It should be noted that the embodiment shown in fig. 2 only schematically shows a relative position relationship diagram of the display area 10, the non-display area 20 and the first and second directions, and does not represent actual dimensions. Fig. 3 shows only a relative positional relationship diagram of the sub-pixels in the first display area, and does not represent an actual size. Fig. 2 only shows a schematic diagram of the second display area 20 at least partially surrounding the first display area 10, and in some other embodiments of the present application, the position relationship between the first display area 10 and the second display area 20 may be other, which is not specifically limited in the present application. In addition, fig. 3 shows relative positional relationships among the first display region 10, the first pixel row 11, the first color sub-pixel 13, the second color sub-pixel 14, the third color sub-pixel 15, the second pixel row 12, and the white sub-pixel 17, and does not represent an actual size. Fig. 3 shows only one arrangement of the first color sub-pixel 13, the second color sub-pixel 14, and the third color sub-pixel 15 that are alternately arranged, and the specific arrangement is not limited. The number of the white sub-pixels 17 in the second pixel row shown in fig. 3 is not limited, and the number of the white sub-pixels 17 may be made according to actual conditions. Further optionally, the first direction is perpendicular to the second direction in one plane.
Specifically, as shown in fig. 2-fig. 3, the shape and area of the first color sub-pixel 13, the second color sub-pixel 14, and the third color sub-pixel 14 included in the first pixel row 11 of the first display area 10 may be designed to be the same, or may be different, and may be adjusted according to actual needs, the second pixel row 12 further includes a white sub-pixel 17, wherein the first pixel row 11 and the second pixel row 12 are located in different rows adjacent to each other along the second direction, the first color sub-pixel 13 in the first pixel row 11 corresponds to the white sub-pixel 17 in the second pixel row 12, similarly, the second color sub-pixel 14 in the first pixel row 11 corresponds to the white sub-pixel 17 in the second pixel row 12, the third color sub-pixel 15 in the first pixel row 11 corresponds to the white sub-pixel 17 in the second pixel row 12, and in the second direction, the width of the first color sub-pixel 13 is equal to the width of the corresponding white sub-pixel 17, similarly, the width of the second color sub-pixel 14 is equal to the width of the corresponding white sub-pixel 17, and the width of the third color sub-pixel 15 is equal to the width of the corresponding white sub-pixel 17, as shown in fig. 3.
In addition, the width of each sub-pixel in the first pixel row 11 may also be greater than the width of the white sub-pixel 17 in the second pixel row 12, such a configuration structure enables enough space between two adjacent white sub-pixels 17 in the second pixel row 12 to be able to route signal traces, because the width of each sub-pixel in the first pixel row 11 is greater than or equal to the width of the white sub-pixel 17 in the second pixel row 12, the signal traces between two adjacent sub-pixels in the first pixel row 11 may extend from the first pixel row 11 to the second pixel row 12, so that the signal traces are linear traces in the first display area 10, no wire winding is needed, the situation that the signal traces bypass the white sub-pixel 17 with a larger area as shown in fig. 1 is avoided, the situation that the signal is concentrated and stacked to cause the signal coupling phenomenon between the traces, wherein the signal traces are located between the sub-pixels arranged along the first direction, and extends in a second direction.
Further, since the light transmittance of the white sub-pixel 17 is higher than the light transmittance of the first color sub-pixel 13, the second color sub-pixel 14 and the third color sub-pixel 15, the white sub-pixel 17 disposed in the first display region 10 can effectively adjust the brightness of the first display region 10, and reduce the brightness difference between the first display region 10 and the second display region 20.
According to the display panel provided by the application, because the width of each sub-pixel in the first pixel row 11 is greater than or equal to the width of the white sub-pixel 17 in the second pixel row 12, the straightened signal routing can be arranged between the sub-pixels arranged along the first direction, the signal routing does not need to be wound, the signal routing is sparse, and the signal coupling between the signal routing is reduced. In addition, the white sub-pixel 17 is arranged in the first display area 10, so that the pixel structures of the first display area 10 and the second display area 20 are different, when the first display area 10 is used for normal display, the first display area 10 plays a display function, and when a camera is arranged in an area corresponding to the first display area 10, a better shooting effect can be achieved by the high light transmittance of the first display area 10 in a shooting stage. In addition, each sub-pixel of the display panel is arranged in a periodic mode, on one hand, the manufacturing process can be simplified, and on the other hand, the display panel has a good effect on the uniformity of light.
Optionally, with continued reference to fig. 3, the area of each sub-pixel in the first pixel row 11 is S1, and the area of each white sub-pixel 17 in the second pixel row 12 is S2，S2＞S1。
Specifically, since the white sub-pixels 17 have a higher light transmittance with respect to the sub-pixels in the first pixel row 11, and the area of the white sub-pixels 17 in the second pixel row 12 is larger than that of the sub-pixels in the first pixel row 11, such a structure can further improve the light transmittance of the first display area 10 while ensuring the display effect of the first display area 10, and further improve the imaging quality when the first display area 10 is provided with a camera.
In addition, since the area of the white sub-pixel 17 in the first display region 10 is large, the pixel density of the first display region 10 is smaller than that of the second display region 20.
Optionally, with continued reference to fig. 3, along the second direction, the height of each sub-pixel in the first pixel row 11 is h1The height of each white sub-pixel 17 in the second pixel row 12 is h2，h2/h1λ is a positive integer of 2 or more.
Specifically, since the width of each sub-pixel in the first pixel row 11 is greater than or equal to the width of the white sub-pixel 17 in the second pixel row 12, and the area of each sub-pixel in the first pixel row 11 is smaller than the area of the white sub-pixel 17 in the second pixel row 12, the height of each white sub-pixel 17 in the second pixel row 12 is greater than the height of each sub-pixel in the first pixel row 11 along the second direction. In addition, the height of the white sub-pixel 17 is an integral multiple of the height of each sub-pixel in the first pixel row 11, for example, 2 times or 3 times, on one hand, the height of the white sub-pixel 17 is made to be an integral multiple of the height of each sub-pixel in the first pixel row 11, and the manufacturing process is easier to implement; on the other hand, when the height of the white sub-pixel 17 is 2 times or 3 times the height of each sub-pixel in the first pixel row 11, the light transmittance of the first display region 10 is the best.
