Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of an embodiment of a flexible display device in a flattened state in the prior art, and fig. 2 is a schematic structural diagram of an embodiment of the flexible display device in a bent state in fig. 1. The flattened state may be understood as a state in which the flexible display screen 10 is in a flat state or a state in which the display area is maximized in the flexible display device. The bent state may be understood as a state in which a part of the flexible display screen 10 in the flexible display device is in a bent state or a state in which the display area is small. In the flattened state, the orthographic projection of the photosurface 120 of the optical element 12 on the light-transmitting area 140 is equal to the distance between the left side and the right side of the light-transmitting area 140, and the light-transmitting area 140 can cover the whole photosurface 120. In the bending state, each film layer in the flexible display screen 10 translates, as shown in fig. 2, each film layer in the flexible display screen 10 moves to different degrees, and the more the film layer near the outer surface moves, the position of the corresponding light-transmitting region 140 also moves along with the movement of the film layer. When the movement of each film layer in the flexible display screen 10 is as shown in fig. 2, the relative positions of the photosensitive surface 120 and the light-transmitting area 140 of the optical element 12 are changed; when the optical element 12 is a front-facing camera, this phenomenon may cause a change in the viewing angle range and effect of photographing.
In order to solve the above-mentioned technical problems, please refer to fig. 3, fig. 3 is a schematic structural diagram of an embodiment of the flexible display device of the present application, wherein fig. 3 (a) corresponds to a flattened state, and fig. 3 (b) corresponds to a bent state. The flexible display device comprises a flexible display module 2 and an optical element 4; wherein the flexible display module 2 can be sold separately from the optical element 4, i.e. the flexible display module 2 can exist as a separate protective body. The flexible display device may be a display device in a folded or drawn form, which may be a cell phone, a tablet, or the like. Further, the flexible display module 2 includes a flexible display screen 20; the flexible display 20 may include a light shielding layer 200, and a light transmitting region 2000 is disposed on the light shielding layer 200, and a position of the light transmitting region 2000 corresponds to a position of the optical element 4. In this embodiment, the optical element 4 may be a front camera or a fingerprint recognition element, and the flexible display 20 may include a display surface, and the optical element 4 is disposed on a side of the light shielding layer 200 facing away from the display surface. Wherein the flexible display 20 is switchable between a flattened state and a folded state; and in the flattened state and the folded state, the optical axis L1 of the optical element 4 passes through the center of the light transmitting region 2000. Alternatively, in the present embodiment, the area of the light transmitting region 2000 is greater than or equal to the photosensitive area of the optical element 4 in the flattened state and the folded state, which can be understood as the area of the photosensitive surface of the optical element 4.
In the above design manner, no matter the flexible display screen 20 is in the flattened state or the folded state, since the optical axis L1 of the optical element 4 passes through the center of the light-transmitting area 2000, the relative positions of the light-transmitting area 2000 on the light-shielding layer 200 and the optical element 4 in different states can be considered to be unchanged, and when the optical element 4 is a front camera, the photographing view angle and the photographing effect of the front camera can be unchanged, so as to improve the user experience.
In one embodiment, referring to fig. 3, the light shielding layer 200 provided by the present application includes a first light shielding sub-layer 2002 and a second light shielding sub-layer 2004 stacked together, wherein a first light transmitting hole a is formed on the first light shielding sub-layer 2002, and a second light transmitting hole B is formed on the second light shielding sub-layer 2004; wherein, during switching between the flattened state (as shown in fig. 3 (a)) and the folded state (as shown in fig. 3 (b)), the first shielding sub-layer 2002 is capable of moving in opposite directions relative to the second shielding sub-layer 2004; for example, as shown in fig. 3, when switching from the flattened state to the folded state, the first shielding sub-layer 2002 translates to the left and the second shielding sub-layer 2004 translates to the right; when switching from the folded state to the flattened state, the first shielding sublayer 2002 translates rightward, and the second shielding sublayer 2004 translates leftward. In the flattened state, the orthographic projection of the first light transmitting hole a on the second light shielding sub-layer 2004 and the region where the second light transmitting hole B overlap each other form a first light transmitting region 2000a; in the folded state, the area where the orthographic projection of the first light hole a on the second light shielding sub-layer 2004 and the second light hole B overlap each other forms the second light transmitting area 2000B, and the optical axis L1 of the optical element 4 passes through the center of the first light transmitting area 2000a and the center of the second light transmitting area 2000B. In the above design manner, the first shielding sub-layer 2002 and the second shielding sub-layer 2004 which are stacked are mutually matched to achieve the purpose that the positions of the whole light transmission area 2000 and the optical element 4 in the flattened state and the bent state are kept relatively unchanged, and the structural design is simpler. Alternatively, in the present embodiment, the areas of the first light-transmitting region 2000a and the second light-transmitting region 2000b are greater than or equal to the photosensitive area of the optical element 4.
Optionally, in this embodiment, please continue to refer to fig. 3, the flexible display screen 20 provided by the present application includes:
a substrate 204; in this embodiment, the substrate 204 may have flexibility, and the material thereof may be polyimide or the like.
The flexible cover 202 is located on one side of the substrate 204 and includes a first portion 2020, a connecting portion 2022 and a second portion 2024 connected to each other, where the first portion 2020 and the second portion 2024 are stacked, and the first portion 2020 is far from the substrate 204 relative to the second portion 2024. The first portion 2020 is capable of moving the second portion 2024, and the moving directions of the first portion 2020 and the second portion 2024 are opposite; wherein the first shielding sub-layer 2002 is fixedly disposed on the first portion 2020, and the second shielding sub-layer 2004 is fixedly disposed on the second portion 2024. In this embodiment, the material of the flexible cover plate 202 may be at least one of an optical PET film, a foldable aramid film, and a foldable ultra-thin glass (UTG). The boundary between the first portion 2020, the connecting portion 2022, and the second portion 2024 is not specifically limited in the present application, and the regions of the flexible cover 202 which are kept opposite to each other in the flattened state and the folded state may be referred to as the first portion 2020 and the second portion 2024, respectively; the connecting portion 2022 may be partially located in a gap between the first portion 2020 and the second portion 2024, partially disposed in the same layer as the first portion 2020, and partially disposed in the same layer as the second portion 2024. In the above embodiment, when the curved flexible cover 202 is switched in different states, the first portion 2020 and the second portion 2024 may automatically slide, and the sliding directions of the two portions are opposite; the first shielding sub-layer 2002 and the second shielding sub-layer 2004 are fixedly disposed with the first portion 2020 and the second portion 2024, respectively, so that the purpose of the present application can be achieved more simply without introducing other driving structures.
Further, in the present embodiment, the first shielding sub-layer 2002 is fixedly disposed on a surface of the first portion 2020 facing the second portion 2024, and the second shielding sub-layer 2004 is fixedly disposed on a surface of the second portion 2024 facing the first portion 2020. Before the flexible display module is assembled, the first shielding sub-layer 2002 and the second shielding sub-layer 2004 may be formed on the same side surface of the flexible cover plate 202 to reduce the difficulty of manufacturing the flexible display module. In addition, referring to fig. 3, the light shielding layer 200 further includes a third light shielding sub-layer 2006 fixedly disposed on a side surface of the connection portion 2022 facing the first portion 2020 and the second portion 2024, and the first light shielding sub-layer 2002, the third light shielding sub-layer 2006 and the second light shielding sub-layer 2004 are sequentially connected to each other. The design method can also reduce the process preparation difficulty, and the connecting portion 2022 is positioned at the edge of the non-display area of the flexible display screen 20, so that the purpose of reducing light leakage can be achieved by arranging the third light shielding sub-layer 2006 on the connecting portion 2022.
Alternatively, in the present embodiment, the material of the light shielding layer 200 may be ink, which may be formed on the flexible cover plate 202 by a relatively mature process such as coating. In addition, the light shielding layer 200 may cover the non-display area around the light transmitting area 2000 corresponding to the optical element 4, and the non-display area of the rest may also cover the light shielding layer to reduce light leakage.
Referring to fig. 3 and fig. 4 together, fig. 4 is a schematic top view of an embodiment of the first light holes and the second light holes in fig. 3; wherein the graph (a) in fig. 4 corresponds to the flattened state of the graph (a) in fig. 3, and the graph (b) in fig. 4 corresponds to the bent state of the graph (b) in fig. 3. When switching from the flattened state to the folded state, the first portion 2020 moves in a first direction X1 and the second portion 2024 moves in a second direction X2 opposite to the first direction X1; in the flattened state, as shown in fig. 3 (a) and fig. 4 (a), the first light holes a are offset in the second direction X2 with respect to the second light holes B; in the bent state, as shown in fig. 3 (B) and 4 (B), the first light holes a are offset in the first direction X with respect to the second light holes B. When the flexible display screen 20 is switched from the flattened state to the folded state, the size of the light transmission area defined by the first light transmission hole a and the second light transmission hole B together can be enlarged first and then reduced, and finally the area of the first light transmission area in the flattened state and the area of the second light transmission area in the folded state can be approximate, so that the effects of the optical element 4 in different states are the same.
Preferably, the area of the first light-transmitting region 2000a in the flattened state is equal to the area of the second light-transmitting region 2000b in the folded state. The mode can enable the sizes and the positions of the corresponding light transmission areas of the optical element in different states to be the same, and the using effect of the optical element 4 is the same.
Alternatively, referring again to fig. 3 and 4, upon switching between the flattened state and the folded state, the first portion 2020 and the second portion 2024 are moved by a first distance d1, respectively; the first light-transmitting holes A and the second light-transmitting holes B are identical in shape, the first light-transmitting holes A and the second light-transmitting holes B are runway-shaped, namely, the two ends of the first light-transmitting holes A and the second light-transmitting holes B are circular arcs, and the middle of the first light-transmitting holes A and the middle of the second light-transmitting holes B are straight-line sections. The extending direction of each straight line segment (not labeled) in the first light transmitting hole a and the second light transmitting hole B is parallel to the first direction X1, the length d2 of each straight line segment is the same as the first distance d1, and the first light transmitting area 2000a and the second light transmitting area 2000B are circular. Generally, the light sensing surface of the optical element 4 is circular, and the above-mentioned design manner of the first light-transmitting area 2000a and the second light-transmitting area 2000b being circular can make the collection effect of the optical element 4 better.
In yet another embodiment, referring again to fig. 3, the flexible display 20 further includes at least one first functional film layer 206 positioned at a spaced location between the first portion 2020 and the second portion 2024 of the flexible cover 202; the first functional film 206 closest to the second portion 2024 has a sliding groove 2060 provided on a surface thereof facing the second portion 2024, and the second portion 2024 moves in the sliding groove 2060. The sliding groove 2060 is designed in such a way that the second portion 2024 slides easily under the driving of the first portion 2020, so as to facilitate bending of the flexible display screen 20 without increasing the thickness of the flexible display screen 20.
Referring to fig. 5, fig. 5 is a schematic structural diagram of another embodiment of the flexible display module in fig. 3. In a direction perpendicular to the first shielding sub-layer 2002 to the second shielding sub-layer 2004 (i.e. a direction perpendicular to the first direction X1 or the second direction X2 mentioned in the above embodiments), a surface of the end 2062 of the at least one first functional film layer 206 facing the flexible cover 202 is a cambered surface, and the flexible cover 202 abuts against the cambered surface. This design may facilitate bending of the flexible display 20 and sliding of the flexible cover 202.
Alternatively, referring to fig. 6, fig. 6 is a schematic structural diagram of another embodiment of the flexible display module in fig. 3. In a direction perpendicular to the first to second light-shielding sublayers 2002-2004, there is a gap between the end 2062 of the at least one first functional film layer 206 facing the flexible cover 202 and the flexible cover 202; the flexible display module (not shown in fig. 6) further includes at least one roller 208, which is disposed in the gap, and the flexible cover 202 abuts against a portion of the surface of the roller 208. The design may also facilitate bending of the flexible display 20 and sliding of the flexible cover 202.
In addition, referring to fig. 3 again, at least one of the first functional film layers 206 in the above embodiment includes an optical adhesive layer, and a sliding groove 2060 is disposed on a surface of the optical adhesive layer facing the second portion 2024. Of course, in other embodiments, the at least one first functional film layer 206 may also include an optical adhesive layer and a polarizing layer that are stacked, and the polarizing layer is close to the substrate 204 relative to the optical adhesive layer, and a sliding groove 2060 is disposed on a surface of the polarizing layer facing the second portion 2024. In the above design, the spacing distance between the first portion 2020 and the second portion 2024 is smaller, so that the vertical distance between the first shielding sub-layer 2002 and the second shielding sub-layer 2004 is smaller, thereby reducing the amount of slippage when the flexible display 20, the first shielding sub-layer 2002 and the second shielding sub-layer 2004 are switched in different states.
Optionally, in this embodiment, the flexible display screen 20 may include a substrate 204, an array layer, a light emitting layer, a packaging layer, a touch layer, a polarizing layer, and an optical adhesive layer that are stacked; wherein, the first portion 2020 of the flexible cover 202 may be located on a side of the optical adhesive layer facing away from the polarizing layer, and the second portion 2024 of the flexible cover 202 may be located between the optical adhesive layer and the polarizing layer, or between the polarizing layer and the touch layer. In addition, in order to make the collection effect of the optical element 4 better, the positions of the substrate 204, the array layer, the light emitting layer, the packaging layer, the touch layer, the polarizing layer, the optical adhesive layer and the second portion 2024 corresponding to the optical element 4 are provided with via holes; wherein the via hole on the second portion 2024 coincides with the second light-transmitting hole B. Although the positions of the through holes on the respective film layers will also slide when the flexible display 20 is switched under different states, the size of the light-transmitting area 2000 of the whole flexible display 20 is determined by the light-shielding layer 200 because the light transmittance of the respective film layers is greater than that of the light-shielding layer 200.
Preferably, in the present embodiment, as shown in fig. 3 (a), the sizes of the via holes on the substrate 204, the array layer, the light emitting layer, the packaging layer, the touch layer, the polarizing layer, the optical adhesive layer and the second portion 2024 are larger than the size of the light-transmitting area 2000 in different states; the design may reduce the probability of blocking and absorbing light by the substrate 204, the array layer, the light emitting layer, the packaging layer, the touch layer, the polarizing layer, the optical glue layer, and the second portion 2024, so as to improve the collection effect of the optical element 4. In addition, since the film layer in the inner layer has smaller offset when switching in different states, the size of the substrate 204 and the vias on the film layer near the substrate 204 may be smaller than the size of the vias on the film layer near the flexible cover 202; for example, the via on at least one first functional film 206 between the first portion 2020 and the second portion 2024 has a first size, the via on the second portion 2024 has a second size, the via on the remaining film between the substrate 204 and the second portion 2024 has a third size, the via on the substrate 204 has a fourth size, wherein the first size and the second size are greater than the third size and the fourth size, and the first size is greater than or equal to the second size, and the fourth size is greater than or equal to the third size.
In addition, in the above embodiments, the first portion 2020 and the second portion 2024 that are connected to each other bear and move the first shielding sub-layer 2002 and the second shielding sub-layer 2004; of course, in other embodiments, the first portion 2020 and the second portion 2024 that carry and move the first shielding sub-layer 2002 and the second shielding sub-layer 2004 may be disconnected from each other; taking the bending manner in fig. 3 as an example, when the flexible display 20 is switched from the flattened state to the bending state, the first portion 2020 drives the first shielding sub-layer 2002 to move leftwards; when the second portion 2024 is bent and no other external force acts, the second portion 2024 also drives the first shielding sub-layer 2002 to move leftwards; in order to achieve the same effect as in fig. 3, a driving component may be additionally introduced to be fixedly connected to the second portion 2024, so as to drive the second portion 2024 to move in a direction opposite to the first portion 2020 in the bent state.
In addition, in the above-described embodiments, the light shielding layer 200 includes two light shielding sublayers, the first light shielding sublayer 2002 and the second light shielding sublayer 2004, respectively. In other embodiments, the light shielding layer 200 may be only one layer, and the light shielding layer 200 may be made of some materials with light shielding performance and elasticity, such as silica gel with black pigment. When the flexible display 20 is switched from the flattened state to the folded state, the single-layer light shielding layer moves along the first direction when no other external force acts due to the folding action; at this time, a driving component can be additionally introduced and fixedly connected with the shading layer and used for driving the shading layer to move along a second direction opposite to the first direction during state switching; the action of force on the single-layer shading layer during state switching is counteracted by the driving component, so that the position of the light transmitting area on the single-layer shading layer relative to the optical element is kept unchanged.
The foregoing description is only illustrative of the present application and is not intended to limit the scope of the application, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present application.
