Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to an anti-glare structure of an augmented reality head-up display cover. Background Art

[0002] Head-up Display (HUD) is an auxiliary instrument used in vehicles. Drivers can see the important information they need while driving without looking down at the instrument. Nowadays, due to the convenience of HUD and its importance to driving safety, it has been used in civil aircraft, cars and other vehicles. In recent years, car manufacturers hope to improve convenience and safety by reducing the movement of driving vision. They have changed the impression that HUD is only installed on imported cars or high-end cars, and gradually installed it on light cars and small cars. The number of installations has increased significantly, reflecting the improvement of drivers' awareness of driving safety.

[0003] The Augmented Reality Head-up Display (AR HUD) is currently the latest head-up display technology that can integrate virtual images into the real environment. The AR HUD uses the car windshield as an image projection medium to display people, objects, roads, integrated warning messages and route navigation in the field of view. In addition, the AR HUD has the advantages of providing a wide virtual image display, distance sense and low power consumption through laser technology.

[0004] However, the augmented reality head-up display also faces many problems to be overcome. When the vehicle is driving, the external light is changeable, which may affect the image quality of the augmented reality head-up display due to the reflected light image, especially in high-speed driving and other dangerous driving situations, the harm of reflected light will be even greater. In addition, the high temperature generated by the infrared band of the sun will also affect the operation of the display components.

[0005] In summary, the augmented reality head-up display is easily affected by the reflected light of the sun, and the operation of the components is also easily affected by high temperature. Therefore, in view of the above problems, how to provide an augmented reality head-up display cover that can improve the reflection of sunlight, avoid glare and withstand high temperatures is still an important issue to be solved. Summary of the invention

In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0071] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense.

[0074] First see Figure 1, is an embodiment of a conventional augmented reality head-up display 1, and the conventional augmented reality head-up display 1 includes a first image generation display 11 (Picture Generation Unit, PGU), a non-adjustable free-form surface lens 12A, an adjustable free-form surface lens 12B, and a two-dimensional cover plate 13. In an embodiment of the conventional technology, the first image generation display 11 generates a first three-dimensional virtual projection light source 111. After the first three-dimensional virtual projection light source 111 is projected onto the non-adjustable free-form surface lens 12A, the first three-dimensional virtual projection light source 111 changes direction to the adjustable free-form surface lens 12B, and then the first three-dimensional virtual projection light source 111 is penetrated through the two-dimensional cover plate 13 by the adjustable free-form surface lens 12B, and finally projected onto the windshield 2, and a three-dimensional virtual image is displayed. However, during this projection process, the sunlight 3A outside the car will also penetrate through the windshield 2 and enter the car, and even reflect through the windshield 2 to the face of the driver 4, causing the driver 4's vision to be affected. On the other hand, the sunlight 3A will also enter the conventional augmented reality head-up display 1, and then be reflected by the adjustable free-form surface lens 12B and the non-adjustable free-form surface lens 12A, thereby affecting the operation of the first image generation display 11. Moreover, the high temperature and strong light of the sunlight 3A may also burn out the first image generation display 11. The longer the projection distance, the stronger the focus of the parallel sunlight entering the conventional augmented reality head-up display 1, and the higher the temperature to which the conventional augmented reality head-up display 1 is subjected, which may reach 150°C or even 200°C, but the operating temperature of the thin-film transistor (TFT) should be less than 85°C.

[0075] It is more likely to cause glare, affecting the driving safety of the driver 4. Therefore, the purpose of this application is to improve the problem that the conventional technology is prone to glare and thus affects driving safety.

[0076] See also Figure 2 In view of the above problems, the present application provides an anti-glare structure of a cover plate of an augmented reality head-up display, which includes a substrate 5, an ink layer 6A and an anti-reflective coating 6B (AR). The ink layer 6A and the anti-reflective coating 6B are sequentially stacked on the substrate 5.

[0077] In one embodiment of the present application, the constituent material of the substrate 5 includes polymethyl methacrylate (PMMA) or polycarbonate (PC). PMMA is a highly transparent, low-priced, and easily machined polymer commonly used in the manufacture of acrylic, also known as organic glass, and is currently the best polymer transparent material with a light transmittance of 92%, even higher than that of glass. It can also effectively filter out ultraviolet rays with a wavelength of less than 300 nanometers, while blocking visible light, and also has the characteristics of high temperature resistance. These special optical properties make PMMA suitable for manufacturing high-quality lenses and optical components. On the other hand, polycarbonate is a colorless, transparent, heat-resistant, impact-resistant, and highly thermoplastic polymer with good mechanical properties, good impact resistance, high refractive index, and easy processing. It can also maintain stable electrical properties in a humid or high temperature environment. Therefore, polycarbonate occupies an extremely important position in the field of optics, especially in the manufacture of automotive parts.

[0078] In one embodiment of the present application, the ink layer 6A is black and its composition includes polyester or polymethyl methacrylate. Carbon black powder is added to the ink layer 6A and is made by grinding and dispersion technology. The more carbon black powder is added in a unit, the better the light absorption ability of the ink can be. In the prior art, carbon black powder is usually combined with thermosetting resin. If UV curing resin is used, the black ink cannot be light-transmitting and cannot be cured. Carbon black powder cannot be added without limit. Therefore, in the present application, Figure 2 A structure is provided that can improve the deficiencies of the prior art. In addition to providing an ink layer 6A on the substrate 5, the present application further provides an anti-reflection coating layer 6B on the ink layer 6A.

[0079] See also Figure 2 and Figure 3 ,in Figure 3 A schematic diagram of the optical path of the first embodiment of the anti-glare structure of the augmented reality head-up display cover provided in some embodiments of the present application. Figure 2As mentioned above, in the present application, the substrate 5 is made of a colorless, transparent material with good light transmittance, and the substrate 5 includes polymethyl methacrylate or polycarbonate, and an ink layer 6A is arranged on the substrate 5, and the ink layer 6A has a light shielding function. In one embodiment of the present application, the ink layer 6A includes 1 to 10% of carbon black powder; in one embodiment of the present application, the ink layer 6A includes 5 to 10% of carbon black powder; in another embodiment of the present application, the ink layer 6A includes 1 to 20% of carbon black powder, and the content of carbon black powder in the ink layer 6A varies with the type of ink used. In addition, since the inks of different types in different embodiments have different components and proportions, it is also necessary to consider functional group reactions or physical properties at the same time, such as ultraviolet free radical reaction, thermal cross-linking reaction, ink drying speed, the proportion of carbon black powder added, leveling, optical properties, special functions (such as matte, anti-fingerprint, low reflection, etc.) or coating methods to adjust the viscosity of the ink and control operability. The present application does not limit the composition or components of the ink layer 6A.

[0080] In the present application, an ink layer 6A is provided on the substrate 5, and an anti-reflection layer coating 6B is provided on the ink layer 6A, which can increase the transmittance of light and reduce the reflectivity. In one embodiment of the present application, light penetrates along the first light path 31, respectively penetrates the anti-reflection layer coating 6B, and generates a first reflection light path 32. After penetrating the anti-reflection layer coating 6B, the first light path 31 enters the ink layer 6A. In the ink layer 6A, more than 90% of the first light path 31 can be blocked to prevent light refraction and reduce the high temperature caused by the entry of light, and at the same time form a second reflection light path 33. In one embodiment of the present application, the interface reflectivity of the augmented reality head-up display cover plate without the anti-reflection layer coating 6B on the ink layer 6A is 4.5% to 5%, and after the anti-reflection layer coating 6B is provided on the ink layer 6A, the interface reflectivity is reduced to 0.2%, wherein the calculation method of the interface refractive index is as shown in formula (1):

[0081] R=(n 1 -n 2 ) 2 / (n 1 +n 2 ) 2 Formula (1);

[0082] Where R is the interface reflectivity, n 1 and n 2 are the real refractive indexes of the two media respectively. In the present application, the media are air and the ink layer 6A, and the real refractive index of the air is 1, and the real refractive index of the ink layer 6A is 1.49 to 1.57.

[0083] See also Figure 4 , Figure 4A schematic diagram of the second embodiment of the anti-glare structure of the augmented reality head-up display cover provided in some embodiments of the present application. In this second embodiment, a shading module 6 is provided above the substrate 5, wherein the shading module 6, in addition to the ink layer 6A, is stacked in sequence above the ink layer 6A with an adhesive 6C, a wave plate 6D, a linear polarizer 6E (LinearPolarizer), an anti-glare coating 6F (Anti-glare Coating, AG), an anti-reflection coating 6B, and an anti-fingerprint coating 6G (Anti-fingerprint Coating, AF). The wave plate 6D provided above the adhesive 6C is used to adjust the polarization state of the light beam, and in one embodiment of the present application, the wave plate 6D is a quarter-phase phase difference wave plate (¼λ Retarder). The anti-glare coating 6F is coated on the linear polarizer 6E. The nanoparticles and resin composite material are combined on the surface of the anti-glare coating 6F by chemical etching or spraying, thereby changing the surface roughness of the anti-glare coating 6F, achieving a frosted effect on the surface, making the surface present diffuse reflection to reduce the reflection of light. The anti-reflection coating 6B is a combination of multiple refractive index optical layers. The anti-reflection coating 6B includes high refractive index and low refractive index components, which can increase the lens penetration and reduce the reflectivity. The anti-fingerprint coating 6G can resist oil stains and reduce dust and fingerprint residues, reduce the scattering of light, and thus affect the line of sight during driving. In one embodiment of the present application, the thickness of the ink layer 6A is 1 micron to 50 microns; in one embodiment of the present application, the thickness of the anti-reflective coating 6B is 10 nanometers to 100 microns; in one embodiment of the present application, the thickness of the wave plate 6D is 107 nanometers to 195 nanometers; in one embodiment of the present application, the thickness of the linear polarizer 6E is 5 microns to 148 microns; in one embodiment of the present application, the thickness of the anti-glare coating 6F is 5 microns to 20 microns; in one embodiment of the present application, the anti-fingerprint coating 6G is between 0 microns and 5 microns.

[0084] See also Figure 5 , Figure 5 A schematic diagram of the optical path of the second embodiment of the anti-glare structure of the augmented reality head-up display cover provided in some embodiments of the present application. In the present application, an ink layer 6A, an adhesive 6C, a wave plate 6D, a linear polarizer 6E, an anti-glare coating 6F, an anti-reflection coating 6B and an anti-fingerprint coating 6G are sequentially stacked on the substrate 5. Figure 5In the embodiment, the light penetrates according to the second optical path 34, first passes through the anti-fingerprint coating 6G, and then enters the anti-reflection coating 6B. In this process, since the anti-reflection coating 6B has the characteristic of increasing the light transmittance, the reflectivity of the light is reduced. Then the light enters the anti-glare coating 6F. Since the surface of the anti-glare coating 6F is coated with a composite material of nanoparticles and resin, its surface is rough, and the surface reflected light presents diffuse reflection. The second optical path 34 then generates multiple third reflection optical paths 35A, 35B, and 35C. Then the light passes through the linear polarizer 6E and enters the wave plate 6D. The linear polarization can filter the light into linear Polarized light converts the light passing through the wave plate 6D into right-handed circularly polarized light 61, which penetrates the adhesive 6C and enters the ink layer 6A. Since the ink layer 6A can block more than 90% of the light entering and prevent the light from being refracted, the light will be reflected on the surface of the ink layer 6A as left-handed circularly polarized light 62. Since it is orthogonal to the original linearly polarized light, it cannot be reflected, thereby reducing the reflected light and avoiding the driver's vision being affected by light scattering. At the same time, the characteristics of the ink layer 6A also absorb the light, reducing the high temperature caused by the entry of light, and preventing the augmented reality head-up display from being damaged or malfunctioning due to high temperature.

[0085] In one embodiment of the present application, the wave plate 6D has a shielding rate greater than 40%, so the incident light cannot pass through after reflection. Since the ink layer 6A can block the light from entering the augmented reality head-up display, when the light is not focused, the high temperature only appears on the surface of the ink layer 6A, so that the internal temperature of the augmented reality head-up display will not be affected by the high heat of the light, and even the display in the augmented reality head-up display can be maintained at less than 85°C and operate normally.

[0086] In one embodiment of the present application, after the ink layer 6A on the substrate 5 is sequentially laminated with adhesive 6C, wave plate 6D, linear polarizer 6E, anti-glare coating 6F, anti-reflection coating 6B and anti-fingerprint coating 6G, the interface reflectivity is measured by a spectrophotometer and is less than 0.2%, which is the highest anti-reflectivity specification that can be mass-produced on the market. The gloss (Gloss) measured by a gloss meter at an angle of 85° is less than 5 gloss units (GU); the water drop angle (Contact Angle) measured by a water contact angle meter is greater than 110°, confirming that the augmented reality head-up display cover provided by the present application does have the characteristics of low reflection and low glare.

[0087] See also Figure 6 , Figure 6A schematic diagram of the structure of the third embodiment of the anti-glare structure of the augmented reality head-up display cover provided by some embodiments of the present application. In one embodiment of the present application, the substrate 5 is a triangular prism with a three-dimensional structure. In one embodiment of the present application, a plurality of substrates 5 are provided, each substrate 5 is provided with a shading module 6 on its surface, and the distance between each adjacent shading module 6 is 1 mm. In one embodiment of the present application, the thickness of the substrate 5 is 1 mm to 3 mm, and the height is 0.3 mm to 2 mm. In one embodiment of the present application, the augmented reality head-up display cover provided by some embodiments of the present application is formed by multiple substrates 5 and a shading module 6 arranged above the substrate 5, and multiple substrates 5 and shading modules 6 are symmetrically arranged under each substrate 5, so that the second three-dimensional virtual projection light source 71 generated by the second image generating display 7 can pass through the substrate 5 located in the lower layer, enter the substrate 5 located in the upper layer, and refract the second three-dimensional virtual projection light source 71 along the shading module 6. On the other hand, the sunlight 3A will be irradiated on the shading module 6 and absorbed, reducing the refraction of the second three-dimensional virtual projection light source 71, and also reducing the reflectivity of the sunlight 3A, thereby improving the projection effect of the second image generating display 7 and reducing the occurrence of the situation where the sunlight 3A affects the line of sight during driving.

[0088] In view of this, the anti-glare structure of the augmented reality head-up display cover provided by the present application not only solves the problems that the previous augmented reality head-up display is easily affected by light and the components are easily damaged due to high temperature, but also has the advantages of low reflectivity, low glare, and can reduce the temperature of direct light, and reduce the occurrence of situations where light affects the line of sight during driving.
