Problems solved by technology

[0045] In order to solve the problems existing in the prior art, the present invention provides a LED screen multi-mode display method, without changing the resolution of the video source, so that the video source can be played on an LED screen with a larger resolution than the video source, Reduce the requirements for video source resolution, thereby reducing the difficulty of material production, and can also effectively reduce the investment in front-end equipment such as video processors, screen system receiving cards, etc., and solve the existing needs of existing technologies to use different resolutions according to different application scenarios LED screens and the system complexity brought about by the replacement of large-pitch screens with small-pitch screens, the doubling of front-end system equipment, and the sharp increase in the cost of video material production

Embodiment Construction

[0062] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0063] Large-scale LED or even super-large LED screens are spliced ​​by single LED cabinets. The spliced ​​LED screen has a main controller (sending card), and each LED cabinet has a sub-controller (receiving card).

[0064] combine image 3 , 5 7. In the case of a single-screen single-mode display, the resolution of the video source is the same as that of the LED display, and one pixel corresponds to one LED bead of the LED screen. For example, the resolutions of the LED display screen and the video source are both 1920*1080. The video source player device outputs video signals to the main contr...

Abstract

The invention provides an LED screen one-screen-multiple-mode display method. The method includes: acquiring resolution a signal source and an LED screen; according to the resolution of the signal source and the LED screen, acquiring multiple N between the two, wherein N is an integer; taking pixel points of the signal source as N-way signals to be output, and displaying at N display positions corresponding to the LED screen. By the method, one pixel point can correspond to multiple screen LED display lamp points, light emitting area of each LED display lamp point is increased, pictures are softer, and mosaic and moire phenomena of a high-density display screen under a camera lens can be avoided effectively. Investment on front-end equipment like a video processor and a screen system sending card is effectively reduced, and video material making difficulty is lowered.

Description

technical field [0001] The invention belongs to the technical field of LED display, and in particular relates to a LED screen-one-screen multi-mode display method and system. Background technique [0002] LED display has become a widely used carrier for information release and dissemination, and it is increasingly developing in the direction of high density and small spacing. [0003] With the help of front-end equipment such as video source, sending card, and receiving card, the LED display converts and transmits the signal to the LED lamp bead and displays the playback information through the LED lamp bead (light-emitting diode). One LED lamp bead is one pixel point, small spacing, High-density products, that is, the number of LED lamp beads per unit area has increased significantly, and the number of pixels has also increased simultaneously. At the same time, the front-end equipment of the LED display screen will inevitably increase continuously, and the equipment cost, ...
