Description

LED displays (Light Emitting Diode Display Screen) are a modern display technology widely used for displaying images, text and video. They use Light Emitting Diodes (LEDs) as light sources, which can produce bright, high contrast images. LED displays have a wide variety of applications including televisions, computer displays, outdoor billboards, large screens in stadiums, digital billboards in shops, traffic signals, and many other fields.
The resolution of an LED display screen is typically determined by the arrangement of its physical pixels, and thus adjustment of the resolution is typically required based on the hardware characteristics of the display screen itself. The resolution represents the number of pixels on the screen, typically in terms of horizontal and vertical pixel numbers (e.g., 1920x1080, representing 1920 pixels horizontally and 1080 pixels vertically).
Resolution adjustment of LED displays is typically done to accommodate different application requirements and signal sources. By adjusting the resolution, the user can ensure that the best image quality and visual effect are obtained in different situations. For example, adjusting resolution under different display content and video sources may provide clearer images, better compatibility, and ensure that the display screen is capable of presenting the best appearance of the content. Therefore, the LED display screen can be flexibly configured according to different occasions and requirements so as to meet specific requirements of users.
The existing LED display screen has some problems in resolution adjustment, and the existing method is generally insufficient for fully analyzing the operation conditions of software and hardware under different resolutions. Although display effects at some resolutions may be good, it is easy to cause excessive utilization of system display resources or display loads to continue to run high, and these hidden problems are not easily found in the conventional art.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Fig. 1 shows a method for adjusting resolution of an LED display screen according to the present invention, including the steps of:
step S100, acquiring resource parameters when the resolution of a display screen is regulated, acquiring software graphic resource requirements under the current resolution according to the resource parameters, and collecting the software graphic resource requirements under different resolutions to construct a data set;

and step S400, analyzing the soft-hard coordination difference index to generate a perfect signal and a readjusting signal.
The software and hardware resource requirements under different resolutions are greatly changed, including processor performance, display memory of a display card, bandwidth and the like, and if effective resource management and control are not available, resource waste or shortage can be caused, so that the system performance is affected. And secondly, the control capability of the software and hardware resources is related to the quality of the display effect. Reasonable resource allocation can ensure that clear and smooth images can be obtained under different resolutions without causing blurring, jamming or rendering problems. Furthermore, resource management also involves energy conservation and thermal management. More power and heat sink resources may be needed at high resolution, so effective resource management helps to reduce energy consumption, reduce heat generation, and extend hardware life. In summary, analyzing and recording software and hardware resource management capabilities is critical when the display adjusts to different resolutions. This helps optimize resource allocation, improves display effects, and ensures that the system operates efficiently and stably under a variety of conditions. Such analysis and recording is a critical step in ensuring display performance and reliability.
The step S100 specifically includes the following steps:
the resource parameters comprise a total video memory, a used video memory, graphic resource requirements of task processes and reserved graphic resources;
the graphic resource requirements of the general existing and used video memory and task processes and the reserved graphic resources are comprehensively calculated to obtain the software graphic resource requirements, wherein the calculation formula is as follows:
in the formula, M, TGM, UGM, GRD, RGR is respectively software graphics resource requirement, total video memory, used video memory, graphics resource requirement of task process and reserved graphics resource.
The software graphics resource requirements are used to evaluate the usability of the display for software and hardware resource management at the current resolution, especially in situations where graphics resources are limited.
The total video memory refers to all the available graphic memory capacity on the display card or the graphic adapter, and is the sum of the capacity of graphic resources such as graphic data, text textures and the like stored in the display card;
existing memory capacity is used to refer to memory capacity that has been allocated and used in the current computing or graphics task;
the graphic resource requirement of a task process refers to the graphic resource required by the running task or process and is used for measuring the requirement of one task or process on the graphic performance;
reserved graphics resources are one type of graphics resources that are provided to ensure system stability and performance. Typically, an operating system or application program reserves a portion of resources in the available memory to cope with sudden graphics demands or to ensure that the system is functioning properly. These resources are typically not used by tasks or processes, but can be used to provide additional performance or standby resources when needed.
The step S200 specifically includes the following:
the software graphic resource requirement data adjusted to each resolution is recorded, and the data structure data sets are counted.
Sequentially sequencing the data in the data set from small to large according to the resolution ratio, and calculating a resource management coefficient, wherein the calculation formula is as follows:
wherein RMC is a resource management coefficient, X o Represents the o-th data in the data set,the average value of the logarithmic data is represented, o represents the data number, o=1, 2, … …, N is a positive integer, and N represents the total number of data.
The larger the value of the resource management coefficient, the worse the software and hardware resource management capability of the display screen under different resolutions, namely, insufficient resource allocation and management, resulting in performance degradation, image quality degradation or other problems. This means that at high resolution or different resolutions, the software and hardware of the display screen cannot effectively adapt or allocate the required resources, resulting in an insufficient resource situation; on the contrary, if the value of the resource management coefficient is lower, the software and hardware resource management capability of the display screen is better under different resolutions, and the resource can be effectively adapted and allocated so as to meet the requirements under different resolutions. Meaning that the display screen can accommodate different resolutions without degrading performance or image quality, providing a better user experience.
Comparing the resource management coefficient with the first display quality threshold and the second display quality threshold respectively, if the resource management coefficient is smaller than the first display quality threshold, indicating that the resource allocation and management regulation and control capability adjusted to each resolution is good, and generating an advanced management signal, wherein the display quality is stable and good under different resolutions;
when the resource management coefficient is larger than or equal to the display quality threshold, the resource allocation and management regulation and control capability adjusted to each resolution is poor, and a readjustment signal is generated;
if the resource management coefficient is greater than or equal to the first display quality threshold and less than the second display quality threshold, the resource allocation and management regulation and control capability under different resolutions are generally indicated, the improvement and lifting space is larger, and further analysis is needed to generate a medium-level management signal.
When the resolution of the display is adjusted, the invention collects a plurality of software graphic resource demand data, constructs a data set, and comprehensively analyzes the data set to calculate resource management coefficients. This factor helps analyze the resource management conditions during resolution adjustment to find potential operational problems. In addition, the resource management coefficient is compared with the first display quality threshold and the second display quality threshold respectively, and management signals of different levels are generated according to the comparison result. The method is beneficial to real-time monitoring and evaluation of the resource use condition under different resolutions, the resource use degree grade is clear, and support is provided for better feedback adjustment effect.
The software and hardware resource requirements at different resolutions are greatly different, and the coordination of the software and the hardware can ensure that the resources are effectively allocated and managed. If the software and hardware are not coordinated, resource waste, performance degradation and even system breakdown can be caused. Second, software and hardware coordination is critical to the user experience. Resolution adjustment may affect image quality, response time, and fluency. By coordinating software and hardware, better display effect can be provided, the problems of blurring, blocking, delay and the like are avoided, and the user satisfaction is improved. In addition, software and hardware coordination may also help discover potential problems and bottlenecks. By recording the coordination information, the shortage, conflict or deficiency of resources can be timely identified, so that the optimization and improvement can be carried out in a targeted manner, and the stable operation of the system under various resolutions can be ensured. In summary, the coordination of analysis and recording software and hardware is important when the display adjusts different resolutions, which is helpful to optimize resource management and improve user experience, and ensures that the system can operate efficiently and stably under various conditions. Such analysis and recording is a critical step in ensuring display performance and reliability.
The step S300 specifically includes the following:
step S311, under the condition of obtaining the advanced and intermediate management signals, recording coordination information when the display adjusts the resolution, where the coordination information includes a display frame rate, a resolution adjustment frequency, a data volume displayed by each frame, a software graphics demand resource rendered by each frame, a response time of the display screen, and a refresh period of the display, and calculating a soft and hard coordination index of the display by the coordination information, where a calculation formula is as follows:
wherein:
p is a software and hardware coordination index;
N f for displaying the frame rate;
r is resolution adjustment frequency;
F s the amount of data displayed for each frame;
M f software graphics rendered for each frame require resources;
c is CPU performance factor;
t is the response time of the display screen;
d is the refresh period of the display;
the soft and hard coordination index is used for measuring the running pressure of the software and hardware at different resolutions in unit time, reflects the coordination ability of the software and hardware, and aims to measure whether the performance of the display can effectively meet the required graphics processing and rendering requirements under specific resolution and display setting so as to ensure that a user obtains good visual experience.
Step S312, collecting data of a plurality of soft and hard coordination indexes in the running period of the display, sequencing the soft and hard coordination indexes from large to small, selecting the maximum value, the middle value and the minimum value of the soft and hard coordination indexes as initial clustering centers, and creating three corresponding initial clusters;
step S313, for each soft and hard coordination index, calculating the distance between the soft and hard coordination index and each cluster center, and distributing the soft and hard coordination index to the cluster closest to the cluster center;
step S314, calculating the average value of all data points in each cluster, and taking the average value as a new cluster center;
step S315, repeatedly executing step S313 and step S314 until the clustering center is not changed, and distributing each software and hardware coordination index into the cluster of the final clustering center to form a final clustering result;
step S316, obtaining a soft-hard coordination difference index, wherein the calculation formula is as follows:
wherein:
e is a soft-hard coordination difference index;
k is the number of clusters;
i is the index of the cluster;
L i the number of data points for cluster i;
P ij the software and hardware coordination index value of the jth data point in the cluster i;
μ i the mean value of the software and hardware coordination indexes of the cluster i;
the soft and hard coordination difference index is used for analyzing the overall soft and hard coordination capability trend when the resolution of the display is adjusted, and if the soft and hard coordination difference index is smaller, the soft and hard coordination overall effect is better, and the effect trend is more consistent.
Step S317, comparing the soft-hard coordination difference index with a coordination consistency threshold, if the soft-hard coordination difference index is smaller than the coordination consistency index, indicating that the display resolution adjustment effect is better, and generating a perfect signal; if the soft-hard coordination difference index is greater than or equal to the coordination consistency index, the fact that the soft-hard coordination difference index is greater than or equal to the coordination consistency index indicates that the soft-hard coordination is inconsistent or different exists between the soft-hard coordination, which means that after resolution adjustment, the cooperative work between the soft-hard coordination is limited or has some problems, so that the display effect is poor, the performance is reduced or other problems are caused, and a readjustment signal is generated.
Under the condition of acquiring high-level and medium-level management signals, the invention records the coordination information of the display when the resolution is adjusted, and comprehensively analyzes the information to calculate the soft-hard coordination difference index. And simultaneously, recording the performance data of the display switched to different resolutions, and carrying out summary analysis. By adopting macroscopic integral modes such as cluster analysis and the like to evaluate the adjustment result, the data analysis in multiple directions such as the coordination of software and hardware under different resolutions, the resource management and control and the coordination performance and the like is considered, and the effect is explicitly adjusted based on objective factors.
