[0048] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0049] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0050] In practical applications, electronic device displays typically show data based on a pre-set screen brightness. This data display method is not flexible enough.

[0051] To address the aforementioned technical issues, related technologies have provided solutions such as using an ambient light sensor (ALS) installed in an electronic device to collect ambient light brightness and adaptively adjusting the brightness of the display screen based on the ambient light brightness, thereby adjusting the display brightness of the data. Another solution involves using a color temperature sensor to collect the ambient light color temperature and then adaptively adjusting the display screen brightness based on that color temperature. However, in both of these solutions, adjusting the display screen brightness solely based on ambient light parameters cannot meet the actual data display needs of users.

[0052] To address the above issues, this application provides a display control method and apparatus. The display control method provided in this application can determine the display brightness at a second time (i.e., when the display device displays first data at a first moment) based on first information (i.e., the display brightness when the display device displays first data at a first moment), and control the display device to display the second data based on the second information. This achieves the determination of the display brightness of the data to be displayed based on the display brightness of historical data displayed on the display screen, thereby enabling smooth adjustment of the display brightness of the display screen according to changes in the data displayed on the screen. This reduces the probability of drastic changes in the display brightness of the screen, and thus improves the data display effect of the display screen.

[0053] The display control method provided in this application embodiment can be implemented by the processor of an electronic device.

[0054] It should be noted that the aforementioned processor can be at least one of the following: Application Specific Integrated Circuit (ASIC), Digital Signal Processor (DSP), Digital Signal Processing Device (DSPD), Programmable Logic Device (PLD), Field Programmable Gate Array (FPGA), Central Processing Unit (CPU), Controller, Microcontroller, and Microprocessor.

[0055] For example, electronic devices may include devices equipped with a display screen, such as televisions and mobile phones; for example, electronic devices may include devices with data output capabilities and the ability to establish a communication connection with the display screen, such as the host device of a computer.

[0056] Figure 1 This is a flowchart illustrating the display control method provided in an embodiment of this application, as shown below. Figure 1 As shown, the process may include steps 101 to 103:

[0057] Step 101: Obtain the first information.

[0058] The first information includes the display brightness when the display device displays the first data at the first moment.

[0059] In one implementation, the first data may include static display data, such as statically displayed text data and image data; for example, the first data may include dynamically displayed data, such as scrolling text data, video data, blinking controls, and time data.

[0060] In one embodiment, the display device may include a display screen; for example, the display screen may include a liquid crystal display (LCD) or an organic light-emitting display (OLED); for example, the display device may be integrated into an electronic device, such as a laptop computer or a mobile phone; for example, the display device may receive display data and control commands sent by the electronic device through its communication connection with the electronic device, and render display data based on the control commands.

[0061] For example, the first information can be obtained in real time by detecting the display brightness of the display device; or it can be determined based on the display brightness of the third data displayed at the third moment, that is, the first information can be predetermined; wherein, the third moment can include the moment before the first moment.

[0062] Step 102: Determine the second information based on the first information.

[0063] The second information includes the display brightness when the display device displays the second data at the second moment; the second moment includes at least the moment following the first moment.

[0064] In one implementation, the second moment may include a moment adjacent to the first moment. For example, during video playback, the first data may be the first frame of video data at the first moment, and the second data may be the second frame of video data at the next moment after the first moment. For example, the second moment may include a moment that is not adjacent to the first moment. For example, when the first data is displayed at the first moment, the display screen is in an active state, and for a period of time after the first moment, the display screen is in a dormant state. At the second moment, the display screen is reactivated. In this case, the second moment may not be adjacent to the first moment.

[0065] In one implementation, the type of the second data can be the same as the type of the first data, for example, both the first data and the second data are image data; for example, the type of the second data can be different from the type of the first data, for example, the first data is image data and the second data is text data.

[0066] For example, the second information can be determined in any of the following ways:

[0067] The first information is adjusted according to the first type and the second type to determine the second information; wherein the first type can be the type of the first data and the second type can be the type of the second data; for example, if the first type and the second type are the same, the first information is adjusted to a first degree; if the first type and the second type are different, the first information is adjusted to a second degree; wherein the first degree and the second degree are different.

[0068] The first information is adjusted based on a first quantity and a second quantity to determine the second information; wherein, the first quantity may include the data volume and / or resolution of the first data, and the second quantity may include the data volume and / or resolution of the second data; if the absolute value of the difference between the first quantity and the second quantity is less than or equal to a preset threshold, the first information is adjusted to a third degree; if the absolute value of the difference between the first quantity and the second quantity is greater than the preset threshold, the first information is adjusted to a fourth degree; wherein, the third degree and the fourth degree may be different.

[0069] The first information is adjusted based on the similarity between the first data and the second data to determine the second information; for example, if the first data and the second data are the same, the second information can be the same as the first information; if the first data and the second data are different, the first information can be adjusted to determine the second information.

[0070] Step 103: Based on the second information, control the display device to display the second data.

[0071] As can be seen from the above, the display control method provided in this application, after obtaining the display brightness (i.e., first information) of the display device when displaying first data at a first moment, can determine second information based on the first information and control the display device to display second data based on the second information; wherein, the second information includes the display brightness of the display device when displaying second data at a second moment; the second moment includes at least the moment after the first moment.

[0072] Therefore, the display control method provided in this application embodiment, when the first time is a historical time and the second time is the current time, can determine the current brightness of the display device when displaying the current data based on the historical brightness when the display device displays historical data, thereby realizing a smooth adjustment from historical brightness to current brightness, reducing the probability of drastic changes in the display brightness of the display screen, and improving the data display effect of the display screen.

[0073] Based on the foregoing embodiments, in the display control method provided in this application, the second information includes the display brightness of at least a portion of the area when the display device displays the second data.

[0074] In one embodiment, the second information may include the display brightness of a portion of the area when displaying the second data, such as a display area with a certain area centered on the midpoint of the display device, or a display area with a certain area including the corners of the display device; for example, at least a portion of the area may include the entire display area of ​​the display device.

[0075] For example, the second information can be determined based on data display requirements, user's personal usage habits, type of second data, resolution of second data, amount of second data, number of windows currently displayed in the display device, and window hierarchy relationship of at least one window displayed in the display device.

[0076] For example, at least a portion of the area can be determined based on the characteristics of the data contained in the second data. For instance, if the second data is image data and contains a user-defined target object, then at least a portion of the area can include the area where the target object is displayed. For example, if the target object is a mountain range, the display brightness of the pixel area in the second data that includes the mountain range can be adjusted, while the display brightness of the pixel area in the second data other than the pixel area of ​​the mountain range is kept at the default brightness. For example, the default brightness can include the first information and can also include the display brightness that is preset for the second data.

[0077] For example, it can be determined whether to adjust the overall display area of ​​the display device according to the type of the display device; for example, if the display device is an LCD, the second information may include the overall display area of ​​the display device; if the display device is an OLED, the second information may include a portion of the display area or the entire display area of ​​the display device.

[0078] For example, determining the second information based on the first information can be achieved through... Figure 2 The process shown is implemented as follows: Figure 2 This is a flowchart illustrating the process of determining the second information provided in an embodiment of this application, such as... Figure 2 As shown, the process may include steps 201 to 203:

[0079] Step 201: Obtain the first brightness and the second brightness.

[0080] The first brightness includes the brightness of at least a portion of the pixel region of the first data; the second brightness includes the brightness of at least a portion of the pixel region of the second data.

[0081] For example, the first brightness and the second brightness can be determined based on the data characteristics of the data contained in the first data and the second data. In other words, the first brightness and the second brightness can be determined before the display device displays the first data and the second data.

[0082] For example, given that both the first data and the second data include n pixels, the first brightness br A It can be obtained through equation (1):

[0083]

[0084] In equation (1), Let represent the brightness of the i-th pixel in the first data, which can be calculated using equation (2):

[0085]

[0086] In equation (1), i represents the number or number of pixels in the first data. This can represent the RGB value of the i-th pixel in the first data set; for example, when the value of i iterates from 1 to n, br A It can represent the overall brightness of the first data, and when i is a proper subset of [1, n], br A It can represent the brightness of a portion of the first data.

[0087] For example, the second brightness br B It can be obtained through equation (3):

[0088]

[0089] In equation (3), The brightness of the i-th pixel in the second data can be represented by equation (4):

[0090]

[0091] In equation (4), i represents the number or number of pixels in the second data. This can represent the RGB value of the i-th pixel in the second data; for example, when the value of i iterates from 1 to n, br B It can represent the overall brightness of the first data, and when i is a proper subset of [1, n], br B It can represent the brightness of a portion of the first data.

[0092] For example, different colors can have different brightness levels. In practical applications, the brightness levels of different colors can be as follows: Br(black-0,0,0)=0.000000; Br(indigo-0,0,255)=0.328424; Br(red-255,0,0)=0.547373; Br(violet-255,0,255)=0.622073; Br(green-0,255,0)=0.821060; Br(aqua-blue-0,255,255)=0.869083; Br(yellow-255,255,0)=0.959792; Br(white-255,255,255)=1.000000.

[0093] Step 202: Based on the first brightness and the second brightness, process the first information to obtain the third information.

[0094] For example, the degree of adjustment to the first information can be determined based on the trend of change between the first and second brightness, and the first information can be adjusted based on the degree of adjustment to obtain the third information; for example, if the second brightness shows an increasing trend relative to the first brightness, the first information can be strengthened to obtain the third information; if the second brightness shows a decreasing trend relative to the first brightness, the first information can be weakened to obtain the third information.

[0095] For example, the third information may include a weighted result obtained by weighting the second information.

[0096] Step 203: Process the third information to determine the second information.

[0097] For example, the second information can be implemented in any of the following ways:

[0098] The third piece of information is weighted, and the result of the weighting is determined as the second piece of information.

[0099] Based on the difference between the first brightness and the second brightness, a weighting coefficient is determined, and the third information is weighted according to the weighting coefficient. The weighted result is then determined as the second information.

[0100] As can be seen from the above, in the display control method provided in this application embodiment, after obtaining the first brightness and the second brightness, the first information can be processed based on the first brightness and the second brightness to obtain the third information, and the third information can be processed to determine the second information. The first brightness includes the brightness of at least a portion of the pixel area of ​​the first data; the second brightness includes the brightness of at least a portion of the pixel area of ​​the second data.

[0101] Therefore, since the first brightness and the second brightness can characterize the pixel features of the first data and the second data themselves, the process of processing the first information based on the first brightness and the second brightness to obtain the third information reflects the adjustment of the historical display brightness of the display screen according to the pixel features of the data displayed on the display screen itself. This makes the second information not only smoother than the first information, reducing the probability of sudden brightness changes in the display device displaying the second data, but also allows the second information to carry the brightness features of the second data, thereby enabling the second information to specifically improve the display effect of the second data.

[0102] Based on the foregoing embodiments, the display control method provided in this application, which processes the first information based on the first brightness and the second brightness to obtain the third information, can be implemented in the following way:

[0103] Determine the brightness difference between the first brightness and the second brightness; if the brightness difference is greater than or equal to a specified threshold, process the first information based on the first brightness and the second brightness to obtain the third information.

[0104] For example, if the difference in brightness is less than a specified threshold, the operation of processing the first information with the second brightness to obtain the third information can be skipped.

[0105] In one implementation, the specified threshold can be adjusted based on at least one of the following factors: the user's personal usage habits, the data display performance of the display device, the application scenario of the data displayed by the display device, the ambient light brightness, and the ambient light color temperature; for example, the specified threshold can also be manually set by the user.

[0106] In one implementation, the brightness difference can be represented by the absolute value of the difference between the first brightness and the second brightness; for example, the brightness difference can be represented by a matrix, which may include the brightness difference between n pixels in the first data and n pixels in the second data; for example, the brightness difference may include the overall brightness difference between the first data and the second data, that is, the brightness difference between n pixels in the first data and n pixels in the second data; for example, the brightness difference may include the brightness difference between a portion of the first data and a portion of the second data, such as the brightness difference between pixels k to k+m in the first data and pixels k to k+m in the second data, where k and m can be integers greater than or equal to 0, and k+m can be an integer greater than or equal to 0 and less than n.

[0107] As can be seen from the above, in the display control method provided in this application embodiment, when the brightness difference between the first brightness and the second brightness is determined, and the brightness difference is greater than or equal to a specified threshold, the first information is processed based on the first brightness and the second brightness to obtain the third information.

[0108] Therefore, the display control method provided in this application, when determining that the brightness difference between the first brightness and the second brightness is greater than or equal to a specified threshold, processes the first information based on the first brightness and the second brightness, thereby achieving strict control over the processing of the first information; and, when the brightness difference between the first brightness and the second brightness is greater than or equal to the specified threshold, processes the first information based on the first brightness and the second brightness, so that the processing of the first information and the third information obtained from processing the first information can fully compensate for the relatively obvious brightness difference between the first brightness and the second brightness, thereby further improving the display effect of the second data.

[0109] Based on the foregoing embodiments, the display control method provided in this application, which processes the first information based on the first brightness and the second brightness to obtain the third information, can also be implemented in the following ways:

[0110] Determine the brightness contrast information between the first brightness and the second brightness, and process the first information based on the brightness contrast information to obtain the third information.

[0111] For example, the brightness contrast information may include the brightness of all pixels in the first data and the contrast information between the brightness of all pixels in the second data; for example, the brightness contrast information may also include the brightness of a first set of pixels in the first data and the contrast information between the brightness of a second set of pixels in the second data, wherein the first set of pixels may correspond to the second set of pixels; for example, the pixel number corresponding to the first set of pixels and the pixel number corresponding to the second set of pixels may be the same, for example, the first set of pixels includes the kth to the (k+m)th pixels in the first data, while the second set of pixels may include the kth to the (k+m)th pixels in the second data; for example, the display area corresponding to the first set of pixels and the display area corresponding to the second set of pixels may be the same; for example, the display object corresponding to the first set of pixels and the real object corresponding to the second set of pixels may be the same.

[0112] For example, the first information can be weighted based on brightness contrast information to obtain the third information.

[0113] For example, the third piece of information x can be calculated using equation (5):

[0114]

[0115] Wherein, α can be the brightness of the display screen when displaying the first data, i.e., the first information, which is the default brightness of the display screen when displaying the second data before adjusting the display brightness of the second data; for example, α can be the display brightness preset in the electronic device, or it can be the display brightness determined according to the third data displayed at the third moment, i.e., the first information.

[0116] As can be seen from the above, in the display control method provided in this application embodiment, after determining the brightness contrast information between the first brightness and the second brightness, the first information can be processed based on the brightness contrast information to obtain the third information.

[0117] Therefore, since brightness contrast information can not only show the trend of change between the second brightness and the first brightness, but also reflect the amount of change between the second brightness and the first brightness, the third information obtained by processing the first information based on brightness contrast information can not only reflect the trend of change between the brightness of the first data and the brightness of the second data, but also cover the actual amount of change between the brightness of the second data and the brightness of the first data. This can improve the consistency between the third information and the data display changes when switching from the first data to the second data.

[0118] Based on the foregoing embodiments, the third information is obtained by processing the first information based on the brightness contrast information, which can be achieved through steps A1 to A3:

[0119] Step A1: Determine the brightness adjustment parameters.

[0120] In one implementation, the brightness adjustment parameter can represent a weighting coefficient used to adjust brightness contrast information. For example, the brightness adjustment parameter can change depending on the usage scenario of the display screen or electronic device. For example, there can be a one-to-one correspondence between the brightness adjustment parameter and the usage scenario. For instance, in an office scenario, the brightness adjustment parameter can be the first parameter, while in a home scenario, the brightness adjustment parameter can be the second parameter. For example, the brightness adjustment parameter can be related to the usage time of the display screen or electronic device. For instance, when the usage time is during office hours, the brightness adjustment parameter can be the third parameter, while when the usage time is during rest hours, the brightness adjustment parameter can be the fourth parameter.

[0121] Step A2: Adjust the brightness contrast information based on the brightness adjustment parameters to obtain the brightness adjustment result.

[0122] For example, the brightness adjustment results may include the results of enhancing or weakening brightness contrast information.

[0123] For example, an adjustment algorithm can be determined, and then the brightness contrast information can be adjusted based on the brightness adjustment parameters using the adjustment algorithm to obtain the brightness adjustment result; for example, the adjustment algorithm can correspond to the usage period and / or usage scenario of the display device or electronic device, and the embodiments of this application do not limit it in this regard.

[0124] For example, the environmental state of the display screen can be obtained, and the brightness contrast information can be adjusted based on the environmental state and brightness adjustment parameters to obtain the brightness adjustment result; for example, the environmental state may include ambient light brightness and / or ambient light color temperature, etc.

[0125] Step A3: Adjust the first information based on the brightness adjustment result to obtain the third information.

[0126] For example, if the brightness adjustment result indicates an enhancement of brightness contrast information, the first information can be enhanced based on the brightness adjustment result to obtain the third information; if the brightness adjustment result indicates a reduction of brightness contrast information, the first information can be reduced based on the brightness adjustment result to obtain the third information.

[0127] As can be seen from the above, in the display control method provided in this application embodiment, after determining the brightness adjustment parameter, the brightness contrast information is adjusted based on the brightness adjustment parameter to obtain the brightness adjustment result, and then the first information is adjusted based on the brightness adjustment result to obtain the third information.

[0128] Therefore, the display control method provided in this application adjusts the brightness contrast information based on the brightness adjustment parameters to obtain the brightness adjustment result. By adjusting the brightness adjustment parameters, flexible, diverse, and controllable adjustments to brightness contrast and even the first information can be achieved. When the brightness adjustment parameters are related to the actual display requirements, targeted, flexible, and adaptive adjustments to brightness contrast and even the first information can be achieved by adjusting the brightness adjustment parameters, thereby improving the display effect of the display device.

[0129] Based on the foregoing embodiments, the display control method provided in this application determines the brightness adjustment parameter through... Figure 3 The process shown is implemented as follows: Figure 3 This is a flowchart illustrating the process of determining brightness adjustment parameters provided in an embodiment of this application, as shown below. Figure 3 As shown, the process may include steps 301 to 304:

[0130] Step 301: In response to the adjustment operation on the first information, the initial brightness is obtained.

[0131] In one embodiment, the adjustment operation of the first information may include a user-triggered operation, such as a touch operation or swipe operation input by the user to the display device, or an adjustment operation input by the user to the peripheral control device of the electronic device; for example, the peripheral control device may include a mouse or keyboard, etc.

[0132] In one implementation, the adjustment operation of the first information may include an operation automatically triggered by the electronic device. For example, when the usage scenario or usage period of the electronic device or display screen changes, or when the environmental state changes, the adjustment operation of the first information may be automatically triggered.

[0133] In one implementation, the initial brightness may include a brightness that is increased, decreased, or maintained based on the first information, obtained after quantifying the adjustment operation.

[0134] Step 302: Obtain the initial brightness adjustment parameters.

[0135] In one embodiment, the initial brightness adjustment parameter may be stored in the electronic device; for example, the initial brightness adjustment parameters may be different for different models or types of display screens; for example, the initial brightness adjustment parameter may be adjusted according to at least one of the following: the size, manufacturing process, material, service life, power consumption, and operating mode of the display screen.

[0136] For example, the usage scenarios and / or usage periods of electronic devices or display screens can have a one-to-one correspondence with the initial brightness adjustment parameters, and this application embodiment does not limit this.

[0137] Step 303: Based on the first information and the initial brightness, determine the brightness adjustment step size.

[0138] For example, the brightness adjustment step size may include a brightness adjustment step size that gradually adjusts the initial brightness; for example, the brightness adjustment step size may include at least one brightness adjustment unit; wherein, the brightness adjustment unit may include the basic unit for brightness adjustment of an electronic device.

[0139] For example, the brightness adjustment step size can be determined in the following way:

[0140] Obtain the operation parameters for adjusting the brightness from the first information to the initial brightness, and determine the brightness adjustment step size based on the operation parameters; wherein, the operation parameters may include the number of times the adjustment operation from the first information to the initial brightness is executed; for example, the brightness adjustment step size determined based on the operation parameters may be the quotient of the brightness difference between the first information and the initial brightness and the number of executions.

[0141] Step 304: Determine the brightness adjustment parameters based on the brightness adjustment step size and the initial brightness adjustment parameters.

[0142] For example, the initial brightness adjustment parameter can be corrected based on the brightness adjustment step size, and the correction result can be determined as the brightness adjustment parameter.

[0143] As can be seen from the above, in the display control method provided in this application embodiment, in response to the adjustment operation of the first information, the initial brightness is obtained, and after obtaining the initial brightness adjustment parameter, the brightness adjustment parameter can be determined based on the first information and the initial brightness adjustment parameter.

[0144] Therefore, the display control method provided in this application incorporates the initial brightness obtained from the adjustment operation of the first information during the determination of the brightness adjustment parameters. This makes the brightness adjustment parameters dynamically adjustable and controllable, and makes the determination method of the brightness adjustment parameters more flexible and controllable. Furthermore, the brightness adjustment parameters are determined by the brightness adjustment step size determined based on the first information and the initial brightness, as well as the initial brightness adjustment parameters. This means that the adjustment process of the brightness adjustment parameters not only includes the factors of the adjustment operation, but also includes the historical brightness information of the display device, thereby making the brightness adjustment parameters more consistent with the actual data display state of the display device.

[0145] Based on the foregoing embodiments, the display control method provided in this application, which determines the brightness adjustment step size based on the first information and the initial brightness, can be implemented in the following way:

[0146] If the first or second condition is met, the brightness adjustment step size is determined to be the first step size.

[0147] The first condition includes a first brightness less than a second brightness and a first information less than an initial brightness; the second condition includes a first brightness greater than a second brightness and a first information greater than an initial brightness.

[0148] For example, if neither the first condition nor the second condition is met, it can be determined that the brightness adjustment step size is not the first step size.

[0149] For example, the brightness adjustment step size can also be determined based on the first information and the initial brightness in the following ways:

[0150] If the third or fourth condition is met, the brightness adjustment step size is determined to be the second step size.

[0151] The third condition includes a first brightness less than a second brightness and a first information greater than an initial brightness; the fourth condition includes a first brightness greater than a second brightness and a first information less than an initial brightness.

[0152] For example, if the third and fourth conditions are not met, it can be determined that the brightness adjustment step size is not the second step size.

[0153] In one implementation, adjusting the first information to be less than the initial brightness may include an operation to increase the brightness; adjusting the first information to be greater than the initial brightness may include an operation to decrease the brightness.

[0154] For example, the first step length and the second step length can be different.

[0155] For example, in br A <br B And the adjustment operation is changed to increase brightness, or br A >br B Furthermore, when the adjustment operation is a brightness reduction operation, the brightness adjustment step size, i.e., the first step size, can be δ; for example, under the condition that the initial brightness adjustment parameter is γ0, and the brightness adjustment parameter is denoted as γ, γ can be calculated using general formula (6):

[0156] γ=γ0+l*δ (6)

[0157] Where l can be an integer greater than or equal to 1, used to represent the number of times the initial brightness adjustment parameter γ0 is adjusted.

[0158] For example, in br A <br B And the adjustment operation is set to brightness reduction, or br A >br B Furthermore, when the adjustment operation is a brightness increase operation, the brightness adjustment step size, i.e., the first step size, can be -δ; for example, under the condition that the initial brightness adjustment parameter is γ0, and the brightness adjustment parameter is denoted as γ, γ can be calculated using general formula (7):

[0159] γ=γ0-l*δ (7)

[0160] For example, if the first, second, third, and fourth conditions are not met, the brightness adjustment step size can be determined to be 0, that is, the initial brightness adjustment parameter can be determined as the brightness adjustment parameter.

[0161] As can be seen from the above, in the display control method provided in this application embodiment, if the first condition or the second condition is met, the brightness adjustment step size is determined to be the first step size; if the third condition or the fourth condition is met, the brightness adjustment step size is determined to be the second step size. The first condition includes the first brightness being less than the second brightness and the first information being less than the initial brightness; the second condition includes the first brightness being greater than the second brightness and the first information being greater than the initial brightness; the third condition includes the first brightness being less than the second brightness and the first information being greater than the initial brightness; and the fourth condition includes the first brightness being greater than the second brightness and the first information being less than the initial brightness.

[0162] Therefore, the display control method provided in this application embodiment can flexibly determine the brightness adjustment step size under various conditions based on the relationship between the first brightness, the second brightness, the first information, and the initial brightness, thereby obtaining diverse brightness adjustment step sizes that can meet the actual display adjustment needs of the display screen. Furthermore, in the process of determining the brightness adjustment step size, the first brightness, the second brightness, the first information, and the initial brightness are fully considered, so that the brightness adjustment step size not only includes the characteristic information of the display data, but also includes the brightness adjustment information of the display screen, thereby improving the accuracy of the brightness adjustment step size.

[0163] Based on the foregoing embodiments, the display control method provided in this application, which processes the third information to determine the second information, can be implemented in the following ways:

[0164] Determine the luminous flux parameters; process the third information based on the luminous flux parameters to determine the second information.

[0165] The luminous flux parameter includes a luminous flux comparison parameter when the display device switches from displaying the first data to displaying the second data.

[0166] Luminous flux refers to the derived quantity of radiant flux evaluated according to internationally standardized human visual characteristics. It is equal to the product of the radiant energy of a certain wavelength band per unit time and the relative visibility of that wavelength band. The unit of luminous flux is lm (lumen). Luminous intensity represents the luminous flux emitted by a light source per unit solid angle per unit surface area projected onto a plane perpendicular to its light transmission direction, and its unit is candela per square meter (cd / m²). 2 A solid angle, also known as a nit, represents the angle of an object in three-dimensional space relative to a specific point. It is an analogy of a plane angle in three-dimensional space.

[0167] For example, assuming the display area of ​​the display device is S and there are n pixels in the display device, then the luminous flux of the display device is equal to the sum of the luminous flux of each pixel. And according to the relationship between luminous flux and brightness, the luminous flux φ of the display device is equal to the sum of the products of the brightness of each pixel, the surface area, and the solid angle, as shown in equation (8):

[0168] φ = φ1 + φ2 + ... + φ n = (L1+L2+…+L n )ΩS (8)

[0169] Among them, φ1, φ2, ..., and φ n L1, L2, ..., and L2 are the luminous flux of the first, second, ..., and nth pixels of the display device, respectively; L1, L2, ..., and L2 are the luminous intensity of the first, second, ..., and nth pixels, respectively.

[0170] For example, the luminous flux parameter may include the difference between the luminous flux when the display device displays the first data with the first information and the luminous flux when the display device displays the second data with the default brightness; for example, the luminous flux parameter may include the ratio between the luminous flux when the display device displays the first data with the first information and the luminous flux when the display device displays the second data with the default brightness; for example, the default brightness may include a preset display brightness of the display device; for example, the default brightness may be different from the first information or may be the first information.

[0171] For example, the third information can be weighted based on the light flux parameter to determine the second information.

[0172] As can be seen from the above, in the display control method provided in this application embodiment, after determining the luminous flux, the third information can be processed based on the luminous flux parameter to determine the second information; wherein, the luminous flux parameter includes the luminous flux comparison parameter when the display device switches from displaying the first data to displaying the second data.

[0173] Therefore, the display control method provided in this application takes into account the luminous flux of the display device when displaying the first data and the second data when determining the second information. This makes the second information include not only static factors such as the display performance of the display device, but also dynamic factors such as the display device displaying the first data and the second data. This allows the second information to effectively improve the display effect of the second data within the performance parameter range of the display device.

[0174] Based on the foregoing embodiments, the luminous flux parameter in the display control method provided in this application can be determined in the following ways:

[0175] Obtain the first luminous flux; determine the second luminous flux based on the first information; determine the luminous flux parameters based on the first luminous flux and the second luminous flux.

[0176] The second luminous flux includes the luminous flux when the display device displays the second data based on the first information.

[0177] For example, the first luminous flux may include the luminous flux when the display device displays the first data with the first information. For example, the first luminous flux and the second luminous flux may include the luminous flux of at least a portion of the area when the display device displays the first data and the second data with the first information, respectively.

[0178] In one embodiment, the luminous flux parameter may include the ratio between a first luminous flux and a second luminous flux; for example, the first luminous flux φ A and the second luminous flux φ B The results can be obtained by equations (9) to (10) respectively:

[0179] φ A =φ A1 +φ A2 +…+φ An =(L A1 +L A2 +…+L An )ΩS (9)

[0180] φ B =φ B1 +φ B2 +…+φ Bn =(L B1 +L B2 +…+L Bn )ΩS (10)

[0181] Where S is the area of ​​the display screen of the display device; φ A1 φ A2 ... and φ An Used to represent the luminous flux of the first, second, ..., and nth pixels of the first data; L A1 L A2 ... and L An Used to represent the brightness of the first, second, ..., and nth pixels of the first data; Ω is the solid angle; φ B1 φ B2 ... and φ Bn These represent the luminous flux of the first, second, ..., and nth pixels of the second data; L B1 L B2 ... and L Bn Used to represent the brightness of the first, second, ..., and nth pixels of the second data.

[0182] For example, the luminous flux parameter may include the ratio between the first luminous flux and the second luminous flux; for example, according to equations (9) to (10), the luminous flux parameter y can be expressed by equation (11):

[0183]

[0184] For example, in order to reduce the brightness jump of the display device when switching from displaying the first data to displaying the second data, and to make the overall brightness output of the display device as smooth as possible, considering the differences in brightness display corresponding to different color brightness, the color brightness can be normalized based on the first luminous flux and the target luminous flux, and the result of normalizing the color brightness based on the first luminous flux and the target luminous flux can be the same, as shown in equation (12):

[0185]

[0186] Where, φ B 'The target luminous flux is the amount of light emitted when the display device displays the second data, and the target luminous flux is an unknown quantity related to the second luminous flux; for example, the target luminous flux φ B 'It can be obtained by assuming the target brightness β, i.e., the second information, the first information, and the second luminous flux, as shown in equation (13):

[0187]

[0188] Therefore, according to equation (13), equation (12) can be transformed into equation (14):

[0189]

[0190] For example, by adding the brightness adjustment parameter γ, equation (14) can be further transformed into equation (15):

[0191]

[0192] In other words, when the display device switches from displaying the first data to displaying the second data, by adjusting the display brightness of the display device to the second information β, the brightness of the i-th pixel in the second data is uniformly adjusted to the original brightness of the second data.

[0193] For example, when all pixels of the first data and the second data are black, the display brightness of the display device can be left unchanged, that is, the first information remains unchanged.

[0194] For example, for OLED, the display brightness of each pixel can be controlled individually; for LCD, since its backlight brightness can be obtained, the brightness of each pixel can be obtained based on the brightness of the smallest RGB unit after filtering, which is obtained by testing at the factory.

[0195] In the above embodiments, color brightness, also known as color luminance, is one of the three elements of color. In practical applications, different colors will have differences in brightness, and the same color will also have variations in brightness. For example, when the brightness of the displayed data is low, such as black or indigo, appropriately reducing the display brightness will have a slight impact on the display effect of the display device; while when the brightness of the displayed content is high, such as white or yellow, reducing the display brightness will have a more significant impact on the display effect of the display device.

[0196] As can be seen from the above, in the display control method provided in the embodiments of this application, after obtaining the first luminous flux and the second luminous flux, the luminous flux parameter can be determined based on the first luminous flux and the second luminous flux. Furthermore, the first luminous flux includes the luminous flux when the display device displays the first data, and the second luminous flux includes the luminous flux when the display device displays the second data with the first information.

[0197] Therefore, the display control method provided in this application embodiment can reflect the difference in luminous flux when the display device displays the first data and the second data. Furthermore, since the second luminous flux is the luminous flux when the display device displays the second data based on the first information, the luminous flux parameter can contain the historical brightness information of the display device, thereby enabling the luminous flux parameter to more accurately reflect the historical data display status of the display device.
