Description

Technical Field

[0001] This specification relates to the field of display technologies, and particularly to a brightness display method, apparatus, electronic device, and medium. Background Art

[0002] Currently, with the rapid development of organic light-emitting diode (OLED) display panels, they have quickly occupied the high-end product market in the market. With the development of the market, there is an increasing demand for higher brightness in high-end products, which poses a greater demand for the brightness of the screen. Higher brightness will significantly improve the user experience in strong light scenarios.

[0003] Current brightness display solutions need to rely on the internal resistance drop (IR drop) of the display panel. When the open pixel ratio (OPR) of the display panel is small, the brightness is forcibly increased to the target brightness. However, the forcibly increased brightness is not accurate enough, and due to limitations such as the circuit current and power consumption of the display panel, it is difficult for the brightness forcibly increased through the voltage drop to reach the target brightness. Summary of the Invention

[0004] To overcome the problems existing in the related art, this specification provides a brightness display method, apparatus, electronic device, and medium.

[0005] In the first aspect of any embodiment of this specification, a brightness display method is provided. The method includes:

[0006] Obtain preset first mapping information, where the first mapping information is the corresponding relationship between the first dynamic brightness value and the target brightness corresponding to the target light-emitting pixel ratio of the display panel, and the first mapping information is calibrated for the display panel under the condition of enabling global voltage drop compensation; the target light-emitting pixel ratio is a ratio lower than the preset light-emitting pixel ratio;

[0007] Based on the first mapping information, at the first dynamic brightness value, display the target brightness in the display panel at the target light-emitting pixel ratio.

[0008] In the second aspect of any embodiment of this specification, a brightness display apparatus is provided. The apparatus includes:

[0009] An information acquisition module, configured to acquire preset first mapping information, where the first mapping information is a corresponding relationship between a first dynamic brightness value and a target brightness corresponding to a target light-emitting pixel ratio of a display panel, and the first mapping information is obtained by calibrating the display panel when global voltage drop compensation is enabled; the target light-emitting pixel ratio is a ratio lower than a preset light-emitting pixel ratio;

[0010] A brightness display module, configured to display the target brightness in the display panel with the target light-emitting pixel ratio at the first dynamic brightness value based on the first mapping information.

[0011] According to a third aspect of any embodiment of the present specification, an electronic device is provided, including:

[0012] A processor;

[0013] A memory for storing processor-executable instructions;

[0014] Wherein, the processor realizes the method described in any embodiment of the present specification by running the executable instructions.

[0015] According to a fourth aspect of any embodiment of the present specification, a computer-readable storage medium is provided, on which computer instructions are stored, and when the instructions are executed by a processor, the steps of the method described in any embodiment of the above present specification are realized.

[0016] The technical solutions provided by the embodiments of the present specification may include the following beneficial effects:

[0017] According to the above embodiments, by acquiring the preset first mapping information, and obtaining the corresponding relationship between the first dynamic brightness value and the target brightness corresponding to the target light-emitting pixel ratio of the display panel according to the first mapping information. Since the corresponding relationship between the first dynamic brightness value and the target brightness corresponding to the target light-emitting pixel ratio of the display panel is obtained by calibrating the display panel when global voltage drop compensation is enabled, the target brightness displayed by the display panel with the target light-emitting pixel ratio at the first dynamic brightness value is more accurate; and, since the target light-emitting pixel ratio is a ratio lower than the preset light-emitting pixel ratio, even at a smaller target light-emitting pixel ratio, due to the enabling of global voltage drop compensation, the current in the display panel with the target light-emitting pixel ratio can be reduced, and the brightness can be maximally increased while ensuring that the circuit current does not exceed the limit, thereby raising the display brightness of the display panel to the target brightness.

[0018] It should be understood that the above general description and subsequent detailed description are only exemplary and explanatory, and cannot limit the present specification. Description of the Drawings

[0027] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this specification.

[0029] It should be understood that although terms such as first, second, and third may be used in this specification to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this specification, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to a determination".

[0030] In the related art, due to the different luminous pixel ratios in the display panel, the range of the image displayed on the display panel is also different. The lower the luminous pixel ratio in the display panel, the smaller the range of the image displayed on the display panel, and the higher the peak brightness that the display panel can achieve.

[0031] In the current brightness display scheme, usually when the luminous pixel ratio of the display panel is small and a higher display brightness is required, it is necessary to rely on the voltage drop of the display panel to forcibly increase the brightness to the target brightness. However, the forcibly increased brightness is not accurate enough, and due to limitations such as the circuit current and power consumption of the display panel, it is very difficult for the brightness forcibly increased through the voltage drop to reach the target brightness.

[0032] To solve the above problems, the embodiments of this specification propose a brightness display method. To further illustrate this specification, the following embodiments are provided:

[0033] Please refer to Figure 1 , Figure 1 is a flowchart of a brightness display method shown in this specification according to an exemplary embodiment. This method can be executed by a terminal device equipped with a display panel and is applied to a strong light scenario. Among them, the terminal device is an electronic device that provides services for customers, such as: mobile phones, computers, etc. The display panel is an OLED panel. The strong light scenario is a scenario that requires a higher brightness to improve the display effect, such as: direct sunlight outdoors, playing HDR videos, etc.

[0034] This brightness display method may include the following steps:

[0035] Step 102: Obtain preset first mapping information. The first mapping information is the corresponding relationship between the first dynamic brightness value and the target brightness corresponding to the target luminous pixel ratio of the display panel. The first mapping information is calibrated for the display panel under the condition of enabling global voltage drop compensation; the target luminous pixel ratio is a ratio lower than the preset luminous pixel ratio.

[0036] In this step, the terminal device can obtain preset first mapping information. The first mapping information is the corresponding relationship between the first dynamic brightness value and the target brightness corresponding to the target light-emitting pixel ratio of the display panel. The first dynamic brightness value, the target light-emitting pixel ratio, and the target brightness are preset.

[0037] Among them, the target light-emitting pixel ratio is a ratio lower than the preset light-emitting pixel ratio, and the target brightness is the highest peak brightness determined based on the hardware performance of the terminal device. The first dynamic brightness value is the dynamic brightness value (Display Brightness Value, DBV) corresponding to the target brightness and the target light-emitting pixel ratio added in the chip of the terminal device.

[0038] The preset light-emitting pixel ratio is the lowest light-emitting pixel ratio set according to the aperture size of the instrument for measuring the display brightness of the display panel, such as 1%, 5%, etc. Figure 2 A schematic diagram of a 1% light-emitting pixel ratio is shown. The first light-emitting pixel area 201 is the area of the display panel for displaying the image to be displayed. The proportion of the number of pixels in the first light-emitting pixel area 201 to the total number of pixels in the display panel 20 is 1%.

[0039] It can be understood that Figure 2 the first light-emitting pixel area 201 in is only an example, and the embodiments of this specification do not limit the shape and position of the light-emitting pixel area.

[0040] The acquisition method of the first mapping information can be obtained according to the first brightness node in the preset mapping relationship.

[0041] The preset mapping relationship includes several brightness nodes. The preset mapping relationship can represent the corresponding relationship between the dynamic brightness value and the brightness of the display panel in the form of a brightness curve, a brightness table, etc. The first brightness node is used to characterize the mapping relationship between the first dynamic brightness value, the target light-emitting pixel ratio, and the target brightness.

[0042] The first mapping information is calibrated for the display panel when the global voltage drop compensation (Global IR drop compensation, GIR) is enabled. When the display panel is in the target light-emitting pixel ratio, the light-emitting pixel area of the display panel is smaller, and the current in the display panel is larger.

[0043] The global voltage drop compensation can be used to reduce the current of the display panel in the target light-emitting pixel ratio. The compensation method of the global voltage drop compensation, for example, can be to respectively determine the compensation gray level of the corresponding row of pixels according to the voltage drop of each row of pixels in the display panel for gray level compensation, or to compensate the voltage drop of each area according to the voltage drop compensation value of several areas in the display panel. The embodiments of this specification do not limit this.

[0044] To further illustrate the first mapping information, Figure 3 a schematic diagram of a brightness curve is shown. As Figure 3 shown, taking the preset mapping relationship as an example of the brightness curve, the abscissa of the brightness curve represents the dynamic brightness value, the ordinate represents the brightness value of the display panel, and the unit of the brightness value can be nits (nit).

[0045] Exemplarily, in the preset mapping relationship, a first dynamic brightness value corresponding to a target luminous pixel ratio at a target brightness is added. The brightness curve includes but is not limited to: a first brightness node 301, a second brightness node 302, and several other brightness nodes.

[0046] Taking the first dynamic brightness value as DBV 4095 as an example, the first dynamic brightness value corresponding to the first brightness node 301 is DBV4095, the target luminous pixel ratio corresponding to the first brightness node 301 is a preset 1%, and the target brightness corresponding to the first brightness node 301 is a preset 3150 nit. The second brightness node 302 will be further described in subsequent embodiments.

[0047] After completing the global voltage drop compensation debugging, the global voltage drop compensation can be enabled to perform gamma calibration on the display panel. According to the dynamic brightness value in the preset mapping relationship, the current in the display panel with a luminous pixel ratio corresponding to the dynamic brightness value is debugged to obtain a gamma curve corresponding to the dynamic brightness value.

[0048] Based on the gamma curve, the brightness of the display panel is adjusted so that the display panel with a target luminous pixel ratio can display the corresponding brightness at this dynamic brightness value. Among them, the gamma curve refers to the relationship curve between different gray levels and brightness.

[0049] When the global voltage drop compensation is enabled, the mapping relationships corresponding to all brightness nodes in the preset mapping relationship can be corrected so that the display panel displays the brightness corresponding to the brightness node at the dynamic brightness value corresponding to the brightness node.

[0050] Specifically, based on the target brightness and the first dynamic brightness value, a whiteboard image can be used to debug the display panel with a target luminous pixel ratio so that the display panel with a target luminous pixel ratio displays the target brightness at the first dynamic brightness value.

[0051] As Figure 3 shown, when the global voltage drop compensation is enabled, at the first dynamic brightness value DBV 4095, the white image of the display panel with a 1% luminous pixel ratio is debugged according to the target brightness of 3150 nit, so that the display panel with a 1% luminous pixel ratio displays the target brightness of 3150 nit at DBV 4095.

[0052] As described above, by debugging the display panel with a target luminous pixel ratio based on the target brightness and the first dynamic brightness value, so that the display panel displays the target brightness at the first dynamic brightness value, the target brightness displayed by the display panel with the target luminous pixel ratio at the first dynamic brightness value can be made more accurate.

[0053] Further, enabling global voltage drop compensation can be to respectively determine the compensation gray levels for the pixels in each row of the display panel according to the voltage drops of the pixels in each row, and perform gray level compensation.

[0054] After enabling global voltage drop compensation, perform gamma correction on the display panel. At the first dynamic brightness value, measure the brightness of different gray levels with an optical probe, debug the current in the display panel with the target luminous pixel ratio at the first dynamic brightness value, and obtain the gamma curve corresponding to the first dynamic brightness value. Based on the target brightness corresponding to the maximum gray level in the gamma curve, adjust the display panel to display the target brightness.

[0055] As Figure 3 shown, after enabling global voltage drop compensation, at the first dynamic brightness value DBV 4095, debug the current in the display panel with a 1% luminous pixel ratio, and obtain the gamma curve corresponding to DBV 4095. Based on the target brightness corresponding to the maximum gray level in the gamma curve, adjust the target brightness displayed by the display panel with a 1% luminous pixel ratio at DBV 4095 to 3150 nit.

[0056] As described above, by performing gamma correction after enabling global voltage drop compensation, debugging the current in the display panel with the target luminous pixel ratio, obtaining the gamma curve corresponding to the first dynamic brightness value, and based on the gamma curve, adjusting the target brightness displayed by the display panel, the target brightness and contrast displayed by the display panel can be more accurately controlled, and the quality of the displayed image in the display panel with the target luminous pixel ratio can be improved.

[0057] Step 104: Based on the first mapping information, at the first dynamic brightness value, display the target brightness in the display panel with the target luminous pixel ratio.

[0058] In this step, the terminal device can, based on the first mapping information obtained in step 102, display the target brightness in the display panel with the target luminous pixel ratio at the first dynamic brightness value.

[0059] Please continue to refer to Figure 3 , the terminal device can, based on the correspondence between the first dynamic brightness value, the target luminous pixel ratio, and the target brightness, display the target brightness of 3150 nit in the display panel with a 1% target luminous pixel ratio at the first dynamic brightness value DBV 4095.

[0060] The brightness display method of this embodiment obtains the preset first mapping information, and obtains the corresponding relationship between the first dynamic brightness value and the target brightness corresponding to the target light-emitting pixel ratio of the display panel according to the first mapping information. Since the corresponding relationship between the first dynamic brightness value and the target brightness corresponding to the target light-emitting pixel ratio of the display panel is calibrated for the display panel under the condition of enabling global voltage drop compensation, the target brightness displayed by the display panel at the target light-emitting pixel ratio under the first dynamic brightness value is more accurate.

[0061] Moreover, since the target light-emitting pixel ratio is a ratio lower than the preset light-emitting pixel ratio, even at a small target light-emitting pixel ratio, due to enabling global voltage drop compensation, the current in the display panel at the target light-emitting pixel ratio can be reduced. Without exceeding the limit of the circuit current, the brightness is maximally increased, thereby raising the display brightness of the display panel to the target brightness.

[0062] Furthermore, before obtaining the first mapping information in the preset brightness curve in step 102, the first mapping information can be stored. The first mapping information includes: target brightness, target light-emitting pixel ratio, and first dynamic brightness value.

[0063] The terminal device can display the target brightness in the display panel at the target light-emitting pixel ratio based on the stored first mapping information at the first dynamic brightness value.

[0064] As described above, by storing the first mapping information before obtaining the first mapping information in the preset brightness curve, it is convenient to subsequently display the target brightness in the display panel at the target light-emitting pixel ratio based on the stored first mapping information at the first dynamic brightness value, improving the accuracy of the corresponding relationship among the target brightness, the target light-emitting pixel ratio, and the first dynamic brightness value.

[0065] In the foregoing embodiment, the target brightness display process of the terminal device is introduced. In the following embodiment, a more detailed description will be given on how to adjust the brightness of the display panel, and it can be applied to any of the above embodiments.

[0066] In one embodiment, the terminal device can obtain the preset second mapping information. The second mapping information is the corresponding relationship between the second dynamic brightness value and the normal brightness corresponding to the normal light-emitting pixel ratio of the display panel.

[0067] The second mapping information is calibrated for the display panel under the condition of enabling global voltage drop compensation.

[0068] The second dynamic brightness value, the conventional light-emitting pixel ratio, and the conventional brightness are preset. Among them, the ratio of the conventional light-emitting pixel ratio is 100%, and the conventional brightness is the peak brightness determined based on the display panel with a 100% light-emitting pixel ratio. The second dynamic brightness value is the dynamic brightness value corresponding to the conventional brightness in the chip of the terminal device.

[0069] Figure 4 A schematic diagram of a 100% light-emitting pixel ratio is shown. The second light-emitting pixel region 401 is the region of the display panel that displays the image to be displayed. The ratio of the number of pixels in the second light-emitting pixel region 401 to the total number of pixels in the display panel is 100%.

[0070] The terminal device can, based on the second mapping information, display the conventional brightness on the display panel with a conventional light-emitting pixel ratio at the second dynamic brightness value.

[0071] Please continue to refer to Figure 3 , taking the second dynamic brightness value as DBV 3900 as an example. The second dynamic brightness value corresponding to the second brightness node 302 in the preset mapping relationship is DBV 3900. The conventional light-emitting pixel ratio corresponding to the second brightness node 302 is the preset 100%, and the conventional brightness corresponding to the second brightness node 302 is the preset 1400 nit.

[0072] When the global voltage drop compensation is enabled, at the second dynamic brightness value of DBV 3900, the display panel with a 100% light-emitting pixel ratio is debugged according to the conventional brightness of 1400 nit, so that the display panel with a 100% light-emitting pixel ratio can display the conventional brightness of 1400 nit at DBV 3900.

[0073] The terminal device can, based on the correspondence relationship among the second dynamic brightness value, the conventional light-emitting pixel ratio, and the conventional brightness in the second mapping information, display the conventional brightness of 1400 nit on the display panel with a 100% conventional light-emitting pixel ratio at the second dynamic brightness value of DBV 3900.

[0074] As described above, by obtaining the second mapping information obtained by calibrating the display panel under the condition of enabling the global voltage drop compensation, the correspondence relationship between the second dynamic brightness value and the conventional brightness corresponding to the conventional light-emitting pixel ratio of the display panel can be obtained. Based on the second mapping information, the conventional brightness can be displayed on the display panel with a conventional light-emitting pixel ratio at the second dynamic brightness value, which is convenient for dynamically adjusting the brightness of the display panel corresponding to the dynamic brightness value between the first dynamic brightness value and the second dynamic brightness value in the subsequent process.

[0075] Further, in the automatic brightness mode, the sensor in the terminal device can determine the required brightness of the display panel according to the detected light intensity of the external environment. When the required brightness of the display panel does not reach the conventional brightness, the terminal device gives the dynamic brightness value corresponding to the detected light intensity according to the detected light intensity of the external environment. According to the corresponding relationship between the dynamic brightness value and the brightness of the display panel in the preset mapping relationship, the brightness corresponding to the dynamic brightness value is displayed.

[0076] When the required brightness of the display panel reaches the conventional brightness, the terminal device can adjust the brightness of the display panel according to the target interval in the preset mapping relationship.

[0077] Among them, the target interval in the preset mapping relationship is an interval determined based on the first mapping information and the second mapping information, and can be used to represent the corresponding relationship between the dynamic brightness value and the brightness of the display panel.

[0078] The terminal device can obtain the brightness interval of the display panel corresponding to the dynamic brightness value interval in the preset mapping relationship according to the dynamic brightness value interval in the target interval. Based on the dynamic brightness value in the dynamic brightness value interval, the brightness of the display panel is adjusted.

[0079] For example, the obtaining method of the dynamic brightness value in the dynamic brightness value interval can be set according to the gray level in the display panel, or can be set according to the luminous pixel ratio in the display panel.

[0080] Please continue to refer to Figure 3 , continuing to take the preset mapping relationship as the brightness curve as an example, the target interval in the preset mapping relationship can be the line segment interval determined according to the first brightness node 301 corresponding to the first mapping information and the second brightness node 302 corresponding to the second mapping information in the preset mapping relationship.

[0081] When the required brightness of the display panel reaches the conventional brightness of 1400 nit, correspondingly, the dynamic brightness value reaches the second dynamic brightness value DBV 3900. The terminal device can obtain the brightness interval (1400 nit to 3150 nit) of the display panel corresponding to the dynamic brightness value in the preset mapping relationship according to the dynamic brightness value interval (DBV 3900 to DBV 4095) in the target interval.

[0082] Based on the dynamic brightness value in the dynamic brightness value interval from DBV 3900 to DBV 4095, the luminous pixel ratio of the display panel is the luminous pixel ratio corresponding to the dynamic brightness value. According to the brightness corresponding to the dynamic brightness value, the brightness of the display panel is adjusted so that the display panel with the luminous pixel ratio corresponding to the dynamic brightness value displays the brightness corresponding to the dynamic brightness value.

[0083] As described above, when the required brightness of the display panel reaches the normal brightness, the brightness of the display panel is adjusted according to the target interval in the preset mapping relationship. If the luminous pixel ratio is increased at the first dynamic brightness value and the target brightness remains unchanged, increasing the luminous pixel ratio may cause excessive current, resulting in the inability to load the current or even burning out the circuit. Since the brightness of the display panel is determined by the dynamic brightness value in the target interval of the preset mapping relationship, the luminous pixel ratio of the display panel is the luminous pixel ratio corresponding to the dynamic brightness value, and the brightness of the display panel can be dynamically adjusted, and the brightness change transition will be relatively smooth, avoiding abnormal circuit conditions such as jumps.

[0084] Further, in order to further illustrate how to adjust the brightness, Figure 5 A flowchart of a method for adjusting brightness is shown. As Figure 5 shown, the method may include the following steps:

[0085] Step 502: Obtain the average gray level in the display panel.

[0086] In this step, the terminal device can read the gray levels of all pixels of the displayed image in the display panel, calculate the average gray level of all pixels, so as to obtain the average gray level of the displayed content in the display panel. Among them, the average gray level is used to characterize the brightness of the displayed image in the display panel.

[0087] Step 504: Based on the first dynamic brightness value and the second dynamic brightness value, determine a third dynamic brightness value according to the average gray level.

[0088] In this step, the chip in the terminal device can determine the third dynamic brightness value based on the first dynamic brightness value and the second dynamic brightness value, according to the average gray level obtained in step 502. Among them, the third dynamic brightness value is the dynamic brightness value in the dynamic brightness value interval within the target interval.

[0089] The chip can calculate the third dynamic brightness value according to the following formula (1):

[0090]

[0091] where DBV represents the third dynamic brightness value, a represents the first dynamic brightness value, b represents the second dynamic brightness value, and x represents the average gray level.

[0092] Please continue to refer to Figure 3 , taking the average gray level as x%, the chip can calculate the third dynamic brightness value according to the following formula (2):

[0093]

[0094] Wherein, DBV represents the third dynamic brightness value, 4095 is the first dynamic brightness value, 3900 is the second dynamic brightness value, and x represents the average gray scale.

[0095] Step 506: Display the brightness of the display panel according to the third dynamic brightness value.

[0096] In this step, the display panel can obtain the luminous pixel ratio and brightness corresponding to the third dynamic brightness value in the preset mapping relationship according to the third dynamic brightness value obtained by the chip. At the third dynamic brightness value, the brightness corresponding to the third dynamic brightness value is displayed in the display panel with the luminous pixel ratio corresponding to the third dynamic brightness value.

[0097] As described above, by obtaining the average gray scale in the display panel, based on the first dynamic brightness value and the second dynamic brightness value, determining the third dynamic brightness value according to the average gray scale, and according to the third dynamic brightness value, displaying the brightness corresponding to the third dynamic brightness value in the display panel with the luminous pixel ratio corresponding to the third dynamic brightness value, the dynamic brightness value can be dynamically adjusted along with the change of the average gray scale in the display panel, without restricting the scenario of the display target brightness, and ensuring to freely enter the high-brightness scenario under the condition of circuit safety.

[0098] Figure 6 FIG. is a schematic structural diagram of an electronic device shown according to an exemplary embodiment of the present specification. The electronic device may be, for example, a mobile phone, a computer, a digital broadcast terminal, a messaging device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, etc. Refer to Figure 6 , at the hardware level, the electronic device includes a processor 602, an internal bus 604, a network interface 606, a memory 608, and a non-volatile memory 610. Of course, it may also include other hardware required for other services. The processor 602 reads the corresponding computer program from the non-volatile memory 610 into the memory 608 and then runs it, forming a brightness display device logically. Of course, in addition to the software implementation manner, the present application does not exclude other implementation manners, such as a logic device or a combination of software and hardware, etc. That is to say, the execution subject of the following processing flow is not limited to each logic unit, and may also be hardware or a logic device.

[0099] Figure 7 FIG. is a block diagram of a brightness display device shown according to an exemplary embodiment of the present specification. Refer to Figure 7 , the device may include: an information acquisition module 702 and a brightness display module 704, wherein:

[0100] The information acquisition module 702 is configured to acquire preset first mapping information, where the first mapping information is the corresponding relationship between a first dynamic brightness value and a target brightness corresponding to a target light-emitting pixel ratio of the display panel. The first mapping information is calibrated for the display panel under the condition of enabling global voltage drop compensation; the target light-emitting pixel ratio is a ratio lower than a preset light-emitting pixel ratio.

[0101] The brightness display module 704 is configured to display the target brightness in the display panel at the target light-emitting pixel ratio based on the first mapping information at the first dynamic brightness value.

[0102] In one example, the device further includes: a display panel debugging module 706, which is configured to debug the display panel at the target light-emitting pixel ratio based on the target brightness and the first dynamic brightness value before acquiring the preset first mapping information, so that the brightness of the display panel displays the target brightness at the first dynamic brightness value.

[0103] In one example, when the display panel debugging module 706 is configured to debug the display panel at the target light-emitting pixel ratio based on the target brightness and the first dynamic brightness value, it includes: enabling the global voltage drop compensation; debugging the current in the display panel at the target light-emitting pixel ratio according to the first dynamic brightness value to obtain a gamma curve corresponding to the first dynamic brightness value; and adjusting the target brightness displayed by the display panel based on the gamma curve.

[0104] In one example, the information acquisition module 702 is further configured to acquire preset second mapping information, where the second mapping information is the corresponding relationship between a second dynamic brightness value and a conventional brightness corresponding to a conventional light-emitting pixel ratio of the display panel. The second mapping information is calibrated for the display panel under the condition of enabling the global voltage drop compensation; the proportion of the conventional light-emitting pixel ratio is 100%; the brightness display module 704 is further configured to display the conventional brightness in the display panel at the conventional light-emitting pixel ratio based on the second mapping information at the second dynamic brightness value.

[0105] In one example, the brightness display module 704 is further configured to adjust the brightness of the display panel according to a target interval in a preset mapping relationship when the brightness required by the display panel reaches the conventional brightness. The target interval in the preset mapping relationship is the corresponding relationship between the dynamic brightness value and the brightness of the display panel determined based on the first mapping information and the second mapping information.

[0106] In one example, when the brightness display module 704 is used to adjust the brightness of the display panel according to a target interval in a preset mapping relationship, it includes: obtaining an average gray level in the display panel; determining a third dynamic brightness value based on the first dynamic brightness value and the second dynamic brightness value according to the average gray level; and displaying the brightness of the display panel according to the third dynamic brightness value.
