Abstract

The invention discloses an LED display control system, and the system comprises a driving power supply. The invention belongs to the technical field of dome screen display, and the system is characterized in that the system further comprises a visual computer, a video image processor, an optical transceiver, a video transmitter, a video receiving card and a controller which are electrically connected; the visual computer is used for synchronously outputting video images of a plurality of channel applications; the video image processor is used for realizing pixel-level geometric correction andimage clipping of the application video image; the video transmitter is used for performing interface conversion on the digital video signal; the video receiving card receives the video data sent by the video sender; the controller carries out overvoltage, overcurrent and over-temperature detection on power supply of the LED display screen by controlling the power-on time sequence of the LED display screen. The display pixels are uniformly distributed, and secondary correction of brightness and color is not needed; image fusion at the edge and consistency correction of brightness and color arenot needed, the image processing steps are simpler and more convenient, and the maintenance cost is low.

Description

technical field

[0001] The invention relates to the technical field of ball screen display, in particular to an LED display control system. Background technique

[0002] Immersive dome displays all use projection display technology. Multiple projectors use image splicing and fusion to realize the dome display function. On the one hand, it is difficult to achieve full-field display in this way, especially in real image display systems. Because once an observer or object is inside the system, it will block part of the display area; on the other hand, in addition to image geometric correction, this display method also needs image stitching and image fusion. Due to the large stitching and fusion area, The actual pixel utilization per projector is very small.

[0003] At present, the applications in the LED spherical field mainly include LED outer spherical display, LED dome display and LED hemispherical display, and these applications are mainly concentrated in commercial adver...
