However, the total number of the first auxiliary lines AL1 or the number of the first auxiliary lines AL1 electrically connected to each of the first scan lines GL1 can be changed according to actual needs.

A plurality of second auxiliary lines AL2 are respectively located between two adjacent first rows R1. Further, the plurality of second auxiliary lines AL2 are located in an array formed by a plurality of sub-pixels SP arranged, wherein the plurality of second auxiliary lines AL2 can be arranged along the second direction D2 only on two adjacent first Between rows R1 (two adjacent first rows R1 are referred to as a set of first rows R1 ), or a plurality of second auxiliary lines AL2 may be respectively located between a plurality of sets of first rows R1 . For example, the plurality of second auxiliary lines AL2 may be arranged in a staggered arrangement (as shown in FIG. 1 ). The staggered arrangement means that the plurality of second auxiliary lines AL2 can be distributed in an irregular manner in an array formed by a plurality of sub-pixels SP, instead of being regularly distributed in an array formed by a plurality of sub-pixels SP. Through the design of the dislocation arrangement, the moire pattern phenomenon caused by the periodic structure can be avoided, and the perception of gray scale variation by the human eye can be reduced.

Each second auxiliary line AL2 extends from a corresponding first scan line GL1 to an adjacent second scan line GL2 along the second direction D2, and each second scan line GL2 is connected to the adjacent second scan line GL2 through at least one second auxiliary line AL2. A corresponding first scan line GL1 is electrically connected. For example, a plurality of second auxiliary lines AL2, a plurality of first scan lines GL1 and a plurality of second scan lines GL2 may belong to the same conductive layer, and each second auxiliary line AL2 is in contact with one electrically connected first scan line GL1 and one electrically connected second scan line GL2.

In other embodiments, each second scan line GL2 can be electrically connected to the corresponding first scan line through a plurality of second auxiliary lines AL2. By increasing the number of the second auxiliary lines AL2 electrically connecting each of the first scan lines GL1 and the corresponding second scan lines GL2, it is helpful to reduce the impedance and improve the uniformity of the display screen. However, the total number of the second auxiliary lines AL2 or the number of the second auxiliary lines AL2 electrically connecting each of the first scan lines GL1 and the corresponding second scan lines GL2 can be changed according to actual needs.

Each first scan line GL1 is electrically connected to the corresponding second scan line GL2 by the second auxiliary line AL2, so that the two adjacent second rows R2 can receive scan signals at the same timing, and then match the first data line The signal input of DL1 and the second data line DL2 can realize two data lines and half gate lines. line, 2DHG) drive mode. Specifically, scan signals are input to the first scan lines GL1 through the first portions P1 of the first auxiliary lines AL1 at different timings, for example. In each timing sequence, the scan signal transmitted to the first scan line GL1 is transmitted to the corresponding second scan line GL2 via the second auxiliary line AL2, so that the plurality of sub-pixels SP in the two adjacent second rows R2 are The active element SP1 is turned on at the same timing.

A first scan line GL1 and a second scan line GL2 electrically connected are respectively located on opposite sides of one of the two adjacent second rows R2, and a second scan line GL2 is located in the two adjacent second rows R2. between row R2. Since the first scan line GL1 is located on one side of the electrically connected two adjacent second rows R2 (such as the gate signal end side) rather than between the electrically connected two adjacent second rows R2, Therefore, the influence of the coupling effect of the first scan line GL1 (or the second scan line GL2 ) and the first part P1 (or the second auxiliary line AL2 ) of the first auxiliary line AL1 in the two adjacent second rows R2 can be reduced The number of sub-pixels SP. Since the two sub-pixels SP located on the adjacent two sides of the second auxiliary line AL2 in the first direction D1 (see the circled area by the dotted line) may be affected by the coupling effect, each second auxiliary line AL2 can be set Between adjacent red sub-pixels R and blue sub-pixels B, in order to avoid the coupling effect from affecting the green sub-pixels, which are easier for human eyes to perceive gray-scale variation.

Specifically, the second scan line GL2 can be electrically connected to the corresponding first scan line GL1 through the second auxiliary line AL2. Therefore, the first portion P1 of the first auxiliary line AL1 electrically connected to the first scan line GL1 can be electrically connected without conducting conduction. The through hole is electrically connected to the second scan line GL2, and the first portion P1 of the first auxiliary line AL1 electrically connected to the first scan line GL1 also does not need to extend above the electrically connected second scan line GL2, so as to minimize the The number of sub-pixels SP affected by the coupling effect of the first portion P1 and the first scan line GL1 (or the second scan line GL2 ). In addition, compared to the second scan line GL2 that also receives scan signals synchronously with the first scan line GL1 through the first portion P1 and the conductive via, the first scan line GL1 and the second scan line are realized by the second auxiliary line AL2 In addition to reducing the influence of the coupling effect, the GL2 can receive the scanning signal synchronously, and the position of the second auxiliary line AL2 can be designed (for example, set between the red sub-pixel R and the blue sub-pixel B) to improve the picture performance. .

The distance between each of the second auxiliary lines AL2 and the electrically connected first auxiliary line AL1 may be determined according to actual design requirements (such as the size, resolution, line impedance, etc. of the display panel 1 ).

Two data lines DL2 are formed together. The conductive layer may be a metal layer. The metal layer may be a single metal layer or a stacked layer of multiple metal layers.

Referring to FIG. 2 , the main difference between the display panel 1A and the display panel 1 of FIG. 1 is that the display panel 1A further includes a plurality of third auxiliary lines AL3 . The plurality of third auxiliary lines AL3 are disposed near the ends of the plurality of first scan lines GL1 and the plurality of second scan lines GL2.
