The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
A display screen assembly and an electronic device according to an embodiment of the present application are described below with reference to fig. 1 to 17.
As shown in fig. 1, 2, 3 and 4, some embodiments of the present application provide a display screen assembly 100 that can be switched between an expanded state and a contracted state by drawing or folding. As shown in fig. 3 and 4, the display screen assembly 100 includes a flexible cover 102 and a flexible display panel 104 that cooperate together. The flexible cover plate 102 covers the light emitting side of the flexible display panel 104; as shown in fig. 5 and 6, the flexible display panel 104 includes a support layer 110 and a functional layer 112, a plurality of first stress grooves 108 are disposed side by side on a side of the support layer 110 facing away from the functional layer 112, and the flexible display panel 104 is capable of bending and deforming at least at any one of the first stress grooves 108.
Further, as shown in fig. 5 and 6, the functional layer 112 is located between the support layer 110 and the flexible cover plate 102 and can display pictures during operation; the support layer 110 is located below the functional layer 112 and can support the functional layer 112 during use, ensuring a stable position of the functional layer 112. In addition, a side of the support layer 110 facing away from the functional layer 112 is provided with a plurality of first stress grooves 108 distributed side by side, and the flexible display panel 104 can be subjected to bending deformation at any one of the first stress grooves 108, and an extending direction of the first stress groove 108 coincides with a bending axis of the flexible display panel 104. In this way, when the flexible display panel 104 is bent, the bending stress can be eliminated or reduced by the first stress groove 108, so that the flexible display panel 104 is easier to bend, and the bending degree of the flexible display panel 104 is increased, thereby avoiding the occurrence of the situation that the flexible display panel 104 is broken.
In the flexible display panel 104, the side where the functional layer 112 is provided is a light-emitting side of the flexible display panel 104, and the side where the support layer 110 is provided is a backlight side of the flexible display panel 104. In actual use, a user tends to bend the flexible display panel 104 towards the backlight side and expose the light emitting side of the flexible display panel 104, which results in greater stress on the side of the support layer 110 facing away from the functional layer 112. Therefore, according to the present disclosure, the first stress groove 108 is disposed on a side of the support layer 110 away from the functional layer 112, so that stress generated when the support layer 110 is bent can be reduced or eliminated to the greatest extent, and a service life of the support layer 110 is further prolonged.
It should be noted that the flexible display panel 104 itself has a certain flexibility, and each position of the flexible display panel 104 can be subjected to bending deformation. That is, the flexible display panel 104 may be bent and deformed at a position where the first stress groove 108 is disposed, or may be bent and deformed at a position where the first stress groove 108 is not disposed. Accordingly, the flexible cover 102 itself has a certain flexibility, and each position of the flexible cover 102 can be subjected to bending deformation.
Therefore, the present application provides a plurality of first stress grooves 108 distributed side by side on the flexible display panel 104, which can eliminate or reduce the stress generated when the display screen assembly 100 is bent and folded, and can achieve a small radius folding and curling, and at the same time, the ability of the display screen assembly 100 to fold and bend and deform.
As a possible implementation, there is a gap 106 between the flexible cover sheet 102 and the flexible display panel 104. The flexible display panel 104 may be protected by the flexible cover 102, and the flexible cover 102 may be thickened to improve the surface impact resistance of the display screen assembly 100. Meanwhile, because the gap 106 exists, a certain buffer distance exists between the flexible cover plate 102 and the flexible display panel 104, the phenomenon of poor folding caused by inconsistent bending rates of the flexible cover plate 102 and the flexible display panel 104 is avoided, and the flexible cover plate 102 cannot be directly applied to the flexible display panel 104 when being collided. In addition, when the flexible cover plate 102 is damaged due to collision, the flexible cover plate 102 can be detached and replaced independently, which is more convenient and economical.
As a possible implementation, as shown in fig. 5, for the flexible display panel 104, the side provided with the functional layer 112 is the light emitting side of the flexible display panel 104, and the side provided with the support layer 110 is the backlight side of the flexible display panel 104. In actual use, a user tends to bend the flexible display panel 104 towards the backlight side and expose the light emitting side of the flexible display panel 104, which results in greater stress on the side of the support layer 110 facing away from the functional layer 112. Therefore, according to the present disclosure, the first stress groove 108 is disposed on a side of the support layer 110 away from the functional layer 112, so that stress generated when the support layer 110 is bent can be reduced or eliminated to the greatest extent, and a service life of the support layer 110 is further prolonged.
As a possible implementation, as shown in fig. 5, the functional layer 112 includes a plurality of light emitting device units 114 used in cooperation. The light emitting device units 114 are arranged at intervals along the distribution direction of the first stress grooves 108, so that an interval 116 exists between two adjacent light emitting device units 114, and the functional layer 112 can be bent and deformed at the position of any interval 116. Thus, the interval 116 between two adjacent light emitting device units 114 is used as the bending position of the functional layer 112, so that the light emitting device units 114 are not damaged when the display screen assembly 100 is bent, and the service life of the light emitting device units 114 is further ensured.
As one possible embodiment, as shown in fig. 5, in the thickness direction of the flexible display panel 104, the first stress groove 108 corresponds to a position of the space 116 between two adjacent light emitting device units 114. That is, it is ensured that the bending position of the functional layer 112 is matched with the bending position of the support layer 110, and when the flexible display panel 104 is bent, the bending position of the functional layer 112 is ensured to be bent together with the bending position of the support layer 110, thereby preventing any one of the support layer 110 and the functional layer 112 from being damaged.
As a possible implementation, as shown in fig. 6, the flexible display panel 104 further includes a light shielding layer 120. The light shielding layer 120 is located between the flexible cover plate 102 and the light emitting device unit 114 and covers the top of the light emitting device unit 114, and a plurality of second stress grooves 118 distributed side by side are arranged on one side of the light shielding layer 120 facing away from the light emitting device unit 114.
The first stress groove 108 and the second stress groove 118 are located on two opposite sides of the flexible display panel 104, the first stress groove 108 is located on a backlight side of the flexible display panel 104, and the second stress groove 118 is located on an occurrence side of the flexible display panel 104, and it is ensured that the extending directions of the first stress groove 108 and the second stress groove 118 are consistent, and are consistent with the bending axis of the flexible display panel 104, and the distribution directions of the plurality of first stress grooves 108 and the plurality of second stress grooves 118 are consistent.
Thus, when the flexible display panel 104 is bent, the bending stress generated on the backlight side of the flexible display panel 104 can be eliminated or reduced through the first stress groove 108, and the bending stress generated on the light emitting side of the flexible display panel 104 can be eliminated or reduced through the second stress groove 118, so that the first stress groove 108 and the second stress groove 118 are matched with each other, the bending degree of the flexible display panel 104 is further improved, and the flexible display panel 104 is prevented from being broken.
As one possible embodiment, as shown in fig. 6, in the thickness direction of the flexible display panel 104, the first stress groove 108, the second stress groove 118, and the space 116 between two adjacent light emitting device units 114 correspond in position. That is, the bending positions of the light-shielding layer 120, the supporting layer 110, and the interval 116 between two adjacent light-emitting device units 114 are ensured to coincide. When the flexible display panel 104 is bent, the bending position of the light shielding layer 120 and the bending position of the support layer 110 are ensured to be bent together, so that any one of the support layer 110 and the functional layer 112 is prevented from being damaged.
As a possible embodiment, as shown in fig. 7, the first stress groove 108 may be filled with a supporting layer 110; as shown in fig. 8, first stress groove 108 may be disposed only in a partial region of support layer 110. Specifically, when a local portion of handle layer 110 is provided with first stress groove 108, it should be ensured that first stress groove 108 is disposed at a position where handle layer 110 is frequently bent, so as to ensure a service life of the portion of handle layer 110.
As one possible embodiment, as shown in fig. 9, the second stress groove 118 may be fully distributed over the light-shielding layer 120, or may be provided only in a partial region (not shown) of the light-shielding layer 120. Specifically, when the second stress groove 118 is locally disposed on the light shielding layer 120, it should be ensured that the second stress groove 118 is disposed at a position where the light shielding layer 120 is frequently bent, so as to ensure the service life of the portion of the light shielding layer 120.
As one possible implementation, as shown in fig. 10, the gap 106 between the flexible cover sheet 102 and the flexible display panel 104 may be continuous; as shown in fig. 11 and 12, the gap 106 between the flexible cover sheet 102 and the flexible display panel 104 may also be segmented. That is, the gap 106 may be filled between the flexible cover 102 and the flexible display panel 104, or the gap 106 may be provided only in a partial region between the flexible cover 102 and the flexible display panel 104, and the remaining portion is filled with the connection glue 122. Wherein, OCA glue can be used as the connection glue 122.
As a possible embodiment, as shown in fig. 13, 14 and 15, the display screen assembly 100 further includes a receiving member and a driving member (not shown). The receiving member may be configured to receive the flexible cover 102 and/or the flexible display panel 104, and the driving member is connected to the flexible cover 102 and the flexible display panel 104 and configured to stretch the flexible cover 102 and the flexible display panel 104 to switch the display screen assembly 100 between the extended state and the retracted state.
Specifically, when the display screen assembly 100 is in the retracted state, the flexible cover 102 is in the rolled state, and the flexible display panel 104 is in a space enclosed by the flexible cover 102; when the display screen assembly 100 is required to be in the unfolded state, the flexible cover plate 102 and the flexible display panel 104 are stretched by the driving member, so that the flexible cover plate 102 and the flexible display panel 104 are laid out and unfolded.
As a possible embodiment, as shown in fig. 13, the receiving member includes a first reel 124, and the flexible display panel 104 is wound around the first reel 124. In this way, the first roller 124 can accommodate the flexible display panel 104 by at least twice, i.e. the area of the display screen assembly 100 in the extended state is at least twice as large as that in the retracted state. Moreover, when the driving member stretches the flexible display panel 104, the first reel 124 can roll along with the flexible display panel, so as to ensure smooth stretching.
As a possible implementation manner, as shown in fig. 14, the storage member includes two first reels 124, two first reels 124 are located on two opposite sides, and the storage amount of the flexible display panel 104 is three times that of the flexible display panel, and in addition, the storage member further includes a second reel 126, the second reel 126 is located on the same side as one of the first reels 124, and the flexible cover 102 is wound around the second reel 126. In this way, the second roller 126 can accommodate the flexible display panel 104 by at least three times, i.e., the area of the display screen assembly 100 in the unfolded state is at least two times that in the folded state. Moreover, when the driving member stretches the flexible display panel 104, the second reel 126 can roll along with the flexible display panel, so that smooth stretching is ensured.
As a possible embodiment, as shown in fig. 15, the receptacle includes a receptacle 128. The storage chamber 128 is located in the space enclosed by the flexible cover plate 102 and located at one end of the display screen assembly 100. When the display screen assembly 100 is in the retracted state, the flexible display panel 104 is folded to be received in the receiving compartment 128; when it is desired to unfold the display screen assembly 100, the flexible display panel 104 in a folded state, which is received in the receiving compartment 128, is stretched by the driving member.
As a possible implementation, as shown in fig. 4 and 5, the functional layer 112 further includes a driver module substrate layer 130 and a driver circuit module layer 132 used in cooperation. The driving module substrate layer 130 is located between the support layer 110 and the light emitting device units 114, and the driving circuit module layer 132 is disposed on the substrate layer and supports the light emitting device units 114 on the driving circuit module layer 132. In this way, the driving module base layer 130, the driving circuit module layer 132, the light-emitting device unit 114, and the light-shielding layer 120 cooperate with each other, thereby ensuring that the functional layer 112 displays a picture for a user.
As shown in fig. 17, an embodiment of the present application provides an electronic device including the display screen assembly 100 according to the above embodiment. Thus, all of the benefits of the display screen assembly 100 described above are not discussed herein.
Specifically, the electronic device may be: cell-phone, smart watch, panel computer, computer etc..
In addition, as shown in fig. 17, the electronic device further includes a main body 202, and a placement hole 136 is provided in the main body 202, and the placement hole 136 can be used for accommodating a stylus 204.
In a specific embodiment, the current mobile phone screen is generally a front single-screen mobile phone, a double-screen mobile phone, a folding screen mobile phone, a stretching screen mobile phone, and the like, and the flexible folding stretching mobile phone can expand the display area under a limited volume, so that a user can obtain a larger display interface. However, in order to reduce the bending radius of the existing flexible foldable and stretchable display screen assembly, the thickness of each layer of the display screen assembly needs to be reduced to facilitate bending and folding. The surface cover plate is generally made of glass or transparent resin (CPI), etc., and the surface cover plate needs to be hardened and thickened for scratch resistance, collision resistance, etc., the thickness and hardness are increased, the bending radius and the foldable type are deteriorated, and the thickness and the bending of the cover plate are a pair of spear shields. The bending area has obvious fold problem due to the fact that the inner and outer bending radiuses are not consistent, and meanwhile the screen is easy to damage at present, the whole screen is replaced after the screen is damaged, and replacement cost is high.
As shown in fig. 3 and 4, in the display screen assembly 100 of the present application, a folding structure design is added to the flexible display panel 104 to achieve a smaller bending radius, and meanwhile, the flexible cover plate 102 and the flexible display panel 104 adopt a separated design, so that the flexible cover plate 102 can be thickened to improve the surface impact resistance, and the poor folding caused by the inconsistent bending rates of the flexible cover plate 102 and the flexible display panel 104 after the separation is avoided. Under the condition that the flexible cover plate 102 is damaged, the flexible cover plate 102 can be replaced independently, and the method is more convenient and economical.
In addition, as shown in fig. 5 and fig. 6, the flexible display panel 104 in the present disclosure adopts a slotted design (the first stress slot 108 and the second stress slot 118), so as to eliminate bending stress and facilitate bending and stretching; the flexible cover plate 102 and the flexible display panel 104 are designed in a separated mode, so that the influence on the flexible display panel 104 is greatly reduced when the flexible cover plate 102 is impacted by external force; the flexible display panel 104 that is pliable may be a multi-layer folding design.
In one embodiment, the display assembly 100 may be flat and designed for placement inside a cell phone. Wherein, display screen subassembly 100 includes flexible apron 102 and flexible display panel 104, is provided with clearance 106 between flexible apron 102 and the flexible display panel 104, and the size L of clearance 106 can be according to the effect setting 0.001mm to 1mm of demand, can set for 0.1mm generally.
As shown in fig. 5 and 6, the flexible display panel 104 includes a light-shielding layer 120, a light-emitting device unit 114, a driving circuit module layer 132, a driving module substrate layer 130, and a support layer 110. The light-shielding layer 120 may be a polarizer, a color filter layer, or a thin film encapsulation layer; the light emitting device unit 114 may be an organic light-emitting diode (OLED) or a micro inorganic light-emitting diode (micro LED); a space 116 exists between two adjacent light emitting device units 114, and the space 116 can be filled with resin and the like; the support layer 110 is cut to form the first stress groove 108, and the light shielding layer 120 is patterned to form the second stress groove 118, so that the shape can be designed as required to eliminate the back stress when the flexible display panel 104 is bent and curled, such as a semicircle, a triangle, a trapezoid, and the like, which is easy to bend the whole flexible display panel 104.
As shown in fig. 6 and 9, the light-shielding layer 120 may be formed by partially forming the second stress groove 118, or by forming the second stress groove 118 on the entire light-shielding layer 120, but the first stress groove 108 is opposite to the second stress groove 118, and the first stress groove 108 is located below the space 116 between two adjacent light-emitting device units 114, so as to avoid damage to the light-emitting device units 114. In particular, due to the design of the second stress groove 118 on the light shielding layer 120, the thickness of the entire flexible display panel 104 is further reduced to achieve the reduction of the bending radius.
Further, a third stress groove may also be provided on the drive module base material layer 130. A fourth stress groove may also be provided in the resin filling the space 116 between two adjacent light emitting device units 114.
Specifically, the flexible cover 102 and the flexible display panel 104 are accommodated in the following manners, including but not limited to:
