Preferred embodiments of the present application are described in detail below, however, the present application may have other embodiments in addition to these detailed descriptions.
The embodiment of the application provides a display panel. Referring to fig. 2 and 3, the display panel includes a substrate 201, a light emitting unit 202, an auxiliary layer 203, and an encapsulation layer 204.
In order to clearly show the positional relationship between the light emitting unit 202 and the auxiliary layer 203 in fig. 2, the substrate 201 and the encapsulation layer 204 are not shown in fig. 2. But the location of the substrate 201 and the encapsulation layer 204 can be understood in connection with fig. 3.
The substrate 201 may be a rigid glass substrate or a flexible Polyimide (PI) substrate, including a buffer layer (SiNO x/SiNx) to improve the oxygen blocking capability.
A driving circuit may be further included on the substrate 201 to control the light emitting unit 202 to emit light.
A plurality of light emitting units 202 are disposed above the substrate base 201 at intervals. Wherein each light emitting unit 202 includes an anode layer 2021, a light emitting layer 2022, and a cathode layer 2023, which are sequentially stacked over the substrate base 201, each light emitting unit 202 is a single-color light emitting unit.
In some embodiments, since the size of the light emitting unit 202 depends on the size of the light emitting layer 2022, the cathode layer 2023 may be disposed entirely in the display panel, i.e., the cathode layers 2023 of the respective light emitting units 202 may be connected to each other.
In some embodiments, each light emitting unit 202 includes at least one pixel unit.
In some embodiments, the number of pixel units in the light emitting unit 202 may be 1, and the area of the 1 pixel unit is much larger than the pixel area of the mobile phone display screen.
In some embodiments, the number of pixel cells in the light emitting cell 202 is greater than or equal to 2, and the gap between any two adjacent pixel cells in the light emitting cell 202 is less than the gap between any two adjacent light emitting cells 202. In the light emitting unit 202, the gap between any two adjacent pixel units may be invisible to the naked eye, so that the overall display effect and appearance effect are not affected. In the light emitting unit 202, all the pixel units exhibit monochromatic light emission of the light emitting unit 202 together by voltage driving control of the anode layer 2021 and the cathode layer 2023.
The encapsulation layer 204 is located over the light emitting cells 202. The material of the encapsulation layer 204 includes an inorganic material and/or an organic material, and the encapsulation layer 204 is used to block external water, oxygen, etc. from entering the light emitting unit 202, so as to protect the light emitting unit 202.
In some embodiments, the encapsulation layer 204 includes a first inorganic film layer, an organic film layer over the first inorganic film layer, and a second inorganic film layer over the organic film layer.
The auxiliary layer 203 is disposed below the encapsulation layer 204 (i.e., between the encapsulation layer 204 and the substrate 201) and between any two adjacent light emitting units 202; wherein, the orthographic projection of the auxiliary layer 203 on the substrate 201 at least covers the gap between the orthographic projections of any two adjacent light emitting units 202 on the substrate 201, and the color of the corresponding auxiliary layer 203 between the two adjacent light emitting units 202 is the same as the light emitting color of any one of the two adjacent light emitting units 202.
The auxiliary layer 203 needs to ensure that the gaps between the light emitting units 202 are covered by the auxiliary layer 203.
That is, in the display panel, the auxiliary layer 203 serves as a light emission defining layer for defining the size of the light emitting layer 2022 (i.e., the size of the light emitting unit 202) and isolating two adjacent light emitting units 202.
In some embodiments, the cathode layer 2023 may extend above the auxiliary layer 203 to achieve full-face placement of the cathode layer 2023.
In some embodiments, the light emission colors of all light emitting units 202 in the display panel are the same, i.e., a single color illumination display is presented. At this time, the color of the auxiliary layer 203 coincides with the display color of the display panel to achieve color consistency of the entire surface.
In some embodiments, the light emission colors of all the light emitting units 202 in the display panel include at least two. That is, all of the light emitting units 202 may exhibit complex colors of different regions to meet actual lighting display requirements. At this time, the color of the auxiliary layer 203 (part) corresponding between the adjacent two light emitting units 202 is the same as the light emitting color of any one of the adjacent two light emitting units 202.
In some embodiments, the display panel is a bottom emission display panel, and light is emitted downward through the anode layer 2021.
Correspondingly, in some embodiments, the display panel further comprises: the reflective back film 205 is disposed above the encapsulation layer 204 to ensure that the light coming from the outside is fully reflected and reaches the auxiliary layer 203, so as to realize the uniformity of the overall display and improve the display effect and the appearance effect in the bright state and the dark state.
In some embodiments, the material of the reflective backing film 205 may be an Al film or the like having high reflectivity.
Correspondingly, since the auxiliary layer 203 is disposed between any two adjacent light emitting units 202 in the display panel, the auxiliary layer 203 has less influence on the light emitting effect of the light emitting units 202, so that the material of the auxiliary layer 203 may include a light shielding material or a transparent material in the display panel. Wherein the light shielding material comprises a light absorbing material or a reflecting material.
The material of the cathode layer 2023 includes a light shielding material, and the material of the anode layer 2021 includes a transparent material, so that light emitted from the light-emitting layer 2022 is emitted downward through the anode layer 2021 without being emitted upward from the cathode layer 2023.
In some embodiments, the material of the cathode layer 2023 may be a metal layer having high reflectivity, such as thick Ag or the like.
In some embodiments, the material of the anode layer 2021 may be transparent ITO or the like.

In some embodiments, the material of the transparent back film 205 may be transparent glass or the like,

The material of the cathode layer 2023 comprises a transparent material, and the material of the anode layer 2021 comprises a light shielding material, so that light emitted from the light-emitting layer 2022 is emitted upward through the cathode layer 2023, and is not emitted downward from the anode layer 2021. The material of the anode layer 2021 includes a light-shielding material with high reflectivity.
The embodiment of the application also provides another display panel. Referring to fig. 4, the display panel includes a substrate 301, a light emitting unit 302, a light emitting defining layer 303, a packaging layer 304 and an auxiliary layer 305.
The substrate 301 may be a rigid glass substrate or a flexible Polyimide (PI) substrate, including a buffer layer (SiNO x/SiNx) to improve the water-oxygen blocking capability.
The substrate 301 may further include a driving circuit thereon to control the light emitting unit 302 to emit light.
A plurality of light emitting units 302 are disposed above the substrate 301 at intervals. Wherein each light emitting unit 302 includes an anode layer 3021, a light emitting layer 3022, and a cathode layer 3023 stacked in this order over the substrate 301, each light emitting unit 302 being a single color light emitting unit.
In some embodiments, since the size of the light emitting unit 302 depends on the size of the light emitting layer 3022, in the display panel, the cathode layer 3023 may be disposed entirely, i.e., the cathode layers 3023 of the respective light emitting units 302 may be connected to each other.
In some embodiments, each light emitting cell 302 includes at least one pixel cell.
In some embodiments, the number of pixel units in the light emitting unit 302 may be 1, and the area of the 1 pixel unit is much larger than the pixel area of the mobile phone display screen.
In some embodiments, the number of pixel cells in the light emitting cell 302 is greater than or equal to 2, and the gap between any two adjacent pixel cells in the light emitting cell 302 is less than the gap between any two adjacent light emitting cells 302. In the light emitting unit 302, the gap between any two adjacent pixel units may be invisible to the naked eye, and the overall display effect and appearance effect are not affected. In this light emitting unit 302, all the pixel units collectively exhibit monochromatic light emission of the light emitting unit 302 by drive control of the voltage of the anode layer 3021.
The light emission defining layer 303 is disposed above the substrate 301 and between any two adjacent light emitting units 302. The light emission defining layer 303 is used to define the size of the light emitting layer 3022, i.e., the size of the light emitting unit 302, and to isolate adjacent two light emitting units 302.
In some embodiments, the cathode layer 3023 may extend above the light emission defining layer 303 to achieve an overall arrangement of the cathode layer 3023.
The encapsulation layer 304 is located over the light emitting cells 302. The material of the encapsulation layer 304 includes an inorganic material and/or an organic material, and the encapsulation layer 304 is used to block external water, oxygen, etc. from entering the light emitting unit 302, so as to protect the light emitting unit 302.
In some embodiments, the encapsulation layer 304 includes a first inorganic film layer, an organic film layer over the first inorganic film layer, and a second inorganic film layer over the organic film layer.
The auxiliary layer 305 is disposed above the encapsulation layer 304, wherein the front projection of the auxiliary layer 305 on the substrate 301 at least covers the gap between the front projections of any two adjacent light emitting units 302 on the substrate 301, and the color of the corresponding auxiliary layer 305 (part) between the two adjacent light emitting units 302 is the same as the light emitting color of any one of the two adjacent light emitting units 302.
The auxiliary layer 305 needs to ensure that the gaps between the light emitting units 302 are covered by the auxiliary layer 305.
In some embodiments, the light emission colors of all light emitting units 302 in the display panel are the same, i.e., a single color illumination display is presented. At this time, the color of the auxiliary layer 305 coincides with the display color of the display panel to achieve color consistency across the whole surface.
Correspondingly, in the display panel with single-color illumination display, the auxiliary layer 305 can be coated by the whole surface, so that overall beautiful shape is realized.
In some embodiments, the light emission colors of all the light emitting units 302 in the display panel include at least two. That is, all of the light emitting units 302 may exhibit complex colors of different regions to meet actual lighting display requirements. At this time, the color of the corresponding auxiliary layer 305 (part) between the adjacent two light emitting units 302 is the same as the light emitting color of any one of the adjacent two light emitting units 302.
In some embodiments, the display panel is a bottom emission display panel, and light is emitted downward through the anode layer 3021.
Correspondingly, in some embodiments, the display panel further comprises: the reflective back film 306 disposed above the encapsulation layer 304 is used to ensure that the light coming from the outside is fully reflected and reaches the auxiliary layer 305, so as to realize the uniformity of the whole display and improve the display effect and the appearance effect in the bright state and the dark state.
In some embodiments, the material of the reflective backing film 306 may be an Al film or the like having a high reflectivity,
Correspondingly, since the auxiliary layer 305 is disposed above the encapsulation layer 304 and also above the light emitting unit 302, the material of the auxiliary layer 305 includes a light shielding material to block the light emitted from the light emitting unit 302 from being emitted from above.
