Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
Fig. 3 is a schematic diagram showing the arrangement structure of the bump12 for connecting with the flexible printed circuit FPC on the display panel 1 in the prior art. In the prior art, the protruding portions 12 are arranged in a vertical or splayed shape in sequence along the length direction of the single-layer region 11 of the display panel 1, however, because the protruding portions 12 are used for meeting the length requirement of the electrical connection between the display panel 1 and the FPC, the protruding portion Bump12 of the arrangement structure cannot meet the requirement of a further narrow frame, and when the pull-out force test of the FPC2 is performed, as shown in fig. 2, the FPC2 is pulled upwards, the protruding portions 12 are pulled along the length direction, the effective contact area between the protruding portions and the display panel 1 and the FPC2 is small, and therefore the pull-out force test requirement of the FPC cannot be guaranteed.
Therefore, in order to solve the problems that the pulling force test requirement of the FPC cannot be effectively ensured on the premise that the narrow frame of the display panel is further realized, the requirement is contradicted and cannot be simultaneously met in the prior art, the invention provides the display panel, the flexible circuit board and the display device.
Specifically, a display panel is provided in a first embodiment of the present invention, and as shown in fig. 4, a schematic plan view of one implementation of the display panel in the first embodiment of the present invention. In the embodiment of the present invention, the display panel 100 includes a connection region 110 provided with a protrusion 111, wherein the protrusion 111 is used for electrically connecting the display panel 100 and the flexible printed circuit FPC, and in the embodiment of the present invention, the extending direction of the protrusion 111 is set according to the extending direction of the long side of the connection region 110. Specifically, the connection region 110 of the display panel 100 is a region of the display panel 100 for connection with an FPC. For example, when the display panel 100 is a liquid crystal display panel, as shown in fig. 5, the display panel 100 includes an array substrate 101 and a liquid crystal layer 102 disposed on the array substrate, it can be understood that the liquid crystal layer 102 is disposed corresponding to a display area of the array substrate, and the array substrate 101 includes a portion extending outward compared to the liquid crystal layer 102, and is formed as a single-layer area of the display panel 100 and a peripheral area corresponding to the array substrate 101, and the peripheral area is generally used for connecting with a Flexible Printed Circuit (FPC), that is, formed as a connection area 110 in an embodiment of the present invention.
It should be noted that, for display panels with different structural types, the specific structure of the display panel and the location of the connection area on the display panel for connecting with the flexible printed circuit board FPC will be understood by those skilled in the art, and will not be described in detail herein.
In addition, it should be noted that the protruding portion 111 for electrically connecting the display panel 100 and the flexible printed circuit board FPC is generally an electrical connection end extending along one direction and having a certain length; for the connection area 110, the connection area 110 is formed in a long shape to meet the narrow frame requirement of the display panel 100, so that the long connection area 110 includes a long side and a short side. In the embodiment of the present invention, the extending direction of the protruding portion 111 is set according to the extending direction of the long side of the connection region 110.
In the display panel according to the first embodiment of the present invention, as shown in fig. 4, on the display panel 100, the longitudinal direction a of the protrusion 111 is set according to the longitudinal direction b of the connection region 110.
Specifically, the length direction a of the protrusion 111 is set according to the length direction b of the connection region 110, that is, the length direction a of the protrusion 111 is approximately parallel to the length direction b of the connection region 110, so that the included angle between the length direction a and the length direction b is within a preset angle.
Optionally, the preset angle is less than or equal to 30 degrees.
Further, optionally, the length direction a of the protrusion 111 is parallel to the length direction b of the connection region 110.
It can be understood that, a plurality of protrusions 111 are generally disposed on the connecting region 110, and when the plurality of protrusions 111 are disposed, the length direction a of each protrusion 111 is disposed according to the length direction b of the connecting region 110, that is, the included angle between the length direction a and the length direction b is within a preset angle.
Optionally, the included angle between the length direction a of each protrusion 111 and the length direction b of the connection region 110 is equal.
It is understood that the size of the protruding portion 111 disposed in the connecting region 110 cannot be arbitrarily set, and needs to satisfy the electrical connection performance between the display panel 100 and the FPC, for example, in the display panel of one of the current implementation structures, the size of the protruding portion 111 in the length direction is 400um, and the size in the width direction is 14 um.
Based on the setting requirement of the size of the protruding portion 111, when the extending direction of the protruding portion of the prior art is close to the extending direction perpendicular to the long side of the connection region as shown in fig. 3, the connection region of the display panel must be larger than the length of the protruding portion, and the width of the connection region cannot be further reduced, so that the frame size of the display panel is limited, and the narrower frame requirement cannot be further satisfied. In the embodiment of the present invention, since the length direction a of the protruding portion 111 is arranged along the length direction b of the connection region 110, even if the width of the connection region 110 is smaller than the length direction of the protruding portion 111, the arrangement of the protruding portion 111 is not affected, and thus the requirement of further narrowing the frame size of the display panel can be achieved.
In addition, as shown in fig. 6 and 7 and compared with fig. 2 and 3, the protrusion 111 on the display panel 100 is disposed according to the length direction b of the connection region 110 in the embodiment of the present invention, and compared with the prior art that the protrusion is disposed close to perpendicular to the extending direction of the long side of the connection region, the cumulative interval size between the protrusions 111 in the unit length along the length direction b of the connection region 110 is reduced, so that the effective initial contact area of the protrusion connected between the display panel and the FPC is increased when the pull-out force test of the FPC is performed, so as to ensure the pull-out force test requirement of the FPC.
Specifically, when an upward drawing force F as shown in fig. 6 is applied to the connection region 110, as compared with fig. 7, when the longitudinal direction a of the protrusion 111 is set in accordance with the longitudinal direction b of the connection region 110, the effective initial contact area between the display panel and the protrusion 111 on the FPC is the area indicated by the position c; when the protruding part is arranged in a manner of being approximately perpendicular to the extending direction of the long side of the connection region, the effective initial contact area between the display panel and the protruding part on the FPC is the area indicated by the position d. Obviously, the area indicated by the position c is much larger than that indicated by the position d, and therefore the effective initial contact area of the bump connected between the display panel and the FPC increases.
According to the display panel of the embodiment of the invention, the length direction of the protruding portion 111 is set according to the length direction of the connection region 110, so that the requirement of the pull-out force test of the FPC can be effectively ensured on the premise of meeting the requirement of the display panel on a further narrow frame.
In the embodiment of the present invention, as shown in fig. 4, a plurality of protrusion sets 120 are disposed on the connection region 110 along a length direction of the connection region 110, and each protrusion set 120 includes a plurality of protrusions 111 parallel to each other.

Note that, the first projection 1111 and the second projection 1112 are two adjacent projections in any projection set 120.
In the above manner, on the entire ground connection region 110, the plurality of protrusions 111 in each protrusion set 120 are sequentially arranged in a direction from the first edge 103 to the second edge 104 opposite to the first edge 103, and the plurality of protrusions 111 are sequentially offset along the predetermined direction, so that one end of each protrusion 111 extending along the predetermined direction is connected to a connection line on the display panel.
