Please refer to fig. 1-5. The present embodiment provides a display panel including: the fingerprint identification module, the array substrate 10 and the light shielding layer 20; the light shielding layer 20 is arranged between the fingerprint identification module and the array substrate 10; the light shielding layer 20 is provided with a light hole 30 corresponding to the fingerprint identification module; the light shielding layer 20 includes at least two light shielding plates stacked one on another, each light shielding plate is provided with an opening, and orthographic projections of the openings on the array substrate 10 are partially overlapped to form a light transmitting hole 30.
The display panel provided by the embodiment further comprises a plurality of light emitting units arranged on one side of the array substrate 10, which is far away from the fingerprint identification module, a pixel limiting layer used for separating the light emitting units, and a first electrode arranged on one side of the pixel limiting layer, which is far away from the array substrate 10; wherein the light emitting unit may be an organic light emitting unit; a second electrode is arranged on one side of the array substrate 10, which is far away from the shading layer 20, the second electrode corresponds to the light-emitting unit, and a thin film transistor electrically connected with the second electrode is arranged in the array substrate 10; when the display panel is used, the thin film transistor controls the second electrode connected with the thin film transistor to be electrified, so that the light-emitting unit emits light, and display of the display panel is realized.
In this embodiment, the light shielding layer 20 is disposed between the array substrate 10 and the fingerprint identification module, and the light shielding layer 20 is provided with a light hole 30 penetrating through the light shielding layer 20, and the light hole 30 is disposed opposite to the fingerprint identification module; when fingerprint identification is carried out, a finger of a user is close to the display panel, light emitted by the light-emitting unit is irradiated on the finger of the user, reflected light is formed on the finger of the user, and the reflected light carries fingerprint information of the finger of the user; the reflected light is emitted to the display panel, passes through the first electrode, the pixel limiting layer and the array substrate 10 and then is emitted to the fingerprint identification module along the light hole 30, and the fingerprint identification module receives the reflected light to realize fingerprint identification.
It should be noted that, in order to avoid the light emitting units blocking the reflected light carrying the fingerprint information from passing through the pixel defining layer, the orthographic projection of the light transmission holes 30 on the array substrate 10 may not coincide with the orthographic projection of the light emitting units on the array substrate 10.
In this embodiment, the light shielding layer 20 includes at least two light shielding plates stacked together, each light shielding plate is provided with an opening, and orthographic projections of the openings on the array substrate 10 are only partially overlapped to form the light transmitting hole 30. Specifically, the number of light shielding plates constituting the light shielding layer 20 is not limited in the present embodiment, and for example: the number of the light shielding plates can be two, three, four and the like; in order to separate two adjacent light shielding plates, a transparent layer can be arranged between the two adjacent light shielding plates, the transparent layer can be an optical glue layer or a polyimide layer, and the transparent layer can also be other transparent film layers.
In this embodiment, the light shielding layer 20 includes at least two light shielding plates, each of which has an opening, and the orthographic projections of the openings on the array substrate 10 are partially overlapped to form the light hole 30; because the orthographic projections of the openings on the array substrate 10 are partially overlapped, the area of each opening is larger than that of the light-transmitting hole 30; compared with the shading layer 20 which only has one shading plate, the area of the hole on the shading plate is increased, so that the area of the shading plate is reduced; when the display panel is pressed, stress can be absorbed through the deformation of the opening after the shading plate is stressed, and then the phenomenon that the display panel is deformed due to the fact that the stress is difficult to release is avoided. In addition, when the display panel is manufactured, other film layers are required to be formed on the light shielding layer 20 in a steaming and plating mode after the light shielding layer 20 is formed, the light shielding plate is heated and expands during steaming and plating, and deformation caused by heating can be released through deformation of the opening due to the fact that the opening in the light shielding plate is large, so that the light shielding plate is prevented from being deformed after being heated, and the thickness of the steaming and plating is prevented from being uneven.
In this embodiment, the material of the light shielding plate is not limited, for example: the shading plate can be a non-transparent plate such as a copper plate, an aluminum plate and the like. Preferably, the area of the opening of each light shielding plate can be increased as much as possible to further reduce the area of each light shielding plate on the premise of ensuring that light can only pass through the light shielding layer 20 through the light holes 30 of the light shielding layer 20.
In one implementable manner, the light shielding layer 20 includes two light shielding plates disposed in a stack; specifically, the light shielding plates include a first light shielding plate 201 and a second light shielding plate 202, a first opening 2011 is disposed on the first light shielding plate 201, a second opening 2021 is disposed on the second light shielding plate 202, and the first opening 2011 overlaps with an orthographic projection portion of at least one second opening 2021 on the array substrate 10. The first opening 2011 and the second opening 2021 corresponding to the overlapped orthographic projections form a light transmission hole 30, so that the area of the light transmission hole 30 is smaller than the areas of the first opening 2011 and the second opening 2021, and the first opening 2011 and the second opening 2021 can be made larger; the areas of the first light shielding plate 201 and the second light shielding plate 202 are reduced compared to when the light shielding layer 20 has only one light shielding plate.
Specifically, the shape of the first opening 2011 in the present embodiment may be various, for example: the first opening 2011 may have a regular shape such as a rectangle, a triangle, or other irregular shape. Similarly, the shape of the second opening 2021 may be varied, as long as the orthographic projections of the first opening 2011 and the second opening 2021 on the array substrate 10 are partially overlapped to form the light-transmitting hole 30; for example: the second opening 2021 may have a regular shape such as a rectangle, a triangle, or other irregular shape of the second opening 2021. It should be noted that the shape of the first opening 2011 and the shape of the second opening 2021 may be the same, or the shape of the first opening 2011 and the shape of the second opening 2021 may be different.
With continued reference to fig. 2, a first opening 2011 of the first shutter plate 201 and a second opening 2021 of the second shutter plate 202 illustratively form a light-transmitting aperture 30.
With continued reference to fig. 3, the first opening 2011 of the first light shielding plate 201 and the second openings 2021 of the second light shielding plate 202 illustratively form a plurality of light-transmitting holes 30. For convenience of description, the first opening 2011 and the second opening 2021 are rectangular, and at this time, four corners of the first opening 2011 correspond to one second opening 2021 respectively, and form four light-transmitting holes 30. Of course, one first opening 2011 may also correspond to two second openings 2021 to form two light-transmitting holes 30; or the first opening 2011 corresponds to the three second openings 2021 to form three light-transmitting holes 30.
Continuing to refer to fig. 3, when fingerprint identification is performed, a user finger is close to the display panel, light emitted by the light-emitting unit is irradiated on the user finger, and reflected light is formed on the user finger, and the reflected light carries fingerprint information of the user finger; the reflected light beam is emitted to the display panel, and passes through the first electrode, the pixel defining layer and the array substrate 10 to enter the first opening 2011 of the first light shielding plate 201, and then passes through the second light shielding plate 202 through the overlapping position of the second opening 2021 and the first opening 2011, that is, the reflected light beam passes through the light transmitting hole 30 and is emitted to the fingerprint identification module, and the fingerprint identification module receives the reflected light beam to realize fingerprint identification.
With continued reference to fig. 4, in other implementations, there may be three light-shielding plates that constitute the light-shielding layer 20; specifically, the light shielding plates include a first light shielding plate 201, a second light shielding plate 202 and a third light shielding plate 203, a first opening 2011 is arranged on the first light shielding plate 201, a second opening 2021 is arranged on the second light shielding plate 202, and a third opening 2031 is arranged on the third light shielding plate 203; an orthogonal projection of the first opening 2011 on the array substrate 10 at least partially overlaps an orthogonal projection of the second opening 2021 on the array substrate 10, and the overlapping orthogonal projection partially overlaps an orthogonal projection of the third opening 2031 on the array substrate 10. The area of each light shielding plate can be further reduced as compared with having two light shielding plates.
Taking the orientation shown in fig. 4 as an example, the light shielding layer 20 is disposed at the lower portion of the array substrate 10, and the first light shielding plate 201, the second light shielding plate 202, and the third light shielding plate 203 are sequentially disposed from top to bottom, the first opening 2011 on the first light shielding plate 201 at least partially overlaps the second opening 2021 on the second light shielding plate 202, and the overlapping region partially overlaps the third light shielding plate 203 to form the light hole 30. Of course, the arrangement order of the first light shielding plate 201, the second light shielding plate 202 and the third light shielding plate 203 in this embodiment may be various, for example: the first light shielding plate 201, the third light shielding plate 203 and the second light shielding plate 202 are sequentially arranged from the array substrate 10 to the fingerprint identification module, or the second light shielding plate 202, the third light shielding plate 203 and the first light shielding plate 201 are sequentially arranged from the array substrate 10 to the fingerprint identification module.
Continuing to refer to fig. 4, when fingerprint identification is performed, a user finger is close to the display panel, light emitted by the light-emitting unit is irradiated on the user finger, and reflected light is formed on the user finger, and the reflected light carries fingerprint information of the user finger; the reflected light beam is emitted to the display panel, and passes through the first electrode, the pixel defining layer and the array substrate 10 to enter the first opening 2011 of the first light shielding plate 201, then passes through the second light shielding plate 202 at the overlapping position of the second opening 2021 and the first opening 2011, and then passes through the third light shielding plate 203 at the overlapping position of the third opening 2031 and the second opening 2021, that is, the reflected light beam passes through the light transmitting hole 30 and is emitted to the fingerprint identification module, and the fingerprint identification module receives the reflected light beam to realize fingerprint identification.
In the display panel provided by this embodiment, the light shielding layer 20 is disposed between the fingerprint identification module and the array substrate 10, and the light shielding layer 20 is provided with the light holes 30 corresponding to the fingerprint identification module; the light-transmitting hole 30 is formed by making the light-shielding layer 20 include at least two light-shielding plates which are arranged in a stacked manner, and each light-shielding plate is provided with an opening, and orthographic projections of the openings on the array substrate 10 are partially overlapped; because the orthographic projections of the openings on the array substrate 10 are partially overlapped, the area of each opening is larger than that of the light hole 30, compared with the case that the light shielding layer 20 is only provided with one light shielding plate, the area of the hole on the single light shielding plate is increased, and the area of the light shielding plate is reduced; when display panel received to press, can pass through open-ended deformation absorption stress behind the light screen atress, and then avoid stress to be difficult to release and lead to display panel to warp, improved display panel's product quality.
With continued reference to fig. 1-4, in the display panel provided in this embodiment, the light-transmitting holes 30 are multiple, and the multiple light-transmitting holes 30 are arranged at intervals. The reflection ray that carries fingerprint information can be through a plurality of light trap 30 simultaneous directive fingerprint identification module, and then has improved the fingerprint identification effect.
Specifically, the plurality of light-transmitting holes 30 may be arranged regularly, for example: the plurality of light holes 30 are arranged in an array; of course, the plurality of light holes 30 may be arranged randomly.
In this embodiment, the display panel has an identification area for fingerprint identification, and each light-transmitting hole 30 is provided in the fingerprint identification area of the display panel.
Specifically, the area of the fingerprint identification area may be smaller than the area of the display panel, that is, fingerprint identification is performed on a partial area of the display panel; or the area of the fingerprint identification area is equal to the area of the display panel, namely the fingerprint identification area is superposed with the display area of the display panel, and fingerprint identification can be carried out on the whole display panel.
With continued reference to fig. 5, the display panel in the present embodiment further includes a transparent conductive layer 40, and the transparent conductive layer 40 is disposed between the active layer 101 of the array substrate 10 and the light shielding layer 20. The opening on the light shielding plate may cause the conductive layer on the lower portion of the array substrate 10 to be uneven, and the current and voltage of the array substrate 10 are uneven, so that the brightness of the display panel is uneven. The transparent conductive layer 40 can form a uniform conductive layer between the array substrate 10 and the light shielding layer 20, so that the uniformity of current and voltage of the array substrate 10 is improved, the brightness of the display panel is uniform, and the display effect is improved.
In this embodiment, the material of the transparent conductive layer 40 is not limited, for example: the transparent conductive layer 40 can be an indium tin oxide layer, and the transparent conductive layer 40 made of indium tin oxide has good transparency so as to avoid affecting light transmission; of course, the transparent conductive layer 40 may be made of other transparent and conductive materials.
The transparent conductive layer 40 is located between the active layer 101 of the array substrate 10 and the light shielding layer 20 in this embodiment, and in an implementation manner, the transparent conductive layer 40 may be located between the array substrate 10 and the light shielding layer 20. Specifically, the array substrate 10 includes a substrate 102 on a side of the active layer 101 facing the fingerprint recognition module, and the transparent conductive layer 40 is disposed between the substrate 102 and the light shielding layer 20. That is, the transparent conductive layer 40 is located outside the array substrate 10, and in this case, the array substrate 10, the transparent conductive layer 40, and the light-shielding layer 20 may be separately manufactured and then bonded to each other, thereby facilitating the manufacture of the display panel.
In other embodiments, the transparent conductive layer 40 may be disposed inside the array substrate 10. Specifically, the array substrate 10 includes an underlying substrate 102 disposed toward the light-shielding layer 20, and the transparent conductive layer 40 may be disposed inside the underlying substrate 102; or the transparent conductive layer 40 is disposed between the base substrate 102 and the active layer 101. When the transparent conductive layer 40 is located between the base substrate 102 and the active layer 101, the transparent conductive layer 40 may be disposed adjacent to the active layer, with the transparent insulating layer 103 disposed between the transparent conductive layer 40 and the active layer 101. The transparent insulating layer 103 may realize an insulating connection between the transparent conductive layer 40 and the active layer 101 so as not to influence the operation of the active layer 101 by the transparent conductive layer 40. Of course, other film layers of the array substrate 10 may also be disposed between the transparent conductive layer 40 and the active layer 101, which is not limited in this embodiment.
