[0046] Before introducing the technical solution of this application, let's go over the technical issues in related technologies in detail.

[0047] In related technologies, liquid crystal display devices often employ a display control motherboard that outputs a local illumination signal to the backlight driver unit to control the backlight panel to emit light in designated areas, i.e., controlling the illumination of specific backlight regions. For example, a mini backlight module. However, this approach results in a complex structure and high cost for the liquid crystal display device.

Figure 2 This is a schematic diagram of the structure of a backlight panel provided in one embodiment of this application.

[0049] This embodiment provides a liquid crystal display component 1, which includes a timing control module 10, a backlight module 11, and a processing module 12. The timing control module 10 is used to send a preset signal; wherein, the preset signal includes control coordinate information.

[0050] The processing module 12 is electrically connected to the timing control module 10 and the backlight driving unit 111. The processing module 12 is used to acquire information of a plurality of preset sub-pixels 1122. The information of the preset sub-pixels 1122 includes preset coordinate information and information of the corresponding light-emitting area 1121. The processing module 12 is also used to acquire the RGB value of the preset sub-pixels 1122 when the control coordinate information corresponds to the preset coordinate information, and to obtain the brightness value of the light-emitting area 1121 corresponding to the preset sub-pixels 1122 based on the RGB value. The backlight driving unit 111 is used to control the light-emitting area 1121 corresponding to the preset sub-pixels 1122 to emit light based on the brightness value.

[0051] Furthermore, the terms “including” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion.

[0052] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this application are used to distinguish different objects, rather than to describe a specific order.

[0053] This embodiment provides a liquid crystal display assembly 1, which comprises a timing control module 10, a backlight module 11, and a processing module 12. The liquid crystal display assembly 1 is widely used in various electronic devices, such as mobile phones, computers, or televisions.

[0054] The liquid crystal display assembly 1 provided in this embodiment includes a timing control module 10, used to send preset signals. These preset signals are commonly used to control the liquid crystal module 13 of the liquid crystal display assembly 1 to adjust the brightness of the liquid crystal display assembly 1. The timing control module 10 can also be understood as a timing control chip TCON (Timer Control Register). The preset signals include Mini-LVDS (Mini-Low Voltage Differential Signaling) signals, STV (Start Vertical) signals, CPV (Clock Pulse Vertical) signals, etc. The timing control module 10 is used to receive LVDS image data input signals, which include RGB data signals, clock signals, and control signals. The timing control module 10 is also used to send LVDS signals to drive the liquid crystal module 13. In this embodiment, the preset signals include control coordinate information. Optionally, the control coordinate information refers to information controlling a specific gate; or, information controlling a specific row of sub-pixels 1122; or, information controlling a specific column of sub-pixels 1122.

[0055] The liquid crystal display assembly 1 provided in this embodiment further includes a backlight module 11, comprising a backlight driving unit 111 and a backlight panel 112. The backlight driving unit 111 drives the backlight panel 112 to emit light, and the backlight panel 112 emits light of a preset color and brightness. The backlight panel 112 has a plurality of light-emitting areas 1121 arranged in an array, and each light-emitting area 1121 includes at least one sub-pixel 1122. The sub-pixel 1122 can emit light of a preset color and brightness. For example, the sub-pixel 1122 can be an R chip, a G chip, or a B chip, etc. For example, the backlight panel 112 has a 24×24 light-emitting areas 1121 arranged in an array, that is, the plurality of light-emitting areas 1121 are composed of 24 rows and 24 columns, with 24 light-emitting areas 1121 in each row and 24 light-emitting areas 1121 in each column.

[0056] Optionally, each light-emitting area 1121 has a preset sub-pixel 1122, or in other words, one preset sub-pixel 1122 corresponds to one light-emitting area 1121. The information of the preset sub-pixel 1122 includes preset coordinate information and the information of the corresponding light-emitting area 1121. The preset coordinate information represents the position of the preset sub-pixel 1122 within the backlight panel 112, and the information of the corresponding light-emitting area 1121 represents which light-emitting area 1121 within the backlight panel 112 the preset sub-pixel 1122 is located in.

[0057] It should be noted that this application does not limit the number of light-emitting areas 1121 and preset sub-pixels 1122. The number of light-emitting areas 1121 and preset sub-pixels 1122 in this application specification is only for illustrative purposes. Users can set the number of light-emitting areas 1121 and preset sub-pixels 1122 according to the actual size of the liquid crystal display component 1.

[0058] The liquid crystal display assembly 1 provided in this embodiment also includes a processing module 12 for receiving, processing, and transmitting signals. Typically, the signals contain one or more pieces of information. For example, the processing module 12 can be an ASIC chip or an FPGA chip. The processing module 12 can acquire information about multiple different preset sub-pixels 1122 and can also acquire preset signals. The processing module 12 can also determine whether control coordinate information corresponds to preset coordinate information; for example, whether control coordinate values ​​correspond to preset coordinate values; or whether information controlling a specific gate is equal to preset gate information; or whether information controlling a specific row is equal to preset row information; or whether information controlling a specific column is equal to preset column information. The processing module 12 can also acquire the RGB values ​​of the preset sub-pixels 1122 and calculate the brightness value of the light-emitting area 1121 corresponding to the preset sub-pixels 1122 based on the RGB values. The processing module 12 can also send the brightness value to the backlight driving unit 111 so that the backlight module 11 can achieve zonal control of brightness.

[0059] Specifically, the processing module 12 of this embodiment can acquire information about a preset signal and a preset sub-pixel 1122, and when the control coordinate information of the preset signal corresponds to the preset coordinate information of the preset sub-pixel 1122, acquire the RGB value of the preset sub-pixel 1122; and obtain the brightness value of the light-emitting area 1121 corresponding to the preset sub-pixel 1122 according to the RGB value, thereby controlling the light-emitting area 1121 corresponding to the preset sub-pixel 1122 to emit light according to the brightness value, so as to realize the zone control of the backlight panel 112.

[0060] Therefore, the liquid crystal display component 1 provided in this embodiment can make the preset signal sent by the timing control module 10 correspond to the information of the preset sub-pixel 1122, so as to realize the partition control and brightness adjustment of the backlight panel 112 through the preset signal sent by the timing control module 10, thereby simplifying the structure of the liquid crystal display device, reducing the cost limitation of the display control motherboard, and thus reducing the cost of the liquid crystal display device.

[0061] In other words, this embodiment uses the TCON control signal to control the backlight module 11, thereby achieving backlight area control and brightness adjustment, reducing the cost limitations of the display control motherboard, enabling low-cost display solutions to achieve zoned backlight control, and bringing a better user experience.

[0062] Please refer to this as well. Figures 1-2 ,and Figure 3 . Figure 3 This is a schematic diagram of the structure of the processing module 12 provided in one embodiment of this application. In one embodiment, the preset signal includes a CPV signal, each preset coordinate information includes a preset row information and a preset column information, and the processing module 12 includes a detection unit 121, a calculation unit 122, and an acquisition unit 123.

[0063] The detection unit 121 is used to detect the CPV signal; the calculation unit 122 is used to calculate the frequency of the CPV signal and obtain the row information of the control coordinate information based on the frequency of the CPV signal; when the row information of the control coordinate information is equal to the preset row information, the acquisition unit 123 is used to acquire the RGB value of the sub-pixel 1122 including the preset row information; the acquisition unit 123 is also used to acquire the preset column information to obtain the RGB value of the sub-pixel 1122 including the preset row information and the preset column information; the calculation unit 122 is also used to calculate the brightness value of the light-emitting area 1121 corresponding to the preset sub-pixel 1122 based on the RGB value of the sub-pixel 1122 including the preset row information and the preset column information.

[0064] In this embodiment, the preset signal includes a CPV signal, which is a gate movement signal. The frequency of the CPV signal can also be understood as the information currently controlling a specific gate. For example, if the frequency of the CPV signal is five, in other words, the fifth row / column of the gate is currently being controlled. Therefore, the row information of the control coordinate information is obtained based on the available frequency of the CPV signal. For example, when the frequency of the CPV signal is five, the fifth row of the gate is controlled, so the row information of the control coordinate information is the fifth row. Furthermore, each preset coordinate information includes a preset row information and a preset column information; for example, one preset coordinate information includes the third row and the third column; another preset coordinate information includes the fourth row and the eighth column.

[0065] The processing module 12 provided in this embodiment includes a detection unit 121, a calculation unit 122, and an acquisition unit 123. The detection unit 121 can detect the CPV signal, and the calculation unit 122 can cooperate with the detection unit 121 to calculate the frequency of the CPV signal, thereby obtaining the row information of the control coordinate information. For example, when the frequency of the CPV signal is twelve, the row information of the control coordinate information is the twelfth row, that is, the twelfth row of the gate line is currently being controlled.

[0066] When the row information of the control coordinate information equals the preset row information, or in other words, when the frequency of the CPV signal equals the preset row information, the acquisition unit 123 can acquire the RGB values ​​of the sub-pixels 1122 including the preset row information. For example, if the preset row information is the twelfth row, when the row information of the control coordinate information is the twelfth row, the row information of the control coordinate information equals the preset row information, and at this time, multiple RGB values ​​of multiple sub-pixels 1122 on the twelfth row of the grid are acquired; or, in other words, multiple RGB values ​​of all sub-pixels 1122 in the twelfth row are acquired.

[0067] The acquisition unit 123 can also acquire preset column information to obtain the RGB values ​​of sub-pixels 1122 that include preset row information and preset column information. For example, when there is only one preset coordinate information, the preset coordinate information includes the twelfth row and the twelfth column, and its preset column information is the twelfth column. By acquiring the aforementioned preset row information, the acquisition unit 123 can acquire the RGB values ​​of the preset sub-pixels 1122 that include the twelfth row and the twelfth column. As another example, when there are multiple preset coordinate information, one preset coordinate information includes the twelfth row and the twelfth column; another preset coordinate information includes the twelfth row and the twenty-fourth column; and yet another preset coordinate information includes the twelfth row and the thirty-sixth column. Its preset column information is the twelfth column, the twenty-fourth column, and the thirty-sixth column. By acquiring the aforementioned preset row information, the acquisition unit 123 can acquire the RGB values ​​of three different preset sub-pixels 1122 that include the twelfth row and the twelfth column, the twelfth row and the twenty-fourth column, and the twelfth row and the thirty-sixth column.

[0068] The calculation unit 122 can also calculate the brightness value of the light-emitting area 1121 corresponding to the preset sub-pixel 1122 based on the RGB values ​​of the sub-pixel 1122, which includes preset row information and preset column information. For example, when there is only one preset coordinate information, the calculation unit 122 can calculate the brightness value of the light-emitting area 1121 where the preset sub-pixel 1122 in the twelfth row and twelfth column is located based on the RGB values ​​of the preset sub-pixel 1122 in the twelfth row and twelfth column. For example, when there are multiple preset coordinate information, the calculation unit 122 can calculate the brightness value of one light-emitting area 1121 containing the preset sub-pixels 1122 in the 12th row and 12th column based on the RGB values ​​of the preset sub-pixels 1122 in the 12th row and 12th column; the calculation unit 122 can also calculate the brightness value of another light-emitting area 1121 containing the preset sub-pixels 1122 in the 12th row and 24th column based on the RGB values ​​of the preset sub-pixels 1122 in the 12th row and 24th column; the calculation unit 122 can also calculate the brightness value of yet another light-emitting area 1121 containing the preset sub-pixels 1122 in the 12th row and 36th column based on the RGB values ​​of the preset sub-pixels 1122 in the 12th row and 36th column, thereby obtaining the brightness values ​​of three light-emitting areas 1121.

[0069] Therefore, the liquid crystal display component 1 provided in this embodiment can make the frequency of the CPV signal correspond to the preset row information, so as to realize the zone control and brightness adjustment of the backlight panel 112 through the CPV signal sent by the timing control module 10, thereby simplifying the structure of the liquid crystal display device, reducing the cost limitation of the display control motherboard, and thus reducing the cost of the liquid crystal display device.

[0070] Please refer to this as well. Figures 1-3 In one embodiment, the processing module 12 is used to acquire multiple preset coordinate information;

[0071] The acquisition unit 123 is used to acquire the RGB value of the sub-pixel 1122 including one preset row information, and to acquire the preset column information including multiple preset coordinate information, so as to acquire the RGB value of the sub-pixel 1122 including one preset row information and multiple preset coordinate information.

[0072] The acquisition unit 123 is further configured to acquire the RGB value of the sub-pixel 1122 including another preset row information, and acquire the preset column information of multiple preset coordinate information, so as to acquire the RGB value of the sub-pixel 1122 including another preset row information; wherein, the light-emitting area 1121 including one preset row information is arranged adjacent to the light-emitting area 1121 including another preset row information.

[0073] In this embodiment, there are multiple preset coordinate information. Each preset coordinate information includes one preset row information and one preset column information. In other words, the preset row information of two preset coordinate information is different; and / or, the preset column information of two preset coordinate information is different.

[0074] For example, one set of preset coordinate information includes the twelfth row and the twelfth column; another set of preset coordinate information includes the twelfth row and the twenty-fourth column; yet another set of preset coordinate information includes the twelfth row and the thirty-sixth column; one set of preset coordinate information includes the twenty-fourth row and the twelfth column; another set of preset coordinate information includes the twenty-fourth row and the twenty-fourth column; yet another set of preset coordinate information includes the twenty-fourth row and the thirty-sixth column.

[0075] First, the acquisition unit 123 can acquire the RGB values ​​of sub-pixels 1122 including a preset row information, and acquire preset column information including multiple preset coordinate information, so as to acquire the RGB values ​​of sub-pixels 1122 including a preset row information and multiple preset coordinate information. For example, if a preset row information is the twelfth row, the acquisition unit 123 first acquires multiple RGB values ​​of all sub-pixels 1122 in the twelfth row, and then acquires multiple preset column information, which are the twelfth column, the twenty-fourth column, and the thirty-sixth column, thereby acquiring the RGB values ​​of multiple preset sub-pixels 1122 located in the twelfth row.

[0076] Secondly, the acquisition unit 123 can also acquire the RGB values ​​of sub-pixels 1122 that include another preset row information, and acquire preset column information with multiple preset coordinate information, so as to acquire the RGB values ​​of sub-pixels 1122 with multiple preset coordinate information including another preset row information. For example, if the other preset row information is the 24th row, the acquisition unit 123 first acquires the multiple RGB values ​​of all sub-pixels 1122 in the 24th row, and then acquires multiple preset column information, which are the 12th column, the 24th column, and the 36th column, thereby acquiring the RGB values ​​of multiple preset sub-pixels 1122 located in the 24th row.

[0077] Furthermore, the light-emitting area 1121 including one preset row information is arranged adjacent to the light-emitting area 1121 including another preset row information, or in other words, the light-emitting area 1121 including one preset row information is arranged alternately with the light-emitting area 1121 including another preset row information. For example, the light-emitting areas 1121 corresponding to multiple preset sub-pixels 1122 located in the twelfth row are arranged adjacent to the light-emitting areas 1121 corresponding to multiple preset sub-pixels 1122 located in the twenty-fourth row.

[0078] Therefore, the liquid crystal display component 1 provided in this embodiment first obtains the RGB values ​​of all preset sub-pixels 1122 of one row of light-emitting area 1121, and then obtains the RGB values ​​of all preset sub-pixels 1122 of another row of light-emitting area 1121. This not only effectively reduces the workload of the processing module 12 in one working period and reduces the power consumption of the processing module 12, but also improves the accuracy of the zoning control and brightness adjustment of the backlight panel 112.

[0079] Please refer to this as well. Figures 1-3 In one embodiment, the processing module 12 is used to acquire multiple preset coordinate information;

[0080] The acquisition unit 123 is used to acquire the RGB values ​​of the sub-pixels 1122 including multiple preset row information, and acquire multiple preset column information to acquire the RGB values ​​of the sub-pixels 1122 of the preset coordinate information of each of the light-emitting areas 1121.

[0081] For example, one set of preset coordinate information includes the twelfth row and the twelfth column; another set of preset coordinate information includes the twelfth row and the twenty-fourth column; yet another set of preset coordinate information includes the twelfth row and the thirty-sixth column; one set of preset coordinate information includes the twenty-fourth row and the twelfth column; another set of preset coordinate information includes the twenty-fourth row and the twenty-fourth column; yet another set of preset coordinate information includes the twenty-fourth row and the thirty-sixth column.

[0082] The acquisition unit 123 can acquire the RGB values ​​of sub-pixels 1122 including multiple preset row information, and acquire multiple preset column information to acquire the RGB values ​​of sub-pixels 1122 with preset coordinate information of each light-emitting area 1121.

[0083] For example, the preset row information includes the twelfth row and the twenty-fourth row. The acquisition unit 123 acquires multiple RGB values ​​of all sub-pixels 1122 in the twelfth row and multiple RGB values ​​of all sub-pixels 1122 in the twenty-fourth row. Then, it acquires multiple preset column information, which are the twelfth column, the twenty-fourth column, and the thirty-sixth column. This allows it to acquire multiple preset sub-pixels 1122 in the twelfth row and multiple preset sub-pixels 1122 in the twenty-fourth row, thereby obtaining the RGB values ​​of the preset sub-pixels 1122 of each light-emitting area 1121.

[0084] Therefore, the liquid crystal display component 1 provided in this embodiment first obtains the RGB values ​​of all preset sub-pixels 1122 in all rows, and then obtains the RGB values ​​of all preset sub-pixels 1122 in corresponding preset columns. This can improve the working efficiency of the processing module 12 in obtaining brightness values, thereby improving the product performance of the liquid crystal display device.

[0085] Please refer to this as well. Figures 1-3 In one embodiment, each of the light-emitting areas 1121 is composed of an array of N rows and M columns, with each row including M sub-pixels 1122 and each column including N sub-pixels 1122, where N and M are both positive integers; wherein, in the preset coordinate information of the preset sub-pixels 1122, the preset row information is N / 2 and the preset column information is M / 2, where N / 2 and M / 2 are both positive integers.

[0086] In this embodiment, each light-emitting area 1121 is composed of an array of N rows and M columns, with each row including multiple sub-pixels 1122 and each column including multiple sub-pixels 1122. For example, each light-emitting area 1121 is composed of an array of twenty-four rows and twenty-four columns, with each row having twenty-four sub-pixels 1122 and each column having twenty-four sub-pixels 1122. Optionally, N equals M. Optionally, both N and M are even numbers.

[0087] In the preset coordinate information of preset sub-pixel 1122, the preset row information is N / 2 and the preset column information is M / 2, where N / 2 and M / 2 are both positive integers. For example, when M is 24 and N is 24, the preset row information is the twelfth row and the preset column information is the twelfth column in the preset coordinate information.

[0088] Optionally, when N is odd, the default row information is N / 2, which can directly discard the decimal part and round to the nearest integer; or it can be rounded according to the rounding rules. Optionally, when M is odd, the default row information is M / 2, which can directly discard the decimal part and round to the nearest integer; or it can be rounded according to the rounding rules.

[0089] Therefore, the preset coordinate information provided in this embodiment is the coordinate information of the sub-pixel 1122 located at the center position within the light-emitting area 1121. By setting the coordinate information of the sub-pixel 1122 located at the center position as the preset coordinate information, the RGB values ​​and brightness values ​​obtained subsequently correspond to the sub-pixel 1122 located at the center position. This can reduce the halo phenomenon of the light-emitting area 1121, reduce interference with the light of another light-emitting area 1121, and improve the accuracy of the zonal control and brightness adjustment of the backlight panel 112.

[0090] It should be noted that when unifying the preset coordinate information of each light-emitting area 1121 to the preset coordinate information of multiple light-emitting areas 1121 on a single backlight panel 112, the preset coordinate information of each light-emitting area 1121 needs to be transformed using the same coordinate system. For example, in the preset coordinate information of the first light-emitting area 1121, the preset row information is the twelfth row and the preset column information is the twelfth column. The second light-emitting area 1121 is arranged in the same row and adjacent to the first light-emitting area 1121, and in the preset coordinate information of the second light-emitting area 1121, the preset row information is the twelfth row and the preset column information is the twenty-fourth column. The third light-emitting area 1121 is arranged in the same column and adjacent to the first light-emitting area 1121, and in the preset coordinate information of the third light-emitting area 1121, the preset row information is the twenty-fourth row and the preset column information is the twelfth column.

[0091] Please refer to this as well. Figures 1-3 In one implementation, when N is odd, the sub-preset row information is (N-1) / 2 or (N+1) / 2, where (N-1) / 2 and (N+1) / 2 are both positive integers; and / or, when M is odd, the sub-preset column information is (M-1) / 2 or (M+1) / 2, where (M-1) / 2 and (M+1) / 2 are both positive integers;

[0092] The sub-preset row information and / or the sub-preset column information can form a first sub-preset coordinate information and a second sub-preset coordinate information; the plurality of light-emitting areas 1121 have a center point, and the first sub-preset coordinate information is closer to the center point than the second sub-preset coordinate information, so as to obtain the first sub-preset coordinate information as the preset coordinate information.

[0093] In this embodiment, multiple light-emitting areas 1121 have a center point, which refers to the point located at the center of all light-emitting areas 1121 of the backlight panel 112.

[0094] Optionally, the sub-preset coordinate information composed of sub-preset row information and sub-preset column information can be: row (N-1) / 2 and column (M-1) / 2, or row (N-1) / 2 and column (M+1) / 2, or row (N+1) / 2 and column (M-1) / 2, or row (N+1) / 2 and column (M+1) / 2, row N / 2 and column (M-1) / 2, or row N / 2 and column (M+1) / 2, or row (N+1) / 2 and column M / 2, or row (N+1) / 2 and column M / 2.

[0095] Therefore, by selecting the first sub-preset coordinate information closer to the center point as the preset coordinate information, this embodiment can make the preset sub-pixel 1122 close to the center of the backlight panel 112, or in other words, make the preset sub-pixel 1122 far away from the edge of the backlight panel 112. This makes the brightness of the backlight panel 112 present an overall effect of diffusion from the center point with good continuity, which can reduce the halo phenomenon of the backlight panel 112 and improve the accuracy of the zonal control and brightness adjustment of the backlight panel 112.

[0096] It should be noted that when unifying the preset coordinate information of each light-emitting area 1121 to the preset coordinate information of multiple light-emitting areas 1121 on a backlight panel 112, the preset coordinate information of each light-emitting area 1121 needs to be transformed using the same coordinate system.

[0097] Please refer to this as well. Figures 1-3 In one embodiment, each of the light-emitting areas 1121 is arranged in an array of N rows and M columns, with each row including M sub-pixels 1122 and each column including N sub-pixels 1122, where N and M are both positive integers; wherein, the preset coordinate information includes third sub-preset coordinate information, fourth sub-preset coordinate information, fifth sub-preset coordinate information, and sixth sub-preset coordinate information; the third sub-preset coordinate information includes first row information and first column information, the fourth sub-preset coordinate information includes first row information and Mth column information, the fifth sub-preset coordinate information includes Nth row information and first column information, and the sixth sub-preset coordinate information includes Nth row information and Mth column information;

[0098] The acquisition unit 123 is further configured to acquire the RGB values ​​of the third sub-preset coordinate information, the fourth sub-preset coordinate information, the fifth sub-preset coordinate information, and the sixth sub-preset coordinate information. The calculation unit 122 is further configured to calculate the average brightness value of the third sub-preset coordinate information, the fourth sub-preset coordinate information, the fifth sub-preset coordinate information, and the sixth sub-preset coordinate information, so as to obtain the average brightness value as the brightness value of the light-emitting area 1121.

[0099] In this embodiment, the third, fourth, fifth, and sixth sub-preset coordinate information are the coordinate information located at the corner of the light-emitting area 1121, respectively.

[0100] For example, when M is 24 and N is 24, the third sub-preset coordinate information includes the first row information and the first column information, the fourth sub-preset coordinate information includes the first row information and the twenty-fourth column information, the fifth sub-preset coordinate information includes the twenty-fourth row information and the first column information, and the sixth sub-preset coordinate information includes the twenty-fourth row information and the twenty-fourth column information.

[0101] The acquisition unit 123 can also acquire the RGB values ​​of the third, fourth, fifth, and sixth sub-preset coordinate information. For example, the acquisition unit 123 can acquire the RGB values ​​of the above four different sub-preset coordinate information.

[0102] The calculation unit 122 can also calculate the average brightness value of the third, fourth, fifth, and sixth sub-preset coordinate information to obtain the average brightness value of the light-emitting area 1121. For example, the calculation unit 122 calculates the average brightness value of the four different sub-preset coordinate information based on the RGB values ​​of the four different sub-preset coordinate information, and uses the average brightness value as the brightness value of the light-emitting area 1121.

[0103] Therefore, by taking the average brightness value corresponding to multiple sub-preset coordinate information located at the corner of the light-emitting area 1121 as the brightness value of the light-emitting area 1121, this embodiment can reduce the halo phenomenon of the light-emitting area 1121 and improve the accuracy of the zonal control and brightness adjustment of the backlight panel 112.

[0104] It should be noted that when unifying the preset coordinate information of each light-emitting area 1121 to the preset coordinate information of multiple light-emitting areas 1121 on a backlight panel 112, the preset coordinate information of each light-emitting area 1121 needs to be transformed using the same coordinate system.

[0105] Please refer to this as well. Figures 1-2 In one embodiment, the liquid crystal display component 1 satisfies at least one of the following conditions:

[0106] The preset signal also includes an STV signal. The detection unit 121 is used to detect the STV signal, and when the detection unit 121 detects the STV signal, the detection unit 121 is also used to detect the CPV signal.

[0107] The preset signal also includes a Mini-LVDS signal, and the acquisition unit 123 is further used to acquire the Mini-LVDS signal to obtain the RGB value of the sub-pixel 1122.

[0108] In this embodiment, the preset signal also includes an STV signal, which is the gate activation signal. The STV signal can also be understood as information to start controlling the gate. Therefore, when the detection unit 121 detects the STV signal, it means that the gate control has started, so it starts detecting the CPV signal and causes the calculation unit 122 to calculate the frequency of the CPV signal.

[0109] In this embodiment, the preset signal also includes a Mini-LVDS signal, which is a low-voltage differential signal transmission. This signal includes the RGB values ​​of multiple sub-pixels 1122, or in other words, it includes the RGB values ​​of the image corresponding to the multiple sub-pixels 1122. Therefore, the acquisition unit 123 can obtain the RGB values ​​of the multiple sub-pixels 1122 by acquiring the Mini-LVDS signal, providing a basis for subsequently acquiring the RGB values ​​of the preset sub-pixels 1122.

[0110] Please refer to this as well. Figures 1-2 In one embodiment, the processing module 12 is further configured to obtain a brightness model, wherein the brightness model is Y = a × R + b × B + c × G; where Y is the brightness value, R is the R value in RGB, G is the G value in RGB, B is the B value in RGB, a ranges from 0.101 to 0.161, b ranges from 0.101 to 0.161, and c ranges from 0.101 to 0.161.

[0111] The processing module 12 is used to calculate the brightness value of the light-emitting area 1121 corresponding to the preset sub-pixel 1122 based on the RGB value of the preset sub-pixel 1122 and the brightness acquisition model.

[0112] Optionally, the value range of a is 0.121-0.141, the value range of b is 0.121-0.141, and the value range of c is 0.121-0.141. Further optionally, the brightness model is Y = 0.131 × R + 0.131 × B + 0.131 × G.

[0113] In related technologies, the minimum intensity of each color is typically defined as 0, and the maximum as 255. In this embodiment, the constants a, b, and c are all taken as values ​​between 101 and 161, which are in the middle of the color intensity range, so that the brightness intensity converted from RGB values ​​achieves a soft light effect, which reduces the power consumption of the liquid crystal display device and improves the user experience.

[0114] Optionally, the brightness model is Y = (0.257 × R) + (0.504 × G) + (0.098 × B) + 16; where Y is the brightness value, R is the R value in the RGB values, G is the G value in the RGB values, and B is the B value in the RGB values. The brightness value of the light-emitting area 1121 corresponding to the preset sub-pixel 1122 is calculated based on the above brightness model and RGB values.

[0115] Optionally, the LCD timing control chip TCON outputs a mini-LVDS signal, STV, and CPV signals to the ASIC chip. After detecting a high level in the STV signal output, the ASIC chip begins high-level detection of the CPV signal. When the timer reaches a preset high level, it obtains the X-coordinate of the backlight area. Simultaneously, after the mini-LVDS signal enters the ASIC chip, it reads the RGB data value of the corresponding row based on the X-coordinate, calculates the Y-coordinate according to the read row data value, and obtains the corresponding RGB values ​​for the X and Y coordinates. Based on the obtained RGB values ​​and a brightness model, it calculates the brightness value for the corresponding X and Y coordinates. The calculated X-coordinate, Y-coordinate, and brightness value are then transmitted to the driver control chip via an SPI signal according to a pre-set protocol to achieve backlight zone control.

[0116] Specifically, taking a 1920x1080 resolution, 512-zone backlight control as an example, the 512 zones are adapted to a 1920x1080 display, allocated in 24 x 24 blocks, with 24 in the Y direction and 24 in the X direction. In other words, the backlight panel has 24 x 24 light-emitting zones 1121. Furthermore, each light-emitting zone 1121 is composed of a 24-row and 24-column array. Preset sub-pixels 1122 are the sub-pixels 1122 centered on each light-emitting zone 1121. For example, preset coordinate information includes the 12th row and 12th column, the 12th row and 24th column, the 12th row and 36th column, the 24th row and 12th column, the 24th row and 24th column, and so on, including the 24th row and 36th column.

[0117] First, the CPV signal output by the TCON chip is read and counted. When the twelfth high level is read, the RGB data value of the corresponding twelfth row is read and defined as the first value A in the Y coordinate. Similarly, the RGB value of the twelfth column is counted and converted into the first value B1 in the X coordinate according to the formula. Then, the RGB value of the twenty-fourth column is counted and converted into the second value B2 in the X coordinate according to the formula. Then, the RGB value of the thirty-sixth column is counted and converted into the third value B3 in the X coordinate according to the formula. And so on, taking the 24 data corresponding to row A. Then, the corresponding brightness value is calculated according to the brightness model. It should be noted that the coordinate conversion here is based on the formula for calculating the sub-pixel 1122 at the center position of each light-emitting area 1121.

[0118] Similarly, retrieve all the A1, A2-A24 data corresponding to the Y direction. Then, calculate the corresponding brightness value based on the brightness model.

[0119] Then, the brightness values ​​corresponding to the twenty-four sets of XY are packaged and sent to the backlight driver chip via the SPI protocol according to the defined protocol to achieve light control in the corresponding area.

In other words, the timing control module 10 in this embodiment can control both the backlight module 11 and the liquid crystal module 13, thereby simplifying the structure of the liquid crystal display device, reducing the cost constraints of the display control motherboard, and thus reducing the cost of the liquid crystal display device.
