Detailed Description
At present, in a full-face screen, since the driving signal lines around the excavated area need to be routed around the excavated area, as shown in fig. 1, the distance between the driving signal lines around the excavated area becomes smaller, thereby increasing the parasitic capacitance and the load capacity of the driving signal lines. In addition, in order to implement the narrow frame design of the excavated area, the driving signal lines around the excavated area are stacked by using multiple layers of routing lines, which also increases the parasitic capacitance and the loading capacity of the driving signal lines. Finally, the load capacity of the driving signal lines around the hole digging area is larger than that of the driving signal lines in other areas, so that the problem of split display occurs when the gray scale display and the heavy-load picture are displayed.
The embodiment of the invention provides a display panel and a display device, aiming at the problem that display split screen occurs in a hole digging area in the prior art. In order to make the objects, technical solutions and advantages of the present invention clearer, specific embodiments of a display panel and a display device according to an embodiment of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments described below are only for illustrating and explaining the present invention and are not to be used for limiting the present invention. And the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The shapes and sizes of the various elements in the drawings are not to scale and are merely intended to illustrate the invention.
A display panel provided in an embodiment of the present invention, as shown in fig. 2, includes a display area a, a first non-display area B surrounding the display area a, and at least one second non-display area C; the display area a includes a plurality of driving signal lines 100 extending along a first direction X and arranged in a second direction Y, the first direction X intersecting the second direction Y; the display area a is divided into a first display area a1 and a second display area a2, the first display area a1 surrounds the second non-display area C, and the length of the driving signal line 100 positioned in the first display area a1 is greater than the length of the driving signal line 100 positioned in the second display area a2, only a part of the driving signal line 100 in the first display area a1 and the second display area a2 is illustrated in fig. 2;
the first non-display area B includes a first fan-out area B1 and a second fan-out area B2, as shown in fig. 4 to 7, the first fan-out area B1 includes a plurality of first fan-out traces 210 and second fan-out traces 220, and the first fan-out traces 210 and the second fan-out traces 220 are electrically connected to the driving signal lines 100 in the first display area a 1; as shown in fig. 3, the second fan-out region B2 includes a plurality of third fan-out traces 310 and fourth fan-out traces 320, and the third fan-out traces 310 and the fourth fan-out traces 320 are electrically connected to the driving signal lines 100 in the second display area a 2; wherein, the overlapping area between the at least one first fan-out trace 210 and the second fan-out trace 220 is smaller than the overlapping area between the third fan-out trace 310 and the fourth fan-out trace 320.
Specifically, in the display panel provided in the embodiment of the present invention, the second non-display area C is not displayed as a hole digging area, and the second non-display area C may be a blind hole, that is, a non-blocking pattern, but a transparent medium, such as a substrate, exists, or may be a real hole digging, that is, a film material is completely dug away, which is not limited herein. The second non-display area C may be disposed at any position in the display area a of the display panel, and is preferably disposed at an upper middle position of the display area a.
Specifically, in the above display panel provided in the embodiment of the present invention, the first fan-out trace 210 and the second fan-out trace 220 are used to electrically connect the driving signal line 100 in the first display area a1 to the IC chip, and the first fan-out trace 210 and the second fan-out trace 220 are electrically connected to different driving signal lines 100; the third and fourth fan- out traces 310 and 320 are used to electrically connect the driving signal lines 100 within the second display area a2 to the IC chip, and the third and fourth fan- out traces 310 and 320 electrically connect different driving signal lines 100. By setting the overlapping area between at least one first fan-out wire 210 and at least one second fan-out wire 220 to be smaller than the overlapping area between the third fan-out wire 310 and the fourth fan-out wire 320, the parasitic capacitance of the first fan-out wire 210 and the second fan-out wire 220 is reduced to reduce the load capacity, so that the load capacity part of the driving signal line 100 in the first display area A1 higher than the driving signal line 100 in the second display area A2 is compensated, the difference of the driving signal line 100 in the first display area A1 and the driving signal line 100 in the second display area A2 in the load capacity is integrally improved, and the problem of split display during gray scale display and heavy load pictures is solved.
Optionally, in the display panel provided in the embodiment of the present invention, a sum of a parasitic capacitance of the driving signal line 100 located in the first display area a1 and a parasitic capacitance of the electrically connected first fan-out trace 210 (or the electrically connected second fan-out trace 220) is a first capacitance sum;
the sum of the parasitic capacitance of the driving signal line 100 located in the second display area a2 and the parasitic capacitance of the electrically connected third fan-out trace 310 (or fourth fan-out trace 320) is a second capacitance sum;
the parasitic capacitance of the first fan-out trace 210 (or the second fan-out trace 220) in the first fan-out region B1 can be adjusted to ensure that the first capacitance sum is substantially the same as the second capacitance sum, so as to eliminate the problem of split display in gray scale display and heavy loading of the picture as much as possible.
Optionally, in the display panel provided in the embodiment of the present invention, as shown in fig. 4 to fig. 6, orthographic projections of the first fan-out trace 210 and the second fan-out trace 220 in the same plane may be arranged at intervals. Alternatively, m first fan-out lines 210 may be repeatedly arranged and then arranged at intervals with n second fan-out lines 220 repeatedly arranged, m and n may be the same, for example, 2, 3, 4 … …, etc., and m and n may also be different, which is not limited herein. For example, as shown in fig. 7, three first fan-out traces 210 are arranged repeatedly, i.e., adjacently, and then spaced apart from three adjacently arranged second fan-out traces 220.
Specifically, the size of the overlapping area between the first fan-out trace 210 and the second fan-out trace 220 determines the size of the parasitic capacitance and the size of the load capacity of the first fan-out trace 210 and the second fan-out trace 220, and the size of the overlapping area between the third fan-out trace 310 and the fourth fan-out trace 320 determines the size of the parasitic capacitance and the size of the load capacity of the third fan-out trace 310 and the fourth fan-out trace 320. Therefore, by adjusting the overlapping area between the first fan-out trace 210 and the second fan-out trace 220 to be smaller than the overlapping area between the third fan-out trace 310 and the fourth fan-out trace 320, the parasitic capacitance and the load capacity of the first fan-out trace 210 and the second fan-out trace 220 can be reduced, so as to improve the difference in the load capacity between the driving signal line 100 in the first display area a1 and the driving signal line 100 in the second display area a2, and alleviate the problem of split display during gray scale display and heavy loading of pictures.
Specifically, since the overlapping area between the third fan-out trace 310 and the fourth fan-out trace 320 is larger than the overlapping area between the first fan-out trace 210 and the second fan-out trace 220, an overlapping must exist between the third fan-out trace 310 and the fourth fan-out trace 320, that is, the problem that a short circuit does not occur between the third fan-out trace 310 and the fourth fan-out trace 320 is solved, the third fan-out trace 310 and the fourth fan-out trace 320 need to be located in at least two metal film layers, and the third fan-out trace 310 and the fourth fan-out trace 320 which are overlapped are located in different metal film layers. As shown in fig. 3, each third fan-out trace 310 may be located on the first metal film layer 400; each fourth fan-out trace 320 is located on the second metal film layer 500, and the overlapping area between each third fan-out trace 310 and the fourth fan-out trace 320 should be the same as much as possible.
Optionally, in order to reduce the parasitic capacitance between the third fan-out trace 310 and the fourth fan-out trace 320 as much as possible, as shown in fig. 3, the third fan-out trace 310 and the fourth fan-out trace 320 are generally arranged in the first metal film layer 400 and the second metal film layer 500 at intervals, that is, the forward projections of the third fan-out trace 310 and the fourth fan-out trace 320 in the same plane are arranged at intervals. In order to reduce the area occupied by the third fan-out trace 310 and the fourth fan-out trace 320 as much as possible and to improve the space utilization rate, the third fan-out trace 310 and the fourth fan-out trace 320 located in the first metal film layer 400 and the second metal film layer 500 are generally aligned, that is, theoretically, the overlapping area between the adjacent third fan-out trace 310 and the fourth fan-out trace 320 is the largest, but complete alignment cannot be guaranteed due to problems such as alignment error during manufacturing, and therefore, a situation of partial overlapping between the third fan-out trace 310 and the fourth fan-out trace 320 may occur in an actually manufactured pattern film layer.
Optionally, in the display panel provided in the embodiment of the present invention, as shown in fig. 4 and 5, the first fan-out trace 210 and the second fan-out trace 220 may not overlap with each other.
Specifically, the overlapping area between the first fan-out trace 210 and the second fan-out trace 220 is zero, and the parasitic capacitance of the first fan-out trace 210 can be minimized to maximize the load difference with the fan-out trace in the second fan-out area B2. In addition, the parasitic capacitance and the loading capacity of the first fan-out trace 210 and the second fan-out trace 220 can be further adjusted by adjusting the distance between the first fan-out trace 210 and the second fan-out trace 220.
Optionally, in the display panel provided in the embodiment of the present invention, as shown in fig. 4, the first fan-out trace 210 and the second fan-out trace 220 may be both located on the first metal film layer.
Specifically, a single-layer metal design is adopted in the first fan-out region B1, and by adjusting the distance between the adjacent first fan-out trace 210 and the second fan-out trace 220, the parasitic capacitance and the loading capacity of the first fan-out trace 210 and the second fan-out trace 220 can be adjusted. The patterns of the first fan-out wiring 210 and the second fan-out wiring 220 are arranged in the same film layer, so that pattern design is facilitated, and problems such as alignment errors and the like during manufacturing of multiple film layers can be avoided.
Optionally, in the above display panel provided in the embodiment of the present invention, as shown in fig. 5, the first fan-out trace 210 and the second fan-out trace 220 may also be located in at least two metal film layers, that is, the first fan-out region B1 adopts a multi-layer metal design.
Specifically, the number of metal film layers of the first fan-out region B1 can be matched with the number of metal film layers of the second fan-out region B2, so as to improve the utilization rate of the metal film layers. For example, the second fan-out region B2 has two metal film layers, and the first fan-out region B1 may also have the same two metal film layers. For another example, the second fan-out region B2 is located in three metal film layers, and the first fan-out region B1 may also be located in two metal film layers, which is not limited herein.
Optionally, in the display panel provided in the embodiment of the present invention, as shown in fig. 5, the first fan-out trace 210 may be located on the first metal film layer 400, and the second fan-out trace 220 may be located on the second metal film layer 500.
Specifically, the first fan-out trace 210 and the second fan-out trace 220 may be spaced apart at the first metal film layer 400 and the second metal film layer 500.
Optionally, in the display panel provided in the embodiment of the present invention, at least one first fan-out trace 210 and one second fan-out trace 220 may also overlap with each other. For example, as shown in fig. 6, the first fan-out trace 210 may be located on the first metal film layer 400, the second fan-out trace 220 may be located on the second metal film layer 500, and the overlapping area between the first fan-out trace 210 and the second fan-out trace 220 is substantially the same, i.e., the first fan-out region B1 adopts a dual-layer metal trace design.
Specifically, by adjusting the size of the overlapping area between the first fan-out trace 210 and the second fan-out trace 220, the size of the parasitic capacitance and the load capacity of the first fan-out trace 210 and the second fan-out trace 220 can be controlled, so that the difference between the parasitic capacitance and the load capacity of the first fan-out trace 210 and the second fan-out trace 220 compensates the load capacity difference between the electrically connected driving signal lines 100, thereby alleviating the problem of split display occurring during gray scale display and heavy load of pictures.
Optionally, in the display panel provided in the embodiment of the present invention, the driving signal line 100 may be a data signal line, that is, the first fan-out trace 210, the second fan-out trace 220, the third fan-out trace 310, and the fourth fan-out trace 320 are all electrically connected to the data signal line in a one-to-one correspondence manner.
Specifically, the relationship among the parasitic capacitance C1 of the data signal line located in the first display area a1, the parasitic capacitance C2 of the first fan-out trace 210 (the second fan-out trace 220) of the first fan-out area B1, the parasitic capacitance C3 of the data signal line located in the second display area a2, and the parasitic capacitance C4 of the third fan-out trace 310 (the fourth fan-out trace 320) of the second fan-out area B2 is known through simulation model calculation. Table 1 lists the four parasitic capacitance relationships when the parasitic capacitances of the first fan-out trace 210 and the third fan-out trace 310 are the same in the prior art, the four parasitic capacitance relationships when the first fan-out trace 210 and the second fan-out trace 220 adopt a single-layer metal design in embodiment 1 of the present invention, and the four parasitic capacitance relationships when the first fan-out trace 210 and the second fan-out trace 220 adopt a double-layer metal design in embodiment 2 of the present invention. As can be seen by comparing the prior art, changing the overlapping area of the first fan-out trace 210 and the second fan-out trace 220 can improve the overall difference in parasitic capacitance.
