It should be noted that the light-condensing portion J may be formed by using the same material as the planarization layer 2 and/or the pixel defining layer 3, and the light-condensing portion J may form an effect similar to a convex lens by adjusting the material of the planarization layer 2 and the pixel defining layer 3, so that the light-condensing portion J can collect external light in a wider range, and further increase the light incident amount, and the light-condensing effect of the light-condensing portion J may be specifically achieved by adjusting the refractive indexes of the planarization layer 2 and the pixel defining layer 3.
It can be understood that, the first display area AA1 is a light transmission area for arranging optical elements such as a camera, and the light transmittance of the first display area AA1 is greater than that of the second display area AA2, so as to ensure that the first display area AA1 has a sufficient light entering amount, and improve the imaging effect.
Referring to fig. 2, in some alternative embodiments, the planarization layer 2 includes a first planarization layer 21 and a second planarization layer 22 stacked along a film stacking direction of the display panel, the light-gathering portion J extends from the pixel defining layer 3 to the first planarization layer 21, the first planarization layer 21 has a first groove for accommodating the light-gathering portion J, and a refractive index of the light-gathering portion J is greater than a refractive index of the first planarization layer 21.
It can be understood that the light-gathering portion J is formed by extending the pixel defining layer 3 to the first flat layer 21, and the light-gathering portion J may or may not pass through the first flat layer 21, that is, the first groove of the first flat layer 21 may be a through hole or a blind hole, in this embodiment, the light-gathering portion J does not extend to the second flat layer 22, so as to avoid affecting too many film structures, and the preparation is convenient. The refracting index of spotlight portion J is greater than the refracting index of first flat bed 21, and the refracting index is less relatively promptly light thinning medium, and the refracting index is the optically denser medium lower relatively, and according to the law of refraction, light can realize the spotlight effect from optically denser medium incident light thinning medium, can collect light on a wider range, and external light passes through spotlight portion J promptly and incides to first flat bed 21, and the concrete principle explains as follows:

Thus, light within the "a 1 and a 2" or "a 6 and a 7" angles can be focused between a and B. The convex lens structure plays a role in collecting light rays with larger angles above the display device.
Referring to fig. 3, in some alternative embodiments, the planarization layer 2 includes a first planarization layer 21 and a second planarization layer 22 stacked along a film stacking direction of the display panel, the light-gathering portion J extends from the pixel defining layer 3 to the second planarization layer 22, and the light-gathering portion J penetrates through the first planarization layer 21 and extends to the second planarization layer 22; the first flat layer 21 has a through hole for passing the light-condensing portion J, the second flat layer 22 has a second groove for receiving a portion of the light-condensing portion J, and the refractive indexes of the light-condensing portion J are both greater than those of the first and second flat layers 21, 22.
It can be understood that the light-gathering portion J formed by the pixel defining layer 3 penetrates through the first flat layer 21 and extends to the second flat layer 22, the refractive indexes of the light-gathering portions J are both greater than the refractive indexes of the first flat layer 21 and the second flat layer 22, so that the light-gathering portion J is used as an optically dense medium, the first flat layer 21 and the second flat layer 22 are used as an optically sparse medium, so as to form a convex lens structure, because the light-gathering portion J penetrates through the first flat layer 21 and extends to the second flat layer 22, the light-gathering portion J can be thicker, the light-gathering portion J has a larger thickness, the light-gathering effect can be effectively improved, and light rays are more concentrated.
In some alternative embodiments, the refractive index of the light-condensing portion J is 1.65 or more, and the refractive indices of the first and second planarization layers 21 and 22 are 1.6 or less. Specifically, the planarization layer 2 and the pixel defining layer 3 are made of transparent organic materials. For example, the material of any one of the planarization layer 2 and the pixel defining layer 3 may be hexamethyldisiloxane, epoxy resin, or Polyimide (PI), and may also be other silicon-based adhesive material, or Poly-p-Phenylene Benzobisoxazole (PBO) based material.
Referring to fig. 4, the light-gathering portion J is not limited to be formed on the pixel defining layer 3, and may also be formed by the planarization layer 2, in some alternative embodiments, the planarization layer 2 includes a first planarization layer 21 and a second planarization layer 22 stacked along the film stacking direction of the display panel, the second planarization layer 22 is disposed on a side of the first planarization layer 21 away from the pixel defining layer 3, the light-gathering portion J extends from the first planarization layer 21 to the second planarization layer 22, the second planarization layer 22 has a second groove for accommodating the light-gathering portion J, and the refractive index of the light-gathering portion J is greater than that of the second planarization layer 22.
It is understood that, in the present embodiment, since the light-condensing portion J is formed by the first planarization layer 21, the refractive index of the first planarization layer 21 is greater than that of the second planarization layer 22, and the first planarization layer 21 may be formed by using a high refractive index photoresist.
In some optional embodiments, the display panel further includes an anode layer 4, the pixel defining layer 3 includes a plurality of pixel openings, the anode layer 4 is at least partially disposed in the pixel openings, and an orthogonal projection of the anode layer 4 on the array substrate 1 and an orthogonal projection of the light-condensing portion J on the array substrate 1 are not overlapped.
It will be appreciated that the anode layer 4 is typically made of an opaque material, such as silver, titanium, etc. In order to avoid the anode layer 4 blocking the light-focusing portion J and affecting the light-focusing effect of the light-focusing portion J, the orthographic projection of the anode layer 4 on the array substrate 1 and the orthographic projection of the light-focusing portion J on the array substrate 1 are not overlapped, so that the anode layer 4 is prevented from blocking light from entering the light-focusing portion J.
Referring to fig. 7, in some optional embodiments, the display panel further includes a trace S disposed on at least one of the first flat layer 21 and the second flat layer 22, and the trace S is electrically connected to the anode layer 4 through a via hole, and an orthographic projection of the trace S on the array substrate 1 and an orthographic projection of the light-gathering portion J on the array substrate 1 are not overlapped.

In some optional embodiments, a support portion 5 is further included on a side of the pixel defining layer 3 facing away from the array substrate 1, and the material of the support portion 5 is the same as that of one of the pixel defining layer 3 and the planarization layer 2 without the light-gathering portion J.
It should be noted that, because the supporting portion 5 is disposed on the side of the pixel defining layer 3 away from the array substrate 1, the light-condensing portion J needs to be made of a high refractive index material, and the supporting portion 5 is made of the same material as the pixel defining layer 3 or the planarization layer 2 without the light-condensing portion J, that is, the supporting portion 5 is made of a low refractive index material, so as to prevent the supporting portion 5 from affecting the propagation path of the external light and adversely affecting the light-condensing effect of the light-condensing portion J. Specifically, when the light condensing portion J is formed of the pixel defining layer 3, the material of the support portion 5 is the same as the material of the planarizing layer 2, and when the light condensing portion J is formed of the planarizing layer 2, the material of the support portion 5 is the same as the material of the pixel defining layer 3.
