Detailed Description
Features and exemplary embodiments of various aspects of the present application will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples thereof.
It should be noted that, in this document, relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
Referring to fig. 1 to 3, the conventional display panel includes a first display area AA1, a transparent display area AA3, and a second display area AA2 disposed between the first display area AA1 and the transparent display area AA3, the display panel 100' includes a light-emitting layer 2', and a first shielding layer 3' and a second shielding layer 4' disposed on one side of the light-emitting layer 2', and the light-emitting layer 2' includes a first light-emitting portion 211' located in the first display area AA1, a second light-emitting portion 212' located in the second display area AA2, and a third light-emitting portion 213' located in the transparent display area AA 3. The first shielding layer 3' is located in the first display area AA1 and the second display area AA2, and has a plurality of openings thereon to expose the first light emitting portion 211' and the second light emitting portion 212', the second shielding layer 4' is located in the light transmissive display area AA3, and an orthographic projection of the second shielding layer 4' on the light emitting layer 2' is disposed around the third light emitting portion 213 '.
The light-shielding area in the unit area of the light-transmitting display area AA3 is smaller than the light-shielding area in the unit area of the first display area AA1, that is, the light transmittance of the light-transmitting display area AA3 is greater than that of the first display area AA1, so that the external ambient light can reach the light-sensing element arranged below the light-transmitting display area AA3 through the light-transmitting display area AA3, and the functions of shooting and the like are realized. It is understood that the driving circuit for driving the third light emitting portion 213' of the transparent display area AA3 is often disposed in the second display area AA2, so as to further reduce the light shielding area per unit area in the transparent display area AA3, and further increase the light transmittance of the transparent display area AA 3.
However, the inventor found that, since the light transmittance of the transparent display area AA3 is high, ambient light incident on the metal disposed below the transparent display area AA3 is reflected back, so that the reflectivity of the transparent display area AA3 is higher than that of the first display area AA 1. The design structure will increase the light-shielding area in the unit area of the second display area AA2, that is, the reflectivity of the second display area AA2 is smaller than the reflectivity of the first display area AA1, so that there is a sudden change between the reflectivity of the first display area AA1, the reflectivity of the second display area AA2 and the emissivity of the transparent display area AA3, which may cause a bright reflection line at the boundary area between the second display area AA2 and the first display area AA1 as well as the transparent display area AA3 when the display panel is turned on, resulting in uneven display of the display panel.
In order to solve the above problem, embodiments of the present application provide a display panel and a display device, which will be described in detail below with reference to fig. 4 to 14.
Referring to fig. 4 to 8, an embodiment of the present application provides a display panel, including a transparent display area AA3 and a first display area AA1 at least partially surrounding the transparent display area AA3, where a second display area AA2 is further disposed between the transparent display area AA3 and the first display area AA1, and a light transmittance of the transparent display area AA3 is greater than a light transmittance of the first display area AA1, where the display panel includes: a substrate 1; a light emitting layer 2 disposed on one side of the substrate 1, the light emitting layer 2 including a plurality of light emitting cells 21 and a pixel defining layer 22 for defining each of the light emitting cells 21, the plurality of light emitting cells 21 including a first light emitting portion 211 located in the first display area AA1 and a second light emitting portion 212 located in the second display area AA 2; the first shielding layer 3 is located in the first display area AA1 and the second display area AA2, and is disposed on a side of the light emitting layer 2 away from the substrate 1, the first shielding layer 3 is provided with a first light transmitting portion 31 and a second light transmitting portion 32, an orthographic projection of the first light transmitting portion 31 on the light emitting layer 2 is overlapped with the light emitting unit 21, the second light transmitting portion 32 is located in the second display area AA2, and an orthographic projection of the second light transmitting portion 32 on the substrate 1 is not overlapped with an orthographic projection of the second light emitting portion 212 on the substrate.
The display panel in the embodiment of the present application includes a first display area AA1, a second display area AA2, and a light-transmitting display area AA3, where a light transmittance of the light-transmitting display area AA3 is greater than a light transmittance of the first display area AA 1. The display panel comprises a substrate 1, a light emitting layer 2 and a first shielding layer 3 which are arranged in a stacked manner, the light emitting layer 2 comprises a plurality of light emitting units 21, the first shielding layer 3 is located in a first display area AA1 and a second display area AA2, the first shielding layer 3 is provided with a first light transmission part 31, the orthographic projection of the first light transmission part 31 on the light emitting layer 2 is overlapped with the light emitting units 21 to expose at least part of the first light emitting part 211 and the second light emitting part 212, and therefore image display of the first display area AA1 and the second display area AA2 is achieved. In order to realize the transition from the reflectivity of the first display area AA1 to the reflectivity of the light-transmitting display area AA3, the first shielding layer 3 further has a second light-transmitting portion 32, the second light-transmitting portion 32 is located in the second display area AA2, and the orthographic projection of the second light-transmitting portion 32 on the substrate 1 and the orthographic projection of the second light-emitting portion 212 on the substrate 1 do not overlap. The second transparent portion 32 is additionally arranged in the second display area AA2 compared with the first display area AA1, so that the reflectivity of the second display area AA2 is increased, the reflectivity of the second display area AA2 is between the reflectivity of the first display area AA1 and the reflectivity of the transparent display area AA3, the reflectivity of the first display area AA1, the reflectivity of the second display area AA2 and the reflectivity of the transparent display area AA3 are in gradient change, the problem of display unevenness of the display panel is improved, and the transitional display effect of the display panel is improved.
It can be understood that, by forming the second transparent portion 32 on the second display area AA2, the metal film layer in the area corresponding to the second transparent portion 32 is exposed, so as to increase the reflectivity of the second display area AA 2. Alternatively, the second light transmission portion 32 may be provided as a plurality of openings arranged at intervals, and an orthographic projection of each opening on the substrate 1 and an orthographic projection of each second light emitting portion 212 on the substrate 1 do not overlap, so that the difficulty in opening the second light transmission portion 32 is reduced by dividing the second light transmission portion 32 into a plurality of openings. The second transparent portion 32 may also be a stripe structure extending from the first display area AA1 to the transparent display area AA3, and an orthogonal projection of the stripe structure on the substrate 1 is set to avoid an orthogonal projection of each second light emitting portion 212 on the substrate 1, which may satisfy that the reflectivity of the second display area AA2 is between the reflectivity of the first display area AA1 and the reflectivity of the transparent display area AA 3.
Referring to fig. 4 to 6, in some optional embodiments, when the second light-transmitting portion 32 is provided with a plurality of openings arranged at intervals, the orthographic projection of the second light-transmitting portion 32 on the substrate 1 and the orthographic projection of the second light-emitting portion 212 on the substrate 1 do not overlap, specifically, the orthographic projection of the second light-transmitting portion 32 on the light-emitting layer 2 is located between two adjacent second light-emitting portions 212; and/or the orthographic projection of the second light transmitting portion 32 on the substrate 1 surrounds the orthographic projection of the second light emitting portion 212 on the substrate 1. That is, the orthographic projections of the plurality of openings on the light emitting layer 2 may be provided around at least a part of the second light emitting portions 212, may be positioned between two adjacent second light emitting portions 212, or may be provided partially around the second light emitting portions 212 and partially positioned between two adjacent second light emitting portions 212.
In some optional embodiments, the light emitting unit 21 further includes a third light emitting portion 213 located in the transmissive display area AA3, the display panel further includes a second shielding layer 4, the second shielding layer 4 is located in the transmissive display area AA3 and disposed on a side of the light emitting layer 2 away from the substrate 1, and the second shielding layer 4 includes a plurality of light shielding rings disposed around the third light emitting portions 213 and sleeved with each other. By disposing the second shielding layer 4 of the light-transmitting display area AA3 as a light-shielding ring surrounding the third light-emitting portion 213, compared with the case where all the areas of the first display area AA1 except the first light-shielding portion 31 cover the first shielding layer 3, the coverage area of the first shielding layer 3 is relatively reduced, thereby increasing the light transmittance of the light-transmitting display area AA 3. In addition, since the radius of the inner edge of the light shielding ring is larger than the radius of the outer edge of the third light emitting portion 213, the display luminance of the light transmissive display area AA3 can be increased, and the display effect of the display panel can be improved.
Optionally, the first shielding layer 3 and the second shielding layer 4 are disposed on the same layer and formed by synchronously evaporating the same black matrix material, so that the number of manufacturing steps of the display panel is reduced, and the manufacturing process is simplified.
Since the first shielding layer 3 in the first display area AA1 is disposed in the entire area except for the first light-shielding portion 31, and the projection of the second shielding layer 4 in the light-transmitting display area AA3 on the light-emitting layer 2 is disposed as a light-shielding ring disposed around the third light-emitting portion 213, the transition from the first display area AA1 to the light-transmitting display area AA3 is facilitated. In some alternative embodiments, the orthogonal projection of the second light-transmitting portion 32 near the first display area AA1 on the side of the light-emitting layer 2 is located between two adjacent second light-emitting portions 212, and the orthogonal projection of the second light-transmitting portion 32 near the light-transmitting display area AA3 on the side of the substrate 1 is disposed around the orthogonal projection of the second light-emitting portion 212 on the substrate 1. By opening the second light-transmitting portion 32 close to the first display area AA1 between two adjacent second light-emitting portions 212, the structure of the first shielding layer 3 close to the first display area AA1 is more similar to the structure of the first shielding layer 3 located in the first display area AA 1. Meanwhile, the orthographic projection of the second transparent part 32 close to the transparent display area AA3 on the light emitting layer 2 is arranged around the second light emitting part 212, so that the structure of the first shielding layer 3 close to the transparent display area AA3 is more similar to the structure of the second shielding layer 4 located in the transparent display area AA3, and the transitional display effect from the first display area AA1 to the transparent display area AA3 can be improved.
Referring to fig. 9 to 12, in order to further improve the transition display effect from the first display area AA1 to the transparent display area AA3, in some optional implementations, the area and/or density of the second transparent portion 32 gradually increases in the second display area AA2 along the direction from the first display area AA1 to the transparent display area AA 3. Since the reflectivity of the light-transmitting display area AA3 is greater than that of the first display area AA1, the area and/or the density of the second light-transmitting portion 32 is gradually increased, so that the proportion of the second light-transmitting portion 32 in the second display area AA2 per unit area is gradually increased along the direction from the first display area AA1 to the light-transmitting display area AA3, that is, the reflectivity of each sub-area in the second display area AA2 is gradually increased, and therefore the transition from the reflectivity of the first display area AA1 to the reflectivity of the light-transmitting display area AA3 can be better achieved.
Alternatively, the area and/or density of the second transparent portion 32 may be adjusted such that the reflectivity of the second display area AA2 on the side close to the first display area AA1 is equal to the reflectivity of the first display area AA1, and the reflectivity of the second display area AA2 on the side close to the transparent display area AA3 is equal to the reflectivity of the transparent display area AA3, so as to further achieve a smooth transition from the reflectivity of the first display area AA1 to the reflectivity of the transparent display area AA 3.
For convenience of describing the adjustment manner of the area and/or density of the second light transmission portion 32, the following description will be given by taking a case where the orthographic projection of the second light transmission portion 32 on the substrate 1 surrounds the orthographic projection of the second light emitting portion 212 on the substrate 1, and a case where the orthographic projection of the second light transmission portion 32 on the light emitting layer 2 is located between two adjacent second light emitting portions 212 as examples.
Referring to fig. 9 and 10, in some alternative embodiments, the second light-transmitting portion 32 includes a plurality of first sub light-transmitting portions 321, and an orthogonal projection of the first sub light-transmitting portions 321 on the substrate 1 surrounds an orthogonal projection of the second light-emitting portion 212 on the substrate 1; the area of the first sub light-transmitting portion 321 gradually increases along the direction of the first display area AA1 toward the light-transmitting display area AA 3. The size of the outer edge contour of each of the first sub light-transmitting portions 321 is gradually increased along the direction from the first display area AA1 to the light-transmitting display area AA3 when the size of the inner edge contour of each of the first sub light-transmitting portions 321 is the same, that is, the area of the first sub light-transmitting portion 321 in the unit area in the second display area AA2 is gradually increased, so that the reflectivity of each area in the second display area AA2 is gradually increased, and smooth transition from the reflectivity of the first display area AA1 to the reflectivity of the light-transmitting display area AA3 is realized through the second display area AA 2.
It can be understood that the orthographic projection of the first sub light-transmitting portion 321 on the substrate 1 around the orthographic projection of the second light-emitting portion 212 on the substrate 1 may include that the orthographic projection of the first sub light-transmitting portion 321 on the substrate 1 surrounds the orthographic projection of the second light-emitting portion 212 on the substrate 1 at intervals, that is, an inner edge contour of the orthographic projection of the first sub light-transmitting portion 321 on the substrate 1 is located at the periphery of an outer edge contour of the orthographic projection of the second light-emitting portion 212 on the substrate 1, and a certain preset distance is provided between the inner edge contour and the outer edge contour. Alternatively, the orthographic projection of the first sub light-transmitting portion 321 on the substrate 1 meets the orthographic projection of the second light-emitting portion 212 on the substrate 1, that is, the inner edge contour of the first sub light-transmitting portion 321 coincides with the outer edge contour of the second light-emitting portion 212.
Referring to fig. 9, to facilitate the preparation of the first sub light-transmitting portion 321, in some optional embodiments, a projection of the first sub light-transmitting portion 321 on the substrate 1 is a first projection, and a projection of the second light-emitting portion 212 corresponding to the first sub light-transmitting portion 321 on the substrate 1 is a second projection, where the first projection is adjacent to the second projection. The first projection and the second projection are adjacent, that is, the inner edge profile of the first sub light-transmitting portion 321 coincides with the outer edge profile of the corresponding second light-emitting portion 212, and because the orthogonal projection of the first light-transmitting portion 31 located in the second display area AA2 on the light-emitting layer 2 overlaps with the second light-emitting portion 212, the first light-transmitting portion 31 is connected to the first sub light-transmitting portion 321, so that the first light-transmitting portion 31 and the first sub light-transmitting portion 321 can be synchronously prepared and formed, thereby simplifying the preparation process.
In some optional embodiments, the first sub light-transmitting portion 321 has a ring shape, and a distance from an edge of the first projection away from the second projection to an edge of the first projection close to the second projection increases gradually along a direction from the first display area AA1 to the light-transmitting display area AA 3. The outer edge contour of the first sub light-transmitting portion 321 is the same as the outer edge contour of the second light-emitting portion 212, and thus the annular first sub light-transmitting portion 321 can be formed. The distance between the edge of the first projection far from the second projection and the edge of the first projection close to the second projection is the straight-line distance d between the outer edge contour of the first sub light-transmitting portion 321 and the outer edge contour of the corresponding second light-emitting portion 212. By gradually increasing the straight-line distance d between the outer edge profile of each first sub light-transmitting portion 321 and the outer edge profile of the second light-emitting portion 212 along the direction from the first display area AA1 to the light-transmitting display area AA3, the area of the metal film layer exposed by each first sub light-transmitting portion 321 can be increased while ensuring that each second light-emitting portion 212 uniformly emits light, so as to realize gradual change of the reflectivity in the second display area AA 2.
Next, the adjustment method of the area and/or density of the second light transmission portions 32 will be described by taking an example in which the orthographic projection of the second light transmission portions 32 on the light emitting layer 2 is positioned between two adjacent second light emitting portions 212.
Referring to fig. 10 to 12, in some alternative embodiments, the second light-transmitting portion 32 includes a plurality of second sub light-transmitting portions 322, and an orthogonal projection of the second sub light-transmitting portions 322 on the light-emitting layer 2 is located between two adjacent second light-emitting portions 212; the area and/or density of the second sub light-transmitting portion 322 gradually increases along the direction of the first display area AA1 toward the light-transmitting display area AA 3. It may be embodied that the area of each of the second sub light-transmitting portions 322 gradually increases in a direction from the first display area AA1 to the light-transmitting display area AA3 when the number of the second sub light-transmitting portions 322 per unit area is the same. Alternatively, when the areas of the second sub light-transmitting portions 322 are the same, the number of the second sub light-transmitting portions 322 per unit area gradually increases along the direction from the first display area AA1 to the light-transmitting display area AA 3. Or, along the direction from the first display area AA1 to the transparent display area AA3, the area of the second sub transparent portions 322 gradually increases and the number of the second sub transparent portions 322 in a unit area also gradually increases, so that the reflectivity of each area in the second display area AA2 gradually increases, and a smooth transition from the reflectivity of the first display area AA1 to the reflectivity of the transparent display area AA3 is realized through the second display area AA 2.
Alternatively, the at least two second sub light-transmitting portions 322 have different shapes (not shown), which reduces diffraction and interference phenomena occurring when light is transmitted therethrough. In addition, the second sub light-transmitting portions 322 with different shapes are alternately arranged to avoid phase superposition as much as possible, thereby further reducing the influence of diffraction and interference effects on light uniformity and ensuring the display effect of the second display area AA 2.
It is understood that, in order to ensure that the light transmittance of the light-transmissive display area AA3 is greater than that of the first display area AA1, the area S1 of the first light-emitting portion 211 is greater than the area S3 of the third light-emitting portion 213 on the basis that the density of the first light-emitting portion 211 is the same as that of the third light-emitting portion 213, thereby increasing the light-transmissive area of the light-transmissive display area AA 3. Referring to fig. 9 to 14, to realize the transition from the area S1 of the first light emitting portion 211 to the area S3 of the third light emitting portion 213, in some alternative embodiments, the area S1 of the first light emitting portion 211 is larger than the area S3 of the third light emitting portion 213, and the area S2 of the second light emitting portion 212 is located in the closed interval formed by the area S1 of the first light emitting portion 211 and the area S3 of the third light emitting portion 213. By adjusting the area S2 of the second light emitting portion 212 to be located between the area S1 of the first light emitting portion 211 and the area S3 of the third light emitting portion 213, the area of each light emitting unit 21 can be ensured to be changed in a gradient manner, thereby ensuring the display uniformity of the display panel.
The reflectance of the second display area AA2 is related to the area and density of the first light transmitting portions 31 in the second display area AA2, in addition to the area and density of the second light transmitting portions 32 in the second display area AA2, and the area and density of the first light transmitting portions 31 are determined by the area and density of the second light emitting portions 212. Therefore, when the densities of the first, second, and third light emitting portions 211, 212, and 213 are the same, the transition of the reflectance of the second display area AA2 from the first display area AA1 to the light-transmissive display area AA3 may also be achieved by adjusting the area of the second light emitting portion 212.
Referring to fig. 9 and 12, in some alternative embodiments, the area S2 of the second light emitting portion 212 is a constant value, and the area S2 of the second light emitting portion 212 satisfies the relation S2 ═ (S1+ S3)/2; in addition, in a direction from the first display area AA1 to the light-transmissive display area AA3, a sum of an area of the first light-transmissive portion 31 and an area of the second light-transmissive portion 32 per unit area of the second display area AA2 gradually increases. That is, when the area S2 of each of the second light emitting parts 212 in the second display area AA2 is the same, the area S2 of the second light emitting part 212 may be equal to the average of the area S1 of the first light emitting part 211 and the area S3 of the third light emitting part 213, so that the areas of the light emitting cells 21 of the first display area AA1, the second display area AA2, and the light-transmissive display area AA3 are varied in an equal gradient, thereby making the transitional display of the display panel more natural. Meanwhile, when the area S2 of the second light emitting part 212 is a fixed value, that is, the area of the first light transmission part 31 per unit area is a fixed value, the area of the second light transmission part 32 per unit area is gradually increased, so that the second display area AA2 realizes smooth transition from the reflectance of the first display area AA1 to the reflectance of the light transmission display area AA3, thereby further ensuring the transitional display effect of the display panel.
Referring to fig. 13 and 14, in other alternative embodiments, the area S2 of the second light emitting portions 212 in the same row is a constant value, and the area S2 of the second light emitting portions 212 in each row decreases in a gradient manner along the direction from the first display area AA1 to the transparent display area AA 3; here, the sum of the area of the first transparent portion 31 and the area of the second transparent portion 32 per unit area of the second display area AA2 is a constant value. By reducing the area S2 of the second light emitting part 212 in a gradient manner, that is, by the second light emitting part 212, transition from the area S1 of the first light emitting part 211 to the area S3 of the third light emitting part 213 is realized, so that transition display of the display panel is more natural. Meanwhile, when the area S2 of the second light emitting part 212 gradually decreases, that is, the area of the first light transmission part 31 in a unit area gradually decreases, the area of the second light transmission part 32 can be gradually increased by setting the sum of the area of the first light transmission part 31 and the area of the second light transmission part 32 in a unit area to a certain value, so that the second display area AA2 realizes a smooth transition from the reflectance of the first display area AA1 to the reflectance of the light transmission display area AA3, thereby further ensuring the transitional display effect of the display panel.
In some alternative embodiments, the area S2 of the second light emitting part 212 in a column of the second display area AA2 close to the first display area AA1 is equal to the area S1 of the first light emitting part 211; and/or, the area S2 of the second light emitting part 212 in a column of the second display area AA2 close to the light transmissive display area AA3 is equal to the area S3 of the third light emitting part 213. That is, in the direction from the first display area AA1 to the light-transmitting display area AA3, the reflectance of the second display area AA2 gradually transitions from the reflectance of the first display area AA1 to the reflectance of the light-transmitting display area AA3, and the area S2 of the second light-emitting portion 212 gradually transitions from the area S1 of the first light-emitting portion 211 to the area S3 of the third light-emitting portion 213, so that the smooth transition from the first display area AA1 to the light-transmitting display area AA3 is realized, and the display uniformity of the display panel is further improved.
