[0033] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0034] During the image acquisition process, since the human eye's perception of brightness and physical power are nonlinear, if the received light signal is directly stored in a linear relationship of 0 to 255 (0 is black, 255 is white), such as the value of white with a brightness of 20% is 255×0.2=51. Then the level of middle gray perceived by the human eye is 51, which results in 205 levels in the bright area and only 50 levels in the dark area. In order to solve the problem of waste of levels in the bright area and low resolution in the dark area, gamma encoding is usually performed to increase the level of middle gray perceived by the human eye, so that the level distribution of the bright and dark areas is uniform, thereby improving the resolution of the image. That is, gamma encoding can redistribute the grayscale into a state that the eyes are accustomed to, and realize efficient storage of grayscale. When the display screen displays the image, gamma decoding is required to adjust the brightness of the image (that is, the conversion is reversed through the opposite nonlinear conversion).

[0035] A complete image processing process includes three stages: image acquisition, storage and transmission, and display output. Gamma correction can be performed at different stages of the process. The following is a further illustrative explanation with the help of diagrams. In the image acquisition stage, taking the camera as an example, since the sensor is a linear element, the raw data obtained by shooting is linear, that is, the RAW file stores linear data. In this case, it is necessary to use the file gamma to perform gamma correction during the conversion to IPG / JPEG (i.e., gamma correction during the gamma encoding process). The conversion is as follows: Figure 1a The nonlinear curve is shown. Figure 1a is a schematic diagram of a first stage curve of a correction process according to an exemplary embodiment. Figure 1aAs shown in , the nonlinear curve inputs the original scene brightness and outputs the value of the file input after the file gamma correction. It should be noted that gamma correction is generally not performed in the storage and transmission stage. Further, in the display output stage, taking viewing an image as an example, display gamma is usually used for gamma correction (i.e. gamma correction in the gamma decoding process). The nonlinear curve is as follows Figure 1b shown. Figure 1b is a schematic diagram of a second stage curve of a correction process according to an exemplary embodiment. Figure 1b As shown, the nonlinear curve is Figure 1a On the contrary, it is equivalent to Figure 1a The nonlinear transformation is performed in the opposite direction, using Figure 1a The converted file input value is used as input to obtain the output of the corrected display brightness, so that the gamma correction at each stage generates a final gamma of 1. The correction result is as follows Figure 1c shown. Figure 1c is a schematic diagram of a correction result curve according to an exemplary embodiment. Figure 1c As shown, Figure 1a and Figure 1b The whole correction process makes the input and output images consistent.

[0036] This correction process is applied in various scenarios, such as in OLED displays. However, in OLED displays, different refresh rates require different gamma parameters. Therefore, when the display is shipped, the corresponding gamma parameters need to be configured for different refresh rates, so that when the display is switched to a different refresh rate, the corresponding gamma parameters can be obtained to correct the display brightness of the display at different refresh rates.

[0037] In the related art, gamma correction is performed for gamma parameters corresponding to different refresh rates, so that the human eye cannot feel the visual effect problems caused by the refresh rate switching. This method not only requires a large number of steps to calculate the gamma parameters corresponding to different refresh rates, but also because gamma correction can only adjust the grayscale value (i.e. brightness) of each color value of the display screen, this method can only alleviate the screen brightness difference problem caused by the refresh rate switching, but cannot alleviate the screen color cast problem caused by the refresh rate switching.

[0038] Based on this, the present disclosure provides a display method. The display method of the present disclosure can adjust the display parameters of the display screen based on the color parameters, shorten the process time, alleviate the visual effect difference problem caused by the refresh rate switching of the display screen, and thus improve the display visual effect of the display screen.

[0039] In each embodiment of the present disclosure, the display visual effect of the display screen may be a visual effect that can be perceived by the human body, such as display color, display brightness, and display color temperature, which is not limited in the present disclosure.

[0040] In various embodiments of the present disclosure, for ease of understanding, gamma parameters may be used to replace color parameters.

[0041] Figure 2 is a flow chart of a display method according to an exemplary embodiment. Figure 2 As shown, the display method is applied in a terminal and includes the following steps.

[0042] In step S11 , a target refresh rate is obtained.

[0043] In the disclosed embodiment, when the terminal detects that the system needs to load display visual effects at a certain refresh rate, the target refresh rate is obtained. Alternatively, the terminal may detect that the system sends a refresh rate switching instruction, and the target refresh rate is obtained.

[0044] In step S12, a first display parameter at a target refresh rate is obtained.

[0045] In the embodiment of the present disclosure, the first display parameter is a parameter that may cause the display visual effect of the display screen to change. For example, it may be one or more parameter values ​​of parameters such as the RGB value, color balance value, brightness value, etc. of the image, which is not limited in the present disclosure.

[0046] In the disclosed embodiment, the method for obtaining the first display parameter at the target refresh rate is not limited. For example, the terminal may obtain the first display parameter at the target refresh rate locally or from a network.

[0047] In step S13, a second display parameter is obtained based on the first display parameter and a preset color parameter.

[0048] The color parameters are used to adjust the display parameters at different target refresh rates. For example, the color parameters can be used to perform gamma correction on the display parameters at 30 Hz, and can also be used to perform gamma correction on the display parameters at 60 Hz.

[0049] In the embodiment of the present disclosure, the color parameter is a gamma parameter corresponding to a reference refresh rate, wherein it should be noted that the reference refresh rate is a preset refresh rate.

[0050] In one embodiment, the reference refresh rate may be a fixed refresh rate selected when the display screen leaves the factory, or may be a set fixed refresh rate. The gamma parameter is a gamma parameter configured in the memory of the display screen based on the reference refresh rate when the display screen leaves the factory. For example, when the display screen leaves the factory, a fixed refresh rate of 120 Hz is selected, that is, the display visual effect at the 120 Hz refresh rate is used as a reference, the gamma parameter corresponding to 120 Hz is configured, and the configured gamma parameter is stored in the memory for subsequent direct reading.

[0051] It should be noted that the screen refresh rate is generally divided into 60hz and 120hz, of which 120hz and above are high refresh rates, that is, a screen with a refresh rate of 120hz can display a higher number of frames per unit time, the picture is smoother, and it is not easy to have deviation problems in display visual effects. It has good hand tracking and smoothness, and can be applied to a variety of scenarios. Therefore, a refresh rate of 120hz is generally selected as the base refresh rate. At the same time, in the register of the display driver chip (display driver integrated circuit, DDIC), only the gamma parameters corresponding to the base refresh rate need to be configured. Since a set of gamma parameters occupies a large amount of memory space, some DDICs only support the storage of gamma parameters corresponding to 2 to 3 refresh rates. Therefore, in the solution disclosed in the present invention, only the gamma parameters corresponding to the base refresh rate need to be configured, which can effectively save memory space.

[0052] In step S14, display is performed based on the second display parameter.

[0053] In the embodiment of the present disclosure, the display may be performed based on the complete parameters of the second display parameter, or may be performed based on partial parameters of the second display parameter. The specific display method is not limited in the embodiment of the present disclosure.

[0054] In the embodiment of the present disclosure, the order of executing step S11 and step S12 is not limited. Step S11 may be executed first and then step S12, or step S12 may be executed first and then step S11, or step S11 and step S12 may be executed simultaneously.

[0055] The display method provided by the embodiment of the present disclosure directly obtains the gamma parameters stored in the memory, adjusts the display parameters of the display screen, and thus improves the display visual effect of the display screen and improves the user experience.

[0056] In the embodiment of the present disclosure, the implementation process of obtaining the second display parameter based on the first display parameter and the preset color is specifically described below.

[0057] Figure 3is a flow chart showing a method for adjusting based on color parameters according to an exemplary embodiment. Figure 3 As shown, the following steps are included.

[0058] In step S21, a third display parameter is determined based on the first display parameter and the first corresponding relationship.

[0059] In the embodiment of the present disclosure, the third display parameter is the display parameter of the first display parameter corresponding to the reference refresh rate, the reference refresh rate is the above-mentioned preset refresh rate, and the first corresponding relationship is the relationship between the display parameter at the target refresh rate and the display parameter at the reference refresh rate.

[0060] In the embodiment of the present disclosure, the color temperature compensation is mainly performed on the first display parameter based on the first corresponding relationship. Of course, other color compensations can also be performed on the first display parameter based on the first corresponding relationship, so that the display visual effects at different refresh rates can share the gamma parameters corresponding to the reference refresh rate. Therefore, the color temperature compensation of the embodiment of the present disclosure is not further limited.

[0061] It should be noted that different target refresh rates correspond to different first corresponding relationships, that is, different target refresh rates correspond to different relationships between display parameters at the target refresh rate and display parameters at the reference refresh rate.

[0062] In step S22, brightness compensation is performed on the third display parameter based on the color parameter to obtain a second display parameter.

[0063] In the embodiment of the present disclosure, the brightness compensation for the third display parameter is mainly performed on the third display parameter based on the color parameter to obtain the second display parameter.

[0064] In the disclosed embodiment, based on the relationship between the display parameters at the target refresh rate and the display parameters at the reference refresh rate, the display parameters at the target refresh rate are adjusted to the display parameters at the corresponding reference refresh rate, thereby completing the correction of the display parameters at the target refresh rate, thereby making the display visual effect at the target refresh rate close to the display visual effect at the reference refresh rate. Therefore, when performing gamma correction later, the gamma parameters corresponding to the reference refresh rate can be directly used for correction.

[0065] In the disclosed embodiment, the gamma parameters corresponding to the same reference refresh rate can be used for calibration by indirect adjustment, so that only one set of gamma parameters needs to be stored in the memory, saving storage space. At the same time, this process replaces the process of using gamma parameters corresponding to different refresh rates for calibration. There is no need to match different gamma parameters for different refresh rates, but directly uses the data pre-stored in the memory for calibration, which saves both calculation steps and display calibration time.

[0066] In the embodiment of the present disclosure, it is necessary to obtain the first corresponding relationship under the target refresh rate based on the target refresh rate, and further, the first corresponding relationship can be obtained based on a lookup table. Another method for adjusting based on color parameters is described below.

[0067] Figure 4 is a flow chart showing another method for adjusting based on color parameters according to an exemplary embodiment. Figure 4 As shown, the following steps are included.

[0068] In step S31, based on the target refresh rate, a lookup table corresponding to the target refresh rate is determined.

[0069] Among them, the lookup table is used to characterize the relationship between the display parameters at the target refresh rate and the display parameters at the reference refresh rate. In the embodiment of the present disclosure, the system configures different lookup tables for different refresh rates, so different target refresh rates correspond to different first corresponding relationships.

[0070] In step S32, a third display parameter is determined based on the first display parameter and the first corresponding relationship.

[0071] In step S33, brightness compensation is performed on the third display parameter based on the color parameter to obtain a second display parameter.

[0072] Wherein, step S32 and step S33 have been described in the method for adjusting based on color parameters in one embodiment, and thus will not be described in detail here.

[0073] It should be noted that, although the embodiment of the present disclosure uses the relationship between the display parameters at the target refresh rate and the display parameters at the reference refresh rate using the corresponding lookup table, it is not limited to the lookup table. For example, the relationship between the display parameters at the target refresh rate and the display parameters at the reference refresh rate may also be a functional relationship established with the help of a model, or a relationship established in other ways, which is not specifically limited in the present disclosure.

[0074] In one embodiment, a lookup table established by a 3DLUT model is taken as an example. It should be noted that LUT (Look-Up-Table) is essentially a lookup table, that is, a color value is input, the corresponding color value is found in the lookup table and output. LUT is divided into 1DLUT and 3DLUT. 1DLUT means that the three channel values ​​of R, G, and B do not affect each other and are independently mapped. 3DLUT is composed of three 1DLUTs, that is, the input RGB three channel color values ​​are mapped according to the three lookup tables of 3DLUT to obtain the converted color. For example, R, G, and B are used as the original color channel values, and r, g, and b are used as the converted color channel values. It can be understood that 1DLUT contains three mapping relationships f1(R)=r, f2(G)=g, and f3(B)=b. However, 3DLUT has a mapping relationship f(R, G, B) = (r, g, b), that is, in 3DLUT, any change in the value of one of the color channels will affect the values ​​of the three color channels, that is, any change in the value of any color channel will cause corresponding changes in the values ​​of other color channels.

[0075] Among them, 1DLUT can only control gamma value, RGB balance (grayscale) and white point, while 3DLUT can affect hue, saturation, brightness, etc. in a full three-dimensional color space control mode. That is, 3DLUT can affect color values, while 1DLUT can only affect brightness values. Therefore, 3DLUT is often used for accurate color correction. In the present disclosure, the 3DLUT model is selected to convert display parameters at different refresh rates into display parameters at the reference refresh rate to achieve accurate correction of display parameters of the display screen.

[0076] In the embodiment of the present disclosure, the implementation process of converting the display parameters at different refresh rates into the display parameters at the reference refresh rate by using the 3D LUT model is described.

[0077] In the piece-by-piece calibration process of the display screen, with the help of the 3DLUT model, the relationship between the display parameters at different refresh rates and the display parameters at the reference refresh rate, that is, the 3DLUT lookup table, is established and stored in the corresponding 3DLUT file. Among them, the establishment process includes: dividing the source RGB three-dimensional color space into grids according to a certain sampling interval; based on the cube interpolation algorithm, establishing the relationship between the source color space (display visual effects at different refresh rates) and the target color space (display visual effects at the reference refresh rate), and putting the data of the source color space and the data of the target color space into the table in order to form a 3DLUT lookup table, which corresponds to the 3DLUT file stored in the memory. Among them, different refresh rates correspond to different 3DLUT files.

[0078] In the disclosed embodiment, a relationship between display parameters at a target refresh rate and display parameters at a reference refresh rate is established with the help of a 3DLUT model to achieve accurate color compensation.

[0079] For ease of understanding, the implementation process of the above display method is comprehensively described below.

[0080] Figure 5 is a flowchart of another display method according to an exemplary embodiment. Figure 5 As shown, the display method includes the following steps.

[0081] In step S41, a reference refresh rate is selected and corresponding color parameters are configured.

[0082] In the embodiment of the present disclosure, when the display screen leaves the factory, a fixed refresh rate is selected as the reference refresh rate, and a gamma parameter corresponding to the reference refresh rate, i.e., a preset color parameter, is configured. The display visual effect at the reference refresh rate is used as the standard display visual effect to calibrate the display visual effect of the display screen.

[0083] In step S42, a relationship between display parameters at different refresh rates and display parameters at a reference refresh rate is established.

[0084] In step S43, a target refresh rate is determined, and a relationship between display parameters at the corresponding target refresh rate and display parameters at the reference refresh rate is determined.

[0085] In step S44, based on the relationship between the display parameters at the target refresh rate and the display parameters at the reference refresh rate, the display parameters of the display screen are preliminarily adjusted, and then the display parameters of the display screen are further adjusted according to the preset color parameters.

[0086] In the disclosed embodiment, a 3DLUT file corresponding to the target refresh rate is determined based on the target refresh rate, and the 3DLUT file contains a 3DLUT lookup table corresponding to the target refresh rate, and the 3DLUT lookup table includes the relationship between the display parameters at the target refresh rate and the display parameters at the reference refresh rate. Then, according to the different parameters of the image at the target refresh rate, the parameters at the corresponding reference refresh rate are searched in the 3D lookup table, and the corresponding conversion is performed. The conversion process realizes the adjustment of the display parameters of the display screen. Further, the gamma parameters pre-stored in the memory are obtained, that is, the gamma parameters of the reference refresh rate are determined, and gamma correction is performed based on the gamma parameters. The correction process realizes further adjustment of the display parameters of the display screen. It should be noted that before the display screen performs gamma correction, the display parameters at the target refresh rate have been adjusted based on the relationship between the display parameters at the target refresh rate and the display parameters at the reference refresh rate, which is equivalent to the display visual effect of the display screen matching the reference refresh rate at this time, so the gamma parameters at the reference refresh rate can be directly used for correction without matching the gamma parameters of the target refresh rate.

[0087] For ease of understanding, the following provides examples with reference to diagrams. Figure 6 FIG. 1 is a schematic diagram showing how to determine a gamma parameter according to a target refresh rate according to an exemplary embodiment. Figure 6 As shown, the application processor (AP) stores different refresh rates and 3D LUTs corresponding to different refresh rates, such as 3dlut_30 corresponding to 30 Hz and 30 Hz, 3dlut_90 corresponding to 90 Hz and 90 Hz... The gamma parameters corresponding to the reference refresh rate are stored in the read-only storage medium ROM of the DDIC. Take the target refresh rate as 90 Hz and the reference refresh rate as 120 Hz as an example. For example, when the refresh rate of the display screen is switched, the target refresh rate is obtained to be 90 Hz, and the 3D LUT corresponding to 90 Hz is loaded according to the target refresh rate of 90 Hz, that is, 3dlut_90, and then the display parameters under 90 Hz are converted into display parameters under 120 Hz according to 3dlut_90. Further, the gamma parameters in the DDIC end are obtained, wherein it should be noted that the gamma parameters are the gamma parameters corresponding to the reference refresh rate, that is, the gamma parameters corresponding to 120 Hz. The gamma parameters corresponding to 120 Hz are used to correct the display parameters under 120 Hz that have been converted from 90 Hz, that is, the gamma correction process is implemented.

[0088] In step S45, the display screen performs normal display with the adjusted display parameters.

[0089] In the present disclosure, the parameters required for display screen calibration are all pre-stored in the memory, so they can be used directly without recalculation, saving time. At the same time, the display method provided by the present disclosure uses color parameters to indirectly adjust the display parameters of the display screen, which not only maintains the original color of the display screen, but also compensates for the display brightness of the display screen, alleviating the display visual effect difference when switching between different refresh rates.

[0090] Based on the same concept, an embodiment of the present disclosure also provides a display device.

[0091] It is understandable that the display device provided by the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function in order to realize the above functions. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.
