Description

Technical Field

[0001] The present application relates to the technical field of backlight correction, and in particular to a key backlight correction method, device, electronic device and readable storage medium. Background Art

[0002] The lamps used for key backlighting are usually LED lamp beads. Since the LED silicone, light guide film and other structural components of LED lamp beads are extremely susceptible to engineering capabilities such as product size manufacturing tolerance, assembly tolerance, SMT attachment accuracy, and angle tolerance, it is easy for the actual display brightness of the LED lamp beads to differ significantly from their designed brightness. As a result, the backlight effect of the LED lamp beads on the keys cannot reach the set brightness of the key backlight, resulting in poor display effect of the key backlight. Summary of the Invention

[0003] The main purpose of this application is to provide a key backlight correction method, device, electronic device and readable storage medium, aiming to solve the technical problem of poor display effect of key backlight in the prior art.

[0004] To achieve the above-mentioned object, the present application provides a key backlight calibration method, which is applied to a key device, wherein the key device includes at least one key and a key backlight lamp. The key backlight calibration method includes:

[0005] Obtaining the key display brightness of each key;

[0006] Determining, based on the lamp limitation parameters corresponding to the key backlight lamps and the display brightness, the target control parameters corresponding to the key backlight lamps when each key meets the preset brightness requirement;

[0007] If the target control parameter is greater than a preset parameter threshold, at least one target lamp bead is selected from the key backlight fixture, and backlight correction is performed on each key by adjusting the display brightness of the lamp bead corresponding to the target lamp bead.

[0008] To achieve the above-mentioned objectives, the present application further provides a key backlight calibration device, which is applied to a key device, wherein the key device includes at least one key and a key backlight lamp. The key device includes at least one key and a key backlight lamp, and the key backlight calibration device includes:

[0009] An acquisition module, configured to acquire the key display brightness of each key;

[0010] a determination module, configured to determine, based on the lamp limitation parameters corresponding to the key backlight lamps and the display brightness, the target control parameters corresponding to the key backlight lamps when each key meets the preset brightness requirement;

[0011] The adjustment module is used to select at least one target lamp bead from the key backlight fixture if the target control parameter is greater than a preset parameter threshold, and perform backlight correction on each key by adjusting the lamp bead display brightness corresponding to the target lamp bead.

[0012] The present application also provides an electronic device, which includes: a memory, a processor, and a program of the key backlight correction method stored in the memory and capable of running on the processor. When the program of the key backlight correction method is executed by the processor, the steps of the key backlight correction method as described above can be implemented.

[0013] The present application also provides a computer-readable storage medium, on which is stored a program for implementing the key backlight correction method. When the program of the key backlight correction method is executed by a processor, the steps of the key backlight correction method as described above are implemented.

[0014] The present application also provides a computer program product, comprising a computer program, which implements the steps of the key backlight correction method as described above when executed by a processor.

[0015] The present application provides a key backlight correction method, device, electronic device and readable storage medium. The present application is applied to a key device, which includes at least one key and a key backlight fixture. First, the key display brightness of each key is obtained, and then the target control parameters corresponding to the key backlight fixture when each key meets the preset brightness requirement are determined based on the fixture limitation parameters corresponding to the key backlight fixture and each display brightness. Since a single lamp bead in the key backlight fixture can affect multiple keys, the display brightness of each key under the mutual influence of each lamp bead is obtained, so as to determine the target control parameters corresponding to the key backlight fixture when each key meets the corresponding preset brightness requirement. If the target control parameter is greater than the preset parameter threshold, that is, at this time the key backlight fixture cannot make all keys meet the corresponding preset brightness requirement. If all keys meet the corresponding preset brightness requirements, at least one target lamp bead is selected from the key backlight fixture, and the backlight correction of each key is performed by adjusting the lamp bead display brightness corresponding to the target lamp bead. In actual scenarios, due to the limited color perception ability of the human eye and the different sensitivities of the human eye to different colors, for example, the human eye cannot capture the slight brightness changes of other low-sensitivity colors such as blue, but is more likely to capture the slight brightness changes of other highly sensitive colors such as red. Therefore, the brightness of some target lamp beads used for backlighting keys with low-sensitivity colors can be sacrificed, so that the lamp beads other than the target lamp beads can reach their respective corresponding target key brightness, thereby maximizing the key backlight effect to reach the key backlight preset brightness, thereby improving the display effect of the key backlight.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0024] Example 1

[0025] The present application embodiment provides a key backlight correction method. In the first embodiment of the key backlight correction method of the present application, refer to Figure 1 , applied to a key device, the key device including at least one key and a key backlight lamp, the key backlight correction method comprising:

[0026] Step S10, obtaining the key display brightness of each key;

[0027] In this embodiment, it should be noted that the button device is a terminal device with a button backlight display function. The button device can be a keyboard, a remote control, or other terminal devices with a button backlight display, such as a game controller. The button backlight lamp is a lamp deployed on each of the buttons for button backlighting.

[0028] Exemplarily, step S10 includes: turning on the key backlight lamp, and acquiring the key display brightness of each key when the key backlight lamp is turned on.

[0029] As an example, step S10 includes: sensing the key display brightness of each key when the key backlight is turned on through an image sensor deployed on each key, wherein the image sensor can be a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal-Oxide-Semiconductor) image sensor.

[0030] Step S20, determining a target control parameter corresponding to the key backlight lamp when each key meets a preset brightness requirement based on the lamp limitation parameter corresponding to the key backlight lamp and each display brightness;

[0031] Step S30: If the target control parameter is greater than a preset parameter threshold, at least one target lamp bead is selected from the key backlight fixture, and backlight correction is performed on each key by adjusting the display brightness of the lamp bead corresponding to the target lamp bead.

[0032] In this embodiment, it should be noted that the lamp beads are semiconductor devices used to emit light and constitute the key backlight fixture. The lamp beads may be LED (Light Emitting Diode) lamp beads, RGB lamp beads, or lamp beads made of other materials. The lamp bead control parameter is a parameter that controls the display brightness of the lamp bead when emitting light. The lamp bead control parameter may be a PWM (Pulse Width Modulation) duty cycle. The PWM duty cycle may be 50, 60, 70, or other values between 0 and 100. The display brightness of each lamp bead in the key backlight fixture may be consistent or inconsistent. The lamp limit parameter is a lamp control parameter threshold value of the key backlight fixture. The lamp limit parameter may be a lamp control parameter threshold value corresponding to each lamp bead constituting the key backlight fixture. The preset parameter threshold value is a preset control parameter threshold value corresponding to the key backlight fixture. The preset parameter threshold value may be the sum of the lamp control parameter threshold values corresponding to all lamp bead constituting the key backlight fixture.

[0033] Exemplarily, steps S20 to S30 include: determining the target control parameters corresponding to the key backlight fixtures when each of the keys meets the preset brightness requirements based on the lamp limitation parameters corresponding to the key backlight fixtures and the display brightness of each of the keys; judging whether the target control parameters are greater than the preset parameter threshold, and if the target control parameters are greater than the preset parameter threshold, selecting at least one target lamp bead from the key backlight fixtures, and performing backlight correction on each of the keys by adjusting the lamp bead display brightness corresponding to the target lamp bead; if the target control parameter is less than or equal to the preset parameter threshold, performing backlight correction on each of the keys by adjusting the lamp control parameters corresponding to the key backlight fixtures to the target control parameters.

[0034] The keys include at least one white key, the key backlight fixture includes at least one first lamp bead for backlighting each of the white keys, the lamp restriction parameter includes a first lamp bead restriction parameter corresponding to the first lamp bead, the target control parameter includes a first control parameter corresponding to each of the first lamp beads, and the display brightness includes a white key display brightness corresponding to each of the white keys. In step S20, the step of determining, based on the lamp restriction parameter corresponding to the key backlight fixture and each of the display brightnesses, the target control parameter corresponding to the key backlight fixture when each of the keys meets the preset brightness requirement includes:

[0035] Step A10, determining the upper limit of the white key brightness and the lower limit of the white key brightness corresponding to each white key according to the preset brightness requirement;

[0036] Step A20: Determine, based on the display brightness of each white button, the upper limit parameter and the lower limit parameter of the first lamp bead corresponding to each white button, wherein the upper limit parameter of the first lamp bead is the upper limit parameter corresponding to the first lamp bead of each white button at the upper limit of the white button brightness, and the lower limit parameter of the first lamp bead is the lower limit parameter corresponding to the first lamp bead of each white button at the lower limit of the white button brightness;

[0037] Step A30: Select the first control parameter from the preset first control parameter corresponding to the preset white button display brightness and the first lamp bead limiting parameter according to the first lamp bead upper limit parameter and the first lamp bead lower limit parameter.

[0038] In this embodiment, it should be noted that the number of the first lamp beads can be one or more. The preset brightness requirement is the preset achievable brightness range corresponding to each of the buttons, the upper limit of the white button brightness is the maximum brightness that the white button can display, and the lower limit of the white button brightness is the minimum brightness that the white button can display. The preset white button display brightness is the preset expected display brightness of the white button, and the preset white button display brightness may or may not fall within the preset brightness requirement. The first lamp bead restriction parameter is the sum of the lamp bead restriction parameters corresponding to all the first lamp beads.

[0039] Exemplarily, steps A10 to A30 include: using the upper limit value of the achievable brightness range corresponding to the white button in the preset brightness requirement as the upper limit of the white button brightness corresponding to each of the white buttons, and using the lower limit value of the achievable brightness range corresponding to the white button in the preset brightness requirement as the lower limit of the white button brightness corresponding to each of the white buttons; integrating the display brightness of each of the white buttons into the total brightness of the white buttons corresponding to each of the white buttons, obtaining the total control parameters of the first lamp beads corresponding to each of the first lamp beads under the total brightness of the white buttons, and generating the average brightness coefficient corresponding to the white buttons according to the total brightness of the white buttons and the total control parameters of the first lamp beads; determining the brightness of each of the white buttons under the upper limit of the white button brightness according to the average brightness coefficient and the upper limit of the white button brightness. The first lamp bead upper limit parameter corresponding to the first lamp bead; determine the first lamp bead lower limit parameter corresponding to each of the white buttons at the white button brightness lower limit according to the average brightness coefficient and the white button brightness lower limit; obtain the white button display control parameters corresponding to the first lamp bead of each of the white buttons at the white button display brightness, and the white button average display control parameters corresponding to each of the white button display control parameters, determine the preset first control parameters corresponding to the first lamp bead of the white button at the preset white button display brightness according to the white button display control parameters and the white button average display control parameters, and select the first control parameter from the preset first control parameters and the first lamp bead limit parameters according to the first lamp bead upper limit parameter and the first lamp bead lower limit parameter.

[0040] Optionally, the step of generating an average brightness coefficient corresponding to the white button according to the total brightness of the white button and the total control parameter of the first lamp bead may specifically be:

[0041]

[0042] Among them, Coef1 is the average brightness coefficient corresponding to the white key, BW1 is the total brightness of the white key, PWM T1 is the total control parameter of the first lamp bead.

[0046] Optionally, the step of determining, based on the average brightness coefficient and the lower limit of the white key brightness, a first lamp bead lower limit parameter corresponding to the first lamp bead of each white key under the lower limit of the white key brightness includes:

[0047]

[0048] Among them, Coef1 is the average brightness coefficient corresponding to the white button, BW L is the lower limit of the brightness of the white button, and PWM2 is the lower limit parameter of the first lamp bead.

[0049] Optionally, the step of determining a preset first control parameter corresponding to the first lamp bead of the white button at a preset white button display brightness according to the white button display control parameter and the white button average display control parameter includes:

[0050]

[0051] Among them, PWM3 is the preset first control parameter, BW c Display brightness of the preset white button, BW T Display control parameters for the white buttons. The control parameters are displayed averagely for the white buttons.

[0052] It is understandable that in actual scenarios, the first control parameter corresponding to the first lamp bead used to backlight the white key may not meet the expected display brightness of the white key, that is, the first control parameter limit is less than the expected lamp bead control parameter corresponding to the expected display brightness of the white key. Therefore, according to the first lamp bead limit parameter and the first lamp bead upper limit parameter, the first control parameter corresponding to each first lamp bead is determined and adjusted, so that the white key meets the preset white key display brightness while trying not to exceed the lamp bead control parameter limit corresponding to the first lamp bead.

[0053] The step of selecting the first control parameter from the preset first control parameter corresponding to the preset white button display brightness and the first lamp bead limit parameter according to the first lamp bead upper limit parameter and the first lamp bead lower limit parameter includes:

[0054] Step A31: If the first lamp bead limiting parameter is greater than the first lamp bead upper limit parameter, then selecting the preset control parameter corresponding to the preset white button display brightness as the first control parameter;

[0055] Step A32: If the first lamp bead limit parameter is less than or equal to the first lamp bead upper limit parameter, and the first lamp bead limit parameter is greater than or equal to the first lamp bead lower limit parameter, the first lamp bead limit parameter is selected as the first control parameter.

[0056] Exemplarily, steps A31 to A32 include: if the first lamp bead limitation parameter is greater than the first lamp bead upper limit parameter, then selecting the preset control parameter corresponding to the preset white button display brightness as the first control parameter; if the first lamp bead limitation parameter is less than or equal to the first lamp bead upper limit parameter, and the first lamp bead limitation parameter is greater than or equal to the first lamp bead lower limit parameter, then selecting the first lamp bead limitation parameter as the first control parameter; if the first lamp bead limitation parameter is less than the first lamp bead lower limit parameter, then determining that the brightness of the first lamp bead product is unqualified, and replacing the first lamp bead.

[0057] The keys further include at least one color key, the key backlight fixture further includes at least one second lamp bead for backlighting each of the color keys, the lamp restriction parameter further includes an upper limit of a lamp bead restriction parameter corresponding to both the first lamp bead and the second lamp bead for backlighting the white key, the target control parameter further includes a second control parameter corresponding to each of the second lamp beads, and the display brightness further includes a color key display brightness corresponding to each of the color keys. In step S20, the step of determining, based on the lamp restriction parameter corresponding to the key backlight fixture and each of the display brightnesses, the target control parameter corresponding to the key backlight fixture when each of the keys meets the preset brightness requirement further includes:

[0058] Step B10, determining the upper limit of the color key brightness corresponding to each color key and the lower limit of the color key brightness corresponding to each color key according to the preset brightness requirement;

[0059] Step B20: determining a target parameter adjustment multiple corresponding to each second lamp bead according to the color button display brightness, the upper limit value of the lamp bead limit parameter, the upper limit of the color button brightness, and the lower limit of the color button brightness;

[0060] Step B30: Adjust the lamp bead control parameter corresponding to the second lamp bead according to the target parameter adjustment multiple to obtain the second control parameter.

[0061] In this embodiment, it should be noted that the number of second lamp beads can be one or more. The upper limit of the color key brightness is the maximum brightness that the color key can display, and the lower limit of the color key brightness is the minimum brightness that the color key can display. The preset color key display brightness is the preset expected display brightness of the color key. The upper limit of the lamp bead limit parameter is the minimum value of the lamp bead limit parameter corresponding to all the first lamp beads and all the second lamp beads.

[0062] Exemplarily, steps B10 to B30 include: using the upper limit value of the achievable brightness range corresponding to the color key in the preset brightness requirement as the upper limit of the color key brightness corresponding to each color key, and using the lower limit value of the achievable brightness range corresponding to the color key in the preset brightness requirement as the lower limit of the color key brightness corresponding to each color key; determining the target parameter adjustment multiple corresponding to each second lamp bead based on the color key display brightness, the upper limit value of the lamp bead limitation parameter, the upper limit of the color key brightness and the lower limit of the color key brightness; and using the product of the lamp bead control parameter corresponding to the second lamp bead and the target parameter adjustment multiple as the second control parameter.

[0063] Among them, in step B30, the step of determining the target parameter adjustment multiple corresponding to each second lamp bead according to the color button display brightness, the upper limit value of the lamp bead limit parameter, the upper limit of the color button brightness, and the lower limit of the color button brightness includes:

[0064] Step B31: Determine, based on the color key display brightness and the upper limit value of the lamp bead limiting parameter, the first parameter adjustment multiple, the second parameter adjustment multiple, and the third parameter adjustment multiple corresponding to each second lamp bead, wherein the first parameter adjustment multiple is used to adjust the control parameter corresponding to the second lamp bead to adjust the color key from the color key display brightness to the preset color key display brightness, the second parameter adjustment multiple is used to adjust the control parameter corresponding to the second lamp bead to adjust the color key from the color key display brightness to the color key brightness upper limit, and the third parameter adjustment multiple is used to adjust the control parameter corresponding to the second lamp bead to adjust the color key from the color key display brightness to the color key brightness lower limit;

If the second parameter adjustment multiple is greater than or equal to the parameter adjustment multiple threshold, adjust the second parameter adjustment multiple to the parameter adjustment multiple threshold; if the second parameter adjustment multiple is less than the parameter adjustment multiple threshold, do not adjust the second parameter adjustment multiple;According to the lower limit of the color key brightness and the display brightness of the second color key, determine the third parameter adjustment multiple corresponding to the second backlight lamp bead to adjust the second color key from the second color key display brightness to the lower limit of the color key brightness, judge whether the third parameter adjustment multiple is greater than or equal to the parameter adjustment multiple threshold, if the third parameter adjustment multiple is greater than or equal to the parameter adjustment multiple threshold, adjust the third parameter adjustment multiple to the parameter adjustment multiple threshold, if the third parameter adjustment multiple is less than the parameter adjustment multiple threshold, do not adjust the third parameter adjustment multiple; judge whether the first parameter adjustment multiple is less than is greater than or equal to the third parameter adjustment factor, and if the first parameter adjustment factor is less than or equal to the third parameter adjustment factor, the third parameter adjustment factor is used as the target parameter adjustment factor; if the first parameter adjustment factor is greater than the third parameter adjustment factor, it is determined whether the first parameter adjustment factor is less than or equal to the second parameter adjustment factor, and if the first parameter adjustment factor is less than or equal to the second parameter adjustment factor, the second parameter adjustment factor is used as the target parameter adjustment factor; if the first parameter adjustment factor is greater than the second parameter adjustment factor, the first parameter adjustment factor is used as the target parameter adjustment factor.

[0080] An embodiment of the present application provides a key backlight correction method, which is applied to a key device, wherein the key device includes at least one key and a key backlight fixture. First, the key display brightness of each key is obtained, and then the target control parameter corresponding to the key backlight fixture when each key meets the preset brightness requirement is determined according to the fixture limitation parameter corresponding to the key backlight fixture and each display brightness. Since a single lamp bead in the key backlight fixture can affect multiple keys, the display brightness of each key under the mutual influence of each lamp bead is obtained, so as to determine the target control parameter corresponding to the key backlight fixture when each key meets the corresponding preset brightness requirement. If the target control parameter is greater than the preset parameter threshold, that is, at this time, the key backlight fixture cannot make all keys reach the target control parameter. To meet the corresponding preset brightness requirement, at least one target lamp bead is selected from the key backlight lamp fixture, and the backlight correction of each key is performed by adjusting the lamp bead display brightness corresponding to the target lamp bead. In actual scenarios, due to the limited color perception ability of the human eye and the different sensitivities of the human eye to different colors, for example, the human eye cannot capture the slight brightness changes of other low-sensitivity colors such as blue, but is more likely to capture the slight brightness changes of other highly sensitive colors such as red. Therefore, the brightness of some target lamp beads used for backlighting keys with low-sensitivity colors can be sacrificed, so that the other lamp beads except the target lamp beads can reach their respective corresponding target key brightness, thereby maximizing the key backlight effect to reach the key backlight preset brightness, thereby improving the display effect of the key backlight.

[0081] Example 2

[0082] Further, refer to Figure 2 Based on the first embodiment of the present application, in another embodiment of the present application, the same or similar contents as those in the above-mentioned first embodiment can be referred to the above introduction and will not be described in detail later. On this basis, wherein the target lamp bead includes a target first lamp bead selected from the first lamp bead used to backlight the white key, in step S40, adjusting the display brightness of the lamp bead corresponding to the target lamp bead includes:

[0083] Step C10, obtaining the design margin corresponding to the target first lamp bead;

[0084] Step C20, adjusting the display brightness of the lamp bead corresponding to the target first lamp bead by adjusting the first target control parameter corresponding to the target first lamp bead according to the design margin and the lower limit of the white button brightness corresponding to the white button.

[0085] Optionally, the step of adjusting the first target control parameter corresponding to the target first lamp bead according to the design margin and the lower limit of the white button brightness corresponding to the white button may specifically be:

[0086]

[0087] Among them, PWm T2 is the target value after the adjustment of the first control parameter, PWM M1 is the first target control parameter corresponding to the first target lamp bead, BW L is the lower limit of the brightness of the white key, r is the design margin, and the design margin can be 95%.

[0088] Wherein, the target lamp bead includes a target second lamp bead selected from the second lamp bead used for backlighting the color key. In step S40, adjusting the display brightness of the lamp bead corresponding to the target lamp bead also includes:

[0089] Step D10, obtaining a parameter difference between the target control parameter and the preset parameter threshold;

[0090] Step D20: adjusting the second target control parameter corresponding to the target second lamp bead according to the parameter difference.

[0091] Exemplarily, steps D10 to D20 include: obtaining the parameter difference between the target control parameter and the preset parameter threshold and the current total display brightness of the second lamp bead corresponding to the target second lamp bead under the color button display brightness of all color buttons; determining the control parameter adjustment ratio corresponding to the target second lamp bead based on the parameter difference and the current total display brightness of the second lamp bead; adjusting the second target control parameter corresponding to the target second lamp bead according to the control parameter adjustment ratio, specifically, adjusting the second target control parameter corresponding to the target second lamp bead to the product of the second target control parameter and the control parameter adjustment ratio.

[0092] Optionally, the step of obtaining a parameter difference between the target control parameter and the preset parameter threshold may specifically be:

[0093] Δ=PWM T3 -PWM Max

[0094] Wherein, Δ is the parameter difference, PWM T3 is the target control parameter, PWM Max is the preset parameter threshold.

[0095] Optionally, the step of determining the control parameter adjustment ratio corresponding to the target second lamp bead according to the parameter difference and the current total display brightness of the color key may specifically be:

[0096]

[0097] Wherein, s is the control parameter adjustment ratio, PWM T3 is the total display brightness of the current second lamp bead, and Δ is the parameter difference.

[0098] It is understandable that the execution order of the above steps C10 to C20 and the above steps D10 to D20 is not fixed. However, due to the limited color perception ability of the human eye, the human eye is less sensitive to white than to color. Therefore, the first control parameter corresponding to the first lamp bead used to backlight the white key can be adjusted first. After the adjustment, if the target control parameter is still greater than the preset parameter threshold, the second lamp bead control parameter corresponding to the second lamp bead used to backlight the color key can be adjusted. When the user has a color discrimination-related disease such as color blindness or color weakness, the user's sensitivity to all colors is low, or the sensitivity to colors with a higher conventional sensitivity (for example, red) is low. Therefore, in addition to the above order, the second lamp bead control parameter can be adjusted first. After the adjustment, if the target control parameter is still greater than the preset parameter threshold, the first control parameter can be adjusted.

[0099] Optionally, before the step of obtaining the parameter difference between the target control parameter and the preset parameter threshold, the method further includes:

[0100] Obtain the user's color preference for each color key, generate the priority corresponding to each color key according to each color preference degree, select the target color key whose priority is less than a preset priority threshold among the color keys, wherein the preset priority threshold is a pre-set priority critical value for determining a lower priority, and use the second lamp bead corresponding to the target color key as the target second lamp bead.

[0101] As an example, corporate culture information corresponding to the corporate culture is obtained, and the priority corresponding to each color button is generated according to the corporate culture information. For example, if the corporate culture information is a sun symbol, colors such as red and orange are set to a higher priority, and other colors not related to the sun symbol are set to a lower priority.

[0102] By sacrificing the brightness of the keys corresponding to colors that are less preferred by users, the target control parameter corresponding to the key backlight fixture is made less than or equal to the preset parameter threshold, thereby ensuring that the key backlight effect meets user expectations to the greatest extent and improving the display effect of the key backlight.

[0103] Optionally, after the step of adjusting the second target control parameter corresponding to the target second lamp bead according to the parameter difference, the method further includes:

[0104] If the target control parameter is still greater than the preset parameter threshold, lower the preset priority threshold and return to the execution step: select the target color key whose priority is less than the preset priority threshold from each color key until the target control parameter is less than or equal to the preset parameter threshold.

[0105] Optionally, after the step of setting the target control parameter to be less than or equal to a preset parameter threshold, the method further includes:

[0106] Obtain an influence coefficient of the key backlight fixture on each of the white keys, wherein the influence coefficient is used to characterize the degree of influence of the key backlight fixture on the display brightness of each white key; based on each of the influence coefficients, select at least one target white key from each of the white keys; and perform backlight correction on each of the target white keys by adjusting the lamp display brightness of the key backlight fixture based on the preset key display brightness of each target key and each of the influence coefficients.

[0107] It is understandable that since a single lamp bead in the key backlight fixture can affect multiple keys, a small number of target white keys can be used to represent the brightness of all white keys, and then the overall white key backlight display can be performed based on a small number of target white keys and a small number of lamp beads. Therefore, even if the number of keys is large, the overall white key backlight brightness setting expectation can still be achieved through a small number of lamp beads, avoiding the need to set the same number of LED lamp beads when the number of keys is large, thereby reducing the number of hardware interfaces corresponding to the keys, the power consumption of the entire machine, the battery life, and the technical defects of higher costs, thereby reducing the resource loss of the key backlight.

[0108] An embodiment of the present application provides a key backlight correction method, which is applied to a key device, wherein the key device includes at least one key and a key backlight fixture. First, the key display brightness of each key is obtained, and then the target control parameter corresponding to the key backlight fixture when each key meets the preset brightness requirement is determined according to the fixture limitation parameter corresponding to the key backlight fixture and each display brightness. Since a single lamp bead in the key backlight fixture can affect multiple keys, the display brightness of each key under the mutual influence of each lamp bead is obtained, so as to determine the target control parameter corresponding to the key backlight fixture when each key meets the corresponding preset brightness requirement. If the target control parameter is greater than the preset parameter threshold, that is, at this time, the key backlight fixture cannot make all keys reach the target control parameter. To meet the corresponding preset brightness requirement, at least one target lamp bead is selected from the key backlight lamp fixture, and the backlight correction of each key is performed by adjusting the lamp bead display brightness corresponding to the target lamp bead. In actual scenarios, due to the limited color perception ability of the human eye and the different sensitivities of the human eye to different colors, for example, the human eye cannot capture the slight brightness changes of other low-sensitivity colors such as blue, but is more likely to capture the slight brightness changes of other highly sensitive colors such as red. Therefore, the brightness of some target lamp beads used for backlighting keys with low-sensitivity colors can be sacrificed, so that the other lamp beads except the target lamp beads can reach their respective corresponding target key brightness, thereby maximizing the key backlight effect to reach the key backlight preset brightness, thereby improving the display effect of the key backlight.
