Description

Technical Field

[0001] This disclosure relates to the field of display technology, and in particular to a display device and display method. Background Technology

[0002] OLED (Organic Light-Emitting Diode) is a new generation of display technology. With its advantages such as self-illumination, high contrast, wide viewing angle, fast response, thinness and flexibility, it has shown great application potential in the display field.

[0003] In automotive OLED displays, it is usually necessary to meet the different viewing angles of the driver and passengers. Traditional split-screen displays tend to sacrifice resolution and cannot dynamically adapt to the body movements of the driver or passengers. When the body shakes significantly, crosstalk can easily occur.

[0004] Therefore, how to simultaneously satisfy the different viewing angles of different users in a single display device, achieve dynamic multi-view display without sacrificing resolution, and reduce screen crosstalk has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To address the aforementioned technical problems, this disclosure provides a display device and display method for simultaneously satisfying different viewing angles of different users within a single display device, achieving dynamic multi-view display without sacrificing resolution, and reducing screen crosstalk.

[0006] This disclosure provides a display device, including: a display panel, the display panel including a light-emitting substrate and a microlens array located on one side of the light-emitting surface of the light-emitting substrate; a visual positioning device, located on one side of the display panel along a direction parallel to the plane where the display device is located, the visual positioning device being configured to acquire binocular coordinate information of a first viewing angle and binocular coordinate information of a second viewing angle, and transmit them to a processor. The processor is configured to control the pixel emission timing in the light-emitting substrate to work in coordination with the phase modulation function of the microlens array based on the dual pupil coordinate information of the first viewpoint and the dual pupil coordinate information of the second viewpoint, thereby changing the light emission direction of the light-emitting substrate; and to control the display panel to output a first viewpoint image refracted by the microlens array to the first viewpoint, and to output a second viewpoint image diffracted by the microlens array to the second viewpoint.

[0007] Based on the same inventive concept, this disclosure provides a display method for a display device, which uses the display device as described above for display, including: a visual positioning device acquiring the dual pupil coordinate information of a first viewing angle and the dual pupil coordinate information of a second viewing angle respectively; The processor controls the pixel emission timing in the light-emitting substrate to work in coordination with the phase modulation function of the microlens array based on the dual pupil coordinate information of the first viewpoint and the dual pupil coordinate information of the second viewpoint, thereby changing the beam emission direction of the light-emitting substrate; and controls the display panel to output a first viewpoint image refracted by the microlens array to the first viewpoint, and to output a second viewpoint image diffracted by the microlens array to the second viewpoint.

[0008] The technical solution provided in this disclosure has the following advantages compared with the prior art: A display device and display method provided in this disclosure include: a display panel, the display panel including a light-emitting substrate and a microlens array located on one side of the light-emitting surface of the light-emitting substrate; a visual positioning device, located on one side of the display panel along a direction parallel to the plane of the display device, the visual positioning device being configured to acquire binocular coordinate information of a first viewing angle and binocular coordinate information of a second viewing angle, and transmit this information to a processor; a processor, the processor being configured to, based on the binocular coordinate information of the first and second viewing angles, control the pixel emission timing in the light-emitting substrate to work in coordination with the phase modulation function of the microlens array to change the light emission direction of the light-emitting substrate; and control the display panel to output a first-view image refracted by the microlens array to the first viewing angle, and to output a second-view image diffracted by the microlens array to the second viewing angle.

[0009] The system actively and in real-time tracks and acquires precise binocular coordinate information from different viewing angles using a visual positioning device. Based on this binocular coordinate information, the processor executes corresponding algorithms. The system controls the emission timing of the light-emitting substrate in conjunction with the phase modulation function of the microlens array. The timing control determines when the pixel group in the light-emitting substrate emits light, while the phase modulation controls the emission direction of the light through the microlens array. This allows the display panel to dynamically adjust the emission direction of the light according to the real-time position of the viewer from different angles. As a result, the image beam from the first viewing angle is precisely refracted by the microlens array and projected onto the user from the first viewing angle, while the image beam from the second viewing angle is precisely diffracted by the microlens array and projected onto the user from the second viewing angle. This achieves the simultaneous display of different viewing angles for different users on the same display device, enabling dynamic multi-view display without sacrificing resolution and reducing screen crosstalk.

Figure 2 The diagram shown illustrates the positional relationship between different viewing angles and the center normal of the display panel, according to an embodiment of this disclosure. Figure 3The diagram shown is a schematic representation of a film layer structure of a display panel provided in an embodiment of this disclosure; please refer to...

It may also include composite materials, such as glass-polymer composites and nanocomposite materials, and other materials such as liquid metals and hydrogels. This disclosure does not limit the material of the microlenses 41 in the display panel 100; the specific material can be set according to actual needs.

[0017] Figure 4 The diagram shown is a partial film layer schematic of a display panel provided in an embodiment of this disclosure. Please refer to it. Figure 4 The display panel 100 includes a light-emitting substrate 10 and an encapsulation layer 20. The encapsulation layer 20 is located on one side of the light-emitting surface of the light-emitting substrate 10. The light-emitting substrate 10 includes a substrate 11, a driving layer 12, and a light-emitting layer 13. The driving layer 12 includes a plurality of thin-film transistors T, and the light-emitting layer 13 includes a plurality of light-emitting elements L. The light-emitting substrate 10 includes a plurality of sub-pixels P11. Each sub-pixel P11 includes a light-emitting element L and a thin-film transistor T connected thereto. The thin-film transistor T is used to drive the light-emitting element L to emit light. The thin-film transistor T includes a gate, an active layer, a source, and a drain. The source and drain are respectively connected to the active layer. The gate can be located above, below, or on the upper or lower sides of the active layer. Figure 4 The illustration only takes the example of the gate being located above the active layer. The light-emitting element L includes an anode 32, a light-emitting functional layer 33, and a cathode 31. The anode 32 is connected to the drain of the thin-film transistor T through a via. Holes in the anode 32 and charge carriers in the cathode 31 recombine in the light-emitting functional layer 32 to achieve light emission.

[0018] The display device 200 includes a visual positioning device 00, which is a device or system that uses computer vision technology to accurately measure the spatial position and attitude of a target. It can determine the coordinates and orientation of the target in three-dimensional space through image acquisition, processing, and analysis, combined with mathematical models and algorithms. The visual positioning device 00 is configured to acquire the binocular coordinate information of a first viewing angle 01 and a second viewing angle 02, and transmit them to a processor. Optionally, the visual positioning device 00 includes a camera, a monocular camera, a binocular camera, or other devices that can be used to obtain the user's binocular coordinate information; this disclosure does not limit the specific type. Along a direction parallel to the plane of the display device 200, the visual positioning device 00 is located on one side of the display panel 100. For example, in vehicle displays, the visual positioning device is typically installed above or around the display screen, such as on the dashboard or in a rearview mirror, and is not embedded inside the display screen. Figure 1 and Figure 2 The illustration is based solely on the example of the visual positioning device 00 being located above the display panel 100. Of course, the visual positioning device 00 can also be located in other positions on the display panel 100, and this disclosure is not limited thereto.

[0019] It should be noted that the second perspective 02 mentioned in this disclosure is a different perspective from the first perspective 01. Optionally, the second perspective 02 can be located to the left, left rear, right rear, left front, right front, etc. of the first perspective 01. Figure 2 The illustration only uses the example of the second perspective 02 being located to the right of the first perspective 01, and this disclosure does not limit this. When the display device 200 provided by this disclosure is applied in an in-vehicle display, the first perspective 01 can be the driver's perspective, and the second perspective 02 can be the perspective of the front passenger or the rear passenger, and this disclosure does not limit this. Of course, the display device 200 provided by this disclosure can also be applied in other scenarios requiring privacy protection, such as home entertainment, commercial displays, ATMs, public terminals, and office workstations. The above are merely examples, and this disclosure is not limited thereto.

[0020] The display device 200 also includes a processor (not shown in the figure). Optionally, the processor may be a GPU (Graphics Processing Unit) or other types of processors, which are not limited in this disclosure. The processor is configured to control the pixel emission timing in the light-emitting substrate 10 to work in coordination with the phase modulation function of the microlens array 40 based on the binocular coordinate information of the first viewing angle 01 and the binocular coordinate information of the second viewing angle 02, thereby changing the light emission direction of the light-emitting substrate 10; and to control the display panel 100 to output a first viewing angle image refracted by the microlens array 40 to the first viewing angle 01, and to output a second viewing angle image diffracted by the microlens array 40 to the second viewing angle 02.

[0021] Specifically, traditional display technologies rely on pre-defined optical structures, typically guiding emitted light in a fixed direction. Users must be in a specific visual area to observe the image, and the screen displays the same image regardless of the viewing angle. The display device 200 provided in this disclosure integrates visual positioning, real-time light field modulation, and a microlens array 40. It can actively and in real-time track and acquire precise dual-pupil coordinate information from different viewing angles through the visual positioning device 00. Based on different dual-pupil coordinate information, the processor executes corresponding algorithms to control the pixel emission timing of the light-emitting substrate 10 and the phase modulation function of the microlens array 40. The timing control is used to determine when the pixel group in the light-emitting substrate 10 emits light, and the phase modulation controls the emission direction of the light through the microlens array 40. Through the coordination of timing control and phase modulation, the pixel group on the display panel 100 can dynamically adjust the direction of light emission according to the real-time position of the user from different viewing angles. The display device 200 can accurately project the image beam of the first viewing angle 01 to the user of the first viewing angle 01 through refraction, and at the same time accurately project the image beam of the second viewing angle 02 to the user of the second viewing angle 02 through diffraction. This achieves the simultaneous satisfaction of different viewing angles of different users on the same display device 200, realizes dynamic multi-view display without sacrificing resolution, and reduces screen crosstalk.

[0022] Furthermore, when the user is in a second perspective 02 or other positions that deviate from the first perspective 01, they can only see blurry light spots or completely different images, which helps to improve visual privacy and information security.

[0023] Thus, by setting a microlens array 40 on one side of the light-emitting surface of the display panel 100, and controlling the display panel 100 to output a first-view image refracted by the microlens array 40 to a first-viewing-angle 01, and to output a second-viewing-angle image diffracted by the microlens array 40 to a second-viewing-angle 02, parallel display of multiple users and multiple contents can be achieved on the same display device 200 without sacrificing resolution, reducing screen crosstalk, and improving visual privacy and information security.

[0024] Please refer to Figure 3 In a display device 200 provided in this disclosure, the microlens array 40 includes periodically arranged microlenses 41, and the spacing d between adjacent microlenses 41 is less than or equal to 50µm.

[0025] Optionally, the distance d between adjacent microlenses 41 can be less than or equal to 45µm, or 40µm, or 35µm, or 30µm, or 25µm, or 20µm, or 15µm, or 10µm, etc., which are not listed here. It is sufficient that the distance d between adjacent microlenses 41 is within the range of less than or equal to 50µm. When the distance d between adjacent microlenses 41 is within the range of less than or equal to 50µm, the microlens array 40 can cover most of the light emitted from the light-emitting substrate 10. Because the distance d between adjacent microlenses 41 is small, less light is not captured by the microlenses 41, thus reducing light loss. Optionally, the space between adjacent microlenses 41 may or may not be filled with a medium. Because the refractive index of the microlenses 41 is high, the light between adjacent microlenses 41 may be deflected or diffracted into the interior of the microlenses 41, which can increase the number of light captured by the microlenses 41 and further reduce light loss. The microlens array 40 refracts the captured light to the first viewing angle 01 and diffracts it to the second viewing angle 02. The distance d between adjacent microlenses 41 is less than or equal to 50µm, which is beneficial for the microlenses 41 to capture more light, reduce light leakage, ensure the brightness of the image from different viewing angles, and reduce light crosstalk.

[0026] When the distance d between adjacent microlenses 41 is greater than 50µm, the distance d is too large, reducing the number of effective modulation units per unit area, resulting in a decrease in light modulation density, a decrease in the effective resolution of the output image, and a rougher image. An excessively large gap between adjacent microlenses 41 may prevent some light emitted from the light-emitting substrate 10 from undergoing effective phase modulation, causing some light to be unable to be guided to the target viewing angle, potentially resulting in light energy loss and reduced overall display brightness. Simultaneously, unmodulated light in the gap area may be emitted in random directions, mixing into other light paths, causing image crosstalk or interference fringes on the display panel 100, leading to uneven brightness. This results in users at other viewing angles seeing image content that is not their own, making clear multi-view independent display impossible.

[0027] Thus, by setting the spacing d between adjacent microlenses 41 in the microlens array 40 to be less than or equal to 50µm, the microlens array 40 can effectively modulate the phase of the light emitted from the light-emitting substrate 10, ensuring the brightness of the image from different viewing angles and achieving clear multi-view independent display.

[0028] Figure 5 The diagram shown is a schematic representation of the overlapping relationship between a microlens and a pixel group according to an embodiment of this disclosure. Figure 6 The diagram shown illustrates another overlapping relationship between a microlens and a pixel group according to an embodiment of this disclosure; please refer to... Figure 5 and Figure 6In a display device 200 provided in this disclosure, the light-emitting substrate 10 includes an array of pixel groups P0, each microlens 41 covers a group of pixel groups P0, and the optical center of the microlens 41 coincides with the center of the pixel group P0.

[0029] Pixel group P0 includes multiple sub-pixels P11. Optionally, the sub-pixels P11 in pixel group P0 can be arranged in a traditional RGB pattern, or a diamond pattern, etc. The above are just examples, and this disclosure does not limit the arrangement of sub-pixels P11 in pixel group P0. Optionally, each pixel group P0 includes 2×2 or 4×4 sub-pixels P11. This disclosure does not limit the number of sub-pixels P11 in pixel group P0, and can be set according to actual needs. It should be noted that each microlens 41 covers a group of pixel groups P0, but is not aligned one-to-one with each sub-pixel P11. Instead, it ensures that the optical center of each microlens 41 coincides with the center of the corresponding pixel group P0, with an alignment error of less than 1µm. That is, the entire display panel 100 is formed by countless correspondingly arranged microlenses 41 and pixel groups P0, which can phase modulate the light emitted from pixel group P0 through microlenses 41, which helps to ensure the consistency of display characteristics in different areas of the display panel 100 and can reduce bright spots, dark areas or distortion caused by alignment errors.

[0030] Specifically, the optical center of the microlens 41 is the region with the best optical performance. By setting the optical center of the microlens 41 to coincide with the center of the pixel group P0, the light emitted by the pixel group P0 that needs to be modulated can be effectively captured by the microlens 41 as much as possible and subjected to precise phase modulation. The modulated light has a stronger directionality, which can reduce the possibility of light misalignment or scattering into other viewing angles caused by the misalignment of the microlens 41 and the pixel group P0, reduce light crosstalk between different viewing angles, thereby reducing optical blur or image pollution, and improving image quality and the overall light efficiency of the display device 200.

[0031] In this way, by setting the optical center of the microlens 41 to coincide with the center of the pixel group P0, the light emitted by the pixel group P0 can be captured by the microlens 41 as much as possible, thereby achieving effective phase modulation, reducing light crosstalk between different viewing angles, and improving image quality and overall light effect.

[0032] Figure 7 The diagram shown is a schematic diagram of another film layer structure of the display panel provided in this embodiment. Please refer to... Figure 3 and Figure 7 In a display device 200 provided in this disclosure, the gap between adjacent microlenses 41 is filled with a first medium 42, and the difference between the refractive index of the microlenses 41 and the refractive index of the first medium 42 is greater than or equal to 0.8.

[0033] Specifically, the display device 200 provided in this disclosure includes a display panel 100, which includes a light-emitting substrate 10 and a microlens array 40 located on one side of the light-emitting surface of the light-emitting substrate 10. In the microlens array 40, the gap between adjacent microlenses 41 is filled with a first medium 42. The refractive index of the microlens 41 is greater than the refractive index of the first medium 42, and the difference between the refractive index of the microlens 41 and the refractive index of the first medium 42 is greater than or equal to 0.8.

[0034] The surface of the microlens 41 (the interface between the lens material and the first medium 42) exhibits a significant refractive effect on light. When the difference between the refractive index of the microlens 41 and the refractive index of the first medium 42 is greater than or equal to 0.8, the strong refractive effect can more effectively capture and converge the light emitted from the pixel group P0 at a large divergence angle to the target emission direction. This reduces light loss between adjacent microlenses 41 and improves the overall light energy utilization rate from the pixel group P0 to the emitted beam. Furthermore, each microlens 41 covers a group of pixel groups P0, and the optical center of the microlens 41 coincides with the center of the pixel group P0. That is, each pixel group P0 and its corresponding microlens 41 form an optical path unit. At least part of the light from any optical path unit will be reflected or refracted at a large angle at its boundary with a high refractive index difference, thus confining the light from that optical path unit within its own optical path unit. This helps reduce crosstalk between adjacent optical path units and improves display quality.

[0035] Thus, by filling the gap between adjacent microlenses 41 with the first medium 42 and setting the difference between the refractive index of the microlens 41 and the refractive index of the first medium 42 to be greater than or equal to 0.8, the optical control capability of the microlens 41 corresponding to the pixel group P0 can be enhanced, and the optical crosstalk between adjacent pixel groups P0 or adjacent microlenses 41 can be reduced. This is beneficial to improving the display quality of the viewing angle image and realizing high brightness, high purity, low crosstalk multi-view image output.

[0036] Optionally, the surface curvature of the microlens 41 and the thickness of the microlens 41 structure can be flexibly set according to the target viewing angle required for the light to be emitted, or a suitable refractive material can be selected to achieve a wider viewing angle coverage. When the difference between the refractive index of the microlens 41 and the refractive index of the first medium 42 is greater than or equal to 0.8, the larger refractive index can ensure sufficient light deflection, allowing for a certain degree of slight deviation in the curved shape of the microlens 41, which is beneficial to reduce process alignment accuracy and improve manufacturing yield.

[0037] Please refer to Figure 3 and Figure 7 In a display device 200 provided in this disclosure, the microlens array 40 is made of one or more of titanium dioxide, silicon nitride, zinc oxide, and hafnium dioxide.

[0038] Specifically, the aforementioned materials typically have high refractive indices; for example, titanium dioxide typically has a refractive index greater than 2.4, silicon nitride has a refractive index of approximately 2.0, and so on. Microlenses 41 made of these high-refractive-index materials, combined with the low-refractive-index first medium 42 between adjacent microlenses 41, can meet the design requirement that the difference between the refractive index of the microlens 41 and the refractive index of the first medium 42 is greater than or equal to 0.8. The above is merely an example; this disclosure does not specifically limit the material of the microlens array 40. Optimization and matching can be performed based on specific system parameters, such as target viewing angle, screen size, and the refractive index of the first medium 42, to achieve the best overall performance.

[0039] The aforementioned materials exhibit excellent optical properties and good physicochemical stability in the visible light band, ensuring efficient light transmission and reducing absorption losses. They also possess high hardness, wear resistance, high temperature resistance, and aging resistance, guaranteeing the long-term reliability and performance consistency of the microlens 41 structure under long-term use and complex environments. For example, materials such as titanium dioxide and silicon nitride can be patterned using mature micro / nano fabrication technologies such as atomic layer deposition, chemical vapor deposition, and nanoimprinting, achieving extremely high surface precision. This helps ensure the uniformity and consistency of the microlens array 40, providing a reliable technological foundation for large-scale mass production.

[0040] Please continue to refer to this. Figure 3 and Figure 7 In the display device 200 provided in this disclosure, the maximum height of the microlens 41 along the thickness direction of the light-emitting substrate 10 must satisfy: h(x)=λ•Φ(x) / 2π(n-1); where λ is the wavelength of visible light; n is the refractive index of the microlens 41 material; Φ(x) is the phase modulation function, Φ(x)=k0·sin(Δθ)·x, k0 is the wave number, k0=2π / λ; the angle between the first viewing angle 01 and the center normal direction of the display panel 100 is the first angle θ1, the angle between the second viewing angle 02 and the center normal direction of the display panel 100 is the second angle θ2, Δθ is the absolute value of the difference between the first angle θ1 and the second angle θ2, and x is the abscissa of any point on the upper surface of the microlens 41 away from the light-emitting substrate 10.

[0041] Specifically, the phase modulation function Φ(x) is the optical modulation required to deflect light to two different viewing angles, θ1 and θ2, and is determined by the absolute value Δθ of the difference between the different target viewing angles. Using the above formula, the phase modulation requirement is precisely converted into the physical height that the abscissa x of each point on the surface of the microlens 41 needs to reach. Here, λ / (n-1) is determined by the operating wavelength of the microlens 41 and the material of the microlens 41, ensuring the correct conversion between optical path difference and phase difference.

[0042] The microlens array 40 is prefabricated and then mounted on top of the encapsulation layer 20 or the touch layer 30, or integrated inside the touch layer 30. For specific phase modulation requirements, the height of the microlens 41 can be preset. When the processor controls the pixel group P0 in the light-emitting substrate 10 to emit light in a specific timing sequence, the light passing through the microlens 41 with a specific height distribution can be precisely deflected to either a first viewing angle O1 or a second viewing angle O2. This ensures, from a physical height perspective, that the microlens array 40 can accurately output different images to the two preset viewing angles.

[0043] Optionally, the surface of the microlens 41 facing away from the light-emitting substrate 10 can be a convex lens, a prism, or other structures with optical modulation effects; this disclosure does not limit this. Figure 3 and Figure 7 The illustration only takes the surface of microlens 41 as a convex lens. The processor does not need to change the height or surface shape of microlens 41. It only needs to calculate the absolute value Δθ of the difference between the first included angle θ1 and the second included angle θ2 required at different viewing angles provided in real time by the visual positioning device 00, and accordingly drive the light emission timing of the corresponding pixel group P0 in the light emission substrate 10. That is, the light emission timing is precisely synchronized with the phase modulation of the fixed microlens array 40 in time, which can realize the dynamic tracking and projection of light direction.

[0044] Thus, by precisely converting the phase modulation requirement into the physical height that the horizontal coordinate x of each point on the surface of the microlens 41 needs to reach, the height distribution of the microlens array 40 can be preset in advance, and then decomposed and solidified into a processable and measurable microlens 41 surface profile, so that it matches the required phase modulation.

[0045] Please continue to refer to this. Figure 3 In a display device 200 provided in this disclosure, the display panel 100 includes an encapsulation layer 20, which covers the light-emitting surface of the light-emitting substrate 10, and a microlens array 40 is located on the side of the encapsulation layer 20 away from the light-emitting substrate 10.

[0046] In one optional embodiment provided in this disclosure, the display device 200 includes a display panel 100, which includes a light-emitting substrate 10, an encapsulation layer 20, and a microlens array 40. Along a direction perpendicular to the thickness of the light-emitting substrate 10, the microlens array 40 is located on the side of the encapsulation layer 20 facing away from the light-emitting substrate 10. The encapsulation layer 20 covers the light-emitting surface of the light-emitting substrate 10 and can be used to isolate water and oxygen, reducing aging failure of the light-emitting substrate 10 caused by moisture and oxygen intrusion. The encapsulation layer 20 can also serve as a barrier for the light-emitting substrate 10, protecting the pixels from external impacts or contamination. Positioning the microlens array 40 on the side of the encapsulation layer 20 facing away from the light-emitting substrate 10 also facilitates subsequent repairs or replacements, reducing the impact on the light-emitting substrate 10.

[0047] The encapsulation layer 20 typically includes multiple film layers, providing a flat and stable protective surface for the light-emitting substrate 10. The surface of the encapsulation layer 20 is processed to typically have excellent optical flatness, providing an ideal substrate for the fabrication and integration of the microlens array 40. Fabricating or bonding the microlens array 40 on this flat surface can improve the positional accuracy and spatial precision of each microlens 41 and reduce the positional offset of the microlens 41 caused by the unevenness of the surface of the encapsulation layer 20.

[0048] The encapsulation layer 20 typically includes inorganic materials, such as inorganic oxides, and may also include organic materials, such as transparent resins. These materials usually have a certain refractive index. The encapsulation layer 20 is located between the light-emitting surface of the light-emitting substrate 10 and the microlens array 40. It can serve as a light propagation medium with a certain refractive index, ensuring the stability and predictability of the light transmission path, which is beneficial to the overall optical design and calibration of the display panel 100.

[0049] Thus, by covering the light-emitting surface of the light-emitting substrate 10 with the encapsulation layer 20, effective protection of the light-emitting substrate 10 can be achieved; by placing the microlens array 40 on the side of the encapsulation layer 20 away from the light-emitting substrate 10, the flat surface of the encapsulation layer 20 can provide a flat base for the processing and integration of the microlens array 40, and can reduce the positional offset of the microlens array 40.

[0050] Please continue to refer to this. Figure 7 In one optional embodiment provided in this disclosure, the display panel 100 includes an encapsulation layer 20 and a touch layer 30. The encapsulation layer 20 covers the light-emitting surface of the light-emitting substrate 10 to isolate it from water and oxygen, thus ensuring the lifespan of the light-emitting substrate 10. The touch layer 30 is located on the side of the encapsulation layer 20 away from the light-emitting substrate 10. That is, the touch layer 30 can be disposed on the encapsulation layer 20 as an independent interactive functional layer. Optionally, the touch layer 30 includes touch electrodes and a touch insulating layer. The touch electrodes can be self-capacitance touch electrodes or mutual-capacitance touch electrodes, and this disclosure does not limit this. The microlens array 40 is located on the side of the touch layer 30 away from the encapsulation layer 20. That is, the microlens 41 serves as a separate optical modulation layer, independent of the touch layer 30, and does not interfere with it.

[0051] During the manufacturing process, a touch layer 30 is first integrated onto the packaged light-emitting substrate 10. At this time, the touch layer 30 can serve as a planarization substrate for the microlens array 40, facilitating the integration or bonding of the microlens array 40. By placing the touch layer 30 on the side of the microlens array 40 facing the packaging layer 20, that is, by placing the touch layer 30 at the light incident end of the microlens array 40 rather than at the light emitting end of the microlens array 40, the direct wavefront interference of the touch structure on the final modulated emitted light of the microlens array 40 can be reduced, which is beneficial to ensuring the purity of the viewing angle beam.

[0052] Optionally, to improve the visual effect, the material used to fabricate the touch electrode can be a material with high transparency and low refractive index, such as a high-precision metal mesh, silver nanowires, or a high-performance transparent compound. This disclosure does not limit the material of the touch layer 30; it can be selected according to actual needs. Using a material with good optical properties as the touch electrode can reduce the absorption and scattering of light emitted from the light-emitting substrate 10, thereby improving the optical modulation effect of the microlens array 40.

[0053] This embodiment integrates three major functions: visual positioning, microlens array 40, and touch control. The processor can provide multi-view content based on visual positioning information and receive interactive instructions from the touch layer 30, thereby realizing intelligent and contextualized human-computer interaction based on spatial perception.

[0054] Thus, by setting a display panel 100 including a touch layer 30, and with the touch layer 30 located on the side of the microlens array 40 facing the encapsulation layer 20, the touch layer 30 can be placed inside the optical path. This ensures the touch performance and display reliability of the display device 200 while achieving dynamic light control from different viewing angles and multi-view display, and provides a touch interaction experience.

[0055] Figure 8 The diagram shown is a schematic diagram of another film layer structure of the display panel provided in this embodiment. Please refer to... Figure 8 In one optional embodiment provided in this disclosure, the display panel 100 includes an encapsulation layer 20 and a touch layer 30. The encapsulation layer 20 covers the light-emitting surface of the light-emitting substrate 10. A microlens array 40 is located on the side of the encapsulation layer 20 away from the light-emitting substrate 10, and the microlens array 40 is located inside the touch layer 30. The touch layer 30 includes touch electrodes. Optionally, the microlens array 40 can be disposed on the side of the touch electrodes facing the encapsulation layer 20, and an insulating layer is used as a planarization layer on the side of the microlens array 40 away from the encapsulation layer 20, and then the touch electrodes are formed on the planarization layer to reduce the impact of unevenness on the touch effect caused by the surface of the microlens array 40.

[0056] The difference between this embodiment and the previous embodiment is that the microlens array 40 is located inside the touch layer 30. By placing the microlens array 40 inside the touch layer 30, this embodiment can reduce the physical layers and overall thickness of the display panel 100, which is beneficial for making the display device 200 thinner and lighter.

[0057] Compared to embodiments where the touch layer 30 is disposed between the encapsulation layer 20 and the microlens array 40, where an adhesive layer or air layer exists between the upper surface of the touch layer 30 and the microlens array 40, light emitted from the light-emitting substrate 10 may be reflected, scattered, or interfered at the interface of the adhesive layer or air layer. In this embodiment, the microlens array 40 is directly disposed within the touch layer 30, making it an integral part of the touch layer 30 without the need for a separate adhesive layer or air layer. This allows light emitted from the light-emitting substrate 10 to directly enter the touch layer 30 containing the microlens array 40, resulting in a simpler optical path and reduced light loss. Furthermore, disposing the microlens array 40 within the touch layer 30 reduces parallax that may occur when the touch layer 30 and the microlens array 40 are layered, due to physical gaps such as bonding layers, thus improving touch accuracy.

[0058] Thus, by integrating the microlens array 40 inside the touch layer 30, the number of film layers and the overall thickness of the display panel 100 can be reduced. It can also reduce parallax that may be caused by the bonding layer when the microlens array 40 and the touch layer 30 are set in layers, which is beneficial to improving touch accuracy and enhancing overall mechanical reliability.

[0059] Please refer to Figure 3 , Figure 7 and Figure 8 In a display device 200 provided in this disclosure, the light intensity of the light emitted from the light-emitting substrate 10 after refraction by the microlens array 40 is greater than the light intensity after diffraction by the microlens array 40.

[0060] Specifically, the light emitted from the light-emitting substrate 10 is refracted by the microlens array 40 towards the first viewing angle 01, and the light emitted from the light-emitting substrate 10 is diffracted by the microlens array 40 towards the second viewing angle 02. Refraction is a more efficient way to deflect light with less energy loss. The light intensity of the light emitted from the light-emitting substrate 10 after refraction by the microlens array 40 is relatively greater, which can reduce light energy loss and ensure that the image at the first viewing angle has sufficient brightness and contrast. Compared with refraction, diffraction may produce unnecessary stray light, causing crosstalk between images at different viewing angles. The light intensity of the light emitted from the light-emitting substrate 10 after diffraction by the microlens array 40 is relatively smaller, which can reduce light energy loss and improve the independence between images at different viewing angles.

[0061] Thus, by setting the intensity of the light emitted from the light-emitting substrate 10 to be greater than the intensity of the light diffracted by the microlens array 40, most of the light can be guided to the first viewing angle 01 of the refracted light path, which can reduce light energy loss and balance the independence between images from different viewing angles and low crosstalk.

[0062] Figure 9 The diagram shown is a flowchart illustrating a display method provided in an embodiment of this disclosure. Please refer to it. Figures 1 to 9 This disclosure provides a display method for a display device 200, which uses the display device 200 as described above for display, including: step S1, where a visual positioning device 00 acquires the binocular coordinate information of a first viewing angle 01 and a second viewing angle 02. Optionally, in some other embodiments, at least one other viewing angle different from the first viewing angle 01 and the second viewing angle 02 may be included. For example, in a vehicle display, the first viewing angle 01 is the driver's view, the second viewing angle 02 is the passenger's view, and other views are the rear passenger's view, etc. The above are just examples, and other viewing angles in other display scenarios are also possible. This disclosure does not limit this. It is understood that when multiple viewing angles exist, the visual positioning device 00 can acquire the binocular coordinate information of multiple different viewing angles respectively.

[0063] In step S2, the processor controls the pixel emission timing in the light-emitting substrate 10 to work in coordination with the phase modulation function of the microlens array 40 based on the dual pupil coordinate information of the first viewing angle 01 and the dual pupil coordinate information of the second viewing angle 02, thereby changing the beam emission direction of the light-emitting substrate 10; and controls the display panel 100 to output the first viewing angle image refracted by the microlens array 40 to the first viewing angle 01, and to output the second viewing angle image diffracted by the microlens array 40 to the second viewing angle 02.

[0064] In traditional display technologies, the screen emits light in a fixed direction, requiring the user to move to the optimal viewing area. This disclosure uses a visual positioning device 00 to acquire the binocular coordinates of the user from different viewing angles in real time, enabling the display device 200 to sense the user's position. Based on the user's binocular coordinates, the processor dynamically calculates the direction of light from each pixel group P0 and coordinates the emission timing of the pixel group P0 to match the phase modulation function of the microlens array 40, achieving directional light projection. The light emitted from the light-emitting substrate 10 can be precisely projected onto the user at different viewing angles through refraction or diffraction by the microlens array 40, rather than being uniformly scattered throughout the space, significantly reducing power consumption at the same brightness. This disclosure, by controlling the directional light from different viewing angles, isolates light from different perspectives, reducing ghosting or interference between images from different viewpoints.

[0065] Thus, the display method of the display device 200 provided in this disclosure can present personalized and dynamic content according to different viewing angles and requirements, and can provide a basis for adaptive adjustment of the content of the display device 200 and multi-user collaborative interaction.

[0066] Please continue to refer to this. Figures 1 to 9This disclosure provides a display method for a display device 200. In step S2, the display panel 100 is controlled to output a first-view image refracted by a microlens array 40 to a first-view angle 01 and a second-view image diffracted by a row of microlenses 41 to a second-view angle 02. Specifically, the processor calculates a first-view vector V1 and a first-view vector V2 based on the known coordinates of the center point or four corner points of the display panel 100, as well as the pupil coordinates of the first-view angle 01 and the pupil coordinates of the second-view angle 02. The processor also calculates a first angle θ1 between the first-view vector V1 and the center normal direction of the display panel 100, and a second angle θ2 between the second-view vector V2 and the center normal direction of the display panel 100. It can be understood that the center normal direction of the display panel 100 refers to the direction perpendicular to the plane where the display panel 100 is located, extending outward from the center of the display panel 100. When the absolute value Δθ of the difference between the first included angle θ1 and the second included angle θ2 is greater than 15°, the processor renders the same frame separately and outputs the first view image data and the second view image data to the display panel 100 for the first view 01 and the second view 02 respectively; the display panel 100 outputs the first view image refracted by the microlens array 40 to the first view 01 and outputs the second view image diffracted by the microlens array 40 to the second view 02.

[0067] In one optional embodiment provided in this disclosure, the processor obtains first binocular coordinate information P1 (x1, y1, z1) and second binocular coordinate information P2 (x2, y, 2, z2) based on the known coordinates of the center point or four corner points of the display panel 100 and the visual positioning device 00. It then calculates a first viewing angle vector V1 and a second viewing angle vector V2, where the first viewing angle vector V1 = first binocular coordinate information P1 (x1, y1, z1) - coordinates of the center point of the display panel 100, and the second viewing angle vector V2 = second binocular coordinate information P2 (x2, y, 2, z2) - coordinates of the center point of the display panel 100. A first included angle θ1 and a second included angle θ2 are calculated, where the first included angle... The second included angle The screen normal vector N of the display panel 100 is a unit vector perpendicular to the display panel 100 and pointing outwards. Understandably, the first angle θ1 represents the degree of deviation between the binocular gaze of the user in the first viewing angle 01 and the normal of the display panel 100, and the second angle θ2 represents the degree of deviation between the binocular gaze of the user in the second viewing angle 02 and the normal of the display panel 100. The absolute value Δθ of the difference between the first angle θ1 and the second angle θ2 can be used to determine whether a multi-view mode needs to be activated.

[0068] When the absolute value Δθ of the difference between the first included angle θ1 and the second included angle θ2 is less than or equal to 15°, the line of sight of the user in the first viewpoint 01 and the user in the second viewpoint 02 are relatively close, and the content of the images they are viewing has a high degree of overlap, so there is no need to render two completely different frames for the two.

[0069] When the absolute value Δθ of the difference between the first included angle θ1 and the second included angle θ2 is greater than 15°, the processor can divide the same frame into a main layer and a compensation layer, render and output them separately. It should be noted that the compensation layer is not a physically existing pixel layer, but rather an algorithm-generated image layer. It is generated through image processing algorithms such as interpolation and phase synthesis, and is used for optical compensation and content separation. Its data corresponds one-to-one with physical pixels, but the content can be dynamically adjusted according to the viewing angle. The image source for the first viewing angle 01 is the main layer output by the processor, i.e., the original RGB image. The light path for the first viewing angle 01 is refraction through the microlens array 40, displaying the first viewing angle 01 image. The image source for the second viewing angle 02 is the compensation layer output by the processor, i.e., the inverse Gamma-mapped image. The light path for the second viewing angle 02 is diffraction through the microlens array 40, displaying the second viewing angle 02 image, which differs from the first viewing angle 01 image. The compensation layer can not only adjust brightness attenuation at large viewing angles but also change image content. Inverse Gamma mapping is used to correct color shift, and together with the content separation algorithm, it achieves two independent image outputs.

[0070] In this way, the processor can render the same frame at the same time from the positions of the first viewpoint 01 and the second viewpoint 02 respectively, to obtain two completely independent image data streams, and output them synchronously to the display panel 100, so as to realize the adaptive rendering mode switching based on the viewpoint separation degree and improve the user experience.

[0071] It should be noted that the position of the microlens array 40 is fixed, and its physical structure cannot be adjusted after fabrication. The adjustment of the light deflection angle mentioned in this disclosure actually refers to the dynamic adaptation of the optical path: the processor controls the pixel emission timing and works in coordination with the phase modulation function of the microlens array 40 to change the beam emission direction. During fabrication, the surface of the microlens 41 is designed to support refraction or diffraction within a certain angle range. The processor can select the corresponding optical mode based on the absolute value of the difference between the first included angle θ1 and the second included angle θ2 calculated in real time, such as a refraction angle of 0° and a diffraction angle of 30°, or other angles. This disclosure does not limit this.

[0072] Please continue to refer to this. Figures 1 to 9This disclosure provides a display method for a display device 200. In step S2, the processor renders the same frame separately and outputs first-view image data and second-view image data to the display panel 100 for the first viewpoint 01 and the second viewpoint 02 respectively. Specifically, the processor outputs the original image data to the display panel 100 for the first viewpoint 01 and the processor outputs the compensated image data to the display panel 100 for the second viewpoint 02.

[0073] Specifically, although the first-view image and the second-view image are generated on the same display panel 100, their optical generation paths are inherently different. The light emitted from the light-emitting substrate 10 is refracted by the microlens array 40 to form the first-view image, and then diffracted by the microlens array 40 to form the second-view image. The diffraction efficiency is relatively low, the light intensity loss is large, and it may be accompanied by dispersion or stray light. As a result, under the same original image data, the second-view image may be inferior to the first-view image in terms of brightness, contrast, or color.

[0074] To address the aforementioned issues, the processor provided in this disclosure outputs raw image data for the first viewpoint 01. The optical path (refraction) corresponding to the first viewpoint 01 has high efficiency and low distortion. After the raw image data passes through this path, the expected high-quality image can be obtained. For the second viewpoint 02, it outputs compensated image data. The optical path (diffraction) corresponding to the second viewpoint 02 has lower efficiency and may have slight distortion. The second viewpoint image generated by the compensated image data can match the first viewpoint image as closely as possible in terms of brightness, contrast, etc.

[0075] The method for obtaining the compensated image data is as follows: the processor calculates the inverse gamma curve data corresponding to the original image data, applies the inverse gamma curve data to the original image, and generates image data after inverse gamma correction.

[0076] For example, the first-view image data, i.e., the original image signal, is V. in The second-view image data, i.e., the compensated image signal, is V. comp , where V comp =V in 1 / λ0 λ0 is the Gamma value, typically 2.2 or 2.4. When the absolute value Δθ of the difference between the second angle θ2 and the first angle θ1 exceeds 15°, the brightness of the second-view image is: L′=k(θ)•V comp λ0 Specifically, the actual brightness L' of the second viewing angle θ2 beam emitted from the light-emitting substrate 10 is L' = K(θ)•V λ0 The compensated brightness L output after angle attenuation by the compensation layer comp =K(θ)•(V in1 / λ0 ) λ0 =K(θ)•V in Wherein, K(θ) is the viewpoint-related correction coefficient, used to adjust the intensity of the inverse Gamma curve. It typically increases with increasing θ to compensate for brightness attenuation and color shift at large viewing angles, ultimately making the brightness of the second viewpoint 02 proportional to the brightness of the first viewpoint 01. This improves the consistency of images from different viewing angles and effectively corrects problems such as grayscale compression, loss of detail in bright or dark areas, and color saturation deviation in the second viewpoint image. Optionally, the light intensity distribution between the first viewpoint 01 and the second viewpoint 02 is 7:3; of course, other ratios are also possible, and this disclosure does not limit this.

[0077] In this way, without changing the hardware, by performing fine calibration of brightness, gamma, etc. independently on different viewing angles in the processor, the compensated second-view image can be matched with the first-view image as closely as possible in terms of brightness, contrast, etc.

[0078] The above description is merely a specific embodiment of this disclosure, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this disclosure. Therefore, this disclosure is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
