[0002] The control of double-sided display devices usually follows the synchronous refresh algorithm and temperature management strategy of single-sided display products. Although it can provide driving support for the front and rear panels to a certain extent, due to the significant differences in the requirements of each panel for timing accuracy, temperature load and signal coupling in the double-sided display environment, obvious phase mismatch often occurs during high-speed refresh or high-brightness output. Especially when the front panel and the back panel are refreshed synchronously, if there is a lack of timing analysis and load distribution mechanism specifically for the double-sided structure, it is easy to cause difficult-to-capture microscopic interference between the front and back signal channels, causing ghosting, tearing or local delay problems in the double-sided display. Most of the existing technologies only focus on the refresh optimization of a single panel, without comprehensively considering the potential signal interaction and temperature coupling relationship between the front and rear panels in the double-sided structure, and it is difficult to take into account the timing adjustment requirements brought about by high-speed response and thermal effects.

DETAILED DESCRIPTION

Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0018] To facilitate understanding of this embodiment, a control method for a double-sided display device disclosed in an embodiment of the present invention is first described in detail. Figure 1 As shown, the method comprises the following steps: 101. Perform multi-channel timing analysis on the front and rear panels of the double-sided display device to obtain initial delay characteristics and temperature distribution data of the signal lines of the double-sided display device, and evaluate the potential phase mismatch range of different signal channels based on the initial delay characteristics and temperature distribution data to obtain an initial phase offset reference; In one embodiment of the present invention, the multi-channel timing analysis is performed on the front and rear panels of the double-sided display device to obtain the initial delay characteristics and temperature distribution data of the signal lines of the double-sided display device, and the potential phase mismatch range of different signal channels is evaluated based on the initial delay characteristics and temperature distribution data to obtain the initial phase offset reference, including: synchronous sampling processing is performed on the multi-channel driving signals of the front and rear panels of the double-sided display device to obtain a multi-channel initial sampling sequence; according to the multi-channel initial sampling sequence, interval analysis processing is performed on the delay waveforms of each signal line of the double-sided display device in the startup phase to obtain the initial delay characteristics; segmented comparison processing is performed on the distributed thermal sensing data of the front panel and the back panel to obtain temperature distribution data; according to the initial delay characteristics and temperature distribution data, phase mismatch amount inference processing is performed on the coupling areas of different signal channels to obtain the initial phase offset reference.

[0019] Specifically, the multi-channel driving signals of the front and rear panels of the double-sided display device are synchronously sampled and processed to obtain the multi-channel initial sampling sequence. First, a unified trigger pulse is applied to each signal line of the front and rear panels based on the high-speed sampling hardware, and the digitized waveform is continuously acquired at a fixed minimum sampling interval. A multi-level channel selection logic is set in the sampling hardware, and several synchronous sampling values ​​output from the channel multiplexer are recorded in the data buffer by matching the number and priority of the target signal line. If the number of signal lines is large, a parallel grouping strategy can be used to perform polling sampling on signal lines in different areas. In order to meet the high brightness and low power consumption switching requirements in the double-sided display scenario, it is necessary to set a reserved time slot before and after the trigger pulse to overcome the differences in voltage fluctuations and startup delays between the front and back panels. After sampling is completed, the multi-channel signals will be converted into a set of sequences containing timestamps and level information, recorded as ,in Number the signal line. is a discrete sampling moment. The multi-channel initial sampling sequence obtained by this method carries the original timing state of the front and rear panels under the same physical clock. This process relies on distributed trigger control and multi-level cache logic to make the front panel and the back panel at the same reference starting point during the sampling period, and obtain a complete waveform record of each signal line under the condition of minimizing crosstalk. According to the multi-channel initial sampling sequence, the delay waveform of each signal line of the double-sided display device in the startup phase is analyzed and processed, and the process of obtaining the initial delay characteristics can be carried out with the help of an adaptive interval partitioning algorithm. The algorithm first scans the waveform of each signal line before and after the startup moment, and after detecting the stable area of ​​the high level or low level, the corresponding delay interval is calculated according to the actual sampling frequency and the threshold voltage. In order to ensure accuracy, more refined sampling interpolation can be performed on the transition area where the critical level fluctuates up and down, and the interference coefficient can be set to eliminate occasional pulses. Then these data are processed according to the short-time smoothing filtering method to form a set of delay segments with central moments and durations. The delay value can be remembered as ,in is the signal line or channel number. If multiple rising edges or oscillations occur during the startup phase, the threshold judgment and merging strategy can be used to merge adjacent waveform jitters into a unified interval to avoid unnecessary noise interference. Through the above interval analysis and processing, the key delay variation range of all signal lines during the startup phase can be extracted, and these delay characteristics can be stored in a matrix or table, which will be used as a reference for phase mismatch inference later. Such processing can distinguish the differences between the front and rear panels during the power-on process and provide conditions for obtaining more accurate phase evaluation results in combination with temperature data. The distributed thermal sensing data of the front and rear panels are segmented and compared to obtain temperature distribution data. First, multiple thermal sensors are embedded in the double-sided display device. These thermal sensors are distributed near the front and rear panel driver chips and the concentrated area of ​​the heat dissipation channel. The sampled values ​​of these sensors are packaged through consistent timestamps and classified according to dimensions such as panel position, working time and brightness requirements. Then, based on the continuous segmented comparison algorithm, the temperature information recorded in each time period is calculated by difference to form a one-dimensional or two-dimensional temperature gradient sequence. For application scenarios that require higher precision, the segment interval can be further refined into short-period blocks, such as Each sampling period is a block, and the temperature difference between adjacent blocks is accumulated and calculated. The temperature sampling value is recorded as ,in is the sensor number, is the sampling moment. If the temperature sampling values ​​in the same period are stacked into a matrix, local smoothing or least squares fitting can be used to obtain the temperature rise distribution in different areas of the front and rear panels, and the results can be output as temperature distribution data. The segmented comparison process will accurately record the heat increment of each key module, thereby clarifying the correlation information of the temperature difference between the front and rear panels at different channel positions.

[0020] According to the initial delay characteristics and temperature distribution data, the phase mismatch amount is inferred for the coupling area of ​​different signal channels. The process of obtaining the initial phase offset reference relies on a set of multi-dimensional mapping and calculation methods. First, the temperature distribution data generated in the previous step is taken out, and the channel range with high heat accumulation or frequent transition on the front and rear panels is located, and the delay characteristics of these channels are matrix matched with the temperature information. The phase mismatch amount can be expressed as Indicates that is the channel number, is the temperature range or the location of the thermal sensor. If the delay data and temperature data are arranged in vector form, a coupling matrix can be constructed , so that each element satisfies ; in Indicates channel The delay value, After the temperature matrix is ​​mapped to the frequency domain or time domain, the channel and temperature coupling can be extracted through the phase alignment strategy and compared with the established threshold. If some channels exceed the threshold, they can be recorded in the benchmark and the initial phase offset benchmark will be output to distinguish the timing drift degree of the front and rear panels under different thermal conditions. The benchmark contains a more detailed channel-temperature coupling relationship, which will serve as an important reference for subsequent refresh load prediction and synchronization adjustment.

[0021] Furthermore, the phase mismatch amount inference processing is performed on the coupling areas of different signal channels according to the initial delay characteristics and temperature distribution data to obtain an initial phase offset reference, including: performing differentiated induction processing on the initial delay characteristics to obtain a delay classification index, and according to the delay classification index, performing coupling area marking processing on the temperature distribution data to obtain a coupling marking matrix; performing phase offset measurement processing on each signal channel in the coupling marking matrix to obtain a phase mismatch coefficient group; according to the phase mismatch coefficient group, performing benchmark inference processing on the multi-channel driving signal of the double-sided display device to obtain an initial phase offset reference.

[0022] Specifically, the process of performing differentiated induction processing on the initial delay features to obtain the delay classification index is firstly to group the delay samples obtained by multi-channel sampling according to the signal line number or geographical distribution, and perform skewness and kurtosis statistics on the delay data in each group, so that all delay values ​​are recorded in vector form as . Multiple weighted averages are performed to filter out abnormal fluctuations caused by short-term jitter, and different waveform segments are divided into several stable intervals based on the difference threshold. Then, the kernel function mapping or least squares fitting method is used to estimate the delay distribution curve, and the delay values ​​that meet the distribution center are classified according to the difference size, which can be recorded as ,in is the classification index. The delay classification index obtained after the above operation is completed will label the waveforms of the same type and provide comparable classification information for the subsequent coupling area marking stage. According to the delay classification index, the temperature distribution data is processed for coupling area marking. The process of obtaining the coupling marking matrix depends on matching the spatial coordinates and timestamps of the distributed thermal sensor data on the front panel and the back panel. The classified delay index and temperature data are mapped in a one-to-one or one-to-many manner. Each mapping node can be represented by Indicates that Represents the segmented temperature value. After aggregating multiple nodes by region, a matrix record table can be constructed. The matrix elements record the degree of thermal coupling between channels and the similarity of delay types, and indicate the corresponding coupling strength in the form of marks. When a specific classification index is detected to be highly correlated with the temperature segment at the same time, the mark will be given a higher priority value to illustrate that the region has a more sensitive fluctuation range in phase mismatch inference. The coupling mark matrix generated by this marking process will present the coupling relationship between different signal channels and temperature hot spots in a layered manner, laying a correlation basis for the next stage of phase offset measurement. The process of performing phase offset measurement on each signal channel in the coupling mark matrix to obtain a phase mismatch coefficient group requires combining the cumulative delay performance of the front and rear panels in the frequency domain or time domain. Let the coupling mark matrix be denoted as ,in and Corresponding to the delay classification index and temperature range respectively, when When the tag value exceeds the threshold, it means that the channel In the temperature range There is significant coupling in the memory. Using the phase shift formula ; in For Channel The average delay value of Temperature range The corresponding frequency correction factor is, The phase mismatch value can be obtained by using the constant calibration coefficient based on the hardware characteristics in this system. The above operations can be completed in batches under the vectorization framework, and the results are stored in the phase mismatch coefficient group, which is convenient for making a package statistics for multi-channel data. This operation enables each channel with a high coupling mark to obtain the corresponding phase mismatch value in different temperature ranges, and finally forms a set of mismatch coefficients that can be quantitatively compared.

[0023] According to the phase mismatch coefficient group, the multi-channel drive signal of the double-sided display device is subjected to benchmark inference processing, and the process of obtaining the initial phase offset benchmark is performed by comparing the mismatch amount of all channels with the current reference clock or reference timing. If the phase mismatch coefficient is found to be much larger than the general statistical level in a specific channel or temperature range, the channel is marked as a high correction priority in the benchmarking operation. The phase mismatch coefficient group and the reference timing can be combined in matrix form to form a comprehensive table containing channel index, mismatch interval, priority label and offset vector. The table is sorted by channel number, and the optimal phase calibration amount is calculated for each mismatch interval. For example, the calibration value is used Indicates that, based on ; The correction strength is determined by is an adjustable gain factor used to adjust the system tolerance. The above output results constitute the initial phase offset reference, which will be used as a required reference before the multi-channel drive signal is synchronized to avoid ghosting or tearing of the front and rear panels in the phase coupling area.

[0024] 102. According to the initial phase shift reference, the refresh load of the double-sided panel of the double-sided display device is predicted to obtain refresh load prediction data, and based on the refresh load prediction data, the refresh requests of the front and rear panels are differentiated and processed in combination with the temperature evolution to obtain a multi-panel dynamic load distribution parameter; In one embodiment of the present invention, the refresh load of the double-sided panel of the double-sided display device is predicted according to the initial phase offset reference to obtain refresh load prediction data, and based on the refresh load prediction data, the refresh requests of the front and rear panels are differentiated and processed in combination with temperature evolution to obtain multi-panel dynamic load distribution parameters, including: according to the initial phase offset reference, the drive current and refresh frequency of the front and rear panels at different brightness levels are load predicted to obtain refresh load prediction data; the refresh load prediction data is subjected to multi-dimensional evolution mapping processing in combination with the real-time acquisition results of a preset temperature sensor to obtain a temperature evolution curve; according to the temperature evolution curve, the high-brightness refresh request of the front panel and the low-power refresh request of the rear panel are differentiated and processed to obtain the load priority order of different signal channels in a specific temperature range; according to the load priority order, the available timing resources of the front and rear panels are comprehensively allocated to obtain multi-panel dynamic load distribution parameters.

[0025] Specifically, according to the initial phase shift reference, the load prediction processing is performed on the driving current and refresh frequency of the front and rear panels at different brightness levels. The process of obtaining refresh load prediction data can be achieved by setting multiple groups of brightness test conditions at the hardware level and making the front and rear panels perform fast debugging in their respective brightness ranges to collect current peak values ​​and corresponding refresh rates. These collected values ​​are recorded as and in Indicates the brightness level. The data collected under the condition can be used to construct a multidimensional matrix, and the relationship between current and refresh rate can be fitted using the least squares method or interpolation algorithm. The fitting result is combined with the previously obtained phase offset reference to generate the instantaneous load intensity corresponding to each brightness level. In this step, the drive power consumption calculation is regarded as ,in is the operating voltage range of the device. In this way, the refresh loads borne by the front and rear panels respectively can be predicted under different brightness conditions, so that the refresh load prediction data finally outputted can fully reflect the balance between power consumption and refresh rate under the phase alignment requirement. The refresh load prediction data is combined with the real-time acquisition results of the preset temperature sensor and subjected to multi-dimensional evolution mapping processing to obtain the temperature evolution curve. A series of distributed temperature nodes are loaded inside the device. After these nodes are associated with the phase offset reference, the real-time sampled data stream will be compared with the previously measured load prediction data. The multi-dimensional evolution algorithm links the temperature changes in different time periods with the refresh load changes, and generates a temperature-load coupling curve by means of coordinate transformation or Lagrange interpolation. This curve time-series the impact of different refresh intensities on the ambient temperature, and can be used as a function Indicates that is the sampling time step, In the calculation process, the temperature samples are first segmented according to the temperature rise or fall trend, and then matched point by point with the load prediction matrix, and then one or more temperature evolution curves are output to indicate the impact of future temperature rise on refresh requests.

[0026] According to the temperature evolution curve, the high-brightness refresh request of the front panel and the low-power refresh request of the rear panel are distinguished and processed, and the process of obtaining the load priority order of different signal channels in a specific temperature range first needs to extract the temperature critical section from the temperature evolution curve, and map it with the refresh priority index of the front and rear panels at different brightness levels. If it is detected that the temperature rise rate of the front panel in the high-brightness state is far beyond expectations, the refresh time slice of the panel will be temporarily increased or the priority will be placed at a higher level to complete the continuous output of high-brightness display in time. If the temperature amplitude of the rear panel is still in a relatively stable range, the refresh request of the rear panel can be placed at a lower priority. For this type of mapping results, a threshold can be used for judgment. Once the temperature exceeds a preset limit, the channel identification of the corresponding panel is reordered within the temperature range. In this way, when the high and low power panels are driven in parallel, the load priority order can be dynamically updated with temperature changes to ensure that each channel has a timely allocation strategy in the high temperature section or high-speed refresh stage.

[0027] According to the load priority, the available timing resources of the front and rear panels are comprehensively allocated and processed, and the process of obtaining the dynamic load distribution parameters of the multi-panel is based on linear programming or mixed integer programming algorithms, and the refresh windows and available clock cycles of the front and rear panels are regarded as a set of restriction equations, the priority is converted into constraints, and the timing resources of different channels are solved. Let the available timing resource set be Ω\OmegaΩ, and the mapped refresh priorities are arranged in order in the set. If a channel is in high-brightness refresh mode in the high-temperature range, a larger proportion of timing fragments is given in the feasible solution space, and a higher weight coefficient is given in the cost function, so as to obtain a solution vector that can maximize the refresh requirements of both panels at the same time. The solution vector can record the usage rights and refresh rate of each channel in each time slice, and the multi-panel dynamic load distribution parameters finally output can reasonably balance the operating status of the front and rear panels under the temperature and load coupling conditions and maintain synchronous timing.

[0028] 103. Based on the multi-panel dynamic load distribution parameters, the front and rear panels are synchronously refreshed to obtain an initial synchronous refresh result, and according to the initial synchronous refresh result and the temperature accumulation, the refresh sequence and the main clock reference of the rear panel are adjusted to obtain a front-end and rear-end fusion phase correction sequence; In one embodiment of the present invention, based on the multi-panel dynamic load distribution parameters, the front and rear panels are synchronously refreshed to obtain an initial synchronous refresh result, and according to the initial synchronous refresh result and the temperature accumulation, the refresh order and the main clock reference of the back panel are adjusted to obtain a front-end and back-end fusion phase correction sequence, including: according to the multi-panel dynamic load distribution parameters, the channel drive signals of the front panel and the back panel are phase-parallel processed, and based on the phase parallel processing, phase parallel processing is performed to obtain an initial synchronous refresh result; the initial synchronous refresh result is subjected to temperature accumulation evaluation processing to obtain a current temperature rise curve and high-brightness channel load data; according to the current temperature rise curve and the high-brightness channel load data, the refresh order of the back panel is subjected to timing fine-tuning processing, and the main clock reference is subjected to limited phase correction to match the high-speed output range of the front panel; after completing the timing fine-tuning processing and phase correction, a front-end and back-end fusion phase correction sequence that can reflect the synchronization relationship between the front and rear channels is generated.

[0029] Specifically, according to the multi-panel dynamic load distribution parameters, the channel drive signals of the front panel and the back panel are processed in phase parallel, and the process of performing phase parallel processing based on phase parallel processing to obtain the initial synchronous refresh result first requires loading the load distribution parameters in the logic control unit, and uniformly scheduling multiple channels according to the refresh priority and duty cycle limit recorded therein. In order to ensure that each channel achieves phase alignment under the same reference clock, a phase-locked loop (PLL) group can be placed in the hardware circuit to calculate the instantaneous phase drift by monitoring the rising edge moment of each channel, so that the channel At the moment The phase shift is recorded as Once any channel is detected to have a phase out of bounds or mismatch with the reference phase, the phase-locked loop will start the interpolation algorithm and distribute the phase error proportionally to several adjacent refresh cycles, so that the overall phase distribution gradually converges to the given threshold. satisfy ; in It is a channel The weight coefficient is used to reflect the impact of different channels on global phase synchronization. After that, the control unit will synchronize and lock the refresh actions of all channels to a unified phase window by fine-tuning the start and stop moments of the channel drive signals in real time, and record the effective output cycle and data transmission completion time of each channel. The initial synchronous refresh result generated by this process will include the synchronization completion mark of all current channels and a refined phase correction record, which will be used for subsequent cross-comparison with the temperature accumulation status and execution of phase fine-tuning operations. The initial synchronous refresh result is subjected to temperature accumulation evaluation processing, and the process of obtaining the current temperature rise curve and high-brightness channel load data is dynamically called between the temperature acquisition module and the high-brightness monitoring channel of the front panel. First, the temperature acquisition module is used to periodically read the values ​​of several thermal sensors distributed on the surfaces of the front and rear panels and near the drive circuit. And these continuous samples are spliced ​​into a temperature stack in time series, marked with a symbol. Indicates channel At sampling time Next, read the actual power and peak current data of the high-brightness channel in the front panel during this synchronous refresh, and compare this information with the synchronization completion time of the previous phase-locked loop output to obtain the power consumption distribution diagram of the high-brightness output segment. The temperature accumulation curve can be formed by counting the temperature increment and the driving current change of the high-brightness channel in a certain time window. The power at , an approximate model can be established for the temperature evolution function ,in It is the thermal coupling coefficient related to the material properties of the device. After fitting this model to the existing samples, the current temperature rise curve can be generated, and the local heat peak section caused by the high brightness channel load can be located on the curve. This output can reflect the change trend at the temperature level after synchronous refresh, and provide quantitative data support for the subsequent refresh sequence fine-tuning and master clock reference correction.

[0030] According to the current temperature rise curve and the high-brightness channel load data, the refresh sequence of the back panel is fine-tuned, and the main clock reference is phase-corrected to a limited extent to match the high-speed output interval of the front panel. The process requires the use of the channel timing information recorded in the initial synchronization refresh result and the high-brightness load index accumulated in the temperature acquisition module. In order to keep a relatively stable refresh rhythm for the back panel when the front panel is overheated or outputting high brightness, the intersection of the current temperature rise of the front panel and the high-brightness channel power can be extracted before the fine-tuning process, and it can be determined whether the time interval of the point is close to the established refresh time slot of the back panel. If the heat accumulation overlaps with the high-speed load, the refresh sequence is exchanged or delayed in the refresh queue list of the back panel channel to reduce synchronization conflicts with the front panel. At the same time, a phase correction threshold is set for the main clock reference so that within a certain temperature or load boundary, the phase correction only performs a small phase-locked revision to prevent the reference clock of the entire system from fluctuating over a large range. The correction formula can be recorded as ; in is the maximum phase offset of the last calibration, is the weight constant that controls the phase adjustment amplitude, is the reference power value within the safety range. In this way, the front and rear panels can still maintain a reasonable timing gap in the high brightness stage, so that they can still maintain a relatively stable phase relationship when the temperature rises rapidly. After completing the timing fine-tuning processing and phase correction, the process of generating a front-end and back-end fusion phase correction sequence that can reflect the synchronization relationship between the front and rear channels will unify the above-mentioned fine-tuning operations and clock correction records into a correction record table with time stamps and channel labels. This table will include the delay displacement experienced by each channel during the refresh process, the load priority changes involved, and the correction amount of the main clock reference. This information can be encoded as a sequence ,in Indicates time Phase adjustment actions on channels or clock references, with indicators such as temperature, power consumption, and phase drift. All correction items are connected in chronological order to form a front-end and back-end fusion phase correction sequence, which can be used in subsequent refresh cycles or dynamic loading to determine whether small adjustments need to be repeated or restored to a higher refresh rate. Through this global record, different channels can refer to the same set of timing clues in scenarios with high-speed output or sudden heat increase, avoiding large-scale phase misalignment again in the next refresh phase. The sequence can also be called in subsequent monitoring stages to form a closed-loop dynamic control process.

[0031] 104. Utilize the front-end and back-end fusion phase correction sequence to continuously monitor the double-sided display device to obtain a real-time phase offset value, and adjust and control the refresh frequency of the double-sided display device according to the real-time phase offset value and the multi-panel dynamic load distribution parameter.

[0032] In one embodiment of the present invention, the front-end and rear-end fusion phase correction sequence is used to continuously monitor the double-sided display device to obtain a real-time phase offset value, and the refresh frequency of the double-sided display device is adjusted and controlled according to the real-time phase offset value and the multi-panel dynamic load distribution parameter, including: synchronously tracking the front-end and rear-end fusion phase correction sequence within a periodic time window to obtain the current phase acquisition data of each signal channel; based on the phase acquisition data, comparing the actual output of the front and rear panels with the correction sequence to obtain the real-time phase offset value; based on the real-time phase offset value and the multi-panel dynamic load distribution parameter, limiting the refresh frequency of the front panel and the back panel.

[0033] Specifically, the front-end and back-end fusion phase correction sequence is synchronously tracked and processed within a periodic time window to obtain the current phase acquisition data of each signal channel. First, a dynamically configurable synchronous measurement cycle is set in the main clock management unit. The length of the cycle is determined by the upper limit of the refresh frequency of the device and the minimum sampling interval. When entering each measurement cycle, the phase-locked loop (PLL) control circuit reads the key marks in the front-end and back-end fusion phase correction sequence. These marks indicate the reference phase that each channel should follow in the refresh action after the previous round of timing fine-tuning and phase correction. Subsequently, the PLL circuit sends a synchronous trigger signal to the channel drivers of the front and rear panels, and captures the output level waveforms of the channel before and after the trigger point, and converts these waveforms into a set of acquisition data with timestamps through high-speed sampling. Record the channel In cycle The sampling results in ,in Represents a discrete sampling moment. For each channel, the control unit reads the position of the rising and falling edges of the waveform of the channel at the end of the measurement cycle, and calculates the difference with the phase target calibrated in the sequence. If a large deviation occurs, the measurement module will record the deviation in a temporary storage table in an incremental manner for further calculation in the subsequent calibration cycle. After processing all channels, the system interpolates and denoises the collected waveform data, and outputs a set of phase characteristic values. A threshold can be set To determine whether each channel exceeds the reasonable range, if ,in Represents the theoretical reference waveform of the channel under the guidance of the correction sequence, then the channel will be marked as a priority before the next round of synchronous refresh, reminding the subsequent steps to perform fine-tuning of limiting or timing offset. Through this periodic synchronous eye tracking processing, high-precision phase measurement can be completed in a shorter time window, and the phase acquisition data of all current signal channels can be obtained, providing a quantifiable input vector for the subsequent comparison operation link. According to the phase acquisition data, the actual output of the front and rear panels is compared with the correction sequence to obtain the real-time phase offset value. The process is carried out in the calculation module of the central controller. This module first reads the phase acquisition data obtained in the previous stage, and indexes the phase reference value specified for each channel in the front-end and back-end fusion phase correction sequence, and records the channel. The theoretical reference curve is , the measured waveform is In order to implement the comparison process to the executable operator level, the system calculates the phase difference between the two in the frequency domain or time domain. If time domain analysis is used, the cross-correlation function can be used to measure waveform matching, and make Reaching the maximum value After Converted to phase quantity, where is the angular frequency of the refresh signal. If frequency domain analysis is used, the phase components of the measured and reference waveforms can be compared on the frequency components by short-time Fourier transform or discrete Fourier transform, and the difference in the main peak frequency band can be recorded as No matter which method is used, the channel will eventually be generated The real-time phase offset value is stored in the vector After the system completes the phase difference calculation for each channel, it uses the correlation to determine whether there is coupling interference between channels, and classifies the channels with high correlation and simultaneous offset into the same group, so that they can be collaboratively limited or their priorities changed when the refresh frequency is adjusted later. The real-time phase offset value generated by this process can reflect the actual output status between the current front and rear panels and the matching degree of the correction sequence.

[0034] According to the real-time phase offset value and the multi-panel dynamic load distribution parameter, the process of limiting and adjusting the refresh frequency of the front panel and the back panel is executed in the refresh scheduling engine. The refresh scheduling engine first reads the above obtained Vector, and compare the channel priority, brightness expectation and power consumption upper limit in the multi-panel dynamic load distribution parameters to build a solvable limiting strategy matrix. This matrix can be defined as ,in To indicate channel In load distribution scenarios If the measured phase offset Exceeds the specified threshold , then The effective refresh range of the channel is corrected downward to keep the channel at a lower proportion or lower frequency in subsequent synchronous refreshes. In actual operation, the matrix can be adjusted according to the linear programming method. To solve, the objective function can be defined as ,in Representative channel The refresh rate, It is the priority coefficient of this channel in the multi-panel dynamic load distribution parameters. If the critical range is exceeded, constraints are introduced , limit the refresh step that can be increased or decreased in each round of the channel , thus completing the limit adjustment of the refresh frequency. Applying the new refresh frequency configuration obtained in this way to the next round of synchronous refresh can suppress the further expansion of phase drift while maintaining the load balance on both sides. After completing this limit processing, the scheduling engine will archive the new frequency allocation results and update the control parameters of the phase-locked loop, so that the entire system can still perform cyclic dynamic correction based on the real-time monitored data stream in subsequent cycles, ensuring that the phase coordination of the double-sided display device is maintained in a reasonable range.

[0035] In this embodiment, by performing multi-channel timing analysis on the front and rear panels, the initial delay characteristics and temperature distribution data of the signal line are obtained, and the phase mismatch range is evaluated based on this to obtain the initial phase offset reference; then the refresh load of the double-sided panel is predicted based on this reference, and the refresh requests of the front and rear panels are distinguished in combination with the temperature evolution to generate multi-panel dynamic load distribution parameters; based on the parameters, the front and rear panels are synchronously refreshed and the temperature accumulation is evaluated, the refresh order of the back panel and the main clock reference are adjusted, and the front and rear fusion phase correction sequence is generated; finally, the correction sequence is used for continuous monitoring to obtain the real-time phase offset value, and the refresh frequency is adjusted accordingly. This method can significantly reduce the ghosting and synchronization errors of double-sided display under high-speed or high-brightness conditions.
