Abstract

The invention provides a method and an apparatus for achieving the display of patched high definition base image by using a U disk or / and a flash memory. According to the method, an image decoding module receives external input signals which are output to an image zooming module after being decoded. Then the decoded signals are transmitted to an image overlaying module to be overlaid with image signals read by a U disk controller or a flash memory controller. The overlaid images are output as video signals by an image output module, wherein the physical resolution of the video signals is the same with that of the display. The apparatus comprises the image decoding module, the image zooming module, the U disk controller or the flash memory controller, the image overlaying module and the image output module. A mainboard control unit is connected with a microcontroller through a control bus interface. By adopting the U disk controller or the flash memory controller, the apparatus resolves the display problem of high-definition base images, thereby achieving perfect patching for the high-definition base images.

Description

technical field [0001] The invention relates to a large-screen splicing controller to realize a high-definition base map technology. The resolution of the base image is required to correspond to the physical display resolution of the large-screen splicing device, so that the point-to-point display is much higher than that of photos, pictures or images of a single display unit. Other signals mainly refer to a method for realizing splicing high-definition base image display based on U disk or flash memory and a display device thereof. Background technique [0002] At present, the methods for realizing the base image are as follows: 1. Input the base image signal through the VGA interface, and then use the amplification function of the splicing controller to amplify the base image signal transmitted through the VGA to the splicing wall. This method can be implemented very simply. The base image is displayed, but the resolution of the base image is displayed by the transmission ...
