The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
The display panel 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
The display panel 100 according to the first embodiment of the present invention includes a panel main body portion 1, a bent portion 2, and a panel connecting portion 3. The panel main body 1 is provided with a display area, and the panel connecting portion 3 may be used to connect a circuit board 5 (e.g., a flexible circuit board 5).
Specifically, referring to fig. 1, one end of the bent portion 2 in the first direction may be connected to the panel main body portion 1, and the first direction may be a longitudinal direction or a width direction of the bent portion 2. For example, the first direction may be up and down in fig. 1. That is, one end of the bent portion 2 in the longitudinal direction is connected to the panel main body 1, or one end of the bent portion 2 in the width direction is connected to the panel main body 1.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
The panel connecting portion 3 is connected to the other end of the bent portion 2 in the first direction. As shown in fig. 1, the panel connection portion 3 and the display panel 100 are respectively located at two ends of the bending portion 2 in the first direction. At least one side edge of the panel connecting portion 3 in the second direction is collinear with an edge of the folded portion 2 in the second direction, which is perpendicular to the first direction. For example, the second direction may be a left-right direction in fig. 1.
Specifically, one side edge of the panel connecting portion 3 in the second direction is collinear with the edge of the bent portion 2 in the second direction, or both side edges of the panel connecting portion 3 in the second direction are collinear with the edges of the bent portion 2 in the second direction.
For example, in some embodiments of the present invention, the left side edge of the panel connecting portion 3 is collinear with the left side edge of the fold portion 2, and the right side edge of the panel connecting portion 3 is not collinear with the right side edge of the fold portion 2. As another example, in other embodiments of the present invention, the right side edge of the panel connecting portion 3 is collinear with the right side edge of the fold portion 2, and the left side edge of the panel connecting portion 3 is not collinear with the left side edge of the fold portion 2. For another example, in still other embodiments of the present invention, a left side edge of the panel connecting portion 3 is collinear with a left side edge of the folded portion 2, and a right side edge of the panel connecting portion 3 is collinear with a right side edge of the folded portion 2.
Like this, can reduce one or two chamfers between kink 2 and the panel connecting portion 3, reduce the chamfer quantity on display panel 100, improve display panel 100's structural strength, greatly reduced the cracked risk of kink 2.
For example, in the example of fig. 1, since both side edges of the panel connecting portion 3 in the second direction are collinear with the edges of the bent portion 2 in the second direction, there is no need to provide a chamfer between the bent portion 2 and the panel connecting portion 3, two chamfers can be reduced, the number of chamfers is changed from four to two, the structural strength of the display panel 100 is improved, and the risk of breaking the bent portion 2 is greatly reduced.
In the related art, in order to facilitate bending and connection of the circuit board 5, the panel main body portion 1 of the display panel 100 having the display area and the panel connecting portion 3 for connection with the circuit board 5 are generally designed to be wider, and the bent portion 2 is designed to be narrower. The inventor found that, in the related art, chamfers are generated between the bent portion 2 and the panel main body portion 1 and between the bent portion 2 and the panel connecting portion 3. The risk of breaking of the bend 2 is increased due to stress concentrations at the location of the chamfer.
According to the display panel 100 of the embodiment of the invention, at least one side edge of the panel connecting portion 3 in the second direction is set to be collinear with the edge of the bent portion 2 in the second direction, so that one or two chamfers between the bent portion 2 and the panel connecting portion 3 can be reduced, the number of chamfers on the display panel 100 is reduced, the structural strength of the display panel 100 is improved, and the risk of fracture of the bent portion 2 is greatly reduced.
According to some embodiments of the invention, at least one side edge of the panel connecting portion 3 in the second direction is perpendicular to the second direction. Specifically, one side edge of the panel connecting portion 3 in the second direction is perpendicular to the second direction, or both side edges of the panel connecting portion 3 in the second direction are perpendicular to the second direction.
For example, in the example of fig. 1 and 2, both side edges of the panel connecting portion 3 in the second direction are perpendicular to the second direction. At this time, both side edges of the panel connecting portion 3 extend in the vertical direction shown in fig. 1. The panel connecting portion 3 may be formed in a rectangular shape. The bent portion 2 may be formed in a rectangular shape or a square shape. The width of the bent portion 2 is equal to the width of the panel connecting portion 3. Thereby, the stress at the connection of the fold 2 and the panel can be further reduced, further reducing the risk of breakage of the fold 2.
It is understood that, in other embodiments of the present invention, when one side edge of the panel connecting portion 3 in the second direction is perpendicular to the second direction, the panel connecting portion 3 and the bent portion 2 may be formed in a right trapezoid shape. At this time, in the top-to-bottom direction, one side edge of the panel connection portion 3, which is not perpendicular to the second direction, may extend toward a direction away from one side edge of the panel connection portion 3, which is perpendicular to the second direction. Thereby, the bending of the bent portion 2 is facilitated, and the connection between the panel connecting portion 3 and the circuit board 5 is facilitated.
When both side edges of the panel connecting portion 3 in the second direction are not perpendicular to the second direction, the panel connecting portion 3 and the bent portion 2 may be formed in a trapezoidal shape. At this time, both side edges of the panel connecting portion 3 extend in a direction away from each other in the top-to-bottom direction. Thereby, the bending of the bent portion 2 is facilitated, and the connection between the panel connecting portion 3 and the circuit board 5 is facilitated.
According to some embodiments of the present invention, the panel connection part 3 is formed in a rectangular shape, and a length direction of the panel connection part 3 is the same as the first direction. As shown in fig. 1 and 2, the panel connecting portion 3 extends in the vertical direction in the longitudinal direction, and the bent portion 2 is formed in a rectangular shape or a square shape. From this, on the one hand can reduce the width of kink 2, the display panel 100 of being convenient for is buckled, and on the other hand, can increase the length dimension of panel connecting portion 3, can connect circuit board 5 on display panel 100's long edge, is favorable to increasing the area of contact between circuit board 5 and the panel connecting portion 3 to be convenient for connect circuit board 5 on panel connecting portion 3, and can improve the connection reliability between circuit board 5 and the panel connecting portion 3.
