However, in actual display panels, in order to facilitate the layout and wiring of the light control chip and the light control area circuit, the light control address and the corresponding backlight area are usually not arranged in order, which causes confusion.

[0003] Furthermore, the correspondence between backlight areas and light control addresses differs across different display panels, necessitating a re-correlation of the light control addresses and backlight areas. However, currently, this correspondence process is entirely manual, resulting in low efficiency and high labor costs.

[0035] A recovery control module, connected to the main control module, is used to control the first motor and the second motor to move the brightness sensor to the initial position when the brightness value collected by the brightness sensor is greater than a threshold.

[0036] In another aspect, this disclosure provides a method for corresponding a light control address and a backlight area. The method for corresponding a light control address and a backlight area utilizes the apparatus for corresponding a light control address and a backlight area described in any one of the preceding claims. The method for corresponding a light control address and a backlight area includes:

[0037] The display panel is divided into multiple backlight areas, and the multiple backlight areas are numbered.

[0040] In one exemplary embodiment of this disclosure, the control device includes: a processing module, a control module, a sensor acquisition module, and a region determination module. The step of sending a start scanning command to the control device, controlling the brightness sensor to move along different backlight regions to obtain the acquisition results of the brightness sensor and determine the illuminated backlight regions, and sending the number of the illuminated backlight region to the backlight processor includes:

[0041] The backlight processor sends the start scanning command to the processing module.

[0042] The processing module sends control commands to the control module.

[0043] The control module controls the brightness sensor to move according to the control command;

[0044] The sensor acquisition module acquires the brightness value collected by the brightness sensor, and when the brightness value of the brightness sensor is greater than the threshold, it determines that the backlight area collected by the brightness sensor is lit, and sends a region determination command to the region determination module.

[0045] When the area determination module receives the area determination instruction, it determines the number of the backlight area where the brightness sensor is located, and transmits the number to the processing module;

[0049] The overall control module controls the brightness sensor to move along different backlight areas;

[0050] When the brightness value collected by the brightness sensor is greater than the threshold, the overall control module controls the brightness sensor to move to the initial position.

[0051] The technical solution provided in this disclosure can achieve the following beneficial effects:

[0052] The device for corresponding light control addresses and backlight areas provided in this disclosure includes: a support frame, a brightness sensor, and a control device. The display panel can be mounted on the support frame. The brightness sensor can also be mounted on the support frame and can be located on the light-emitting side of the display panel to collect the emitted light brightness of different backlight areas. The control device can control the brightness sensor to move along different backlight areas, and is used to acquire the collection results of the brightness sensor, determine the illuminated backlight area, and send the number of the illuminated backlight area to the backlight processor.

[0053] Therefore, when the backlight processor sends a light control address to the display panel, it can control a backlight area to be illuminated. At this time, the control device can control the brightness sensor to move between different backlight areas, and the brightness sensor can automatically detect the brightness values ​​of different backlight areas along its movement path. The control device can thus obtain the data collected by the brightness sensor in real time and automatically determine the illuminated backlight area. After determining the illuminated backlight area, the control device can automatically identify the number of the backlight area based on the location of the brightness sensor and send this number to the backlight processor to complete the correspondence between the light control address and the backlight area.

[0054] Therefore, by setting up a brightness sensor and a control device, this disclosure can automatically and quickly detect the number of the illuminated backlight area. Thus, compared with the prior art, the device provided by this disclosure that corresponds the light control address and the backlight area can improve the correspondence efficiency of the light control address and the backlight area and save labor costs.

[0071] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0072] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0073] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0074] In the field of display technology, zoned dynamic backlight control is a common backlight control technology. For example... Figure 1 As shown, in the regional dynamic backlight control, the display panel 1 can be divided into N*M backlight areas 11, each with a backlight number NM. Here, N is the maximum number of horizontal partitions, and M is the maximum number of vertical partitions. The brightness of the backlight corresponding to each backlight area 11 can be independently controlled. Based on the grayscale information of the corresponding area of ​​the image, the brightness of each backlight area 11 can be determined. The backlight can be an LED, but is not limited to it.

[0075] like Figure 2 As shown, to achieve independent control of the brightness of the backlight in each area, a light control chip 02 can be used to independently control the brightness of the backlight in each backlight area 11. Generally, a microcontroller is used as the backlight processor 01 to send the brightness data of each backlight area 11 to the corresponding light control chip 02. In this disclosure, the microcontroller and the light control chip 02 can communicate via the SPI protocol, but are not limited to this. Other communication protocols can also be used between the microcontroller and the light control chip 02, which can be selected according to actual needs, and all of these are within the scope of protection of this disclosure.

[0076] The aforementioned light control chip 02 can control the brightness of multiple backlight areas 11. The backlight processor 01 can access the light control chip 02 sequentially according to the light control address 03. The backlight processor 01 can send a set of data containing the light control address 03 and the backlight brightness, which is passed downstream sequentially via an SPI daisy chain. When the address of the light control chip 02 is the same as the light control address 03 sent by the backlight processor 01, the light control chip 02 will load the backlight data into its internal storage to control the backlight brightness of that backlight area 11.

[0077] However, the inventors of this disclosure discovered that in order to accurately map the corresponding brightness data to the corresponding backlight area 11, it is necessary to map the backlight area 11 and the light control address 03 one-to-one. However, in current practice, the light control chip 02 is located on the light control circuit board. For the sake of convenient layout and wiring of the light control IC and the light control area circuit, the mapping cannot be performed in the most ideal way, resulting in a confusion between the light control address 03 and the backlight area 11. Therefore, without knowing the mapping relationship, it is impossible to accurately apply the backlight brightness to the corresponding backlight area 11. Thus, it is necessary to re-map the backlight area 11 and the light control address 03.

[0078] Furthermore, the inventors of this disclosure have discovered that the current process of corresponding light control address 03 and backlight area 11 is all done manually, which results in low efficiency and high labor costs.

[0079] To address the aforementioned technical problems discovered by the inventors of this disclosure, the inventors of this disclosure have invented a device corresponding to a light control address 03 and a backlight region 11. This device is used to correspond the light control address 03 issued by the backlight processor 01 to the backlight region 11 in the display panel 1. In this disclosure, the backlight processor 01 can be an MCU processor, but is not limited to this; other backlight processors 01 can be selected according to actual needs, all of which are within the protection scope of this disclosure. The aforementioned display panel 1 may include multiple backlight regions 11, and each backlight region 11 may have a corresponding number.

[0080] like Figure 3 and Figure 7 As shown, in one embodiment of this disclosure, the device corresponding to the light control address 03 and the backlight area 11 may include: a support frame 2, a brightness sensor 3, and a control device 4. This device can automatically correspond multiple backlight areas 11 of the display panel 1 to different light control addresses 03, thereby improving correspondence efficiency and saving labor costs.

[0081] In this embodiment, the support frame 2 can be located on the light-emitting side of the display panel 1, or the display panel 1 can be mounted on the support frame 2. When the support frame 2 is located on the light-emitting side of the display panel 1, the support frame 2 can expose the light-emitting area of ​​the display panel 1. At this time, the display panel 1 can be fixed to a wall or other mounting bracket.

[0082] The brightness sensor 3 can be mounted on the support frame 2 and can be located on the light-emitting side of the display panel 1 to collect the light emission brightness of different backlight areas 11.

[0083] In one embodiment of this disclosure, such as Figure 5 and Figure 6 As shown, the brightness sensor 3 may include a light-shielding part 31 and a sensing part 32. The light-shielding part 31 can be connected to the support frame 2, and the sensing part 32 can be located within the light-shielding part 31. By incorporating a light-shielding part 31 into the brightness sensor 3, this disclosure ensures that when the brightness sensor 3 is aligned with the display panel 1, only the light emitted from the display panel 1 can enter the light-shielding part 31 and be sensed by the sensing part 32. This reduces the probability of ambient light being sensed by the sensing part 32, thereby improving the accuracy of the brightness sensor 3.

[0084] In this embodiment, the light-shielding part 31 can be a hollow cylinder, the sensing part 32 can be located at the bottom of the hollow cylinder, and the top of the hollow cylinder can be aligned with the display panel 1. This disclosure does not limit the specific shape of the light-shielding part 31. For example, the light-shielding part 31 can also be a triangular prism, a quadrangular prism, etc., which can be selected according to actual needs, and all of these are within the protection scope of this disclosure.

[0085] The control device 4 can be connected to the brightness sensor 3 to control the brightness sensor 3 to move along different backlight areas 11. The control device 4 can also be used to acquire the acquisition results of the brightness sensor 3 and determine the backlight area 11 that is lit, and send the number of the backlight area 11 that is lit to the backlight processor 01.

[0086] Therefore, when the backlight processor 01 sends a light control address 03 to the display panel 1, it can control a backlight area 11 to be lit. At this time, the control device 4 can control the brightness sensor 3 to move in different backlight areas 11, and the brightness sensor 3 can automatically detect the brightness value of different backlight areas 11 along its moving path. In this way, the control device 4 can obtain the acquisition results of the brightness sensor 3 in real time and automatically determine the backlight area 11 that has been lit. After the control device 4 determines the backlight area 11 that has been lit, it can automatically identify the number of the backlight area 11 according to the location of the brightness sensor 3, and send the number to the backlight processor 01 to complete the purpose of matching the light control address 03 with the backlight area 11.

[0087] Therefore, by setting up a brightness sensor 3 and a control device 4, this disclosure can automatically and quickly detect the number of the illuminated backlight area 11. Thus, compared with the prior art, the device provided by this disclosure that corresponds to the light control address 03 and the backlight area 11 can improve the correspondence efficiency of the light control address 03 and the backlight area 11 and save labor costs.

[0088] like Figure 3 In one embodiment of this disclosure, the support frame 2 may include a first support rod 21, a second support rod 22, and a third support rod 23. The second support rod 22 may be disposed opposite to the first support rod 21, and the display panel 1 may be located between the first support rod 21 and the second support rod 22, so that the light-emitting area of ​​the display panel 1 is exposed through the first support rod 21 and the second support rod 22.

[0089] The aforementioned third support rod 23 can be connected to the first support rod 21 and the second support rod 22, and the third support rod 23 can be located on the light-emitting side of the display panel 1. The third support rod 23 can reciprocate along the first direction Y under the control of the control device 4. The brightness sensor 3 can be mounted on the third support rod 23, so that when the third support rod 23 reciprocates along the first direction Y, the brightness sensor 3 can also reciprocate along the first direction Y. In addition, the brightness sensor 3 can also reciprocate along the second direction X. Wherein, the first direction Y is the extension direction of the first support rod 21, and the second direction X can be the extension direction of the third support rod 23. Thus, by making the brightness sensor 3 move along the first direction Y and the second direction X, the brightness sensor 3 can reach the position corresponding to each backlight area 11, thereby detecting the brightness of all backlight areas 11.

[0090] In this disclosure, the edge of the display panel 1 can also extend along the first direction Y and the second direction X. Furthermore, each backlight area 11 can be a rectangle, thus the display panel 1 can be divided into multiple rows and columns of backlight areas 11. The control device 4 can control the brightness sensor 3 to first sequentially collect the brightness values ​​of each backlight area 11 in the first row along the second direction X, then move along the first direction Y to the second row, and then sequentially collect the brightness values ​​of each backlight area 11 in the second row along the second direction X, and so on.

[0091] However, it is not limited to this. The control device 4 can also control the brightness sensor 3 to first collect the brightness values ​​of each backlight area 11 in the first column along the first direction Y, then move to the second column along the second direction X, and then collect the brightness values ​​of each backlight area 11 in the second column along the first direction Y, and so on.

[0092] In one embodiment of this disclosure, the first support rod 21 and the second support rod 22 can extend vertically, that is, the first direction Y can be vertical. The third support rod 23 can extend horizontally, that is, the second direction X can be horizontal.

[0093] In one embodiment of this disclosure, when the support frame 2 is located on the light-emitting side of the display panel 1, such as Figure 4 As shown, the first support rod 21 may further include a first limiter 211 and a second limiter 212. The first limiter 211 can be installed on the side of the first support rod 21 near the display panel 1, and the first limiter 211 can extend away from the first support rod 21. By setting the first limiter 211, the distance between the display panel 1 and the first support rod 21 in a third direction can be limited, thereby limiting the distance between the brightness sensor 3 and the display panel 1 in a third direction. This third direction can be the direction in which the first support rod 21 points towards the display panel 1.

[0094] In this embodiment, in order to prevent the first limiter 211 from damaging the display panel 1, the side of the first limiter 211 near the display panel 1 can be made of a soft material, such as rubber or sponge. The material can be selected according to actual needs, and all of this is within the protection scope of this disclosure.

[0095] Furthermore, this disclosure does not limit the extension length of the first limiter 211 in the third direction, and it can be set according to actual needs, which is also within the protection scope of this disclosure.

[0096] The aforementioned second limiter 212 can be installed on the side of the first support rod 21 near the second support rod 22, and the second limiter 212 can contact one edge of the display panel 1. By setting the second limiter 212, the positions of the first support rod 21 and the edge of the display panel 1 can be limited, thereby positioning the display panel 1 between the first support rod 21 and the second support rod 22.

[0097] In one embodiment of this disclosure, the second support rod 22 may further include a third limiter and a fourth limiter. The third limiter may be installed on the side of the second support rod 22 near the display panel 1, and the third limiter may extend away from the second support rod 22. By providing the third limiter, the distance between the display panel 1 and the second support rod 22 in the third direction can be limited, thereby further limiting the distance between the brightness sensor 3 and the display panel 1 in the third direction.

[0098] In this embodiment, in order to prevent the third limiter from damaging the display panel 1, the side of the third limiter near the display panel 1 can also be made of a soft material, such as rubber or sponge, which can be selected according to actual needs, and all of this is within the protection scope of this disclosure.

[0099] Furthermore, this disclosure does not limit the extension length of the third limiter in the third direction, and it can be set according to actual needs, which is also within the protection scope of this disclosure.

[0100] The aforementioned fourth limiter can be installed on the side of the second support rod 22 near the first support rod 21, and the fourth limiter can contact the other edge of the display panel 1. By setting the fourth limiter, the positions of the second support rod 22 and the edge of the display panel 1 can be limited, thereby further positioning the display panel 1 between the first support rod 21 and the second support rod 22.

[0101] In one embodiment of this disclosure, such as Figure 3As shown, the support frame 2 may further include a first pulley 24, a second pulley 25, and a third pulley. The first pulley 24 can be mounted on the first support rod 21 and is capable of reciprocating along the first direction Y, and the third support rod 23 can be connected to the first pulley 24. The second pulley 25 can be mounted on the second support rod 22 and is capable of reciprocating along the first direction Y, and the third support rod 23 can also be connected to the second pulley 25. By configuring the first pulley 24 and the second pulley 25, this disclosure enables the third support rod 23 to move more smoothly and stably when reciprocating along the first direction Y.

[0102] The aforementioned third pulley can be mounted on the third support rod 23 and can reciprocate along the second direction X, and the brightness sensor 3 can be connected to the third pulley. Therefore, by providing the third pulley, this disclosure enables the brightness sensor 3 to move more smoothly and stably along the second direction X.

[0103] In one embodiment of this disclosure, a first pulley 24 may be mounted on a first support rod 21 and the first pulley 24 may slide along the side wall of the first support rod 21; a second pulley 25 may be mounted on a second support rod 22 and the second pulley 25 may slide along the side wall of the second support rod 22; a third pulley may be mounted on a third support rod 23 and the third pulley may slide along the side wall of the third support rod 23.

[0104] In another embodiment of this disclosure, the first support rod 21 may be provided with a first slide rail extending along a first direction Y, and a first pulley 24 may be located within the first slide rail and the first pulley 24 may move along the first slide rail. The second support rod 22 may be provided with a second slide rail extending along the first direction Y, and a second pulley 25 may be located within the second slide rail and the second pulley 25 may move along the second slide rail. The third support rod 23 may be provided with a third slide rail extending along a third direction, and a third pulley may be located within the third slide rail and the third pulley may move along the third slide rail.

[0105] In one embodiment of this disclosure, the device corresponding to the light control address 03 and the backlight area 11 may further include: a first motor 5 and a second motor 6. The first motor 5 may be mounted on the bottom of the first support rod 21 and connected to the third support rod 23 to drive the third support rod 23 to reciprocate along the first direction Y. The second motor 6 may be mounted on one end of the third support rod 23 and connected to the brightness sensor 3 to drive the brightness sensor 3 to reciprocate along the second direction X.

[0115] Furthermore, the distance between the first support rod 21 and the second support rod 22 can also be adjusted to allow the use of display panels 1 of different widths, thereby further enhancing the environmental adaptability of the device corresponding to the light control address 03 and the backlight area 11.

[0116] In one embodiment of this disclosure, such as Figure 7 As shown, the control device 4 may include: a processing module 41, a control module 42, a sensor acquisition module 43, and a region determination module 44. The processing module 41 is connected to the backlight processor 01 to receive instructions from the backlight processor 01 and send the number of the illuminated backlight region 11 to the backlight processor 01. The control module 42 is connected to the processing module 41 to control the movement of the brightness sensor 3 according to the instructions issued by the processing module 41. The sensor acquisition module 43 is connected to the brightness sensor 3 to acquire the brightness value acquired by the brightness sensor 3, and when the brightness value acquired by the brightness sensor 3 is greater than a threshold, it determines that the backlight region 11 is illuminated and sends a region determination instruction. The region determination module 44 is connected to the sensor acquisition module 43 to receive the region determination instruction, and upon receiving the region determination instruction, determines the number of the backlight region 11 located by the brightness sensor 3 and transmits the number to the processing module 41.

[0117] In one embodiment of this disclosure, the control module 42 may include: a central control module 421, an initialization module 422, a scanning control module 423, and a recovery control module 424. The central control module 421 may be connected to the processing module 41 to receive control commands issued by the processing module 41. The initialization module 422 may be connected to the central control module 421 to control the first motor 5 and the second motor 6 to move the brightness sensor 3 to an initial position. The scanning control module 423 may be connected to the central control module 421 to control the first motor 5 and the second motor 6 to move the brightness sensor 3 along different backlight areas 11. The recovery control module 424 may be connected to the central control module 421 to control the first motor 5 and the second motor 6 to move the brightness sensor 3 to the initial position when the brightness value collected by the brightness sensor 3 is greater than a threshold.

[0118] In this embodiment, the initial position can be the center position of the backlight area 11 in the first row and first column among all backlight areas 11.

[0119] In one embodiment of this disclosure, the control module 42 may further include a first motor drive module 425 and a second motor drive module 426. The first motor drive module 425 can be connected to the initialization module 422, the scan control module 423, and the recovery control module 424 to receive instructions from these modules and drive the first motor 5 to operate. The second motor drive module 426 can be connected to the initialization module 422, the scan control module 423, and the recovery control module 424 to receive instructions from these modules and drive the second motor 6 to operate.

[0120] The control device 4 described above will be explained below with reference to specific embodiments.

[0121] First, such as Figure 8 As shown, the processing module 41 can receive an initialization command issued by the backlight processor 01. After receiving the initialization command, the processing module 41 can send an initialization control command to the main control module 421. The main control module 421 drives the initialization module 422 to work according to the initialization control command. At this time, the initialization module 422 controls the first motor drive module 425 and the second motor drive module 426 to work, so as to drive the first motor 5 and the second motor 6 to work, thereby causing the third support rod 23 to move along the first direction Y and the brightness sensor 3 to move along the second direction X, so that the brightness sensor 3 reaches the initial position.

[0122] In this embodiment, when the brightness sensor 3 is initially located at the upper left corner of the display panel 1, the third support rod 23 can be moved by half a first distance K along the first direction Y by the first motor 5, and the brightness sensor 3 can be moved by half a second distance W along the second direction X by the second motor 6. Here, the first distance K is the length of a backlight area 11 in the first direction Y, and the second distance W is the length of a backlight area 11 in the second direction X.

[0123] like Figure 9As shown, when the brightness sensor 3 reaches its initial position, the backlight processor 01 can send a light control address 03 and brightness data to illuminate the backlight area 11 corresponding to the light control address 03. At this time, the backlight processor 01 can send a start scanning command to the processing module 41. The processing module 41 can send control commands to the main control module 421, and the main control module 421 can drive the scanning control module 423 to work according to the control commands. The scanning control module 423 drives the first motor drive module 425 and the second motor drive module 426, so that the brightness sensor 3 can first sequentially collect the brightness values ​​of each backlight area 11 in the first row along the second direction X, then move along the first direction Y to the second row, and then sequentially collect the brightness values ​​of each backlight area 11 in the second row along the second direction X, and so on.

[0124] Alternatively, the scanning control module 423 can drive the first motor drive module 425 and the second motor drive module 426, so that the brightness sensor 3 first sequentially collects the brightness values ​​of each backlight area 11 in the first column along the first direction Y, then moves to the second column along the second direction X, and then sequentially collects the brightness values ​​of each backlight area 11 in the second column along the first direction Y, and so on.

[0125] In one embodiment of this disclosure, when the brightness sensor 3 moves along the second direction X, it can move by a second distance W each time, and when the brightness sensor 3 moves along the first direction Y, it can move by a first distance K each time, so that when the brightness sensor 3 reaches each backlight area 11, it is located at the center of the backlight area 11, thereby effectively increasing the accuracy of the brightness sensor 3.

[0126] In this embodiment, when the brightness sensor 3 reaches each backlight area 11, it can stay in that backlight area 11 for a period of time to further improve the accuracy of the brightness sensor 3's acquisition. This disclosure does not limit the dwell time of the brightness sensor 3; it can be selected and set according to the actual sensor type and acquisition requirements, all of which are within the protection scope of this disclosure.

[0127] When the brightness value acquired by the sensor acquisition module 43 from the brightness sensor 3 exceeds a threshold, it can be determined that the area is illuminated. The sensor acquisition module 43 then sends an area determination command to the area determination module 44. At this point, the brightness sensor 3 stops moving. Upon receiving the area determination command, the area determination module 44 determines the number of the illuminated backlight area 11 based on the displacement of the brightness sensor 3.

[0128] In this embodiment, the method for determining the number of the backlight area 11 can be as follows: for each movement along the first direction Y by a first distance K, the number corresponding to the first direction Y can be incremented by 1; for each movement along the second direction X by a second distance W, the number corresponding to the second direction X can be incremented by 1.

[0129] The area determination module 44 can transmit the label of the backlight area 11 to the main control module 421, which then transmits it to the processing module 41, and finally the processing module 41 transmits it to the backlight processor 01. The backlight processor 01 can then associate the label of the backlight area 11 with the light control address 03 it sends.

[0130] And, as Figure 10 As shown, when the brightness value collected by the brightness sensor 3 is greater than the threshold, the main control module 421 can drive the recovery control module 424 to move the brightness sensor 3 to the initial position, thus completing the correspondence between a light control address 03 and the backlight area 11.

[0131] In this disclosure, the above steps can be repeated continuously until all backlight areas 11 in the display panel 1 correspond to the light control address 03. Furthermore, it should be noted that after the first correspondence between the light control address 03 and the backlight area 11, the recovery control module 424 moves the brightness sensor 3 to its initial position, thus eliminating the need for the initialization module 422 to initialize the brightness sensor 3 in subsequent correspondence processes.

[0132] This disclosure also provides a method for corresponding the light control address 03 and the backlight region 11. This method for corresponding the light control address 03 and the backlight region 11 can be applied to the apparatus described above for corresponding the light control address 03 and the backlight region 11. This method for corresponding the light control address 03 and the backlight region 11 can improve the corresponding efficiency and save labor costs.

[0133] In one embodiment of this disclosure, such as Figure 11 As shown, the method corresponding to the light control address 03 and the backlight area 11 may include:

[0134] Step S10: Divide the display panel 1 into multiple backlight areas 11 and number the multiple backlight areas 11.

[0135] Step S20: Use the backlight processor 01 to send a light control address 03 and brightness data to the display panel 1 to light up the backlight area 11 corresponding to the light control address 03.

[0136] Step S30: Send a start scanning command to the control device 4 to control the brightness sensor 3 to move along different backlight areas 11, so as to obtain the acquisition results of the brightness sensor 3 and determine the backlight area 11 that is lit, and send the number of the backlight area 11 that is lit to the backlight processor 01.

[0137] The following is a detailed explanation of each of the above steps:

[0138] In step S10, the display panel 1 can be divided into N*M backlight areas 11, and each backlight area 11 can have a backlight number NM. Here, N can be the maximum number of partitions along the second direction X, and M can be the maximum number of partitions along the first direction Y.

[0139] In one embodiment of this disclosure, each backlight region 11 may be the same size, and each backlight region 11 extends the same length along the first direction Y, and the first backlight region 11 extends the same length along the second direction X.

[0140] In step S30, a start scanning command can be sent to the control device 4 to control the brightness sensor 3 to move along different backlight areas 11, so as to obtain the acquisition results of the brightness sensor 3 and determine the backlight area 11 that is lit, and send the number of the backlight area 11 that is lit to the backlight processor 01.

[0141] In one embodiment of this disclosure, the control device 4 may include: a processing module 41, a control module 42, a sensor acquisition module 43, and a region determination module 44. In step S30, the backlight processor 01 can send a start scanning command to the processing module 41. The processing module 41 can send a control command to the control module 42. The control module 42 can control the movement of the brightness sensor 3 according to the control command. The sensor acquisition module 43 can acquire the brightness value acquired by the brightness sensor 3, and when the brightness value acquired by the brightness sensor 3 is greater than a threshold, it determines that the backlight area 11 acquired by the current brightness sensor 3 is lit, and sends a region determination command to the region determination module 44. When the region determination module 44 receives the region determination command, it can determine the number of the backlight area 11 where the brightness sensor 3 is located and transmit the number to the processing module 41. Finally, the processing module 41 can send the number to the backlight processor 01.

[0142] In one embodiment of this disclosure, the control module 42 may include: a central control module 421, an initialization module 422, a scan control module 423, and a recovery control module 424. When the control module 42 controls the movement of the brightness sensor 3 according to control commands, the central control module 421 can control the initialization module 422 to move the brightness sensor 3 to its initial position. The central control module 421 can control the brightness sensor 3 to move along different backlight areas 11. When the brightness value collected by the brightness sensor 3 is greater than a threshold, the central control module 421 can control the brightness sensor 3 to move to its initial position.

[0143] In one embodiment of this disclosure, the control module 42 may further include a first motor drive module 425 and a second motor drive module 426. The first motor drive module 425 can receive instructions from the initialization module 422, the scan control module 423, and the recovery control module 424, and drive the first motor 5 to operate. The second motor drive module 426 can receive instructions from the initialization module 422, the scan control module 423, and the recovery control module 424, and drive the second motor 6 to operate.

[0144] The control device 4 described above will be explained below with reference to specific embodiments.

[0145] First, such as Figure 8 As shown, the processing module 41 can receive an initialization command issued by the backlight processor 01. After receiving the initialization command, the processing module 41 can send an initialization control command to the main control module 421. The main control module 421 drives the initialization module 422 to work according to the initialization control command. At this time, the initialization module 422 controls the first motor drive module 425 and the second motor drive module 426 to work, so as to drive the first motor 5 and the second motor 6 to work, thereby causing the third support rod 23 to move along the first direction Y and the brightness sensor 3 to move along the second direction X, so that the brightness sensor 3 reaches the initial position.

[0146] In this embodiment, when the brightness sensor 3 is initially located at the upper left corner of the display panel 1, the third support rod 23 can be moved by half a first distance K along the first direction Y by the first motor 5, and the brightness sensor 3 can be moved by half a second distance W along the second direction X by the second motor 6. Here, the first distance K is the length of a backlight area 11 in the first direction Y, and the second distance W is the length of a backlight area 11 in the second direction X.

[0147] like Figure 9As shown, when the brightness sensor 3 reaches its initial position, the backlight processor 01 can send a light control address 03 and brightness data to illuminate the backlight area 11 corresponding to the light control address 03. At this time, the backlight processor 01 can send a start scanning command to the processing module 41. The processing module 41 can send control commands to the main control module 421, and the main control module 421 can drive the scanning control module 423 to work according to the control commands. The scanning control module 423 drives the first motor drive module 425 and the second motor drive module 426, so that the brightness sensor 3 can first sequentially collect the brightness values ​​of each backlight area 11 in the first row along the second direction X, then move along the first direction Y to the second row, and then sequentially collect the brightness values ​​of each backlight area 11 in the second row along the second direction X, and so on.

[0148] Alternatively, the scanning control module 423 can drive the first motor drive module 425 and the second motor drive module 426, so that the brightness sensor 3 first sequentially collects the brightness values ​​of each backlight area 11 in the first column along the first direction Y, then moves to the second column along the second direction X, and then sequentially collects the brightness values ​​of each backlight area 11 in the second column along the first direction Y, and so on.

[0149] In one embodiment of this disclosure, when the brightness sensor 3 moves along the second direction X, it can move by a second distance W each time, and when the brightness sensor 3 moves along the first direction Y, it can move by a first distance K each time, so that when the brightness sensor 3 reaches each backlight area 11, it is located at the center of the backlight area 11, thereby effectively increasing the accuracy of the brightness sensor 3.

[0150] In this embodiment, when the brightness sensor 3 reaches each backlight area 11, it can stay in that backlight area 11 for a period of time to further improve the accuracy of the brightness sensor 3's acquisition. This disclosure does not limit the dwell time of the brightness sensor 3; it can be selected and set according to the actual sensor type and acquisition requirements, all of which are within the protection scope of this disclosure.

[0151] When the brightness value acquired by the sensor acquisition module 43 from the brightness sensor 3 exceeds a threshold, it can be determined that the area is illuminated. The sensor acquisition module 43 then sends an area determination command to the area determination module 44. At this point, the brightness sensor 3 stops moving. Upon receiving the area determination command, the area determination module 44 determines the number of the illuminated backlight area 11 based on the displacement of the brightness sensor 3.

[0152] In this embodiment, the method for determining the number of the backlight area 11 can be as follows: for each movement along the first direction Y by a first distance K, the number corresponding to the first direction Y can be incremented by 1; for each movement along the second direction X by a second distance W, the number corresponding to the second direction X can be incremented by 1.

[0153] The area determination module 44 can transmit the label of the backlight area 11 to the main control module 421, which then transmits it to the processing module 41, and finally the processing module 41 transmits it to the backlight processor 01. The backlight processor 01 can then associate the label of the backlight area 11 with the light control address 03 it sends.

[0154] And, as Figure 10 As shown, when the brightness value collected by the brightness sensor 3 is greater than the threshold, the main control module 421 can drive the recovery control module 424 to move the brightness sensor 3 to the initial position, thus completing the correspondence between a light control address 03 and the backlight area 11.

[0155] In this disclosure, the above steps can be repeated continuously until all backlight areas 11 in the display panel 1 correspond to the light control address 03. Furthermore, it should be noted that after the first correspondence between the light control address 03 and the backlight area 11, the recovery control module 424 moves the brightness sensor 3 to its initial position, thus eliminating the need for the initialization module 422 to initialize the brightness sensor 3 in subsequent correspondence processes.

[0156] It should be noted that the first aspect of this disclosure has already provided a detailed description and explanation of the structure, type, and connection method of each component and assembly in the device corresponding to the light control address 03 and the backlight area 11. Therefore, the method for the corresponding light control address 03 and the backlight area 11 in this aspect will not be described again in terms of the structure, type, and connection method of each component and assembly in the device corresponding to the light control address 03 and the backlight area 11. Please refer to the specific description in the first aspect, which is also within the protection scope of this disclosure.

[0157] In addition, it should be noted that any of the steps described above that are performed simultaneously or concurrently can be performed separately or in stages, and can be selected according to actual needs, all of which are within the scope of protection of this disclosure.
