Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0078] The display effect of the monitor is very important. A good monitor can improve work efficiency. Good display effects can provide more display space, making it easier for users to multitask and place more windows side by side, thereby reducing the time wasted by repeatedly switching pages and improving immersion and work efficiency. Color accuracy: For professional image and video processing work, the color accuracy of the monitor is crucial. The emergence of the high dynamic range (HDR) standard allows monitors to display a wider brightness range and more detailed brightness changes, which is crucial for the user experience of watching high dynamic range content.

[0079] Prior to the technology of the present invention, the existing technology focused more on how to improve the display effect, but ignored how the display process could achieve low-power design and adaptive demand matching design to match the human viewing process, especially the game between display effect and viewer needs, which was difficult to adapt effectively.

[0080] In an embodiment of the present invention, a flexible display control method and system are provided, which realizes flexible control of the display by means of viewing personnel monitoring and weight display.

[0081] According to a first aspect of an embodiment of the present invention, a flexible display control method is provided.

[0082] Figure 1 The present invention is a flowchart of a flexible display control method according to an embodiment of the present invention.

[0083] In one or more embodiments, preferably, the flexible display control method includes:

[0084] S101, setting the current system structure, and starting all sensors under the structure, and storing the sensor information in the online monitoring database;

[0085] S102, judging the type of flexible control to be started according to the content of the online monitoring database at the current moment;

[0086] S103, setting the real-time refresh frequency in the unmanned control mode;

[0087] S104. Retrieving all personnel requirements in manned control mode;

[0088] S105, calculating the comprehensive brightness, comprehensive contrast, comprehensive chromaticity and comprehensive color temperature online according to all the personnel requirements;

[0089] S106, completing flexible control display of the display according to the comprehensive brightness, comprehensive contrast, comprehensive chromaticity and comprehensive color temperature.

[0090] In the embodiment of the present invention, in order to ensure flexible control of the display, the installation equipment and area are first detected, and on this basis, online low power consumption and weighted display matching are performed to adapt to the viewing experience of different people and automatically match.

[0091] Figure 2 The present invention is a flowchart of setting the current system structure in a flexible display control method according to an embodiment of the present invention, starting all sensors under the structure, and storing the sensor information in an online monitoring database.

[0092] like Figure 2 As shown, in one or more embodiments, preferably, the setting of the current system structure, starting all sensors under the structure, and storing the sensor information in the online monitoring database specifically includes:

[0093] S201, setting the structure of the current system to include at least one camera for recording whether there is anyone within the viewing range of the current display;

[0094] S202: After the display is started, the camera is automatically started to shoot and record the numbers of all the people who are watching at the current moment, and the numbers and corresponding times are stored in the database as online monitoring data.

[0095] In an embodiment of the present invention, prepare the environment: ensure that a camera device has been installed in the system, and ensure that the driver of the device has been installed correctly. Set up the camera: configure the parameters of the camera in the system, including resolution, frame rate, etc. Develop a monitoring program: write a program to control the opening and closing of the camera, and to process the video stream captured by the camera. This program should be able to detect whether there is a face in the video stream. If so, generate a unique number and record the number. Connect to the database: connect to the database in the program to store monitoring data. Ensure that the database has been created and there are corresponding tables for storing data. Start the display: when the display starts, automatically start the camera and the monitoring program. The monitoring program should be able to run in the background without affecting the user's use of the display. Record monitoring data: The monitoring program should be able to process the video stream captured by the camera in real time. If a face is detected, the current timestamp and the generated unique number are stored as a record in the database.

[0096] Figure 3 The present invention is a flowchart of a flexible display control method according to an embodiment of the present invention, which determines the type of flexible control to be started according to the content of an online monitoring database at the current moment.

[0097] like Figure 3As shown, in one or more embodiments, preferably, judging the type of flexible control to be started according to the content of the online monitoring database at the current moment specifically includes:

[0098] S301, setting the flexible control type to include manned control and unmanned control;

[0099] S302: When the numbers of all persons included in the online monitoring database content at the current moment are not an empty set, it is under human control; otherwise, it is under unmanned control.

[0100] In an embodiment of the present invention, a control type is defined: two control types are defined in the system, one is manned control and the other is unmanned control. The two control types correspond to whether there is a person in the monitoring database. Create a monitoring database: Create a database in the system to store monitoring data. This database should have a table to record the numbers of all people who are online at each moment. Set the control status: At each moment, check whether the number of the person in the monitoring database is empty. If the number is not empty, the control type is manned control; if the number is empty, the control type is unmanned control. Update the control status: Whenever new monitoring data is generated, the control status should be updated. Specifically, if there is a person's number in the new monitoring data, the control type is set to manned control; if there is no person's number in the new monitoring data, the control type is set to unmanned control.

[0101] Figure 4 The present invention is a flowchart of setting a real-time refresh frequency in an unmanned control mode in a flexible display control method according to an embodiment of the present invention.

[0102] like Figure 4 As shown, in one or more embodiments, preferably, the setting of the real-time refresh frequency in the unmanned control mode specifically includes:

[0103] S401, calculating the real-time refresh frequency using a first calculation formula in real time;

[0104] S402, when it is determined that there is no human control at the current moment, the real-time refresh frequency is sent to the system control center;

[0105] The first calculation formula is:

[0106] HT=(HMAX-HMIN)×(1-T÷Y)+HMIN T<Y

[0107] HT=HMIN T≥Y

[0108] Wherein, HT is the real-time refresh frequency, HMAX is the highest refresh frequency, HMIN is the preset lowest refresh frequency, T is the duration of the unmanned situation, Y is the unmanned situation comparison margin, and the unit is seconds.

[0109] In the embodiment of the present invention, in order to calculate the real-time refresh frequency HT, it is necessary to calculate according to the given first calculation formula and variable values. The formula is as follows: HT = (HMAX - HMIN) × (1 - T ÷ Y) + HMIN when T < Y; HT = HMIN when T ≥ Y; where: HT is the real-time refresh frequency, HMAX is the highest refresh frequency, HMIN is the preset lowest refresh frequency; T is the duration of the unmanned situation; Y is the unmanned situation comparison margin, and the unit is seconds; the specific implementation steps are as follows: Obtain the current variable values: Determine HMAX, that is, the highest refresh frequency allowed by the system. Determine HMIN, that is, the preset lowest refresh frequency of the system. Measure T, that is, the time length from when it is judged to be unmanned control to the current moment. Determine Y, that is, the time margin used to calculate the reduction ratio of the refresh frequency. Apply the first calculation formula: If T < Y, use the formula (HMAX - HMIN) × (1 - T ÷ Y) + HMIN to calculate HT. If T ≥ Y, then HT = HMIN. Real-time monitoring: Continuously monitor the unmanned control state and update the refresh frequency HT in real time according to the first calculation formula. When the system is no longer in the unmanned control state, stop using this formula and adjust the refresh frequency according to the actual situation. Send to the system control center: When it is judged to be unmanned control, send the calculated real-time refresh frequency HT to the system control center. Through the above steps, it can be ensured that the real-time refresh frequency of the system is adjusted according to the predetermined rules in different situations.

[0110] Figure 5 It is a flowchart of retrieving all personnel requirements in the manned control mode in a flexible display control method according to an embodiment of the present invention.

[0111] Such as Figure 5 As shown, in one or more embodiments, preferably, retrieving all personnel requirements in the manned control mode specifically includes:

[0112] S501. Preset the personnel requirements of each person, and the personnel requirements at least include brightness, contrast, chromaticity, and color temperature;

[0113] S502. In the manned control mode, retrieve the preset personnel list and determine whether all the viewing personnel at the current moment are the preset personnel. If so, extract the personnel requirements of the corresponding personnel;

[0114] S503. If they are not the preset personnel, set the current personnel as regular personnel and extract the preset regular personnel requirements, and the regular personnel requirements at least include brightness, contrast, chromaticity, and color temperature.

[0115] In an embodiment of the present invention, personnel requirements are pre-set: First, it is necessary to pre-set their personal display parameter requirements for each person, including brightness, contrast, chromaticity and color temperature. These parameters can be personalized according to factors such as each person's vision condition and preferences. For example, some people may prefer high brightness and high contrast display effects, while some people may need lower brightness and contrast to reduce eye fatigue. In the manned control mode, the system will call up a pre-set list of personnel and determine whether all the viewing personnel at the current moment are pre-set personnel. This step is usually achieved by face recognition or identity authentication. If all the viewing personnel at the current moment are pre-set personnel, the system will extract the personnel requirements of the corresponding personnel and adjust the display parameters of the display device according to these requirements. If there are unpre-set personnel among the viewing personnel at the current moment, the system will set these personnel as regular personnel and extract the pre-set regular personnel requirements. These regular personnel requirements are a set of default display parameters that apply to everyone.

[0116] Figure 6 It is a flow chart of online calculation of comprehensive brightness, comprehensive contrast, comprehensive chromaticity and comprehensive color temperature according to all personnel requirements in a flexible display control method according to an embodiment of the present invention.

[0117] like Figure 6 As shown, in one or more embodiments, preferably, the online calculation of the comprehensive brightness, comprehensive contrast, comprehensive chromaticity and comprehensive color temperature according to the requirements of all personnel specifically includes:

[0118] S601, obtaining the current personnel demand, setting the weight of regular personnel to 0.2, and the weight of personnel in the preset personnel list to the preset weight;

[0119] S602, calculating the comprehensive brightness at the current moment using a second calculation formula;

[0120] S603, calculating the comprehensive contrast at the current moment using a third calculation formula;

[0121] S604, calculating the comprehensive chromaticity at the current moment using the fourth calculation formula;

[0122] S605, calculating the comprehensive color temperature at the current moment using the fifth calculation formula;

[0123] The second calculation formula is:

[0124] LZ=0.8×LMAX+0.2×LAVG

[0125] Among them, LZ is the comprehensive brightness, LMAX is the brightness of the person with the largest weight among all the current viewers, and LAVG is the weighted average brightness of all the current viewers;

[0126] The third calculation formula is:

[0127] DZ=0.8×DMAX+0.2×DAVG

[0128] Where DZ is the comprehensive contrast, DMAX is the contrast of the person with the largest weight among all current viewers, and DAVG is the weighted average of the contrast among all current viewers;

[0129] The fourth calculation formula is:

[0130] ;

[0131] Among them, SZ is the comprehensive chromaticity, si is the chromaticity of the i-th viewer, pi is the weight of the i-th viewer, and n is the total number of all viewers;

[0132] The fifth calculation formula is:

[0133] ;

[0134] Wherein, WZ is the comprehensive color temperature, and Wi is the color temperature of the i-th viewer.

[0135] In an embodiment of the present invention, the current personnel demand is obtained: the weight of the regular personnel is set to 0.2. The weight of the personnel in the preset personnel list is the preset value. Calculate the comprehensive brightness (LZ) at the current moment: use the second calculation formula, LMAX is the brightness of the person with the largest weight among all current viewers, and LAVG is the weighted average of the brightness among all current viewers; calculate the comprehensive contrast (DZ) at the current moment: use the third calculation formula, where DMAX is the contrast of the person with the largest weight among all current viewers, and DAVG is the weighted average of the contrast among all current viewers. Calculate the comprehensive chromaticity (SZ) at the current moment: use the fourth calculation formula, where si is the chromaticity of the i-th viewer, pi is the weight of the i-th viewer, and n is the total number of all viewers. Calculate the comprehensive color temperature (WZ) at the current moment: use the fifth calculation formula, where Wi is the color temperature of the i-th viewer. These calculations will adjust the brightness, contrast, chromaticity and color temperature of the display device based on the personalized needs and weights of each viewer to provide the best visual experience.

[0136] Figure 7The present invention is a flowchart of a flexible display control method according to an embodiment of the present invention, which completes flexible control display of the display according to comprehensive brightness, comprehensive contrast, comprehensive chromaticity and comprehensive color temperature.

[0137] like Figure 7 As shown, in one or more embodiments, preferably, the flexible control display of the display is completed according to the comprehensive brightness, comprehensive contrast, comprehensive chromaticity and comprehensive color temperature, specifically including:

[0138] S701, when the waiting time for a new character change to occur exceeds 2 minutes, extract the comprehensive brightness, comprehensive contrast, comprehensive chromaticity and comprehensive color temperature at the current moment;

[0139] S702: Smoothly adjust the current brightness, contrast, chromaticity and color temperature of the display to the comprehensive brightness, comprehensive contrast, comprehensive chromaticity and comprehensive color temperature within 10 seconds.

[0140] In an embodiment of the present invention, the waiting time is detected: the timing is started when a new character is detected to join. If there is no new character change within 2 minutes, proceed to the next step; if a new character change occurs, the timer is reset. Extract comprehensive parameters: after 2 minutes of no change, calculate and extract the comprehensive brightness (LZ), comprehensive contrast (DZ), comprehensive chromaticity (SZ) and comprehensive color temperature (WZ) at the current moment. Adjust the display parameters: use a smooth transition function to smoothly adjust the brightness, contrast, chromaticity and color temperature of the display from the current value to the calculated comprehensive brightness, comprehensive contrast, comprehensive chromaticity and comprehensive color temperature within 10 seconds. Achieve smooth adjustment: linear interpolation or other smooth transition methods can be used to achieve smooth adjustment of parameters. For example, if it is a linear adjustment, the current parameter can be changed by 10% per second until the target value is reached. The specific mathematical representation and algorithm may be as follows: Assume that the current brightness of the display is Lc, the contrast is Dc, the chromaticity is Sc, and the color temperature is Wc. The comprehensive brightness is LZ, the comprehensive contrast is DZ, the comprehensive chromaticity is SZ, and the comprehensive color temperature is WZ. For each parameter P (which can be brightness, contrast, chromaticity, or color temperature), smooth adjustment can be expressed by the following formula: P(t)=Pc+(Ptarget-Pc)×t÷10 Where: P(t) is the parameter value at time t. Pc is the initial parameter value. Ptarget is the target parameter value (one of LZ, DZ, SZ, WZ). t is the elapsed time in seconds, ranging from 0 to 10. The parameter value is updated once a second until the 10 seconds are up and the parameter value should match the target value.
