[0120] Embodiment Six

[0121] The embodiment is the same as or similar to the above-mentioned embodiments, and the difference lies in that the features of the display panel 1000 in any one of the above-mentioned embodiments are further limited.

[0122] In some embodiments, the cover plate 30 further comprises a first protective layer 34, which is arranged on the side of the cover plate body 301 away from the substrate 10, and the first protective layer 34 covers the surface of the second light shielding layer 32 away from the substrate 10.

[0123] Specifically, the first protective layer 34 covers the surface of the second light shielding layer 32 away from the substrate 10, and the height of the first protective layer 34 on the cover plate body is greater than the height of the second light shielding layer 32 on the cover plate body.

[0124] Specifically, the first protective layer 34 is covered on the second light shielding layer 32. The first protective layer 34 can play a role in protecting the second light shielding layer 32, preventing the second light shielding layer 32 from peeling off the cover plate body 301, and preventing external objects from scratching or bumping the second light shielding layer 32.

[0125] Specifically, the material of the first protective layer 34 can include polyimide (Polyimide, abbreviated as PI), silica gel and the like.

[0126] In some embodiments, the display panel 1000 further comprises a support column 402 arranged between the cover plate 30 and the substrate 10.

[0127] Specifically, the support column 402 is used to support the cover plate 30 and the substrate 10, and maintain a predetermined distance between the cover plate 30 and the substrate 10.

[0128] Specifically, the support column 402 is used to support the cover plate 30 and the substrate 10, and can maintain the light condensing lens 331 and the corresponding light-emitting diode 20 arranged separately or not in contact, thereby improving the light condensing effect of the light condensing lens 331.

[0129] In some embodiments, such as Figure 3 and Figure 4 As shown, the display panel 1000 also includes a support column 402, which is disposed between the cover plate 30 and the substrate 10, and the light-concentrating lens layer 33 and the support column 402 are integrally formed structures.

[0130] Specifically, in Figure 3 In the implementation or embodiment three shown, in Figure 4 In the embodiment or example four shown, the condensing lens layer 33 and the support column 402 can be integrally formed. For example, the condensing lens layer 33 and the support column 402 are formed by the same imprinting process, which simplifies the manufacturing process. The imprinting process can be a die imprinting process or a hot imprinting process.

[0131] Specifically, in Figure 3 In the implementation or embodiment three shown, the first light-shielding member 311 is not provided at the condenser lens connector 332 part corresponding to the support column 402, or the first light-shielding member 311 at the condenser lens connector 332 part corresponding to the support column 402 is arranged side by side with the support column 402.

[0132] In some embodiments, the orthographic projection of the first opening 312 on the substrate 10 coincides with the orthographic projection of the corresponding second opening 322 on the substrate 10.

[0133] Specifically, the first light-shielding element 311 of the first light-shielding layer 31 and the second light-shielding element 321 of the second light-shielding layer 32 both serve to block the light emitted by adjacent light-emitting diodes. The first opening 312 and the second opening 322 both serve to allow the light emitted by the corresponding light-emitting diodes to pass through. The orthographic projection of the first opening 312 on the substrate 10 coincides with the orthographic projection of the corresponding second opening 322 on the substrate 10, so that the light-blocking effect of the first light-shielding element 311 of the first light-shielding layer 31 and the second light-shielding element 321 of the corresponding second light-shielding layer 32 is more sufficient, and the light transmission efficiency of the first opening 312 and the corresponding second opening 322 is greater, thus avoiding the reduction of both the light-blocking effect and the light transmission effect due to the misalignment of the first light-shielding layer 31 and the second light-shielding layer 32.
