[0031] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0032] Liquid crystal display screens are usually used alone. In order to meet the demand for large screens in current exhibition display, conference room, command center and other use scenarios, related technologies will form a large screen by mutually splicing liquid crystal display screens for display. However, it is found in actual application that after the liquid crystal display screens are mutually spliced to form a large screen, the brightness and chroma consistency of the whole screen is poor, and the display effect is difficult to meet the visual needs of users. When different liquid crystal display screens are simply stacked to form a spliced wall, due to the differences in source manufacturers, batches, display parameters, service life and the like of each independent liquid crystal display screen, the brightness and chroma display of each liquid crystal display screen is inconsistent, so that after the liquid crystal display screens are mutually spliced to form a large screen, the brightness and chroma consistency of the whole screen is poor, the color of the edge joint area of the glue frame is bright or dark, and the display effect of the whole screen is difficult to meet the visual needs of users.

[0033] In view of this, the present application proposes a liquid crystal correction method, which can realize large-screen display through multi-panel splicing and improve display effect through liquid crystal correction. The applicant has found that the display of a liquid crystal display screen mainly relies on a liquid crystal driving board to drive a liquid crystal display panel to display. Since different liquid crystal display screens have different display effects, i.e., different liquid crystal display panels have different display effects, the correction coefficient for liquid crystal correction needs to be used with the liquid crystal display panel. However, in the field of liquid crystal display, the technology of liquid crystal driving boards and liquid crystal display panels is relatively mature, and different manufacturers in the industry have relatively unified design standards for liquid crystal driving boards and liquid crystal display panels. Adding a liquid crystal correction design to the liquid crystal driving board and the liquid crystal display panel, the new liquid crystal driving board and the liquid crystal display panel may not be compatible with the old liquid crystal driving board and the liquid crystal display panel without adding the liquid crystal correction. Therefore, based on the research findings of the present application, a liquid crystal correction scheme is proposed, which is more compatible with the existing liquid crystal driving board and liquid crystal display panel, meeting the large-screen visual demand and the use compatibility demand in the field of liquid crystal display.

[0034] In order to illustrate the technical solutions of the present application, specific embodiments will be described below.

[0035] Figure 1 An implementation flowchart of a liquid crystal correction method provided by an embodiment of the present application is shown, which can be applied to a liquid crystal processor and can be applicable to a situation that needs to meet the large-screen visual demand.

[0036] Among them, the liquid crystal processor refers to a device with image processing capability, which can provide a display picture for a liquid crystal display screen, and can specifically refer to a video processing device, an image processing device, a liquid crystal processing device, a seamless switcher or a splicing processor, etc.

[0037] In the embodiments of the present application, the liquid crystal processor can be connected with at least two liquid crystal display units, so that the multiple liquid crystal display units display different parts of the same picture, or so that each liquid crystal display unit displays a corresponding picture in multiple pictures.

[0038] Specifically, "multiple liquid crystal display units display different parts of the same picture" means that a complete picture is cropped into multiple sub-pictures, each liquid crystal display unit displays a different sub-picture, and the sub-pictures displayed by multiple liquid crystal display units can form a complete picture. It should be noted that in this case, the sub-pictures displayed by each liquid crystal display unit are different parts of the same picture, but the picture content can be the same or different, for example, the picture is a solid color picture (such as a solid white picture), and the actual picture content displayed by different liquid crystal display units is a solid color pattern.

[0039] Of course, in the embodiments of the present application, all display units connected by the liquid crystal processor can splice to display one picture, or part of the display units connected by the liquid crystal processor can splice to display one picture, which is not limited by the present application.

[0040] "Each liquid crystal display unit displays a corresponding picture in multiple pictures respectively" means that there are multiple pictures, each picture is transmitted to a liquid crystal display unit for display, and different liquid crystal display units display the pictures they need to display. It should be noted that in this case, the picture displayed by each liquid crystal display unit belongs to different pictures, but the picture content can be the same or different, for example, multiple pictures are all solid color pictures (such as solid white pictures), and different liquid crystal display units display different pictures in multiple pictures, but the actual picture content is all solid color patterns.

[0041] Among them, the liquid crystal display unit refers to a device with liquid crystal display capability, for example, it can refer to a display unit obtained by packaging a liquid crystal driving board and a liquid crystal display panel. The liquid crystal driving board can be used to drive the lamp points on the liquid crystal display panel to display a specific color, thereby realizing picture display.

[0042] That is, on the basis of the liquid crystal display unit of the related art, the present application proposes a liquid crystal processor for simultaneously connecting and controlling multiple liquid crystal display units, so that multiple liquid crystal display units can display the same or different pictures with the help of the liquid crystal processor, and then splice to display a larger size picture.

[0043] Specifically, as shown in Figure 2 The liquid crystal processor can include a control module, a processing module, and an output module, and the processing module is connected with the control module and the output module respectively.

[0044] The control module can refer to an ARM (Advanced RISC Machines) processor, a microcontroller unit (MCU), or other functional modules with data acquisition and data analysis capabilities. The processing module can refer to a field programmable logic gate array (FPGA), a video processing IC (Integrated Circuit Chip), a multi-processor system on chip (MPSoC), or other functional modules with image processing capabilities. The output module can refer to a functional module capable of outputting an image screen to a liquid crystal display unit, and can specifically include a video output interface and an interface chip corresponding to the video output interface. The interface chip can control the output of the relevant data of the screen to the liquid crystal display unit through the video output interface. For example, the video output interface can be a network port, and the interface chip can be a network port control chip. For another example, the video output interface can be a high-definition multimedia interface (HDMI) interface or other video transmission interface, and the interface chip can be an interface chip corresponding to the HDMI interface. Of course, the video transmission interface can also be a digital video interface (DVI), a serial digital interface (SDI), a digital video interface (DisplayPort, DP), or other media interfaces, and the application is not limited thereto. The interface chip can correspond to an interface chip for controlling data output for each type of interface.

[0045] The working process of the control module, the processing module, and the output module will be described below. Figure 1 The above-mentioned control module, processing module, and output module will be described below.

[0046] In step S101, the control module acquires a correction coefficient package.

[0047] The correction coefficient package is a data package carrying correction coefficients, and can carry correction coefficients of each liquid crystal display unit. The correction coefficients can be used to correct the to-be-displayed screen of the corresponding liquid crystal display unit.

[0048] Specifically, in some embodiments, the control module can acquire the correction coefficient package generated by the terminal device, which can be the host computer or the liquid crystal processor installed with the correction software, that is, the control module can acquire the correction coefficient package generated inside the liquid crystal processor or the correction coefficient package generated and sent outside the liquid crystal processor. The terminal device can generate the corresponding correction coefficient based on the difference between the current display effect of the liquid crystal display unit and the ideal display effect, and package the correction coefficients of each liquid crystal display unit into a data package to obtain the correction coefficient package.

[0049] In step S102, the processing module acquires the to-be-displayed picture of each liquid crystal display unit and the correction coefficient of each liquid crystal display unit, and corrects the to-be-displayed picture of the corresponding liquid crystal display unit based on the correction coefficient of each liquid crystal display unit to obtain the corrected display picture.

[0050] The to-be-displayed picture refers to the picture to be displayed by the liquid crystal display unit, which can be represented as an image data inside the liquid crystal processor. The processing module can acquire the image data generated inside the liquid crystal processor or the image data provided externally to obtain the to-be-displayed picture of each liquid crystal display unit.

[0051] If the liquid crystal display unit directly displays the to-be-displayed picture, there can be a certain difference between the display effect and the ideal display effect. Therefore, the processing module can correct the to-be-displayed picture of the corresponding liquid crystal display unit based on the correction coefficient to reduce the above difference to a certain extent, so that the display effect of the liquid crystal display unit when displaying the corrected display picture approaches the ideal display effect.

[0052] In step S103, the output module sends the corrected display picture of each liquid crystal display unit to the corresponding liquid crystal display unit for display.

[0053] Specifically, the output module can package the corrected display picture of each liquid crystal display unit into a data package respectively, and send it to the corresponding liquid crystal display unit. After receiving the data package, the liquid crystal display unit can parse the data package to obtain the corrected display picture to be displayed by itself, and control each light point on the liquid crystal display panel to display the corresponding color rendering, thereby displaying the corrected display picture.

[0054] In the embodiments of the present application, the correction coefficient package of the at least two liquid crystal display units spliced with each other is acquired by the liquid crystal processor, and after the display picture is corrected, the respective liquid crystal display units are controlled to display the respective corrected display pictures, so that the multiple liquid crystal display units can display one picture by splicing, or the corresponding pictures in the multiple pictures are displayed respectively, the multi-panel splicing and liquid crystal correction in the field of liquid crystal display are realized, the large-screen display is realized by the multi-panel splicing, and the display effect is improved by the liquid crystal correction, and the large-screen visual demand in the field of liquid crystal display is met.

[0055] The working process of the liquid crystal processor is described below.

[0056] In some embodiments, the control module can acquire the correction coefficient package generated by the terminal device. The terminal device is an upper computer or a liquid crystal processor installed with correction software. The upper computer is a control device connected with the liquid crystal processing device, and can be a mobile device such as a mobile phone or a tablet computer, or can be a desktop computer or other type of device. The correction software can be used to generate the correction coefficient package. When the terminal device is the liquid crystal processor, the correction software can be integrated into the control module, that is, the control module can be embedded with a control system carrying the correction software, or in other words, the control module is embedded with an operating system, and the correction software is installed under the operating system.

[0057] Specifically, the control module can acquire the correction coefficient package obtained by the terminal device processing the imaging image.

[0058] The imaging image is an image obtained by the acquisition device acquiring each liquid crystal display unit respectively, or an image obtained by the acquisition device acquiring multiple liquid crystal display units simultaneously. That is, a single imaging image is the image of one or more liquid crystal display units.

[0059] In the embodiments of the present application, at least part of the imaging of the lamp spots of the liquid crystal display unit in the imaging image is in a conglutination state. By the term "the imaging of the lamp spots is in a conglutination state", it is meant that there is no obvious dark band (i.e. there is no region with almost 0 luminous flux) between adjacent lamp spots. From the perspective of human eyes, although the approximate positions of the lamp spots (or the centers of the lamp spots) can be identified from the imaging image, there is no obvious boundary between adjacent lamp spots, and the overall image appears to be relatively blurred. The imaging of the adjacent lamp spots can be in an abutment state and / or in an overlapping state. Specifically, the imaging of the adjacent lamp spots in a conglutination state can include the imaging of the adjacent lamp spots in an abutment state and / or in an overlapping state. If the imaging of the adjacent lamp spots is in an overlapping state, the degree of overlap of the imaging of the adjacent lamp spots in the imaging image can be determined based on one or more of the following factors: the correction accuracy of the LCD display screen, the correction efficiency of the LCD display screen, and the influence of the degree of overlap of the imaging of the lamp spots on the accuracy of the extracted correction information. As an example, the degree of overlap of the imaging of the adjacent lamp spots in the imaging image can be between 10% and 80%. For example, the degree of overlap of the imaging of the adjacent lamp spots in the imaging image can be between 10% and 50%, or between 20% and 30%.

[0060] Correspondingly, the terminal device can acquire the imaging image, and acquire target information according to the imaging image, so as to generate the correction coefficient package based on the target information.

[0061] The target information is information used for correcting the liquid crystal display unit, and more specifically, information used for correcting the target display region. The target display region is part of the display region or the entire display region after the splicing of the at least two liquid crystal display units in the spliced wall. The target information can specifically include one or more of the following information: luminous flux information, brightness information, and chrominance information. The luminous flux information can be used to represent the luminous flux per unit area in the target display region. The brightness information can be used to represent the brightness of the target display region. The chrominance information can be used to represent the hue and / or saturation of the color of the target display region.

[0062] The specific process of the terminal device generating the correction coefficient package is described below.

[0063] Firstly, the user can install the correction software on the terminal device, and connect the acquisition device to the terminal device. Correspondingly, the at least two liquid crystal display units can be spliced to form an LCD spliced wall, and the at least two liquid crystal display units can be connected to the liquid crystal processor.

[0064] Then, the terminal device can acquire the imaging image, and acquire target information according to the imaging image, so as to generate the correction coefficient package based on the target information.

[0065] Specifically, reference is made toFigure 3 At step S301, the lamp points of the target display area are controlled to be in the lighted state.

[0066] Specifically, the lamp points of the at least two liquid crystal display units can be controlled to be in the lighted state. The lamp points mentioned herein can be lamp points of certain colors, for example, can be one or a combination of red lamp points, blue lamp points, or green lamp points.

[0067] At step S302, the acquisition device parameters of the acquisition device are adjusted so that the imaging of at least part of the lamp points in the target display area is in the conglutination state.

[0068] The acquisition device parameters can include one or more of the following parameters: aperture, exposure time, focal length (zoom lens), microfocus, and the like of the acquisition device.

[0069] It should be understood that there can be multiple ways to adjust the imaging of the lamp points to the conglutination state. For example, the proportion of the lamp points in the imaging image can be adjusted, that is, the number of pixels corresponding to each lamp point is adjusted, and one or more of the clarity of the imaging of the acquisition device and the peak value of the lamp points can also be adjusted so that such indicators meet certain requirements. The above indicators can be set according to actual needs or experience, and the present application does not limit this.

[0070] It should be understood that the present application does not specifically limit the order of steps S301 and S302. Moreover, if the acquisition device parameters themselves meet the requirements, step S302 can also be omitted.

[0071] As a preferred embodiment, the acquisition device parameters corresponding to lamp points of different colors are different. Specifically, the exposure time is mainly different, for example, under the same gray scale, green is relatively bright, and blue is relatively dark, so the exposure time of the acquisition device corresponding to different colors is different.

[0072] At step S303, after the acquisition parameters are adjusted, the acquisition device is controlled to capture the target display area to obtain an imaging image.

[0073] In some embodiments, the imaging image can be an image (such as a pure color image) formed after the lamp points of certain or some colors are lighted.

[0074] After obtaining the imaging image, the target information can be obtained according to the imaging image.

[0075] The implementation manner of obtaining the target information can be various, and the obtaining manner of the target information is described in detail below in combination with embodiments.

[0076] Before acquiring the target information, it is generally necessary to first perform lamp point positioning, i.e., to determine the positions of the lamp points in the imaging image, or to determine the correspondence between the lamp points and the pixels in the imaging image. Then, based on the pixels corresponding to the lamp points, the optical information corresponding to each lamp point can be determined, and then the target information can be determined.

[0077] There can be various lamp point positioning methods.

[0078] In some embodiments, the pixels corresponding to each lamp point in the imaging image can be calculated based on an edge detection algorithm, and then the optical information corresponding to each lamp point can be acquired according to the pixels corresponding to each lamp point.

[0079] In other embodiments, the target information can also be acquired from the imaging image based on the arrangement information of the target display region.

[0080] The arrangement information of the target display region can be used to indicate the arrangement manner and / or arrangement position of the lamp points in the target display region. For example, the arrangement information of the target display region can indicate the number of rows / columns of the lamp points included in the target display region, thereby indicating the arrangement manner or arrangement position of the lamp points in the target display region. Since the target display region is known, the arrangement information of the target display region is actually a kind of prior information that can be known in advance.

[0081] Taking a rectangular region as an example, the arrangement information of the target display region can be the resolution information of the target display region. For example, assuming that the resolution of the target display region is 1920x1080, and the imaging image is an image formed after all the red lamp points in the target display region are lit, the resolution information of the target display region can be directly used as the arrangement information. The resolution information can indicate that there are 1920 rows of lamp points arranged in the row direction and 1080 columns of lamp points arranged in the column direction of the target display region. Since the lamp points are generally uniformly arranged, the arrangement information is equivalent to indicating the specific positions of the lamp points in the imaging image, and the positions of the lamp points can be determined through simple calculation. For example, the imaging image can be uniformly divided into 1920x1080 pixel regions according to the resolution, and then each pixel region can represent the position of a lamp point.

[0082] More specifically, please refer to Figure 4 In step S401, the correspondence between the lamp points in the target display region and the pixels in the imaging image is determined according to the arrangement information of the target display region.

[0083] For example, the arrangement information indicates that there are 2kxlk lamp points arranged in the target display region, and assuming that the imaging image includes 6kx3k pixels, then one lamp point in the target display region corresponds to 3x3 pixels in the corresponding position of the imaging image.

[0084] For example, the imaging image can be sampled according to the arrangement information of the target display region, so that the pixels in the sampled imaging image correspond to the lamp points in the target display region one by one. In this way, the optical information of each pixel in the sampled imaging image can be directly used as the optical information of the lamp point corresponding to the pixel in the target display region. As a specific example, the arrangement information indicates that the target display region contains 2k x 1k lamp points, and the imaging image contains 6k x 3k pixels. The imaging image can be first sampled so that the imaging image contains 2k x 1k pixels. After the sampling operation, one lamp point in the target display region corresponds to one pixel at the corresponding position in the imaging image, which can simplify the subsequent calculation of optical information / target information.

[0085] It should be understood that there can be various ways to sample the imaging image mentioned above. For example, the neighboring pixels of the center pixel in the imaging image can be sampled by mean value (e.g., mean value down-sampling), or the neighboring pixels of the center pixel can be directly discarded. As an example, the mean value down-sampling in the column direction can be first performed on each column of pixels in the imaging image, so that the number of pixels in each column is sampled to be the same as the resolution in the height direction of the target display region. Then, the mean value down-sampling in the row direction can be performed on each row of pixels in the imaging image, so that the imaging image with the same resolution as the target display region is obtained. As another example, the mean value down-sampling in the row direction can be first performed on each row of pixels in the imaging image, so that the number of pixels in each row is sampled to be the same as the resolution in the width direction of the target display region. Then, the mean value down-sampling in the column direction can be performed on each column of pixels in the imaging image, so that the imaging image with the same resolution as the target display region is obtained. As yet another example, the mean value down-sampling in the row and column directions can be performed on the imaging image at the same time, until the imaging image with the same resolution as the target display region is obtained.

[0086] In step S402, the optical information corresponding to the lamp points in the target display region is determined according to the correspondence between the lamp points in the target display region and the pixels in the imaging image.

[0087] For example, the brightness information of the pixel corresponding to a certain lamp point in the imaging image can be directly used as the brightness information corresponding to the lamp point. As another example, the chrominance information of the pixel corresponding to a certain lamp point in the imaging image can be directly used as the chrominance information corresponding to the lamp point. As yet another example, the luminous flux information of the pixel corresponding to a certain lamp point in the imaging image can be directly used as the luminous flux information corresponding to the lamp point.

[0088] In step S403, the target information is obtained according to the optical information corresponding to the lamp points in the target display region.

[0089] For example, the brightness information of the target display region at a certain gray level can be calculated based on the imaging image captured by the acquisition device, and then the correction information of the target display region is determined based on the calculated brightness information, and the correction information is taken as the target information. For another example, the brightness information of the target display region at a certain gray level can be calculated based on the imaging image captured by the camera, and then the brightness uniformity of the target display region is determined based on the calculated brightness information, and the information representing the brightness uniformity is taken as the target information.

[0090] It is considered that the imaging image captured by the acquisition device will produce a certain amount of deformation. Such deformation is also sometimes referred to as perspective distortion, or perspective deformation. If the target display region is large, the deformation of some regions in the target display region in the imaging image will also be large. If the target display region can be divided into a plurality of display sub-regions, and the position information of the plurality of display sub-regions in the imaging image can be accurately obtained, the optical information corresponding to the plurality of display sub-regions can be extracted in units of display sub-regions. Compared with the deformation amount corresponding to the whole target display region, the deformation amount corresponding to the display sub-region is relatively small, and extracting optical information based on the display sub-region can improve the accuracy of information extraction.

[0091] In order to extract optical information based on the display sub-region, the position information of each display sub-region in the imaging image needs to be obtained. Embodiments of the present application propose a display sub-region positioning method based on a calibration image (or positioning image), in order to quickly and accurately obtain the position information.

[0092] Specifically, the calibration image can be additionally captured by the acquisition device after the parameter adjustment of the acquisition device is completed. The calibration image can be used to divide the target display region into a plurality of display sub-regions (or said calibration image contains the position information of the plurality of display sub-regions). Since the imaging image and the calibration image are images captured under the same acquisition device parameters and of the same display region (i.e. the target display region), the deformation presented by the two images is the same. Therefore, based on the position information of the plurality of display sub-regions contained in the calibration image, the positions of the plurality of display sub-regions in the imaging image are positioned, and the positioning result is accurate.

[0093] The number of display sub-regions into which the target display region is divided by the calibration image and the size of each display sub-region can be set according to actual conditions. For example, the plurality of display sub-regions can be set according to the following principle: so that after the acquisition device captures the image in each display sub-region, the deformation amount corresponding to the display sub-region is within an acceptable range (or the deformation amount corresponding to each display sub-region is within a range that can be basically ignored).

[0094] As a preferred embodiment, since the calibration images are for positioning, but the positions of the light points of different colors are different, the calibration images corresponding to the light points of different colors can make the positioning more accurate. Therefore, in some embodiments, the aforementioned imaging images can include a first imaging image and a second imaging image. The first imaging image and the second imaging image correspond to the light points of different colors in the target display area. Accordingly, the calibration images can include a first calibration image corresponding to the first imaging image, and a second calibration image corresponding to the second imaging image. The first calibration image and the second calibration image are different. The difference between the first calibration image and the second calibration image can be embodied in one or more of the following: the colors of the patterns in the first calibration image and the second calibration image are different; the position information of the display sub-areas provided by the first calibration image and the second calibration image is slightly different (because the positions of the light points of different colors in the target display area are slightly different).

[0095] For example, the first imaging image can be a red imaging image, and the second imaging image can be a blue imaging image. The red imaging image is matched with a red calibration image, and the optical information of the red light points is obtained based on the red calibration image and the red imaging image. The blue imaging image is matched with a blue calibration image, and the optical information of the blue light points is obtained based on the blue calibration image and the blue imaging image. Similarly, if it is necessary to obtain the optical information of the light points of mixed colors displayed by the target display area, a mixed color calibration image can be matched.

[0096] It should be understood that the order in which the target display area displays the calibration images and the patterns for extracting the optical information is not limited in the present application.

[0097] In some embodiments, the calibration image can include a plurality of patterns corresponding to a plurality of display sub-areas in the target display area. The calibration image divides the target display area into a plurality of display sub-areas by displaying the plurality of display sub-areas of the target display area, so as to position the positions of the plurality of display sub-areas in the imaging image. The plurality of patterns corresponding to the plurality of display sub-areas in the calibration image can be light and dark patterns. The light and dark patterns are beneficial to accurately identifying the boundaries of the display sub-areas. Taking the resolution of the target display area as 1920*1080 as an example, the screen can be displayed according to a chessboard pattern. Taking the green imaging image obtained by displaying the green light points of the target display area point by point as an example, a green and black chessboard pattern can be obtained, and each chessboard in the chessboard pattern can include 64*60 pixels, for example.

[0098] In addition to the chessboard, the calibration image can be one or a combination of the following: crosshairs, Aruco code, special lines, light points, and a grid. The special lines can be several vertical lines, for example, three vertical lines displayed in the target display area, so that the display area of the display screen can be divided into four display sub-areas. The Aruco code is a binary code, which can be understood as a rectangular code composed of only two colors. The scatter points are patterns composed of multiple points.

[0099] Specifically, referring to Figure 5 In steps S501 and S502, the target display area is controlled to present a calibration pattern; and the acquisition device is controlled to capture the target display area to obtain a calibration image of the target display area. The calibration pattern is used to divide the target display area into multiple display sub-areas. The description of the parameter adjustment of the acquisition device can be referred to the step S302.

[0100] In step S503, target information is obtained according to the imaging image and the calibration image.

[0101] Specifically, the imaging image can be divided into multiple images corresponding to the multiple display sub-areas according to the calibration image. For example, the calibration image contains position information of the multiple display sub-areas, and the imaging image can be divided into multiple images based on the position information, so that each image represents a display sub-area. Then, the optical information (or light color information) corresponding to the multiple display sub-areas is determined according to the multiple images, respectively; and the target information is obtained according to the optical information corresponding to the multiple display sub-areas.

[0102] More specifically, based on the target information and the preset target optical information, a correction coefficient of each liquid crystal display unit can be generated to correct the error between the optical information corresponding to each display sub-area and the preset target optical information. The correction coefficients of each liquid crystal display unit can be combined to generate a correction coefficient package.

[0103] Considering that the resolution of the acquisition device can be less than the resolution of the entire display area after the liquid crystal display units are spliced (i.e., the total resolution of the spliced screen), the present application also provides a partition correction method.

[0104] Specifically, the entire display area after the liquid crystal display units are spliced can be divided into multiple target display areas, and each target display area is a partial display area after the liquid crystal display units are spliced. The complete display area after the liquid crystal display units are spliced can be obtained by splicing the target display areas.

[0105] The acquiring the imaging images can include: controlling the acquisition device to sequentially capture the plurality of display regions to obtain a plurality of imaging images. At this time, target information of the target display region can be acquired according to the plurality of imaging images, and the correction coefficient package can be generated based on the target information.

[0106] Specifically, in some embodiments, each imaging image can correspond to one display sub-region, that is, the image captured when a single display sub-region is lit is an imaging image. At this time, target information of the target display region corresponding to the imaging image can be acquired according to the plurality of imaging images, and the correction coefficient package can be generated according to the target information.

[0107] Wherein, after obtaining the target information of each target display region, the correction coefficient of the corresponding target display region can be determined according to the target information of each target display region, the correction coefficients of the target display regions are combined to obtain the correction coefficient package. The target information of each target display region can also be fused, for example, the target information of adjacent target display regions is fused, the correction coefficient of each target display region is determined based on the fused target information, and the correction coefficient package is combined. Of course, the correction coefficients of each target display region can also be fused after the correction coefficient of the corresponding target display region is determined according to the target information of each target display region, and the fused correction coefficients are combined to generate the correction coefficient package. The present application does not limit this.

[0108] For example, the entire display region of the liquid crystal display unit after splicing can be divided into four target display regions. By controlling the four target display regions to light up in turn and capturing them respectively, four imaging images can be obtained, each imaging image being an image when one of the target display regions is lit. Based on each imaging image, the target information of the corresponding target display region can be acquired, and then the correction coefficient of the target display region is obtained. The correction coefficients of the four target display regions are combined to obtain the correction coefficient package. In this way, the correction of the liquid crystal display screen with high resolution can be completed by the acquisition device with low resolution.

[0109] Wherein, the target information of the corresponding target display region can be acquired based on each imaging image, and the method of acquiring the target information can refer to the foregoing, which will not be repeated here.

[0110] Correspondingly, the control module of the liquid crystal processor can receive the correction coefficient package sent by the terminal device and analyze it.

[0111] In some embodiments, the correction coefficient package also carries positioning information of each liquid crystal display unit. The positioning information can be information obtained according to the connection relationship between each liquid crystal display unit and the output module, and the position of each liquid crystal display unit in the spliced screen, which is a screen obtained by splicing the liquid crystal display units.

[0112] Specifically, before the liquid crystal correction is performed, the liquid crystal display units are spliced to form a spliced screen, and then the liquid crystal display units in a specific connection relationship are controlled to display, so as to determine the positions of the liquid crystal display units in the specific connection relationship in the spliced screen. When the correction coefficient package is generated, the correction coefficient package can carry positioning information, which can be used to position each liquid crystal display unit to determine the correction coefficient used by the liquid crystal display unit in each connection relationship. Specifically, the positioning information can be the module identifier of the output module to which the liquid crystal display unit is connected (or specifically the interface representation of the output interface), the serial number of the liquid crystal display unit in the aforementioned spliced wall, the coordinates of the liquid crystal display unit in the aforementioned spliced wall, and the like, which are not limited by the present application.

[0113] After the control module receives the correction coefficient package sent by the terminal device, the correction data package can be parsed to obtain the correction coefficient and the positioning information, and the correction coefficient and the positioning information are sent to the control module for correction by the control module. Furthermore, the liquid crystal display unit in a specific connection relationship can use the correction coefficient required by itself in the correction coefficient package for correction.

[0114] In some embodiments, the liquid crystal processor described above can further include an input module connected to the processing module. The input module can obtain the to-be-displayed picture of each liquid crystal display unit and transmit it to the processing module.

[0115] Specifically, the input module can include a video input interface and an interface chip corresponding to the video input interface. The video input interface can be used to receive the to-be-displayed picture, and the interface chip corresponding to the video input interface can be used to decode and process the to-be-displayed picture.

[0116] Correspondingly, the processing module obtains the to-be-displayed picture of each liquid crystal display unit transmitted by the input module and the correction coefficient of each liquid crystal display unit transmitted by the control module. Then, based on the correction coefficient of each liquid crystal display unit, the to-be-displayed picture of the corresponding liquid crystal display unit is corrected to obtain the corrected display picture.

[0117] Specifically, the input module can be connected with the input source, and then the picture input by the input source is obtained. Since the liquid crystal processor can be configured with multiple input modules, the liquid crystal drive board can be connected with one or more input sources. When the liquid crystal drive board is connected with multiple input sources, the "to-be-displayed picture" can be all pictures input by the input sources connected by any one or more input modules, or part of the pictures input by the input sources connected by any one or more input modules. For example, after two liquid crystal display units are spliced, the liquid crystal processor can obtain pictures input by four input sources through four input modules, but can control the two liquid crystal display units to display pictures input by two input sources respectively, or can control the two liquid crystal display units to display different sub-pictures in a picture input by one input source. The present application does not limit this.

[0118] Specifically, the correction coefficient package can include multiple data packages obtained by dividing each correction coefficient by the terminal device in units of liquid crystal display units or the aforementioned display sub-regions. Each data package can carry positioning information of the corresponding liquid crystal display unit or the corresponding display sub-region. The processing module can parse the data package, determine, based on the positioning information, which to-be-displayed picture the correction coefficient in the data package should act on, and then perform correction processing on the corresponding to-be-displayed picture based on the correction coefficient to obtain a corrected display picture.

[0119] It can be understood that the packaging and parsing methods of the above data package can be selected according to actual conditions, for example, the packaging method of the data package and the corresponding parsing method can be selected according to the limitation of the maximum data amount of the data package, the limitation of the data length of the data package by the hardware, etc.

[0120] Correspondingly, the output module can send the corrected display picture of each liquid crystal display unit to the corresponding liquid crystal display unit for display.

[0121] In some embodiments of the present application, the number of processing modules is the same as the number of output modules, or the number of output modules is in a multiple relationship with the number of processing modules, for example, the number of output modules can be 2 times, 4 times, etc. of the number of processing modules.

[0122] Specifically, when the number of processing modules is the same as the number of output modules, one processing module and one output module can be arranged on the same board card, and each board card simultaneously performs the processing step of step S102 and the output step of step S103. When the number of output modules is N times (N is a positive integer greater than 1) of the number of processing modules, one processing module can be connected with N output modules, and then one processing module performs step S102, and then transmits the corrected display picture to N output modules respectively, and N output modules perform the output step respectively.

[0123] In some embodiments of the present application, the output modules connected with the liquid crystal display units can be in one-to-one correspondence with the liquid crystal display units. In other words, one output module can carry one liquid crystal display unit. It should be noted that the liquid crystal processor can include a plurality of output modules, and the output modules connected with the liquid crystal display units can be some or all of the output modules, which are not limited in the present application.

[0124] Similarly, the output module can include a video output interface and an interface chip corresponding to the video output interface. The interface chip corresponding to the video output interface can be used for encoding processing of the corrected display picture, and the video output interface can be used for transmitting the encoded display picture to the corresponding liquid crystal display unit.

[0125] In the embodiments of the present application, the liquid crystal display unit can include a liquid crystal drive board and a liquid crystal display panel. The liquid crystal drive board is connected with the liquid crystal display panel. The output module can send the corrected display picture of each liquid crystal display unit to the corresponding liquid crystal drive board, so that the liquid crystal drive board drives the connected liquid crystal display panel to display according to the corrected display picture. Thus, the process of liquid crystal display control is completed.

[0126] It should be noted that in the embodiments of the present application, the input module, the output module, the processing module and the control module can be respectively arranged on different board cards, or at least two of the input module, the output module, the processing module and the control module can be arranged on the same board card.

[0127] As an example, the output module, the processing module and the control module can be arranged on the same board card, and at this time the liquid crystal processor is a single machine type device. The corrected coefficient obtained by the control module can be stored in the external memory of the processing module.

[0128] As an example, the output module and the processing module can be arranged on the same board card (output sub-card), and the control module can be arranged on another board card, and at this time the liquid crystal processor is a plug-in type device. The corrected coefficient obtained by the control module can be stored in the external memory of the output sub-card. The processing module can read the corrected coefficient from the external memory in the output sub-card and cache it in the memory of the processing module, and after the correction processing, the corrected display picture is sent to the liquid crystal display unit for display through the output module on the output sub-card.

[0129] As another example, the output module, the processing module and the control module can be arranged on different boards respectively, and the liquid crystal processor is also a plug-in device. The control module can store the obtained correction coefficients into an external memory of the processing module. The processing module can read the correction coefficients from the external memory and cache them into an internal memory of the processing module, and send the corrected display picture to the liquid crystal display unit for display through the output module after correction processing.

[0130] Optionally, since the aforementioned correction coefficients can be down-sampled, the processing module can perform up-sampling based on the correction coefficients to restore the correction coefficients used by each lamp point. The up-sampling can be implemented based on an interpolation algorithm. After up-sampling, the processing module can directly use the up-sampled correction coefficients for image processing, without the need to store the up-sampled correction coefficients into the memory again.

[0131] Correspondingly, please refer to Figure 6 The embodiment of the present application provides a liquid crystal correction method, which can be applied to a liquid crystal display system. The liquid crystal display system can include a terminal device, a liquid crystal processor and a liquid crystal display unit. The liquid crystal processor and the at least two liquid crystal display units are connected, so that the plurality of liquid crystal display units display different parts of the same picture, or so that each liquid crystal display unit displays a corresponding picture in the plurality of pictures respectively.

[0132] In step S601, the terminal device acquires an imaging image, and obtains target information according to the imaging image, so as to generate a correction coefficient package based on the target information.

[0133] The imaging image is an image acquired by a collection device for each liquid crystal display unit respectively, or an image acquired by the collection device for the plurality of liquid crystal display units simultaneously, and at least part of the lamp points of the liquid crystal display unit in the imaging image are in a sticking state.

[0134] In step S602, the liquid crystal processor processes the correction coefficient package according to the liquid crystal correction method, so as to send the corrected display picture of each liquid crystal display unit to the corresponding liquid crystal display unit for display.

[0135] In some embodiments, the acquisition of the imaging image includes: controlling the lamp points in a target display area to be in a lighting state, wherein the target display area is a part of the display area or the whole display area after splicing of the liquid crystal display units; adjusting a collection device parameter of a collection device, so that the imaging of at least part of the lamp points in the target display area is in a sticking state; and after the collection parameter is adjusted, controlling the collection device to take a picture of the target display area to obtain the imaging image.

[0136] In some embodiments, the imaging image is an image obtained by the acquisition device simultaneously capturing a plurality of the liquid crystal display units; and the obtaining the target information according to the imaging image comprises: obtaining the target information from the imaging image according to the arrangement information of the target display region.

[0137] In some embodiments, after adjusting the acquisition device parameter of the acquisition device, the liquid crystal correction method further comprises: controlling the target display region to present a calibration pattern, the calibration pattern being used to divide the target display region into a plurality of display sub-regions; controlling the acquisition device to capture the target display region to obtain a calibration image of the target display region; and the obtaining the target information according to the imaging image comprises: obtaining the target information according to the imaging image and the calibration image.

[0138] It should be understood that the specific process of the terminal device performing step S601 can refer to the foregoing description of the terminal device. The "liquid crystal correction method" performed by the liquid crystal processor in step S602 can refer to the description of the liquid crystal correction method in the foregoing description. Therefore, the present application will not be described in detail herein. Figures 1 to 5

[0139] Correspondingly, as shown in Figure 7 , the present application provides a liquid crystal display system, which comprises a terminal device, a liquid crystal processor and a plurality of liquid crystal display units. The liquid crystal display system can comprise a terminal device, a liquid crystal processor and a plurality of liquid crystal display units. The liquid crystal processor is connected to the plurality of liquid crystal display units, so that the plurality of liquid crystal display units display different parts of the same picture, or so that each liquid crystal display unit displays a corresponding picture in a plurality of pictures, respectively.

[0140] The terminal device can be used to obtain an imaging image, and obtain target information according to the imaging image, so as to generate a correction coefficient package based on the target information.

[0141] The imaging image is an image obtained by the acquisition device capturing each liquid crystal display unit respectively, or an image obtained by the acquisition device simultaneously capturing a plurality of liquid crystal display units, and at least part of the light points of the liquid crystal display unit in the imaging image are in a conglutination state.

[0142] The liquid crystal processor can be used to process the correction coefficient package according to the liquid crystal correction method described in Figures 1 to 5 , so as to send the corrected display picture of each liquid crystal display unit to the corresponding liquid crystal display unit for display.

[0143] It can be understood that the above-mentioned at least two liquid crystal display units can also belong to a part of the liquid crystal display system. The specific structure and working process of the liquid crystal display system can refer to the description of the liquid crystal display system in the foregoing description. Therefore, the present application will not be described in detail herein. Figures 1 to 6 It can be understood that the above-mentioned at least two liquid crystal display units can also belong to a part of the liquid crystal display system. The specific structure and working process of the liquid crystal display system can refer to the description of the liquid crystal display system in the foregoing description. Therefore, the present application will not be described in detail herein.​

[0144] It should be emphasized that, compared with the related art liquid crystal display link, the liquid crystal display system of the present application adds a liquid crystal processor before the liquid crystal drive board, and the liquid crystal processor realizes the splicing display and correction of multiple liquid crystal display panels, without the need to reassemble and design the liquid crystal drive board and the liquid crystal display panel in the liquid crystal display unit, that is, the liquid crystal processor can be connected on the existing liquid crystal drive board and the existing liquid crystal display panel to realize liquid crystal correction and multi-panel splicing, thereby improving the adaptability in actual application scenarios.

[0145] In order to reduce the complexity of the liquid crystal display link, the present application further provides another implementation manner, in which the liquid crystal drive board realizes the related functions of the aforementioned liquid crystal processor.

[0146] Specifically, please refer to Figure 8 The embodiment of the present application provides a liquid crystal correction method, which can be applied to a liquid crystal drive board.

[0147] The liquid crystal drive board is connected with a liquid crystal display panel and a terminal device, respectively, the liquid crystal display panel and the liquid crystal display panel connected with at least one other liquid crystal drive board display different parts of the same picture, or the liquid crystal display panel and the liquid crystal display panel connected with at least one other liquid crystal drive board display corresponding pictures in multiple pictures, respectively.

[0148] Specifically, please refer to Figure 9 The liquid crystal drive board can include an input module, a processing module and a driving module, and the processing module is connected with the input module and the driving module, respectively.

[0149] The input module can be an ARM processor, an MCU, or other functional modules with data acquisition and data analysis capabilities. The processing module can be an FPGA, a video processing IC, or other functional modules with image processing capabilities. The driving module can be a functional module capable of outputting image pictures to the liquid crystal display panel and driving the liquid crystal display panel to display pictures.

[0150] The working process of the above-mentioned input module, processing module and driving module will be described below. Figure 8 The above-mentioned liquid crystal correction method can include the following steps S801 to S803.

[0151] In step S801, the input module acquires the correction coefficient corresponding to the liquid crystal drive board and the picture to be displayed corresponding to the liquid crystal drive board.

[0152] The correction coefficient can be used to correct the picture to be displayed.

[0153] Specifically, the input module can obtain the correction coefficient from the terminal device. It should be understood that the input module can obtain a correction coefficient package generated by the terminal device, and parse the correction coefficient corresponding to the liquid crystal drive board from the correction coefficient package (carrying a plurality of liquid crystal drive boards), or directly obtain the correction coefficient corresponding to the liquid crystal drive board sent by the terminal device.

[0154] The terminal device can be a host computer installed with correction software. The terminal device can generate the corresponding correction coefficient based on the difference between the current display effect of the liquid crystal display panel and the ideal display effect.

[0155] Of course, the specific process of generating the correction coefficient / correction coefficient package by the terminal device can refer to the description in the foregoing, and will not be described here.

[0156] The to-be-displayed picture refers to the picture that the liquid crystal display panel connected to the liquid crystal drive board needs to display, which can be represented as an image data inside the liquid crystal display panel. The input module can obtain the image data provided internally or externally, and then obtain the to-be-displayed picture of the liquid crystal display panel.

[0157] In step S802, the processing module corrects the to-be-displayed picture based on the correction coefficient to obtain a corrected display picture.

[0158] If the liquid crystal display panel directly displays the to-be-displayed picture, there can be a certain difference between the display effect and the ideal display effect. Therefore, the processing module can correct the to-be-displayed picture of the connected liquid crystal display panel based on the correction coefficient of the liquid crystal drive board itself, to reduce the above difference to a certain extent, so that the display effect of the liquid crystal display panel when displaying the corrected display picture tends to be close to the ideal display effect. At the same time, it can also make the display effect of the liquid crystal display panel more consistent when it is spliced and displayed with other liquid crystal display panels.

[0159] In step S803, the driving module drives the corrected display picture to the liquid crystal display panel for display.

[0160] Correspondingly, after receiving the corrected display picture output by the processing module, the driving module can drive the liquid crystal display panel to display the corrected display picture.

[0161] In the embodiments of the present application, the correction coefficient of the liquid crystal drive board is obtained, and the to-be-displayed picture is corrected to control the connected liquid crystal display panel to display the corrected display picture, so that a plurality of liquid crystal display panels can display one picture, or display corresponding pictures in a plurality of pictures, realizing multi-panel splicing and liquid crystal correction in the liquid crystal display field. While realizing large-screen display through multi-panel splicing, the display effect is improved through liquid crystal correction, meeting the large-screen visual demand in the liquid crystal display field.

[0162] In some embodiments, the input module can acquire the correction coefficient corresponding to the liquid crystal driving board sent by the first terminal device, and the to-be-displayed picture corresponding to the liquid crystal driving board sent by the second terminal device. The first terminal device and the second terminal device can be the same or different devices.

[0163] For example, the first terminal device can be a desktop computer installed with correction software, and the second terminal device can be a video player. The desktop computer can be used as a correction device of the liquid crystal display panel to generate the correction coefficient of the liquid crystal driving board and output the correction coefficient to the liquid crystal driving board, and the video player can be used as a video source to output the picture to be displayed by the liquid crystal display panel.

[0164] For another example, the first terminal device and the second terminal device can be the same mobile phone. In this case, the mobile phone can be used as a video source to output the picture to be displayed by the liquid crystal display panel, and can also be used as a correction device of the liquid crystal display panel to generate the correction coefficient of the liquid crystal driving board and output the correction coefficient to the liquid crystal driving board.

[0165] The correction coefficient acquired by the input module can be a correction coefficient obtained by processing the imaging image of at least two liquid crystal display panels collected by the terminal device. The imaging image can be an image collected by the terminal device from the liquid crystal display panel, or an image collected from the liquid crystal display panel and the liquid crystal display panel connected to the other liquid crystal driving board.

[0166] In the embodiments of the present application, at least part of the lamp points of the panel of the at least two liquid crystal display units in the imaging image are in a processing sticking state. The process of acquiring the imaging image by the terminal device and obtaining the correction coefficient based on the imaging image can refer to the description of the terminal device above, and will not be described herein.

[0167] It can be understood that the specific working process of the input module, the processing module and the driving module for implementing the liquid crystal correction and display can correspond to the control module, the processing module and the output module in the liquid crystal processor described above, and will not be described herein.

[0168] Similarly, the input module, the processing module and the driving module can be arranged on different boards, or at least two of the input module, the processing module and the driving module can be arranged on the same board. For example, the input module and the processing module can be integrated in the MPSoC.
