Abstract
Provided is a quadrupled high-definition liquid crystal color screen input interface composed of a DP interface. A DP HUB is disposed at the most front end of the DP interface and is connected with two DP interface chips through two lines. The DP interface chips are connected with a same video signal processor. The DP HUB may support 4LANE with highest communication rate of 21.6G and receive a video signal of 3840*2160@60Hz. The DP HUB is connected with the DP interface chips through two DP interface signal lines which may transmit DP interface signals. The DP interface chips may convert the DP signals into RGB video data signals which are transmitted, through a signal line, to the video signal processor to be processed. With the separate flow transmission of the DP HUB and the DP interface chips, the quadrupled high-definition liquid crystal color screen input interface with simple and compact structure increases flow transmission amount, guarantees data flow to be transmitted to the video signal processor completely and losslessly, and guarantees the image quality and the refresh rate of a quadrupled high-definition liquid crystal color screen.
Description
Technical field
The utility model relates to a kind of four times of high-definition liquid crystal color screen input interfaces, and it makes four times of high definition drive plates can receive the vision signal of four times of real high definition 60Hz, belongs to electronic technology field.
Background technology
Four times of high definition LCD liquid crystal display, there is higher image quality, be subject to liking of people, but, the data traffic of four times of high definition LCD liquid crystal display is far beyond the transmittability scope of HDMI and common DP interface, and at present on the market conventional player and the high-definition interface of video card be HDMI and DP interface, by single HDMI or DP interface, cannot realize the real-time broadcasting of four times of high-definition video signals.At present comparatively general way is to reduce the refreshing frequency of screen in the industry, or simply amplifies at drive plate.These ways all be take and are damaged image quality as cost, have destroyed the picture advantage of four times of high definition LCD liquid crystal display.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model discloses a kind of four times of high-definition liquid crystal color screen input interfaces, this input interface makes four times of high definition drive plates can receive the vision signal of four times of real high definition 60Hz, thereby has significantly promoted the picture disply quality of four times of high definition LCD display.
A times high-definition liquid crystal color screen input interface, comprises DP interface, and DP interface is provided with DP HUB foremost, and DP HUB divides two-way to connect respectively two DP interface chips, and DP interface chip is connected to same video signal preprocessor.
Described DP HUB can support that the maximum support of 4LANE traffic rate is 21.6G, can receive the vision signal of 3840X2160@60Hz.
Described DP interface chip can be supported 2LANE.
Described DP HUB is connected to DP interface chip by two-way DP interface signal line, and DP interface signal line can be transmitted DP interface signal.
Described DP interface chip can change into DP signal rgb video data-signal, by holding wire, rgb video data-signal is passed to video signal preprocessor and processes.
The utility model, compact conformation, simple, distributes to two-way DP interface chip reception & disposal by four times of high definition 60HZ vision signals, by DP HUB, receives four times of high definition 60Hz vision signals.
Accompanying drawing explanation
Fig. 1 is connection status figure of the present utility model (being also the transitive graph of data traffic).
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
Explanation of nouns in this patent: DP interface refers to the coffret of high definition audio/video flow; Four times of high definition LCD display refer to four times of high-definition liquid crystal displays; HDMI refers to HDMI (High Definition Multimedia Interface); HUB refers to multiport transponder; LANE refers to LAN emulation or lan emulation; RGB refers to the color mode of coloured light, and it is red that R represents, G represent green, and B represent blueness because three kinds of colors each have 256 luminance level levels, so three kinds of color overlaids just can form 1,670 ten thousand kinds of colors (being commonly called as " very coloured silk ").
Visible by reference to the accompanying drawings, these four times of high-definition liquid crystal color screen input interfaces, comprise DP interface, and DP interface is provided with DP HUB foremost, and DP HUB divides two-way to connect respectively two DP interface chips, and DP interface chip is connected to same video signal preprocessor; Described DP HUB can support that the maximum support of 4LANE traffic rate is 21.6G, can receive the vision signal of 3840X2160@60Hz; Described DP interface chip can be supported 2LANE; Described DP HUB is connected to DP interface chip by two-way DP interface signal line, and DP interface signal line can be transmitted DP interface signal; Described DP interface chip can change into DP signal rgb video data-signal, by holding wire, rgb video data-signal is passed to video signal preprocessor and processes.
The utility model, the data traffic that is transferred to four times of high-definition liquid crystal displays is transferred to DP HUB by DP interface, data traffic is split into two parts in DP HUB, respectively by two independently data wire be transferred to DP interface chip, data traffic is converted into rgb signal in DP interface chip, rgb signal passes to video signal preprocessor, by such hardware annexation, the data traffic that can carry transmission is much larger than data passing interface in the market, realized transmission high amount of traffic amount, guaranteed the signal integrity of four times of high-definition liquid crystal color screens, can nondestructively signal be passed to video signal preprocessor, the image quality of four times of high-definition liquid crystal color screens is high, refreshing frequency is high, fluency is high.
By DP HUB, receive four times of high definition 60Hz vision signals, four times of high definition 60HZ vision signals are distributed to two-way DP interface chip reception & disposal, realized the reception of the vision signal of four times of high definition 60Hz.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technical scheme being comprised of above technical characterictic combination in any.
