Embodiment Construction

[0016] The purpose of the present invention is to display ultra-high-definition images on ultra-high-definition display screens, figure 1 A specific implementation device of this display method is described, including an input interface 10, a processing unit 20 and an output interface 30, and its specific implementation process can be divided into the following three steps:

[0017] Step 1: The front-end device generates a digital image signal, and the resolution of the digital image can be any resolution, and is input into the processing unit 20 through the input interface 10 .

[0018] Step 2: Since the processing module involves data transfer between three clock regions, the three clock regions include clk_wr, clk_ddr, and clk_rd. Among them, the clock frequency of clk_rd and clk_ddr is fixed, clk_rd is 148.5MHz, which is consistent with the frequency finally output from the system, and clk_ddr is the frequency of operating DDRII memory, which is 100MHz. And clk_wr is the ...

Abstract

The invention relates to a display control method for an ultra high definition screen and a device using the same, which are used for display an image on the ultra high definition screen. The displaycontrol device comprises an input interface used for receiving a digital signal generated by a frontend device and expressing the image, a treatment module used for making the separation treatment ofthe received images, amplifying the separated images respectively and then storing the amplified images in a memory, and an output interface used for reading the image data out of the memory and outputting the images to display on the ultra high definition screen. By the device, the direct drive display of the ultra high definition screen, such as an ultra high definition liquid crystal display screen and an ultra high definition plasma display screen, is realized, and the ultra high definition display of the images is realized. The method and the device fill up a blank in the research on theembedded type ultra high definition screen display drive scheme.

Description

technical field [0001] The invention relates to a display control method and device for a screen, in particular to a display control method and device for an ultra-high-definition screen. Background technique [0002] With the rapid development of screen display technology, the requirements for screen display effects are getting higher and higher. Due to the relatively low resolution of traditional monitoring monitors, some special requirements are not considered in use, so they cannot meet the extremely subtle display requirements at all, so it is necessary to use multiple monitors to form a display wall to achieve this goal. Moreover, in some specific applications, such as airport lobby, railway station platform, telecommunication network management, military combat command, traffic monitoring and other occasions, the demand for high-resolution display screens is also increasing. Therefore, using higher-resolution display screens has become a hot topic, and high-resolutio...
