[0031] Embodiments of the present invention provide a display backlight stabilization method, apparatus, device, and storage medium. The display backlight stabilization method in these embodiments is applicable to displays such as PACS displays (PACS stands for Picture Archiving and Communication System), liquid crystal displays, color displays, and medical displays (such as CT, MRI, X-ray machines, MRI, endoscopy, and medical office equipment, among other applications requiring brightness stabilization).

[0032] Figure 1 FIG. 1 is a flow chart of a display backlight stabilization method provided by an embodiment of the present invention. Figure 1 As shown, the method includes the following steps S110-S150.

[0033] S110 , obtaining a backlight brightness value sequence composed of measured backlight brightness values ​​and a dimming parameter value corresponding to the backlight brightness value sequence; wherein the dimming parameter value is a pulse width modulation value or a direct current voltage value.

[0034] In this embodiment, in order to stabilize the backlight brightness of the display in a very short time and reach the optimal display usage state of the display when the display is turned on this time, it is possible to first obtain whether multiple backlight brightness values ​​have been measured in a very short time after the display is turned on this time (the very short time is a preset time threshold, such as 0.1s, 0.5s, 1s, etc., but is not limited to the above values, and the time threshold can be set according to the actual needs of the user). If multiple backlight brightness values ​​have been measured, the multiple backlight brightness values ​​that have been measured are arranged in the order of the time of acquisition to obtain a backlight brightness value sequence. Among them, each backlight brightness value in the backlight brightness value sequence corresponds to a dimming parameter value, that is, there is a mapping relationship between the dimming parameter value and the backlight brightness value (for example, there is a linear relationship between the dimming parameter value and the backlight brightness value). Afterwards, the backlight brightness value sequence and the dimming parameter value corresponding to the backlight brightness value sequence can be used as important initial parameters for quickly stabilizing the backlight brightness of the display; wherein, the dimming parameter value corresponding to the backlight brightness value sequence can be determined by the dimming parameter value corresponding to at least one backlight brightness value in the backlight brightness value sequence.

[0035] Backlight dimming methods include pulse width modulation (PWM) and direct current (DC) dimming. PWM dimming adjusts backlight brightness based on changes in the pulse width modulation (PWM) value, while DC dimming adjusts backlight brightness based on changes in the direct current (DC) voltage value. Whether PWM or DC dimming is selected, the display backlight brightness can be adjusted.

[0036] S120 , determining whether there are target end values ​​in the backlight brightness value sequence based on a preset boundary search strategy; wherein the value interval corresponding to the target end values ​​includes the preset target backlight brightness value.

[0037] In this embodiment, after the backlight brightness value sequence is acquired, a preset boundary search strategy can be used to determine and acquire the target end values ​​in the backlight brightness value sequence in order to determine whether the backlight brightness value sequence contains target end values ​​that meet the conditions. Since the target end values ​​in the backlight brightness value sequence are automatically determined and acquired based on the preset boundary search strategy, manual sequence boundary search is not required, thereby improving the efficiency of acquiring the target end values.

[0038] In one embodiment, if Figure 2 As shown, step S120 includes:

[0039] S121, acquiring backlight brightness values ​​greater than the target backlight brightness value in the backlight brightness value sequence, and forming a first backlight brightness value sequence;

[0040] S122, acquiring backlight brightness values ​​in the backlight brightness value sequence that are smaller than the target backlight brightness value, and forming a second backlight brightness value sequence;

[0041] S123: If the first backlight brightness value sequence or the second backlight brightness value sequence is an empty set, determining that target two end values ​​do not exist in the backlight brightness value sequence;

[0042] S124: If both the first backlight brightness value sequence and the second backlight brightness value sequence are not empty sets, determine whether target two end values ​​exist in the backlight brightness value sequence.

[0043] In this embodiment, when the backlight brightness value sequence is known, that is, all backlight brightness values ​​included in the backlight brightness value sequence are known, all backlight brightness values ​​greater than the target backlight brightness value can be sequentially filtered out from the backlight brightness value sequence according to the chronological order of the backlight brightness value acquisition times, and form a first backlight brightness value sequence. At the same time, all backlight brightness values ​​less than the target backlight brightness value can also be sequentially filtered out from the backlight brightness value sequence according to the chronological order of the backlight brightness value acquisition times, and form a second backlight brightness value sequence.

[0044] It can be seen that all backlight brightness values ​​in the first backlight brightness value sequence obtained must be greater than the target backlight brightness value, and all backlight brightness values ​​in the second backlight brightness value sequence obtained must be greater than the target backlight brightness value. If the first backlight brightness value sequence is an empty set, it means that all backlight brightness values ​​in the backlight brightness value sequence are less than the target backlight brightness value; if the first backlight brightness value sequence is not an empty set, it means that at least one backlight brightness value in the backlight brightness value sequence is greater than the target backlight brightness value. If the second backlight brightness value sequence is an empty set, it means that all backlight brightness values ​​in the backlight brightness value sequence are greater than the target backlight brightness value; if the second backlight brightness value sequence is not an empty set, it means that at least one backlight brightness value in the backlight brightness value sequence is less than the target backlight brightness value.

[0045] When it is determined that the first backlight brightness value sequence or the second backlight brightness value sequence is an empty set, it indicates that the target two end values ​​do not exist in the backlight brightness value sequence. Correspondingly, when it is determined that both the first backlight brightness value sequence and the second backlight brightness value sequence are not empty sets, it indicates that the target two end values ​​exist in the backlight brightness value sequence.

[0046] In one embodiment, if both the first backlight brightness value sequence and the second backlight brightness value sequence are not empty sets, after determining that target end values ​​exist in the backlight brightness value sequence, the method further includes:

[0047] Obtaining a minimum backlight brightness value in the first backlight brightness value sequence as a first endpoint value of the target two end values;

[0048] A maximum backlight brightness value in the second backlight brightness value sequence is obtained as a second endpoint value in the target two end values.

[0049] In this embodiment, the target two end values ​​can be understood as two end values ​​that are extremely close to the target backlight brightness value. If the larger value of the two end values ​​of the target (i.e., the first endpoint value) is used as the upper limit of the interval, and the smaller value of the two end values ​​of the target (i.e., the second endpoint value) is used as the lower limit of the interval, then the value interval [lower limit of the interval, upper limit of the interval] must include the target backlight brightness value; however, because the difference between the two end values ​​of the target and the target backlight brightness value exceeds the preset target difference range, any one of the two end values ​​of the target cannot be directly used as the optimal backlight brightness value of the display. It is necessary to further obtain a better dimming parameter value to control the backlight brightness value of the display to be the optimal backlight brightness value.

[0050] S130: If the target two end values ​​do not exist in the backlight brightness value sequence, the dimming parameter value is adjusted based on a preset fixed-step adjustment strategy, and a corresponding current backlight brightness value is obtained.

[0051] In this embodiment, if it is determined that the target two end values ​​do not exist in the backlight brightness value sequence, it means that all backlight brightness values ​​in the backlight brightness value sequence are greater than the target backlight brightness value or are less than the target backlight brightness value. In this case, it is necessary to quickly adjust the current dimming parameter value based on the fixed step adjustment strategy to achieve rapid adjustment of the backlight brightness value. The fixed step adjustment strategy is used to increase or decrease the dimming parameter value by a preset step size to achieve automatic adjustment of the dimming parameter value.

[0052] In one embodiment, if Figure 3 As shown, step S130 includes:

[0053] S131, obtaining the last backlight brightness value in the backlight brightness value sequence; wherein the pulse width modulation value or the DC voltage value corresponding to the last backlight brightness value is the dimming parameter value;

[0054] S132: If it is determined that the final backlight brightness value is greater than the target backlight brightness value, subtract a preset step size from the dimming parameter value to update the dimming parameter value;

[0055] S133: If it is determined that the final backlight brightness value is less than the target backlight brightness value, increase the dimming parameter value by the step size to update the dimming parameter value.

[0056] In this embodiment, the backlight brightness value at the end of the sequence of backlight brightness values ​​obtained is the most recently obtained backlight brightness value. If it is recorded as the last backlight brightness value, the pulse width modulation value or DC voltage value corresponding to the last backlight brightness value is the dimming parameter value obtained in step S110. In order to determine whether the dimming parameter value increases the step size or decreases the step size, it is necessary to first determine whether the last backlight brightness value is greater than the target backlight brightness value or less than the target backlight brightness value. When it is determined that the last backlight brightness value is greater than the target backlight brightness value, the dimming parameter value is subtracted from the step size to update the dimming parameter value; correspondingly, when it is determined that the last backlight brightness value is less than the target backlight brightness value, the dimming parameter value is increased by the step size to update the dimming parameter value. After the dimming parameter value is updated, the backlight brightness value of the display is adjusted accordingly, thereby obtaining the current backlight brightness value.

[0057] After obtaining the current backlight brightness value, it can be determined whether the difference between the current backlight brightness value and the target backlight brightness value exceeds a preset target difference range. If the difference between the current backlight brightness value and the target backlight brightness value does not exceed the target difference range, it indicates that the current backlight brightness value satisfies the conditions and no further backlight adjustment of the display is required. If the difference between the current backlight brightness value and the target backlight brightness value does not exceed the target difference range, it indicates that the current backlight brightness value does not meet the conditions and further backlight adjustment of the display is required.

[0058] S140. If it is determined that the difference between the current backlight brightness value and the target backlight brightness value exceeds a preset target difference range, the current backlight brightness value is added to the backlight brightness value sequence to update the backlight brightness value sequence, and the step of obtaining whether the target two end values ​​exist in the backlight brightness value sequence based on the preset boundary search strategy is returned to be executed.

[0059] In this embodiment, if it is determined that the difference between the current backlight brightness value and the target backlight brightness value exceeds the preset target difference range, it means that the absolute value of the difference between the current backlight brightness value and the target backlight brightness value is beyond the target difference range, indicating that the current backlight brightness value is a backlight brightness value that does not meet the conditions, and further backlight adjustment of the display is required.

[0060] Specifically, the current backlight brightness value is added to the backlight brightness value sequence to update the backlight brightness value sequence. For example, the previous backlight brightness value sequence includes N backlight brightness values ​​(N is a positive integer). At this time, after adding the current backlight brightness value to the backlight brightness value sequence, the updated backlight brightness value sequence includes N+1 backlight brightness values.

[0061] S150: If it is determined that the difference between the current backlight brightness value and the target backlight brightness value does not exceed the target difference range, control the display to display at the current backlight brightness value.

[0062] In this embodiment, if it is determined that the difference between the current backlight brightness value and the target backlight brightness value does not exceed the target difference range, it means that the current backlight brightness value is a backlight brightness value that meets the conditions, and there is no need to further adjust the backlight of the display. Directly controlling the display to display at the current backlight brightness value can achieve rapid stabilization of the backlight of the display.

[0063] In one embodiment, if Figure 4 As shown, after step S120, the following steps are further included:

[0064] S160: If target two-end values ​​exist in the backlight brightness value sequence, adjust the dimming parameter value based on a preset dynamic adjustment strategy and the target two-end values, and obtain another corresponding current backlight brightness value;

[0065] S170: If it is determined that the difference between the other current backlight brightness value and the target backlight brightness value exceeds the target difference range, then adding the other current backlight brightness value to the backlight brightness value sequence to update the backlight brightness value sequence, and returning to the step of determining whether target end values ​​exist in the backlight brightness value sequence based on the preset boundary search strategy;

[0066] S180: If it is determined that the difference between the current backlight brightness value and the target backlight brightness value does not exceed the target difference range, control the display to display at the other current backlight brightness value.

[0067] In this embodiment, if the target two-end values ​​exist in the backlight brightness value sequence, it means that the backlight brightness value sequence contains both backlight brightness values ​​greater than the target backlight brightness value and backlight brightness values ​​less than the target backlight brightness value. In this case, it is necessary to quickly adjust the dimming parameter value based on the dynamic adjustment strategy and the target two-end values. The dynamic adjustment strategy is a method of quickly finding the adjustment value of the dimming parameter value by forming a straight line equation with the backlight brightness value and the dimming parameter value.

[0068] Similarly, when another current backlight brightness value is obtained after adjusting the dimming parameter value based on the dynamic adjustment strategy and the target two end values, it can be determined whether the difference between the other current backlight brightness value and the target backlight brightness value exceeds the target difference range. If the difference between the other current backlight brightness value and the target backlight brightness value does not exceed the target difference range, it means that the other current backlight brightness value is a backlight brightness value that meets the conditions, and no further backlight adjustment of the display is required. If the difference between the other current backlight brightness value and the target backlight brightness value exceeds the target difference range, it means that the current backlight brightness value is a backlight brightness value that does not meet the conditions, and further backlight adjustment of the display is required.

[0069] As can be seen, this embodiment combines a fixed-step adjustment strategy with a dynamic adjustment strategy to quickly stabilize the display backlight. In particular, the backlight brightness can be stabilized in a very short time upon startup, thereby achieving optimal display performance. Furthermore, during long-term use, the backlight brightness of the display is monitored in real time, ensuring that the display remains stable and reliable. When searching for optimal dimming parameter values, the dimming parameter value closest to the target is found, allowing for more precise control of the display backlight brightness.

[0070] In one embodiment, if Figure 5 As shown, step S160 includes:

[0071] S161: Obtain a first endpoint value among the target two-terminal values ​​and a first dimming parameter value corresponding to the first endpoint value, and obtain a second endpoint value among the target two-terminal values ​​and a second dimming parameter value corresponding to the second endpoint value;

[0072] S162. Obtain the formula corresponding to the dynamic adjustment strategy; the formula corresponding to the dynamic adjustment strategy is expressed as: , y represents another dimming parameter value corresponding to the other current backlight brightness value, y max Indicates the first dimming parameter value, y min Indicates the second dimming parameter value, x max Indicates the first endpoint value, x min Indicates the second endpoint value, x D Indicates the target backlight brightness value;

[0073] S163: Determine the other dimming parameter value based on the first endpoint value, the first dimming parameter value, the second endpoint value, the second dimming parameter value, the target backlight brightness value, and a formula corresponding to the dynamic adjustment strategy;

[0074] S164 . Determine another current backlight brightness value corresponding to the another dimming parameter value according to a mapping relationship between the dimming parameter and the backlight brightness value.

[0075] In this embodiment, after obtaining the target two end values, the larger of the two end values ​​is used as the first endpoint value, and the smaller of the two end values ​​is used as the second endpoint value. Since the first endpoint value is also a backlight brightness value, the first dimming parameter value corresponding to the first endpoint value can be obtained based on the mapping relationship between the dimming parameter and the backlight brightness value. Similarly, the second dimming parameter value corresponding to the second endpoint value can also be obtained. After obtaining the above parameters, the formula corresponding to the dynamic adjustment strategy is obtained, and the above parameters and the target backlight brightness value are used as input parameters of the formula to calculate the other dimming parameter value.

[0076] The formula corresponding to the dynamic adjustment strategy is to form a linear equation by combining the backlight brightness value and the dimming parameter value. Based on the dynamic adjustment strategy, the adjustment value of the dimming parameter value can be quickly found.

[0077] In one embodiment, after step S163 and before step S164, the following steps are further included:

[0078] The other dimming parameter value is rounded up or rounded down to update the other dimming parameter value.

[0079] In this embodiment, after obtaining the other dimming parameter value based on the formula corresponding to the dynamic adjustment strategy, it can also be rounded up or rounded down so that it is updated to the other dimming parameter value with an integer value. The obtained other dimming parameter value is tested in the display to obtain another current backlight brightness value corresponding to the other dimming parameter value. If the difference between the other current backlight brightness value and the target backlight brightness value does not exceed the target difference range, it means that the other current backlight brightness value is a backlight brightness value that meets the conditions, and no further backlight adjustment of the display is required. If the difference between the other current backlight brightness value and the target backlight brightness value exceeds the target difference range, it means that the current backlight brightness value is a backlight brightness value that does not meet the conditions, and further backlight adjustment of the display is required.

[0080] In summary, this embodiment not only enables the display to reach the usable state as quickly as possible after being turned on, but also reduces fluctuations in the backlight brightness of the display during long-term use.

[0081] Figure 6 FIG. 1 is a schematic block diagram of a display backlight stabilization device provided by an embodiment of the present invention. Figure 6As shown, corresponding to the above display backlight stabilization method, the present invention also provides a display backlight stabilization device. The display backlight stabilization device includes a unit for executing the above display backlight stabilization method. Figure 6 The display backlight stabilization device includes: a sequence acquisition unit 110, a target end value determination unit 120, a fixed step diameter adjustment unit 130, a first stabilization control unit 140 and a second stabilization control unit 150.

[0082] The sequence acquisition unit 110 is configured to acquire a backlight brightness value sequence consisting of measured backlight brightness values ​​and a dimming parameter value corresponding to the backlight brightness value sequence; wherein the dimming parameter value is a pulse width modulation value or a DC voltage value.

[0083] In this embodiment, in order to stabilize the backlight brightness of the display in a very short time and reach the optimal display usage state of the display when the display is turned on this time, it is possible to first obtain whether multiple backlight brightness values ​​have been measured in a very short time after the display is turned on this time (the very short time is a preset time threshold, such as 0.1s, 0.5s, 1s, etc., but is not limited to the above values, and the time threshold can be set according to the actual needs of the user). If multiple backlight brightness values ​​have been measured, the multiple backlight brightness values ​​that have been measured are arranged in the order of the time of acquisition to obtain a backlight brightness value sequence. Among them, each backlight brightness value in the backlight brightness value sequence corresponds to a dimming parameter value, that is, there is a mapping relationship between the dimming parameter value and the backlight brightness value (for example, there is a linear relationship between the dimming parameter value and the backlight brightness value). Afterwards, the backlight brightness value sequence and the dimming parameter value corresponding to the backlight brightness value sequence can be used as important initial parameters for quickly stabilizing the backlight brightness of the display; wherein, the dimming parameter value corresponding to the backlight brightness value sequence can be determined by the dimming parameter value corresponding to at least one backlight brightness value in the backlight brightness value sequence.

[0084] Backlight dimming methods include pulse width modulation (PWM) and direct current (DC) dimming. PWM dimming adjusts backlight brightness based on changes in the pulse width modulation (PWM) value, while DC dimming adjusts backlight brightness based on changes in the direct current (DC) voltage value. Whether PWM or DC dimming is selected, the display backlight brightness can be adjusted.

[0085] The target two-end value determination unit 120 is used to determine whether there are target two-end values ​​in the backlight brightness value sequence based on a preset boundary search strategy; wherein the value interval corresponding to the target two-end values ​​includes the preset target backlight brightness value.

[0086] In this embodiment, after the backlight brightness value sequence is acquired, a preset boundary search strategy can be used to determine and acquire the target end values ​​in the backlight brightness value sequence in order to determine whether the backlight brightness value sequence contains target end values ​​that meet the conditions. Since the target end values ​​in the backlight brightness value sequence are automatically determined and acquired based on the preset boundary search strategy, manual sequence boundary search is not required, thereby improving the efficiency of acquiring the target end values.

[0087] In one embodiment, the target two-terminal value determination unit 120 is configured to:

[0088] Acquire backlight brightness values ​​greater than the target backlight brightness value in the backlight brightness value sequence and form a first backlight brightness value sequence;

[0089] Acquire backlight brightness values ​​in the backlight brightness value sequence that are smaller than the target backlight brightness value, and form a second backlight brightness value sequence;

[0090] If the first backlight brightness value sequence or the second backlight brightness value sequence is an empty set, determining that the target two end values ​​do not exist in the backlight brightness value sequence;

[0091] If both the first backlight brightness value sequence and the second backlight brightness value sequence are not empty sets, it is determined that target two end values ​​exist in the backlight brightness value sequence.

[0092] In this embodiment, when the backlight brightness value sequence is known, that is, all backlight brightness values ​​included in the backlight brightness value sequence are known, all backlight brightness values ​​greater than the target backlight brightness value can be sequentially filtered out from the backlight brightness value sequence according to the chronological order of the backlight brightness value acquisition times, and form a first backlight brightness value sequence. At the same time, all backlight brightness values ​​less than the target backlight brightness value can also be sequentially filtered out from the backlight brightness value sequence according to the chronological order of the backlight brightness value acquisition times, and form a second backlight brightness value sequence.

[0093] It can be seen that all backlight brightness values ​​in the first backlight brightness value sequence obtained must be greater than the target backlight brightness value, and all backlight brightness values ​​in the second backlight brightness value sequence obtained must be greater than the target backlight brightness value. If the first backlight brightness value sequence is an empty set, it means that all backlight brightness values ​​in the backlight brightness value sequence are less than the target backlight brightness value; if the first backlight brightness value sequence is not an empty set, it means that at least one backlight brightness value in the backlight brightness value sequence is greater than the target backlight brightness value. If the second backlight brightness value sequence is an empty set, it means that all backlight brightness values ​​in the backlight brightness value sequence are greater than the target backlight brightness value; if the second backlight brightness value sequence is not an empty set, it means that at least one backlight brightness value in the backlight brightness value sequence is less than the target backlight brightness value.

[0094] When it is determined that the first backlight brightness value sequence or the second backlight brightness value sequence is an empty set, it indicates that the target two end values ​​do not exist in the backlight brightness value sequence. Correspondingly, when it is determined that both the first backlight brightness value sequence and the second backlight brightness value sequence are not empty sets, it indicates that the target two end values ​​exist in the backlight brightness value sequence.

[0095] In one embodiment, if both the first backlight brightness value sequence and the second backlight brightness value sequence are not empty sets, after determining that the backlight brightness value sequence contains target two end values, the method further includes:

[0096] Obtaining a minimum backlight brightness value in the first backlight brightness value sequence as a first endpoint value of the target two end values;

[0097] A maximum backlight brightness value in the second backlight brightness value sequence is obtained as a second endpoint value in the target two end values.

[0098] In this embodiment, the target two end values ​​can be understood as two end values ​​that are extremely close to the target backlight brightness value. If the larger value of the two end values ​​of the target (i.e., the first endpoint value) is used as the upper limit of the interval, and the smaller value of the two end values ​​of the target (i.e., the second endpoint value) is used as the lower limit of the interval, then the value interval [lower limit of the interval, upper limit of the interval] must include the target backlight brightness value; however, because the difference between the two end values ​​of the target and the target backlight brightness value exceeds the preset target difference range, any one of the two end values ​​of the target cannot be directly used as the optimal backlight brightness value of the display. It is necessary to further obtain a better dimming parameter value to control the backlight brightness value of the display to be the optimal backlight brightness value.

[0099] The fixed-step adjustment unit 130 is configured to adjust the dimming parameter value based on a preset fixed-step adjustment strategy if the target two end values ​​do not exist in the backlight brightness value sequence, and obtain a corresponding current backlight brightness value.

[0100] In this embodiment, if it is determined that the target two end values ​​do not exist in the backlight brightness value sequence, it means that all backlight brightness values ​​in the backlight brightness value sequence are greater than the target backlight brightness value or are less than the target backlight brightness value. In this case, it is necessary to quickly adjust the current dimming parameter value based on the fixed step adjustment strategy to achieve rapid adjustment of the backlight brightness value. The fixed step adjustment strategy is used to increase or decrease the dimming parameter value by a preset step size to achieve automatic adjustment of the dimming parameter value.

[0101] In one embodiment, the step diameter adjustment unit 130 is specifically configured to:

[0102] Acquire the last backlight brightness value in the backlight brightness value sequence; wherein the pulse width modulation value or the DC voltage value corresponding to the last backlight brightness value is the dimming parameter value;

[0103] If it is determined that the final backlight brightness value is greater than the target backlight brightness value, subtracting a preset step size from the dimming parameter value to update the dimming parameter value;

[0104] If it is determined that the final backlight brightness value is less than the target backlight brightness value, the dimming parameter value is increased by the step size to update the dimming parameter value.

[0105] In this embodiment, the backlight brightness value ranked last in the sequence of backlight brightness values ​​obtained is the most recently obtained backlight brightness value. If it is recorded as the last backlight brightness value, the pulse width modulation value or DC voltage value corresponding to the last backlight brightness value is the dimming parameter value obtained by the sequence acquisition unit 110. In order to determine whether the dimming parameter value increases or decreases the step size, it is necessary to first determine whether the last backlight brightness value is greater than or less than the target backlight brightness value. When it is determined that the last backlight brightness value is greater than the target backlight brightness value, the dimming parameter value is subtracted from the step size to update the dimming parameter value; correspondingly, when it is determined that the last backlight brightness value is less than the target backlight brightness value, the dimming parameter value is increased by the step size to update the dimming parameter value. After the dimming parameter value is updated, the backlight brightness value of the display is adjusted accordingly, thereby obtaining the current backlight brightness value.

[0106] After obtaining the current backlight brightness value, it can be determined whether the difference between the current backlight brightness value and the target backlight brightness value exceeds a preset target difference range. If the difference between the current backlight brightness value and the target backlight brightness value does not exceed the target difference range, it indicates that the current backlight brightness value satisfies the conditions and no further backlight adjustment of the display is required. If the difference between the current backlight brightness value and the target backlight brightness value does not exceed the target difference range, it indicates that the current backlight brightness value does not meet the conditions and further backlight adjustment of the display is required.

[0107] The first stability control unit 140 is used to add the current backlight brightness value to the backlight brightness value sequence to update the backlight brightness value sequence if it is determined that the difference between the current backlight brightness value and the target backlight brightness value exceeds a preset target difference range, and return to start the target two-end value determination unit 120.

[0108] In this embodiment, if it is determined that the difference between the current backlight brightness value and the target backlight brightness value exceeds the preset target difference range, it means that the absolute value of the difference between the current backlight brightness value and the target backlight brightness value is beyond the target difference range, indicating that the current backlight brightness value is a backlight brightness value that does not meet the conditions, and further backlight adjustment of the display is required.

[0109] Specifically, the current backlight brightness value is added to the backlight brightness value sequence to update the backlight brightness value sequence. For example, the previous backlight brightness value sequence includes N backlight brightness values ​​(N is a positive integer). At this time, after adding the current backlight brightness value to the backlight brightness value sequence, the updated backlight brightness value sequence includes N+1 backlight brightness values.

[0110] The second stabilization control unit 150 is configured to control the display to display at the current backlight brightness value if it is determined that the difference between the current backlight brightness value and the target backlight brightness value does not exceed the target difference range.

[0111] In this embodiment, if it is determined that the difference between the current backlight brightness value and the target backlight brightness value does not exceed the target difference range, it means that the current backlight brightness value is a backlight brightness value that meets the conditions, and there is no need to further adjust the backlight of the display. Directly controlling the display to display at the current backlight brightness value can achieve rapid stabilization of the backlight of the display.

[0112] In one embodiment, the display backlight stabilization device further includes:

[0113] a dynamic adjustment unit, configured to adjust the dimming parameter value based on a preset dynamic adjustment strategy and the target two-end values ​​if there are target two-end values ​​in the backlight brightness value sequence, and obtain another current backlight brightness value accordingly;

[0114] a third stabilization control unit, configured to, if it is determined that the difference between the another current backlight brightness value and the target backlight brightness value exceeds the target difference range, add the another current backlight brightness value to the backlight brightness value sequence to update the backlight brightness value sequence, and return to start the target two-end value determination unit 120;

[0115] The fourth stabilization control unit is configured to control the display to display at the other current backlight brightness value if it is determined that the difference between the current backlight brightness value and the target backlight brightness value does not exceed the target difference range.

[0116] In this embodiment, if the target two-end values ​​exist in the backlight brightness value sequence, it means that the backlight brightness value sequence contains both backlight brightness values ​​greater than the target backlight brightness value and backlight brightness values ​​less than the target backlight brightness value. In this case, it is necessary to quickly adjust the dimming parameter value based on the dynamic adjustment strategy and the target two-end values. The dynamic adjustment strategy is a method of quickly finding the adjustment value of the dimming parameter value by forming a straight line equation with the backlight brightness value and the dimming parameter value.

[0117] Similarly, when another current backlight brightness value is obtained after adjusting the dimming parameter value based on the dynamic adjustment strategy and the target two end values, it can be determined whether the difference between the other current backlight brightness value and the target backlight brightness value exceeds the target difference range. If the difference between the other current backlight brightness value and the target backlight brightness value does not exceed the target difference range, it means that the other current backlight brightness value is a backlight brightness value that meets the conditions, and no further backlight adjustment of the display is required. If the difference between the other current backlight brightness value and the target backlight brightness value exceeds the target difference range, it means that the current backlight brightness value is a backlight brightness value that does not meet the conditions, and further backlight adjustment of the display is required.

[0118] It can be seen that the present embodiment combines a fixed-step adjustment strategy and a dynamic adjustment strategy, which can quickly stabilize the backlight of the display, especially when the display is turned on, the backlight brightness of the display can be stabilized in a very short time, thereby achieving the best display state of the display. Moreover, during the long-term use of the display, the backlight brightness of the display is monitored in real time to ensure that the display is always in a stable and reliable state, and when searching for the optimal dimming parameter value, the dimming parameter value closest to the target can be found, thereby more accurately controlling the backlight brightness of the display. For example, taking the application of displays in the medical field as an example, the display can maintain the consistency and stability of the brightness, better display the image information it displays, and deepen the doctor user's control over the acquisition of image information.

[0119] In one embodiment, the dynamic adjustment unit is specifically configured to:

[0120] Obtaining a first endpoint value of the target two-terminal values ​​and a first dimming parameter value corresponding to the first endpoint value, and obtaining a second endpoint value of the target two-terminal values ​​and a second dimming parameter value corresponding to the second endpoint value;

[0121] Get the formula corresponding to the dynamic adjustment strategy; the formula corresponding to the dynamic adjustment strategy is expressed as , y represents another dimming parameter value corresponding to the other current backlight brightness value, y max Indicates the first dimming parameter value, y min Indicates the second dimming parameter value, x max Indicates the first endpoint value, x min Indicates the second endpoint value, x D Indicates the target backlight brightness value;

[0122] determining the other dimming parameter value based on the first endpoint value, the first dimming parameter value, the second endpoint value, the second dimming parameter value, the target backlight brightness value, and a formula corresponding to the dynamic adjustment strategy;

[0123] According to the mapping relationship between the dimming parameter and the backlight brightness value, another current backlight brightness value corresponding to the another dimming parameter value is determined.

[0124] In this embodiment, after obtaining the target two end values, the larger of the two end values ​​is used as the first endpoint value, and the smaller of the two end values ​​is used as the second endpoint value. Since the first endpoint value is also a backlight brightness value, the first dimming parameter value corresponding to the first endpoint value can be obtained based on the mapping relationship between the dimming parameter and the backlight brightness value. Similarly, the second dimming parameter value corresponding to the second endpoint value can also be obtained. After obtaining the above parameters, the formula corresponding to the dynamic adjustment strategy is obtained, and the above parameters and the target backlight brightness value are used as input parameters of the formula to calculate the other dimming parameter value.

[0125] The formula corresponding to the dynamic adjustment strategy is to form a linear equation by combining the backlight brightness value and the dimming parameter value. Based on the dynamic adjustment strategy, the adjustment value of the dimming parameter value can be quickly found.

[0126] In one embodiment, after determining the other dimming parameter value based on the first endpoint value, the first dimming parameter value, the second endpoint value, the second dimming parameter value, the target backlight brightness value, and a formula corresponding to the dynamic adjustment strategy, the method further includes:

[0127] The other dimming parameter value is rounded up or rounded down to update the other dimming parameter value.

[0128] In this embodiment, after obtaining the other dimming parameter value based on the formula corresponding to the dynamic adjustment strategy, it can also be rounded up or rounded down so that it is updated to the other dimming parameter value with an integer value. The obtained other dimming parameter value is tested in the display to obtain another current backlight brightness value corresponding to the other dimming parameter value. If the difference between the other current backlight brightness value and the target backlight brightness value does not exceed the target difference range, it means that the other current backlight brightness value is a backlight brightness value that meets the conditions, and no further backlight adjustment of the display is required. If the difference between the other current backlight brightness value and the target backlight brightness value exceeds the target difference range, it means that the current backlight brightness value is a backlight brightness value that does not meet the conditions, and further backlight adjustment of the display is required.

[0129] In summary, this embodiment not only enables the display to reach the usable state as quickly as possible after being turned on, but also reduces fluctuations in the backlight brightness of the display during long-term use.
