so as... Figure 8As shown, the response curve of the photosensitive structure 400 based on the ambient light beam transmitted to it can be a response curve symmetrical with respect to the 0° viewing angle. That is, the relative positional relationship between the first tilted side 510 and the second tilted side 512, and their positional relationship relative to the opening 302, can affect the response curve of the photosensitive structure 400 based on the ambient light beam transmitted to it, and thus affect the intensity ratio of different transmission directions in the ambient light beam transmitted to the photosensitive structure 400. Therefore, this display panel can change the adjustment method when adjusting the display brightness based on ambient brightness by adjusting the tilted side 506 in the dimming structure 500, making it suitable for more application scenarios and highly practical.

[0083] It should be noted that, Figure 8 and Figure 11 The response curve of the photosensitive structure 400 is the response curve under ideal conditions. However, in actual conditions... Figure 8 The response curve shown can be as follows Figure 19 As shown in curve 1, curves 2 and 3 represent the upper and lower limits of the response curve under ideal conditions, respectively. Figure 11 The response curve shown can be as follows Figure 20 As shown in curve 1, curves 2 and 3 represent the upper and lower limits of the response curve under ideal conditions, respectively.

[0084] In one embodiment of this application, along the second direction, the width of the projection of the inclined side 506 along the first direction is a seventh width W7, and the width of the opening 302 is a second width W2. Wherein, the seventh width W7 is smaller than the second width W2 (e.g., ...). Figure 21 (as shown), or, the seventh width W7 is not less than the second width W2 (as shown). Figure 22 (As shown). That is, the width of the projection of the inclined side 506 along the first direction can be less than the width of the opening 302, or it can be no less than the width of the opening 302. Specifically, the width of the projection of the inclined side 506 along the first direction is less than the width of the opening 302, the inclined side 506 can be completely exposed in the opening 302, and there is a gap between it and the edge of the opening 302 along the second direction. Based on this, the ambient light beam transmitted to the photosensitive structure 400 through the opening 302 includes the ambient light beam transmitted to the photosensitive structure 400 through the inclined side 506, and the ambient light beam transmitted to the photosensitive structure 400 through the aforementioned gap. The width of the projection of the inclined side 506 along the first direction is no less than the width of the opening 302, that is, the inclined side 506 coincides with the edge of the opening 302 along the second direction. Based on this, the ambient light beam transmitted to the photosensitive structure 400 through the opening 302 includes the ambient light beam transmitted to the photosensitive structure 400 through the inclined side 506.

[0085] In one embodiment of this application, the dimming structure 500 can be a transparent conical prism, which includes a side extending from the photosensitive structure 400 toward the opening 302, and the side of the conical prism includes an inclined side 506 extending obliquely toward the opening 302. For example, the dimming structure 500 can be a prism column including an isosceles triangle with a cross-section along the second plane, etc., and this application does not limit it.

[0086] It should be noted that in the above embodiment, the inclined side 506 of the dimming structure 500 is inclined inward along the second direction toward the plane where the opening 302 is located. Similarly, the inclined side 506 of the dimming structure 500 may also be inclined inward along a third direction toward the plane where the opening 302 is located. Alternatively, the dimming structure 500 may include an inclined side 506 that is inclined in the second direction toward the plane where the opening 302 is located, and an inclined side 506 that is inclined in a third direction toward the plane where the opening 302 is located. This application does not limit this, and it depends on the specific circumstances.

[0087] In one embodiment of this application, such as Figure 23 As shown, the shape of the projection of the opening 302 of the light-shielding structure 300 along the first direction can be circular, that is, the opening 302 of the light-shielding structure 300 corresponding to the photosensitive structure 400 can be a circular opening 302, so as to ensure the anisotropic consistency of the ambient light beam transmitted to the photosensitive structure 400, thereby helping to ensure the accuracy of brightness adjustment.

[0088] This application also provides a display device, such as... Figure 24 As shown, the display device 01 includes the display panel 001 described in any of the above embodiments.

[0089] In summary, this application provides a display panel and a display device. The display panel includes a first substrate, a second substrate, a light-shielding structure located on the side of the first substrate facing the second substrate, a photosensitive structure located on the side of the second substrate facing the first substrate, and a dimming structure located between the first substrate and the second substrate. The light-shielding structure includes an opening in a direction perpendicular to the plane of the display panel, the opening exposing the photosensitive structure, and the projection of the dimming structure covers at least a portion of the projection of the photosensitive structure. Therefore, in a direction perpendicular to the plane of the display panel, the opening of the light-shielding structure exposes the photosensitive structure below it, and the dimming structure can block at least a portion of the photosensitive structure below it. Thus, the dimming structure can suppress ambient light beams transmitted vertically to the photosensitive structure relative to the plane of the photosensitive structure, but does not suppress ambient light beams transmitted at an angle relative to the plane of the photosensitive structure. Therefore, this display panel can suppress ambient light beams transmitted vertically to the photosensitive structure through a dimming structure located above the photosensitive structure and blocking the photosensitive structure in a vertical direction, while the suppression of ambient light beams transmitted at an angle is weak or non-existent. Therefore, this display panel can increase the proportion of the intensity of the ambient light beam transmitted to the photosensitive structure at a certain tilt angle, so that the photosensitive structure can respond more to the ambient light beam transmitted to it at a certain tilt direction.
