Embodiment 1

[0027] refer to figure 1 , figure 1 It is an implementation flow chart of the LED display brightness adjustment method provided by the embodiment of the present invention, and is described in detail as follows:

[0028] In step S101, use three-dimensional visualization to build a three-dimensional model of the LED display screen and surrounding buildings;

[0029] Among them, three-dimensional visualization is an existing technology, and the implementation process of constructing a three-dimensional model of the LED display screen and surrounding buildings will not be described here.

[0030] In step S102, real-time dynamic simulation of the sun illumination environment;

[0031] Introduce linear light into the created 3D scene to simulate sunlight, and determine the direction of linear light by calculating the altitude and azimuth angle of the sun. The direction of linear light is the direction of dynamic simulation of sunlight.

[0032] The formulas for calculating the su...

Embodiment 2

[0046] refer to figure 2 , figure 2 It is the implementation flowchart of step S103 of the LED display brightness adjustment method provided by the embodiment of the present invention, and is described in detail as follows:

[0047] In step S201, according to the projection transformation, the projection area of ​​the surrounding buildings on the horizontal plane where the display screen is located is obtained;

[0048] In step S202, the display screen modules located in the sunny area and the shady area are acquired by using the intersection judgment between the projection area and the display screen.

[0049] According to the projection transformation, calculate the projection area of ​​the buildings around the display screen on the horizontal plane where the display screen is located. Using the intersection of the projection area and the display screen, the display screen modules located in the sunny area and the shady area are judged.

[0050] For the sake of illustra...

Embodiment 3

[0058] refer to image 3 , image 3 It is an implementation flowchart of Step S104 of the LED display brightness adjustment method provided by the embodiment of the present invention, and is described in detail as follows:

[0059] In step S301, send a preset sunny brightness value to the display module in the sunny area, and adjust the real-time brightness of the display module in the sunny area to the sunny brightness value;

[0060] Wherein, the first corresponding relationship between the sunny luminance value and the display module in the sunny area is pre-configured, and according to the first corresponding relationship, the preset sunny luminance value is sent to the display module in the sunny area to adjust the The real-time brightness of the display module in the sunny area is the said sunny brightness value.

[0061] In step S302, send a preset shade brightness value to the display screen module in the shade area, and adjust the real-time brightness of the display...

Abstract

The invention is applicable to the technical field of LED display screens, and provides a method and device for adjusting the brightness of LED display screens, and an LED display screen. The method includes: using three-dimensional visualization to construct a three-dimensional model of the LED display screen and surrounding buildings; real-time dynamic simulation Sunlight environment; use projection transformation to obtain the display module located in the sunny area and the display module in the shade area in the three-dimensional model; adjust the real-time brightness of the display module in the sunny area to the preset sunny brightness value, and adjust the real-time brightness of the display module in the shade area to the preset shade brightness value. Under the premise of normal use of the LED display screen, the present invention does not need a built-in brightness sensor array, nor does it need to manually adjust the brightness, thereby not only improving the efficiency of brightness adjustment, but also enabling the method for adjusting the brightness of the LED display screen to be widely used.

Description

technical field [0001] The invention belongs to the technical field of LED display screens, and in particular relates to a method and device for adjusting the brightness of an LED display screen and an LED display screen. Background technique [0002] In recent years, the application of LED display screens in the field of sports has become more and more in-depth and extensive. For example: because LED display screens have more display forms than printed inkjet advertising boards and high utilization efficiency, more and more venues and events use the sidelines The LED peripheral screen is used as the carrier of information dissemination and commercial promotion. In addition, due to the influence of the venue structure and game time where the LED peripheral screen is installed, it is often caused that when the LED peripheral screen is working, part of it is in the bright sunny area, and the other part is in the bright area. Dark shady areas. When the brightness of the entire...
