[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art based on the present application belong to the scope protected by the present application.

[0029] As Figure 1 shown, the present application provides a display screen, including:

[0030] A light-emitting substrate 110, a first lens 120, and a retroreflective film 130; a semi-reflective and semi-transmissive film is disposed on the first lens 120;

[0031] The light emitted by the light-emitting substrate 110 irradiates onto the first lens;

[0032] The first lens is used to reflect a part of the light emitted by the light-emitting substrate 110 to the retroreflective film 130, and transmit another part of the light emitted by the light-emitting substrate 110 to the first user visual observation area;

[0033] The retroreflective film 130 is used to reverse the light reflected by the first lens to the first lens 120, transmit it through the first lens 120 to a first object, and reflect the light to a second user visual observation area after passing through the first object.

[0034] The light-emitting substrate is used to emit light, and the first lens is an object that can transmit light. Exemplarily, the first lens can be a plane mirror or a concave lens.

[0035] The semi-reflective and semi-transmissive film is a special optical film that can simultaneously achieve the reflection and transmission of part of the light. The semi-reflective and semi-transmissive film can be divided into metal films and dielectric films. When the semi-reflective and semi-transmissive film is a metal film, the material of the semi-reflective and semi-transmissive film can be silver (Ag), aluminum (Al), chromium (Cr), or gold (Au). When the semi-reflective and semi-transmissive film is a dielectric film, the material of the semi-reflective and semi-transmissive film can be TiO2 (TiO2), NbOx (niobium oxide), and SiO2 (silicon dioxide), etc.

[0036] The semi-reflective and semi-transmissive film, through material design (such as film thickness, multi-layer structure, nano-pore channels, etc.), utilizes the interference effect of light (dielectric film) or the free electron oscillation on the metal surface (metal film) to allow part of the energy (light, electromagnetic wave) or substance (molecule, ion) to pass through, while reflecting or blocking the other part.

[0037] In one example, the semi-reflective and semi-transmissive film is a dielectric film. The semi-reflective and semi-transmissive film can be formed by stacking multiple dielectric layers. For example, the semi-reflective and semi-transmissive film is formed by stacking TiO2 (titanium dioxide), NbOx (niobium oxide), and SiO2 (silicon dioxide). The refractive indices of adjacent dielectric layers are different. By adjusting the refractive index and thickness of the dielectric layer, different ratios of reflectivity to transmittance can be achieved.

[0038] In one example, the ratio of reflectivity to transmittance of the semi-reflective and semi-transmissive film is 1:1, that is, the semi-reflective and semi-transmissive film can reflect light while transmitting light.

[0039] The semi-reflective and semi-transmissive film can be attached to the first lens through a bonding technique or coated on the first lens through a coating technique. The specific process used is not limited here. In one example, the semi-reflective and semi-transmissive film is coated on the first lens through a coating technique.

[0040] The first lens is located in the direction of the light emitted by the light-emitting substrate. Because the first lens is provided with a semi-reflective and semi-transmissive film, part of the light emitted by the light-emitting substrate can pass through the first lens, and the other part can be reflected by the second lens.

[0041] The retroreflective film is a special optical material that can reflect the incident light back to the light source direction along the original path.

[0042] The retroreflective film is designed through special microstructures (such as micro-prisms, glass microspheres). After the light undergoes multiple refractions and reflections on the surface of the retroreflective film, it returns along the incident direction, forming a strong "directional reflection" effect.

[0043] When the retroreflective film adopts a micro-prism structure, the geometric optical properties of the micro-prism array (such as cube-corner prism) are utilized to make the light totally internally reflected in the prism and then return along the original path.

[0044] When the retroreflective film adopts a glass microsphere structure, after the light enters the transparent microsphere, it undergoes refraction, internal surface reflection, and then refraction, and finally returns to the light source direction.

[0045] When the retroreflective film adopts a micro-prism structure, the material of the retroreflective film can be: polycarbonate (PC), polymethyl methacrylate (PMMA), polyethylene terephthalate (PET) film. The surface structure of the retroreflective film can be a cube-corner prism array formed by precision imprinting or injection molding.

[0046] When the retroreflective film adopts a glass microsphere structure, the materials of the retroreflective film can be: polyvinyl chloride (PVC), PET, fabric, etc. The core structure of the retroreflective film can be that high refractive index glass microspheres are embedded on the surface, for example, the refractive index is 1.9 - 2.4. Aluminum can be plated or a white reflective layer can be coated behind the glass microspheres.

[0047] The retroreflective film can also include a microprism structure and a glass microsphere structure, which can be specifically determined based on the actual situation and are not limited here.

[0048] The retroreflective film is arranged facing the display substrate and the first lens. The light reflected by the first lens irradiates onto the retroreflective film, and the light is reversed through the retroreflective film.

[0049] That is to say, after the light emitted by the light-emitting substrate irradiates onto the first lens, because a half-reflective and half-transmissive film is provided on the first lens, under the action of the half-reflective and half-transmissive film, a part of the light emitted by the light-emitting substrate is reflected, and a part directly passes through. The light that passes through can be transmitted to the first user visual observation area, and the user can view the content displayed on the light-emitting substrate in the first user visual observation area.

[0050] In addition, the light reflected by the half-reflective and half-transmissive film irradiates onto the retroreflective film. Under the action of the retroreflective film, the retroreflective film reflects the light reflected by the first lens back to the first lens along the original path. After the reflection of the half-reflective and half-transmissive film and the reflection of the retroreflective film, the light emitted by the light-emitting substrate but passing through the first lens is transmitted onto the first object. The first object is an object that can reflect light, and the first object reflects the light to the second user visual observation area, and the user can view the content displayed on the light-emitting substrate in the second user visual observation area.

[0051] After the reflection of the half-reflective and half-transmissive film and the reflection of the retroreflective film, and finally the light passing through the half-reflective and half-transmissive film is transmitted onto the first object. After the reflection of the first object, an image can be formed in the second user visual observation area. Under the action of the half-reflective and half-transmissive film, the retroreflective film and the first object, the user can not only view the content displayed on the light-emitting substrate in the first user visual observation area, but also view the content displayed on the light-emitting substrate in the second user visual observation area.

[0052] In an example, a 45° angle is formed between the light-emitting substrate 110 and the first lens 120, and the ratio of the reflectivity to the transmittance of the half-reflective and half-transmissive film is 1:1. Because a 45° angle is formed between the light-emitting substrate 110 and the first lens 120, after the light emitted by the light-emitting substrate 110 irradiates onto the half-reflective and half-transmissive film, a part passes through the half-reflective and half-transmissive film and propagates in the original direction, and the other part is reflected by the half-reflective and half-transmissive film, and the optical path changes and is transmitted in the direction towards the retroreflective film 130.

[0053] The reflectivity and transmittance of the semi-reflective semi-transmissive film to light can both be set to 50%, so that the light energy loss after one-time transmission and one-time reflection of light through the semi-reflective semi-transmissive film can be minimized, and the brightness of the light finally observed by the human eye can be improved.

[0054] The display screen of the present application can be applied to a display device that can image the image output by the image source on the wearer's human eye. The display device can be a product applied in the fields of military, medical, aerospace, education, industrial production, entertainment, etc. In addition, the display screen can also be applied in the automotive field.

[0055] In a possible implementation manner, the display screen is a vehicle-mounted display screen, the first user visual observation area is the visual observation area in the direction of the vehicle-mounted display screen, the second user visual observation area is the visual observation area in the direction of the windshield, and the first object is the windshield.

[0056] The display screen is a vehicle-mounted display screen, and the content that the vehicle-mounted display screen can display includes: vehicle information, navigation information, multimedia entertainment information, etc. When the display screen is a vehicle-mounted display screen, the first user visual observation area is the visual observation area in the direction of the vehicle-mounted display screen, and the second user visual observation area is the visual observation area in the direction of the windshield.

[0057] That is to say, when the display screen is a vehicle-mounted display screen, the light emitted by the light-emitting substrate irradiates the first lens. Because the semi-reflective semi-transmissive film is provided on the first lens, under the action of the semi-reflective semi-transmissive film, a part of the light emitted by the light-emitting substrate is reflected, and a part directly passes through. The light that passes through can be transmitted to the visual observation area in the direction of the vehicle-mounted display screen, and the driver can look down at the content displayed on the vehicle-mounted display screen in the visual observation area in the direction of the vehicle-mounted display screen.

[0058] In addition, the light reflected by the semi-reflective semi-transmissive film irradiates the retroreflective film. Under the action of the retroreflective film, the retroreflective film reflects the light reflected by the first lens back to the first lens along the original path. After the light is reflected by the semi-reflective semi-transmissive film and the retroreflective film, the light emitted by the light-emitting substrate but passing through the first lens is transmitted to the windshield, and the windshield reflects the light to the visual observation area in the direction of the windshield. The driver can also directly view the content displayed on the vehicle-mounted display screen in the virtual image formed in the visual observation area in the direction of the windshield without lowering the head. Under the action of the windshield reflection, reducing the backflow of sunlight helps to extend the service life of the vehicle-mounted display screen. Because a virtual image is formed, the driver can not only view the content displayed on the vehicle-mounted display screen without lowering the head, but also helps the driver reduce visual fatigue caused by near and far focus switching, ensuring driving safety.

[0059] In addition, through the ingenious combination design of the retroreflective film, the semi-reflective and semi-transmissive film, and the windshield, the in-vehicle display screen of the present application can achieve a small volume. A smaller in-vehicle display screen helps vehicle manufacturers promote the installation of HUD (Head Up Display), and has good application prospects.

[0060] In a possible implementation manner, the light-emitting substrate 110, the first lens 120, and the retroreflective film 130 are arranged in a triangle.

[0061] As Figure 2 shown, the light-emitting substrate 110, the first lens 120, and the retroreflective film 130 are arranged in a triangle, and the cross-sectional view of the display screen composed of the light-emitting substrate 110, the first lens 120, and the retroreflective film 130 is a triangle.

[0062] The light-emitting substrate 110 is arranged facing the first lens 120 and the retroreflective film 130, the first lens 120 is arranged facing the light-emitting substrate 110 and the retroreflective film 130, and the retroreflective film 130 is arranged facing the light-emitting substrate 110 and the first lens 120. In this way, the light emitted by the light-emitting substrate can irradiate the first lens. After that, because a semi-reflective and semi-transmissive film is provided on the first lens, under the action of the semi-reflective and semi-transmissive film, part of the light emitted by the light-emitting substrate is reflected and part directly passes through.

[0063] In addition, the light reflected by the semi-reflective and semi-transmissive film can also irradiate the retroreflective film. Under the action of the retroreflective film, the retroreflective film reflects the light reflected by the first lens back to the first lens along the original path. After the light is reflected by the semi-reflective and semi-transmissive film and the retroreflective film, the light emitted by the light-emitting substrate but passing through the first lens is transmitted to the first object. The first object is an object that can reflect light, and the first object reflects the light to the second user visual observation area, and the user can view the content displayed on the light-emitting substrate in the second user visual observation area.

[0064] In a possible implementation manner, the included angle between the first lens 120 and the light-emitting substrate 110 is an acute angle.

[0065] When the included angle between the first lens 120 and the light-emitting substrate 110 is an acute angle, the light emitted by the light-emitting substrate 110 can irradiate the first lens. After that, because a semi-reflective and semi-transmissive film is provided on the first lens, under the action of the semi-reflective and semi-transmissive film, part of the light emitted by the light-emitting substrate is reflected and part directly passes through.

[0066] In a possible implementation manner, the included angle between the first lens 120 and the light-emitting substrate 110 is a right angle.

[0067] When the included angle between the first lens 120 and the light-emitting substrate 110 is a right angle, the light emitted by the light-emitting substrate 110 can irradiate the first lens. Then, because a semi-reflective and semi-transmissive film is provided on the first lens, under the action of the semi-reflective and semi-transmissive film, part of the light emitted by the light-emitting substrate is reflected and part directly passes through.

[0068] In a possible implementation manner, the included angle between the first lens 120 and the retroreflective film 130 is an acute angle.

[0069] When the included angle between the first lens 120 and the retroreflective film 130 is an acute angle, the light reflected by the second lens can irradiate the retroreflective film 130 more. Compared with the case where the included angle between the first lens 120 and the retroreflective film 130 is a right angle or an obtuse angle, when the included angle between the first lens 120 and the retroreflective film 130 is an acute angle, the light reflected by the second lens can be returned to the first lens 120 along the original path more, so that more light passes through the first lens 120, more light is transmitted to the first object, and after the first object reflects the light to the second user's visual observation area, the imaging in the second user's visual observation area is clearer, improving the display effect.

[0070] In a possible implementation manner, the included angle between the light-emitting substrate 110 and the retroreflective film 130 is 90°.

[0071] The included angle between the light-emitting substrate 110 and the retroreflective film 130 can also be 90°. In this way, the light emitted by the light-emitting substrate can irradiate the first lens. Then, because a semi-reflective and semi-transmissive film is provided on the first lens, under the action of the semi-reflective and semi-transmissive film, part of the light emitted by the light-emitting substrate is reflected and part directly passes through.

[0072] In addition, the light reflected by the semi-reflective and semi-transmissive film can also irradiate the retroreflective film. Under the action of the retroreflective film, the retroreflective film reflects the light reflected by the first lens back to the first lens along the original path. After the light is reflected by the semi-reflective and semi-transmissive film and the retroreflective film, the light emitted by the light-emitting substrate but passing through the first lens is transmitted to the first object. The first object is an object that can reflect light, and the first object reflects the light to the second user's visual observation area, and the user can view the content displayed on the light-emitting substrate in the second user's visual observation area.

[0073] In a possible implementation manner, the semi-reflective and semi-transmissive film is provided on the side of the first lens 120 close to the light-emitting substrate 110.

[0074] The light can be projected first through the action of the semi-reflective and semi-transmissive film and then projected to the corresponding visual observation area through the first lens.

[0075] In a possible implementation, the first lens 120 is a concave lens.

[0076] A concave lens is also a diverging lens, which is a lens with a thinner middle and thicker edges. It can make the incident parallel light diverge outward after refraction, and the reverse extension lines of the light converge at the virtual focus. When the first lens 120 is a concave lens, the light is refracted towards its converging focus and forms an image in the corresponding area.

[0077] In a possible implementation, the first lens 120 is a plane mirror.

[0078] A plane mirror can transmit light, enabling the light to be transmitted to the corresponding visual observation area.

[0079] As Figure 3 shown, the present application also provides a vehicle, including the display screen and the windshield described in any one of the above.

[0080] The display screen is an in-vehicle display screen. The content that the in-vehicle display screen can display includes: vehicle information, navigation information, multimedia entertainment information, etc. When the display screen is an in-vehicle display screen, the first user visual observation area is the visual observation area in the direction of the in-vehicle display screen, and the second user visual observation area is the visual observation area in the direction of the windshield.

[0081] That is to say, when the display screen is an in-vehicle display screen, after the light emitted by the light-emitting substrate irradiates the first lens, because a semi-reflective and semi-transmissive film is provided on the first lens, under the action of the semi-reflective and semi-transmissive film, part of the light emitted by the light-emitting substrate is reflected and part directly passes through. The light that passes through can be transmitted to the first user visual observation area, and the driver can look down at the content displayed on the in-vehicle display screen in the visual observation area in the direction of the in-vehicle display screen.

[0082] In addition, the light reflected by the semi-reflective and semi-transmissive film irradiates the retroreflective film. Under the action of the retroreflective film, the retroreflective film reflects the light reflected by the first lens back to the first lens along the original path. After the light is reflected by the semi-reflective and semi-transmissive film and the retroreflective film, the light emitted by the light-emitting substrate but passing through the first lens is transmitted to the windshield, and the windshield reflects the light to the visual observation area in the direction of the windshield. The light reflected by the windshield finally converges to the human eye. Since the light is emitted from the virtual image P', the human eye receives the virtual image of point P. The driver can also view the content displayed on the in-vehicle display screen directly at the virtual image formed in the visual observation area in the direction of the windshield without lowering the head. Under the reflection of the windshield, a virtual image is formed, and the driver can view the content displayed on the in-vehicle display screen without lowering the head, ensuring driving safety.

[0083] As Figure 3As shown, there is a light source point P in the light-emitting substrate 110. That is to say, light rays emit from point P of the light-emitting substrate 110. This light source point P can be a pixel point on the display screen, and the light source point P can emit light of a specific color and a specific intensity. Specifically, it can be determined based on the actual situation.

[0084] The light emitted from the light source point P first encounters the first lens 120. A semi-reflective and semi-transmissive film is provided on the first lens 120, and the first lens 120 can be a concave lens. The shape of the concave lens causes the light rays to refract towards its converging focal point. The function of the semi-reflective and semi-transmissive film is to divide the incident light into two parts, one part is reflected and the other part is transmitted. That is, under the action of the semi-reflective and semi-transmissive film, the light rays emitted from the light source point P on the light-emitting substrate to the semi-reflective and semi-transmissive film, one part of the light rays is reflected and one part of the light rays directly passes through.

[0085] The light rays reflected by the first lens 120 then pass through the retroreflective film 130. The function of the retroreflective film 130 is to reverse the direction of the light rays so that they propagate along a substantially opposite direction. The light rays retroreflected by the retroreflective film 130 encounter the first lens 120 again, and the first lens 120 converges the light rays again. Under the action of the semi-reflective and semi-transmissive film on the first lens 120, a part of the light rays will be transmitted. The transmitted light rays leave the first lens 120 and continue to propagate along their path until the light rays then hit the windshield of the vehicle. The windshield serves as a reflecting surface to reflect the light rays, and the light rays reflected by the windshield finally converge onto the human eye. Since the light rays emit from the virtual image P', the human eye receives the virtual image of point P. This means that the image seen by the human eye is formed at a certain position behind point P, rather than the actual physical position.

[0086] The driver can also directly view the content displayed on the in-vehicle display screen at the virtual image formed at point P' without lowering the head. Under the reflection of the windshield, a virtual image is formed, and the driver can view the content displayed on the in-vehicle display screen without lowering the head, ensuring driving safety.

[0087] As Figure 4 shown, θ is the included angle between the light-emitting substrate 110 and the retroreflective film 130. In order to reduce stray light, the included angle θ between the light-emitting substrate 110 and the retroreflective film 130 can be selected as 60° to 90°.

[0088] It should be noted that in this text, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising said element.
