Description
Technical field
The present invention relates to a kind of method that improves display quality, particularly a kind of method that improves the printed circuit boards of monitor sharing.
Background technology
Now the low-voltage differential signal interface of display pannel manufacturer mainly is divided into two kinds of single channel and binary channels, and the interface pattern is identical, and just the definition of each pin is different.Therefore printed circuit board (PCB) need to be thought of as the display pannel of these two kinds of different size interfaces when design, carries out respectively wires design, and printed circuit board (PCB) can not share like this, to having increased burden in the production management, has also increased cost of development.
For example: produce 19 cun displays of a certain model, a kind of main circuit board design, but because two display pannel manufacturer supplies of material are arranged, their interface pattern specification is different, will change like this circuit of display pannel interface on the mainboard, thereby with respectively corresponding these the two kinds of display pannels of two kinds of mainboards, increased kind and the cost of printed circuit board (PCB), also so that at the production management complicated.
In order to improve the quality of display, make its packaging technology, more reasonable structural design, continually develop the more novel product of efficient energy-saving, improve market share, become one of new problem that this field technology personnel are badly in need of solving.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, provide a kind of technique simple, density is high, dependable performance, improve product quality, improve the method for printed circuit boards of monitor sharing, to improve the utilization factor of printed circuit board (PCB), reduce system cost, reach the purpose of simplifying circuit design, enhancing productivity, reduce production costs.
The technical solution adopted in the present invention is for achieving the above object:
A kind of method that improves the printed circuit boards of monitor sharing, the implementation step that it is characterized in that the method is as follows: the P.e.c. board chip makes single channel low-voltage differential signal interface and binary channels low-voltage differential signal interface be consistent at printed circuit board wiring under the prerequisite of the single channel of low-voltage differential signal interface/binary channels pin definitions; A part realizes picture signal/clock signal/ground/unsettled carrying out four conversion by the gate that is provided with of chip internal; Can not by another part of chip internal gating realization, then add Zero-ohm resistor by the outside and carry out gating; When using single channel, this branch road resistance R 2, R3, R4, R5, R6 welding, resistance R 1 is not welded, and is off state; When using binary channels, this branch road only has resistance R 1 welding, and resistance R 2, R3, R4, R5, R6 do not weld, and are off state; Namely when using single channel, the signal electrode input end of the 17th pin of low-voltage differential signal interface, the 6th is connected with ground with the 18th pin, and while the 4th and the 5th pin is electrically connected with the confession of low-voltage differential signal; When using binary channels, the signal electrode input end of the 18th pin of low-voltage differential signal interface, the 17th pin is connected with ground, and the 4th, 5,6 pins are unsettled simultaneously.
The present invention arranges gate in each pin inside respectively, is single channel or binary channels according to the low-voltage differential signal that uses, and provides information by control signal, signal corresponding to gate output.
The invention has the beneficial effects as follows: simplified structure of the present invention, simple to operate, realize that same printed circuit board wiring can corresponding two kinds of low-voltage differential signal interfaces, reduced the kind of printed circuit board (PCB), improved its sharing, be conducive to management, efficient energy-saving reduces cost.Effective Raise production efficiency improves overall quality, simplifies technique, guarantees the consistance of machine product assembling; And be applicable to large-scale production.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to embodiment provided by the invention, structure, details are as follows for feature:
At first, illustrate that the circuit chip concrete structure that existing display comprises forms and is connected, as shown in Figure 1 and Figure 2, single channel is connected with the two-channel circuit interface.
Existing display product circuit is divided into two ingredients, under the prerequisite of low-voltage differential signal interface (single channel/binary channels) pin definitions that does not change display pannel manufacturer, make single channel low-voltage differential signal interface reach consistent with binary channels low-voltage differential signal interface at printed circuit board wiring, so just need chip internal to design to get diversification.
Such as Fig. 3, shown in Figure 5, the gate that the present invention is provided with by chip internal is realized picture signal/clock signal/ground/unsettled, four conversion, a part can not only realize by the chip internal gating, also add Zero-ohm resistor by the outside and carry out gating, represent 0ohm resistance such as the resistance that is provided with among Fig. 3, can select whether to weld according to the distinct interface of usefulness.
When using single channel, resistance R 2, R3, R4, R5, R6 welding, resistance R 1 is not welded, and is off state.
When using binary channels, only have resistance R 1 welding, resistance R 2, R3, R4, R5, R6 do not weld, and are off state.
The below illustrates mainly chip internal is how to realize the gating design:
That each pin signal is directly exported (such as Fig. 4) during the at present design of IC, and design of the present invention is described gate (such as Fig. 5) to be set to each pin inside, low-voltage differential signal according to current use is single channel or binary channels, provide information by control signal, signal corresponding to gate output.
Above-mentioned detailed description of the method for this raising printed circuit boards of monitor sharing being carried out with reference to embodiment is illustrative rather than determinate, therefore in the variation and the modification that do not break away under the general plotting of the present invention, should belong within protection scope of the present invention.
