DETAILED DESCRIPTION

[0032] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0033] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0034] In the present disclosure, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the space when the light board is in use. "Inside" and "outside" refer to the inside and outside relative to the outline of the component or structure itself. In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0035] In the related art, in order to enable users to clearly see the button position at night or when the brightness in the car is low, a button indicator light is developed as needed, such as Fig. 9As shown, the existing key indicator lights mainly use a direct light source, the principle of which is that the light emitting element 3 is directly facing the mask (e.g., the light emitting surface 120), and the light is dispersed by the light homogenizing effect of the light homogenizing element 5, lighting up the entire mask to achieve the indication effect. However, the light emitted by the light emitting element 3 is not evenly irradiated on the mask, but gradually darkens from the illuminated center to the surroundings. Therefore, when the required mask (e.g., the light emitting surface 120) is relatively large, the overall unevenness will appear, and the visual effect is poor. In addition, affected by the above problems, the mask width of the indicator light is usually small, and the overall applicability is low.

[0036] Based on this, according to the first aspect of the present disclosure, referring to Figures 1 to 8 As shown, the light guide plate includes a main body 1 and a scattering structure 2. The main body 1 has a light-incoming surface 110 and a light-emitting surface 120. The light-incoming surface 110 is located on the side of the light-emitting surface 120. The scattering structure 2 is arranged on the light-incoming surface 110 to diffuse the light emitted from the light-emitting component 3 into the main body 1.

[0037] Through the above technical solution, that is, the light guide plate provided by the present disclosure, by providing a scattering structure 2 on the light inlet surface 110 of the main body 1, the light emitted by the self-luminous element 3 can diffuse into the main body 1 after entering the main body 1, thereby increasing the width of the light emitted at the light inlet surface 110, and improving the uniformity of the light entering, which is beneficial to improving, for example, the uniformity of the display brightness of the display device and improving the visual effect. In addition, since the light inlet surface 110 is located on the side of the light outlet surface 120, that is, it can be understood that the present disclosure can avoid the problem of, for example, the light emitting element 3 and the light outlet surface 120 being directly emitted in the related art by arranging the light outlet surface 120 so as not to be opposite to the light emitted by the light emitting element 3, which makes it possible to avoid the problem of uneven display brightness and poor visual effect of the display device when the light outlet surface 120 is larger. Therefore, the light guide plate provided by the present disclosure can solve the problem of uneven display brightness and poor visual effect of the display device in the related art.

[0038] In some embodiments, reference Figures 1 to 8 As shown, the main body 1 also has a backlight surface 130 arranged opposite to the light emitting surface 120, and a grid structure 4 is provided on the backlight surface 130, so that at least part of the light in the main body 1 after being reflected by the grid structure 4 can be emitted from the light emitting surface 120, and the light emitted by the self-luminous element 3 and incident into the main body 1 through the above-mentioned light inlet surface 110 can be reflected by the grid structure 4 so that at least part of the light can be emitted from the light emitting surface 120, that is, the above-mentioned grid structure 4 can destroy the total reflection of the light inside the main body 1 of the light guide plate, so that the light can be emitted from the light emitting surface 120 of the light guide plate, thereby improving the display brightness and display clarity of, for example, a display device, and achieving a better visual effect.

[0039] Among them, since the present disclosure arranges the light emitting surface 120 not to be arranged opposite to the light emitted by the light emitting member 3, that is, does not use the direct light source, it can avoid the problem of overall unevenness and poor visual effect when the required mask (such as the light emitting surface 120) is relatively large due to the direct light source. For example, in the related art, such as Fig. 9 As shown, the light source is directly emitted, so that the width of the light emitting surface 120 of the display device, such as the indicator light, along the first direction is usually 3-5 mm. However, the present disclosure optimizes the structure of the light guide plate, such as Figure 5 As shown, the width of the light emitting surface 120 of the display device, such as the indicator light, along the second direction can be 8-10 mm, but is not limited thereto. For example, those skilled in the art can adaptively adjust the structural dimensions of the main body 1, the scattering structure 2 and the mesh structure 4 of the light guide plate, thereby enabling the light guide plate to be applied to display devices of different sizes and forms, which has higher applicability. The present disclosure will not be elaborated in detail here.

[0040] It should be noted that the first direction mentioned above can refer to Fig. 9 The second direction can refer to Figure 5 The left-right direction of the center drawing.

[0041] In addition, the light emitting principle of the above-mentioned light guide plate is based on the principle of light refraction and reflection. Specifically, light propagates in a straight line in a homogeneous medium. Light reflection refers to the phenomenon that light changes its propagation direction at the interface between two substances and returns to the original substance. The incident light, reflected light and normal line are on the same plane, the reflected light and the incident light are on both sides of the normal line, and the incident angle and the reflection angle are equal.

[0042] When light is incident on the interface of two media, part of the light will be reflected. If the second medium that the light enters is opaque, the other part of the light will be absorbed. But if the second medium that the light enters is transparent, such as when light enters water or a glass lamp from air, the other part of the light will propagate in the water or glass. When light is incident from one medium to another or propagates in the same inhomogeneous medium, the propagation direction generally changes. This phenomenon is called refraction of light. The incident light, the refracted light and the normal are on the same plane. The incident light and the refracted light are on both sides of the normal. The medium with a large refractive index is called a denser medium. A medium with a small refractive index is called an optically sparse medium. When light is incident from an optically sparse medium to an optically denser medium, the angle of refraction is smaller than the angle of incidence. When light is incident from an optically denser medium to an optically sparser medium, the angle of refraction is larger than the angle of incidence. When light is incident from an optically denser medium to the interface of an optically sparser medium, all light is reflected back to the original medium. This phenomenon is called total reflection, that is, only reflection occurs without refraction. Since the angle of refraction is larger than the angle of incidence when light is incident from a denser medium to a optically sparser medium, when the angle of incidence increases to a certain value, the angle of refraction will be greater than 90°. At this time, no refracted light will appear in the optically sparser medium. As long as the angle of incidence is greater than this value, there will be no refraction.

[0043] Based on the above, in some embodiments, the light guide plate may be, for example, a PC plate (polyester plate), the refractive index of the PC plate is 1.57, which is greater than the refractive index of the air medium outside the light guide plate, wherein the refractive index of the air medium is 1, therefore, when light is incident from the air to the light guide plate, the refraction angle is less than the incident angle, so that the light can enter the light guide plate through the light inlet surface 110 of the light guide plate. Of course, the above specific embodiments are exemplary, and in other embodiments, the light guide plate may also be, for example, a PMMA plate (acrylic plate), the refractive index of the PMMA plate is 1.49, which is greater than the refractive index of the air medium outside the light guide plate, the present disclosure is not limited thereto, and those skilled in the art may design adaptively according to actual application requirements, the purpose of which is to enable the light guide plate to be constructed as a light-dense medium relative to the medium outside the light guide plate.

[0044] In addition, the light guide plate can be prepared by an integrated injection molding process, which is easy to manufacture and has lower cost. Of course, the light guide plate can also be prepared by integrated molding, such as by 3D printing, but the present disclosure is not limited thereto.

[0045] In some embodiments, the scattering structure 2 may be a toothed structure and / or a wave structure. For example, Figure 1 and Figure 2 As shown, the scattering structure 2 may be a toothed structure, and the arrangement direction of the plurality of toothed monomers of the toothed structure may be parallel to the light emitting surface 120 or the backlight surface 130, for example, along a third direction (see Figure 2The light emitted by the self-luminous element 3 can diffuse into the main body 1 after entering the main body 1, thereby increasing the width of the light emitted from the light-inlet surface 110, improving the uniformity of the incoming light, and being beneficial to improving the uniformity of the display brightness of the display device and improving the visual effect.

[0046] Of course, the specific embodiment in which the scattering structure 2 is a toothed structure is exemplary. In other embodiments not shown in the figure, the scattering structure 2 may also be, for example, a wave structure, and the arrangement direction of the plurality of wave monomers of the wave structure may be parallel to the light emitting surface 120 or the backlight surface 130, for example, along the third direction (refer to Figure 2 The present disclosure is not limited thereto, and the purpose is to increase the width of the light emitted from the light-incoming surface 110.

[0047] It should be noted that when the scattering structure 2 is constructed as a toothed structure or a wave structure, the specific size and arrangement quantity of the multiple toothed monomers or the multiple waved monomers are not specifically limited in the present disclosure, and those skilled in the art can design them adaptively according to actual application requirements. In addition, the arrangement direction of the multiple toothed monomers or the multiple waved monomers of the toothed structure can also be perpendicular to the light emitting surface 120 or the backlight surface 130, for example, along the fourth direction (refer to Figure 3 The arrangement is in the up and down direction of the drawing, and the present disclosure does not make any specific limitation on this.

[0048] In addition, the present disclosure exemplarily describes the principle of increasing the light width by the scattering structure 2, as follows:

[0049] like Figure 7 As shown, when the incident light a hits the scattering structure 2, when there is, for example, a toothed structure, the refracted light of the incident light a when passing through the interface B is a', and when there is no toothed structure, for example, under the same incident light a, the refracted light of the incident light a when passing through the interface D is a", from which it can be seen that under the same incident light a, the propagation angle of the refracted light is larger after the incident light a passes through the scattering structure 2, and therefore, the light width can be increased by the scattering structure 2.

[0050] Considering that the propagation of light in the light guide plate is based on the principle of total reflection of light, when light enters the light guide plate and the incident angle is greater than the critical angle for achieving total reflection, the light is totally reflected inside the light guide plate and no light is emitted. Figure 6 As shown, the total reflection propagation of light can reduce the loss and make the light propagate along the fifth direction (refer to Figure 5 However, in order to extract part of the light from the light guide plate and emit it from the light emitting surface 120, based on this, in some embodiments, reference Figures 1 to 5As shown, a dot structure 4 can be provided on the backlight surface 130, and the dot structure 4 can destroy the total reflection of light inside the main body 1 of the light guide plate, so that the light can be emitted from the light output surface 120 of the light guide plate, thereby improving the display brightness and display clarity of the display device, for example, and achieving a better visual effect.

[0051] The present disclosure exemplarily describes the principle of the mesh structure 4 destroying the total reflection of light, as follows:

[0052] like Figure 8 As shown, before the light in the light guide plate encounters the mesh structure 4, it propagates from light b to light c in a total reflection manner. When light c propagates to the mesh structure 4, the total reflection is destroyed by the mesh structure 4. A tangent is drawn at the contact point between light c and the mesh structure 4. The normal of the tangent is the normal of the light c reflected at this point. According to the law of reflection, light d can be obtained. Light d continues to propagate upward. Figure 4 and Figure 5 As shown, the light d propagates upward and is emitted from the light emitting surface 120 of the light guide plate. Therefore, the total reflection of the light can be destroyed by the mesh structure 4, so that at least part of the light is emitted from the light emitting surface 120 of the light guide plate.

[0053] Optionally, in some embodiments, reference Figure 1 and Figure 2 As shown, the number of the dot structures 4 can be multiple, and the multiple dot structures 4 are arranged in an array, for example, in a matrix column arrangement, so that a larger range of light can be emitted from the light-emitting surface 120, which is beneficial to improving the display brightness and display clarity of the display device, for example, and providing a better visual effect.

[0054] In addition, in some embodiments, reference Figures 1 to 4 As shown, the mesh structure 4 can be a groove 410 recessed in the backlight surface 130 , which has a simple structure and is easy to install and prepare, thereby reducing production costs.

[0055] For example, Figures 1 to 4 As shown, the groove 410 can be a hemispherical groove. The overall structure is more regular and is conducive to more uniform divergence of light, improving the uniformity of light, which is conducive to improving the display brightness and display clarity of the display device, for example, and providing better visual effects.

[0056] Among them, the specific embodiment of the above-mentioned mesh dot structure 4 is exemplary, and those skilled in the art can adaptively design the specific structure of the mesh dot structure 4, the size and arrangement quantity of the mesh dot structure 4, and the gap size between two adjacent mesh dot structures 4 according to actual application requirements. For example, by adjusting the size of the mesh dot structure 4, for example, the larger the size of the mesh dot structure 4, the more light is reflected from the mesh dot structure 4, the more light is emitted from the light-emitting surface 120, and the display brightness is higher, or by adjusting the gap size between two adjacent mesh dot structures 4 of the mesh dot structure 4, for example, the denser the mesh dot structure 4 is arranged, that is, the smaller the gap between two adjacent mesh dot structures 4, the more light is emitted from the light-emitting surface 120, and the display brightness is higher. The present disclosure is not limited to this.

[0057] In some embodiments, reference Figures 1 to 5 As shown, the main body 1 can be a polygonal plate body 140, which has a relative upper surface 141 and a lower surface 142 and a plurality of side surfaces 143 arranged in sequence in the circumferential direction around the upper surface 141 or the lower surface 142, at least one side surface 143 is formed as a light-incoming surface 110, one of the upper surface 141 and the lower surface 142 is formed as a light-emitting surface 120, and the other is formed as a backlight surface 130. By way of example, the above-mentioned polygonal plate body 140 can be, for example, a rectangular plate, and the overall structure is simple and easy to install and manufacture. Of course, the present disclosure is not limited thereto, and those skilled in the art can adaptively design it according to actual application requirements.

[0058] Furthermore, it should be noted that the light guide plate can be adaptively provided with a light-incoming surface 110, that is, at least one of the multiple side surfaces 143 arranged in sequence in the circumferential direction around the upper surface 141 or the lower surface 142 of the polygonal plate body 140 is formed as the light-incoming surface 110, so that at least one light-emitting element 3 can be adaptively provided on the opposite side of the corresponding light-incoming surface 110 according to needs, so as to ensure that the light emitted from the light-emitting surface 120 of the light guide plate meets the use requirements. Those skilled in the art can adaptively design according to the actual application requirements, and the present disclosure does not make specific limitations here.

[0059] According to the second aspect of the present disclosure, a light-emitting assembly is provided, which includes a light-emitting element 3 and the above-mentioned light guide plate, so as to solve the problem of uneven brightness and poor visual effect of the display device in the related art. In addition, the above-mentioned light-emitting assembly also has all the beneficial effects of the above-mentioned light guide plate, which will not be repeated in this disclosure.

[0060] The light emitting element 3 may be, for example, a laser, a light emitting diode, or an LED lamp, etc. The present disclosure does not make any specific limitation thereto, and its purpose is to provide a light source.

[0061] In addition, considering that the light in the light guide plate is extracted by the mesh structure 4, most of the light is directed upward (see Figure 5 The light is transmitted in the vertical direction of the drawing, which leads to a phenomenon that the brightness of the position corresponding to the light-emitting surface 120 with the dot structure 4 is higher than that of the position without the dot structure 4. Since the distribution of the dot structure 4 is not continuous but has spacing, the light is extracted by the dot structure 4. What is seen on the light-emitting surface 120 is a small bright spot with spacing. Therefore, in order to ensure uniform light emission on the light-emitting surface 120, improve the uniformity of the display brightness of the display device and improve the visual effect, in some embodiments, reference Figure 5 As shown, the light-emitting component may further include a light homogenizer 5, which is arranged on the light output path of the light output surface 120. By way of example, the light homogenizer 5 may be, for example, a light homogenizer plate or an atomizer plate, so as to improve the uniformity of display brightness of, for example, a display device and improve the visual effect. The overall structure is simple and easy to install and manufacture.

[0062] Among them, it should be noted that the above-mentioned light homogenizing plate or atomizing plate can be, for example, a light homogenizing plate body or a light homogenizing film or an atomizing plate body or an atomizing film that is well known in the art. The present disclosure does not specifically limit such deformation methods. Those skilled in the art can design it adaptively according to actual application requirements. The purpose is to be able to set the light homogenizing plate or atomizing plate on the light output path of the light output surface 120 to improve the uniformity of the light. Since the above-mentioned light homogenizing plate or atomizing plate is usually made by adding optical scattering particles to a transparent substrate, when the light is emitted from the light guide plate and passes through the light homogenizing plate or atomizing plate, the light will pass through media with different refractive indices, and the light can undergo many refractions, reflections and scattering phenomena to achieve the effect of optical diffusion. Secondly, when the light is diffused, the light radiation area increases accordingly, and the light intensity per unit area is reduced. Therefore, when the light passes through the light homogenizing plate or atomizing plate, the irradiated area becomes larger and the uniformity is better. The above-mentioned specific principle can be achieved by a light homogenizing plate or atomizing plate that is well known in the art, and the present disclosure will not elaborate on this.

[0063] like Figure 8 As shown, considering that when the light c propagates to the mesh structure 4, the total reflection is destroyed by the mesh structure 4, a part of the light is reflected at the mesh structure 4 to obtain the light d, the light d propagates upward and is emitted from the light emitting surface 120 of the light guide plate, and the other part of the light is refracted at the mesh structure 4 to obtain the light e, and the light e is reflected at the other end of the mesh structure 4 to obtain the light f, and the light f escapes from the back of the light guide plate. Since the escaped light f is energy loss, in order to collect the escaped light f and improve the energy utilization rate, in some embodiments, reference Figure 5As shown, the light-emitting component may further include a reflector 6, which is disposed on the light-emitting path of the backlight surface 130 arranged opposite to the light-emitting surface 120, so as to reflect the escaped light f so that at least part of the light is re-incident into the light guide plate for transmission. Under the premise of the same light source energy, the energy utilization rate can be improved by adding the reflector 6, and the display brightness of the display device and the visual effect can be improved, for example.

[0064] It should be noted that the reflective element 6 can be, for example, a reflective plate or a reflective film that is well known in the art. The present disclosure does not limit the specific structure of the reflective plate or the reflective film. The purpose is to be able to set the reflective plate or the reflective film on the light output path of the backlight surface 130 to improve energy utilization, and to be able to improve, for example, the display brightness of the display device and improve the visual effect.

[0065] According to a third aspect of the present disclosure, a display device is provided, the display device comprising the above-mentioned light-emitting component, so as to solve the problem of uneven brightness and poor visual effect of the display device in the related art. In addition, the above-mentioned display device also has all the beneficial effects of the above-mentioned light-emitting component, which will not be described in detail in the present disclosure. The above-mentioned display device can be any display device capable of displaying content, such as an indicator light, a computer display screen, or a mobile phone screen, and the present disclosure does not specifically limit this.

[0066] According to a fourth aspect of the present disclosure, a vehicle is provided, comprising the above-mentioned display device. The vehicle has all the beneficial effects of the above-mentioned display device, which are not described in detail in the present disclosure. The display device of the vehicle may be, for example, a button indicator light or a paddle indicator light or an in-vehicle display screen in the vehicle, which is not specifically limited in the present disclosure.
