Description

Technical Field

[0001] This application relates to the field of display technologies, and in particular, to an image display method and a tiled display device. Background Art

[0002] With the development of the display industry, people's demand for large-sized display screens has increased. Since it is difficult to mass-produce large-sized display screens, seamless tiling technology has emerged as the times require. Seamless tiling technology uses multiple small-sized display units to tile into a large-sized display screen. Since there are borders on the display units and no images can be displayed at the borders, there will be a shadow at the junction of two display units. In related technologies, another display module is provided at the junction of two display units. The display module can be a zero-border display product such as a Mini-led panel, which is used to cover the shadow. However, after tiling, it can only ensure that there is no shadow when observed from the front view angle at the junction, and a shadow can still be observed at the side view angle, which affects the display effect.

[0042] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the protection scope of the present application. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the orientation terms such as "upper" and "lower" generally refer to the upper and lower in the actual use or working state of the device, specifically the drawing direction in the drawings; and "inner" and "outer" refer to the outline of the device.

[0043] The present application provides an image display method, which is applied to the splicing display device 30. The splicing display device 30 includes at least two first display units 10 and a second display unit 20 disposed on the two first display units 10. The second display unit 20 covers the seam between the two first display units 10. The display areas of the first display unit 10 and the second display unit 20 partially overlap in the light-emitting direction of the splicing display device 30. The image display method includes:

[0044] S10, obtaining the first resolution of the first display unit 10 and the second resolution of the second display unit 20;

[0045] S20, according to the first resolution and the second resolution, intercepting the image frame 21 to be displayed into a first display image 22 matching the first resolution and a second display image 23 matching the second resolution;

[0046] S30, transfer the data of the first display image 22 to the first display unit 10, and transfer the data of the second display image 23 to the second display unit 20.

[0047] In this embodiment, the first display unit 10 may be an LCD panel, and the second display unit 20 may be a Mini-led panel, but is not limited thereto.

[0048] The display surfaces of the first display unit 10 and the second display unit 20 are on the same side. Taking the first display unit 10 as an LCD panel and the second display unit 20 as a Mini-led panel as an example for illustration. The border width of the Mini-led panel is smaller than that of the LCD panel. By setting the Mini-led panel on the seam between two adjacent LCD panels, normal display can be achieved at the seam, thus realizing seamless splicing. In the front view, the image displayed at the seam is the image of the Mini-led panel.

[0049] In this embodiment, the display area of the first display unit 10 includes a plurality of pixels, and the display area of the second display unit 20 includes a plurality of pixels. The partial overlap of the display areas of the first display unit 10 and the second display unit 20 in the light-emitting direction of the splicing display device 30 means that the orthographic projection of the display area of the second display unit 20 on the first display unit 10 overlaps with the display area of the first display unit 10.

[0050] Since the display areas of the first display unit 10 and the second display unit 20 overlap in the splicing direction, therefore, when viewed from the side, the pixels of the first display unit 10 adjacent to the second display unit 20 emit light, which can avoid the shadow when viewed from the side.

[0051] The splicing direction refers to the direction in which the first display units 10 arranged on both sides of the second display unit 20 are arranged.

[0052] In step S10, the first resolution includes the row resolution and column resolution of the first display unit 10. The row resolution is the number of pixels in the row direction, and the column resolution is the number of pixels in the column direction.

[0053] The second resolution includes the row resolution and column resolution of the second display unit 20. The row resolution is the number of pixels in the row direction, and the column resolution is the number of pixels in the column direction.

[0054] It should be noted that in this application, the splicing display device 30 is taken as an example of 2*1 splicing for illustration, that is, the splicing display device 30 includes two first display units 10 and one second display unit 20, and the two first display units 10 are spliced along the row direction. In order to ensure the continuity of the spliced image, the number of pixels of the first display unit 10 in the row direction matches the number of pixels of the second display unit 20 in the row direction.

[0055] For example, when the first resolution is 1920*1080, the second resolution can be 40*1080, so as to achieve 1080 rows of pixels for both.

[0056] In step S20, the image frame 21 to be displayed can be sourced from a video source. The video source provides the image frame to be displayed to the splicing display device 30.

[0057] The image frame 21 to be displayed is intercepted as the first display image 22, and the first display image 22 matches the first resolution. That the first display image 22 matches the first resolution means that the resolution of the first display image 22 is the same as or equivalent to the first resolution, so that the first display image 22 can be completely displayed.

[0058] The image frame 21 to be displayed is intercepted as the second display image 23, and the second display image 23 matches the second resolution. That the second display image 23 matches the second resolution means that the resolution of the second display image 23 is the same as or equivalent to the second resolution, so that the second display image 23 can be completely displayed.

[0059] It should be understood that the order of intercepting the first display image 22 and the second display image 23 is not limited. It can be intercepted simultaneously or sequentially. When intercepted sequentially, the first display image 22 can be intercepted first and then the second display image 23, or the second display image 23 can be intercepted first and then the first display image 22.

[0060] In step S30, the data of the first display image 22 is transmitted to the first display unit 10. The data transmission method can be a High Definition Multimedia Interface (HDMI) cable, but is not limited thereto.

[0061] The data of the second display image 23 is transmitted to the second display unit 20. The data transmission method can be a network cable or the like, but is not limited thereto.

[0062] In the image display method of the present application, step S20 includes:

[0063] S21, obtaining the image frame 21 to be displayed and the third resolution of the splicing display device 30;

[0064] S22, processing the image frame 21 to be displayed into a target image frame that matches the third resolution according to the third resolution;

[0065] S23. Crop the target image screen into a first display image 22 that matches the first resolution and a second display image 23 that matches the second resolution according to the first resolution and the second resolution.

[0066] In step S21, the third resolution of the splicing display device 30 refers to the resolution of the area of the spliced and displayable screen. It should be noted that since the display areas of the first display unit 10 and the second display unit 20 partially overlap in the light-emitting direction, the display area of the first display unit 10 blocked by the second display unit 20 is an invalid display area, and the invalid display area should be excluded when calculating the third resolution.

[0067] In step S22, making the image screen 21 to be displayed into a target image screen that matches the third resolution means that the resolution of the target image screen is the same as or comparable to the third resolution, so that the target image screen can be completely displayed.

[0068] In step S23, crop the target image screen into the first display image 22 and the second display image 23. Since the third resolution excludes the invalid display area of the first display unit 10, the number of pixels of the target image in the splicing direction is less than the total number of pixels of the first display unit 10 and the second display unit 20 in the splicing direction. Therefore, when cropping the first display image 22 and the second display image 23, the first display image 22 and the second display image 23 need to crop the overlapping content at the junction, that is, the first display image 22 and the second display image 23 overlap at the junction.

[0069] In the image display method of the present application, step S21 includes:

[0070] S211. Obtain the number of pixels of the first display unit 10 in the splicing direction according to the first resolution and the second resolution, and obtain the number of pixels of the second display unit 20 in the splicing direction.

[0071] S212. Obtain the number of overlapping pixels of the display area of the first display unit 10 and the display area of the second display unit 20 in the splicing direction.

[0072] S213. Obtain the number of pixels of the splicing display device 30 in the splicing direction according to the number of pixels of the first display unit 10 in the splicing direction, the number of pixels of the second display unit 20 in the splicing direction, and the number of overlapping pixels of the display area of the first display unit 10 and the display area of the second display unit 20 in the splicing direction.

[0073] S214. Obtain the third resolution according to the number of pixels of the splicing display device 30 in the splicing direction.

[0074] In step S211, the number of pixels of the first display unit 10 in the splicing direction is obtained according to the first resolution. The first resolution includes a row resolution and a column resolution. When the splicing direction is the row direction, the number of pixels of the first display unit 10 in the splicing direction is the number of pixels corresponding to the column resolution; when the splicing direction is the column direction, the number of pixels of the first display unit 10 in the splicing direction is the number of pixels corresponding to the row resolution.

[0075] Similarly, the number of pixels of the second display unit 20 in the splicing direction is obtained according to the second resolution. The second resolution includes a row resolution and a column resolution. When the splicing direction is the row direction, the number of pixels of the second display unit 20 in the splicing direction is the number of pixels corresponding to the column resolution; when the splicing direction is the column direction, the number of pixels of the second display unit 20 in the splicing direction is the number of pixels corresponding to the row resolution.

[0076] In step S212, during splicing, the second display unit 20 is located on the first display unit 10, and the display area of the second display unit 20 overlaps with the display area of the first display unit 10. Therefore, some pixels in the display area of the first display unit 10 are blocked and become an invalid display area.

[0077] Obtaining the number of overlapping pixels of the display area of the first display unit 10 and the display area of the second display unit 20 in the splicing direction is to obtain the number of pixels of the invalid display area in the splicing direction.

[0078] In step S213, for the sake of convenience of description, assume that the number of pixels of the first display unit 10 in the splicing direction is X1, the number of pixels of the second display unit 20 in the splicing direction is X2, and the number of overlapping pixels of the display area of the first display unit 10 and the display area of the second display unit 20 in the splicing direction is A. According to X1, X2, and A, the number of pixels of the splicing display device 30 in the splicing direction can be obtained as 2*X1 + X2 - A.

[0079] In step S214, according to the number of pixels 2*X1 + X2 - A of the splicing display device 30 in the splicing direction, a third resolution is obtained. The row resolution of the third resolution is 2*X1 + X2 - A, and the column resolution of the third resolution is equal to the column resolution of the first display unit 10.

[0080] In the image display method of the present application, step S22 includes:

[0081] S221, obtaining the number of pixels of the splicing display device 30 in the splicing direction;

[0082] S222. Process the image frame 21 to be displayed into a target image frame according to the number of pixels of the tiled display device 30 in the tiling direction. The number of pixels of the target image frame in the tiling direction is equal to the number of pixels of the tiled display device 30 in the tiling direction.

[0083] In step S221, referring to step S21, obtain the number of pixels 2*X1 + X2 - A of the tiled display device 30 in the tiling direction.

[0084] In step S222, process the image to be displayed into a target image frame according to the number of pixels 2*X1 + X2 - A of the tiled display device 30 in the tiling direction. That is, after processing, the number of pixels of the target image frame in the tiling direction is equal to 2*X1 + X2 - A. It should be understood that the number of pixels of the target image frame in the non-tiled direction is equal to the number of pixels corresponding to the column resolution of the first display unit 10.

[0085] In the image display method of the present application, step S23 includes:

[0086] S231. Crop the target image frame into a first display image 22 and a second display image 23. The number of pixels of the first display image 22 in the tiling direction is equal to the number of pixels of the first display unit 10 in the tiling direction; the number of pixels of the second display image 23 in the tiling direction is equal to the number of pixels of the second display unit 20 in the tiling direction, and the first display image 22 and the second display image 23 partially overlap in the tiling direction.

[0087] In step S231, the number of pixels of the first display image 22 in the tiling direction is equal to X1, the number of pixels of the second display image 23 in the tiling direction is equal to X2, and the first display image 22 and the second display image 23 partially overlap in the tiling direction, and the number of overlapping pixels is A.

[0088] It should be noted that since the seam is strip-shaped, the shape of the second display unit 20 is also strip-shaped to cover the seam. The long side of the second display unit 20 is perpendicular to the tiling direction, and the short side of the second display unit 20 is parallel to the tiling direction.

[0089] One column or multiple columns of pixels in the first display image 22 are blocked by the second display unit 20, that is, the long side of the second display unit 20 extends along the column direction.

[0090] In the image display method of the present application, the number of overlapping pixels of the first display image 22 and the second display image 23 in the tiling direction is the same as the number of overlapping pixels of the first display unit 10 and the second display unit 20 in the tiling direction.

[0091] In this embodiment, the number of overlapping pixels of the first display image 22 and the second display image 23 in the splicing direction is A, and the number of overlapping pixels of the first display unit 10 and the second display unit 20 in the splicing direction is also the same, which is A. Through the above settings, the first display image 22 and the second display image 23 can display the same content in the overlapping area, so as to ensure the continuity and integrity of the front view image. At the same time, it can also avoid the shadow under the side view angle.

[0092] Optionally, the number of overlapping pixels of the second display unit 20 with the two first display units on both sides is equal, both being A / 2, but not limited to this.

[0093] In some embodiments, the size and arrangement of the pixels of the first display unit 10 are the same as those of the pixels of the second display unit 20, so that the transition between the first display image 22 and the second display image 23 is natural.

[0094] Optionally, the size and arrangement of the pixels of the first display unit 10 are different from those of the pixels of the second display unit 20, so that the second display unit 20 can be compatible with the first display units 10 with various different pixel specifications.

[0095] In the image display method of the present application, each second display unit 20 includes two boundary lines extending perpendicular to the splicing direction. At least two rows of pixels in the first display unit 10 adjacent to the second display unit 20 display the same content, and the two rows of pixels displaying the same content are respectively located on both sides of the same boundary line of the second display unit 20.

[0096] In this embodiment, each second display unit 20 includes two boundary lines extending perpendicular to the splicing direction. At least two rows of pixels in the first display unit 10 adjacent to the boundary line of the second display unit 20 display the same content. That is to say, when the first display unit 10 is spliced in the row direction, at least two columns of pixels in the first display unit 10 adjacent to the boundary line of the second display unit 20 display the same content. When the first display unit 10 is spliced in the column direction, at least two rows of pixels in the first display unit 10 adjacent to the boundary line of the second display unit 20 display the same content.

[0097] Further, the two rows of pixels with the same content are respectively located on both sides of the same boundary line of the second display unit 20. That is to say, at least one row of pixels among the two rows of pixels with the same content is not blocked by the second display unit 20. Through the above settings, the requirement for splicing accuracy can be reduced. Even if the second display unit 20 blocks one row of pixels due to splicing deviation, the row of pixels not blocked displays the same content as the blocked row of pixels, so as to still ensure the continuity and integrity of the front view image.

[0098] In the image display method of the present application, step S30 includes:

[0099] S31, sending the first display image 22 to the first output terminal, and the first output terminal transmits the data of the first display image 22 to the first display unit 10;

[0100] S32, sending the second display image 23 to the second output terminal, and the second output terminal transmits the data of the second display image 23 to the second display unit 20.

[0101] In step S31, the first output terminal can adopt HDMI output.

[0102] In step S32, the second output terminal can adopt network port output.

[0103] The first output terminal and the second output terminal output synchronously, and the first display image 22 and the second display image 23 match to jointly form a target image screen.

[0104] In the image display method of the present application, before step S30, it further includes:

[0105] S40, processing the first display image 22 to increase the gray level of at least one row of pixels adjacent to the second display unit 20 in the first display unit 10.

[0106] Since the side wall of the second display unit 20 cannot emit light, the side wall of the second display unit 20 is easily observed during side viewing, that is, the shadow during side viewing. Although overlapping the display area of the first display unit 10 with the display area of the second display unit 20 can improve the shadow problem to a certain extent. However, the side wall of the second display unit 20 is likely to block light, making the light of the pixels in the display area of the first display unit 10 insufficient to compensate for the shadow.

[0107] In view of this, in step S40, the first display image 22 is processed to increase the gray level of at least one row of pixels adjacent to the long side of the second display unit 20 in the first display unit 10. The way of increasing the gray level can be to increase the gray level by 1 - 10 as a whole, so as to enhance the brightness of the pixels in the first display unit 10 adjacent to the long side of the second display unit 20 and further improve the side viewing shadow.

[0108] The way of increasing the gray level can also be adjusted according to the actual effect, and the present application does not limit this.

[0109] The present application further provides a splicing display device 30. The splicing display device 30 at least includes two first display units 10 and a second display unit 20 disposed on the two first display units 10. The second display unit 20 covers the seam between the two first display units 10. The display areas of the first display unit 10 and the second display unit 20 partially overlap in the light-emitting direction of the splicing display device 30. The splicing display device 30 includes:

[0110] An acquisition module 31, configured to acquire a first resolution of the first display unit 10 and a second resolution of the second display unit 20;

[0111] A truncation module 32, configured to truncate the image frame 21 to be displayed into a first display image 22 matching the first resolution and a second display image 23 matching the second resolution according to the first resolution and the second resolution;
