This is explained in detail below.
请参阅图1-2,图1是本申请显示面板第一实施例的结构示意图,图2是图1所示的显示面板局部的结构示意图。Please refer to FIGS. 1-2, FIG. 1 is a schematic structural diagram of a first embodiment of a display panel of the present application, and FIG. 2 is a partial structural schematic diagram of the display panel shown in FIG.
在一实施例中,显示面板1作为诸如智能手机、平板电脑等电子设备的人机交互媒介,其外观上的新颖性是提高产品市场竞争力的重要手段,其中最典型的即为具有异形显示区域(常规的显示区域为矩形)的显示面板1。举例而言,显示面板1其显示区域的角落处不同于常规的直角,而是弧形角,并且其已然成为一种设计趋势。本实施例则以显示面板1其显示区域的角落处为弧形角为例进行阐述。In one embodiment, the display panel 1 serves as a human-computer interaction medium for electronic devices such as smart phones, tablet computers, etc. The novelty of its appearance is an important means to improve the market competitiveness of products, the most typical of which is a display with a special shape The display panel 1 of the area (the conventional display area is rectangular). For example, the corners of the display area of the display panel 1 are different from the conventional right angles, but arc angles, and it has become a design trend. In this embodiment, the corners of the display area of the display panel 1 are curved corners as an example for description.
显示面板1包括第一像素区11以及第二像素区12,第一像素区11与第二像素区12相邻。显示面板1上还包括多个像素13,该多个像素13沿行方向X和列方向Y以矩阵形式排布于显示面板1上。各像素13处于显示面板1的显示区域。由于显示面板1其显示区域的角落处为弧形角,为定义出显示区域的弧形角,显示面板1上对应位置的部分像素13缺省。而在显示面板1的显示区域上,存在像素13缺省的区域即为第二像素区12,不存在像素行131缺省的区域即为第一像素区11。第一像素区11与第二像素区12在显示面板1上表现为: 显示面板1的相对两端为第二像素区12,并且两端的第二像素区12所夹持的中间区域为第一像素区11。The display panel 1 includes a first pixel area 11 and a second pixel area 12. The first pixel area 11 is adjacent to the second pixel area 12. The display panel 1 further includes a plurality of pixels 13 arranged on the display panel 1 in a matrix along the row direction X and the column direction Y. Each pixel 13 is in the display area of the display panel 1. Since the corner of the display area of the display panel 1 is an arc-shaped angle, in order to define the arc-shaped angle of the display area, some pixels 13 at corresponding positions on the display panel 1 default. On the display area of the display panel 1, the default area where the pixel 13 exists is the second pixel area 12, and the default area where there is no pixel row 131 is the first pixel area 11. The first pixel area 11 and the second pixel area 12 appear on the display panel 1 as follows: the opposite ends of the display panel 1 are the second pixel areas 12, and the intermediate area sandwiched by the second pixel areas 12 on both ends is the first Pixel area 11.
请参阅图1、3。显示面板1还包括沿行方向X延伸的第一信号线14,以及沿列方向Y延伸的第二信号线15。沿行方向X延伸的第一信号线14与沿列方向Y延伸的第二信号线15在显示面板中分层设置,并且第一信号线14与第二信号线15在层叠方向上相互间隔开,二者之间间隔有层间绝缘层16使得交叠的信号线之间相互绝缘,进而使得交叠的信号线之间产生寄生电容。寄生电容为像素驱动电路负载中的一种,其会分担一部分的电压,造成压降,从而影响像素13的发光过程,在宏观上即为影响显示面板1的显示效果。Please refer to Figures 1 and 3. The display panel 1 further includes a first signal line 14 extending in the row direction X, and a second signal line 15 extending in the column direction Y. The first signal line 14 extending in the row direction X and the second signal line 15 extending in the column direction Y are layered in the display panel, and the first signal line 14 and the second signal line 15 are spaced apart from each other in the stacking direction An interlayer insulating layer 16 is spaced between the two to insulate the overlapping signal lines from each other, thereby causing parasitic capacitance between the overlapping signal lines. The parasitic capacitance is one of the load of the pixel driving circuit, which will share a part of the voltage and cause a voltage drop, thereby affecting the light-emitting process of the pixel 13, which affects the display effect of the display panel 1 macroscopically.
由于第二像素区12中部分像素13缺省,第二像素区12中的各行像素13所包含像素13的数量少于第一像素区11中的各行像素13,即第二像素区12中的各第一信号线14所对应的像素13数量少于第一像素区11中的各第一信号线14所对应的像素13数量,导致第二像素区12中各第一信号线14的负载与第一像素区11中各第一信号线14的负载存在差异,即第二像素区的负载小于第一像素区的负载,进而导致第一像素区11与第二像素区12显示不均,对显示面板1的显示效果造成不良影响。Since some pixels 13 in the second pixel area 12 default, each row of pixels 13 in the second pixel area 12 contains fewer pixels 13 than each row of pixels 13 in the first pixel area 11, that is, in the second pixel area 12 The number of pixels 13 corresponding to each first signal line 14 is less than the number of pixels 13 corresponding to each first signal line 14 in the first pixel area 11, resulting in the load and The load of each first signal line 14 in the first pixel area 11 is different, that is, the load of the second pixel area is smaller than that of the first pixel area, which in turn causes the first pixel area 11 and the second pixel area 12 to display unevenly. The display effect of the display panel 1 has an adverse effect.
在一实施例中,第二像素区12的第一信号线14与第二信号线15的交叠度大于或等于第一像素区11的第一信号线14与第二信号线15的交叠度,在一定程度上增加了第二像素区的寄生电容,即增加了第二像素区的负载,以减小第一像素区11与第二像素区12的第一信号线14负载的差异。In an embodiment, the overlapping degree of the first signal line 14 and the second signal line 15 of the second pixel area 12 is greater than or equal to the overlap of the first signal line 14 and the second signal line 15 of the first pixel area 11 The degree increases the parasitic capacitance of the second pixel area to a certain extent, that is, increases the load of the second pixel area, so as to reduce the difference in the load of the first signal line 14 between the first pixel area 11 and the second pixel area 12.
交叠度定义为像素区中第一信号线14与第二信号线15的总交叠面积占像素区面积的比例。The overlapping degree is defined as the ratio of the total overlapping area of the first signal line 14 and the second signal line 15 in the pixel area to the area of the pixel area.
第二像素区12沿行方向X划分有像素排布区121和非像素排布区122。其中,在第二像素区12的最外侧的像素行131、像素列132及对应延长线所定义的区域中,像素13所排布的区域为像素排布区121,而除像素排布区121之外的区域为非像素排布区122。第一信号线14沿行方向X贯穿像素排布区121和非像素排布区122;同理,第二信号线15沿列方向Y贯穿像素排布区121和非像素排布区122。因此,即便非像素排布区122未设置有像素13,非像素排布区122中同样设置有对应像素行131的第一信号线14以及对应像素列132的第二信号线15。The second pixel area 12 is divided into a pixel arrangement area 121 and a non-pixel arrangement area 122 along the row direction X. Among the areas defined by the outermost pixel row 131, pixel column 132, and corresponding extension line in the second pixel area 12, the area where the pixel 13 is arranged is the pixel arrangement area 121, and the pixel arrangement area 121 is excluded The area outside is the non-pixel arrangement area 122. The first signal line 14 penetrates the pixel arrangement area 121 and the non-pixel arrangement area 122 along the row direction X; similarly, the second signal line 15 penetrates the pixel arrangement area 121 and the non-pixel arrangement area 122 along the column direction Y. Therefore, even if the non-pixel arrangement area 122 is not provided with the pixels 13, the non-pixel arrangement area 122 is also provided with the first signal line 14 corresponding to the pixel row 131 and the second signal line 15 corresponding to the pixel column 132.
像素排布区121内的第一信号线14与第二信号线15的交叠度等于第一像 素区11内的第一信号线14与第二信号线15的交叠度。而非像素排布区122内的第一信号线14与第二信号线15的交叠度大于或等于第一像素区11内的第一信号线14与第二信号线15的交叠度。The overlapping degree of the first signal line 14 and the second signal line 15 in the pixel arrangement area 121 is equal to the overlapping degree of the first signal line 14 and the second signal line 15 in the first pixel area 11. The overlapping degree of the first signal line 14 and the second signal line 15 in the non-pixel arrangement area 122 is greater than or equal to the overlapping degree of the first signal line 14 and the second signal line 15 in the first pixel area 11.
其中,像素排布区121的叠层结构相同或相近,因此,在相同的单位面积内(如相同颜色的子像素区),像素排布区121与第一像素区11的第一信号线14负载一致,其对应第二像素区12的第一信号线14与第二信号线15的交叠度等于第一像素区11的第一信号线14与第二信号线15的交叠度的情况。The stacked structure of the pixel arrangement area 121 is the same or similar. Therefore, in the same unit area (such as sub-pixel areas of the same color), the pixel arrangement area 121 and the first signal line 14 of the first pixel area 11 The load is consistent, which corresponds to the case where the overlapping degree of the first signal line 14 and the second signal line 15 of the second pixel area 12 is equal to the overlapping degree of the first signal line 14 and the second signal line 15 of the first pixel area 11 .
非像素排布区122内的第一信号线14与第二信号线15的交叠度至少等于像素排布区121内的第一信号线14与第二信号线15的交叠度,即可平衡像素排布区121与非像素排布区122内第一信号线14与第二信号线15交叠所产生的寄生电容的差异,也就平衡了第二像素区12中第一信号线14的负载与第一像素区11中第一信号线14的负载,减小二者第一信号线14负载的差异,进而改善显示面板1的显示效果。The overlap degree of the first signal line 14 and the second signal line 15 in the non-pixel arrangement area 122 is at least equal to the overlap degree of the first signal line 14 and the second signal line 15 in the pixel arrangement area 121, The difference in the parasitic capacitance generated by the overlapping of the first signal line 14 and the second signal line 15 in the balanced pixel arrangement area 121 and the non-pixel arrangement area 122 balances the first signal line 14 in the second pixel area 12 And the load of the first signal line 14 in the first pixel area 11 reduce the difference in the load of the first signal line 14 between them, thereby improving the display effect of the display panel 1.
在替代实施例中,非像素排布区122内的第一信号线14与第二信号线15的交叠度大于像素排布区121内的第一信号线14与第二信号线15的交叠度。发明人发现,这样在非像素排布区122中,虽然未设置像素13会导致第一信号线14的负载小于第一像素区11以及像素排布区121中第一信号线14的负载,但仍然能实现平衡非像素排布区122与像素排布区121第一信号线14的负载,减小二者第一信号线14负载的差异,进一步改善显示面板1的显示效果。In an alternative embodiment, the overlapping degree of the first signal line 14 and the second signal line 15 in the non-pixel arrangement area 122 is greater than the intersection of the first signal line 14 and the second signal line 15 in the pixel arrangement area 121 Stacking. The inventor found that in the non-pixel arrangement area 122, although the pixel 13 is not provided, the load of the first signal line 14 is less than the load of the first signal line 14 in the first pixel area 11 and the pixel arrangement area 121, but It is still possible to balance the load of the first signal lines 14 in the non-pixel arrangement area 122 and the pixel arrangement area 121, reduce the difference in the load of the first signal lines 14 between them, and further improve the display effect of the display panel 1.
可见,当非像素排布区122内的第一信号线14与第二信号线15的交叠度等于像素排布区121内的第一信号线14与第二信号线15的交叠度时,第二像素区12的第一信号线14与第二信号线15的交叠度等于第一像素区11的第一信号线14与第二信号线15的交叠度。而当非像素排布区122内的第一信号线14与第二信号线15的交叠度大于像素排布区121内的第一信号线14与第二信号线15的交叠度时,第二像素区12的第一信号线14与第二信号线15的交叠度大于第一像素区11的第一信号线14与第二信号线15的交叠度。It can be seen that when the overlap degree of the first signal line 14 and the second signal line 15 in the non-pixel arrangement area 122 is equal to the overlap degree of the first signal line 14 and the second signal line 15 in the pixel arrangement area 121 The overlapping degree of the first signal line 14 and the second signal line 15 of the second pixel area 12 is equal to the overlapping degree of the first signal line 14 and the second signal line 15 of the first pixel area 11. When the overlap degree of the first signal line 14 and the second signal line 15 in the non-pixel arrangement area 122 is greater than the overlap degree of the first signal line 14 and the second signal line 15 in the pixel arrangement area 121, The overlapping degree of the first signal line 14 and the second signal line 15 of the second pixel area 12 is greater than the overlapping degree of the first signal line 14 and the second signal line 15 of the first pixel area 11.
以下详细阐述第一信号线与第二信号线的布线设计。The wiring design of the first signal line and the second signal line is explained in detail below.
在一实施例中,第二信号线包括数据信号线和电源信号线。第一信号线包括第一扫描信号线、第二扫描信号线以及发射信号线。每行像素对应一条第一扫描信号线以及一条第二扫描信号线,第一扫描信号线用于控制像素,以允许数据信号线上的数据信号写入像素,第二扫描信号线用于控制像素的电压复位。 每行像素对应一条发射信号线,发射信号线用于控制像素,以与数据信号线共同驱动电源信号线上的电源信号写入像素。In an embodiment, the second signal line includes a data signal line and a power signal line. The first signal line includes a first scan signal line, a second scan signal line, and an emission signal line. Each row of pixels corresponds to a first scan signal line and a second scan signal line. The first scan signal line is used to control the pixel to allow data signals on the data signal line to be written into the pixel, and the second scan signal line is used to control the pixel Voltage reset. Each row of pixels corresponds to an emission signal line, and the emission signal line is used to control the pixel to drive the power signal on the power signal line to be written into the pixel together with the data signal line.

Among them, one scanning circuit corresponds to one SCAN1 & 3 signal line and one SCAN2 signal line, and one transmitting circuit can correspond to a number of EM signal lines.
请参阅图4,图4是本申请显示面板第二实施例的结构示意图。Please refer to FIG. 4, which is a schematic structural diagram of a second embodiment of a display panel of the present application.
在一实施例中,非像素排布区21内的第一信号线22、数据信号线23和电源信号线24中的至少一者的线宽大于像素排布区25的第一信号线22、数据信号线23和电源信号线24的对应线宽,以使得非像素排布区21内的第一信号线22与数据信号线23、电源信号线24的交叠度大于或等于像素排布区25内的第一信号线22与数据信号线23、电源信号线24的交叠度。In an embodiment, at least one of the first signal line 22, the data signal line 23, and the power signal line 24 in the non-pixel arrangement area 21 has a line width greater than that of the first signal line 22 in the pixel arrangement area 25, The corresponding line widths of the data signal line 23 and the power signal line 24 are such that the overlapping degree of the first signal line 22 and the data signal line 23 and the power signal line 24 in the non-pixel arrangement area 21 is greater than or equal to the pixel arrangement area The overlapping degree of the first signal line 22, the data signal line 23, and the power signal line 24 in 25.
由于像素排布区25与非像素排布区21内的数据信号线23、电源信号线24的线宽通常保持一致。因此本实施例通过增大非像素排布区21内的第一信号线22的线宽,以减小非像素排布区21与像素排布区25第一信号线22的负载差异。The pixel signal area 25 and the non-pixel signal area 21 generally have the same width of the data signal line 23 and the power signal line 24. Therefore, in this embodiment, the line width of the first signal line 22 in the non-pixel arrangement area 21 is increased to reduce the load difference between the non-pixel arrangement area 21 and the pixel arrangement area 25 of the first signal line 22.

同理,非像素排布区21内的发射信号总线224的线宽大于像素排布区25内发射信号线225的线宽,其中发射信号总线224的线宽B优选为参与并线的发射信号线225线宽b的总和(例如两条发射信号线225参与并线,则发射信号总线224的线宽B等于该两条发射信号线225线宽b的和),以使非像素排布区21内的发射信号总线224与数据信号线23、电源信号线24的交叠度等于像素排布区25内的对应发射信号线225与数据信号线23、电源信号线24的交叠度。Similarly, the line width of the transmission signal bus 224 in the non-pixel arrangement area 21 is larger than the line width of the transmission signal line 225 in the pixel arrangement area 25, wherein the line width B of the transmission signal bus 224 is preferably the transmission signal participating in the parallel The sum of the line width 225 b (for example, if two transmission signal lines 225 participate in the parallel connection, the line width B of the transmission signal bus 224 is equal to the sum of the line width b of the two transmission signal lines 225), so that the non-pixel arrangement area The overlapping degree of the transmission signal bus 224 and the data signal line 23 and the power signal line 24 in 21 is equal to the overlapping degree of the corresponding transmission signal line 225 and the data signal line 23 and the power signal line 24 in the pixel arrangement area 25.
进一步地,可通过进一步增大非像素排布区21内的扫描信号总线221、发射信号总线224的整体线宽,进一步平衡非像素排布区21与像素排布区25第一信号线22的负载。对应地,扫描信号总线221的线宽大于参与并线的第一扫 描信号线222与第二扫描信号线223线宽的总和,发射信号总线224的线宽大于参与并线的发射信号线225线宽的总和。Further, the overall signal width of the scan signal bus 221 and the emission signal bus 224 in the non-pixel arrangement area 21 can be further increased to further balance the first signal line 22 between the non-pixel arrangement area 21 and the pixel arrangement area 25 load. Correspondingly, the line width of the scan signal bus 221 is greater than the sum of the line widths of the first scan signal line 222 and the second scan signal line 223 participating in the merge, and the line width of the transmit signal bus 224 is greater than the line 225 of the transmit signal line participating in the merge The wide sum.
