A braided layer and an aluminum foil mylar layer are sequentially arranged in the jacket layer, at least four pairs of signal wires is arranged in the aluminum foil mylar layer, each signal wire consists of a twisted cable and a conductor, an insulator made of foamed PE (polyethylene) is arranged between each conductor and the corresponding twisted cable in each signal wire, and a ground wire which is used for reducing signal interference is arranged in each twisted cable. The aluminum foil mylar layer is arranged outside the twisted cables, and a ground wire is arranged between the braided layer and the aluminum foil mylar layer. The LVDS external connecting wire has the advantages that the wire is small in swing amplitude, low in power and adaptive to high speed and has a mechanism for reducing bus noise, the PP (propene polymer) twisted cables are conventionally used, and as for higher liquid crystal display screens, blank screens and picture flickering are avoided, and picture definition is high.
Description
Technical field
The utility model relates to a kind of external connection line, especially relates to a kind of LVDS external connection line.
Background technology
LVDS is the Low Voltage Differential Signal transmission, is a kind of new technique that current high-performance data transmission is used that satisfies; Because it can make system's supply power voltage be low to moderate 2V, therefore, it can also satisfy the following needs of using; And being used for LCDs at present, the LVDS external connection line is connected with main control module; But; The PE sizing material that this common LVDS external connection line adopts is as core insulation, and what add every pair of signal use in man-hour is the pair twist form, and its amplitude of oscillation is big and power is all bigger; Be difficult to adapt to two-forty, also do not reduce the mechanism of bus noise.Common LVDS external connection line The performance test results; Its differential impedance (Differential Impedance) is 100 Ω ± 10 Ω/200ps (cable); Transmission delay differences (Skew) is 200 ps/m (max); And decay (Attenuation), near-end loss (NEXT), long-range loss (NEXT), volume of transmitted data (Data Rate) are all only greater than 3.5Gbps; Higher relatively LCDs has the phenomenon that blank screen or picture are beated sometimes, therefore can not satisfy the demand of existing product.
Summary of the invention
The utility model technical problem to be solved provides a kind of ability and realizes that being used for LCDs is connected with main control module; Import LCDs fast into assurance master control mould image and signal, and tool reaches the LVDS external connection line of the clear degree of superelevation of its pixel.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme.
This LVDS external connection line; Comprise that cross section is circular serving; Be disposed with braid in the serving and the aluminium foil wheat is drawn layer; Said aluminium foil wheat is drawn and is provided with the holding wire that is made up of twisted pair wire and conductor in the layer, is provided with the insulator that foaming PE processes between lead in the said holding wire and the twisted pair wire, and is provided with the ground wire that is used for reducing the signal interference in the twisted pair wire.
In order to increase the shielding properties of holding wire, further, said twisted pair wire outer setting has the aluminium foil wheat to draw layer.
In order to reduce the influence to signal of decay, cross-talk, more further, said braid and aluminium foil wheat are drawn and are provided with ground wire between the layer.
In order to guarantee the transmission performance of signal, further, said holding wire has four pairs at least.
Compared with prior art, the usefulness of the utility model is: this LVDS external connection line amplitude of oscillation is little, power is little, can adapt to two-forty; And has the mechanism that reduces the bus noise; Realize that conventional what use is PP pair twist heart yearn, during higher relatively LCDs, the phenomenon that blank screen and picture are beated can not occur; And image sharpness is very high.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model LVDS external connection line end face structure sketch map.
Among the figure: 1, serving; 2, braid; 3, the aluminium foil wheat is drawn layer, and 3-1, aluminium foil wheat are drawn layer;
4, holding wire, 4-1, twisted pair wire; 5, conductor; 6, ground wire, 6-1, ground wire;
7, insulator.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail:
A kind of LVDS external connection line shown in Figure 1; Comprise that cross section is circular serving 1; Be disposed with braid 2 in the serving 1 and draw layer 3 with the aluminium foil wheat; Said aluminium foil wheat is drawn in the layer 3 and is provided with the holding wire 4 that is made up of twisted pair wire 4-1 and conductor 5, and said holding wire 4 has four pairs at least, and is provided with the insulator 7 that foaming PE processes between lead 5 in the holding wire 4 and the twisted pair wire 4-1; And be provided with among the twisted pair wire 4-1 and be used for reducing the ground wire 6-1 that signal disturbs, reduced the influence to signal of decay, cross-talk; In order to increase the shielding properties of holding wire, said twisted pair wire 4-1 outer setting has the aluminium foil wheat to draw a layer 3-1; Said braid 2 and aluminium foil wheat are drawn between the layer 3 and are provided with ground wire 6, guarantee the stability of signal.
LVDS external connection line performance after the improvement is through test; Its differential impedance (Differential Impedance) is 100 Ω ± 10 Ω/200ps (cable); Transmission delay differences (Skew) is 111 ps/m (max), and the loss of decay (Attenuation), near-end (NEXT), long-range loss (NEXT), volume of transmitted data (Data Rate) are all greater than 5.1Gbps; Therefore, the amplitude of oscillation is little, power is little, can adapt to two-forty; And have the mechanism that reduces the bus noise, what realize conventional use is PP pair twist heart yearn, higher relatively LCDs; Sometimes have the phenomenon that blank screen or picture are beated. but be to use this product; Can this phenomenon of type of appearance, and image sharpness is very high.
It is emphasized that: above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
