Referring to fig. 1, the display panel further includes an encapsulation layer 350, wherein the encapsulation layer 350 is formed on a side of the cathode layer 340 away from the substrate 100, and a light shielding layer 360 is formed on a side of the encapsulation layer 350 away 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 encapsulation layer 350 is formed between the cathode layer 340 and the light shielding layer 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 layer 360 is formed on the side of the encapsulation layer 350 away from the substrate 100, so that the distance between the light shielding layer 360 and the light emitting layer 330 can be increased, and the light emitting angle of the peep-preventing light emitting unit 332 can be conveniently adjusted.
Referring to fig. 1 and 2, the display panel further includes a color blocking layer 370 and an anti-reflection layer 380. The color resist layer 370 includes a plurality of color resists, which are red, green set, and blue, respectively. The orthographic projections of the display light emitting portions 331 on the substrate 100 are located in the orthographic projections of the color resistors on the substrate 100 in a one-to-one correspondence, that is, the orthographic projections of the red display light emitting portions R on the substrate 100 are located in the orthographic projections of the red color resistors on the substrate 100, the orthographic projections of the green display light emitting portions G on the substrate 100 are located in the orthographic projections of the green color resistors on the substrate 100, and the orthographic projections of the blue display light emitting portions B on the substrate 100 are located in the orthographic projections of the blue color resistors on the substrate 100.

When the light shielding unit 361 and the black matrix are arranged on the same layer, the light shielding unit 361, the black matrix and the color resistor have light-emitting gaps, and the light emitted by the peep-proof light-emitting unit can pass through the light-emitting gaps around the light shielding unit 361.
When the light shielding unit 361 and the black matrix are arranged in the same layer, the light shielding unit 361 and the black matrix can form a film layer for forming a specific pattern by adopting the same film forming process, and then a layer structure formed by adopting the same mask plate through a one-time composition process, namely, the one-time composition process corresponds to the one mask plate. 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.
In addition, in order to improve the contrast ratio of the display device and realize the integral black effect, the OLED display panel generally adopts a Polarizer (POL), which can effectively reduce the reflection intensity of the external ambient light on the 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 display panel in this embodiment includes an anti-reflection layer 380, where the anti-reflection layer 380 can reduce the reflection intensity of the external ambient light on the screen. In addition, the anti-reflection layer 380 also has a certain blocking effect, so that the OLED display panel can be protected. 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 light emitting part 331 is filtered, so that the polaroid of the OLED display panel can be canceled, the thickness of the functional layer can be greatly reduced, the light emitting rate can be improved from 44% to 80%, the light emitting brightness is greatly increased, and the power consumption of the OLED display panel can be reduced.
Example two
The second embodiment is different from the first embodiment in that the structure of the peep-proof light-emitting unit is different.
Referring to fig. 5, a light emitting layer 330 is formed on a side of the pixel defining layer 320 remote from the substrate 100, and the light emitting layer 330 includes a plurality of pixel units. The pixel unit includes a plurality of display light emitting portions 331 and at least one peep-proof light emitting unit, and the peep-proof light emitting unit includes at least two peep-proof light emitting portions 332 with different colors. For example, the peep-proof light-emitting unit comprises a red peep-proof light-emitting part and a green peep-proof light-emitting part, and the peep-proof light-emitting unit can generate yellow peep-proof light. Each display light-emitting part 331 and each peep-proof light-emitting unit are connected with the anode 311 in a one-to-one correspondence. At least part of adjacent peep-proof light-emitting units are connected, for example, two adjacent peep-proof light-emitting units in the row direction are connected or two adjacent peep-proof light-emitting units in the column direction are connected.
At least part of adjacent peep-proof luminous units are connected, the connected peep-proof luminous units can be designed to be larger than the independent peep-proof luminous units, and the efficiency of the peep-proof luminous units can be improved, so that the peep-proof effect of the display panel can be improved.
