Description

TECHNICAL FIELD

[0002] The existing LED-based imaging screens mostly adopt rigid panel structures, which are fixed in size and shape and cannot adapt to complex wall environments such as curved surfaces and irregular contours. Moreover, professional personnel are required to perform overall debugging during installation, which makes it difficult to meet the DIY assembly needs of users. Meanwhile, the lamp strips of traditional LED screens usually adopt centralized control mode, and after being cut, the overall circuit is prone to failure, which cannot realize flexible adjustment of any length. In the scene of coordinated display of multiple lamp strips, signal transmission delay is prone to occur due to factors such as length difference of lamp strips and environmental temperature change, which leads to frame asynchronization of dynamic pictures and affects the display effect. In addition, the existing LED screens generally lack energy efficiency dynamic optimization mechanism, and long-term high-power operation not only increases energy consumption, but also causes light decay difference due to local overheating, which shortens the service life of the equipment. In addition, the display parameters of traditional LED screens are mostly fixed settings, which cannot be automatically adjusted according to the intensity of environmental light. In strong light or weak light environment, the picture is prone to overexposure or dimness, and the visibility is poor. More importantly, the content delivery of most LED screens depends on special control equipment and professional operation software. If a user wants to deliver videos and pictures, he needs to go through complex steps such as format conversion and parameter matching, and cannot directly realize control through a mobile phone app. The operation threshold is extremely high, and ordinary users cannot complete it independently, which seriously limits its application in non-professional scenes such as homes and small places.

In addition, the features described with reference to certain examples can be combined in other examples.

[0013] The embodiment provides a LED lamp strip based image and video playing screen, comprising a plurality of LED lamp strips, each of the LED lamp strips is integrated with a separate integrated circuit control module, the integrated circuit control module serves as a core control component of the lamp strip and has strong independent operation and driving capability. The LED lamp strip can independently drive the LED lamp beads on the corresponding LED lamp strip to complete accurate light display, including brightness adjustment, color switching and frame refreshing of dynamic pictures of each lamp bead and the like. Meanwhile, the integrated circuit control modules are used for efficient signal cooperative transmission between the LED lamp strips. Specifically, each control module is provided with a special signal transceiving interface, can perform data exchange and instruction synchronization with the control modules of other lamp strips in real time, so that the plurality of LED lamp strips can cooperatively act after splicing, form a logically unified display whole and jointly output complete and coherent video imaging pictures. The design breaks the dependence of traditional centralized control on the whole circuit, so that the working state of a single lamp strip does not excessively affect other lamp strips, and the stability and reliability of the whole screen are greatly improved. The LED light strip is specially configured to be able to implement arbitrary cutting along its length direction, and the cutting position is not limited by fixed nodes. Users can perform cutting operation at an arbitrary position according to the size requirement of the actual installation space. Moreover, the residual part after cutting can still maintain normal light emitting display function under the driving of the integrated circuit control module integrated therein, without additional circuit connection adjustment such as welding, jumper wire and the like. This feature greatly enhances the DIY adaptation ability of the screen. Users can easily adjust the length of the light strip according to the size and shape of the installation environment without professional electrical knowledge, significantly reducing the installation difficulty and cost, and also widening the application scenarios of the screen, so that it can adapt to various irregular installation spaces. The integrated circuit control module integrates an energy consumption monitoring unit and a self-calibration synchronization mechanism. The energy consumption monitoring unit can collect the working current and voltage parameters of the corresponding LED light strip in real time and accurately through the built-in high-precision current detection circuit and voltage sampling circuit. These parameters are transmitted to the operation core of the control module in real time, and after analysis and processing, they are compared with the preset power threshold. When the actual power of the light strip exceeds the preset threshold, the energy consumption monitoring unit will automatically send adjustment instructions to the driving circuit to reduce the driving power by changing the duty cycle of the driving signal, etc., on the premise of ensuring that the display effect is not significantly affected, to realize dynamic optimization of energy efficiency. This function effectively solves the problem of high energy consumption caused by long-term high-power operation of traditional LED screens, and conforms to the development trend of energy saving and environmental protection. The self-calibration synchronization mechanism is realized through high-frequency real-time signal interaction between the integrated circuit control modules. Each control module can send its working state information and timestamp signal to other modules. Through analysis of these interaction signals, the control module can accurately calculate and automatically detect the signal transmission delay caused by factors such as length difference of the light strip, change of environmental temperature, etc. Subsequently, according to the detected delay data, the self-calibration synchronization mechanism will start the built-in clock compensation algorithm to make subtle adjustments to the frame output time of each light strip, ensuring the frame synchronization accuracy of multiple LED light strips when displaying dynamic pictures, avoiding phenomena such as picture misalignment, trailing and the like that affect the viewing experience, and making the dynamic pictures more smooth and coherent. The integrated circuit control module is also integrated with a distributed thermal balance adjustment unit, which embeds multiple temperature sensing elements in different sections of the LED light strip and can collect real-time working temperature data of each section. After these temperature data are collected and analyzed, the temperature distribution and temperature gradient difference of the entire light strip are obtained. Based on these temperature information, the distributed thermal balance adjustment unit dynamically allocates the driving current of each LED lamp bead. For the sections with higher temperature, the driving current of the corresponding lamp beads is appropriately reduced to reduce the heat generation; for the sections with lower temperature, the normal driving current output is maintained to keep the overall temperature field of the light strip balanced. This design can effectively avoid the light decay difference of LED lamp beads caused by local overheating, prolong the service life of the light strip, and ensure the uniformity of the entire screen display. At the same time, when the temperature of a section exceeds the preset safety threshold, the distributed thermal balance adjustment unit automatically triggers the partition power reduction protection mechanism to reduce the power output of the region to reduce the heat generation. Moreover, the adjustment process is completed through an independent control link, which is completely separated from the display signal processing link and does not affect the continuity of the picture output, ensuring that the user's viewing experience is not disturbed while protecting the equipment. In this embodiment, further, the LED light strip is prepared using a flexible substrate. This flexible substrate has good elasticity and plasticity, so that the LED light strip has excellent bending adaptation characteristics. It can easily adapt to planar walls, curved walls with various curvatures, and irregular wall environments with uneven profiles, closely fit the wall surface, and form an integrated display surface. Compared with traditional rigid LED screens, this flexible design greatly improves the adaptability of the screen to different installation environments and can meet various personalized decoration and display requirements. The LED light strip can be embedded inside the wall or inside the board. During installation, multiple LED light strips are arranged in an orderly manner according to a predetermined arrangement, so that the light emitting surfaces of the multiple LED light strips jointly form a continuous video imaging area. This area can realize complete display of videos and pictures, whether dynamic video pictures or static picture content, can be clearly and completely presented. This embedded installation method not only makes the screen integrated with the installation environment, improving the aesthetics, but also protects the light strip to some extent, reducing damage to the light strip caused by external collision and friction. Anti-aging additives are added to the flexible substrate. These additives can effectively resist the aging and erosion of the substrate caused by environmental factors such as ultraviolet light, oxygen, and high temperature, delay the aging phenomena such as oxidation and cracking of the substrate, thereby significantly enhancing the environmental tolerance of the LED light strip during long-term use, prolonging the service life of the light strip, and reducing maintenance costs. In the present application, a further embodiment is also provided, which comprises a wireless communication module connected with the integrated circuit control module on each LED light strip through a dedicated communication interface, responsible for receiving various control signals sent by an external control terminal, and accurately transmitting these signals to the corresponding integrated circuit control module. The external control terminal is a mobile phone application, and users can generate various control instructions, such as brightness adjustment instructions, color switching instructions, video playing instructions, picture switching instructions, etc. by operating the mobile phone application, and transmit these instructions to the integrated circuit control module through the wireless communication module, to realize the functions of adjusting the light-emitting parameters of the LED light strip, controlling the video and picture content, etc. This design of using a mobile phone as a control terminal allows users to control the screen anytime and anywhere, greatly improving the operation convenience, without relying on dedicated control equipment. The wireless communication module supports multi-protocol adaptive switching, covering Wi-Fi, Bluetooth and ZigBee protocols. The built-in protocol detection and switching circuit can monitor the current signal strength in real time, and when the Wi-Fi signal strength is good, it preferentially uses the Wi-Fi protocol for communication to ensure that large data volume of video and picture files can be quickly transmitted; when the Wi-Fi signal is weak and the Bluetooth signal is good, it automatically switches to the Bluetooth protocol to balance the transmission speed and stability; when in a complex environment, both the Wi-Fi and Bluetooth signals are poor, it switches to the ZigBee protocol, which has the characteristics of low power consumption and long distance transmission, to ensure the stable transmission of control signals. Through this way of automatically selecting the optimal communication path according to the signal strength, the problem of unstable communication in different environments is effectively solved, ensuring the accurate and timely transmission of control instructions. In the present embodiment, further, an anti-tension reinforcing structure is provided inside the LED light strip, which continuously extends along the length direction of the LED light strip, and is combined with the flexible substrate and circuit layer of the LED light strip through a special composite process to form a solid overall structure. This structural design can significantly improve the structural stability of the LED light strip when subjected to tension, and when the light strip is subjected to tension during installation or use, the anti-tension reinforcing structure can effectively disperse the tension to prevent the circuit layer from being damaged due to tension, such as cracking, wrinkling, or the LED light beads from falling off, to ensure the normal operation of the light strip and prolong its service life. The buffer isolation layer is made of elastic insulating material and has good elasticity and deformation capacity. When the lamp strip is subjected to tensile force, the buffer isolation layer can absorb the stress generated in the stretching process through its own deformation, avoiding the stress from directly acting on the circuit layer and the tensile reinforcing structure, reducing the mutual abrasion and extrusion between the two, further protecting the circuit layer and the LED lamp beads, and improving the structural reliability of the lamp strip. In the embodiment, further, the preset arrangement mode includes parallel arrangement, staggered arrangement or arc-shaped arrangement and the like, and the user can select a suitable arrangement mode according to display requirements and installation environment. After the LED lamp strip is embedded in the wall body or the plate body, the light-emitting surface of the LED lamp strip is flush with the surface of the wall body or the plate body, and this design enables the entire video imaging area to form a flat display surface, effectively reducing display distortion caused by the protrusion or depression of the lamp strip, such as picture deformation, local brightness anomaly and the like, and ensuring the display quality of the picture. An optical coupling member is arranged between the two adjacent LED lamp strips, and the optical coupling member is made of optical material with high light transmittance. The special shape design of the optical coupling member can change the reflection path of light at the edge of the lamp strip, reducing the light reflection interference at the edge of the lamp strip. This makes the light transition at the splicing position of the two adjacent lamp strips more natural, reduces the splicing trace, improves the display consistency at the picture splicing position, and makes the display effect of the entire screen more uniform and coordinated. In the embodiment, further, a picture adaptation module is arranged in the mobile phone application program. When the user uses the mobile phone application program, the user inputs the arrangement parameters of the LED lamp strip, such as the number of lamp strips, the length of each lamp strip, the arrangement mode and the like. After the picture adaptation module receives these parameters, the picture adaptation module automatically constructs a virtual display model corresponding to the actual screen structure. Then, according to the virtual model, the picture adaptation module automatically processes the video and picture content selected and put by the user, including size adjustment and picture segmentation. The size adjustment is to adjust the size of the content to match the actual video imaging area through an image scaling algorithm, and the picture segmentation is to divide the content into corresponding parts according to the arrangement mode of the lamp strip and distribute the content to the corresponding lamp strip for display. Through these processes, the adjusted content can be perfectly adapted to the video imaging area formed by the plurality of LED lamp strips, ensuring complete display of the picture and avoiding missing or exceeding the display area. The picture adaptation module also has a color calibration function and can collect the illumination data of the surrounding environment, such as illumination intensity and color temperature, by calling the built-in ambient light sensor of the mobile phone. According to the collected data, the picture adaptation module automatically adjusts the display color temperature of the screen, so that the display effect of the screen can adapt to different illumination conditions. For example, in a strong light environment, the color temperature is appropriately increased to make the picture clearer, and in a weak light environment, the color temperature is reduced to avoid the picture being too dazzling, thereby ensuring that the user can obtain good viewing experience in various environments. In this embodiment, further, the integrated circuit control module has an integrated storage unit and a driving unit, wherein the storage unit has a certain storage capacity and can temporarily store video frame data or picture data to be displayed. During video or picture playback, the storage unit can cache a part of data in advance, reduce the pressure of real-time data transmission, avoid the screen freezing phenomenon caused by the delay of data transmission, and ensure the smoothness of the playback. The driving unit is a component for directly controlling the light-emitting of the LED lamp beads, and can accurately control the LED lamp beads at the corresponding positions on the LED lamp strip to emit light according to the frame data or picture data stored in the storage unit, so as to realize the clear display of dynamic video or static picture. The driving unit adopts a constant current driving mode, which can provide stable working current for the LED lamp beads, and avoid the problem of unstable brightness and color of the lamp beads caused by current fluctuation. At the same time, the driving unit supports pulse width modulation dimming, and the dimming range covers 0.1% to 100%. Users can accurately adjust the brightness of the screen according to different use scenarios and requirements, and meet various requirements from low brightness display in dim environment to high brightness display in strong light environment. In this embodiment, further, the tensile reinforcing structure is made of high-strength fiber material or metal wire material, wherein the high-strength fiber material includes aramid fiber or carbon fiber, which has extremely high strength and toughness, light weight and good corrosion resistance; the metal wire material includes stainless steel wire, which has good strength and rigidity, and relatively low cost. The distribution density of the tensile reinforcing structure in the LED lamp strip is uniformly arranged along the length direction of the lamp strip, so as to ensure the consistent tensile capacity of the lamp strip at each position in the length direction, and avoid the situation that the local tensile capacity is weak. The end of the tensile reinforcing structure is fixedly connected with the connection terminal of the LED lamp strip, forming a mechanical stress dispersion node. When the lamp strip is subjected to tension, the node can uniformly disperse the tension to the tensile reinforcing structure and the connection terminal, prevent the connection terminal from falling off or being damaged due to excessive local stress, and ensure the reliability of the connection between the lamp strip and the external circuit. In this embodiment, further, the wall or the plate body is provided with a mounting groove matched with the LED lamp strip, the size of the mounting groove is accurately matched with the cross-sectional size of the LED lamp strip, which can ensure that the lamp strip is smoothly embedded and stably installed. The inner wall of the mounting groove is provided with an insulation layer made of high-performance insulating material, which has good insulation performance. When the LED lamp strip is embedded in the mounting groove, reliable electrical isolation is achieved between the lamp strip and the wall or the plate body through the insulation layer, preventing the occurrence of electric leakage between the lamp strip and the wall or the plate body, and ensuring the safety of use. At the same time, a transparent protective cover is arranged at the opening of the mounting groove, which can completely cover the light-emitting surface of the LED lamp strip, playing a protective role of dustproof, moisture-proof and anti-collision, avoiding the entry of external sundries into the lamp strip surface to affect the display effect, or causing damage to the lamp beads due to collision. The transparent protective cover is made of high-transmittance anti-glare material, and a micro-structure optical film is arranged on the surface of the transparent protective cover. This micro-structure optical film can change the propagation direction of light and increase the scattering angle of light, thereby effectively increasing the visual angle of the picture, so that the user can clearly see the content on the screen at different viewing positions, improving the convenience and comfort of viewing. In this embodiment, further, the mobile phone application program further comprises a scene mode selection module, and the scene mode selection module is built-in with a plurality of preset display scenes, such as a cinema mode, a holiday mode, a daily lighting mode, a conference mode and the like. Each preset display scene corresponds to a specific set of light-emitting parameter combinations, such as brightness, color temperature, color saturation and the like, and a content play list matched therewith, such as a movie clip, a dark-toned background picture and the like in the cinema mode. The user can quickly make the LED lamp strip display according to the requirements of the corresponding scene by simply selecting the preset display scene on the mobile phone application program, without manually setting each parameter one by one, greatly simplifying the operation process and reducing the operation difficulty, so that even a user unfamiliar with the device can easily use it. The mobile phone application program further integrates a fault diagnosis module, which can receive various abnormal signals fed back by the integrated circuit control module in real time, such as a communication interruption signal, an over-temperature alarm signal, an over-current protection signal and the like. After receiving the abnormal signal, the fault diagnosis module will judge and locate the abnormal reason according to the built-in fault analysis algorithm, and generate corresponding fault troubleshooting guide information, such as “check the connection of the wireless communication module” and “check the heat dissipation of the lamp strip”, and the user can quickly troubleshoot and solve the fault according to the guide information, reduce the time when the device cannot work normally, and improve the maintenance efficiency of the device.
