Referring to fig. 6, optionally, the first display region 10 includes a plurality of first sub-pixels 110 arranged in an array, and the non-transmissive region 22 includes a plurality of second sub-pixels 210; the arrangement density of the second sub-pixels 210 is less than that of the first sub-pixels 110.
For example, in the embodiment shown in fig. 6, the first sub-pixel 110 includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B, and the second sub-pixel 210 includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B, in other embodiments, the first sub-pixel 110 and the second sub-pixel 210 may also be four color sub-pixels of red, green, blue, and white, and may be selected according to actual requirements in specific implementation. The arrangement density of the second sub-pixels 210 is smaller than that of the first sub-pixels 110, so that the area of the light transmission area 21 can be effectively increased, the light transmission performance of the second display area 20 is improved, and the imaging effect of the camera is improved.
Optionally, with continued reference to fig. 6, the area of the sub-pixels in the non-transmission region 22 is larger than the area of the sub-pixels in the first display region 10.
It is understood that when the sub-pixel density of the second display region 20 is decreased, the luminance of the second display region 20 is lower than the luminance of the first display region 10 under the same driving signal. By setting the area of the sub-pixel in the non-light-transmitting region 22 to be larger than the area of the sub-pixel in the first display region 10, the aperture ratio of the second display region 20 can be increased, the display brightness of the second display region 20 can be effectively improved, and the brightness difference between the first display region 10 and the second display region 20 can be weakened. For a full high definition (FHD, 1920 × 1080 resolution) display screen, the size of the sub-pixels in the first display area 10 may be set to (20-35) μmx (20-35) μm, the size of the sub-pixels in the first non-transparent area 221 may be set to (40-60) μmx (15-25) μm, and the size of the sub-pixels in the second non-transparent area 222 may be set to (30-50) μmx (100-180) μm.

However, the shapes of the first driving circuit 223 and the second driving circuit 224 are different, and in the exemplary fig. 7, the first driving circuit 223 and the second driving circuit 224 are both represented by rectangles, and since the width of the second non-light-transmitting region 222 is small and the length is long, the second driving circuit 224 matches the shape of the second light-transmitting region 222, and is a rectangle with a narrow width and a long length compared with the first driving circuit 223.

Since the touch electrode is generally made of an opaque metal material, in order to avoid the light transmittance performance of the second display area from being reduced, the touch electrode in this embodiment is formed by a grid-shaped metal trace, so as to avoid shielding the light transmittance area.
Optionally, with reference to fig. 11, the latticed metal traces in the second display area are located in the non-light-transmitting area 22, and at least a portion of the touch electrode 30 surrounds the light-emitting area of the sub-pixel.
Optionally, the touch electrode 30 includes a touch driving electrode 31, a touch sensing electrode 32, and a dummy electrode 33.
For example, the touch structure provided in this embodiment is a mutual capacitance touch structure, the touch electrode 30 includes a touch driving electrode 31(TX), a touch sensing electrode 32(RX), and a virtual electrode 33(Dummy), and when performing touch detection, touch position positioning is realized by detecting a capacitance value between the touch driving electrode 31 and the touch sensing electrode 32, for example, in this embodiment, the red sub-pixel R is mainly surrounded by the touch driving electrode 31, the green sub-pixel G is mainly surrounded by the touch sensing electrode 32, and the virtual electrode 33 is formed by cutting a portion of the touch driving electrode 31 or the touch sensing electrode 32, and is mainly disposed between the touch driving electrode 31 and the touch sensing electrode 32 to reduce coupling capacitance possibly caused by other traces. In specific implementation, the touch driving electrodes 31, the touch sensing electrodes 32 and the dummy electrodes 33 may be formed in the same layer, and the crossing positions of the touch driving electrodes 31 and the touch sensing electrodes 32 are connected by a bridge.
Optionally, the size of the light-transmitting region varies non-periodically along the row direction; and/or the size of the light-transmitting regions varies non-periodically along the column direction.
Fig. 12 to 14 are schematic structural diagrams of the second display region of another display panel according to an embodiment of the present invention, wherein the size of the light-transmissive region in the row direction varies non-periodically (a1 ≠ a2 ≠ a3) schematically shown in fig. 12, the size of the light-transmissive region in the column direction varies non-periodically (b1 ≠ b2 ≠ b3) schematically shown in fig. 13, and the size of the light-transmissive region in the row direction and the size of the light-transmissive region in the column direction vary non-periodically (a1 ≠ a2 ≠ a3, b1 ≠ b2 ≠ b3) schematically shown in fig. 14.
It can be understood that, when the light-transmitting area and the non-light-transmitting area are arranged at intervals, a grating structure can be formed, when light is transmitted through the light-transmitting area, multi-level diffraction stripes can be formed to influence the imaging effect of the camera, so that the size of the light-transmitting area can be set to be in aperiodic change along the row direction and/or the column direction, the diffraction of the light-transmitting area to the light can be reduced, and the imaging effect of the camera is improved. The difference in the sizes of the light-transmitting regions in the row direction or the column direction shown in fig. 14 is only schematic, and in particular, the sizes of some non-adjacent light-transmitting regions may be the same, so long as the non-periodic structure is satisfied.
