[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0025] A double-sided display module, referring to Figure 1 , including a display module body 10, the display module body 10 includes two display screens, both of which are TFT display screens, and the two display screens are arranged to be opposite to each other. The two display screens are respectively located on two sides of the display module body 10 that are opposite to each other, so that images can be displayed on both sides of the display module body 10.

[0026] Reference Figure 2 , the two display screens are respectively a first display screen 20 and a second display screen 30, and the display areas of the first display screen 20 and the second display screen 30 are arranged opposite to each other. The first display screen 20 includes a first upper polarizer 21, a first upper glass 22, a first lower glass 23, and a first lower polarizer 24 arranged from left to right. The second display screen 30 includes a second upper polarizer 31, a second upper glass 32, a second lower glass 33, and a second lower polarizer 34 arranged from right to left, and the first lower polarizer 24 and the second lower polarizer 34 are arranged adjacent to each other.

[0027] Reference Figure 2The lower end length of the first lower glass 23 is longer than the lower end length of the first upper glass 22. The first lower glass 23 is bound to the first upper glass 22 on one side thereof. One end of the first FPC 25 is bound to the first lower glass 23 beyond the first upper glass 22. The other end of the first FPC 25 is used to connect to the customer's mainboard to ensure the normal use of the first display screen 20. The lower end length of the second lower glass 33 is longer than the lower end length of the second upper glass 32. The second lower glass 33 is bound to the second FPC 35 on one side thereof toward the second upper glass 32. One end of the second FPC 35 is bound to the second lower glass 33 beyond the second upper glass 32. The other end of the second FPC 35 is used to connect to the customer's mainboard to ensure the normal use of the second display screen 30. The first FPC 25 and the second FPC 35 are both arranged vertically, and the first FPC 25 and the second FPC 35 are arranged in parallel. By arranging the first display screen 20 and the second display screen 30 away from each other, images can be displayed on both sides of the display module body 10, so that both sides can be displayed simultaneously for publicity and other operations.

[0028] Reference Figure 2 and Figure 3 The display module body 10 also includes a backlight module, which includes a backlight iron frame 40 and two backlight plastic frames 50. The backlight module is disposed between the first display screen 20 and the second display screen 30, and the backlight module wraps the first display screen 20 and the second display screen 30 respectively.

[0029] Reference Figure 2 and Figure 3 The backlight iron frame 40 is arranged in an I-shape, the middle part of the backlight iron frame 40 is an iron frame bottom plate 41, and two mutually opposite sides of the backlight iron frame 40 are provided with accommodating grooves 42, and the two accommodating grooves 42 are respectively provided on the two sides of the backlight iron frame 40 relative to the iron frame bottom plate 41, and the two accommodating grooves 42 of the backlight iron frame 40 are respectively provided to accommodate the first display screen 20 and the second display screen 30. The first display screen 20 and the second display screen 30 are respectively accommodated in the two accommodating grooves 42 of the backlight iron frame 40, and the first display screen 20 and the second display screen 30 are respectively connected to the two sides of the iron frame bottom plate 41.

[0030] Reference Figure 2 and Figure 3The backlight iron frame 40 wraps the sides of the first display screen 20 and the second display screen 30 to prevent the first display screen 20 and the second display screen 30 from shaking and being damaged. By setting an I-shaped backlight iron frame 40 to connect the two display screens, the first display screen 20 and the second display screen 30 share the iron frame bottom plate 41, which saves materials and makes the display module body 10 of the double-sided screen thinner, more compact and stable. The two backlight glue frames 50 are respectively arranged opposite to the two sides of the backlight iron frame 40 that are separated from each other, and the two backlight glue frames 50 are respectively arranged along the inner circumferential direction of the two sides of the backlight iron frame 40.

[0031] Further, refer to Figure 2 and Figure 3 The first display screen 20 and the second display screen 30 are respectively provided with a backlight for providing brightness on one side close to the iron frame bottom plate 41. The backlight is a part of the backlight module, which is used to provide light source for the first display screen 20 and the second display screen 30 so that the first display screen 20 and the second display screen 30 display the picture.
