[0002] As people's living standards improve, the popularity of cars increases year by year. At the same time, with the advancement of technology, car cockpits are becoming more and more intelligent. As an important carrier of human-computer interaction, the size of the in-vehicle display system is getting larger and larger. Using in-vehicle displays in cars is more harmful to human eyes than using consumer displays. Long-term use is more likely to cause visual fatigue and affect driving safety.

[0003] When designing the display screen, the proportion of blue light in this band is reduced through the display screen optical hardware stacking design, and the color parameters of the display screen are adjusted to the yellowish area. In this way, the visual effect of relieving visual fatigue is achieved. The above solution can reduce the proportion of blue light in the special band of the display screen. The color temperature of the display screen itself will be yellowish. Some users do not like this kind of color tone, sacrificing the configuration options. When designing the in-car entertainment system, based on the use environment of the in-car display screen, the overall color temperature of the UI interface is controlled. When designing the UI, the proportion of blue in the color is reduced to make the color temperature of the entire UI interface yellowish, so as to achieve the visual effect of relieving visual fatigue. This solution requires the design of multiple sets of UI in the host system, which increases the host system's demand for SOC computing power and storage space of storage devices, increases the workload of host development, increases costs, and affects the UI image quality, resulting in limited UI style.

[0029] Embodiment 1

[0030] Figure 1 A flow chart of a display control method for a display device in a vehicle is provided for the first embodiment of the present invention. This embodiment is applicable to the case where a display device in a vehicle is controlled to have a blue light ratio. The method can be executed by a display control device for a display device in a vehicle. The display control device for a display device in a vehicle can be implemented in the form of hardware and / or software. The display control device for a display device in a vehicle can be configured in a vehicle. Figure 1 As shown, the method includes:

[0031] S110 , receiving a control requirement of the display device to be adjusted through a system-level chip, and forwarding the control requirement to a microcontroller chip in the display device to be adjusted.

[0032] In this embodiment, the system-level chip can be understood as a chip in the vehicle for receiving the user's operating instructions for the vehicle. The control demand can be understood as the user's adjustment demand for the display device to be adjusted. The display device to be adjusted can be understood as a display device connected to the vehicle, such as a central control display screen. The microcontroller chip can be understood as a chip for controlling the display device to be adjusted.

[0033] Specifically, the display device to be adjusted can provide the user with a corresponding blue light ratio selection button for adjusting the blue light ratio to achieve the purpose of eye protection. When the user clicks the blue light ratio button, the system-level chip can receive the user's operation on the display device to be adjusted in the vehicle, and generate a corresponding control demand according to the blue light ratio button clicked by the user, and forward the control demand to the microcontroller chip in the display device to be adjusted in the form of a control demand instruction, so that the microcontroller chip responds to the user's control demand.

[0034] S120 , determining the target data group and the associated data group corresponding to the control requirement according to the control requirement and a preset blue light ratio database through the microcontroller chip.

[0035] It is important to know that among the three primary colors used for light mixing in the display, blue light is the most harmful to the human eye, and the brightness of the car display is much greater than that of consumer product displays (such as mobile phones and industrial control monitors). Therefore, the same size has higher blue light energy, and using the car display in the car is more harmful to the human eye than using the consumer display. Long-term use is more likely to cause visual fatigue and affect driving safety. By adjusting the proportion of blue light, the impact of blue light on the human eye can be effectively reduced.

[0036] In this embodiment, the blue light proportion database can be understood as a database storing parameters for adjusting the blue light proportion, wherein the blue light proportion can be understood as the proportion of blue light to white light at different grayscale brightness. The target data group can be understood as a parameter group for adjusting the blue light proportion to the control requirement. The associated data group can be understood as a data group that needs to be adjusted before adjusting to the blue light proportion corresponding to the target data group.

[0037] Specifically, the microcontroller chip can receive the control requirements forwarded by the system-level chip, determine the blue light ratio that the user wants to achieve corresponding to the control requirements, and search in a pre-set blue light ratio database according to the blue light ratio, wherein the blue light ratio database can be pre-stored in the microcontroller chip, and the blue light ratio database can include various blue light ratios and corresponding data groups that can be adjusted to the blue light ratio. Thus, the microcontroller chip can determine the target data group corresponding to the blue light ratio that the user wants to achieve, and determine the associated blue light ratio that is larger than the target blue light ratio in the blue light ratio database, and determine the associated data group corresponding to the associated blue light ratio.

[0038] Exemplarily, the blue light proportion database may include 6 groups of data, namely DefaultGroup, Group1, Group2, Group3, Group4 and Group5. Among them, the blue light proportion corresponding to DefaultGroup is the standard blue light proportion, that is, the blue light proportion when no adjustment is made; Group1 corresponds to the parameters required when the blue light proportion is adjusted to 90% blue light proportion; Group2 corresponds to the parameters required when the blue light proportion is adjusted to 80% blue light proportion; Group3 corresponds to the parameters required when the blue light proportion is adjusted to 70% blue light proportion; Group4 corresponds to the parameters required when the blue light proportion is adjusted to 60% blue light proportion; Group5 corresponds to the parameters required when the blue light proportion is adjusted to 50% blue light proportion. If the target data group corresponding to the control requirement is Group2, the associated data group corresponds to Group1. If the target data group corresponding to the control requirement is Group4, the associated data groups correspond to Group1, Group2 and Group3.

[0039] S130 , controlling the display device to be adjusted according to the associated data group and the target data group.

[0040] It is important to know that according to the spectrum formation principle of the display device, the spectrum ultimately obtained by the display device is the product of the spectra of the LED, backlight and TFT Panel. Under the condition of keeping the LED and backlight spectra unchanged, the proportion of the blue area can be reduced by changing the light transmission spectrum of the TFT Panel. According to the principle of light mixing, white light is a mixture of red, blue and green light. By adjusting the proportion of the three colors when the TFT Panel is working, the transmittance spectrum of the TFT Panel can be adjusted to reduce the transmittance of the blue light source, so as to achieve the purpose of reducing the proportion of blue light after light mixing. In the design of the display device driver IC, corresponding registers are generally designed to configure the proportion of three different lights. The data volume of these internal registers is only about 100Byte, which is relatively small and can be updated.

[0041] Specifically, the associated data group can be first written into the driver IC of the display device to be adjusted through the microcontroller chip, and the display of the display device to be adjusted can be controlled by the driver IC according to the associated data group. Then the target data group is written into the driver IC, and finally the driver IC controls the display of the display device to be adjusted according to the parameters in the target data group, so that the display device to be adjusted can display according to the blue light proportion corresponding to the user's control requirements.

[0042] The technical solution of the embodiment of the present invention receives the control requirements of the display device to be adjusted through the system-level chip, and forwards the control requirements to the microcontroller chip in the display device to be adjusted; through the microcontroller chip, according to the control requirements and the pre-set blue light ratio database, the target data group and the associated data group corresponding to the control requirements are determined; according to the associated data group and the target data group, the display device to be adjusted is controlled. The associated data group corresponding to the target data group is determined by the microcontroller chip in the display device, so as to gradually adjust the blue light ratio of the display device. Without increasing the hardware cost, a variety of blue light ratio options are added for the user, and the blue light ratio in the display device can be gradually adjusted according to the demand, which reduces the damage of the blue light of the display device to the user's eyes, improves the visual comfort, and improves the safety index of the driving process.

[0043] As a first optional embodiment of the first embodiment, based on the above embodiment, the step of determining the blue light proportion database can be further optimized to include:

[0044] The test equipment is used to determine the proportion data of the display device under test at different blue light proportions to form a blue light proportion database.

[0045] In this embodiment, the test equipment can be understood as a device for controlling the conditions required for the test, such as the test equipment can include the host computer software of the computer terminal, the signal source driver board and the optical test equipment, etc. The display device to be tested can be understood as a display device for testing different blue light proportions.

[0046] Specifically, the display parameters of the display device to be tested can be adjusted and tested by the test equipment to obtain the proportion data of the display device to be tested under different blue light proportions, and a blue light proportion database can be formed according to the proportion data.

[0047] Further, based on the above embodiment, the step of determining the proportion data of the display device to be tested under different blue light proportions by using a test device to form a blue light proportion database includes:

[0048] a1. Obtain the calculation parameters of the display device to be tested and the required number of proportions to be set.

[0049] In this embodiment, the calculation parameter can be understood as the parameter required for calculating the blue light proportion. The required number of proportions can be understood as the number of blue light proportions to be set.

[0050] Specifically, the test equipment can be used to obtain the calculation parameters of the display device to be tested, such as the brightness values ​​of red light, green light and blue light at different grayscales, and the voltage value of the display device to be tested. The user can set the required number of blue light proportions in advance according to the minimum blue light proportion to be achieved and the number of blue light proportion adjustment levels, and input them into the test equipment. The test equipment can then obtain the required number of proportions set by the user.

[0051] b1. Determine the intermediate database corresponding to the required number of proportions according to the calculation parameters, the required number of proportions and the pre-set blue light proportion algorithm.

[0052] In this embodiment, the blue light proportion algorithm can be understood as an algorithm for calculating parameter values ​​under different blue light proportions. The intermediate database can be understood as a database storing parameter values ​​under multiple different blue light proportions.

[0053] Specifically, the calculation parameters and the required number of proportions can be input into a pre-set blue light proportion algorithm to obtain proportion data that is the same as the required number of proportions. The proportion data can be used to adjust the proportion of blue light to white light at different grayscale brightnesses, and each proportion data can be stored in an intermediate database.

[0054] Exemplarily, the lowest blue-light proportion in the number of proportion requirements is 55%, and the number of requirements is 9. Then, the China Construction database may include 10 groups of proportion data, namely, the proportion data when the blue-light proportion is the standard proportion, the proportion data when the blue-light proportion is 95%, the proportion data when the blue-light proportion is 90%, the proportion data when the blue-light proportion is 85%, the proportion data when the blue-light proportion is 80%, the proportion data when the blue-light proportion is 75%, the proportion data when the blue-light proportion is 70%, the proportion data when the blue-light proportion is 65%, the proportion data when the blue-light proportion is 60%, and the proportion data when the blue-light proportion is 55%.

[0055] c1. Determine the blue light proportion database based on the intermediate database.

[0056] Specifically, in order to ensure that the proportion data in the intermediate database can enable the display device under test to accurately reach its corresponding blue light proportion, it is necessary to test the accuracy of the proportion data in the intermediate database. The proportion data in the intermediate database can be tested by testing equipment to determine whether the blue light proportion corresponding to the proportion data after the device under test is adjusted according to the proportion data is consistent with that of the proportion data. When the results are consistent, the intermediate database can be determined as the blue light proportion database.

[0057] Further, based on the above embodiment, the step of determining the blue light proportion database according to the intermediate database may include:

[0058] c11. Select any data group in the intermediate database as the data group to be tested.

[0059] In this embodiment, the data group to be tested is a data group for adjusting the display device to be tested.

[0060] Specifically, the intermediate database can be transmitted to the microcontroller chip of the display device to be tested through the test equipment, and any data group in the intermediate database can be randomly selected as the data group to be tested.

[0061] c12. Control the display device to be tested according to the data group to be tested, and determine the optical parameters of the image to be tested in the display device to be tested after the control.

[0062] In this embodiment, the image to be tested can be understood as an image used for comparison display. The optical parameter can be understood as a parameter used to characterize the proportion of blue light in the image to be tested.

[0063] Specifically, the image to be tested can be transmitted to the display device to be tested through the test equipment, and the data group to be tested can be transmitted to the microcontroller chip, so that the microcontroller chip can transmit the data to be tested to the driver IC of the display device to be tested, so that the display device to be tested can display according to the blue light proportion corresponding to the data to be tested, and the optical parameters of the image to be tested after control are obtained through the test equipment.

[0064] c13. When the optical parameters are consistent with the data set to be measured, the intermediate database is used as the blue light proportion database.

[0065] Specifically, the test equipment can be used to determine whether the optical parameters are consistent with the parameters corresponding to the data group to be tested. When the two are consistent, it is considered that the proportion data included in the intermediate database is accurate, and the intermediate database can be used as the blue light proportion database.

[0066] The technical solution of the embodiment of the present invention determines the proportion data group adjusted to the proportion requirement by setting the test equipment according to the set proportion requirement and the collected calculation parameters through the set blue light proportion algorithm, thereby obtaining the intermediate database to be verified, and verifies the randomly selected test data in the intermediate database through the test equipment, and determines whether the test data can accurately meet the proportion requirement according to the optical parameters of the display device to be tested when displayed, and uses the accurate intermediate database as the blue light proportion database. The blue light proportion database can be automatically generated according to different proportion requirements, which increases the scalability of the solution, realizes the automatic generation and verification of the blue light proportion database, and improves the generation efficiency and verification efficiency.

[0067] Embodiment 2

[0068] Figure 2 This is a flow chart of a display control method for a display device in a vehicle provided by Embodiment 2 of the present invention. This embodiment is a further refinement based on the above embodiment. Figure 2As shown, the method includes:

[0069] S210, receiving a control requirement of a display device to be adjusted through a system-level chip, and forwarding the control requirement to a microcontroller chip in the display device to be adjusted.

[0070] S220: Determine the current blue light ratio and the target blue light ratio of the display device to be adjusted according to the control requirement.

[0071] In this embodiment, the current blue light ratio can be understood as the blue light ratio currently displayed by the display device to be adjusted, and the target blue light ratio can be understood as the blue light ratio that needs to be achieved.

[0072] Specifically, when the microcontroller chip receives a control request, the microcontroller chip can first determine the current blue light ratio of the display device to be adjusted, such as by querying the blue light ratio adjusted last time to determine the current blue light ratio. The microcontroller chip can parse the control request and determine the target blue light ratio contained in the control request.

[0073] S230: Determine a target data group and associated data groups according to the current blue light proportion, the target blue light proportion and the blue light proportion database.

[0074] Specifically, the microcontroller chip can search for data groups corresponding to the current blue light ratio and the target blue light ratio in the blue light ratio database, determine the target data group corresponding to the target blue light ratio, and determine the data groups between the current blue light ratio and the target blue light ratio as associated data groups.

[0075] Further, according to the current blue light ratio, the target blue light ratio and the blue light ratio database, the step of determining the target data group and the associated data group may include:

[0076] a2. Determine the target data group based on the target blue light ratio and the blue light ratio database.

[0077] Specifically, the microcontroller chip may search for a data group corresponding to the target blue light ratio in the blue light ratio database, and determine it as the target data group.

[0078] b2. Determine a benchmark data set based on the current blue light ratio and the blue light ratio database.

[0079] In this embodiment, the reference data group can be understood as a data group corresponding to the current blue light ratio.

[0080] Specifically, the microcontroller chip may search for a data group corresponding to the current blue light proportion in the blue light proportion database, and determine it as a reference data group.

[0081] c2. Determine the associated data group based on the benchmark data group, target data group and blue light ratio database.

[0082] Specifically, the data groups included between the reference data group and the target data group may be determined according to the blue light proportion database, and each data group may be determined as an associated data group.

[0083] Exemplarily, the reference data group is Group 3, the target data group is Group 7, and the associated data groups are Group 4, Group 5, and Group 6.

[0084] S240 , reading the arrangement order of the associated data group and the target data group in the blue light proportion database.

[0085] In this embodiment, the arrangement order can be understood as the arrangement order of the proportion of blue light.

[0086] Specifically, each data group in the blue light proportion database can be arranged in descending order according to the blue light proportion, such as Group 1 corresponds to 95% blue light proportion, and Group 2 corresponds to 90% blue light proportion. The microcontroller chip can determine the corresponding arrangement order of the associated data group and the target data group in the blue light proportion database.

[0087] For example, the associated data groups are Group 3 and Group 4, and the target data group is Group 5, then the corresponding arrangement order is Group 3 first, then Group 4, and finally Group 5.

[0088] S250: Control the display device to be adjusted according to the associated data group, the target data group and the arrangement order.

[0089] It should be noted that since the new parameters corresponding to the target data group take effect in a short time, multiple sets of parameters can be switched within 1s (under standard display conditions, 60 frames will be displayed in 1 second). The reference data group and the target data group can be displayed in an average of 60 frames, which has less visual impact on the human eye.

[0090] Specifically, the microcontroller chip can write the associated data group and the target data group into the driver IC of the display device to be adjusted in sequence according to the arrangement order, so that the display device to be adjusted can display with the target blue light proportion corresponding to the control demand.

[0091] For example, the reference data group is Group2, the target data group is Group6, and the associated data groups are Group3, Group4 and Group5. The corresponding arrangement order is 1, Group3, 2, Group4, 3, Group5, 4, Group6. The associated data groups and the target data groups can be written into the driver IC of the display device to be adjusted in order from 1 to 4.

[0092] The technical solution of the embodiment of the present invention forwards the user's control demand to the microcontroller chip of the display device to be adjusted through the system-level chip, so that the target blue light ratio corresponding to the control demand and the current blue light ratio of the display device to be adjusted are determined through the microcontroller chip of the display device to be adjusted, and the target blue light ratio and the target data group and the reference data group corresponding to the current blue light ratio are determined according to the blue light ratio database, and then the associated data group is determined, and the associated data group and the target data group are transmitted to the driver IC of the display device in sequence, and the blue light ratio of the display device to be adjusted is adjusted through the driver IC, and gradually adjusted to the target blue light ratio corresponding to the target data group. Without increasing the hardware cost, a variety of blue light ratio options are added for users, and the blue light ratio in the display device can be gradually adjusted according to the demand, which reduces the damage of the blue light of the display device to the user's eyes, improves the visual comfort, and improves the safety index of the driving process.
