For example, a large-screen display device formed by splicing 4 display devices is configured as shown in fig. 1, wherein a plurality of backlights are configured in a frame of each display device screen, a gap formed by frames of adjacent display device screens is compensated by the backlights configured in the frames of the 4 display devices, and the influence of the gap on the display effect of the spliced large-screen display device is weakened.
The embodiment of the invention provides an image display method, which is applied to a large-screen display device formed by splicing a plurality of display devices, wherein a plurality of background lamps are configured in a frame of any one of the plurality of display devices, and the method is executed by the plurality of display devices in parallel. The flow of the method is shown in fig. 2, and comprises the following steps:
step 201: the method comprises the steps of obtaining a sub-image used for being displayed on a first display device in an image to be displayed, wherein the first display device is any one of a plurality of display devices.
Step 202: according to a plurality of sampling areas set in a screen of the first display device, extracting color values of pixels of the sub-image in each sampling area, wherein one sampling area corresponds to a backlight configured in a frame of the first display device, and the sampling area corresponding to one backlight comprises an area covered by the backlight at a corresponding position of a border area of the screen of the first display device.
Specifically, the sampling region corresponding to the backlight 301 is a rectangular region including a region covered by the backlight 301 at a corresponding position of the edge of the screen (i.e. the display region) in the first display device, as shown in fig. 3, the sampling region may be larger than the region covered by the backlight 301 at a corresponding position of the edge of the screen in the first display device, where a circle in the frame of the first display device represents the backlight configured on the frame of the first display device, a gray region represents the edge region of the screen of the first display device, and d1Representing the width of the screen edge area in the horizontal direction in the first display device, d2The width of the screen in the vertical direction of the edge region of the screen in the first display device is indicated, W indicates the width of the screen in the first display device, H indicates the height of the screen in the first display device, the dotted circle in the sampling region corresponding to the backlight 301 indicates the region covered by the backlight 301 at the corresponding position of the displayable region edge in the first display device, and the size of the dotted circle is the same as the size of the backlight 301. The width in the horizontal direction and the width in the vertical direction of the screen edge area in the first display device are preset values that are empirically determined, for example, the width d in the horizontal direction of the screen edge area in the first display device11/8 for the height H of the screen of the first display device, the width d of the edge area of the screen in the first display device in the vertical direction21/8, the first display device screen width W.
In an implementation, the plurality of sampling regions set in the screen of the first display device are all or part of the sampling regions set in the screen of the first display device. In the primary image display process, the more sampling regions are used, the more backlights are used to compensate for a gap with an adjacent display device when the sub image is displayed on the first screen, and the better the compensation effect is. For example, the first display device is provided with N sampling regions in the screen, the N sampling regions are respectively numbered as 1,2, …, and N, when the first display device displays a current video frame in a video frame sequence, the gap between the first display device and an adjacent display device is compensated by the backlights corresponding to the sampling regions numbered as odd numbers, and when the first display device displays a next video frame, the gap between the first display device and the adjacent display device is compensated by the backlights corresponding to the sampling regions numbered as even numbers, so that the backlights corresponding to the sampling regions numbered as odd numbers and the backlights corresponding to the sampling regions numbered as even numbers in the first display device are alternately in an operating state during the display of the video frame sequence, and the service life of the backlights is prolonged.
Step 203: and respectively determining the display information of the background light corresponding to each sampling area according to the color value of the pixel in each sampling area.
Wherein the display information comprises color values and/or luminance values.
In implementation, according to a color value of a pixel in each sampling region, display information of a backlight corresponding to each sampling region when the first display device displays the sub-image is respectively determined, wherein the sampling region corresponding to one backlight comprises a region covered by the backlight at a corresponding position of a screen edge region of the first display device, so that when the first display device displays the sub-image, a color of the backlight corresponding to the sampling region is close to a color of the backlight at a corresponding position of the edge of a displayable region of the first display device, and transition of the sub-image displayed by two adjacent display devices is natural.
Specifically, if the display information of the backlight includes a color value, for any one sampling region, the color value of the backlight corresponding to the sampling region may be determined by, but is not limited to, the following two methods:
the method comprises the steps of determining an average value of color values of all pixels in the sampling area, and determining color values of background lights corresponding to the sampling area according to the average value.
And secondly, determining the weight corresponding to each pixel according to the distance from each pixel in the sampling region to the backlight corresponding to the sampling region, calculating a weighted average value according to the weight corresponding to each pixel and the color value of each pixel, and determining the color value of the backlight corresponding to the sampling region according to the weighted average value.
If the display information of the backlight comprises a brightness value, for any sampling region, the brightness value of the backlight corresponding to the sampling region can be determined by the following method: and respectively determining the brightness value of each pixel according to the color value of each pixel in any sampling region, and determining the brightness value of the background light corresponding to the sampling region according to the average value of the brightness values of each pixel.
In a specific embodiment, for any one sampling region, if a color value of a pixel in the sampling region is an RGB value, the RGB value of the pixel is converted into a YUV value, where a Y value is a luminance value of the pixel.
Step 204: and displaying the subimage, and setting a corresponding background light in the first display device according to the determined display information of the background light.
In implementation, if a plurality of display devices for screen splicing are connected with one image display control device, the backlights in the frames of the display devices can be controlled in a centralized manner, so that gaps in the large-size display devices formed by splicing are compensated through the backlights configured in the frames of each display device, the influence of the gaps on the display effect of the large-size display devices is weakened, and the display effect and the user experience of the large-size display devices are improved. Specifically, for any one of the display devices, according to the method described in steps 201 to 203, when determining that the display device displays the sub-image corresponding to the display device, and after determining the display information of the backlight corresponding to each sampling region in the display device, the image display apparatus sends the sub-image corresponding to the display device and a control instruction including the display information of the determined backlight to the display device, where the control instruction is used to instruct the display device to set the corresponding backlight configured in the frame of the display device according to the color display information of the included backlight.
For example, in the prior art, the display effect of a large-screen display device formed by splicing four display devices is shown in fig. 4a, a gap between two adjacent display devices is clear, and visual experience of a user is affected, after gap compensation is performed by using a backlight configured on a frame of each display device, the display effect of the large-screen display device is shown in fig. 4b, and compared with fig. 4a, the gap between two adjacent display devices has a smaller effect on the image display effect, and the display effect and the user experience of the large-size display device are improved.
In implementation, the image display method provided by the embodiment of the present invention may be applied to each video frame in a sequence of video frames to be displayed in a large-screen display device formed by splicing a plurality of display devices, so as to improve the display effect of the spliced large-size display device, but in this way, when the spliced large-screen display device displays one video frame, the color and/or brightness value of a backlight configured in a frame of each display device needs to be adjusted once, thereby shortening the service life of the backlight. In order to avoid frequent adjustment of the color and/or brightness value of a backlight configured in a frame of a display device and prolong the service life of the backlight, the image display method provided by the embodiment of the invention can be applied to video frames with set time intervals or set frame number intervals in a video frame sequence to be displayed in a large-screen display device formed by splicing a plurality of display devices, and for other video frames in the video, the video frames are directly displayed, and the current color and/or brightness value of the backlight configured in the frame of each display device is kept unchanged.
Specifically, the adjustment period (i.e., the set time interval or the set number of frame intervals) of the color and/or the brightness value of the backlight configured in the frame of the display device may be determined according to the content difference of the adjacent video frames in the video to be displayed. For a video with a small difference in the content of adjacent video frames (a video content changes slowly or still), such as a character close-up video, the adjustment period of the color and/or brightness value of the backlight configured in the frame of the display device is long, while for a video with a large difference in the content of adjacent video frames (a video content changes quickly), such as a video of a sports game, an action movie, and the like, the adjustment period of the color and/or brightness value of the backlight configured in the frame of the display device is short, so that a good display effect is obtained.
In a specific embodiment, before the display device plays a video, a difference of contents of adjacent video frames in the video frame (e.g., a correlation between adjacent video frames) is detected, the video is divided into a plurality of sub-video frame sequences according to a size of the detected difference, and an adjustment period of a backlight when the corresponding sub-video frame sequence is displayed is determined according to a range or an average value of the difference of the contents of the adjacent video frames in each sub-video frame sequence, where an adjustment period of the backlight corresponding to a sub-video frame sequence with a smaller difference of the contents of the adjacent video frames is longer, and an adjustment period of the backlight corresponding to a sub-video frame sequence with a larger difference of the contents of the adjacent video frames is shorter, so as to further improve a display effect of the spliced large-size display device.
