Referring to fig. 3, a flowchart of steps of a tiled screen display method according to an embodiment of the present invention is shown. The tiled screen display method shown in fig. 3 can be applied to a fusion driver.
As shown in fig. 3, the tiled screen display method may include the steps of:
step 301, a video to be displayed is received.
After receiving the original video stream, the splicing controller displays the original video stream into a splicing screen, and processes the original video stream according to the splicing mode (such as 2×2 splicing, 3×3 splicing and the like) and the attribute parameters of the size and the like of the splicing screen to generate a spliced video signal which can be displayed in the splicing screen, wherein the spliced video signal is the video to be displayed.

Therefore, in the video displayed by the spliced screen, the position of the spliced seam is not a black gap, but the color synchronous with the color of the video is displayed, so that the display effect of the spliced screen can be improved, and the watching experience of a user is improved.
Referring to fig. 4, a flowchart of steps of another tiled screen display method according to an embodiment of the present invention is shown. The tiled screen display method shown in fig. 4 can be applied to a fusion driver.
As shown in fig. 4, the tiled screen display method may include the steps of:
step 401, receiving a video to be displayed.
Step 402, determining, based on the color corresponding to the video to be displayed, a respective corresponding color of each light emitting element when the video to be displayed is displayed by using the spliced screen.
Step 403, driving each light emitting element to display its corresponding color.
In the embodiment of the invention, in order to ensure that the color of the light-emitting element and the color of the video to be displayed are synchronously displayed, the video source which is referred to when the color of the light-emitting element is determined is required to be consistent with the video source displayed on the spliced screen, so that the display color of the light-emitting element and the color of the video displayed on the spliced screen are synchronously displayed, and the fusion of the display of the light-emitting element and the video display is realized. Therefore, the video to be displayed needs to be synchronously sent to the mosaic screen and the fusion driver by the mosaic controller. After the spliced screen receives the video to be displayed, each frame of image of the video to be displayed is sequentially analyzed and displayed. After receiving the video to be displayed, the fusion driver sequentially analyzes each frame of image of the video to be displayed, determines the corresponding color of each light-emitting element when the current image is displayed, and drives each light-emitting element to display the corresponding color after determining the color.
Based on the color corresponding to the video to be displayed, the process of determining the color corresponding to each light-emitting element when the video to be displayed is displayed by using the spliced screen specifically may include: and determining the respective corresponding color of each light-emitting element when the current image is displayed by utilizing the spliced screen based on the corresponding color of the current image aiming at each frame of image in the video to be displayed.
In an alternative embodiment, the process of determining the respective corresponding color of each light emitting element when the current image is displayed by using the tiled screen based on the corresponding color of the current image may include the following steps A1-A2:
step A1 of determining, for each light emitting element, a pixel covered by the current light emitting element when the current image is displayed with the stitched screen.
When the current image is displayed by using the mosaic screen, a part of pixels in the current image may be covered by the mosaic seams in the mosaic screen. Accordingly, the color corresponding to the pixel covered by the light emitting element can be displayed by the light emitting element in the splice line so as to replace the color of the pixel covered by the light emitting element.
In an alternative embodiment, the process of determining the pixels covered by the current light emitting element when the current image is displayed using the tiled screen may include the following steps a 11-a 13:
And step A11, acquiring the coordinate position of the splicing seam area where the current light-emitting element is positioned.
For each splice seam in the splice screen, the splice seam can be divided into a plurality of splice seam areas of a preset size, and a light-emitting element is arranged in each splice seam area. For example, the light emitting element is an LED lamp bead, and then an LED lamp strip can be disposed in each splice seam, that is, the LED lamp strip is adhered to the splice seam, and the size of the LED lamp strip is the same as that of the splice seam where the LED lamp strip is located, so that an LED lamp bead is disposed in each preset size area of the LED lamp strip.
Optionally, according to the actual situation of the site, the attribute parameters of the spliced screen where the light-emitting elements connected with the fusion driver are located are preset in the fusion driver. Wherein the attribute parameters may include: the size of each individual screen in the spliced screen (the size of the individual screen may include a lateral size, a longitudinal size, etc.), the position of each individual screen in the spliced screen (the position of the individual screen may include a line of the spliced screen, a column of the spliced screen, etc.), the size of each splice seam (the size of the splice seam may include a lateral size, a longitudinal size, etc.), the position of each splice seam in the spliced screen (the position of the splice seam may include a space between two individual screens of a line of the spliced screen, etc.), the density of the light-emitting element arrangement (the density may include the size of the splice seam area occupied by one light-emitting element, the size may include a lateral size, a longitudinal size, such as the above-mentioned preset size, etc.), and the like.
The fusion driver can perform coordinate calculation on the light-emitting elements according to the attribute parameters, so that the coordinate positions of the splicing seam areas where the light-emitting elements are located are obtained.
For example, the lower left corner position of the stitched screen may be taken as the origin. The coordinate position of each splice seam can be calculated according to the size of each independent screen in the splice screen, the position of each independent screen in the splice screen, the size of each splice seam and the position of each splice seam in the splice screen, and the coordinate position of each splice seam can comprise the coordinate positions of four vertexes of the splice seam. According to the coordinate position of each splice seam and the set density of the light emitting elements (i.e., the preset size), the coordinate position of each splice seam region may be calculated, and the coordinate position of each splice seam region may include the coordinate positions of four vertices of the splice seam region.
And step A12, dividing the current image into a plurality of image areas with preset sizes, and acquiring the coordinate position of each image area.
Corresponding to the mode of dividing the splicing seam into a plurality of splicing seam areas with preset sizes and arranging one light-emitting element in each splicing seam area, the current image to be displayed in the splicing screen can be divided into a plurality of image areas with preset sizes according to the size of the splicing screen, and the coordinate position of each image area is obtained.
For example, the lower left corner of the stitched screen may be used as an origin, and the coordinate position of each image area may be calculated according to the above-mentioned preset sizes (such as the lateral size and the longitudinal size). The coordinate locations of the image region may include coordinate locations of four vertices of the image region.
And A13, selecting an image area with the coordinate position overlapped with the coordinate position of the splicing seam area where the current light-emitting element is positioned, and taking the pixels contained in the selected image area as the pixels covered by the current light-emitting element.
The predetermined size may include a lateral dimension and a longitudinal dimension. For the specific values of the preset values, any applicable values can be selected according to practical experience, and the embodiment of the invention is not limited to this. For example, the transverse dimension of the preset size may be 1 mm, the longitudinal dimension 1 mm, and the area 1 square mm.
And step A2, determining the color corresponding to the current light-emitting element when the current image is displayed by using the spliced screen based on the color of the pixel covered by the current light-emitting element.
After determining the pixel covered by the current light emitting element, the color corresponding to the current light emitting element can be determined based on the color of the pixel covered by the current light emitting element.
In an alternative embodiment, the process of determining the color corresponding to the current light emitting element when the current image is displayed using the tiled screen based on the color of the pixel covered by the current light emitting element may include the following steps a21 to a22:
and step A21, respectively acquiring the respective RGB (Red, green, blue, red, green and blue) color values of each pixel covered by the current light-emitting element.
And step A22, calculating the average RGB color value of all pixels covered by the current luminous element, and taking the average RGB color value as the corresponding color of the current luminous element.
When the color corresponding to the current image is determined and the current image is displayed by using the spliced screen, the fusion driver can drive each light-emitting element to display the corresponding color respectively. Therefore, the spliced screen can display the current image and simultaneously the light emitting elements can respectively display the colors synchronous with the current image.
And step 404, acquiring the brightness of the spliced screen when the video to be displayed is displayed by using the spliced screen.
Step 405, determining the brightness corresponding to each light emitting element based on the brightness of the spliced screen.
Step 406, each light emitting element is driven to display its corresponding brightness.
In the embodiment of the present invention, the fusion driver may drive the light emitting element to perform color display by using the methods from step 401 to step 403, and may also drive the light emitting element to perform brightness adjustment by using the methods from step 404 to step 406.
When the video to be displayed is displayed by using the spliced screen, the fusion driver can acquire the brightness of the spliced screen. In an alternative embodiment, the process of obtaining the brightness of the spliced screen when the video to be displayed is displayed by using the spliced screen may include: and for each splice joint, regularly acquiring the brightness of a part of the splice screen which is positioned at two sides of the current splice joint and has the same size as the current splice joint when the video to be displayed is displayed by using the splice screen, and taking the brightness of the part of the splice screen corresponding to the current splice joint as the brightness of the part of the splice screen. For the time interval for obtaining the brightness, any suitable value may be set according to practical experience, which is not limited in the embodiment of the present invention. For example, the time interval may be set to 5 seconds, 10 seconds, 15 seconds, and so on.
After each acquisition of the brightness of the spliced screen, the respective brightness of each light emitting element may be further determined. In an alternative embodiment, the process of determining the respective brightness of each light emitting element based on the brightness of the spliced screen may include: for each splice seam, determining the respective brightness of each light-emitting element in the current splice seam based on the brightness of the partial spliced screen corresponding to the current splice seam.
In an alternative embodiment, elements for detecting brightness, such as an optical resistor and a brightness sensor, may be installed at the screen positions at two sides of the joint, and the brightness of the partial joint screen located at two sides of the current joint and having the same size as the current joint may be obtained by using these elements to serve as the brightness of the partial joint screen corresponding to the current joint. Then, an average value of the luminance of the partial tiled screen corresponding to the current tiled seam is calculated, and the average value is taken as the luminance corresponding to each light-emitting element in the current tiled seam. Alternatively, considering that the length of the splice seam may be long, the splice seam may be divided into multiple segments, and each segment of splice seam is separately calculated, and based on the brightness of the partial splice screen located at both sides of the segment of splice seam and having the same size as the segment of splice seam, the brightness of each light emitting element in the segment of splice seam is calculated.
In an alternative embodiment, image pick-up devices may be installed at the positions of the screens at two sides of the joint, the current joint is collected by using the image pick-up devices, and the images of the partial joint screens with the same size as the current joint are located at two sides of the current joint, and the respective corresponding brightness of each light emitting element in the current joint is calculated according to the brightness of the current joint in the collected images and the brightness of the partial joint screens with the same size as the current joint.
After determining the respective brightness of each light emitting element, the fusion driver can drive each light emitting element to display the respective brightness so as to adjust the brightness of the light emitting element to be similar to the brightness of the adjacent spliced screen.
In the embodiment of the invention, the light-emitting elements are matched with the screen display, the corresponding color of each light-emitting element is calculated based on the correspondence between the video image and the position of the light-emitting element, the light-emitting element is driven to display the color synchronous with the video image, and the fusion of the color displayed by the light-emitting element and the video displayed by the spliced screen is realized, so that the influence of the splicing seam on the video picture display is reduced, and the display effect is improved. And the brightness of the light-emitting element can be adjusted based on the brightness of the spliced screen display, so that the display effect is further improved. Meanwhile, the spliced screen is not required to be modified, compared with a reduced screen frame, the cost of the light-emitting element is greatly reduced, so that the splice joint influence of the spliced screen is eliminated through lower cost, and the overall viewing experience is improved.
