[0026] It should be noted that the display optimization method of the vehicle-mounted LCD screen provided in the embodiment of the present application is generally executed by the terminal device, and accordingly, the display optimization device of the vehicle-mounted LCD screen is generally set in the terminal device.

[0027] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is merely illustrative. Any number of terminal devices, networks and servers may be provided as required.

[0028] Continue to refer Figure 2 , shows a flow chart of an embodiment of a method for optimizing the display of a vehicle-mounted liquid crystal display screen according to the present application. The method for optimizing the display of a vehicle-mounted liquid crystal display screen comprises the following steps: Step S201, obtaining current environmental parameters corresponding to the liquid crystal display screen installed in the vehicle.

[0029] In this embodiment, the display optimization method of the vehicle-mounted liquid crystal display screen is run on the electronic device (eg Figure 1 The terminal device shown in the figure can send or receive data via a wired connection or a wireless connection. It should be noted that the above-mentioned wireless connection methods may include but are not limited to 3G / 4G / 5G connections, WiFi connections, Bluetooth connections, WiMAX connections, Zigbee connections, UWB (ultra wideband) connections, and other wireless connection methods currently known or to be developed in the future.

[0030] Among them, the current environmental parameters corresponding to the on-board LCD display include but are not limited to current temperature parameters, current humidity parameters, and current air pressure parameters. The vehicle equipped with the LCD display collects environmental data in real time through sensors, and then the on-board central processing unit (CPU) pre-processes the environmental data to obtain the current environmental parameters.

[0031] In one embodiment, a vehicle equipped with an LCD display is installed with a temperature sensor, a humidity sensor, and an air pressure sensor, which can collect temperature data, humidity data, and air pressure data of the vehicle's current environment in real time as the original environmental data of the current environment. By preprocessing the original environmental data, such as filtering and normalization, the current environmental parameters corresponding to the LCD display installed in the vehicle can be obtained.

[0032] Step S202 : predicting a target motion state of the liquid crystal molecules in the liquid crystal display screen under the current environmental parameters according to a preset liquid crystal molecule motion model.

[0033] The liquid crystal molecule motion model is a pre-set mathematical model, and the target motion state is the actual motion state of the liquid crystal molecules in the liquid crystal display screen under the current environmental parameters, which can be predicted by the liquid crystal molecule motion model.

[0034] In one embodiment, a finite element analysis method is used to simulate the motion of liquid crystal molecules under different environmental parameters, thereby establishing a relationship model between environmental parameters and the motion patterns of liquid crystal molecules. This model, based on the physical principles of liquid crystal display, establishes the relationship between environmental parameters and the motion of liquid crystal molecules. For example, the current environmental parameters include the current temperature parameter, the current humidity parameter, and the current air pressure parameter. From the temperature dimension, the model contains a functional relationship between the temperature parameter and the average kinetic energy of the liquid crystal molecules. Substituting the current temperature parameter into the function, the average kinetic energy of the liquid crystal molecules at the current temperature can be calculated. Similarly, based on the correlation function between the humidity parameter and the alignment state of the liquid crystal molecules, and the correlation function between the air pressure parameter and the intermolecular forces of the liquid crystal molecules, the relevant physical quantities corresponding to the current environmental parameters are calculated. Through these calculations, the basic physical data of the motion of the liquid crystal molecules under the current environmental parameters are obtained. These data represent the actual motion state of the liquid crystal molecules and serve as the target motion state of the liquid crystal molecules.

[0035] Step S203 , obtaining target motion parameters corresponding to the target motion state, and determining an offset between the standard motion parameters of the liquid crystal molecules under a standard environment and the target motion parameters.

[0036] Among them, the target motion parameters include the average kinetic energy, arrangement state and intermolecular force of the liquid crystal molecules under the current environmental parameters, and the standard motion parameters include the standard average kinetic energy, standard arrangement state and standard intermolecular force of the liquid crystal molecules under the standard environment.

[0037] Optionally, the standard environment is regarded as an ideal environment for the movement of liquid crystal molecules, that is, under the standard environment, the liquid crystal display is regarded as being able to achieve the best display effect. For example, the standard environmental parameters corresponding to the standard environment include: temperature of 25°C, humidity of 50%, and air pressure of standard atmospheric pressure.

[0038] In one embodiment, the liquid crystal molecule motion model includes target motion parameters corresponding to the target motion state of the liquid crystal molecules under current environmental parameters, including target average kinetic energy, target alignment state, and target intermolecular forces. Furthermore, the liquid crystal molecule motion model includes standard motion parameters for the liquid crystal molecules under a standard environment, including standard average kinetic energy, standard alignment state, and standard intermolecular forces. Therefore, by calculating the difference between the standard average kinetic energy and the target average kinetic energy, the difference between the standard alignment state and the target alignment state, and the difference between the standard intermolecular forces and the target intermolecular forces, the offset between the standard motion parameters and the target motion parameters can be determined.

[0039] Step S204 : generating adjustment parameters corresponding to the liquid crystal display screen according to the offset and preset compensation parameters.

[0040] The offset includes an average kinetic energy offset, an arrangement state offset, and an intermolecular force offset. The adjustment parameters include, but are not limited to, a driving voltage adjustment parameter, a backlight brightness adjustment parameter, and a color gamut mapping adjustment parameter.

[0041] In one embodiment, pre-set compensation parameters are determined based on compensation rules pre-set in the vehicle's central processing unit (CPU). By correcting the average kinetic energy offset based on the compensation parameters, a drive voltage adjustment parameter for adjusting the liquid crystal display can be generated. By correcting the alignment state offset based on the compensation parameters, a backlight brightness adjustment parameter for adjusting the liquid crystal display can be generated. By correcting the intermolecular force offset based on the compensation parameters, a color gamut mapping adjustment parameter for adjusting the liquid crystal display can be generated.

[0042] Step S205 , adjusting the liquid crystal display screen according to the adjustment parameters to obtain a liquid crystal display screen after display optimization.

[0043] In one embodiment, the adjustment parameters include at least a driving voltage adjustment parameter, a backlight brightness adjustment parameter, and a color gamut mapping adjustment parameter. The driving voltage adjustment parameter is transmitted to the driving circuit of the liquid crystal display screen, so as to adjust the driving voltage waveform and compensate for the response delay of the liquid crystal molecules; the backlight brightness adjustment parameter is transmitted to the backlight control system of the liquid crystal display screen, so as to dynamically adjust the backlight brightness; and the color gamut mapping adjustment parameter is transmitted to the display control system of the liquid crystal display screen, so as to optimize the color display and avoid color deviation.

[0044] This application effectively improves the environmental adaptability of the vehicle-mounted LCD display by monitoring the current environmental parameters corresponding to the vehicle-mounted LCD display in real time and dynamically compensating its display performance based on the current environmental parameters, thereby preventing the display performance from degrading in abnormal environments.

[0045] In some optional implementations of this embodiment, the offset includes an average kinetic energy offset, an arrangement state offset, and an intermolecular force offset. The step of generating an adjustment parameter corresponding to the liquid crystal display screen based on the offset and a preset compensation parameter includes: The average kinetic energy offset, the arrangement state offset, and the intermolecular force offset are corrected according to the compensation parameter to generate the adjustment parameter.

[0046] In one embodiment, the compensation parameters are determined by a preset compensation rule. The compensation parameters are used to correct the average kinetic energy offset, the alignment state offset, and the intermolecular force offset to generate adjustment parameters. The adjustment parameters include, but are not limited to, a drive voltage adjustment parameter, a backlight brightness adjustment parameter, and a color gamut mapping adjustment parameter. The drive voltage adjustment parameter corresponds to compensation for response delay, the backlight brightness adjustment parameter corresponds to compensation for contrast reduction, and the color gamut mapping adjustment parameter corresponds to compensation for color deviation.

[0047] Optionally, the generated adjustment parameters may also include refresh rate adjustment parameters, viewing angle adjustment parameters, anti-aging adjustment parameters and power consumption balancing adjustment parameters, wherein the refresh rate adjustment parameters correspond to compensation for screen ghosting, the viewing angle adjustment parameters correspond to compensation for screen reflection, the anti-aging adjustment parameters correspond to compensation for pixel attenuation, and the power consumption balancing adjustment parameters correspond to compensation for high-load operation.

[0048] This application compensates for the difference between the motion state of liquid crystal molecules under standard environmental parameters and the motion state under current environmental parameters according to preset compensation parameters, thereby ensuring the normal display of the vehicle-mounted LCD screen in abnormal environments and effectively improving the environmental adaptability of the vehicle-mounted LCD screen.

[0049] In some optional implementations of this embodiment, the step of correcting the average kinetic energy offset, the arrangement state offset, and the intermolecular force offset according to the compensation parameters to generate the adjustment parameters includes: Correcting the average kinetic energy offset according to the compensation parameter to generate a first parameter for adjusting a response delay corresponding to the liquid crystal display screen; Correcting the arrangement state offset according to the compensation parameter to generate a second parameter for adjusting the background brightness corresponding to the liquid crystal display screen; Correcting the intermolecular force offset according to the compensation parameter to generate a third parameter for adjusting the color display corresponding to the liquid crystal display screen; The first parameter, the second parameter and the third parameter are used as the adjustment parameters.

[0050] Among them, the first parameter is the driving voltage adjustment parameter, which is used to adjust the driving voltage waveform of the LCD screen to avoid response delay; the second parameter is the backlight brightness adjustment parameter, which is used to adjust the backlight brightness of the LCD screen to avoid the background brightness being too high or too low; the third parameter is the color gamut mapping adjustment parameter, which is used to adjust the color display of the LCD screen to avoid color shift.

[0051] In some optional implementations of this embodiment, the step of obtaining the target motion parameter corresponding to the target motion state and determining the offset between the standard motion parameter of the liquid crystal molecules under a standard environment and the target motion parameter includes: Extracting the target motion parameters through the liquid crystal molecule motion model; Determining a numerical deviation and a proportional deviation between the standard motion parameter and the target motion parameter; The offset is determined according to the numerical deviation and the proportional deviation.

[0052] The preset liquid crystal molecular motion model contains functional relationships between multiple environmental parameters and the liquid crystal molecular motion state parameters under these environmental parameters. Numerical deviation refers to the absolute difference between the target motion parameters corresponding to the liquid crystal molecules under the current environmental parameters and the standard motion parameters corresponding to the liquid crystal molecules under the standard environmental parameters. Proportional deviation refers to the relative rate of change between the target motion parameters corresponding to the liquid crystal molecules under the current environmental parameters and the standard motion parameters corresponding to the liquid crystal molecules under the standard environmental parameters.

[0053] In one embodiment, the target motion parameters of the liquid crystal molecules in the liquid crystal display screen installed in the vehicle under the current environmental parameters can be extracted through the liquid crystal molecular motion model, so as to determine the numerical deviation and proportional deviation between the standard motion parameters and the target motion parameters, and finally determine the offset between the standard motion parameters and the target motion parameters based on the numerical deviation and proportional deviation.

[0054] In some optional implementations of this embodiment, after the step of adjusting the liquid crystal display screen according to the adjustment parameters to obtain a liquid crystal display screen with optimized display, the method further includes: Displaying a test image through the display-optimized liquid crystal display screen, and determining a response speed index, a contrast index, and a color deviation index of the test image; determining whether the liquid crystal display screen reaches an ideal display state according to the response speed index, the contrast index, and the color deviation index; If the liquid crystal display screen does not reach an ideal display state, the adjustment parameter is updated according to the response speed index, the contrast index, and the color deviation index.

[0055] The ideal display state is the display state of the liquid crystal display screen under a standard environment.

[0056] In one embodiment, after optimizing the LCD display based on display parameters, it is still necessary to monitor the display quality of the LCD. Test images are evaluated using an image quality assessment algorithm to quantitatively evaluate indicators such as response speed, contrast, and color deviation. These indicators are then evaluated to determine whether the ideal display state has been achieved. If it is detected that the display quality still does not meet the ideal state, the adjustment parameters are updated based on the response speed index, contrast index, and color deviation index. Subsequently, the LCD display can be optimized again using the updated adjustment parameters, forming a closed-loop feedback loop. This application evaluates the image quality of the vehicle-mounted LCD screen after display optimization, and updates the adjustment parameters based on the evaluation results. The updated adjustment parameters can then be used to optimize the LCD screen again, achieving closed-loop feedback and improving the intelligence of the display optimization of the vehicle-mounted LCD screen.

[0057] In some optional implementations of this embodiment, before the step of predicting the target motion state of the liquid crystal molecules in the liquid crystal display screen under the current environmental parameters based on the preset liquid crystal molecule motion model, the method further includes: Determining the average kinetic energy, arrangement state, and intermolecular forces of the liquid crystal molecules under the multiple preset environmental parameters by simulating the movement of liquid crystal molecules in the liquid crystal display screen under the multiple environmental parameters, wherein the multiple environmental parameters include temperature parameters, humidity parameters, and air pressure parameters; The liquid crystal molecule motion model is constructed according to the mapping relationship between the temperature parameter and the average kinetic energy, the mapping relationship between the humidity parameter and the arrangement state, and the mapping relationship between the air pressure parameter and the intermolecular force.

[0058] In one embodiment, finite element analysis can be used to simulate the motion of liquid crystal molecules in a liquid crystal display under multiple environmental parameters to obtain the motion patterns of the liquid crystal molecules, thereby determining the average kinetic energy, alignment state, and intermolecular forces of the liquid crystal molecules under the multiple environmental parameters, where each environmental parameter includes a temperature parameter, a humidity parameter, and an air pressure parameter. Therefore, in the liquid crystal molecule motion model, under the multiple environmental parameters, the mapping relationship between the temperature parameter and the average kinetic energy is a functional relationship between the temperature parameter and the average kinetic energy, the mapping relationship between the humidity parameter and the alignment state is a functional relationship between the humidity parameter and the alignment state, and the mapping relationship between the air pressure parameter and the intermolecular forces is a functional relationship between the air pressure parameter and the intermolecular forces.

[0059] This application improves the accuracy of subsequent dynamic compensation of the display performance of the liquid crystal display screen by pre-building a liquid crystal molecular motion model.

[0060] In some optional implementations of this embodiment, the step of obtaining current environmental parameters corresponding to the liquid crystal display screen mounted in the vehicle includes: Collecting raw environmental data corresponding to the vehicle, and filtering the raw environmental data to obtain filtered raw environmental data; The filtered original environmental data is normalized to obtain the current environmental parameters.

[0061] In one embodiment, after the vehicle's central processing unit (CPU) receives the raw environmental data transmitted by the sensor, it can filter the data to remove noise interference and further normalize the data, thereby converting the data from different types of sensors into a unified numerical range for subsequent analysis.

[0062] This application uses software algorithms to achieve display optimization of vehicle-mounted LCD screens. Compared with traditional hardware modification solutions, there is no need for large-scale replacement of LCD screen hardware, which reduces production and maintenance costs.

[0063] The embodiments of the present application can acquire and process relevant data based on artificial intelligence technology. Artificial intelligence (AI) refers to the theories, methods, techniques, and application systems that use digital computers or machines controlled by digital computers to simulate, extend, and expand human intelligence, perceive the environment, acquire knowledge, and use that knowledge to achieve optimal results.
