The method for adjusting the spliced bright and dark lines provided by the embodiment is applied to the spliced LED display screen adjusting system shown in fig. 5, and for convenience of understanding the embodiment more clearly, the method for adjusting the spliced bright and dark lines of the embodiment is described in detail below with reference to fig. 5 and fig. 6A to 6D.
Referring to fig. 5, the tiled LED display screen adjustment system can include, for example, a client 100, an LED display control system 200, and a tiled LED display 300. The client 100 is connected with the LED display control device 200, and the LED display control device 200 is connected with the spliced LED display screen 300. Wherein, concatenation formula LED display screen 300 includes a plurality of concatenation units that splice together, and LED display control device 200 is used for controlling concatenation formula LED display screen 300.
Specifically, the client 100 may be, for example, a personal computer, on which splicing bright and dark line adjustment software is installed, and a user may, for example, open the splicing bright and dark line adjustment software, and first, for example, the LED display control device 200 may control the spliced LED display screen 300 to display, for example, a white picture suitable for bright and dark line adjustment, so as to facilitate the user to observe the splicing bright and dark lines on the spliced LED display screen 300, and of course, other pictures may also be used, which is not limited in this embodiment. Referring to fig. 6A, the splicing bright and dark line adjusting software may, for example, acquire position information and resolution information of a plurality of splicing units of the spliced LED display screen 300 through the LED display control device 200, draw a distribution schematic diagram of the plurality of splicing units in a software interface according to the position information and resolution information of the plurality of splicing units (as shown in fig. 6A, only 4 splicing units are shown as a schematic diagram), and display a boundary of the plurality of splicing units in the distribution schematic diagram.
As mentioned above, referring to fig. 6B, a user may select a boundary needing to be adjusted, i.e. a target adjustment boundary in the tiled LED display screen, for example, in the distribution diagram shown in fig. 6A by using a mouse, for example, the user selects the target adjustment boundaries 101 and 102 in fig. 6B, and the software may acquire position information of the target adjustment boundary in the tiled LED display screen 300, for example, in response to the selection operation of the user, which may include, for example, a start coordinate, a width and a height of the target adjustment boundary, but the embodiment of the present invention is not limited thereto.
Because the restriction of processing reasons such as machining, assembly precision, can produce the concatenation gap in concatenation unit and concatenation unit's concatenation department at concatenation formula LED display screen 300's concatenation build the in-process, specifically can for example as shown in FIG. 6C, the wedge limit seam is apart from the difference promptly about the concatenation limit seam, bright dark line can appear when showing, and such bright dark line also is called the bright dark line of wedge concatenation.
Specifically, when the wedge-shaped bright and dark lines need to be adjusted, that is, the user selects the lamp points 303 and 304 of the target adjustment boundaries 101 and 102 in fig. 6B corresponding to the splicing edges on the spliced display screen 300 (see fig. 6C), the splicing bright and dark line adjustment software on the client 100 obtains the position information of the target adjustment boundaries in response to the operation of the user selecting the target adjustment boundaries; the user may, for example, select a lamp point on the target adjustment boundary 101 as a reference lamp point, and then input the brightness adjustment data of the reference lamp point by drag adjustment or direct input, and the client 100 acquires the reference lamp point position information and the reference lamp point brightness adjustment data in response to the user operation. The client 100 sends the brightness adjustment instruction including the position information of the target adjustment boundary, the reference lamp point position information, and the reference lamp point brightness adjustment data in the tiled LED display screen 300 to the LED display control device 200.
As described above, the LED display control device 200 receives the brightness adjustment instruction, and adjusts the brightness of the target adjustment boundary according to the position information of the target adjustment boundary, the reference lamp point position information, and the reference lamp point brightness adjustment data.
Specifically, when the reference lamp points are two, the reference lamp points that can be specified by the user are, for example, the first lamp point and the last lamp point on the target adjustment boundary, that is, the reference lamp point position information acquired by the client 100 includes first reference lamp point position information (position information of the first lamp point) and second reference lamp point position information (position information of the last lamp point), and the reference lamp point brightness adjustment data includes a first reference lamp point brightness adjustment coefficient (brightness adjustment coefficient of the first lamp point) and a second reference lamp point brightness adjustment coefficient (brightness adjustment coefficient of the last lamp point). The LED display control device 200 determines a target LED lamp point to be adjusted according to the position information of the target adjustment boundary, the position informationThe information may include, for example, a start coordinate, a width, and a height, from which the LED display control device 200 determines a target adjustment boundary on the tiled LED display screen 300 that needs to be adjusted. Then, a target brightness adjustment coefficient of the target LED lamp point is calculated based on the first reference lamp point position information, the second reference lamp point position information, the first reference lamp point brightness adjustment coefficient, and the second reference lamp point brightness adjustment coefficient, specifically, the LED display control device 200 may, for example, acquire the number of LED lamp points of the target adjustment boundary may, for example, be 6, determine that the first reference lamp point is the first lamp point based on the first reference lamp point position information, determine that the second reference lamp point is the last lamp point based on the second reference lamp point position information, then calculate a difference value between the first reference lamp point brightness adjustment coefficient may, for example, be 1 and the second reference lamp point brightness adjustment coefficient may, for example, be 2, may, for example, be 1, and then calculate a difference value between the first reference lamp point brightness adjustment coefficient and the second reference lamp point brightness adjustment coefficient may, for example, be 2, based on the first reference lamp point position information, the second reference lamp point brightness adjustment coefficient, and the second reference lamp point brightness adjustment coefficient
Figure GDA0003862933940000131
The brightness adjustment coefficient of each target adjustment lamp point in the target adjustment boundary is obtained, and specifically, for example, the brightness adjustment coefficient of the second LED lamp point is 1.2, the brightness adjustment coefficient of the third LED lamp point is 1.4, the brightness adjustment coefficient of the fourth LED lamp point is 1.6, and the brightness adjustment coefficient of the fifth LED lamp point is 1.8, which is only illustrated here by way of example, and the target brightness adjustment coefficient of the target LED lamp point may also be obtained by other calculation methods, which is not limited in this embodiment of the present invention. After obtaining a target brightness adjustment coefficient 1.2 for a target LED lamp point, for example, a second lamp point, the LED display control device 200 adjusts the brightness of the second LED lamp point according to the target brightness adjustment coefficient 1.2.

The method for adjusting the spliced bright and dark lines provided by this embodiment is applied to the spliced LED display screen adjustment system shown in fig. 5, and for facilitating understanding of this embodiment more clearly, the method for adjusting the spliced bright and dark lines of this embodiment is described in detail below with reference to fig. 5, fig. 6A, fig. 6B, and fig. 11.
Referring to fig. 5, the tiled LED display screen adjustment system can include, for example, a client 100, an LED display control system 200, and a tiled LED display 300. The client 100 is connected with the LED display control device 200, and the LED display control device 200 is connected with the spliced LED display screen 300. Wherein, concatenation formula LED display screen 300 includes a plurality of concatenation units that splice together, and LED display control device 200 is used for controlling concatenation formula LED display screen 300.
Specifically, the client 100 may be, for example, a personal computer, on which splicing bright and dark line adjustment software is installed, and a user may, for example, open the splicing bright and dark line adjustment software, and first, for example, the LED display control device 200 may control the spliced LED display screen 300 to display, for example, a white picture suitable for bright and dark line adjustment, so as to facilitate the user to observe the splicing bright and dark lines on the spliced LED display screen 300, and of course, other pictures may also be used, which is not limited in this embodiment. Referring to fig. 6A, the splicing bright and dark line adjusting software may, for example, acquire position information and resolution information of a plurality of splicing units of the spliced LED display screen 300 through the LED display control device 200, draw a distribution diagram of the plurality of splicing units in a software interface according to the position information and resolution information of the plurality of splicing units (as shown in fig. 6A, only 4 splicing units are shown as an illustration), and display boundaries of the plurality of splicing units in the distribution diagram.
As mentioned above, referring to fig. 6B, a user may select a boundary needing to be adjusted, i.e. a target adjustment boundary in the tiled LED display screen, for example, in the distribution diagram shown in fig. 6A by using a mouse, for example, the user selects the target adjustment boundaries 101 and 102 in fig. 6B, and the software may acquire position information of the target adjustment boundary in the tiled LED display screen 300, for example, in response to the selection operation of the user, which may include, for example, a start coordinate, a width and a height of the target adjustment boundary, but the embodiment of the present invention is not limited thereto.
Due to the limitation of technological reasons such as machining and assembling precision, the splicing gap generated at the splicing position of the splicing unit and the splicing unit can be, for example, a conventional side seam with the same vertical distance as the side seam shown in fig. 11, bright and dark lines can appear during display, and the bright and dark lines are also called as conventional splicing bright and dark lines.
Specifically, when the bright and dark lines to be adjusted are the conventional spliced bright and dark lines (i.e., the splicing state of the spliced LED display screen 300 is shown in fig. 11), the user selects the lamp points 301 and 302 of the target adjustment boundaries 101 and 102 in fig. 6B corresponding to the splicing edges on the spliced LED display screen 300 (see fig. 11). The brightness adjustment coefficient change data of the selected target adjustment boundary may be specifically, for example, a brightness adjustment coefficient change value, and the brightness adjustment coefficient change value may be, for example, an increase or decrease amount of the brightness adjustment coefficient, that is, the brightness adjustment coefficient change value is a positive number or a negative number. Taking the target adjustment boundary to be adjusted as the splicing edge light point 301 in fig. 11 as an example, the user may need to dim the light point of the target adjustment boundary by some amount, for example, the input brightness adjustment coefficient change value is-0.2, and the software may obtain the brightness adjustment coefficient change value of-0.2 in response to the user input, for example.
In this way, the software sends a brightness adjustment instruction including the position information of the target adjustment boundary and the brightness adjustment coefficient change value to the LED display control device 200, the LED display control device 200 receives the brightness adjustment instruction, and determines a target LED lamp point to be adjusted according to the position information of the target adjustment boundary; acquiring a current brightness adjusting coefficient of the target LED lamp point, wherein the current brightness adjusting coefficient is 1 for example; adding the current brightness adjusting coefficient 1 and the brightness adjusting coefficient variation value-0.2 to obtain a target brightness adjusting coefficient 0.8; and then, adjusting the brightness of the target LED lamp point according to the target adjustment system 0.8, specifically, for example, multiplying the brightness value of the target lamp point, for example, 255, by the target adjustment coefficient 0.8 to obtain a new target lamp brightness value, so as to adjust the brightness of the target LED lamp point. When the target LED light point needs to be adjusted twice, for example, the brightness of the target LED light point needs to be increased a little, the brightness adjustment coefficient change value input by the user, which can be obtained by software, is 0.1; the LED display control device 200 obtains that the current brightness adjustment coefficient is 0.8, adds the current brightness adjustment coefficient 0.8 and the brightness adjustment coefficient variation value 0.1 to obtain a target brightness adjustment coefficient 0.9, and then performs brightness adjustment on the target LED lamp point according to the target brightness adjustment coefficient 0.9, that is, completes the secondary brightness adjustment on the target LED lamp point. Therefore, the user only needs to select the target adjusting boundary and adjust the brightness adjusting coefficient change value to realize the brightness adjustment of the target adjusting boundary, namely finish the brightness and dark line adjustment, the user operation is simplified, and the user experience is improved.
In summary, in the spliced bright and dark line adjusting method of the embodiment, the position information of the target adjusting boundary and the brightness adjusting coefficient change data of the target adjusting boundary in the spliced LED display screen are acquired, and the brightness adjusting instruction including the position information of the target adjusting boundary and the brightness adjusting coefficient change data is sent to the LED display control device, so that the LED display control device adjusts the brightness of the target adjusting boundary according to the current brightness adjusting coefficient of the target adjusting boundary and the brightness adjusting instruction.
