In the embodiment of the present application, laser is irradiated to the inside of the functional layer 200, so as to form the quantum dot light-blocking layer 300 and the quantum dot light-shielding layer 400 inside the functional layer 200, the plurality of light-emitting pixels 110 arranged at intervals of the quantum dot light-blocking layers 300 and the organic light-emitting layer 100 are correspondingly arranged, so that the quantum dot light-blocking layers 300 and the quantum dot light-shielding layer 400 can filter and adjust light entering the display module from the outside of the display module, that is, the problem of light reflection of the display module is solved, meanwhile, because the quantum dot light-blocking layers 300 are formed inside the functional layer 200, compared with the conventional scheme of stacking the functional layer 200 and the quantum dot light-blocking layers 300, the thickness of the display module can be reduced to a certain extent, and the display module is easy to fold. Therefore, the problem that the display module related to the related art has the difficult folding function of realizing can be solved in this application.
Optionally, the functional layers 200 include a touch layer 210, a cover plate 220, an optical adhesive layer 230 and an encapsulation layer 240, the touch layer 210, the optical adhesive layer 230 and the cover plate 220 are stacked in sequence, and the cover plate 220 is generally disposed on the outermost layer of the display module to protect the touch layer 210, meanwhile, the cover plate 220 has functions of impact resistance, scratch resistance, oil stain resistance, fingerprint resistance, light transmittance enhancement and the like, the optical adhesive layer 230 is generally a cemented transparent optical element and is used for connecting the cover plate 220 and the touch layer 210, the touch layer 210 is used for achieving a touch function of an electronic device, and the encapsulation layer 240 is used for preventing moisture and oxygen from penetrating into the display module.
At least one of the cover plate 220, the touch layer 210, the encapsulation layer 240 and the optical adhesive layer 230 has the quantum dot photo-resistance layer 300 and the quantum dot light-shielding layer 400, and specifically, at least one of the inside of the cover plate 220, the inside of the touch layer 210, the inside of the encapsulation layer 240 and the inside of the optical adhesive layer 230 has the quantum dot photo-resistance layer 300 and the quantum dot light-shielding layer 400, and the cover plate 220, the touch layer 210, the encapsulation layer 240 and the optical adhesive layer 230 may be used to protect the quantum dot photo-resistance layer 300 and the quantum dot light-shielding layer 400.

In another embodiment, the nanocrystals 250 may be separated out and formed into the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 under the action of laser, specifically, the nanocrystals 250 are irradiated by ultrafast laser to directly induce and generate the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 in the substrate, and in this way, the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 are generated by laser induction without a multi-pass photolithography process, so that the setting method may improve the production yield and reduce the cost.

In order to avoid the above influence, in another embodiment, at least one of the quantum dot light-blocking layer 300 and the quantum dot light-shielding layer 400 is located between the first surface 260 and the second surface 270, that is, at least one of the quantum dot light-blocking layer 300 and the quantum dot light-shielding layer 400 is disposed away from the outer surface of the functional layer 200, and further disposed away from the external environment, at this time, at least one of the quantum dot light-blocking layer 300 and the quantum dot light-shielding layer 400 can be prevented from being oxidized by water and oxygen in the environment, that is, the functional layer 200 has a better protection effect on at least one of the quantum dot light-blocking layer 300 and the quantum dot light-shielding layer 400, and meanwhile, the arrangement mode can effectively improve the optical performance of the quantum dot light-blocking layer 300 and the quantum dot light-shielding layer 400, and further improve the display effect of the display module.
Optionally, the quantum dot light-blocking layer 300 and the quantum dot light-shielding layer 400 may be disposed on different layers, and at this time, in the thickness direction of the functional layer 200, the space occupied by the quantum dot light-blocking layer 300 and the quantum dot light-shielding layer 400 is large, so that the thickness of the functional layer 200 is increased, and further the thickness of the display module is increased, which is not beneficial to the display module to realize the folding function.
Therefore, in another embodiment, the quantum dot light-blocking layer 300 and the quantum dot light-shielding layer 400 are disposed on the same layer, and at this time, the space of the functional layer 200 occupied by the quantum dot light-blocking layer 300 and the quantum dot light-shielding layer 400 in the thickness direction of the functional layer 200 is small, so that the thickness of the functional layer 200 is reduced, the thickness of the display module is reduced, and the display module is facilitated to realize a folding function. Meanwhile, the quantum dot light-blocking layer 300 and the quantum dot light-shielding layer 400 are arranged on the same layer, so that the quantum dot light-shielding layer 400 can better prevent the phenomenon of color crosstalk between the adjacent quantum dot light-blocking layers 300.
Optionally, the organic light emitting layer 100 further includes a pixel spacing portion 120, the pixel spacing portion 120 is disposed in a gap between adjacent light emitting pixels 110, and the pixel spacing portion 120 is used to prevent a color cross phenomenon between the adjacent light emitting pixels 110. In the thickness direction, a part of the orthographic projection contour line of the pixel spacing part 120 coincides with a part of the orthographic projection contour line of the quantum dot light-shielding layer 400, that is, a part of the pixel spacing part 120 is arranged opposite to a part of the quantum dot light-shielding layer 400, a part of the orthographic projection contour line of the light-emitting pixel 110 coincides with a part of the orthographic projection contour line of the quantum dot light-blocking layer 300, that is, a part of the light-emitting pixel 110 is arranged opposite to a part of the quantum dot light-blocking layer 300, at this time, only a part of light emitted by the light-emitting pixel 110 can pass through the quantum dot light-blocking layer 300, and thus the display effect of the display module is poor.
Therefore, in order to ensure the display effect of the display module, in another embodiment, all of the orthographic projection outlines of the pixel spacing portions 120 coincide with all of the orthographic projection outlines of the quantum dot light-shielding layers 400, that is, all of the pixel spacing portions 120 are disposed opposite to all of the quantum dot light-shielding layers 400, all of the orthographic projection outlines of the light-emitting pixels 110 coincide with all of the orthographic projection outlines of the quantum dot light-blocking layers 300, that is, all of the light-emitting pixels 110 are disposed opposite to all of the quantum dot light-blocking layers 300, at this time, all light emitted by the light-emitting pixels 110 can pass through the quantum dot light-blocking layers 300 disposed opposite thereto, so that the display module can display all the light, and the display effect of the display module is improved.
Alternatively, the plurality of light emitting pixels 110 includes a first light emitting pixel 111, a second light emitting pixel 112, and a third light emitting pixel 113, the color of the light emitted by the first light emitting pixel 111, the second light emitting pixel 112, and the third light emitting pixel 113 may be one of three primary colors, respectively, the plurality of quantum dot photoresist layers 300 includes a first photoresist layer 310, a second photoresist layer 320, and a third photoresist layer 330, and the color of the first photoresist layer 310, the second photoresist layer 320, and the third photoresist layer 330 may also be one of three primary colors, respectively.
The first light-emitting pixels 111 and the first photoresist layer 310 are arranged in the thickness direction, and the color of the light emitted by the first light-emitting pixels 111 may be different from the color of the first photoresist layer 310; the second light emitting pixels 112 and the second photoresist layer 320 are arranged in the thickness direction, and the color of the light emitted by the second light emitting pixels 112 may be different from the color of the second photoresist layer 320; the third light-emitting pixels 113 and the third photoresist layer 330 are arranged in the thickness direction, and the color of the light emitted by the third light-emitting pixels 113 may be different from the color of the third photoresist layer 330, but the arrangement may cause only a small portion of the light emitted by the first light-emitting pixels 111, the second light-emitting pixels 112, and the third light-emitting pixels 113 to pass through the corresponding photoresist layers, which results in poor color rendering of the display module.
In order to improve the color rendering of the display module, in another embodiment, the first light-emitting pixels 111 and the first photoresist layer 310 are arranged in the thickness direction, and the color of the light emitted by the first light-emitting pixels 111 is the same as the color of the first photoresist layer 310; the second light emitting pixels 112 and the second photoresist layer 320 are arranged in the thickness direction, and the color of the light emitted by the second light emitting pixels 112 is the same as the color of the second photoresist layer 320; the third light-emitting pixels 113 and the third photoresist layer 330 are arranged in the thickness direction, and the color of the light emitted by the third light-emitting pixels 113 is the same as the color of the third photoresist layer 330, so that most of the light emitted by the first light-emitting pixels 111, the second light-emitting pixels 112 and the third light-emitting pixels 113 can pass through the corresponding first photoresist layer 310, the second photoresist layer 320 and the third photoresist layer 330, and the color rendering of the display module is better.
