Description

Technical Field

[0001] This application belongs to the field of display technology, specifically relating to a display panel and a display device. Background Technology

[0002] OLED (Organic Light-Emitting Diode) display panels have advantages such as being thin and light, flexible, high brightness, low power consumption, fast response, high definition, and wide color gamut, and are increasingly being used in electronic devices such as televisions, mobile phones, and laptops.

[0003] The active-emitting characteristic of organic light-emitting diodes (OLEDs) gives OLED display panels a wider viewing angle, typically reaching 170 degrees. While a wider viewing angle provides a better visual experience, users sometimes desire a narrower viewing angle to effectively protect trade secrets and personal privacy, avoiding business losses or embarrassment caused by information leaks.

[0004] Existing privacy screen panels rely on privacy films for privacy protection. When the privacy function is not needed, the film must be removed, making it inconvenient to switch the privacy function on and off. To address this issue, some display panels incorporate privacy pixels and a blocking structure. When the privacy pixel is activated, at narrow viewing angles, the light from the privacy pixel is blocked by the blocking structure, allowing the display to function normally. At wide viewing angles, the light from the privacy pixel passes through the surrounding blocking structure, interfering with the light from the display pixel and achieving privacy at large viewing angles. However, the blocking structure occupies design space for the display pixel, reducing the aperture ratio of the display panel. This loss in aperture ratio is particularly noticeable when wide-angle privacy protection is required. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0040] Example 1

[0041] See Figure 1 and Figure 2As shown, in this embodiment, the display panel includes a substrate 100, a driving circuit layer 200, an anode layer 310, a pixel definition layer 320, a light-emitting layer 330, a cathode layer 340, and a plurality of light-shielding units 361. The driving circuit layer 200 is formed on one side of the substrate 100, and the substrate 100 includes a glass substrate or a polyimide (Pi) substrate. The anode layer 310 is formed on the side of the driving circuit layer 200 away from the substrate 100, and the anode layer 310 includes a plurality of anodes 311. The pixel definition layer 320 is formed on the side of the anode layer 310 away from the substrate 100, and the pixel definition layer 320 includes a display pixel area and a privacy pixel area.

[0042] A light-emitting layer 330 is formed on the side of the pixel definition layer 320 away from the substrate 100. The light-emitting layer 330 includes a plurality of sub-pixels, each sub-pixel being connected to an anode 311. The plurality of sub-pixels includes a plurality of display sub-pixels 331 and a privacy sub-pixel 332. The plurality of display sub-pixels 331 are located in a plurality of display pixel areas, each display sub-pixel 331 being connected to an anode 311. The privacy sub-pixel 332 is located in a privacy pixel area, each privacy sub-pixel 332 being connected to an anode 311. A cathode layer 340 is formed on the side of the light-emitting layer 330 away from the substrate 100.

[0043] Multiple light-shielding units 361 are formed on the side of the cathode layer 340 away from the substrate 100. The orthographic projection of the privacy pixel 332 on the substrate 100 is located one-to-one within the orthographic projection of the light-shielding unit 361 on the substrate 100. The light-shielding unit 361 includes a main body 3611 and a drooping portion 3612 disposed around the edge of the main body 3611. The drooping portion 3612 extends toward the side closer to the substrate 100.

[0044] It should be noted that the multiple display sub-pixels 331 may include a red display sub-pixel R, a green display sub-pixel G, and a blue display sub-pixel B, but are not limited to these. The multiple display sub-pixels 331 may also all be white sub-pixels W or sub-pixels of other colors, depending on the specific circumstances. The privacy sub-pixel 332 may be a white sub-pixel W, but is not limited to this. The privacy sub-pixel 332 may also be a sub-pixel of other colors, depending on the specific circumstances. Both the multiple display sub-pixels 331 and the privacy sub-pixel 332 are made of organic light-emitting materials.

[0045] See Figure 3As shown, the display panel has a privacy mode. When the privacy mode is off, display sub-pixel 331 displays normally, while privacy sub-pixel 332 is off, and the display panel can be clearly displayed whether viewed directly or at an angle. When the privacy mode is on, privacy sub-pixel 332 is on, and its forward light emission is blocked by light-blocking unit 361. The forward light emission of display sub-pixel 331 is undisturbed, and the display panel can be clearly displayed when viewed directly. However, the oblique light emission of privacy sub-pixel 332 is not blocked by light-blocking unit 361, and the oblique light emission of display sub-pixel 331 mixes with the oblique light emission of privacy sub-pixel 332. The display panel cannot be clearly displayed when viewed at an angle, thus achieving the privacy function. The thickness direction of the display panel is the vertical direction, and the length direction of the display panel is the horizontal direction (horizontal direction in the figure). The larger the privacy angle to be achieved, the greater the horizontal boundary of light-blocking unit 361 exceeds the horizontal boundary value of privacy sub-pixel 332 (i.e., ...). Figure 3 The larger the value of X), the larger the space occupied by the light-shielding unit 361 on the display panel, and the greater the loss of the aperture ratio of the display panel.

[0046] In this embodiment, the light-shielding unit 361 includes a main body 3611 and a drooping portion 3612 disposed around the edge of the main body 3611. The drooping portion 3612 extends towards the side close to the substrate 100. The small-angle light of the privacy sub-pixel 332 is blocked by the drooping portion 3612, and the large-angle light of the privacy sub-pixel 332 mixes with the oblique light emitted by the display sub-pixel 331 to achieve the function of privacy protection. By increasing the drooping portion 3612 to block the oblique light emitted by the privacy sub-pixel 332, the size of the main body 3611 can be made smaller, thereby reducing the aperture ratio loss of the display panel.

[0047] See Figure 1 and Figure 2 As shown, the display panel also includes an encapsulation layer 350, which is located between the cathode layer 340 and the light-shielding unit 361. The orthographic projection of the drooping portion 3612 on the substrate 100 is located outside the orthographic projection of the privacy pixel 332 on the substrate 100.

[0048] The orthographic projection of the drooping portion 3612 on the substrate 100 is located outside the orthographic projection of the privacy pixel 332 on the substrate 100. In other words, while the lateral dimension of the privacy pixel 332 remains unchanged, the lateral dimension of the drooping portion 3612 (i.e., ...) is... Figure 3 The Y-axis can be designed to be longer and smaller, which can reduce the damage of the 350mm encapsulation layer and avoid affecting the encapsulation quality of the display panel.

[0049] See Figure 1 and Figure 2As shown, the display panel also includes a color resist layer 370 and a light-shielding layer 360. The color resist layer 370 includes multiple color resists, and the orthographic projection of the display sub-pixels 331 onto the color resist layer 370 is located within the color resists. The multiple display sub-pixels 331 may include a red display sub-pixel R, a green display sub-pixel G, and a blue display sub-pixel B. The multiple color resists may include red, green, and blue color resists, and the red, green, and blue color resists correspond one-to-one with the red display sub-pixel R, the green display sub-pixel G, and the blue display sub-pixel B. The light-shielding layer 360 includes a black matrix located around the color resists. In addition, the display panel also includes an anti-reflection layer 380, which is formed on the side of the color resist layer 370 away from the substrate 100.

[0050] To improve the contrast of display devices and achieve a seamless black effect, OLED display panels typically employ polarizers (POLs). Polarizers effectively reduce the intensity of ambient light reflection on the screen. However, the light transmittance of polarizers is generally only around 44%, requiring more power consumption to achieve higher brightness. Furthermore, polarizers are relatively thick and brittle, hindering the development of dynamically bending products.

[0051] This application employs a structure of color resist, black matrix, and anti-reflection layer 380. Red, green, and blue color resists filter light, while the black matrix is ​​placed around the color resists to block light. The anti-reflection layer 380 reduces the intensity of ambient light reflection on the screen. The polarizer of the OLED display panel can be eliminated, which not only greatly reduces the thickness of the functional layer but also increases the light output efficiency from 44% to 80%, significantly increasing the brightness. As a result, the power consumption of the OLED display panel is reduced.

[0052] See Figure 1 and Figure 2 As shown, the light-shielding unit 361 and the black matrix are set on the same layer.

[0053] It should be understood that in this application, "same-layer configuration" refers to a layer structure formed using the same film deposition process to create a specific pattern, and then using the same mask to form a single patterning process. That is, one patterning process corresponds to one mask. Depending on the specific pattern, a single patterning process may include multiple exposure, development, or etching processes. The specific pattern in the formed layer structure can be continuous or discontinuous, and these specific patterns may also be at different heights or have different thicknesses. This simplifies the manufacturing process, saves manufacturing costs, and improves production efficiency.

[0054] Setting the light-shielding unit 361 and the black matrix on the same layer not only simplifies the manufacturing process and saves manufacturing costs, but also ensures that the light-shielding unit 361 and the privacy pixel 332 have sufficient distance, reducing the alignment accuracy requirements of the light-shielding unit 361 and the privacy pixel 332.

[0055] See Figure 1 and Figure 2 As shown, the encapsulation layer 350 is located between the cathode layer 340 and the light-shielding layer 360. The encapsulation layer 350 includes a first inorganic encapsulation layer 351, and the drooping portion 3612 is located in the first inorganic encapsulation layer 351.

[0056] When manufacturing the display panel, a first inorganic encapsulation layer 351 is first formed. The thickness of the first inorganic encapsulation layer 351 is 0.5 micrometers to 2 micrometers, preferably 1.2 micrometers. Then, an annular groove is formed on the first inorganic encapsulation layer 351. The depth of the annular groove is less than the thickness of the first inorganic encapsulation layer 351. Then, a light-shielding unit 361 is formed by coating, exposure, and development. The thickness of the main body 3611 of the light-shielding unit 361 is 0.5 micrometers to 3 micrometers, preferably 1.5 micrometers. The drooping part 3612 of the light-shielding unit 361 is located in the annular groove.

[0057] The drooping portion 3612 is located in the first inorganic encapsulation layer 351, which can reduce the damage of the encapsulation layer 350 and avoid affecting the encapsulation quality of the display panel.

[0058] See Figure 1 and Figure 2 As shown, the encapsulation layer 350 also includes an organic encapsulation layer 352, which is located between the first inorganic encapsulation layer 351 and the cathode layer 340, and the drooping portion 3612 is located in the first inorganic encapsulation layer 351 and the organic encapsulation layer 352.

[0059] When manufacturing the display panel, an organic encapsulation layer 352 is first formed, with a thickness of 4 micrometers to 20 micrometers, preferably 12.5 μm. Then, an annular groove is formed on the organic encapsulation layer 352, followed by the formation of a first inorganic encapsulation layer 351 on the organic encapsulation layer 352. Finally, a light-shielding unit 361 is formed, with its drooping portion 3612 located in the annular groove.

[0060] The thickness of the organic encapsulation layer 352 is much greater than the thickness of the first inorganic encapsulation layer 351. The drooping portion 3612 is located in the first inorganic encapsulation layer 351 and the organic encapsulation layer 352. The vertical dimension of the drooping portion 3612 can be made longer, and the horizontal dimension of the main body portion 3611 can be made smaller, thereby reducing the aperture ratio loss of the display panel.

[0061] See Figure 1 and Figure 2As shown, the encapsulation layer 350 further includes a second inorganic encapsulation layer 353, which is located between the organic encapsulation layer 352 and the cathode layer 340. The thickness of the second inorganic encapsulation layer 353 is 0.5 micrometers to 2 micrometers, preferably 0.8 micrometers.

[0062] The inorganic encapsulation layer has a better water and oxygen barrier effect than the organic encapsulation layer 352. By setting a second inorganic encapsulation layer 353 between the organic encapsulation layer 352 and the cathode layer 340, the drooping part 3612 can be avoided from affecting the encapsulation quality of the display panel.

[0063] Example 2

[0064] The main difference between Embodiment 2 and Embodiment 1 is that the position of the light-shielding unit 361 is different.

[0065] See Figure 4 As shown, the encapsulation layer 350 includes a second inorganic encapsulation layer 353, an organic encapsulation layer 352, and a first inorganic encapsulation layer 351 formed sequentially. A plurality of light-shielding units 361 are formed between the first inorganic encapsulation layer 351 and the organic encapsulation layer 352, with at least the drooping portion 3612 located in the organic encapsulation layer 352.

[0066] The light-shielding unit 361 is formed between the first inorganic encapsulation layer 351 and the organic encapsulation layer 352. The first inorganic encapsulation layer 351 is undamaged, which can ensure the encapsulation quality of the display panel.

[0067] See Figure 4 As shown, the main body 3611 is located on the side of the organic encapsulation layer 352 away from the substrate 100, and the drooping portion 3612 is located in the organic encapsulation layer 352. The light-shielding unit 361 may be a metal structure layer with a thickness of 0.1 micrometer to 0.6 micrometers, preferably 0.4 micrometers.

[0068] It should be noted that the light-shielding unit 361 may be made of metal, but is not limited to this. The light-shielding unit 361 may also be made of black light-shielding material that forms a black matrix, depending on the specific circumstances.

[0069] The main body 3611 is located on the side of the organic encapsulation layer 352 away from the substrate 100. The light-shielding unit 361 is made of metal material, so the main body 3611 can be made thinner, and the foundation for forming the first inorganic encapsulation layer 351 is flatter. This reduces the risk of damage to the first inorganic encapsulation layer 351 and ensures the encapsulation quality of the display panel.

[0070] See Figure 4 As shown, the main body 3611 and the drooping part 3612 are both located in the organic encapsulation layer 352, and the side of the main body 3611 away from the substrate 100 is flush with the side of the organic encapsulation layer 352 away from the substrate 100.

[0071] When manufacturing the display panel, the second inorganic encapsulation layer 353 and the organic encapsulation layer 352 are formed sequentially. Then, an annular groove is formed on the organic encapsulation layer 352. Next, a light-shielding unit 361 is formed on the organic encapsulation layer 352. Finally, the first inorganic encapsulation layer 351 is formed.

[0072] The side of the main body 3611 away from the substrate 100 is flush with the side of the organic encapsulation layer 352 away from the substrate 100, making the base of the first inorganic encapsulation layer 351 flatter. This reduces the risk of damage to the first inorganic encapsulation layer 351 and ensures the encapsulation quality of the display panel.

[0073] Example 3

[0074] This application also provides a display device, see [link to relevant documentation] Figure 5 As shown, the display device includes a display panel 10 and a motherboard 20. The motherboard 20 is connected to the display panel 10 and is used to drive the display panel 10 to display an image. The display panel 10 includes the display panel 10 disclosed in Embodiment 1 and Embodiment 2.

[0075] The display device includes a display panel 10, which includes a substrate 100, a driving circuit layer 200, an anode layer 310, a pixel definition layer 320, a light-emitting layer 330, a cathode layer 340, and a plurality of light-shielding units 361 formed sequentially. The light-emitting layer 330 includes a plurality of display sub-pixels 331 and a privacy sub-pixel 332. The orthographic projection of the privacy sub-pixel 332 on the substrate 100 corresponds one-to-one with the orthographic projection of the light-shielding unit 361 on the substrate 100. The light-shielding unit 361 includes a main body 3611 and a drooping portion 3612 disposed around the edge of the main body 3611. The drooping portion 3612 extends toward the side closer to the substrate 100. The drooping portion 3612 blocks the oblique light emission of the privacy sub-pixel 332. The size of the main body 3611 can be made smaller, thereby reducing the aperture ratio loss of the display panel.
