[0052] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a microprocessor, etc. The following takes a microprocessor as an example to illustrate this embodiment and the following embodiments.

[0053] Based on this, the embodiment of the present application provides a brightness adjustment method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the brightness adjustment method of the present application.

[0054] In this embodiment, the brightness adjustment method includes steps S10 to S30:

[0055] Step S10, when the current environment brightness is greater than a preset brightness threshold, determining a target brightness of the display device according to the current environment brightness.

[0056] It should be noted that when it is determined that the current environment brightness is greater than the preset brightness threshold, it indicates that the current environment brightness is high, and the brightness of the display device needs to be adjusted. When it is determined that the current environment brightness is less than or equal to the preset brightness threshold, the process of adjusting the brightness of the display device is not executed. The current environment brightness can be identified by the sensing module.

[0057] It should be understood that the target brightness refers to the optimal brightness of the display device in the current environment, and there is a corresponding relationship between the brightness of the display device and the ambient brightness. For example, when the current ambient brightness is a1, the corresponding target brightness of the display device is b1, and when the current ambient brightness is a2, the corresponding target brightness of the display device is b2. In addition, the display device can be a large display screen used outdoors, and multiple light sources are arranged inside the large display screen.

[0058] Step S20, determining a target relative position between a light-transmitting area and a corresponding light-impermeable area of ​​the multi-layer shading plate according to the target brightness.

[0059] It is understandable that for each layer of the shading plate, including the light-transmitting area and the light-impermeable area, refer to Figure 2 , Figure 2 It is a schematic diagram of the shading plate area, specifically: the pure gray part represents the opaque area, the white part represents the translucent area, the slash gray part represents the target traction device of the shading plate, and takes two layers of shading plates as an example for explanation, namely shading plate M and shading plate N, wherein the translucent area of ​​shading plate M can be the area in the set of translucent areas that is closest to the target traction device of the shading plate, and the corresponding opaque area can be the area in the set of opaque areas of shading plate N that is closest to the target traction device of the shading plate.

[0060] It should be noted that the target relative position refers to the relative position between the light-transmitting area of ​​the multi-layer shading plate and the corresponding light-impermeable area. When the light-transmitting area of ​​the multi-layer shading plate and the corresponding light-impermeable area are at the target relative position, the brightness of the display device is the target brightness, that is, adapted to the ambient brightness. In addition, when the ambient brightness changes, the microprocessor will also control the target traction device of the shading plate, and adjust the brightness of the display device again by adjusting the relative position between the light-transmitting area of ​​the multi-layer shading plate and the corresponding light-impermeable area.

[0061] Step S30, adjusting the brightness of the display device according to the relative position of the target through the target traction device of the shading plate.

[0062] It should be understood that the target traction device of the shading plate refers to a device used to adjust the relative position between the light-transmitting area and the corresponding light-impermeable area of ​​the multi-layer shading plate, and the target traction device of the shading plate includes but is not limited to a motor reel, an adjustment module, etc., wherein the motor reel is used to pull the adjustment module, and during the traction process, the light-transmitting area of ​​the shading plate M or the corresponding light-impermeable area of ​​the shading plate N will move accordingly, thereby achieving the purpose of adjusting the brightness of the display device.

[0063] Further, step S30 includes: calculating the relative position difference between the target relative position and the current relative position; obtaining a single position adjustment distance of the target traction device of the shading plate; calculating the position adjustment time according to the single position adjustment distance and the relative position difference; when controlling the target traction device of the shading plate to adjust the relative position between the light-transmitting area and the corresponding light-impermeable area of ​​the multi-layer shading plate, counting the adjustment time; when the adjustment time reaches the position adjustment time, completing the adjustment of the brightness of the display device.

[0064] It can be understood that the relative position difference refers to the difference between the target relative position and the current relative position. The larger the difference is, the longer the adjustment time is required. The single position adjustment distance refers to the distance that the target traction device controlling the sunshade is adjusted once per unit time. The specific method for calculating the position adjustment time is:

[0065]

[0066] Wherein, t represents the position adjustment time, l represents the relative position difference, and s represents the distance of a single position adjustment.

[0067] It should be understood that after calculating the position adjustment time, the target traction device of the shading plate will be controlled to start running, that is, to adjust the relative position between the light-transmitting area and the corresponding light-impermeable area of ​​the multi-layer shading plate, and use the adjustment time as an indicator to determine whether it is adjusted to the target relative position, that is, to judge whether the adjustment time reaches the position adjustment time. If so, it indicates that the adjustment has been completed. At this time, the blocking area between the light-transmitting area and the corresponding light-impermeable area will change, thereby realizing the adjustment of the brightness of the display device. For example, the brightness of the display device is 50% before adjustment, and the brightness of the display device is 80% after adjustment.

[0068] Furthermore, after step S30, it also includes: obtaining the brightness of the adjusted display device; when the brightness of the adjusted display device is the target brightness, generating a brightness adjustment strategy; based on the brightness adjustment strategy, adjusting the brightness of other display devices according to the light-transmitting areas and corresponding light-impermeable areas of the multi-layer shading plate.

[0069] It should be understood that when it is determined that the brightness of the adjusted display device is the target brightness, it indicates that the brightness of the adjusted display device is adapted to the ambient brightness, and a brightness adjustment strategy is generated at this time, wherein the brightness adjustment strategy refers to a strategy for efficiently adjusting the brightness of a large display screen. If the current application scenario is that there are multiple display devices that need to be adjusted, after adjusting the brightness of the display device, the brightness adjustment strategy is adopted to adjust the brightness of other display devices according to the light-transmitting area of ​​the multi-layer shading plate and the corresponding light-impermeable area until the brightness of all display devices is fully adjusted.

[0070] Furthermore, after the step of adjusting the brightness of the display device according to the target relative position by the target traction device through the shading plate, the step also includes: displaying a brightness input box when a brightness input request is received; obtaining brightness data typed by the user in the brightness input box; adjusting the target brightness of the display device according to the typed brightness data; and continuing to execute the step of determining the target relative position between the light-transmitting area of ​​the multi-layer shading plate and the corresponding light-impermeable area according to the adjusted target brightness.

[0071] It can be understood that the brightness input request can be initiated by the user through the terminal. When the brightness input request is received, it indicates that the user intends to enter the brightness data that he or she approves, that is, the brightness data typed in the displayed brightness input box. In order to effectively improve the user experience, the target brightness of the display device will be adjusted according to the typed brightness data, and then the step of adjusting the brightness of the display device will be continued. For example, it is determined that the target brightness of the display device is 80%, and the typed brightness data is 85%. At this time, the target brightness of the display device is adjusted to 85%.

[0072] This embodiment determines the target brightness of the display device according to the current ambient brightness when the current ambient brightness is greater than a preset brightness threshold; determines the target relative position between the light-transmitting area of ​​the multi-layer shading plate and the corresponding light-impermeable area according to the target brightness; and adjusts the brightness of the display device according to the target relative position through the target traction device of the shading plate. In the above manner, when it is determined that the current ambient brightness is greater than the preset brightness threshold, it indicates that the brightness needs to be adjusted. At this time, the target relative position between the light-transmitting area of ​​the multi-layer shading plate and the corresponding light-impermeable area is determined, and then the brightness of the display device is adjusted by adjusting the relative position between the light-transmitting area of ​​the multi-layer shading plate and the corresponding light-impermeable area through the target traction device of the shading plate, so that the brightness of the entire display device can be adjusted in a single adjustment manner, thereby effectively improving the efficiency of adjusting the brightness.

[0073] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 , step S20, including steps S201 to S203:

[0074] Step S201, determining the light brightness of a plurality of light sources disposed inside a display device.

[0075] It should be noted that a plurality of light sources are arranged inside the display device, and the light luminance of each light source is different, so the light luminance of each light source needs to be determined separately.

[0076] Further, step S201 includes: obtaining luminous information of a light source arranged inside the display device; obtaining light source information of multiple light sources, and an angle between a detection direction and a normal line of the light source; and determining the luminous brightness of the multiple light sources based on the luminous information, the light source information and the angle.

[0077] It should be understood that the luminous information may be the luminous intensity, and the light source information may be the light source area. After determining the angle between the detection direction and the light source normal, the luminous brightness of each light source is calculated in combination with the luminous information, specifically:

[0078]

[0079] Among them, L represents the luminous brightness of the light source, I represents the luminous information, A represents the light source information, and θ represents the angle between the detection direction and the normal of the light source.

[0080] Step S202, based on a transmittance algorithm, calculating the transmittance of the light panel according to the luminous brightness and the target brightness.

[0081] It can be understood that the transmittance algorithm refers to the algorithm used to calculate the transmittance of the shading plate. After obtaining the luminous brightness, the transmittance of the light plate is calculated in combination with the target brightness, specifically:

[0082]

[0083] Where T represents the light transmittance of the light panel, I0 represents the target brightness, and I t Indicates the luminous brightness.

[0084] Step S203 , determining a target relative position between a light-transmitting area and a corresponding light-impermeable area of ​​the multi-layer shading plate according to the light transmittance of the light plate.

[0085] It should be understood that the target relative position refers to the relative position between the light-transmitting area and the corresponding light-impermeable area of ​​the multi-layer shading plate. The relative positions between the light-transmitting area and the corresponding light-impermeable area of ​​the multi-layer shading plate are different, and the blocking areas between the light-transmitting area and the corresponding light-impermeable area are also different, which makes the light transmittance of the light panel different.

[0086] Further, step S203 includes: calculating a target blocking area between a light-transmitting area and a corresponding light-impermeable area of ​​a multi-layer light-shielding plate according to the light transmittance of the light panel; obtaining a current blocking area and a current relative position between the light-transmitting area and the corresponding light-impermeable area of ​​the multi-layer light-shielding plate; calculating a blocking area ratio according to the target blocking area and the current blocking area; and determining a target relative position between a light-transmitting area and a corresponding light-impermeable area of ​​the multi-layer light-shielding plate according to the blocking area ratio and the current relative position.

[0087] It can be understood that the target blocking area refers to the blocking area between the light-transmitting area and the corresponding light-impermeable area when the light transmittance between the multi-layer shading plates is the light transmittance of the light plate, and the blocking area ratio refers to the ratio of the current blocking area between the light-transmitting area and the corresponding light-impermeable area of ​​the multi-layer shading plate to the target blocking area. After calculating the blocking area ratio, the target relative position is determined in combination with the current relative position between the light-transmitting area and the corresponding light-impermeable area of ​​the multi-layer shading plate. In addition, for the blocking area between the light-transmitting area and the corresponding light-impermeable area of ​​the multi-layer shading plate, reducing the blocking area will increase the brightness of the display device, and increasing the blocking area will reduce the brightness of the display device.

[0088] This embodiment determines the luminous brightness of multiple light sources disposed inside the display device; based on the transmittance algorithm, calculates the light plate transmittance according to the luminous brightness and the target brightness; and determines the target relative position between the light-transmitting area of ​​the multi-layer shading plate and the corresponding light-impermeable area according to the light plate transmittance. In the above manner, after obtaining the luminous brightness of each light source disposed inside the display device, the light plate transmittance of the shading plate is calculated using the transmittance algorithm, and at this time, the target relative position between the light-transmitting area of ​​the multi-layer shading plate and the corresponding light-impermeable area is determined in combination with the shading area ratio, thereby effectively improving the accuracy of determining the target relative position.

[0089] This application also provides a brightness adjustment device, please refer to Figure 4 , the brightness adjustment device comprises:

[0092] The adjustment module 30 is used to adjust the brightness of the display device according to the relative position of the target through the target pulling device of the shading plate.

[0093] This embodiment determines the target brightness of the display device according to the current ambient brightness when the current ambient brightness is greater than a preset brightness threshold; determines the target relative position between the light-transmitting area of ​​the multi-layer shading plate and the corresponding light-impermeable area according to the target brightness; and adjusts the brightness of the display device according to the target relative position through the target traction device of the shading plate. In the above manner, when it is determined that the current ambient brightness is greater than the preset brightness threshold, it indicates that the brightness needs to be adjusted. At this time, the target relative position between the light-transmitting area of ​​the multi-layer shading plate and the corresponding light-impermeable area is determined, and then the brightness of the display device is adjusted by adjusting the relative position between the light-transmitting area of ​​the multi-layer shading plate and the corresponding light-impermeable area through the target traction device of the shading plate, so that the brightness of the entire display device can be adjusted in a single adjustment manner, thereby effectively improving the efficiency of adjusting the brightness.
