In the related art, if the sub-light-transmitting area AA and the sub-pixel area AB adopt rectangular light-transmitting holes, light is obviously diffracted in two directions perpendicular to the sides of the rectangle, and the imaging effect is affected; the circular light holes are adopted to enable imaging to be fuzzy, and therefore a balance level needs to be obtained between the circular light holes and the circular light holes, the edge profiles of the sub-light-transmitting area AA and the sub-pixel area AB are set to be polygons with the number of sides being larger than 4, the polygons are in shapes between rectangles and circles, phase superposition is avoided, interference is constructive or destructive, the influence of diffraction and interference effects on light uniformity is reduced, and image quality is improved to guarantee imaging definition while diffraction of the first display area A is reduced.
It should be noted that, the distribution density of the first pixel cells P1 in the first display area a is less than the distribution density of the second pixel cells P2 in the second display area B, so as to increase the light transmission area of the first display area a.
It can be understood that the display panel provided by the embodiment of the present invention is suitable for a display device which needs to be provided with a sensor under a screen, wherein the sensor may be a camera, for example. To match the edge profiles of the light-transmitting area and the pixel area, the first display area a is exemplarily shown as a polygonal area in fig. 1 and 2. In addition, the position of the first display area a in the display panel is not specifically limited in this embodiment, and fig. 1 only illustrates that the first display area a is located in the center area of the display panel, and in other alternative embodiments, the first display area a may also be located in the upper left corner of the display panel, and the like.
Referring to fig. 3, in some alternative embodiments, the plurality of sub-pixel areas AB includes a pixel central area AB2 and a plurality of pixel annular areas AB1 disposed around the pixel central area AB2 at equal intervals along the first direction Q, and the plurality of sub-transmissive areas AA includes a plurality of transmissive annular areas AA1 disposed at equal intervals along the first direction Q; the outer edge profiles of the pixel central region AB2, the plurality of pixel annular regions AB1, and the plurality of light-transmitting annular regions AA1 are the same.
It is understood that the plurality of sub-pixel regions AB includes a pixel central region AB2 and a plurality of pixel annular regions AB1 equally spaced along the first direction Q around the pixel central region AB2, the pixel central region AB2 is not annular but is a solid polygon having the same shape as the outer edge of the pixel annular region AB1, for example, when the pixel annular region AB1 is arranged in a regular pentagonal annular shape, the pixel central region AB2 is a regular pentagonal shape, it is understood that when the pixel central region AB2 includes only one sub-pixel, the anode of the sub-pixel takes a shape like the region AB2, that is, the anode of the sub-pixel and the forward projection of the region AB2 on the display panel completely coincide; when the pixel center area AB2 includes a plurality of sub-pixels, the outline of the outer edge of the area where the anodes of the plurality of sub-pixels are closely arranged and the orthographic projection of AB2 on the display panel completely coincide. Similarly, when the pixel annular region AB1 includes only one sub-pixel, the anode of the sub-pixel has an annular shape, and completely coincides with the orthographic projection of the AB1 region on the display panel; when the pixel annular region AB1 includes a plurality of sub-pixels, the outline of the outer edge of the region where the anodes of the sub-pixels are closely arranged and the orthographic projection of AB1 on the display panel completely coincide.

Referring to fig. 4, in another embodiment, the plurality of sub-pixel areas AB includes a plurality of pixel annular areas AB1 equally spaced along the first direction Q, and the plurality of sub-transmissive areas AA includes a transmissive central area AA2 and a plurality of transmissive annular areas AA1 equally spaced along the first direction Q around the transmissive central area AA2, that is, the transmissive central area AA2 is set as the sub-transmissive area AA, so as to increase the area of the transmissive area, thereby increasing the transmissive amount of the entire first display area a.
Referring to fig. 5, the outline shapes of the outer edges of the sub-pixel area AB and the sub-transmissive area AA may be regular hexagons.
Referring to fig. 6, in some alternative embodiments, the display panel includes a plurality of data lines extending along the second direction Y, the data lines include a first sub data line D1 and a second sub data line D2 overlapping with two adjacent sub light-transmissive areas AA, and the first sub data line D1 and the second sub data line D2 are electrically connected by a first connection line X1; the first connection line X1 is a transparent trace.
It can be understood that the first sub data line D1 and the second sub data line D2 may be respectively connected to the first pixel unit P1 of the two adjacent sub pixel areas AB to provide a data signal for each first pixel unit P1, and meanwhile, since the first sub data line D1 and the second sub data line D2 are electrically connected through the first connection line X1, the first connection line X1 needs to pass through the sub light transmission area AA, in order to avoid the light shielding effect of the first connection line X1 itself to affect the light transmission rate of the sub light transmission area AA, the first connection line X1 is set as a transparent line, specifically, the first connection line X1 may be made of a transparent conductive material such as transparent indium tin oxide.
Referring to fig. 7, in another embodiment, the display panel includes a plurality of scan lines extending along the third direction X, the scan lines include a first scan line and a second scan line overlapping two adjacent sub light-transmitting areas AA, and the first scan line and the second scan line are electrically connected by a second connection line X2; the second connecting line X2 is a transparent trace.
It can be understood that the plurality of scan lines extend along the third direction X, and optionally, the third direction X is perpendicular to the second direction Y, that is, the extending directions of the scan lines and the data lines are perpendicular to each other, and of course, the scan lines and the data lines are not limited to be straight lines, and may also be arranged in a curved line, so as to reduce the light diffraction effect between two adjacent scan lines or between two adjacent data lines.
Alternatively, the display panel may further include power supply signal lines (not shown), the power supply signal lines including first power supply signal lines extending in the second direction Y and second power supply signal lines extending in the third direction X, the first power supply signal lines being in the same layer as the data lines, the second power supply signal lines being in the same layer as the capacitor layer (not shown) of the pixel circuit layer 20, and the first power supply signal lines and the second power supply signal lines being electrically connected through vias in overlapping regions. .

It should be noted that, the first annular region AB11 and the second annular region AB12 are equally spaced apart from each other, and centers of the first annular region AB11 and the second annular region AB12 coincide with each other, specifically, opposite outer edges of the first annular region AB11 and the second annular region AB12 are parallel to each other, and optionally, centers of the first annular region AB11 and the second annular region AB12, i.e., centers of the pixel central regions AB2, are arranged to improve display uniformity of the pixel annular regions AB 1. Further, the edge profiles of the first annular area AB11 and the second annular area AB12 are regular pentagons. It should be noted that the edge profile specifically refers to the inner ring shape and the outer ring shape of the first annular region AB11 and the second annular region AB12, both of which are regular pentagons, except that the side length of the inner ring is smaller than that of the outer ring.
Referring to fig. 8, in order to realize the display of the display panel, in some alternative embodiments, the display panel includes: a substrate 1; a pixel circuit layer 20 disposed on one side of the substrate 1; the display device layer 30, the display device layer 30 is located on one side of the pixel circuit layer 20 far away from the substrate 1, the display device layer 30 comprises a plurality of first display devices F1 and a plurality of second display devices F2, the orthographic projection of the first display devices F1 on the plane of the substrate 1 is located in the pixel area, and the orthographic projection of the second display devices F2 on the plane of the substrate 1 is located in the second display area B; the pixel circuit layer 20 includes a plurality of pixel circuits including first pixel circuits connected in one-to-one correspondence with the plurality of first display devices F1; the first pixel circuit at least partially overlaps with the orthographic projection direction of the pixel area on the substrate 1.
It should be noted that the first display device F1 is disposed in the first display area a for implementing light emitting display of the first display area a, and the second display device F2 is disposed in the second display area B for implementing light emitting display of the second display area B, a forward projection of the first display device F1 on a plane where the substrate 1 is disposed is located in a pixel area, so as to avoid affecting light transmittance of a light-transmitting area, and the pixel circuit includes a first pixel circuit connected to the plurality of first display devices F1 in a one-to-one correspondence; the first pixel circuit at least partially overlaps with the orthographic projection direction of the pixel region on the substrate 1, and since the first pixel circuit generally includes a plurality of thin film transistors T1 and routing wires such as data lines, scan lines, power signal lines and the like connected to the thin film transistors T1, the orthographic projection direction of a part of the routing wires on the substrate 1 is located in the light-transmitting region, and thus, the first pixel circuit at least partially overlaps with the orthographic projection direction of the pixel region on the substrate 1, or completely overlaps with the orthographic projection direction of the pixel region on the substrate 1.
Optionally, a transition region (not shown in the figure) is further included, the transition region at least semi-surrounds the first display region a, the second display region BB at least semi-surrounds the transition region, the pixel density of the first display region a is less than that of the transition region, and the pixel density of the transition region is less than that of the second display region B; the first pixel circuit includes a thin film transistor T1 connected to the first display device F1, and at least a part of the thin film transistor T1 is located in a transition region in a front projection of the plane of the substrate 1.
Note that, in order to ensure the light transmittance of the first display region a, all of the thin film transistors T1 connected to the first display device F1 may be disposed in the transition region, the thin film transistors T1 are not disposed in the first display region a, and the pixel density of the transition region is between the pixel density of the first display region a and the pixel density of the second display region B. When displaying, the transition area can play a transition role, and the visual difference caused by the difference of the pixel density of the first display area A and the second display area B is reduced. Meanwhile, after the pixel density of the transition area is set to be smaller than that of the second display area B, a space is reserved in the transition area, and at least part of the thin film transistor T1 for driving the first sub-pixel can be arranged in the transition area, so that the area of the light-transmitting area of the first display area A can be further improved. The application in the scheme of the optical device under the screen can increase the light quantity received by the optical device.
Referring to fig. 9, in some alternative embodiments, the first display device F1 and the second display device F2 include an anode, a light emitting layer 8, and a cathode 9, which are stacked; the cathode 9 of the first display device F1 includes a plurality of electrically connected sub-cathodes 91, the sub-cathodes 91 coinciding with the orthographic projections of the respective sub-pixel areas AB.
It will be appreciated that each sub-cathode 91 of the cathode 9 of the first display device F1 coincides with the orthographic projection of each sub-pixel area AB, i.e. the outer edge profile of each sub-cathode 91 is also polygonal with a number of sides greater than 4. And since each sub-cathode 91 needs to be an electrically connected whole, each sub-cathode 91 needs to be connected together by providing the cathode connection part 92, etc.
Optionally, each sub-cathode 91 is electrically connected through a cathode connection portion 92, and the cathode connection portion 92 and the sub-transmissive area AA at least partially overlap in the orthogonal projection direction on the substrate 1; the cathode connection portion 92 is a transparent electrode. Specifically, since the cathode connection portion 92 and the sub-transmissive area AA are at least partially overlapped in the orthogonal projection direction on the substrate 1, in order to avoid the influence of the cathode connection portion 92 on the transmission of the light of the sub-transmissive area AA, the cathode connection portion 92 is made of a transparent electrode, and may be made of a transparent conductive material such as transparent indium tin oxide.
For each display device, by applying a voltage to the anode and the cathode 9, respectively, electrons and holes are recombined in the light emitting layer 8 to emit light, thereby realizing a pixel display function. The larger the distance between the anodes of the adjacent display devices is, the smaller the corresponding pixel density is, and thus, the distance between the anodes of the adjacent two first display devices F1 is greater than the distance between the anodes of the adjacent two second display devices F2, that is, the pixel density of the first display region a is less than the pixel density of the second display region B.
Referring to fig. 10, on the basis of the above embodiment, the pixel circuit layer 20 includes an active layer 2, a gate metal layer 3, a source-drain metal layer 5, an anode metal layer 7, and a planarization layer 6, which are stacked; the first metal layer M1 is provided between the source/drain metal layer 5 and the anode metal layer 7, and the cathode connection portion 92 and the first metal layer M1 are provided in the same layer.
It should be noted that, by arranging the cathode connection portion 92 and the first metal layer M1 on the same layer, an additional process is not required, the process flow is reduced, and the manufacturing cost of the display panel is reduced, it can be understood that a planarization layer 6 and other film layers are arranged between each sub-cathode 91 and the cathode connection portion 92 at intervals, and specifically, the sub-cathode 91 and the cathode connection portion may be connected by arranging via holes, and the interlayer insulating layer 4 is arranged between the gate metal layer 3 and the source and drain metal layer 5, so that the gate metal layer 3 and the source and drain metal layer 5 are insulated.
In order to reduce the depth of the via hole and avoid the problem of connection between the sub-cathodes 91 and the cathode connection portion 92, referring to fig. 11, in another embodiment, the cathode connection portion 92 and the anode metal layer 7 are disposed on the same layer, because the anode metal layer 7 is located on one side of the first metal layer M1 close to each sub-cathode 91, and the distance between the anode metal layer and the sub-cathode 91 is closer, the length of the trace can be reduced.
