Technical Field

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

[0002] With the rapid development of information technology and the popularization of new display technologies, the power consumption problem of display devices has become a key bottleneck restricting the sustainable development of the industry. Glass-based display panels driven by AM 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 mostly ignore dynamic changes and only rely on static design redundancy, resulting in energy consumption waste. And traditional methods adopt a globally unified driving strategy, without dividing the core / non-core areas according to the trace length, temperature distribution, and functional requirements of the display panel. Therefore, only a rough and unified sleep strategy is adopted in power consumption management, and regionalized, hierarchical, and intelligent low-power regulation cannot be achieved. In view of this, the present invention proposes a low-power signal transmission method for a glass-based display panel based on AM driving to solve the above problems. Summary of the Invention

[0009] Further, 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, then start the leakage current evaluation in advance to calculate the predicted leakage current value. The specific method for triggering the sleep state according to the predicted leakage current value includes: When the predicted load impedance reaches the upper limit of the load impedance and the confidence level exceeds the standard confidence level, start the leakage current evaluation in advance to calculate the predicted leakage current value; if the predicted leakage current value is less than A1, perform a shallow sleep, if the predicted leakage current value is greater than A2, perform a deep sleep, and if the predicted leakage current value is between A1 and A2, do not perform a sleep; 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, continue to monitor; When entering the shallow sleep state, the row - column drive clock signal and data line in the non - core area are physically disconnected from the drive voltage to stop energy consumption; the core area reduces power consumption by dynamically reducing the standard refresh rate and standard drive voltage. When entering the deep sleep state, the row and column drive clock signals and data lines in the non-core area are physically disconnected from the drive voltage; the refresh rate in the core area drops to zero, the drive voltage is reduced to the lowest safe value, the glass-based display panel stops refreshing, enters the lowest power consumption state, and basically only maintains necessary data storage and status preservation; When not entering the sleep state, the core area and the non-core area operate normally. The core area has a standard refresh rate and a standard drive voltage to ensure smooth display of the display panel and high response speed of signal transmission. The non-core area continues to receive and process the row and column drive clock signals to ensure normal transmission of display data, and is in a high power consumption state to meet the update and response requirements of the real-time display panel without any power consumption optimization.

[0010] Furthermore, when entering the shallow sleep state, the row and column drive clock signals and data lines in the non-core area are physically disconnected from the drive voltage, and the energy consumption is stopped; the specific ways for the core area to reduce power consumption by dynamically reducing the standard refresh rate and the standard drive voltage include: 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 the core area; 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 the non-core area; In the non-core area, the clock signals of the row drive and column drive in the non-core area are disconnected through a gating switch (such as a MOSFET); and a low-leakage MOS switch is used to physically disconnect the data lines in the non-core area from the drive voltage, and a pull-up resistor is applied to the disconnected data lines to prevent repeated charging and discharging caused by level drift; In the core area, the standard drive voltage in the core area is dynamically reduced through the standard refresh rate, and the reduced power consumption is obtained based on the reduced refresh rate and drive voltage for low-power transmission; among them, the timing signal is parsed through the display interface protocol to directly read the refresh rate.

[0011] Furthermore, when entering the deep sleep state, the row and column drive clock signals and data lines in the non-core area are physically disconnected from the drive voltage; the refresh rate in the core area drops to zero, the drive voltage is reduced to the lowest safe value, the glass-based display panel stops refreshing, and the specific ways to enter the lowest power consumption state include: When entering the deep sleep, for the non-core area, the clock signals of the row drive and column drive are disconnected, and the data lines in the non-core area are disconnected from the drive voltage; 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.

[0012] Further, the specific ways for the core area and the non-core area to operate normally when not entering the sleep state include: When not entering the sleep state, the core area and the non-core area perform continuous refreshing, operate normally, and do not perform power consumption optimization processing; The core area continues to operate with the standard refreshing frequency and standard driving voltage to ensure the response speed and display clarity of image processing and signal transmission.

[0013] The non-core area maintains the operation of the clock signals of the row drive and the column drive. At the same time, the data line continues to be connected to the driving voltage to perform normal transmission and display of the image data in the display panel.

[0014] Technical effects and advantages of the low-power signal transmission method for the glass-based display panel based on AM driving of the present invention: The present invention utilizes the collected trace parameters (such as length, width, impedance, etc.) and real-time temperature data. Based on the dynamic equivalent circuit model, it can dynamically sense the signal attenuation behavior, improving the adaptability and accuracy to environmental changes; Through the composite analysis of trace layering + temperature distribution, the display panel is divided into multiple sub-regions (such as a low-temperature core area, a high-temperature edge area, etc.), breaking the traditional "one-size-fits-all" regional management mode, laying a foundation for subsequent refined driving and power consumption control; The direction attenuation compensation method is introduced to perform gamma voltage compensation on each pixel point. Combining the actual signal attenuation coefficient of this point with the temperature coefficient of the region where it is located, the driving voltage is accurately adjusted to ensure the image quality while avoiding over-power supply; and the raised cosine pulse shaping technology is used to optimize the output waveform, reduce high-frequency signal spikes, improve the signal transmission efficiency, and reduce losses; Through the linear regression and confidence evaluation mechanism, the load impedance is predicted in real time, and the adjustment strategy is screened to achieve early intervention + fine matching, improving the system energy efficiency and operation stability; When the predicted load impedance and confidence reach the threshold, the leakage current evaluation is immediately started and the system decides to enter the deep sleep, shallow sleep or keep active state according to the predicted value. Compared with the traditional sleep mode based only on "time + user operation", the response is more intelligent and the energy saving is more proactive; When in the shallow sleep state, the signals in the non-core area are physically disconnected, and the core area maintains a low refresh rate and a low driving voltage, reducing the power consumption while maintaining partial display performance; When in the deep sleep state, the core area also stops refreshing and reduces the driving voltage to the safety lower limit, achieving the lowest power consumption state of the entire screen; In the non-sleep state, the system maintains the operation with standard driving parameters to ensure the image quality and response speed of the display panel. At the same time, the gamma voltage and pulse parameters optimized by the previous steps are still effective, taking into account the energy saving performance while giving priority to performance; From the front-end signal conditioning, load impedance prediction to the back-end sleep management, the whole-link collaborative optimization is formed to create a closed-loop energy-saving system; and by integrating AI perception (impedance prediction), big data (historical load), intelligent strategies (dynamic sleep) and circuit regulation, the intelligent level of the display system operation is improved; the problems of ignoring wiring differences, temperature effects, slow dynamic response, and rough sleep strategies in traditional AM driving are solved; the overall power consumption of the panel is significantly reduced, the service life of the device is extended, and a reliable low-power solution is provided for high-resolution and wide-temperature application scenarios.

[0017] Embodiment 1

[0018] Please refer to Figure 1 As shown, the low-power signal transmission method for the glass-based display panel based on AM driving in this embodiment includes: Step SS1: By collecting the wiring parameters and ambient temperature data of the glass substrate, based on the equivalent circuit mechanism, calculate the signal attenuation coefficient; generate a wiring hierarchical area map according to the wiring length; generate a composite division map based on the upper and lower limit temperature gradients on the wiring hierarchical area map, and the composite division map includes N sub-regions; Step SS2: Temperature-attenuation perception gamma voltage compensation: For each sub-region, use the temperature and attenuation perception method to compensate the gamma voltage to obtain the optimized gamma voltage; among them, the temperature and attenuation perception method is based on the temperature coefficient and the actual signal attenuation coefficient, and compensates the original gamma voltage through the direction attenuation compensation method to generate the compensated gamma voltage; use the raised cosine pulse shaping technology to output the optimized gamma voltage; Step SS3.

Step SS4. Adaptive sleep strategy trigger: 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, then start the leakage current evaluation in advance to calculate the predicted leakage current value, and trigger the sleep state according to the predicted leakage current value; if the predicted leakage current value is less than A1, enter the light sleep state; if the predicted leakage current value is greater than A2, enter the deep sleep state; if the leakage current value is between A1 and A2, then enter the non-sleep state.

[0019] The specific method for calculating the signal attenuation coefficient by collecting the trace parameters and ambient temperature data of the glass substrate based on the equivalent circuit mechanism includes: The trace parameters of the glass substrate include trace length, trace width, pitch, and material impedance; among them, the trace length, trace width, and pitch are automatically extracted as the optimal trace length, trace width, and pitch during the circuit design stage of the glass-based display panel when using EDA software for layout design by parsing the GDSII and Gerber file formats. The material impedance is obtained in real time by using an impedance analyzer. Obtain the current ambient temperature data through a temperature sensor. According to the trace parameters of the glass substrate and the current ambient temperature data (trace length, trace width, pitch, material impedance), query the pre-stored trace database 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. The pre-stored trace database covers the equivalent circuit characteristics under different trace lengths, widths, pitches, material impedances, and temperature conditions, including resistance, inductance, capacitance, and conductance parameters. Each record in the database corresponds to a trace configuration and its electrical response under specific environmental conditions. The dynamic equivalent parameters of any trace structure under the current temperature environment can be quickly obtained through the index matching method, supporting real-time modeling of signal transmission and energy consumption analysis. For example: The collected trace parameters of the glass substrate are: trace length is 1, trace width is 2, pitch is 3, and material impedance is 4; retrieve the equivalent circuit model parameters corresponding to the trace length of 1, trace width of 2, pitch of 3, and material impedance of 4 in the pre-stored trace database. Retrieve the resistance in the equivalent circuit model parameters corresponding to the routing parameters of the current glass-based display panel. Based on the resistance in the equivalent circuit model parameters, calculate the difference between the current ambient temperature data and the reference temperature data to calculate the resistance at the current ambient temperature data. The formula is: , where is the length resistance, is the temperature coefficient, is the reference ambient temperature data (25 °C), is the length resistance at the current ambient temperature data; Calculate the signal attenuation coefficient based on the resistance in the corresponding equivalent circuit model parameters and the resistance at the current ambient temperature data. The reason why 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 is that resistance is one of the key parameters affecting the attenuation degree of signals in the transmission line; in the equivalent circuit model, the resistance of the routing changes with temperature (usually increases with the increase of temperature), thus directly affecting the energy loss during signal transmission; by comparing the equivalent resistance at the reference temperature with the corrected resistance at the current temperature, the change degree of signal transmission loss can be reflected. The equivalent circuit model is a common method in the prior art and is widely used in circuit design and signal transmission analysis; in this model, each element of the physical circuit (such as resistance, inductance, capacitance, and conductance) is regarded as an idealized electrical component to simplify the analysis of the actual circuit; for the routing of the glass substrate, the equivalent circuit model can accurately describe the electrical characteristics of the signal during transmission in the routing by converting the geometric structure (such as length, width, spacing) and material properties (such as impedance) of the routing 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 and provide a basis for optimizing signal quality and reducing power consumption.

[0020] Traditional methods usually adopt a globally unified design redundancy, and all regions rely on the same transmission strategy, which ignores the actual differences in different regions (such as the core area and the edge area); regardless of the distance and temperature of signal transmission, the same strategy is adopted, which often leads to excessive power consumption in some regions while other regions are in a waste state. Generate a routing layer area map according to the routing length; on the basis of the routing layer area map, generate a composite division map according to the upper and lower limit temperature gradients. The specific way that the composite division map includes N sub-regions is as follows: 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. 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); 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. 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. 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; 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. 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. 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.

[0021] For each sub-region, the gamma voltage is compensated using temperature and attenuation sensing. The optimized gamma voltage is obtained by: The temperature values corresponding to the pixel points in each sub-region are weighted to obtain the temperature coefficient of the sub-region; Based on the signal attenuation coefficient and the trace length of each pixel point, calculate the actual signal attenuation coefficient of each pixel point; For the original gamma voltage corresponding to each pixel point, use the direction attenuation compensation method to compensate the original gamma voltage of each pixel point to obtain the compensated gamma voltage. The formula is: , where is the original gamma voltage signal of the pixel point , is the compensated gamma voltage of the pixel point , is the temperature coefficient of the sub-region corresponding to the pixel point , is the actual signal attenuation coefficient; Among them, the direction attenuation compensation method calculates the compensated gamma voltage based on the temperature coefficient and the actual signal attenuation coefficient for the original gamma voltage of each pixel point; this method introduces a temperature coefficient, which represents the temperature influence of the sub-region where each pixel point is located, and the temperature coefficients of each sub-region are different. Combining the actual signal attenuation coefficient, that is, the cumulative effect of signal attenuation suffered by this point, to adjust the original gamma voltage to obtain the compensated gamma voltage; Based on the compensated gamma voltage, output the optimized gamma voltage through the raised cosine pulse shaping technology; The raised cosine pulse shaping technology is a signal optimization technology widely used in digital communication. It reduces inter-symbol interference (ISI) and optimizes spectrum usage by designing a pulse signal with a limited bandwidth; this technology uses a pulse with a raised cosine function shape in the frequency domain, adjusts the roll-off factor of the signal, and smooths the signal waveform, thereby reducing interference and distortion during transmission and enhancing the anti-noise ability of the signal; in the display panel technology, applying the raised cosine pulse shaping technology can effectively optimize the gamma voltage output, ensure the accuracy of signal transmission and image quality, and reduce display problems caused by signal interference or noise; Each sub-region introduces an independent temperature coefficient to reflect its current actual thermal state; combining the pixel-level trace length and the signal attenuation coefficient to achieve "tailored" voltage compensation for each pixel; instead of a one-size-fits-all global approach, it performs hierarchical compensation according to the physical property differences of different regions of the display panel, significantly improving the accuracy.

[0022] According to the optimized gamma voltage, calculate the current load impedance based on Ohm's law; classify it into low level, medium level, and high level in combination with historical load impedance data, and construct an impedance-pulse parameter mapping table; predict the load impedance through linear regression and pre-adjust the pulse parameters; and the specific ways to calculate the confidence level according to the residual and its standard deviation between the predicted and actual load impedances include: Based on the optimized gamma voltage and current, calculate the current load impedance according to Ohm's law; Classify according to historical load impedance; classify into low level, medium level and high level; the low level is , the medium level is , the high level is , where is the load impedance, and are the upper and lower limits of the standard load impedance, set by the empirical method; Construct an impedance-pulse parameter mapping table; Use the historical load impedance as the input and obtain the predicted load impedance by the linear regression method; According to the current load impedance, obtain the corresponding adjustment pulse parameters from the impedance-pulse parameter mapping table, that is, the duty cycle and frequency of adjustment; Use the predicted load impedance to pre-adjust the adjustment pulse parameters to obtain the pre-adjusted pulse parameters; the formula is: , where and are the pre-adjusted pulse parameters, is the predicted load impedance, and are the frequency of adjustment and the duty cycle of adjustment, queried and obtained from the impedance-pulse parameter mapping table; Calculate the residual based on the difference between the predicted load impedance and the actual load impedance; and calculate the standard deviation of the residual, and calculate the confidence level based on the residual and the standard deviation of the residual, the formula is: , where represents the residual, represents the standard deviation of the residual, is the confidence level; Perform forward-looking fine-tuning on the pre-adjusted pulse parameters through the predicted impedance; actually predict the future load impedance and its corresponding adjustment pulse parameters; Through the predicted load impedance + pre-adjusted pulse parameters, the adaptive optimization of the pulse parameters (such as frequency, duty cycle) is realized in advance, thus significantly improving the matching and energy efficiency of the drive signal; different from the traditional method that only relies on fixed pulse settings or empirical redundant designs, this scheme first dynamically calculates the current load impedance using the optimized gamma voltage and current, combines historical data for classification 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.

[0023] The specific ways to construct the impedance-pulse parameter mapping table include: Taking the load impedance, the load impedance change rate, the optimized gamma voltage, and the current as inputs, and using genetic algorithm optimization to obtain the optimal solution for each load impedance, where the optimal solution is the pulse parameter; For the level corresponding to the load impedance, adjust the optimal solution. If the load impedance is at a low level, use the ambient temperature data to compensate the optimal solution to obtain the compensated optimal solution, which is the adjusted optimal solution in the low level; the formula is: , where is the optimal solution in the low level, is the adjusted optimal solution in the low level, is the ambient temperature data, 0.002 is the temperature compensation coefficient, and 25 is the reference ambient temperature data; If the load impedance is at a medium level, use the working time of the glass-based display panel to compensate the optimal solution to obtain the compensated optimal solution, which is the adjusted optimal solution in the medium level; the formula is: , where is the optimal solution in the medium level, is the adjusted optimal solution in the medium level, is the working time of the glass-based display panel, 0.05 is the aging compensation factor, and 1000 is the reference time; If the load impedance is at a high level, use the ambient temperature data and the driving voltage to calculate the adjusted driving voltage, and use the adjusted driving voltage to compensate the optimal solution to obtain the compensated optimal solution, which is the adjusted optimal solution in the high level; the formula for the adjusted driving voltage is: , where is the driving voltage, is the adjusted driving voltage, 0.01 is the driving voltage derating coefficient, and 60 is the critical ambient temperature data; the formula for the adjusted optimal solution in the high level is: ; the adjusted optimal solution is the adjusted pulse parameter; For the load impedance and its corresponding adjusted pulse parameter, construct an impedance-pulse vector; Construct an impedance-pulse parameter mapping table from M impedance-pulse vectors; If the load impedance is not found in the impedance-pulse parameter mapping table, use linear interpolation to calculate the adjusted optimal solution corresponding to the load impedance; It can achieve refined and customized adjustment of pulse parameters under different load impedance states. By introducing a genetic algorithm for global optimization, it ensures that the pulse parameters have global optimal performance. 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 a linear interpolation mechanism, it ensures that effective pulse parameters can be obtained quickly and continuously under any load state, improving the overall response speed, accuracy, and energy efficiency control ability of the system.

[0024] Traditional methods usually adopt a globally unified sleep strategy or a static threshold trigger mechanism, ignoring the differences in wiring structure, heat distribution, and functional importance among different regions within the panel. This coarse-grained management method is prone to two types of problems: one is mis-triggering (i.e., entering the sleep state under non-critical conditions, affecting the display performance); the other is hysteretic triggering (i.e., being unable to respond to high-power states in a timely manner, resulting in continuous increase in energy consumption). At the same time, traditional methods lack a judgment mechanism based on prediction and confidence, and the regulation lacks flexibility and forward-lookingness, and cannot dynamically adapt to actual working condition changes, showing obvious lag and inefficiency in modern high-resolution and high-refresh-rate display panels. 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, then the leakage current evaluation is started in advance to calculate the predicted leakage current value. The specific ways to trigger the sleep state according to the predicted leakage current value include: When the predicted load impedance reaches the upper limit of the load impedance and the confidence level exceeds the standard confidence level, start the leakage current evaluation in advance and calculate the predicted leakage current value. The formula is: , where k is a constant, is the temperature adjustment coefficient, is the aging influence coefficient; is the predicted leakage current value. If the predicted leakage current value is less than A1, then enter the shallow sleep state. If the predicted leakage current value is greater than A2, then enter the deep sleep state. If the predicted leakage current value is between A1 and A2, then do not enter the sleep state. Among them, the upper limit of the load impedance and the standard confidence level are obtained by the expert method; When entering the shallow sleep state, the row and column drive clock signals and data lines in the non-core area are physically disconnected from the drive voltage to stop energy consumption. The core area reduces power consumption by dynamically reducing the standard refresh rate and standard drive voltage; When entering the deep sleep state, the row and column drive clock signals and data lines in the non-core area are physically disconnected from the drive voltage; the refresh rate of the core area drops to zero, the drive voltage is reduced to the lowest safe value, and the glass-based display panel stops refreshing and enters the lowest power consumption state, basically only maintaining necessary data storage and status preservation; When not entering the sleep state, the core area and the non-core area operate normally. The core area has a standard refresh rate and a standard driving voltage to ensure smooth display of the display panel and high response speed of signal transmission. The non-core area continues to receive and process row and column driving clock signals to ensure normal transmission of display data. It is in a high-power state to meet the update and response requirements of the real-time display panel without any power consumption optimization. An adaptive sleep control mechanism based on load impedance prediction and confidence evaluation is implemented, which is highly intelligent and targeted. By setting reasonable upper and lower limits of load impedance and confidence thresholds, areas truly in abnormal or overloaded states can be effectively identified, leakage current can be evaluated and predicted in advance, and then selectively enter the shallow or deep sleep state, greatly improving the accuracy and real-time performance of energy consumption management. In addition, the sleep state distinguishes between the core area and the non-core area, which not only ensures the continuous operation of the key functions of the panel but also avoids resource waste in unnecessary areas, realizing the collaborative optimization of local sleep + dynamic power consumption reduction.

[0025] When entering the shallow sleep state, the row and column driving clock signals, data lines, and driving voltage in the non-core area are physically disconnected to stop energy consumption. The specific ways for the core area to reduce power consumption by dynamically reducing the standard refresh rate and standard driving voltage include: 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 the core area, and 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 the non-core area. In the non-core area, the clock signals of the row drive and column drive in the non-core area are disconnected through a gating switch (such as a MOSFET), and a low-leakage MOS switch is used to physically disconnect the data lines in the non-core area from the driving voltage, and a pull-up resistor is applied to the disconnected data lines to prevent repeated charge and discharge caused by level drift. In the core area, the standard driving voltage of the core area is dynamically reduced through the standard refresh rate. Based on the reduced refresh rate and driving voltage, the reduced power consumption is obtained for low-power transmission. Among them, the refresh rate is directly read by parsing the timing signal through the display interface protocol. For example: when entering the shallow sleep state, the standard refresh rate needs to be reduced from 120 Hz to 30 Hz. When the standard refresh rate is 120 Hz, the standard driving voltage is 15 V. Then when the refresh rate is reduced to 30 Hz, the driving voltage is obtained by multiplying the ratio of 30 Hz to 120 Hz by the standard driving voltage of 15 V, which is 10.6 V. The power consumption at this time is calculated by the capacitance, the square of the reduced driving voltage of 10.6 V, and the refresh rate of 30 Hz, where the capacitance is obtained through a capacitance sensor. The clock signals for row driving and column driving are key signals used for synchronously controlling the refreshing of pixel rows and columns in a glass-based display panel; Row driving clock signal: Controls the scanning timing of one row of pixels through the horizontal synchronization signal (HSYNC) to ensure that each row of pixels is refreshed row by row in sequence; Column driving clock signal: Coordinates data transmission in the column direction through the synchronization clock (CLK) to ensure that pixel columns receive correct data during the refreshing of each row; In the shallow sleep state, these clock signals are disconnected through a gating switch (such as a MOSFET), causing the row and column driving circuits in the non-core area to stop working, thereby cutting off the power consumption; The data line connects the driving 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 for the corresponding area; By dividing the display panel into a core area and a non-core area, differential management can be implemented according to the importance and working status of different areas, avoiding image delay or response lag caused by global unified sleep; Use a gating MOSFET to disconnect the row and column driving clocks in the non-core area and the connection between the data line and the driving voltage, and cooperate with a pull-up resistor to prevent level drift, achieving a true "physical isolation" and completely cutting off the source of invalid power consumption; The core area is not directly powered off, but the refresh rate and driving voltage are dynamically reduced by analyzing the timing signal, achieving the minimum power consumption output while maintaining the basic display performance, ensuring smooth display and user experience.

[0026] When entering the deep sleep state, the row and column driving clock signals and the connection between the data line and the driving voltage in the non-core area are physically disconnected; The specific methods for the refresh rate in the core area to drop to zero, the driving voltage to drop to the lowest safe value, and the glass-based display panel to stop refreshing and enter the lowest power consumption state include: When entering deep sleep, for the non-core area, disconnect the clock signals of row driving and column driving and disconnect the data line and the driving voltage in the non-core area; For the core area, reduce the refresh rate to 0 and reduce the driving voltage to the lower limit of the safe driving voltage, so that the display panel no longer refreshes and enters the lowest power consumption state; By reducing the refresh rate in the core area to 0, reducing the driving voltage to the safe lower limit, and completely disconnecting the driving and data circuits in the non-core area, the entire panel enters a static state, only maintaining necessary data retention and status preservation, and the power consumption almost drops to the theoretical minimum; Adopt physical-level disconnection (such as a MOS switch to disconnect signals and voltages), completely cut off all energy consumption channels in the non-working area, and avoid any form of leakage or standby power consumption; Although the driving voltage is reduced to the minimum, it still remains above the "lower limit of safe driving voltage" to ensure that circuit components are not damaged. At the same time, by maintaining the necessary data state, it prevents entering the deadlock or re-initialization state; it is especially suitable for situations such as long-term standby, no signal input, and night use, achieving the state of "automatic freeze + extreme energy saving", extending the device life and reducing heat accumulation.

[0027] When not entering the sleep state, the specific ways for the core area and non-core area to operate normally include: When not entering the sleep state, the core area and non-core area perform continuous refreshing, operate normally, and do not perform power consumption optimization processing; The core area continues to operate at the standard refresh frequency and standard driving voltage to ensure the response speed and display clarity of image processing and signal transmission.

[0028] The non-core area maintains the operation of the clock signals of the row drive and column drive. At the same time, the data line continues to be connected to the driving voltage to perform normal transmission and display of image data in the display panel; The core area operates at the standard refresh frequency and standard driving voltage, which can maintain accurate color reproduction, uniform brightness, and no image smear, ensuring a high-quality visual experience; 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 delay or image frame loss.

[0029] This embodiment utilizes the collected trace parameters (such as length, width, impedance, etc.) and real-time temperature data. Based on the dynamic equivalent circuit model, it can dynamically sense the signal attenuation behavior, improving the adaptability and accuracy to environmental changes; Through the composite analysis of trace layering + temperature distribution, the display panel is divided into multiple sub-regions (such as low-temperature core area, high-temperature edge area, etc.), breaking the traditional "one-size-fits-all" regional management mode, laying a foundation for subsequent refined driving and power consumption control; The direction attenuation compensation method is introduced to perform gamma voltage compensation on each pixel point. Combining the actual signal attenuation coefficient of this point with the temperature coefficient of its location area, the driving voltage is precisely adjusted to ensure image quality while avoiding over-power supply; and the raised cosine pulse shaping technology is used to optimize the output waveform, reduce high-frequency signal spikes, improve signal transmission efficiency, and reduce losses; Through the linear regression and confidence evaluation mechanism, the load impedance is predicted in real time, and the adjustment strategy is screened to achieve early intervention + fine matching, improving the system energy efficiency and operation stability; When the predicted load impedance and confidence level reach the threshold, the leakage current assessment is immediately initiated, and based on the predicted value, it is decided whether to enter deep sleep, shallow sleep, or remain active. Compared with the traditional sleep mode based only on "time + user operation", the response is more intelligent and the energy saving is more proactive; When in shallow sleep, the signals in the non-core area are physically disconnected, and the core area maintains a low refresh rate and low driving voltage, reducing power consumption while maintaining partial display performance; When in deep sleep, the core area also stops refreshing and reduces the driving voltage to the safety lower limit, achieving the lowest power consumption state for the entire screen; In the non-sleep state, the system operates with standard driving parameters to ensure the image quality and response speed of the display panel. At the same time, the gamma voltage and pulse parameters optimized in the previous steps are still effective, taking into account energy saving performance while giving priority to performance; From front-end signal regulation, load impedance prediction to back-end sleep management, the entire link is collaboratively optimized to form a closed-loop energy-saving system; and it integrates AI perception (predicted impedance), big data (historical load), intelligent strategies (dynamic sleep), and circuit regulation to improve the intelligent level of the display system operation; it solves problems such as ignoring wiring differences, temperature effects, slow dynamic response, and rough sleep strategies in traditional AM driving; significantly reduces the overall power consumption of the panel, extends the service life of the device, and provides a reliable low-power solution for high-resolution and wide-temperature application scenarios.
