Figure 2 This is a schematic diagram of the structure of a display module provided in an embodiment of this application from another perspective. Figure 2 for Figure 1 A structural diagram from the left-hand perspective.

[0040] like Figure 1 and Figure 2 As shown, an embodiment of the first aspect of this application provides a display module, which includes a display screen body 100, a first circuit board 200, and a second circuit board 300. The display screen body 100 includes a display area AA and a bonding area BA located on one side of the display area AA in a first direction X. The first circuit board 200 includes a first body 210 and a first pin 220. A first bonding area 211 is disposed on the first body 210. The first pin 220 is connected to at least one side of the first bonding area 211 in a second direction Y. A second bonding area 221 is disposed on the first pin 220 and bonded to the bonding area BA through the second bonding area 221. The first pin 220 is bent so that the first bonding area 211 and the second bonding area 221 at least partially overlap along the first direction X. The second circuit board 300 is bonded between the bonding area BA and the first bonding area 211. The first direction Z and the second direction Y intersect.

[0041] Figure 1 The positions of the first binding area 211 and the second binding area 221 are indicated by dashed boxes. The dashed lines do not constitute a limitation on the display module structure provided in the embodiments of this application.

[0042] Optional, such as Figure 1 As shown, the display body 100 also includes a non-display area NA, and the bonding area BA is located within the non-display area NA.

[0043] In the display module provided in this application embodiment, the display module includes a display screen body 100 and a first circuit board 200 and a second circuit board 300 bonded to the display screen body 100. The first circuit board 200 includes a first body 210 and a first pin 220. A first bonding area 211 is provided on the first body 210, so that the second circuit board 300 can be bonded between the bonding area 211 and the first bonding area 211. The first pin 220 is located on one side of the first bonding area 211 of the first body 210, and the first pin 220 is bent so that the first bonding area 211 and the second bonding area 221 at least partially overlap along the first direction X. As a result, the area in the bonding area 210 for bonding the second circuit board 300 and the area for bonding the first pin 220 at least partially overlap in the first direction X, which can reduce the extension length of the bonding area 211 in the second direction X, thereby reducing the distribution area of ​​the non-display area NA on the display screen body 100 and improving the display effect of the display module.

[0044] The bending configuration of the first pin 220 to at least partially overlap the first bonding area 211 and the second bonding area 221 along the first direction X means that: the first pin 220 extends along the bending path, and the end of the first pin 220 away from the first body 210 bends toward the second bonding area 221, that is, the end of the first pin 220 connected to the bonding area BA is located on one side of at least part of the second bonding area 221 in the first direction X, such that the projection of the first bonding area 211 in the first direction X and the projection of the second bonding area 221 in the first direction X at least partially overlap, and the sum of the extension dimension of the first bonding area 211 in the first direction X and the extension dimension of the second bonding area 221 in the first direction X is greater than the extension dimension of the bonding area BA in the first direction X.

[0045] Optionally, the bonding area BA is provided with multiple bonding pins, and the second bonding area 221 of the first pin 220 and the second circuit board 300 are both provided with multiple bonding pins. The first pin 220 and the second circuit board 300 are both bonded to the bonding area BA through bonding pins. Optionally, the first bonding area 211 is provided with multiple bonding pins, and the second circuit board 300 is bonded to the first bonding area 211 through bonding pins.

[0046] Optional, such as Figure 2 As shown, the bonding area BA is provided with a first bonding part 111 and a second bonding part 131. The first bonding part 111 is bonded to the second circuit board 300, and the second bonding part 131 is bonded to the second bonding area 221 of the first pin 220. Optionally, both the first bonding part 111 and the second bonding part 131 include a plurality of bonding pins arranged side by side along the second direction Y. The first bonding part 111 is bonded to the second circuit board 300 by the plurality of bonding pins, and the second bonding part 131 is bonded to the first pin 220 by the plurality of bonding pins.

[0047] Optionally, the second circuit board 300 extends along the first direction X and is connected between the first bonding portion 111 and the first bonding area 211 of the first body 210. Optionally, at least a portion of the first pin 220 is located on one side of at least a portion of the second circuit board 300 in the second direction Y. In the direction from the first body 210 to the display screen body 100, the first pin 220 is bent from one side of the second circuit board 300 to at least partially overlap with the second circuit board 300 along the thickness direction of the display module, such that the second bonding area 221 and the first bonding area 211 at least partially overlap along the first direction X, and the second bonding portion 131 and the first bonding portion 111 at least partially overlap along the first direction X.

[0048] Optionally, the first circuit board 200 is connected to the touch circuit of the display screen via the first pin 220 for transmitting touch signals. The second circuit board 200 is connected to the light-emitting driving circuit of the display screen for transmitting light-emitting driving signals.

[0049] There are multiple ways to configure the display screen 100; please refer to the following documentation. Figure 1 and Figure 2 The display screen body 100 includes an array substrate 110, a light-emitting layer 120, and a functional layer 130 stacked sequentially along its thickness direction. Optionally, the display screen body 100 also includes a substrate located on the side of the array substrate 110 opposite to the light-emitting layer 120. Optionally, the array substrate 110 includes a light-emitting driving circuit, and the light-emitting layer 120 includes light-emitting units, the light-emitting driving circuit being used to drive the light-emitting units to emit light. Optionally, the functional layer 130 includes a cover plate and a touch circuit layer, the touch circuit layer including touch circuitry and used to implement the touch function of the display module.

[0050] In some optional embodiments, the first bonding portion 111 is disposed on the array substrate 110 and located in the bonding area BA, and the second bonding portion 131 is disposed on the functional layer 130 and located in the bonding area BA. In these optional embodiments, the first bonding portion 111 and the second bonding portion 131 are staggered, which can further reduce the overall distribution area of ​​the bonding area BA, increase the distribution ratio of the display area AA of the display screen body 100, and thus improve the display effect of the display module.

[0051] Optionally, the first bonding part 111 is connected to the light-emitting driving circuit, and the second circuit board 300 is used to connect to the display driver 340, so that the display driver 340 can transmit control signals to the light-emitting driving circuit through the second circuit board 300 and the first bonding part 111. Optionally, the first circuit board 200 is used to connect to the touch driver 230, and the second bonding part 131 is connected to the touch circuit, so that the touch driver 230 can transmit control signals to the touch circuit through the first circuit board 200 and the second bonding part 131.

[0052] Optionally, the second circuit board 300 is provided with binding pins on both sides opposite to each other along its thickness direction, so that the second circuit board 300 is connected between the first binding part 111 and the first binding area 211 by the binding pins located on both sides opposite to each other in its thickness direction.

[0053] In some alternative embodiments, the second circuit board 300 includes a first connecting portion 310 and a second connecting portion 320. The first connecting portion 310 is interconnected with the first bonding portion 111 and is located on the side of the array substrate 110 facing the light-emitting layer 120, and the first connecting portion 310 is located on the side of the first body 210 facing the array substrate 110. The second connecting portion 320 is connected to the side of the first connecting portion 310 away from the display screen body 100, and the second connecting portion 320 is located on the side of the first body 210 facing the light-emitting surface of the display module and is interconnected with the first bonding area 211.

[0054] In these optional embodiments, the first connection portion 310 of the second circuit board 300 is located on the side of the array substrate 110 facing the light-emitting layer 120, that is, the first connection portion 310 is located on the side of the array substrate 110 facing the light-emitting surface of the display module. The second connection portion 320 of the second circuit board 300 is also located on the side of the first body 210 facing the light-emitting surface of the display module. Therefore, the first bonding portion 111 and the first bonding area 211 can be connected using a second circuit board 300 with bonding pins on only one side. That is, bonding pins can be provided on one surface of the second circuit board 300, which simplifies the structure of the second circuit board 300.

[0055] In some optional embodiments, the second circuit board 300 further includes a second body 330 connected between the first connecting portion 310 and the second connecting portion 320; two first pins 220 are respectively disposed on both sides of the second body 330 in the second direction Y, and the maximum distance between the two first pins 220 is greater than or equal to the width of the second connecting portion 320 in the second direction Y.

[0056] In these optional embodiments, the distance between the two first pins 220 located on both sides of the second body 330 is relatively large. During the assembly process of the display module, it is convenient to bend the second connecting part 320 from the lower side of the first circuit board 200 (i.e. the side away from the light-emitting surface of the display module) between the two first pins 220 to the upper side of the first circuit board 200 (i.e. the side facing the light-emitting surface of the display module), which can simplify the assembly process of the display module and improve the assembly efficiency of the display module.

[0057] In some alternative embodiments, the extension length of the first connecting portion 310 and / or the second connecting portion 320 in the second direction Y is less than or equal to the extension length of the second body 330 in the second direction Y.

[0058] In these alternative embodiments, the second body 330 has a larger extension length in the second direction Y, while the first connecting portion 310 and / or the second connecting portion 320 have a smaller extension length in the second direction Y. This allows the extension length of the first bonding portion 111 connected to the first connecting portion 310 in the second direction Y to be designed to be smaller, reducing the distribution area of ​​the non-display area NA on the display screen body 100 and improving the display effect. Alternatively, the extension length of the first bonding area 211 connected to the second connecting portion 320 in the second direction Y can be designed to be smaller, reducing the size of the second circuit board 300 and improving the structure of the display module. In addition, the larger size of the second body 330 makes it less likely for the first connecting portion 310 and / or the second connecting portion 320 to be bumped during transportation.

[0059] This application also provides an assembly method for a display module, wherein the display module is any of the display modules described in the first aspect of the above-described embodiment, and the assembly method includes:

[0060] Step 1: Provide the above-mentioned display screen body 100, which includes a display area AA and a binding area BA located on at least one side of the display area AA.

[0061] Step two, the first circuit board 200 is bonded to the bonding area BA. As described above, the first circuit board 200 includes a first body 210 and a first pin 220. The first pin 220 is connected to at least one side of the first bonding area 211 in the second direction Y. A second bonding area 221 is provided on the first pin 220 and it is bonded to the bonding area BA through the second bonding area 221. The first pin 220 is bent so that the first bonding area 211 and the second bonding area 221 at least partially overlap in the first direction X.

[0062] Step 3: The first connecting portion 310 of the second circuit board 300 is bonded to the bonding area BA from the side of the first circuit board 200 away from the light-emitting surface of the display module. For example, the first connecting portion 310 is bonded to the first bonding portion 111. At this time, at least a portion of the first connecting portion 310 and at least a portion of the first pin 220 are overlapped along the thickness direction.

[0063] Step four, at least a portion of the second circuit board 300 is bent from the first pin 220 on one side of the second direction Y to the side of the first circuit board 200 facing the light-emitting surface of the display module, and the second connection portion 320 of the second circuit board 300 is bound to the first binding area 211.

[0064] Alternatively, in some alternative embodiments, in step two, the second circuit board 300 can be first bonded between the bonding area BA and the first bonding area 211 of the first circuit board 200. For example, the first connecting portion 310 of the second circuit board 300 can be bonded to the first bonding portion 111 of the array substrate 110, and the second connecting portion 320 of the second circuit board 300 can be bonded to the side of the first body 210 facing the light-emitting surface of the display module. Then, in step three, the first pin 220 is bent and bonded to the bonding area BA. For example, the first pin 220 can be bonded to the second bonding portion 131, and the first pin 220 overlaps with at least a portion of the second circuit board 300 in the thickness direction.

[0065] In any of the above embodiments, the relative positions of the first binding part 111 and the second binding part 131 can be arranged in various ways. For example, the projections of the first binding part 111 and the second binding part 131 along the first direction X can completely overlap, that is, the lengths of the first binding part 111 and the second binding part 131 in the second direction Y are equal, and the first binding part 111 and the second binding part 131 are aligned along the first direction X. This can further reduce the size of the binding area BA in the second direction Y, making it easier to arrange the first binding part 111 and the second binding part 131 containing more pins within the same length. It can also increase the screen ratio of the display area AA and improve the display effect of the display module.

[0066] In some alternative embodiments, for example, the extension length of the first binding portion 111 in the second direction Y is greater than the extension length of the second binding portion 131 in the second direction Y, and the orthographic projection of the second binding portion 131 in the first direction X is located within the orthographic projection of the first binding portion 111 in the first direction X. In these alternative embodiments, the length of the first binding portion 111 is greater than the length of the second binding portion 131, so the projection of the second binding portion 131 is located within the first binding portion 111, the second binding portion 131 does not occupy additional length, and the length of the first binding portion 111 is the length of the entire binding area BA, which can reduce the length of the binding area BA.

[0067] In some other embodiments, the extension length of the second binding portion 131 in the second direction Y is greater than the extension length of the first binding portion 111 in the second direction Y, and the orthographic projection of the first binding portion 111 in the first direction X is located within the orthographic projection of the second binding portion 131 in the first direction X. In these optional embodiments, the length of the second binding portion 131 is greater than the length of the first binding portion 111, so the projection of the first binding portion 111 is located within the second binding portion 131, the first binding portion 111 does not occupy additional length, and the length of the second binding portion 131 is the length of the entire binding area BA, which can reduce the length of the binding area BA.

[0068] There are several ways to set the number of pins 220, such as Figure 3 As shown, the first pin 220 has a connection terminal for connecting to the first body 210. There can be only one first pin 220. The connection terminal of one first pin 220 is located on one side of the second circuit board 300 in the second direction Y. For example, one first pin 220 is located on one side of the second body 330 in the second direction Y. Or, as... Figure 1 As shown above, there are two first pins 220. The connection ends of the two first pins 220 are distributed on both sides of the second circuit board 300 in the second direction Y. For example, the two first pins 220 are respectively located on both sides of the second body 330 in the second direction Y.

[0069] Optionally, as described above, the second circuit board 300 is connected to a display driver 340, and the first circuit board 200 is connected to a touch driver 230. The touch driver 230 can be disposed on the first circuit board 200, which may further include a first circuit and a second circuit. The display driver 340 is interconnected with the first circuit through a first bonding area 211, thereby enabling the display driver 340 to be interconnected with an external controller through the first circuit. The touch driver 230 is interconnected with the second circuit, thereby enabling the touch driver 230 to be interconnected with an external controller through the second circuit.

[0070] In this embodiment, both the display driver 340 and the touch driver 230 are electrically connected to the outside via circuits on the second circuit board 300. The second circuit board 300 does not need to be bonded to the outside again, which simplifies the structure of the display module and improves the manufacturing efficiency of the display module.

[0071] Optionally, a touch circuit is provided in the functional layer 130. The touch driver 230 is interconnected with the touch circuit of the display body 100 through the first pin 220 and the second bonding area 221, so that the touch driver 230 can transmit control signals to the touch circuit.

[0072] There are multiple ways to set the shape of the first pin 220, as long as the first pin 220 is bent so that the first binding area 211 and the second binding area 221 at least partially overlap along the first direction X.

[0073] In some alternative embodiments, the first pin 220 includes an extension 222 and a bend 223. The extension 222 is connected to at least one side of the first bonding area 211 in the second direction Y and extends along the first direction X; the bend 223 is connected to the side of the extension 222 away from the first body 210, and in the direction from the first circuit board 200 to the display body 100, the bend 223 is bent in a direction close to the first bonding area 211.

[0074] In these alternative embodiments, the first pin 220 includes an extension 222 and a bend 223. The extension 222 connects to the first body 210 and is located on at least one side of the first bonding region 211 in the second direction Y. For example, the extension 222 may be located on at least one side of the second connection portion 320 and the second body 330 in the second direction Y. The extension 222 extending along the first direction X simplifies the structure of the first pin 220. The bend 223 bends along a direction close to the first bonding region 211, such that the first bonding region 211 and the second bonding region 221 can at least partially overlap along the first direction X.
