[0042] Fifthly, embodiments of this application also provide a computer program product, which includes a computer program that, when executed by a processor, implements the steps of the method in any of the embodiments of the first aspect described above.

[0043] The display brightness adjustment method, apparatus, and computer equipment provided in this application include: obtaining first input signal values ​​at multiple adjustable grayscale binding points based on first display brightness values ​​of the display panel to be adjusted at multiple adjustable grayscale binding points acquired by an optical acquisition device on a production line; determining model curves of the display panel to be adjusted at multiple non-adjustable grayscale binding points based on each first input signal value; assigning input signal values ​​to each non-adjustable grayscale binding point based on each first input signal value, the model curves corresponding to each non-adjustable grayscale binding point, the first grayscale values ​​of the display panel to be adjusted at each adjustable grayscale binding point, and the second grayscale values ​​of the display panel to be adjusted at each non-adjustable grayscale binding point to obtain second input signal values ​​of the display panel to be adjusted at each non-adjustable grayscale binding point; and adjusting the display brightness of the display panel to be adjusted based on each first input signal value and each second input signal value. Here, adjustable grayscale binding points represent grayscale binding points where the display brightness value is lower than the upper limit of the brightness acquisition of the optical acquisition device, and non-adjustable grayscale binding points represent grayscale binding points where the display brightness value exceeds the upper limit of the brightness acquisition of the optical acquisition device. The above method can determine the model curves of the display panel at multiple grayscale binding points (i.e., non-adjustable grayscale binding points) where the display brightness value is lower than the upper limit of the brightness acquisition of the optical acquisition device, based on the first input signal value (i.e., the source value) of the display panel at the grayscale binding point where the display brightness value is lower than the upper limit of the brightness acquisition of the optical acquisition device. Then, based on the model curves corresponding to each non-adjustable grayscale binding point, the input signal values ​​of the display panel at each non-adjustable grayscale binding point can be assigned. This process can obtain the input signal values ​​of the display panel at each non-adjustable grayscale binding point without an optical acquisition device. Furthermore, based on multiple non-adjustable grayscale binding points... Adjusting the input signal value under grayscale binding points and multiple adjustable grayscale binding points to adjust the display brightness of the display panel can increase the display brightness range of the configured display panel. This allows the display panel to increase its peak brightness during use, meeting the display brightness configuration requirements. Consequently, the electronic device to which the display panel belongs can meet market demands, improve the applicability of the electronic device, and increase the product yield at the factory. At the same time, the above method does not require manual intervention, which not only reduces the accuracy of display brightness adjustment but also improves the speed and efficiency of display brightness adjustment.

[0058] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0059] In the display field, the requirements for display brightness in electronic devices are becoming increasingly stringent. For example, when viewing the output image of an electronic device's display panel in bright sunlight, the peak brightness of the display panel needs to be increased to enhance the clarity of the output image. Among other things, such as... Figure 1 Image (a) shows the output screen before the peak brightness of the display panel is increased, as shown in Figure (a). Figure 1 Image (b) shows the output image after the peak brightness of the display panel is increased. Therefore, configuring the display brightness of the display panel is crucial during the manufacturing process of electronic devices. In practical applications, optical acquisition devices are mainly used on the production line to collect the display brightness of the display panel, and the display brightness is configured based on the collected actual brightness. However, after long-term research, the inventors discovered that in related technologies, optical acquisition devices on the production line have limited brightness acquisition capabilities when collecting the display brightness of the display panel, resulting in the inability to meet the display brightness adjustment requirements. Based on this, this application provides a display brightness adjustment method that can adjust the display brightness of electronic devices produced on the production line to ensure that the display brightness of the electronic devices after leaving the factory meets market demands.

[0060] The display brightness adjustment method provided in this application embodiment can be applied to, for example, Figure 2 The display brightness adjustment system shown includes a computer device and an optical acquisition device on the production line. The optical acquisition device and the computer device are connected via communication, which can be through Wi-Fi, mobile network, or Bluetooth. The computer device can be, but is not limited to, a personal computer, desktop computer, laptop computer, iPad, smartphone, smart TV, or smart bracelet. The optical acquisition device can be a desktop optical measuring instrument, portable optical measuring instrument, etc. This embodiment does not limit the specific form of the computer device and the optical acquisition device. Figure 2 This illustration demonstrates a display brightness adjustment system using a personal computer as an example. The following embodiments will specifically describe the process of the display brightness adjustment method, using a computer device as the executing entity.

[0061] like Figure 3 The diagram shown is a flowchart illustrating a display brightness adjustment method provided in an embodiment of this application. This method may include the following steps:

[0062] S100: Based on the first display brightness value of the display panel to be adjusted under multiple adjustable grayscale binding points acquired by the optical acquisition equipment on the production line, obtain the first input signal value under multiple adjustable grayscale binding points. Wherein, adjustable grayscale binding points refer to grayscale binding points where the display brightness value is lower than the brightness acquisition upper limit of the optical acquisition equipment.

[0063] In practical applications, the grayscale binding points of the display panel to be adjusted can be understood as the grayscale values ​​corresponding to a specific display brightness value during the gamma adjustment process of the display panel to be adjusted. In this embodiment, grayscale binding points whose display brightness values ​​are lower than the brightness acquisition limit of the optical acquisition device can be called adjustable grayscale binding points, that is, the display brightness values ​​of the display panel to be adjusted at these grayscale binding points can be directly acquired by the optical acquisition device; and adjustable grayscale binding points can be called low grayscale binding points. Optionally, the brightness acquisition limit of the optical acquisition device can be 2800 nit, 2850 nit, 2900 nit, 2950 nit, or 3050 nit, etc., but in this embodiment, the brightness acquisition limit of the optical acquisition device is 3000 nit for example.

[0064] The aforementioned display panel to be adjusted may be, but is not limited to, an organic light-emitting diode (OLED) display panel, a cathode ray tube (CRT) display panel, or a light-emitting diode (LED) display panel. However, in this embodiment, the display panel to be adjusted is described as an active-matrix organic light-emitting diode (OLED) display panel.

[0065] Specifically, the computer equipment can pre-train an algorithm model, and then input the first display brightness values ​​of the display panel to be adjusted under multiple adjustable grayscale binding points, which are collected by the optical acquisition equipment on the production line, into the algorithm model in sequence. The algorithm model outputs the first input signal values ​​of the display panel to be adjusted under each adjustable grayscale binding point.

[0066] In addition, for any adjustable grayscale binding point, the computer equipment can perform conversion, transformation, and filtering operations on the first display brightness value of the display panel to be adjusted under the adjustable grayscale binding point, which is acquired by the optical acquisition equipment on the production line, and determine the first input signal value of the display panel to be adjusted under the adjustable grayscale binding point, i.e., the first source value, based on the operation results.

[0067] It should be noted that when the optical acquisition equipment on the production line acquires the first display brightness value of the display panel to be adjusted, the optical acquisition equipment can contact the display panel to be adjusted. This contact method can be that the optical acquisition equipment is in perpendicular contact with the display panel to be adjusted, or it can be that the optical acquisition equipment is in tilted contact with the display panel to be adjusted.

[0068] S200. Based on each first input signal value, determine the model curve of the display panel to be adjusted under multiple non-adjustable grayscale binding points. Among them, non-adjustable grayscale binding points refer to grayscale binding points where the display brightness value exceeds the brightness acquisition limit of the optical acquisition device.

[0069] In this embodiment of the application, grayscale binding points whose display brightness values ​​exceed the upper limit of the brightness acquisition of the optical acquisition device can be called non-adjustable grayscale binding points, that is, the display brightness values ​​of the display panel to be adjusted under such grayscale binding points cannot be directly acquired by the optical acquisition device; and non-adjustable grayscale binding points can be called high grayscale binding points.

[0070] In one implementation, a computer device can pre-train a model for constructing a high grayscale model curve, and then input at least one of the first input signal values ​​into the model. The model outputs a model curve of the display panel to be adjusted under multiple non-adjustable grayscale binding points. Optionally, the aforementioned model can be implemented by at least one of a convolutional neural network model, a fully connected neural network model, a long short-term memory neural network model, a recurrent recurrent neural network model, etc.

[0071] In another implementation, the computer device can perform fitting processing based on at least one of the first input signal values ​​to obtain the model curve of the display panel to be adjusted under multiple non-adjustable grayscale binding points.

[0072] S300: Based on each first input signal value, the model curve corresponding to each non-adjustable grayscale binding point, the first grayscale value of the display panel to be adjusted under each adjustable grayscale binding point, and the second grayscale value of the display panel to be adjusted under each non-adjustable grayscale binding point, the input signal value is assigned to each non-adjustable grayscale binding point to obtain the second input signal value of the display panel to be adjusted under each non-adjustable grayscale binding point.

[0073] In one embodiment, the computer device can pre-train an input signal assignment model, and then input each first input signal value, the model curve corresponding to each non-adjustable grayscale binding point, the first grayscale value of the display panel to be adjusted under each adjustable grayscale binding point, and the second grayscale value of the display panel to be adjusted under each non-adjustable grayscale binding point into the input signal assignment model. After assigning input signal values ​​to each non-adjustable grayscale binding point, the input signal assignment model outputs the second input signal value of the display panel to be adjusted under each non-adjustable grayscale binding point.

[0074] In another embodiment, the computer device can perform arithmetic operations on each first input signal value, the model curve corresponding to each non-adjustable grayscale binding point, the first grayscale value of the display panel to be adjusted at each adjustable grayscale binding point, and the second grayscale value of the display panel to be adjusted at each non-adjustable grayscale binding point to complete the input signal assignment and obtain the second input signal value of the display panel to be adjusted at each non-adjustable grayscale binding point. Optionally, the above arithmetic operations may include at least one of addition, multiplication, division, logarithmic, and exponential operations.

[0075] S400. Adjust the display brightness of the display panel to be adjusted based on each first input signal value and each second input signal value.

[0076] In practical applications, computer equipment can adjust the display brightness of the display panel to be adjusted according to the preset display brightness adjustment rules based on the values ​​of the first and second input signals.

[0077] In addition, the computer equipment can sort the first input signal values ​​and the second input signal values, and program them into the control chip of the electronic device to which the display panel to be adjusted belongs, in ascending or descending order, so as to adjust the display brightness of the display panel. Optionally, the aforementioned electronic device can be an electronic product with display function, such as a smartphone, smartwatch, smart bracelet, television, or computer.

[0078] The technical solution in this application embodiment obtains first input signal values ​​at multiple adjustable grayscale binding points based on the first display brightness values ​​of the display panel to be adjusted at multiple adjustable grayscale binding points acquired by the optical acquisition equipment on the production line. Based on each first input signal value, a model curve of the display panel to be adjusted at multiple non-adjustable grayscale binding points is determined. Then, based on each first input signal value, the model curve corresponding to each non-adjustable grayscale binding point, the first grayscale value of the display panel to be adjusted at each adjustable grayscale binding point, and the second grayscale value of the display panel to be adjusted at each non-adjustable grayscale binding point, the non-adjustable grayscale values ​​are adjusted accordingly. The method assigns input signal values ​​to the binding points to obtain the second input signal values ​​of the display panel to be adjusted under each non-adjustable grayscale binding point. Based on each first input signal value and each second input signal value, the display brightness of the display panel to be adjusted is adjusted. Here, adjustable grayscale binding points represent grayscale binding points where the display brightness value is lower than the upper limit of the brightness acquisition of the optical acquisition device, and non-adjustable grayscale binding points represent grayscale binding points where the display brightness value exceeds the upper limit of the brightness acquisition of the optical acquisition device. The above method can be based on the first input signal values ​​of the display panel under grayscale binding points where the display brightness value is lower than the upper limit of the brightness acquisition of the optical acquisition device. The input signal value (i.e., source value) is used to determine the model curve of the display panel at multiple grayscale binding points (i.e., non-adjustable grayscale binding points) where the display brightness value exceeds the brightness acquisition limit of the optical acquisition device. Based on the model curve corresponding to each non-adjustable grayscale binding point, the input signal value of the display panel at each non-adjustable grayscale binding point is assigned. This process can obtain the input signal value of the display panel at each non-adjustable grayscale binding point without the need for an optical acquisition device. On this basis, the display brightness of the display panel can be adjusted based on the input signal values ​​at multiple non-adjustable grayscale binding points and multiple adjustable grayscale binding points. This can increase the display brightness range of the configured display panel, enabling the display panel to improve its peak brightness during use and meet the display brightness configuration requirements. This allows the electronic equipment to meet market demands, improves the applicability of the electronic equipment, and increases the product yield at the time of delivery. At the same time, the above method does not require manual intervention, which not only reduces the accuracy of display brightness adjustment but also improves the speed and efficiency of display brightness adjustment.

[0079] The process of obtaining the first input signal value at multiple adjustable grayscale binding points based on the first display brightness value of the display panel to be adjusted at multiple adjustable grayscale binding points acquired by the optical acquisition equipment on the production line will be described below. In one embodiment, as... Figure 4 As shown, the steps in S100 above can be implemented in the following ways:

[0080] S110. Based on each first display brightness value, determine the first grayscale value of the display panel to be adjusted under each adjustable grayscale binding point.

[0081] In practical applications, computer devices can call a grayscale value reverse calculation tool and input the first display brightness value of the display panel to be adjusted under multiple adjustable grayscale binding points into the grayscale value reverse calculation tool in sequence. The grayscale value reverse calculation tool outputs the first grayscale value of the display panel to be adjusted under each adjustable grayscale binding point.

[0082] In addition, for any adjustable grayscale binding point, the computer device can perform a first conversion process on the first display brightness value of the display panel to be adjusted under the adjustable grayscale binding point to obtain the first grayscale value of the display panel to be adjusted under the adjustable grayscale binding point.

[0083] S120. Based on each first grayscale value, determine the first input signal value of the display panel to be adjusted under each adjustable grayscale binding point.

[0084] Specifically, the computer device can call the source value calculation function, and then input the first gray level value of the display panel to be adjusted under multiple adjustable gray level binding points into the source value calculation function in sequence. The source value calculation function outputs the first input signal value of the display panel to be adjusted under each adjustable gray level binding point.

[0085] In addition, for any adjustable grayscale binding point, the computer device can also perform a second conversion process on the first grayscale value of the display panel to be adjusted at the adjustable grayscale binding point to obtain the first input signal value of the display panel to be adjusted at that adjustable grayscale binding point. The specific implementation of this second conversion process may differ from that of the first conversion process described above.

[0086] The technical solution in this application embodiment determines the first grayscale value of the display panel to be adjusted under each adjustable grayscale binding point based on each first display brightness value, and determines the first input signal value of the display panel to be adjusted under each adjustable grayscale binding point based on each first grayscale value. The above method does not require complex algorithm processing, making the process of obtaining the input signal value of the display panel under each adjustable grayscale binding point simpler and reducing the complexity of obtaining the input signal value of the display panel under each adjustable grayscale binding point. This improves the speed, efficiency and accuracy of obtaining the input signal value of the display panel under each adjustable grayscale binding point.

[0087] The process of determining the first grayscale value of the display panel to be adjusted at each adjustable grayscale binding point based on each first display brightness value will be described below. In one embodiment, as... Figure 5 As shown, the steps in S110 above may include:

[0088] S111. For any adjustable grayscale binding point, find the first display brightness value of the display panel to be adjusted under the adjustable grayscale binding point in the mapping relationship table between different display brightness values ​​and different grayscale values.

[0089] It should be noted that the mapping table mentioned above can be pre-constructed based on the display brightness value and corresponding grayscale value of each point on the gamma 2.2 curve. The gamma 2.2 curve represents the relationship between multiple standard grayscale values ​​and their corresponding standard display brightness values ​​for any display panel, such as... Figure 6 The image shows a gamma 2.2 curve.

[0090] Specifically, for any adjustable grayscale binding point, the computer device can find the first display brightness value of the display panel to be adjusted under the adjustable grayscale binding point in the mapping relationship table between different display brightness values ​​and different grayscale values.

[0091] S112. Determine the grayscale value corresponding to the display brightness value that matches the first display brightness value in the mapping relationship table as the first grayscale value of the display panel to be adjusted under the adjustable grayscale binding point.

[0092] In this embodiment of the application, the computer device can determine the display brightness value that matches the first display brightness value in the mapping table, and determine the grayscale value corresponding to the display brightness value that matches the first display brightness value in the mapping table as the first grayscale value of the display panel to be adjusted under the adjustable grayscale binding point.

[0093] The technical solution in this application embodiment, for any adjustable grayscale binding point, searches for the first display brightness value of the display panel to be adjusted under the adjustable grayscale binding point in the mapping relationship table between different display brightness values ​​and different grayscale values. The grayscale value corresponding to the display brightness value that matches the first display brightness value in the mapping relationship table is determined as the first grayscale value of the display panel to be adjusted under the adjustable grayscale binding point. This process does not require complex algorithm processing, making the process of obtaining the grayscale value of the display panel under each adjustable grayscale binding point simpler and reducing the complexity of obtaining the grayscale value of the display panel under each adjustable grayscale binding point. This can improve the speed, efficiency and accuracy of obtaining the grayscale value of the display panel under each adjustable grayscale binding point. Furthermore, the above process is implemented by using a pre-constructed mapping relationship table in a search manner, which can greatly improve the speed and efficiency of obtaining the grayscale value of the display panel under each adjustable grayscale binding point.

[0094] The process of determining the first input signal value of the display panel to be adjusted at each adjustable grayscale binding point based on each first grayscale value will be described below. In one embodiment, as... Figure 7 As shown, the steps in S120 above can be implemented in the following ways:

[0095] S121. For any adjustable grayscale binding point, find the first grayscale value of the display panel to be adjusted under the adjustable grayscale binding point in the correlation table between different input signal values ​​and different grayscale values.

[0096] In practical applications, computer equipment can first obtain the grayscale values ​​on the gamma 2.2 curve, then obtain the input signal values ​​corresponding to each grayscale value, and establish the correlation between each input signal value and each grayscale value to obtain a correlation table.

[0097] S122. The input signal value corresponding to the gray level value that matches the first gray level value in the association table is determined as the first input signal value of the display panel to be adjusted under the adjustable gray level binding point.

[0098] In this embodiment of the application, the computer device can determine the grayscale value that matches the first grayscale value in the association table, and determine the input signal value corresponding to the grayscale value that matches the first grayscale value in the association table as the first input signal value of the display panel to be adjusted under the adjustable grayscale binding point.

[0099] The technical solution in this application embodiment, for any adjustable grayscale binding point, searches for the first grayscale value of the display panel to be adjusted under the adjustable grayscale binding point in the association table between different input signal values ​​and different grayscale values, and determines the input signal value corresponding to the grayscale value matching the first grayscale value in the association table as the first input signal value of the display panel to be adjusted under the adjustable grayscale binding point. This process does not require complex algorithm processing, making the process of obtaining the input signal value of the display panel under each adjustable grayscale binding point simpler and reducing the complexity of obtaining the input signal value of the display panel under each adjustable grayscale binding point. This can improve the speed, efficiency and accuracy of obtaining the input signal value of the display panel under each adjustable grayscale binding point. Furthermore, the above process is implemented by using a pre-built association table in a search manner, which can greatly improve the speed and efficiency of obtaining the input signal value of the display panel under each adjustable grayscale binding point.

[0100] The process of determining the model curve of the display panel to be adjusted under multiple non-adjustable grayscale binding points based on each first input signal value is described below. In one embodiment, the steps in S200 above may include: for any non-adjustable grayscale binding point, constructing the model curve of the display panel to be adjusted under the non-adjustable grayscale binding point based on the first grayscale value of the display panel to be adjusted under the target adjustable grayscale binding point and the corresponding first input signal value. The target adjustable grayscale binding point is any one of the multiple adjustable grayscale binding points.

[0101] Specifically, the computer device can call the model curve construction tool, input the first gray level value of the display panel to be adjusted under the target adjustable gray level binding point and the corresponding first input signal value into the model curve construction tool, and the model curve construction tool outputs the model curve of the display panel to be adjusted under the non-adjustable gray level binding point.

[0102] In addition, the computer device can construct a model curve of the display panel to be adjusted at any non-adjustable gray level binding point according to the first gray level value of the display panel to be adjusted at the target adjustable gray level binding point and the corresponding first input signal value, based on the preset model curve construction rules.

[0103] In one embodiment, the steps in S200 above may include: for any non-adjustable grayscale binding point, constructing a model curve of the display panel to be adjusted under the non-adjustable grayscale binding point based on the first grayscale value of the display panel to be adjusted under the target adjustable grayscale binding point and the corresponding first input signal value, and the actual display brightness value and actual input signal value of the standard display panel under the non-adjustable grayscale binding point; the standard display panel and the display panel to be adjusted are of the same type and size.

[0104] The computer equipment can acquire the actual display brightness values ​​of the standard display panel under each non-adjustable grayscale binding point by the high-configuration optical acquisition equipment, and then determine the corresponding actual input signal value and the corresponding actual grayscale value based on each actual display brightness value.

[0105] Furthermore, for any non-adjustable grayscale binding point, a fitting algorithm can be used to fit the model curve of the display panel to be adjusted under the non-adjustable grayscale binding point based on the first grayscale value and the corresponding first input signal value of the display panel to be adjusted under the target adjustable grayscale binding point, as well as the actual display brightness value and actual input signal value of the standard display panel under the non-adjustable grayscale binding point.

[0106] Among them, the upper limit of brightness acquisition of high-end optical acquisition equipment can be greater than the upper limit of brightness acquisition of the aforementioned optical acquisition equipment; the upper limit of brightness acquisition of high-end optical acquisition equipment can be 4000 nit, 5000 nit, 6000 nit, etc., as long as it can detect the maximum peak brightness of electronic devices in market demand.

[0107] In this embodiment of the application, the computer device can construct a model curve of the display panel to be adjusted at the non-adjustable grayscale binding point by using the method of constructing a right triangle at two points, based on the first grayscale value and the corresponding first input signal value of the display panel to be adjusted at the target adjustable grayscale binding point, and the actual display brightness value and actual input signal value of the standard display panel at the non-adjustable grayscale binding point.

[0108] It should be noted that the model curve of the display panel to be adjusted at the non-adjustable grayscale binding point can be understood as a right-angled triangle model formed by the target adjustable grayscale binding point and the standard display panel at the non-adjustable grayscale binding point in the curve diagram relating input signal value and grayscale value. Specifically, the target adjustable grayscale binding point in the curve diagram representing the first grayscale value and corresponding first input signal value of the display panel to be adjusted at the target adjustable grayscale binding point; the non-adjustable grayscale binding point in the curve diagram representing the actual grayscale value and corresponding actual input signal value of the standard display panel at the non-adjustable grayscale binding point. The standard display panel and the display panel to be adjusted are of the same type and size.

[0109] For example, Figure 8 To construct a curve relating input signal value and grayscale value, based on the first input signal value and first grayscale value of the display panel to be adjusted at adjustable grayscale binding points G207 and G175, and the actual input signal value and actual grayscale value of the standard display panel at non-adjustable binding points G255, G247 and G239, the right triangle formed by the dashed lines is the right triangle formed by the non-adjustable grayscale binding point G255 of the standard display panel and the adjustable grayscale binding point G207 of the display panel to be adjusted. The first angle of the model curve is angle θ in the figure, which is the acute angle of the model curve closest to the adjustable binding point.

[0110] Similarly, the model curve corresponding to the non-adjustable grayscale binding point G247 can be a right-angled triangle model composed of the adjustable grayscale binding point G207 and the non-adjustable grayscale binding point G247; the model curve corresponding to the non-adjustable grayscale binding point G239 can be a right-angled triangle model composed of the adjustable grayscale binding point G207 and the non-adjustable grayscale binding point G239.

[0111] It should be noted here that... Figure 8 The model curve corresponding to the non-adjustable grayscale binding point G255 is constructed using G207 as the adjustable grayscale binding point. In addition, the model curve corresponding to the non-adjustable grayscale binding point G255 can also be constructed using the adjustable grayscale binding point G175. This application does not limit the specific implementation of this application.

[0112] The technical solution in this application embodiment, for any non-adjustable grayscale binding point, constructs a model curve of the display panel to be adjusted under the non-adjustable grayscale binding point based on the first grayscale value of the display panel to be adjusted under the target adjustable grayscale binding point and the corresponding first input signal value. The target adjustable grayscale binding point is any one of multiple adjustable grayscale binding points. The above method can use the grayscale value of the display panel under the adjustable grayscale binding point and the corresponding input signal value to construct a model curve of the display panel under the non-adjustable grayscale binding point, so as to provide dependency information for subsequently obtaining the input signal value of the display panel under the non-adjustable grayscale binding point, thereby improving the feasibility of obtaining the input signal value of the display panel under each non-adjustable grayscale binding point without optical acquisition equipment.

[0113] In practical applications, when the display brightness value of the display panel exceeds the brightness acquisition limit of the optical acquisition device, the display brightness value of the display panel cannot be acquired by the optical acquisition device. The process of obtaining the corresponding input signal value of the display panel in this situation is described below. In one embodiment, as... Figure 9 As shown, the step in S300 above, which assigns input signal values ​​to each non-adjustable grayscale binding point based on each first input signal value, the model curve corresponding to each non-adjustable grayscale binding point, the first grayscale value of the display panel to be adjusted at each adjustable grayscale binding point, and the second grayscale value of the display panel to be adjusted at each non-adjustable grayscale binding point, to obtain the second input signal value of the display panel to be adjusted at each non-adjustable grayscale binding point, can be implemented in the following way:

[0114] S310. Based on the model curves corresponding to each non-adjustable grayscale binding point, each first grayscale value and each second grayscale value, obtain the grayscale offset of the display panel to be adjusted under each non-adjustable grayscale binding point.

[0115] In practical applications, computer devices can pre-train an algorithm model. For any non-adjustable grayscale binding point, the model curve corresponding to the non-adjustable grayscale binding point, each first grayscale value, and the second grayscale value corresponding to the non-adjustable grayscale binding point are all input into the algorithm model. The algorithm model outputs the grayscale offset of the display panel to be adjusted under the non-adjustable grayscale binding point, i.e., the offset.

[0116] In addition, the computer equipment can perform trigonometric function calculations, arithmetic operations, and other processing based on the model curve corresponding to the non-adjustable grayscale binding point, each first grayscale value, and the second grayscale value corresponding to the non-adjustable grayscale binding point, and obtain the grayscale offset of the display panel to be adjusted under the non-adjustable grayscale binding point based on the processing results.

[0117] In one embodiment, such as Figure 10As shown, the step in S310 above, which obtains the grayscale offset of the display panel to be adjusted at each non-adjustable grayscale binding point based on the model curve corresponding to each non-adjustable grayscale binding point, each first grayscale value, and each second grayscale value, may include:

[0118] S311. Obtain the first angle tangent function value of the model curve corresponding to each non-adjustable grayscale binding point.

[0119] Specifically, the computer device can obtain the first angle tangent function value of the model curve corresponding to each non-adjustable grayscale binding point from local storage, the cloud, hard drive, disk, etc. See also... Figure 9 In the embodiment shown, the first angle tangent function value tanθ of the model curve corresponding to the non-adjustable grayscale binding point G255 can be equal to a / b.

[0120] The first angle tangent function value of the model curve corresponding to each non-adjustable grayscale binding point is obtained by acquiring the first angle tangent function value of the model curve corresponding to each non-adjustable grayscale binding point using a tangent function value acquisition device.

[0121] S312. Determine the grayscale offset of the display panel to be adjusted under each non-adjustable grayscale binding point based on the values ​​of the first angle tangent function, the first grayscale value, and the second grayscale value.

[0122] In practical applications, for any non-adjustable grayscale binding point, the computer device can calculate the grayscale offset of the display panel to be adjusted under the non-adjustable grayscale binding point according to the preset calculation rules, based on the grayscale offset of the display panel to be adjusted under the non-adjustable grayscale binding point, the first grayscale value corresponding to at least two adjustable grayscale binding points, and the second grayscale value corresponding to the non-adjustable grayscale binding point.

[0123] In addition, the computer device can perform arithmetic operations on the grayscale offset of the display panel to be adjusted under the non-adjustable grayscale binding point, the first grayscale value corresponding to at least two adjustable grayscale binding points, and the second grayscale value corresponding to the non-adjustable grayscale binding point to obtain the grayscale offset of the display panel to be adjusted under the non-adjustable grayscale binding point.

[0124] In this embodiment, the grayscale offset of the display panel to be adjusted under the non-adjustable grayscale binding point can be equal to the first angle tangent function value of the model curve corresponding to the non-adjustable grayscale binding point multiplied by the difference between the second grayscale value under the non-adjustable grayscale binding point and the first grayscale value under any adjustable grayscale binding point.

[0125] For example, if any adjustable grayscale binding point is G207, then the grayscale offset G255_offset under the non-adjustable grayscale binding point G255 is tanθ*(255-207), where tanθ represents the first angle tangent function value of the model curve corresponding to the non-adjustable grayscale binding point G255, 255 represents the second grayscale value corresponding to the non-adjustable grayscale binding point, and 207 represents the first grayscale value corresponding to the non-adjustable grayscale binding point.

[0126] S320. Perform linear interpolation based on each first input signal value, each first grayscale value, and each second grayscale value to determine the initial input signal value of the display panel to be adjusted at each non-adjustable grayscale binding point.

[0127] Specifically, for any non-adjustable grayscale binding point, the computer device can use linear interpolation to perform linear interpolation on the first input signal value and the corresponding first grayscale value of the display panel to be adjusted at any two adjustable grayscale binding points, as well as the first grayscale value at the non-adjustable grayscale binding point, to obtain the initial input signal value of the display panel to be adjusted at the non-adjustable grayscale binding point. Optionally, the above linear interpolation method can be a two-point linear interpolation method, a Lagrange interpolation method, a Newton interpolation method, etc.

[0128] In this embodiment of the application, the computer device can perform arithmetic operations on the first input signal value and the corresponding first gray level value of the display panel to be adjusted under any two adjustable gray level binding points, as well as the first gray level value under the non-adjustable gray level binding point, to achieve linear interpolation processing and obtain the initial input signal value of the display panel to be adjusted under the non-adjustable gray level binding point.

[0129] For example, the initial input signal value under the non-adjustable grayscale binding point G255, i.e., the value of G255_source', can be equal to (G207_source value - G175_source value) * (255 - 207) / (207 - 175) + G207_source value.

[0130] S330. The initial input signal values ​​are superimposed with the corresponding grayscale offsets to obtain the second input signal values ​​of the display panel to be adjusted under each non-adjustable grayscale binding point.

[0131] Furthermore, for any non-adjustable grayscale binding point, the computer device can add the initial input signal value of the display panel to be adjusted at the non-adjustable grayscale binding point to the corresponding grayscale offset to obtain the second input signal value of the display panel to be adjusted at that non-adjustable grayscale binding point.

[0132] Referring back to the previous example, the second input signal value under the non-adjustable grayscale binding point G255 can be equal to the value of 'G255_source' + G255_offset. Table 1 below shows a statistical list of the target display brightness value, initial input signal value, first input signal value, grayscale offset, first angle tangent function value of the model curve, and actual display brightness value for the display panel to be adjusted under adjustable grayscale binding points (G175 and G207) and non-adjustable grayscale binding points (G239, G247, and G255). The target display brightness value can be understood as the display brightness value that the display panel to be adjusted is required to achieve under the corresponding grayscale binding point; the actual display brightness value of the display panel to be adjusted under the corresponding grayscale binding point can be equal to the actual display brightness value of the standard display panel under the corresponding grayscale binding point.

[0133] Table 1

[0134]

[0135] The technical solution in this application embodiment obtains the grayscale offset of the display panel to be adjusted at each non-adjustable grayscale binding point based on the model curve corresponding to each non-adjustable grayscale binding point, each first grayscale value, and each second grayscale value. Linear interpolation is then performed based on each first input signal value, each first grayscale value, and each second grayscale value to determine the initial input signal value of the display panel to be adjusted at each non-adjustable grayscale binding point. Finally, each initial input signal value is superimposed with its corresponding grayscale offset to obtain the second input signal value of the display panel to be adjusted at each non-adjustable grayscale binding point. This process does not require optical acquisition equipment to obtain the input signal value of the display panel at each non-adjustable grayscale binding point, and the processing is relatively simple, reducing the complexity of obtaining the input signal value of the display panel at each non-adjustable grayscale binding point. This improves the speed, efficiency, and accuracy of obtaining the input signal value of the display panel at each non-adjustable grayscale binding point.

[0136] The process of adjusting the display brightness of the display panel to be adjusted based on the first input signal value and the second input signal value will be described below. In one embodiment, as... Figure 11 As shown, the steps in S400 above can be implemented in the following ways:

[0137] S410. Determine the second display brightness value of the display panel to be adjusted under each non-adjustable grayscale binding point based on each second input signal value.

[0138] It should be noted that the computer device can use a display brightness value calculation function to calculate the second display brightness value of the display panel to be adjusted at each non-adjustable grayscale binding point based on each second input signal value.

[0139] In this embodiment of the application, the computer device can search for each second input signal value in a pre-built mapping relationship between different input signal values, different grayscale values ​​and different display brightness values, and determine the display brightness value corresponding to the input signal value that matches each second input signal value in the mapping relationship as the second display brightness value of the display panel to be adjusted under each non-adjustable grayscale binding point.

[0140] S420. Based on each first input signal value, each second input signal value, each first display brightness value, and each second display brightness value, construct an association information table between the input signal values ​​and display brightness values ​​of the display panel to be adjusted under multiple grayscale binding points; the multiple grayscale binding points include multiple non-adjustable grayscale binding points and multiple adjustable grayscale binding points.

[0141] In practical applications, computer devices can map each first input signal value to the corresponding first display brightness value, and map each second input signal value to the corresponding second display brightness value, and generate an association information table between the input signal values ​​and display brightness values ​​of the display panel to be adjusted under multiple grayscale binding points based on all mapping results.

[0142] S430. The associated information table is burned into the control chip of the electronic device to which the display panel to be adjusted belongs, so as to complete the adjustment of the display brightness of the display panel to be adjusted.

[0143] Furthermore, the computer equipment can burn or store the associated information table into the control chip of the electronic device to which the display panel to be adjusted belongs, so as to complete the adjustment of the display brightness of the display panel to be adjusted.

[0144] The technical solution in this application embodiment determines the second display brightness value of the display panel to be adjusted at each non-adjustable grayscale binding point based on each second input signal value. Based on each first input signal value, each second input signal value, each first display brightness value, and each second display brightness value, an association information table is constructed between the input signal values ​​and display brightness values ​​of the display panel to be adjusted at multiple grayscale binding points. This association information table is then burned into the control chip of the electronic device to which the display panel belongs, thereby completing the display brightness adjustment of the display panel to be adjusted. The multiple grayscale binding points include multiple non-adjustable grayscale binding points and multiple adjustable grayscale binding points. This method can adjust the display brightness of the display panel to be adjusted based on the second input signal values ​​of the display panel to be adjusted at each non-adjustable grayscale binding point and the first input signal values ​​of the display panel to be adjusted at each adjustable grayscale binding point, thereby increasing the display brightness range of the configured display panel. This allows the display panel to improve its peak brightness during use, meeting the display brightness configuration requirements of the display panel. Consequently, the electronic device to which the display panel belongs can meet market demands, improving the applicability of the electronic device and the product yield at the time of manufacture.

[0145] In one embodiment, this application also provides a display brightness adjustment method applied to a computer device, the method comprising the following steps:

[0146] (1) For any adjustable grayscale binding point, find the first display brightness value of the display panel to be adjusted under the adjustable grayscale binding point in the mapping relationship table between different display brightness values ​​and different grayscale values; where the adjustable grayscale binding point represents the grayscale binding point where the display brightness value is lower than the brightness acquisition limit of the optical acquisition device.

[0147] (2) Determine the grayscale value corresponding to the display brightness value that matches the first display brightness value in the mapping table as the first grayscale value of the display panel to be adjusted under the adjustable grayscale binding point.

[0148] (3) Find the first gray level value of the display panel to be adjusted under the adjustable gray level binding point in the correlation table between different input signal values ​​and different gray level values;

[0149] (4) The input signal value corresponding to the gray level value that matches the first gray level value in the association table is determined as the first input signal value of the display panel to be adjusted under the adjustable gray level binding point.

[0150] (5) For any non-adjustable grayscale binding point, construct the model curve of the display panel to be adjusted under the non-adjustable grayscale binding point based on the first grayscale value of the display panel to be adjusted under the target adjustable grayscale binding point and the corresponding first input signal value; wherein, the target adjustable grayscale binding point is any one of multiple adjustable grayscale binding points, and the non-adjustable grayscale binding point represents the grayscale binding point where the display brightness value exceeds the brightness acquisition limit of the optical acquisition device.

[0151] (6) Obtain the first angle tangent function value of the model curve corresponding to each non-adjustable gray level binding point;

[0152] (7) Determine the grayscale offset of the display panel to be adjusted under each non-adjustable grayscale binding point based on the values ​​of each first angle tangent function, each first grayscale value and each second grayscale value.

[0153] (8) Perform linear interpolation based on each first input signal value, each first gray level value and each second gray level value to determine the initial input signal value of the display panel to be adjusted under each non-adjustable gray level binding point.

[0154] (9) Superimpose each initial input signal value with the corresponding grayscale offset to obtain the second input signal value of the display panel to be adjusted under each non-adjustable grayscale binding point;

[0155] (10) Determine the second display brightness value of the display panel to be adjusted under each non-adjustable grayscale binding point based on each second input signal value;

[0156] (11) Based on each first input signal value, each second input signal value, each first display brightness value and each second display brightness value, construct an association information table between the input signal value and the display brightness value of the display panel to be adjusted under multiple gray level binding points; the multiple gray level binding points include multiple non-adjustable gray level binding points and multiple adjustable gray level binding points;

[0157] (12) Burn the associated information table into the control chip of the electronic device to which the display panel to be adjusted belongs, so as to complete the display brightness adjustment of the display panel to be adjusted.
