Technical Field

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

[0002] In order to achieve the "screen-off aesthetics", the relevant integrated black beacon products use black ink coating and gray material / black material with very low transmittance as the cover plate. When external light shines on the gray material / black material, due to the low transmittance of the gray material / black material, the external light is hidden, achieving an integrated black effect.

[0003] However, when the lighting beam illuminates low-gray material / black material, in order for the human eye to see the beacon, it is necessary to use light sources such as light emitting diodes (LEDs) with high energy consumption for lighting, which increases energy consumption while achieving the "screen-off aesthetics".

[0004] It can be seen that how to reduce energy consumption while achieving the "screen-off aesthetics" is a technical problem that people in this field urgently need to solve. Summary of the invention

When the lighting beam irradiates the low gray material / black material, in order to make the human eye see the beacon, it is necessary to use high-energy-consuming LED and other light sources for lighting, which leads to increased energy consumption while achieving the "screen-off aesthetics".

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The core of the present invention is to provide a beacon display device and a display equipment to solve the technical problem that the related integrated black beacon products use black ink coating and gray material / black material with very low transmittance as the cover plate. When the lighting beam irradiates the low gray material / black material, in order to make the human eye see the beacon, it is necessary to use high-energy-consuming LED and other light sources for lighting, which leads to increased energy consumption while achieving the "screen-off aesthetics".

[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Figure 1 A schematic diagram of a beacon display device provided by an embodiment of the present invention, such as Figure 1 As shown, the beacon display device includes: a light source, and also includes: a transparent cover plate, a beacon layer, a first transparent refraction device, and a light absorbing component; wherein the beacon layer includes a transparent material area;

[0034] The external light beam passes through the transparent material area of ​​the transparent cover plate and the beacon layer in sequence and is incident on the first transparent refraction device;

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

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

[0037] There is no limitation on the light source used, which may be a variety of light sources such as electroluminescent (EL) cold light sheet, organic light emitting diode (OLED) light emitting diode, LED light guide sheet, etc. The transparent cover plate may be a transparent plastic cover plate. 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. There is no limitation on the first transparent refractive device, which may be a prism. The light absorbing component is located in the transmission direction of the light beam refracted by the first transparent refractive device. In implementation, a coating may be performed on the light emitting surface of the first transparent refractive device to form a light absorbing component, or a light absorbing plate may be provided behind the light emitting surface of the first transparent refractive device as the light absorbing component.

[0038] For the sake of aesthetics of the beacon display device, in some embodiments, the beacon display device further includes: a second transparent refraction device. Figure 2 A schematic diagram of another beacon display device provided by an embodiment of the present invention, such as Figure 2 As shown, the beacon display device includes a second transparent refraction device in addition to a light source, a transparent cover plate, a beacon layer, a first transparent refraction device, and a light absorbing component. The illumination light beam emitted by the light source is refracted by the second transparent refraction device and then incident on the first transparent refraction device.

[0039] There is no limitation on the second transparent refraction device, which may be a prism, for example. Compared with the beacon display device in which the illumination light beam emitted by the light source passes through the air and enters the first transparent refraction device, the illumination light beam emitted by the light source in the beacon display device provided in this embodiment passes through the second refraction device and then passes through the first transparent refraction device. The second transparent refraction device can accurately control the refraction angle and propagation direction of the light beam through its shape and material. The light beam passes through the second transparent refraction device and enters the first transparent refraction device, which is equivalent to two directional deflection controls on the light beam, and can more flexibly and accurately adjust the path and direction of the light beam so that it propagates 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 contacts the surface of the beacon layer and is 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 the light absorbing component covers the second surface of the first prism. The first surface of the second prism contacts the surface of the light source and is 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] In order to ensure that the illumination beam emitted by the light source can pass through the second prism and the first prism in sequence and then be emitted from the transparent material area of ​​the beacon layer, in implementation, the refractive index of the first prism is greater than the refractive index of the second prism. There is no limitation on the refractive index of the first prism and the refractive index of the second prism, as long as the refractive index of the first prism is greater than the refractive index of the second prism.

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

[0043] By setting the wedge angle of the first prism to be the same as the wedge angle of the second prism, on the one hand, optical path matching and compensation can be achieved to ensure that the angle change caused by refraction when the light propagates in the two prisms is consistent. In this way, after the light is refracted by the two prisms, it can propagate in a specific preset direction, realize accurate control of the light path, and ensure that the illumination light path and the external light path are transmitted and interacted according to the design requirements; on the other hand, the consistency of optical performance is guaranteed. The same wedge angle helps to reduce optical problems such as aberration and chromatic aberration caused by differences in prism structure, making the entire optical system more stable and reliable in imaging, light transmission, etc.; in addition, it is easy to calibrate and debug. During the production, assembly and debugging of the system, the same wedge angle can simplify the calibration steps. Since the two prisms have similar laws of action on light, it is easier to find unified standards and methods when adjusting and optimizing the light path, thereby improving production efficiency and debugging accuracy.

[0044] In some embodiments, the second prism is made of transparent PMMA plastic material, and the wedge angle of the first prism and the wedge angle of the second prism are in the range of 39.3° to 42.1°. Since the light transmittance of PMMA can reach 92% or even higher, it allows light to pass through with high efficiency, so that when the light beam passes through the second prism and enters the first prism, the light loss can be minimized to the greatest extent, thereby ensuring the clarity and brightness of the imaging or optical path system.

[0045] In some embodiments, in order 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 set behind the light-emitting surface of the first transparent refractive device as the structure of the light-absorbing component, the light-absorbing plate is usually installed behind the light-emitting surface of the first transparent refractive device by mechanical fixing or the like. When this connection method is affected by factors such as vibration and temperature changes, looseness and displacement may occur, resulting in the light-absorbing plate being unable to accurately absorb light, affecting the performance of the beacon display device and reducing its stability. However, the present invention directly coats the light-absorbing film on the first prism. The light-absorbing film is directly coated on the first prism to form an integral structure with the first prism, and there is no problem of loose connection or displacement. When facing vibration, temperature changes and the like, the light-absorbing film can work in coordination with the first prism to maintain good light-absorbing performance, thereby improving the structural stability and working stability of the beacon display device.

[0046] In some embodiments, the light source is an EL cold light sheet. On the one hand, it has the advantages of being light and portable: the EL cold light sheet is thin, which is conducive to the overall thin and light design of the device, and is convenient to be integrated into the beacon display device without taking up too much space; on the other hand, it has the advantage of uniform light emission: it can provide a relatively uniform lighting light path, reduce the difference in light brightness, make the beacon area receive light more evenly, and facilitate the subsequent refraction, propagation and other optical processes of the light beam; in addition, it has the advantage of low power consumption: compared with some traditional light sources, the EL cold light sheet has low energy consumption, which can reduce the overall power consumption of the device and extend the use time.

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

[0048] Figure 3 The overall structure diagram of a beacon display device provided by an embodiment of the present invention is as follows: Figure 3 As shown, it includes a PC cover, a beacon layer (including the black paint 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 pillar. The first PC prism has a black coating, i.e., a light-absorbing film. The PC cover, the beacon layer and the first prism are made of transparent PC plastic material, and the second prism is made of transparent PMMA plastic material. The material transmittance is higher than 90%, and the reflectivity of the black coating of the first prism and the black paint area of ​​the beacon layer is lower than 4%. The wedge angle α of the first prism and the second prism is the same, which must be an angle between 39.3° and 42.1°. Figure 4 This is a light path diagram of external light provided by an embodiment of the present invention. Figure 4 As shown, the external light is output after being refracted by the first PC prism. Figure 5 FIG. 1 is a light path diagram of EL light provided by an embodiment of the present invention. 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 angle of the first PC prism and the wedge angle of the second PMMA prism are both α.

[0049] When the light source is turned off, external light shines on the black painted area of ​​the beacon layer and is absorbed by the black paint. The middle part continues to propagate downward through the beacon area and is finally absorbed by the black coating of the first PC prism, achieving an integrated black effect.

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

[0051] In the beacon display device provided by the embodiment of the present invention, an external light beam is incident on the first transparent refraction device from the transparent material area of ​​the beacon layer; the light absorbing component is located in the transmission direction of the light beam 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 an "integrated black" effect and ensuring the "screen-off aesthetics"; secondly, compared with the previous lighting light beam irradiating low-gray materials / black materials, which requires the use of energy-intensive light sources such as LEDs for lighting, when the beacon display device is turned on, since the lighting light beam is emitted from the transparent material area of ​​the beacon layer to the human eye, there is no need to use energy-intensive light sources such as LEDs for lighting, and the human eye can see the beacon, thereby reducing energy consumption while achieving the "screen-off aesthetics".

[0052] A beacon display device is described above, and this embodiment further provides a display device, including the above-mentioned beacon display device. The display device provided in this embodiment has the same or corresponding technical features as the beacon display device described above. The embodiment of the beacon display device has been described in detail above, and the embodiment of the display device will not be repeated here.

[0053] The display device provided in this embodiment includes a beacon display device, in which an external light beam is incident from a transparent material area of ​​the beacon layer to a first transparent refraction device; the light absorbing component is located in the transmission direction of the light beam 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, what the human eye sees from the transparent material area of ​​the beacon layer is black, which is consistent with the color of the light absorbing material area of ​​the beacon layer, achieving an "integrated black" effect and ensuring the "screen-off aesthetics"; secondly, compared with the previous lighting light beam irradiating low-gray materials / black materials, which requires the use of energy-intensive light sources such as LEDs for lighting, when the beacon display device is turned on, since the lighting light beam is emitted from the transparent material area of ​​the beacon layer to the human eye, there is no need to use energy-intensive light sources such as LEDs for lighting, and the human eye can see the beacon, thereby reducing energy consumption while achieving the "screen-off aesthetics".
