Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The light emitting method provided by the application can be applied to a terminal, can also be applied to a server, can also be applied to a system comprising the terminal and the server, and is realized through the interaction of the terminal and the server. The terminal can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices, and the server can be implemented by an independent server or a server cluster formed by a plurality of servers.

The terminal and/or the server may control a Liquid Crystal Display (LCD) shown in fig. 1 to implement the above-described light emitting method. As shown in fig. 1a, the LCD includes an LCD panel, an upper diffusion sheet, an upper brightness enhancement sheet, a lower diffusion sheet, a light guide layer, and a light emitting surface. The light emitting surface is used for providing a light source to realize the display of images. As shown in fig. 1b, a plurality of light emitting sources capable of emitting light are disposed on the light emitting surface.

In one embodiment, as shown in fig. 2, a method for emitting light is provided, which is described by taking the method as an example for a terminal, and includes the following steps:

step 202, performing area division on the light emitting surface to obtain a plurality of areas to be arranged.

The light-emitting surface is one of the important components of the LCD backlight module, and because the light-emitting surface is configured with a plurality of light-emitting sources, the light-emitting surface is used to provide sufficient light sources. The area to be arranged is an area obtained by dividing the light emitting surface into areas, and the light emitting surface can be obtained by combining a plurality of areas to be arranged.

Specifically, the terminal can obtain the light emitting surface by scanning or establishing a virtual model, so that the light emitting surface is controlled, and the light emitting method is realized. The terminal can divide the area of the luminous surface to obtain a plurality of areas to be arranged with the same size. Alternatively, a region to be arranged is obtained in the light-emitting surface in an integer proportional relationship with the size of the light-emitting surface, in accordance with the size of the light-emitting surface.

In one embodiment, the light emitting surface may be a conventional panel that has been configured with light emitting sources. Wherein the light emitting sources on the light emitting surface are regularly and equidistantly arranged as shown in fig. 1 b.

In one embodiment, the light emitting surface may be a panel without light emitting sources, and similarly, the region to be arranged may also be a region where light emitting sources are arranged. When the light emitting surface is not configured with the light emitting source, the terminal can configure the light emitting source for one to-be-arranged area of the light emitting surface according to the traditional mode, the arrangement mode of the light emitting source in the to-be-arranged area is adjusted through the light emitting method, and then the light emitting source is configured for the light emitting surface according to the arrangement mode of the adjusted light emitting source in the to-be-arranged area.

Step 204, obtaining a current region to be arranged from the plurality of regions to be arranged, and randomly adding a plurality of light emitting sources into the current region to be arranged.

Wherein the region to be arranged is any one region in the luminous surface. The size of the current region to be arranged is in integral proportion to the size of the light-emitting surface.

Specifically, the terminal selects one area from a plurality of areas to be arranged obtained by dividing the light emitting surface as the current area to be arranged. Or, the terminal arbitrarily extracts an area in integral proportion to the size of the light emitting surface from the light emitting surface as the current area to be arranged.

Further, when the current region to be arranged is configured with the light emitting sources at equal intervals in a conventional manner, the terminal randomly adds a plurality of light emitting sources in the current region to be arranged. Wherein the positions and the number of the newly added luminous sources are random.

And step 206, acquiring a target distance range and initial positions of all the light-emitting sources in the current region to be arrayed.

The target distance may be the distance between the light emitting sources equidistantly arranged in the current region to be arranged; other values are possible for specifying the spacing between the individual light-emitting sources in the area currently to be arranged. The target pitch range is a range set in combination with a margin of allowable error on the basis of the target pitch. For example, if the target pitch is 4mm (millimeters), then the target pitch may range from 3.5mm (millimeters) to 4.5mm (millimeters). Each luminous source in the current region to be arranged comprises luminous sources which are equidistantly arranged and new luminous sources which are randomly added. The initial position is an initial configuration position before the arrangement mode of each luminous source in the current area to be arranged is not adjusted.

And 208, adjusting the initial positions of all the luminous sources in the current region to be arranged according to the target distance range and the triangulation method to obtain the target positions of all the luminous sources in the current region to be arranged.

The target position is a configuration position planned by the terminal for each luminous source in the current region to be arranged. The target position may be the same as the initial position or may be different from the initial position.

Specifically, since the new light sources are added randomly, the brightness uniformity of the current region to be arranged cannot be guaranteed, and therefore, the initial positions of the light sources in the current region to be arranged need to be adjusted. And the terminal adjusts the initial positions of all luminous sources in the current region to be arranged by a target distance range and a triangulation method. The triangulation method is a basic research method of algebraic topology. When a plane is divided into a block of fragments by a triangulation method, the following conditions are required to be satisfied: (1) each fragment is triangular; (2) Any two triangles on the plane can only have one common side at most. Due to the characteristics of the triangulation method, each luminous source in the current area to be arranged is used as a vertex, so that the current area to be arranged is divided into a plurality of approximately equilateral triangles, namely, the distances among the luminous sources are approximately equal. The target distance range is used for restricting the distance between the light-emitting sources, that is, after the triangulation method and the target distance range are adjusted, the distances between the light-emitting sources in the current region to be arranged are approximately equal and basically belong to the target distance range, and the adjusted positions are used as the target positions of the light-emitting sources in the current region to be arranged.

In one embodiment, in the process of adjusting the initial positions of the light-emitting sources in the current region to be arranged, if the adjusted distance between the light-emitting sources exceeds the target distance range, the number of the light-emitting sources added at random needs to be adjusted. When the adjusted distance between the light-emitting sources is smaller than the lower limit value of the target distance range, the number of the light-emitting sources added randomly can be reduced, and then the distance between the light-emitting sources in the current region to be arranged is further adjusted through a triangulation method and the target distance range, so that the target position of each light-emitting source in the current region to be arranged is obtained. When the adjusted distance between the light-emitting sources is larger than the upper limit value of the target distance range, the number of the light-emitting sources added randomly can be increased, and then the distance between the light-emitting sources in the current region to be arranged is further adjusted through a triangulation method and the target distance range, so that the target position of each light-emitting source in the current region to be arranged is obtained.

Step 210, arranging each luminous source in the current region to be arranged according to the target position to obtain the target arrangement mode of the luminous source in the current region to be arranged.

The target arrangement mode comprises the number of the luminous sources and target positions corresponding to the luminous sources.

Step 212, arranging the light sources of other areas to be arranged in the light emitting surface according to the target arrangement mode of the light sources in the current area to be arranged to obtain the arranged light emitting surface.

Specifically, the terminal can copy the target arrangement mode of the light emitting sources in the current area to be arranged to other areas to be arranged in the light emitting surface, so that the arrangement modes of the light emitting sources in the other areas to be arranged in the light emitting surface are the same as those of the light emitting sources in the current area to be arranged, and are all the target arrangement modes, the brightness uniformity of each area in the light emitting surface can be ensured, and the arranged light emitting surface is obtained by combining a plurality of arranged areas to be arranged.

In one embodiment, when the current region to be arranged is a region extracted from the light emitting surface and proportional to the size of the light emitting surface, the arranged current region to be arranged may be tiled according to an integer proportional relationship, so as to obtain the arranged light emitting surface.

In one embodiment, after triangulation is performed on the current region to be arranged, the light emitting sources at the outermost periphery may be regularly arranged, so that the light emitting sources at the outermost periphery and regularly arranged in the current region to be arranged may be removed first, and then the target arrangement manner of the light emitting sources in the current region to be arranged is copied to other regions to be arranged in the light emitting surface, so as to obtain the arranged light emitting surface.

In one embodiment, after the target arrangement manner of the light emitting sources in the current region to be arranged is copied to other regions to be arranged in the light emitting surface, there may be a case where the distance between the light emitting sources in the adjacent regions at the region boundary exceeds the target distance range, that is, is greater than the upper limit value of the target distance range or is less than the lower limit value of the target distance range. Therefore, after the target arrangement mode of the luminous sources in the current area to be arranged is copied to other areas to be arranged in the luminous surface, the distance between the areas to be arranged can be finely adjusted, so that the distance between the luminous sources at the area boundary basically falls into the target distance range, and the brightness uniformity is ensured.

And 214, controlling the arranged light-emitting surfaces to emit light.

In the light emitting method, a plurality of regions to be arranged are obtained by dividing the light emitting surface into regions; acquiring a current region to be arranged, and randomly adding a plurality of luminous sources into the current region to be arranged; acquiring a target distance range and initial positions of all luminous sources in a current region to be arrayed; adjusting the initial position of each luminous source in the current region to be arranged according to the target distance range to obtain the target position of each luminous source in the current region to be arranged; the light-emitting sources in the current region to be arranged are arranged according to the target positions, the target arrangement mode of the light-emitting sources in the current region to be arranged is obtained, the brightness uniformity of the current region to be arranged can be guaranteed, meanwhile, the interference phenomenon is avoided, and the display effect is improved. And arranging the luminous sources of other areas to be arranged in the luminous surface according to the target arrangement mode of the luminous sources in the current areas to be arranged to obtain the arranged luminous surface, and controlling the arranged luminous surface to emit light, so that the calculation amount can be reduced, the arrangement efficiency of the luminous sources in the luminous surface is improved, the brightness uniformity of each area to be arranged in the luminous surface is ensured, the interference phenomenon is avoided, and the display effect of the luminous surface is improved.

In one embodiment, as shown in FIG. 3, step 208 includes:

step 302, connecting each luminous source in the current region to be arranged based on a triangulation method according to the initial position of each luminous source in the current region to be arranged to obtain a connecting line set, and calculating the length of each connecting line in the connecting line set;

step 304, acquiring a correction coefficient, and calculating to obtain a movement vector of each light emitting source in the current region to be arranged according to the length of each connecting line, the target distance range and the correction coefficient;

step 306, adding the initial positions of the light-emitting sources in the current region to be arranged and the corresponding motion vectors to obtain the target positions of the light-emitting sources in the current region to be arranged.

The most common triangulation method is the Delaunay triangulation method, which requires the sum of the side lengths of triangles to be the minimum as possible, and the circumscribed circle of each triangle does not contain any other point in the plane. Wherein, the Delaunay triangulation method comprises the following steps: a flanging algorithm, a point-by-point insertion algorithm, a segmentation and combination algorithm, a Bowyer-Watson algorithm and the like. The terminal can adjust the initial positions of the light emitting sources in the current region to be arranged by any triangulation method, which is not limited herein.

Specifically, each light emitting source in the current region to be arranged is taken as a vertex, and the terminal connects each light emitting source with its adjacent light emitting source satisfying the triangulation method based on the triangulation method according to the initial position of each light emitting source in the current region to be arranged, so as to obtain a connection line set. And then, the length of each connecting line in the connecting line set, namely the distance between two connected luminous sources can be calculated through the initial position of each luminous source in the current region to be arranged.

Further, after the length of each connecting line, that is, the distance between two connected light-emitting sources is obtained, the position of each light-emitting source needs to be adjusted, so that the distance between the two connected light-emitting sources can be within a target distance range, and the uniformity of the luminance of light emission is ensured. When the initial positions of the light emitting sources in the current region to be arranged are adjusted, the terminal can obtain preset correction coefficients, and the movement vectors of the light emitting sources in the current region to be arranged are obtained through the length of each connecting line, the target distance range and the correction coefficients. Wherein the movement vector comprises a movement distance and a movement direction.

Step 306 includes: acquiring a correction coefficient, and calculating the moving distance of each luminous source in the current region to be arranged according to the length of each connecting line and the correction coefficient; determining the moving direction of each luminous source in the current region to be arranged according to the length of each connecting line and the target distance range; and the initial moving distance and the initial moving direction form the moving vector of each luminous source in the current region to be arranged.

Wherein the correction coefficient is a proportionality coefficient for correcting a deviation between a pitch between the connected light emitting sources and a target pitch range.

Specifically, the terminal multiplies the length of the current connection line by the correction coefficient, so as to obtain the moving distance of the light emitting source corresponding to the current connection line. And judging the relationship between the length of the current connecting line and the target distance range, and when the length of the current connecting line is greater than the upper limit value of the target distance range, taking the direction of shortening the connecting line as the moving direction of the luminous source corresponding to the current connecting line. And when the length of the current connecting line is smaller than the lower limit value of the target distance range, taking the direction of stretching the connecting line as the moving direction of the luminous source corresponding to the current connecting line.

Step 308 comprises: when the moving distance of each luminous source in the current area to be arranged is larger than a preset moving distance threshold value, adding the initial position of each luminous source in the current area to be arranged and the corresponding moving vector to obtain the target position of each luminous source in the current area to be arranged; and when the moving distance of each luminous source in the current region to be arranged is smaller than a preset moving distance threshold value, taking the initial position of each luminous source in the current region to be arranged as a target position.

The preset moving distance threshold is used for limiting the moving times of each luminous source in the current region to be arranged, so that repeated and invalid movement of each luminous source in the current region to be arranged is avoided, and the efficiency can be improved while the luminous sources are effectively moved.

Specifically, when the moving distance of each light emitting source in the current region to be arranged is greater than a preset moving distance threshold, the moving distance is added to the initial position of each light emitting source in the current region to be arranged in the moving direction, so as to obtain the target position of each light emitting source in the current region to be arranged. After each luminous source in the current region to be arranged is moved to the corresponding target position, the target position is used as an initial position, the operation of calculating the movement vector of each luminous source in the current region to be arranged and moving each luminous source in the current region to be arranged from the initial position to the corresponding target position is repeatedly executed. And when the moving distance of each luminous source in the current region to be arranged is smaller than a preset moving distance threshold value, directly taking the initial position of each luminous source in the current region to be arranged as a target position, and stopping further moving each luminous source. The finally obtained adjusted connection line set in the current region to be arranged is shown in fig. 4. As shown in fig. 4, different from the conventional regular equidistant arrangement, the adjusted light-emitting sources in the current area to be arranged are irregularly and approximately equidistantly arranged, so that the interference phenomenon can be avoided while the brightness uniformity is ensured, and the display effect is improved.

In this embodiment, the initial positions of the light sources in the current region to be arranged are adjusted through a triangulation method and a target distance range to obtain the target positions of the light sources in the current region to be arranged, and under the combined action of the triangulation method and the target distance range, the adjusted light sources in the current region to be arranged are irregularly and approximately equidistantly arranged, so that the interference phenomenon can be avoided while the brightness uniformity is ensured, and the display effect is improved.

In one embodiment, as shown in FIG. 5, step 212 includes:

502, arranging the luminous sources in other areas to be arranged in the luminous surface according to the target arrangement mode of the luminous sources in the current areas to be arranged to obtain a plurality of target arrangement areas;

step 504, acquiring the position of the boundary light-emitting source of each target arrangement region, and calculating the distance of the boundary light-emitting source corresponding to the adjacent target arrangement region according to the position of the boundary light-emitting source of each target arrangement region;

step 506, determining the region spacing between each target arrangement region according to the distance of the boundary luminous source corresponding to the adjacent target arrangement regions;

and step 508, combining the target arrangement regions according to the region spacing among the target arrangement regions to obtain the arranged light emitting surface.

The target arrangement region is a region obtained by arranging the light-emitting sources in the region to be arranged according to a target arrangement mode. The boundary light-emitting sources are light-emitting sources located at the boundaries of the respective target arrangement regions.

Specifically, the terminal arranges the light emitting sources in other to-be-arranged areas in the light emitting surface according to the target arrangement mode of the light emitting sources in the current to-be-arranged area, so that a plurality of target arrangement areas can be obtained. And acquiring the positions of the boundary luminous sources of the target arrangement regions, and connecting the boundary luminous sources of the target arrangement regions based on a triangulation method according to the positions of the boundary luminous sources of the target arrangement regions to obtain a plurality of boundary connecting lines. And calculating the length of each boundary connecting line, namely the distance of the boundary luminous sources corresponding to the adjacent target arrangement regions according to the positions of the boundary luminous sources of each target arrangement region. And comparing the distance of the boundary luminous sources corresponding to the adjacent target arrangement regions with the target distance range, and determining the region distance between the target arrangement regions according to the comparison result.

Step 506 specifically includes: when the distance of the boundary luminous sources corresponding to the adjacent target arrangement areas exceeds the target distance range, moving each target arrangement area, and adjusting the distance of the boundary luminous sources corresponding to the adjacent target arrangement areas to be within the target distance range; and acquiring the position of each target arrangement region after the movement, and calculating to obtain the region spacing between each target arrangement region according to the position of each target arrangement region after the movement.

In one embodiment, the adjacent target arrangement region includes a plurality of boundary light sources, and the terminal may calculate lengths of boundary connection lines corresponding to the current adjacent target arrangement region, compare the lengths of the boundary connection lines corresponding to the current adjacent target arrangement region with the target distance range, and determine a motion vector of each boundary light source. The terminal superposes the motion vectors of all boundary luminous sources corresponding to the current adjacent target arrangement regions to obtain the motion vectors of the current adjacent target arrangement regions, so that the region spacing between the current adjacent target arrangement regions is determined.

In one embodiment, the terminal may slightly move each target arrangement region in each direction, such as up, down, left, right, and the like, to achieve fine adjustment of the region interval between each target arrangement region, thereby determining the region interval between each target arrangement region, so that the distribution of the boundary light-emitting sources in each target arrangement region is consistent with the distribution of the light-emitting sources at the center position of each target arrangement region, and ensuring brightness uniformity.

Further, after determining the inter-region distances between the respective target arrangement regions, the terminal combines the respective target arrangement regions according to the inter-region distances between the respective target arrangement regions, and may obtain the arranged light emitting surface, as shown in fig. 6. In fig. 6, the large area on the right side is the entire arrayed light-emitting surface, and the small area on the left side is one of the target arrayed areas.

In the embodiment, the light sources of other regions to be arranged in the light emitting surface are arranged by the target arrangement mode of the light sources in the current region to be arranged, so that a plurality of target arrangement regions can be quickly obtained, and the arranged light emitting surface can be quickly obtained; and the interval of each luminous source in the whole arranged luminous surface is kept consistent basically by adjusting the interval of the areas among the target arrangement areas, so that the brightness uniformity is ensured.

In one embodiment, as shown in fig. 7, another light emitting method is provided, which is described by taking the method as an example for being applied to a terminal, and includes the following steps:

step 702, performing area division on a light-emitting surface to obtain a plurality of areas to be arranged with the same size;
