Referring to fig. 1, the display panel in this embodiment includes a substrate base 100, a driving circuit layer 200, an anode layer 310, a pixel defining layer 320, a light emitting layer 330, a cathode layer 340, a light shielding unit 360, and a first reflective layer 390. The driving circuit layer 200 is disposed on one side of the substrate 100, and the substrate 100 includes a glass substrate and a polyimide substrate.
The anode layer 310 includes a plurality of anodes 311, and the anode layer 310 is formed on a side of the driving circuit layer 200 remote from the substrate 100. The pixel defining layer 320 is formed on a side of the anode layer 310 away from the substrate 100, and the pixel defining layer 320 has a display pixel area 321 and a peep-proof pixel area 322. The light emitting layer 330 includes a plurality of sub-pixels, the sub-pixels are connected with the anode 311 in a one-to-one correspondence manner, the plurality of sub-pixels include a display sub-pixel 331 and a peep-proof sub-pixel 332, the display sub-pixel 331 is formed in the display pixel area 321, and the peep-proof sub-pixel 332 is formed in the peep-proof pixel area 322. That is, the display sub-pixel 331 and the peep-proof sub-pixel 332 are connected to different anodes 311 to realize separate control of the display sub-pixel 331 and the peep-proof sub-pixel 332. The display sub-pixel 331 may include a red sub-pixel, a green sub-pixel, and a blue sub-pixel, and the privacy sub-pixel 332 may include a white sub-pixel.
The cathode layer 340 is formed on the side of the light emitting layer 330 away from the substrate 100, and the display sub-pixel 331 and the peep-proof sub-pixel 332 are connected to the same cathode layer 340. The plurality of light shielding units 360 are formed on the side, far away from the substrate 100, of the cathode layer 340, the light shielding units 360 are in one-to-one correspondence with the peep-proof sub-pixels 332, and the projection of the peep-proof sub-pixels 332 in the thickness direction of the display panel is located in the corresponding light shielding units 360, namely, when in front view, the peep-proof sub-pixels 332 are completely shielded by the light shielding units 360. The first reflective layer 390 is formed between the peep-proof sub-pixel 332 and the anode 311, and the first reflective layer 390 can reflect at least a portion of the light of the peep-proof sub-pixel 332 to the periphery of the light shielding unit 360.
Note that, the peep-proof sub-pixel 332 may be a white sub-pixel, and the white sub-pixel may be formed by stacking a red light emitting material, a green light emitting material, and a blue light emitting material, but the peep-proof sub-pixel 332 may be a red sub-pixel, a green sub-pixel, a blue sub-pixel, a yellow sub-pixel, and the like, as the case may be. The arrangement of the red, green and blue display sub-pixels 331 and the peep-proof sub-pixels 332 may be optionally set, which is not limited in this embodiment.
Referring to fig. 2, the display panel has a peep-proof mode, when the peep-proof mode is closed, the display sub-pixel 331 is normally displayed, the peep-proof sub-pixel 332 is closed, and the display panel can clearly display in front view or oblique view. When the peep-proof mode is started, the peep-proof sub-pixel 332 is started, the forward light of the peep-proof sub-pixel 332 is blocked by the light shielding unit 360, the forward light of the display sub-pixel 331 is not interfered, and the display panel can clearly display in front view; the oblique light of the peep-proof sub-pixel 332 is not blocked by the light shielding unit 360, the oblique light of the display sub-pixel 331 is mixed with the oblique light of the peep-proof sub-pixel 332, and the display panel cannot clearly display under oblique viewing, so that the peep-proof effect is achieved.
When the peep-proof mode is started, since part of light of the peep-proof sub-pixel 332 is blocked by the light shielding unit 360, the light utilization rate of the peep-proof sub-pixel 332 is low, the light interference capability to the display sub-pixel 331 is not strong, and the peep-proof effect of the display panel is not ideal.
In this embodiment, the display panel is further provided with a first reflective layer 390, where the first reflective layer 390 is formed between the peep-proof sub-pixel 332 and the anode 311, and the first reflective layer 390 can reflect at least part of the light of the peep-proof sub-pixel 332 to the periphery of the light shielding unit 360, that is, the light utilization rate of the peep-proof sub-pixel 332 is improved, and in the peep-proof mode, the oblique light-emitting of the peep-proof sub-pixel 332 is increased, and the light mixing effect between the oblique light-emitting of the peep-proof sub-pixel 332 and the oblique light-emitting of the display sub-pixel 331 is enhanced, that is, the peep-proof effect of the display panel is better.
Referring to fig. 1, the display panel further includes an encapsulation layer 350, the encapsulation layer 350 is formed on a side of the cathode layer 340 remote from the substrate 100, and a light shielding unit 360 is formed on a side of the encapsulation layer 350 remote from the substrate 100. The encapsulation layer 350 includes a first inorganic encapsulation layer 351, an organic encapsulation layer 352, and a second inorganic encapsulation layer 353, the first inorganic encapsulation layer 351 being formed on a side of the cathode layer 340 remote from the substrate 100, the organic encapsulation layer 352 being formed on a side of the first inorganic encapsulation layer 351 remote from the substrate 100, the second inorganic encapsulation layer 353 being formed on a side of the organic encapsulation layer 352 remote from the substrate 100.
The first and second inorganic encapsulation layers 351 and 353 may be formed of SiNx, siOx, or SiOxNy materials, and the organic encapsulation layer 352 may be formed of acrylic, acrylate, epoxy, silicone, or the like materials. The first and second inorganic encapsulation layers 351 and 353 may be formed using a CVD (chemical vapor deposition) process, and the organic encapsulation layer 352 may be formed using an IJP (inkjet printing) process.
The encapsulation layer 350 is formed between the cathode layer 340 and the light shielding unit 360, and prevents the light emitting layer 330 formed of the organic light emitting material from being disabled by intrusion of water oxygen. The light shielding unit 360 is formed at a side of the encapsulation layer 350 away from the substrate 100, and the distance between the light shielding unit 360 and the light emitting layer 330 can be increased, so that the angle of the light reflected by the first reflective layer 390 can be adjusted.
It should be noted that, the light shielding unit 360 is formed on the side of the encapsulation layer 350 away from the substrate 100, but not limited thereto, and the light shielding unit 360 may be formed on the side of the encapsulation layer 350 close to the substrate 100, as the case may be. The light shielding unit 360 may also be formed on the side of the encapsulation layer 350 near the substrate 100, and a flat layer may be further disposed between the light shielding unit 360 and the cathode layer 340, so that the light shielding unit 360 and the light emitting layer 330 may be kept at a proper distance by the flat layer, and the risk of damage of the first inorganic encapsulation layer 351 may be reduced.
For example, referring to fig. 1, the light shielding unit 360 includes a second reflective layer 361, and the second reflective layer 361 is spaced apart from the side of the encapsulation layer 350 remote from the substrate 100. The second reflective layer 361 can be a metallic reflective layer. The projection of the second reflective layer 361 on the substrate 100 at least partially coincides with the projection of the first reflective layer 390 on the substrate 100, and the second reflective layer 361 can reflect at least a portion of the light of the peep-preventing sub-pixel 332 to the first reflective layer 390.
When the peep-proof mode is started, the peep-proof sub-pixel 332 is started, the second reflective layer 361 is irradiated by forward light emitted by the peep-proof sub-pixel 332, the second reflective layer 361 can reflect forward light emitted by the peep-proof sub-pixel 332 to the first reflective layer 390, the forward light emitted by the peep-proof sub-pixel 332 is secondarily reflected to the periphery of the light shielding unit 360 by the first reflective layer 390, the light utilization rate of the peep-proof sub-pixel 332 is improved, and then the light mixing effect of oblique light emitted by the peep-proof sub-pixel 332 and oblique light emitted by the display sub-pixel 331 is enhanced, namely, the peep-proof effect of the display panel is better.
Referring to fig. 1, the display panel further includes an anti-reflection layer 380, and the anti-reflection layer 380 is formed on a side of the second reflection layer 361 remote from the substrate 100.
In order to improve the contrast ratio of the display device and realize an integral black effect, a Polarizer (POL) is generally adopted in an OLED display panel, and the polarizer can effectively reduce the reflection intensity of external environment light on a screen. However, the light transmittance of the polarizer is generally only about 44%, and more power consumption is required to achieve higher light-emitting brightness. In addition, the polaroid has larger thickness and crisp material, and is not beneficial to the development of dynamic bending products.
The anti-reflection layer 380 is disposed on the side of the second reflection layer 361 away from the substrate 100, so that not only the reflection intensity of the external ambient light on the screen can be reduced, but also the reflection of the external ambient light by the first reflection layer 390 can be reduced. In addition, the anti-reflection layer 380 also has a certain blocking effect, so that the OLED display panel can be protected.
Referring to fig. 1, the display panel further includes a Black Matrix (BM) and a color block layer 370, wherein the color block layer 370 includes red, green and blue blocks that block the red, green and blue sub-pixels in one-to-one correspondence, and the Black Matrix is formed in surrounding areas of the red, green and blue blocks.
The reflection intensity of external environment light on the screen is reduced by adopting the anti-reflection layer 380, external light is blocked by adopting the color resistance layer 370, and the light emitted by the display sub-pixel 331 is filtered, so that the polaroid of the OLED display panel can be eliminated, the thickness of the functional layer is greatly reduced, the light emitting rate is greatly increased from 44% to 80%, the light emitting brightness is greatly increased, and the power consumption of the OLED display panel is reduced.
Referring to fig. 1, the pixel defining layer 320 includes a plurality of vias communicating with the anode electrode 311, and the peep-proof pixel region 322 includes the vias. That is, the peep-proof sub-pixel 332 is formed in the via. The first reflective layer 390 is an anode layer 310, and the anode layer 310 forms an uneven reflective surface on a side away from the substrate 100. The first reflective layer 390 covers at least the bottom region of the via, that is, the anode layer 310 also extends to the bottom surrounding region of the via.
It should be noted that the first reflective layer 390 may be the anode layer 310, but not limited thereto, and the first reflective layer 390 may be a reflective layer additionally disposed between the anode layer 310 and the light emitting layer 330, as the case may be.
The side surface of the anode layer 310, which is close to the light emitting layer 330, is made into an uneven reflecting surface, and the first reflecting layer 390 and the anode layer 310 are integrated into one layer, so that the structure of the display panel can be simplified, and the manufacturing cost of the display panel can be reduced.
Example two
The main difference between the second embodiment and the first embodiment is that the light shielding unit 360 has a different structure.
Referring to fig. 1 and 3, in the first embodiment, the light shielding unit 360 includes a first layer structure of the second reflective layer 361, and in the second embodiment, the light shielding unit 360 includes the second reflective layer 361 and the black light shielding layer 362, and the black light shielding layer 362 is disposed on a side of the second reflective layer 361 away from the substrate 100.
The light shielding unit 360 includes a second reflective layer 361 and a black light shielding layer 362, where the black light shielding layer 362 is disposed on a side of the second reflective layer 361 away from the substrate 100, and thus, the black light shielding layer 362 can reduce the reflection of the second reflective layer 361 to the external ambient light, which is beneficial to realizing an integrated black effect.
When the display panel further includes a color blocking layer 370 and a black matrix, the black light blocking layer 362 is disposed in the same layer as the black matrix.
It should be understood that "co-layer arrangement" in this application refers to a layer structure in which a film layer for forming a specific pattern is formed by using the same film forming process and then formed by using the same mask plate through a one-time patterning process, that is, one patterning process corresponds to one mask plate (also referred to as a photomask). Depending on the particular pattern, a patterning process may include multiple exposure, development, or etching processes, and the particular patterns in the formed layer structure may be continuous or discontinuous, and may be at different heights or have different thicknesses. Therefore, the manufacturing process is simplified, the manufacturing cost is saved, and the production efficiency is improved.
Example III
The main difference between the third embodiment and the first embodiment is that the first reflective layer 390 has a different structure. Referring to fig. 1 and 4, in the first embodiment, the first reflective layer 390 and the anode layer 310 are integrated into one layer, the side of the anode layer 310 near the light emitting layer 330 is made into a rugged reflective surface, and in the present embodiment, the first reflective layer 390 is a reflective layer additionally disposed between the anode layer 310 and the light emitting layer 330. The first reflective layer 390 includes a plurality of reflective structures formed on the anode 311. For example, the reflective structure is a raised structure or a granular structure.
The first reflective layer 390 is an additional reflective layer disposed between the anode layer 310 and the light emitting layer 330, and the anode 311 corresponding to the peep-proof subpixel 332 and the anode 311 corresponding to the display subpixel 331 can be manufactured by the same process.
When the first reflective layer 390 is an additional reflective layer disposed between the anode layer 310 and the light emitting layer 330, the first reflective layer 390 may be formed on the side of the anode 311 away from the substrate 100 and the via sidewall corresponding to the peep-preventing sub-pixel 332.
The side walls of the via holes are provided with reflecting surfaces, and part of light rays of the peep-proof sub-pixels 332 can be reflected to the periphery of the shading unit 360 from the first reflecting layers 390, so that light loss caused by multiple reflections is reduced.
Example IV
The main difference between the fourth embodiment and the first embodiment is that a diffusion unit 400 is further disposed between the light shielding unit 360 and the peep-proof sub-pixel 332, and the diffusion unit 400 may be a convex lens or other diffusion structure with high refractive index. The diffusion unit 400 may be formed at a side of the cathode layer 340 remote from the substrate 100 or in the organic encapsulation layer 352, and a projection of the diffusion unit 400 in a thickness direction of the display panel is located within the light shielding unit 360.
The diffusion unit 400 can refract the forward light emitted from the peep-proof sub-pixel 332 to the periphery of the shading unit 360, so as to improve the light utilization rate of the peep-proof sub-pixel 332, and further enhance the light mixing effect of the oblique light emitted from the peep-proof sub-pixel 332 and the oblique light emitted from the display sub-pixel 331, i.e. the peep-proof effect of the display panel is better. The diffusion unit 400 is disposed, the first reflective layer 390 and the anode layer 310 can be integrated into one layer, and a side surface of the anode layer 310, which is close to the light emitting layer 330, can be made into a plane, so that the anode 311 corresponding to the peep-proof sub-pixel 332 and the anode 311 corresponding to the display sub-pixel 331 can be made by adopting the same operation, and the manufacturing cost of the display panel can be reduced. In addition, the diffusion unit 400 can refract the forward light emitted by the peep-proof sub-pixel 332 to the periphery of the shading unit 360, so that the reflection times of the peep-proof sub-pixel 332 between two reflecting surfaces can be reduced, and the light loss caused by multiple reflection can be reduced.
