[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0034] During image acquisition, because the human eye's perception of brightness and physical power have a non-linear relationship, if the received light signal is directly stored in a linear relationship of 0 to 255 (0 for black, 255 for white), for example, the value of white with a brightness of 20% is 255 × 0.2 = 51. This results in the human eye perceiving a mid-gray level of 51, leading to 205 levels in bright areas and only 50 levels in dark areas. To address the waste of bright area levels and low resolution in dark areas, gamma encoding is typically used to enhance the perceived mid-gray level, making the level distribution more uniform in both bright and dark areas, thus improving image resolution. In other words, gamma encoding redistributes grayscale to a state familiar to the eye, achieving efficient grayscale storage. When displaying the image on a screen, gamma decoding is required to adjust the image brightness (i.e., the conversion is reversed and transmitted through an inverse non-linear transformation).

[0035] A complete image processing process includes three stages: image acquisition, storage and transmission, and display output. Gamma correction can be performed at any of these stages. The following illustration further illustrates this process. Taking a camera as an example in the image acquisition stage, since the sensor is a linear element, the raw data captured is linear; that is, the RAW file contains linear data. Therefore, gamma correction (i.e., gamma correction during the gamma encoding process) needs to be performed during the conversion to IPG / JPEG, transforming the data into... Figure 1a The nonlinear curve shown. Figure 1a This is a schematic diagram of the first-stage curve of the correction process according to an exemplary embodiment, such as... Figure 1aAs shown, this non-linear curve takes the original scene brightness as input and outputs the file-entered value after gamma correction. It should be noted that gamma correction is generally not performed during the storage and transmission stage. Furthermore, in the display output stage, taking image viewing as an example, display gamma is typically used for gamma correction (i.e., gamma correction during the gamma decoding process), and the non-linear curve is as follows... Figure 1b As shown. Figure 1b This is a schematic diagram of the second-stage curve of the correction process according to an exemplary embodiment, as shown below. Figure 1b As shown, the nonlinear curve is related to... Figure 1a On the contrary, that is, equivalent to... Figure 1a The nonlinear transformation produces the opposite output, using Figure 1a The converted file input values ​​are used as input to obtain the corrected display brightness output, thereby enabling the gamma correction at each stage to generate a final gamma of 1. The correction result is as follows: Figure 1c As shown. Figure 1c This is a schematic diagram illustrating a correction result curve according to an exemplary embodiment. For example... Figure 1c As shown, Figure 1a and Figure 1b The combination of inputting the original scene brightness and outputting the displayed brightness ensures that the input and output images remain consistent throughout the entire correction process.

[0036] This calibration 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 leaves the factory, it is necessary to configure the corresponding gamma parameters for different refresh rates so that the display can obtain the corresponding gamma parameters to correct the display brightness at different refresh rates when switching refresh rates.

[0037] In related technologies, gamma correction is performed by matching the corresponding gamma parameters to different refresh rates, so that the human eye cannot perceive the visual effects caused by 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, since gamma correction can only adjust the grayscale values ​​(i.e., brightness) of each color on the display, this method can only alleviate the screen brightness difference problem caused by refresh rate switching, but cannot alleviate the screen color shift problem caused by refresh rate switching.

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

[0039] In the various embodiments of this disclosure, the display effect of the display screen can be a visual effect that the human eye can perceive, such as display color, display brightness, and display color temperature. This disclosure does not limit this aspect.

[0040] In the various embodiments of this disclosure, for ease of understanding, the gamma parameter can be used to replace the color parameter.

[0041] Figure 2 This is a flowchart illustrating a display method according to an exemplary embodiment, such as... Figure 2 As shown, the display method is applied to the terminal and includes the following steps.

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

[0043] In this embodiment of the disclosure, the target refresh rate is obtained when the terminal detects that the system needs to load a display effect at a certain refresh rate, or when the terminal detects that the system sends a refresh rate switching command.

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

[0045] In the embodiments of this disclosure, the first display parameter is a parameter that may cause changes in the display effect of the display screen. For example, it may be one or more parameter values ​​such as the RGB value of the image, color balance value, brightness value, etc. This disclosure does not limit it.

[0046] In this embodiment of the disclosure, the method of obtaining the first display parameter at the target refresh rate is not limited. For example, the terminal can obtain the first display parameter at the target refresh rate locally or from the network.

[0047] In step S13, the second display parameters are obtained based on the first display parameters and the preset color parameters.

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

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

[0050] In one embodiment, the reference refresh rate can be a fixed refresh rate selected at the factory or a pre-set fixed refresh rate. The gamma parameter is the gamma parameter configured in the display's memory based on the reference refresh rate at the factory. For example, when the display is manufactured with a fixed refresh rate of 120Hz, the gamma parameter corresponding to 120Hz is configured based on the display visual effect at 120Hz and stored in memory for later direct retrieval.

[0051] It should be noted that screen refresh rates are generally divided into 60Hz and 120Hz, with 120Hz and above considered high refresh rates. A 120Hz screen can display a higher number of frames per unit time, resulting in smoother visuals, less susceptibility to display distortion, and excellent responsiveness and fluidity, making it suitable for various scenarios. Therefore, 120Hz is generally chosen as the baseline refresh rate. Furthermore, in the display driver integrated circuit (DDIC) registers, only the gamma parameter corresponding to the baseline refresh rate needs to be configured. Since a set of gamma parameters occupies a large amount of memory, some DDICs only support storing 2-3 gamma parameters corresponding to different refresh rates. Therefore, the solution disclosed in this publication only requires configuring the gamma parameter corresponding to the baseline refresh rate, effectively saving memory space.

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

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

[0054] In this embodiment of the disclosure, the order of execution steps S11 and S12 is not limited. Step S11 can be executed first, followed by step S12, or step S12 can be executed first, followed by step S11, or steps S11 and S12 can be executed simultaneously.

[0055] The display method provided in this disclosure improves the display effect and enhances the user experience by directly obtaining the gamma parameter stored in the memory and adjusting the display parameters of the display screen.

[0056] In this embodiment of the disclosure, the implementation process of obtaining the second display parameter based on the first display parameter and the preset color will be described in detail below.

[0057] Figure 3This is a flowchart illustrating a method for adjusting color parameters according to an exemplary embodiment, such as... Figure 3 As shown, it includes the following steps.

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

[0059] In this embodiment of the disclosure, the third display parameter is the display parameter under the reference refresh rate corresponding to the first display parameter. The reference refresh rate is the preset refresh rate mentioned above. The first correspondence is the relationship between the display parameter under the target refresh rate and the display parameter under the reference refresh rate.

[0060] In this embodiment, color temperature compensation is primarily performed on the first display parameter based on a first correspondence. However, other color compensation methods can also be applied to the first display parameter based on the first correspondence, thereby ensuring that the display visual effects at different refresh rates can share the same gamma parameter corresponding to the base refresh rate. Therefore, the color temperature compensation in this embodiment is not a further limitation.

[0061] It should be noted that different target refresh rates correspond to different primary relationships, that is, different target refresh rates correspond to different display parameters under different target refresh rates and display parameters under different base refresh rates.

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

[0063] In this embodiment of the disclosure, the brightness compensation of the third display parameter is mainly based on the color parameter to perform gamma correction on the third display parameter in order to obtain the second display parameter.

[0064] In this embodiment, by adjusting the display parameters at the target refresh rate to match those at the reference refresh rate based on the relationship between the display parameters at the target refresh rate and those at the reference refresh rate, the display parameters at the target refresh rate are corrected, thereby making the display visual effect at the target refresh rate close to that at the reference refresh rate. This allows subsequent gamma correction to be performed directly using the gamma parameter corresponding to the reference refresh rate.

[0065] In this embodiment, by using indirect adjustment, the same gamma parameter corresponding to the same reference refresh rate can be used for calibration. Therefore, only one set of gamma parameters needs to be stored in the memory, saving storage space. Furthermore, this process replaces the previous method of using gamma parameters corresponding to different refresh rates for calibration. It eliminates the need to match different gamma parameters for different refresh rates, instead directly using data pre-stored in memory for calibration, saving both computational steps and display calibration time.

[0066] In this embodiment of the disclosure, it is necessary to obtain a first correspondence under the target refresh rate. Furthermore, this first correspondence can be obtained based on a lookup table. The following describes another method for adjusting based on color parameters.

[0067] Figure 4 This is a flowchart illustrating another method for adjusting color parameters according to an exemplary embodiment, such as... Figure 4 As shown, it includes the following steps.

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

[0069] The lookup table is used to characterize the relationship between the display parameters at the target refresh rate and the display parameters at the base refresh rate. In this embodiment, the system configures different lookup tables for different refresh rates, so different target refresh rates correspond to different first correspondences.

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

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

[0072] Steps S32 and S33 have been described in one embodiment of the method for adjusting based on color parameters, and therefore will not be repeated here.

[0073] It should be noted that although the embodiments of this disclosure use a lookup table to establish the relationship between the display parameters at the target refresh rate and the display parameters at the reference refresh rate, it is not limited to a lookup table. For example, the relationship between the display parameters at the target refresh rate and the display parameters at the reference refresh rate can also be a functional relationship established using a model, or a relationship established in other ways, which are not specifically limited in this disclosure.

[0074] In one embodiment, a lookup table built using a 3DLUT model is used as an example. It should be noted that a LUT (Look-Up Table) is essentially a lookup table; that is, given an input color value, the corresponding color value is found in the lookup table and output. LUTs are further divided into 1DLUTs and 3DLUTs. A 1DLUT means that the R, G, and B channel values ​​do not affect each other and are mapped independently. A 3DLUT, on the other hand, is composed of three 1DLUTs. The input RGB channel color values ​​are mapped according to three lookup tables in the 3DLUT to obtain the converted color. For example, R, G, and B can be used as the original color channel values, and r, g, and b can be used as the converted color channel values. This can be understood as a 1DLUT containing three mapping relationships: f1(R) = r, f2(G) = g, and f3(B) = b. 3DLUT, on the other hand, has a mapping relationship f(R, G, B) = (r, g, b). In 3DLUT, changing any one color channel value will affect the values ​​of all three color channels. That is, changing any color channel value will cause the other color channel values ​​to change accordingly.

[0075] 1DLUT can only control gamma, RGB balance (grayscale), and whitepoint, while 3DLUT can affect hue, saturation, and brightness through full-space color control. In other words, 3DLUT can affect color values, while 1DLUT can only affect brightness values. Therefore, 3DLUT is often used for precise color calibration. This disclosure uses the 3DLUT model to convert display parameters at different refresh rates into display parameters at a reference refresh rate, thereby achieving precise calibration of the display parameters.

[0076] This disclosure describes the implementation process of converting display parameters at different refresh rates into display parameters at a reference refresh rate using the 3DLUT model.

[0077] In the display screen calibration process, a 3DLUT model is used to establish the relationship between display parameters at different refresh rates and display parameters at a reference refresh rate, i.e., a 3DLUT lookup table, which is stored in the corresponding 3DLUT file. This establishment process includes: dividing the source RGB color space into a grid according to a certain sampling interval; 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) based on a cube interpolation algorithm; and placing the data from the source color space and the target color space into the table in order to form a 3DLUT lookup table, which is stored in a corresponding 3DLUT file in memory. Different refresh rates correspond to different 3DLUT files.

[0078] In this embodiment of the disclosure, the relationship between the display parameters at the target refresh rate and the display parameters at the reference refresh rate is established using the 3DLUT model in order to achieve accurate color compensation.

[0079] For ease of understanding, the implementation process of the above display method will be comprehensively explained below.

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

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

[0082] In this embodiment of the disclosure, a fixed refresh rate is selected as the base refresh rate when the display is manufactured, and the gamma parameter corresponding to the base refresh rate, i.e., the preset color parameter, is configured. The display effect under this base refresh rate is used as the standard display effect to correct the display effect of the display.

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

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

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

[0086] In this embodiment, a 3DLUT file corresponding to the target refresh rate is determined based on the target refresh rate. This 3DLUT file contains a 3DLUT lookup table for the target refresh rate, which includes the relationship between display parameters at the target refresh rate and display parameters at a reference refresh rate. Then, based on different parameters of the image at the target refresh rate, the corresponding parameters at the reference refresh rate are looked up in the 3DLUT lookup table and converted accordingly. This conversion process adjusts the display parameters of the screen. Further, a gamma parameter pre-stored in memory is obtained, i.e., the gamma parameter for determining the reference refresh rate, and gamma correction is performed based on this gamma parameter. This correction process further adjusts the display parameters of the screen. It should be noted that before gamma correction, the display parameters at the target refresh rate have already been adjusted based on the relationship between the display parameters at the target refresh rate and the display parameters at the reference refresh rate. This means that the display effect of the screen is already matched to the reference refresh rate, so the gamma parameter at the reference refresh rate can be used directly for correction without needing to match the gamma parameter of the target refresh rate.

[0087] To facilitate understanding, the following examples are illustrated with diagrams. Figure 6 This is a schematic diagram illustrating the determination of the gamma parameter based on the target refresh rate, according to an exemplary embodiment. Figure 6 As shown, the Application Processor (AP) stores different refresh rates and their corresponding 3DLUTs, such as storing 30Hz and its corresponding 3DLUT_30, 90Hz and its corresponding 3DLUT_90, and so on. The DDIC's read-only storage medium ROM stores the gamma parameter corresponding to the base refresh rate. Taking a target refresh rate of 90Hz and a base refresh rate of 120Hz as an example: When the display refresh rate changes, the target refresh rate is obtained as 90Hz. Based on the target refresh rate of 90Hz, the 3DLUT corresponding to 90Hz, i.e., 3DLUT_90, is loaded. Then, based on 3DLUT_90, the display parameters at 90Hz are converted to the display parameters at 120Hz. Further, the gamma parameter in the DDIC is obtained. It should be noted that the gamma parameter is the gamma parameter corresponding to the base refresh rate, i.e., the gamma parameter corresponding to 120Hz. The gamma correction process is achieved by using the gamma parameter corresponding to 120Hz to correct the display parameters that have been converted from 90Hz to 120Hz.

[0088] In step S45, the display screen displays normally with the adjusted display parameters.

[0089] In this disclosure, the parameters required for display calibration are all pre-stored in the memory, so they can be used directly without recalculation, saving time. Furthermore, the display method provided in this disclosure uses color parameters to indirectly adjust the display parameters, not only maintaining the original colors of the display but also compensating for the display brightness, thus mitigating visual differences when switching between different refresh rates.

[0090] Based on the same concept, embodiments of this disclosure also provide a display device.

[0091] It is understood that the display device provided in this disclosure includes hardware structures and / or software modules corresponding to each function in order to achieve the above-mentioned functions. In conjunction with the units and algorithm steps of the various examples disclosed in this disclosure, this disclosure can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed by hardware or by 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 beyond the scope of the technical solutions of this disclosure.
