[0030] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below 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 of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0032] 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.

[0033] Figure 1 FIG. 1 is a flow chart of a method for processing information of a display screen according to an embodiment of the present invention. Figure 1 As shown, the method may include the following steps:

[0034] Step S102, obtaining display information when the target image is displayed on the display screen.

[0035] In the technical solution provided in the above step S102 of the present invention, the above display information may include: color information of the display screen, grayscale information of the display screen, content shown in the image of the display screen, image data of the display screen, brightness and chromaticity information of the display screen, and uniformity information of the display screen, etc. The above uniformity information may be used to indicate the uniformity of the display screen displaying the target image. For example, the brightness and chromaticity information may include brightness information and / or chromaticity (or, may also be referred to as color temperature) information of the display screen. The uniformity information may be used to indicate whether the brightness and chromaticity information of the target image is consistent when different display areas in the display screen display the target image. The evaluation index 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 Blue, referred to as RGB) image data (or, may also be referred to as RGB data signal), which is only used as an example here and is not specifically limited.

[0036] 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 here. 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 a grayscale histogram or other method to obtain grayscale information. In addition, by detecting different areas in the display screen with a uniformity testing device, uniformity information can be obtained.

[0037] Step S104, obtaining temperature information when the display screen displays information.

[0038] In the technical solution provided in the above step S104 of the present invention, the above brightness and chromaticity information and the above uniformity information may change with the change of the temperature information of the display screen. The above temperature information may be used to indicate the temperature of the display screen at a certain power consumption. For example, the above brightness information and / or the above chromaticity information, as well as the uniformity of the target image displayed by the above display screen, may change with the change of the temperature information of the display screen.

[0039] 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.

[0040] 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 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.

[0041] Step S106, obtaining brightness and chromaticity compensation coefficients and uniformity compensation coefficients corresponding to the temperature information.

[0042] In the technical solution provided in the above step S106 of the present invention, 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.

[0043] In this embodiment, the correlation between the brightness and chromaticity information and the temperature information may be that the change in temperature information is linearly related to the change in brightness and chromaticity. For example, for every 1°C increase in the temperature information of the display screen, the relative change in the three stimulus values ​​of RGB in the pixel is also different. The pixel value may be the main component of RGB collected by the camera in a cold screen state, and the pixel value may also be the main component of RGB collected by the camera in a hot screen state.

[0044] 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, if it is necessary to eliminate the brightness and chromaticity deviation caused by the temperature information under the temperature information, the required compensation coefficient can be calculated, 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, if it is necessary to eliminate the uniformity inconsistency caused by the temperature information under the temperature information, the required compensation coefficient can be calculated, that is, the uniformity compensation coefficient can be calculated.

[0045] 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.

[0046] In the technical solution provided in the above step S108 of the present invention, the above compensation can be used to represent the compensation performed on the RGB data in the target image displayed on the display screen.

[0047] 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, according to the brightness and chromaticity compensation coefficient, the current brightness and chromaticity information can be compensated, and according to the uniformity compensation coefficient, the current uniformity information can be compensated, so that the above-mentioned RGB data can be compensated, thereby completing the correction of the display information of the display screen.

[0048] FIG2(a) is a schematic diagram of the architecture of a control device for a display screen according to an embodiment of the present invention. As shown in FIG2(a), the control device for the display screen may be a receiving card. In the architecture, the transmission (Transformer, referred to as TF) modules 201 to 202 may receive data from the transmitting end through a Fibre Channel Interface (FCI) high-density connector. The TF module 301 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 the 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 microcontroller (MCU) 207 may be responsible for parameter preprocessing, as well as data collection and acquisition of sensor parameters. The synchronous dynamic random access memory (SDRAM) may be used for the processing and calculation of algorithms. Double Data Rate Synchronous Dynamic Random Access Memory (SDRAM) / Double Data Rate Synchronous Dynamic Random Access Memory (DDR) 208 and external flash memory (Flash) 209 can be used to store some parameters.

[0049] FIG2(b) is a schematic diagram of the internal structure of an FPGA according to an embodiment of the present invention. As shown in FIG2(b), the FPGA module is provided with: a receiving submodule (e.g., a Receive submodule) 2051, a bus control submodule (e.g., a Bus Control submodule) 2052, a conversion submodule (e.g., a Convert submodule) 2053, and a scanning submodule (e.g., a Scann submodule) 2054, wherein the receiving submodule 2051 is used to unpack and acquire image data, the bus control submodule 2052 is used to store image data, the conversion submodule 2053 is used to process a variety of serial algorithms, and the scanning submodule 2054 is used to control the driver chip of the display screen.

[0050] 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 RGB data can be compensated, thereby completing the correction of the display information of the display screen.

[0051] Figure 3 is a flow chart of a temperature compensation method according to an embodiment of the present invention. Figure 3 As shown, the temperature compensation method may include the following steps:

[0052] Step S301, counting image content.

[0053] After counting the image contents, the process proceeds to step S302.

[0054] Step S302, calculating the screen temperature.

[0055] 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.

[0056] After calculating the screen temperature, proceed to step S303.

[0057] Step S303, calculating brightness and chromaticity compensation coefficients.

[0058] In this embodiment, based on the temperature information when the display screen displays information, that is, based on the screen temperature under the current power consumption, the required compensation coefficient can be calculated at the screen temperature if it is necessary to eliminate the brightness and chromaticity deviation caused by the temperature, that is, the brightness and chromaticity compensation coefficient can be calculated.

[0059] After calculating the brightness and chromaticity compensation coefficients, proceed to step S304.

[0060] Step S304, compensating the brightness and chromaticity information.

[0061] In this embodiment, the brightness and chromaticity deviation caused by the temperature is eliminated by using the brightness and chromaticity compensation coefficient, so that the brightness and chromaticity information can be compensated.

[0062] After compensating the brightness and chromaticity information, proceed to step S305.

[0063] Step S305, calculating the thermal uniformity compensation coefficient.

[0064] In this embodiment, according to the temperature information when the display screen displays the display information, that is, according to the screen temperature under the current power consumption, the required compensation coefficient can be calculated if the uniformity inconsistency caused by the temperature needs to be eliminated at the screen temperature, that is, the thermal uniformity compensation coefficient can be calculated.

[0065] After calculating the thermal uniformity compensation coefficient, proceed to step S306.

[0066] Step S306, compensating for the uniform information.

[0067] In this embodiment, the uniformity inconsistency caused by temperature is eliminated by using the thermal uniformity compensation coefficient, so that the uniformity information can be compensated.

[0068] Optionally, the temperature compensation method may specifically include the following steps:

[0069] Step 1: Considering that power consumption is strongly correlated with the heat generation of LEDs, firstly, the power consumption under the current display is calculated according to the actual display content on the screen (eg, color information and grayscale information).

[0070] Step 2: Then, according to the established temperature prediction model, the screen temperature under the current display power consumption is calculated.

[0071] Step three, 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.

[0072] Step 4: Use the compensation coefficient to compensate the original display grayscale, so as to solve the problem of brightness and color temperature caused by temperature, and the instability of changes with temperature and time.

[0073] Step 5: In addition to affecting the overall brightness and color temperature, temperature will also affect the uniformity of the screen. Therefore, it is necessary to calculate the uniformity compensation coefficient.

[0074] 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.

[0075] In the related art, compensation is usually only performed for uniformity in the thermal equilibrium state (that is, when the temperature on the screen no longer changes and tends to be stable), thereby ensuring that the problem of uneven display caused by temperature in the thermal equilibrium state is solved. However, the above method does not take into account that the temperature on the screen will change over time. For example, from power-on to the thermal equilibrium state, the temperature of the screen gradually rises. During this process, the temperature of the screen is constantly changing, and the uniformity of the screen display also changes with the change in temperature, resulting in a technical problem of low display quality of the display screen.

[0076] In addition, in the related art, the correction compensation coefficient is usually corrected according to the grayscale displayed on the screen. This scheme assumes that the displayed grayscale and temperature present an absolute linear relationship. In this scheme, the larger the grayscale displayed by the LED, the higher the temperature of the screen, and vice versa. That is, based on the existing technology, this scheme only takes into account the temperature, but does not take into account that the heating and heat dissipation of the LED screen requires a certain time response (also known as reaction). For example, when suddenly switching from a smaller grayscale to a larger grayscale, the brightness on the screen will not suddenly increase instantly, but a relatively slow increase process. Therefore, there is still a technical problem of low display quality of the display screen.

[0077] However, in the scheme 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 coefficient and the uniformity compensation coefficient corresponding to the temperature information are obtained, and then the brightness and chromaticity information is compensated by the brightness and chromaticity compensation coefficient, and the uniformity information is compensated by the uniformity compensation coefficient, thereby achieving the purpose of compensating the brightness and chromaticity and uniformity of the display screen, 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.

[0078] The above method of this embodiment is further introduced below.

[0079] As an optional implementation, the brightness chromaticity compensation coefficient is converted from the sub-brightness chromaticity compensation coefficient, and the sub-brightness chromaticity compensation coefficient is used to represent the correlation between the brightness chromaticity information and the 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.

[0080] 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 the 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 uniform 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].

[0081] Optionally, by converting the sub-brightness chromaticity compensation coefficient, a brightness chromaticity compensation coefficient can be obtained, and / or, based on the sub-uniformity compensation coefficient of the pixel in the target image, a uniformity compensation coefficient can be determined, thereby achieving the technical effect of compensating for the brightness chromaticity and uniformity of the display screen.

[0082] 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.

[0083] As an optional implementation, the information processing method of the display screen may further 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.

[0084] In this embodiment, the brightness and chromaticity samples may satisfy an association relationship with the temperature samples. 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 Tmea i To express.

[0085] Optionally, obtain RGB tristimulus value data and temperature sample Tmea i Then, according to the RGB tristimulus value data and temperature sample Tmea i , the sub-brightness chromaticity compensation coefficient can be determined, that is, the temperature compensation coefficient matrix [γ] can be determined, and then according to 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.

[0086] Optionally, by performing linear fitting on the brightness and chromaticity samples and the temperature samples, a slope matrix corresponding to the tristimulus value data of RGB can be obtained. For example, by performing linear fitting on the tristimulus value data of RGB and the temperature sample Tmea i, we can get the slope matrix [K] corresponding to the RGB tristimulus value data.

[0087] Alternatively, the temperature compensation coefficient [γ] can be obtained by the following formula:

[0088]

[0089] 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, where the slope matrix [K] can be obtained by the red, green and blue three stimulus values ​​and the corresponding screen temperature data Tmea i , and the linear fitting process is to obtain the red, green and blue three stimulus values The process of fitting the 9 components separately.

[0090] Optionally, when the temperature of the display screen increases by 1° C., the relative changes in the tristimulus values ​​are different.

[0091] 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 is 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 it is brightness compensation or brightness chromaticity compensation, and it can be selected according to needs.

[0092] In this embodiment, it is necessary to determine the brightness chromaticity compensation coefficient according to the sub-brightness chromaticity compensation coefficient. The following further introduces how to determine the brightness chromaticity compensation coefficient according to the sub-brightness chromaticity compensation coefficient.

[0093] As an optional implementation, based on the sub-brightness chromaticity compensation coefficients corresponding to the brightness chromaticity sample and the temperature sample, 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.

[0094] In this embodiment, the reference temperature can be used to indicate 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.

[0193] 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 heating of the display screen itself, the heating of 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 chromaticity. For example, the heating of the display screen itself can include heating of light-emitting devices, etc. The heating of 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.

[0204] Figure 5 FIG. 1 is a flow chart of a method for thermal compensation correction of a display screen according to an embodiment of the present invention. Figure 5 As shown, the thermal compensation correction method of the display screen may include the following steps:

[0205] Step S502, obtaining color information when the display screen displays the target image.

[0206] In the technical solution provided in the above step S502 of the present invention, the above target image can be used to represent an image corresponding to the content actually displayed on the screen. The above target image can be a normal image or a test-specific image screen. The above color information can at least include brightness and chromaticity information in the target image.

[0207] In this embodiment, the color information of the target image is obtained when the display screen displays the target image. For example, when the display screen displays a certain image, the color information of the image is obtained, that is, at least the brightness and chromaticity information of the image is obtained.

[0208] Optionally, through image processing technology, the brightness and chromaticity information of the display screen when displaying the target image can be obtained in real time.

[0209] Step S504, obtaining temperature information when the display screen displays color information.

[0210] In the technical solution provided in step S504 of the present invention, the temperature information may be used to indicate the temperature of the display screen at a certain power consumption. For example, the brightness information and / or the chromaticity information may change as the temperature information of the display screen changes.

[0211] 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.

[0212] 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 color information can be calculated. For example, by inputting the power consumption into the temperature prediction model for prediction processing, the temperature information of the display screen under the current power consumption can be obtained.

[0213] Step S506, obtaining brightness and chromaticity compensation coefficients corresponding to the temperature information.

[0214] In the technical solution provided in the above step S506 of the present invention, the above brightness and chromaticity compensation coefficient can be determined based on the correlation between the brightness and chromaticity information and the temperature information in the color information. The above brightness and chromaticity information may include the brightness information and / or chromaticity information of the display screen. For example, the above brightness and chromaticity compensation coefficient may also be called a brightness and color temperature compensation coefficient.

[0215] In this embodiment, the correlation between the above-mentioned brightness and chromaticity information and the temperature information can be that the change in temperature information is linearly related to the change in brightness and chromaticity. For example, for every 1°C increase in the temperature information of the display screen, the relative change in the three stimulus values ​​of RGB in the pixel is also different. The pixel value can be the main component of RGB collected by the camera in the cold screen state, and the pixel value can also be the main component of RGB collected by the camera in the hot screen state.

[0216] Optionally, after obtaining the temperature information when the display screen displays color information, the brightness and chromaticity compensation coefficient corresponding to the temperature information is obtained. For example, based on the temperature information when the display screen displays color information, the required compensation coefficient can be calculated under the temperature information if it is necessary to eliminate the brightness and chromaticity deviation caused by the temperature information. That is, the brightness and chromaticity compensation coefficient can be calculated.

[0217] Step S508: Compensate the brightness and chromaticity information based on the brightness and chromaticity compensation coefficients.

[0218] In the technical solution provided in the above step S508 of the present invention, the above compensation can be used to indicate compensation for brightness and chromaticity information in the target image displayed on the display screen.

[0219] In this embodiment, after obtaining the brightness and chromaticity compensation coefficient corresponding to the temperature information, the brightness and chromaticity information is compensated based on the brightness and chromaticity compensation coefficient. For example, according to the brightness and chromaticity compensation coefficient, the current brightness and chromaticity information can be compensated in real time, thereby completing the correction of the color information displayed on the display screen.

[0244] As an optional implementation, obtaining temperature information when the display screen displays color information includes: determining the power consumption of the display screen based on the color information; and determining temperature information when the display screen operates under the power consumption.
