DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0029] In the description of this application, it should be understood that the words "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] At the same time, the present application uses specific words to describe the embodiments of the present application. For example, "one embodiment", "an embodiment", and / or "some embodiments" refer to a certain feature, structure or characteristic related to at least one embodiment of the present application. Therefore, it should be emphasized and noted that "one embodiment" or "an embodiment" or "an alternative embodiment" mentioned twice or more in different positions in this specification does not necessarily refer to the same embodiment. In addition, some features, structures or characteristics in one or more embodiments of the present application can be appropriately combined.

[0031] See also Figures 1 to 3 , an embodiment of the present application provides a display module, including a display panel 100 and a flexible circuit board 300. The display panel further includes a panel portion 110, a terminal portion 200 and a bending portion 112. The display panel 100 is rectangular, having a length direction Y and a width direction X. One side of the panel portion 110 in the length direction Y is connected to the terminal portion 200 through the bending portion 112. Specifically, one side of the panel portion in the length direction has an edge 111, and the edge 111 is connected to the bending portion 112, and then the edge 111 is indirectly connected to the terminal portion 200. The terminal portion 200 is bent to the back of the panel portion 110. A pad is provided on the side of the terminal portion 200 away from the bending portion 112.

[0032] The flexible circuit board 300 is electrically connected to the terminal part 200 and is located on the back side of the display panel 100 , and at least a portion of the flexible circuit board 300 is located on one side of the terminal part 200 along the width direction X.

[0033] The technical solution provided in the present application arranges a part of the flexible circuit board 300 on one side of the terminal portion 200 along the width direction X of the display panel 100, so that a part of the flexible circuit board 300 and the terminal portion 200 are arranged side by side in the width direction X, and the area of ​​the display panel 100 already occupied by the terminal portion 200 in the length direction Y is fully utilized, so that the arrangement of the flexible circuit board 300 does not occupy too much area of ​​the back side of the display panel 100 in the length direction Y, thereby achieving the purpose of saving space. The excess area of ​​the back side of the display panel 100 in the length direction Y can be used to arrange more other components or arrange larger components, etc., which is conducive to the miniaturization of the display module. In detail, in the related art, after the flexible circuit board 300 is bent with the terminal part 200, the area occupied by the flexible circuit board 300 in the length direction Y will be further increased on the basis of the area occupied by the terminal part 200 in the length direction Y of the back of the display panel 100, resulting in the flexible circuit board 300 and the terminal part 200 jointly occupying a large area of ​​the back of the display panel 100 in the length direction Y, resulting in the reduction of the arrangement space of other components, and may also cause a large area of ​​the back of the display panel 100 in the width direction X. In the present application, by arranging a part of the flexible circuit board 300 on one side of the terminal part 200 along the width direction X, that is, a part of the flexible circuit board 300 and the terminal part 200 are arranged side by side in the width direction X, so as to make full use of the area of ​​the display panel 100 in the width direction X as much as possible, so as to save the space of the display panel 100 in the length direction Y. And because the terminal portion 200 has occupied part of the area of ​​the display panel 100 in the length direction Y, the flexible circuit board 300 is equivalent to reusing the size of the display panel 100 in the length direction Y occupied by the terminal portion 200, further making the arrangement between the flexible circuit board 300 and the terminal portion 200 more compact. Specifically, even if the size in the length direction Y occupied by the terminal portion 200 is not occupied, it is difficult to install more other components within the size in the length direction Y, that is, not occupying this part of the space will also cause waste of the area of ​​the display panel 100 in the width direction X, and the flexible circuit board 300 also needs to occupy more of the size of the display panel 100 in the length direction Y, resulting in more waste of area.

[0034] It should be noted that the panel portion 110 includes a display area and a peripheral area, the peripheral area surrounds the display area, the display area is mainly used to display images, and the peripheral area is mainly used for wiring. The edge 111 of the panel portion 110 in the length direction refers to the contour edge of the outer contour of the panel portion 110 in the length direction Y.

[0035] In some embodiments, along the width direction X, the center line of the terminal portion 200 is located on one side of the center line of the panel portion 110, that is, the terminal portion 200 is non-centrally arranged compared to the panel portion 110, providing space for the flexible circuit board 300 to be arranged on one side of the terminal portion 200 in the width direction X, thereby preventing the flexible circuit board 300 from exceeding the panel portion 110 by too much area in the width direction X. Specifically, the terminal portion 200 can be arranged on the left side of the panel portion 110 in the length direction Y, or on the right side of the panel portion 110 in the length direction Y, without limitation.

[0036] In some embodiments, along the width direction X, the width of the terminal portion 200 is smaller than the width of the panel portion 110, and a side edge of the terminal portion 200 in the width direction X and the edge 111 define an accommodation space. The edge 111 is manufactured by a precise laser cutting process, which ensures that the terminal portion 200 can be tightly connected to the flexible circuit board 300 after bending, and the panel portion 110 or the terminal portion 200 will not be damaged during the cutting process. A portion of the flexible circuit board 300 is electrically connected to the terminal portion 200 and is bent to the back of the display panel 100 together with the terminal portion 200, and another portion of the flexible circuit board 300 is located on the other side of the edge 111 and the terminal portion 200 along the width direction X. This accommodation space is specifically provided for the installation space of components (such as capacitors, resistors, etc.) on the flexible circuit board 300, ensuring that the components can be compactly and reasonably arranged in the display module.

[0037] In specific operation, the edge 111 is processed by laser cutting technology to form a clear boundary with the bending portion 112 and maintain a certain structural strength, so as not to affect the reliability of the entire module. When the terminal portion 200 is bent, the connection portion 310 and the device portion 330 of the flexible circuit board 300 are also arranged together, so that the entire module is optimally arranged within the limited back space, and the device portion 330 avoids direct overlap with the terminal portion 200.

[0038] In the traditional design, after the terminal part 200 is bent, the flexible circuit board 300 and the terminal part 200 occupy the back space in the length direction Y. If other components are to be arranged, it is necessary to expand the module in the length direction Y, which will directly increase the size of the module. The present invention places a part of the flexible circuit board 300 in the side area of ​​the terminal part 200 through the division of the edge 111 and the accommodation space, rather than directly in the length direction Y behind the terminal part 200, so that the back space of the display panel 100 is more efficiently utilized, avoiding the overlapping layout of the flexible circuit board 300 and the terminal part 200, and at the same time releasing more space for the arrangement of components. The division of the accommodation space not only saves space, but also enables the components (such as chips, resistors, etc.) on the flexible circuit board 300 to be reasonably distributed on the back of the display module. By reserving sufficient accommodation space by the edge 111, it can be ensured that these components will not cause physical or electrical interference with the terminal part 200, thereby improving the overall performance of the display module.

[0039] For further information, see Figure 1 and Figure 2 , the flexible circuit board 300 includes a connection part 310 and a device part 330. The connection part 310 is connected to one side of the terminal part 200 and is bent to the back of the display panel 100 together with the terminal part 200. The device part 330 is arranged side by side with the connection part 310 in the width direction X, and the device part 330 is mainly used to accommodate other components, such as driving chips, resistors, capacitors, etc. The device part 330 and the terminal part 200 are arranged side by side on the back of the panel part 110 in the width direction X, reducing the occupation of the module in the length direction Y. In addition, the edge 111 is formed by a precise cutting process during the production process of the display module, so that the display panel 100 reserves a layout space for the device part 330 in the width direction X. The device part 330 is located in the accommodation space defined by the edge 111, so that the device part 330 of the flexible circuit board 300 will not overlap with the terminal part 200, and can be compactly and reasonably arranged in the accommodation space.

[0040] In this embodiment, the device portion 330 of the flexible circuit board 300 and the terminal portion 200 are arranged side by side in the width direction X, and the device portion 330 of the flexible circuit board 300 and the connecting portion 310 are connected to each other, so that the space occupied by the device portion 330 of the flexible circuit board 300 and the space occupied by the terminal portion 200 are independent of each other and do not affect each other, so that the terminal portion 200 and the flexible circuit board 300 can be more closely combined together, thereby improving the overall compactness of the module.

[0041] In some embodiments, the flexible circuit board 300 further includes a board-to-board connector 350, which is connected to the side of the device portion 330 away from the edge 111 in the length direction Y. The board-to-board connector 350 enables the flexible circuit board 300 to be efficiently electrically connected to other circuit modules. By providing the board-to-board connector 350 at the end of the length direction Y of the flexible circuit board 300, the electrical signal can be transmitted from the flexible circuit board 300 to the main circuit board, avoiding the signal loss problem that may occur in the traditional way.

[0042] In some embodiments, please participate Figure 2 and Figure 3 The terminal part 200 includes a first contour 210 facing the flexible circuit board 300 along the width direction X, and the flexible circuit board 300 includes a second contour 320 facing the terminal part 200 along the width direction X. The shape of the first contour 210 is configured in a contoured manner with the shape of the second contour 320, and the first contour 210 and the second contour 320 are spaced apart, so that the device part 330 and the terminal part 200 can make full use of the area in the width direction X of the display panel 100 as much as possible, and can also ensure that the device part 330 and the terminal part 200 will not be in direct contact, avoiding circuit interference, short circuit and other problems. In addition, the terminal part 200 and the device part 330 are spaced apart, which can also ensure that when the module is laser cut, the structure of the flexible circuit board 300 will not be affected by the laser cutting and fail. It should be noted that the gap between the terminal portion 200 and the device portion 330 is mainly determined based on the cutting of the display panel 100. In detail, before the flexible circuit board 300 is bound to the terminal portion 200, the display panel 100 will be cut to form an edge 111. During the cutting, it will be precisely cut according to the size of the flexible circuit board 300 so that after the flexible circuit board 300 is subsequently bound to the terminal portion 200, a gap can be formed between the flexible circuit board 300 and the terminal portion 200 in the width direction X.

[0043] In some embodiments, the first contour 210 and the second contour 320 are both chamfered.

[0044] For further information, see Figure 4 The first profile 210 includes a vertical section 211 and an inclined section 212. The vertical section 211 is connected to the inclined section 212, and along the length direction Y, the inclined section 212 is inclined toward the bending portion 112, so that the vertical section 211 and the inclined section 212 constitute a chamfered structure of the terminal portion 200, and the chamfered structure is surrounded by the second profile 320 and the connecting portion 310.

[0045] The technical solution provided in this embodiment is composed of a vertical section 211 and an inclined section 212 by utilizing the first profile 210, the vertical section 211 is connected to the bending section 112 of the display panel 100, the inclined section 212 is connected to the vertical section 211 and extends to the back of the display panel 100, and the end of the inclined section 212 away from the vertical section 211 is connected to the side of the terminal part 200 away from the bending section 112, forming a chamfered structure. The chamfered structure enables the terminal part 200 to maintain good mechanical properties when bending, and ensures that there are no obvious wrinkles or fractures on the surface of the terminal part 200 after bending. The device part 330 of the flexible circuit board 300 is arranged opposite to the first profile 210 of the terminal part 200, and is arranged side by side with the terminal part 200 in the width direction X. The chamfered structures of the device part 330 and the terminal part 200 cooperate with each other to ensure the close fit between the device part 330 and the terminal part 200.

[0046] For further information, see Figure 4 The second profile includes a first sub-segment 321 and a second sub-segment 322. The first sub-segment 321 is aligned and parallel to the vertical segment 211, and the second sub-segment 322 is aligned and parallel to the inclined segment 212, so that the shape of the second profile matches the chamfered structure. It is also chamfered.

[0047] In this embodiment, the second profile of the flexible circuit board 300 is further subdivided into a first sub-segment 321 and a second sub-segment 322. The first sub-segment 321 is parallel to and aligned with the vertical segment 211 of the terminal portion 200, and the second sub-segment 322 is aligned with and parallel to the inclined segment 212 of the terminal portion 200. By so configuring, the second profile of the flexible circuit board 300 can be as close to the chamfered structure of the terminal portion 200 as possible without contacting the terminal portion 200, thereby ensuring the electrical effect and forming a more compact structural layout. The vertical segment 211 is arranged relative to the first sub-segment 321 to ensure a stable connection between the second profile and the terminal portion 200, while the inclined segment 212 is arranged relative to the second sub-segment 322. Through the chamfer transition, the overall structure of the terminal portion 200 and the flexible circuit board 300 is more in line with the miniaturization requirements of the module. The matching design between the chamfer and the second contour can not only increase the overall mechanical strength of the module, but also reduce the stress concentration on the terminal portion 200 and the flexible circuit board 300 caused by bending, so that the reliability of the electrical connection can be maintained after multiple bending.

[0048] In some embodiments, the flexible circuit board 300 includes an escape portion, and the device portion 330 is connected to the connecting portion 310 via the escape portion 340. The width of the escape portion 340 in the length direction Y is smaller than the width of the connecting portion 310 in the length direction Y, so that there is a step difference between the escape portion 340 and the connecting portion 310 in the length direction Y, and the space defined by the step difference is the escape position. The side of the terminal portion 200 away from the bending portion 112 includes a chamfered section 214 and a non-chamfered section 215, the chamfered section 214 is located at the step difference and the chamfered section 214 is spaced apart from the escape portion 340, that is, the chamfered section 214 is located in the escape position. At least a portion of the non-chamfered section 215 is connected to the connecting portion 310. The chamfered structure is located in the avoidance position, which effectively prevents the corners of the terminal part 200 facing the device part 330 from contacting the flexible circuit board 300 and causing problems in the circuit. The avoidance position can accommodate the corners of the terminal part 200, and there is no need to increase the distance between the flexible circuit board 300 and the terminal part 200 due to the corners, making the structure more compact.

[0049] For the technical solution in which the first contour 210 includes a vertical section 211 and an inclined section 212, that is, the terminal portion 200 has a chamfered structure, compared with the terminal portion 200 being rectangular, the flexible circuit board 300 that can be set in the width direction X is larger, which is more conducive to the miniaturization of the display module. In addition, the terminal portion 200 is provided with a chamfered structure and combined with the flexible circuit board 300 structure in this application, in display modules of size 8 and above, more space can be saved. For details, see Figure 5 .exist Figure 5 In the embodiment, the terminal portion 200 is chamfered on the side away from the flexible circuit board 300 along the width direction X, so that the display panel 100 can expose more area in the width direction X, providing more space for the arrangement of other components. The larger the display module size, the larger the space provided for other components, and the more obvious the space that can be saved. It should be noted that although Figure 5 The second contour 320 of the device portion 330 of the flexible circuit board 300 shown in the figure is a segment, and the first contour 210 of the terminal portion 200 is also a segment, and no chamfered structure is set. However, in other embodiments, the first contour 210 of the terminal portion 200 can still be set as a vertical segment 211 and an inclined segment 212, and the second contour 320 can still be set as a first sub-segment 321 and a second sub-segment 322, thereby forming a second contour 320 and a chamfered structure with shapes matching each other.

[0050] In some embodiments, the distance between the device portion 330 and the terminal portion 200 is not less than 0.2 mm, the distance between the device portion 330 and the edge 111 is not less than 0.2 mm, and the distance between the avoidance portion 340 and the chamfered section 214 is not less than 0.2 mm, leaving sufficient spacing between the device portion 330 and the terminal portion 200 to prevent electrical interference and to prevent the flexible circuit board 300 from being affected by laser cutting and failing during laser cutting.

[0051] The embodiment of the present application further provides a display device (not shown in the figure), which includes the display module described in any of the above embodiments. By using the display module provided in the above embodiments, the display device can make the structure of the display device more compact and achieve miniaturization.

[0052] It should be noted that in order to simplify the description of the embodiments of the present application and thus help understand one or more embodiments, in the above description of the embodiments, multiple features are sometimes combined into one embodiment, figure or description thereof. However, this method of expression does not mean that the features required by the object of the present application are more than the features mentioned in the claims. In fact, the features of the embodiments are less than all the features of the single embodiment disclosed above.
