The number for showing the connecting line being arranged in area, can save the space of the second non-display area.In addition, non-aobvious first in the embodiment
Show in area and the second non-display area and be provided with connecting line, the first non-display area and the second non-display area interior cabling number can be balanced
Mesh will not obviously increase the spacing distance between two through-holes, not influence visual effect, while will not obviously increase second
Through-hole is between viewing area at a distance from (i.e. the second non-display area) on direction, and the internal border for the display panel that is conducive to narrow increases
The light-emitting area of big viewing area, can be improved screen accounting, promotes the display effect of display panel.
In some alternative embodiments, display panel provided in an embodiment of the present invention can be all connections
Line is arranged between two adjacent through-holes and carries out cabling, i.e., is not provided with connecting line in the second non-display area, so as to
The maximized space for saving the second non-display area, no longer carries out attached drawing signal for this kind of embodiment.
In one embodiment, with continued reference to shown in Fig. 2, non-display area BA includes two the second non-display area BA2, two
The item number for the second connecting line M2 being respectively arranged in a second non-display area BA2 is equal.It first include being located in the embodiment
Part connecting line is arranged in cabling between two adjacent through-holes, can reduced by the first connecting line of the first non-display area
The number for the second connecting line being arranged in second non-display area, can save the space of the second non-display area, be conducive to narrow aobvious
Show the internal border of panel.In addition, the item number for the second connecting line being arranged in two the second non-display areas is equal, guarantee connection
The space that line occupies in two the second non-display areas is identical, can guarantee the in the same size of two the second non-display areas, then lead to
The equivalent width of the internal border of hole two sides is able to ascend the visual effect that display panel is shown.
In display panel provided by the invention, the first connecting line cabling between two adjacent through-holes connects for first
The setting of wiring can be there are many situation.For example, the first connecting line can be with the extension side of the first signal wire conventional in viewing area
To consistent or the first connecting line cabling can be carried out around the edge of through-hole in the first non-display area.When the first connecting line around
When through-hole edge carries out cabling, the total of the total length of the first first signal wire and conventional arrangement of first second signal wire may result in
Length generates difference, and then resistance has differences and causes to generate pressure drop difference when transmitting signal, eventually leads to the first first letter
The pixel that number line and the first second signal wire respectively drive, which is shown, to be had differences.Inventor has comprehensively considered above situation, by
Cabling between two adjacent through-holes is arranged in one connecting line, to reduce the basis that display panel internal border promotes screen accounting
On, further in display panel the first connecting line and its corresponding line width be designed.Following embodiments will be to specific feelings
Condition is illustrated.It should be noted that line width involved in following embodiments each means the width of line, i.e., in prolonging perpendicular to line
Stretch the width on direction.When line is curve, the calculating of line width can be calculated by unified computation rule, such as will be bent
After line amplifies certain multiple, curve levels off to straight line, measures line width of the width as virgin curve of the amplified straight line.
