Abstract
A quadruple-high-definition liquid crystal color screen input interface comprises a DP interface, wherein the forefront end of the DP interface is provided with a DPHUB, the DPHUB is divided into two paths which are connected with two DP interface chips respectively, and the DP interface chips are connected with the same vision signal processor. The DPHUB can support the 4LANE maximum support communication rate to be 21.6G, and can receive vision signals of 3840X2160@60Hz. The DPHUB is connected to the DP interface chips through two DP interface signal wires which can transmit DP interface signals, the DP interface chips can convert the DP signals to RGB vision data signals, and the RGB vision data signals are transmitted to the vision signal processor to process through the signal wires. The quadruple-high-definition liquid crystal color screen input interface is simple and compact in structure, through split transmission of flow of the DPHUB and the DP interface chips, transmission quantity of the flow is improved, data flow can be transmitted to the vision signal processor in good order, and image quality and refreshing frequency of a quadruple-high-definition liquid crystal color screen are guaranteed.
Description
Technical field
The present invention relates to a kind of four times of high-definition liquid crystal color screen input interfaces, 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 LCD, higher image quality is arranged, be subjected to liking of people, but, the data traffic of four times of high definition LCD LCD is the transmittability scope of HDMI and common DP interface head and shoulders above, and the player of using always on the market at present and the high definition interface of video card are HDMI and DP interface, can't realize the real-time broadcast of four times of high-definition video signals by single HDMI or DP interface.At present comparatively general way is to reduce the refreshing frequency of screen in the industry, perhaps simply amplifies at drive plate.These ways are cost to damage image quality all, have destroyed the picture advantage of four times of high definition LCD LCD.
Summary of the invention
In order to solve the problem of above-mentioned existence, the invention 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 promoted the picture display quality of four times of high definition LCD display significantly.
A kind of four times of high-definition liquid crystal color screen input interfaces comprise the DP interface, and the DP interface is provided with DP HUB foremost, and DP HUB divides two-way to connect two DP interface chips respectively, and the 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 the DP interface chip by two-way DP interface signal line, and the DP interface signal line can be transmitted the DP interface signal.
Described DP interface chip can change into the DP signal rgb video data-signal, by holding wire the rgb video data-signal is passed to video signal preprocessor and handles.
The present invention, compact conformation, simple is distributed to two-way DP interface chip with four times of high definition 60HZ vision signals and is received processing, receives four times of high definition 60Hz vision signals by DP HUB.
Description of drawings
Fig. 1 is connection status figure of the present invention (also being the transitive graph of data traffic).
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention.
Explanation of nouns in this patent: the 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 the 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, and G represent green, and B represent blue because three kinds of colors each 256 luminance level levels are arranged, so three kinds of colors superpose and just can form 1,670 ten thousand kinds of colors (being commonly called as " very coloured silk ").
By reference to the accompanying drawings as seen, these four times of high-definition liquid crystal color screen input interfaces comprise the DP interface, and the DP interface is provided with DP HUB foremost, and DP HUB divides two-way to connect two DP interface chips respectively, and the 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 the DP interface chip by two-way DP interface signal line, and the DP interface signal line can be transmitted the DP interface signal; Described DP interface chip can change into the DP signal rgb video data-signal, by holding wire the rgb video data-signal is passed to video signal preprocessor and handles.
The present invention, the data traffic that is transferred to four times of high-definition liquid crystal displays is transferred to DP HUB by the DP interface, data traffic is split into two parts in DP HUB, respectively by two independently data wire be transferred to the DP interface chip, data traffic is converted into rgb signal in the 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 in the market data passing interface, 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 height of four times of high-definition liquid crystal color screens, refreshing frequency height, fluency height.
Receive four times of high definition 60Hz vision signals by DP HUB, four times of high definition 60HZ vision signals are distributed to two-way DP interface chip receive processing, realized the reception of the vision signal of four times of high definition 60Hz.
The disclosed technological means of the present invention program is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technical scheme of being made up of above technical characterictic combination in any.
