[0048] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0049] The following is combined with Figures 1-5 The present invention describes a liquid crystal display consistency correction method.

[0050] Figure 1 This is one of the flowcharts illustrating the liquid crystal display consistency correction method provided by the present invention, such as... Figure 1 As shown, the method includes:

[0051] Step 110: Receive the full-screen color image, full-screen plane correction data and full-screen depth correction data sent by the data processing terminal 202.

[0052] Optionally, Figure 2 This is one of the schematic diagrams of the architecture of the liquid crystal display consistency correction method provided by the present invention, such as... Figure 2 As shown, the aforementioned full-screen color image can be the RGB information of the entire LCD screen measured in real time by the measuring end 201 through contact with the LCD screen. The RGB information is based on the three primary colors R (Red), G (Green), and B (Blue), and is produced by superimposing them to different degrees to generate rich and wide colors. The RGB information can include the chromaticity information and brightness information of the entire LCD screen, that is, the consistency correction of color, chromaticity, and brightness is performed based on the RGB information.

[0053] Optionally, Figure 3 This is the second schematic diagram of the architecture of the LCD screen display consistency correction method provided by the present invention, as shown below. Figure 3 As shown, the measurement terminal 201 may include a circuit module 2011 and a motherboard CPU 2012. The circuit module 2011 has multiple sub-circuit modules 2011 arranged in a matrix. Each sub-circuit module 2011 is equipped with a sensor. The sensor senses the RGB information of the LCD screen in real time. The circuit module 2011 acquires the RGB information of the entire LCD screen at once, forms a full-screen color image, and uploads it to the data processing terminal 202 for subsequent correction.

[0054] It should be noted that, in order to avoid inconsistencies in measurement results caused by differences in measurement time, in this invention, the size of the circuit module 2011 is the same as the size of the LCD screen display area, so that the measurement end 201 can measure the RGB information of the entire LCD screen at once.

[0055] Optionally, the circuit module 2011 can be a tool, and after the circuit module 2011 is in contact with the display area of the liquid crystal screen, the RGB information of the full screen of the liquid crystal screen can be measured at one time, the measurement efficiency is greatly improved, the measurement time is reduced, and the consistency of the measurement result is ensured.

[0056] In addition, the information collected by the measurement end 201 also includes gray scale longitudinal data, that is, the gray scale longitudinal data from 0 to 255 is collected, each piece of data can form a color gray scale curve, and is uploaded to the data processing end 202 for subsequent correction.

[0057] Optionally, the sensor can be a color sensor, an RGB sensor, or a sensor used by a color temperature instrument probe, which can sense the RGB information of the full screen of the liquid crystal screen in real time and convert the RGB information into an electrical signal and upload the electrical signal to the data processing end 202.

[0058] Optionally, the full-screen color image, the full-screen plane correction data and the full-screen depth correction data are stored in the consistency correction end 203, and the consistency correction end 203 can be consistency corrected by using an FPGA (Field Programmable Gate Array).

[0059] Optionally, Figure 4 is the third schematic diagram of the architecture of the liquid crystal screen display consistency correction method provided by the application, as Figure 4 shown, the FPGA includes a main control and storage unit, a signal source decoding video stream unit, a plane data video stream generation unit, a data format conversion unit, an internal storage and lookup table (LUT) storage generation unit, a plane correction and video synthesis unit, and a depth correction and video synthesis unit, wherein the plane data video stream generation unit is connected with a plane data FLASH unit, the data format conversion unit is connected with a depth data FLASH unit, the signal source decoding video stream unit, the plane data video stream generation unit and the plane correction and video synthesis unit are all connected with the main control and storage unit, the plane data FLASH unit is connected with the plane data video stream generation unit, the depth data FLASH unit, the data format conversion unit, the internal storage and lookup table (LUT) storage generation unit and the depth correction and video synthesis unit are connected in sequence, the plane correction and video synthesis unit is connected with the depth correction and video synthesis unit, and in addition, the main control and storage unit is also connected with a double speed (DDR) storage unit. After the FPGA is consistency corrected, the liquid crystal screen is driven to display.

[0060] In step 120, based on the full-screen color image and the full-screen plane correction data, a full-screen color difference correction image is determined.

[0061] In order to carry out the plane correction, eliminate the color difference, the consistency correction end 203 carries out point-to-point image synthesis on the full-screen color image and the full-screen plane correction data, generates a full-screen color difference correction image, and realizes the real-time color difference correction of the liquid crystal screen point by point.

[0062] Optionally, the plane correction method comprises:

[0063] According to the image interpolation algorithm, the full-screen color image and the full-screen plane correction data are enlarged to the same scale;

[0064] According to the image synthesis algorithm, the full-screen color image and the full-screen plane correction data are point-to-point image synthesized to determine the full-screen color difference correction image.

[0065] In order to ensure the image uniformity, in the application, the image interpolation algorithm is used to enlarge the full-screen plane correction data, and the full-screen plane correction data is enlarged to the same scale as the full-screen color image, and then the point-to-point image synthesis is carried out through the image synthesis algorithm to realize the full-screen correction of the real-time color difference point by point, wherein the quality of the enlargement depends on the number of acquisitions and the size of the display area of the liquid crystal screen. In addition, the above-mentioned enlargement processing can support 4k resolution display, and can also support larger resolution display by expanding the FLASH unit storage space in the FPGA.

[0066] Optionally, the point-to-point image synthesis method comprises:

[0067] The full-screen color image and the full-screen plane correction data are subjected to color difference normalization processing, and the full-screen color image is subjected to color compensation;

[0068] The full-screen color image based on the color compensation and the full-screen plane correction data are subjected to data stream synthesis to determine the full-screen color difference correction image, and the full-screen color difference correction image is used to realize the correction of the real-time color difference point by point of the liquid crystal screen.

[0069] Specifically, since the correction image is different from the actual display data, it cannot be directly subjected to image Alpha synthesis, in the application, after the full-screen color image and the full-screen plane correction data are subjected to color difference normalization processing, the full-screen color image is compensated, and the data stream synthesis is carried out by converting into data stream to realize the correction of the real-time color difference point by point.

[0070] Step 130, the full-screen color difference correction image and the full-screen depth correction data are subjected to level correction to determine the full-screen consistency correction image, and are sent to the liquid crystal screen for display.

[0071] Specifically, since the human eye's perception of color and the physical light power of color are not proportional, that is, the RGB information perceived by the human eye and the physical light power belong to a nonlinear relationship, but a power function relationship, therefore, it is necessary to pass through the level correction to compensate for the color display difference existing in the liquid crystal screen. In addition, in the correction, the full-screen depth correction data is used as the correction standard data. Compared with the traditional single standard data, the full-screen depth correction data in the application is more average and optimized data measured by multiple sensors and processed, combined with plane correction, to complete the three-dimensional comprehensive correction of display plane and data depth.

[0072] Optionally, the level correction includes at least one of GAMMA correction and DICOM correction.

[0073] Optionally, as shown in FIG. 8, taking the FPGA as the consistency correction end 203 as an example, the consistency correction method includes: Figure 4

[0074] (1) The full-screen color image is decoded in the signal source decoding video stream unit and converted into main video stream data; the full-screen plane correction data is stored in the plane data FLASH unit and converted into plane video stream data by the plane data video stream generation unit; the full-screen depth correction data is stored in the depth data FLASH unit, converted in format by the data format conversion unit, and further stored in the internal cache and lookup table (LUT) storage generation unit;

[0075] (2) The main control and storage unit receives the main video stream data and the plane video stream data, and sends them to the plane correction and video synthesis unit. After the two data are enlarged to the same scale, point-to-point image synthesis is performed by the image synthesis algorithm to realize image plane correction and generate a full-screen color difference correction image, which is sent to the depth correction and video synthesis unit for subsequent correction;

[0076] (3) The depth correction and video synthesis unit receives the full-screen depth correction data sent by the internal cache and lookup table (LUT) storage generation unit, converts the full-screen depth correction data and the full-screen color difference correction image, and sends them to the liquid crystal screen after level correction for display, so that the liquid crystal screen corrected by the application is greatly reduced in screen difference and color unevenness, and can well eliminate the influence of medical or printed images on the liquid crystal screen, greatly ensuring the authenticity and consistency of the color.

[0077] ​The liquid crystal screen display consistency correction method provided by the application determines a full-screen color difference correction image by point-to-point image synthesis of a full-screen color image and full-screen plane correction data, realizes point-by-point correction of real-time color difference of the full-screen of the liquid crystal screen, and further realizes full-screen consistency correction of any non-uniform liquid crystal screen, improves the RGB color uniformity of the liquid crystal screen and the display effect.

[0078] The application further provides a liquid crystal screen display consistency correction method, Figure 5 FIG. 2 is a flowchart of the liquid crystal screen display consistency correction method provided by the application, and FIG. 3 is a flowchart of the liquid crystal screen display consistency correction method provided by the application. Figure 5 The method comprises the following steps:

[0079] In step 310, a full-screen color image and gray-scale longitudinal data are acquired.

[0080] In step 320, a full-screen color feature image information is determined based on the full-screen color image.

[0081] In step 330, full-screen plane correction data are determined based on the color difference value between the full-screen color feature image information and a reference.

[0082] In step 340, the gray-scale longitudinal data are averaged step by step to determine full-screen depth correction data, wherein the step-by-step averaging is used to eliminate the difference between the gray-scale longitudinal data.

[0083] In step 350, the full-screen color image, the full-screen plane correction data and the full-screen depth correction data are sent to a consistency correction end 203.

[0084] Specifically, the measurement end 201 sends the measured full-screen color image and gray-scale longitudinal data to the data processing end 202, and performs plane preliminary correction and depth preliminary correction on the full-screen color image and the gray-scale longitudinal data respectively to meet the requirements of the consistency correction end 203 on the data.

[0085] Optionally, the size of the full-screen color image depends on the number of sensors of the measurement end 201. The area of the sensor is much larger than that of the measurement point of the liquid crystal screen, but much smaller than that of the probe of the color temperature instrument. Therefore, the measured image can meet the basic requirement of the enlarged image and is much smaller than the display data of the liquid crystal screen. For example, taking a liquid crystal screen with a resolution of 1920*1080 as an example, the size of the block data measured by a single sensor is 20*20, and the data amount of the full-screen color image is only 96*54, and a 96*54 RGB color data is formed.

[0086] Optionally, the method for performing plane preliminary correction on the full-screen color image comprises the following steps:

[0087] determine the color minimum value of the limited gray scale in the full-screen color feature image information, and take the color minimum value of the limited gray scale in the full-screen color feature image information as a reference;

[0088] compare all points in the full-screen color feature image information with the reference to determine the color difference value of the full-screen color feature image information and the reference;

[0089] Based on the color difference value, determine the full-screen plane correction data.

[0090] Specifically, the minimum value of the RGB information of the 255th gray scale of all points in the full-screen color feature image information is taken as the reference, and all points are compared with the reference to obtain the RGB difference value of all points exceeding the reference. Based on the RGB difference value of all points exceeding the reference, the data processing end 202 can construct the full-screen plane correction data by scanning imaging, and upload and store the plane data FLASH unit for FPGA calling.

[0091] Optionally, the depth preliminary correction method of the gray scale longitudinal data can be: based on the 0-255 gray scale longitudinal data collected by the measurement end 201, each data can constitute a color gray scale curve of an original image, and the data processing end 202 uses a step-by-step average algorithm to simultaneously perform step-by-step averaging on the 0-255 gray scale longitudinal data to eliminate the difference between the gray scale longitudinal data, and generate a new 0-255 full-screen depth correction data, which is uploaded and stored in the depth data FLASH unit for FPGA calling. In addition, if the liquid crystal screen requires N different GAMMA or DICOM curves, the amount of data stored is 256*N.

[0092] The liquid crystal screen display consistency correction method provided by the application can eliminate color differences by performing plane preliminary correction on full-screen color feature image information, extracting color difference values for subsequent plane correction, and providing rich data for eliminating color differences. In addition, by performing step-by-step averaging on the gray scale longitudinal data, the difference between the gray scale longitudinal data is eliminated, and more average and optimized full-screen depth correction data is provided for subsequent depth correction, and further stereoscopic and comprehensive correction is performed.
