Description

DETACHABLE DVI CONNECTION MODULE < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection module between a video display device and a video providing device, and more particularly, to a DVI connection module between a DVI transmitting device and a DVI receiving device.

Recently, various multimedia devices that reproduce and transmit various multimedia contents have developed along with the diversification of multimedia contents, and a simple and lossless interface technology for signal connection between them has been developed.

The most popular multimedia interface is DVI. DVI (Digital Visual Interface) is a digital visual interface (DVI) developed by a consortium of major companies in the computer industry called Digital Display Working Group to digitally connect video displays such as monitors and video output devices such as PCs. Transmission specification.

Since the introduction of LCD (liquid crystal) type monitors began to take off in the late 1990s, the limitations of the analog video interface have become more evident. Since the LCD processes digital image data, digital signals transmitted from the computer are displayed without degradation can do.

In the 1990s, since most of the graphics cards (devices that output computer screens to the monitor) were equipped with only D-Sub ports, there was no way to transfer digital images directly to the monitor. So, early LCD monitors still only have D-Sub interfaces. Some high-end monitors also support a Bayonet Neill-Concelman (BNC) interface with less degradation in image quality than D-Sub, but this is also an analog method, which is not a fundamental solution.

As LCD monitors became popular, a digital image interface appeared. That's why it's called DVI (Digital Visual Interface). DVI stands for an interface that can deliver digital video signals as the name suggests. As described above, DVI was first developed in 1999 by the Digital Display Working Group (DDWG), a company formed by Intel, Silicon Image, HP, Compaq and NEC. Because DDWG includes a number of leading companies in the computer industry, DVI could be deployed more quickly than expected, and most LCD monitors and graphics cards released since 2005 began to have DVI ports.

Basically, 'Single Link' standard DVI is basically configured to transmit video data to four pairs of twisted wires (two twisted cables). Each twisted pair is composed of red, green, blue And transmits digital data including three primary colors and clock (frequency) information. DVI can implement 24-bit color (16,777,216 colors) per pixel (screen point) and can display up to 1,920x1,200 resolution in 60Hz screen frequency (frequency of screen flicker per second, Screen precision) can be transmitted. With the advent of DVI, the digital image quality of LCD monitor can be easily realized.

In addition to the single-link standard, DVI also has a 'Dual Link' standard that doubles the number of internal twisted pairs and connection pins that carry video data. Dual-link DVI has a wider bandwidth than single-link DVI, so you can increase the screen frequency from 1,920x1,200 to 120Hz, and you can also achieve a high-resolution screen of 2,560x1,600 at 60Hz. To use the dual-link DVI feature, you must use a cable and graphics card that supports it.

DVI ports are divided into DVI-I and DVI-D ports depending on whether they can output analog signals, and the arrangement and number of pins are slightly different. Unlike DVI-I, a DVI port that can only output digital signals without analog signal output is also called DVI-D compliant port. The DVI-I port can be plugged into the D-Sub port by plugging in the gender

These DVI standards are widely applied to PCs and monitors, as well as commercial plasma displays and peripheral devices. For example, this DVI standard can be used for display image control of an individual space through central broadcast control of a large building, and can be used to display data of a lecturer by connecting a projector and a PC in a large classroom. In this case, a DVI connection module may be used for connection between the broadcasting control room and each individual space, or between the projector and the PC, and such a connection module may be provided through a wall installed on the wall or outside You can pass.

Also, the transmitter module 110 may include a transmitter sub module (TX Sub Module) 120.

As described above, the detachable DVI connection module 100 according to an embodiment of the present invention can connect the DVI transmission device and the DVI reception device. Accordingly, the transmitting-end module 110 is connected to the DVI transmitting device, the transmitting-end module 110 is detachably connected to the transmitting-end submodule 120, and the transmitting-end submodule 120 is connected to the cable 130 And the cable 130 is connected to the receiving module 140. Accordingly, the receiving module 140 is connected to the DVI receiving apparatus, so that the DVI transmitting apparatus and the DVI receiving apparatus are connected by the removable DVI connecting module 100 according to an embodiment of the present invention.

That is, the detachable DVI connection module 100 includes a transmitter module 110 connected to the DVI transmitter, a receiver module 140 connected to the DVI receiver, and either one of the receiver module 100 and the receiver module 110 coupled to the transmitter module 110 And a cable 130 to which the other end of the both ends is coupled with the receiving end module 140.

The transmitting end module 110 is connected to the transmitting end module 110 so as to be separated from and recombined with the transmitting end module 110. A second side different from the first side end is coupled to the cable 130, (TX Sub Module) 120 having a size smaller than that of the transmitter module 110.

In addition, the cable 130 may include any one of a glass fiber optical fiber (GOF) and a plastic optical fiber.

As shown in FIG. 2, a DVI connection module is required to transmit the DVI signal transmitted from the computer 30, which is a DVI transmission apparatus, to the projector 40. In this case, for reasons of apparentness or protection of the cable 130, the cable 130 may pass through the tube 20 which is inserted through the wall 20 and the ceiling 10.

However, since the transmitting terminal module 110 of the DVI connecting module is large in size, the cost of the tube raw material is extremely increased when the transmitting terminal module 110 generates the tube 50 so that the transmitting terminal module 110 can pass therethrough, Can take up a large volume and can have a negative effect on the aesthetic effect.
