Fig. 1 is a cross-sectional view illustrating a bezel area of a display module according to an exemplary embodiment. Fig. 2 is a schematic structural diagram of a display module according to an exemplary embodiment.

As shown in fig. 1 and 2, in an embodiment of the disclosure, the display module 100 may be divided into a display area a1 and a non-display area a2 surrounding the display area a 1. The non-display area a2 constitutes a frame area of the display module 100. In an embodiment of the present disclosure, as shown in fig. 1, the display module 100 may include: a first glass substrate 101; an encapsulation layer 103, a first surface (e.g., an upper surface in fig. 1) of the encapsulation layer 103 being attached to one side edge of the first glass substrate 101; the groove region includes a first groove 104, which is disposed on the surface of the first glass substrate 101 and located in a region where the first glass substrate 101 and the first surface of the encapsulation layer 103 are bonded. In the present disclosure, the groove region may be along a periphery of a surface of the first glass substrate 101 (e.g., a lower side surface of the first glass substrate 101 in fig. 1) or several sides thereof, or may be an entire region where the encapsulation layer 103 is adhered to the first glass substrate 101. The groove region may include a first groove 104, and may be disposed in a region where the encapsulation layer 103 is attached to the first glass substrate 101. Through setting up first recess 104, can receive external force at display module assembly 100 and strike, if fall or under the condition such as collision, the first recess 104 of stress direction is let out the power through first recess 104, and cracked position concentrates on the recess region, reduces the risk of diffusion display module assembly 100 display area A1, and the protection screen center is not damaged, also can avoid the damage of stress to the circuit simultaneously.

As shown in fig. 1, the display module 100 may further include: a first glass substrate 101 and a second glass substrate 106 disposed below the first glass substrate 101. The first glass substrate may be a glass cover plate.

As shown in fig. 1, an encapsulation layer 103 is provided between a first glass substrate 101 and a second glass substrate 106. A first surface (e.g., an upper surface in fig. 1) of the encapsulation layer 103 is attached to one side edge of the first glass substrate 101, and the first surface of the encapsulation layer 103 is in surface contact with the first glass substrate 101. The second glass substrate 106 is attached to a second surface (e.g., the lower surface in fig. 2) of the encapsulation layer 103, which is the surface of the encapsulation layer 103 opposite to the first surface, and also in surface contact therewith.

As described above, the edge regions of the first glass substrate 101 and the second glass substrate 106 are encapsulated by the encapsulation layer 103. Can effectively obstruct moisture and oxygen through setting up encapsulation layer 103, guarantee display module's life-span, not only technology is simpler, can also be suitable for big-and-middle-sized display module, can carry out the volume production moreover. However, due to the encapsulation layer 103, stress concentration may be formed at the edges of the first glass substrate 101 and the second glass substrate 106, which may result in poor performance of the display module against falling and collision, and when a certain degree of impact is received, the display module may be easily cracked, which may result in cracking of the central region including the display area a1 of the display module, and damage to the circuits including the driving circuit 102 in fig. 1.

Further, encapsulation layer 103 can be through the encapsulation of frat (glass frit), glass encapsulation layer promptly, encapsulates through the butt fusion glass frit, also can be more obvious when realizing better encapsulated effect and form stress concentration at the edge of first glass substrate 101 and second glass substrate 106, under the condition that adopts the encapsulation of frat, through setting up the recess region to stress when assaulting carries out the earial relief, and the effect of the central zone of protection display module assembly 100 and circuit is more obvious.

The width W2 of the encapsulation layer 103 along the width direction of the display module 100 may be set according to the size of the display module. For example, in one embodiment, the width W2 of the encapsulation layer 103 along the width direction of the display module 100 may be 0.49 mm.

As shown in fig. 1, the encapsulation layer 103 is disposed on the outer side between the first glass substrate 101 and the second glass substrate 106. On the inner side between the first glass substrate 101 and the second glass substrate 106, a driving circuit 102, such as a Gate Driver on Array (GOA) circuit or the like, may be disposed. When the display module 100 receives an impact, the driving circuit 102 may be damaged due to stress.

As shown in fig. 1, the driving circuit 102 may be disposed between the first glass substrate 101 and the second glass substrate 106 and within the encapsulation area of the encapsulation layer 103, with the driving circuit 102 spaced apart from the encapsulation layer 103. Referring to fig. 2, the encapsulation layer 103 is disposed outside the driving circuit 102 along the thickness direction of the display module 100.

As shown in fig. 1, the groove region may include a first groove 104 opened on a surface of the first glass substrate 101, such as a lower surface of the first glass substrate 101 in fig. 1. The first groove 104 may be disposed in a region where the first glass substrate 101 is attached to the first surface of the encapsulation layer 103. In other embodiments, a second groove 105 may be formed on a surface of the second glass substrate 106, such as the upper surface of the second glass substrate 106 in fig. 1. The second groove 105 may be disposed in a second surface bonding area of the second glass substrate 106 and the encapsulation layer 103. The first groove 104 and the second groove 105 may be formed on the surfaces of the first glass substrate 101 and the second glass substrate 106 by laser or other methods. Because the position of the encapsulation layer 103 can generate stress concentration in the display module 100 in the collision process, the groove formed in the corresponding position can prevent the middle area of the display module 100 from being damaged and can also prevent circuits such as the driving circuit 102 from being damaged by the leakage force of the groove at the edge of the display module 100 in the collision process.

The first groove 104 and the second groove 105 may be disposed at an edge, such as a top edge, of a side plate of the display module 100, so as to protect the display module from collision in the direction; it is also possible to arrange at the position of the edges of the sides, that is, the first groove 104 is arranged at the edge of the sides of the first glass substrate 101 and the second groove 105 is arranged at the edge of the sides of the second glass substrate 106, thereby protecting the impact in multiple directions.

In an embodiment of the present disclosure, the first groove 104 may be continuously disposed at an edge position of the first glass substrate 101, for example, may extend along one side edge of the first glass substrate 101, and the first groove is disposed in the pasting region of the encapsulation layer 103. In other embodiments, the first grooves 104 may also be disposed at intervals at the edge of the first glass substrate 101, that is, a plurality of sections of the first grooves 104 are formed at the edge of the side of any one of the first glass substrates 101, and the distributed first grooves 104 can also relieve stress at different positions.

Similarly, in an embodiment of the present disclosure, the second groove 105 may be continuously disposed at an edge position of the second glass substrate 106. In other embodiments, the second grooves 105 may also be disposed at intervals at the edge of the second glass substrate 106.

Some of the impacts to the display module 100 are caused by the falling, and are often more likely to be applied to positions near four corners of the display module 100, such as the R-corner arc region of the first glass substrate 101. In some embodiments of the present disclosure, the groove region further includes a third groove (not shown) located in the R-corner arc region of the first glass substrate 101, wherein the width of the third groove is greater than the width of the first groove 104, and/or the depth of the third groove is greater than the depth of the first groove 104. In this embodiment, third grooves are formed in one or more R-corner arc regions of the first glass substrate 101, that is, positions near four corners of the display module 100, and the third grooves may be separately disposed or may be disposed to penetrate the first grooves 104. In order to perform the force leakage in the region where the collision is more likely, the width of the third groove may be made wider than the width of the first groove 104, and the depth of the third groove may be made deeper than the depth of the first groove 104, so that the force leakage can be better when the collision is applied at the corner position.

Similarly, a fourth groove may be correspondingly disposed at the position of the R-angle arc region of the second glass substrate 106, wherein the width of the fourth groove is greater than the width of the second groove 105, and/or the depth of the fourth groove is greater than the depth of the second groove 105.

As shown in fig. 1, the first groove 104 and the second groove 105 are symmetrically disposed along the encapsulation layer 103 in the thickness direction of the first glass substrate 101. That is, in the thickness direction of the first glass substrate 101, the openings of the first groove 104 and the second groove 105 are opposite to each other, and are respectively disposed on the first glass substrate 101 and the second glass substrate 106, and located on the upper and lower sides of the encapsulating layer 103. The first glass substrate 101 and the second glass substrate 106 can be better protected by providing the first groove 104 and the second groove 105, respectively.

As shown in fig. 1, in this embodiment, the cross-sectional shapes of the first groove 104 and the second groove 105 may be formed in a rectangular shape. The present disclosure is not limited thereto, and the sectional shapes of the first groove 104 and the second groove 105 may be formed in a triangular shape, a trapezoidal shape, an arc shape, or the like. The first groove 104 and the second groove 105 may be formed in the same cross-sectional shape or different cross-sectional shapes.

In forming the first glass substrate 101 and the second glass substrate 106, the first groove 104 and the second groove 105 may be formed by laser etching. Therefore, the formation process of the first and second grooves 104 and 105 is very simple.

In some embodiments, the first groove 104 may be a plurality of grooves, and the plurality of grooves are disposed in parallel on the first glass substrate 101. Also, the plurality of first grooves 104 may extend in a longitudinal direction or a lateral direction or a diagonal direction of the first glass substrate 101. The second groove 105 may be plural, and the plural second grooves 105 are arranged in parallel with each other. Also, the plurality of second grooves 105 may extend in a longitudinal direction or a lateral direction or a diagonal direction along the second glass substrate 106. In this embodiment, the longitudinal direction refers to the long side direction of the first glass substrate 101 or the second glass substrate 106, i.e., the direction from the bottom to the top of the terminal; the lateral direction refers to a short side direction of the first glass substrate 101 or the second glass substrate 106, i.e., a left-right width direction of the terminal; the oblique direction is a direction forming a certain included angle with the side length of the first glass substrate 101 or the second glass substrate 106. Stress can be further dispersed by arranging the plurality of first grooves 104 and the plurality of second grooves 105, and the glass substrate can be protected. In some embodiments, the projections of the first groove 104 and the second groove 105 in the thickness direction of the first glass substrate 101 may be staggered and do not overlap with each other, so that the impact force in different directions can be released, the stress can be dispersed, and the glass substrate can be protected.

As shown in fig. 1, the width W1 of the first glass substrate 101 and the second glass substrate 106 in the frame area of the display module 100 along the width direction of the display module 100 may be 0.9 mm. The width W2 of the encapsulation layer 103 may be 0.49 mm. The width of the driving circuit 102 may be 0.25mm at W3. A certain distance is reserved between the driving circuit 102 and the display area a1, and a gap of about 0.1mm is also reserved between the driving circuit 102 and the encapsulation layer 103.

The width W4 of the first and second grooves 104 and 105 may be in the range of 0.1mm-0.15mm, and the height H1 of the first and second grooves 104 and 105 may be in the range of 0.05mm-0.1 mm.

The above is only an exemplary embodiment, for example, in an embodiment, the ratio of the width W4 of the first groove 104 to the width W2 of the encapsulation layer 103 is between 15% and 80%; the ratio of the width W4 of the second groove 105 to the width W2 of the encapsulation layer 103 is between 15% and 80%.

In addition, as shown in fig. 1, the first recess 104 and the second recess 105 may be disposed at the center of the packaging layer 103 in the width direction, and since the packaging layer 103 needs to package the display module 100, the first recess 104 and the second recess 105 are not too close to the outer edge of the packaging layer 103.

In an embodiment, a ratio of a spacing between an outer edge of the first groove 104 and an outer edge of the encapsulation layer 103 relative to the width W2 of the encapsulation layer 103 may be in a range of 30% -60%. For the same reason, the ratio of the distance between the outer edge of the second groove 105 and the outer edge of the encapsulation layer 103 relative to the width W2 of the encapsulation layer 103 may also be in the range of 30% -60%. Therefore, the first groove 104 and the second groove 105 can be prevented from being too close to the outer side edge of the packaging layer 103 to sacrifice the packaging effect of the packaging layer 103.

As described above, in the case of sealing with glass paste, the main material of the glass paste is glass frit, and since the glass frit has a high hardness, when the display module 100 is dropped and receives stress impacts of forces F1 and F2 as shown in fig. 1, stress is mainly concentrated on the sealing layer 103, and thus, in the case of receiving the stress impacts, in the conventional display module, cracks CR are generally generated from the sealing layer 103, and then the cracks are spread to other positions of the display module.

However, in the embodiment of the present disclosure, the first groove 104 and the second groove 105 are formed on the first glass substrate 101 and the second glass substrate 106 by laser etching. When the display module 100 falls and receives stress impact of forces F1 and F2 as shown in fig. 1, the first groove 104 and the second groove 105 act as a relief groove and can absorb the stress impact, so that unlike the prior art, in the display module 100 of the embodiment of the present disclosure, generation of the crack CR is limited.

Further, when the display module 100 is subjected to stress impact by the forces F1 and F2, the first groove 104 and the second groove 105 can guide the stress to be discharged from the first groove 104 and the second groove 105, thereby reducing the stress intensity on the encapsulation layer 103. Therefore, compare with prior art, need not increase the width of the marginal encapsulated layer of display module assembly 100, only through setting up first recess 104 and second recess 105, can reduce the garrulous screen risk that the stress that concentrates on the encapsulated layer when display module assembly falls the atress and lead to, not only can realize super narrow frame, can also effectively reduce garrulous screen risk.

When the display module 100 falls, as shown in fig. 1, the force applied to the display module 100 may be the direction of the force F1 or the direction of the force F2. However, regardless of the direction of the stress, the stress caused by the falling will be released from the first groove 104 and the second groove 105 formed on both sides of the encapsulation layer 103. Therefore, in this embodiment, the first groove 104 and the second groove 105 are disposed above and below the encapsulation layer 103, so that when the display module falls, the stress concentration point F3 and the stress concentration point F4 guide the force, and the crack CR is limited in the frame region and does not reach the display region a1, thereby protecting the circuit of the driving circuit 102 from being damaged, and greatly reducing the risk of the screen display region a1 being damaged due to the falling of the display module.

However, the present disclosure is not limited thereto, and since the cover glass is generally used as the outermost glass plate and is easily impacted by an external force, the first groove 104 may be formed only on the first glass substrate 104, so as to relieve the external force applied to the first glass substrate 104, thereby reducing the screen shattering phenomenon of the first glass substrate 104.

However, the present disclosure is not limited thereto, and the second glass substrate 106 is more expensive to repair when it is broken than the outermost first glass substrate 104, and thus, the second groove 105 may be formed only on the second glass substrate 106 as a relief groove to guide an external force applied to the second glass substrate 106, thereby reducing the screen breakage phenomenon of the second glass substrate 106.

When the encapsulation layer 103 is used for encapsulation, the encapsulation layer 103 may enter all or part of the first groove 104 or the second groove 105 due to glue overflow. Even if part of the packaging layer 103 or the whole packaging layer 103 exists in the first groove 104 and the second groove 105, the first groove 104 and the second groove 105 can still function as a force release groove, force can be concentrated in the first groove 104 and the second groove 105 and can break along the first groove 104 and the second groove 105, the forming range of the crack CR is limited, and the screen breaking phenomenon is effectively prevented.

As shown in fig. 2, the packaging layer 103 is formed on the periphery of the driving circuit 102, and the first groove 104 and the second groove 105 are also formed on the periphery of the trace of the driving circuit 102. Therefore, when the display module is dropped and stressed, the stress is broken along the first groove 104 and the second groove 105, and the crack CR is localized in the encapsulation layer 103 as shown in fig. 1. As shown in fig. 1, a certain space is formed between the encapsulation layer 103 and the driving circuit 102, so that even if a crack CR is generated in the encapsulation layer 103, the crack CR is not transmitted to the circuit of the driving circuit 102, so that the driving circuit 102 can be protected from being damaged, and the risk of the crack CR falling to cause the breakage of the display area a1 is greatly reduced because the crack CR is limited in the frame area and does not reach the display area a 1.

As described above, the embodiments of the present disclosure are not limited to the hard-screen OLED display module, but may also be applied to the hard-screen LCD display module.

The embodiment described above is merely an example, and various modifications can be made in the present disclosure. For example, in the above embodiment, the first groove 104 and the second groove 105 are provided to completely face each other in the thickness direction of the display module 100, but may be provided to be shifted in the width direction.

In the above embodiment, the first groove 104 and the second groove 105 are both formed as rectangular grooves having the same size, but the present disclosure is not limited thereto, and the first groove 104 and the second groove 105 may be formed as rectangular grooves having different sizes. In another embodiment, the first groove 104 and the second groove 105 may also be formed in different shapes from each other. For example, the first groove 104 is formed as a rectangular groove, and the second groove 105 is formed as a fan-shaped groove.
