[0028] In order to facilitate the understanding of the present application, the present application will be described in more detail below with reference to the relevant drawings. The drawings show preferred embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0029] The dimming configuration method provided by the embodiments of the present application is used to configure the dimming relationship of a light-emitting diode, for example, by changing the dimming mode when the light-emitting diode is dimmed, so that the light-emitting diode presents a linear and uniform change effect in the process of gradually increasing or gradually decreasing brightness, or the light-emitting diode presents an exponential change effect in the process of gradually decreasing brightness, etc. Specifically, the light-emitting diode can be a light-emitting diode on a mobile phone or other electronic device as a breathing light, or can be an electronic device applied to other display requirements with gradually increasing or gradually decreasing brightness, and the specific implementation is not limited and can be selected according to actual needs.

[0030] Referring to Figure 1 The present application provides a dimming configuration method, which includes steps 102, 104 and 106.

[0031] Step 102: determining an operation offset and a basic brightness configuration relationship according to a brightness configuration range of the light-emitting diode.

[0032] Specifically, the basic brightness configuration relationship represents the corresponding relationship between the basic brightness configuration parameter and the basic brightness parameter, and the brightness configuration range includes a plurality of brightness configuration parameters.

[0033] The brightness configuration range is the range of the brightness configuration parameter when the segmented dimming control is performed. The brightness configuration parameter is the brightness value that the LED needs to reach when the dimming control is performed, such as 32, 64, 128, and the like. The brightness parameter is the register value used to generate different duty cycle PWM signals when the LED is dimmed. The operation offset is the brightness parameter increment that the base brightness configuration parameter needs to increase when the base brightness configuration relationship is mapped to the current brightness configuration range.

[0034] The base brightness configuration relationship is the corresponding relationship between the base brightness configuration parameter and the base brightness parameter at different LED brightnesses that is set in advance. In the base brightness configuration relationship, the base brightness configuration parameter and the base brightness parameter can be in a linear relationship or a nonlinear relationship (such as an exponential relationship, a multi-segment linear relationship combination, and the like), which is not limited in particular and can be selected according to actual needs. The form of the base brightness configuration relationship is not unique and can be a graph, a table, a database, and the like, which is not limited in particular. In order to facilitate understanding of the technical solution of the present application, the following embodiments can be understood as a table, that is, the dimming configuration is performed by looking up the table.

[0035] The human eye is more likely to perceive changes in brightness when the LED lamp is dimmer, and the human eye is less likely to perceive changes in brightness when the LED lamp is brighter. Therefore, the intervals of different brightness values can be used as different brightness configuration ranges. Different operation offsets and base brightness configuration relationships are configured for different brightness configuration ranges. In actual scenarios, after the brightness configuration range is determined, the operation offset and the base brightness configuration relationship that match the brightness configuration range are determined, and the brightness configuration range is configured by using the operation offset and the base brightness configuration relationship.

[0036] Step 104, determining the brightness parameter corresponding to the different brightness configuration parameters in the brightness configuration range according to the brightness configuration range, the operation offset, and the base brightness configuration relationship.

[0037] Specifically, the brightness configuration parameter can be part of the bit of the brightness configuration range. After the operation offset and the base brightness configuration relationship corresponding to the brightness configuration range are obtained, the base brightness configuration relationship can be analyzed by matching, and the brightness parameter corresponding to the different brightness configuration parameters can be finally calculated by combining the operation offset and the result of the matching analysis.

[0038] It can be understood that in actual scenarios, all brightness configuration ranges can follow a table lookup rule (that is, the base brightness configuration relationship described above), that is, the operation offset and the base brightness configuration relationship corresponding to all brightness configuration ranges are consistent. At this time, the brightness parameter corresponding to all brightness configuration parameters can be obtained by analyzing the obtained operation offset and base brightness configuration relationship.

[0039] In another embodiment, different brightness configuration ranges can follow different lookup table rules, in which case different brightness configuration ranges need to be matched to obtain different operation offset and basic brightness configuration relationships respectively, and the corresponding brightness parameters are calculated respectively. In actual scenarios, the selection can be made in combination with actual needs, which is not limited herein.

[0040] In step 106, the brightness configuration relationship is determined according to the brightness configuration parameters and the corresponding brightness parameters in the brightness configuration range.

[0041] Specifically, the brightness configuration relationship represents that the brightness parameter gradually changes in a gradually increasing manner with the change of the brightness configuration parameter, and the brightness configuration relationship is used for the dimming control of the light-emitting diode.

[0042] It should be pointed out that the change manner of the growth rate is also different according to actual needs, which can be uniform (for example, gradually increasing or gradually decreasing) change following the change of the brightness configuration parameter, or non-uniform change (for example, first increasing and then decreasing) following the change of the brightness configuration parameter, which is not limited.

[0043] In order to facilitate understanding of the technical solutions of the present application, the following embodiments represent that the brightness parameter gradually increases in a gradually increasing manner with the increase of the brightness configuration parameter. In the scenario of this embodiment, due to the biological characteristics of the human visual nerve, the LED is more sensitive to the brightness change when it is dimmer, that is, the brightness change is more easily perceived; when the LED is brighter, it is less sensitive to the brightness change, that is, the brightness change is less easily perceived. Therefore, in order to make the brightness change faster when the brightness is brighter, so that the brightness change is perceived by the human eye, the growth rate of the brightness parameter needs to be gradually increased with the increase of the brightness configuration parameter.

[0044] It should be pointed out that the brightness parameter gradually increases in a gradually increasing manner, which can be an exponential change trend, or a non-exponential change trend (there is a certain deviation from the exponential change, which can be understood as a quasi-exponential change), which is selected in combination with actual scenarios, which is not limited herein. In order to facilitate understanding of the technical solutions of the present application, the following embodiments can be understood as an exponential change trend.

[0045] In an actual scenario, the brightness parameter is essentially a register value, and the greater the brightness parameter, the greater the duty cycle of the corresponding pulse width modulation signal, and accordingly, the brighter the LED. Configuring the brightness parameter to have a growth rate that gradually increases with the increase of the brightness configuration parameter will cause the brightness to change more when the brightness is brighter, i.e., the duty cycle of the PWM signal is greater, and even if the human eye is slow to respond, the brightness change can still be perceived. When the brightness is dimmer, the brightness parameter changes less, i.e., the duty cycle of the PWM signal is smaller, and at this time, due to the sensitivity of the human eye, the brightness change can also be perceived by the human eye.

[0046] After determining the brightness configuration relationship, the control device can control the light emission of the LED according to the brightness configuration relationship. In the dim-to-bright change mode, the brightness parameter (duty cycle of the PWM signal) gradually increases with time, and the growth rate becomes larger and larger, so as to achieve slower brightness change when the brightness is lower, and faster brightness change when the brightness is higher. In the bright-to-dim change mode, the brightness parameter (duty cycle of the PWM signal) gradually decreases with time, and the decrease rate becomes smaller and smaller, so as to achieve slower brightness change when the brightness is lower, and faster brightness change when the brightness is higher.

[0047] The above light modulation configuration method can determine the operation offset and the basic brightness configuration relationship according to the brightness configuration range of the light-emitting diode, and then determine the brightness parameter corresponding to each brightness configuration parameter in the brightness configuration range in combination with the brightness configuration range, the operation offset, and the basic brightness configuration relationship. Finally, the brightness configuration relationship is determined based on the brightness configuration parameter and the corresponding brightness parameter. According to the scheme, the brightness configuration relationship in which the brightness parameter gradually changes at a growth rate with the change of the brightness configuration parameter can be obtained according to actual requirements, for example, the brightness parameter gradually increases at a growth rate that gradually increases with the increase of the brightness configuration parameter, or the brightness parameter gradually increases at a growth rate that gradually increases with the decrease of the brightness configuration parameter, etc. Subsequent light-emitting diode lighting control based on this can change the actual display brightness at different brightness change speeds in different states, thereby meeting different light modulation requirements and improving the light modulation effect of the light-emitting diode.

[0048] Further, in a more detailed embodiment, a brightness configuration relationship in which the brightness parameter gradually increases at a growth rate that gradually increases with the increase of the brightness configuration parameter can be obtained, and subsequent light-emitting diode lighting control based on this can change the brightness faster when the light-emitting diode is brighter, and change the brightness slower when the light-emitting diode is dimmer. In this way, due to the biological characteristics of the human visual nerve, the brightness can be perceived to change linearly and uniformly, and the light modulation effect of the light-emitting diode is improved.

[0049] In another embodiment, a luminance configuration relationship can be obtained, in which the luminance parameter gradually increases in a manner that the luminance parameter gradually increases at an increasing rate as the luminance configuration parameter decreases, and then the light-emitting diode is controlled according to the luminance configuration relationship. In this way, the luminance changes more slowly when the light-emitting diode is brighter, and the luminance changes more quickly when the light-emitting diode is dimmer. In this way, the luminance change is more easily perceived when the light-emitting diode is dimmer, and the luminance change recognition effect in this scenario is improved.

[0050] Please refer to Figure 2 In one embodiment, step 104 includes step 202 and step 204.

[0051] In step 202, the initial luminance parameter corresponding to each luminance configuration parameter in the luminance configuration range is determined according to the luminance configuration parameter and the basic luminance configuration relationship.

[0052] In step 204, an operation offset is added to the initial luminance parameter to obtain the luminance parameter corresponding to each luminance configuration parameter in the luminance configuration range.

[0053] Specifically, the non-linear dimming relationship means that the basic luminance configuration parameter and the basic luminance parameter change nonlinearly, which can be exponential change or other change trends, and the specific change trend is not limited. The linear dimming relationship means that the basic luminance parameter changes linearly following the change of the basic luminance configuration parameter. In actual scenarios, whether the linear dimming relationship or the non-linear dimming relationship, the luminance parameter corresponding to each luminance configuration parameter in the luminance configuration range can be determined in a similar manner.

[0054] The luminance configuration parameters in the luminance configuration range can be one-to-one corresponding to the basic luminance configuration parameters in the basic luminance configuration relationship, or can not be one-to-one corresponding (in which case a basic luminance configuration parameter can be mapped to each luminance configuration parameter through data interception or expansion, and the specific method is not limited).

[0055] In one embodiment, please refer to Figure 3 The basic luminance configuration parameters in the basic luminance configuration relationship include 0-31, and the corresponding luminance parameters are 129, 3-122 as shown in the figure. If the luminance configuration range also includes 32 luminance configuration parameters, such as 64-96, then the 65th luminance configuration parameter will correspond to the 1st basic luminance configuration parameter in the basic luminance configuration relationship, and the initial luminance parameter matched therewith is 3; the 66th luminance configuration parameter will correspond to the 2nd basic luminance configuration parameter in the basic luminance configuration relationship, and the initial luminance parameter matched therewith is 5. Using the above matching analysis method, the initial luminance parameter corresponding to each luminance configuration parameter in the basic luminance configuration relationship can be finally determined.

[0056] After obtaining the initial brightness parameter, considering that the brightness configuration range is not the same as the basic brightness configuration relationship starting from 0, in order to adapt the brightness parameter to the brightness configuration range at this time, an operation offset needs to be added to the initial brightness parameter, and finally the brightness parameter corresponding to different brightness configuration parameters is obtained.

[0057] The above scheme adds an operation offset to the initial brightness parameter to obtain the brightness parameter corresponding to different brightness configuration parameters, ensures the adaptability of the brightness parameter to the brightness configuration range, and improves the dimming configuration accuracy.

[0058] In one of the embodiments, the initial brightness parameter is determined according to the brightness configuration parameter and the basic brightness configuration relationship, including: determining a non-special node configuration parameter according to the brightness configuration parameter; and determining the initial brightness parameter of the non-special node configuration parameter according to the non-special node configuration parameter and the basic brightness configuration relationship.

[0059] Specifically, the special node configuration parameter is a brightness configuration parameter that needs to be configured by a method other than the above-mentioned operation offset calculation method. For the non-special node configuration parameter, the method of matching the basic brightness configuration relationship in the above-mentioned embodiment is adopted, and the operation offset is calculated to determine the brightness parameter corresponding to the non-special node configuration parameter.

[0060] The above scheme divides the brightness configuration parameter into special nodes, and the special node configuration parameter and the non-special node configuration parameter are determined by different methods, which can effectively reduce the influence of the operation offset on the brightness configuration relationship and improve the smoothness of the brightness configuration relationship.

[0061] In one of the embodiments, the method further includes: determining a special node configuration parameter according to the brightness configuration parameter; and determining the brightness parameter corresponding to the special node configuration parameter according to a preset brightness assignment parameter.

[0062] Specifically, the preset brightness assignment parameter is a preset brightness parameter required by the special node configuration parameter. In actual scenarios, the brightness parameter is assigned to some special node parts, and the brightness parameter of the remaining nodes is configured according to the operation offset, so as to form the brightness configuration relationship.

[0063] The above scheme configures the target brightness parameter for the special node configuration parameter, that is, the output target brightness parameter of part of the brightness configuration parameter is fixed-point adjusted, so that the finally output brightness configuration relationship is smoother, that is, more tends to an exponential function relationship, and the dimming effect is further improved.

[0064] It should be pointed out that the selection of the special node configuration parameter is not unique, and the brightness level or actual display requirements of the LED can be configured, and any brightness configuration parameter can be used as a special node configuration parameter, which can be configured according to actual requirements.

[0065] In one embodiment, the endpoints of the brightness configuration range can be used as special node configuration parameters. In another embodiment, the function relationship required to be satisfied in combination with the brightness configuration relationship can also be used to select the special node configuration parameter. For example, in one embodiment, the brightness parameter and the brightness configuration parameter satisfy the exponential relationship a k , a is greater than 1 (for example, 2 k ), and at this time any brightness configuration parameter that satisfies the function relationship can be used as a special node configuration parameter.

[0066] Please refer to Figure 4 In one embodiment, the initial brightness parameter is determined according to the brightness configuration parameter and the basic brightness configuration relationship, including steps 402 and 404.

[0067] Step 402: Matching according to the brightness configuration parameter and the basic brightness configuration relationship to obtain a matching brightness parameter.

[0068] Step 404: Truncating or extending the matching brightness parameter to obtain the initial brightness parameter corresponding to the brightness configuration parameter.

[0069] Specifically, the matching brightness parameter is the brightness configuration parameter mapped into the basic brightness configuration relationship, and the obtained basic brightness parameter corresponding to the brightness configuration parameter. In actual scenarios, the level of the basic brightness parameter may be different from the level of the actual required brightness parameter, for example, the basic brightness parameter in the basic brightness configuration relationship is 5 bits (including 0-31), and the actual required dimming level is 8 bits (including 0-255). Obviously, the brightness parameters of the two are not adapted to each other, and in order to realize the mapping between different brightness levels, the matching brightness parameter can be truncated or extended based on the matching brightness parameter to obtain the initial brightness parameter.

[0070] For example, in one embodiment, for the truncation operation, the bit0 of the brightness parameter can be truncated (binary), and the high bits are retained, which is equivalent to dividing the brightness parameter by 2 and taking the integer part. For the extension operation, the low bits of the brightness parameter can be supplemented with 1 bit of 0, that is, shifted to the left by 1 bit, which is equivalent to multiplying the brightness parameter by 2.

[0071] By the above scheme, the luminance parameter can be intercepted and expanded, thereby meeting the requirement of different luminance level mapping, so that multiple different luminance configuration ranges can share one basic luminance configuration relationship, and the adaptability of dimming configuration is effectively improved.

[0072] In one embodiment, the method further includes: in the case that the basic luminance configuration relationship is a linear dimming relationship, determining the luminance parameter corresponding to each luminance configuration parameter in the luminance configuration range according to the luminance configuration parameter.

[0073] Specifically, the type of the basic luminance configuration relationship is not unique, for example, the basic luminance parameter can be set as the same as the basic luminance configuration parameter, that is, the value of the luminance parameter corresponding to each basic luminance configuration parameter is the same as the basic luminance configuration parameter. In another embodiment, the basic luminance parameter can also be set as other multiples (which can be greater than 1 or less than 1) of the basic luminance configuration parameter, which can be selected according to actual scenes, and is not limited herein.

[0074] For a smaller luminance configuration parameter, since the luminance it represents is lower, the human eye is sensitive to the luminance change at this time, and only needs the luminance to change linearly, so that the human eye can feel the linear change of the luminance. Therefore, for the luminance configuration range meeting the linear dimming relationship, the luminance parameter corresponding to each luminance configuration parameter can be determined by analyzing and calculating in combination with the luminance configuration parameter.

[0075] The above scheme, for the region where the human eye is sensitive to the luminance change, determines the luminance parameter in combination with the luminance configuration parameter, obtains a linear luminance configuration relationship, and performs dimming control in this luminance interval, thereby effectively realizing that the human eye feels the linear change of the luminance.

[0076] Please refer to Figure 5 In one embodiment, step 102 includes step 502.

[0077] Step 502: determining the operation offset and the basic luminance configuration relationship according to the position of the luminance configuration range of the light-emitting diode in the overall luminance configuration range.

[0078] Specifically, the overall luminance configuration range refers to the range of the luminance configuration parameter when the LED is from off to the highest luminance, for example, it can be 0-255, 255 representing the highest luminance and 0 representing the LED being off. Due to the human eye vision characteristics, the human eye is sensitive to the luminance change when the luminance configuration parameter is low, and the human eye is not sensitive to the luminance change when the luminance configuration parameter is high, so the basic luminance configuration relationship can be determined in combination with the position of the luminance configuration range in the overall luminance configuration range.

[0079] The basic brightness configuration relationship represents the corresponding relationship between the basic brightness configuration parameter and the basic brightness parameter. The basic brightness configuration parameter usually starts from 0. When the basic brightness configuration parameter is mapped to different brightness configuration ranges, the starting point of the brightness configuration parameter will no longer be 0. The operation offset is used to connect different brightness configuration relationships, so as to form a complete relationship that the brightness parameter gradually increases with the increase of the brightness configuration parameter. Therefore, according to the position of the brightness configuration range in the overall brightness configuration range, the required operation offset is determined.

[0080] In order to facilitate understanding, a more detailed embodiment is explained below. When the brightness configuration range is in the front section (such as 0-32 or 32-64) of the overall brightness configuration range, the basic brightness configuration parameter and the basic brightness parameter are in a linear relationship, and the human eye can also recognize the linear change of the LED brightness, so the basic brightness configuration relationship can be determined as a linear dimming relationship. When the brightness configuration range is greater than 64 (such as 64-96, 96-128, etc.), the basic brightness configuration relationship can be determined as a nonlinear dimming relationship. It can be understood that one or more brightness configuration ranges can correspond to one nonlinear dimming relationship, and the specific number is not limited.

[0081] Taking the brightness configuration range 64-96 as an example, since the brightness configuration relationship is a linear dimming relationship when the brightness configuration range is 32-64, the brightness parameter is 64 when the brightness configuration parameter is 64. Correspondingly, under the basic brightness configuration relationship corresponding to the brightness configuration range 64-96, 64 can be used as the operation offset, so that the brightness configuration relationship of the brightness configuration range 64-96 is adapted to the brightness configuration relationship of the brightness configuration range 32-64.

[0082] Please refer to Figure 6 In one embodiment, the number of brightness configuration ranges is multiple, and the method further includes step 602.

[0083] Step 602, synthesizing a target brightness configuration relationship according to the brightness configuration relationship corresponding to different brightness configuration ranges.

[0084] Specifically, the target brightness configuration relationship is used for dimming control of the light-emitting diode. When the number of brightness configuration ranges is multiple, they can all be nonlinear dimming relationships, or they can include both linear dimming relationships and nonlinear dimming relationships. After obtaining the brightness configuration relationship of each brightness configuration range according to the above method, the target brightness configuration relationship can be formed by connecting the beginning and end of each brightness configuration relationship.

[0085] The above scheme uses different operation offsets and basic brightness configuration relationships in different brightness configuration ranges respectively, determines the brightness configuration relationship, synthesizes multiple brightness configuration relationships, and finally forms a target brightness configuration relationship that is smoother and closer to exponential change, and has higher dimming reliability.

[0086] It should be noted that in one embodiment, after determining the target brightness configuration relationship or the brightness configuration relationship, the control device can also perform PWM modulation according to the actual relationship to finally determine the PWM signal duty cycle corresponding to each brightness configuration parameter.

[0087] It can be understood that in one embodiment, the control device can directly perform PWM modulation according to the brightness parameters in the target brightness configuration relationship to determine the PWM signal duty cycle corresponding to each brightness configuration parameter. In another embodiment, the brightness parameters in the target brightness configuration relationship can also be truncated to finally achieve the PWM modulation effect of different bit positions, and the specific selection can be made according to actual needs.

[0088] In order to facilitate understanding of the technical solutions of the present application, the present application will be explained and described in detail below in combination with more detailed embodiments.

[0089] As shown in Figure 7 and Figure 8 , the present embodiment uses 8-bit brightness configuration (the brightness parameters include 0-255) and finally maps to 12-bit brightness configuration (the brightness parameters include 0-4095). "Segmented lookup table 1" and "segmented lookup table 2" respectively define the data content of two segmented lookup tables, that is, two basic brightness configuration relationships. The control device generates 12-bit actual effective brightness parameters BR according to the 8-bit brightness parameters. The change trend of BR is evenly divided into 8 regions with 0, 32, 64, 96, 128, 160, 192, 224, and 255 of the brightness configuration parameter BR_PRE as nodes, and each segment is defined and implemented as:

[0090] (1) When BR_PRE is 0-32 and 32-64, because the brightness is low and changes slowly, it is defined as a linear interval. At this time, the brightness parameter can be determined by combining the brightness configuration parameter, that is, the brightness configuration parameter is taken as the corresponding brightness parameter. The brightness parameter corresponding to 0 is 0, the brightness parameter corresponding to 1 is 1, …, the brightness parameter corresponding to 32 is 32, …, and the brightness parameter corresponding to 64 is 64.

[0091] (2) BR_PRE is 64-96 for a class of exponential interval 1, according to the segmented look-up table 1 to operate, BR=64+BR_LUT1[7:1], wherein, 64 represents the operation offset, and the luminance parameter corresponding to the luminance configuration parameter 64 is consistent, BR_LUT1[7:1] represents the initial luminance parameter obtained by looking up the table when the luminance configuration parameter is mapped to the basic luminance configuration parameter (0-31) in the segmented look-up table 1, and the initial luminance parameter is obtained by adding BR_LUT1[7:1] and 64, that is, the luminance parameter under the luminance configuration parameter 64-96. After fitting the luminance configuration parameter 64-96 and the obtained BR, a luminance configuration relationship (that is, the curve corresponding to a class of exponential interval 1 in the figure) can be obtained.
