Description

Technical Field

[0001] The present application belongs to the field of display technology, and in particular, relates to a display panel and a display device. Background Art

[0002] Organic Light-Emitting Diode (OLED) displays have many advantages, such as self-luminescence, low driving voltage, high luminous efficiency, short response time, high clarity and contrast, nearly 180° viewing angle, wide operating temperature range, flexible display and large-area full-color display, etc. They are recognized by the industry as the display device with the most development potential.

[0003] With the continuous advancement of display technology, the viewing angle of displays is constantly widening. People not only want to enjoy the viewing experience of a wide viewing angle, but also want to protect their personal privacy in certain scenarios to avoid embarrassment or property loss caused by the leakage of screen information. Therefore, the width and direction of the display screen viewing angle we need are different in different occasions, and traditional anti-peeping displays will block all light from the left and right directions, leaving only a viewing angle of about 30° above the screen, thereby achieving an anti-peeping effect. However, blocking the light from the left and right directions reduces the brightness of the entire display screen by about 33.3%.

[0004] In summary, in order to achieve the anti-peeping effect, the existing anti-peeping display will significantly reduce the display brightness of the display screen, resulting in the problem of poor display effect. Summary of the invention

[0007] substrate;

[0008] A pixel definition layer is arranged in an array and at intervals on one side of the substrate;

[0009] A pixel layer, located on the same side of the substrate as the pixel definition layer, and located between two adjacent pixel definition layers;

[0010] A shading unit is located at a side of the pixel definition layer away from the substrate, and the shading unit is located within the orthographic projection of the pixel definition layer along the thickness direction of the display panel;

[0012] In some embodiments, the first lens is a convex lens, and two ends of the first lens are respectively connected to the adjacent pixel definition layers.

[0013] In some embodiments, one end of the second lens is connected to an edge of the pixel definition layer close to the first lens, and the second lens has an inclined refractive surface, which is inclined from one end close to the pixel definition layer toward the middle of the display area.

[0014] In some embodiments, the cross-sectional shape of the second lens is at least one of a triangle, a trapezoid, a rhombus, and a parallelogram.

[0015] In some embodiments, a plurality of lens units are provided, and one lens unit includes one first lens and two second lenses.

[0016] In some embodiments, the display panel further includes an encapsulation layer, the encapsulation layer is located between the pixel definition layer and the shading unit, the first lens and the second lens are located in the encapsulation layer, and the refractive index of the second lens is less than the refractive index of the encapsulation layer.

[0017] In some embodiments, the shading unit includes a first conductive layer, an electrochromic layer, and a second conductive layer stacked in sequence, and the first conductive layer and the second conductive layer are transparent conductive layers;

[0018] When the display panel is in a normal display mode, the electrochromic layer is in a transparent state;

[0019] When the display panel is in the anti-peeping mode, the first conductive layer and the second conductive layer are energized to change the color of the electrochromic layer to a non-transparent state, the orthographic projection of the pixel definition layer along the thickness direction of the display panel forms the anti-peeping area, and the orthographic projection of the pixel layer along the thickness direction of the display panel forms the display area.

[0020] In some embodiments, a reflective structure is disposed between the first conductive layer and the electrochromic layer, and the reflective structure is used to reflect light emitted by the pixel layer and then reflected by the second conductive layer.

Specifically, the light emitted by the pixel layer is emitted from all directions. When the display panel is in the normal display mode, most of the forward light is directly emitted to the display area for display, and some of the light can also reach a good display through the side light; however, when the display panel is in the anti-peeping mode, due to the presence of the shading unit, the light emitted to the anti-peeping area will be blocked, thereby reducing the light utilization rate, and ultimately resulting in insufficient display brightness of the display panel; under the cooperation of the first lens and the second lens of the embodiment of the present application, the light emitted from the pixel layer to the left and right sides is first collected and then refracted through the second lens, so that these lights can be emitted in the display area, thereby achieving the effect of improving the light utilization rate and improving the display brightness of the display panel.

[0048] A first aspect of an embodiment of the present application provides a display panel, such as Figures 1 to 7 As shown, the display panel includes a substrate 10, a pixel definition layer 20, a pixel layer 30, a light shielding unit 40 and a lens unit 50;

[0049] The pixel definition layer 20 is arrayed and spaced apart on one side of the substrate 10;

[0050] The pixel layer 30 and the pixel definition layer 20 are located on the same side of the substrate 10 , and the pixel layer 30 is located between two adjacent pixel definition layers 20 ;

[0051] The light shielding unit 40 is located on a side of the pixel definition layer 20 away from the substrate 10, and the light shielding unit 40 is located within the orthographic projection of the pixel definition layer 20 along the thickness direction of the display panel;

[0052] The lens unit 50 includes a first lens 51 and a second lens 52. The first lens 51 is located on a side of the pixel layer 30 away from the substrate 10, and the second lens 52 is located on a side of the pixel definition layer 20 away from the substrate 10. The first lens 51 and the second lens 52 cooperate to refract at least part of the light emitted by the pixel layer 30 into the display area 300.

[0053] The display panel provided in the embodiment of the present application, by adding a lens unit 50, collects and refracts the light emitted by the pixel layer 30 to emit into the display area 300, thereby increasing the intensity of the forward light emitted by the display panel and effectively reducing the side light, thereby achieving the goal of improving the light utilization rate and reducing the light loss rate in the anti-peeping mode. Specifically, the light emitted by the pixel layer 30 is emitted from all directions. When the display panel is in the normal display mode, most of the light is directly emitted in the forward direction to the display area 300 for display, and some light can also reach a good display through the side light; however, when the display panel is in the anti-peeping mode, due to the presence of the shading unit 40, the light emitted to the anti-peeping area 200 will be blocked, thereby reducing the light utilization rate, and ultimately resulting in insufficient display brightness of the display panel; under the cooperation of the first lens 51 and the second lens 52 of the embodiment of the present application, the light emitted from the pixel layer 30 to the left and right sides is first collected and then refracted through the second lens 52, so that these lights can be emitted in the display area 300, thereby achieving the effect of improving the light utilization rate and improving the display brightness of the display panel.

[0054] In application, in OLED display panels, the choice of substrate 10, i.e., substrate material, is very important because it not only determines the physical properties and performance of the display panel, but also affects the cost and complexity of the manufacturing process. In the embodiment of the present application, the material of the substrate 10 includes, but is not limited to, glass, polyimide, poly(ethylene glycol) dicarboxylate, polyester and the like. The role of the substrate 10 in the display panel is mainly to provide physical support so that the semiconductor layer (pixel layer 30, pixel definition layer 20, etc.) can be stably deposited thereon. In addition, it is to ensure the planarity and stability of the entire display panel, as well as specific optical transparency, etc., which can increase the display brightness of the display panel. According to the specific application requirements (such as whether flexible and foldable characteristics are required), the most suitable substrate material will be selected to meet these requirements. With the advancement of technology, new substrate materials and technologies will continue to emerge to improve the performance of OLED display panels and reduce costs.

[0055] In applications, the pixel defining layer 20 (PDL) is a very important component in the display panel, which is crucial to ensure the correct formation and display quality of pixels. The functions of the pixel defining layer 20 are: defining the pixel area, that is, defining the exact boundaries of each pixel, ensuring that the organic material is deposited only at the predetermined location. It can help to accurately control the size and shape of each pixel. Prevent material diffusion. PDL can prevent the organic materials between adjacent pixels from diffusing each other, thereby maintaining the independence and clarity of the pixels. This helps to improve the contrast and color purity of the display panel. It can also improve the resolution. By accurately controlling the size and position of the pixels, PDL helps to achieve higher resolution. It can also play a certain protective role to prevent the organic materials from being affected by the external environment.

[0056] In applications, such as Figure 1 and Figure 2 As shown, the pixel layer 30 generally refers to a hierarchical structure including all necessary components constituting a single pixel, including an anode layer 31, a light-emitting layer 32, and a cathode layer 33;

[0057] Anode layer 31 : is usually a transparent conductive layer, such as indium tin oxide (ITO), used to inject holes into the light-emitting layer 32 .

[0058] Light-emitting layer 32: This is the part that actually emits light, and is composed of one or more layers of organic compounds. These compounds can emit photons when excited by electric current.

[0059] Cathode layer 33: usually a low work function metal, such as magnesium silver alloy or aluminum, used to inject electrons into the organic layer.

[0060] These layers work together to form a basic unit that can emit light, namely a pixel. In other embodiments, different OLED designs may have additional functional layers, such as a hole transport layer, an electron transport layer, a hole blocking layer, etc., which can also be regarded as part of the pixel layer 30.

[0061] In some embodiments, Figure 1As shown, the first lens 51 is a convex lens, and the two ends of the first lens 51 are respectively connected to the adjacent pixel definition layer 20. The convex lens can collect the light emitted from the pixel layer 30, so that the light originally emitted to the left and right sides is refracted by the convex lens and emitted toward the middle, thereby improving the utilization rate of light and improving the display brightness. In particular, when the display panel is in the anti-peep mode, the shading unit 40 located above the pixel definition layer 20 can block the light emitted from the pixel layer 30 that is biased to the left and right sides, which ultimately leads to a decrease in the brightness of the display area 300. The presence of the convex lens can effectively collect the light on both sides and emit it from the display area 300, effectively improving the display brightness of the display panel in the anti-peep mode. In application, the thickness of the two ends of the first lens 51 is less than the thickness of the middle part of the first lens 51, so as to ensure that the light emitted from the pixel layer 30 can be collected, the emission angle of the light is reduced, and the light is emitted from the display area 300 as much as possible.

[0062] In some embodiments, Figure 3 and Figure 4 As shown, one end of the second lens 52 is connected to the edge of the pixel definition layer 20 close to the first lens 51, and the second lens 52 has an inclined refractive surface 520, which is inclined from the end close to the pixel definition layer 20 toward the middle of the display area 300. In other words, through the inclined refractive surface 520 of the second lens 52, the light originally intended to be directed to the shading unit 40 can be further refracted, so that the light can be emitted from the display area 300 (i.e., the positive projection of the pixel layer 30 in the thickness direction of the display panel). In some embodiments, the second lens 52 is a micro lens, which has a small volume, is easy to process, and is stably arranged on the pixel definition layer 20.

[0063] In some embodiments, the cross-sectional shape of the second lens 52 is at least one of a triangle, a trapezoid, a rhombus, and a parallelogram. In a preferred embodiment, the cross-sectional shape of the second lens 52 is a triangle. Since the second lens 52 mainly refracts the inclined refractive surface 520 close to the pixel layer 30, the triangular lens has a corresponding inclined refractive surface 520, and can effectively save materials. In addition, the stability of the triangle is also utilized, so that the triangular second lens 52 can be stably arranged in the display panel.

[0064] In some embodiments, Figure 3 and Figure 4 As shown, a plurality of lens units 50 are provided, and one lens unit 50 includes a first lens 51 and two second lenses 52. The two second lenses 52 are located on both sides of the first lens 51, and are used to refract the light passing through the left and right sides of the first lens 51, respectively, so that more light is emitted from the display area 300, thereby improving the display brightness.

[0065] In some embodiments, Figure 1 , Figure 3 as well as Figure 4 As shown, the display panel further includes an encapsulation layer 60, which is located between the pixel definition layer 20 and the shading unit 40, and the first lens 51 and the second lens 52 are located in the encapsulation layer 60, and the refractive index of the second lens 52 is less than the refractive index of the encapsulation layer 60. Such a configuration is, on the one hand, to reduce the reflection phenomenon between the interface of the encapsulation layer 60 and the second lens 52, and reduce the loss of light; on the other hand, when the light is refracted by the second lens 52, it is more inclined to be emitted into the display area 300.

[0066] In applications, the material of the encapsulation layer 60 is usually inorganic materials such as glass or ceramics to provide a high-strength physical barrier to effectively isolate water vapor and oxygen. Its main function is to isolate water vapor and oxygen: prevent water vapor and oxygen from penetrating into the OLED layer, extend the service life of the display panel, and also provide physical protection for the display panel to prevent damage to the OLED layer by the external environment, as well as prevent scratches, improve the wear resistance and scratch resistance of the display panel, improve display quality, and enhance reliability.

[0067] In some embodiments, Figure 5 and Figure 6 As shown, the shading unit 40 includes a first conductive layer 41, an electrochromic layer 42 and a second conductive layer 43 which are stacked in sequence, and the first conductive layer 41 and the second conductive layer 43 are transparent conductive layers;

[0068] When the display panel is in the normal display mode, the electrochromic layer 42 is in a transparent state;

[0069] When the display panel is in the anti-peeping mode, the first conductive layer 41 and the second conductive layer 43 are energized to change the electrochromic layer 42 to a non-transparent state, and the orthographic projection of the pixel definition layer 20 along the thickness direction of the display panel forms an anti-peeping area 200, and the orthographic projection of the pixel layer 30 along the thickness direction of the display panel forms a display area 300.

[0070] In applications, such as Figure 5 As shown, when the display panel is in the normal display mode, the electrochromic layer 42 is transparent. At this time, the light emitted by the pixel layer 30 is emitted from the forward direction of the display panel, and the light will not be blocked by the shading unit 40, and all areas of the entire display panel can display normally. Figure 6As shown, the electrochromic layer 42 is in a non-transparent state (for example, it can be black or other dark colors), and light cannot be transmitted through the electrochromic layer 42, but can only be emitted from the display area 300, thereby achieving the effects of light shielding and peeping prevention. In summary, the display panel provided in the embodiment of the present application can achieve free switching between wide-angle viewing angle and narrow viewing angle.

[0071] In applications, the electrochromic layer 42 can change its optical properties, such as color or transparency, by applying voltage. The electrochromic layer 42 generally includes an electrochromic material layer, an electrolyte layer, and an ion storage layer.

[0072] The electrochromic material layer is the main active component of the electrochromic layer 42, which can change color or transparency in a redox reaction. Commonly used electrochromic materials include transition metal oxides (such as tungsten oxide WO3, nickel oxide NiO, etc.) and conductive polymers (such as polythiophene derivatives). The electrolyte layer provides a path for ion transmission, allowing ions to move between the electrochromic layer 42 and the ion storage layer. This layer can be a liquid electrolyte (such as a solution containing Li⁺ ions) or a solid electrolyte (such as a gel-like substance containing Li⁺). The ion storage layer is responsible for storing ions generated in the electrochromic layer 42 to maintain the charge balance of the entire system.

[0073] In some embodiments, the ion storage layer may use the same material as the electrochromic layer 42 but have the opposite electrochromic behavior to achieve complementary or superimposed colors.

[0074] In application, the working principle of the electrochromic layer 42 is as follows: when a forward voltage is applied, the electrochromic material absorbs ions and changes its oxidation state, resulting in a change in color or transparency.

[0075] When a reverse voltage is applied or the voltage is turned off, ions return from the electrochromic layer 42 to the ion storage layer, and the electrochromic material returns to its original state.

[0076] In some embodiments, Figure 7 As shown, a reflective structure 70 is provided between the first conductive layer 41 and the electrochromic layer 42. The reflective structure 70 is used to reflect the light emitted by the pixel layer 30 and then reflected by the second conductive layer 43. In application, although the first conductive layer 41 and the second conductive layer 43 are transparent conductive layers with a transmittance of about 80%, some light will still be reflected back. Therefore, a reflective structure 70 is provided between the electrochromic layer 42 and the first conductive layer 41. Figure 7 As shown, in the normal display mode of the display panel, part of the light reflected by the first conductive layer 41 is reflected back through the reflective structure 70, thereby reducing the loss of light, improving the light utilization rate, and helping to reduce the power consumption of the display panel.

[0077] In some embodiments, the reflective structure 70 has a plurality of reflectors 71, and the reflector 71 has a first reflective surface 710 and a second reflective surface 711. One end of the first reflective surface 710 is connected to the first conductive layer 41, one end of the second reflective surface 711 is connected to the first conductive layer 41, the other end of the first reflective surface 710 is connected to the other end of the second reflective surface 711, and the angle formed by the first reflective surface 710 and the second reflective surface 711 is an acute angle. Through the cooperation of the first reflective surface 710 and the second reflective surface 711, the light reflected by the first conductive layer 41 is reflected again, so that it is emitted in the display area 300, thereby improving the display brightness of the display panel.

[0078] In some embodiments, the reflective structure 70 is a prism film, which is a special optical film designed to enhance the overall brightness of the display panel through the refraction / reflection and guiding mechanism of light.

[0079] The surface of the prismatic film usually has many tiny prismatic structures, which can be a prism array with a triangular cross-section. The size of these prisms is very small, usually at the micron level, so that light can be effectively managed without affecting the display quality. The prismatic film changes the direction of the incident light through the micro-prismatic structure on its surface, redirecting scattered or deviated light in the vertical direction to the vertical direction, thereby increasing the brightness under the front viewing angle. This helps to increase the brightness when viewing from the front while reducing the brightness loss when viewing from the side. By directing more light to the front observer, the prismatic film is able to increase the brightness of the display panel. At the same time, since light leakage from the side is reduced, this also improves the contrast of the display panel.

[0080] A second aspect of an embodiment of the present application provides a display device, which includes the display panel described in the first aspect of the embodiment of the present application and a shell (not shown in the figure), and the display panel is arranged in the shell.

[0081] The display device provided by the embodiment of the present application can effectively improve the anti-peeping effect and display effect, thereby effectively improving the display quality of the display device, and ultimately increasing the favorability of customers. Improvement: The problem of low light utilization rate of traditional anti-peeping displays is improved, and the light utilization rate is improved, and the power consumption of the display is reduced.

[0082] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
