[0032] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0033] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0034] An embodiment of the present application provides an embodiment of a method for processing information of a display screen. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0035] FIG1 is a flow chart of a method for processing information on a display screen according to an embodiment of the present application. As shown in FIG1 , the method may include the following steps:

[0036] Step S102: acquiring display information when the target image is displayed on the display screen.

[0037] In the technical solution provided in step S102 of the present application, the display information may include: color information of the display screen, grayscale information of the display screen, content displayed by the image on the display screen, image data of the display screen, brightness and chromaticity information of the display screen, and uniformity information of the display screen. The uniformity information may be used to indicate the uniformity of the target image displayed on the display screen. For example, the brightness and chromaticity information may include brightness information and / or chromaticity (or color temperature) information of the display screen. The uniformity information may be used to indicate whether the brightness and chromaticity information of different display areas of the display screen are consistent when displaying the target image. Evaluation indicators of the uniformity information may include: pixel light intensity uniformity, display module brightness uniformity, and module brightness uniformity. The image data may include three primary colors (Red, Green, and Blue, abbreviated as RGB) image data (or RGB data signals). This is merely an example and is not specifically limited.

[0038] In this embodiment, display information when a target image is displayed on a display screen is obtained. For example, the brightness information and / or chromaticity information of the target image displayed on the display screen can be measured by a brightness tool. For example, the brightness tool can be used to measure the brightness and chromaticity information in the target image. The brightness tool can be a photoelectric sensor, a colorimeter, etc. This is only used as an example and is not specifically limited. By performing pixel-level operations on the target image displayed on the display screen, the color information of each pixel in the target image can be obtained. By performing grayscale operations on the target image displayed on the display screen, a grayscale image corresponding to the target image can be obtained. Then, the grayscale image can be processed by methods such as a grayscale histogram to obtain grayscale information. In addition, by detecting different areas in the display screen using a uniformity testing device, uniformity information can be obtained.

[0039] Step S104: obtaining temperature information when the display screen displays information.

[0040] In the technical solution provided in the above-mentioned step S104 of the present application, the above-mentioned brightness and chromaticity information and the above-mentioned uniformity information can change with the change of the temperature information of the display screen. The above-mentioned temperature information can be used to indicate the temperature of the display screen under a certain power consumption. For example, the above-mentioned brightness information and / or the above-mentioned chromaticity information, as well as the uniformity of the target image displayed by the above-mentioned display screen, can change with the change of the temperature information of the display screen.

[0041] In this embodiment, after obtaining the display information when the target image is displayed on the display screen, the temperature information when the display screen displays the display information is obtained. For example, based on the display information when the target image is displayed on the display screen, the power consumption of the display screen under the current display can be calculated, and then based on the power consumption and temperature prediction model, the temperature information when the display screen displays the display information can be calculated, that is, the temperature of the display screen under the current power consumption can be calculated.

[0042] Optionally, the above power consumption can be used to represent the power consumption of different display areas in the display screen at the current moment. Based on the power consumption and temperature prediction model, the temperature information of the display screen when displaying the display information can be calculated. For example, by inputting the power consumption into the temperature prediction model for prediction processing, the temperature of the display screen under the current power consumption can be obtained.

[0043] Step S106 , obtaining brightness and chromaticity compensation coefficients and uniformity compensation coefficients corresponding to the temperature information.

[0044] In the technical solution provided in the above step S106 of the present application, the above brightness and chromaticity compensation coefficient can be determined based on the correlation between the brightness and chromaticity information and the temperature information of the display screen, and the above uniformity compensation coefficient can be determined based on the pixel value in the target image. For example, the above brightness and chromaticity compensation coefficient can also be called the brightness and color temperature compensation coefficient, and the above uniformity compensation coefficient can also be called the thermal uniformity compensation coefficient.

[0045] In this embodiment, the correlation between the brightness and chromaticity information and the temperature information may be such that a change in the temperature information is linearly related to a change in the brightness and chromaticity. For example, for every 1°C increase in the temperature information of the display screen, the relative change in the RGB tristimulus values ​​in the pixel is also different. The pixel value may be the main component of RGB captured by the camera in a cold screen state, and the pixel value may also be the main component of RGB captured by the camera in a hot screen state.

[0046] Optionally, after obtaining the temperature information when the display screen displays the display information, the brightness and chromaticity compensation coefficient and the uniformity compensation coefficient corresponding to the temperature information are obtained. For example, based on the temperature information when the display screen displays the display information, the required compensation coefficient can be calculated if it is necessary to eliminate the brightness and chromaticity deviation caused by the temperature information under the temperature information, that is, the brightness and chromaticity compensation coefficient can be calculated, and based on the temperature information when the display screen displays the display information, the required compensation coefficient can be calculated if it is necessary to eliminate the uniformity inconsistency caused by the temperature information under the temperature information, that is, the uniformity compensation coefficient can be calculated.

[0047] Step S108 : compensating the brightness and chromaticity information based on the brightness and chromaticity compensation coefficients, and compensating the uniformity information based on the uniformity compensation coefficients.

[0048] In the technical solution provided in the above step S108 of the present application, the above compensation can be used to represent the compensation performed on the RGB data in the target image displayed on the display screen.

[0049] Optionally, after obtaining the brightness and chromaticity compensation coefficient and the uniformity compensation coefficient corresponding to the temperature information, the brightness and chromaticity information is compensated based on the brightness and chromaticity compensation coefficient, and the uniformity information is compensated based on the uniformity compensation coefficient. For example, the current brightness and chromaticity information can be compensated according to the brightness and chromaticity compensation coefficient, and the current uniformity information can be compensated according to the uniformity compensation coefficient, so that the above-mentioned RGB data can be compensated, thereby completing the correction of the display information of the display screen.

[0050] FIG2( a ) is a schematic diagram of the architecture of a control device for a display screen according to an embodiment of the present application. As shown in FIG2( a ), the control device for the display screen may be a receiving card. In this architecture, the Transformer (TF) modules 201 to 202 may receive data from the transmitting end through a Fibre Channel Interface (FCI) high-density connector. The TF module 201 may send data to a Field Programmable Gate Array (FPGA) module 205 through a port physical layer (PHY) module 203. The TF module 202 may send data to an FPGA module 205 through a PHY module 204. The FPGA module 205 may be used for algorithm processing and calculation, and may send the processed data to a driver chip 206 of an LED display screen, thereby controlling the display of the LED screen. The Micro Controller Unit (MCU) 207 may be responsible for parameter preprocessing and data acquisition and acquisition of sensor parameters. The Synchronous Dynamic Random Access Memory (SDRAM) may be used for data processing and calculation of the algorithm. Memory (SDRAM for short) / Double Data Rate Synchronous Dynamic Random Access Memory (DDR for short) 208 and external flash memory (Flash) 209 can be used to store some parameters.

[0051] Figure 2(b) is a schematic diagram of the internal structure of an FPGA according to an embodiment of the present application. As shown in Figure 2(b), the above-mentioned FPGA module is provided with: a receiving sub-module (for example, a Receive sub-module) 2051, a bus control sub-module (for example, a Bus Control sub-module) 2052, a conversion sub-module (for example, a Convert sub-module) 2053 and a scanning sub-module (for example, a Scann sub-module) 2054, wherein the receiving sub-module 2051 is used to unpack and obtain image data, the bus control sub-module 2052 is used to store image data, the conversion sub-module 2053 is used to process multiple serial algorithms, and the scanning sub-module 2054 is used to control the driver chip of the display screen.

[0052] Optionally, through the conversion submodule 2053, the brightness and chromaticity information can be compensated according to the brightness and chromaticity compensation coefficient, and the uniformity information can be compensated according to the uniformity compensation coefficient, so that the above-mentioned RGB data can be compensated, thereby completing the correction of the display information of the display screen.

[0053] FIG3 is a flow chart of a temperature compensation method according to an embodiment of the present application. As shown in FIG3 , the temperature compensation method may include the following steps:

[0054] Step S301: Count the image content.

[0055] After counting the image contents, the process proceeds to step S302.

[0056] Step S302: Calculate the screen temperature.

[0057] In this embodiment, based on the display information when the target image is displayed on the display screen, the power consumption of the display screen under the current display can be calculated, and then based on the power consumption and temperature prediction model, the temperature information of the display screen when displaying the display information can be calculated, that is, the screen temperature under the current power consumption can be calculated.

[0058] After calculating the screen temperature, proceed to step S303.

[0059] Step S303: Calculate brightness and chromaticity compensation coefficients.

[0060] In this embodiment, based on the temperature information when the display screen displays the display information, that is, based on the screen temperature under the current power consumption, the compensation coefficient required to eliminate the brightness and chromaticity deviation caused by the temperature at the screen temperature can be calculated, that is, the brightness and chromaticity compensation coefficient can be calculated.

[0061] After calculating the brightness and chromaticity compensation coefficients, the process proceeds to step S304.

[0062] Step S304: Compensate the brightness and chromaticity information.

[0063] In this embodiment, the brightness and chromaticity deviation caused by temperature is eliminated by using the brightness and chromaticity compensation coefficient, thereby compensating for the brightness and chromaticity information.

[0064] After compensating the brightness and chromaticity information, the process proceeds to step S305.

[0065] Step S305: Calculate the thermal uniformity compensation coefficient.

[0066] In this embodiment, based on the temperature information when the display screen displays the display information, that is, based on the screen temperature at the current power consumption, the compensation coefficient required to eliminate the uniformity inconsistency caused by the temperature can be calculated at the screen temperature, that is, the thermal uniformity compensation coefficient can be calculated.

[0067] After calculating the thermal uniformity compensation coefficient, proceed to step S306.

[0068] Step S306: Compensate for the uniform information.

[0069] In this embodiment, the uniformity inconsistency caused by temperature is eliminated by using the thermal uniformity compensation coefficient, thereby compensating for the uniformity information.

[0070] Optionally, the temperature compensation method may specifically include the following steps:

[0071] Step 1: Considering that power consumption is strongly correlated with the heat generation of LEDs, the power consumption under the current display is first calculated based on the actual display content on the screen (eg, color information and grayscale information).

[0072] Step 2: Calculate the screen temperature under the current display power consumption based on the established temperature prediction model.

[0073] Step 3: Based on the screen temperature value obtained by the above calculation, calculate the compensation coefficient required to eliminate the brightness and chromaticity deviation caused by the temperature at the current screen temperature.

[0074] Step 4: Use the compensation coefficient to compensate the original display grayscale, thereby solving the problem of brightness and color temperature caused by temperature, and the instability of changes with temperature and time.

[0075] Step 5: In addition to affecting the overall brightness and color temperature, temperature also affects the uniformity of the screen. Therefore, it is necessary to calculate the uniformity compensation coefficient.

[0076] Step six: Use the uniformity compensation coefficient to compensate for the uniformity of the screen, thereby solving the problem of screen display uniformity caused by temperature changes.

[0077] In related technologies, compensation is typically performed only for uniformity in thermal equilibrium (i.e., when the screen temperature no longer fluctuates and stabilizes). This ensures that the problem of display unevenness caused by temperature in thermal equilibrium is resolved. However, this method fails to consider that the screen temperature can change over time. For example, from power-on to thermal equilibrium, the screen temperature gradually rises. During this process, the screen temperature constantly changes, and the display uniformity also changes with the temperature change, resulting in a technical problem of low display quality.

[0078] Furthermore, in related art, the correction compensation coefficient is typically modified based on the grayscale displayed on the screen. This solution assumes that the displayed grayscale and temperature exhibit an absolutely linear relationship. In this solution, the larger the grayscale displayed by the LED, the higher the screen temperature, and vice versa. That is, based on the existing technology, this solution only considers temperature, but does not take into account that the heat generation and heat dissipation of the LED screen require a certain amount of time to respond (also known as reaction). For example, when suddenly switching from a smaller grayscale to a larger grayscale, the brightness on the screen does not suddenly increase instantly, but rather increases over a relatively slow process. Therefore, the technical problem of low display quality still exists.

[0079] However, in the solution implemented by the above-mentioned steps S102 to S108 of the present application, the display information when the target image is displayed on the display screen is first obtained, and then the temperature information when the display screen displays the display information is obtained, and the brightness and chromaticity compensation coefficients and uniformity compensation coefficients corresponding to the temperature information are obtained. Then, the brightness and chromaticity information are compensated by the brightness and chromaticity compensation coefficients, and the uniformity information is compensated by the uniformity compensation coefficients. In this way, the purpose of compensating the brightness and chromaticity and uniformity of the display screen is achieved, thereby solving the technical problem of low display quality of the display screen, and further achieving the technical effect of improving the display quality of the display screen.

[0080] The above method of this embodiment is further introduced below.

[0081] As an optional embodiment, the brightness and chromaticity compensation coefficient is obtained by converting the sub-brightness and chromaticity compensation coefficient, and the sub-brightness and chromaticity compensation coefficient is used to represent the correlation between the brightness and chromaticity information and temperature information of the display screen, and / or, the uniformity compensation coefficient is determined based on the sub-uniformity compensation coefficient of the pixel in the target image, and the sub-uniformity compensation coefficient is used to compensate for the uniformity information corresponding to the pixel.

[0082] In this embodiment, the above-mentioned sub-brightness chromaticity compensation coefficient can be used to generate a brightness chromaticity compensation coefficient, the above-mentioned sub-brightness chromaticity compensation coefficient can be used to represent the correlation between the brightness chromaticity information and temperature information of the display screen, the above-mentioned sub-uniformity compensation coefficient can be used to generate a uniformity compensation coefficient, and the above-mentioned sub-uniformity compensation coefficient can be used to compensate for the uniformity information corresponding to the pixel. For example, the above-mentioned sub-brightness chromaticity compensation coefficient can be represented by a temperature compensation coefficient matrix [γ], and the above-mentioned sub-uniformity compensation coefficient can be represented by a correction compensation coefficient matrix [α].

[0083] Optionally, by converting the sub-brightness and chromaticity compensation coefficients, a brightness and chromaticity compensation coefficient can be obtained, and / or, based on the sub-uniformity compensation coefficients of the pixels in the target image, a uniformity compensation coefficient can be determined, thereby achieving the technical effect of compensating for the brightness and chromaticity and uniformity of the display screen.

[0084] In this embodiment, it is necessary to determine a brightness and chromaticity compensation coefficient to perform brightness and chromaticity compensation on the display information displayed on the display screen. The following further introduces how to determine the brightness and chromaticity compensation coefficient.

[0085] As an optional embodiment, the information processing method of the display screen may also include: obtaining brightness and chromaticity samples and temperature samples of the display screen; obtaining a brightness and chromaticity compensation coefficient corresponding to the temperature information, including: determining the brightness and chromaticity compensation coefficient corresponding to the temperature information based on the sub-brightness and chromaticity compensation coefficients corresponding to the brightness and chromaticity samples and the temperature samples.

[0086] In this embodiment, the brightness and chromaticity samples and the temperature samples may satisfy an association relationship. The brightness and chromaticity samples may include brightness samples and / or chromaticity samples of the display screen. For example, the brightness and chromaticity samples may be RGB tristimulus value data, and the temperature samples may be represented by Tmeai.

[0087] Optionally, RGB tristimulus value data and temperature sample Tmeai are obtained, and then the sub-brightness chromaticity compensation coefficient can be determined based on the RGB tristimulus value data and temperature sample Tmeai, that is, the temperature compensation coefficient matrix [γ] can be determined, and then based on the temperature compensation coefficient matrix [γ] and the temperature information, the brightness chromaticity compensation coefficient corresponding to the temperature information can be determined, thereby achieving the technical effect of performing brightness chromaticity compensation on the display information displayed on the display screen by determining the brightness chromaticity compensation coefficient.

[0088] Optionally, by performing linear fitting on the luminance and chromaticity samples and the temperature samples, a slope matrix corresponding to the RGB tristimulus value data can be obtained. For example, by fitting the RGB tristimulus value data and the temperature samples Tmeai, a slope matrix [K] corresponding to the RGB tristimulus value data can be obtained.

[0089] Alternatively, the temperature compensation coefficient [γ] can be obtained by the following formula:

[0090] Among them, [K] can be used to represent the slope matrix, It can be used to represent the red, green and blue three stimulus values, wherein the slope matrix [K] can be obtained by linear fitting the red, green and blue three stimulus values ​​and the corresponding screen temperature data Tmeai. The above linear fitting process is for the red, green and blue three stimulus values The process of fitting the 9 components separately.

[0091] Optionally, when the temperature of the display screen increases by 1° C., the relative changes in the tristimulus values ​​are also different.

[0092] Optionally, the above process is based on the compensation of brightness and chromaticity. If only brightness compensation is performed, the corresponding collected red, green and blue three stimulus data are Change to The corresponding elements on the non-main diagonal lines in [K], [γ], and [δ] are 0. This application does not impose any restrictions on whether compensation is for brightness or brightness and chromaticity, and can be selected according to needs.

[0093] In this embodiment, the brightness and chromaticity compensation coefficients need to be determined based on the sub-brightness and chromaticity compensation coefficients. The following further describes how to determine the brightness and chromaticity compensation coefficients based on the sub-brightness and chromaticity compensation coefficients.

[0094] As an optional implementation, based on the sub-brightness chromaticity compensation coefficients corresponding to the brightness chromaticity samples and the temperature samples, the brightness chromaticity compensation coefficient corresponding to the temperature information is determined, including: determining the brightness chromaticity compensation coefficient corresponding to the temperature information based at least on the sub-brightness chromaticity compensation coefficient and the reference temperature of the display screen.

[0095] In this embodiment, the reference temperature can be used to represent the temperature information of the display screen when the brightness and chromaticity information and / or uniformity information are in a normal state. For example, the reference temperature can be expressed as T_LED base To express.

[0096] Optionally, after obtaining the brightness and chromaticity samples and temperature samples of the display screen, the brightness and chromaticity compensation coefficient corresponding to the temperature information is determined based on at least the sub-brightness and chromaticity compensation coefficients corresponding to the brightness and chromaticity samples and the temperature samples.

[0180] Optionally, the temperature of the screen can affect the uniformity of the screen and cause inconsistencies in the brightness and color temperature of the screen. For example, the heat generated by the screen itself, the heat generated in different areas, and the heat dissipation will all affect the final temperature of the screen, and the final temperature will affect the uniformity and changes in brightness and color. For example, the heat generated by the screen itself can include the heat generated by light-emitting devices, etc. The heat generated in different areas can be affected by the displayed content, that is, the temperature will be higher in areas with rich color details. Heat dissipation can be affected by the structure of the cabinet. For example, due to the different structures of different areas of the cabinet, the heat dissipation coefficients of different materials are also different.

[0198] In this embodiment, after obtaining the color information when the display screen displays the target image, the temperature information when the display screen displays the color information is obtained. For example, based on the color information when the target image is displayed on the display screen, the power consumption of the display screen under the current display can be calculated, and then based on the power consumption and temperature prediction model, the temperature information when the display screen displays the color information can be calculated, that is, the temperature of the display screen under the current power consumption can be calculated, wherein the temperature prediction model can be used to represent the mapping relationship between temperature samples of multiple sub-display areas of the display screen, power consumption samples corresponding to different display information samples, and ambient temperature samples of the environment in which the display screen is located.

That is, the brightness and chromaticity compensation coefficient can be calculated.

[0204] Step S508 : Compensate the brightness and chromaticity information based on the brightness and chromaticity compensation coefficients.

[0205] In the technical solution provided in the above step S508 of the present application, the above compensation can be used to represent the compensation for the brightness and chromaticity information in the target image displayed on the display screen.
