Description

Technical Field

[0001] The present invention relates to the field of pulse technology, and in particular to a low-power signal transmission method for a glass-based display panel based on AM drive. Background Art

[0002] With the rapid development of information technology and the popularization of new display technologies, the power consumption of display devices has become a key bottleneck restricting the sustainable development of the industry. AM-driven glass-based display panels are widely used in high-end display fields such as Micro LED and OLED due to their advantages such as independent pixel control, low flicker, and high refresh rate. However, traditional AM driving technology has significant energy consumption problems during signal transmission. For example, signals are prone to attenuation during transmission on long-distance glass-based traces, and this attenuation is affected by multiple factors such as temperature, impedance, and trace structure. However, traditional solutions often ignore dynamic changes and rely only on static design redundancy, resulting in energy waste. In addition, traditional methods use a globally unified driving strategy and do not divide the core / non-core areas according to the trace length, temperature distribution, and functional requirements of the display panel. Therefore, only a roughly unified sleep strategy is adopted in power management, which cannot achieve regionalized, hierarchical, and intelligent low-power control.

[0003] In view of this, the present invention proposes a low-power signal transmission method for a glass-based display panel based on AM drive to solve the above problems. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art and achieve the above-mentioned objectives, the present invention provides the following technical solution: a low-power signal transmission method for a glass-based display panel based on AM drive, comprising:

[0005] Step SS1: Calculate the signal attenuation coefficient based on the equivalent circuit mechanism by collecting the trace parameters and ambient temperature data of the glass substrate; generate a trace layered region map based on the trace length; and generate a composite partition map based on the trace layered region map and the upper and lower temperature gradients, wherein the composite partition map includes N sub-regions.

[0006] Step SS2, temperature-attenuation-aware gamma voltage compensation: For each sub-region, the gamma voltage is compensated using a temperature and attenuation-aware method to obtain an optimized gamma voltage. The temperature and attenuation-aware method uses a directional attenuation compensation method based on the temperature coefficient and the actual signal attenuation coefficient to compensate the original gamma voltage to generate a compensated gamma voltage. Raised cosine pulse shaping technology is used to output the optimized gamma voltage.

[0007] Step SS3, load impedance prediction and pulse parameter optimization: Based on the optimized gamma voltage, calculate the current load impedance based on Ohm's law; combine historical load impedance data to classify it into low, medium, and high levels, and construct an impedance-pulse parameter mapping table; predict the load impedance through linear regression and pre-adjust the pulse parameters; and calculate the confidence level based on the residual and standard deviation of the predicted and actual load impedance;

[0008] Step SS4, adaptive sleep strategy triggering: set the upper and lower limits of the load impedance and the standard confidence level. If the predicted load impedance exceeds the upper and lower limits of the load impedance and the confidence level exceeds the standard confidence level, the leakage current evaluation is started in advance to calculate the predicted leakage current value, and the sleep state is triggered according to the predicted leakage current value; if the predicted leakage current value is less than A1, enter shallow sleep; if the predicted leakage current value is greater than A2, enter deep sleep; if the leakage current value is between A1 and A2, enter the non-sleep state.

[0009] Furthermore, the specific method of calculating the signal attenuation coefficient based on the dynamic equivalent circuit mechanism by collecting the wiring parameters and ambient temperature data of the glass substrate includes:

[0010] The trace parameters of the glass substrate include trace length, trace width, spacing, and material impedance; the current ambient temperature data is obtained through sensors;

[0011] According to the routing parameters of the glass substrate and the current ambient temperature data, a pre-stored routing database is queried to obtain equivalent circuit model parameters corresponding to the routing parameters of the glass substrate; the equivalent circuit model parameters include resistance, inductance, capacitance, and conductance;

[0012] Retrieving the resistance in the equivalent circuit model parameters corresponding to the routing parameters of the current glass-based display panel, and calculating the difference between the current ambient temperature data and the reference temperature data based on the resistance in the equivalent circuit model parameters to calculate the resistance under the current ambient temperature data;

[0013] The signal attenuation coefficient is calculated based on the resistance in the corresponding equivalent circuit model parameters and the resistance under the current ambient temperature data.

[0014] Furthermore, the routing layered area map is generated according to the routing length; and a composite differentiation map is generated based on the upper and lower temperature gradients on the basis of the routing layered area map. The specific manner in which the composite differentiation map includes N sub-areas includes:

[0015] Generate a temperature distribution heat map of the glass-based display panel using an infrared thermal imaging scanner. Each pixel in the temperature distribution heat map corresponds to a temperature value. Align the temperature distribution heat map with the axis length in the topology structure. Each pixel corresponds to a temperature value and a trace length.

[0016] The trace length refers to the actual trace path length from the signal source (such as the driver chip) to the pixel point (x, y);

[0017] Divide the glass-based display panel wiring length into core area, transition area and edge area, and generate a wiring layered area map;

[0018] The temperature averaging method is used to define the upper and lower temperature gradients, and the temperature values ​​in the temperature distribution heat map are divided into high temperature, medium temperature, and low temperature based on the upper and lower temperature gradients. The temperature averaging method is as follows: the average value is calculated based on all temperature values ​​in the temperature distribution heat map to obtain the temperature average value, and the upper and lower temperature gradients are defined based on the temperature average value and adjustable parameters.

[0019] Based on the routing layered area map, the core area is divided into a low-temperature core area and a medium-temperature core area according to the temperature gradient; the transition area is divided into a low-temperature transition area, a medium-temperature transition area, and a high-temperature transition area; the edge area is divided into a medium-temperature edge area and a high-temperature edge area, and a composite area map is generated, including N sub-areas;

[0020] Furthermore, for each sub-region, the gamma voltage is compensated using the temperature and attenuation sensing method to obtain the optimized gamma voltage, which includes:

[0021] The temperature coefficient of each sub-region is obtained by weighting the temperature value corresponding to the pixel point of each sub-region;

[0022] Calculate the actual signal attenuation coefficient of each pixel based on the signal attenuation coefficient of each pixel and the trace length;

[0023] For the original gamma voltage corresponding to each pixel, a directional attenuation compensation method is used to compensate the original gamma voltage of each pixel to obtain a compensated gamma voltage;

[0024] The directional attenuation compensation method calculates the compensated gamma voltage of the original gamma voltage of each pixel based on the temperature coefficient and the actual signal attenuation coefficient. This method introduces a temperature coefficient, which represents the temperature influence of the sub-region where each pixel is located. The temperature coefficient of each sub-region is different, and is combined with the actual signal attenuation coefficient, that is, the cumulative effect of signal attenuation suffered by the point, to adjust the original gamma voltage and obtain the compensated gamma voltage.

[0025] Based on the compensated gamma voltage, the optimized gamma voltage is output through the raised cosine pulse shaping technology.

[0026] Furthermore, the method of calculating the current load impedance based on the optimized gamma voltage and Ohm's law; dividing the load impedance data into low, medium and high levels in combination with historical load impedance data, and constructing an impedance-pulse parameter mapping table; predicting the load impedance and pre-adjusting the pulse parameters through linear regression; and calculating the confidence level based on the residual and standard deviation between the predicted and actual load impedances includes:

[0027] Based on the optimized gamma voltage and current, the current load impedance is calculated according to Ohm's law;

[0028] Classification is carried out based on historical load impedance; it is divided into low level, medium level and high level; low level is , the middle level is , high level ;

[0029] Constructing an impedance-pulse parameter mapping table;

[0030] The historical load impedance is used as input to obtain the predicted load impedance using linear regression method;

[0031] According to the current load impedance, the corresponding adjustment pulse parameters, i.e., the adjustment duty cycle and the adjustment frequency, are obtained from the impedance-pulse parameter mapping table;

[0032] Pre-adjusting the adjustment pulse parameters using the predicted load impedance to obtain pre-adjusted pulse parameters;

[0033] A residual is calculated based on the difference between the predicted load impedance and the actual load impedance; a standard deviation of the residual is calculated, and a confidence level is calculated based on the residual and the standard deviation of the residual.

[0034] Furthermore, the specific method of constructing the impedance-pulse parameter mapping table includes:

[0035] The load impedance, load impedance change rate, optimized gamma voltage and current are used as inputs, and a genetic algorithm is used to find the optimal solution for each load impedance. The optimal solution is the pulse parameter.

[0036] Adjust the optimal solution according to the level corresponding to the load impedance. If the load impedance is at a low level, use the ambient temperature data to compensate for the optimal solution to obtain the compensated optimal solution, which is the adjusted optimal solution at the low level.

[0037] If the load impedance is at a medium level, the optimal solution is compensated using the working time of the glass-based display panel to obtain the compensated optimal solution, i.e., the optimal solution for adjustment at a medium level.

[0038] If the load impedance is at a high level, the adjusted drive voltage is calculated using the ambient temperature data and the drive voltage, and the adjusted drive voltage is used to compensate the optimal solution to obtain the compensated optimal solution, i.e., the adjusted optimal solution at the high level.

[0039] Construct an impedance-pulse vector based on the load impedance and its corresponding adjustment pulse parameters;

[0040] An impedance-pulse parameter mapping table is constructed from M impedance-pulse vectors;

[0041] If the load impedance is not found in the impedance-pulse parameter mapping table, a linear interpolation method is used to calculate the optimal adjustment solution corresponding to the load impedance.

[0042] Furthermore, the load impedance upper and lower limits and standard confidence levels are set. If the predicted load impedance exceeds the upper and lower limits of the load impedance and the confidence level exceeds the standard confidence level, the leakage current evaluation is started in advance to calculate the predicted leakage current value. The specific method of triggering the sleep state according to the predicted leakage current value includes:

[0043] If the predicted load impedance reaches the upper limit of the load impedance and the confidence level exceeds the standard confidence level, the leakage current assessment is started in advance to calculate the predicted leakage current value. If the predicted leakage current value is less than A1, a shallow sleep state is entered. If the predicted leakage current value is greater than A2, a deep sleep state is entered. If the predicted leakage current value is between A1 and A2, the sleep state is not entered.

[0044] If the predicted load impedance does not reach the upper limit of the load impedance and the confidence level does not exceed the standard confidence level, monitoring will continue;

[0045] When entering the shallow sleep state, the row and column drive clock signals and data lines of the non-core area are physically disconnected from the drive voltage, stopping energy consumption; the core area reduces power consumption by dynamically reducing the standard refresh rate and standard drive voltage;

[0046] When entering the deep sleep state, the row and column drive clock signals and data lines of the non-core area are physically disconnected from the drive voltage; the refresh rate of the core area is reduced to zero, the drive voltage is reduced to the lowest safe value, the glass-based display panel refresh is stopped, and the system enters the lowest power consumption state, basically only maintaining necessary data storage and state preservation;

[0047] When not entering the sleep state, the core area and non-core areas operate normally. The core area uses a standard refresh frequency and standard drive voltage to ensure smooth display of the display panel and high response speed of signal transmission, while the non-core area continues to receive and process row and column drive clock signals to ensure normal transmission of display data. It is in a high power consumption state to meet the real-time display panel update and response requirements, and no power consumption optimization is performed.

[0048] Furthermore, when entering the shallow sleep state, the row and column drive clock signals and data lines of the non-core area are physically disconnected from the drive voltage, stopping energy consumption; the core area reduces power consumption by dynamically reducing the standard refresh rate and standard drive voltage. Specific methods include:

[0049] The glass-based display panel includes a low-temperature core area, a medium-temperature core area, a low-temperature transition area, a medium-temperature transition area, a high-temperature transition area, a medium-temperature edge area, and a high-temperature edge area; the low-temperature core area and the medium-temperature core area are defined as core areas; the low-temperature transition area, the medium-temperature transition area, the high-temperature transition area, the medium-temperature edge area, and the high-temperature edge area are defined as non-core areas;

[0050] In the non-core area, the clock signals of the row and column drivers of the non-core area are disconnected through gate-controlled switches (such as MOSFETs). Low-leakage MOS switches are used to physically disconnect the data lines in the non-core area from the drive voltage, and pull-up resistors are applied to the disconnected data lines to prevent repeated charging and discharging caused by level drift.

[0051] In the core area, the standard driving voltage of the core area is dynamically reduced through the standard refresh rate, and the power consumption is reduced based on the reduced refresh rate and driving voltage, and low-power transmission is performed; among them, the timing signal is parsed through the display interface protocol and the refresh rate is directly read.

[0052] Furthermore, when entering the deep sleep state, the row and column drive clock signals and data lines of the non-core area are physically disconnected from the drive voltage; the refresh rate of the core area is reduced to zero, the drive voltage is reduced to the lowest safe value, and the glass-based display panel refresh is stopped. The specific method of entering the lowest power consumption state includes:

[0053] When entering deep sleep, for the non-core area, the clock signals of the row drive and column drive are disconnected, and the data lines and drive voltage of the non-core area are disconnected; for the core area, the refresh rate is reduced to 0, and the drive voltage is reduced to the lower limit of the safe drive voltage, so that the display panel no longer refreshes and enters the lowest power consumption state.

[0054] Furthermore, when not in the sleep state, the core area and the non-core area may perform normal operations in a specific manner including:

[0055] When not in sleep mode, the core and non-core areas are continuously refreshed and operate normally without power consumption optimization.

[0056] The core area continues to operate at a standard refresh rate and standard driving voltage to ensure the response speed and display clarity of image processing and signal transmission.

[0057] The non-core area keeps the clock signals of the row driver and the column driver running, while the data lines continue to be connected to the driving voltage for normal transmission and display of image data in the display panel.

[0058] The technical effects and advantages of the low-power signal transmission method for glass-based display panels based on AM drive of the present invention are as follows:

[0059] The present invention utilizes collected trace parameters (such as length, width, impedance, etc.) and real-time temperature data, and based on a dynamic equivalent circuit model, can dynamically perceive signal attenuation behavior, thereby improving adaptability and accuracy to environmental changes.

[0060] Through a combined analysis of routing layering and temperature distribution, the display panel is divided into multiple sub-areas (such as a low-temperature core area and a high-temperature edge area), breaking the traditional "one-size-fits-all" regional management model and laying the foundation for subsequent refined driving and power consumption control.

[0061] Directional attenuation compensation is introduced to perform gamma voltage compensation on each pixel. By combining the actual signal attenuation coefficient at that pixel with the temperature coefficient of the area in which it is located, the drive voltage is precisely adjusted to ensure image quality while avoiding overpowering. Raised cosine pulse shaping technology is also used to optimize the output waveform, reduce high-frequency signal spikes, improve signal transmission efficiency, and reduce losses.

[0062] Through linear regression and confidence assessment mechanisms, load impedance is predicted in real time, and adjustment strategies are screened to achieve early intervention and precise matching, improving system energy efficiency and operational stability.

[0063] When the predicted load impedance and confidence level reach a threshold, leakage current assessment is immediately initiated and the system decides whether to enter deep sleep, light sleep, or remain active based on the predicted value. This provides a smarter response and more proactive energy saving compared to traditional sleep modes based solely on "time and user operation."

[0064] When in shallow sleep mode, the non-core area signals are physically disconnected, and the core area maintains a low refresh rate and low drive voltage, reducing power consumption while maintaining some display performance.

[0065] When in deep sleep mode, the core area also stops refreshing and reduces the driving voltage to a safe lower limit, achieving the lowest power consumption state for the entire screen.

[0066] When not in sleep mode, the system maintains standard drive parameters to ensure the display panel's image quality and response speed. Meanwhile, the gamma voltage and pulse parameters optimized in the previous steps remain in effect, prioritizing performance while also taking energy saving into account.

[0067] From front-end signal conditioning and load impedance prediction to back-end sleep management, the entire chain is collaboratively optimized to form a closed-loop energy-saving system. It also integrates AI perception (predicted impedance), big data (historical load), intelligent strategies (dynamic sleep) and circuit regulation to improve the intelligent operation level of the display system. It solves the problems of traditional AM driving such as ignoring routing differences, temperature influence, slow dynamic response, and rough sleep strategy. It significantly reduces the overall energy consumption of the panel, extends the service life of the equipment, and provides a reliable low-power solution for high-resolution and wide-temperature range application scenarios.

[0071] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0072] Example 1

[0073] See also Figure 1 As shown, the low-power signal transmission method for a glass-based display panel based on AM drive in this embodiment includes:

[0074] Step SS1: Calculate the signal attenuation coefficient based on the equivalent circuit mechanism by collecting the trace parameters and ambient temperature data of the glass substrate; generate a trace layered region map based on the trace length; and generate a composite partition map based on the trace layered region map and the upper and lower temperature gradients, wherein the composite partition map includes N sub-regions.

[0075] Step SS2, temperature-attenuation-aware gamma voltage compensation: For each sub-region, the gamma voltage is compensated using a temperature and attenuation-aware method to obtain an optimized gamma voltage. The temperature and attenuation-aware method uses a directional attenuation compensation method based on the temperature coefficient and the actual signal attenuation coefficient to compensate the original gamma voltage to generate a compensated gamma voltage. Raised cosine pulse shaping technology is used to output the optimized gamma voltage.

[0076] Step SS3, load impedance prediction and pulse parameter optimization: Based on the optimized gamma voltage, calculate the current load impedance based on Ohm's law; combine historical load impedance data to classify it into low, medium, and high levels, and construct an impedance-pulse parameter mapping table; predict the load impedance through linear regression and pre-adjust the pulse parameters; and calculate the confidence level based on the residual and standard deviation of the predicted and actual load impedance;

[0077] Step SS4, adaptive sleep strategy triggering: set the upper and lower limits of the load impedance and the standard confidence level. If the predicted load impedance exceeds the upper and lower limits of the load impedance and the confidence level exceeds the standard confidence level, the leakage current evaluation is started in advance to calculate the predicted leakage current value, and the sleep state is triggered according to the predicted leakage current value; if the predicted leakage current value is less than A1, enter shallow sleep; if the predicted leakage current value is greater than A2, enter deep sleep; if the leakage current value is between A1 and A2, enter the non-sleep state.

[0078] By collecting the glass substrate's trace parameters and ambient temperature data and based on the equivalent circuit mechanism, the specific method for calculating the signal attenuation coefficient includes the following:

[0079] The trace parameters of the glass substrate include trace length, trace width, spacing, and material impedance. The trace length, trace width, and spacing are automatically extracted during the circuit design phase of the glass-based display panel when using EDA software for layout design by parsing GDSII and Gerber file formats.

[0080] The material impedance is obtained in real time by using an impedance analyzer;

[0081] Get the current ambient temperature data through the temperature sensor;

[0082] Based on the trace parameters of the glass substrate and the current ambient temperature data (trace length, trace width, spacing, material impedance), the pre-stored trace database is queried to obtain the equivalent circuit model parameters corresponding to the trace parameters of the glass substrate; the equivalent circuit model parameters include resistance, inductance, capacitance, and conductance;

[0083] The pre-stored routing database covers equivalent circuit characteristics under different routing lengths, widths, spacings, material impedances, and temperature conditions, including resistance, inductance, capacitance, and conductance parameters. Each record in the database corresponds to a routing configuration and its electrical response under specific environmental conditions. Using index matching, the dynamic equivalent parameters of any routing structure under the current temperature environment can be quickly obtained, supporting real-time modeling of signal transmission and energy consumption analysis.

[0084] For example, the collected glass substrate trace parameters are: trace length 1, trace width 2, spacing 3, and material impedance 4; retrieve the equivalent circuit model parameters corresponding to trace length 1, trace width 2, spacing 3, and material impedance 4 from the pre-stored trace database;

[0085] The resistance in the equivalent circuit model parameters corresponding to the routing parameters of the current glass-based display panel is retrieved. Based on the resistance in the equivalent circuit model parameters, the difference between the current ambient temperature data and the reference temperature data is calculated to calculate the resistance under the current ambient temperature data. The formula is: ,in, is the length resistance, is the temperature coefficient, For reference ambient temperature data (25°C), It is the length resistance under the current ambient temperature data;

[0086] Calculate the signal attenuation coefficient based on the resistance in the corresponding equivalent circuit model parameters and the resistance under the current ambient temperature data;

[0087] The signal attenuation coefficient can be calculated based on the resistance in the equivalent circuit model parameters and the resistance at the current ambient temperature data because resistance is one of the key parameters that affects the degree of signal attenuation in the transmission line. In the equivalent circuit model, the resistance of the trace changes with temperature (usually increasing with rising temperature), which directly affects the energy loss of the signal during transmission. By comparing the equivalent resistance at the reference temperature with the corrected resistance at the current temperature, the degree of change in signal transmission loss can be reflected.

[0088] The equivalent circuit model is a common method in existing technologies and is widely used in circuit design and signal transmission analysis. In this model, the various elements of a physical circuit (such as resistance, inductance, capacitance, and conductance) are treated as idealized electrical components to simplify the analysis of actual circuits. For traces on glass substrates, the equivalent circuit model accurately describes the electrical characteristics of signals transmitted along the trace by converting the trace's geometry (such as length, width, and spacing) and material properties (such as impedance) into corresponding electrical parameters (such as resistance, inductance, capacitance, and conductance). This method can help designers understand phenomena such as attenuation and reflection during signal transmission, providing a basis for optimizing signal quality and reducing power consumption.

[0089] Traditional approaches typically employ globally unified design redundancy, relying on the same transmission strategy across all regions. This ignores the actual differences between different regions (such as core and edge areas). Regardless of signal transmission distance or temperature, the same strategy is applied across all regions, often resulting in excessive power consumption in some areas while wasting power in others.

[0090] Generate a routing layered area map based on the routing length; generate a composite partition map based on the upper and lower temperature gradients based on the routing layered area map. The specific methods of including N sub-areas in the composite partition map include:

[0091] Generate a temperature distribution heat map of the glass-based display panel using an infrared thermal imaging scanner. Each pixel in the temperature distribution heat map corresponds to a temperature value. Align the temperature distribution heat map with the axis length in the topology structure. Each pixel corresponds to a temperature value and a trace length.

[0092] The trace length refers to the actual trace path length from the signal source (such as the driver chip) to the pixel point (x, y);

[0093] The trace length of the glass-based display panel is divided into the core area, transition area and edge area to generate a trace layered area map. Here, the k-means clustering algorithm can be used to take the trace length as input to obtain three clusters, corresponding to the trace length of the three intervals. The core area, transition area and edge area are divided according to the trace length.

[0094] The temperature averaging method is used to define the upper and lower temperature gradients, and the temperature values ​​in the temperature distribution heat map are divided into high temperature, medium temperature, and low temperature based on the upper and lower temperature gradients. The temperature averaging method is as follows: the average value is calculated based on all temperature values ​​in the temperature distribution heat map to obtain the temperature average value, and the upper and lower temperature gradients are defined based on the temperature average value and adjustable parameters.

[0095] Based on the routing layered area map, the core area is divided into a low-temperature core area and a medium-temperature core area according to the temperature gradient; the transition area is divided into a low-temperature transition area, a medium-temperature transition area, and a high-temperature transition area; the edge area is divided into a medium-temperature edge area and a high-temperature edge area, and a composite area map is generated, including N sub-areas;

[0096] In display panels, the resistance of traces is affected by the panel temperature. Higher temperatures increase resistance, leading to more severe signal attenuation. Using the same signal transmission strategy in high-temperature areas can exacerbate signal attenuation, impacting display quality and power consumption. By carefully categorizing temperatures, different signal transmission strategies can be adopted for different temperature zones, achieving optimal results.

[0097] Different trace lengths, temperatures, and signal transmission characteristics determine the signal transmission requirements of each area in the display panel. By dividing the display panel into core, transition, and edge areas, more precise optimization can be performed based on the needs of each area. The core area may require higher signal quality, while the transition and edge areas may have relatively lower requirements. This regional management can effectively reduce unnecessary energy waste.

[0098] Temperature changes may not be uniform across the entire display panel. By dynamically dividing the areas based on the temperature gradient, the signal transmission strategy for each area can be adjusted more accurately, avoiding a unified static processing method and ensuring that the system is optimized based on actual temperature conditions.

[0099] For each sub-region, the gamma voltage is compensated using temperature and attenuation sensing. The optimized gamma voltage is obtained by:

[0100] The temperature coefficient of each sub-region is obtained by weighting the temperature value corresponding to the pixel point of each sub-region;

[0101] Calculate the actual signal attenuation coefficient of each pixel based on the signal attenuation coefficient of each pixel and the trace length;

[0102] For the original gamma voltage corresponding to each pixel, the directional attenuation compensation method is used to compensate the original gamma voltage of each pixel to obtain the compensated gamma voltage. The formula is: ,in, Pixel The original gamma voltage signal, Pixel The compensation gamma voltage, Pixel The temperature coefficient of the corresponding sub-region, is the actual signal attenuation coefficient;

[0103] The directional attenuation compensation method calculates a compensated gamma voltage based on the temperature coefficient and the actual signal attenuation coefficient of the original gamma voltage of each pixel. This method introduces a temperature coefficient that represents the temperature influence of the sub-region where each pixel is located. The temperature coefficient of each sub-region is different. The original gamma voltage is adjusted in combination with the actual signal attenuation coefficient, that is, the cumulative effect of signal attenuation at that point, to obtain the compensated gamma voltage.

[0104] Based on the compensated gamma voltage, the optimized gamma voltage is output through the raised cosine pulse shaping technology;

[0105] Raised cosine pulse shaping (RCP) is a signal optimization technique widely used in digital communications. It reduces inter-symbol interference (ISI) and optimizes spectrum usage by designing a pulse signal with a limited bandwidth. This technique uses a pulse shaped like a raised cosine function in the frequency domain to adjust the signal's roll-off factor and smooth the signal waveform, thereby reducing interference and distortion during transmission and improving the signal's noise immunity. In display panel technology, the application of RCP can effectively optimize gamma voltage output, ensuring signal transmission accuracy and image quality, and reducing display issues caused by signal interference or noise.

[0106] An independent temperature coefficient is introduced for each sub-area to reflect its actual current thermal state; combined with the pixel-level trace length and signal attenuation coefficient, "tailor-made" voltage compensation is achieved for each pixel. Instead of a global one-size-fits-all approach, graded compensation is performed based on the differences in physical properties of different areas of the display panel, significantly improving accuracy.

[0107] Based on the optimized gamma voltage, the current load impedance is calculated based on Ohm's law. The load impedance data is combined with historical data to classify the load impedance into low, medium, and high levels, and an impedance-pulse parameter mapping table is constructed. The load impedance is predicted through linear regression and the pulse parameters are pre-adjusted. The confidence level is calculated based on the residual and standard deviation between the predicted and actual load impedances. The specific methods include:

[0108] Based on the optimized gamma voltage and current, the current load impedance is calculated according to Ohm's law;

[0109] Classification is carried out based on historical load impedance; it is divided into low level, medium level and high level; low level is , the middle level is , high level ,in, is the load impedance, and The upper and lower limits of the standard load impedance are set by empirical method;

[0110] Constructing an impedance-pulse parameter mapping table;

[0111] The historical load impedance is used as input to obtain the predicted load impedance using linear regression method;

[0112] According to the current load impedance, the corresponding adjustment pulse parameters, i.e., the adjustment duty cycle and the adjustment frequency, are obtained from the impedance-pulse parameter mapping table;

[0113] The adjustment pulse parameters are pre-adjusted using the predicted load impedance to obtain the pre-adjusted pulse parameters; the formula is: ,in, and To pre-adjust the pulse parameters, To predict the load impedance, and The frequency and duty cycle of the adjustment are obtained from the impedance-pulse parameter mapping table;

[0114] The residual is calculated based on the difference between the predicted load impedance and the actual load impedance; the standard deviation of the residual is calculated, and the confidence level is calculated based on the residual and the standard deviation of the residual. The formula is: ,in, represents the residual, represents the standard deviation of the residuals, is the confidence level;

[0115] Predictive fine-tuning is performed by predicting the impedance to pre-adjust the pulse parameters; in fact, it predicts the future load impedance and its corresponding adjustment pulse parameters;

[0116] By predicting the load impedance and pre-adjusting the pulse parameters, the adaptive optimization of pulse parameters (such as frequency and duty cycle) is achieved in advance, thereby significantly improving the matching and energy efficiency of the driving signal. Unlike traditional methods that only rely on fixed pulse settings or empirical redundant design, this solution first uses the optimized gamma voltage and current to dynamically calculate the current load impedance, and combines historical data for grading and regression prediction, and then realizes personalized parameter matching through the constructed impedance-pulse parameter mapping table. At the same time, a residual-confidence evaluation mechanism is introduced to ensure the reliability of the prediction results.

[0117] The specific methods of constructing the impedance-pulse parameter mapping table include:

[0118] The load impedance, load impedance change rate, optimized gamma voltage and current are used as inputs, and a genetic algorithm is used to find the optimal solution for each load impedance. The optimal solution is the pulse parameter.

[0119] The optimal solution is adjusted according to the level corresponding to the load impedance. If the load impedance is at a low level, the optimal solution is compensated using the ambient temperature data to obtain the compensated optimal solution, which is the optimal solution for adjustment at the low level. The formula is: ,in, is the optimal solution in the lower level, is the optimal solution for regulation in the low level, is the ambient temperature data, 0.002 is the temperature compensation coefficient, and 25 is the reference ambient temperature data;

[0120] If the load impedance is medium, the optimal solution is compensated using the working time of the glass-based display panel to obtain the compensated optimal solution, that is, the optimal solution for regulation in the medium level; the formula is: ,in, is the optimal solution in the middle level, is the optimal solution for regulation in the middle level, is the working time of the glass-based display panel, 0.05 is the aging compensation factor and 1000 is the reference time;

[0121] If the load impedance is high, the ambient temperature data and the drive voltage are used to calculate the adjusted drive voltage, and the adjusted drive voltage is used to compensate the optimal solution to obtain the compensated optimal solution, that is, the adjusted optimal solution in the high level. The formula for the adjusted drive voltage is: ,in, is the driving voltage, The adjusted drive voltage is 0.01, the drive voltage derating factor is 60, and the critical ambient temperature data is 60. The formula for the optimal solution for high-level regulation is: ;Adjusting the optimal solution means adjusting the pulse parameters;

[0122] Construct an impedance-pulse vector based on the load impedance and its corresponding adjustment pulse parameters;

[0123] An impedance-pulse parameter mapping table is constructed from M impedance-pulse vectors;

[0124] If the load impedance is not found in the impedance-pulse parameter mapping table, the linear interpolation method is used to calculate the optimal adjustment solution corresponding to the load impedance;

[0125] It can achieve refined and customized adjustment of pulse parameters under different load impedance states, and ensure that the pulse parameters have global optimal performance by introducing genetic algorithms for global optimization. At the same time, it dynamically compensates the optimal solution by combining multi-dimensional factors such as ambient temperature, panel working time and driving voltage, making the mapping table highly adaptable and real-time. In addition, by constructing an impedance-pulse vector and linear interpolation mechanism, it ensures that effective pulse parameters can be obtained quickly and continuously under any load state, thereby improving the overall response speed, accuracy and energy efficiency control capabilities of the system.

[0126] Traditional methods typically employ a globally unified sleep strategy or static threshold trigger mechanism, ignoring differences in wiring structure, thermal distribution, and functional importance across the panel. This coarse-grained management approach is prone to two types of problems: false triggering (i.e., entering sleep mode in non-critical situations, impacting display performance); and hysteresis triggering (i.e., failing to respond promptly to high power consumption states, resulting in continuously elevated energy consumption). Furthermore, traditional methods lack a prediction-based and confidence-based judgment mechanism, resulting in inflexible and forward-looking control. They are unable to dynamically adapt to changing operating conditions, resulting in significant lag and inefficiency in modern high-resolution, high-refresh-rate display panels.

[0127] Set the upper and lower limits of load impedance and the standard confidence level. If the predicted load impedance exceeds the upper and lower limits and the confidence level exceeds the standard confidence level, the leakage current evaluation is started in advance to calculate the predicted leakage current value. The specific methods for triggering the sleep state based on the predicted leakage current value include:

[0128] If the predicted load impedance reaches the upper limit of the load impedance and the confidence level exceeds the standard confidence level, the leakage current assessment is started in advance and the predicted leakage current value is calculated. The formula is: , where k is a constant, is the temperature regulation coefficient, is the aging influence coefficient; To predict the leakage current value; if the predicted leakage current value is less than A1, shallow sleep is performed; if the predicted leakage current value is greater than A2, deep sleep is performed; if the predicted leakage current value is between A1 and A2, sleep is not performed; the load impedance upper limit and standard confidence level are obtained through the expert method;

[0129] When entering the shallow sleep state, the row and column drive clock signals and data lines of the non-core area are physically disconnected from the drive voltage, stopping energy consumption; the core area reduces power consumption by dynamically reducing the standard refresh rate and standard drive voltage;

[0130] When entering the deep sleep state, the row and column drive clock signals and data lines of the non-core area are physically disconnected from the drive voltage; the refresh rate of the core area is reduced to zero, the drive voltage is reduced to the lowest safe value, the glass-based display panel refresh is stopped, and the system enters the lowest power consumption state, basically only maintaining necessary data storage and state preservation;

[0131] When not in sleep mode, the core and non-core areas operate normally. The core area uses a standard refresh rate and standard drive voltage to ensure smooth display of the display panel and high response speed of signal transmission, while the non-core area continues to receive and process row and column drive clock signals to ensure normal transmission of display data. It is in a high power consumption state to meet the real-time display panel update and response requirements, and no power consumption optimization is performed.

[0132] An adaptive sleep control mechanism based on load impedance prediction and confidence assessment is implemented, which is highly intelligent and targeted. By setting reasonable upper and lower limits and confidence thresholds for load impedance, it can effectively identify areas that are truly in abnormal or overloaded states, evaluate and predict leakage current in advance, and selectively enter shallow or deep sleep, greatly improving the accuracy and real-time performance of energy management. In addition, the sleep state distinguishes between core areas and non-core areas, which not only ensures the continuous operation of key functions of the panel, but also avoids the waste of resources in non-essential areas, and realizes the coordinated optimization of local sleep + dynamic power consumption reduction.

[0133] When entering the shallow sleep state, the row and column drive clock signals and data lines of the non-core area are physically disconnected from the drive voltage, stopping energy consumption. The core area reduces power consumption by dynamically reducing the standard refresh rate and standard drive voltage. The specific methods include:

[0134] The glass-based display panel includes a low-temperature core area, a medium-temperature core area, a low-temperature transition area, a medium-temperature transition area, a high-temperature transition area, a medium-temperature edge area, and a high-temperature edge area; the low-temperature core area and the medium-temperature core area are defined as core areas; the low-temperature transition area, the medium-temperature transition area, the high-temperature transition area, the medium-temperature edge area, and the high-temperature edge area are defined as non-core areas;

[0135] In the non-core area, the clock signals of the row and column drivers of the non-core area are disconnected through gate-controlled switches (such as MOSFETs). Low-leakage MOS switches are used to physically disconnect the data lines in the non-core area from the drive voltage, and pull-up resistors are applied to the disconnected data lines to prevent repeated charging and discharging caused by level drift.

[0136] In the core area, the standard driving voltage of the core area is dynamically reduced through the standard refresh rate, and the power consumption is reduced based on the reduced refresh rate and driving voltage, thereby performing low-power transmission; wherein, the timing signal is parsed through the display interface protocol to directly read the refresh rate;

[0137] For example, when entering light sleep mode, the standard refresh rate needs to be reduced from 120Hz to 30Hz. When the standard refresh rate is 120Hz, the standard drive voltage is 15V. When the refresh rate is reduced to 30Hz, the drive voltage is obtained by multiplying the ratio of 30Hz to 120Hz by the standard drive voltage of 15V to obtain the drive voltage when the refresh rate is reduced to 30Hz, which is 10.6V. The power consumption at this time is calculated by the capacitance, the square of the reduced drive voltage of 10.6V, and the refresh rate of 30Hz, where the capacitance is obtained by the capacitive sensor.

[0138] The row and column drive clock signals are key signals for synchronously controlling the refresh of pixel rows and columns in glass-based display panels. The row drive clock signal controls the scanning timing of a row of pixels through the horizontal synchronization signal (HSYNC), ensuring that each row of pixels is refreshed sequentially. The column drive clock signal coordinates data transmission in the column direction through the synchronization clock (CLK), ensuring that the pixel columns receive the correct data during each row refresh process.

[0139] In the shallow sleep state, these clock signals are disconnected through gate switches (such as MOSFETs), so that the row and column drive circuits in the non-core area stop working, thereby cutting off energy consumption;

[0140] The data line connects the driver chip and the pixel unit, carrying the actual image signal input. When the data line is disconnected from the driving voltage, it is equivalent to cutting off the data path for pixel update, thereby achieving power consumption control and signal shutdown in the corresponding area;

[0141] By dividing the display panel into core and non-core areas, differentiated management can be implemented based on the importance and working status of different areas, avoiding image delays or response lags caused by global unified sleep mode.

[0142] Gated MOSFETs are used to disconnect the row and column drive clock and data lines in the non-core area from the drive voltage, and pull-up resistors are used to prevent level drift, achieving true "physical isolation" and completely cutting off sources of invalid power consumption. The core area is not directly powered off, but the refresh rate and drive voltage are dynamically reduced by analyzing the timing signals to achieve minimum power consumption output while maintaining basic display performance, ensuring smooth display and user experience.

[0143] When entering the deep sleep state, the row and column drive clock signals and data lines of the non-core area are physically disconnected from the drive voltage; the refresh rate of the core area is reduced to zero, the drive voltage is reduced to the minimum safe value, and the glass-based display panel is stopped from refreshing. The specific method of entering the lowest power consumption state includes:

[0144] When entering deep sleep, the clock signals of the row and column drivers are disconnected for the non-core areas, as well as the data lines and drive voltages in the non-core areas. For the core areas, the refresh rate is reduced to 0, and the drive voltage is reduced to the lower limit of the safe drive voltage, so that the display panel no longer refreshes and enters the lowest power consumption state.

[0145] By reducing the refresh rate of the core area to 0, lowering the driving voltage to a safe lower limit, and completely disconnecting the driving and data circuits in the non-core area, the entire panel enters a static state, maintaining only the necessary data retention and state preservation, and reducing power consumption to almost the theoretical minimum;

[0146] Use physical-level disconnection (such as MOS switches disconnecting signals and voltages) to completely cut off all energy consumption channels in non-working areas, avoiding any form of leakage or standby energy consumption;

[0147] Although the driving voltage drops to the lowest level, it still remains above the "safe driving voltage lower limit", ensuring that circuit components are not damaged. At the same time, by maintaining the necessary data status, it prevents the device from entering a freeze or reinitialization state. It is especially suitable for situations such as long-term standby, no signal input, and nighttime use, achieving an "automatic freeze + extreme energy saving" state, extending equipment life and reducing heat accumulation.

[0148] When not in hibernation, the core and non-core areas perform their normal operations as follows:

[0149] When not in sleep mode, the core and non-core areas are continuously refreshed and operate normally without power consumption optimization.

[0150] The core area continues to operate at a standard refresh rate and standard driving voltage to ensure the response speed and display clarity of image processing and signal transmission.

[0151] The non-core area keeps the row and column drive clock signals running, while the data lines continue to be connected to the drive voltage for normal transmission and display of image data in the display panel.

[0152] The core area operates at a standard refresh rate and standard drive voltage, ensuring accurate color reproduction, uniform brightness, and no image smearing, ensuring a high-quality visual experience.

[0153] The non-core area continuously receives and transmits clock signals and data voltages to ensure data synchronization and signal integrity of the entire display panel, without signal delays or image frame drops.

[0154] This embodiment utilizes collected trace parameters (such as length, width, impedance, etc.) and real-time temperature data to dynamically perceive signal attenuation behavior based on a dynamic equivalent circuit model, thereby improving adaptability and accuracy to environmental changes.

[0155] Through a combined analysis of routing layering and temperature distribution, the display panel is divided into multiple sub-areas (such as a low-temperature core area and a high-temperature edge area), breaking the traditional "one-size-fits-all" regional management model and laying the foundation for subsequent refined driving and power consumption control.

[0156] Directional attenuation compensation is introduced to perform gamma voltage compensation on each pixel. By combining the actual signal attenuation coefficient at that pixel with the temperature coefficient of the area in which it is located, the drive voltage is precisely adjusted to ensure image quality while avoiding overpowering. Raised cosine pulse shaping technology is also used to optimize the output waveform, reduce high-frequency signal spikes, improve signal transmission efficiency, and reduce losses.

[0157] Through linear regression and confidence assessment mechanisms, load impedance is predicted in real time, and adjustment strategies are screened to achieve early intervention and precise matching, improving system energy efficiency and operational stability.

[0158] When the predicted load impedance and confidence level reach a threshold, leakage current assessment is immediately initiated and the system decides whether to enter deep sleep, light sleep, or remain active based on the predicted value. This provides a smarter response and more proactive energy saving compared to traditional sleep modes based solely on "time and user operation."

[0159] When in shallow sleep mode, the non-core area signals are physically disconnected, and the core area maintains a low refresh rate and low drive voltage, reducing power consumption while maintaining some display performance.

[0160] When in deep sleep mode, the core area also stops refreshing and reduces the driving voltage to a safe lower limit, achieving the lowest power consumption state for the entire screen.

[0161] When not in sleep mode, the system maintains standard drive parameters to ensure the display panel's image quality and response speed. Meanwhile, the gamma voltage and pulse parameters optimized in the previous steps remain in effect, prioritizing performance while also taking energy saving into account.

[0162] From front-end signal conditioning and load impedance prediction to back-end sleep management, the entire chain is collaboratively optimized to form a closed-loop energy-saving system. It also integrates AI perception (predicted impedance), big data (historical load), intelligent strategies (dynamic sleep) and circuit regulation to improve the intelligent operation level of the display system. It solves the problems of traditional AM driving such as ignoring routing differences, temperature influence, slow dynamic response, and rough sleep strategy. It significantly reduces the overall energy consumption of the panel, extends the service life of the equipment, and provides a reliable low-power solution for high-resolution and wide-temperature range application scenarios.

[0166] Temperature-attenuation-aware gamma voltage compensation module: For each sub-region, the module uses a temperature and attenuation-aware method to compensate the gamma voltage to obtain an optimized gamma voltage.
