However, due to the limited accuracy of these sensors, the ambient brightness values ​​they sense can fluctuate significantly when the ambient light level changes. For example, if the brightness sensor measures brightness 1 based on the current ambient light level, and then measures brightness 2 based on the next ambient light level, even though the ambient light level has not increased significantly, the difference between the two values ​​is significant. The LED screen's brightness will change significantly from 1 to 2, causing the user to experience flickering. Summary of the Invention

[0025] Example 1

[0026] Figure 1 This is a flow chart of a method for adjusting the brightness of an LED screen provided in the first embodiment of the present invention. This embodiment can be applied to a brightness adjustment device for an LED screen. The device can be implemented by software and / or hardware and can generally be integrated into an LED display. The LED display in this embodiment includes an LED screen, a brightness sensor, and a control board. The control board includes a processor. Accordingly, Figure 1 As shown, the method includes the following operations:

[0027] S110: Obtain the brightness of the current environment, and determine the first brightness that the LED screen adapts to the environment based on the current environment brightness.

[0028] In this embodiment, at least one first brightness sensor facing the environment is provided to obtain the current ambient brightness, and a first brightness adapted to the environment is determined based on the current ambient brightness. In this embodiment, an ambient brightness mapping table can be pre-established to establish a mapping relationship between ambient brightness and the corresponding optimal display brightness of the LED screen. In this embodiment, the first brightness sensor has a low sensitivity, and when the ambient light changes, the first brightness mapped to the ambient brightness obtained by the brightness sensor changes abruptly.

[0029] S120: Confirm the second brightness currently displayed on the LED screen.

[0030] In this embodiment, the brightness of the LED screen display is achieved by using a preset brightness parameter. The brightness of the LED screen display can be changed by updating the preset brightness parameter, and the second brightness currently displayed by the LED screen can be confirmed by reading the current value of the preset brightness parameter. A second brightness sensor with higher accuracy can also be provided to sense the second brightness currently displayed by the display screen. In this embodiment, the sensing accuracy of the second brightness sensor is higher than that of the first sensor.

[0031] S130. If the first brightness is equal to the second brightness, control the LED screen to maintain the second brightness; if the first brightness is different from the second brightness, control the LED screen to adjust from the second brightness to the first brightness in a preset progressive mode.

[0032] In one embodiment, when the first brightness and the second brightness are different, the preset brightness parameter is usually updated from the second brightness to the first brightness, and the driver board gradually adjusts the display brightness of the LED screen according to the updated brightness parameter so that the LED screen displays with the first brightness as the target brightness.

[0033] In one embodiment, a sliding time may be preset, and controlling the LED screen to gradually adjust from the second brightness to the first brightness in a preset manner includes controlling the LED screen to adjust from the second brightness to the first brightness within a target sliding time. In this embodiment, the sliding time may be 2-5 seconds, for example, 3 seconds.

[0034] In one embodiment, a gradual frequency may be preset, and controlling the LED screen to adjust from the second brightness to the first brightness in a preset gradual mode includes controlling the LED screen to adjust from the second brightness to the first brightness at a target gradual frequency. In this embodiment, the gradual frequency may be 30-100 times, for example, 60 times.

[0035] In one embodiment, a target sliding time and a target progressive frequency may be preset. Controlling the LED screen to gradually adjust from the second brightness to the first brightness in the preset progressive mode includes controlling the LED screen to gradually adjust from the second brightness to the first brightness at a target progressive frequency within the target sliding time. In this embodiment, the number of target progressive frequencies is much greater than the number of brightness levels between the first brightness and the second brightness.

[0036] Compared to the prior art, the brightness adjustment method for an LED screen of this embodiment obtains the brightness of the current environment, determines the first brightness of the LED screen adapted to the environment based on the current ambient brightness, determines the second brightness currently displayed by the LED screen, and if the first brightness is equal to the second brightness, controls the LED screen to maintain the second brightness; if the first brightness is different from the second brightness, controls the LED screen to adjust from the second brightness to the first brightness in a preset progressive mode. In this way, when the accuracy of the sensor is not high, resulting in a large difference between the front and back brightness adjustments, or when the ambient light changes drastically, resulting in a large difference between the front and back brightness adjustments, the LED screen automatically adjusts the brightness in accordance with the ambient light, and the change in screen brightness is also basically continuous, thereby improving the problem of brightness flickering during the brightness adjustment process of the prior art screen. In addition, because the method of this embodiment is not affected by the accuracy of the ambient light sensor, a sensor with lower accuracy can be used to detect changes in ambient light, and thus the cost of the LED display implementing the method of this case is lower.

[0037] Example 2

[0038] Figure 2 This is a flow chart of a method for adjusting the brightness of an LED screen provided in the second embodiment of the present invention. This embodiment can be applied to a brightness adjustment device for an LED screen. The device can be implemented by software and / or hardware and can generally be integrated into an LED display. The LED display in this embodiment includes an LED screen, a brightness sensor, and a control board. The control board includes a processor. Accordingly, Figure 2 As shown, the method includes the following operations:

[0039] S110: Obtain the brightness of the current environment, and determine the first brightness that the LED screen adapts to the environment based on the current environment brightness.

[0040] In this embodiment, at least one first brightness sensor facing the environment is provided to obtain the current ambient brightness, and a first brightness adapted to the environment is determined based on the current ambient brightness. In this embodiment, an ambient brightness mapping table can be pre-established to establish a mapping relationship between ambient brightness and the corresponding optimal display brightness of the LED screen. In this embodiment, the first brightness sensor has a low sensitivity, and when the ambient light changes, the first brightness mapped to the ambient brightness obtained by the brightness sensor changes abruptly.

[0041] S120: Confirm the second brightness currently displayed on the LED screen.

[0042] In this embodiment, the brightness displayed by the LED screen is achieved through preset brightness parameters. The brightness displayed by the LED screen can be changed by updating the preset brightness parameters. The second brightness currently displayed by the LED screen can be confirmed by reading the current value of the preset brightness parameters. A second brightness sensor with higher accuracy can also be set to sense the second brightness currently displayed on the display screen. In this embodiment, the sensing accuracy of the second brightness sensor is higher than the sensing accuracy of the first sensor.

[0043] S231: Determine a brightness difference between the second brightness and the first brightness.

[0044] S232: Calculate the target sliding time according to the brightness difference.

[0045] S233: Control the LED screen to adjust from the second brightness to the first brightness within the target sliding time.

[0046] In one embodiment, the target sliding time is directly proportional to the brightness difference between the second brightness and the first brightness. Specifically, if the brightness difference between the second brightness and the first brightness is large, the target sliding time is also long, for example, 4 seconds. If the brightness difference between the second brightness and the first brightness is small, the target sliding time is also short, for example, 1 second.

[0047] In one embodiment, the LED screen is controlled to adjust from the second brightness to the first brightness within the target sliding time, and the calculation is performed according to the following formula: target brightness parameter = second brightness + (current time progress / target sliding time) * (first brightness - second brightness). The target sliding time is the total duration of the adjustment from the second brightness to the first brightness; the current time progress is the progress value from 0 to the target sliding time, in milliseconds.

[0048] In one embodiment, when the first brightness and the second brightness are different, instead of directly updating the preset brightness parameter from the second brightness to the first brightness, the preset brightness parameter is updated from the second brightness to the target brightness parameter in the above formula in sequence by interpolation. The driver board gradually adjusts the display brightness of the LED screen according to the updated target brightness parameter, so that the LED screen gradually transitions from the intermediate brightness to the first brightness for display. By reasonably setting the target sliding time, the LED screen of the present application not only improves the problem of brightness flickering during the brightness adjustment process of the prior art screen, but also makes the gradual process of brightness adjustment more in line with visual habits, further enhancing the user experience.

This embodiment can be applied to a brightness adjustment device for an LED screen. The device can be implemented by software and / or hardware and can generally be integrated into an LED display. The LED display of this embodiment includes an LED screen, a brightness sensor, and a control board, and the control board includes a processor. Accordingly, Figure 3 As shown, the method includes the following operations:

[0051] S110: Obtain the brightness of the current environment, and determine the first brightness that the LED screen adapts to the environment based on the current environment brightness.

[0052] In this embodiment, at least one first brightness sensor facing the environment is provided to obtain the current ambient brightness, and a first brightness adapted to the environment is determined based on the current ambient brightness. In this embodiment, an ambient brightness mapping table can be pre-established to establish a mapping relationship between ambient brightness and the corresponding optimal display brightness of the LED screen. In this embodiment, the first brightness sensor has a low sensitivity, and when the ambient light changes, the first brightness mapped to the ambient brightness obtained by the brightness sensor changes abruptly.

[0053] S120: Confirm the second brightness currently displayed on the LED screen.

[0054] In this embodiment, the brightness of the LED screen display is achieved by using a preset brightness parameter. The brightness of the LED screen display can be changed by updating the preset brightness parameter, and the second brightness currently displayed by the LED screen can be confirmed by reading the current value of the preset brightness parameter. A second brightness sensor with higher accuracy can also be provided to sense the second brightness currently displayed by the display screen. In this embodiment, the sensing accuracy of the second brightness sensor is higher than that of the first sensor.

[0055] S331: Determine a brightness difference between the second brightness and the first brightness.

[0056] S332: Calculate the target progressive frequency according to the brightness difference.

[0057] S333: Control the LED screen to adjust from the second brightness to the first brightness at the target progressive frequency.

[0058] In one embodiment, when the first brightness and the second brightness are different, the preset brightness parameter is usually updated from the second brightness to the first brightness, and the driver board gradually adjusts the display brightness of the LED screen according to the updated brightness parameter so that the LED screen displays with the first brightness as the target brightness.

[0059] In one embodiment, the target progressive frequency is directly proportional to the brightness difference between the second brightness and the first brightness. Specifically, if the brightness difference between the second brightness and the first brightness is large, the target progressive frequency is also large, for example, 60 times. If the brightness difference between the second brightness and the first brightness is small, the target sliding time is also short, for example, 30 times.

[0060] In one embodiment, the LED screen is controlled to adjust from the second brightness to the first brightness at the target progressive frequency, which is calculated according to the following formula: target brightness parameter = second brightness + (current progressive frequency / target progressive frequency) * (first brightness - second brightness). The target progressive frequency is the total number of times the brightness is adjusted from the second brightness to the first brightness; the current progressive frequency is the number of times the brightness is adjusted from the second brightness to the first brightness.

[0061] In one embodiment, when the first brightness and the second brightness are different, instead of directly updating the preset brightness parameter from the second brightness to the first brightness, the preset brightness parameter is updated from the second brightness to the target brightness parameter in the above formula in sequence by interpolation according to the progressive frequency. The driver board gradually adjusts the display brightness of the LED screen according to the updated target brightness parameter, so that the LED screen gradually transitions from the intermediate brightness to the first brightness for display. In this embodiment, by reasonably setting the progressive frequency, the LED screen of the present application solution not only improves the problem of brightness flickering in the brightness adjustment process of the prior art screen, but also makes the progressive process of brightness adjustment more in line with visual habits, further enhancing the user experience.

[0062] Example 4

[0063] Figure 4 This is a flow chart of a method for adjusting the brightness of an LED screen provided by the fourth embodiment of the present invention. This embodiment can be applied to a brightness adjustment device for an LED screen. The device can be implemented by software and / or hardware and can generally be integrated into an LED display. The LED display of this embodiment includes an LED screen, a brightness sensor, and a control board, and the control board includes a processor. Accordingly, Figure 4 As shown, the method includes the following operations:

[0064] S110: Obtain the brightness of the current environment, and determine the first brightness that the LED screen adapts to the environment based on the current environment brightness.

[0065] In this embodiment, at least one first brightness sensor facing the environment is provided to obtain the current ambient brightness, and a first brightness adapted to the environment is determined based on the current ambient brightness. In this embodiment, an ambient brightness mapping table can be pre-established to establish a mapping relationship between ambient brightness and the corresponding optimal display brightness of the LED screen. In this embodiment, the first brightness sensor has a low sensitivity, and when the ambient light changes, the first brightness mapped to the ambient brightness obtained by the brightness sensor changes abruptly.

[0066] S120: Confirm the second brightness currently displayed on the LED screen.

[0067] In this embodiment, the brightness of the LED screen display is achieved by using a preset brightness parameter. The brightness of the LED screen display can be changed by updating the preset brightness parameter, and the second brightness currently displayed by the LED screen can be confirmed by reading the current value of the preset brightness parameter. A second brightness sensor with higher accuracy can also be provided to sense the second brightness currently displayed by the display screen. In this embodiment, the sensing accuracy of the second brightness sensor is higher than that of the first sensor.

[0068] S431: Determine a brightness difference between the second brightness and the first brightness.

[0069] S432: Determine the target sliding time and target progressive frequency according to the brightness difference.

[0070] In one embodiment, the target sliding time is directly proportional to the brightness difference between the second brightness and the first brightness. Specifically, if the brightness difference between the second brightness and the first brightness is large, the target sliding time is also longer, for example, 4 seconds. If the brightness difference between the second brightness and the first brightness is small, the target sliding time is also shorter, for example, 1 second. In this embodiment, the target progressive frequency is directly proportional to the brightness difference between the second brightness and the first brightness. Specifically, if the brightness difference between the second brightness and the first brightness is large, the target progressive frequency is also more, for example, 60 times. If the brightness difference between the second brightness and the first brightness is small, the target sliding time is also shorter, for example, 30 times.

[0071] S433: Calculate a target step interval according to the target sliding time and the target progressive frequency.

[0072] In one embodiment, the target stepping interval is calculated based on the target sliding time and the target progressive frequency using the following formula: target stepping interval = target sliding time / target progressive frequency. The target progressive frequency is the total number of times the brightness is adjusted from the second brightness to the first brightness, and the target sliding time is the total duration of the adjustment from the second brightness to the first brightness.

[0073] S434: Control the LED screen to adjust from the second brightness to the first brightness step by step at the target step interval within the target sliding time.

[0074] In one embodiment, the LED screen is controlled to gradually adjust from the second brightness to the first brightness at a target progressive frequency within a target sliding time, and is calculated according to the following formula: target brightness parameter = second brightness + (target step interval * current number of step changes / target sliding time) * (first brightness - second brightness). Wherein, the current number of step changes is the number of times the process of adjusting from the second brightness to the first brightness is currently being executed.

[0075] In one embodiment, when the first brightness and the second brightness are different, instead of directly updating the preset brightness parameter from the second brightness to the first brightness, the preset brightness parameter is updated from the second brightness to the target brightness parameter in the above formula in sequence by interpolation according to the current number of steps. The driver board gradually adjusts the display brightness of the LED screen according to the updated target brightness parameter, so that the LED screen gradually transitions from the middle brightness to the first brightness for display. In this embodiment, by reasonably setting the target sliding time and the target progressive frequency, the display brightness change of the LED screen can be adjusted in a personalized manner, which not only improves the problem of brightness flickering in the screen brightness adjustment process of the prior art, but also makes the gradual process of brightness adjustment more easily conform to the visual habits of each user, further enhancing the user experience.

[0076] In an alternative embodiment, in the process of controlling the LED screen to adjust step by step from the second brightness to the first brightness at the target step interval within the target sliding time, if the first brightness of the current environment obtained in step S110 changes, the above steps S110-S434 are re-executed with the updated first brightness to perform a new round of step-by-step brightness adjustment without waiting for the step-by-step adjustment of the previous sliding time to be fully executed. This ensures the continuity of the brightness adjustment and avoids repeated adjustment of the screen brightness caused by flickering of external ambient light.

[0077] Example 5

[0078] Figure 5 This is a schematic diagram of the structure of a brightness adjustment device for an LED screen provided by the fifth embodiment of the present invention.

[0079] The ambient brightness acquisition module 510 is used to acquire the brightness of the current environment and determine the first brightness of the LED screen adapted to the environment based on the current ambient brightness. In this embodiment, the brightness of the current environment is acquired by setting at least one first brightness sensor facing the environment, and the first brightness of the LED screen adapted to the environment is determined based on the current ambient brightness. In this embodiment, an ambient brightness mapping table can be pre-established to establish a mapping relationship between the ambient brightness and the optimal display brightness corresponding to the LED screen. In this embodiment, the first brightness sensor has a low sensitivity. When the ambient light changes, the first brightness mapped to the ambient brightness acquired by the brightness sensor changes in abrupt steps.

[0080] The screen brightness confirmation module 520 is used to confirm the second brightness currently displayed on the LED screen. In this embodiment, the brightness displayed on the LED screen is achieved by a preset brightness parameter. The brightness displayed on the LED screen can be changed by updating the preset brightness parameter, and the second brightness currently displayed on the LED screen can be confirmed by reading the current value of the preset brightness parameter. A second brightness sensor with higher accuracy can also be provided to sense the second brightness currently displayed on the display screen. In this embodiment, the sensing accuracy of the second brightness sensor is higher than that of the first sensor.

[0081] The brightness gradual adjustment module 530 is used to control the LED screen to maintain the second brightness if the first brightness is equal to the second brightness, and to control the LED screen to adjust from the second brightness to the first brightness in a preset gradual mode if the first brightness is different from the second brightness.

[0082] In one embodiment, when the first brightness and the second brightness are different, the preset brightness parameter is usually updated from the second brightness to the first brightness, and the driver board gradually adjusts the display brightness of the LED screen according to the updated brightness parameter so that the LED screen displays with the first brightness as the target brightness.

[0083] In one embodiment, the brightness gradual adjustment module 530 further includes a sliding time setting module for presetting a sliding time. The brightness gradual adjustment module 530 is configured to control the LED screen to adjust from the second brightness to the first brightness within a target sliding time according to the set sliding time. In this embodiment, the sliding time can be 2-5 seconds, for example, 3 seconds.

The brightness gradual adjustment module 530 is configured to control the LED screen to adjust from the second brightness to the first brightness according to the set target gradual frequency. In this embodiment, the gradual frequency can be 30-100 times, for example, 60 times.

[0085] In one embodiment, the brightness progressive adjustment module 530 further includes a sliding time setting module and a progressive frequency setting module. The sliding time setting module is used to preset a target sliding time; the progressive frequency setting module is used to set a target progressive frequency. The brightness progressive adjustment module 530 is used to control the LED screen to gradually adjust from the second brightness to the first brightness at a target progressive frequency within the target sliding time. In this embodiment, the number of target progressive frequencies is much greater than the number of brightness levels between the first brightness and the second brightness. For example, if the difference between the first brightness and the second brightness is 10 brightness levels, the target progressive frequency can be 20-100 times, for example, 50 times.

[0086] In this embodiment, the brightness adjustment device of the above-mentioned LED screen can execute the brightness adjustment method of the LED screen provided in any embodiment of the present invention, and has functional modules and beneficial effects corresponding to the execution method.

The device 600 can be implemented by software and / or hardware and can generally be integrated into an LED display, such as Figure 6 As shown, the device 600 includes: an environment brightness acquisition module 610, a screen brightness confirmation module 620 and a brightness gradual adjustment module 630.

[0089] The ambient brightness acquisition module 610 is used to acquire the brightness of the current environment and determine the first brightness that the LED screen adapts to the environment based on the current ambient brightness.

[0090] The screen brightness confirmation module 620 is used to confirm the second brightness currently displayed by the LED screen.

[0091] The brightness gradual adjustment module 630 is used to control the LED screen to maintain the second brightness if the first brightness is equal to the second brightness, and to control the LED screen to adjust from the second brightness to the first brightness in a preset gradual mode if the first brightness is different from the second brightness.

[0092] In one embodiment, the brightness gradual adjustment module 630 includes a brightness difference calculation module 631 , a sliding time setting module 632 , a gradual frequency setting module 633 , a step interval calculation module 634 and a step brightness control module 635 .

In one embodiment, the target sliding time is directly proportional to the brightness difference between the second brightness and the first brightness. Specifically, if the brightness difference between the second brightness and the first brightness is large, the target sliding time is also longer, for example, 4 seconds. If the brightness difference between the second brightness and the first brightness is small, the target sliding time is also shorter, for example, 1 second. In this embodiment, the target progressive frequency is directly proportional to the brightness difference between the second brightness and the first brightness. Specifically, if the brightness difference between the second brightness and the first brightness is large, the target progressive frequency is also higher, for example, 60 times. If the brightness difference between the second brightness and the first brightness is small, the target sliding time is also shorter, for example, 30 times.

[0095] The stepping interval calculation module 634 is configured to calculate a target stepping interval based on the target sliding time and target progressive frequency. Specifically, the target stepping interval can be calculated using the following formula: target stepping interval = target sliding time / target stepping frequency. The target progressive frequency is the total number of times the brightness is adjusted from the second brightness to the first brightness; the target sliding time is the total duration of the adjustment from the second brightness to the first brightness.

[0096] The step brightness control module 635 is configured to control the LED screen to gradually adjust from the second brightness to the first brightness at a target progressive frequency within a target sliding time. In this embodiment, the number of target progressive frequencies is much larger than the number of brightness levels or the brightness difference between the first brightness and the second brightness. For example, if the difference between the first brightness and the second brightness is 10 brightness levels, the target progressive frequency may be 20-100 times, for example, 60 times.

[0097] In one embodiment, the step brightness control module 635 controls the target brightness for each step according to the following formula: Target brightness parameter = second brightness + (target step interval * current step count / target sliding time) * (first brightness - second brightness). The current step count is the number of times the process of adjusting from the second brightness to the first brightness has been executed.

[0098] In an alternative embodiment, a brightness adjustment reset module is further included, which is used to, during the process of adjusting the brightness from the second brightness to the first brightness (the brightness of the LED screen is between the first brightness and the second brightness), if the first brightness of the current environment obtained by the ambient brightness acquisition module 610 changes, the brightness progressive adjustment module 630 re-executes a new round of step-by-step brightness adjustment with the updated first brightness, without waiting for the step-by-step adjustment of the last sliding time to be fully executed. This not only ensures the continuity of the brightness adjustment, but also avoids repeated adjustment of the screen brightness caused by flickering of external ambient light.

[0099] In this embodiment, the brightness adjustment device of the above-mentioned LED screen can execute the brightness adjustment method of the LED screen provided in any embodiment of the present invention, and has functional modules and beneficial effects corresponding to the execution method. For technical details that are not fully described in this embodiment, please refer to the brightness adjustment method of the LED screen provided in any embodiment of the present invention.
