That is, a portion of the third pins 133 on the driver 13 is electrically connected to the extension portion 121 and a first connection pad 123 on the extension portion 122, and another portion of the third pins 133 is electrically connected to only a first connection pad 123 on one of the extension portions (121 or 122) on the flexible circuit board 12.
Referring to fig. 5, in another modified embodiment of the present invention, each of the first connection pads 123 on the extension portion 121 and the extension portion 122 of the flexible circuit board 12 is not electrically connected to another first connection pad 123 through a wire, but is only connected to a third pin 133 on the driver 13. That is, each of the third pins 133 of the driver 13 is electrically connected to only one of the first connection pads 123 of one of the extension portions (121 or 122) of the flexible circuit board 12.
Referring to fig. 6, in another modified embodiment of the present invention, the third pins 133 are not disposed on the driver 13, and the first connection pads 123 are not disposed on the flexible circuit board 12, so that the flexible circuit board 12 is electrically connected to the second pins 132 of the driver 13 only through the second connection pads 124 of the extension portions 121 and 122.
It should be understood that, in the display panel 10 in the modified embodiment shown in fig. 4 to fig. 6, since the space reserved in the non-display area NA for the wiring between the side of the driver 13 away from the display area AA and the flexible circuit board 12 is avoided, the area of the non-display area NA is advantageously reduced, and the area ratio of the display area AA on the substrate 11 is increased, which is advantageous to improve the image display effect of the display panel 10.
It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be taken as limiting the present invention, and that suitable modifications and variations of the above embodiments are within the scope of the invention as claimed.
