In the field of display technology, the regional dynamic backlight control is a general backlight control technology. As shown in fig. 1, in the split-area dynamic backlight control, the display panel 1 may be split into N × M backlight areas 11, and each backlight area 11 may have a backlight number N-M. Wherein, N is the maximum number of the horizontal partitions, and M is the maximum number of the vertical partitions. The brightness of the backlight corresponding to each backlight region 11 can be independently controlled, and the brightness of each backlight region 11 can be determined based on the gray scale information of the region corresponding to the image. The backlight may be an LED lamp, but is not limited thereto.

As shown in fig. 2, in order to realize independent control of the brightness of the backlight in each area, the brightness of the backlight in each backlight area 11 can be independently controlled using the light control chip 02. A single chip microcomputer or the like is generally used as the backlight processor 01, and the luminance data of each backlight area 11 is transmitted to the corresponding light control chip 02. In the present disclosure, the single chip and the light control chip 02 may communicate with each other through the SPI protocol, but is not limited thereto, and the single chip and the light control chip 02 may also communicate with each other through other communication protocols, which may be selected according to actual needs, and these are all within the protection scope of the present disclosure.

The one light-controlling chip 02 may control the brightness of the plurality of backlight areas 11, and the backlight processor 01 may sequentially access the light-controlling chip 02 according to the light-controlling address 03. The backlight processor 01 can send a group of data with the light control address 03 and the backlight brightness, and sequentially transmit the data to the downstream in a Serial Peripheral Interface (SPI) daisy-chain manner, and 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 loads the backlight data into the light control chip 02 to control the backlight brightness of the backlight area 11.

However, the inventors of the present disclosure have found that in order to accurately correspond corresponding luminance data to the corresponding backlight areas 11, it is necessary to correspond the backlight areas 11 to the light control addresses 03 one to one. However, in the actual situation at present, the light-controlling chip 02 is located on the light-controlling circuit board, so that the light-controlling IC and the light-controlling area circuit are convenient to lay out and route, and cannot be corresponded according to the optimal corresponding manner, which may cause the light-controlling address 03 and the backlight area 11 to be confused, so that the backlight brightness cannot be accurately applied to the corresponding backlight area 11 without knowing the corresponding relationship. Therefore, the backlight area 11 and the light control address 03 need to be newly associated.

Moreover, the inventor of the present disclosure finds that, at present, manual operations are performed in the process of corresponding to the light control address 03 and the backlight area 11, which causes the problems of low corresponding efficiency and high labor cost.

In order to solve the above technical problems found by the inventors of the present disclosure, the inventors of the present disclosure invented a device corresponding to the light control address 03 and the backlight area 11. The means for corresponding the light control address 03 and the backlight area 11 are used for corresponding the light control address 03 emitted by the backlight processor 01 and the backlight area 11 in the display panel 1. In the present disclosure, the backlight processor 01 may be an MCU processor, but is not limited thereto, and other backlight processors 01 may be selected according to actual needs, which is within the protection scope of the present disclosure. The display panel 1 may comprise a plurality of backlight areas 11, and each backlight area 11 may have a corresponding number.

As shown in fig. 3 and 7, in one embodiment of the present disclosure, the means for corresponding the light control address 03 and the backlight area 11 may include: support frame 2, luminance sensor 3 and controlling means 4. The device for corresponding light control addresses 03 and backlight areas 11 can automatically correspond a plurality of backlight areas 11 of the display panel 1 to different light control addresses 03, so that the corresponding efficiency can be improved and the labor cost can be saved.

In this embodiment, the supporting frame 2 may be located on the light emitting side of the display panel 1 or the display panel 1 can be mounted on the supporting 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 may be fixed on a wall or other mounting frame.

The brightness sensor 3 may be mounted on the supporting frame 2 and may be located on the light-emitting side of the display panel 1, so as to collect the light-emitting brightness of different backlight areas 11.

In one embodiment of the present disclosure, as shown in fig. 5 and 6, the luminance sensor 3 may include: a light shielding portion 31 and a sensor portion 32. The light shielding portion 31 may be connected to the support frame 2, and the sensing portion 32 may be located inside the light shielding portion 31. According to the light shield part 31 arranged in the brightness sensor 3, when the brightness sensor 3 is aligned with the display panel 1, only light emitted by the display panel 1 can enter the light shield part 31 and be sensed by the sensing part 32, so that the probability that external environment light is sensed by the sensing part 32 can be reduced, and the acquisition accuracy of the brightness sensor 3 is improved.

In this embodiment, the light shielding portion 31 may be a hollow cylinder, the sensing portion 32 may be located at the bottom of the hollow cylinder, and the top of the hollow cylinder may be aligned with the display panel 1. The present disclosure does not limit the specific shape of the light shielding portion 31, for example: the light shielding portion 31 may be a triangular prism, a quadrangular prism, or the like, and may be selected according to actual needs, which is within the protection scope of the present disclosure.

The control device 4 may be connected to the brightness sensor 3 for controlling the brightness sensor 3 to move along different backlight areas 11, and the control device 4 may be configured to obtain the collecting result of the brightness sensor 3 and determine the lit backlight area 11, and send the number of the lit backlight area 11 to the backlight processor 01.

It can be seen that 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 may control the luminance sensor 3 to move in the different backlight areas 11, and the luminance sensor 3 may automatically detect luminance values of the different backlight areas 11 along a path along which it moves. The control device 4 can thereby acquire the acquisition result of the brightness sensor 3 in real time and automatically judge the lighted backlight area 11. After the control device 4 determines the lighted backlight area 11, the serial number of the backlight area 11 can be automatically identified according to the position of the brightness sensor 3, and the serial number is sent to the backlight processor 01, so as to fulfill the purpose of corresponding the light control address 03 and the backlight area 11.

Therefore, the backlight area 11 serial number that this disclosure is lighted through setting up luminance sensor 3 and controlling means 4, can be automatic and quick detection, and then for prior art, the device that corresponds light control address 03 and backlight area 11 that this disclosure provided can improve light control address 03 and backlight area 11's corresponding efficiency and save the human cost.

As illustrated in fig. 3, in one embodiment of the present disclosure, the support stand 2 may include: a first support bar 21, a second support bar 22 and a third support bar 23. The second support bar 22 may be disposed opposite to the first support bar 21, and the display panel 1 may be located between the first support bar 21 and the second support bar 22 to expose the light emitting area of the display panel 1 through the first support bar 21 and the second support bar 22.

The third supporting bar 23 can be connected to the first supporting bar 21 and the second supporting bar 22, and the third supporting bar 23 can be located at the light emitting side of the display panel 1, and the third supporting bar 23 can reciprocate along the first direction Y under the control of the control device 4. The luminance sensor 3 may be mounted on the third support bar 23 such that when the third support bar 23 reciprocates in the first direction Y, the luminance sensor 3 may also reciprocate in the first direction Y. In addition, the luminance sensor 3 is also capable of reciprocating in the second direction X. The first direction Y may be an extending direction of the first supporting bar 21, and the second direction X may be an extending direction of the third supporting bar 23. Thus, the present disclosure enables the luminance sensor 3 to reach a position corresponding to each backlight area 11 by moving the luminance sensor 3 in the first direction Y and the second direction X, so that the luminance of all the backlight areas 11 can be detected.

In the present disclosure, the edge of the display panel 1 may also extend in the first direction Y and the second direction X. Also, each of the backlight regions 11 may have a rectangular shape, so that the display panel 1 may be divided into a plurality of rows and a plurality of columns of the backlight regions 11. The control device 4 may control the luminance sensor 3 to sequentially acquire the luminance values of the backlight areas 11 in the first row along the second direction X, then move to the second row along the first direction Y, and then sequentially acquire the luminance values of the backlight areas 11 in the second row along the second direction X, and so on.

But not limited to this, the control device 4 may also control the brightness sensor 3 to collect the brightness values of the backlight areas 11 in the first column sequentially along the first direction Y, then move to the second column along the second direction X, and then collect the brightness values of the backlight areas 11 in the second column sequentially along the first direction Y, and so on.

Wherein, the first stopper 211 may be installed at a side of the first support bar 21 close to the display panel 1, and the first stopper 211 may extend in a direction away from the first support bar 21. By providing the first stopper 211, the distance between the display panel 1 and the first support bar 21 in the third direction can be defined so as to define the distance between the luminance sensor 3 and the display panel 1 in the third direction. The third direction may be a direction in which the first support bar 21 points to the display panel 1.

In this embodiment, in order to prevent the first stopper 211 from damaging the display panel 1, a side of the first stopper 211 close to the display panel 1 may be made of a soft material, for example: rubber, sponge, etc., can be selected according to actual needs, and all fall within the scope of the present disclosure.

In an embodiment of the present disclosure, the control module 42 may further include: a first motor drive module 425 and a second motor drive module 426. The first motor driving module 425 may be connected to the initialization module 422, the scan control module 423, and the recovery control module 424, and configured to 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 driving module 426 may be connected to the initialization module 422, the scan control module 423, and the recovery control module 424, and configured to 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.

The control device 4 will be described below with reference to a specific example.

First, as shown in fig. 8, the processing module 41 may receive an initialization instruction issued by the backlight processor 01. After receiving the initialization command, the processing module 41 may send an initialization control command to the overall control module 421, and the overall control module 421 drives the initialization module 422 to work according to the initialization control command. The initialization module 422 controls the first motor driving module 425 and the second motor driving module 426 to operate to drive the first motor 5 and the second motor 6 to operate, respectively, so that the third supporting rod 23 moves along the first direction Y and the luminance sensor 3 moves along the second direction X, thereby enabling the luminance sensor 3 to reach the initial position.

In the present embodiment, when the brightness sensor 3 is initially at the upper left corner of the display panel 1, the third support bar 23 may be moved by the first motor 5 by half the first distance K in the first direction Y, and the brightness sensor 3 may be moved by the second motor 6 by half the second distance W in the second direction X. The first distance K is a length of one backlight region 11 in the first direction Y, and the second distance W is a length of one backlight region 11 in the second direction X.

As shown in fig. 9, after the luminance sensor 3 reaches the initial position, the backlight processor 01 may transmit a light control address 03 and luminance data, thereby lighting the backlight area 11 corresponding to the light control address 03. At this time, the backlight processor 01 may transmit an instruction to start scanning to the processing module 41. The processing module 41 may be used to send a control instruction to the general control module 421, the general control module 421 may drive the scanning control module 423 to work according to the control instruction, and the scanning control module 423 drives the first motor driving module 425 and the second motor driving module 426, so that the luminance sensor 3 may sequentially acquire luminance values of the backlight areas 11 in the first row along the second direction X, then move to the second row along the first direction Y, and then sequentially acquire luminance values of the backlight areas 11 in the second row along the second direction X, and so on.

Or the scan control module 423 may drive the first motor driving module 425 and the second motor driving module 426, so that the luminance sensor 3 sequentially collects luminance values of the backlight areas 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 luminance values of the backlight areas 11 in the second column along the first direction Y, and so on.

In an embodiment of the present disclosure, when the luminance sensor 3 moves along the second direction X, the luminance sensor 3 may move by one second distance W each time, and when the luminance sensor 3 moves along the first direction Y, the luminance sensor 3 may move by one first distance K each time, so that when the luminance sensor 3 reaches each backlight area 11, the luminance sensor is located at the center of the backlight area 11, thereby effectively increasing the accuracy of the acquisition of the luminance sensor 3.

In the present embodiment, when the luminance sensor 3 reaches each backlight area 11, the luminance sensor may stay in the backlight area 11 for a certain time to further improve the accuracy of the acquisition of the luminance sensor 3. The residence time of the brightness sensor 3 is not limited in the present disclosure, and can be selected and set according to the type of the actual sensor and the requirement of acquisition, which are all within the protection scope of the present disclosure.

When the brightness value acquired by the brightness sensor 3 acquired by the sensor acquisition module 43 is greater than the threshold value, it may be determined that the area is lit. The sensor acquisition module 43 may then send a zone determination instruction to the zone determination module 44. And, at this time, the luminance sensor 3 does not move any more. When the area determination module 44 receives the area determination instruction, the number of the lit backlight area 11 may be determined according to the displacement of the luminance sensor 3.

In this embodiment, the method for determining the number of the backlight area 11 may be: every time the first direction Y is moved by a first distance K, the number corresponding to the first direction Y may be increased by 1, and every time the second direction X is moved by a second distance W, the number corresponding to the second direction X may be increased by 1.

The area determination module 44 may transmit the label of the backlight area 11 to the general control module 421, and then the general control module 421 transmits the label to the processing module 41, and finally the processing module 41 transmits the label to the backlight processor 01. The backlight processor 01 can correspond the serial number of the backlight area 11 to the light control address 03 sent by the backlight area.

Moreover, as shown in fig. 10, when the brightness value collected by the brightness sensor 3 is greater than the threshold value, the total control module 421 may be used to drive the recovery control module 424 to move the brightness sensor 3 to the initial position, so as to complete the correspondence between the light control address 03 and the backlight area 11.

In the present disclosure, the above steps may be repeated until all of the backlight regions 11 in the display panel 1 correspond to the light control addresses 03. Moreover, it should be noted that, after the light control address 03 and the backlight area 11 are corresponded for the first time, the recovery control module 424 moves the luminance sensor 3 to the initial position, so that the luminance sensor 3 does not need to be initialized by the reuse initialization module 422 in the subsequent correspondence process.

Another aspect of the present disclosure provides a method of corresponding the light control address 03 and the backlight area 11. The method for corresponding to the light-controlling address 03 and the backlight area 11 can be applied to the above-mentioned device for corresponding to the light-controlling address 03 and the backlight area 11.

The above steps are explained in detail below:

in step S10, the display panel 1 may be divided into N × M backlight regions 11, and each backlight region 11 may have a backlight number N-M. Where N may be the maximum number of partitions in the second direction X, and M may be the maximum number of partitions in the first direction Y.

In step S30, a scanning start instruction may be sent to the control device 4, the luminance sensor 3 may be controlled to move along different backlight areas 11 to acquire the acquisition result of the luminance sensor 3 and determine the lit backlight area 11, and the number of the lit backlight area 11 may be sent to the backlight processor 01.

In one embodiment of the present disclosure, the control device 4 may include: a processing module 41, a control module 42, a sensor acquisition module 43, and an area determination module 44. In step S30, a start scan instruction may be sent to the processing module 41 by the backlight processor 01. The processing module 41 may be utilized to send control instructions to the control module 42. The control module 42 may control the movement of the luminance sensor 3 according to the control command. The sensor acquisition module 43 may be used 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 the threshold, determine that the backlight area 11 acquired by the current brightness sensor 3 is lit, and send an area determination instruction to the area determination module 44. When the area determination module 44 receives the area determination instruction, the number of the backlight area 11 where the luminance sensor 3 is located may be determined, and the number may be transmitted to the processing module 41. Finally, the number may be sent to the backlight processor 01 by the processing module 41.

In one embodiment of the present disclosure, the control module 42 may include: a general control module 421, an initialization module 422, a scan control module 423, and a recovery control module 424. In the control module 42 controlling the movement of the luminance sensor 3 according to the control instruction, the general control module 421 may be utilized to control the initialization module 422 to operate so as to move the luminance sensor 3 to the initial position. The overall control module 421 can be used to control the luminance sensor 3 to move along different backlight areas 11. When the brightness value collected by the brightness sensor 3 is greater than the threshold value, the total control module 421 is used to control the brightness sensor 3 to move to the initial position.

In one embodiment of the present disclosure, the control module 42 may further include: a first motor drive module 425 and a second motor drive module 426. The first motor driving module 425 may be configured to 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 driving module 426 may be configured to 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.

First, as shown in fig. 8, the processing module 41 may receive an initialization instruction issued by the backlight processor 01. After receiving the initialization instruction, the processing module 41 may send an initialization control instruction to the overall control module 421, and the overall control module 421 drives the initialization module 422 to operate according to the initialization control instruction. The initialization module 422 controls the first motor driving module 425 and the second motor driving module 426 to operate to drive the first motor 5 and the second motor 6 to operate, respectively, so that the third supporting rod 23 moves along the first direction Y and the luminance sensor 3 moves along the second direction X, thereby enabling the luminance sensor 3 to reach the initial position.

When the brightness value acquired by the brightness sensor 3 acquired by the sensor acquisition module 43 is greater than the threshold value, it may be determined that the area is lit. The sensor acquisition module 43 may then send a zone determination instruction to the zone determination module 44. And, at this time, the luminance sensor 3 is not moved any more. When the area determination module 44 receives the area determination instruction, the number of the lit backlight area 11 may be determined according to the displacement of the luminance sensor 3.

Moreover, as shown in fig. 10, when the brightness value collected by the brightness sensor 3 is greater than the threshold, the overall control module 421 may be used to drive the recovery control module 424, so as to move the brightness sensor 3 to the initial position, thereby completing the correspondence between the light-controlling address 03 and the backlight area 11.
