As shown in fig. 1-3, one embodiment of the present application provides a screen assembly 100, which includes a glass panel 10, a frame 20, a support bar 30, an adhesive member 40 and a bracket 50, wherein the support bar 30 is mounted on the frame 20, the adhesive member 40 is disposed at an end of the support bar 30 facing the glass panel 10, and the bracket 50 is mounted on the support bar 30.

The frame 20 includes a plurality of connected frame strips 21, the frame strips 21 include a protrusion 211 for carrying the glass panel 10, and the protrusion 211 of the plurality of frame strips 21 collectively carries the glass panel 10. Further, the frame strip 21 further includes a protecting portion 212 connected to the protruding portion 211, the protruding portion 211 is protruding with respect to the protecting portion 212, and the protecting portion 212 is used for enclosing a side end of the glass panel 10 to play a role of protection. It should be understood that the number of the frame strips 21 is determined according to the shape of the glass panel 10, for example, the shape of the glass panel 10 is rectangular, and the number of the frame strips 21 may be four, and the four frame strips 21 are connected end to form the rectangular frame 20.

The supporting bar 30 is mounted to the protrusion 211, and the supporting bar 30 is used to carry the edge of the glass panel 10. The connection between the support bar 30 and the protrusion 211 is not limited, and may be by glue bonding, or may be by a connection member such as a screw, or may be by other means. In this embodiment, the supporting bar 30 is provided with a threaded hole, the protruding portion 211 is provided with a relief hole, and a screw passes through the relief hole and is in threaded connection with the threaded hole, so as to realize connection between the supporting bar 30 and the protruding portion 211.

The end of the supporting bar 30 facing away from the protruding portion 211 is provided with an adhesive member 40, and the adhesive member 40 adheres the glass panel 10 and the supporting bar 30, so that the glass panel 10 is indirectly connected with the frame 20. The direction of the bonding member 40 toward the glass panel 10 is defined as a first direction Z.

Referring to fig. 4, a bracket 50 is mounted to the support bar 30, and the bracket 50 is used to support the glass panel 10. In this embodiment, the bracket 50 includes a connecting portion 51 and an extension portion 52, the connecting portion 51 is connected to the supporting bar 30, and the extension portion 52 is located outside the protruding portion 211 and is deformed by being pressed by the glass panel 10. Wherein the outer extension 52 is configured such that when the glass panel 10 is separated from the support bar 30, the outer extension 52 resumes deformation, and the dimension of the outer extension 52 in the first direction Z is greater than the dimension of the support bar 30 in the first direction Z, the outer extension 52 can abut the glass panel 10 such that the edge of the glass panel 10 has a gap with the support bar 30 in the first direction Z. In this way, in the assembly process, because the gap exists between the outer extension 52 and the support bar 30 under the abutment of the glass panel 10, the risk that the ink coated on the edge of the glass panel 10 is scraped by the support bar 30 in the process of moving the glass panel 10 is reduced, and the subsequent normal use of the screen assembly 100 is ensured.

It should be appreciated that the screen assembly 100 has limited movement of the glass panel 10 in the first direction Z during assembly, the frame strips 21 of the frame 20 are provided with an assembly gap between each other in the XY plane for easy adjustment, when the glass panel 10 is placed on the frame 20, the brackets 50 provided on the plurality of frame strips 21 bear against the glass panel 10 together to provide a gap between the glass panel 10 and the support strips 30, and then the glass panel 10 is moved in the XY plane, and the risk of ink at the edges of the glass panel 10 being scratched by the support strips 30 during movement due to the gap between the glass panel 10 and the support strips 30 can be reduced. When the glass panel 10 is adjusted to a proper position, the pressure is applied to the glass panel 10 by the pressure jig, and at this time, the extension 52 is pressed by the glass panel 10 to deform, and the glass panel 10 approaches and abuts against the support bar 30, so that the bonding member 40 can sufficiently bond the glass panel 10 and the support bar 30 firmly. In some embodiments, as shown in fig. 3 and 5, the supporting bar 30 is provided with a receiving groove 31 concavely formed in a direction away from the protruding portion 211, and the receiving groove 31 is used for receiving the connecting portion 51, so that the thickness of the screen assembly 100 in the first direction Z can be reduced compared to a manner in which the supporting bar 30 directly presses against the connecting portion 51. It can be appreciated that the connection manner between the connection portion 51 and the support bar 30 may be various, and may be a bonding manner such as glue or double sided tape; the connection may be made by a connecting member such as a bolt, and may be selected as needed. Illustratively, threaded holes (not shown) are formed in the support bar 30, and avoidance holes (not shown) are formed in the connecting portion 51 and the protruding portion 211, so that the connecting member is connected to the threaded holes in the support bar 30 after passing through the avoidance holes of the connecting portion 51 and the protruding portion 211. In this embodiment, an end surface of the connection portion 51 facing away from the protrusion portion 211 is provided with an adhesive layer (not shown), and the connection portion 51 is adhered to the support bar 30 by the adhesive layer. The bonding layer can be glue or double-sided adhesive, but can be other.

In some embodiments, as shown in fig. 5, the end of the support bar 30 facing away from the protrusion 211 is provided with a recess 32 and a flange 33 protruding relative to the recess 32, the recess 32 is provided with an adhesive 40, and the flange 33 abuts against the glass panel 10. The flange 33 reduces the contact area between the glass panel 10 and the support bar 30 and also constrains the adhesive 40 within the recess 32. In the present embodiment, the adhesive member 40 is glue. Of course, other adhesive structures, such as double sided tape, may be used for the adhesive 40. In addition, the adhesive member 40 may be a combination of various adhesive structures, for example, along the length direction of the frame strip 21, one end of the supporting strip 30 facing away from the protruding portion 211 is provided with glue and double-sided adhesive, and the double-sided adhesive is disposed between two adjacent sections of glue.

In some embodiments, the engagement of the extension 52 with the connection 51 is provided with a recess 53, the recess 53 being provided away from the protrusion 211, i.e. an end surface of the holder 50 facing away from the protrusion 211 is provided with the recess 53. It will be appreciated that the provision of the grooves 53 helps concentrate internal stresses of the brace 50 at the junction of the outer extension 52 and the connection 51, and helps the brace 50 break away from the junction of the outer extension 52 and the connection 51 when subjected to forces exceeding the limit that can be carried, reducing the risk of the brace 50 being subjected to excessive pressure and causing deformation of the brace bar 30. Meanwhile, due to the grooves 53, the extension 52 can be deformed relative to the connection portion 51 when the extension 52 is pressed by the glass panel 10.

It should be appreciated that the hardness of the stand 50 is less than the hardness of the ink at the edges of the glass panel 10 to reduce damage to the ink at the edges of the glass panel 10 from abutment by the stand 50, and also to facilitate reducing the risk of ink being scraped by the extension 52 during assembly by movement of the glass panel 10 in the XY plane.

In some embodiments, as shown in fig. 4, the connection portion 51 and the extension portion 52 have an included angle β, where β is greater than 90 degrees and smaller than 180 degrees, so that deformation energy caused by the force applied by the glass panel 10 on the support 50 is concentrated to the joint between the connection portion 51 and the extension portion 52, and meanwhile, compared to the manner that the extension portion 52 and the connection portion 51 are perpendicular to each other, when the end of the extension portion 52 away from the connection portion 51 carries the glass panel 10, a larger moment arm can be provided to the extension portion 52, so that the glass panel 10 is carried on the support 50 and deformed due to a larger moment.

It can be understood that the screen assembly 100 further includes a capacitive Film (not shown) and a liquid crystal panel (not shown), the capacitive Film is disposed between the glass panel 10 and the liquid crystal panel, the capacitive Film has a Chip On Film (COF) board 60 for connection, the Chip On Film board 60 is a die-attach package form for fixing an integrated circuit On a flexible circuit board, and a flexible circuit board is used as a carrier for packaging chips, so that packaging and electrical connection of the chips are achieved, and good flexibility is achieved.

Along a second direction M, which is a direction perpendicular to both the first direction Z and the longitudinal direction of the frame bar 21, the projection of the recess 2111 at least partially overlaps the projection of the extension 52. In this way, the flip film board 60 is convenient to pass through the space between the concave portion 2111 and the extension portion 52 for connection, and meanwhile, the extension portion 52 can be used for blocking light emitted by the backlight module of the touch display device from leaking to the outside from the gap between the frame 20 and the glass panel 10, so that the risk of light leakage is reduced. The screen assembly 100 provided in the embodiment of the present application includes a glass panel 10, a frame 20, a support bar 30, an adhesive member 40, and a bracket 50, where the frame 20 includes a plurality of connected frame bars 21, and the frame bars 21 include a protrusion 211 for carrying the glass panel 10; the support bar 30 is mounted to the protrusion 211; the bonding element 40 is arranged at one end of the supporting strip 30, which is away from the protruding part 211, and the bonding element 40 bonds the glass panel 10 and the supporting strip 30, and the direction of the bonding element 40 towards the glass panel 10 is defined as a first direction Z; the bracket 50 comprises a connecting part 51 connected with the outer extending part 52, the connecting part 51 is connected with the supporting bar 30, and the outer extending part 52 is positioned outside the protruding part 211 and is pressed by the glass panel 10 to deform; wherein the outer extension 52 is configured such that when the glass panel 10 is separated from the support bar 30, the outer extension 52 resumes deformation, and the dimension of the outer extension 52 in the first direction Z is greater than the dimension of the support bar 30 in the first direction Z, the outer extension 52 can abut the glass panel 10 such that the edge of the glass panel 10 has a gap with the support bar 30 in the first direction Z. In this way, in the assembly process, because the gap exists between the outer extension 52 and the support bar 30 under the abutment of the glass panel 10, the risk that the ink coated on the edge of the glass panel 10 is scraped by the support bar 30 in the process of moving the glass panel 10 is reduced, and the subsequent normal use of the screen assembly 100 is ensured.
