Description

Technical Field

[0001] The utility model relates to the field of displays, in particular to a solar display screen and an information display screen. Background Art

[0002] An information display screen is a device for displaying various information, which is widely used in public places, such as traffic guidance, public information release, exhibition display, outdoor advertising, etc. It mainly displays information visually to the audience in the forms of text, images, videos, etc. Through the information display screen, rapid dissemination and wide coverage of information can be achieved, improving the information transmission effect and the audience participation.

[0003] Limited by the capacity of the built-in energy storage unit in the information display screen, its operating time is restricted. It often leads to the need to charge the information display screen after using electricity for a period of time. The information display screen usually needs to directly use the mains power to charge the energy storage unit in the information display screen, or through wireless charging technology for charging, the mains power charges the wireless charging device, and the radio device converts it into wirelessly chargeable electrical energy to charge the energy storage unit in the information display screen. Whether the mains power charges the information display screen indirectly or directly restricts the flexibility of its layout. Because the problem of power supply needs to be considered, either wires are laid at the location of the information display screen for charging, increasing the complexity and cost of wiring, and at the same time, the wires will also have a certain impact on the aesthetics of the display screen, and concealment treatment or other measures may be required; or the display screen is laid at the original charging interface, and there may be a problem that if multiple information display screens share a charging interface, there will be insufficient power, and the original charging interface may not meet the power demand of the information display screen, affecting the normal use of the display screen and requiring transformation or upgrade. The charging limitation of the information display screen may prevent the display screen from being laid in some special locations or places that need to be frequently moved, affecting the coverage range and effect of information display.

[0004] Refer to the display screen with a solar module whose authorization announcement number is CN217133495U. It discloses a bottom plate and a display module, and the display module is disposed on the bottom plate. Among them, the display module further includes: a liquid crystal panel, which can be transparent or semi-transparent; an assembled circuit board for electrically connecting the liquid crystal panel; and a solar module disposed between the liquid crystal panel and the assembled circuit board. The solar module is electrically connected to the liquid crystal panel and the assembled circuit board respectively. Although this technical solution solves the problem of the flexibility of its layout being restricted by charging, since its liquid crystal panel is transparent or semi-transparent, when the solar module is disposed between it and the assembled circuit board, sunlight needs to pass through the liquid crystal panel to irradiate onto the solar module, which will cause attenuation of light. This will reduce the brightness and energy of sunlight entering the solar module, thereby affecting the charging efficiency. Moreover, on the transparent or semi-transparent liquid crystal panel, the components and circuits of the solar module may cause certain obstruction or interference, affecting the clarity and color restoration degree of the liquid crystal panel display. In addition, the solar module needs to be disposed between the liquid crystal panel and the assembled circuit board, which may increase the thickness of the overall device, restricting the compactness and portability of the device.

[0048] SeeFigures 1 - 6 As shown in the figure, the present utility model provides a solar display screen, which includes a bottom plate 40 and a display module. The display module includes a panel 10, a display board 201 and a circuit board 30; the panel 10 has a display area 101, and at least part of the position of the non-display area 102 is a solar cell area 1021. By arranging the panel 10 on the surface, the solar cell area 1021 of the panel 10 can receive and utilize the energy of sunlight to the maximum extent, improving the conversion efficiency of the solar cell, so as to provide a more stable and reliable power supply for the circuit board 30; at the same time, the display area 101 does not affect the display of the display board 201, maintaining the clarity and color restoration degree of the display of the display board 201.

[0049] See Figures 1 - 3 As shown in the figure, in order to further illustrate the present utility model, a specific implementation manner is provided below. A solar display screen includes a bottom plate 40 and a display module, and the display module is arranged on the bottom plate 40; the display module includes a panel 10, a display board 201 and a circuit board 30 which are stacked in sequence from top to bottom; the panel 10 includes a display area 101 and a non-display area 102, the display area 101 is arranged corresponding to the display board 201, and at least part of the non-display area 102 is a solar cell area 1021; the circuit board 30 drives the display board 201, and the solar cell area 1021 of the panel 10 supplies power to the circuit board 30 and the display board 201.

[0050] The above display panel 201 is a display screen that visually presents information in the form of displayed text, images, videos, etc. The above circuit board 30 may include a signal input circuit, a driving signal transmission circuit, a driving unit, etc. The signal input circuit receives an input signal and performs corresponding processing. The driving signal transmission circuit transmits the processed signal to the driving unit. The driving unit identifies the signal and transmits the signal to the display panel 201 to achieve the display in the form of text, images, videos, etc. The above display area 101 is provided corresponding to the display panel 201 and is used to display the content on the display panel 201 (such as text, images, videos, etc.). The display area 101 can be formed of a light-transmitting material with a size corresponding to that of the display panel 201, or can be formed by opening a window with a size corresponding to that of the display panel 201, without affecting the display of the display panel 201 and maintaining the clarity and color restoration of the display on the display panel 201. Especially when the display area 101 is a window, it is preferable that the upper end surface of the display panel 201 is flush with the end surface of the panel 10, so that the panel 10 and the display panel 201 are closely combined together, reducing the stacked thickness (the thickness of the panel 10), avoiding additional space occupation and volume increase, and making the entire display module more compact. At least a part of the above non-display area 102 is the solar cell area 1021, that is, the non-display area 102 can be entirely the solar cell area 1021, or part of it can be the solar cell area 1021. The size of the solar cell area 1021 is related to the amount of solar energy absorbed by the solar cell area 1021 and converted into electric energy, that is, the larger the solar cell area 1021, the more electric energy is collected. The above solar cell area 1021 is used to convert solar energy into electric energy to supply power to the circuit board 30 and the display screen.

[0051] See Figure 1 and Figure 2As shown, in order to enable users to clearly understand the current state of the device through the indicator light 70 at a glance, which is convenient for operation and judgment, the indicator light 70 can also be set. The indicator light 70 is arranged between the panel 10 and the circuit board 30, located on one side of the display board 201. A light-transmitting area 1022 corresponding to the indicator light 70 is provided in the non-display area 102. The indicator light 70 is electrically connected to the circuit board 30. The above-mentioned indicator light 70 is electrically connected to the circuit board 30, and the status of the device, such as the power switch, working status, standby status, etc., can be intuitively displayed through the on / off or flashing of the indicator light 70; arranging the indicator light 70 between the panel 10 and the circuit board 30 does not affect the size of the entire solar display screen; at the same time, by setting the light-transmitting area 1022 in the non-display area 102, the indicator light 70 can be integrated with the panel 10 in the off state, without affecting the overall aesthetics of the display area 101. In the on state, whether in a dim environment or when observing the device from a long distance, users can clearly see the status of the indicator light 70, improving the visibility of the indicator light 70. The indicator light 70 can be a light-emitting diode indicator light 70, a small light bulb indicator light 70, an LED (Light Emitting Diode) lamp, etc. Preferably, an LED lamp is used. The LED indicator light 70 has the advantages of low power consumption, long life, fast response, and rich color selection. The LED indicator light 70 can also emit different colors of light, such as red, green, blue, etc., to indicate different states or functions.

[0052] See Figure 6 As shown, the above-mentioned circuit board 30 further includes an energy storage unit 304 and a charging circuit 303. The energy storage unit 304 supplies power to the circuit board 30, and the solar cell area 1021 charges the energy storage unit 304 through the charging circuit 303. The energy storage unit 304 can store the electric energy converted by the solar cell area 1021, providing stable voltage and current for the circuit board 30 and the display board 201, and can achieve independent power supply without relying on the solar cell area 1021 all the time. The energy storage unit 304 can be various types of batteries or energy storage devices for storing the electric energy converted by the solar cell area 1021. It can be a lithium-ion battery, a lead-acid battery, a nickel-cadmium battery, a super capacitor, etc. Preferably, the energy storage unit 304 is a super capacitor. The super capacitor (also known as a super battery or an electrochemical capacitor) has the advantages of high power density, fast charge and discharge speed, and long cycle life, and can be applied in situations where instantaneous high power output and frequent charge and discharge are required.

[0053] See Figure 2 and Figure 3As shown, the solar cell area 1021 of the above-mentioned panel 10 supplies power to the circuit board 30 and the display board 201, that is, the solar cell area 1021 forms an electrical connection with the circuit board 30. There are many ways to form an electrical connection, such as pin connection, welding connection, abutting, etc. In some embodiments, pin interfaces are respectively designed on the display module and the bottom plate 40, and the two are connected by pins. The pins can be made of metal materials and have a certain elasticity, and can be inserted and pulled out; the pin connection method is simple and convenient, and is suitable for situations that require frequent disassembly and replacement. In some embodiments, a conductive area 301 is provided in the solar cell area 1021, and the circuit board 30 is provided with a pole piece 302 corresponding to the conductive area 301, and the pole piece 302 and the conductive area 301 are connected together by welding to form a reliable electrical connection; the welding connection method is stable and reliable, and is suitable for situations that require long-term fixed connection; In some embodiments, a conductive area 301 is provided in the solar cell area 1021, the circuit board 30 is provided with a pole piece 302 corresponding to the conductive area 301, and the conductive area 301 and the pole piece 302 are abutted to form an electrical connection. By forming an electrical connection between the conductive area 301 and the pole piece 302, the electric energy generated in the solar cell area 1021 can be effectively transmitted into the circuit board 30. Compared with other connection methods, the abutting of the conductive area 301 and the pole piece 302 can achieve electrical connection more quickly and conveniently, and reduces the use of other connection devices. That is, one end of the pole piece 302 is fixed on the surface of the circuit board 30 facing the solar cell area 1021, and the other end abuts against the conductive area 301 when the panel 10, the display board 201 and the circuit board 30 are stacked. The part where the other end of the above-mentioned pole piece 302 abuts against the conductive area 301 can be an elastic bending protrusion, which can realize the conductive connection between electronic devices. When stacked, the pole piece 302 will generate a certain pressure and be in close contact with the conductive area 301 to form an electrical connection. By abutting the conductive area 301 and the pole piece 302, the design and assembly of the circuit board 30 can be simplified, and the electrical connection formed by the abutting of the conductive area 301 and the pole piece 302 usually has a lower contact resistance and higher stability, improves the reliability of the circuit board 30, reduces the energy loss and resistance loss during the power transmission process, ensures the stable transmission of electric energy, and prolongs the service time of the energy storage unit 304.

[0054] The above-mentioned display board 201 can be a liquid crystal display screen, an OLED display screen, an ink screen or other types of display screens. Preferably it is an ink screen. The ink screen adopts a reflective display technology and does not require backlighting. Therefore, when reading outdoors, there is no need to worry about the problem of reflection. It has a good viewing angle and a natural reading experience, will not cause eye fatigue, and is suitable for long-term reading; in addition, the ink screen only consumes energy when the page is updated. Once the display page remains unchanged, it does not require continuous energy supply to maintain the display content, can achieve lower energy consumption, prolong the battery life, and improve the service life of the device.

[0055] See Figures 1 - 3 As shown. Of course, on the basis of the above improvements, an external power supply 50 can also be added. The external power supply 50 is connected to the side of the bottom plate 40 facing away from the display module, and the external power supply 50 supplies power to the circuit board 30. The above external power supply 50 can be a battery or a battery pack composed of multiple batteries, such as a lithium battery, a nickel-metal hydride battery, etc., and can provide a mobile and wireless power supply for the circuit board 30. By supplying power to the circuit board 30 through the external power supply 50, the dependence on the solar cell area 1021 can be reduced, and the risk of unstable or interrupted circuit operation caused by the depletion of electric energy in the storage unit can be lowered, providing a stable power supply for the circuit board 30 and the display board 201, and reducing the impact of power fluctuations on the circuit board 30 and the display board 201. The external power supply 50 is connected to the side of the bottom plate 40 facing away from the display module, and various connection methods can be adopted, such as welding, plugging, clamping or other connection methods, specifically depending on the designs of the bottom plate 40 and the battery pack.

[0056] See Figure 4 and Figure 5 As shown. In order to protect the display module, a cover plate 60 can also be added. The cover plate 60 is arranged on the display module. The presence of the cover plate 60 can provide an additional protective layer to prevent the display module from being physically damaged by the outside world, such as scratches, collisions, etc. This can extend the service life of the display module and reduce the maintenance and replacement costs. It can also form a cavity for accommodating the display module between the cover plate 60 and the bottom plate 40, isolating the display module from the external environment and reducing the intrusion of dust, dirt, liquid and other pollutants into the display module. This can maintain the cleanliness and reliability of the display module. The cover plate 60 can be customized according to requirements, and different materials, colors and textures can be selected to meet the aesthetic needs of users.

[0057] The present utility model also provides an information display screen, which applies the above-mentioned solar display screen. The information display screen applying the above-mentioned solar display can automatically convert solar energy into electrical energy for the information display screen, providing a more stable and reliable power supply for the information display screen; and at the same time maintaining the clarity and color restoration degree of the information display screen.
