The outside of the first side S1 of the DA refers to the first quadrant, the term "outside of the second side S2 of the display area DA" refers to the third quadrant, and the term "display area DA" refers to the fourth quadrant.

FIG. 3 is a schematic cross-sectional view along line 3A-3B and line 3B-3C of FIG. 2 . Refer to FIG. 2 and FIG. 3 at the same time. In some embodiments, the display panel 100 further includes an auxiliary signal line 150A and an insulating layer 170 .

The hole 172 and the second through hole 174 are electrically coupled to the signal line 150 . In this way, although the width of the first extension section 154 of the signal line 150 is relatively narrow, the setting of the auxiliary signal line 150A can reduce the resistance of signal transmission, which is equivalent to increasing the size of the cross-sectional area of the signal transmission path, and avoiding excessive resistance due to High and prone to high temperature conditions.

Here, the auxiliary signal line 150A has an opening 150B corresponding to the first through hole 172 of the insulating layer 170 , and the conductive adhesive 210 is filled into the opening 150B and the first through hole 172 .

As mentioned above, the auxiliary signal line 150A does not cover the second portion P2 of the first extension section 154-Z, thereby allowing the second portion P2 of the first extension section 154-Z to be connected to the wire 200, so that the signal line 150 The ESD protection element 190 is electrically coupled through the wire 200 . In this way, the insulating layer 170 and the protective layer 180 are arranged between the wire 200 and the signal wire 150. Referring to FIGS. The wire 200 of 150 interacts with the signal line 150 (crosstalk). Here, in order to effectively avoid mutual interference, a double-layer (insulation layer 170 and protection layer 180 ) design is adopted between the wire 200 and the signal wire 150 .

The sides are parallel. In various embodiments of the present invention, the maximum widths of the first extension sections 154-1 of the signal lines 150-1˜150-n have little difference. For example, the maximum width W1 of the first extension section 154-1 of the signal line 150-1 is 1.5 to 5 times the maximum width W2 of the first extension section 154-1 of the signal line 150-2. What's more, the maximum width W1 of the first extension section 154-1 of the signal line 150-1 is 1.5 to 3 times or 2 to 3 times the maximum width W2 of the first extension section 154-1 of the signal line 150-2 . Here, the signal line 150-1 is closer to the source fan-out line 134 than the signal line 150-2. For example, the signal line 150-1 is the one of the signal lines 150 closest to the display area DA, and the signal line 150-2 It is the one next to the display area DA of the signal line 150 . Here, the signal line 150 - 1 may be a power line, such as a COM power line for providing a ground potential, and the signal line 150 - 2 may provide timing signals to control the gate driver 142 to output scan signals in timing. In other embodiments, the maximum width W1 of the first extension section 154-1 of the signal line 150-1 may be 1.5 times the maximum width of the first extension section 154-1 of one of the signal lines 150-3˜150-n. to 5 times.

In some embodiments, two opposite sides of at least one of the first extension segments 154 are parallel to sides of the source fan-out line 134 . As shown in the figure, the source fan-out line 134 includes a plurality of fan-out wires 134-1˜134-n. sides parallel.

Through the above configuration, the width of each signal line 150 - 1 - 150 - n can be averaged, avoiding the problem that the resistance of some signal lines 150 - 1 - 150 - n is too small and the resistance is too high.

And avoid the situation where the resistance is too high and it is easy to generate high temperature.

Other details of this implementation manner are as large as those described in the implementation manner of FIG. 1 , and will not be repeated here.

FIG. 6 is a schematic top view of a display panel 100 according to yet another embodiment of the present invention. This embodiment is similar to the aforementioned embodiment of FIG. 1 , the difference is that in this embodiment, the first extension section 154 includes first extension sections 154-1, 154-2, 154-Z, and the second extension section 156 includes the first extension section 154-Z. Two extensions 156-1, 156-Z.

In some embodiments of the present invention, one end of the first extension section 154-1 is connected to the first connecting section 152, the other end of the first extension section 154-1 is connected to the first extension section 154-2, and the first extension section 154-2 An end away from the first extension section 154-1 is connected to the first extension section 154-Z.

As mentioned above, the extension line of each first extension section 154 has an included angle with the extension line EL2 of the first connection section 152 , and the included angle gradually becomes larger as the distance away from the first connection section 152 . For example, the extension line of the first extension section 154-1 and the extension line EL2 of the first connection section 152 have an included angle Aa, and the extension line of the first extension section 154-2 and the extension line EL2 of the first connection section 152 have an angle Aa. For the included angle Ab, the extension line of the first extension section 154 -Z and the extension line EL2 of the first connecting section 152 have an included angle Az. From being adjacent to the first connecting section 152 to being away from the first connecting section 152 , the included angle gradually becomes larger, for example, the included angle Aa, the included angle Ab, and the included angle Az become larger sequentially. In this way, the purpose of line transfer can be achieved in a limited space while maintaining the width of the signal line 150 as much as possible.

In some embodiments of the present invention, the plurality of second extension sections 156-1, 156-Z are defined as a plurality of sequentially connected regions where the signal line 150 extends from the first extension section 154 to connect to the second connection section 158 part. For example, here, one end of the second extension section 156 - 1 is connected to the first extension section 154 , and the other end of the second extension section 156 - 1 is connected to the second extension section 156 -Z.

In various embodiments of the present invention, the extension line of each second extension section 156 has an included angle with the extension line EL2 of the first connection section 152 , and the included angle gradually becomes smaller as it gets away from the first connection section 152 . For example, the extension line of the second extension section 156-1 and the extension line EL2 of the first connection section 152 have an included angle Ba, and the extension line of the second extension section 156-Z and the extension line EL2 of the first connection section 152 have an angle Ba. Angle Bz. From adjacent to the first connecting section 152 to away from the first connecting section 152 , the included angle becomes gradually smaller, for example, the included angle Bz is smaller than the included angle Ba. In this way, the purpose of line transfer can be achieved in a limited space while maintaining the width of the signal line 150 as much as possible.

Herein, the so-called extension lines (such as the extension line EL2 of the first connecting section 152, the extension line of the first extension section 154, and the extension line of the second extension section) refer to the opposite sides of the element. middle line. The so-called angles (such as angles Aa, Ab, Az, Ba, Bz) refer to the rotation angles of the front and rear ends of the component relative to the front and rear ends of the signal line 150 (ie, the first connecting section 152 ).

Other details of this implementation manner are as large as those described in the implementation manner of FIG. 1 , and will not be repeated here.

In some implementations of the present invention, the signal line is designed with a special wire transfer mechanism, which can improve the problem of excessive resistance of the signal line while maintaining the design of the narrow frame.

Certainly, the present invention also can have other various embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes All changes and modifications should belong to the protection scope of the claims of the present invention.
