Embodiment 1

[0029] An example is a system for adjusting the brightness of an LED display screen, including a collection device, an LED display screen, and a first control device connected to the LED display screen; the collection device is used to obtain and adjust the light point of the LED display screen The required first data is sent; wherein, the first data includes brightness data and / or image data; the first control device is used to send the first display data to the LED display screen; it is also used to receive And process the first data, generate adjustment data, and send it to the LED display screen to realize the control of the LED display screen. For example, the acquisition device is a camera, a light meter, or a camera and a light meter.

[0030] For example, the adjustment system further includes a second control device, and the second control device controls the first control device by means of remote control, so as to control the light points on the LED display screen. ...

Embodiment 2

[0036]On the basis of the above examples, an example is an on-site system for adjusting the brightness of an LED display, including a collection device, a first control device, and an LED display; the collection device is used to obtain and adjust the brightness of the LED display The first data required by the screen light point and send it; wherein, the first data includes brightness data and / or image data; the first control device is used to send the first display data to the LED display screen, and is also used to receiving and processing the first data, generating adjustment data, and sending it to the LED display to control the LED display; the LED display is used to receive and display the first display data as The display screen collected by the acquisition device is also used to receive the adjustment data, process the first display data according to the target brightness and the adjustment data, and generate second display data for display.

[0037] For example, the ...

Embodiment 3

[0059] On the basis of the above examples, the adjustment system and / or the field system also includes the second control device, for example, refer to the attached image 3 , the second control device is a second host 301, the second host 301 can transmit, receive and process the image data of the camera 201 and the brightness data of the light meter 202, and send the processed adjustment data to the first host through the Internet 101. The first host 101 sends the first display data and the second adjustment data to the frame controller 102; or, the second host 301 may directly send the data of the peripheral device 201 to the first host without any processing. 101. The first host 101 processes the adjustment data, and then sends the display data and the processed adjustment data to the frame controller 102.

[0060] It should be noted that, when the first host receives the first adjustment data, it processes the first adjustment data through the LED management tool to obtai...

Abstract

The invention relates to a system and method for field regulation of an LED display screen. The system comprises acquisition equipment, first control equipment and the LED display screen; the acquisition equipment is used for acquiring and sending first data required by the regulation of light points of the LED display screen; the first data comprises brightness data and / or image data; the first control equipment is used for sending the first display data to the LED display screen and receiving and processing the first data to generate regulation data to be sent to the LED display screen so as to realize the control the LED display screen; and the LED display screen is used for receiving and displaying the first display data to be used as an acquired display image, also receiving the regulation data, and processing the first display data according to target brightness and the regulation data to generate second display data for displaying. The system and method can be used for realizing the acquisition of the light point brightness of the LED display screen at one time, with accurate data; and in addition, the operation is simple due to full automation, and the effect of the regulated LED light points is obvious and can be presented immediately.

Description

technical field [0001] The invention belongs to the technical field of image display adjustment, and in particular relates to a system structure and an implementation method for on-site adjustment of LED display screens. Background technique [0002] The LED display screen is composed of hundreds of thousands or even millions of semiconductor light-emitting diodes, namely: LED light points. Various factors such as different optical properties of the light points, component aging, drive error, inconsistency in the angle of the light point itself, dust on the light point, and shielding of the hat brim to protect the light point will cause uneven brightness of the light point on the screen. At present, the main ways to solve this uneven phenomenon: one is to improve the consistency of the optical characteristics of LED lights, and the other is to improve the uniformity of the display screen by means of correction. The consistent way to improve the optical characteristics of LE...
