Electric elargol can be obtained and conducting particles (for example, silver powder) is added in matrix resin, and by increasing conducting particles
Content (for example, 70% or more silver powder content) can have preferable electric conductivity.It, can when realizing electrical connection using conductive silver glue
Conductive silver glue is dripped and passes through hot setting in the end of the first first signal lead 21, the first second signal lead 22 and connecting lead wire 30
Bonding is realized, to provide stable electrical connection.And conductive tape can be metal foil or conductive fabric with highly conductive gum,
It is made of, can be electrically connected with conductor surface with bonding way realization conductive gum and conductive base.Wherein, when using conductive tape
When realizing electrical connection, it can be affixed directly to the end of the first first signal lead 21, the first second signal lead 22 and connecting lead wire 30,
Simple process, and it is not vulnerable.It should be noted that the first first signal lead 21 and the first second signal lead 22 can also pass through
ACF (Anisotropic Conductive Film, anisotropic conductive film) is electrically connected with connecting lead wire one-to-one correspondence, this Shen
Please to this without specifically limiting.Optionally, Fig. 5 is shown first in display panel 100 provided by the embodiment of the present application
After folding part 11 and the second folding part 12 fold, another top view of display panel 100, which further includes soft
Property wiring board 41, flexible circuit board 41 are located at second side of flexible base board 10, and connecting lead wire 30 is distributed in flexible circuit board 41.
Specifically, Fig. 5 is referred to, which introduces flexible circuit board 41 in second side of flexible base board 10, connection
Lead 30 is distributed on the flexible circuit board, and flexible circuit board is bundled in second side of flexible base board 10, it is possible to understand that, when adopting
When being electrically connected with flexible circuit board to the first first signal lead 21 and the first second signal lead 22, the first first signal lead and
First second signal lead can be respectively by binding, to realize signal with the pad at the connecting lead wire both ends on flexible circuit board
The electrical connection of cabling.Such mode, flexible circuit board 41 can be produced independently of flexible base board 10, the complete flexible circuitry of mass production
Flexible circuit board 41 and flexible base board 10 are bound again after plate 41, form connecting lead wire by the way of flexible circuit board 41
It, can be on display panel 100 when the failure of connecting lead wire 30 on display panel 100 can not form electrical connection when 30
The flexible circuit board 41 of binding is replaced, thus is conducive to promote product yield.
Optionally, Fig. 6 is shown the first folding part 11 and second in display panel 100 provided by the embodiment of the present application
Another top view of display panel 100 after folding part 12 folds, in display panel 100 provided by the embodiment of the present application, the
One signal lead 20 includes data line 70.
Specifically, refer to Fig. 6, in general, display panel 100 main part 13 be provided with extend in a first direction it is more
Data line 70, under visual angle shown in Fig. 6, each data line 70 respectively with the control that is located at 100 bottom non-display area of display panel
Chip 91 is electrically connected, and each data line 70 is used for when display panel 100 realizes display function, provides data letter to each sub-pixel
Number.In conjunction with Fig. 6 and Fig. 3, the first signal lead 20 mentioned in the embodiment of the present application includes above-mentioned data line 70, from main part
13 extend to the data line 70 of the first folding part 11 and the second folding part 12 in the first folding part 11 and the bending of the second folding part 12
To flexible base board 10 second side when, electrical connection is realized by connecting lead wire 30 in second side of flexible base board 10, in this way,
Under visual angle shown in Fig. 6, the data line 70 positioned at 40 the upper side and lower side of notch section corresponds electrical connection, and control chip 91 is led to
It crosses the data line 70 positioned at 40 downside of notch section and transmits data-signal to the data line 70 being located on the upside of notch, without in notch section
40 corresponding positions carry out coiling, therefore while realizing that display panel 100 is normally shown, also help and realize narrow frame
Design, meanwhile, data line 70 is not necessarily to also help alleviation in the prior art due to lesser in the mode of 40 coiling of notch section
Frame region carries out caused by intensive coiling cross-interference issue between data line 70, so be conducive to reduce due to data line 70 it
Between crosstalk caused by display bad phenomenon generation, and then also help promoted display panel 100 display effect.It needs
Illustrate, Fig. 6 only illustrates the segment data line 70 on display panel 100, does not represent actual quantity and size.
Optionally, continuing with referring to Fig. 6, in display panel 100 provided by the embodiment of the present application, the first signal lead 20
Including power supply line 80.
Specifically, continuing with referring to Fig. 6, in general, the main part 13 in display panel 100 is provided with and extends in a first direction
A plurality of power supply line 80, under visual angle shown in Fig. 6, each power supply line 80 respectively and is located at 100 bottom non-display area of display panel
It controls chip 91 to be electrically connected, each power supply line 80 is used to provide power supply signal for each sub-pixel, maintains sub-pixel within a certain period of time
Power supply needed for display.In conjunction with Fig. 6 and Fig. 3, the first signal lead 20 mentioned in the embodiment of the present application includes above-mentioned power supply
Line 80 extends to the power supply line 80 of the first folding part 11 and the second folding part 12 in the first folding part 11 and second from main part 13
When folding part 12 is bent to second side of flexible base board 10, electricity is realized by connecting lead wire 30 in second side of flexible base board 10
Connection, in this way, the power supply line 80 positioned at 40 the upper side and lower side of notch section corresponds electrical connection, control under visual angle shown in Fig. 6
Chip 91 is able to transmit power supply signal to the power supply line 80 being located on the upside of notch by the power supply line 80 for being located at 40 downside of notch section,
Without carrying out coiling in the corresponding position of notch section 40, therefore while realizing that display panel 100 is normally shown, also help
Realize the design of narrow frame, meanwhile, power supply line 80 is not necessarily to also help alleviation in the prior art in the mode of 40 coiling of notch section
Due to caused by lesser frame region carries out intensive coiling between power supply line 80 or power supply line 80 and other signals line it
Between cross-interference issue, and then be conducive to reduce the crosstalk institute by between power supply line 80 or between power supply line 80 and other signals line
The generation of caused display bad phenomenon, and then also help the display effect for promoting display panel 100.It should be noted that
