[0054] This application provides a method, apparatus, electronic device, and readable storage medium for correcting button backlighting. The method applies to a button device, which includes at least one button and a button backlight fixture.

Based on the preset display brightness of each target button and the influence coefficients, the backlight fixture's display brightness is adjusted to correct the backlighting of each button. The buttons undergo backlight calibration, and the influence coefficient characterizes the effect of each button's backlight on the brightness of each button. Since a single LED in the button backlight can affect multiple buttons, the brightness of all buttons can be represented by a small number of target buttons. Therefore, the overall button backlight display can be performed based on a small number of target buttons and a small number of LEDs. Thus, even if there are a large number of buttons, the overall backlight brightness can still be set to the expected level with a small number of LEDs. This avoids the technical drawbacks of having to set the same number of LEDs when there are a large number of buttons, which would increase the number of hardware interfaces corresponding to the buttons, the power consumption of the whole machine, the battery life, and the cost. Therefore, the resource consumption of button backlight is reduced. Attached Figure Description

Obviously, for those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0057] Figure 1 This is a flowchart illustrating the first embodiment of the button backlight correction method of this application;

[0058] Figure 2 This is a schematic diagram of the device structure of the hardware operating environment involved in the button backlight correction method in this application embodiment.

[0059] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0060] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0061] Example 1

[0062] This application provides a button backlight calibration method. In the first embodiment of the button backlight calibration method of this application, refer to... Figure 1 The method is applied to a button device, the button device including at least one button and a button backlight fixture, and the button backlight calibration method includes:

[0063] Step S10: Obtain the influence coefficient of the button backlight on each button, wherein the influence coefficient is used to characterize the degree of influence of the button backlight on the display brightness of each button;

[0064] Step S20: Select at least one target button from among the buttons according to each of the influence coefficients.

[0065] Step S30: Based on the preset key display brightness corresponding to each target key and each influence coefficient, backlight correction is performed on each key by adjusting the display brightness of the key backlight lamp.

[0066] In this embodiment, it should be noted that the button device is a terminal device with button backlight display function. The button device can be a keyboard, a remote control, a game controller, or other terminal devices with button backlight display. The button backlight lamps are lamps deployed on each of the buttons for button backlighting. The display brightness of the lamps corresponding to each button backlight lamp can be the same or different. The preset button display brightness is the expected button display brightness of each target button. The preset button display brightness can be set by the user or randomly set by the system.

[0067] For example, steps S10 to S30 include: obtaining the lamp control parameters corresponding to the button backlight lamp; obtaining the influence coefficient of the button backlight lamp on each of the buttons under the lamp control parameters; selecting at least one target button among the buttons according to the influence coefficients; obtaining the preset button display brightness corresponding to each target button; and performing backlight correction on each button by adjusting the lamp display brightness of the button backlight lamp according to the preset button display brightness and the influence coefficients.

[0068] In step S10, the button backlight fixture includes at least one LED, and the step of obtaining the influence coefficient of the button backlight fixture on each button includes:

[0069] Step S11: Obtain the control parameters corresponding to each of the LED beads, and the button display brightness of each of the buttons when a single LED bead is turned on;

[0070] Step S12: Calculate the ratio between the brightness of each button and the corresponding control parameter to obtain the influence coefficient of each LED on each button.

[0071] Understandably, the brightness setting for each button is not fixed, but the number of LEDs deployed for backlighting each button in the button backlight fixture is fixed. If the number of buttons to be calibrated is less than the number of fixtures, then when the button brightness setting is low, all fixtures can be turned on, resulting in lower brightness for each fixture. Alternatively, some fixtures can be turned on, with the brightness of the already turned-on fixtures being higher than the brightness of all fixtures being on. If the number of buttons to be calibrated equals the number of fixtures, then all fixtures need to be turned on, and the control parameters for each fixture are determined by the influence coefficient.

[0072] In this embodiment, it should be noted that the LED bead is a semiconductor device for emitting light that constitutes the button backlight fixture. The LED bead can be an LED (Light Emitting Diode), an RGB LED, or an LED bead made of other materials. The control parameter is a parameter that controls the display brightness when the LED bead emits light. The control parameter can be the duty cycle of PWM (Pulse Width Modulation). The duty cycle of the PWM can be 50%, 60%, 70%, or other values.

[0073] For example, steps S11 to S12 include: obtaining control parameters corresponding to each of the LED beads; controlling each LED bead to turn on individually under its corresponding control parameters; sensing the display brightness of each LED bead when it is turned on individually by an image sensor deployed on each of the buttons; obtaining the button display brightness when each button turns on a single LED bead; wherein the image sensor can be a CCD (Charge Coupled Device) image sensor, a CMOS (Complementary Metal-Oxide-Semiconductor) image sensor, or something else; calculating the ratio between the display brightness of each button and the corresponding control parameter, and using the ratio as the influence coefficient of each LED bead on each button. For example, when the control parameter of LED bead 1 and LED bead 2 is 50, when LED bead 1 is turned on, the button brightness of button 1 is 40, and when LED bead 2 is turned on, the button brightness of button 1 is 0, then the influence coefficient of LED bead 1 on button 1 is 40 / 50, and the influence coefficient of LED bead 2 on button 1 is 0.

[0074] In step S30, the button backlight fixture includes at least one LED, and the step of adjusting the backlight brightness of the button backlight fixture to correct the backlight of each button based on the preset button display brightness of each target button and each influence coefficient includes:

[0075] Step S31: Obtain the superimposed display brightness of each target button when all the LEDs are turned on;

[0076] Step S32: Adjust the control parameters corresponding to each LED bead according to the preset display brightness of each button, the superimposed display brightness of each button, and the influence coefficient, so as to adjust the display brightness of the button backlight and perform backlight correction on each button.

[0077] In this embodiment, it should be noted that the superimposed brightness of the button display is the superposition of the designed brightness of each of the LED beads on each of the target buttons.

[0078] It is understandable that different LED beads are easily affected by engineering capabilities such as product size manufacturing tolerances, assembly tolerances, SMT mounting accuracy, and angle tolerances due to the structural components such as LED silicone and light guide film. This can easily lead to a deviation between the actual display brightness and the set brightness of a single LED bead. Consequently, when adjusting the brightness directly based on the set brightness of the LED bead, the adjustment accuracy is likely to be low, resulting in poor backlighting effect for the buttons.

[0079] To address the aforementioned deficiencies, steps S31 to S32, exemplarily, include: controlling each of the LED beads to turn on; sensing the display brightness of each target button when all LED beads are turned on using an image sensor deployed on each of the target buttons; obtaining the superimposed display brightness of each target button when all LED beads are turned on; wherein the image sensor can be a CCD image sensor or a CMOS image sensor; determining the parameter adjustment value corresponding to the control parameters of each LED bead based on the preset button display brightness, the superimposed display brightness of each button, and the influence coefficient; adjusting each control parameter according to the parameter adjustment value to adjust the display brightness of the button backlight; performing backlight correction on each button; and correcting the control parameters of the LED beads according to the preset button display brightness, thereby mapping the backlight brightness correction of the buttons to the adjustment of the control parameters of the LED beads. This avoids the technical defect of low adjustment accuracy when directly adjusting based on the set brightness of the LED beads, thus improving the backlight effect of the buttons.

[0080] As an example, step S32 includes: obtaining a preset correlation relationship, wherein the correlation relationship can be a mapping relationship and / or a correspondence relationship, the preset correlation relationship includes parameter adjustment values ​​of control parameters of each LED corresponding to each preset button display brightness, each button superimposed display brightness, and each influence coefficient; determining the parameter adjustment value corresponding to each lamp based on each preset button display brightness, each button superimposed display brightness, each influence coefficient, and the preset correlation relationship; adjusting each control parameter according to each parameter adjustment value to adjust the lamp display brightness of the button backlight lamp, and performing backlight correction on each button.

[0081] As an example, step S32 includes: obtaining a preset lamp parameter adjustment model; constructing lamp feature information corresponding to each of the preset buttons, the superimposed display brightness of each of the preset buttons, and the influence coefficients of each of the preset buttons; mapping the lamp feature information to parameter adjustment values ​​corresponding to each of the preset lamp parameters through the preset lamp parameter adjustment model; adjusting each of the control parameters according to each of the parameter adjustment values ​​to adjust the lamp display brightness of the button backlight lamp and perform backlight correction on each of the buttons.

[0082] In step S32, the step of adjusting the backlight brightness of the buttons by correcting the control parameters of each lamp based on the preset button display brightness, the superimposed button display brightness, and the influence coefficients includes:

[0083] Step A10: The difference between the display brightness of each preset button and the superimposed display brightness of the corresponding button is used as the brightness offset degree corresponding to each target button;

[0084] Step A20: Adjust the control parameters corresponding to each of the LED beads according to the brightness offset degree and the influence coefficient, so as to adjust the display brightness of the backlight of the button and perform backlight correction on each button.

[0085] In this embodiment, it should be noted that the brightness offset is the brightness offset between the target button and its corresponding preset button display brightness under the backlight of each of the LED beads.

[0086] For example, steps A10 to A20 include: calculating the difference between the display brightness of each preset button and the superimposed display brightness of the corresponding button, and using the difference as the brightness offset degree corresponding to each target button; constructing equations for each parameter adjustment value according to each brightness offset degree, each influence coefficient and the parameter adjustment value corresponding to each lamp, obtaining a system of simultaneous equations, and obtaining the parameter adjustment value corresponding to each lamp by solving the system of simultaneous equations; adjusting each control parameter according to each parameter adjustment value to adjust the lamp display brightness of the button backlight lamp, and performing backlight correction on each button.

[0087] Optionally, the step of constructing equations for each parameter adjustment value based on each brightness offset degree, each influence coefficient, and the parameter adjustment value corresponding to each lamp can specifically be as follows:

[0088] ΔY ij =A ij ΔX A +B ij ΔXB +...+N ij ΔX N

[0089] Where, ΔY ij A represents the brightness offset of the target button located in the i-th row and j-th column. ij Let B be the influence coefficient of LED A on the target button located in the i-th row and j-th column. ij Let N be the influence coefficient of LED bead B on the target button located in the i-th row and j-th column. ij Let N be the influence coefficient of LED beads on the target button located in the i-th row and j-th column, where N is the number of LED beads, and ΔX is the influence coefficient of LED beads on the target button located in the i-th row and j-th column. A ΔX is the parameter adjustment value corresponding to LED bead A. B The parameter adjustment value for LED bead B is ΔX. N This is the parameter adjustment value corresponding to LED bead N.

[0090] This application provides a method for correcting the backlight of buttons in a button device. The button device includes at least one button and a button backlight fixture. Compared to methods that use individual LEDs for backlighting each button, this application obtains an influence coefficient of the button backlight fixture on each button. This influence coefficient characterizes the degree of influence of the button backlight fixture on the display brightness of each button. Based on the influence coefficients, at least one target button is selected from the buttons. Based on the preset display brightness of each target button and the influence coefficients, the backlight fixture's display brightness is adjusted to correct the backlight brightness of each button. Backlight calibration is performed, and the influence coefficient is used to characterize the effect of each button backlight on the brightness of each button. Since a single LED in the button backlight can affect multiple buttons, the brightness of all buttons can be represented by a small number of target buttons. Therefore, the overall button backlight display can be performed based on a small number of target buttons and a small number of LEDs. Thus, even if there are a large number of buttons, the expected overall backlight brightness can still be achieved with a small number of LEDs. This avoids the technical drawbacks of having to set the same number of LEDs when there are a large number of buttons, which would increase the number of hardware interfaces corresponding to the buttons, the power consumption of the whole machine, the battery life, and the cost. Therefore, the resource consumption of button backlight is reduced.

[0091] Example 2

[0092] Furthermore, referring to Figure 2 Based on the first embodiment of this application, in another embodiment of this application, the same or similar content as in the first embodiment can be referred to the above description and will not be repeated hereafter. In addition, in step S20, the button backlight fixture includes at least one LED, and the step of selecting at least one target button among the buttons according to each influence coefficient includes:

[0093] Step S21: Obtain the number of LED beads;

[0094] Step S22: Based on the number of LED beads, each button is divided into at least one button correction area, wherein the number of button correction areas is less than or equal to the number of LED beads.

[0095] Step S23: Select at least one target button in each button correction area according to each of the influence coefficients.

[0096] It is understandable that when there are many buttons and fewer LEDs than buttons, there may be situations where the influence coefficient of each LED on a particular button is relatively small. If the initial lighting parameters are corrected based on the preset button display brightness corresponding to all buttons, it is easy to have a large number of simultaneous equations, a large amount of calculation, and a long time required to calculate the parameter adjustment values ​​corresponding to each initial lighting parameter. Furthermore, when the number of simultaneous equations is inconsistent with the number of LEDs, there may be situations where the parameter adjustment values ​​corresponding to some or all initial lighting parameters are unsolvable, resulting in low efficiency of button backlight correction or even failure to correct the button backlight.

[0097] In this embodiment, it should be noted that the key calibration area is a divided area for selecting target keys among all keys.

[0098] To overcome the above-mentioned defects, steps S21 to S23 include, for example: obtaining the number of LED beads; determining the number of regions to be divided into button correction areas based on the number of LED beads; dividing each button into at least one button correction area based on the number of regions; selecting at least one target button in each button correction area based on the influence coefficients; obtaining button correction areas by partitioning each button; and selecting target buttons in each button correction area. By representing all buttons with a small number of target buttons with larger influence coefficients, the number of simultaneous equations when calculating the parameter adjustment values ​​corresponding to each initial lamp parameter is reduced. Furthermore, the number of LED beads is consistent with the number of simultaneous equations, allowing a unique parameter adjustment value corresponding to each initial lamp parameter to be obtained by solving the simultaneous equations, thereby improving the correction efficiency and accuracy of the button backlight.

[0099] In step S22, the step of dividing each button into at least one button calibration area according to the number of LED beads includes:

[0100] Step B10: Determine the distribution of the LED beads at the positions of the LED beads in each of the buttons;

[0101] Step B20: Based on the distribution of the LED positions, the number of LEDs, and each of the influence coefficients, each button is divided into at least one button correction area.

[0102] In this embodiment, it should be noted that the distribution of the LED positions includes the positional distribution information of each LED under each button.

[0103] For example, steps B10 to B20 include: determining the lamp position distribution information of each of the lamp beads under each of the buttons, as the lamp bead position distribution of each of the lamp beads under each of the buttons; and dividing each of the buttons into at least one button correction area according to the lamp bead position distribution, the number of lamp beads and each of the influence coefficients.

[0104] In step S23, the step of selecting at least one target button in each of the button correction areas according to each of the influence coefficients includes:

[0105] Step C10: Determine the number of LED beads in each of the button calibration areas, and use the number of LED beads in each area as the number of target buttons corresponding to the target buttons in each of the button calibration areas.

[0106] Step C20: Select target buttons in each of the button calibration areas according to the influence coefficients and the number of target buttons.

[0107] In this embodiment, it should be noted that the number of LED beads in the area refers to the number of LED beads in the button calibration area.

[0108] For example, steps C10 to C20 include: determining the number of LED beads corresponding to each of the button calibration areas, and using the number of LED beads in each area as the number of target buttons corresponding to the target buttons in each of the button calibration areas; and selecting the target button number corresponding to each of the button calibration areas according to each of the influence coefficients. For example, when there is one LED bead in the first button calibration area and two LED beads in the second button calibration area, one target button is selected in the first button calibration area and two target buttons are selected in the second button calibration area.

[0109] As an example, the step of selecting the target number of target keys corresponding to the target key quantity in each of the key calibration regions according to the respective influence coefficients includes: selecting the target number of target keys corresponding to the largest influence coefficient in each of the key calibration regions.

[0110] As an example, the step of selecting the target number of target keys in each of the key calibration areas according to each of the influence coefficients includes: selecting reference keys in each of the key calibration areas whose influence coefficients are greater than a preset coefficient threshold, and randomly selecting the target number of target keys from each of the reference keys.

[0111] This application provides a method for correcting the backlight of buttons in a button device. The button device includes at least one button and a button backlight fixture. Compared to methods that use individual LEDs for backlighting each button, this application obtains an influence coefficient of the button backlight fixture on each button. This influence coefficient characterizes the degree of influence of the button backlight fixture on the display brightness of each button. Based on the influence coefficients, at least one target button is selected from the buttons. Based on the preset display brightness of each target button and the influence coefficients, the backlight fixture's display brightness is adjusted to correct the backlight brightness of each button. Backlight calibration is performed, and the influence coefficient is used to characterize the effect of each button backlight on the brightness of each button. Since a single LED in the button backlight can affect multiple buttons, the brightness of all buttons can be represented by a small number of target buttons. Therefore, the overall button backlight display can be performed based on a small number of target buttons and a small number of LEDs. Thus, even if there are a large number of buttons, the expected overall backlight brightness can still be achieved with a small number of LEDs. This avoids the technical drawbacks of having to set the same number of LEDs when there are a large number of buttons, which would increase the number of hardware interfaces corresponding to the buttons, the power consumption of the whole machine, the battery life, and the cost. Therefore, the resource consumption of button backlight is reduced.
