Embodiment 1

[0049] Refer to attached picture image 3, a device for adjusting an LED display screen on site, including a first control device 201, a collection device 202, and a control device 203;

[0050] In this embodiment, the LED display screen is an LED display screen 102 with a size of 1024*768, and the screen can be divided into 256*192 display units, so the screen is divided into 16 display units, 104a, 104b, . . . , 104p.

[0051] The collection device 202 is used to acquire display characteristic information data required for adjusting the light point of the LED display screen 102 and send it to the first control device 201; the display characteristic information data includes brightness data and picture data. For example, the collection device 202 is a light meter, and the light meter collects brightness data of the light points; the collection device 202 is a camera, and the camera collects picture data of the light points.

[0052] The first control device 201 controls the ...

Embodiment 2

[0056] Refer to attached Figure 4 , on the basis of Embodiment 1, the second control device 301 will transmit, receive and process the information data of the display characteristic information of the collection device 202, such as the image data of the camera and the brightness data of the light meter, and the adjusted The data is sent to the first control device 201 through the Internet network,

[0057] It should be noted that, when the first control device 201 receives the data directly transmitted by the second control device 301, it processes the transmitted data to generate the first adjustment data, and sends it to the sending module in the control device; the first control The device 201 does not process the first adjustment data after receiving the first adjustment data, and sends it directly to the sending module of the control device.

[0058] The second control device 301 may send the first adjustment data or the received data to the first control device 201 by ...

Embodiment 3

[0061] Refer to attached picture figure 2 and image 3 , the present invention also provides a method for adjusting the LED display screen on site, which is carried out according to the following steps:

[0062] A. The first control device controls the LED display to automatically light up some light points on the LED display;

[0063] B. The first control device sends an instruction to the collection device, and the collection device obtains the information data of the display characteristic information of the lighted part of the LED display screen, and sends it to the first control device;

[0064] C. Repeat the above two steps until all the light points of the LED display screen are turned on, and all the information data required are obtained by the collection device and sent to the first control device;

[0065] D. The first control device is used to process all the information data acquired by the acquisition device to obtain first adjustment data, and obtain second a...
