Description

Technical Field

[0001] The present invention relates to the field of image display technology, and in particular to a display control method and device for a display screen. Background Art

[0002] At present, LED display screens are widely used in many fields such as advertising media, sports events, stage rentals and public transportation due to their high brightness, wide viewing angle, bright colors, flexible use and low power consumption. LED display screens are also divided into two different market application modes: rental and fixed installation. Among them, rental display screens can be applied to different venues due to their characteristics of quick installation and disassembly, meeting the display area requirements of different venues. However, for different application venues, the display effect and screen specifications of the display screen are different. In particular, in the above-mentioned application scenarios such as advertising media, sports events, stage rentals and public transportation, a larger display area is often required. In order to increase the display area and meet the usage requirements of different customers and application scenarios, it is usually adopted to splice multiple rental display screens to obtain a large-size display screen after splicing. However, it is difficult to ensure that the light point spacing of each display screen is the same during the splicing process. Sometimes, display screens with different light point spacing are spliced ​​together as an emergency solution. The overall display effect of the spliced ​​screen is poor, and obvious light and dark lines will appear at the splicing, which gives customers a low experience.

[0060] The specific embodiments disclosed in the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0061] Figure 1 is a flow chart of a display control method of a display screen according to an exemplary embodiment. Figure 1 As shown, the method includes:

[0062] In step 101, a display picture to be played is divided into n display sub-pictures according to the display screen resolutions of n display screens.

[0063] For example, in different usage scenarios, it is necessary to select an LED display screen of appropriate size according to the site requirements, or to splice several existing display screens so that the size of the display screen after splicing meets the requirements of different usage scenarios. For example, n rental display screens are spliced ​​together to form a large-size display screen, and there are different light point spacings between the n rental display screens. Because when display screens with different light point spacings are spliced, the display screen at the splicing point is prone to obvious bright and dark lines, thereby affecting the display effect, a display control method for a display screen is provided in the disclosed embodiment of the present invention. In this method, the display screen to be played is divided according to the number of display screens. If n display screens need to be spliced ​​together, the display screen to be played is divided into n display sub-screens, so that the n display sub-screens can be played through the n display screens respectively.

[0064] Figure 2 is based on Figure 1 A flow chart of a method for splitting a display screen to be played is shown in FIG. Figure 2 As shown, step 101 includes:

[0065] In step 1011, each frame of the to-be-played display picture is determined according to the to-be-played video source.

[0066] In step 1012, each frame of the to-be-played display picture is divided into n display sub-pictures according to the display screen resolution of the display screen.

[0067] The image resolution of each display sub-image is the same as the resolution of the corresponding display screen.

[0068] For example, the video source to be played is divided into display pictures to be played according to the video frame, and each frame of the display picture to be played is divided to obtain n display sub-pictures. It can be understood that since each display sub-picture needs to be played on a corresponding display screen, the image resolution of the display sub-picture needs to be adjusted so that the image resolution is the same as the display screen resolution.

[0069] Usually, the display resolutions of different displays are different, so it is necessary to adapt the divided display sub-images to the specifications of the display. Figure 3As shown, when n is 2, the display screens to be spliced ​​are display screen A and display screen B, both of which are 250*250, but the light point spacing in display screen A is 2.6, and the light point spacing in display screen B is 3.9. The split display sub-screens are the first display sub-screen played through display screen A and the second display sub-screen played through display screen B. The number of lights in the first display sub-screen and the second display sub-screen is different, and the degree of refinement of the displayed screen will also be different. The lights in display screen A are arranged as 96*96, so display screen A can display 96*96=9216 screen contents (each light point displays one screen content), and the lights in display screen B are arranged as 64*64, so display screen B can display 64*64=4096 screen contents. The degree of refinement of the screen displayed by display screen A is greater than that of display screen B. In order to prevent the overall display effect of the screen A and display screen B from being affected by the different degrees of refinement of the screen display after splicing, the method of display screen A being backward compatible with display screen B is adopted. Multiple lights in display screen A display the same screen content, reducing the refinement of display screen A, and making the refinement of display screen A and display screen B as consistent as possible, thereby balancing the overall display effect of the spliced ​​screen.

[0070] In step 102, the edge area of ​​the corresponding display sub-picture is determined according to the dot matrix characteristics of each display screen.

[0071] For example, in order to further optimize the display effect at the joint and weaken the impact of the bright and dark lines, it is necessary to perform transition processing on the image at the joint (i.e., the edge area) to reduce the visual abruptness after the joint. The edge area of ​​the display sub-image is determined according to the number of rows and columns of the display screen light points (i.e., the dot matrix characteristics), so as to further process the display image in the edge area (preferably fusion processing in the disclosed embodiment of the present invention).

[0072] Figure 4 is based on Figure 1 A flow chart of a method for determining an edge region is shown in FIG. Figure 4 As shown, step 102 includes:

[0073] In step 1021, the position of the edge region in each display sub-picture is determined according to the relative position relationship between the display screens.

[0074] For example, according to the relative position relationship between the spliced ​​screens, the display sub-screen portion corresponding to the spliced ​​portion is determined as the edge area, that is, the position of the edge area is determined. Figure 3 , Figure 5 and Figure 6 As shown, it indicates the positions of different edge areas corresponding to different relative position relationships during the splicing process of the display screen. Figure 3The relative position relationship between the display screen A and the display screen B is left-right splicing, and the splicing area between the display screen A and the display screen B is the edge area; Figure 5 The relative position relationship between the middle display screen C and the display screen D is that they are spliced ​​up and down, and the splicing point between the display screen C and the display screen D is the edge area; Figure 6 The middle display screen E is spliced ​​with the display screen F and the display screen G up and down, respectively, and the display screen F and the display screen G are spliced ​​left and right, so the edge area is the splicing point of the three display screens.

[0075] In step 1022, the number of rows and / or columns of light points corresponding to the edge area in each display sub-picture is determined according to the number of rows x and / or columns y of light points in each display screen and the light point spacing.

[0076] The dot matrix characteristics are the number of rows x and / or columns y containing light dots in the display screen and the distance between the light dots.

[0077] For example, after determining the position of the edge region, it is also necessary to determine the number of rows and / or columns of light points contained in each edge region according to the dot matrix characteristics. It is understandable that Figure 3 The edge area represented by includes a number of columns of light points, and the number of columns of light points included in each edge area needs to be determined according to the number of columns of light points y included in the display screen; Figure 5 The edge area represented by includes a number of rows of light points, and the number of rows of light points included in each edge area needs to be determined according to the number of rows of light points x included in the display screen; Figure 6 The number of light point columns contained in the edge area represented needs to be determined according to the number of light point columns y contained in the display screen, and the number of light point rows contained needs to be determined according to the number of light point rows x contained in the display screen.

[0078] Specifically, the method determines the number of rows and / or columns of light points corresponding to the edge area of ​​each display sub-screen according to the number of rows x and / or columns y of light points in each display screen and the light point spacing, including: judging whether the light point spacing of the display screen is greater than 5; if the light point spacing is greater than 5, determining that the number of rows of light points in the edge area corresponding to the display screen is x / 3, and / or the number of columns is y / 3; if the light point spacing is less than or equal to 5, determining that the number of rows of light points in the edge area corresponding to the display screen is x / 2, and / or the number of columns is y / 2.

[0079] In step 103, the edge area of ​​each display sub-picture is fused according to the display requirements after splicing to obtain the picture to be played.

[0080] For example, the fusion processing technology is a technology for overlapping and aligning pixel points in edge areas of n display sub-pictures, and the display sub-picture after the fusion processing is the picture to be played.

[0081] In step 104, the corresponding picture to be played is played through the display screen, and the brightness, contrast and color of the picture to be played are adjusted to control the display effect of the display screen.

[0082] Specifically, the brightness, contrast and color of the picture to be played on each display screen are measured; based on the brightness measurement result, the brightness of the picture to be played on each display screen is made consistent with the principle of compatibility of high-brightness display screens with low-brightness display screens; based on the contrast measurement result, the contrast of the picture to be played on each display screen is made consistent; based on the color measurement result, the color of the picture to be played on each display screen is made consistent.

[0083] For example, the calibration function of the display control system is combined with the information fed back by the environmental detection sensor to fine-tune the color, brightness and contrast of the display screen to achieve the best matching effect. Specifically, the brightness of the display screen is tested by the sensor to make the brightness of each display screen consistent. When the brightness of the display screen is inconsistent, the display screen with high brightness is downward compatible with the display screen with low brightness. Then adjust the contrast of the display screen to make each display screen as consistent as possible in the same color state (contrast enhancement technology can be used, such as dynamic contrast adjustment, to optimize the display effect of the display screen). Correct the color of the display screen. The color gamut and brightness of the display screen may differ from the video source to be played. These differences need to be corrected during the image processing process to ensure the color consistency of the image on the display screen and improve the color restoration of the picture to be displayed.

[0084] Optionally, the display screen is a display screen using a matrix integrated packaging solution. The matrix integrated packaging solution (Integrated Matrix Devices, referred to as IMD) is a display screen that integrates and packages several groups of RGB lamp beads in a small unit, that is, a display screen using N-in-1 lamp beads (N can be 3, 4, 5, 6, etc.), and displays in the form of virtual pixels.

[0085] Figure 7 is based on Figure 1 A flow chart of a method for judging before display screen splicing is shown in FIG. Figure 7 As shown, the method includes:

[0086] In step 701, the light point spacings of n display screens are sorted, and the display screen with the median light point spacing is set as the reference display screen.

[0087] Among them, the light point spacing of the reference display screen is m.

[0088] In step 702, it is confirmed whether the distance between the lamp points of (n-1) display screens excluding the reference display screen is between 0.5 m and 2 m.

[0089] In step 703, if yes, a splicing operation is performed on the n display screens.

[0090] For example, in order to ensure the display effect of the screen after splicing, the difference between the light point spacings of the display screen is limited. If the difference in the light point spacings is too large, the display screen will not be spliced. After determining n display screens, the light point spacings of each display screen are obtained and sorted. For example, n is 5, and the light point spacings of the n display screens are 2, 2, 2.5, 3, and 3, respectively. The median of these 5 light point spacings is 2.5, then m is 2.5, and the corresponding display screen is the reference display screen. At this time, the values ​​of 0.5m to 2m are 1.25 to 5. If the light point spacings of the remaining (n-1) display screens are within this range, the n display screens can be spliced. It can be seen that the light point spacings of the remaining (n-1) display screens are 2, 2, 3, and 3, respectively, which are all within the numerical range of 1.25 to 5, and the above 5 display screens can be spliced. In this way, the difference in the distance between the lights of the display screens used in the splicing process is limited, and the difference in the fineness of the displayed images between the display screens is controlled within a certain range, which can ensure that the displayed images on the spliced ​​screens are as consistent as possible, or the differences are not obvious, further improving the overall display effect of the spliced ​​screens.
