Embodiment Construction

[0128] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation methods, Structure, characteristic and effect thereof are as follows in detail.

[0129] In an embodiment of the present invention, a display device and a video wall having the display device are provided. In the display device of this embodiment, since a data enable signal generator is added, the problem that the synchronous timing signal output by the analog / digital converter does not include the data enable signal can be solved. However, in the framework of the present invention, there is no need for another traditional video amplification chip, such as figure 2 The video amplifying chip 240 shown, therefore, can avoid the video signal received by all subsequent display devices after being processed by the video amplifying chip in the traditional architecture, and the resolution after compression is not t...

Abstract

The invention features a technique that transmits video signal by using differential digital signal to next display unit. The A / D converter in traditional circuit structure can not provide material- enabling signal, and the video amplifying chip providing material-enabling signal has some problem in resolution and time delay. The invention solves the problem above.

Description

technical field [0001] The invention relates to a display device and a video wall with the display device, in particular to a display device for transmitting video signals to the next display device with a differential digital signal and a video wall with the display device. Background technique [0002] In recent years, as the size of individual display devices has reached the development limit, display walls and video walls have been widely used in large-scale exhibition venues and public places to meet the needs of large-scale displays. The video wall is a combination of several display devices, and each display device selects the corresponding part of the display area according to its arranged position to enlarge the maximum screen of the display device. After the combination and arrangement, all the display devices jointly display a complete input video signal. . [0003] Since a video wall combines multiple display devices to display a common video source, computer di...
