Problems solved by technology

It is precisely because the desire for large-screen, multi-color, high-brightness, and high-resolution display effects is becoming stronger and stronger, and traditional TV walls, projection hard splicing screens, and box splicing walls are difficult to meet people's requirements in this regard , so the recent rapid rise of digital edge fusion large-screen projection display technology is gradually becoming an effective way to meet this demand

Embodiment Construction

[0020] 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.

[0021] The window controller provided by the present invention belongs to a part of the large-screen liquid crystal splicing display system. Superimposed on other signals; at the same time, image stretching and roaming can be realized. One signal can be moved and stretched on the entire curtain wall with one screen as a unit; it can be displayed on the whole screen, single screen, and adjacent screens at will. Combination splicing, the screen can be superimposed, window roaming, cross-screen roaming.

[0022] Structurally, such as figure 1 As shown, this kind of windowing controller based on larg...

Abstract

The invention relates to the large screen liquid crystal splicing display field, in particular relates to a windowing controller based on large screen liquid crystal splicing display. In the windowing controller, one or more image windows can be provided on a large screen; image overlapping is realized on the basis of a liquid crystal splicing function, i.e. one signal can be overlapped on other signals and displayed in the whole screen or through a single screen, and adjacent screens can be spliced randomly; and meanwhile, functions such as dragging the window randomly to change the size, screen-crossing roaming, window switching signal and the like can be achieved through control software, and images with super high resolution can be supported.

Description

technical field [0001] The invention relates to the field of large-screen liquid crystal splicing display, in particular to a windowing controller based on large-screen liquid crystal splicing display. Background technique [0002] LCD splicing is a specialized terminal display device designed for engineering applications. Based on the FPGA array, it uses parallel high-speed graphics processing technology to realize the unified processing of multiple high-speed video signals, fundamentally replaces the plug-in splicing controller, and solves the problem of VGA (Video Graphics Array, video image array) signal Issues where the number of entries is limited. It integrates the most outstanding high-definition, high-brightness and high-color gamut liquid crystal display technology, embedded hardware splicing technology, multi-screen image processing technology, signal switching technology, etc., to form a high-brightness, high-definition , low power consumption, long life, advan...
