[0046] Example embodiments now will be described more fully hereinafter with reference to the accompanying drawings. Example embodiments, may, however, be implemented in many different forms and should not be construed as limited to the implementations set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. Like reference numerals refer to like elements throughout the specification. Moreover, the figures shown are only schematic and the concepts presented herein can be implemented in a variety of forms. In addition, each of the figures can not be drawn to scale and should not be regarded as limiting the presently disclosed concepts.

[0047] Although relative terms such as "on", "under", "lower", "upper" and the like can be used herein to describe one component's or feature's relationship to another component or feature as illustrated in the figures, these terms are used herein only to facilitate the description of the examples disclosed herein and do not limit the scope of the claims. Terms concerning orientations such as "on", "under", "lower", "upper" and the like are used as examples only, and are utilized for convenience and illustrative purposes and are not intended to limit the scope of the application or to imply that a described feature must necessarily be oriented in a particular way. Terms concerning spatial relationships, such as "on", "under", "lower", "upper" and the like are used herein for purposes of clarity only and can encompass different positions of one component with respect to another component, including absolute positions as well as relative movement between components. For example, a component can be said to be "on" or "under" another component even though it is actually reversed and placed "under" or "on" the other component. A component can also be said to be "on" or "under" another component even though it is actually connected to the other component through an intermediate structure. It will be understood that when a structure is "on" another structure, it can mean that the structure is formed integrally with the other structure or that the structure is disposed "directly" on the other structure or that the structure is disposed "indirectly" on the other structure through another structure.

[0048] The terms "one", "a", "an", "the" and "at least one" are used to indicate that "one or more" of something is present with the understanding that the something present can be one or multiple number of things. The term "includes" and the like means "including, but not limited to". The term "first", "second", and "third" and the like are used to indicate different layers or regions, and are not intended to signify relative importance or significance.

[0049] In the present application, unless specifically stated and limited otherwise, the term "connected" is used broadly and encompasses direct and indirect connections, fixed or detachable connections, and one-body. The term "and / or" is merely used to describe an associated relationship of associated objects, and means that three relationships can exist, for example, A and / or B can mean that A exists alone, A and B exist together, or B exists alone. In addition, the character " / " in this document generally represents an "or" relationship between the associated objects.

[0050] The example embodiments of the present disclosure provide a display device, with reference to Figures 2-5As shown, the display device can include a display panel 1, a light shielding member 2, and a light sensing element 3; the display panel 1 has a display surface and a side surface, the side surface is connected to the display surface and is arranged perpendicularly to the display surface; the light shielding member 2 is arranged at least on the side surface of the display panel 1; and the light sensing element 3 is arranged on a side of the light shielding member 2 away from the display panel 1.

[0051] The display device of the present disclosure is provided with the light shielding member 2 between the light sensing element 3 and the display panel 1, and the light shielding member 2 can shield the light emitted from the side surface of the display panel 1, so as to avoid the light emitted from the side surface of the display panel 1 from reaching the light sensing element 3, thereby avoiding the light emitted from the side surface of the display panel 1 from interfering with the light sensing element 3, improving the accuracy of the light sensing element 3 in sensing the external ambient light, and thus accurately controlling the display brightness of the display device according to the sensing value of the light sensing element 3, and further making the display device meet the requirements of the user.

[0052] In the present example embodiment, the display panel 1 can include a substrate, and the material of the substrate can include inorganic materials, for example, the inorganic materials can be glass, quartz, metal, etc. The material of the substrate can also include organic materials, for example, the organic materials can be polyimide, polycarbonate, polyacrylate, polyetherimide, polyethersulfone, polyethylene terephthalate, polyethylene naphthalate, etc. The substrate can be formed by multiple layers of materials, for example, the substrate can include multiple base layers, and the material of the base layers can be any of the above materials. Of course, the substrate can also be provided as a single layer, and can be any of the above materials.

[0053] An isolation layer can also be arranged on one side of the substrate, which can block water vapor and impurity ions in the substrate (especially organic materials), and can also add hydrogen ions to the active layer formed subsequently, and the material of the isolation layer is an insulating material.

[0054] The active layer is arranged on a side of the isolation layer away from the substrate, and the active layer can include a channel portion and conductor portions arranged at both ends of the channel portion. A gate insulating layer is arranged on a side of the active layer away from the substrate, a gate electrode is arranged on a side of the gate insulating layer, an interlayer dielectric layer is arranged on a side of the gate electrode away from the substrate, and a through hole is arranged on the interlayer dielectric layer and connected to the conductor portions. A first source / drain layer is arranged on a side of the interlayer dielectric layer away from the substrate, and the first source / drain layer can include a source electrode and a drain electrode, which are respectively connected to the two conductor portions through two through holes. A passivation layer is arranged on a side of the source electrode and the drain electrode away from the substrate, and a through hole is arranged on the passivation layer and connected to the source electrode. The active layer, the gate electrode, the source electrode, and the drain electrode form a thin film transistor.

[0055] Note that the thin film transistor described in this specification is a top-gate thin film transistor, and in other example embodiments of the present disclosure, the thin film transistor can also be a bottom-gate or dual-gate type, and the specific structure thereof will not be described here. Also, in the case of using a thin film transistor of opposite polarity or in the case of a change in the current direction in the operation of the circuit, the functions of the "source" and the "drain" are sometimes exchanged with each other. Therefore, in this specification, the "source" and the "drain" can be exchanged with each other.

[0056] The light-emitting substrate is provided on the side of the passivation layer away from the substrate substrate, and can include a first electrode, a pixel definition layer, a light-emitting layer group, and a second electrode.

[0057] Specifically, the first electrode is provided on the side of the passivation layer away from the substrate substrate, and is connected to the source of the driving backplane through the via hole. The first electrode can be an anode (pixel electrode).

[0058] The pixel definition layer is provided on the side of the first electrode away from the substrate substrate, and has an opening portion exposing at least part of the first electrode. The light-emitting layer group is provided at least in the opening portion and is in contact with the first electrode. The second electrode is provided on the side of the light-emitting layer group away from the substrate substrate, and can be a cathode (common electrode). The second electrode is connected to the ground VSS. The light-emitting layer group in one opening portion emits light to form one sub-pixel, and the light-emitting substrate can include a plurality of sub-pixels.

[0059] The light-emitting layer group can include a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, and an electron injection layer stacked in sequence. The hole injection layer is in contact with the first electrode, and the electron injection layer is in contact with the second electrode. Of course, in other example embodiments of the present disclosure, the light-emitting layer group can only include a hole transport layer, a light-emitting layer, and an electron transport layer. The light-emitting layer group can also have other structures, and the specific structure thereof can be set as needed.

[0060] The encapsulation layer group is provided on the side of the second electrode away from the substrate substrate. The encapsulation layer group can be provided as multiple layers, and can include an organic layer and an inorganic layer. Specifically, the encapsulation layer group can include a first inorganic layer, an organic layer provided on the side of the first inorganic layer away from the substrate substrate, and a second inorganic layer provided on the side of the organic layer away from the substrate substrate. The materials of the first inorganic layer, the organic layer, and the second inorganic layer will not be described here. Of course, the encapsulation layer group can also include more layers or fewer layers.

[0061] The first electrode may include a reflective layer to reflect the light emitted from the light-emitting layer group, allowing the light to exit from the encapsulation layer group. Therefore, the side of the display panel facing away from the substrate is the display surface; specifically, the side of the encapsulation layer group of the display panel facing away from the substrate is the display surface. Furthermore, the outer peripheral surface of the display panel is connected to and intersects with the display surface, and the outer peripheral surface of the display panel is the side surface of the display panel. Of course, in some other exemplary embodiments of this disclosure, the second electrode may be configured as a reflective layer, allowing the light emitted from the light-emitting layer group to exit from the substrate, with the side of the substrate facing away from the encapsulation layer group being the display surface.

[0062] Additionally, refer to Figure 1 As shown, the inventors discovered that the main reason why the photosensitive element is inaccurate in sensing external ambient light is that the light emitted by the light-emitting layer group has a large angle of view, which can be close to 180 degrees. That is, the light emitted by the light-emitting layer group not only shines out from one side of the encapsulation layer group, but also some of the light shines out from the side of the display panel. This light shines on the photosensitive element, causing interference to the photosensitive element and affecting the photosensitive element's ability to sense external ambient light.

[0063] In some other exemplary embodiments of this disclosure, a touch layer group may also be provided on the side of the encapsulation layer group facing away from the substrate, through which the touch function of the display device can be realized.

[0064] In this example embodiment, a polarizer 7 is provided on the display surface of the display panel 1. The polarizer 7 can reduce the reflection of ambient light by the display panel 1, so that the display device can be clearly displayed even under bright ambient light.

[0065] In this example embodiment, an adhesive layer 6 is provided on the side of the polarizer 7 facing away from the display panel 1. The adhesive layer 6 is made of OCA (Optically Clear Adhesive) optical adhesive. OCA optical adhesive is a special adhesive used to bond transparent optical components (such as lenses). It has the characteristics of being colorless and transparent, having a light transmittance of more than 95%, good bonding strength, being able to cure at room temperature or medium temperature, and having low curing shrinkage.

[0066] A transparent cover plate 5 is provided on the side of the adhesive layer 6 facing away from the display panel 1, that is, the transparent cover plate 5 is bonded to the polarizer 7 through the adhesive layer 6. The transparent cover plate 5 can protect the display device.

[0067] In the example embodiment, the display panel 1, the polarizer 7 and the adhesive layer 6 are flush on the four sides, and the orthographic projection of the display panel 1 on the transparent cover plate 5 is within the transparent cover plate 5, and there is a set distance between the edge line of the orthographic projection of the display panel 1 on the transparent cover plate 5 and the edge line of the transparent cover plate 5, that is, the area of the display panel 1 is smaller than the area of the transparent cover plate 5, so that the transparent cover plate 5 protrudes from the display panel 1. Of course, in other example embodiments of the present disclosure, the edge line of the orthographic projection of the display panel 1 on the transparent cover plate 5 can coincide with the edge line of the transparent cover plate 5.

[0068] In the example embodiment, a heat dissipation film 4 is arranged on the side of the display panel 1 away from the display, and the heat dissipation film 4 can include a buffer layer 41 and a conductor layer 42. The material of the conductor layer 42 can be various metals (copper, aluminum, steel, etc.), graphite and other materials with certain electrical conductivity. The material of the buffer layer 41 can be foam, rubber and other materials with certain elasticity. Since various metals, graphite and other materials are hard materials, the buffer layer 41 is arranged between the conductor layer 42 and the display panel 1 to avoid damage to the display panel 1.

[0069] An adhesive 43 is further arranged between the buffer layer 41 and the display panel 1 to bond the heat dissipation film 4 to the display panel 1. A PI (polyimide) layer is further arranged between the buffer layer 41 and the conductor layer 42 to improve the impact resistance of the heat dissipation film 4, protect the back of the display panel 1, prevent back impact, and improve film printing display defects.

[0070] Referring to Figure 3 As shown in the cross-sectional view of the light shielding piece 2, the light shielding piece 2 can include a light shielding layer 22, and the material of the light shielding layer 22 can be PC (polycarbonate) material, which can be formed into an integrated structure through injection molding process. A glue layer is arranged on the side of the light shielding layer 22 close to the display panel 1, and the light shielding piece 2 can be bonded to the display panel 1, the transparent cover plate 5 and the heat dissipation film 4 through the glue layer. Moreover, the light shielding piece 2 is designed to be profiled to ensure that the light shielding piece 2 can be completely attached to the side of the display panel. The PC material itself has light blocking property and shape stability, which avoids secondary light leakage defects of the display device during transportation and overall assembly.

[0071] Referring to Figure 4As shown, in another example embodiment of the present disclosure, the light shielding piece 2 can include a conductive layer 21 and a light shielding layer 22; the conductive layer 21 is arranged at least on the side of the display panel 1, specifically, one end of the conductive layer 21 is arranged on the side of the heat dissipation film 4 away from the display panel 1, and the other end of the conductive layer 21 is arranged on the side of the transparent cover plate 5 close to the display panel 1, that is, the conductive layer 21 is arranged not only on the side of the display panel 1, but also connects the heat dissipation film 4 and the transparent cover plate 5; the heat dissipation film 4 is grounded, and the surface of the transparent cover plate 5 can be grounded through the conductive layer 21 due to the charge accumulation caused by the copper bar test, and the static electricity generated by the friction of the transparent cover plate 5 can also be grounded through the conductive layer 21; thereby avoiding the accumulation of static electricity on the surface of the transparent cover plate 5, avoiding the influence of static electricity on the array substrate of the display panel 1, and avoiding the influence on the display of the display panel 1. Moreover, the anti-static capability of the display device is increased.

[0072] The material of the conductive layer 21 can be conductive cloth, which is a fiber cloth (generally commonly used polyester fiber cloth) as a base material, and after pre-treatment, a metal plating layer is applied to make it have metal characteristics and become a conductive fiber cloth. It can be divided into: nickel-plated conductive cloth, gold-plated conductive cloth, carbon-plated conductive cloth, and aluminum foil fiber composite cloth. There are plain and grid distinctions in appearance. Of course, the conductive layer 21 can also be a metal layer directly plated on one side of the light shielding layer 22.

[0073] The light shielding layer 22 is arranged on the side of the conductive layer 21 away from the display panel 1, and the material of the light shielding layer 22 can be black Mylar, and can also be other black resins, rubbers and other flexible materials. Through the light shielding layer 22, the light emitted from the side of the display panel 1 can be shielded, avoiding the light emitted from the side of the display panel 1 from reaching the photosensitive element 3, thereby avoiding the interference of the light emitted from the side of the display panel 1 on the photosensitive element 3, improving the accuracy of the photosensitive element 3 in sensing the external environment light, and further making the display device meet the requirements of the user.

[0074] Further, referring to Figure 5 As shown, in still another example embodiment of the present disclosure, a protective layer 23 is further arranged between the conductive layer 21 and the light shielding piece 2, and the material of the protective layer 23 can be foam, which has a certain elasticity. When the side of the display device is impacted, the protective layer 23 can absorb most of the impact force, avoiding the transmission of the impact force to the side of the display panel 1, thereby achieving the protection of the display panel 1.

[0075] A glue layer is arranged on the side of the conductive layer 21 close to the display panel 1, and the light shielding piece 2 can be bonded to the display panel 1, the transparent cover plate 5 and the heat dissipation film 4 through the glue layer. Moreover, Figure 4 and Figure 5The material of each layer of the light shielding member 2 in the example embodiment is a flexible material, which can deform with the display panel 1, the transparent cover plate 5, and the heat dissipation film 4, so that the light shielding member 2 can be closely attached to the display panel 1, the transparent cover plate 5, and the heat dissipation film 4, avoiding secondary light leakage in the transportation and assembly of the display device.

[0076] In addition, in the example embodiment, the conductive layer 21, the protective layer 23, and the light shielding layer 22 can be provided in the same shape. Specifically, as follows:

[0077] Referring to Figures 3-5 The heat dissipation film 4, the display panel 1, and the transparent cover plate 5 are sequentially protruded to form a stepped shape. In this case, the light shielding member 2 can include a first portion 24, a second portion 25, a third portion 26, a fourth portion 27, and a fifth portion 28.

[0078] The first portion 24 is provided on the side of the transparent cover plate 5 close to the display panel 1, specifically, the first portion 24 is provided on the side of the end of the transparent cover plate 5 protruding from the display panel 1 close to the display panel 1, and the first portion 24 is arranged parallel to the display surface of the display panel 1.

[0079] The second portion 25 is connected to the first portion 24, and the second portion 25 is arranged perpendicular to the display surface of the display panel 1, and the second portion 25 is provided on the side surface of the display panel 1.

[0080] The third portion 26 is connected to the side of the second portion 25 away from the first portion 24, and the third portion 26 is arranged parallel to the display surface of the display panel 1, and the third portion 26 is provided on the side of the display panel 1 away from the transparent cover plate 5, specifically, the third portion 26 is provided on the side of the end of the display panel 1 protruding from the heat dissipation film 4 away from the transparent cover plate 5.

[0081] The fourth portion 27 is connected to the side of the third portion 26 away from the second portion 25, and the fourth portion 27 is arranged perpendicular to the display surface of the display panel 1, and the fourth portion 27 is provided on the side surface of the heat dissipation film 4, and the side surface of the heat dissipation film 4 is arranged parallel to the side surface of the display panel 1.

[0082] The fifth portion 28 is connected to the side of the fourth portion 27 away from the third portion 26, and the fifth portion 28 is arranged parallel to the display surface of the display panel 1, and the fifth portion 28 is provided on the side of the heat dissipation film 4 away from the display panel 1.

[0083] Of course, in some other example embodiments of the present disclosure, for example, in the case where the side of the heat dissipation film 4 is flush with the side of the display panel 1, the light shielding piece 2 can only include the first portion 24, the second portion 25, the fourth portion 27, and the fifth portion 28; the second portion 25 and the fourth portion 27 are connected and coplanarly arranged, that is, the second portion 25 and the fourth portion 27 are arranged as one part.

[0084] Further, referring to FIG. 1, the light shielding piece 2 is arranged on the display panel 1, and the light shielding piece 2 includes a first portion 24, a second portion 25, a third portion 26, a fourth portion 27, and a fifth portion 28. The first portion 24 is arranged on the display panel 1, and the second portion 25 is arranged on the third portion 26. The fourth portion 27 is arranged on the third portion 26, and the fifth portion 28 is arranged on the fourth portion 27. The second portion 25 and the fourth portion 27 are connected and coplanarly arranged, that is, the second portion 25 and the fourth portion 27 are arranged as one part. Figure 2 Further, referring to FIG. 1, the light shielding piece 2 is arranged on the display panel 1, and the light shielding piece 2 includes a first portion 24, a second portion 25, a third portion 26, a fourth portion 27, and a fifth portion 28. The first portion 24 is arranged on the display panel 1, and the second portion 25 is arranged on the third portion 26. The fourth portion 27 is arranged on the third portion 26, and the fifth portion 28 is arranged on the fourth portion 27. The second portion 25 and the fourth portion 27 are connected and coplanarly arranged, that is, the second portion 25 and the fourth portion 27 are arranged as one part.

[0085] Specifically, in the case where the photosensitive element 3 is directly arranged on the transparent cover plate 5 close to the display panel 1, the photosensitive surface of the photosensitive element 3 faces the transparent cover plate 5, and the photosensitive surface of the photosensitive element 3 is arranged opposite to the avoiding portion 241, the orthographic projection of the photosensitive surface of the photosensitive element 3 on the transparent cover plate 5 is located within the orthographic projection of the avoiding portion 241 on the transparent cover plate 5, for example, the edge line of the orthographic projection of the photosensitive surface of the photosensitive element 3 on the transparent cover plate 5 coincides with the edge line of the orthographic projection of the avoiding portion 241 on the transparent cover plate 5, or the orthographic projection of the avoiding portion 241 on the transparent cover plate 5 covers and is larger than the orthographic projection of the photosensitive surface of the photosensitive element 3 on the transparent cover plate 5. Avoiding the light shielding piece 2 from shielding the photosensitive surface of the photosensitive element 3, avoiding reducing the amount of ambient light reaching the photosensitive element 3, and avoiding affecting the accuracy of the photosensitive element 3 in sensing the external ambient light. The external ambient light can directly pass through the transparent cover plate 5 and the avoiding portion 241 to reach the photosensitive surface of the photosensitive element 3, so that the photosensitive element 3 can detect the external ambient light.

[0086] In addition, in some example embodiments of the present disclosure, the display device can further include a shielding layer 8 for shielding the non-display area around the display panel 1, and a portion of the shielding layer 8 is located between the transparent cover plate 5 and the photosensitive element 3. A via hole 9 is provided on the shielding layer 8, that is, the via hole 9 is provided on the portion of the shielding layer 8 located between the transparent cover plate 5 and the photosensitive element 3. The photosensitive surface of the photosensitive element 3 is arranged opposite to the via hole 9, and the orthographic projection of the photosensitive surface of the photosensitive element 3 on the transparent cover plate 5 is located within the orthographic projection of the via hole 9 on the transparent cover plate 5. For example, the edge line of the orthographic projection of the photosensitive surface of the photosensitive element 3 on the transparent cover plate 5 coincides with the edge line of the orthographic projection of the via hole 9 on the transparent cover plate 5, or the orthographic projection of the via hole 9 on the transparent cover plate 5 covers and is larger than the orthographic projection of the photosensitive surface of the photosensitive element 3 on the transparent cover plate 5. The shielding layer 8 avoids shielding the photosensitive surface of the photosensitive element 3, avoids reducing the amount of ambient light reaching the photosensitive element 3, and avoids affecting the accuracy of the photosensitive element 3 in sensing the external ambient light. The external ambient light can directly pass through the transparent cover plate 5 and the via hole 9 to reach the photosensitive surface of the photosensitive element 3, so that the photosensitive element 3 can detect the external ambient light.

[0087] In addition, the orthographic projection of the via hole 9 on the transparent cover plate 5 is located within the orthographic projection of the avoidance portion 241 on the transparent cover plate 5. For example, the edge line of the orthographic projection of the via hole 9 on the transparent cover plate 5 coincides with the edge line of the orthographic projection of the avoidance portion 241 on the transparent cover plate 5, or the orthographic projection of the avoidance portion 241 on the transparent cover plate 5 covers and is larger than the orthographic projection of the via hole 9 on the transparent cover plate 5. The spacing between the edge line of the orthographic projection of the avoidance portion 241 on the transparent cover plate 5 and the edge line of the orthographic projection of the via hole 9 on the transparent cover plate 5 is greater than or equal to 0.3 mm and less than or equal to 0.6 mm, for example, which can be 0.35 mm, 0.4 mm, 0.44 mm, 0.48 mm, 0.5 mm, 0.55 mm, etc.

[0088] Of course, in some other example embodiments of the present disclosure, instead of shielding the non-display area around the display panel 1 by the shielding layer 8, the non-display area around the display panel 1 can be shielded by the housing of the display device. In this case, the via hole 9 can be provided on the housing, that is, the housing can serve as the shielding layer 8, as long as the via hole 9 is arranged opposite to the photosensitive surface of the photosensitive element 3 to avoid shielding the photosensitive surface of the photosensitive element 3.

[0089] Other embodiments of the present disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. It is intended that the specification and examples be considered as exemplary only, with the true scope and spirit of the present disclosure being indicated by the following claims.
