[0011] In the display device provided by the present application, the spacer 40 is disposed between two adjacent flexible printed circuits 20, and the spacer 40 is at least partially located between the display panel 10 and the front frame 30, so that a certain buffer space is formed between the flexible printed circuit 20 and the front frame 30 to avoid indentations and damage caused by an external force on the flexible printed circuit 20, thereby effectively improving the product quality.

[0012] As shown in FIG. 3, among only some a plurality of flexible printed circuits 20 arranged at intervals, the spacer 40 is disposed between two adjacent flexible printed circuits 20, thereby reducing process steps while ensuring that the certain buffer space is formed between the flexible printed circuit 20 and the front frame 30.

[0013] In the embodiments of the present application, the spacer 40 is disposed on a side surface of the display panel 10 facing the front frame 30. Specifically, the spacer 40 is disposed on a side surface of the first substrate 101 on a side where the bonding region BA is disposed. The spacer 40 is provided to apply an outward force to the front frame 30 locked inward, so that the certain buffer space is formed between the flexible printed circuit 20 and the front frame 30, so as to avoid indentations and damage caused by an external force on the flexible printed circuit 20, thereby effectively improving the product quality.

[0014] In the embodiments of the present application, an adhesive layer may be disposed between the spacer 40 and a side surface of the first substrate 101 facing the front frame 30. The spacer 40 is fixed on the side surface of the first substrate 101 facing the front frame 30 through the adhesive layer. On one hand, the spacer 40 can be positioned through adhesiveness of the adhesive layer, and on the other hand, a support strength of the spacer 40 for the front frame 30 can be further improved. The adhesive layer may be a double-sided adhesive.

One spacer 40 is disposed between two adjacent flexible printed circuits 20 to improve the support performance of the spacer, so as to ensure that the certain buffer space is formed between the flexible printed circuit 20 and the front frame 30, thereby preventing the flexible printed circuits 20 from being damaged by an external force.

[0023] In the embodiments of the present application, an adhesive layer may be disposed between the spacer 40 and the front frame 30. The adhesive layer fixes the spacer 40 on the side surface of the front frame 30 facing the display panel 10.

Specifically, the backplane 51 includes a main body portion and a plurality of enclosure plate portions disposed on a periphery of the main body portion. The plurality of enclosure plate portions are all fixedly connected to the main body portion. For example, the main body portion and the plurality of enclosure plate portions are of an integrally formed structure. The main body portion and the plurality of enclosure plate portions form an accommodating groove. Other components of the backlight module 50, such as the diffusion plate 53 and the backlight source 54, can be accommodated in the accommodating groove. The diffusion plate 53 is disposed in the accommodating groove. The diffusion plate 53 may include a plurality of side portions.

An orthographic projection of the first frame portion 31 covers the orthographic projection of the bonding region BA. The second frame portion 32 covers the flexible printed circuit 20, the middle frame 57, and the enclosure plate portions of the backplane 51.

[0035] In the embodiments of the present application, the middle frame 57 is disposed between the backplane 51 and the front frame 30, and is configured to provide support for the diffusion plate 53. Another end of the flexible printed circuit 20 is located between the front frame 30 and the middle frame 57. The middle frame 57 is provided with the second screw hole. The second screw hole is provided corresponding to the first screw hole 33. The fixing member 58 is disposed in the first screw hole 33 and the second screw hole. The front frame 30 is connected to the middle frame 57 through the fixing member 58. Specifically, the fixing member 58 may be a screw. The screw is inserted into the first screw hole 33 and the second screw hole, so that the front frame 30 is fixedly connected the middle frame 57.

[0036] As shown in FIG. 9, the second frame portion 32 of the front frame 30 is provided with the first screw hole 33. The first screw hole 33 is located between two adjacent flexible printed circuits 20 and located on a side of the spacer 40 away from the light-emitting surface of the display panel.

[0037] As shown in FIG. 10, the front frame 30 is further provided with an opening 34. The opening 34 is provided on a side of the first screw hole 33 close to the light-emitting surface of the display panel. That is, the opening 34 is provided above the first screw hole 33. When the screw is locked with the first screw hole 33, a locking force from the front frame 30 to the display panel is generated. The opening 34 is provided above the first screw hole 33, so as to prevent the locking force generated when the screw is locked with the first screw hole 33 from being uploaded to a position corresponding to the flexible printed circuit 20 on the upper side of the front frame 30, thereby reducing an external pressure on the flexible printed circuit 20, avoiding a problem of abnormal display images caused by indentation or damage of the flexible printed circuit 20 under the direct or indirect external pressure, and effectively improving the product quality.

[0038] In the embodiments of the present application, the opening 34 includes a linear elongated hole. That is, a shape of the opening 34 may be a long strip. A cross-sectional width of the opening 34 in the horizontal direction is greater than or equal to a diameter of the first screw hole 33. Specifically, the horizontal direction may be the width direction of the display panel or the length direction of the display panel. Preferably, the cross-sectional width of the opening 34 along the direction from the flexible printed circuit 20 to the spacer 40 on the same side is greater than the diameter of the first screw hole 33, so as to more effectively reduce the influence of the locking force on the flexible printed circuit 20.

[0039] As shown in FIG. 11, the shape of the opening 34 includes an arc-shaped hole in a form of an arc line. In order to ensure the stability of the front frame 30 and prevent the locking force generated when the screw is locked with the first screw hole 33 from being uploaded to the flexible printed circuit, and the flexible printed circuit is prevented from being damaged by an external force. Preferably, an angle of the arc-shaped opening 34 ranges from 90 degrees to 180 degrees. The angle of the arc-shaped opening 34 includes 90 degrees, 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 160 degrees, 170 degrees, and 180 degrees.

[0040] As shown in FIG. 12, the opening 34 includes a first sub-opening 341 and a second sub-opening 341. An end portion of the first sub-opening 341 is cross-communicated with and end portion of the second sub-opening 342. An included angle between the first sub-opening 341 and the second sub-opening 342 ranges from 60 degrees to 150 degrees. The included angle of the opening 34 includes 60 degrees, 70 degrees, 80 degrees, 90 degrees, 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, and 150 degrees. The opening 34 is provided in a "V" shape, which is conducive to prevent the locking force generated when the screw is locked with the first screw hole 33 from being uploaded to two adjacent flexible printed circuits above the first screw hole 33, thereby preventing the two adjacent flexible printed circuits above the first screw hole 33 from being damaged by external forces.

[0041] In the embodiments of the present application, a length of the opening 34 is negatively correlated with the included angle between the first sub-opening 341 and the second sub-opening 342. That is, the larger the included angle of the opening 34, the smaller the length of the opening 34. For example, the length of the opening 34 with an included angle of 60 degrees is greater than the length of the opening 34 with an included angle of 120 degrees. The length of the opening 34 is negatively correlated with the included angle between the first sub-opening 341 and the second sub-opening 342, so that the locking force when the screw is screwed with the first screw hole 33 can be better released, thereby preventing the two adjacent flexible printed circuits 20 above the first screw hole 33 from being damaged by the external force.

[0042] The present application provides a display device. The display device includes a display panel 10, at least one flexible printed circuit 20, a front frame 30, and at least one spacer 40. The display panel 10 includes a display region AA and a bonding region BA. The bonding region BA is located on at least one side of the display region AA.
