Description

Technical Field

[0001] This application relates to the field of display technology, specifically to a method for atomizing a mirror display device. Background Technology

[0002] Current mirror-based display devices consist of a mirror glass, an LCD glass, and a backlight module. Light is emitted from the backlight module, passes through the LCD glass and the mirror glass sequentially, and reaches the user's eyes. A hollow layer exists between the LCD glass and the mirror glass, forming a sandwich-like structure. However, due to the high reflectivity of the mirror glass, most of the light passes through it after reaching it; a small portion is reflected back to the LCD glass, resulting in secondary reflection. If the image (light) displayed by the backlight module enters the hollow layer and is reflected multiple times, a stable image, or ghosting, will form. When the mirror glass is deformed or comes into contact with the LCD glass, interference fringes can easily form.

[0003] Ghosting and interference fringes can severely affect the display effect, so it is necessary to reduce or weaken ghosting and interference fringes. Summary of the Invention

[0014] Based on any one of the first to fifth implementations of the embodiments of this application, in the sixth implementation of the first aspect of the embodiments of this application, the first atomizing layer includes no more than two layers of cavity powder.

[0015] Based on any one of the first to sixth implementations of the embodiments of this application, in the seventh implementation of the first aspect of this application, before the first mixture of the cavity powder and the dispersion is obtained, the method further includes:

[0016] Cavity powders can be prepared using either the template method or the sol-gel method.

[0017] Based on any one of the first to seventh implementations of the embodiments of this application, in the eighth implementation of the first aspect of this application, the cavity powder material includes silicon dioxide or polymer material.

[0018] Based on any one of the first to eighth implementations of the embodiments of this application, in the ninth implementation of the first aspect of this application, the polymer material includes polycarbonate (PC) resin, polymethyl methacrylate (PMMA) or polystyrene (PS).

[0019] Based on any one of the first to ninth implementations of the embodiments of this application, in the tenth implementation of the first aspect of the embodiments of this application, the step of attaching the first mixture to the first surface of the mirror glass of the mirror display device includes the following steps:

[0020] The first mixture is placed in a spraying machine, and the spraying machine is used to evenly spray the first mixture onto the first surface of the mirror glass. Then the mirror glass with the first mixture attached is fixed.

[0021] or,

[0022] The first mixture is placed in a roller mill, and the roller mill is used to evenly coat the first mixture onto the first surface of the mirror glass, thereby fixing the mirror glass after the first mixture is attached.

[0023] Furthermore, a first mixture is attached to the first surface of the mirror glass of the mirror display device to obtain a first atomized layer, specifically including:

[0024] The first mixture is attached to a PET film and then fixed to form a frosted PET film. The frosted PET film is then pasted onto the first side of the mirror glass, and the frosted PET film pasted onto the mirror glass serves as the first frosting layer.

[0025] Furthermore, the haze of the atomized mirror glass is 20%-40%, the gloss is 60%-80%, the reflectivity is 60%-80%, and the roughness is 0.03-0.12.

[0026] The second aspect of this application provides a mirror display device using the atomization processing method described in any of the above claims, which includes a mirror glass, a liquid crystal glass, and a backlight module. The side of the mirror glass facing the liquid crystal glass is the first surface of the mirror glass, and a first atomization layer is provided on the first surface of the mirror glass. The first atomization layer contains cavity powder.

[0027] There is a hollow layer between the mirror glass and the liquid crystal glass;

[0028] The light emitted by the backlight module passes sequentially through the liquid crystal glass, the hollow layer, and the mirror glass.

[0029] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:

[0030] In this application, a first mixture of cavity powder and dispersion liquid is used. This first mixture is then adhered to the first surface of a mirror glass to complete the atomization treatment of the first surface of the mirror glass, resulting in a first atomized layer. Because a first atomized layer is formed on the first surface of the mirror glass, the light emitted from the backlight module sequentially passes through the liquid crystal glass, the cavity layer, the first atomized layer, and the mirror glass. Compared to existing technologies where light enters the mirror glass directly from the cavity layer, in this application, the light first enters the first atomized layer from the cavity layer, and then enters the mirror glass from the first atomized layer. When the light reaches the first atomized layer, the cavity powder in the first atomized layer can disrupt the light path through diffuse reflection, causing ghosting or interference fringes to be unstable in imaging. Simultaneously, the cavity powder has a cavity structure, utilizing the multifaceted and resonant properties of the cavity structure to reflect and consume the light multiple times, reducing the energy and brightness of ghosting and interference fringes.

[0040] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0041] like Figure 6 As shown, this application provides a method for frosting a mirror display device, including steps 601 to 603:

[0042] 601. Mix the cavity powder and the dispersion to obtain the first mixture;

[0043] Cavity powder refers to tiny particles with internal cavities. The dispersion can be an organic liquid, an inorganic liquid, or a mixture of organic and inorganic substances. In this embodiment, a mixed solution of silicate ester, polyethylene glycol, and ethanol is preferred, or an acrylic resin can be used directly. The first mixture is a suspension. The ratio of cavity powder to dispersion is determined based on the atomization degree, thickness, and adhesion method of the first atomized layer, and is not specifically limited.

[0044] 602. A first mixed liquid is attached to the first surface of the mirror glass of the mirror display device to obtain a first atomized layer;

[0045] The first side of the mirrored glass can also be called the back side of the mirrored glass. In general use, the side of the mirrored glass facing the user is the front side, while the first side is the side away from the user. A first mixture is applied to the first side of the mirrored glass to form a first atomized layer. The refractive index of the first atomized layer is greater than that of air, but smaller than that of the mirrored glass. Here, the refractive index refers to the absolute refractive index relative to a vacuum. The mirrored glass can be made of glass or PET material.

[0046] 603. Assemble the mirror glass, liquid crystal glass and backlight module, with a hollow layer between the mirror glass and the liquid crystal glass, the mirror glass and the backlight module being disposed on both sides of the liquid crystal glass, and the first surface of the mirror glass facing the liquid crystal glass.

[0047] A mirror display device is assembled from a mirror glass, an LCD glass, and a backlight module. A gap, or hollow layer, exists between the mirror glass and the LCD glass. The front of the LCD glass faces the back of the mirror glass, and the back of the LCD glass faces the backlight module. Therefore, the light emitted from the backlight module passes sequentially through the LCD glass, the hollow layer, the first frosting layer, and the mirror glass before reaching the user's eyes.

[0048] In this application, a first mixture of cavity powder and dispersion liquid is used. This first mixture is then adhered to the first surface of a mirror glass to complete the atomization treatment of the first surface of the mirror glass, resulting in a first atomized layer. Because a first atomized layer is formed on the first surface of the mirror glass, the light emitted from the backlight module sequentially passes through the liquid crystal glass, the cavity layer, the first atomized layer, and the mirror glass. Compared to existing technologies where light enters the mirror glass directly from the cavity layer, in this application, the light first enters the first atomized layer from the cavity layer and then enters the mirror glass from the first atomized layer. When the light reaches the first atomized layer, the cavity powder in the first atomized layer can disrupt the light path through diffuse reflection, causing ghosting or interference fringes to be unstable in imaging. Simultaneously, the cavity powder has a cavity structure, utilizing the multifaceted and resonant properties of the cavity structure to reflect and consume the light multiple times, reducing the energy and brightness of ghosting and interference fringes.

[0049] By setting a first frosting layer on the first surface of the mirror glass, not only can ghosting be reduced or weakened, but interference fringes can also be reduced or weakened. The generation of interference fringes is also related to the multiple reflections of light between the liquid crystal glass and the mirror glass. Because the distance between the mirror glass and the liquid crystal glass is very small, the cavity is prone to deformation, and the liquid crystal glass and mirror glass may even come into contact, causing interference and resulting in interference fringes. Therefore, reducing the multiple reflections of light in the glass reduces interference fringes and improves the display effect.

[0050] The product requires the mirrored glass to have a mirror effect, meaning it needs a high reflectivity. Increasing the overall light transmittance of the mirrored glass will worsen the reflection effect. Reducing the distance between the liquid crystal glass and the mirrored glass can easily cause deformation of the cavity, or even contact between the two, resulting in interference fringes (Newton's rings). Using high-haze liquid crystal glass only disrupts the light reflected from the liquid crystal glass, but does not disrupt most of the light reflected from the mirrored glass, thus having a limited effect on alleviating ghosting. This application performs a haze treatment on the back of the mirrored glass. Without affecting the reflection effect of the front of the mirrored glass, it disperses and dissipates the light reflected back to the liquid crystal glass from the back of the mirrored glass, which is the main source of ghosting and interference, preventing the light from forming a stable image and solving problems such as ghosting and interference fringes. In particular, it can improve the display effect of interactive display products (frame-mounted, zero-mounted, and full-mounted) with touch panels (TP), improving product quality.

[0051] Compared to existing technologies that perform AG treatment on the front of the LCD glass, this application performs frosting treatment on the back of the mirror glass, which can more effectively reduce reflection between the mirror glass and the LCD glass and significantly improve the display effect.

[0052] In one implementation of this application, the diameter of the outer sphere of the cavity powder is 0.03 micrometers to 0.12 micrometers.

[0053] The particle size of the cavity powder is described by the diameter of its circumscribed sphere, which is greater than or equal to 0.03 micrometers and less than or equal to 0.12 micrometers. When the mirror display device is installed in a mobile phone, the circumscribed sphere diameter of the cavity powder ranges from 0.03 micrometers to 0.06 micrometers; when the mirror display device is installed in a vehicle, the circumscribed sphere diameter ranges from 0.06 micrometers to 0.12 micrometers; and when the mirror display device is installed in an advertising machine, the circumscribed sphere diameter ranges from 0.06 micrometers to 0.09 micrometers.

[0054] The diameter of the outer sphere of the cavity powder can also be selected from other ranges, without any specific limitation.

[0055] In one implementation of this application, the cavity powder includes an arc-shaped hollow microstructure. The arc-shaped hollow microstructure is a tiny structure with an internal cavity. It has at least one inner arc-shaped surface and at least one outer arc-shaped surface. Because the arc-shaped hollow microstructure has an arc surface, it can reflect and refract light in multiple directions, partially disrupting the light and reducing the amount of light directly reflected to the liquid crystal glass. Specifically, the normal direction at each point of the arc surface is different, resulting in a different reflection angle at each point. Designing the microstructure as an arc shape optimizes the diffuse reflection effect. Within the cavity surrounded by the inner arc-shaped surface, light is repeatedly reflected, and energy is partially consumed, reducing the amount of light reflected from the first atomizing layer or mirror glass to the liquid crystal glass.

[0056] In one implementation of this application, the arc-shaped hollow microstructure includes a spherical hollow cavity microstructure or a rod-shaped hollow cavity microstructure.

[0057] like Figure 3 As shown, the spherical hollow cavity microstructure can be spherical or hollow ellipsoidal. The rod-shaped hollow cavity microstructure can be tubular, etc.

[0058] like Figure 3As shown, taking a spherical hollow cavity microstructure as an example, based on the characteristic that the reflection angle varies at each point on the curved surface due to the different normal directions, the microstructure is designed as an arc-shaped structure to achieve optimal diffuse reflection. Simultaneously, the inner and outer arc-shaped surfaces reflect light multiple times, utilizing resonance to dissipate light energy. Between the outer and inner arc-shaped surfaces is a solid cavity made of silica or polymer, where light is reflected multiple times; the inner arc-shaped surface surrounds an air cavity, where light is reflected multiple times.

[0059] like Figure 4 As shown, the spherical hollow cavity microstructure is composed of hollow silica nanoparticles. Because the spherical hollow cavity microstructure possesses a closed internal pore structure, not only can the refractive index of the first atomizing layer be altered by controlling the size of the closed internal pores, resulting in atomizing layers with lower refractive indices, but the closed internal pores also, to a certain extent, avoid the problems of unstable film optical performance and poor weather resistance caused by the easy adsorption of impurities from the environment by traditional open-pore materials. In other words, the closed internal pores give the first atomizing layer better self-cleaning capabilities.

[0060] Spherical hollow cavity microstructures can also be called hollow cavity spherical microstructures. Rod-shaped hollow cavity microstructures can also be called hollow cavity rod-shaped microstructures.

[0061] The arc-shaped hollow microstructure can also be other shapes, without any specific restrictions.

[0062] In one implementation of this application, the outer diameter of the spherical hollow cavity microstructure is 0.03 micrometers to 0.12 micrometers, or the outer diameter of the cross-section of the rod-shaped hollow cavity microstructure is 0.03 micrometers to 0.12 micrometers. The outer diameter of the spherical hollow cavity microstructure is greater than or equal to 0.03 micrometers and less than or equal to 0.12 micrometers. When the spherical hollow cavity microstructure is spherical, the outer diameter refers to the outer diameter of the sphere; when the spherical hollow cavity microstructure is ellipsoidal, the outer diameter refers to the maximum outer diameter along the minor axis of the ellipsoid, i.e., the outer diameter of the middle cross-section of the ellipsoid. The outer diameter of the cross-section of the rod-shaped hollow cavity microstructure is greater than or equal to 0.03 micrometers and less than or equal to 0.12 micrometers. When the rod-shaped hollow cavity microstructure is tubular, the outer diameter refers to the outer diameter of the tubing. The dimensions of the spherical hollow cavity microstructure and the rod-shaped hollow cavity microstructure can also be other sizes, and there are no specific limitations.

[0063] In one implementation of this application, the internal diameter of the spherical hollow cavity microstructure is 0.02 micrometers to 0.08 micrometers, or the internal diameter of the cross-section of the rod-shaped hollow cavity microstructure is 0.02 micrometers to 0.08 micrometers.

[0064] The internal diameter refers to the diameter of the cavity. The internal diameter of a spherical hollow cavity microstructure is greater than or equal to 0.02 micrometers and less than or equal to 0.08 micrometers. When the spherical hollow cavity microstructure is spherical, the internal diameter refers to the internal diameter of the sphere; when the spherical hollow cavity microstructure is ellipsoidal, the internal diameter refers to the maximum internal diameter along the minor axis of the ellipsoid, i.e., the internal diameter of the middle section of the ellipsoid. The internal diameter of the cross-section of a rod-shaped hollow cavity microstructure is greater than or equal to 0.02 micrometers and less than or equal to 0.08 micrometers. When the rod-shaped hollow cavity microstructure is tubular, the internal diameter refers to the inner diameter of the tubing. The dimensions of spherical and rod-shaped hollow cavity microstructures can also be other sizes, without specific limitations.

[0065] In one implementation of this application, the first atomizing layer comprises no more than two layers of cavity powder.

[0066] The first atomizing layer can consist of only one layer of cavity powder or two layers of cavity powder. Therefore, the thickness of the first atomizing layer is less than or equal to twice the outer diameter of the cavity powder sphere. The first atomizing layer can also have three or more layers of cavity powder, without any specific limitation.

[0067] In one implementation of this application, before the first mixture is obtained by mixing the cavity powder and the dispersion, the method further includes:

[0068] Cavity powders can be prepared using either the template method or the sol-gel method.

[0069] Creating cavity powder involves preparing microparticles with cavities, which can be done using either a template method or a sol-gel method. Template methods can include polymer template methods, metal oxide template methods, polyelectrolyte template methods, or soft template methods.

[0070] The sol-gel method can be used alone, or it can be combined with the template method. Furthermore, other methods can be used to prepare cavity powders; there are no specific limitations.

[0071] In one implementation of this application, the cavity powder material includes silicon dioxide or polymer material.

[0072] The cavity powder material can be silica or a polymer material. Examples of polymer materials include polycarbonate (PC) resin, polymethyl methacrylate (PMMA), or polystyrene (PS). It should be noted that the cavity powder material must be transparent. Furthermore, other materials can also be used for the cavity powder; there are no specific limitations. When the cavity powder is silica, it can also be referred to as a silica cavity structure.

[0073] In one implementation of this application, the process of attaching the first mixture to the first surface of the mirror glass of the mirror display device includes the following steps:

[0074] The first mixture is placed in a spraying machine, and the spraying machine is used to evenly spray the first mixture onto the first surface of the mirror glass. Then the mirror glass with the first mixture attached is fixed.

[0075] Alternatively, the first mixture is placed in a roller mill, and the roller mill is used to evenly coat the first mixture onto the first surface of the mirror glass, thereby fixing the mirror glass after the first mixture has been applied.

[0076] Spray coating includes air spraying, airless spraying, and electrostatic spraying. Coating methods include dip coating, spray coating, brush coating, spin coating, roller coating, and curtain coating. After spraying or coating, curing is required, which can be achieved through drying methods such as natural drying, airflow drying, spray drying, fluidized bed drying, rotary flash drying, infrared drying, microwave drying, or freeze drying. Alternatively, resin materials can be used, which do not require drying and cure automatically; specific methods are not limited.

[0077] Tempered glass can be used for mirrored glass. Because of its high reflectivity, mirrored glass can also be called high-reflectivity mirrored glass.

[0078] In another embodiment, a first mixture is attached to the first surface of the mirror glass of the mirror display device to obtain a first atomized layer, wherein the following method is used:

[0079] The first mixture is attached to a PET film and then fixed to form a frosted PET film. The frosted PET film is then pasted onto the first side of the mirror glass, and the frosted PET film pasted onto the mirror glass serves as the first frosting layer.

[0080] Using this method can further improve manufacturing efficiency and ensure product uniformity.

[0081] Specifically, to ensure the atomization effect, the haze of the mirror glass after atomization treatment in this embodiment is 20%-40%, the gloss is 60%-80%, the reflection clarity is 60%-80%, and the roughness is 0.03-0.12.

[0082] like Figure 5 As shown, this application also provides a mirror display device using the above-mentioned atomization processing method, which includes mirror glass, liquid crystal glass, and a backlight module. The side of the mirror glass facing the liquid crystal glass is the first surface of the mirror glass, and a first atomization layer is provided on the first surface of the mirror glass. The first atomization layer contains cavity powder.

[0083] There is a hollow layer between the mirror glass and the liquid crystal glass;

[0084] The light emitted by the backlight module passes sequentially through the liquid crystal glass, the hollow layer, and the mirror glass.

[0085] The following experimental examples are provided to verify the beneficial effects of this application compared with the prior art.

[0086] like Figure 1 As shown, existing mirror display devices include a backlight, an LCD glass, and a mirror glass. The backlight uses LED beads to emit light. The light emitted by the LED beads passes through the LCD glass to become the light for the displayed image. The mirror glass has a transmittance of 30% and a reflectance of 70%. Due to the effect of the mirror glass, 30% of the displayed image light passes through the mirror glass and enters the human eye, while 70% of the displayed image light is reflected multiple times by the mirror glass and the LCD glass, creating ghosting.

[0087] like Figure 2 As shown, a prior art mirror display device has a frosting layer on the side of the liquid crystal glass away from the backlight. The prior art frosting layer is disposed on the liquid crystal glass and uses a solid frosting particle material.

[0088] like Figure 5 As shown, the mirror display device of this application includes a backlight, a liquid crystal glass, a first atomizing layer, and a mirror glass. The backlight uses LED beads to emit light. The light emitted by the LED beads passes through the liquid crystal glass to become the light for the displayed image. The mirror glass has a transmittance of 30% and a reflectance of 70%. The cavity powder in the first atomizing layer can refract and reflect light in different directions, disrupting the light and preventing stable imaging, thus creating ghosting. Using this cavity powder, the optical path is more complex, improving the scattering performance of the atomizing layer. In specific implementation, the atomization design is placed on the back of the mirror glass to avoid interference fringes and allow for better mixing of scattered light, resulting in a better atomization effect.

[0089] Figure 7 This demonstrates a practical application of the mirror display device of this application.

[0090] Figure 8 The image shows the Newton's rings problem, which is quite noticeable in ordinary mirror display devices.

[0091] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
