The shape of the irregular non-display portion 720 is not particularly limited. The special-shaped display part 710 and the special-shaped non-display part 720 are disposed in two continuous regions. For example, the special-shaped non-display portion 720 may be disposed in a left side region of the display panel 10. Or the special shaped non-display portion 720 may be disposed at a right side area of the display panel 10. The shape and size of the display panel 10 may be set arbitrarily as long as the manufacturing process can be implemented. The non-contoured region 800 may include a non-contoured display portion 810 and a bottom bezel portion 820.

In this embodiment, the display panel 10 may be a liquid crystal display panel or an electroluminescent display panel, or another type of display panel. When the materials of the display panels are different, the specific structure of the pixel unit 102 may be different. The traces on the display panel 10 can be arranged according to the idea in this application.
In one embodiment, referring again to fig. 1, the display panel 10 includes M first pixel cell rows 110. The first pixel unit row 110 is disposed on the substrate 101. The first pixel cell row 110 extends along a first direction. Each of the first pixel cell rows 110 includes N pixel cells 102.

The display panel 10 further includes a plurality of second scan lines 220. The second scan line 220 is disposed on the substrate 101. The second scan line 220 extends along the second direction. Each of the second scan lines 220 is electrically connected to a plurality of the pixel units 102 in at least two of the first pixel unit columns 120 disposed adjacent to or spaced apart from each other. The number of the pixel units 102 electrically connected to the second scan line 220 may be equal to the number of the pixel units 102 electrically connected to the first scan line 210. The number of the pixel units 102 electrically connected to the second scan line 220 may also be less than the number of the pixel units 102 electrically connected to the first scan line 210, so as to ensure that the display panel 10 does not have display problems such as split display. For example, the display panel 10 further includes 4 second scan lines 220. Each of the second scan lines 220 is electrically connected to 6 of the pixel units 102. The number of the pixel units 102 electrically connected to each of the first scan lines 210 in the plurality of first scan lines 210 shown in fig. 3 is the same. The number of the pixel units 102 electrically connected to each of the second scan lines 220 in the plurality of second scan lines 220 shown in fig. 3 is the same. For another example, the display panel 10 further includes 2 second scan lines 220. Each of the second scan lines 220 is electrically connected to all of the pixel units 102 in 4 of the first pixel unit columns 120. Each of the second scan lines 220 is electrically connected to 12 of the pixel units 102. N-2N, N-3N, or other relationships may be set, so that the number of the pixel units 102 electrically connected to each of the first scan lines 210 is the same as the number of the pixel units 102 electrically connected to each of the second scan lines 220, or is within an error tolerance.
In this embodiment, the display panel 10 includes a substrate 101 and a plurality of pixel units 102. The display panel 10 further includes a plurality of first pixel unit rows 110, a plurality of first pixel unit columns 120, a plurality of first scan lines 210, and a plurality of second scan lines 220. The display panel 10 includes an shaped area 700 and a non-shaped area 800. The shaped area 700 comprises a shaped display 710 and a shaped non-display 720. The shaped display 710 and the shaped non-display 720 are complementarily arranged with respect to the shaped area 700. A plurality of the first pixel unit rows 110 are disposed in the non-irregular area 800. The plurality of first pixel unit columns 120 are disposed on the irregular shaped display portion 710. Each of the first scan lines 210 is electrically connected to N pixel units 102 in one of the first pixel unit rows 110. Each of the second scan lines 220 is electrically connected to a plurality of the pixel cells 102 in at least two of the first pixel cell columns 120 disposed adjacent to or spaced apart from each other. The first scan line 210 is disposed in the non-irregular area 800 and electrically connects the first pixel unit rows 110 arranged in rows. The second scan line 220 is disposed on the non-irregular display portion 710 and electrically connects the first pixel unit columns 120 arranged in columns. The partitioned arrangement of the first scan lines 210 and the second scan lines 220 enables the pixel units 102 in the display panel 10 to be uniformly wired, and avoids stacking of scan lines.
In one embodiment, when the number of the pixel units 102 electrically connected to the first scan lines 210 and the second scan lines 220 is the same, the display panel 10 does not need to perform load compensation. When the display panel 10 does not need load compensation, the area of the compensation unit arranged on the display panel 10 is saved, so that the screen occupation ratio of the display panel 10 is larger.
In one embodiment, the second scan line 220 may be electrically connected to 3 of the first pixel unit columns 120. At this time, the number of the pixel units 102 electrically connected to each of the second scan lines 220 is the same as the number of the pixel units 102 electrically connected to each of the first scan lines 210. In this embodiment, the loading amounts of the first scan line 210 and the second scan line 220 may be the same or the loading amount difference between every two scan lines is within an error allowable range, the display uniformity of the display panel 10 is better, and the phenomenon of split display does not occur.
In one embodiment, the display panel 10 further includes a first scan driving circuit 410 and a second scan driving circuit 420. The first scan driving circuit 410 is disposed on the substrate 101. The first scan driving circuit 410 is electrically connected to the plurality of first scan lines 210, respectively.
The second scan driving circuit 420 is disposed on the substrate 101. The second scan driving circuit 420 is electrically connected to the second scan lines 220. The positions of the first scan driving circuit 410 and the second scan driving circuit 420 are not particularly limited. The scan driving circuit may be disposed close to the corresponding scan line. For example, the first scan driving circuit 410 may be disposed in the frame regions on the left and right sides of the display panel 10. The second scan driving circuit 420 may be disposed in upper and lower frame regions of the display panel 10.
The first scan driving circuit 410 and the second scan driving circuit 420 may drive each of the pixel units 102 connected thereto, respectively. Each pixel unit 102 on the display panel 10 can be connected in a row direction or a column direction through the first scan line 210 or the second scan line 220. The second scan line 220 connects all the pixel units 102 in two adjacent or interlaced first pixel unit columns 120.
Specifically, the first scan driving circuit 410 is used to drive the first scan lines 210 respectively. The second scan driving circuit 420 is used to drive the second scan lines 220. In use, the magnitude and intensity of the output driving signals of the first scan driving circuit 410 and the second scan driving circuit 420 may be set respectively. The driving signals are loaded on the first scanning line 210 and the second scanning line 220, so that the signal delay reaching each pixel unit column is the same, and the display uniformity of the display panel 10 can be improved. All the pixel units 102 on the display panel 10 can be uniformly lighted, and the display panel 10 is prevented from displaying the split screen phenomenon in the irregular area 700 and the non-irregular area 800.
It will be appreciated that in one embodiment, additional scan lines may need to be provided. Then, the other scan lines also need to be arranged in the row direction of the pixel units 102. For example, a gate Scan line (Scan) and a light emission control line (Emit) may be provided in one embodiment. Both the gate scanning lines and the light emission control lines are arranged in the row direction of the pixel units 102. The gate scan lines and the light emission control lines may cooperate to control the pixel unit 102 to perform display.
