Embodiment Construction

[0035] In the following, the image display method and system of a plurality of image display devices connected continuously will be described in detail with reference to preferred embodiments and accompanying drawings.

[0036] First of all, in order to facilitate understanding, a plurality of image display instruments in the present invention such as figure 1 The structure is composed of multiple image display devices connected in series, and the image signal input and output terminals are connected by cables.

[0037] That is, the image signal output terminal 100-1g of the first image display device 100-1 is connected with the image signal input end 100-2a of the second image display device 100-2 with a cable, and the second image display device 100-2 is connected with a cable. The image signal output terminal 100-2g of the nth image display device 100-n and the image signal input terminal 100-na of the nth image display device 100-n.

[0038] As mentioned above, it has bee...

Abstract

A method and a system for displaying images in plural display devices are provided to enable a control unit to process the first and second synchronization information and generate horizontal / vertical synchronization timing signals according to the above synchronization information, thereby preventing sync timing delay and displaying normal images. A method for displaying images in plural display devices comprises the following steps of: receiving R,G,B(Red,Green,Blue) signals and the first and second synchronization information in R,G,B input terminals(S100); checking the second synchronization information while obtaining the table value of horizontal / vertical synchronization signals based on the first received synchronization information(S110); intercepting that the table value is generated in an ADC(Analog to Digital Converter) if the second synchronization information is 1 and making the table value generated in the ADC if the second synchronization information is not 1 to convert the R,G,B signal into digital signals(S120~S140); and scaling and displaying the analog-to-digital converted signal(S150,S160).

Description

1. Technical field [0001] The present invention relates to an image display device, specifically an image display method and system for a plurality of image display devices that automatically adjust the synchronous sequence to display normal images when multiple image display devices in series display images. 2. Background technology [0002] Generally, image display devices such as monitors or televisions have an image signal (RGB) output function, and sometimes the same image signal (video cassette recorder, set-top box) is displayed in multiple image display devices connected in series. [0003] figure 1 It is a block diagram of multiple image display instruments connected in series in the prior art. [0004] like figure 1 As shown, a plurality of image display devices connected in series are connected with an image signal output cable, that is, the image signal output terminal of the first image display device is connected with the image signal input end of the second ...
