Description

Technical Field

[0001] This application relates to the field of digital tube technology, and in particular to an 8-segment digital tube and a display device. Background Technology

[0002] With the continuous development of technology, the competitive pressure in all industries is constantly increasing, and they are all looking for technical solutions to reduce costs. The home appliance, medical and automotive industries are no exception. In order to pursue high cost performance, the digital display module is also unable to escape the impact of price. Some have even replaced the digital display module of the LCD (Liquid Crystal Display) that was previously very stable with traditional digital tubes to meet the demand for high cost performance. However, traditional digital tubes struggle to meet the requirements for displaying some compact figure-eight segments. While some types of LCD digital displays can show complex graphics and compact figure-eight segments simultaneously, traditional digital tubes face manufacturing limitations. For instance, displaying both compact figure-eight segments and complex graphics simultaneously is currently difficult with existing technology. The gap between segments in a compact figure-eight segment must be at least 0.3mm to maintain its aesthetic appeal. To display both complex graphics and figure-eight segments, traditional digital tubes require a combination of the digital tube and a digital tube TAPE (transparent film, a thin film material used in digital tubes to transmit light). The minimum spacing between the figure-eight segments in a digital tube TAPE ... The spacing between the 8-shaped segments is designed to be 0.9mm. This means that for compact 8-shaped segment displays, adjustments must be made based on the customer's original 8-shaped segment dimensions, which will affect the aesthetic appearance of the 8-shaped segments. For example... Figure 1 It shows a comparison of the compact 8-shaped segments before and after adjustment between existing technology's LCD digital display and traditional digital tube. Obviously, the adjusted 8-shaped segments are not very aesthetically pleasing. Utility Model Content

[0003] This application provides an 8-segment digital tube and a display device to solve the technical problem that traditional digital tubes are unable to simultaneously handle complex graphics and compact 8-segment displays, resulting in limited aesthetics.

[0004] In a first aspect, this application provides an 8-segment digital tube, comprising: a reflector plate having an 8-segment light-emitting hole and a receiving groove below it; a light-transmitting film attached above the reflector plate and being a transparent or semi-transparent film; and a light source assembly disposed within the receiving groove.

[0005] As an alternative example, the spacing between the light-emitting aperture of the above-mentioned figure-eight segment and the light source segments is 0.25 mm to 0.3 mm.

[0006] As an alternative example, the material of the aforementioned light-transmitting membrane is polycarbonate or polyethylene terephthalate.

[0007] As an alternative example, the light-emitting hole of the aforementioned figure-eight segment is brushed with ink of the same color as the aforementioned light-transmitting membrane.

[0008] As an optional example, the light source assembly includes: a printed circuit board having pin holes; a light source soldered to the top of the printed circuit board by solder paste or die bonding; and pins inserted into the bottom of the printed circuit board through the pin holes, the pins being connected to a power supply.

[0009] As an alternative example, both the aforementioned light-transmitting film and the aforementioned light source are visible light colors.

[0010] As an alternative example, the above-mentioned light source is packaged in one of the following ways: surface mount, flip-chip, or conventional mounting.

[0011] As an alternative example, the number of light-emitting holes of the aforementioned light source and the aforementioned figure-eight segment is the same and there is at least one.

[0012] As an alternative example, an adhesive, specifically epoxy resin, is used to encapsulate the space between the reflector and the light source assembly.

[0013] Secondly, this application provides a display device, including the above-mentioned 8-digit segment digital tube.

[0014] The technical solutions provided in this application have the following advantages compared with the prior art:

[0015] This application employs a reflector with an 8-segment light-emitting hole and a receiving groove below it; a light-transmitting film, which is a transparent or semi-transparent film, attached above the reflector; and a light source assembly, an 8-segment digital tube disposed within the receiving groove. Because the combination of the transparent or semi-transparent film and the reflector with the 8-segment light-emitting hole effectively guides light, ensures uniform brightness distribution, and improves display performance, this achieves a more compact, aesthetically pleasing, and high-precision digital tube display without increasing cost. This solves the technical problem of traditional digital tubes being unable to simultaneously handle complex graphics and compact 8-segment displays, thus limiting aesthetics.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0026] According to a first aspect of the embodiments of this application, an 8-digit segment digital tube is provided, optionally, as follows: Figure 2 and Figure 3 As shown, the above-mentioned 8-segment digital tube includes:

[0027] Reflector 1, with an 8-shaped light-emitting hole 11 on the reflector 1 and a receiving groove 12 below it;

[0028] A light-transmitting film 2 is attached above the reflector 1 and is a transparent or semi-transparent film throughout.

[0029] The light source assembly 3 is disposed within the receiving slot 12.

[0030] Optionally, in this embodiment, a compact figure-eight segment digital tube with optimized morphology and aesthetics is designed. The structure comprises: a reflector 1 (REF), a light-transmitting strip film 2 (TAPE), and a light source assembly 3. The reflector has figure-eight segment light-emitting holes 11 designed to guide light through specific areas for display. A receiving groove 12 is provided below for mounting the light source assembly 3. The light-transmitting strip film 2 covers the reflector 1 and is made of a transparent or semi-transparent film, such as PC (polycarbonate) or PET (polyethylene terephthalate). The use of a full-body segment design avoids the limitation of conventional TAPE to a minimum size (above 0.65mm), achieving a more compact figure-eight segment structure. Due to its transparent or semi-transparent design, the outline of the compact figure-eight segment light-emitting holes 11 on the lower reflector 1 is accurately reflected, resulting in a clear and detailed display effect. The light source component 3 is installed in the receiving groove 12 of the reflector 1. The light source is combined with the printed circuit board by soldering or die bonding and emits light through the figure-eight segment light outlet 11.

[0031] Optionally, in this embodiment, the combined design of the light-transmitting strip film and the reflector effectively guides the light, ensures uniform brightness distribution, and improves the display effect, such as... Figure 4 As shown, this allows for a more compact, aesthetically pleasing, and high-precision digital tube display without increasing costs.

[0032] As an alternative example, the segment spacing of the figure-eight segment light-emitting aperture 11 is 0.25 mm to 0.3 mm.

[0033] Optionally, in this embodiment, the spacing between the segments of the compact figure-eight light-emitting hole 11 on the reflector 1 is designed to be 0.25 mm to 0.3 mm. This design achieves a more compact and refined structural layout in the light-emitting hole area of ​​the reflector 1.

[0034] Optionally, in this embodiment, a fine pitch design (0.25 mm to 0.3 mm) improves the clarity and aesthetics of the display. The small pitch design allows for more complex and compact layouts of displayed content, suitable for demanding display scenarios. Through a reasonable pitch design, the reflector reduces light scattering and leakage, improving the display's contrast and brightness. Despite the more sophisticated design, a lower manufacturing cost can be maintained by optimizing the reflector's window design and its coordination with the light-transmitting film.

[0035] As an alternative example, the material of the light-transmitting membrane 2 is polycarbonate or polyethylene terephthalate.

[0036] Optionally, in this embodiment, the light-transmitting film 2 is made of polycarbonate (PC) or polyethylene terephthalate (PET). Polycarbonate (PC) has high transparency and excellent impact resistance, as well as good heat resistance and dimensional stability, making it suitable for applications requiring high strength and high light transmittance. Polyethylene terephthalate (PET) has excellent light transmittance and chemical resistance, good mechanical strength and flexibility, and lower cost, making it suitable for mass production. In compact figure-eight segment digital tubes, this light-transmitting film is used to cover the top of the reflector to ensure uniform light transmission and to map the outline of the bottom reflector window. Simultaneously, the choice of material ensures the film's light transmittance, durability, and impact resistance.

[0037] As an alternative example, the light-emitting hole 11 of the figure-eight segment is brushed with ink of the same color as the light-transmitting membrane 2.

[0038] Optionally, in this embodiment, by brushing ink of the same color as the surface of the light-transmitting film 2 onto the inside of the figure-eight segment light-emitting hole 11 of the reflector 1, color difference caused by material or light reflection differences can be effectively reduced, helping to maintain the color tone consistency of the display area and improve the overall aesthetics. At the same time, the ink brushing process helps to enhance the prominence of the figure-eight segment outline, thereby making the displayed content clearer. The ink that matches the color of the light-transmitting film 2 can absorb or block excess light, thereby preventing light from diffusing or reflecting in unnecessary areas.

[0039] By applying ink to the inside of the light-emitting hole of the reflector to match the color of the light-transmitting film, the display effect is optimized, the color difference problem is improved, and the contrast and clarity of the displayed content are enhanced.

[0040] As an optional example, such as Figure 2 and Figure 3 As shown, the light source assembly 3 includes:

[0041] Printed circuit board 31, with pin holes provided on printed circuit board 31;

[0042] The light source 32 is soldered onto the printed circuit board 31 by solder paste or die bonding wire bonding.

[0043] Pin 33 is inserted into the bottom of the printed circuit board 31 through a pinhole interference fit, and pin 33 is connected to the power supply.

[0044] Optionally, in this embodiment, the light source assembly 3 includes a printed circuit board 31, a light source 32, and pins 33. The printed circuit board 31 serves as the basic carrier of the light source assembly 3, supporting and connecting all parts of the entire light source assembly 3. It has pin holes for the pins 33 to be inserted and electrically connected, providing stable support and electrical connection. The light source 32 is the actual light source, fixed above the printed circuit board 31 by solder paste soldering or die bonding, responsible for providing light. The light source 32 emits light energy to the display area of ​​the figure-eight segment through an appropriate light-emitting method (e.g., LED), ensuring the display effect of the digital tube. The pins 33 are inserted into the bottom of the printed circuit board 31 through pin holes with interference fit and connected to the power supply. The pins 33 play the role of power transmission, providing the required power to the light source 32 through the connection with the power supply. After the power supply is connected through the pins 33, the power is transmitted to the light source 32, causing it to emit light, and the electrical connection is stably transmitted through the printed circuit board 31. The light emitted by the light source passes through the combination of the reflector 1 and the light-transmitting film 2, ultimately displaying the compact figure-eight segment display effect, as shown in the figure-eight segment display. Figure 4 As shown.

[0045] As an alternative example, both the light-transmitting membrane 2 and the light source 32 are visible light colors.

[0046] Optionally, in this embodiment, the main function of the light-transmitting film 2 is to uniformly transmit the light emitted by the light source to the display area while maintaining the required color effect. Selecting a light-transmitting film of a visible light color ensures that the light transmission is more natural and meets visual requirements during the digital tube display process. The color selection is optimized according to the display effect requirements to ensure visual consistency and brightness of the display area. The light source 32 uses a visible light color to provide brightness, which directly affects the color and clarity of the displayed content. Using a visible light source ensures the color saturation of the digital tube display content, guaranteeing clarity and visual effect. The light-transmitting film 2 and the light source 32 can use the same visible light color, which ensures color consistency, reduces color difference between different components, and helps improve the overall display effect.

[0047] As an alternative example, the light source 32 can be packaged in one of the following ways: surface mount, flip-chip, or conventional mounting.

[0048] Optionally, in this embodiment, the light source 32 is packaged using one of the following methods: surface mount, flip-chip, or conventional mounting. Each packaging method has its specific advantages and is suitable for different design requirements and operating environments. Surface mount technology (SMD) is a packaging method that directly mounts electronic components onto the surface of a circuit board. The light source 32 is directly soldered onto the printed circuit board using this method, which is suitable for high-density, miniaturized designs and can save circuit board space. Flip-chip packaging technology involves flipping a semiconductor chip onto a circuit board, with electrical connections made through solder balls or solder joints on the chip. Since the light source chip is in direct contact with the bottom surface of the circuit board, heat can be dissipated more effectively, making it suitable for high-power light sources. Conventional mounting involves passing the light source's leads through the circuit board and connecting them by soldering to the other side of the circuit board. Because its leads penetrate the circuit board, conventional mounting has higher mechanical strength and is suitable for rougher working environments.

[0049] As an alternative example, the number of light source 32 and the number of light-emitting holes 11 in the figure-eight segment are the same and there is at least one.

[0050] Optionally, in this embodiment, the number of light sources 32 is the same as the number of light-emitting holes 11, which can ensure that each light source corresponds to one light-emitting hole, thereby ensuring that light can pass through all the light-emitting holes evenly. This helps to optimize the distribution of light and avoid insufficient light sources or uneven light concentration.

[0051] As an optional example, such as Figure 2 and Figure 3 As shown, an adhesive 4 is used to seal between the reflector 1 and the light source assembly 3. The adhesive is epoxy resin.

[0052] Optionally, in this embodiment, the reflector 1 and the light source assembly 3 are encapsulated with adhesive 4. The encapsulating adhesive between the reflector 1 and the light source assembly 3 is epoxy resin adhesive (adhesive 4). This adhesive is used to ensure a stable bond between the reflector 1 and the light source assembly 3. Epoxy resin adhesive has good mechanical strength and stability and can resist the influence of external forces such as vibration and impact, thereby maintaining long-term stability.

[0053] As an alternative example, the fabrication process of a compact 8-segment digital tube with optimized morphology and aesthetics is as follows:

[0054] 1. Pin 33 is inserted into the printed circuit board 31 by interference fit with the pin hole on the printed circuit board 31;

[0055] 2. The light source 32 is bonded to the printed circuit board 31 by solder paste soldering or traditional die bonding wire bonding to obtain the light source assembly 3;

[0056] 3. The figure-eight light-emitting hole 11 of the reflector 1 is sealed with special tape. Epoxy resin (adhesive 4) is poured into the receiving groove 12 of the reflector 1, and the combined light source assembly 3 is inserted into the receiving groove 12. After the epoxy resin is baked and cured, the special tape on the figure-eight light-emitting hole 11 of the reflector 1 is removed.

[0057] 4. A light-transmitting film 2 is attached above the figure-eight segment light-emitting hole 11 of the reflector 1, thus obtaining the effect shown in the figure-eight segment. Figure 2 and Figure 3 The image shown is a compact 8-segment digital tube with optimized form and aesthetics.
