Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0018] In the structure of FIG1 , because one end of the second electrical connector 170 overlaps the color filter substrate 120 and the other end overlaps the circuit board 150, the second electrical connector 170 and the first electrical connector 160 partially overlap. However, because no isolating member is provided between the first electrical connector 160 and the second electrical connector 170 to separate them, signal crosstalk may occur between the first electrical connector 160 and the second electrical connector 170. This application proposes the following technical solutions to address the aforementioned technical issues.

[0019] 2 to 5 , the present application proposes a display device 200 , which includes a display area AA and a non-display area NA located outside the display area AA.

[0021] 2 , the display device 200 may further include a first electrical connector 250 and a second electrical connector 260 , wherein the plurality of first driving terminals 211 are electrically connected to the plurality of second driving terminals 241 via the first electrical connector 250 , and the plurality of first touch terminals 212 are electrically connected to the plurality of second touch terminals 242 via the second electrical connector 260 .

Although the first electrical connector 250 and the second electrical connector 260 overlap in some areas, the first electrical connector 250 and the second electrical connector are separated by the array substrate 210 and the circuit board 240, thereby avoiding the technical problem of crosstalk between the touch signal and the driving signal between the first electrical connector 250 and the second electrical connector 260.

[0023] It should be noted that the display device 200 of the present application may be a liquid crystal display device, an organic light emitting display device, or an inorganic light emitting display device. The following embodiments are described using the liquid crystal display device as an example.

[0024] It should be noted that the first electrical connector 250 and the second electrical connector 260 of the present application can be different ones of the flexible circuit board 240 or the flip chip film. The present application takes the first electrical connector 250 as the flexible circuit board 240 and the second electrical connector 260 as the flip chip film as an example for explanation.

[0025] The technical solution of this application is now described in conjunction with specific embodiments.

[0026] Referring to Figure 3 , the display panel 300 may include an array substrate 210, a color filter substrate 220 disposed opposite the array substrate 210, and a liquid crystal layer LC disposed between the array substrate 210 and the color filter substrate 220. The array substrate 210 may be a conventional array substrate 210 or a COA (Color Filter On Array) substrate. In the following embodiments, this application uses a conventional array substrate 210 as an example for description.

[0027] 3 , the array substrate 210 may include a first substrate 213 and a thin film transistor layer 214 located on the first substrate 213. The first substrate 213 may be made of glass, quartz, polyimide or other materials.

[0028] In this embodiment, the thin film transistor layer 214 may include a plurality of thin film transistors. The thin film transistors may be of an etch stop type, a back channel etch type, or may be classified into a bottom gate thin film transistor, a top gate thin film transistor, or other structures according to the position of the gate and the active layer 214c. For example, a bottom gate thin film transistor may include a gate layer 214a located on the first substrate 213, a gate insulating layer 214b located on the gate layer 214a, an active layer 214c located on the gate insulating layer 214b, a source and drain electrode layer 214d located on the active layer 214c, a planar layer 214e located on the source and drain electrode layer 214d, and a pixel electrode layer 214f ​​located on the planar layer 214e.

The electric field formed by the common electrode layer 213 and the pixel electrode layer 214f ​​drives the liquid crystal molecules in the liquid crystal layer LC to deflect.

[0030] Please refer to Figures 2 and 3. The display panel 300 also includes a first polarizer 271 and a second polarizer 272 arranged on both sides of the display panel 300. The first polarizer 271 is arranged on the side of the color filter substrate 220 away from the array substrate 210, and the second polarizer 272 is arranged on the side of the array substrate 210 away from the color filter substrate 220.

[0031] In this embodiment, since the second polarizer 272 is arranged close to the backlight module 400 in the display device 200, and there is a partial structure in the backlight module 400 that contacts the display panel 300, in order to avoid interference between the second polarizer 272 and the backlight module 400, the area of ​​the first polarizer 271 of the present application can be larger than the area of ​​the second polarizer 272, which is equivalent to reducing the area of ​​the second polarizer 272.

[0032] 2 , a driving chip 215 is further provided on the first surface 210 a of the array substrate 210 . The driving chip 215 is disposed between the color filter substrate 220 and the first electrical connector 250 . The driving chip 215 is mainly used to receive and transmit driving signals for displaying by the display device 200 .

[0033] Referring to Figure 3, the display device 200 may further include a touch layer 230 integrated into the display panel 300. The touch layer 230 may be disposed between the second polarizer 272 and the first substrate 213. The touch layer 230 may include a first touch metal layer 231 and a second touch metal layer 232 disposed on a side of the first substrate 213 away from the color film substrate 220, as well as a first insulating layer 233 disposed between the first touch metal layer 231 and the second touch metal layer 232, and a second insulating layer 234 disposed on a side of the second touch metal layer 232 away from the first touch metal layer 231.

[0035] In this embodiment, the touch layer 230 provided in this embodiment of the present application may be of a mutual capacitance type or a self capacitance type.

[0036] In this embodiment, if the touch layer 230 is of a mutual capacitance type, the first touch metal layer 231 may include a plurality of first electrodes and a plurality of second electrodes. The plurality of first electrodes are connected via first connecting bridges located in the first touch metal layer 231, and the plurality of second electrodes are connected via second connecting bridges located in the second touch metal layer 232, passing through the insulating layer. If the touch layer 230 is of a self-capacitive type, the first touch metal layer 231 may include a plurality of touch electrodes distributed in an array, and the second touch metal layer 232 may include a plurality of touch traces, with each touch trace correspondingly connected to a touch electrode.

[0037] In this embodiment, when the touch layer 230 is self-capacitive, the touch layer 230 may also include only one metal layer, that is, the metal layer includes multiple touch electrodes and multiple touch traces located between adjacent touch electrodes, and each touch trace is correspondingly connected to a touch electrode. The embodiment of this application is only described above as an example, but is not limited to this. The specific type and structure of the touch layer 230 can be selected according to actual needs.

[0038] Referring to FIG. 2 , the display device 200 further includes a cover layer 280 disposed on the first polarizer 271 . The cover layer 280 may be made of a glass cover.

[0039] Please refer to Figures 2 and 3. A plurality of first driving terminals 211 are further provided on the surface of the first substrate 213 on the light-emitting side facing the display device 200. The material of the first driving terminals 211 can be composed of the conductive material of at least one of the gate layer 214a, the source and drain layer 214d and the pixel electrode layer 214f. A plurality of first touch terminals 212 are further provided on the surface of the first substrate 213 on the light-emitting side away from the display device 200. The material of the first touch terminals 212 can be composed of the conductive material in the touch layer 230.

[0040] In this embodiment, the plurality of first driving terminals 211 and the plurality of first touch terminals 212 may both be located in the binding area BD of the display device 200 . For example, both may be located in the binding area BD of the lower frame of the display device 200 .

[0041] Please refer to Figure 2, the circuit board 240 also includes a plurality of second driving terminals 241 provided on the third surface 240a and a plurality of second touch terminals 242 provided on the fourth surface 240b. The plurality of second driving terminals 241 and the plurality of second touch terminals 242 are both located on the side of the circuit board 240 close to the array substrate 210.

[0042] In this embodiment, the first electrical connector 250 electrically connects multiple first drive terminals 211 and multiple second drive terminals 241, a first drive terminal 211 and a second drive terminal 241 are correspondingly connected, and the two ends of the first electrical connector 250 are respectively provided with multiple connection terminals bound and connected to the corresponding drive terminals; the second electrical connector 260 electrically connects multiple first touch terminals 212 and multiple second touch terminals 242, a first touch terminal 212 and a second touch terminal 242 are correspondingly connected, and the two ends of the second electrical connector 260 are respectively provided with multiple connection terminals bound and connected to the corresponding touch terminals.

[0043] In this embodiment, anisotropic conductive adhesive may be provided between the first electrical connector 250 and the first drive terminals 211 and the second drive terminals 241, and anisotropic conductive adhesive may be provided between the second electrical connector 260 and the first touch terminals 212 and the second touch terminals 242, so that the terminals and the electrical connectors are only conductive in the longitudinal direction.

[0044] In this embodiment, the first surface 210a of the array substrate 210 and the third surface 240a of the circuit board 240 can be flush, that is, the first surface 210a and the third surface 240a can be located on the same horizontal plane, so that after the first electrical connector 250 is bound to the first driving terminal 211 and the second driving terminal 241, the surface of the first electrical connector 250 on the side closest to the light emitting direction of the display device 200 is flat. Secondly, depending on the position of the circuit board 240, the first surface 210a can also be higher or lower than the third surface 240a, which is not specifically limited in this application.

[0045] In this embodiment, the second electrical connector 260 may include a first sub-segment 261, a second sub-segment 262 and a third sub-segment 263 connected to each other, the first sub-segment 261 is electrically connected to multiple first touch terminals 212, the third sub-segment 263 is electrically connected to multiple second touch terminals 242, and the second sub-segment 262 is in contact with at most a portion of the side surface of the circuit board 240 close to the array substrate 210.

[0046] Please refer to Figure 2. Since the thickness of the circuit board 240 is greater than the thickness of the array substrate 210, when the second electrical connector 260 is bound, the second electrical connector 260 needs to be bent so that the first sub-segment 261 and the multiple first touch terminals 212 are electrically connected, and the third sub-segment 263 and the multiple second touch terminals 242 are electrically connected.

[0047] At the same time, the second sub-segment 262 and the first sub-segment 261 are arranged at an angle, and the second sub-segment 262 and the third sub-segment 263 are arranged at an angle; for example, in the structure of Figure 2, the second sub-segment 262 and the first sub-segment 261 and the third sub-segment 263 are all arranged perpendicularly; or, the angles between the second sub-segment 262 and the first sub-segment 261 and the third sub-segment 263 are all obtuse angles, that is, the second sub-segment 262 is inclined toward one side of the array substrate 210; or, the second sub-segment 262 and the side of the circuit board 240 close to the array substrate 210 are separated; or, referring to Figure 4, the portion of the second sub-segment 262 close to the third surface 240a and the side of the circuit board 240 close to the array substrate 210 are separated, and the portion of the second sub-segment 262 close to the fourth surface 240b is in contact with the side of the circuit board 240 close to the array substrate 210.

[0048] In this embodiment, since no glue is set between the second sub-segment 262 and the circuit board 240, the second sub-segment 262 and the circuit board 240 are easy to separate. The present application can set glue between the second sub-segment 262 and the side of the circuit board 240 facing the array substrate 210 to make the second sub-segment 262 and the circuit board 240 adhere to each other, so as to improve the fastness of the second sub-segment 262 and the circuit board 240.

[0049] 2 , a touch chip 235 is provided on the surface of the first subsection 261 near the array substrate 210. The touch chip 235 is located between the array substrate 210 and the circuit board 240. The touch chip 235 is mainly used to receive and transmit touch signals required for touch control of the display device 200.

[0050] 2 , one end of the first sub-segment 261 away from the second sub-segment 262 may extend toward the display area AA of the display device 200 , and the first sub-segment 261 and the color filter substrate 220 at least partially overlap.

[0051] In the prior art, the touch layer 230 is usually arranged on the side of the color filter substrate 220 facing the light-emitting direction. At the same time, a polarizer is also provided on the touch layer 230. At the same time, the area of ​​the color filter substrate 220 is also smaller than the area of ​​the array substrate 210. Therefore, the connection area between the flexible circuit board 240 and the touch terminal on the color filter substrate 220 is limited, resulting in technical problems such as abnormal binding connection.

[0052] In this embodiment, the first sub-segment 261 extends from the edge of the array substrate 210 on the side close to the circuit board 240 toward the display area AA of the display device 200, and at least partially overlaps with the color filter substrate 220; that is, the present application increases the contact area between the first sub-segment 261 and the side of the array substrate 210 away from the light emitting direction, the length of the first touch terminal 212 can be increased, and the contact area between the first electrical connector 250 and the first touch terminal 212 is also increased, thereby avoiding the technical problem of abnormal binding between the first electrical connector 250 and the first touch terminal 212.

[0053] Referring to FIG. 5 , compared to the structure of FIG. 2 , the first subsegment 261 of the present application can further extend toward the display area AA of the display device 200, so that the first subsegment 261 and the first polarizer 271 at least partially overlap. That is, based on FIG. 2 , the area of ​​the first subsegment 261 of the present application is further increased, and the length of the first touch terminal 212 can be further increased.

[0054] It should be noted that the first subsegment 261 cannot extend too far toward the display area AA of the display device 200 . For example, the distance between the end of the first subsegment 261 away from the second subsegment 262 and the second polarizer 272 is at least 1 mm.

[0055] It should be noted that since the first touch terminal 212 can be set on the side of the array substrate 210 away from the color filter substrate 220, there is no need to reserve a certain space on the color filter substrate 220 to set the first touch terminal 212, and the edge of the polarizer can be flush with the edge of the color filter substrate 220.

[0056] It should be noted that the length in this application refers to the dimension in the direction from the array substrate 210 to the circuit board 240 .

[0057] 2 and 5 , a plurality of components 243 are further provided on the third surface 240 a of the circuit board 240 . The plurality of components 243 are provided on a side of the plurality of second driving terminals 241 away from the array substrate 210 , and the third sub-segment 263 overlaps with at least part of the components 243 .

[0058] In this embodiment, the component 243 may be a resistor, a capacitor or other device.

[0059] In this embodiment, since the second touch terminal 242 of the present application is arranged on the fourth surface 240b of the circuit board 240, there is no need to prepare the second touch terminal 242 on the third surface 240a of the circuit board 240. The width of the circuit board 240 of the present application in the direction from the array substrate 210 to the circuit board 240 can be reduced, thereby shortening the size of the frame of the display device 200 of the present application and realizing a narrow frame design.

[0060] In this embodiment, compared with the structure of FIG. 1 , the width of the circuit of the present application can be reduced by 7 mm to 10 mm.

[0061] In this embodiment, since the third sub-segment 263 is bound and connected to multiple second touch terminals 242, in order to improve the binding effect between the third sub-segment 263 and the second touch terminals 242, the present application can increase the length of the second touch terminal 242 in the direction from the array substrate 210 to the circuit board 240, that is, the length of the second touch terminal 242 can be greater than the length of the second driving terminal 241, so that the third sub-segment 263 overlaps with at least part of the component 243, thereby increasing the binding area between the second touch terminal 242 and the third sub-segment 263, and avoiding the technical problem of abnormal binding between the third sub-segment 263 and multiple second touch terminals 242.

[0062] In this embodiment, since the backlight module 400 is also provided on the side of the first sub-segment 261 away from the array substrate 210, compared with the first sub-segment 261, the side of the third sub-segment 263 away from the circuit board 240 does not have a support member. Due to the action of gravity, the third sub-segment 263 is easily peeled off from the circuit board 240. The present application can increase the contact area between the third sub-segment 263 and the circuit board 240, so that the end of the third sub-segment 263 away from the second sub-segment 262 continues to extend toward the end of the circuit board 240 away from the array substrate 210. For example, the positive projections of multiple components 243 on the third sub-segment 263 can be located within the third sub-segment 263.

[0063] In this embodiment, the contact area between the first sub-segment 261 and the array substrate 210 can be smaller than the contact area between the third sub-segment 263 and the circuit board 240, which is equivalent to increasing the contact area between the third sub-segment 263 and the circuit board 240, thereby improving the adhesion between the third sub-segment 263 and the circuit board 240 and avoiding the technical problem of peeling off between the third sub-segment 263 and the circuit board 240.

[0064] In this embodiment, since corresponding terminals are provided on the third surface 240a and the fourth surface 240b of the circuit board 240, the present application can enable the orthographic projections of multiple second driving terminals 241 on the third surface 240a of the circuit board 240 and the orthographic projections of multiple second touch terminals 242 on the third surface 240a of the circuit board 240 to be arranged in a non-overlapping manner; for example, in the structures of Figures 2 and 5, the second driving terminal 241 is arranged close to the array substrate 210, and the second touch terminal 242 is away from the array substrate 210. The setting of the second touch terminal 242 increases the length of the second electrical connector 260, increases the wiring space of the metal wire in the second electrical connector 260, and facilitates the arrangement of the metal wire in the second electrical connector 260.

[0065] In other embodiments, the orthographic projections of the plurality of second driving terminals 241 on the third surface 240 a of the circuit board 240 and the orthographic projections of the plurality of second touch terminals 242 on the third surface 240 a of the circuit board 240 may partially overlap.

[0066] Referring to Figures 2 to 5, the display device 200 also includes a backlight module 400 arranged on the side of the array substrate 210 facing away from the light-emitting side of the display device 200. The backlight module 400 includes a frame 410 and a first spacer layer 420 arranged on the frame 410. The first spacer layer 420 is in contact with the side of the first sub-segment 261 facing away from the array substrate 210.

[0067] In this embodiment, the backlight module 400 may include a plurality of light emitting devices 430 .
