A beacon display device and display equipment

Abstract

This invention discloses a beacon display device and a display apparatus, relating to the field of display technology. An external light beam enters from the transparent material area of ​​the beacon layer and is incident on a first transparent refraction device. A light-absorbing component is located in the transmission direction of the light beam after refraction by the first transparent refraction device, ensuring that the external light beam is absorbed by the light-absorbing component after refraction. Therefore, when the light source is off, the human eye sees black from the transparent material area of ​​the beacon layer, matching the color of the light-absorbing material area, achieving a "one-piece black" effect and ensuring "screen-off aesthetics." Furthermore, when the light is on, because the illumination beam exits from the transparent material area of ​​the beacon layer to the human eye, there is no need to use high-energy-consuming light sources such as LEDs for illumination, allowing the human eye to see the beacon. Thus, while achieving "screen-off aesthetics," energy consumption is reduced.

Description

Technical Field

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

[0002] To achieve "screen-off aesthetics," the related all-in-one black beacon products use a black ink coating and a gray / black material with very low transmittance as a cover. When external light shines on the gray / black material, the low transmittance of the gray / black material hides the external light, thus achieving an all-in-one black effect.

[0003] However, when the illumination beam shines on low gray / black materials, in order for the human eye to see the beacon, it is necessary to use a light source such as a high-energy-consuming light-emitting diode (LED) for illumination, which leads to an increase in energy consumption while achieving "screen-off aesthetics".

[0004] Therefore, it is evident that while achieving "screen-off aesthetics," reducing energy consumption is a technical problem that urgently needs to be solved by researchers in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a beacon display device and display equipment to solve the technical problem that in related integrated black beacon products, a black ink coating and a gray / black material with very low transmittance are used as the cover plate. When the illumination beam shines on the low gray / black material, in order for the human eye to see the beacon, a light source with high energy consumption such as LED is required for illumination, which leads to increased energy consumption while achieving "screen-off aesthetics".

[0006] To solve the above-mentioned technical problems, the present invention provides a beacon display device, comprising: a light source, and further comprising: a transparent cover plate, a beacon layer, a first transparent refractive device, and a light-absorbing component; wherein, the beacon layer includes a transparent material area;

[0007] An external light beam passes sequentially through the transparent material areas of the transparent cover plate and the beacon layer and is incident on the first transparent refraction device;

[0008] The light-absorbing component is located in the transmission direction of the external light beam after it has been refracted by the first transparent refractive device;

[0009] The illumination beam emitted by the light source passes through the first transparent refraction device and exits from the transparent material area of ​​the beacon layer to the human eye.

[0010] Preferably, it further includes: a second transparent refraction device; the illumination beam emitted by the light source is refracted by the second transparent refraction device and then incident on the first transparent refraction device.

[0011] Preferably, the first transparent refractive device is a first prism;

[0012] The first surface of the first prism is in contact with the surface of the beacon layer and is parallel to the surface of the beacon layer;

[0013] The second surface of the first prism is perpendicular to the surface of the beacon layer, and the light-absorbing component covers the second surface of the first prism.

[0014] Preferably, the second transparent refractive device is a second prism; the refractive index of the first prism is greater than the refractive index of the second prism;

[0015] The first surface of the second prism is in contact with the surface of the light source and is parallel to the surface of the light source;

[0016] The second surface of the second prism is perpendicular to the surface of the beacon layer.

[0017] Preferably, the wedge angle of the first prism is the same as that of the second prism.

[0018] Preferably, the second prism is made of transparent PMMA plastic, and the wedge angles of the first prism and the second prism are in the range of 39.3° to 42.1°.

[0019] Preferably, the light-absorbing component is a light-absorbing film coated on the first prism.

[0020] Preferably, the light source is an electroluminescent cold light sheet.

[0021] Preferably, it further includes a support component; the light source is mounted on a circuit board; one end of the support component is in contact with the surface of the beacon layer, the other end is in contact with the surface of the circuit board, and the surface of the support component is in contact with the second surface of the second prism.

[0022] To address the aforementioned technical problems, the present invention also provides a display device, including the aforementioned beacon display device.

[0023] In the beacon display device provided by this invention, an external light beam enters from the transparent material area of ​​the beacon layer and is incident on the first transparent refraction device. The light-absorbing component is located in the transmission direction of the light beam after being refracted by the first transparent refraction device, so that the external light beam is absorbed by the light-absorbing component after being refracted by the first transparent refraction device. Therefore, when the light source is not turned on, the human eye sees black from the transparent material area of ​​the beacon layer, which is consistent with the color of the light-absorbing material area of ​​the beacon layer, achieving a "one-piece black" effect and ensuring "screen-off aesthetics". Secondly, compared with the previous method of illuminating low gray / black materials with illumination beams, which requires the use of high-energy-consuming light sources such as LEDs, this beacon display device, when the light is on, does not require the use of high-energy-consuming light sources such as LEDs to illuminate the human eye because the illumination beam is emitted from the transparent material area of ​​the beacon layer. Thus, the human eye can see the beacon while achieving "screen-off aesthetics".

[0024] In addition, the present invention also provides a display device, including the beacon display device mentioned above, which has the same or corresponding technical features as the beacon display device mentioned above, and has the same effect. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present invention.

[0032] The core of this invention is to provide a beacon display device and display equipment to solve the technical problem that in related integrated black beacon products, a black ink coating and a gray / black material with very low transmittance are used as the cover plate. When the illumination beam shines on the low gray / black material, in order for the human eye to see the beacon, a light source with high energy consumption such as LED is required for illumination, which leads to increased energy consumption while achieving "screen-off aesthetics".

[0033] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Figure 1 This is a schematic diagram of a beacon display device provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the beacon display device includes: a light source, and further includes: a transparent cover plate, a beacon layer, a first transparent refractive device, and a light-absorbing component; wherein, the beacon layer includes a transparent material area;

[0034] An external light beam passes sequentially through the transparent material areas of the transparent cover plate and the beacon layer and then enters the first transparent refraction device;

[0035] The light-absorbing component is located in the transmission direction of the external light beam after it has been refracted by the first transparent refraction device;

[0036] The illumination beam emitted by the light source passes through the first transparent refraction device and exits from the transparent material area of ​​the beacon layer to the human eye.

[0037] The light source used is not limited and can be various light sources such as electroluminescent (EL) cold light sheets, organic light-emitting diode (OLED) light-emitting sheets, and LED light guide sheets. The transparent cover can be a transparent plastic cover. The beacon layer includes a transparent material area and a light-absorbing material area, wherein the transparent material area is located in the middle area, and the light-absorbing material area is located around the transparent material area. The first transparent refractive device is not limited and can be, for example, a prism. The light-absorbing component is located in the transmission direction of the light beam refracted by the first transparent refractive device. In practice, the light-absorbing component can be formed by coating the light-emitting surface of the first transparent refractive device, or a light-absorbing plate can be placed behind the light-emitting surface of the first transparent refractive device as the light-absorbing component.

[0038] For aesthetic purposes, in some embodiments, the beacon display device further includes a second transparent refractive device. Figure 2 This is a schematic diagram of another beacon display device provided in an embodiment of the present invention, as shown below. Figure 2 As shown, the beacon display device includes a light source, a transparent cover plate, a beacon layer, a first transparent refractive device, a light-absorbing component, and a second transparent refractive device. The illumination beam emitted by the light source is refracted by the second transparent refractive device and then incident on the first transparent refractive device.

[0039] The second transparent refractive device is not limited and can be, for example, a prism. Compared to a beacon display device where the illumination beam emitted by the light source passes through the air and enters the first transparent refractive device, in the beacon display device provided in this embodiment, the illumination beam emitted by the light source passes through the second refractive device and then through the first transparent refractive device. The second transparent refractive device can precisely control the refraction angle and propagation direction of the light through its shape and material. The beam enters the first transparent refractive device after passing through the second transparent refractive device, which is equivalent to performing two directional deflection controls on the beam, allowing for more flexible and precise adjustment of the beam's path and direction, enabling it to propagate according to specific requirements.

[0040] In some embodiments, the first transparent refractive device is a first prism, and the second transparent refractive device is a second prism. The first surface of the first prism is in contact with and parallel to the surface of the beacon layer; the second surface of the first prism is perpendicular to the surface of the beacon layer, and a light-absorbing component covers the second surface of the first prism. The first surface of the second prism is in contact with and parallel to the surface of the light source; the second surface of the second prism is perpendicular to the surface of the beacon layer.

[0041] To ensure that the illumination beam emitted by the light source passes through the first and second prisms sequentially before exiting the transparent material area of ​​the beacon layer, the refractive index of the first prism is greater than that of the second prism in practice. There are no restrictions on the refractive indices of the first and second prisms, as long as the refractive index of the first prism is greater than that of the second prism.

[0042] In some embodiments, the wedge angle of the first prism is the same as that of the second prism. There are no limitations on the wedge angles of the first and second prisms, as long as they are the same.

[0043] By setting the wedge angles of the first and second prisms to be identical, two things are achieved: First, optical path matching and compensation are realized, ensuring that the angular changes caused by refraction are consistent as light propagates through the two prisms. This allows light to propagate in a specific, preset direction after refraction through the two prisms, achieving accurate control of the optical path and ensuring that the illumination and external optical paths transmit and interact as designed. Second, it ensures consistency in optical performance. The identical wedge angles help reduce optical problems such as aberrations and chromatic aberrations caused by differences in prism structure, making the entire optical system more stable and reliable in imaging and light transmission. Furthermore, it facilitates calibration and debugging. During system production, assembly, and debugging, identical wedge angles simplify calibration procedures. Because the two prisms act on light in similar ways, it is easier to find unified standards and methods when adjusting and optimizing the optical path, improving production efficiency and debugging accuracy.

[0044] In some embodiments, the second prism is made of transparent PMMA plastic, and the wedge angles of the first and second prisms range from 39.3° to 42.1°. Since PMMA has a light transmittance of up to 92% or even higher, it allows light to pass through with high efficiency, minimizing light loss when the light beam enters the first prism after passing through the second prism, thus ensuring the clarity and brightness of the imaging or optical path system.

[0045] In some embodiments, to ensure the stability of the beacon display device, the light-absorbing component in the beacon display device is a light-absorbing film coated on the first prism. If a light-absorbing plate is installed as the light-absorbing component behind the light-emitting surface of the first transparent refractive device, the light-absorbing plate is usually installed behind the light-emitting surface of the first transparent refractive device by mechanical fixing or other means. This connection method may loosen or shift when affected by factors such as vibration and temperature changes, causing the light-absorbing plate to fail to accurately absorb light, affecting the performance of the beacon display device and reducing its stability. In contrast, the present invention directly coats the light-absorbing film onto the first prism, forming an integral structure with the first prism, eliminating the problem of loose connection or displacement. When faced with vibration, temperature changes, etc., the light-absorbing film can work in conjunction with the first prism to maintain good light absorption performance, thereby improving the structural and operational stability of the beacon display device.

[0046] In some embodiments, the light source is an EL (Elastic Optical Cell) cold light sheet. On one hand, it has the advantages of being lightweight and portable: the thinner EL cold light sheet facilitates the overall slim design of the device, making it easy to integrate into the beacon display device without occupying too much space. On the other hand, it has the advantages of uniform light emission: it provides a more uniform illumination path, reducing differences in light intensity and making the beacon area receive light more evenly, which is beneficial for subsequent optical processes such as beam refraction and propagation. Furthermore, it has the advantages of low power consumption: compared to some traditional light sources, EL cold light sheets consume less energy, reducing the overall power consumption of the device and extending its operating time.

[0047] In some embodiments, to improve the stability of the beacon display device structure, the beacon display device further includes a support member; the light source is mounted on a circuit board. One end of the support member contacts the surface of the beacon layer, the other end contacts the surface of the circuit board, and the surface of the support member contacts the second surface of the second prism.

[0048] Figure 3 This is an overall structural diagram of a beacon display device provided in an embodiment of the present invention, as shown below. Figure 3 As shown, the system includes a PC cover plate, a beacon layer (including the black painted area of ​​the beacon layer and the beacon area of ​​the beacon layer), a first PC prism, a light-absorbing film, a second PMMA prism, an EL cold light sheet, a PCB board, and a support. The first PC prism has a black coating, i.e., the light-absorbing film. The PC cover plate, the beacon layer, and the first prism are made of transparent PC plastic, and the second prism is made of transparent PMMA plastic. The transmittance of all materials is higher than 90%, and the reflectivity of the black coating of the first prism and the black painted area of ​​the beacon layer is lower than 4%. The wedge angle α of the first prism and the second prism is the same, and must be between 39.3° and 42.1°. Figure 4 An optical path diagram of external light provided for an embodiment of the present invention. For example... Figure 4 As shown, external light is output after being refracted by the first PC prism. Figure 5 The optical path diagram of EL light provided in the embodiments of the present invention is shown below. Figure 5 As shown, the light beam emitted by the EL cold light sheet is refracted by the second PMMA prism and then output. The wedge angles of the first PC prism and the second PMMA prism are both α.

[0049] When the light source is off, external light shines on the black paint area of ​​the beacon layer and is absorbed by the black paint. The light then passes through the beacon area and continues to propagate downwards, eventually being absorbed by the black coating of the first PC prism, achieving a seamless black effect.

[0050] When the light source is turned on, the light emitted by the EL cold light sheet passes through the second PMMA prism and the first PC prism in sequence, enters the beacon area of ​​the beacon layer, and is finally perceived by the human eye, thus realizing the normal beacon display function.

[0051] In the beacon display device provided in this embodiment of the invention, an external light beam enters from the transparent material area of ​​the beacon layer and is incident on the first transparent refraction device. The light-absorbing component is located in the transmission direction of the light beam after being refracted by the first transparent refraction device, so that the external light beam is absorbed by the light-absorbing component after being refracted by the first transparent refraction device. Therefore, when the light source is not turned on, the human eye sees black from the transparent material area of ​​the beacon layer, which is consistent with the color of the light-absorbing material area of ​​the beacon layer, achieving a "one-piece black" effect and ensuring "screen-off aesthetics". Secondly, compared with the previous method of illuminating low gray / black materials with illumination beams, which requires the use of high-energy-consuming light sources such as LEDs, this beacon display device, when the light is on, does not require the use of high-energy-consuming light sources such as LEDs to illuminate the human eye because the illumination beam is emitted from the transparent material area of ​​the beacon layer. Thus, the human eye can see the beacon while achieving "screen-off aesthetics".

The display device provided in this embodiment has the same or corresponding technical features as the beacon display device described above. The embodiments of the beacon display device have been described in detail above, and the embodiments of the display device will not be repeated here.

[0053] The display device provided in this embodiment includes a beacon display device. In the beacon display device, an external light beam enters from the transparent material area of ​​the beacon layer and is incident on the first transparent refraction device. The light-absorbing component is located in the transmission direction of the light beam after being refracted by the first transparent refraction device, so that the external light beam is absorbed by the light-absorbing component after being refracted by the first transparent refraction device. Therefore, when the light source is not turned on, the human eye sees black from the transparent material area of ​​the beacon layer, which is consistent with the color of the light-absorbing material area of ​​the beacon layer, achieving a "one-piece black" effect and ensuring "screen-off aesthetics". Secondly, compared with the previous method of illuminating low gray / black materials with a light beam, which requires the use of high-energy-consuming light sources such as LEDs for illumination, this beacon display device does not require the use of high-energy-consuming light sources such as LEDs for illumination when the light is on, because the light beam is emitted from the transparent material area of ​​the beacon layer to the human eye. Thus, the human eye can see the beacon while achieving "screen-off aesthetics".
