Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to a method and apparatus for synergistic control of light transmittance and heat dissipation of a front-emitting LED transparent screen. Background Technology

[0002] Transparent LED displays, with their transparent visual characteristics, have shown great application potential in commercial shop windows, building curtain walls, and other fields. However, in pursuit of high brightness and excellent display effects, LEDs need to be driven to emit light at high intensity, which inevitably leads to a sharp increase in heat generation from the chips. Excessive temperature not only causes light decay and color shift in LEDs, shortening device lifespan, but also threatens display stability. Existing technologies often adopt compromise solutions: either limiting brightness to control temperature rise, thus sacrificing light transmittance and visual effects; or strengthening the physical heat dissipation structure, but this blocks light and sacrifices the "transparent" quality of the screen. In addition, traditional overall uniform control strategies cannot cope with the problem of local hot spots caused by dynamic changes in the displayed content, resulting in low heat dissipation efficiency. Summary of the Invention

[0003] The main objective of this invention is to provide a method and apparatus for coordinated control of light transmittance and heat dissipation of a front-emitting LED transparent screen, so as to achieve the goal of resolving the inherent contradiction between high brightness display and efficient heat dissipation by controlling the heat dissipation of the screen while maintaining the high light transmittance display of the LED transparent screen.

[0004] To achieve the above objectives, the present invention provides a method for synergistic control of light transmittance and heat dissipation in a front-emitting LED transparent screen, comprising the following steps: Obtain the real-time transmittance and real-time temperature of the LED transparent screen; A coordinated control signal is generated based on the transmittance deviation between the real-time transmittance and the target transmittance, and the temperature deviation between the real-time temperature and the target temperature. Based on the coordinated control signal, drive and control the independently addressable LED unit groups in the LED transparent screen, and configure the light-transmitting area and heat dissipation channel in the display area of ​​the LED transparent screen.

[0005] Furthermore, the steps for obtaining the real-time transmittance and real-time temperature of the LED transparent screen include: Local illumination data is collected by photosensitive sensors deployed in the area of ​​each independently addressable LED unit group; Local temperature data is collected by temperature sensors located at the substrate positions corresponding to each independently addressable LED unit group; A weighted average calculation is performed on all the local illumination data and local temperature data to generate real-time transmittance and real-time temperature representing the overall state of the LED transparent screen.

[0006] Further, the step of generating a coordinated control signal based on the transmittance deviation between the real-time transmittance and the target transmittance, and the temperature deviation between the real-time temperature and the target temperature, includes: The transmittance deviation and temperature deviation are used as input parameters and fed into a pre-trained multi-objective decision model. The multi-objective decision model outputs a comprehensive control command. The integrated control commands are converted into coordinated control signals that can be executed by the drive system.

[0007] Furthermore, the training steps of the pre-trained multi-objective decision model include: Acquire historical light transmittance data and historical temperature data of the LED transparent screen under various operating conditions; Establish a reward function that aims to minimize transmittance fluctuations and temperature fluctuations; By using reinforcement learning algorithms, the model is trained to learn and generate comprehensive control commands based on historical data and reward functions.

[0008] Further, the steps of driving and controlling the independently addressable LED unit groups in the LED transparent screen according to the cooperative control signal, and configuring the light-transmitting area and heat dissipation channel within the display area of ​​the LED transparent screen, include: Based on the collaborative control signal, the display area is dynamically divided into multiple functional blocks; Adjust the driving current of at least one LED unit group in the first functional block to maintain the display brightness of the first functional block; Adjust the driving current and switching frequency of the LED unit group in at least one second functional block so that the LED unit group in the second functional block alternates between the lit state and the off state.

[0009] Furthermore, the step of dynamically dividing the display area into multiple functional blocks also includes: Based on real-time temperature changes, the first functional block and the second functional block are periodically re-divided. Adjust the area ratio and spatial distribution of the first and second functional blocks within the display area.

[0010] Furthermore, the step of configuring the light-transmitting area and heat dissipation channel within the LED transparent screen display area also includes: Based on the collaborative control signal generated for the second functional block, the operating power of the active cooling device is synchronously adjusted. The airflow direction of the active cooling device is aligned with the display area where the second functional block is located.

[0011] The present invention also provides a device for coordinated control of light transmittance and heat dissipation of a front-emitting LED transparent screen, comprising: The status acquisition module is used to acquire the real-time transmittance and real-time temperature of the LED transparent screen; The signal generation module is used to generate a coordinated control signal based on the transmittance deviation between the real-time transmittance and the target transmittance, and the temperature deviation between the real-time temperature and the target temperature. The control execution module is used to drive and control the independently addressable LED unit group in the LED transparent screen according to the cooperative control signal, and configure the light-transmitting area and heat dissipation channel in the display area of ​​the LED transparent screen.

[0012] The present invention also provides a computer device, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the steps of the above-described method for coordinated control of light transmittance and heat dissipation of a front-emitting LED transparent screen.

[0014] The present invention provides a method and apparatus for coordinated control of light transmittance and heat dissipation of a front-emitting LED transparent screen, which has the following beneficial effects: The present invention intelligently divides display and heat dissipation functional areas and implements high-frequency alternating switching control of LED units within the heat dissipation area. This allows local areas of the screen to be transformed into efficient physical heat dissipation channels in a very short time, thereby achieving a self-cooling effect of "the screen as a heat sink" without affecting the overall visual appeal. Simultaneously, the electronic drive control of the LEDs and the airflow control of the active heat dissipation duct are linked in a closed loop to achieve precise on-demand allocation of cooling resources, improving heat dissipation efficiency and energy utilization efficiency. The present invention effectively curbs local overheating and overall temperature rise, improving the optical stability, color consistency, and device lifespan of the screen under long-term high-brightness operation, fundamentally solving the thermal management problem of front-emitting LED transparent screens in high-performance application scenarios.

[0016] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0018] Reference Figure 1 The diagram below illustrates a method for coordinated control of light transmittance and heat dissipation in a front-emitting LED transparent screen, as proposed in this invention. The method includes the following steps: S1, obtain the real-time transmittance and real-time temperature of the LED transparent screen; S2, generate a coordinated control signal based on the transmittance deviation between the real-time transmittance and the target transmittance, and the temperature deviation between the real-time temperature and the target temperature; S3, based on the cooperative control signal, drive and control the independently addressable LED unit group in the LED transparent screen, and configure the light-transmitting area and heat dissipation channel in the display area of ​​the LED transparent screen.

[0019] In one embodiment, for step S1, The steps for obtaining the real-time transmittance and real-time temperature of an LED transparent screen include: Local illumination data is collected by photosensitive sensors deployed in the area of ​​each independently addressable LED unit group; Local temperature data is collected by temperature sensors located at the substrate positions corresponding to each independently addressable LED unit group; A weighted average calculation is performed on all the local illumination data and local temperature data to generate real-time transmittance and real-time temperature representing the overall state of the LED transparent screen.

[0020] In practical implementation, traditional overall monitoring methods cannot capture anomalies in local areas of the screen, leading to control lag or inaccuracy. This embodiment adopts a distributed, unitized data acquisition strategy: high-precision photosensitive sensors are deployed in the optical area of ​​each independently addressable LED unit group to collect local illumination data of each unit in real time; simultaneously, miniature temperature sensors are integrated on the driving substrate or heat dissipation base corresponding to each LED unit group to collect its local temperature data in real time. This design completely aligns the granularity of data acquisition with the granularity of control (i.e., independently addressable unit groups). Directly using hundreds or even thousands of discrete local data points is insufficient for effective macroscopic decision-making. Therefore, this embodiment further performs a physically-based weighted average calculation on all local illumination and temperature data. Specifically, the weighting coefficients can be preset according to factors such as the proportion of each unit group in the total area of ​​the display screen or the importance of its historical heat load. Through weighted average calculation, massive amounts of local data are fused to generate a single and reliable real-time transmittance value and real-time temperature value that can represent the overall state of the LED transparent screen, thereby eliminating control interference that may be caused by local instantaneous fluctuations.

[0021] In one embodiment, for step S2, The step of generating a coordinated control signal based on the transmittance deviation between the real-time transmittance and the target transmittance, and the temperature deviation between the real-time temperature and the target temperature, includes: The transmittance deviation and temperature deviation are used as input parameters and fed into a pre-trained multi-objective decision model. The multi-objective decision model outputs a comprehensive control command. The integrated control commands are converted into coordinated control signals that can be executed by the drive system.

[0022] In practical implementation, traditional methods typically employ simple threshold comparisons or independent PID controllers to handle transmittance and temperature separately. However, this approach fails to resolve the inherent physical contradiction between the two: increasing brightness (improving transmittance) often leads to increased temperature, while forced cooling (such as increasing fan speed) may not meet optical performance requirements. This control strategy struggles to achieve true synergy and optimization in dynamically changing usage scenarios. To address this fundamental technical challenge, this embodiment introduces a pre-trained multi-objective decision model. This model is not a simple logic controller but an intelligent decision-making core capable of understanding and learning the complex nonlinear relationship between transmittance and heat dissipation. Specifically, the transmittance deviation and temperature deviation calculated in step S1 are used as a set of input parameters and fed into the multi-objective decision model. The model is trained based on a large amount of historical operating data and internally encapsulates the thermal-optical coupling characteristics of the screen, enabling it to balance the magnitude and trend of the two deviations: for example, when the current temperature is acceptable but the transmittance is insufficient, the model tends to prioritize increasing brightness; while when the temperature approaches a safe threshold and the transmittance deviation is small, the model prioritizes initiating a cooling strategy. After complex internal calculations, the model ultimately outputs a comprehensive control command, which is mathematically a multi-dimensional vector that qualitatively and quantitatively indicates the direction and intensity of the next control step. Transforming the intelligent decision into specific actions that the hardware can execute requires a signal conversion process: the comprehensive control command output by the model is transmitted to a signal conversion module (usually implemented by the firmware within the driver chip). The module, according to preset mapping rules, parses and converts the command into specific coordinated control signals executable by the driver system. These signals contain finely programmed driving parameters (such as current value, duty cycle, etc.) for each independently addressable LED unit group in the subsequent step S3, arranged in time and space.

[0023] In one embodiment, the training steps of a pre-trained multi-objective decision model include: Acquire historical light transmittance data and historical temperature data of the LED transparent screen under various operating conditions; Establish a reward function that aims to minimize transmittance fluctuations and temperature fluctuations; By using reinforcement learning algorithms, the model is trained to learn and generate comprehensive control commands based on historical data and reward functions.

[0024] In practical implementation, acquiring historical transmittance and temperature data of the LED transparent screen under various operating conditions is fundamental to constructing a high-quality training dataset. These "various operating conditions" need to cover the screen's full range of operating states, from low-temperature startup and steady-state operation at room temperature to high-temperature peak load, and even combinations of different ambient light intensities and temperatures. During data acquisition, the screen's state at each moment (i.e., transmittance and temperature values) and the control actions performed in that state (such as driving signals applied to each LED unit group) must be recorded simultaneously, along with the state change at the next moment caused by these actions. This series of "state-action-new state" data pairs collectively constitutes the data teaching for the model to learn the screen's dynamic response characteristics. Subsequently, a reward function is established with the objective of minimizing transmittance and temperature fluctuations. This reward function (R) is typically designed to minimize transmittance deviation (et). T ) and temperature deviation (e t The negative penalty form of R can be expressed by the core structure as: R = - (w1* |e T | + w2 * |e t | + w3 * f overflow In this structure, w1 and w2 are two adjustable positive weighting coefficients, representing the system's emphasis on transmittance stability and heat dissipation performance, respectively. Their specific ratio needs to be calibrated through extensive experiments to reflect the product design's focus. overflow This is a severe penalty term for temperature exceeding limits. When the real-time temperature exceeds a certain safety threshold, this term increases sharply, forcing the model to prioritize heat dissipation safety. Through this function, the model is explicitly guided to find control strategies that simultaneously maintain high transmittance stability and low heat load. Finally, using reinforcement learning algorithms, the model is trained to learn and generate comprehensive control commands based on historical data and the reward function. Optionally, advanced reinforcement learning algorithms such as Deep Q-Network (DQN) or Proximal Policy Optimization (PPO) can be used. During training, the algorithm uses the aforementioned historical dataset as a replay library of its experience interacting with the environment. The model (as an agent) reads the "state" (i.e., the current transmittance and temperature) from the data at a given moment and then outputs an "action" (i.e., a preliminary control command). Based on the next "new state" recorded in the historical data and the reward function, the "reward" obtained by executing the action is calculated. Through iteration, the model continuously updates its internal neural network parameters, eventually learning an optimal policy (π): a mapping from any given "state" to the best "action".

[0025] In one embodiment, for step S3, The steps of driving and controlling the independently addressable LED unit groups in the LED transparent screen according to the coordinated control signal, and configuring the light-transmitting area and heat dissipation channel within the display area of ​​the LED transparent screen, include: Based on the collaborative control signal, the display area is dynamically divided into multiple functional blocks; Adjust the driving current of at least one LED unit group in the first functional block to maintain the display brightness of the first functional block; Adjust the driving current and switching frequency of the LED unit group in at least one second functional block so that the LED unit group in the second functional block alternates between the lit state and the off state.

[0026] In practical implementation, step S3 is responsible for converting the collaborative control signal generated in step S2 into physical control actions for the LED transparent screen. The key lies in dynamically reconstructing the "display" and "heat dissipation" functional areas on the two-dimensional display plane using a spatiotemporal multiplexing method. Specifically, based on the collaborative control signal, the display area of ​​the LED unit is dynamically divided into multiple functional blocks. This division is not a physical or fixed structural division, but rather a logical functional grouping of independently addressable LED unit groups on the screen based on the instructions contained in the collaborative control signal. For example, the system might divide the area currently requiring high-brightness display of the core image into a "first functional block," while dividing the area displaying static backgrounds or non-critical information into a "second functional block." This division is highly dynamic and updates in real time according to changes in the thermal load of the displayed content and the real-time temperature distribution of the screen, thereby achieving optimal resource scheduling. Differentiated driving strategies are applied to different functional blocks. For at least one primary functional block, the core task is to ensure a good visual experience. Therefore, the system adjusts the drive current of its internal LED unit groups to maintain the designed target display brightness, ensuring that the light transmittance and visual performance of the core image are not affected by heat dissipation management measures. For at least one secondary functional block, this block is assigned the function of a "heat dissipation channel." The drive current and switching frequency of the LED unit groups within the block are adjusted synchronously. Specifically, the drive current is appropriately reduced to decrease heat source power. Simultaneously, a specific control signal is applied to cause the LED unit groups in this block to alternate between on and off states at a frequency higher than the persistence of human vision (e.g., above 200Hz). During the brief "on" period, it performs some display functions; during the longer "off" period, the LED chips in this block stop emitting light and generating heat, instantly transforming into a highly transparent physical channel, allowing ambient light to penetrate to the maximum extent. The heat accumulated in the screen structure is quickly dissipated using natural convection or forced air cooling between the inside and outside of the screen. This high-frequency switching mechanism, which appears to the human eye as a stable display with slightly reduced brightness, creates a periodically existing "breathing window" in thermodynamics, enabling efficient heat dissipation. This embodiment, through dynamic zoning and differentiated driving technology, transforms the display panel itself into a dynamically reconfigurable "intelligent heat sink" without adding additional physical heat dissipation structures. Ultimately, it achieves coordinated configuration of the light-transmitting area and heat dissipation channels at the physical level, fundamentally solving the heat dissipation bottleneck and light transmittance maintenance problem of front-emitting LED transparent screens under high brightness.

[0027] In one embodiment, the step of dynamically dividing the display area into multiple functional blocks further includes: Based on real-time temperature changes, the first functional block and the second functional block are periodically re-divided. Adjust the area ratio and spatial distribution of the first and second functional blocks within the display area.

[0028] In practice, the first and second functional blocks are periodically re-divided based on real-time temperature changes. This process is performed at a fixed control cycle (e.g., several times per second). At the beginning of each control cycle, the temperature field data of the entire screen is re-acquired, and the layout of the functional blocks is recalculated and re-divided based on the latest thermal distribution status and the output of the decision model. This means that a certain area may be designated as the first functional block, responsible for the main display tasks, in the current cycle. However, if its temperature rises due to continuous operation in the next cycle, it may be dynamically adjusted to the second functional block, used for auxiliary heat dissipation, thereby achieving a uniform spatial distribution of heat load and avoiding localized overheating. Furthermore, during this process, the system dynamically adjusts the area ratio and spatial distribution of the first and second functional blocks within the display area. The adjustment logic is tightly coupled with real-time heat dissipation requirements: when the overall screen temperature is low, a larger area ratio is allocated to the first functional block (high-brightness display area) to maximize visual performance; as the overall or local temperature of the screen rises, the area ratio of the second functional block (heat dissipation channel area) will be gradually increased to enhance heat dissipation capacity. Simultaneously, the spatial distribution of the blocks is intelligently relocated based on the "hot zones" on the screen. For example, the system deliberately places the second functional blocks (heat dissipation channels) directly above the area with the highest real-time temperature to achieve precise "targeted heat dissipation"; or it arranges multiple dispersed small second functional blocks around the high-temperature area to form an effective heat dissipation enclosure. This coordinated dynamic adjustment of area and spatial position allows display and heat dissipation resources to be optimally allocated in the two-dimensional space of the screen, thereby maximizing heat dissipation efficiency while ensuring the visual integrity of the core display content.

[0029] In one embodiment, the step of configuring the light-transmitting area and heat dissipation channel within the LED transparent screen display area further includes: Based on the collaborative control signal generated for the second functional block, the operating power of the active cooling device is synchronously adjusted. The airflow direction of the active cooling device is aligned with the display area where the second functional block is located.

[0030] In practical implementation, the process of configuring the light-transmitting area and heat dissipation channel described in step S3 further maximizes heat dissipation efficiency through linkage control with external heat dissipation hardware. Specifically, it also includes synchronously adjusting the operating power of the active heat dissipation device based on the collaborative control signal generated for the second functional block. The active heat dissipation device, such as an axial fan or centrifugal fan, does not have its operating power (usually expressed as speed or voltage) set independently or continuously run at maximum power, but is deeply bound to the collaborative control of the LEDs inside the screen. When the collaborative control signal instructs a certain second functional block to enter the "heat dissipation mode" of a high-frequency switch, a specific channel of the signal will synchronously generate a corresponding speed adjustment command, which is sent to the drive circuit of the active heat dissipation device, increasing its operating power to a level that matches the heat dissipation requirements of that block; conversely, when the screen heat load decreases and the area of ​​the second functional block shrinks or disappears, the operating power of the heat dissipation device will also decrease accordingly, thereby achieving on-demand heat dissipation and reducing the overall energy consumption of the system. The airflow direction of the active heat dissipation device is designed to be aligned with the display area where the second functional block is located. This means that the cooling airflow generated by the heat dissipation device is not evenly blown across the entire back of the screen. Instead, through optimized airflow channels or physical layout, it forms one or more concentrated airflows that cover the screen area logically defined as a "heat dissipation channel." The advantage of this directional airflow is that when the LED unit group of the second functional block is in the "off" state, the LED chip in that area stops heating up and has the highest light transmittance. The cooling airflow can penetrate the screen structure without obstruction, directly and efficiently exchanging heat with the heat sources that most need cooling (such as LED driver chips and substrates). This synergistic effect of inside-out (LED switches create heat dissipation windows) and outside-in (directional airflow enhances convection) together forms an efficient thermal management closed loop, improving heat dissipation efficiency and ensuring that the screen can maintain stable optical performance and long lifespan even under high loads.
