Detailed Description
Example 1
Referring to fig. 2, the display panel 10 provided in the present embodiment may be a liquid crystal display panel, an inorganic light emitting diode display panel, an organic light emitting diode display panel, or the like.
With continued reference to fig. 2, the display panel 10 includes a substrate 11, and the substrate 11 defines a display area AA and a non-display area NA located at one side of the display area AA, where the display area AA is connected to the non-display area NA. In some other embodiments, the non-display area NA may be also arranged in a frame shape in such a manner as to surround the display area AA. The display area AA is an area for displaying images when the display panel 10 is in an operating state, and the non-display area NA is not used for displaying images, and is used for arranging wiring, drivers and other circuit structures inside the display panel 10.
The display panel 10 further includes a flexible circuit board 12 and a driver 13. The flexible circuit board 12 is partially disposed in the non-display area NA, specifically, one end of the flexible circuit board 12 is disposed in the non-display area NA of the substrate 11, and is used for electrically connecting with the driver 13 in the non-display area NA, and the other end of the flexible circuit board 12 can be electrically connected with a motherboard (not shown) of the display panel 10. The driver 13 is disposed in the non-display area NA. In this embodiment, the driver 13 is a driving chip.
With continued reference to fig. 2, the flexible circuit 12 includes a main body 120 and two extending portions 121 and 122 extending from one end of the main body 120 at intervals, the main body 120 is located at one side of the driver 13 away from the display area AA, and the extending portions 121 and 122 extend along two opposite sides of the driver 13 toward the display area AA. And the extension 121 and the extension 122 are electrically connected to a side of the driver 13 adjacent to the display area AA, respectively.
In this embodiment, the "side of the driver 13 adjacent to the display area AA" refers to a portion of the driver 13 near the upper edge 130 of the display area AA to about 1/4 height line 15 of the driver 13, based on the orientation of the viewer when viewing the display panel 10 shown in fig. 2; in other embodiments, the "side of the driver 13 adjacent to the display area AA" refers to a portion of the driver 13 above the center line 16 along the longitudinal direction. "opposite sides of the driver 13" means left and right sides of the driver 13 when a viewer views the display panel 10 shown in fig. 1. The extension 121 and the extension 122 extend from the left and right sides of the driver 13 toward the display area AA, respectively, such that a lower edge 134 of the driver 13 on a side away from the display area AA is located in the space 17 between the extension 121 and the extension 122, and ends of the extension 121 and the extension 122 are electrically connected to a side of the driver 13 adjacent to the display area AA. When the ends of the extension 121 and the extension 122 are electrically connected to a side of the driver 13 adjacent to the display area AA, the driver 13 is partially surrounded by the flexible circuit board 12.
The driver 13 is further electrically connected to the display area AA, so that the driver 13 is configured to receive an electrical signal generated by the flexible circuit board 12, process the electrical signal, and output the processed electrical signal to the display area AA, or may also be configured to receive a signal from the display area AA and transmit the signal to the flexible circuit board 12.
Referring to fig. 3, a plurality of first pins 131 and a plurality of second pins 132 are disposed on a side of the driver 13 adjacent to the display area AA. The second pins 132 are respectively disposed on two sides of the first pins 131. In this embodiment, the number of the second pins 132 located at both sides of the plurality of first pins 131 is equal. In other embodiments, the number of the second pins 132 located at two sides of the plurality of first pins 131 may be unequal. The "both sides of the plurality of first pins 131" refers to both left and right sides of the plurality of first pins 131 when viewing fig. 2 from a viewer.
Each first pin 131 is electrically connected to the display area AA, wherein a structure (not shown) for implementing image display is disposed in the display area AA, and at least part of the first pins 131 are used for outputting display signals; in another embodiment, the display area AA is provided with a structure (not shown) for displaying images and a structure (not shown) for realizing touch functions at the same time, and part of the first pins 131 are used for outputting display signals and part of the first pins 131 are used for outputting/receiving touch signals. The display signals may include, but are not limited to, gate driving signals, source driving signals, etc., and the touch signals may include, but are not limited to, touch scanning signals, touch sensing signals, etc.
In this embodiment, the plurality of first pins 131 are arranged in two rows with the same extending direction in the non-display area NA. The electrical connection line between each first pin 131 and the display area AA is located between two adjacent first pins 131 not belonging to the same row as the first pin 131, so as to avoid overlapping of the electrical connection lines between different first pins 131 and the display area AA, thereby being beneficial to rationalizing the layout of the electrical connection lines and saving the NA space of the non-display area.
Each second pin 132 is electrically connected to one of the extending portions of the flexible circuit board 12, and is used for supporting the transmission of electrical signals between the driver 13 and the flexible circuit board 12. And the second pins 132 located on the same side of the plurality of first pins 131 are electrically connected to the same extension 121/122. In this embodiment, each of the second pins 132 is electrically connected to an extension 121/122 that is more adjacent thereto. In detail, with reference to the observer of fig. 2, each of the second pins 132 located at the left side of the plurality of first pins 131 is electrically connected to the extension portion 121 of the flexible circuit board 12, and each of the second pins 132 located at the right side of the plurality of first pins 131 is electrically connected to the extension portion 122 of the flexible circuit board 12.
With continued reference to fig. 3, in this embodiment, a side of the driver 13 away from the display area AA is also electrically connected to the extension 121 and the extension 122 of the flexible circuit board 12. Specifically, a plurality of third pins 133 are disposed on a side of the driver 13 away from the display area AA, and each third pin 133 is electrically connected to the extension portion 121 and the extension portion 122 of the flexible circuit board 12. The second pins 132 and the third pins 133 are input/output pins of the driver 13 for supporting the transmission of electrical signals, such as power signals and data signals, with the flexible circuit board 12.
In the display panel 10 provided in this embodiment, the plurality of first pins 131 and the plurality of second pins 132 are disposed on the side of the driver 13 adjacent to the display area AA, and are electrically connected with the display area AA through the plurality of first pins and the plurality of second pins 132 and the flexible circuit board 12, so that wiring between the side of the driver 13 far from the display area AA and the flexible circuit board 12 in the reserved space of the non-display area NA is avoided, and the overall area of the non-display area NA is advantageously saved. Further, the area occupation ratio of the display area AA on the substrate 11 is increased, which is beneficial to improving the image display effect. In addition, even if the third pins 133 located on the side of the driver 13 far from the display area AA are electrically connected to the flexible circuit board 12, the area of the non-display area NA is not increased additionally because the wires when the third pins 133 are electrically connected to the flexible circuit board 12 are directly arranged by using the space between the extension portions 121 and 122 and the driver 13. And the number of input/output pins of the driver 13 can be increased by adding the third pin 133.
With reference to fig. 3, in the present embodiment, the extending portion 121 and the end portion of the extending portion 122 of the flexible circuit board 12 are both provided with a plurality of first connection pads 123 (electrical contact structures made of metal material), and the number of the first connection pads 123 disposed on the extending portion 121 and the extending portion 122 are equal. Each first connection pad 123 on the extension portion 121 is connected to each first connection pad 123 on the extension portion 122 through a conductive wire 14 in a one-to-one correspondence, and then is commonly connected to two third pins 133 through two different nodes on the conductive wire 14. That is, each first connection pad 123 of the extension portion 121 is connected in series with one first connection pad 123 of the extension portion 122 through a conductive wire 14, and two nodes of the conductive wire 14 are respectively electrically connected to one third pin 133. That is, on the side of the driver 13 away from the display area AA, each third pin 133 is electrically connected to a first connection pad 123 on the extension 121 and the extension 122, and in particular, each third pin 133 is electrically connected to a conductive line 14, and the conductive line 14 is electrically connected to a first connection pad 123 on the extension 121 and the extension 122.
In the above manner of connecting each third pin 133 to two first connection pads 123 on the flexible circuit board 12, a parallel structure is formed between each third pin 133 and the flexible circuit board 12, which is beneficial to reducing the total resistance of the wires between the third pins 133 and the flexible circuit board 12, and further enhancing the strength of the electrical signals input or output by each third pin 133.
In this embodiment, in addition to the first connection pads 123, the second connection pads 124 are further disposed at the ends of the extension portion 121 and the extension portion 122 of the flexible circuit board 12 to establish electrical connection with the second pins 132.
Referring to fig. 4, in a modified embodiment of the present invention, a portion of the first connection pads 123 on the extension portion 121 and the extension portion 122 of the flexible circuit board 12 are electrically connected to another first connection pad 123 through the conductive wires 14, and then are electrically connected to a third pin 133 through two nodes on the conductive wires 14, and another portion of the first connection pads 123 are electrically connected to only a third pin 133 on the driver 13, but are not electrically connected to other first connection pads 123. That is, part of the third pins 133 of the driver 13 is electrically connected to one of the first connection pads 123 of the extension portion 121 and the extension portion 122, and the other part of the third pins 133 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. 5, in another modified embodiment of the 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 connected to only one third pin 133 on the driver 13. That is, each third pin 133 of the driver 13 is electrically connected to only one first connection pad 123 of one of the extending portions (121 or 122) of the flexible circuit board 12.
Referring to fig. 6, in a further 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 of the modified embodiment shown in fig. 4 to 6, the wiring between the side of the non-display area NA reserved space for the driver 13 away from the display area AA and the flexible circuit board 12 is avoided, so that 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 for improving the image display effect of the display panel 10.
It will be appreciated by persons skilled in the art that the above embodiments have been provided for the purpose of illustrating the invention and are not to be construed as limiting the invention, and that suitable modifications and variations of the above embodiments are within the scope of the invention as claimed.
